The American Association for the Advancement of Science (AAAS) is an American international non-profit organization with the stated mission of promoting cooperation among scientists, defending scientific freedom, encouraging scientific responsibility, and supporting scientific education and science outreach for the betterment of all humanity. AAAS was the first permanent organization established to promote science and engineering nationally and to represent the interests of American researchers from across all scientific fields. It is the world's largest general scientific society, with over 120,000 members, and is the publisher of the well-known scientific journal Science.

History

Creation

The American Association for the Advancement of Science was created on September 20, 1848, at the Academy of Natural Sciences in Philadelphia, Pennsylvania. It was a reformation of the Association of American Geologists and Naturalists with the broadened mission to be the first permanent organization to promote science and engineering nationally and to represent the interests of American researchers from across all scientific fields The Society chose William Charles Redfield as their first president because he had proposed the most comprehensive plans for the organization. According to the first constitution which was agreed to at the September 20 meeting, the goal of the society was to promote scientific dialogue in order to allow for greater scientific collaboration. By doing so the association aimed to use resources to conduct science with increased efficiency and allow for scientific progress at a greater rate. The association also sought to increase the resources available to the scientific community through active advocacy of science. There were only 78 members when the AAAS was formed. As a member of the new scientific body, Matthew Fontaine Maury, USN was one of those who attended the first 1848 meeting.

At a meeting held on Friday afternoon, September 22, 1848, Redfield presided, and Matthew Fontaine Maury gave a full scientific report on his Wind and Current Charts. Maury stated that hundreds of ship navigators were now sending abstract logs of their voyages to the United States Naval Observatory. He added, "Never before was such a corps of observers known." But, he pointed out to his fellow scientists, his critical need was for more "simultaneous observations." "The work," Maury stated, "is not exclusively for the benefit of any nation or age." The minutes of the AAAS meeting reveal that because of the universality of this "view on the subject, it was suggested whether the states of Christendom might not be induced to cooperate with their Navies in the undertaking; at least so far as to cause abstracts of their log-books and sea journals to be furnished to Matthew F. Maury, USN, at the Naval Observatory at Washington."

William Barton Rogers, professor at the University of Virginia and later founder of the Massachusetts Institute of Technology, offered a resolution: "Resolved that a Committee of five be appointed to address a memorial to the Secretary of the Navy, requesting his further aid in procuring for Matthew Maury the use of the observations of European and other foreign navigators, for the extension and perfecting of his charts of winds and currents." The resolution was adopted and, in addition to Rogers, the following members of the association were appointed to the committee: Professor Joseph Henry of Washington; Professor Benjamin Peirce of Cambridge, Massachusetts; Professor James H. Coffin of Easton, Pennsylvania, and Professor Stephen Alexander of Princeton, New Jersey. This was scientific cooperation, and Maury went back to Washington with great hopes for the future.

In 1850, the first female members were accepted, they were: astronomer Maria Mitchell, entomologist Margaretta Morris. Science educator Almira Hart Lincoln Phelps was elected in 1859.

Growth and Civil War dormancy

By 1860, membership increased to over 2,000. The AAAS became dormant during the American Civil War; their August 1861 meeting in Nashville, Tennessee, was postponed indefinitely after the outbreak of the first major engagement of the war at Bull Run. The AAAS did not become a permanent casualty of the war.

In 1866, Frederick Barnard presided over the first meeting of the resurrected AAAS at a meeting in New York City. Following the revival of the AAAS, the group had considerable growth. The AAAS permitted all people, regardless of scientific credentials, to join. The AAAS did, however, institute a policy of granting the title of "Fellow of the AAAS" to well-respected scientists within the organization. The years of peace brought the development and expansion of other scientific-oriented groups. The AAAS's focus on the unification of many fields of science under a single organization was in contrast to the many new science organizations founded to promote a single discipline. For example, the American Chemical Society, founded in 1876, promotes chemistry.

In 1863, the US Congress established the National Academy of Sciences, another multidisciplinary sciences organization. It elects members based on recommendations from colleagues and the value of published works.

Twentieth century

Advocacy

Alan I. Leshner, AAAS CEO from 2001 until 2015, published many op-ed articles discussing how many people integrate science and religion in their lives. He has opposed the insertion of non-scientific content, such as creationism or intelligent design, into the scientific curriculum of schools.

In December 2006, the AAAS adopted an official statement on climate change, in which they stated, "The scientific evidence is clear: global climate change caused by human activities is occurring now, and it is a growing threat to society....The pace of change and the evidence of harm have increased markedly over the last five years. The time to control greenhouse gas emissions is now."

In February 2007, the AAAS used satellite images to document human rights abuses in Burma. The next year, AAAS launched the Center for Science Diplomacy to advance both science and the broader relationships among partner countries, by promoting science diplomacy and international scientific cooperation.

In 2012, AAAS published op-eds, held events on Capitol Hill and released analyses of the U.S. federal research-and-development budget, to warn that a budget sequestration would have severe consequences for scientific progress.

AAAS officers and senior officials in 1947. Left to right, standing: Sinnott, Baitsell, Payne, Lark-Horovitz, Miles, Stakman, sitting: Carlson, Mather, Moulton, Shapley.

The most recent Constitution of the AAAS, enacted on January 1, 1973, establishes that the governance of the AAAS is accomplished through four entities: a President, a group of administrative officers, a Council, and a board of directors.

Presidents

Main article: President of the American Association for the Advancement of Science

Individuals elected to the presidency of the AAAS hold a three-year term in a unique way. The first year is spent as president-elect, the second as president and the third as chairperson of the board of directors. In accordance with the convention followed by the AAAS, presidents are referenced by the year in which they left office.

Geraldine Richmond is the president of AAAS for 2015–16; Phillip Sharp is the board chair; and Barbara A. Schaal is the president-elect. Each took office on the last day of the 2015 AAAS Annual Meeting in February 2015. On the last day of the 2016 AAAS Annual Meeting, February 15, 2016, Richmond will become the chair, Schaal will become the president, and a new president-elect will take office.

Past presidents of AAAS have included some of the most important scientific figures of their time. Among them: explorer and geologist John Wesley Powell (1888); astronomer and physicist Edward Charles Pickering (1912); anthropologist Margaret Mead (1975); and biologist Stephen Jay Gould (2000).

Administrative officers

There are three classifications of high-level administrative officials that execute the basic, daily functions of the AAAS. These are the executive officer, the treasurer and then each of the AAAS's section secretaries. The current CEO of AAAS and executive publisher of Science magazine is Sudip Parikh. The current Editor in Chief of Science magazine is Holden Thorp.

Sections of the AAAS

The AAAS has 24 "sections" with each section being responsible for a particular concern of the AAAS. There are sections for agriculture, anthropology, astronomy, atmospheric science, biological science, chemistry, dentistry, education, engineering, general interest in science and engineering, geology and geography, the history and philosophy of science, technology, computer science, linguistics, mathematics, medical science, neuroscience, pharmaceutical science, physics, psychology, science and human rights, social and political science, the social impact of science and engineering, and statistics.

Affiliates

AAAS affiliates include 262 societies and academies of science, serving more than 10 million members, from the Acoustical Society of America to the Wildlife Society, as well as non-mainstream groups like the Parapsychological Association.

The Council

The council is composed of the members of the Board of Directors, the retiring section chairmen, elected delegates and affiliated foreign council members. Among the elected delegates there are always at least two members from the National Academy of Sciences and one from each region of the country. The President of the AAAS serves as the Chairperson of the council. Members serve the council for a term of three years.

The council meets annually to discuss matters of importance to the AAAS. They have the power to review all activities of the Association, elect new fellows, adopt resolutions, propose amendments to the Association's constitution and bylaws, create new scientific sections, and organize and aid local chapters of the AAAS. The Council recently has new additions to it from different sections which include many youngsters as well. John Kerry of Chicago is the youngest American in the council and Akhil Ennamsetty of India is the youngest foreign council member.

Board of directors

The board of directors is composed of a chairperson, the president, and the president-elect along with eight elected directors, the executive officer of the association and up to two additional directors appointed by elected officers. Members serve a four-year term except for directors appointed by elected officers, who serve three-year terms.

The current chairman is Gerald Fink, Margaret and Herman Sokol Professor at Whitehead Institute, MIT. Fink will serve in the post until the end of the 2016 AAAS Annual Meeting, 15 February 2016. (The chairperson is always the immediate past-president of AAAS.)

The board of directors has a variety of powers and responsibilities. It is charged with the administration of all association funds, publication of a budget, appointment of administrators, proposition of amendments, and determining the time and place of meetings of the national association. The board may also speak publicly on behalf of the association. The board must also regularly correspond with the council to discuss their actions.

AAAS Fellows

Main article: Fellow of the American Association for the Advancement of Science

The AAAS council elects every year, its members who are distinguished scientifically, to the grade of fellow (FAAAS). Election to AAAS is an honor bestowed by their peers and elected fellows are presented with a certificate and rosette pin. To limit the effects and tolerance of sexual harassment in the sciences, starting 15 October 2018, a Fellow's status can be revoked "in cases of proven scientific misconduct, serious breaches of professional ethics, or when the Fellow in the view of the AAAS otherwise no longer merits the status of Fellow."

Meetings

Formal meetings of the AAAS are numbered consecutively, starting with the first meeting in 1848. Meetings were not held 1861–1865 during the American Civil War, and also 1942–1943 during World War II. Since 1946, one meeting has occurred annually, now customarily in February.

Awards and fellowships

Each year, the AAAS gives out a number of honorary awards, most of which focus on science communication, journalism, and outreach – sometimes in partnership with other organizations. The awards recognize "scientists, journalists, and public servants for significant contributions to science and to the public's understanding of science". The awards are presented each year at the association's annual meeting.

The AAAS also offers a number of fellowship programs.

Currently active awards include

• Award for Science and Diplomacy
• Early Career Award for Public Engagement with Science

Publications

The society's flagship publication is Science, a weekly interdisciplinary scientific journal. Other peer-reviewed journals published by the AAAS in the "Science family of journals" are Science Signaling, Science Translational Medicine, Science Immunology, Science Robotics and the interdisciplinary Science Advances. They also publish the non-peer-reviewed Science & Diplomacy. The society previously published the review journal Science Books & Films (SB&F). AAAS also publishes on behalf of other organizations through the Science Partner Journals (SPJ) program, with a focus on online-only open access journals.

SciLine

SciLine is a philanthropically funded and editorially independent service for journalists and scientists. Its launch was announced in an October 27, 2017 article in Science by founding director Rick Weiss, former communications chief at the White House Office of Science and Technology Policy and science reporter at the Washington Post. Its stated mission is to increase the amount and quality of research-backed evidence in news stories by connecting U.S. journalists to scientists and to validated scientific information.

Reporters in the United States can access SciLine's services, which include expert-matching, general media briefings, expert quote sheets, and quick fact sheets. As of July 2021, SciLine had fulfilled approximately 2,000 requests from 650 journalists through its expert-matching service.

SciLine's financial supporters include the Quadrivium Foundation, the Chan Zuckerberg Initiative, the John S. and James L. Knight Foundation, the Rita Allen Foundation, and the Heinz Endowments. AAAS provides in-kind support.

EurekAlert!

In 1996, AAAS launched the EurekAlert! website, an editorially independent, non-profit news release distribution service covering all areas of science, medicine and technology. EurekAlert! provides news in English, Spanish, French, German, Portuguese, Japanese, and, from 2007, in Chinese.

Working staff journalists and freelancers who meet eligibility guidelines can access the latest studies before publication and obtain embargoed information in compliance with the U.S. Securities and Exchange Commission's Regulation Fair Disclosure policy. By early 2018, more than 14,000 reporters from more than 90 countries have registered for free access to embargoed materials. More than 5,000 active public information officers from 2,300 universities, academic journals, government agencies, and medical centers are credentialed to provide new releases to reporters and the public through the system.

In 1998, European science organizations countered Eurekalert! with a press release distribution service AlphaGalileo.

EurekAlert! has fallen under criticism for lack of press release standards and for generating churnalism.

The U.S. National Science Foundation (NSF) is an independent agency of the United States federal government that supports fundamental research and education in all the non-medical fields of science and engineering. Its medical counterpart is the National Institutes of Health. With an annual budget of about $9.9 billion (fiscal year 2023), the NSF funds approximately 25% of all federally supported basic research conducted by the United States' colleges and universities. In some fields, such as mathematics, computer science, economics, and the social sciences, the NSF is the major source of federal backing.

NSF's director and deputy director are appointed by the president of the United States and confirmed by the United States Senate, whereas the 24 president-appointed members of the National Science Board (NSB) do not require U.S. Senate confirmation. The director and deputy director are responsible for administration, planning, budgeting and day-to-day operations of the foundation, while the NSB meets six times a year to establish its overall policies. The current NSF director is Sethuraman Panchanathan.

History

Founding

The U.S. National Science Foundation (NSF) was established by the National Science Foundation Act of 1950. Its stated mission is "to promote the progress of science, to advance the national health, prosperity, and welfare, and to secure the national defense." The NSF's scope has expanded over the years to include many areas that were not in its initial portfolio, including the social and behavioral sciences, engineering, and science and mathematics education. The NSF is the only U.S. federal agency with a mandate to support all non-medical fields of research.

Budget and performance history

Since the technology boom of the 1980s, the U.S. Congress has generally embraced the premise that government-funded basic research is essential for the nation's economic health and global competitiveness, and for national defense. This support has manifested in an expanding National Science Foundation budget from $1 billion in 1983 to $8.28 billion in 2020. 

NSF has published annual reports since 1950, which since the new millennium have been two reports, variously called "Performance Report" and "Accountability Report" or "Performance Highlights" and "Financial Highlights"; the latest available FY 2013 Agency Financial Report was posted December 16, 2013, and the six-page FY 2013 Performance and Financial Highlights was posted March 25, 2013. More recently, the NSF has focused on obtaining high return on investment from their spending on scientific research.

Various bills have sought to direct funds within the NSF. In 1981, the Office of Management and Budget (OMB) introduced a proposal to reduce the NSF social sciences directorate's budget by 75%. Economist Robert A. Moffit suggests a connection between this proposal and Democratic Senator William Proxmire's Golden Fleece Award series criticizing "frivolous" government spending — Proxmire's first Golden Fleece had been awarded to the NSF in 1975 for granting $84,000 to a social science project investigating why people fall in love. Ultimately, the OMB's 75% reduction proposal failed, but the NSF Economics Program budget did fall 40%. In 2012, political science research was barred from NSF funding by the passage of the Flake Amendment, breaking the precedent of granting the NSF autonomy to determine its own priorities.

Funding Profile

In Fiscal Year 2020, NSF received 42,400 proposals and awarded 12,100, for a funding rate of 28%. In FY 2021, the estimates are 43,200 and 11,500 respectively, giving a funding rate of 26.6%. According to FY 2020 numbers, the median annualized award size is $153,800 and the average duration of an award is 2.9 years.

In 2022 the NSF has started funding Open Source Software as part of their Pathways to Enable Open-Source Ecosystems (POSE) program.

Timeline

Pre–World War II

Although the federal government had established nearly 40 scientific organizations between 1910 and 1940, the US relied upon a primarily laissez-faire approach to scientific research and development. Academic research in science and engineering occasionally received federal funding. Within University laboratories, almost all support came from private contributions and charitable foundations. In industrial laboratories, the concentration of workers and funding (some through military and government programs as a result of Roosevelt's New Deal) would eventually raise concern during the wartime period. In particular, concerns were raised that industry laboratories were largely allowed full patent rights of technologies developed with federal funds. These concerns, in part, led to efforts like Senator Harley M. Kilgore's "Science Mobilization Act".

1940–49

Amidst growing awareness that US military capability depended on strength in science and engineering, Congress considered several proposals to support research in these fields. Separately, President Franklin D. Roosevelt sponsored creation of organizations to coordinate federal funding of science for war, including the National Defense Research Committee and the Office of Scientific Research and Development (OSRD) both from 1941 to 1947. Despite broad agreement over the principle of federal support for science, working out a consensus on how to organize and manage it required five years. The five-year political debate over the creation of a national scientific agency has been a topic for academic study, understood from a variety of perspectives. Themes include disagreements over administrative structure, patents and inclusion of social sciences, a populist-versus-scientist dispute, as well as the roles of political parties, Congress, and President Truman.

Commonly, this debate is characterized by the conflict between New Deal Senator Harley M. Kilgore and OSRD head Vannevar Bush. Narratives about the National Science Foundation prior to the 1970s typically concentrated on Vannevar Bush and his 1945 publication Science—The Endless Frontier. In this report, Vannevar Bush, then head of the Office of Scientific Research and Development which began the Manhattan Project, addressed plans for the postwar years to further foster government commitment to science and technology. Issued to President Harry S. Truman in July 1945, the report made a strong case for federally-funded scientific research, arguing that the nation would reap rich dividends in the form of better health care, a more vigorous economy, and a stronger national defense. It proposed creating a new federal agency, the National Research Foundation.

The NSF first appeared as a comprehensive New Deal Policy proposed by Sen. Harley Kilgore of West Virginia. In 1942, Senator Kilgore introduced the "Science Mobilization Act" (S. 1297), which did not pass. Perceiving organizational chaos, elitism, over-concentration of funds in elite universities, and lack of incentives for socially applicable research, Kilgore envisioned a comprehensive and centralized research body supporting basic and applied research which would be controlled by members of the public and civil servants rather than scientific experts. The public would own the rights to all patents funded by public monies and research monies would be equitably spread across universities. Kilgore's supporters included non-elite universities, small businesses, and the Budget Bureau. His proposals received mixed support.

Vannevar Bush opposed Kilgore, preferring science policy driven by experts and scientists rather than public and civil servants. Bush was concerned that public interests would politicize science, and believed that scientists would be the best judges of the direction and needs of their field. While Bush and Kilgore both agreed on the need for a national science policy, Bush maintained that scientists should continue to own the research results and patents, wanted project selection limited to scientists, and focused support on basic research, not the social sciences, leaving the market to support applied projects.

Sociologist Daniel Kleinman divides the debate into three broad legislative attempts. The first attempt consisted of the 1945 Magnuson bill (S. 1285), the 1945 Science and Technology Mobilization Bill, a 1945 compromise bill (S. 1720), a 1946 compromise bill (S. 1850), and the Mills Bill (H.B. 6448). The Magnuson bill was sponsored by Senator Warren Magnuson and drafted by the OSRD, headed by Vannevar Bush. The Science and Technology Mobilization bill was promoted by Harley Kilgore. The bills called for the creation of a centralized science agency, but differed in governance and research supported. The second attempt, in 1947, included Senator H. Alexander Smith's bill S. 526, and Senator Elbert Thomas's bill S. 525. The Smith bill reflected ideas of Vannevar Bush, while the Thomas bill was identical to the previous year's compromise bill (S. 1850).

After amendments, the Smith bill made it to President Truman's desk, but it was vetoed. Truman wrote that regrettably, the proposed agency would have been "divorced from control by the people to an extent that implies a distinct lack of faith in the democratic process". The third attempt began with the introduction of S. 2385 in 1948. This was a compromise bill cosponsored by Smith and Kilgore, and Bush aide John Teeter had contributed in the drafting process. In 1949, S. 247 was introduced by the same group of senators behind S. 2385, marking the fourth and final effort to establish a national science agency. Essentially identical to S. 2385, S. 247 passed the Senate and the House with a few amendments. It was signed by President Truman on May 10, 1950. Kleinman points out that the final NSF bill closely resembles Vannevar Bush's proposals.

1950–59

In 1950 Harry S. Truman signed Public Law 507, or 42 U.S.C. 16 creating the National Science Foundation. which provided for a National Science Board of twenty-four part-time members. In 1951 Truman nominated Alan T. Waterman, chief scientist at the Office of Naval Research, to become the first Director.

With the Korean War underway, the agency's initial budget was just $151,000 for 9 months. After moving its administrative offices twice, NSF began its first full year of operations with an appropriation from Congress of $3.5 million, far less the almost $33.5 million requested with which 28 research grants were awarded.

After the 1957 Soviet Union orbited Sputnik 1, the first ever human-made satellite, national self-appraisal questioned American education, scientific, technical and industrial strength and Congress increased the NSF appropriation for 1958 to $40 million.

In 1958 the NSF selected Kitt Peak, near Tucson, Arizona, as the site of the first national observatory, that would give any astronomer unprecedented access to state-of-the-art telescopes; previously major research telescopes were privately funded, available only to astronomers who taught at the universities that ran them. The idea expanded to encompass the National Optical Astronomy Observatory, the National Radio Astronomy Observatory, the National Solar Observatory, the Gemini Observatory and the Arecibo Observatory, all of which are funded in whole or in part by NSF. The NSF's astronomy program forged a close working relationship with NASA, also founded in 1958, in that the NSF provides virtually all the U.S. federal support for ground-based astronomy, while NASA's responsibility is the U.S. effort in space-based astronomy.

In 1959 the U.S. and other nations concluded the Antarctic Treaty reserving Antarctica for peaceful and scientific research, and a presidential directive gave the NSF responsibility for virtually all U.S. Antarctic operations and research in form of the United States Antarctic Program.

1960–69

In 1963, President John F. Kennedy appointed Leland John Haworth as the second director of the NSF. During the 1960s, the impact of the Sputnik Crisis spurred international competition in science and technology and accelerated NSF growth. The NSF initiated a number of programs that support institution-wide research during this decade including the Graduate Science Facilities program (started in 1960), Institutional Grants for Science (started in 1961), and Science Development Grants, better known as Centers of Excellence program (started in 1964). Notable projects conducted during this decade include creation of the National Center for Atmospheric Research (1960), creation of the Division of Environmental Sciences (1965), deep sea exploration endeavors Project Mohole (1961) and the Deep Sea Drilling Project (1968–1983), the Ecosystems Analysis Program (1969), and ownership of the Arecibo Observatory (1969). In 1969, Franklin Long was tentatively selected to take over directorship of the NSF. His nomination caused some controversy due to his opposition to the current administration's antiballistic missile program and was ultimately rejected by President Richard Nixon. William D. McElroy instead took over as the third director of the NSF in 1969. By 1968, the NSF budget had reached nearly $500 million.

1970–79

In 1972 the NSF took over management of twelve interdisciplinary materials research laboratories from the Defense Department's Advanced Research Projects Agency (DARPA). These university-based laboratories had taken a more integrated approach than did most academic departments at the time, encouraging physicists, chemists, engineers, and metallurgists to cross departmental boundaries and use systems approaches to attack complex problems of materials synthesis or processing. The NSF expanded these laboratories into a nationwide network of Materials Research Science and Engineering Centers. In 1972 the NSF launched the biennial "Science & Engineering Indicators" report to the US president and Congress, as required by the NSF Act of 1950. In 1977 the first interconnection of unrelated networks was developed, run by DARPA.

1980–89

During this decade, increasing NSF involvement lead to a three-tiered system of internetworks managed by a mix of universities, nonprofit organizations, and government agencies. By the mid-1980s, primary financial support for the growing project was assumed by the NSF. In 1983, NSF budget topped $1 billion for the first time. Major increases in the nation's research budget were proposed as "the country recognizes the importance of research in science and technology, and education". The U.S. Antarctic Program was taken out of the NSF appropriation now requiring a separate appropriation. The NSF received more than 27,000 proposals and funded more than 12,000 of them in 1983. In 1985, the NSF delivered ozone sensors, along with balloons and helium, to researchers at the South Pole so they can measure stratospheric ozone loss. This was in response to findings earlier that year, indicating a steep drop in ozone over a period of several years. The Internet project continued, now known as NSFNET.

1990–99

In 1990 the NSF's appropriation passed $2 billion for the first time. NSF funded the development of several curricula based on the NCTM standards, devised by the National Council of Teachers of Mathematics. These standards were widely adopted by school districts during the subsequent decade. However, in what newspapers such as the Wall Street Journal called the "math wars", organizations such as Mathematically Correct complained that some elementary texts based on the standards, including Mathland, had almost entirely abandoned any instruction of traditional arithmetic in favor of cutting, coloring, pasting, and writing. During that debate, NSF was both lauded and criticized for favoring the standards.

In 1991 the NSFNET acceptable use policy was altered to allow commercial traffic. By 1995, with private, commercial market thriving, NSF decommissioned the NSFNET, allowing for public use of the Internet. In 1993 students and staff at the NSF-supported National Center for Supercomputing Applications (NCSA) at the University of Illinois, Urbana-Champaign, developed Mosaic, the first freely available browser to allow World Wide Web pages that include both graphics and text. Within 18 months, NCSA Mosaic becomes the Web browser of choice for more than a million users, and sets off an exponential growth in the number of Web users. In 1994 NSF, together with DARPA and NASA, launched the Digital Library Initiative. One of the first six grants went to Stanford University, where two graduate students, Larry Page and Sergey Brin, began to develop a search engine that used the links between Web pages as a ranking method, which they later commercialized under the name Google.

In 1996 NSF-funded research established beyond doubt that the chemistry of the atmosphere above Antarctica was grossly abnormal and that levels of key chlorine compounds are greatly elevated. During two months of intense work, NSF researchers learned most of what is known about the ozone hole.

In 1998 two independent teams of NSF-supported astronomers discovered that the expansion of the universe was actually speeding up, as if some previously unknown force, now known as dark energy, is driving the galaxies apart at an ever-increasing rate.

Since passage of the Small Business Technology Transfer Act of 1992 (Public Law 102–564, Title II), NSF has been required to reserve 0.3% of its extramural research budget for Small Business Technology Transfer awards, and 2.8% of its R&D budget for small business innovation research.

2000–09

NSF joined with other federal agencies in the National Nanotechnology Initiative, dedicated to the understanding and control of matter at the atomic and molecular scale. NSF's roughly $300 million annual investment in nanotechnology research was still one of the largest in the 23-agency initiative. In 2001, NSF's appropriation passed $4 billion. The NSF's "Survey of Public Attitudes Toward and Understanding of Science and Technology" revealed that the public had a positive attitude toward science, but a poor understanding of it. During 2004–5 NSF sent "rapid response" research teams to investigate the aftermath of the Indian Ocean tsunami disaster and Hurricane Katrina. An NSF-funded engineering team helped uncover why the levees failed in New Orleans. In 2005, NSF's budget stood at $5.6 billion, in 2006 it stood at $5.91 billion for the 2007 fiscal year (October 1, 2006, through September 30, 2007), and in 2007 NSF requested $6.43 billion for FY 2008.

2010–19

President Obama requested $7.373 billion for fiscal year 2013. Due to the October 1, 2013 shutdown of the Federal Government, and NSF's lapse in funding, their website was down "until further notice", but was brought back online after the US government passed their budget. In 2014, NSF awarded rapid response grants to study a chemical spill that contaminated the drinking water of about 300,000 West Virginia residents. In early 2018, it was announced that Trump would cut NSF Research Funding by 30% but quickly rescinded this due to backlash. As of May 2018, Heather Wilson, the secretary of the Air Force, signed that letter of intent with the director of NSF initiating partnership for the research related to space operations and Geosciences, advanced material sciences, information and data sciences, and workforce and processes.

Grants and the merit review process

A grant proposal which the National Science Foundation chose to fund

The NSF seeks to fulfill its mission chiefly by issuing competitive, limited-term grants in response to specific proposals from the research community and establishing cooperative agreements with research organizations. It does not operate its own laboratories, unlike other federal research agencies, notable examples being NASA and the National Institutes of Health (NIH). The NSF uses four main mechanisms to communicate funding opportunities and generate proposals: dear colleague letters, program descriptions, program announcements, and program solicitations.

The NSF receives over 50,000 such proposals each year, and funds about 10,000 of them. Those funded are typically projects that are ranked highest in a 'merit review' process, the current version of which was introduced in 1997. Reviews are carried out by ad hoc reviewers and panels of independent scientists, engineers, and educators who are experts in the relevant fields of study, and who are selected by the NSF with particular attention to avoiding conflicts of interest. For example, reviewers cannot work at the NSF itself, nor for the institution that employs the proposing researchers. All proposal evaluations are confidential: the proposing researchers may see them, but they do not see the names of the reviewers.

The first merit review criterion is 'intellectual merit', the second is that of the 'broader societal impact' of the proposed research; the latter reflects a broader global trend for funding agencies to demand evidence of research 'impact' and has been met with opposition from the scientific and policy communities since its inception in 1997. In June 2010, the National Science Board (NSB), the governing body for NSF and science advisers to both the legislative and executive branches, convened a 'Task Force on Merit Review' to determine "how well the current Merit Review criteria used by the NSF to evaluate all proposals were serving the agency." The task force reinforced its support for both criteria as appropriate for the goals and aims of the agency and published a revised version of the merit review criteria in its 2012 report, to clarify and improve the function of the criteria. However, both criteria already had been mandated for all NSF merit review procedures in the 2010 re-authorization of the America COMPETES Act. The Act also includes an emphasis on promoting potentially transformative research, a phrase which has been included in the most recent incarnation of the 'merit review' criteria.

Most NSF grants go to individuals or small groups of investigators, who carry out research at their home campuses. Other grants provide funding for mid-scale research centers, instruments, and facilities that serve researchers from many institutions. Still, others fund national-scale facilities that are shared by the research community as a whole. Examples of national facilities include the NSF's national observatories, with their giant optical and radio telescopes; its Antarctic research sites; its high-end computer facilities and ultra-high-speed network connections; the ships and submersibles used for ocean research; and its gravitational wave observatories.

In addition to researchers and research facilities, NSF grants also support science, engineering and mathematics education from pre-K through graduate school. Undergraduates can receive funding through Research Experiences for Undergraduates summer programs. Graduate students are supported through Integrative Graduate Education Research Traineeships (IGERT) and Alliance for Graduate Education and the Professoriate (AGEP) programs and through the Graduate Research Fellowships, NSF-GRF. K–12 and some community college instructors are eligible to participate in compensated Research Experiences for Teachers programs. In addition, an early career-development program (CAREER) supports teacher-scholars that most effectively integrate research and education within the mission of their organization, as a foundation for a lifetime of integrated contributions.

Scope and organization

National Science Foundation's former headquarters in Arlington County, Virginia; in 2017, the foundation relocated to Alexandria, Virginia

The NSF is broadly organized into four offices, seven directorates, and the National Science Board. It employs about 2,100 people in permanent, temporary and contractual positions at its headquarters in Alexandria, Virginia. Prior to 2017, its headquarters were located in Arlington, Virginia.

In addition to around 1,400 permanent employees and the staffs of the NSB office and the Office of the Inspector General, NSF's workforce includes some 200 scientists on temporary duty and 450 contract workers. Scientists from research institutions can join the NSF as temporary program directors, called "rotators", overseeing the merit review process and searching for new funding opportunities. These assignments typically last 1–2 years, but may extend to 4. The NSF also offers contracting opportunities. As of May 2018, the NSF has 53 existing contracts.

Offices

• Office of the Director
• Office of the Inspector General
• Office of Budget, Finance, and Award Management
• Office of Information & Resource Management
• Office of the Chief Information Officer

The NSF also supports research through several offices within the Office of the Director, including the Office of Integrative Activities, and Office of International Science and Engineering.

Research directorates

The NSF organizes its research and education support through eight directorates, each encompassing several disciplines:

• Biological Sciences (molecular, cellular, and organismal biology, environmental science)
• Computer and Information Science and Engineering (theoretical computer science, fundamental hardware and software, systems and networking, and artificial intelligence)
• Engineering (bioengineering, environmental systems, civil and mechanical systems, chemical and transport systems, electrical and communications systems, and design and manufacturing)
• Geosciences (geological, atmospheric and ocean sciences)
• Mathematical and Physical Sciences (mathematics, astronomy, physics, chemistry and materials science)
• Social, Behavioral and Economic Sciences (neuroscience, management, psychology, sociology, anthropology, linguistics, science of science policy and economics)
• STEM Education and Human Resources (science, technology, engineering and mathematics education at every level)

An eighth directorate, the Directorate for Technology, Innovation and Partnerships (TIP), was created in 2022 to accelerate the transition of basic research into real world impact. It has a primary goal of the support of use-inspired research and the translation of research results to the market and society.

Overseas sites

Prior to October 2018, NSF maintained three overseas offices to promote collaboration between the science and engineering communities of the United States and other continents' scientific communities:

• Brussels for Europe, formerly based in Paris (established 1984; relocated to Brussels in 2015)
• Tokyo for East Asia, except China (established 1960)
• Beijing for China (established 2006)

All three overseas offices were shut down in October 2018, to reflect the agency's move to a more nimble international posture. Rather than maintain dedicated offices, NSF will dispatch small teams to specific international institutions. Teams may work for up to a week on-site to evaluate research and explore collaborations with the institution.

Crosscutting programs

In addition to the research it funds in specific disciplines, the NSF has launched a number of projects that coordinate the efforts of experts in many disciplines, which often involve collaborations with other U.S. federal agencies. Examples include initiatives in:

• Nanotechnology
• The science of learning
• Digital libraries
• The ecology of infectious diseases

National Center for Science and Engineering Statistics

NSF's National Center for Science and Engineering Statistics (NCSES) gathers data from surveys and partnerships with other agencies to offer official data on the American science and engineering workforce, graduates of advanced U.S. science and engineering programs, and R&D expenditures by U.S. industry. NCSES is one of the principal U.S. statistical agencies. It is a part of the NSF's Social, Behavioral and Economic Sciences Directorate (SBE).

Criticism

In May 2011, Republican Senator Tom Coburn released a 73-page report, "National Science Foundation: Under the Microscope", receiving immediate attention from such media outlets as The New York Times, Fox News, and MSNBC. The report found fault with various research projects and was critical of the social sciences. It started a controversy about political bias and a Congressional Inquiry into federally sponsored research. In 2014, Republicans proposed a bill to limit the NSF Board's authority in grant-writing.

In 2013, the NSF had funded the work of Mark Carey at University of Oregon with a $412,930 grant, which included a study concerning gender in glaciological research. After its January 2016 release, the NSF drew criticism for alleged misuse of funding.

Some historians of science have argued that the National Science Foundation Act of 1950 was an unsatisfactory compromise between too many clashing visions of the purpose and scope of the federal government. The NSF was certainly not the primary government agency for the funding of basic science, as its supporters had originally envisioned in the aftermath of World War II. By 1950, support for major areas of research had already become dominated by specialized agencies such as the National Institutes of Health (medical research) and the U.S. Atomic Energy Commission (nuclear and particle physics). That pattern would continue after 1957 when U.S. anxiety over the launch of Sputnik led to the creation of the National Aeronautics and Space Administration (space science) and the Defense Advanced Research Projects Agency (defense-related research).

Concave function

From Wikipedia, the free encyclopedia
https://en.wikipedia.org/wiki/Concave_function

In mathematics, a concave function is one for which the value at any convex combination of elements in the domain is greater than or equal to the convex combination of the values at the endpoints. Equivalently, a concave function is any function for which the hypograph is convex. The class of concave functions is in a sense the opposite of the class of convex functions. A concave function is also synonymously called concave downwards, concave down, convex upwards, convex cap, or upper convex.

Definition

A real-valued function ${\displaystyle f}$ on an interval (or, more generally, a convex set in vector space) is said to be concave if, for any ${\displaystyle x}$ and ${\displaystyle y}$ in the interval and for any ${\displaystyle \alpha \in [0,1]}$,

${\displaystyle f((1-\alpha )x+\alpha y)\ge (1-\alpha )f(x)+\alpha f(y)}$

A function is called strictly concave if

${\displaystyle f((1-\alpha )x+\alpha y)>(1-\alpha )f(x)+\alpha f(y)}$

for any ${\displaystyle \alpha \in (0,1)}$ and ${\displaystyle x\ne y}$.

For a function ${\displaystyle f:\mathbb{R}\to \mathbb{R}}$, this second definition merely states that for every ${\displaystyle z}$ strictly between ${\displaystyle x}$ and ${\displaystyle y}$, the point ${\displaystyle (z,f(z))}$ on the graph of ${\displaystyle f}$ is above the straight line joining the points ${\displaystyle (x,f(x))}$ and ${\displaystyle (y,f(y))}$.

A function ${\displaystyle f}$ is quasiconcave if the upper contour sets of the function ${\displaystyle S(a)=\{x:f(x)\ge a\}}$ are convex sets.

Properties

A cubic function is concave (left half) when its first derivative (red) is monotonically decreasing i.e. its second derivative (orange) is negative, and convex (right half) when its first derivative is monotonically increasing i.e. its second derivative is positive

Functions of a single variable

1. A differentiable function f is (strictly) concave on an interval if and only if its derivative function f ′ is (strictly) monotonically decreasing on that interval, that is, a concave function has a non-increasing (decreasing) slope.
2. Points where concavity changes (between concave and convex) are inflection points.
3. If f is twice-differentiable, then f is concave if and only if f ′′ is non-positive (or, informally, if the "acceleration" is non-positive). If f ′′ is negative then f is strictly concave, but the converse is not true, as shown by f(x) = −x⁴.
4. If f is concave and differentiable, then it is bounded above by its first-order Taylor approximation: $${\displaystyle f(y)\le f(x)+f^{\prime }(x)[y-x]}$$
5. A Lebesgue measurable function on an interval C is concave if and only if it is midpoint concave, that is, for any x and y in C $${\displaystyle f\left(\frac{x+y}{2}\right)\ge \frac{f(x)+f(y)}{2}}$$
6. If a function f is concave, and f(0) ≥ 0, then f is subadditive on ${\displaystyle [0,\mathrm{\infty })}$. Proof:
   • Since f is concave and 1 ≥ t ≥ 0, letting y = 0 we have $${\displaystyle f(tx)=f(tx+(1-t)\cdot 0)\ge tf(x)+(1-t)f(0)\ge tf(x).}$$
   • For ${\displaystyle a,b\in [0,\mathrm{\infty })}$: $${\displaystyle f(a)+f(b)=f\left((a+b)\frac{a}{a+b}\right)+f\left((a+b)\frac{b}{a+b}\right)\ge \frac{a}{a+b}f(a+b)+\frac{b}{a+b}f(a+b)=f(a+b)}$$

Functions of n variables

1. A function f is concave over a convex set if and only if the function −f is a convex function over the set.
2. The sum of two concave functions is itself concave and so is the pointwise minimum of two concave functions, i.e. the set of concave functions on a given domain form a semifield.
3. Near a strict local maximum in the interior of the domain of a function, the function must be concave; as a partial converse, if the derivative of a strictly concave function is zero at some point, then that point is a local maximum.
4. Any local maximum of a concave function is also a global maximum. A strictly concave function will have at most one global maximum.

Examples

• The functions ${\displaystyle f(x)=-x^2}$ and ${\displaystyle g(x)=\sqrt{x}}$ are concave on their domains, as their second derivatives ${\displaystyle f^{″}(x)=-2}$ and $g^{″}(x)=-\frac{1}{4x^{3/2}}$ are always negative.
• The logarithm function ${\displaystyle f(x)=\log x}$ is concave on its domain ${\displaystyle (0,\mathrm{\infty })}$, as its derivative ${\displaystyle \frac{1}{x}}$ is a strictly decreasing function.
• Any affine function ${\displaystyle f(x)=ax+b}$ is both concave and convex, but neither strictly-concave nor strictly-convex.
• The sine function is concave on the interval ${\displaystyle [0,\pi ]}$.
• The function ${\displaystyle f(B)=\log |B|}$, where ${\displaystyle |B|}$ is the determinant of a nonnegative-definite matrix B, is concave.

Applications

Rays bending in the computation of radiowave attenuation in the atmosphere involve concave functions.

In expected utility theory for choice under uncertainty, cardinal utility functions of risk averse decision makers are concave.

In microeconomic theory, production functions are usually assumed to be concave over some or all of their domains, resulting in diminishing returns to input factors.

In Thermodynamics and Information Theory, Entropy is a concave function. In the case of thermodynamic entropy, without phase transition, entropy as a function of extensive variables is strictly concave. If the system can undergo phase transition, if it is allowed to split into two subsystems of different phase (phase separation, e.g. boiling), the entropy-maximal parameters of the subsystems will result in a combined entropy precisely on the straight line between the two phases. This means that the "Effective Entropy" of a system with phase transition is the convex envelope of entropy without phase separation; therefore, the entropy of a system including phase separation will be non-strictly concave.
