Strategic Defense Initiative
The Strategic Defense Initiative was a proposed missile defense system intended to protect the United States from attack by ballistic strategic nuclear weapons. The concept was first announced publicly by President Ronald Reagan on 23 March 1983. Reagan was a vocal critic of the doctrine of mutual assured destruction, which he described as a "suicide pact", he called upon the scientists and engineers of the United States to develop a system that would render nuclear weapons obsolete; the Strategic Defense Initiative Organization was set up in 1984 within the United States Department of Defense to oversee development. A wide array of advanced weapon concepts, including lasers, particle beam weapons and ground- and space-based missile systems were studied, along with various sensor and control, high-performance computer systems that would be needed to control a system consisting of hundreds of combat centers and satellites spanning the entire globe. A number of these concepts were tested through the late 1980s, follow-on efforts and spin-offs continue to this day.
Under the SDIO's Innovative Sciences and Technology Office, headed by physicist and engineer Dr. James Ionson, the investment was predominantly made in basic research at national laboratories, in industry. In 1987, the American Physical Society concluded that the technologies being considered were decades away from being ready for use, at least another decade of research was required to know whether such a system was possible. After the publication of the APS report, SDIs budget was cut. By the late 1980s, the effort had been re-focused on the "Brilliant Pebbles" concept using small orbiting missiles not unlike a conventional air-to-air missile, expected to be much less expensive to develop and deploy. SDI was controversial throughout its history, was criticized for threatening to destabilize the MAD-approach and to re-ignite "an offensive arms race". SDI was derisively nicknamed by Democratic Senator Ted Kennedy as "Star Wars", after the 1977 film by George Lucas. By the early 1990s, with the Cold War ending and nuclear arsenals being reduced, political support for SDI collapsed.
SDI ended in 1993, when the administration of President Bill Clinton redirected the efforts towards theatre ballistic missiles and renamed the agency the Ballistic Missile Defense Organization. BMDO was renamed the Missile Defense Agency in 2002; the US Army had considered the issue of ballistic missile defense as early as late in World War II. Studies on the topic suggested attacking a V-2 rocket would be difficult because the flight time was so short that it would leave little time to forward information through command and control networks to the missile batteries that would attack them. Bell Labs pointed out that although longer-range missiles flew much faster, their longer flight times would address the timing issue and their high altitudes would make long-range detection by radar easier; this led to a series of projects including Nike Zeus, Nike-X, Sentinel and the Safeguard Program, all aimed at deploying a nationwide defensive system against attacks by Soviet ICBMs. The reason for so many programs was the changing strategic threat.
Low-cost countermeasures like radar decoys required additional interceptors to counter. An early estimate suggested one would have to spend $20 on defense for every $1 the Soviets spent on offense; the addition of MIRV in the late 1960s further upset the balance in favor of offense systems. This cost-exchange ratio was so favorable that it appeared the only thing building a defense would do would be to cause an arms race; when faced with this problem, President Eisenhower asked ARPA to consider alternative concepts. Their Project Defender studied all sorts of systems, before abandoning most of them to concentrate on Project BAMBI. BAMBI used a series of satellites carrying interceptor missiles that would attack the Soviet ICBMs shortly after launch; this boost phase intercept rendered MIRV impotent. The operational cost of such a system would be enormous, the US Air Force continually rejected such concepts. Development was cancelled in 1963. Through this period, the entire topic of BMD became controversial.
Early deployment plans were met with little interest, but by the late 1960s, public meetings on the Sentinel system were met by thousands of angry protesters. After thirty years of effort, only one such system would be built. A Soviet military A-35 anti-ballistic missile system was deployed around Moscow to intercept enemy ballistic missiles targeting the city or its surrounding areas; the A-35 was the only Soviet ABM system allowed under the 1972 Anti-Ballistic Missile Treaty. In development since the 1960s and in operation from 1971 until the 1990s, it featured the nuclear-tipped A350 exoatmospheric interceptor missile. George Shultz, Secretary of State under Reagan, suggests that a 1967 lecture by physicist Edward Teller (the so-called "father
OCLC Online Computer Library Center, Incorporated d/b/a OCLC is an American nonprofit cooperative organization "dedicated to the public purposes of furthering access to the world's information and reducing information costs". It was founded in 1967 as the Ohio College Library Center. OCLC and its member libraries cooperatively produce and maintain WorldCat, the largest online public access catalog in the world. OCLC is funded by the fees that libraries have to pay for its services. OCLC maintains the Dewey Decimal Classification system. OCLC began in 1967, as the Ohio College Library Center, through a collaboration of university presidents, vice presidents, library directors who wanted to create a cooperative computerized network for libraries in the state of Ohio; the group first met on July 5, 1967 on the campus of the Ohio State University to sign the articles of incorporation for the nonprofit organization, hired Frederick G. Kilgour, a former Yale University medical school librarian, to design the shared cataloging system.
Kilgour wished to merge the latest information storage and retrieval system of the time, the computer, with the oldest, the library. The plan was to merge the catalogs of Ohio libraries electronically through a computer network and database to streamline operations, control costs, increase efficiency in library management, bringing libraries together to cooperatively keep track of the world's information in order to best serve researchers and scholars; the first library to do online cataloging through OCLC was the Alden Library at Ohio University on August 26, 1971. This was the first online cataloging by any library worldwide. Membership in OCLC is based on use of services and contribution of data. Between 1967 and 1977, OCLC membership was limited to institutions in Ohio, but in 1978, a new governance structure was established that allowed institutions from other states to join. In 2002, the governance structure was again modified to accommodate participation from outside the United States.
As OCLC expanded services in the United States outside Ohio, it relied on establishing strategic partnerships with "networks", organizations that provided training and marketing services. By 2008, there were 15 independent United States regional service providers. OCLC networks played a key role in OCLC governance, with networks electing delegates to serve on the OCLC Members Council. During 2008, OCLC commissioned two studies to look at distribution channels. In early 2009, OCLC negotiated new contracts with the former networks and opened a centralized support center. OCLC provides bibliographic and full-text information to anyone. OCLC and its member libraries cooperatively produce and maintain WorldCat—the OCLC Online Union Catalog, the largest online public access catalog in the world. WorldCat has holding records from private libraries worldwide; the Open WorldCat program, launched in late 2003, exposed a subset of WorldCat records to Web users via popular Internet search and bookselling sites.
In October 2005, the OCLC technical staff began a wiki project, WikiD, allowing readers to add commentary and structured-field information associated with any WorldCat record. WikiD was phased out; the Online Computer Library Center acquired the trademark and copyrights associated with the Dewey Decimal Classification System when it bought Forest Press in 1988. A browser for books with their Dewey Decimal Classifications was available until July 2013; until August 2009, when it was sold to Backstage Library Works, OCLC owned a preservation microfilm and digitization operation called the OCLC Preservation Service Center, with its principal office in Bethlehem, Pennsylvania. The reference management service QuestionPoint provides libraries with tools to communicate with users; this around-the-clock reference service is provided by a cooperative of participating global libraries. Starting in 1971, OCLC produced catalog cards for members alongside its shared online catalog. OCLC commercially sells software, such as CONTENTdm for managing digital collections.
It offers the bibliographic discovery system WorldCat Discovery, which allows for library patrons to use a single search interface to access an institution's catalog, database subscriptions and more. OCLC has been conducting research for the library community for more than 30 years. In accordance with its mission, OCLC makes its research outcomes known through various publications; these publications, including journal articles, reports and presentations, are available through the organization's website. OCLC Publications – Research articles from various journals including Code4Lib Journal, OCLC Research, Reference & User Services Quarterly, College & Research Libraries News, Art Libraries Journal, National Education Association Newsletter; the most recent publications are displayed first, all archived resources, starting in 1970, are available. Membership Reports – A number of significant reports on topics ranging from virtual reference in libraries to perceptions about library funding. Newsletters – Current and archived newsletters for the library and archive community.
Presentations – Presentations from both guest speakers and OCLC research from conferences and other events. The presentations are organized into five categories: Conference presentations, Dewey presentations, Distinguished Seminar Series, Guest presentations, Research staff

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
American Physical Society
The American Physical Society is the world's second largest organization of physicists. The Society publishes more than a dozen scientific journals, including the prestigious Physical Review and Physical Review Letters, organizes more than twenty science meetings each year. APS is a member society of the American Institute of Physics; the American Physical Society was founded on May 20, 1899, when thirty-six physicists gathered at Columbia University for that purpose. They proclaimed the mission of the new Society to be "to advance and diffuse the knowledge of physics", in one way or another the APS has been at that task since. In the early years the sole activity of the APS was to hold scientific meetings four per year. In 1913, the APS took over the operation of the Physical Review, founded in 1893 at Cornell University, journal publication became its second major activity; the Physical Review was followed by Reviews of Modern Physics in 1929 and by Physical Review Letters in 1958. Over the years, Phys.
Rev. has subdivided into five separate sections as the fields of physics proliferated and the number of submissions grew. In more recent years, the activities of the Society have broadened considerably. Stimulated by the increase in Federal funding in the period after the Second World War, more by the increased public involvement of scientists in the 1960s, the APS is active in public and governmental affairs, in the international physics community. In addition, the Society conducts extensive programs in education, science outreach, media relations. APS has 11 topical groups covering all areas of physics research. There are 6 forums that reflect the interest of its 50,000 members in broader issues, 9 sections organized by geographical region. In 1999, APS Physics celebrated its centennial with the biggest-ever physics meeting in Atlanta. In 2005, APS took the lead role in United States participation in the World Year of Physics, initiating several programs to broadly publicize physics during the 100th anniversary of Albert Einstein's annus mirabilis.
Einstein@Home, one of the projects APS initiated during World Year of Physics, is an ongoing and popular distributed computing project. During the summer of 2005, the society conducted an electronic poll, in which the majority of APS members preferred the name American Physics Society; the poll became the motivation for a proposal of a name change promised in the leadership election that year. However, because of legal issues, the planned name change was abandoned by the APS Executive Board. To promote public recognition of APS as a physics society, while retaining the name American Physical Society, the APS Executive Board adopted a new logo incorporating the phrase "APS Physics." General use of APS Physics to refer to APS or the American Physical Society is encouraged. The new APS Physics logo was designed by Kerry G. Johnson. Marvin Cohen, APS President, said, "I like the logo. At least now when you are in an elevator at an APS meeting and someone looks at your badge, they won't ask you about sports."
The American Physical Society publishes 13 international research journals and an open-access on-line news and commentary website Physics. Physical Review Letters Reviews of Modern Physics Physical Review A: Atomic and optical physics. Physical Review B: Condensed matter and materials physics. Physical Review C: Nuclear physics. Physical Review D: Particles, fields and cosmology. Physical Review E: Statistical and soft matter physics. Physical Review X: Open access. Physical Review Applied: Experimental and theoretical applications of physics. Physical Review Fluids: Fluid dynamics. Physical Review Accelerators and Beams: Open access. Physical Review Physics Education Research: Open access. Physical Review Materials: A broad-scope international journal for the multidisciplinary community engaged in research on materials. All members of APS receive the monthly publication Physics Today, published by the American Institute of Physics; the Society publishes Inside Science, part of a news service launched in 1999 to place more science stories in the media.
Aimed at both introducing the public to new scientific research and at correcting public misconceptions about science, the publication has editorial independence from APS itself. The American Physical Society has 47 units that represent the wide range of interests of the physics community. Astrophysics Atomic, Molecular & Optical Physics: The objective of the division is the promotion of the fundamental research on atoms, simple molecules and light, their interactions; this is the oldest division of the American Physical Society. It was created in 1943; the division manages a number of prestigious awards for AMO scientists at various stages of their careers, such as the Davisson-Germer Prize in Atomic or Surface Physics, Rabi Prize in AMO Physics, Outstanding Doctoral Thesis Research in AMO Physics, Herbert P. Broida Prize, etc, it organizes annual DAMOP Meetings attended by many leading AMO researchers, both from the United States and abroad. Biological Physics: With over 2,000 members, the division is the second largest learned society in the world devoted to biological physics, following the Biophysical Society.
The objective of the division is the advancement and dissemination of knowledge on the broad interface of physics and biology. This includes st
A magazine is a publication a periodical publication, printed or electronically published. Magazines are published on a regular schedule and contain a variety of content, they are financed by advertising, by a purchase price, by prepaid subscriptions, or a combination of the three. At its root, the word "magazine" refers to a storage location. In the case of written publication, it is a collection of written articles; this explains why magazine publications share the word root with gunpowder magazines, artillery magazines, firearms magazines, and, in French, retail stores such as department stores. By definition, a magazine paginates with each issue starting at page three, with the standard sizing being 8 3⁄8 in × 10 7⁄8 in. However, in the technical sense a journal has continuous pagination throughout a volume, thus Business Week, which starts each issue anew with page one, is a magazine, but the Journal of Business Communication, which starts each volume with the winter issue and continues the same sequence of pagination throughout the coterminous year, is a journal.
Some professional or trade publications are peer-reviewed, an example being the Journal of Accountancy. Academic or professional publications that are not peer-reviewed are professional magazines; that a publication calls itself a journal does not make it a journal in the technical sense. Magazines can be distributed through the mail, through sales by newsstands, bookstores, or other vendors, or through free distribution at selected pick-up locations; the subscription business models for distribution fall into three main categories. In this model, the magazine is sold to readers for a price, either on a per-issue basis or by subscription, where an annual fee or monthly price is paid and issues are sent by post to readers. Paid circulation allows for defined readership statistics; this means that there is no cover price and issues are given away, for example in street dispensers, airline, or included with other products or publications. Because this model involves giving issues away to unspecific populations, the statistics only entail the number of issues distributed, not who reads them.
This is the model used by many trade magazines distributed only to qualifying readers for free and determined by some form of survey. Because of costs associated with the medium of print, publishers may not distribute free copies to everyone who requests one; this allows a high level of certainty that advertisements will be received by the advertiser's target audience, it avoids wasted printing and distribution expenses. This latter model was used before the rise of the World Wide Web and is still employed by some titles. For example, in the United Kingdom, a number of computer-industry magazines use this model, including Computer Weekly and Computing, in finance, Waters Magazine. For the global media industry, an example would be VideoAge International; the earliest example of magazines was Erbauliche Monaths Unterredungen, a literary and philosophy magazine, launched in 1663 in Germany. The Gentleman's Magazine, first published in 1731, in London was the first general-interest magazine. Edward Cave, who edited The Gentleman's Magazine under the pen name "Sylvanus Urban", was the first to use the term "magazine," on the analogy of a military storehouse.
Founded by Herbert Ingram in 1842, The Illustrated London News was the first illustrated magazine. The oldest consumer magazine still in print is The Scots Magazine, first published in 1739, though multiple changes in ownership and gaps in publication totalling over 90 years weaken that claim. Lloyd's List was founded in Edward Lloyd's England coffee shop in 1734. Under the ancient regime, the most prominent magazines were Mercure de France, Journal des sçavans, founded in 1665 for scientists, Gazette de France, founded in 1631. Jean Loret was one of France's first journalists, he disseminated the weekly news of music and Parisian society from 1650 until 1665 in verse, in what he called a gazette burlesque, assembled in three volumes of La Muse historique. The French press lagged a generation behind the British, for they catered to the needs the aristocracy, while the newer British counterparts were oriented toward the middle and working classes. Periodicals were censored by the central government in Paris.
They were not quiescent politically—often they criticized Church abuses and bureaucratic ineptitude. They supported the monarchy and they played at most a small role in stimulating the revolution. During the Revolution, new periodicals played central roles as propaganda organs for various factions. Jean-Paul Marat was the most prominent editor, his L'Ami du peuple advocated vigorously for the rights of the lower classes against the enemies of the people Marat hated. After 1800 Napoleon reimposed strict censorship. Magazines flourished after Napoleon left in 1815. Most were based in Paris and most emphasized literature and stories, they served religious and political communities. In times of political crisis they expressed and helped shape the views of their readership and thereby were major
Web of Science
Web of Science is an online subscription-based scientific citation indexing service produced by the Institute for Scientific Information maintained by Clarivate Analytics, that provides a comprehensive citation search. It gives access to multiple databases that reference cross-disciplinary research, which allows for in-depth exploration of specialized sub-fields within an academic or scientific discipline. A citation index is built on the fact that citations in science serve as linkages between similar research items, lead to matching or related scientific literature, such as journal articles, conference proceedings, etc. In addition, literature which shows the greatest impact in a particular field, or more than one discipline, can be located through a citation index. For example, a paper's influence can be determined by linking to all the papers. In this way, current trends and emerging fields of research can be assessed. Eugene Garfield, the "father of citation indexing of academic literature," who launched the Science Citation Index, which in turn led to the Web of Science, wrote: Citations are the formal, explicit linkages between papers that have particular points in common.
A citation index is built around these linkages. It identifies the sources of the citations. Anyone conducting a literature search can find from one to dozens of additional papers on a subject just by knowing one, cited, and every paper, found provides a list of new citations with which to continue the search. The simplicity of citation indexing is one of its main strengths. Web of Science is described as a unifying research tool which enables the user to acquire and disseminate database information in a timely manner; this is accomplished because of the creation of a common vocabulary, called ontology, for varied search terms and varied data. Moreover, search terms generate related information across categories. Acceptable content for Web of Science is determined by an evaluation and selection process based on the following criteria: impact, timeliness, peer review, geographic representation. Web of Science employs various analysis capabilities. First, citation indexing is employed, enhanced by the capability to search for results across disciplines.
The influence, impact and methodology of an idea can be followed from its first instance, notice, or referral to the present day. This technology points to a deficiency with the keyword-only method of searching. Second, subtle trends and patterns relevant to the literature or research of interest, become apparent. Broad trends indicate significant topics of the day, as well as the history relevant to both the work at hand, particular areas of study. Third, trends can be graphically represented. Expanding the coverage of Web of Science, in November 2009 Thomson Reuters introduced Century of Social Sciences; this service contains files which trace social science research back to the beginning of the 20th century, Web of Science now has indexing coverage from the year 1900 to the present. As of 3 September 2014, the multidisciplinary coverage of the Web of Science encompasses over 50,000 scholarly books, 12,000 journals and 160,000 conference proceedings; the selection is made on the basis of impact evaluations and comprise open-access journals, spanning multiple academic disciplines.
The coverage includes: the sciences, social sciences and humanities, goes across disciplines. However, Web of Science does not index all journals. There is a positive correlation between Impact Factor and CiteScore. However, analysis by Elsevier has identified 216 journals from 70 publishers to be in the top 10 percent of the most-cited journals in their subject category based on the CiteScore while they did not have Impact Factor, it appears that Impact Factor does not provide a comprehensive and an unbiased coverage of high quality journals. Similar results can be observed by comparing Impact Factor with SCImago Journal Rank. Furthermore, as of September 3, 2014 the total file count of the Web of Science was 90 million records, which included over a billion cited references; this citation service on average indexes around 65 million items per year, it is described as the largest accessible citation database. Titles of foreign-language publications are translated into English and so cannot be found by searches in the original language.
The Web of Science Core Collection consists of six online databases: Science Citation Index Expanded covers more than 8,500 notable journals encompassing 150 disciplines. Coverage is from the year 1900 to the present day. Social Sciences Citation Index covers more than 3,000 journals in social science disciplines. Range of coverage is from the year 1900 to the present day. Arts & Humanities Citation Index covers more than 1,700 arts and humanities journals starting from 1975. In addition, 250 major scientific and social sciences journals are covered. Emerging Sources Citation Index covers over 5,000 journals in the sciences, social science, humanities. Book Citation Index covers more than 60,000 editorially selected books starting from 2005. Conference Proceedings Citation Index covers more than 160,000 conference titles in the Sciences starting from 1990 to the present day Since 2008, the Web of Science hosts a number of regional citation indices; the Chinese Science Citation Database, produced in partnership with the Chinese Academy of Sciences, was the first one in a language other than English.
It was followed in 2013 by the SciELO Citation Index, covering Brazil, Portugal, the Cari
