IT MADE US TO WORRY

Information technology (IT), as defined by the Information Technology Association of America (ITAA), is "the study, design, development, implementation, support or management of computer-based information systems, particularly software applications and computer hardware." IT deals with the use of electronic computers and computer software to convert, store, protect, process, transmit, and securely retrieve information.

Today, the term information technology has ballooned to encompass many aspects of computing and technology, and the term has become very recognizable. The information technology umbrella can be quite large, covering many fields. IT professionals perform a variety of duties that range from installing applications to designing complex computer networks and information databases. A few of the duties that IT professionals perform may include data management, networking, engineering computer hardware, database and software design, as well as the management and administration of entire systems.

When computer and communications technologies are combined, the result is information technology, or "infotech". Information Technology (IT) is a general term that describes any technology that helps to produce, manipulate, store, communicate, and/or disseminate information. Presumably, when speaking of Information Technology (IT) as a whole, it is noted that the use of computers and information are associated.

The term Information Technology (IT) was coined by Jim Domsic of Michigan in November 1981.[citation needed] Domsic created the term to modernize the outdated phrase "data processing". Domsic at the time worked as a computer manager for an automotive related industry.In recent years ABET and the ACM have collaborated to form accreditation and curriculum standards for degrees in Information Technology as a distinct field of study separate from both Computer Science and Information Systems. SIGITE is the ACM working group for defining these standards.

Although reports of an "information explosion" date back to at least the era of Vannevar Bush, the increasing abundance of information at the start of the new millennium seems daunting.3 Lyman and Varian’s 2003 study estimated that new stored information grew at a rate of approximately 30 percent annually between 1999 and 2002.4 Most new information is stored in digital form, and an increasing percentage of analog materials are being migrated from analog to digital. No wonder educators, librarians, researchers, futurists, and business and government leaders worry about our citizens’ abilities to effectively deal with this expanding—and mostly digital—volume of information.

Use of the Internet is just one example of the influx of information technology into our daily lives. According to the Pew Internet and American Life Project, in December 2003 fully 63 percent of adult Americans and three-quarters of those aged 12 to 17 reported using the Internet.5 Characteristic activities differ among various categories of users but typically include e-mail, information seeking, and electronic commerce.


Problems with Reaching IT Fluency Goals

In their book Higher Education in the Digital Age, Duderstadt, Atkins, and Van Houweling asserted that although information technology has affected nearly every segment of society—from corporations to governments—higher education provides a stark contrast: "To date, the university stands apart, almost unique in its determination to moor itself to past traditions and practices, to insist on performing its core teaching activities much as it has in the past."18 The lecture method is literally unchanged from its introduction centuries ago, and many technology innovations remain in limited use.

The available data to a large degree support their contentions regarding the use of IT within academe. The Green study, for example, reported relatively low use of computer-based classrooms/labs (32.1 percent of classes), course management tools for online course resources (33.6 percent), and Web pages for class materials (37.4 percent of classes).19 With an average of 82 percent of campuses providing access to a CMS, this suggests a tremendous underutilization of an expensive campus investment. More encouraging signs include the incorporation of e-mail (in 71.8 percent of classes) and Internet resources (in 52.9 percent of classes). Given that e-mail is the most popular use of the Internet, followed closely by information seeking, these findings simply tend to parallel larger societal trends, however.20

A smaller-scale qualitative study at the University of Washington (UW) provides an additional perspective to consider in assessing the state of IT in at least one higher education learning environment.21 Through multidisciplinary focus groups of approximately 100 faculty and students, UW’s Program for Educational Transformation Through Technology expanded on a 2001 survey of faculty educational technology practices. Students emphasized their expectations for the integration of technology into their education and expressed concern that these expectations were not being met. Specific technologies considered important by students included course Web sites (perhaps mandatory for all classes); effective (emphasis added) faculty use of PowerPoint; discussion boards; e-mail as the primary mode of communication with faculty; and Web-based research resources. Other technologies and instructional methods valued by students included instant messaging, Microsoft Excel, the use of video clips to reinforce lecture material, and hands-on, self-paced, progressive learning opportunities.

Faculty in this study also considered PowerPoint, discussion boards, and Web-based research important. More striking, however, were the faculty concerns about overcoming the barriers to implementation of these technologies into their curricula. Perceived barriers included their own lack of skill, equipment, and time. Further, the wide range of skill levels among faculty was viewed as hindering communication with departmental colleagues; many individuals simply did not feel comfortable with the culture of educational technology. Faculty perceptions reported in this study are particularly interesting in view of the strong emphasis at UW on faculty technology support through various components of its UWired initiative.

IT funding continues to be a serious campus challenge according to both the "Fifth Annual EDUCAUSE Survey on IT Issues" and the Green study. However, "assisting faculty in integrating technology into instruction" was considered to be the single most important IT challenge (out of 10 options) over the next several years according to Green respondents (21.4 percent).22 "Faculty development, support, and training" were similarly ranked 5 and 6, respectively, out of 10 of the top IT issues in the EDUCAUSE survey.23 Given the competition from such areas as funding, security, administrative systems, and network maintenance, the placement of a relatively "soft" issue among the top 10 by EDUCAUSE respondents signals an acknowledgement of its importance in a time of burgeoning costs, technical complications, and rising expectations for technical infrastructure.

Outsourcing of work to low cost developing nations is growing rapidly even after constant challenges it faces from government and lawmakers of developed countries.
Last 6 years have seen India become the Outsourcing hub of the world and trend seem to be continuing for few years to come. The latest estimates released by National Association of Software and Services companies (Nasscom), projects revenues at $40 billion for this fiscal year. The report also says that, software and services sector should achieve $60bn in export revenue by 2009/2010. Having one of the youngest and largest English speaking well educated populations in the world is just a couple of reasons (of many) on why India is the front runner in this knowledge Industry.

However, some researches like the one prepared by IDC predict that China may overtake India in IT offshoring as early as 2011. Ofcourse, I do not buy that. Not because I am an Indian, but I sincerely think China does not have what it takes to overtake India in IT sector in next 4 years as put forth by the IDC Global Delivery Index.
Here is an excerpt from the IDC report.

Honestly speaking, Mumbai and Bangalore are not the cities that should be even considered now, as these places are completely saturated, but Tier I and II cities in India are having the biggest potential for growth. Cities like Pune, Ahmedabad, Cochin, Mysore, Chandigarh, Patna, Nagpur, and many more are the cities that need to be included in the Global Delivery Index. I bet they will rank much higher on this index than any of the other Asia-Pacific cities. Even if you consider the difference in cost of setting up delivery center in Between Bangalore and Pune/Ahmedabad, it would be less than a half. If you talk to most HR experts, they will tell you that you can find good people resources easily in Tier II cities as compared to Mumbai and Bangalore.

International Olympic Committee

The International Olympic Committee (French: Comité International Olympique) is an organization based in Lausanne, Switzerland, created by Pierre de Coubertin and Demetrios Vikelas on June 23, 1894. Its membership consists of the 205 National Olympic Committees.The IOC organizes the modern Olympic Games held in Summer and Winter, every four years. The first Summer Olympics organized by the International Olympic Committee held in Athens, Greece, in 1896; the first Winter Olympics in Chamonix, France, in 1924. Until 1992, both Summer and Winter Olympics were held in the same year. After that year, however, the IOC shifted the Winter Olympics to the even years between Summer Games, to help space the planning of the two events two years apart from one another.

On June 23, 1894 the Olympic games were re-created by Pierre de Coubertin after a hiatus of 1500 years. The baron hoped to foster international communication and peace through the Olympic Games. The IOC is a parent organization intended to localize administration and authority for the Games, as well as to provide a single legal entity which owns copyrights, trademarks, and other intangible properties associated with the Olympic games. For example, the Olympic logos, the design of the Olympic flag, the motto, creed, and anthem are all owned and administered by the IOC. There are other organizations which the IOC coordinates as well, which are collectively called the Olympic Movement. The IOC President is responsible for representing the IOC as a whole, and there are members of the IOC which represent the IOC in their respective countries.

Professor David C. Young of the University of Florida has conducted research suggesting that the revival of the modern Olympic Games was planted firmly in both Greece and the United Kingdom by Evangelos Zappas and Dr William Penny Brookes respectively.The IOC Executive Board consists of the President, four Vice-Presidents and ten other members. All members of the IOC Executive Board are elected by the Session, in a secret ballot, by a majority of the votes cast. The IOC Executive Board assumes the general overall responsibility for the administration of the IOC and the management of its affairs.

The IOC Session elects, by secret ballot, the IOC President from among its members for a term of eight years renewable once for four years. The next President election will then take place in 2009. The President represents the IOC and presides over all its activities. Former President Juan Antonio Samaranch has been elected Honorary President For Life.

In addition to the Olympic medals for competitors, the IOC awards a number of other honours:
* the IOC President's Trophy is the highest sports award given to athletes who have excelled in their sport and had an extraordinary career and created a lasting impact on their sport.
* the Pierre de Coubertin medal is awarded to athletes who demonstrate a special spirit of sportsmanship in Olympic events
* the Olympic Cup is awarded to institutions or associations with a record of merit and integrity in actively developing the Olympic Movement
* the Olympic Order is awarded to individuals for particularly distinguished contributions to the Olympic Movement, and superseded the Olympic Certificate.

For most of its existence, the IOC was controlled by members who were co-opted, which means they were selected by other members. Countries that had hosted the Games were allowed two members, others one or none. When named, they became not representatives of their respective countries to the IOC, but rather the opposite, IOC members in their respective countries.

For a long time, members of royalty have been members of co-option, such as Prince Albert de Monaco, as have former athletes. These last 10 years, the composition has evolved, in order to get a better representation of the sports world. Members seats have been allocated specifically to athletes, International Federations leaders and National Olympic Committees leaders.

The Olympic Movement generates revenue through five major programs. The International Olympic Committee (IOC) manages broadcast partnerships and the TOP worldwide sponsorship program. The Organizing Committees for the Olympic Games (OCOGs) manage domestic sponsorship, ticketing and licensing programs within the host country under the direction of the IOC. The Olympic Movement generated a total of more than US$4 billion in revenue during the most recent Olympic quadrennium (2001–2004).

The IOC is now the largest single revenue source for the majority of IFs, with its contributions of Olympic broadcast revenue that assist the IFs in the development of their respective sports worldwide. The IOC provides financial support from Olympic broadcast revenue to the 28 IFs of Olympic summer sports and the seven IFs of Olympic winter sports after the completion of the Olympic Games and the Olympic Winter Games, respectively.

The continually increasing value of Olympic broadcast partnership has enabled the IOC to deliver substantially increased financial support to the IFs with each successive Games. The seven winter sports IFs shared US$85.8 million in Salt Lake 2002 broadcast revenue. The contribution to the 28 summer sports IFs from Athens 2004 broadcast revenue has not yet been determined, but the contribution is expected to mark a significant increase over the US$190 million that the IOC provided to the summer IFs following Sydney 2000.

Audit

The most general definition of an audit is an evaluation of a person, organization, system, process, project or product. Audits are performed to ascertain the validity and reliability of information, and also provide an assessment of a system's internal control. The goal of an audit is to express an opinion on the person/organization/system etc. under evaluation based on work done on a test basis. Due to practical constraints, an audit seeks to provide only reasonable assurance that the statements are free from material error. Hence, statistical sampling is often adopted in audits. In the case of financial audits, a set of financial statements are said to be true and fair when they are free of material misstatements - a concept influenced by both quantitative and qualitative factors.

Traditionally audits were mainly associated with gaining information about financial systems and the financial records of a company or a business (see financial audit). However recently auditing has begun to include other information about the system, such as information about environmental performance. As a result there are now professions that conduct environmental audits.In financial accounting, an audit is an independent assessment of the fairness by which a company's financial statements are presented by its management. It is performed by competent, independent and objective person or persons, known as auditors or accountants, who then issue an auditor's report on the results of the audit.

Such systems must adhere to generally accepted standards set by governing bodies that regulate businesses. It simply provides assurance for third parties or external users that such statements present 'fairly' a company's financial condition and results of operations.Quality audits are performed to verify the effectiveness of a quality management system. This is part of certifications such as ISO 9001. They are essential to verify existence of objective evidence of processes, to assess how successfully processes have been implemented, for judging the effectiveness of achieving any defined target levels, provide evidence concerning reduction and elimination of problem areas, and are a hands-on management tool for achieving continual improvement in an organisation.

For the benefit of the organization, quality auditing should not only report non-conformances and corrective actions, but also highlight areas of good practice. In this way other departments may share information and amend their working practices as a result, also enhancing continual improvement.n the US, audits of publicly-listed companies are governed by rules laid down by the Public Company Accounting Oversight Board (PCAOB). Such an audit is called an Integrated Audit, and auditors have the additional responsibilities of expressing opinions on management's assessment of the firm's internal control, and on the effectiveness of internal control over financial reporting based on their (the auditors') own assessment.

While the four major audit firms listed above provide audit services to the largest corporations in America, audit firms around the world are also in partnership with the Big Four. Since corporations held offices in other parts of the world, they tend to be audited by affiliates of the Big Four to maintain consistency and uniformity in their application of auditing standards.

Accountant

An accountant is a practitioner of accountancy, which is the measurement, disclosure or provision of assurance about financial information that helps managers, investors, tax authorities and other decision makers make resource allocation decisions.In many countries the designation accountant, or at least the more specific terms qualified accountant or professional accountant, is a certified accountancy and financial expert. Like other legally restricted professions including doctors and lawyers, different countries have their own training and examination systems to maintain the quality of qualified accountants in their jurisdictions. There are many professional bodies for accountants throughout the world.

Accountants originally worked only in public practice, i.e. professional accountancy firms, selling advice and services to other individuals and businesses. Today, in addition, many work within private corporations, the financial industry and various government bodies.the requirements for entry in the profession of accounting vary from country to country.Accountants may be licensed by a variety of organizations, and are recognized by titles such as Chartered Certified Accountant, Chartered Accountant, Certified Public Accountant, Certified Management Accountant, Certified General Accountant and Certified Practicing Accountant. Many countries recognize two or more accounting bodies. There is, however, no legal requirement for an accountant to be a paid-up member of one of the many Institutes and other bodies which are effectively a form of professional trade union. Unlike the Law Society, which can legally stop a solicitor from practicing, accountancy institutes do not have such authority. Generally, certain specialized areas of accountancy such as auditing and insolvency are tightly regulated.

The Certified Management Accountant (CMA) designation is unusual in the United States in that it does not have a statutory basis. However, it is accepted by industry and by its peer associations. In Canada the Canadian CMA designation is recognised under provincial/territorial legislation.In the United Kingdom, Canada, Australia and several other Commonwealth of Nations countries, the equivalents of Certified Public Accountant (CPA) include Chartered Certified Accountant (ACCA), Chartered Accountant (CA or ACA), Chartered Management Accountant, International Accountant, Certified Public Accountant (CPA - Ireland and CPA - Hong Kong), Certified General Accountant (CGA - Canada), and Certified Practicing Accountant (CPA - Australia).
In Canada, there are three recognized accounting bodies: the Canadian Institute of Chartered Accountants (CA) and the provincial and territorial CA Institutes, the Certified General Accountants Association of Canada (CGA), and the Society of Management Accountants of Canada, also known as the Certified Management Accountants (CMA). CA and CGA were created by Acts of Parliament in 1902 and 1913 respectively and CMA was established in 1920.

The CA program focuses on public accounting and candidates must obtain auditing experience from public accounting firms; the CGA program takes a general approach allowing candidates to focus in their own financial career choices; the CMA program focuses in management accounting. The CA and CMA programs require a candidate to obtain a degree as a program entry requirement. The CGA program requires a degree as an exit requirement prior to certification.

Auditing and Public Accounting are regulated by the provinces. Historically, only CAs can perform audits in Ontario. In 2004, the provincial government of Ontario passed a new Public Accounting Act that would allow qualified CGAs and CMAs to perform audits, conditional on their organizations being able to demonstrate that their qualification and regulatory programs are equivalent in rigour to that of the CA program. As of March 2006, this process of evaluation had not yet begun. In Quebec as well, CAs still have exclusive public company audit rights by statute. In British Columbia and Prince Edward Island, CAs and CGAs have equal status regarding public accounting and auditing; In the rest of Canada, CAs, CGAs, and CMAs are considered equivalents pursuant to provincial and territorial legislation.

Flight attendant

Flight attendants or cabin crew (historically known as stewards, air hosts/hostesses, or stewardesses) are members of an aircrew employed by airlines to ensure the safety and comfort of the passengers aboard commercial flights as well as on select business jet aircraft.The primary and overriding responsibility of flight attendants is passenger safety. They are often tasked with the secondary function of seeing to the care and comfort of the passengers, insofar as this does not interfere with their safety responsibilities. They are often perceived by the flying public as waiting staff or servants because there is not a full understanding of the career, the majority of their regular and rare duties are safety related and are the priority above customer service.

The majority of a flight attendant's duties are safety related. Prior to each flight, flight attendants attend a safety briefing with the pilots & purser. During this briefing they go over safety and emergency checklists, the locations and amounts of emergency equipment and other features specific to that aircraft type. Boarding particulars are verified, such as special needs passengers, small children travelling as unaccompanied minors or VIP's. Weather conditions are discussed including anticipated turbulence. Prior to each flight a safety check is conducted to ensure all equipment such as lifevests, flashlights and firefighting equipment are on board, in the right quantity, and in proper condition. Any unserviceable or missing items must be reported and rectified prior to takeoff. They must monitor the cabin for any unusual smells or situations and maintain certain precautions such as keeping doors disarmed or open during fueling on the ground. They assist with the loading of carry-on baggage, checking for weight, size and dangerous goods. They then must do a safety demonstration or monitor passengers as they watch a safety video demonstrating the safety features of the aircraft. They then must "secure the cabin" ensuring tray tables are stowed, seats are in their upright positions, armrests down and carry ons stowed correctly and seatbelts fastened prior to takeoff.

Flight attendants must conduct cabin checks every 20-30 minutes, especially during night flights to check on the passengers, and listen for any unusual noises or situations. Checks must also be done on the lavatory to ensure the smoke detector hasn't been deactivated, there are no issues with the equipment, nobody having trouble in there or smoking, and to restock supplies as needed. Regular cockpit checks must be done to ensure the pilot's health and safety. They must respond immediately to call lights dealing with special requests and smaller emergencies including a wide variety of inflight emergencies that do happen from time to time and special requests. During turbulence crosschecks must be conducted and during severe turbulence all service equipment must also be stowed. Prior to landing all loose items, trays and garbage must be collected and secured along with service and galley equipment. All hot liquids must be disposed of. A final crosscheck must then be completed prior to landing. They must remain aware as the majority of mechanical emergencies occur during takeoff and landing. Upon landing, flight attendants must remain stationed at exits and monitor the airplane and cabin as passengers disembark the plane. They also assist any special needs passengers and small children off the airplane and escort children, while following the proper paperwork and ID process to escort them to the designated person picking them up.

Flight attendants are highly trained for a wide variety of emergencies and how to respond. More frequent situations may include a bleeding nose, illness, small injuries, intoxicated passengers, aggressive and anxiety stricken passengers. Emergency training includes rejected takeoffs, emergency landings, cardiac and inflight medical situations, smoke in the cabin, fires, depressurization, onboard births and deaths, dangerous goods and spills in the cabin as well as land and water landings including the preparation of passengers and the cabin, the evacuation with slides or rafts and then the followup survival skills which include environments as open water, jungle, water, tropical and Arctic climates, along with a variety of emergency equipment.Many regions mandate the presence of flight attendants on commercial aircraft, based on the passenger capacity of the aircraft and other factors. This mandate generally relates only to their function as safety technicians.

The main and always primary duty of a flight attendant is for safety but they do also provide a caregiving and customer service role on board commercial flights. Customer service duties include the preparation and serving or selling of onboard food and beverage. Flight attendants also offer comfort items including blankets, pillows, hot towel service, handing out headsets, magazines, newspapers, amenity kits, games and on certain airlines hand out pyjamas and set up and make the lie flat beds. They also distribute customs forms on international flights and assist passengers with their proper completion prior to landing.

Multilingual flight attendants are often in demand to accommodate international travelers. The languages most in demand, other than English, are Mandarin, Cantonese, Japanese, Hindi, Arabic, French, German, Spanish, Portuguese, Filipino, Indonesian and Italian. In the United States, airlines with international routes pay an additional stipend for language skills on top of flight pay, and some airlines hire specifically for certain language when launching international destinations.

Some airlines, such as EVA Air, have height requirements for purely aesthetic purposes. Horizon Air and other regional carriers have height restrictions because their aircraft have low ceilings.Flight attendants are also subject to weight requirements as well. Weight must usually be in proportion to height; persons outside the normal range may not be qualified to act as flight attendants.

Singing

Singing is the act of producing musical sounds with the voice, which is often contrasted with speech. A person who is singing is called a singer or vocalist. Singers perform music known as songs that can either be sung a cappella (without accompaniment) or accompanied by musicians and instruments. Singing is often done in a group, such as a choir. Nearly anyone who can speak can sing, since in many respects singing is merely a form of sustained speech. It can be informal and just for pleasure, for example, singing in the shower or karaoke; or it can be very formal, such as singing done professionally as a performance or in a recording studio. Singing at a high amateur or professional level usually requires a certain amount of innate talent and a great deal of regular practice, and/or instruction. Professional singers usually build their careers around one specific musical genre and undergo voice training, provided by a voice teacher or coach throughout a career.

In its physical aspect, singing has a well-defined technique that depends on the use of the lungs, which act as an air supply, or bellows; on the larynx, which acts as a reed or vibrator; on the chest and head cavities, which have the function of an amplifier, as the tube in a wind instrument; and on the tongue, which together with the palate, teeth, and lips articulate and impose consonants and vowels on the amplified sound. Though these four mechanisms function independently, they are nevertheless coordinated in the establishment of a vocal technique and are made to interact upon one another. During passive breathing, air is inhaled with the diaphragm while exhalation occurs without any effort. Exhalation may be aided by the abdominal, internal intercostal and lower pelvic muscles. Inhalation is aided by use of external intercostals, scalenes and sternocleidomastoid muscles. The pitch is altered with the vocal cords. With the lips closed, this is called humming.

The sound of each individual's singing voice is entirely unique not only because of the actual shape and size of an individual's vocal cords but also due to the size and shape of the rest of that person's body. Humans have vocal folds which can loosen, tighten, or change their thickness, and over which breath can be transferred at varying pressures. The shape of the chest and neck, the position of the tongue, and the tightness of otherwise unrelated muscles can be altered. Any one of these actions results in a change in pitch, volume, timbre, or tone of the sound produced. Sound also resonates within different parts of the body, and an individual's size and bone structure can affect the sound produced by an individual.

Singers can also learn to project sound in certain ways so that it resonates better within their vocal tract. This is known as vocal resonation. Another major influence on vocal sound and production is the function of the larynx which people can manipulate in different ways to produce different sounds. These different kinds of laryngeal function are described as different kinds of vocal registers. The primary method for singers to accomplish this is through the use of the Singer's Formant; which has been shown to match particularly well to the most sensitive part of the ear's frequency range.

Vocal resonation is the process by which the basic product of phonation is enhanced in timbre and/or intensity by the air-filled cavities through which it passes on its way to the outside air. Various terms related to the resonation process include amplification, enrichment, enlargement, improvement, intensification, and prolongation, although in strictly scientific usage acoustic authorities would question most of them. The main point to be drawn from these terms by a singer or speaker is that the end result of resonation is, or should be, to make a better sound. There are seven areas that may be listed as possible vocal resonators. In sequence from the lowest within the body to the highest, these areas are the chest, the tracheal tree, the larynx itself, the pharynx, the oral cavity, the nasal cavity, and the sinuses.

Chest voice and head voice are terms used within vocal music. The use of these terms varies widely within vocal pedagogical circles and there is currently no one consistent opinion among vocal music professionals in regards to these terms. Chest voice can be used in relation to a particular part of the vocal range or type of vocal register; a vocal resonance area; or a specific vocal timbre. Head voice can be used in relation to a particular part of the vocal range or type of vocal register or a vocal resonance area

Singing is not a natural process but is a skill that requires highly developed muscle reflexes. Singing does not require much muscle strength but it does require a high degree of muscle coordination. Individuals can develop their voices further through the careful and systematic practice of both songs and vocal exercises. Vocal pedagogists instruct their students to exercise their voices in an intelligent manner. Singers should be thinking constantly about the kind of sound they are making and the kind of sensations they are feeling while they are singing.

here are several purposes for vocal exercises, including warming up the voice; extending the vocal range; "lining up" the voice horizontally and vertically; and acquiring vocal techniques such as legato, staccato, control of dynamics, rapid figurations, learning to sing wide intervals comfortably, singing trills, singing melismas and correcting vocal faults.

Nurse

A nurse is responsible—along with other health care professionals—for the treatment, safety, and recovery of acutely or chronically ill/injured people, health maintenance of the healthy, and treatment of life-threatening emergencies in a wide range of health care settings. Nurses may also be involved in medical and nursing research and perform a wide range of non-clinical functions necessary to the delivery of health care. Nurses also provide care at birth and death. There is currently a shortage of nurses in the United Kingdom, United States and a number of other developed countries.

The nursing career structure varies throughout the world. Typically there are several distinct levels of nursing practitioner distinguished by scope of practice. The major distinction is between task-based nursing and professional nursing. Nurses throughout the world are increasingly employed as registered nurses, advanced practice nurses, clinical nurse specialists and nurse practitioners. At the top of the educational ladder is the doctoral-prepared nurse. Nurses may gain a PhD or another doctoral degree, specializing in research, clinical nursing, and so forth. These nurses practice nursing, teach nursing, and carry out nursing research. As the science and art of nursing has advanced, so has the demand for doctoral-prepared nurses.

In various parts of the world, the educational background for nurses varies widely. In some parts of eastern Europe, nurses are high school graduates with twelve to eighteen months of training. In contrast, Chile requires any registered nurse to have at least a bachelor's degree.Nurses are the largest group of providers in the health care system--there are over two million registered nurses in the United States of America (U.S.) alone, comprising about 13% of the fifteen million workers in the health care and social assistance category tracked by the U.S. Department of Labor.

Nursing is one of the most female-dominated occupations, but the number of males entering the profession is increasing. For example, in 2000 only 5.4% of registered nurses in the U.S. were male, however, that percentage represents a 226% increase over the previous two decades. In 2007, internationally, 10.7% of registered nurses and 10.4% of licensed practical nurses were male.Although the rise in the number of males entering and working in the nursing profession is an ongoing trend, females continue to predominate in nursing, as well as in the health care sector as a whole.Governments regulate the profession of nursing to protect the public.

The Indian Nursing Council is the regulatory body for the profession of nursing. A person practicing nursing must be registered with the nursing council. For a person to be registered, he or she has to undergo and pass the prescribed course stipulated by the council. In India, diplomas, bachelor degrees(B.Sc Nursing), postgraduate degrees(M.Sc Nursing) and Doctorates (PhD) are offered.

Some postgraduate nursing specialities include medical, pediatric, obstetric, surgical and community health nursing which are offered by a large number of colleges and universities throughout India. Some institutes such as the National Institute of Mental Health and Neurological Sciences (NIMHANS) offer specialization in psychiatric nursing, neurosurgical nursing.

The nursing staff at institutes and hospitals are segregated into teaching and clinical divisions. In the clinical division, the nurses' stages are- ward nurse, nursing superintendent grade 3, nursing superintendent grade 2, and nursing superintendent grade 1. And in the teaching section they are called nursing tutor grade 2 and grade 1.

Bookselling

Bookselling is the commercial trading of books, the retail and distribution end of the publishing process. People who engage in bookselling are called booksellers or bookmen.Bookstores can range in size offering from several hundred to several hundred thousands of titles. They may be brick-and-mortar stores or internet only stores or a combination of both. Sizes for the larger bookstores exceed half a million titles.

Bookstores often sell other printed matter besides books, such as newspapers and maps; additional product lines may vary enormously, particularly among independent bookstores. Colleges and universities often have their own student bookstore on campus that focuses on providing course textbooks and scholarly books, although some on-campus bookstores are owned by large chains such as Waterstone's in the United Kingdom, or Barnes & Noble College Booksellers in the United States, which is a private firm controlled by the chair of Barnes & Noble.

Another common type of bookstore is the used bookstore or second-hand bookshop which buys and sells used and out-of-print books. A range of titles are available in used bookstores, including in print and out of print books. Book collectors tend to frequent used book stores. Large online bookstores offer used books for sale, too. Individuals wishing to sell their used books using online bookstores agree to terms outlined by the bookstore(s): for example, paying the online bookstore(s) a predetermined commission once the books have sold.Some bookstores have a policy of destroying their older inventory in order to get a credit from the publisher.

The high degree of learning and scholarship in the medieval Islamic world, particularly during the Abbasid Caliphate in the east and Caliphate of Córdoba in the west, encouraged the development of bookshops, copyists, and book dealers across the entire Muslim world, in Islāmic cities such as Damascus, Baghdad, and Córdoba. According to Encyclopædia Britannica: "Scholars and students spent many hours in these bookshop schools browsing, examining, and studying available books or purchasing favourite selections for their private libraries. Book dealers traveled to famous bookstores in search of rare manuscripts for purchase and resale to collectors and scholars and thus contributed to the spread of learning. Many such manuscripts found their way to private libraries of famous Muslim scholars such as Avicenna, al-Ghazālī, and al-Fārābī, who in turn made their homes centres of scholarly pursuits for their favourite students."

For later times it is necessary to make a gradual distinction between booksellers, whose trade consists in selling books, either by retail or wholesale, and publishers, whose business involves the production of the books from the author's manuscripts, and who are the intermediaries between author and bookseller, just as the booksellers (in the restricted sense) are intermediaries between the author and publisher and the public. The convenience of this distinction is not impaired by the fact either that a publisher is also a wholesale bookseller, or that a still more recent development in publishing started a reaction to some extent in the way of amalgamating the two functions. The scheme of The Times Book Club (started in 1905) was, again, a combination of a subscription library with the business of bookselling and it brought the organization of a newspaper, with all its means of achieving publicity, into the work of pushing the sale of books, in a way which practically introduced a new factor into the bookselling business.

During the 19th century it remains the fact that the distinction between publisher and bookseller--literary promoter and shopkeeper--became fundamental. The booksellers, as such, were engaged either in wholesale bookselling, or in the retail, the old or second-hand, and the periodical trades.

Coming between the publisher and the retail bookseller is the important distributing agency of the wholesale bookseller. It is to him that the retailer looks for his miscellaneous supplies, as it is simply impossible for him to stock one-half of the books published. In Paternoster Row, London, which has for over a hundred years been the centre of this industry, may be seen the collectors from the shops of the retail booksellers, busily engaged in obtaining the books ordered by the book-buying public. It is also through these agencies that the country bookseller obtains his miscellaneous supplies. At the leading house in this department of bookselling almost any book can be found, or information obtained concerning it. At one of these establishments over 1,000,000 books are constantly kept in stock. It is here that the publisher calls first on showing or "subscribing" a new book, a critical process, for by the number thus subscribed the fate of a book is sometimes determined.

What may be termed the third partner in publishing and its ramification is the retail bookseller; and to protect his interests there was established in 1890 a London booksellers' society, which had for its object the restriction of discounts to 25%, and also to arrange prices generally and control all details connected with the trade. The society a few years afterwards widened its field of operations so as to include the whole of the United Kingdom, and its designation then became "The Associated Booksellers of Great Britain and Ireland."

Business magnate

A business magnate, sometimes referred to as a mogul, tycoon, baron, or industrialist, is a person who has reached a prominent place in a particular industry (or set of industries) and whose wealth has been derived primarily therefrom. Such people usually amass substantial fortunes in the process, and tend to become widely known in connection with their business(es) or through other pursuits such as philanthropy. The terms "mogul", "tycoon" and "baron" were often attributed to late 19th and early 20th century North American business magnates in extractive industries such as mining, logging and petroleum, transportation fields such as shipping and railroads, manufacturing—including steelmaking, banking, and newspaper publishing. This era was known as the Second Industrial Revolution or the Gilded Age.

Examples of well-known business magnates include utility and transportation magnate Samuel Insull, newspaper magnate William Randolph Hearst of the Hearst Corporation, oil magnate John D. Rockefeller of Standard Oil, steel magnate Lakshmi Nivas Mittal of Mittal Steel, software magnate Bill Gates of Microsoft and poultry magnate Frank Perdue of Perdue Farms.In Russia and some other post-Soviet countries, the term "business oligarch" has become popular.

The word tycoon is derived from the Japanese word taikun (大君, taikun?), which means "great lord," and it was used as a title for the shogun. The word entered the English language in the nineteenth century with the return of Commodore Perry to the United States. U.S. President Abraham Lincoln was humorously referred to as the Tycoon by his aides John Nicolay and John Hay. The term spread to the business community, where it has been used ever since.

The word mogul originally meant Mongol, or person of Mongolian descent. In this context, it refers to the Mughal Empire (mughal being Persian or Arabic for "Mongol") of India that existed between 1526 and 1857: the early Mughal emperors claimed a heritage dating back to Mongol ruler Genghis Khan . The modern meaning of the word is supposedly derived from the storied riches of the Mughal emperors, which for example produced the Taj Mahal.

The word magnate itself derives from the Latin word magnates (plural of magnas), meaning "great person" or "great nobleman."As the term industrialist (from Latin industria, "diligence, industriousness") was more widely used in the context of "old world" industries such as steel, oil, newspapers, shipping and rail transport, it has largely been superseded by the other, more modern terms that encompass a wider range of business and commercial activity.

Mobile phone

A mobile phone (also known as a wireless phone, cell phone, or cellular telephone) is a long-range, electronic device used for mobile voice or data communication over a network of specialized base stations known as cell sites. In addition to the standard voice function of a mobile phone, telephone, current mobile phones may support many additional services, and accessories, such as SMS for text messaging, email, packet switching for access to the Internet, gaming, Bluetooth, infrared, camera with video recorder and MMS for sending and receiving photos and video, MP3 player, radio and GPS. Most current mobile phones connect to a cellular network of base stations (cell sites), which is in turn interconnected to the public switched telephone network (PSTN) (the exception is satellite phones).

According to internal memos, American Telephone & Telegraph discussed developing a wireless phone in 1915, but were afraid deployment of the technology could undermine its monopoly on wired service in the U.S.Japan's first commercial mobile phone service was launched by NTT in 1978. By November 2007, the total number of mobile phone subscriptions in the world had reached 3.3 billion, or half of the human population (although some users have multiple subscriptions, or inactive subscriptions), which also makes the mobile phone the most widely spread technology and the most common electronic device in the world.

The first mobile phone to enable internet connectivity and wireless email, the Nokia Communicator, was released in 1996, creating a new category of multi-use devices called smartphones. In 1999 the first mobile internet service was launched by NTT DoCoMo in Japan under the i-Mode service. By 2007 over 798 million people around the world accessed the internet or equivalent mobile internet services such as WAP and i-Mode at least occasionally using a mobile phone rather than a personal computer.

As of 2007, more than a billion mobile phones are sold each year, including over 100,000 smart-phones.Mobile phones send and receive radio signals with any number of cell site base stations fitted with microwave antennas. These sites are usually mounted on a tower, pole or building, located throughout populated areas, then connected to a cabled communication

Since the introduction of mobile phones, concerns (both scientific and public) have been raised about the potential health impacts from regular use. But by 2008, American mobile phones transmitted and received more text messages than phone calls. Numerous studies have reported no significant relationship between mobile phone use and health, but the effect of mobile phone usage on health continues to be an area of public concern.

For example, at the request of some of their customers, Verizon created usage controls that meter service and can switch phones off, so that children could get some sleep. There have also been attempts to limit use by persons operating moving trains or automobiles, coaches when writing to potential players on their teams, and movie theater audiences.By one measure, nearly 40% of automobile drivers aged 16 to 30 years old text while driving, and by another, 40% of teenagers said they could text blindfolded.

Barack Obama

Barack Hussein Obama II (pronounced /bəˈrɑːk hʊˈseɪn oʊˈbɑːmə/; born August 4, 1961) is the President-elect of the United States of America, and the first African American to be elected President of the United States. Obama was the junior United States Senator from Illinois in 2004 and served until his resignation on November 16, 2008, following his election to the Presidency. His term of office as the forty-fourth U.S. president is scheduled to begin on January 20, 2009.

Obama is a graduate of Columbia University and Harvard Law School, where he was the first African-American president of the Harvard Law Review. He worked as a community organizer and practiced as a civil rights attorney in Chicago before serving three terms in the Illinois Senate from 1997 to 2004. He also taught constitutional law at the University of Chicago Law School from 1992 to 2004. Following an unsuccessful bid for a seat in the U.S. House of Representatives in 2000, Obama was elected to the Senate in November 2004. Obama delivered the keynote address at the Democratic National Convention in July 2004.

As a member of the Democratic minority in the 109th Congress, Obama helped create legislation to control conventional weapons and to promote greater public accountability in the use of federal funds. He also made official trips to Eastern Europe, the Middle East, and Africa. During the 110th Congress, he helped create legislation regarding lobbying and electoral fraud, climate change, nuclear terrorism, and care for U.S. military personnel returning from combat assignments in Iraq and Afghanistan.


On February 10, 2007, Obama announced his candidacy for President of the United States in front of the Old State Capitol building in Springfield, Illinois.The choice of the announcement site was symbolic because it was also where Abraham Lincoln delivered his historic "House Divided" speech in 1858. Throughout the campaign, Obama emphasized the issues of rapidly ending the Iraq War, increasing energy independence, and providing universal health care.

On November 4, 2008, Barack Obama defeated John McCain in the general election with 365 electoral votes to McCain's 173 and became the first African American to be elected President of the United States. In his victory speech, delivered before a crowd of hundreds of thousands of his supporters in Chicago's Grant Park, Obama proclaimed that "change has come to America".

bama was sworn in as a senator on January 4, 2005. Obama was the fifth African-American Senator in U.S. history, and the third to have been popularly elected. He was the only Senate member of the Congressional Black Caucus. CQ Weekly, a nonpartisan publication, characterized him as a "loyal Democrat" based on analysis of all Senate votes in 2005–2007, and the National Journal ranked him as the "most liberal" senator based on an assessment of selected votes during 2007. In 2005 he was ranked sixteenth, and in 2006 he was ranked tenth. In 2008, Congress.org ranked him as the eleventh most powerful Senator. Obama announced on November 13, 2008 that he would resign his senate seat on November 16, 2008, before the start of the lame-duck session[clarification needed, to focus on his transition period for the presidency. This enabled him to avoid the conflict of dual roles as President-elect and Senator in the lame duck session of Congress, which no sitting member of Congress had faced since Warren Harding. His successor has not been officially assigned.

Hockey

Hockey is any of a family of sports in which two teams compete by trying to maneuver a ball, or a hard, round, rubber or heavy plastic disc called a puck, into the opponent's net or goal, using a hockey stick.Field hockey is played on gravel, natural grass, sand-based or water-based artificial turf, with a small, hard ball. The game is popular among both males and females in many parts of the world, particularly in Europe, Asia, Australia, and South Africa. In most countries, the game is played between single-sex sides, although they can be mixed-sex.

The governing body is the 116-member International Hockey Federation (FIH). Men's Field hockey has been played at each summer Olympic Games since 1908 (except 1912 and 1924), while Women's Field Hockey has been played each summer Olympic Games since 1980.Modern field hockey sticks are J-shaped and constructed of a composite of wood, glass fibre or carbon fibre (sometimes both) and have a curved hook at the playing end, a flat surface on the playing side and curved surface on the rear side. While current field hockey appeared in the mid-18th century in England, primarily in schools, it was not until the first half of the 19th century that it became firmly established. The first club was created in 1849 at Blackheath in south-east London. Field hockey is the national sport of India and Pakistan.

The Indian Hockey Federation was the Indian branch of the International Hockey Federation. In April, 2008, Kandaswamy Jothikumaran, the IHF's Secretary General, resigned after a television show accused him of corruption. K. P. S. Gill, IHF chief for 14 years, lost his position when the Indian Hockey Federation was suspended by the Indian Olympic Association (IOA) on April 28.

he Indian Olympic Association appointed a new five-member national selection committee. This panel will work in conjunction with the International Field Hockey Federation in managing hockey in India. The panel was headed by Aslam Sher Khan, a former MP and former hockey captain and includes Ashok Kumar, Ajit Pal Singh, Zafar Iqbal and Dhanraj Pillay. Aslam Sher Khan has now been replaced by Ajit Pal Singh as the chairman of the national selection committee. Aslam Sher Khan was highly displeased by this decision, though he remained as a selector.

In a 30 April 2008 interview with India Today, Khan indicated the impact of the 2007 film about the National Women's Hockey Team, Chak De India, on his future strategy by stating that he wants "to create a 'Chak De' effect" within Indian hockey. The Indian Hockey Team is the national men's field hockey team of India. It was the first non-European team to be a part of the International Hockey Federation. In 1928, the team won its first Olympic gold medal. From 1928 to 1956, the Indian men's team remained unbeaten in the Olympics, garnering six gold medals in a row. The Indian team has won a total of eight gold, one silver and two bronze medals in Olympics.

On 9 March 2008, India lost 2-0 to Britain at Santiago, Chile in the final of one of the three qualifying tournaments for the Beijing Olympics. With only the winner advancing to the 12-team event, the Indian men's team was eliminated from the Beijing Olympics competition. This is the first time that the Indian men's team will not participate in the Olympics since 1928.

The Indian Women's Hockey Team is the national women's team representing field hockey in India. Captain Suraj Lata Devi led the team to the Gold for three consecutive years: during the 2002 Commonwealth Games (the event which inspired the 2007 Bollywood hit film, Chak De India), the 2003 Afro-Asian Games, and the 2004 Hockey Asia Cup. They were referred to as the assi (Jasjeet) jaisi koi nahi or "Golden girls of hockey," after winning the 2004 Hockey Asia Cup.

On 24 April 2008, India lost 2-1 to the United States during the 2008 Women's Field Hockey Olympic Qualifier. The team was thus eliminated from the Beijing Olympics competition. On 29 April 2008, following the suspension of the Indian Hockey Federation, The Hindustan Times revealed that 16 days before leaving for the games, a report found many of the players to be unfit for international competition. The report was quoted as stating, "Eleven girls are suffering from different injuries and are under treatment and thus not fit for international competition of Olympic qualifying standards."

Tennis

Tennis is a sport played between two players (singles) or between two teams of two players each (doubles). Each player uses a strung racquet to strike a hollow rubber ball covered with felt (most of the time Optic Yellow,but can be any color or even two-tone) over a net into the opponent's court.The modern game of tennis originated in the United Kingdom in the late 19th century as "lawn tennis" and had heavy connections to the ancient game of real tennis. After its creation, tennis spread throughout the upper-class English-speaking population before spreading around the world. Tennis is an Olympic sport and is played at all levels of society at all ages. The sport can be played by anyone who can hold a racket, including people in wheelchairs. In the United States, there is a collegiate circuit organized by the National Collegiate Athletics Association.

Except for the adoption of the tiebreaker in the 1970s, the rules of tennis have changed very little since the 1890s. A recent addition to professional tennis has been the adoption of "instant replay" technology coupled with a point challenge system, which allows a player to challenge the official call of a point.Along with its millions of players, millions of people worldwide follow tennis as a spectator sport, especially the four Grand Slam tournaments (sometimes referred to as the "majors"): the Australian Open, the French Open, Wimbledon, and the US Open.

Tennis is played on a rectangular, flat surface, usually grass, clay, or a hardcourt of concrete and/or asphalt. The court is 78 feet (23.77 m) long, and its width is 27 feet (8.23 m) for singles matches and 36 ft (10.97 m) for doubles matches. Additional clear space around the court is required in order for players to reach overrun balls. A net is stretched across the full width of the court, parallel with the baselines, dividing it into two equal ends. The net is 3 feet 6 inches (1.07 m) high at the posts and 3 feet (91.4 cm) high in the center.

The design of the lawn tennis court has undergone much development. It was Major Walter Clopton Wingfield who, in 1873, designed a court approximate to the current one for his stické tennis (sphairistike). This template was modified in 1875 to the court shape that exists today; the markings homogeneous with Wingfield's design, with the hourglass shape of his court changed to a more linear framework.

The lines that delineate the width of the court are called the baseline (farthest back) and the service line (middle of the court). The short mark in the center of each baseline is referred to as either the hash mark or the center mark. The outermost lines that make up the length are called the doubles sidelines. These are the boundaries used when doubles is being played. The lines to the inside of the doubles sidelines are the singles sidelines and are used as boundaries in singles play. The area between a doubles sideline and the nearest singles sideline is called the doubles alley, which is considered playable in doubles play. The line that runs across the center of a player's side of the court is called the service line because the serve must be delivered into the area between the service line and the net on the receiving side. Despite its name, this is not where a player legally stands when making a serve.The line dividing the service line in two is called the center line or center service line. The boxes this center line creates are called the service boxes; depending on a player's position, he will have to hit the ball into one of these when serving. A ball is out only if none of it has hit the line upon its first bounce. All the lines are required to be between 1 and 2 inches (51 mm) in width. The baseline can be up to 4 inches (100 mm) wide if so desired.

A competent tennis player has eight basic shots in his or her repertoire: the serve, forehand, backhand, volley, half-volley, overhead smash, drop shot, and lob.Players use various grips during play, including the continental, eastern, and western grips. Different grips generally are used for different types of spin and shots.

Football

Football is the word given to a number of similar team sports, all of which involve (to varying degrees) kicking a ball with the foot in an attempt to score a goal. The most popular of these sports worldwide is association football, more commonly known as just "football" or "soccer". The English language word "football" is also applied to "gridiron football" (a name associated with the North American sports, especially American football and Canadian football), Australian football, Gaelic football, rugby football (rugby league and rugby union), and related games. Each of these codes (specific sets of rules, or the games defined by them) is referred to as "football".

These games involve:
* Two teams of usually between 11 and 18 players; some variations that have fewer players (five or more per team) are also popular
* a clearly defined area in which to play the game;
* scoring goals and/or points, by moving the ball to an opposing team's end of the field and either into a goal area, or over a line;
* the goal and/or line being defended by the opposing team;
* players being required to move the ball—depending on the code—by kicking, carrying and/or hand passing the ball; and
* goals and/or points resulting from players putting the ball between two goalposts.

In most codes, there are rules restricting the movement of players offside, and players scoring a goal must put the ball either under or over a crossbar between the goalposts. Other features common to several football codes include: points being mostly scored by players carrying the ball across the goal line and; players receiving a free kick after they take a mark/make a fair catch.Peoples from around the world have played games which involved kicking and/or carrying a ball, since ancient times. However, most of the modern codes of football have their origins in England.

While it is widely believed that the word "football" (or "foot ball") originated in reference to the action of the foot kicking a ball, there is a rival explanation, which has it that football originally referred to a variety of games in medieval Europe, which were played on foot. These games were usually played by peasants, as opposed to the horse-riding sports often played by aristocrats. While there is no conclusive evidence for this explanation, the word football has always implied a variety of games played on foot, not just those that involved kicking a ball. In some cases, the word football has even been applied to games which have specifically outlawed kicking the ball.

During this period, the Rugby school rules appear to have spread at least as far, perhaps further, than the other schools' codes. For example, two clubs which claim to be the world's first and/or oldest football club, in the sense of a club which is not part of a school or university, are strongholds of rugby football: the Barnes Club, said to have been founded in 1839, and Guy's Hospital Football Club, in 1843. Neither date nor the variety of football played is well-documented, but such claims nevertheless allude to the popularity of rugby before other modern codes emerged.

In 1845, three boys at Rugby school were tasked with codifying the rules then being used at the school. These were the first set of written rules (or code) for any form of football. This further assisted the spread of the Rugby game. For instance, Dublin University Football Club — founded at Trinity College, Dublin in 1854 and later famous as a bastion of the Rugby School game — is the world's oldest documented football club in any code.

The longest running football fixture is the Cordner-Eggleston Cup, contested between Melbourne Grammar School and Scotch College, Melbourne every year since 1858. It is believed by many to also be the first match of Australian rules football, although it was played under experimental rules in its first year. The first football trophy tournament was the Caledonian Challenge Cup, donated by the Royal Caledonian Society of Melbourne, played in 1861 under the Melbourne Rules. The oldest football league is a rugby football competition, the United Hospitals Challenge Cup (1874), while the oldest rugby trophy is the Rugby League Challenge Cup (1897). The South Australian Football Association (30 April 1877) is the oldest surviving Australian rules football competition. The oldest surviving soccer trophy is the Youdan Cup (1867) and the oldest national soccer competition is the English FA Cup (1871). The Football League (1888) is recognised as the longest running Association Football league.

Cricket

Cricket is a bat-and-ball team sport that originated in England, possibly as early as 1300, and is now played in more than 100 countries.[citation needed] There are several forms of cricket, at its highest level is Test cricket, in which the current world leading team is Australia, followed by One Day International cricket, whose last World Cup was also won by Australia; the tournament was televised in over 200 countries to a viewing audience estimated at more than two billion viewers.A cricket match is contested by two teams, usually of eleven players each and is played on a grass field in the centre of which is a flat strip of ground 22 yards (20 m) long called a pitch. A wicket, usually made of wood, is placed at each end of the pitch and used as a target.

The bowler, a player from the fielding team, bowls a hard leather, fist-sized, 5.5 ounces (160 g) cricket ball from the vicinity of one wicket towards the other, which is guarded by the batsman, a player from the opposing team. The ball usually bounces once before reaching the batsman. In defence of his wicket, the batsman plays the ball with a wooden cricket bat. Meanwhile, the other members of the bowler's team stand in various positions around the field as fielders, players who retrieve the ball in an effort to stop the batsman scoring runs, and if possible to get him or her out. The batsman — if he or she does not get out — may run between the wickets, exchanging ends with a second batsman (the "non-striker"), who has been stationed at the other end of the pitch. Each completed exchange of ends scores one run. Runs are also scored if the batsman hits the ball to the boundary of the playing area. The number of runs scored and the number of players out are the main factors that determine the eventual match result.

There are several variations as to how long a game of cricket can last. In professional cricket this can be anything from a match limited to 20 overs per side to a game played over 5 days. Depending on the length of the game being played, there are different rules that govern how a game is won, lost, drawn or tied.Cricket is essentially an outdoor sport, certainly at major level, and some games are played under floodlights. For example, it is played during the summer in the United Kingdom, Australia, New Zealand and South Africa, while in the West Indies, India, Pakistan, Sri Lanka and Bangladesh it is played mostly during the winter after the monsoon season.

Governance rests primarily with the International Cricket Council (ICC), based in Dubai, which organises the sport worldwide via the domestic controlling bodies of the member countries. The ICC administers both men's and women's cricket, both versions being played at international level. Although men cannot play women's cricket, the rules do not disqualify women from playing in a men's team.

The rules are in the form of a code known as The Laws of Cricket and these are maintained by the Marylebone Cricket Club (MCC), based in London, in consultation with the ICC and the domestic boards of control.The essence of the sport is that a bowler delivers the ball from his end of the pitch towards the batsman who, armed with a bat is "on strike" at the other end.The bat is made of wood and has the shape of a blade topped by a cylindrical handle. The blade must not be more than 4.25 inches (108 mm) wide and the total length of the bat not more than 38 inches (970 mm).

The ball is a hard leather-seamed spheroid with a circumference of 9 inches (230 mm). The hardness of the ball, which can be delivered at speeds of more than 90 miles per hour (140 km/h), is a matter for concern and batsmen wear protective clothing including "pads" (designed to protect the knees and shins), "batting gloves" for the hands, a helmet for the head and a "box" inside the trousers (to protect the crotch area). Some batsmen wear additional padding inside their shirts and trousers such as thigh pads, arm pads, rib protectors and shoulder pads.

ISLAM

This article contains Arabic text, written from right to left in a cursive style with some letters joined. Without proper rendering support, you may see unjoined Arabic letters written left-to-right, instead of right-to-left or other symbols instead of Arabic script.Islam's basic creed (shahadah) written on a plaque in the Great Mosque of Xi'an, China

Islam (Arabic: ar-al_islam.ogg الإسلام; al-'islām (help·info); pronounced: [ɪs.ˈlæːm][note 1]) is a monotheistic, Abrahamic religion originating with the teachings of the Islamic prophet Muhammad, a 7th century Arab religious and political figure. The word Islam means "submission", or the total surrender of oneself to God (Arabic: الله‎, Allāh). An adherent of Islam is known as a Muslim, meaning "one who submits [to God]". The word Muslim is the participle of the same verb of which Islām is the infinitive. There are between 1 billion and 1.8 billion Muslims, making Islam the second-largest religion in the world, after Christianity.

Muslims believe that God revealed the Qur'an to Muhammad, God's final prophet, through the angel Gabriel, and regard the Qur'an and the Sunnah (words and deeds of Muhammad) as the fundamental sources of Islam. They do not regard Muhammad as the founder of a new religion, but as the restorer of the original monotheistic faith of Abraham, Moses, Jesus, and other prophets. Islamic tradition holds that Jews and Christians distorted the revelations God gave to these prophets by either altering the text, introducing a false interpretation, or both.

Islam includes many religious practices. Adherents are generally required to observe the Five Pillars of Islam, which are five duties that unite Muslims into a community. In addition to the Five Pillars, Islamic law (sharia) has developed a tradition of rulings that touch on virtually all aspects of life and society. This tradition encompasses everything from practical matters like dietary laws and banking to warfare and welfare.


Islam portal

Almost all Muslims belong to one of two major denominations, the Sunni (85%) and Shi'a (15%). The schism developed in the late 7th century following disagreements over the religious and political leadership of the Muslim community. Islam is the predominant religion in much of Africa and the Middle East, as well as in major parts of Asia. Large communities are also found in China, the Balkan Peninsula in Eastern Europe and Russia. There are also large Muslim immigrant communities in other parts of the world, such as Western Europe. About 20% of Muslims live in Arab countries, 30% in the Indian subcontinent and 15.6% in Indonesia, the largest Muslim country by population.

Etymology and meaning

The word Islam is a verbal noun originating from the triliteral root s-l-m, and is derived from the Arabic verb Aslama, which means "to accept, surrender or submit." Thus, Islam means acceptance of and submission to God, and believers must demonstrate this by worshipping him, following his commands, and avoiding polytheism. The word is given a number of meanings in the Qur'an. In some verses (ayat), the quality of Islam as an internal conviction is stressed: "Whomsoever God desires to guide, He expands his breast to Islam." Other verses connect islām and dīn (usually translated as "religion"): "Today, I have perfected your religion (dīn) for you; I have completed My blessing upon you; I have approved Islam for your religion." Still others describe Islam as an action of returning to God — more than just a verbal affirmation of faith. Another technical meaning in Islamic thought is as one part of a triad of islam, imān (faith), and ihsān (excellence); where it represents acts of worship (`ibādah) and Islamic law (sharia).


Articles of faith


The Qur'an states that all Muslims must believe in God, his revelations, his angels, his messengers, and in the "Day of Judgment".Also, there are other beliefs that differ between particular sects. The Sunni concept of predestination is called divine decree, while the Shi'a version is called divine justice. Unique to the Shi'a is the doctrine of Imamah, or the political and spiritual leadership of the Imams.

Muslims believe that God revealed his final message to humanity through the Islamic prophet Muhammad via the archangel Gabriel (Jibrīl). For them, Muhammad was God's final prophet and the Qur'an is the revelations he received over more than two decades. In Islam, prophets are men selected by God to be his messengers. Muslims believe that prophets are human and not divine, though some are able to perform miracles to prove their claim. Islamic prophets are considered to be the closest to perfection of all humans, and are uniquely the recipients of divine revelation — either directly from God or through angels. The Qur'an mentions the names of numerous figures considered prophets in Islam, including Adam, Noah, Abraham, Moses and Jesus, among others. Islamic theology says that all of God's messengers since Adam preached the message of Islam — submission to the will of God. Islam is described in the Qur'an as "the primordial nature upon which God created mankind", and the Qur'an states that the proper name Muslim was given by Abraham.

As a historical phenomenon, Islam originated in Arabia in the early 7th century. Islamic texts depict Judaism and Christianity as prophetic successor traditions to the teachings of Abraham. The Qur'an calls Jews and Christians "People of the Book" (ahl al-kitāb), and distinguishes them from polytheists. Muslims believe that parts of the previously revealed scriptures, the Tawrat (Torah) and the Injil (Gospels), had become distorted — either in interpretation, in text, or both.


God


Islam's fundamental theological concept is tawhīd — the belief that there is only one god. The Arabic term for God is Allāh; most scholars believe it was derived from a contraction of the words al- (the) and ʾilāh (deity, masculine form), meaning "the god" (al-ilāh), but others trace its origin to the Aramaic Alāhā. The first of the Five Pillars of Islam, tawhīd is expressed in the shahadah (testification), which declares that there is no god but God, and that Muhammad is God's messenger. In traditional Islamic theology, God is beyond all comprehension; Muslims are not expected to visualize God but to worship and adore him as a protector. Although Muslims believe that Jesus was a prophet, they reject the Christian doctrine of the Trinity, comparing it to polytheism. In Islamic theology, Jesus was just a man and not the son of God; God is described in a chapter (sura) of the Qur'an as "…God, the One and Only; God, the Eternal, Absolute; He begetteth not, nor is He begotten; And there is none like unto Him."

Muslims consider the Qur'an to be the literal word of God; it is the central religious text of Islam. Muslims believe that the verses of the Qur'an were revealed to Muhammad by God through the angel Gabriel on many occasions between 610 and his death on June 8, 632. The Qur'an was reportedly written down by Muhammad's companions (sahabah) while he was alive, although the prime method of transmission was orally. It was compiled in the time of Abu Bakr, the first caliph, and was standardized under the administration of Uthman, the third caliph. From textual evidence Islamic studies scholars find that the Qur'an of today has not changed significantly over the years.

The Qur'an is divided into 114 suras, or chapters, which combined, contain 6,236 āyāt, or verses. The chronologically earlier suras, revealed at Mecca, are primarily concerned with ethical and spiritual topics. The later Medinan suras mostly discuss social and moral issues relevant to the Muslim community.The Qur'an is more concerned with moral guidance than legal instruction, and is considered the "sourcebook of Islamic principles and values".Muslim jurists consult the hadith, or the written record of Muhammad's life, to both supplement the Qur'an and assist with its interpretation. The science of Qur'anic commentary and exegesis is known as tafsir.

The word Qur'an means "recitation". When Muslims speak in the abstract about "the Qur'an", they usually mean the scripture as recited in Arabic rather than the printed work or any translation of it. To Muslims, the Qur'an is perfect only as revealed in the original Arabic; translations are necessarily deficient because of language differences, the fallibility of translators, and the impossibility of preserving the original's inspired style. Translations are therefore regarded only as commentaries on the Qur'an, or "interpretations of its meaning", not as the Qur'an itself.


Angels

Belief in angels is crucial to the faith of Islam. The Arabic word for angel (malak) means "messenger", like its counterparts in Hebrew (malakh) and Greek (angelos). According to the Qur'an, angels do not possess free will, and worship God in perfect obedience.Angels' duties include communicating revelations from God, glorifying God, recording every person's actions, and taking a person's soul at the time of death. They are also thought to intercede on man's behalf. The Qur'an describes angels as "messengers with wings — two, or three, or four (pairs): He [God] adds to Creation as He pleases…"


Muhammad

Muhammad (c. 570 – June 8, 632) was an Arab religious, political, and military leader who founded the religion of Islam as a historical phenomenon. Muslims view him not as the creator of a new religion, but as the restorer of the original, uncorrupted monotheistic faith of Adam, Abraham and others. In Muslim tradition, Muhammad is viewed as the last and the greatest in a series of prophets — as the man closest to perfection, the possessor of all virtues. For the last 23 years of his life, beginning at age 40, Muhammad reported receiving revelations from God. The content of these revelations, known as the Qur'an, was memorized and recorded by his companions.
The Masjid al-Nabawi ("Mosque of the Prophet") in Madina is the site of Muhammad's tomb.

During this time, Muhammad preached to the people of Mecca, imploring them to abandon polytheism. Although some converted to Islam, Muhammad and his followers were persecuted by the leading Meccan authorities. After 13 years of preaching, Muhammad and the Muslims performed the Hijra ("emigration") to the city of Medina (formerly known as Yathrib) in 622. There, with the Medinan converts (Ansar) and the Meccan migrants (Muhajirun), Muhammad established his political and religious authority. Within years, two battles had been fought against Meccan forces: the Battle of Badr in 624, which was a Muslim victory, and the Battle of Uhud in 625, which ended inconclusively. Conflict with Medinan Jewish clans who opposed the Muslims led to their exile, enslavement or death, and the Jewish enclave of Khaybar was subdued. At the same time, Meccan trade routes were cut off as Muhammad brought surrounding desert tribes under his control. By 629 Muhammad was victorious in the nearly bloodless Conquest of Mecca, and by the time of his death in 632 he ruled over the Arabian peninsula.

In Islam, the "normative" example of Muhammad's life is called the Sunnah (literally "trodden path"). This example is preserved in traditions known as hadith ("reports"), which recount his words, his actions, and his personal characteristics. The classical Muslim jurist ash-Shafi'i (d. 820) emphasized the importance of the Sunnah in Islamic law, and Muslims are encouraged to emulate Muhammad's actions in their daily lives. The Sunnah is seen as crucial to guiding interpretation of the Qur'an.


Resurrection and judgment

Belief in the "Day of Resurrection", yawm al-Qiyāmah (also known as yawm ad-dīn, "Day of Judgment" and as-sā`a, "the Last Hour") is also crucial for Muslims. They believe that the time of Qiyāmah is preordained by God but unknown to man. The trials and tribulations preceding and during the Qiyāmah are described in the Qur'an and the hadith, and also in the commentaries of Islamic scholars. The Qur'an emphasizes bodily resurrection, a break from the pre-Islamic Arabian understanding of death. It states that resurrection will be followed by the gathering of mankind, culminating in their judgment by God.

The Qur'an lists several sins that can condemn a person to hell, such as disbelief, usury and dishonesty. Muslims view paradise (jannah) as a place of joy and bliss, with Qur'anic references describing its features and the physical pleasures to come. There are also references to a greater joy — acceptance by God (ridwān). Mystical traditions in Islam place these heavenly delights in the context of an ecstatic awareness of God.


Predestination and free will

In accordance with the Sunni Islamic belief in predestination, or divine preordainment (al-qadā wa'l-qadar), God has full knowledge and control over all that occurs. This is explained in Qur'anic verses such as "Say: 'Nothing will happen to us except what Allah has decreed for us: He is our protector'…"For Muslims, everything in the world that occurs, good or evil, has been preordained and nothing can happen unless permitted by God. In Islamic theology, divine preordainment does not suggest an absence of God's indignation against evil, because any evils that do occur are thought to result in future benefits men may not be able to see. According to Muslim theologians, although events are pre-ordained, man possesses free will in that he has the faculty to choose between right and wrong, and is thus responsible for his actions. According to Islamic tradition, all that has been decreed by God is written in al-Lawh al-Mahfūz, the "Preserved Tablet".

The Shi'a understanding of free will is called "divine justice" (Adalah). This doctrine, originally developed by the Mu'tazila, stresses the importance of man's responsibility for his own actions. In contrast, the Sunni deemphasize the role of individual free will in the context of God's creation and foreknowledge of all things.


Duties and practices

Five Pillars

Rituals of the Hajj (pilgrimage) include walking seven times around the Kaaba in Mecca.

The Five Pillars of Islam (Arabic: أركان الإسلام) are five practices essential to Sunni Islam. Shi'a Muslims subscribe to different sets of pillars which substantially overlap with the Five Pillars. They are:

* The shahadah, which is the basic creed or tenet of Islam: "'ašhadu 'al-lā ilāha illā-llāhu wa 'ašhadu 'anna muħammadan rasūlu-llāh", or "I testify that there is none worthy of worship except God and I testify that Muhammad is the Messenger of God." This testament is a foundation for all other beliefs and practices in Islam. Muslims must repeat the shahadah in prayer, and non-Muslims wishing to convert to Islam are required to recite the creed.
* Salah, or ritual prayer, which must be performed five times a day. Each salah is done facing towards the Kaaba in Mecca. Salah is intended to focus the mind on God, and is seen as a personal communication with him that expresses gratitude and worship. Salah is compulsory but flexibility in the specifics is allowed depending on circumstances. In many Muslim countries, reminders called Adhan (call to prayer) are broadcast publicly from local mosques at the appropriate times. The prayers are recited in the Arabic language, and consist of verses from the Qur'an.
* Zakat, or alms-giving. This is the practice of giving based on accumulated wealth, and is obligatory for all Muslims who can afford it. A fixed portion is spent to help the poor or needy, and also to assist the spread of Islam. The zakat is considered a religious obligation (as opposed to voluntary charity) that the well-off owe to the needy because their wealth is seen as a "trust from God's bounty". The Qur'an and the hadith also suggest a Muslim give even more as an act of voluntary alms-giving (sadaqah).
* Sawm, or fasting during the month of Ramadan. Muslims must not eat or drink (among other things) from dawn to dusk during this month, and must be mindful of other sins. The fast is to encourage a feeling of nearness to God, and during it Muslims should express their gratitude for and dependence on him, atone for their past sins, and think of the needy. Sawm is not obligatory for several groups for whom it would constitute an undue burden. For others, flexibility is allowed depending on circumstances, but missed fasts usually must be made up quickly. Some Muslim groups do not fast during Ramadan, and instead have fasts different times of the year.
* The Hajj, which is the pilgrimage during the Islamic month of Dhu al-Hijjah in the city of Mecca. Every able-bodied Muslim who can afford it must make the pilgrimage to Mecca at least once in his or her lifetime. When the pilgrim is about ten kilometers from Mecca, he must dress in Ihram clothing, which consists of two white seamless sheets. Rituals of the Hajj include walking seven times around the Kaaba, touching the Black Stone, running seven times between Mount Safa and Mount Marwah, and symbolically stoning the Devil in Mina. The pilgrim, or the hajji, is honored in his or her community, although Islamic teachers say that the Hajj should be an expression of devotion to God instead of a means to gain social standing.


Law

The Sharia (literally: "the path leading to the watering place") is Islamic law formed by traditional Islamic scholarship, which most Muslim groups adhere to. In Islam, Sharia is the expression of the divine will, and "constitutes a system of duties that are incumbent upon a Muslim by virtue of his religious belief".

Islamic law covers all aspects of life, from matters of state, like governance and foreign relations, to issues of daily living. The Qur'an defines hudud as the punishments for five specific crimes: unlawful intercourse, false accusation of unlawful intercourse, consumption of alcohol, theft, and highway robbery. The Qur'an and Sunnah also contain laws of inheritance, marriage, and restitution for injuries and murder, as well as rules for fasting, charity, and prayer. However, these prescriptions and prohibitions may be broad, so their application in practice varies. Islamic scholars (known as ulema) have elaborated systems of law on the basis of these rules and their interpretations.

Fiqh, or "jurisprudence", is defined as the knowledge of the practical rules of the religion. The method Islamic jurists use to derive rulings is known as usul al-fiqh ("legal theory", or "principles of jurisprudence"). According to Islamic legal theory, law has four fundamental roots, which are given precedence in this order: the Qur'an, the Sunnah (actions and sayings of Muhammad), the consensus of the Muslim jurists (ijma), and analogical reasoning (qiyas). For early Islamic jurists, theory was less important than pragmatic application of the law. In the 9th century, the jurist ash-Shafi'i provided a theoretical basis for Islamic law by codifying the principles of jurisprudence (including the four fundamental roots) in his book ar-Risālah.


Religion and state

Mainstream Islamic law does not distinguish between "matters of church" and "matters of state"; the ulema function as both jurists and theologians. In practice, Islamic rulers frequently bypassed the Sharia courts with a parallel system of so-called "Grievance courts" over which they had sole control. As the Muslim world came into contact with Western secular ideals, Muslim societies responded in different ways. Turkey has been governed as a secular state ever since the reforms of Mustafa Kemal Atatürk. In contrast, the 1979 Iranian Revolution replaced a mostly secular regime with an Islamic republic led by the Ayatollah Khomeini.


Etiquette and diet

Many practices fall in the category of adab, or Islamic etiquette. This includes greeting others with "as-salamu `alaykum" ("peace be unto you"), saying bismillah ("in the name of God") before meals, and using only the right hand for eating and drinking. Islamic hygienic practices mainly fall into the category of personal cleanliness and health, such as the circumcision of male offspring. Islamic burial rituals include saying the Salat al-Janazah ("funeral prayer") over the bathed and enshrouded dead body, and burying it in a grave. Muslims, like Jews, are restricted in their diet, and prohibited foods include pig products, blood, carrion, and alcohol. All meat must come from a herbivorous animal slaughtered in the name of God by a Muslim, Jew, or Christian, with the exception of game that one has hunted or fished for oneself. Food permissible for Muslims is known as halal food.


Jihad

Jihad means "to strive or struggle" (in the way of God) and is considered the "sixth pillar of Islam" by a minority of Sunni Muslim authorities. Jihad, in its broadest sense, is classically defined as "exerting one's utmost power, efforts, endeavors, or ability in contending with an object of disapprobation." Depending on the object being a visible enemy, the devil, and aspects of one's own self, different categories of Jihad are defined. Jihad when used without any qualifier is understood in its military aspect. Jihad also refers to one's striving to attain religious and moral perfection.Some Muslim authorities, especially among the Shi'a and Sufis, distinguish between the "greater jihad", which pertains to spiritual self-perfection, and the "lesser jihad", defined as warfare.

Within Islamic jurisprudence, jihad is usually taken to mean military exertion against non-Muslim combatants in the defense or expansion of the Islamic state, the ultimate purpose of which is to universalize Islam. Jihad, the only form of warfare permissible in Islamic law, may be declared against apostates, rebels, highway robbers, violent groups, unIslamic leaders or states which refuse to submit to the authority of Islam. Most Muslims today interpret Jihad as only a defensive form of warfare: the external Jihad includes a struggle to make the Islamic societies conform to the Islamic norms of justice.

Under most circumstances and for most Muslims, jihad is a collective duty (fard kifaya): its performance by some individuals exempts the others. Only for those vested with authority, especially the sovereign (imam), does jihad become an individual duty. For the rest of the populace, this happens only in the case of a general mobilization.For most Shias, offensive jihad can only be declared by a divinely appointed leader of the Muslim community, and as such is suspended since Muhammad al-Mahdi's occultation in 868 AD.
History


Islam's historical development resulted in major political, economic, and military effects inside and outside the Islamic world. Within a century of Muhammad's first recitations of the Qur'an, an Islamic empire stretched from the Atlantic Ocean in the west to Central Asia in the east. This new polity soon broke into civil war, and successor states fought each other and outside forces. However, Islam continued to spread into regions like Africa, the Indian subcontinent, and Southeast Asia. The Islamic civilization was one of the most advanced in the world during the Middle Ages, but was surpassed by Europe with the economic and military growth of the West. During the 18th and 19th centuries, Islamic dynasties such as the Ottomans and Mughals fell under the sway of European imperial powers. In the 20th century new religious and political movements and newfound wealth in the Islamic world led to both rebirth and conflict.


Rise of the caliphate and Islamic civil war (632–750)

Muhammad began preaching Islam at Mecca before migrating to Medina, from where he united the tribes of Arabia into a singular Arab Muslim religious polity. With Muhammad's death in 632, disagreement broke out over who would succeed him as leader of the Muslim community. Umar ibn al-Khattab, a prominent companion of Muhammad, nominated Abu Bakr, who was Muhammad's intimate friend and collaborator. Others added their support and Abu Bakr was made the first caliph. This choice was disputed by some of Muhammad's companions, who held that Ali ibn Abi Talib, his cousin and son-in-law, had been designated his successor. Abu Bakr's immediate task was to avenge a recent defeat by Byzantine (or Eastern Roman Empire) forces, although he first had to put down a rebellion by Arab tribes in an episode known as the Ridda wars, or "Wars of Apostasy".
The territory of the Caliphate in 750

His death in 634 resulted in the succession of Umar as the caliph, followed by Uthman ibn al-Affan and Ali ibn Abi Talib. These four are known as al-khulafā' ar-rāshidūn ("Rightly Guided Caliphs"). Under them, the territory under Muslim rule expanded deeply into Persian and Byzantine territories.

When Umar was assassinated in 644, the election of Uthman as successor was met with increasing opposition. In 656, Uthman was also killed, and Ali assumed the position of caliph. After fighting off opposition in the first civil war (the "First Fitna"), Ali was assassinated by Kharijites in 661. Following this, Mu'awiyah, who held the governorship of the Levant at the time, seized power and began the Umayyad dynasty.

These disputes over religious and political leadership would give rise to schism in the Muslim community. The majority accepted the legitimacy of the three rulers prior to Ali, and became known as Sunnis. A minority disagreed, and believed that Ali was the only rightful successor; they became known as the Shi'a.After Mu'awiyah's death in 680, conflict over succession broke out again in a civil war known as the "Second Fitna". Afterward, the Umayyad dynasty prevailed for seventy years, and was able to conquer the Maghrib and Al-Andalus (the Iberian Peninsula, former Visigothic Hispania) and the Narbonnese Gaul in the west as well as expand Muslim territory into Sindh and the fringes of Central Asia. While the Muslim-Arab elite engaged in conquest, some devout Muslims began to question the piety of indulgence in a worldly life, emphasizing, rather, poverty, humility, and avoidance of sin based on renunciation of bodily desires. Devout Muslim ascetic exemplars such as Hasan al-Basri would inspire a movement that would evolve into Sufism.

For the Umayyad aristocracy, Islam was viewed as a religion for Arabs only; the economy of the Umayyad empire was based on the assumption that a majority of non-Muslims (Dhimmis) would pay taxes to the minority of Muslim Arabs. A non-Arab who wanted to convert to Islam was supposed to first become a client of an Arab tribe. Even after conversion, these new Muslims (mawali) did not achieve social and economic equality with the Arabs. The descendants of Muhammad's uncle Abbas ibn Abd al-Muttalib rallied discontented mawali, poor Arabs, and some Shi'a against the Umayyads and overthrew them with the help of their propagandist and general Abu Muslim, inaugurating the Abbasid dynasty in 750. Under the Abbasids, Islamic civilization flourished in the "Islamic Golden Age", with its capital at the cosmopolitan city of Baghdad.


Golden Age (750–1258)

By the late 9th century, the Abbasid caliphate began to fracture as various regions gained increasing levels of autonomy. Across North Africa, Persia, and Central Asia emirates formed as provinces broke away. The monolithic Arab empire gave way to a more religiously homogenized Muslim world where the Shia Fatimids contested even the religious authority of the caliphate. By 1055 the Seljuq Turks had eliminated the Abbasids as a military power, nevertheless they continued to respect the caliph's titular authority. During this time expansion of the Muslim world continued, by both conquest and peaceful proselytism even as both Islam and Muslim trade networks were extending into sub-Saharan West Africa, Central Asia, Volga Bulgaria and the Malay archipelago.

The Golden Age saw new legal, philosophical, and religious developments. The major hadith collections were compiled and the four modern Sunni Madh'habs were established. Islamic law was advanced greatly by the efforts of the early 9th century jurist al-Shafi'i; he codified a method to establish the reliability of hadith, a topic which had been a locus of dispute among Islamic scholars. Philosophers Ibn Sina (Avicenna) and Al-Farabi sought to incorporate Greek principles into Islamic theology, while others like the 11th century theologian Abu Hamid al-Ghazzali argued against them and ultimately prevailed. Finally, Sufism and Shi'ism both underwent major changes in the 9th century. Sufism became a full-fledged movement that had moved towards mysticism and away from its ascetic roots, while Shi'ism split due to disagreements over the succession of Imams.

The spread of the Islamic dominion induced hostility among medieval ecclesiastical Christian authors who saw Islam as an adversary in the light of the large numbers of new Muslim converts. This opposition resulted in polemical treatises which depicted Islam as the religion of the antichrist and of Muslims as libidinous and subhuman. In the medieval period, a few Arab philosophers like the poet Al-Ma'arri adopted a critical approach to Islam, and the Jewish philosopher Maimonides contrasted Islamic views of morality to Jewish views that he himself elaborated.


Crusades, Reconquista and Mongol invasion

Starting in the 9th century, Muslim conquests in the West began to be reversed. The Reconquista was launched against Muslim principalities in Iberia, and Muslim Italian possessions were lost to the Normans. From the 11th century onwards alliances of European Christian kingdoms mobilized to launch a series of wars known as the Crusades, bringing the Muslim world into conflict with Christendom. Initially successful in their goal of taking the Holy land, and establishing the Crusader states, Crusader gains in the Holy Land were later reversed by subsequent Muslim generals such as Saladin; who recaptured Jerusalem during the Second Crusade. In the east the Mongol Empire put an end to the Abbassid dynasty at the Battle of Baghdad in 1258, as they overran the Muslim lands in a series of invasions. Meanwhile in Egypt, the slave-soldier Mamluks took control in an uprising in 1250 and in alliance with the Golden Horde halted the Mongol armies at the Battle of Ain Jalut. But Mongol rule extended across the breadth of almost all Muslim lands in Asia and Islam was temporarily replaced by Buddhism as the official religion of the land. Over the next century the Mongol Khanates converted to Islam and this religious and cultural absorption ushered in a new age of Mongol-Islamic synthesis that shaped the further spread of Islam in central Asia and the Indian subcontinent.

The Black Death ravaged much of the Islamic world in the mid-14th century. It is probable that the Mongols and merchant caravans making use of the opportunities of free passage offered by the Pax Mongolica inadvertently brought the plague from Central Asia to the Middle East and Europe. Plague epidemics kept returning to the Islamic world up to the 19th century.


Turkish, Iranian and Indian empires (1030–1918)

The Seljuk Turks conquered Abbassid lands and adopted Islam and become the de facto rulers of the caliphate. They captured Anatolia by defeating the Byzantines at the Battle of Manzikert, thereby precipitating the call for Crusades. They however fell apart rapidly in the second half of the 12th century giving rise to various semi-autonomous Turkic dynasties. In the 13th and 14th centuries the Ottoman empire (named after Osman I) emerged from among these "Ghazi emirates" and established itself after a string of conquests that included the Balkans, parts of Greece, and western Anatolia. In 1453 under Mehmed II the Ottomans laid siege to Constantinople, the capital of Byzantium, which succumbed shortly thereafter, having been overwhelmed by a far greater number of Ottoman troops and to a lesser extent, cannonry.

Beginning in the 13th century, Sufism underwent a transformation, largely as a result of the efforts of al-Ghazzali to legitimize and reorganize the movement. He developed the model of the Sufi order — a community of spiritual teachers and students. Also of importance to Sufism was the creation of the Masnavi, a collection of mystical poetry by the 13th century Persian poet Rumi. The Masnavi had a profound influence on the development of Sufi religious thought; to many Sufis it is second in importance only to the Qur'an.

In the early 16th century, the Shi'i Safavid dynasty assumed control in Persia and established Shi'a Islam as an official religion there, and despite periodic setbacks, the Safavids remained powerful for two centuries. Meanwhile, Mamluk Egypt fell to the Ottomans in 1517, who then launched a European campaign which reached as far as the gates of Vienna in 1529. After the invasion of Persia, and sack of Baghdad by the Mongols in 1258, Delhi became the most important cultural centre of the Muslim east. Many Islamic dynasties ruled parts of the Indian subcontinent starting from the 12th century. The prominent ones include the Delhi Sultanate (1206–1526) and the Mughal empire (1526–1857). These empires helped in the spread of Islam in South Asia, but by the early-18th century the Maratha empire became the pre-eminent power in the north of India. By the mid-18th century the British empire had formally ended the Mughal dynasty,, and at the end of the 18th century overthrew the Muslim-ruled Kingdom of Mysore. In the 18th century the Wahhabi movement took hold in Saudi Arabia. Founded by the preacher Ibn Abd al-Wahhab, Wahhabism is a fundamentalist ideology that condemns practices like Sufism and the veneration of saints as un-Islamic.

By the 17th and 18th centuries, despite attempts at modernization, the Ottoman empire had begun to feel threatened by European economic and military advantages. In the 19th century, the rise of nationalism resulted in Greece declaring and winning independence in 1829, with several Balkan states following suit after the Ottomans suffered defeat in the Russo-Turkish War of 1877–1878. The Ottoman era came to a close at the end of World War I and the Caliphate was abolished in 1924.


In the 19th century, the Salafi, Deobandi and Barelwi movements were initiated.

Modern times (1918–present)

By the early years of the 20th century, most of the Muslim world outside the Ottoman empire had been absorbed into the empires of non-Islamic European powers. After World War I losses, nearly all of the Ottoman empire was also parceled out as European protectorates or spheres of influence. In the course of the 20th century, most of these European-ruled territories became independent, and new issues such as oil wealth and relations with the State of Israel have assumed prominence. During this time, many Muslims migrated, as indentured servants, from mostly India and Indonesia to the Caribbean, forming the largest Muslim populations by percentage in the Americas.Additionally, the resulting urbanization and increase in trade in Africa brought Muslims to settle in new areas and spread their faith. As a result, Islam in sub-Saharan Africa likely doubled between 1869 and 1914. The Organization of the Islamic Conference (OIC), consisting of Muslim countries, was formally established in September 1969 after the burning of the Al-Aqsa Mosque in Jerusalem.

The 20th century saw the creation of many new Islamic "revivalist" movements. Groups such as the Muslim Brotherhood in Egypt and Jamaat-e-Islami in Pakistan advocate a totalistic and theocratic alternative to secular political ideologies. Sometimes called Islamist, they see Western cultural values as a threat, and promote Islam as a comprehensive solution to every public and private question of importance. In countries like Iran and Afghanistan (under the Taliban), revolutionary movements replaced secular regimes with Islamist states, while transnational groups like Osama bin Laden's al-Qaeda engage in terrorism to further their goals. In contrast, Liberal Islam is a movement that attempts to reconcile religious tradition with modern norms of secular governance and human rights. Its supporters say that there are multiple ways to read Islam's sacred texts, and stress the need to leave room for "independent thought on religious matters".

Modern critique of Islam includes accusations that Islam is intolerant of criticism and that Islamic law is too hard on apostates. Critics like Ibn Warraq question the morality of the Qu'ran, saying that its contents justify the mistreatment of women and encourage antisemitic remarks by Muslim theologians. Such claims are disputed by Muslim writers like Fazlur Rahman Malik, Syed Ameer Ali, Ahmed Deedat, and Yusuf Estes. Others like Daniel Pipes and Martin Kramer focus more on criticizing the spread of Islamic fundamentalism, a danger they feel has been ignored. Montgomery Watt and Norman Daniel dismiss many of the criticisms as the product of old myths and polemics. The rise of Islamophobia, according to Carl Ernst, had contributed to the negative views about Islam and Muslims in the West.

Pascal Bruckner and Paul Berman on the other hand have entered the "Islam in Europe" debate. Berman identifies a "reactionary turn in the intellectual world" represented by Western scholars who idealize Islam.
Community


Demographics

Muslim percentage of population by country

Commonly cited estimates of the Muslim population in 2007 range from 1 billion to 1.8 billion. Approximately 85% are Sunni and 15% are Shi'a, with a small minority belonging to other sects. Some 30–40 countries are Muslim-majority, and Arabs account for around 20% of all Muslims worldwide. South Asia and Southeast Asia contain the most populous Muslim countries, with Indonesia, India, Pakistan, and Bangladesh having more than 100 million adherents each.According to U.S. government figures, in 2006 there were 20 million Muslims in China. In the Middle East, the non-Arab countries of Turkey and Iran are the largest Muslim-majority countries; in Africa, Egypt and Nigeria have the most populous Muslim communities. Islam is the second largest religion after Christianity in many European countries.


Mosques

A mosque is a place of worship for Muslims, who often refer to it by its Arabic name, masjid. The word mosque in English refers to all types of buildings dedicated to Islamic worship, although there is a distinction in Arabic between the smaller, privately owned mosque and the larger, "collective" mosque (masjid jāmi`). Although the primary purpose of the mosque is to serve as a place of prayer, it is also important to the Muslim community as a place to meet and study. Modern mosques have evolved greatly from the early designs of the 7th century, and contain a variety of architectural elements such as minarets.


Family life

The basic unit of Islamic society is the family, and Islam defines the obligations and legal rights of family members. The father is seen as financially responsible for his family, and is obliged to cater for their well-being. The division of inheritance is specified in the Qur'an, which states that most of it is to pass to the immediate family, while a portion is set aside for the payment of debts and the making of bequests. The woman's share of inheritance is generally half of that of a man with the same rights of succession. Marriage in Islam is a civil contract which consists of an offer and acceptance between two qualified parties in the presence of two witnesses. The groom is required to pay a bridal gift (mahr) to the bride, as stipulated in the contract.

A man may have up to four wives if he believes he can treat them equally, while a woman may have only one husband. In most Muslim countries, the process of divorce in Islam is known as talaq, which the husband initiates by pronouncing the word "divorce".Scholars disagree whether Islamic holy texts justify traditional Islamic practices such as veiling and seclusion (purdah). Starting in the 20th century, Muslim social reformers argued against these and other practices such as polygamy, with varying success. At the same time, many Muslim women have attempted to reconcile tradition with modernity by combining an active life with outward modesty. Certain Islamist groups like the Taliban have sought to continue traditional law as applied to women.


Calendar

The formal beginning of the Muslim era was chosen to be the Hijra in 622 CE, which was an important turning point in Muhammad's fortunes. The assignment of this year as the year 1 AH (Anno Hegirae) in the Islamic calendar was reportedly made by Caliph Umar. It is a lunar calendar, with nineteen ordinary years of 354 days and eleven leap years of 355 days in a thirty-year cycle. Islamic dates cannot be converted to CE/AD dates simply by adding 622 years: allowance must also be made for the fact that each Hijri century corresponds to only 97 years in the Christian calendar.

The year 1428 AH coincides almost completely with 2007 CE.

Islamic holy days fall on fixed dates of the lunar calendar, which means that they occur in different seasons in different years in the Gregorian calendar. The most important Islamic festivals are Eid al-Fitr (Arabic: عيد الفطر) on the 1st of Shawwal, marking the end of the fasting month Ramadan, and Eid al-Adha (Arabic: عيد الأضحى) on the 10th of Dhu al-Hijjah, coinciding with the pilgrimage to Mecca.

According to Islamic doctrine, Islam was the primordial religion of mankind, professed by Adam. At some point, a religious split occurred, and God began sending prophets to bring his revelations to the people. In this view, Abraham, Moses, Hebrew prophets, and Jesus were all Prophets in Islam, but their message and the texts of the Torah and the Gospels were corrupted by Jews and Christians. Similarly, children of non-Muslim families are born Muslims, but are converted to another faith by their parents. The idea of Islamic supremacy is encapsulated in the formula "Islam is exalted and nothing is exalted above it." Pursuant to this principle, Muslim women may not marry non-Muslim men, defamation of Islam is prohibited, and the testimony of a non-Muslim is inadmissible against a Muslim.

Islamic law divides non-Muslims into several categories, depending on their relation with the Islamic state. Christians and Jews who live under Islamic rule are known as dhimmis ("protected peoples"). According to this pact, the personal safety and security of property of the dhimmis were guaranteed in return for paying tribute (jizya) to the Islamic state and acknowledging Muslim supremacy. Historically, dhimmis enjoyed a measure of communal autonomy under their own religious leaders, but were subject to legal, social and religious restrictions meant to highlight their inferiority. The status was extended to other groups like Zoroastrians and Hindus, but not to atheists or agnostics.Those who live in non-Muslim lands (dar al-harb) are known as harbis, and upon entering into an alliance with the Muslim state become known as ahl al-ahd. Those who receive a guarantee of safety while residing temporarily in Muslim lands are known as ahl al-amān. Their legal position is similar to that of the dhimmi except that they are not required to pay the jizya. The people of armistice (ahl al-hudna) are those who live outside of Muslim territory and agree to refrain from attacking the Muslims. Apostasy is prohibited, and is punishable by death.


The Alevi, Yazidi, Druze, Ahmadiyya, Bábí, Bahá'í, Berghouata and Ha-Mim movements either emerged out of Islam or came to share certain beliefs with Islam. Some consider themselves separate while others still sects of Islam though controversial in certain beliefs with mainstream Muslims. Sikhism, founded by Guru Nanak in late 15th century Punjab, incorporates aspects of both Islam and Hinduism.


Denominations

Islam consists of a number of religious denominations that are essentially similar in belief but which have significant theological and legal differences. The primary division is between the Sunni and the Shi'a, with Sufism generally considered to be a mystical inflection of Islam rather than a distinct school. According to most sources, approximately 85% of the world's Muslims are Sunni and approximately 15% are Shi'a, with a small minority who are members of other Islamic sects.


Sunni

Sunni Muslims are the largest group in Islam. In Arabic, as-Sunnah literally means "principle" or "path". The Sunnah (the example of Muhammad's life) as recorded in the Qur'an and the hadith is the main pillar of Sunni doctrine. Sunnis believe that the first four caliphs were the rightful successors to Muhammad; since God did not specify any particular leaders to succeed him, those leaders had to be elected. Sunnis recognize four major legal traditions, or madhhabs: Hanafi, Maliki, Shafi'i, and Hanbali. All four accept the validity of the others and a Muslim might choose any one that he or she finds agreeable, but other Islamic sects are believed to have departed from the majority by introducing innovations (bidah). There are also several orthodox theological or philosophical traditions within Sunnism. For example, the recent Salafi movement sees itself as restorationist and claims to derive its teachings from the original sources of Islam.


Shi'a

The Shi'a, who constitute the second-largest branch of Islam, believe in the political and religious leadership of Imams from the progeny of Ali ibn Abi Talib, who according to most Shi'a are in a state of ismah, meaning infallibility. They believe that Ali ibn Abi Talib, as the cousin and son-in-law of Muhammad, was his rightful successor, and they call him the first Imam (leader), rejecting the legitimacy of the previous Muslim caliphs. To most Shi'a, an Imam rules by right of divine appointment and holds "absolute spiritual authority" among Muslims, having final say in matters of doctrine and revelation. Shi'a Islam has several branches, the largest of which is the Twelvers (iṯnāʿašariyya) which the label Shi'a generally refers to. Although the Twelver Shi'a share many core practices with the Sunni, the two branches disagree over the proper importance and validity of specific collections of hadith. The Twelver Shi'a follow a legal tradition called Ja'fari jurisprudence. Other smaller groups include the Ismaili and Zaidi, who differ from Twelvers in both their line of successors and theological beliefs.


Sufism

Not strictly a denomination, Sufism is a mystical-ascetic form of Islam. By focusing on the more spiritual aspects of religion, Sufis strive to obtain direct experience of God by making use of "intuitive and emotional faculties" that one must be trained to use. Sufism and Islamic law are usually considered to be complementary, although Sufism has been criticized by some Muslims for being an unjustified religious innovation. Most Sufi orders, or tariqas, can be classified as either Sunni or Shi'a.


Others

The Kharijites are a sect that dates back to the early days of Islam. The only surviving branch of the Kharijites is Ibadism. Unlike most Kharijite groups, Ibadism does not regard sinful Muslims as unbelievers. The Imamate is an important topic in Ibadi legal literature, which stipulates that the leader should be chosen solely on the basis of his knowledge and piety, and is to be deposed if he acts unjustly. Most Ibadi Muslims live in Oman.
