U.S. Consumer Product Safety Commission
The United States Consumer Product Safety Commission is an independent agency of the United States government. The CPSC seeks to promote the safety of consumer products by addressing "unreasonable risks" of injury. In part due to its small size, the CPSC attempts to coordinate with outside parties—including companies and consumer advocates—to leverage resources and expertise to achieve outcomes that advance consumer safety; the agency was created in 1972 through the Consumer Product Safety Act. The agency reports to the President; the CPSC has five commissioners, who are nominated by the president and confirmed by the Senate for staggered seven-year terms. The Commission was run by three commissioners or fewer. Since 2009, the agency has been led by five commissioners, one of whom serves as chairman; the commissioners set policy for the CPSC. The CPSC is headquartered in Maryland; the commissioners of the CPSC are appointed by the U. S. president and with the consent of the U. S. Senate; as with some other U.
S. federal independent agencies, commissioners are selected as members of political parties. Although the president is entitled by statute to select the chairman, no more than three commissioners may belong to the same party. Thus, the president is expected to consult with members of the opposite party in the Senate to select members of the commission from the opposite party; the commissioners vote on selecting the vice chairman, who becomes acting chairman if the chairman’s term ends upon resignation or expiration. The CPSC regulates the manufacture and sale of more than 15,000 different consumer products, from cribs to all-terrain vehicles. Products excluded from the CPSC's jurisdiction include those named by law as under the jurisdiction of other federal agencies; the CPSC fulfills its mission by banning dangerous consumer products, establishing safety requirements for other consumer products, issuing recalls of products on the market, researching potential hazards associated with consumer products.
The CPSC makes rules about consumer products when it identifies a consumer product hazard, not addressed by an industry voluntary consensus standard, or when Congress directs it to do so. Its rules can specify basic design requirements, or they can amount to product bans, as in the case of small high-powered magnets, which the CPSC attempted to ban. For certain infant products, the CPSC regulates when voluntary standards exist; the CPSC is required to follow a scientific process to develop mandatory rules. Failing to do so can justify the revocation of a rule, as was the case in a Tenth Circuit decision vacating the CPSC's ban on small high-powered magnets; the CPSC learns about unsafe products in several ways. The agency maintains a consumer hotline through which consumers may report concerns about unsafe products or injuries associated with products. Product safety concerns may be submitted through SaferProducts.gov The agency operates the National Electronic Injury Surveillance System, a probability sample of about 100 hospitals with 24-hour emergency rooms.
NEISS collects data on consumer product related injuries treated in ERs and can be used to generate national estimates. The agency works with and shares information with other governments, both in the U. S. and with international counterparts. The CPSC works on a variety of publicity campaigns to raise awareness of safety. For example, the CPSC blows up mannequins to demonstrate the dangers of improper use of fireworks. Since February 2015, the average civil penalty has been $2.9 million. In April 2018, Polaris Industries agreed to pay a record $27.25 million civil penalty for failing to report defective off-road vehicles. On November 2, 2007, the Washington Post reported that between 2002 and the date of their report, former chairman Hal Stratton and current commissioner and former acting chairman Nancy Nord had taken more than 30 trips paid for by manufacturing groups or lobbyists representing industries that are under the supervision of the agency. According to the Post, the groups paid for over $60,000 travel and related expenses during this time.
In 1972 when the agency was created, it had 786 staff members. By 2008 it had 401 employees on a budget of $43 million, but the Consumer Product Safety Improvement Act passed in 2008 increases funding $136.4 million in 2014 with full-time employees to at least 500 by 2013. 2007 has been called the "Year of the Recall" in the United States, the CPSC alone obtained 473 voluntary recalls in 2007, a record. This notably included many incidents with lead in other children's products; these issues led to the legislative interest in the reform of the agency, the final result of these efforts was the passage of the Consumer Product Safety Improvement Act in 2008. The bill increased funding and staffing for the CPSC, placed stricter limits on lead levels in children's products
The automotive industry is a wide range of companies and organizations involved in the design, manufacturing and selling of motor vehicles. It is one of the world's largest economic sectors by revenue; the automotive industry does not include industries dedicated to the maintenance of automobiles following delivery to the end-user, such as automobile repair shops and motor fuel filling stations. The word automotive is from the Greek autos, Latin motivus to refer to any form of self-powered vehicle; this term, as proposed by Elmer Sperry, first came into use with reference to automobiles in 1898. The automotive industry began in the 1860s with hundreds of manufacturers that pioneered the horseless carriage. For many decades, the United States led the world in total automobile production. In 1929, before the Great Depression, the world had 32,028,500 automobiles in use, the U. S. automobile industry produced over 90% of them. At that time the U. S. had one car per 4.87 persons. After World War II, the U.
S. produced about 75 percent of world's auto production. In 1980, the U. S. was overtaken by Japan and became world's leader again in 1994. In 2006, Japan narrowly passed the U. S. in production and held this rank until 2009, when China took the top spot with 13.8 million units. With 19.3 million units manufactured in 2012, China doubled the U. S. production, with 10.3 million units, while Japan was in third place with 9.9 million units. From 1970 over 1998 to 2012, the number of automobile models in the U. S. has grown exponentially. Safety is a state that implies to be protected from any risk, damage or cause of injury. In the automotive industry, safety means that users, operators or manufacturers do not face any risk or danger coming from the motor vehicle or its spare parts. Safety for the automobiles themselves, implies that there is no risk of damage. Safety in the automotive industry is important and therefore regulated. Automobiles and other motor vehicles have to comply with a certain number of norms and regulations, whether local or international, in order to be accepted on the market.
The standard ISO 26262, is considered as one of the best practice framework for achieving automotive functional safety. In case of safety issues, product defect or faulty procedure during the manufacturing of the motor vehicle, the maker can request to return either a batch or the entire production run; this procedure is called product recall. Product recalls happen in every industry and can be production-related or stem from the raw material. Product and operation tests and inspections at different stages of the value chain are made to avoid these product recalls by ensuring end-user security and safety and compliance with the automotive industry requirements. However, the automotive industry is still concerned about product recalls, which cause considerable financial consequences. Around the world, there were about 806 million cars and light trucks on the road in 2007, consuming over 980 billion litres of gasoline and diesel fuel yearly; the automobile is a primary mode of transportation for many developed economies.
The Detroit branch of Boston Consulting Group predicts that, by 2014, one-third of world demand will be in the four BRIC markets. Meanwhile, in the developed countries, the automotive industry has slowed down, it is expected that this trend will continue as the younger generations of people no longer want to own a car anymore, prefer other modes of transport. Other powerful automotive markets are Iran and Indonesia. Emerging auto markets buy more cars than established markets. According to a J. D. Power study, emerging markets accounted for 51 percent of the global light-vehicle sales in 2010; the study, performed in 2010 expected this trend to accelerate. However, more recent reports confirmed the opposite. In the United States, vehicle sales peaked in 2000, at 17.8 million units. The OICA counts over 50 countries which assemble, manufacture or disseminate automobiles. Of that figure, only 13, boldfaced in the list below, possess the capability to design automobiles from the ground up; this is a list of the 15 largest manufacturers by production in 2016.
It is common for automobile manufacturers to hold stakes in other automobile manufacturers. These ownerships can be explored under the detail for the individual companies. Notable current relationships include: Daimler AG holds a 10.0% stake in KAMAZ. Daimler AG holds an 89.29% stake in Mitsubishi Fuso Truck and Bus Corporation. Daimler AG holds a 3.1% in the Renault-Nissan Alliance. Daimler AG holds a 12% stake in Beijing Automotive Group, Daimler AG holds an 85% stake in Master Motors. Dongfeng Motor holds a 12.23% stake and a 19.94% exercisable voting rights in PSA Groupe. FAW Group owns 49% of Haima Automobile. FCA holds a 10% stake in Ferrari. FCA holds a 67% stake in Fiat Automobili Srbija. FCA holds 37.8% of Tofaş with another 37.8% owned by Koç Holding. Fiat Automobili Srbija owns a 54% stake in Zastava Trucks. Fiat Industrial owns a 46% stake in Zastava Trucks. Fujian Motors Group holds a 15% stake in King Long. FMG, Beijing Automotive Group, China Motor, Daimler has a joint venture called Fujian Benz.
FMG, China Motor, Mitsubishi Motors has a joint venture called Soueast, FMG holds a 50% stake, both China Motor and Mitsubishi Motors holds an equal 25% stake. Geely Automobile holds a 23% stake in The London Taxi Company. Geely Automobile holds a 49.9% stake in PROTON Holdings and a 51% stake in Lotus Cars. Geely Holding Group holds a 9.69% stake in Daimle
Food and Drug Administration
The Food and Drug Administration is a federal agency of the United States Department of Health and Human Services, one of the United States federal executive departments. The FDA is responsible for protecting and promoting public health through the control and supervision of food safety, tobacco products, dietary supplements and over-the-counter pharmaceutical drugs, biopharmaceuticals, blood transfusions, medical devices, electromagnetic radiation emitting devices, animal foods & feed and veterinary products; as of 2017, 3/4th of the FDA budget is paid by people who consume pharmaceutical products, due to the Prescription Drug User Fee Act. The FDA was empowered by the United States Congress to enforce the Federal Food and Cosmetic Act, which serves as the primary focus for the Agency; these include regulating lasers, cellular phones and control of disease on products ranging from certain household pets to sperm donation for assisted reproduction. The FDA is led by the Commissioner of Food and Drugs, appointed by the President with the advice and consent of the Senate.
The Commissioner reports to the Secretary of Human Services. Scott Gottlieb, M. D. is the current commissioner, who took over in May 2017. The FDA has its headquarters in Maryland; the agency has 223 field offices and 13 laboratories located throughout the 50 states, the United States Virgin Islands, Puerto Rico. In 2008, the FDA began to post employees to foreign countries, including China, Costa Rica, Chile and the United Kingdom. In recent years, the agency began undertaking a large-scale effort to consolidate its 25 operations in the Washington metropolitan area, moving from its main headquarters in Rockville and several fragmented office buildings to the former site of the Naval Ordnance Laboratory in the White Oak area of Silver Spring, Maryland; the site was renamed from the White Oak Naval Surface Warfare Center to the Federal Research Center at White Oak. The first building, the Life Sciences Laboratory, was dedicated and opened with 104 employees on the campus in December 2003. Only one original building from the naval facility was kept.
All other buildings are new construction. The project is slated to be completed by 2021, assuming future Congressional funding While most of the Centers are located in the Washington, D. C. area as part of the Headquarters divisions, two offices – the Office of Regulatory Affairs and the Office of Criminal Investigations – are field offices with a workforce spread across the country. The Office of Regulatory Affairs is considered the "eyes and ears" of the agency, conducting the vast majority of the FDA's work in the field. Consumer Safety Officers, more called Investigators, are the individuals who inspect production and warehousing facilities, investigate complaints, illnesses, or outbreaks, review documentation in the case of medical devices, biological products, other items where it may be difficult to conduct a physical examination or take a physical sample of the product; the Office of Regulatory Affairs is divided into five regions, which are further divided into 20 districts. Districts are based on the geographic divisions of the federal court system.
Each district comprises a main district office and a number of Resident Posts, which are FDA remote offices that serve a particular geographic area. ORA includes the Agency's network of regulatory laboratories, which analyze any physical samples taken. Though samples are food-related, some laboratories are equipped to analyze drugs and radiation-emitting devices; the Office of Criminal Investigations was established in 1991 to investigate criminal cases. Unlike ORA Investigators, OCI Special Agents are armed, don't focus on technical aspects of the regulated industries. OCI agents pursue and develop cases where individuals and companies have committed criminal actions, such as fraudulent claims, or knowingly and willfully shipping known adulterated goods in interstate commerce. In many cases, OCI pursues cases involving Title 18 violations, in addition to prohibited acts as defined in Chapter III of the FD&C Act. OCI Special Agents come from other criminal investigations backgrounds, work with the Federal Bureau of Investigation, Assistant Attorney General, Interpol.
OCI receives cases from a variety of sources—including ORA, local agencies, the FBI—and works with ORA Investigators to help develop the technical and science-based aspects of a case. OCI is a smaller branch; the FDA works with other federal agencies, including the Department of Agriculture, Drug Enforcement Administration and Border Protection, Consumer Product Safety Commission. Local and state government agencies work with the FDA to provide regulatory inspections and enforcement action; the FDA regulates more than US$2.4 trillion worth of consumer goods, about 25% of consumer expenditures in the United States. This includes $466 billion in food sales, $275 billion in drugs, $60 billion in cosmetics and $18 billion in vitamin supplements. Much of these expenditures are for goods imported into the United States; the FDA's federal budget request for fiscal year 2012 totaled $4.36 billion, while the proposed 2014 budget is $4.7 billion. About $2 billion of this budget is generated by user fees.

Social networking service
A social networking service is an online platform which people use to build social networks or social relations with other people who share similar personal or career interests, backgrounds or real-life connections. The social network is distributed across various computer networks; the social networks are inherently computer networks, linking people and knowledge. Social networking services vary in the number of features, they can incorporate a range of new information and communication tools, operating on desktops and on laptops, on mobile devices such as tablet computers and smartphones. They may feature "web logging" diary entries online. Online community services are sometimes considered social-network services by programmers and users, though in a broader sense, a social-network service provides an individual-centered service whereas online community services are group-centered. Defined as "websites that facilitate the building of a network of contacts in order to exchange various types of content online," social networking sites provide a space for interaction to continue beyond in person interactions.
These computer mediated interactions link members of various networks and may help to both maintain and develop new social ties. Social networking sites allow users to share ideas, digital photos and videos, to inform others about online or real-world activities and events with people in their network. While in-person social networking – such as gathering in a village market to talk about events – has existed since the earliest development of towns, the Web enables people to connect with others who live in different locations, ranging from across a city to across the world. Depending on the social media platform, members may be able to contact any other member. In other cases, members can contact anyone they have a connection to, subsequently anyone that contact has a connection to, so on; the success of social networking services can be seen in their dominance in society today, with Facebook having a massive 2.13 billion active monthly users and an average of 1.4 billion daily active users in 2017.
LinkedIn, a career-oriented social-networking service requires that a member know another member in real life before they contact them online. Some services require members to have a preexisting connection to contact other members; the main types of social networking services contain category places, means to connect with friends, a recommendation system linked to trust. One can categorize social-network services into three types: socializing social network services used for socializing with existing friends online social networks are decentralized and distributed computer networks where users communicate with each other through internet services. Networking social network services used for non-social interpersonal communication social navigation social network services used for helping users to find specific information or resources There have been attempts to standardize these services to avoid the need to duplicate entries of friends and interests. A study reveals that India recorded world's largest growth in terms of social media users in 2013.
A 2013 survey found that 73% of U. S. adults use social-networking sites. There is a variety of social networking services available online. However, most incorporate common features: social networking services are Web 2.0, Internet-based applications user-generated content is the lifeblood of social networking services. Users create service-specific profiles for the site or app that are designed and maintained by the SNS organization social networking services facilitate the development of online social networks by connecting a user's profile with those of other individuals or groups; the variety and evolving range of stand-alone and built-in social networking services in the online space introduces a challenge of definition. Furthermore, the idea that these services are defined by their ability to bring people together and provides too broad a definition; such a broad definition would suggest that the telegraph and telephone were social networking services – not the Internet technologies scholars are intending to describe.
The terminology is unclear, with some referring to social networking services as social media. A recent attempt at providing a clear definition reviewed the prominent literature in the area and identified four commonalities unique to current social networking services: social networking services are interactive Web 2.0 Internet-based applications, user-generated content, such as user-submitted digital photos, text posts, "tagging", online comments, diary-style "web logs", is the lifeblood of the SNS organism, users create service-specific profiles for the site or app that are designed and maintained by the SNS organization, social networking services facilitate the development of social networks online by connecting a user's profile with those of other individuals or groups. The potential for computer networking to facilitate newly improved forms of computer-mediated social interaction was suggested early on. Efforts to support social networks via computer-mediated communication were made in many early online services, including Usenet, ARPANET, LISTSERV, bulletin board services.
Many prototypical features of social networking sites were present in online services such as America Online, CompuServe, ChatNet, The WELL. Early social netw
Chief executive officer
The chief executive officer or just chief executive, is the most senior corporate, executive, or administrative officer in charge of managing an organization – an independent legal entity such as a company or nonprofit institution. CEOs lead a range of organizations, including public and private corporations, non-profit organizations and some government organizations; the CEO of a corporation or company reports to the board of directors and is charged with maximizing the value of the entity, which may include maximizing the share price, market share, revenues or another element. In the non-profit and government sector, CEOs aim at achieving outcomes related to the organization's mission, such as reducing poverty, increasing literacy, etc. In the early 21st century, top executives had technical degrees in science, engineering or law; the responsibility of an organization's CEO are set by the organization's board of directors or other authority, depending on the organization's legal structure.
They can be far-reaching or quite limited and are enshrined in a formal delegation of authority. Responsibilities include being a decision maker on strategy and other key policy issues, leader and executor; the communicator role can involve speaking to the press and the rest of the outside world, as well as to the organization's management and employees. As a leader of the company, the CEO or MD advises the board of directors, motivates employees, drives change within the organization; as a manager, the CEO/MD presides over the organization's day-to-day operations. The term refers to the person who makes all the key decisions regarding the company, which includes all sectors and fields of the business, including operations, business development, human resources, etc; the CEO of a company is not the owner of the company. In some countries, there is a dual board system with two separate boards, one executive board for the day-to-day business and one supervisory board for control purposes. In these countries, the CEO presides over the executive board and the chairman presides over the supervisory board, these two roles will always be held by different people.
This ensures a distinction between management by the executive board and governance by the supervisory board. This allows for clear lines of authority; the aim is to prevent a conflict of interest and too much power being concentrated in the hands of one person. In the United States, the board of directors is equivalent to the supervisory board, while the executive board may be known as the executive committee. In the United States, in business, the executive officers are the top officers of a corporation, the chief executive officer being the best-known type; the definition varies. In the case of a sole proprietorship, an executive officer is the sole proprietor. In the case of a partnership, an executive officer is a managing partner, senior partner, or administrative partner. In the case of a limited liability company, executive officer is any manager, or officer. A CEO has several subordinate executives, each of whom has specific functional responsibilities referred to as senior executives, executive officers or corporate officers.
Subordinate executives are given different titles in different organizations, but one common category of subordinate executive, if the CEO is the president, is the vice-president. An organization may have more than one vice-president, each tasked with a different area of responsibility; some organizations have subordinate executive officers who have the word chief in their job title, such as chief operating officer, chief financial officer and chief technology officer. The public relations-focused position of chief reputation officer is sometimes included as one such subordinate executive officer, but, as suggested by Anthony Johndrow, CEO of Reputation Economy Advisors, it can be seen as "simply another way to add emphasis to the role of a modern-day CEO – where they are both the external face of, the driving force behind, an organisation culture". In the US, the term chief executive officer is used in business, whereas the term executive director is used in the not-for-profit sector; these terms are mutually exclusive and refer to distinct legal duties and responsibilities.
Implicit in the use of these titles, is that the public not be misled and the general standard regarding their use be applied. In the UK, chief executive and chief executive officer are used in both business and the charitable sector; as of 2013, the use of the term director for senior charity staff is deprecated to avoid confusion with the legal duties and responsibilities associated with being a charity director or trustee, which are non-executive roles. In the United Kingdom, the term director is used instead of chief officer". Business publicists since the days of Edward Bernays and his client John D. Rockefeller and more the corporate publicists for Henry Ford, promoted the concept of the "celebrity CEO". Business journalists have adopted this approach, which assumes that the corporate achievements in the arena of manufacturing, wer
Information technology is the use of computers to store, retrieve and manipulate data, or information in the context of a business or other enterprise. IT is considered to be a subset of communications technology. An information technology system is an information system, a communications system or, more speaking, a computer system – including all hardware and peripheral equipment – operated by a limited group of users. Humans have been storing, retrieving and communicating information since the Sumerians in Mesopotamia developed writing in about 3000 BC, but the term information technology in its modern sense first appeared in a 1958 article published in the Harvard Business Review. We shall call it information technology." Their definition consists of three categories: techniques for processing, the application of statistical and mathematical methods to decision-making, the simulation of higher-order thinking through computer programs. The term is used as a synonym for computers and computer networks, but it encompasses other information distribution technologies such as television and telephones.
Several products or services within an economy are associated with information technology, including computer hardware, electronics, internet, telecom equipment, e-commerce. Based on the storage and processing technologies employed, it is possible to distinguish four distinct phases of IT development: pre-mechanical, electromechanical, electronic; this article focuses on the most recent period, which began in about 1940. Devices have been used to aid computation for thousands of years initially in the form of a tally stick; the Antikythera mechanism, dating from about the beginning of the first century BC, is considered to be the earliest known mechanical analog computer, the earliest known geared mechanism. Comparable geared devices did not emerge in Europe until the 16th century, it was not until 1645 that the first mechanical calculator capable of performing the four basic arithmetical operations was developed. Electronic computers, using either valves, began to appear in the early 1940s.
The electromechanical Zuse Z3, completed in 1941, was the world's first programmable computer, by modern standards one of the first machines that could be considered a complete computing machine. Colossus, developed during the Second World War to decrypt German messages, was the first electronic digital computer. Although it was programmable, it was not general-purpose, being designed to perform only a single task, it lacked the ability to store its program in memory. The first recognisably modern electronic digital stored-program computer was the Manchester Baby, which ran its first program on 21 June 1948; the development of transistors in the late 1940s at Bell Laboratories allowed a new generation of computers to be designed with reduced power consumption. The first commercially available stored-program computer, the Ferranti Mark I, contained 4050 valves and had a power consumption of 25 kilowatts. By comparison the first transistorised computer, developed at the University of Manchester and operational by November 1953, consumed only 150 watts in its final version.
Early electronic computers such as Colossus made use of punched tape, a long strip of paper on which data was represented by a series of holes, a technology now obsolete. Electronic data storage, used in modern computers, dates from World War II, when a form of delay line memory was developed to remove the clutter from radar signals, the first practical application of, the mercury delay line; the first random-access digital storage device was the Williams tube, based on a standard cathode ray tube, but the information stored in it and delay line memory was volatile in that it had to be continuously refreshed, thus was lost once power was removed. The earliest form of non-volatile computer storage was the magnetic drum, invented in 1932 and used in the Ferranti Mark 1, the world's first commercially available general-purpose electronic computer. IBM introduced the first hard disk drive as a component of their 305 RAMAC computer system. Most digital data today is still stored magnetically on hard disks, or optically on media such as CD-ROMs.
Until 2002 most information was stored on analog devices, but that year digital storage capacity exceeded analog for the first time. As of 2007 94% of the data stored worldwide was held digitally: 52% on hard disks, 28% on optical devices and 11% on digital magnetic tape, it has been estimated that the worldwide capacity to store information on electronic devices grew from less than 3 exabytes in 1986 to 295 exabytes in 2007, doubling every 3 years. Database management systems emerged in the 1960s to address the problem of storing and retrieving large amounts of data and quickly. One of the earliest such systems was IBM's Information Management System, still deployed more than 50 years later. IMS stores data hierarchically, but in the 1970s Ted Codd proposed an alternative relational storage model based on set theory and predicate logic and the familiar concepts of tables and columns; the first commercially available relational database management system was available from Oracle in 1981. All database management systems consist of a number of components that together allow the data they store to be accessed simultan
International Standard Serial Number
An International Standard Serial Number is an eight-digit serial number used to uniquely identify a serial publication, such as a magazine. The ISSN is helpful in distinguishing between serials with the same title. ISSN are used in ordering, interlibrary loans, other practices in connection with serial literature; the ISSN system was first drafted as an International Organization for Standardization international standard in 1971 and published as ISO 3297 in 1975. ISO subcommittee TC 46/SC 9 is responsible for maintaining the standard; when a serial with the same content is published in more than one media type, a different ISSN is assigned to each media type. For example, many serials are published both in electronic media; the ISSN system refers to these types as electronic ISSN, respectively. Conversely, as defined in ISO 3297:2007, every serial in the ISSN system is assigned a linking ISSN the same as the ISSN assigned to the serial in its first published medium, which links together all ISSNs assigned to the serial in every medium.
The format of the ISSN is an eight digit code, divided by a hyphen into two four-digit numbers. As an integer number, it can be represented by the first seven digits; the last code digit, which may be 0-9 or an X, is a check digit. Formally, the general form of the ISSN code can be expressed as follows: NNNN-NNNC where N is in the set, a digit character, C is in; the ISSN of the journal Hearing Research, for example, is 0378-5955, where the final 5 is the check digit, C=5. To calculate the check digit, the following algorithm may be used: Calculate the sum of the first seven digits of the ISSN multiplied by its position in the number, counting from the right—that is, 8, 7, 6, 5, 4, 3, 2, respectively: 0 ⋅ 8 + 3 ⋅ 7 + 7 ⋅ 6 + 8 ⋅ 5 + 5 ⋅ 4 + 9 ⋅ 3 + 5 ⋅ 2 = 0 + 21 + 42 + 40 + 20 + 27 + 10 = 160 The modulus 11 of this sum is calculated. For calculations, an upper case X in the check digit position indicates a check digit of 10. To confirm the check digit, calculate the sum of all eight digits of the ISSN multiplied by its position in the number, counting from the right.
The modulus 11 of the sum must be 0. There is an online ISSN checker. ISSN codes are assigned by a network of ISSN National Centres located at national libraries and coordinated by the ISSN International Centre based in Paris; the International Centre is an intergovernmental organization created in 1974 through an agreement between UNESCO and the French government. The International Centre maintains a database of all ISSNs assigned worldwide, the ISDS Register otherwise known as the ISSN Register. At the end of 2016, the ISSN Register contained records for 1,943,572 items. ISSN and ISBN codes are similar in concept. An ISBN might be assigned for particular issues of a serial, in addition to the ISSN code for the serial as a whole. An ISSN, unlike the ISBN code, is an anonymous identifier associated with a serial title, containing no information as to the publisher or its location. For this reason a new ISSN is assigned to a serial each time it undergoes a major title change. Since the ISSN applies to an entire serial a new identifier, the Serial Item and Contribution Identifier, was built on top of it to allow references to specific volumes, articles, or other identifiable components.
Separate ISSNs are needed for serials in different media. Thus, the print and electronic media versions of a serial need separate ISSNs. A CD-ROM version and a web version of a serial require different ISSNs since two different media are involved. However, the same ISSN can be used for different file formats of the same online serial; this "media-oriented identification" of serials made sense in the 1970s. In the 1990s and onward, with personal computers, better screens, the Web, it makes sense to consider only content, independent of media; this "content-oriented identification" of serials was a repressed demand during a decade, but no ISSN update or initiative occurred. A natural extension for ISSN, the unique-identification of the articles in the serials, was the main demand application. An alternative serials' contents model arrived with the indecs Content Model and its application, the digital object identifier, as ISSN-independent initiative, consolidated in the 2000s. Only in 2007, ISSN-L was defined in the
