Open data is the idea that some data should be available to everyone to use and republish as they wish, without restrictions from copyright, patents or other mechanisms of control. The goals of the open-source data movement are similar to those of other "open" movements such as open-source software, open content, open education, open educational resources, open government, open knowledge, open access, open science, the open web. Paradoxically, the growth of the open data movement is paralleled by a rise in intellectual property rights; the philosophy behind open data has been long established, but the term "open data" itself is recent, gaining popularity with the rise of the Internet and World Wide Web and with the launch of open-data government initiatives such as Data.gov, Data.gov.uk and Data.gov.in. Open data, can be linked data. One of the most important forms of open data is open government data, a form of open data created by ruling government institutions. Open government data's importance is borne from it being a part of citizens' everyday lives, down to the most routine/mundane tasks that are far removed from government.
The concept of open data is not new. One definition is the Open Definition which can be summarized in the statement that "A piece of data is open if anyone is free to use and redistribute it – subject only, at most, to the requirement to attribute and/or share-alike." Other definitions, including the Open Data Institute's "Open data is data that anyone can access, use or share", have an accessible short version of the definition but refer to the formal definition. Open data may include non-textual material such as maps, connectomes, chemical compounds and scientific formulae, medical data and practice and biodiversity. Problems arise because these are commercially valuable or can be aggregated into works of value. Access to, or re-use of, the data is controlled by organisations, both private. Control may be through access restrictions, copyright and charges for access or re-use. Advocates of open data argue that these restrictions are against the common good and that these data should be made available without restriction or fee.
In addition, it is important that the data are re-usable without requiring further permission, though the types of re-use may be controlled by a license. A typical depiction of the need for open data: Numerous scientists have pointed out the irony that right at the historical moment when we have the technologies to permit worldwide availability and distributed process of scientific data, broadening collaboration and accelerating the pace and depth of discovery... we are busy locking up that data and preventing the use of correspondingly advanced technologies on knowledge. Creators of data do not consider the need to state the conditions of ownership, licensing and re-use. For example, many scientists do not regard the published data arising from their work to be theirs to control and consider the act of publication in a journal to be an implicit release of data into the commons. However, the lack of a license makes it difficult to determine the status of a data set and may restrict the use of data offered in an "Open" spirit.
Because of this uncertainty it is possible for public or private organizations to aggregate said data, protect it with copyright and resell it. The issue of indigenous knowledge poses a great challenge in terms of capturing and distribution. Many societies in third-world countries lack the technicality processes of managing the IK. At his presentation at the XML 2005 conference, Connolly displayed these two quotations regarding open data: "I want my data back." "I've long believed that customers of any application own the data they enter into it." Open data can come from any source. This section lists some of the fields; the concept of open access to scientific data was institutionally established with the formation of the World Data Center system, in preparation for the International Geophysical Year of 1957–1958. The International Council of Scientific Unions oversees several World Data Centres with the mandate to minimize the risk of data loss and to maximize data accessibility. While the open-science-data movement long predates the Internet, the availability of fast, ubiquitous networking has changed the context of Open science data, since publishing or obtaining data has become much less expensive and time-consuming.
The Human Genome Project was a major initiative. It was built upon the so-called Bermuda Principles, stipulating that: "All human genomic sequence information should be available and in the public domain in order to encourage research and development and to maximise its benefit to society'. More recent initiatives such as the Structural Genomics Consortium have illustrated that the open data approach can be used productively within the context of industrial R&D. In 2004, the Science Ministers of all nations of the Organisation for Economic Co-operation and Development, which includes most developed countries of the world, signed a declaration which states that all publicly funded archive data should be made publicly available. Following a request and an intense discussion with data-pr
Eric Michael Garcetti is an American politician serving as the 42nd and current Mayor of Los Angeles since 2013.

In 2005, Garcetti helped, he authored two of the nation's most far-reaching municipal green building ordinances: the first requires all city buildings to be built to the LEED-certified standard, the second mandates that all commercial buildings of more than 50,000 sq ft in Los Angeles be built to a LEED standard. He supported changes in the city's landscape ordinance and plumbing codes to promote water conservation. In July 2010, Garcetti council president, weakened a 2009 lawn watering ordinance, allowing watering three days per week instead of two; the ordinance restricting watering to two days a week had been passed 13 months earlier by Mayor Antonio Villaraigosa. While it helped the city cut its water use and cope with ongoing drought, the measure was unpopular and was accused of causing pressure fluctuations and water main breaks. A Los Angeles Times editorial said that the city council's changes to the watering ordinance was a "death knell for one of the best collective environmental efforts made by the citizens of Los Angeles".
Garcetti worked to have Historic Filipinotown desingated a Preserve America Community. He championed renovating the Hollywood Palladium by Live Nation Entertainment, at risk of being demolished, he has faced public scrutiny f
The United States of America known as the United States or America, is a country composed of 50 states, a federal district, five major self-governing territories, various possessions. At 3.8 million square miles, the United States is the world's third or fourth largest country by total area and is smaller than the entire continent of Europe's 3.9 million square miles. With a population of over 327 million people, the U. S. is the third most populous country. The capital is Washington, D. C. and the largest city by population is New York City. Forty-eight states and the capital's federal district are contiguous in North America between Canada and Mexico; the State of Alaska is in the northwest corner of North America, bordered by Canada to the east and across the Bering Strait from Russia to the west. The State of Hawaii is an archipelago in the mid-Pacific Ocean; the U. S. territories are scattered about the Pacific Ocean and the Caribbean Sea, stretching across nine official time zones. The diverse geography and wildlife of the United States make it one of the world's 17 megadiverse countries.
Paleo-Indians migrated from Siberia to the North American mainland at least 12,000 years ago. European colonization began in the 16th century; the United States emerged from the thirteen British colonies established along the East Coast. Numerous disputes between Great Britain and the colonies following the French and Indian War led to the American Revolution, which began in 1775, the subsequent Declaration of Independence in 1776; the war ended in 1783 with the United States becoming the first country to gain independence from a European power. The current constitution was adopted in 1788, with the first ten amendments, collectively named the Bill of Rights, being ratified in 1791 to guarantee many fundamental civil liberties; the United States embarked on a vigorous expansion across North America throughout the 19th century, acquiring new territories, displacing Native American tribes, admitting new states until it spanned the continent by 1848. During the second half of the 19th century, the Civil War led to the abolition of slavery.
By the end of the century, the United States had extended into the Pacific Ocean, its economy, driven in large part by the Industrial Revolution, began to soar. The Spanish–American War and World War I confirmed the country's status as a global military power; the United States emerged from World War II as a global superpower, the first country to develop nuclear weapons, the only country to use them in warfare, a permanent member of the United Nations Security Council. Sweeping civil rights legislation, notably the Civil Rights Act of 1964, the Voting Rights Act of 1965 and the Fair Housing Act of 1968, outlawed discrimination based on race or color. During the Cold War, the United States and the Soviet Union competed in the Space Race, culminating with the 1969 U. S. Moon landing; the end of the Cold War and the collapse of the Soviet Union in 1991 left the United States as the world's sole superpower. The United States is the world's oldest surviving federation, it is a representative democracy.
The United States is a founding member of the United Nations, World Bank, International Monetary Fund, Organization of American States, other international organizations. The United States is a developed country, with the world's largest economy by nominal GDP and second-largest economy by PPP, accounting for a quarter of global GDP; the U. S. economy is post-industrial, characterized by the dominance of services and knowledge-based activities, although the manufacturing sector remains the second-largest in the world. The United States is the world's largest importer and the second largest exporter of goods, by value. Although its population is only 4.3% of the world total, the U. S. holds 31% of the total wealth in the world, the largest share of global wealth concentrated in a single country. Despite wide income and wealth disparities, the United States continues to rank high in measures of socioeconomic performance, including average wage, human development, per capita GDP, worker productivity.
The United States is the foremost military power in the world, making up a third of global military spending, is a leading political and scientific force internationally. In 1507, the German cartographer Martin Waldseemüller produced a world map on which he named the lands of the Western Hemisphere America in honor of the Italian explorer and cartographer Amerigo Vespucci; the first documentary evidence of the phrase "United States of America" is from a letter dated January 2, 1776, written by Stephen Moylan, Esq. to George Washington's aide-de-camp and Muster-Master General of the Continental Army, Lt. Col. Joseph Reed. Moylan expressed his wish to go "with full and ample powers from the United States of America to Spain" to seek assistance in the revolutionary war effort; the first known publication of the phrase "United States of America" was in an anonymous essay in The Virginia Gazette newspaper in Williamsburg, Virginia, on April 6, 1776. The second draft of the Articles of Confederation, prepared by John Dickinson and completed by June 17, 1776, at the latest, declared "The name of this Confederation shall be the'United States of America'".
The final version of the Articles sent to the states for ratification in late 1777 contains the sentence "The Stile of this Confederacy shall be'The United States of America'". In June 1776, Thomas Jefferson wrote the phrase "UNITED STATES OF AMERICA" in all capitalized letters in the headline of his "original Rough draught" of the Declaration of Independence; this draft of the document did not surface unti
The chairman is the highest officer of an organized group such as a board, a committee, or a deliberative assembly. The person holding the office is elected or appointed by the members of the group, the chairman presides over meetings of the assembled group and conducts its business in an orderly fashion. In some organizations, the chairman position is called president, in others, where a board appoints a president, the two different terms are used for distinctly different positions. Other terms sometimes used for the office and its holder include chair, chairwoman, presiding officer, moderator and convenor; the chairman of a parliamentary chamber is called the speaker. The term chair is sometimes used in lieu of chairman, in response to criticisms that using chairman is sexist, it is used today, has been used as a substitute for chairman since the middle of the 17th century, with its earliest citation in the Oxford English Dictionary dated 1658–1659, only four years after the first citation for chairman.
Major dictionaries state that the word derives from a person. A 1994 Canadian study found the Toronto Star newspaper referring to most presiding men as "chairman", to most presiding women as "chairperson" or as "chairwoman"; the Chronicle of Higher Education uses "chairman" for men and "chairperson" for women. An analysis of the British National Corpus found chairman used 1,142 times, chairperson 130 times and chairwoman 68 times; the National Association of Parliamentarians adopted a resolution in 1975 discouraging the use of “chairperson” and rescinded it in 2017. The Wall Street Journal, The New York Times and United Press International all use "chairwoman" or "chairman" when referring to women, forbid use of "chair" or of "chairperson" except in direct quotations. In World Schools Style debating, male chairs are called "Mr. Chairman" and female chairs are called "Madame Chair"; the FranklinCovey Style Guide for Business and Technical Communication, as well as the American Psychological Association style guide, advocate using "chair" or "chairperson", rather than "chairman".
The Oxford Dictionary of American Usage and Style suggests that the gender-neutral forms are gaining ground. It advocates using "chair" to refer both to women; the Telegraph style guide bans the use of both "Chair" and "Chairperson" on the basis that "Chairman" is correct English. The word chair can refer to the place from which the holder of the office presides, whether on a chair, at a lectern, or elsewhere. During meetings, the person presiding is said to be "in the chair" and is referred to as "the chair". Parliamentary procedure requires that members address the "chair" as "Mr. Chairman" rather than using a name – one of many customs intended to maintain the presiding officer's impartiality and to ensure an objective and impersonal approach. In the United States, the presiding officer of the lower house of a legislative body, such as the House of Representatives, is titled the Speaker, while the upper house, such as the Senate, is chaired by a President. In his 1992 State of the Union address, then-U.
S. President George H. W. Bush used "chairman" for men and "chair" for women. In the British music hall tradition, the Chairman was the master of ceremonies who announced the performances and was responsible for controlling any rowdy elements in the audience; the role was popularised on British TV in the 1960s and 1970s by Leonard Sachs, the Chairman on the variety show The Good Old Days."Chairman" as a quasi-title gained particular resonance when socialist states from 1917 onward shunned more traditional leadership labels and stressed the collective control of soviets by beginning to refer to executive figureheads as "Chairman of the X Committee". Vladimir Lenin, for example functioned as the head of Soviet Russia not as tsar or as president but in roles such as "Chairman of the Council of People's Commissars of the Russian SFSR". Note in particular the popular standard method for referring to Mao Zedong: "Chairman Mao". In addition to the administrative or executive duties in organizations, the chairman has the duties of presiding over meetings.
Such duties at meetings include: Calling the meeting to order Determining if a quorum is present Announcing the items on the order of business or agenda as they come up Recognition of members to have the floor Enforcing the rules of the group Putting questions to a vote Adjourning the meetingWhile presiding, the chairman should remain impartial and not interrupt a speaker if the speaker has the floor and is following the rules of the group. In committees or small boards, the chairman votes along with the other members. However, in assemblies or larger boards, the chairman should vote only when it can affect the result. At a meeting, the chairman only has one vote; the powers of the chairman vary across organizations. In some organizations the chairman has the authority to hire staff and make financial decisions, while in others the chairman only makes recommendations to a board of directors, still others the chairman has no executive powers and is a spokesman for the organization; the amount of power given to the chairman depends on the type of organization, its structure, the rules it has created for itself.
If the chairman exceeds the given authority, engages in misconduct, or fails to perform t
Law is a system of rules that are created and enforced through social or governmental institutions to regulate behavior. It has been defined both as "the Science of Justice" and "the Art of Justice". Law is a system that regulates and ensures that individuals or a community adhere to the will of the state. State-enforced laws can be made by a collective legislature or by a single legislator, resulting in statutes, by the executive through decrees and regulations, or established by judges through precedent in common law jurisdictions. Private individuals can create binding contracts, including arbitration agreements that may elect to accept alternative arbitration to the normal court process; the formation of laws themselves may be influenced by a constitution, written or tacit, the rights encoded therein. The law shapes politics, economics and society in various ways and serves as a mediator of relations between people. A general distinction can be made between civil law jurisdictions, in which a legislature or other central body codifies and consolidates their laws, common law systems, where judge-made precedent is accepted as binding law.
Religious laws played a significant role in settling of secular matters, is still used in some religious communities. Islamic Sharia law is the world's most used religious law, is used as the primary legal system in some countries, such as Iran and Saudi Arabia; the adjudication of the law is divided into two main areas. Criminal law deals with conduct, considered harmful to social order and in which the guilty party may be imprisoned or fined. Civil law deals with the resolution of lawsuits between individuals and/or organizations. Law provides a source of scholarly inquiry into legal history, economic analysis and sociology. Law raises important and complex issues concerning equality and justice. Numerous definitions of law have been put forward over the centuries; the Third New International Dictionary from Merriam-Webster defines law as: "Law is a binding custom or practice of a community. The Dictionary of the History of Ideas published by Scribner's in 1973 defined the concept of law accordingly as: "A legal system is the most explicit, institutionalized, complex mode of regulating human conduct.
At the same time, it plays only one part in the congeries of rules which influence behavior, for social and moral rules of a less institutionalized kind are of great importance." There have been several attempts to produce "a universally acceptable definition of law". In 1972, one source indicated. McCoubrey and White said that the question "what is law?" has no simple answer. Glanville Williams said that the meaning of the word "law" depends on the context in which that word is used, he said that, for example, "early customary law" and "municipal law" were contexts where the word "law" had two different and irreconcilable meanings. Thurman Arnold said that it is obvious that it is impossible to define the word "law" and that it is equally obvious that the struggle to define that word should not be abandoned, it is possible to take the view that there is no need to define the word "law". The history of law links to the development of civilization. Ancient Egyptian law, dating as far back as 3000 BC, contained a civil code, broken into twelve books.
It was based on the concept of Ma'at, characterised by tradition, rhetorical speech, social equality and impartiality. By the 22nd century BC, the ancient Sumerian ruler Ur-Nammu had formulated the first law code, which consisted of casuistic statements. Around 1760 BC, King Hammurabi further developed Babylonian law, by codifying and inscribing it in stone. Hammurabi placed several copies of his law code throughout the kingdom of Babylon as stelae, for the entire public to see; the most intact copy of these stelae was discovered in the 19th century by British Assyriologists, has since been transliterated and translated into various languages, including English, Italian and French. The Old Testament dates back to 1280 BC and takes the form of moral imperatives as recommendations for a good society; the small Greek city-state, ancient Athens, from about the 8th century BC was the first society to be based on broad inclusion of its citizenry, excluding women and the slave class. However, Athens had no legal science or single word for "law", relying instead on the three-way distinction between divine law, human decree and custom.
Yet Ancient Greek law contained major constitutional innovations in the development of democracy. Roman law was influenced by Greek philosophy, but its detailed rules were developed by professional jurists and were sophisticated. Over the centuries between the rise and decline of the Roman Empire, law was adapted to cope with the changing social situations and underwent major codification under Theodosius II and Justinian I. Although codes were replaced by custom and case law during the Dark Ages, Roman law was rediscovered around the 11th century when medieval legal scholars began to research Roman codes and adapt their concepts. Latin legal maxims were compiled for guidance. In medieval England, royal
Alma mater is an allegorical Latin phrase for a university, school, or college that one attended. In US usage it can mean the school from which one graduated; the phrase is variously translated as "nourishing mother", "nursing mother", or "fostering mother", suggesting that a school provides intellectual nourishment to its students. Fine arts will depict educational institutions using a robed woman as a visual metaphor. Before its current usage, alma mater was an honorific title for various Latin mother goddesses Ceres or Cybele, in Catholicism for the Virgin Mary, it entered academic usage when the University of Bologna adopted the motto Alma Mater Studiorum, which describes its heritage as the oldest operating university in the Western world. It is related to alumnus, a term used for a university graduate that means a "nursling" or "one, nourished". Although alma was a common epithet for Ceres, Cybele and other mother goddesses, it was not used in conjunction with mater in classical Latin. In the Oxford Latin Dictionary, the phrase is attributed to Lucretius' De rerum natura, where it is used as an epithet to describe an earth goddess: After the fall of Rome, the term came into Christian liturgical usage in association with the Virgin Mary.
"Alma Redemptoris Mater" is a well-known 11th century antiphon devoted to Mary. The earliest documented use of the term to refer to a university in an English-speaking country is in 1600, when the University of Cambridge printer, John Legate, began using an emblem for the university's press; the device's first-known appearance is on the title-page of William Perkins' A Golden Chain, where the Latin phrase Alma Mater Cantabrigia is inscribed on a pedestal bearing a nude, lactating woman wearing a mural crown. In English etymological reference works, the first university-related usage is cited in 1710, when an academic mother figure is mentioned in a remembrance of Henry More by Richard Ward. Many historic European universities have adopted Alma Mater as part of the Latin translation of their official name; the University of Bologna Latin name, Alma Mater Studiorum, refers to its status as the oldest continuously operating university in the world. Other European universities, such as the Alma Mater Lipsiensis in Leipzig, Germany, or Alma Mater Jagiellonica, have used the expression in conjunction with geographical or foundational characteristics.
At least one, the Alma Mater Europaea in Salzburg, Austria, an international university founded by the European Academy of Sciences and Arts in 2010, uses the term as its official name. In the United States, the College of William & Mary in Williamsburg, has been called the "Alma Mater of the Nation" because of its ties to the country's founding. At Queen's University in Kingston and the University of British Columbia in Vancouver, British Columbia, the main student government is known as the Alma Mater Society; the ancient Roman world had many statues of the Alma Mater, some still extant. Modern sculptures are found in prominent locations on several American university campuses. For example, in the United States: there is a well-known bronze statue of Alma Mater by Daniel Chester French situated on the steps of Columbia University's Low Library. An altarpiece mural in Yale University's Sterling Memorial Library, painted in 1932 by Eugene Savage, depicts the Alma Mater as a bearer of light and truth, standing in the midst of the personified arts and sciences.
Outside the United States, there is an Alma Mater sculpture on the steps of the monumental entrance to the Universidad de La Habana, in Havana, Cuba. The statue was cast in 1919 by Mario Korbel, with Feliciana Villalón Wilson as the inspiration for Alma Mater, it was installed in its current location in 1927, at the direction of architect Raul Otero.

Los Angeles the City of Los Angeles and known by its initials L. A. is the most populous city in California, the second most populous city in the United States, after New York City, the third most populous city in North America. With an estimated population of four million, Los Angeles is the cultural and commercial center of Southern California; the city is known for its Mediterranean climate, ethnic diversity and the entertainment industry, its sprawling metropolis. Los Angeles is the largest city on the West Coast of North America. Los Angeles is in a large basin bounded by the Pacific Ocean on one side and by mountains as high as 10,000 feet on the other; the city proper, which covers about 469 square miles, is the seat of Los Angeles County, the most populated county in the country. Los Angeles is the principal city of the Los Angeles metropolitan area, the second largest in the United States after that of New York City, with a population of 13.1 million. It is part of the Los Angeles-Long Beach combined statistical area the nation's second most populous area with a 2015 estimated population of 18.7 million.
Los Angeles is one of the most substantial economic engines within the United States, with a diverse economy in a broad range of professional and cultural fields. Los Angeles is famous as the home of Hollywood, a major center of the world entertainment industry. A global city, it has been ranked 6th in the Global Cities Index and 9th in the Global Economic Power Index; the Los Angeles metropolitan area has a gross metropolitan product of $1.044 trillion, making it the third-largest in the world, after the Tokyo and New York metropolitan areas. Los Angeles hosted the 1932 and 1984 Summer Olympics and will host the event for a third time in 2028; the city hosted the Miss Universe pageant twice, in 1990 and 2006, was one of 9 American cities to host the 1994 FIFA men's soccer World Cup and one of 8 to host the 1999 FIFA women's soccer World Cup, hosting the final match for both tournaments. Home to the Chumash and Tongva, Los Angeles was claimed by Juan Rodríguez Cabrillo for Spain in 1542 along with the rest of what would become Alta California.
The city was founded on September 4, 1781, by Spanish governor Felipe de Neve. It became a part of Mexico in 1821 following the Mexican War of Independence. In 1848, at the end of the Mexican–American War, Los Angeles and the rest of California were purchased as part of the Treaty of Guadalupe Hidalgo, becoming part of the United States. Los Angeles was incorporated as a municipality on April 4, 1850, five months before California achieved statehood; the discovery of oil in the 1890s brought rapid growth to the city. The completion of the Los Angeles Aqueduct in 1913, delivering water from Eastern California assured the city's continued rapid growth; the Los Angeles coastal area was settled by the Chumash tribes. A Gabrieleño settlement in the area was called iyáangẚ, meaning "poison oak place". Maritime explorer Juan Rodríguez Cabrillo claimed the area of southern California for the Spanish Empire in 1542 while on an official military exploring expedition moving north along the Pacific coast from earlier colonizing bases of New Spain in Central and South America.
Gaspar de Portolà and Franciscan missionary Juan Crespí, reached the present site of Los Angeles on August 2, 1769. In 1771, Franciscan friar Junípero Serra directed the building of the Mission San Gabriel Arcángel, the first mission in the area. On September 4, 1781, a group of forty-four settlers known as "Los Pobladores" founded the pueblo they called El Pueblo de Nuestra Señora la Reina de los Ángeles,'The Town of Our Lady the Queen of the Angels'; the present-day city has the largest Roman Catholic Archdiocese in the United States. Two-thirds of the Mexican or settlers were mestizo or mulatto, a mixture of African and European ancestry; the settlement remained a small ranch town for decades, but by 1820, the population had increased to about 650 residents. Today, the pueblo is commemorated in the historic district of Los Angeles Pueblo Plaza and Olvera Street, the oldest part of Los Angeles. New Spain achieved its independence from the Spanish Empire in 1821, the pueblo continued as a part of Mexico.
During Mexican rule, Governor Pío Pico made Los Angeles Alta California's regional capital. Mexican rule ended during the Mexican–American War: Americans took control from the Californios after a series of battles, culminating with the signing of the Treaty of Cahuenga on January 13, 1847. Railroads arrived with the completion of the transcontinental Southern Pacific line to Los Angeles in 1876 and the Santa Fe Railroad in 1885. Petroleum was discovered in the city and surrounding area in 1892, by 1923, the discoveries had helped California become the country's largest oil producer, accounting for about one-quarter of the world's petroleum output. By 1900, the population had grown to more than 102,000; the completion of the Los Angeles Aqueduct in 1913, under the supervision of William Mulholland, assured the continued growth of the city. Due to clauses in the city's charter that prevented the City of Los Angeles from selling or providing water from the aqueduct to any area outside its borders, many adjacent city and communities became compelled to annex themselves into Los Angeles.
Los Angeles created the first municipal zoning ordinance in the United States. On September 14, 1908, the Los Angeles City Council promulgated residential and industrial land use zones; the new ordinance established three residential zones of a single type, where industrial uses were
