The World Trade Organization (WTO) is an intergovernmental organization that is concerned with the regulation of international trade between nations. The WTO officially commenced on 1 January 1995 under the Marrakesh Agreement, signed by 124 nations on 15 April 1994, replacing the General Agreement on Tariffs and Trade (GATT), which commenced in 1948. It is the largest international economic organization in the world.

Japanese mythology embraces Shinto and Buddhist traditions as well as agriculturally-based folk religion. The Shinto pantheon comprises innumerable kami (Japanese for "god(s)" or "spirits"). This article will discuss only the typical elements present in Asian mythology, such as cosmogony, important deities, and the best-known Japanese stories. One notable feature of Japanese mythology is its explanation of the origin of the Imperial Family, which has been used historically to assign godhood to the imperial line. The title of the Emperor of Japan, tennō (天皇), means "heavenly sovereign".

Proof theory is a major branch of mathematical logic that represents proofs as formal mathematical objects, facilitating their analysis by mathematical techniques. Proofs are typically presented as inductively-defined data structures such as plain lists, boxed lists, or trees, which are constructed according to the axioms and rules of inference of the logical system. As such, proof theory is syntactic in nature, in contrast to model theory, which is semantic in nature.

Princeton University is a private Ivy League research university in Princeton, New Jersey. Founded in 1746 in Elizabeth as the College of New Jersey, Princeton is the fourth-oldest institution of higher education in the United States and one of the nine colonial colleges chartered before the American Revolution. The institution moved to Newark in 1747, then to the current site nine years later, and renamed itself Princeton University in 1896. Princeton provides undergraduate and graduate instruction in the humanities, social sciences, natural sciences, and engineering. It offers professional degrees through the Woodrow Wilson School of Public and International Affairs, the School of Engineering and Applied Science, the School of Architecture and the Bendheim Center for Finance. The university has ties with the Institute for Advanced Study, Princeton Theological Seminary and the Westminster Choir College of Rider University. Princeton has the largest endowment per student in the United States. From 2001 to 2018, Princeton University was ranked either first or second among national universities by U.S. News & World Report, holding the top spot for 16 of those 18 years. As of October 2018, 65 Nobel laureates, 15 Fields Medalists and 13 Turing Award laureates have been affiliated with Princeton University as alumni, faculty members or researchers. In addition, Princeton has been associated with 21 National Medal of Science winners, 5 Abel Prize winners, 5 National Humanities Medal recipients, 209 Rhodes Scholars, 139 Gates Cambridge Scholars and 126 Marshall Scholars. Two U.S. Presidents, twelve U.S. Supreme Court Justices (three of whom currently serve on the court) and numerous living billionaires and foreign heads of state are all counted among Princeton's alumni body. Princeton has also graduated many prominent members of the U.S. Congress and the U.S. Cabinet, including eight Secretaries of State, three Secretaries of Defense and three of the past five Chairs of the Federal Reserve.

The Iranian or Iranic languages are a branch of the Indo-Iranian languages in the Indo-European language family that are spoken natively by the Iranian peoples. The Iranian languages are grouped in three stages: Old Iranian (until 400 BC), Middle Iranian (400 BC – 900 AD), and New Iranian (since 900 AD). The two directly attested Old Iranian languages are Old Persian (from the Achaemenid Empire) and Old Avestan (the language of the Avesta). Of the Middle Iranian languages, the better understood and recorded ones are Middle Persian (from the Sasanian Empire), Parthian (from the Parthian Empire), and Bactrian (from the Kushan and Hephthalite empires).

Østfold [²œstfɔl] () is a county in southeastern Norway, bordering Akershus and southwestern Sweden (Västra Götaland County and Värmland), while Buskerud and Vestfold are on the other side of Oslofjord. The county's administrative seat is Sarpsborg. Many manufacturing facilities are situated here, such as the world's most advanced biorefinery, Borregaard in Sarpsborg. Fredrikstad has shipyards. There are granite mines in Østfold and stone from these were used by Gustav Vigeland.

Abortion is the ending of pregnancy due to removing an embryo or fetus before it can survive outside the uterus. An abortion that occurs spontaneously is also known as a miscarriage. When deliberate steps are taken to end a pregnancy, it is called an , or less frequently an "induced miscarriage". The word abortion is often used to mean only induced abortions. A similar procedure after the fetus could potentially survive outside the womb is known as a "late termination of pregnancy" or less accurately as a "late term abortion". When allowed by law, abortion in the developed world is . Modern methods use medication or surgery for abortions. The drug mifepristone in combination with prostaglandin appears to be as safe and effective as surgery during the first and second trimester of pregnancy. The most common surgical technique involves dilating the cervix and using a suction device. Birth control, such as the pill or intrauterine devices, can be used immediately following abortion. When performed legally and safely, induced abortions do not increase the risk of long-term mental or physical problems. In contrast, unsafe abortions (those performed by unskilled individuals, with hazardous equipment, or in unsanitary facilities) cause 47,000 deaths and 5 million hospital admissions each year. The World Health Organization recommends safe and legal abortions be available to all women. Around 56 million abortions are performed each year in the world, with about 45% done unsafely. Abortion rates changed little between 2003 and 2008, before which they decreased for at least two decades as access to family planning and birth control increased. As of 2008, 40% of the world's women had access to legal abortions without limits as to reason. Countries that permit abortions have different limits on how late in pregnancy abortion is allowed. Historically, abortions have been attempted using herbal medicines, sharp tools, forceful massage, or through other traditional methods. Abortion laws and cultural or religious views of abortions are different around the world. In some areas abortion is legal only in specific cases such as rape, problems with the fetus, poverty, risk to a woman's health, or incest. There is debate over the moral, ethical, and legal issues of abortion. Those who oppose abortion often argue that an embryo or fetus is a human with a right to life, and so they may compare abortion to murder. Those who favor the legality of abortion often hold that it is part of a woman's right to make decisions about her own body. Others favor legal and accessible abortion as a public health measure.

Professional wrestling (often shortened to pro wrestling or simply wrestling) is a form of performance art and entertainment which combines athletics with theatrical performance. It takes the form of events, held by touring companies, which mimic a title-match combat sport. The unique form of sport portrayed is fundamentally based on classical and "catch" wrestling, with modern additions of striking attacks, strength-based holds and throws and acrobatic maneuvers. Much of these derive from the influence of various international martial arts. An additional aspect of combat with improvised weaponry is sometimes included to varying degrees. The matches have predetermined outcomesto heighten entertainment valueand all combative maneuvers are executed with the full cooperation of those involved and carefully performed in specific manners intended to lessen the chance of actual injury.These facts were once kept highly secret, but are now a widely accepted open secret. By and large, the true nature of the performance is not discussed by the performing company in official media in order to sustain and promote the willing suspension of disbelief for the audience by maintaining an aura of verisimilitude. Fan communications by individual wrestlers and promotions through outside media (i.e. interviews) will often directly acknowledge the dramatic and "fixed" nature of the spectacle.

Francisco Ferrer Guardia (1859–1909) was a radical freethinker, anarchist, and educationist behind a network of secular, private, libertarian schools in and around Barcelona. His execution, following a revolt in Barcelona, propelled Ferrer into martyrdom and grew an international movement of radicals and liberals, who established schools in his model and promoted his schooling approach. Ferrer was raised on a farm near Barcelona, where he developed republican and anti-clerical convictions. As a train conductor, he transmitted messages for the Republican leader , exiled in France. Following a failed Republican uprising in 1885, Ferrer too moved to Paris with his family, where they stayed for 16 years. Ferrer began to explore anarchism and education. At the turn of the century, Ferrer had resolved to open a libertarian school modeled on Paul Robin's Prévost orphanage school. A large inheritance from a Parisian tutee provided the means to do so. Upon returning to Barcelona in 1901, Ferrer founded the Barcelona Modern School, Escuela Moderna, which sought to provide a secular, libertarian curriculum as an alternative to the religious dogma and compulsory lessons common within Spanish schools. Ferrer's pedagogy borrowed from a tradition of 18th century rationalism and 19th century romanticism. He held that children should wield freewheeling liberties at the expense of conformity, regulation, and discipline. His school eschewed punishments, rewards, and exams, and encouraged practical experience over academic study. The school hosted lectures for adults, a school for teacher training, and a radical printing press, which printed textbooks and the school's journal. Around 120 offshoots of the school spread throughout Spain. The rapidity of Ferrer's rise troubled Spanish church and state authorities, who viewed the school as a front for insurrectionary activity. Ferrer was held in association with the 1906 assassination attempt on the Spanish King, which was used as a pretext for closing the school, but was ultimately released without conviction under international pressure a year later. Ferrer traveled Europe as an advocate of the Spanish revolutionary cause, founded a libertarian education advocacy organization, and reopened his press. In mid-1909, Ferrer was arrested and accused of orchestrating a week of insurrection known as Barcelona's Tragic Week. Though Ferrer's involvement was likely not as blameless as intimated by his peers, he did not mastermind the events as charged. The ensuing court case, remembered as a show trial by a kangaroo court, resulted in Ferrer's execution and triggered international outcry, as Ferrer was widely believed to be innocent at the time of his death. He was prominently memorialized in writing, monuments, and demonstrations across three continents. The protest became an movement to propagate his educational ideas, and Modern Schools in his name sprouted across the United States and Europe, reaching into Brazil and Asia.

Gothic architecture is a style that flourished in Europe during the High and Late Middle Ages. It evolved from Romanesque architecture and was succeeded by Renaissance architecture. Originating in 12th-century France, it was widely used, especially for cathedrals and churches, until the 16th century. Its most prominent features included the use of the rib vault and the flying buttress, which allowed the weight of the roof to be counterbalanced by buttresses outside the building, giving greater height and more space for windows. Another important feature was the extensive use of stained glass, and the rose window, to bring light and color to the interior. Another feature was the use of realistic statuary on the exterior, particularly over the portals, to illustrate biblical stories for the largely illiterate parishioners. These technologies had all existed in Romanesque architecture, but they were used in more innovative ways and more extensively in Gothic architecture to make buildings taller, lighter and stronger. The first notable example is generally considered to be the Abbey of Saint-Denis, near Paris, whose choir and facade were reconstructed with Gothic features. The choir was completed in 1144. The style also appeared in some civic architecture in northern Europe, notably in town halls and university buildings. A Gothic revival began in mid-18th-century England, spread through 19th century Europe and continued, largely for ecclesiastical and university structures, into the 20th century.

Nuclear physics is the field of physics that studies atomic nuclei and their constituents and interactions. Other forms of nuclear matter are also studied.Nuclear physics should not be confused with atomic physics, which studies the atom as a whole, including its electrons. Discoveries in nuclear physics have led to applications in many fields. This includes nuclear power, nuclear weapons, nuclear medicine and magnetic resonance imaging, industrial and agricultural isotopes, ion implantation in materials engineering, and radiocarbon dating in geology and archaeology. Such applications are studied in the field of nuclear engineering. Particle physics evolved out of nuclear physics and the two fields are typically taught in close association. Nuclear astrophysics, the application of nuclear physics to astrophysics, is crucial in explaining the inner workings of stars and the origin of the chemical elements.

Folk music includes and the genre that evolved from it during the 20th-century folk revival. Some types of folk music may be called world music. Traditional folk music has been defined in several ways: as music transmitted orally, music with unknown composers, or music performed by custom over a long period of time. It has been contrasted with commercial and classical styles. The term originated in the 19th century, but folk music extends beyond that.

Chess is a two-player strategy board game played on a chessboard, a checkered gameboard with 64 squares arranged in an 8×8 grid. The game is played by millions of people worldwide. Chess is believed to be derived from the Indian game chaturanga some time before the 7th century. Chaturanga is also the likely ancestor of the Eastern strategy games xiangqi, janggi, and shogi. Chess reached Europe by the 9th century, due to the Umayyad conquest of Hispania. The pieces assumed their current powers in Spain in the late 15th century with the introduction of "Mad Queen Chess"; the modern rules were standardized in the 19th century.

Fictional representations of Mars have been popular for over a century. Interest in Mars has been stimulated by the planet's dramatic red color, by early scientific speculations that its surface conditions might be capable of supporting life, and by the possibility that Mars could be colonized by humans in the future. Almost as popular as stories about Mars are stories about Martians engaging in activity (frequently invasions) away from their home planet.

Brazilian literature is the literature written in the Portuguese language by Brazilians or in Brazil, including works written prior to the country's independence in 1822. Throughout its early years, literature from Brazil followed the literary trends of Portugal, whereas gradually shifting to a different and authentic writing style in the course of the 19th and 20th centuries, in the search for truly Brazilian themes and use of the Portuguese language.

Of the Middle Iranian languages, the better understood and recorded ones are Middle Persian (from the Sasanian Empire), Parthian (from the Parthian Empire), and Bactrian (from the Kushan and Hephthalite empires). As of 2008, there were an estimated 150–200 million native speakers of the Iranian languages. Ethnologue estimates that there are 86 Iranian languages, the largest among them being Persian, Pashto, and the Kurdish dialect continuum.

Legal ethics, principles of conduct that members of the legal profession are expected to observe in their practice. They are an outgrowth of the development of the legal profession itself.

The 1936 Soviet Constitution, adopted on 5 December 1936 and also known as the Stalin Constitution, redesigned the government of the Soviet Union. It purported to be highly democratic, with multiple guarantees of rights and democratic procedures. Supporters around the world hailed it as the most democratic constitution imaginable. In practice, it solidified the total control of the Communist Party and its leader Joseph Stalin. Historian J. Arch Getty concludes: Many who lauded Stalin's Soviet Union as the most democratic country on earth lived to regret their words. After all, the Soviet Constitution of 1936 was adopted on the eve of the Great Terror of the late 1930s; the "thoroughly democratic" elections to the first Supreme Soviet permitted only uncontested candidates and took place at the height of the savage violence in 1937. The civil rights, personal freedoms, and democratic forms promised in the Stalin constitution were trampled almost immediately and remained dead letters until long after Stalin's death. Beginning in 1936, 5 December was celebrated as Soviet Constitution day in the Soviet Union until the 1977 Soviet Constitution moved the day to 7 October. Before 1936, there was no Soviet Constitution day. Many countries in the Eastern bloc adopted constitutions that were closely modeled on the Stalin Constitution.

Almost as popular as stories about Mars are stories about Martians engaging in activity (frequently invasions) away from their home planet. In the 20th century, actual spaceflights to the planet Mars, including seminal events such as the first man-made object to impact the surface of Mars in 1971, and then later the first landing of "the first mechanized device to successfully operate on Mars" in 1976 (in the Viking program by the United States), inspired a great deal of interest in Mars-related fiction. Exploration of the planet has continued in the 21st century on to the present day.

Chess is believed to be derived from the Indian game chaturanga some time before the 7th century. Chaturanga is also the likely ancestor of the Eastern strategy games xiangqi, janggi, and shogi. Chess reached Europe by the 9th century, due to the Umayyad conquest of Hispania. The pieces assumed their current powers in Spain in the late 15th century with the introduction of "Mad Queen Chess"; the modern rules were standardized in the 19th century. Play does not involve hidden information. Each player begins with 16 pieces: one king, one queen, two rooks, two knights, two bishops, and eight pawns. Each of the six piece types differently, with the most powerful being the queen and the least powerful the pawn. The objective is to checkmate the opponent's king by placing it under an inescapable threat of capture. To this end, a player's pieces are used to attack and capture the opponent's pieces, while supporting each other. During the game, play typically involves making exchanges of one piece for an opponent's similar piece, but also finding and engineering opportunities to trade advantageously, or to get a better position. In addition to checkmate, a player wins the game if the opponent resigns, or (in a timed game) runs out of time. There are also several ways that a game can end in a draw. The first generally recognized World Chess Champion, Wilhelm Steinitz, claimed his title in 1886. Since 1948, the World Championship has been regulated by the Fédération Internationale des Échecs (FIDE), the game's international governing body. FIDE also awards life-time master titles to skilled players, the highest of which is grandmaster. Many national chess organizations have a title system of their own. FIDE also organizes the Women's World Championship, the World Junior Championship, the World Senior Championship, the Blitz and Rapid World Championships, and the Chess Olympiad, a popular competition among international teams. FIDE is a member of the International Olympic Committee, which can be considered as a recognition of chess as a sport. Several national sporting bodies (for example the Spanish Consejo Superior de Deportes) also recognize chess as a sport. Chess was included in the 2006 and 2010 Asian Games. There is also a Correspondence Chess World Championship and a World Computer Chess Championship. Online chess has opened amateur and professional competition to a wide and varied group of players. Since the second half of the 20th century, computers have been programmed to play chess with increasing success, to the point where the strongest personal computers play at a higher level than the best human players. Since the 1990s, computer analysis has contributed significantly to chess theory, particularly in the endgame. The IBM computer Deep Blue was the first machine to overcome a reigning World Chess Champion in a match when it defeated Garry Kasparov in 1997. The rise of strong chess engines runnable on hand-held devices has led to increasing concerns about cheating during tournaments. There are many variants of chess that utilize different rules, pieces, or boards. One of these, Chess960, incorporates standard rules but employs 960 different possible starting positions, thus negating any advantage in opening preparation. Chess960 has gained widespread popularity as well as some FIDE recognition.

Milton Keynes ( () KEENZ), locally abbreviated to MK, is a large town in Buckinghamshire, England, about 50 miles (80 km) north-west of London. It is the principal settlement of the Borough of Milton Keynes, a unitary authority. At the 2011 Census, its population was 229,000; the Office for National Statistics estimates that it will reach 300,000 by 2025. The River Great Ouse forms its northern boundary; a tributary, the River Ouzel meanders through its linear parks and balancing lakes. Approximately 25% of the urban area is parkland or woodland and includes an SSI. In the 1960s, the UK Government decided that a further generation of new towns in the South East of England was needed to relieve housing congestion in London. The New Town (in planning documents, "New City") of Milton Keynes was to be the biggest yet, with a target population of 250,000, in a "designated area" of about 22,000 acres (9,000 ha). At designation, its area incorporated the existing towns of Bletchley, Wolverton, and Stony Stratford, along with another fifteen villages and farmland in between. These settlements had an extensive historical record since the Norman conquest; detailed archaeological investigations prior to development revealed evidence of human occupation from the neolithic age to modern times, including in particular the Milton Keynes Hoard of Bronze Age gold jewellery. The government established a Development Corporation (MKDC) to design and deliver this New City. The Corporation decided on a softer, more human-scaled landscape than in the earlier new towns but with an emphatically modernist architecture. Recognising how traditional towns and cities had become choked in traffic, they established a 'relaxed' grid of distributor roads about 1 kilometre (0.62 mi) between edges, leaving the spaces between to develop more organically. An extensive network of shared paths for leisure cyclists and pedestrians criss-crosses through and between them. Again rejecting the residential tower blocks that had been so recently fashionable but unloved, they set a height limit of three stories outside the planned centre. Facilities include a 1,400 seat theatre, an art gallery, multiplex cinemas, a 400 seat concert hall, a teaching hospital, a 30,500 seat football stadium and a 65,000 capacity open-air concert venue. There are five railway stations (one inter-city). The Open University is based here and there is a campus of the University of Bedfordshire. Most sports are represented at amateur level; Red Bull Racing (Formula One), MK Dons (association football) and Milton Keynes Lightning (ice hockey) are its professional teams. The Peace Pagoda overlooking Willen Lake was the first such to be built in Europe. Milton Keynes has one of the more successful economies in the UK, ranked highly on a number of criteria. As one of the UK's top five fastest growing centres, it has benefited consistently from above-average economic growth. It has the fifth highest number of business startups per capita (but equally of business failures). It is home to several major national and international companies. However, "despite MK’s record of economic success, poverty remains a growing problem, affecting more and more local families who are not benefiting from the thriving local economy".

Swedish literature refers to literature written in the Swedish language or by writers from Sweden. The first literary text from Sweden is the Rök Runestone, carved during the Viking Age circa 800 AD. With the conversion of the land to Christianity around 1100 AD, Sweden entered the Middle Ages, during which monastic writers preferred to use Latin. Therefore, there are only a few texts in the Old Swedish from that period. Swedish literature only flourished when the Swedish language was standardized in the 16th century, a standardization largely due to the full translation of the Bible into Swedish in 1541. This translation is the so-called Gustav Vasa Bible.

Colombia is a unitary republic made up of thirty-two departments (Spanish: departamentos, sing. departamento) and a Capital District (Distrito Capital). Each department has a Governor (gobernador) and a Department Assembly (Asamblea Departamental), elected by popular vote for a four-year period. The governor cannot be re-elected in consecutive periods. Departments are country subdivisions and are granted a certain degree of autonomy. Departments are formed by a grouping of municipalities (municipios, sing. municipio). Municipal government is headed by mayor (alcalde) and administered by a Municipal Council (concejo municipal), both of which are elected for four-year periods.

Throughout its early years, literature from Brazil followed the literary trends of Portugal, whereas gradually shifting to a different and authentic writing style in the course of the 19th and 20th centuries, in the search for truly Brazilian themes and use of the Portuguese language. Portuguese is a Romance dialect and the sole official language of Brazil. Lyrically, the poet Olavo Bilac, named it " (...) desconhecida e obscura./ Tuba de alto clangor, lira singela,/ Que tens o trom e o silvo da procela,/ E o arrolo da saudade e da ternura! ", which roughly translates as "(...) unknown and obscure,/ Tuba of high blare, delicate lyre,/ That holds the frill and the hiss of the tempest/ And the singing of the saudade and of the tenderness!" Brazil's most significant literary award is the Camões Prize, which it shares with the entire Portuguese sprachraum. As of 2016, Brazil has eleven recipients of the prize. Brazil also holds its own literary academy, the Brazilian Academy of Letters, a non-profit cultural organization pointed in perpetuating the care of the national language and literature. Brazilian literature has been very prolific. Having as birth the letter of Pero Vaz de Caminha, the document that marks the discovery of Brazil, the country's literature has encompassed several significant writers. Major figures include novelists Machado de Assis, Guimarães Rosa, Jorge Amado, Clarice Lispector and Graciliano Ramos; poets such as João Cabral de Melo Neto, Mario de Andrade, Carlos Drummond de Andrade, Vinicius de Moraes, Ferreira Gullar and Manuel Bandeira; dramatists like Nelson Rodrigues and Augusto Boal, and literary critics and theorists as Antonio Candido and Otto Maria Carpeaux, among others.

Devon (), also known as Devonshire, which was formerly its common and official name, is a county of England, reaching from the Bristol Channel in the north to the English Channel in the south. It is part of South West England, bounded by Cornwall to the west, Somerset to the north east, and Dorset to the east. The city of Exeter is the county town. The county includes the districts of East Devon, Mid Devon, North Devon, South Hams, Teignbridge, Torridge, and West Devon. Plymouth and Torbay are each geographically part of Devon, but are administered as unitary authorities. Combined as a ceremonial county, Devon's area is 6,707 km2 (2,590 square miles) and its population is about 1.1 million.

Bahrain ( (); Arabic: البحرين‎ al-Baḥrayn Arabic pronunciation: [aɫ baħrajn] ()), officially the Kingdom of Bahrain (Arabic: مملكة البحرين‎ ), is an island country in the Persian Gulf. The sovereign state comprises a small archipelago centered around Bahrain Island, situated between the Qatar peninsula and the north eastern coast of Saudi Arabia, to which it is connected by the 25-kilometre (16 mi) King Fahd Causeway. Bahrain's population is 1,234,571 (c. 2010), including 666,172 non-nationals. It is 765.3 square kilometres (295.5 sq mi) in size, making it the third-smallest nation in Asia after the Maldives and Singapore.

Andrology (from Ancient Greek: ἀνήρ, anēr, genitive ἀνδρός, andros, "man"; and -λογία, -logia) is the medical specialty that deals with male health, particularly relating to the problems of the male reproductive system and urological problems that are unique to men. It is the counterpart to gynaecology, which deals with medical issues which are specific to female health, especially reproductive and urologic health.

The World Trade Organization (WTO) is an intergovernmental organization that is concerned with the regulation of international trade between nations. The WTO officially commenced on 1 January 1995 under the Marrakesh Agreement, signed by 124 nations on 15 April 1994, replacing the General Agreement on Tariffs and Trade (GATT), which commenced in 1948. It is the largest international economic organization in the world. The WTO deals with regulation of trade in goods, services and intellectual property between participating countries by providing a framework for negotiating trade agreements and a dispute resolution process aimed at enforcing participants' adherence to WTO agreements, which are signed by representatives of member governments and ratified by their parliaments. The WTO prohibits discrimination between trading partners, but provides exceptions for environmental protection, national security, and other important goals. Trade-related disputes are resolved by independent judges at the WTO through a dispute resolution process. The WTO's current Director-General is Roberto Azevêdo, who leads a staff of over 600 people in Geneva, Switzerland. A trade facilitation agreement, part of the Bali Package of decisions, was agreed by all members on 7 December 2013, the first comprehensive agreement in the organization's history. On 23 January 2017, the amendment to the WTO Trade Related Aspects of Intellectual Property Rights (TRIPS) Agreement marks the first time since the organization opened in 1995 that WTO accords have been amended, and this change should secure for developing countries a legal pathway to access affordable remedies under WTO rules. Studies show that the WTO boosted trade, and that barriers to trade would be higher in the absence of the WTO. The WTO has highly influenced the text of trade agreements, as "nearly all recent [preferential trade agreements (PTAs)] reference the WTO explicitly, often dozens of times across multiple chapters... in many of these same PTAs we find that substantial portions of treaty language—sometime the majority of a chapter—is copied verbatim from a WTO agreement."

Proof theory is a major branch of mathematical logic that represents proofs as formal mathematical objects, facilitating their analysis by mathematical techniques. Proofs are typically presented as inductively-defined data structures such as plain lists, boxed lists, or trees, which are constructed according to the axioms and rules of inference of the logical system. As such, proof theory is syntactic in nature, in contrast to model theory, which is semantic in nature. Some of the major areas of proof theory include structural proof theory, ordinal analysis, provability logic, reverse mathematics, proof mining, automated theorem proving, and proof complexity. Much research also focuses on applications in computer science, linguistics, and philosophy.

Mars is the fourth planet from the Sun and the second-smallest planet in the Solar System after Mercury. In English, Mars carries a name of the Roman god of war, and is often referred to as the "Red Planet" because the reddish iron oxide prevalent on its surface gives it a reddish appearance that is distinctive among the astronomical bodies visible to the naked eye. Mars is a terrestrial planet with a thin atmosphere, having surface features reminiscent both of the impact craters of the Moon and the valleys, deserts, and polar ice caps of Earth.

Bahrain ( (); Arabic: البحرين‎ al-Baḥrayn Arabic pronunciation: [aɫ baħrajn] ()), officially the Kingdom of Bahrain (Arabic: مملكة البحرين‎ ), is an island country in the Persian Gulf. The sovereign state comprises a small archipelago centered around Bahrain Island, situated between the Qatar peninsula and the north eastern coast of Saudi Arabia, to which it is connected by the 25-kilometre (16 mi) King Fahd Causeway. Bahrain's population is 1,234,571 (c. 2010), including 666,172 non-nationals. It is 765.3 square kilometres (295.5 sq mi) in size, making it the third-smallest nation in Asia after the Maldives and Singapore. Bahrain is the site of the ancient Dilmun civilisation. It has been famed since antiquity for its pearl fisheries, which were considered the best in the world into the 19th century. Bahrain was one of the earliest areas to convert to Islam, in 628 CE. Following a period of Arab rule, Bahrain was occupied by the Portuguese in 1521, who in turn were expelled in 1602 by Shah Abbas I of the Safavid dynasty under the Persian Empire. In 1783, the Bani Utbah clan captured Bahrain from Nasr Al-Madhkur and it has since been ruled by the Al Khalifa royal family, with Ahmed al Fateh as Bahrain's first hakim. In the late 1800s, following successive treaties with the British, Bahrain became a protectorate of the United Kingdom. In 1971, Bahrain declared independence. Formerly an emirate, the Arab constitutional monarchy of Bahrain was declared a kingdom in 2002. In 2011, the country experienced protests inspired by the regional Arab Spring. Bahrain's ruling al-Khalifa royal family has been accused and criticized for human rights abuses, including imprisonment, torture and execution of dissidents, political opposition figures and its Shia Muslim population. Bahrain had the first post-oil economy in the Persian Gulf. Since the late 20th century, Bahrain has invested in the banking and tourism sectors. Many large financial institutions have a presence in Manama, the country's capital. It has a high Human Development Index and is recognised by the World Bank as a high-income economy. Bahrain is a member of the United Nations, Non-Aligned Movement, Arab League, Organisation of Islamic Cooperation and the Gulf Cooperation Council.

In mathematics, geometric topology is the study of manifolds and maps between them, particularly embeddings of one manifold into another.

Folk music includes and the genre that evolved from it during the 20th-century folk revival. Some types of folk music may be called world music. Traditional folk music has been defined in several ways: as music transmitted orally, music with unknown composers, or music performed by custom over a long period of time. It has been contrasted with commercial and classical styles. The term originated in the 19th century, but folk music extends beyond that. Starting in the mid-20th century, a new form of popular folk music evolved from traditional folk music. This process and period is called the (second) folk revival and reached a zenith in the 1960s. This form of music is sometimes called contemporary folk music or folk revival music to distinguish it from earlier folk forms. Smaller, similar revivals have occurred elsewhere in the world at other times, but the term folk music has typically not been applied to the new music created during those revivals. This type of folk music also includes fusion genres such as folk rock, folk metal, and others. While contemporary folk music is a genre generally distinct from traditional folk music, in U.S. English it shares the same name, and it often shares the same performers and venues as traditional folk music.

Østfold [²œstfɔl] () is a county in southeastern Norway, bordering Akershus and southwestern Sweden (Västra Götaland County and Värmland), while Buskerud and Vestfold are on the other side of Oslofjord. The county's administrative seat is Sarpsborg. Many manufacturing facilities are situated here, such as the world's most advanced biorefinery, Borregaard in Sarpsborg. Fredrikstad has shipyards. There are granite mines in Østfold and stone from these were used by Gustav Vigeland. The county slogan is "The heartland of Scandinavia". The local dialect is characterized by its geographical proximity to Sweden.

Swedish literature refers to literature written in the Swedish language or by writers from Sweden. The first literary text from Sweden is the Rök Runestone, carved during the Viking Age circa 800 AD. With the conversion of the land to Christianity around 1100 AD, Sweden entered the Middle Ages, during which monastic writers preferred to use Latin. Therefore, there are only a few texts in the Old Swedish from that period. Swedish literature only flourished when the Swedish language was standardized in the 16th century, a standardization largely due to the full translation of the Bible into Swedish in 1541. This translation is the so-called Gustav Vasa Bible. With improved education and the freedom brought by secularisation, the 17th century saw several notable authors develop the Swedish language further. Some key figures include Georg Stiernhielm (17th century), who was the first to write classical poetry in Swedish; Johan Henric Kellgren (18th century), the first to write fluent Swedish prose; Carl Michael Bellman (late 18th century), the first writer of burlesque ballads; and August Strindberg (late 19th century), a socio-realistic writer and playwright who won worldwide fame. In Sweden, the period starting in 1880 is known as realism because the writing had a strong focus on social realism. In the 1900s, one of the earliest novelists was Hjalmar Söderberg. The early 20th century continued to produce notable authors, such as Selma Lagerlöf (Nobel laureate 1909) and Pär Lagerkvist (Nobel laureate 1951). A well-known proletarian writer who gained fame after World War I was Vilhelm Moberg; between 1949 and 1959, he wrote the four-book series The Emigrants (Swedish: Utvandrarna), often considered one of the best literary works from Sweden. In the 1960s, Maj Sjöwall and Per Wahlöö collaborated to produce a series of internationally acclaimed detective novels. The most successful writer of detective novels is Henning Mankell, whose works have been translated into 37 languages. In the spy fiction genre, the most successful writer is Jan Guillou. In recent decades, a handful of Swedish writers have established themselves internationally, such as the detective novelist Henning Mankell and thriller writer Stieg Larsson. Also well known outside of Sweden is the children's book writer Astrid Lindgren, author of works such as Pippi Longstocking and Emil of Maple Hills. There is also a strong tradition of Swedish as a literary language in Finland; after the separation in the start of the 19th century, Finland has produced writers such as Johan Ludvig Runeberg, who wrote the Finnish national epic The Tales of Ensign Stål, and Tove Jansson.

Japanese mythology embraces Shinto and Buddhist traditions as well as agriculturally-based folk religion. The Shinto pantheon comprises innumerable kami (Japanese for "god(s)" or "spirits"). This article will discuss only the typical elements present in Asian mythology, such as cosmogony, important deities, and the best-known Japanese stories. Japanese myths, as generally recognized in the mainstream today, are based on the Kojiki, the Nihon Shoki, and some complementary books. The Kojiki, or "Record of Ancient Matters", is the oldest surviving account of Japan's myths, legends and history. The Shintōshū describes the origins of Japanese deities from a Buddhist perspective, while the Hotsuma Tsutae records a substantially different version of the mythology. One notable feature of Japanese mythology is its explanation of the origin of the Imperial Family, which has been used historically to assign godhood to the imperial line. The title of the Emperor of Japan, tennō (天皇), means "heavenly sovereign". Japanese is not transliterated consistently across all sources, see:

The Czech Republic is a unitary parliamentary constitutional republic, in which the President is the head of state and the Prime Minister is the head of government. Executive power is exercised by the Government of the Czech Republic which reports to the lower house of Parliament. The Legislature is bicameral, with the Chamber of Deputies (Poslanecká sněmovna) consisting of 200 members and the Senate (Senát) consisting of 81 members. Both houses together make up the Parliament of the Czech Republic. The political system of the Czech Republic is a multi-party system. Since 1993, the two largest parties were Czech Social Democratic Party (ČSSD) and Civic Democratic Party (ODS). This model changed in early 2014, with the rise of a new political party ANO 2011 which led to weakening of both major parties. The Economist Intelligence Unit has rated the Czech Republic as "flawed democracy" in 2016.

The politics of the Netherlands take place within the framework of a parliamentary representative democracy, a constitutional monarchy and a decentralised unitary state. The Netherlands is described as a consociational state. Dutch politics and governance are characterised by a common striving for broad consensus on important issues, within both of the political community and society as a whole. The Economist Intelligence Unit rated the Netherlands as a "full democracy" in 2016.

Mars is the fourth planet from the Sun and the second-smallest planet in the Solar System after Mercury. In English, Mars carries a name of the Roman god of war, and is often referred to as the "Red Planet" because the reddish iron oxide prevalent on its surface gives it a reddish appearance that is distinctive among the astronomical bodies visible to the naked eye. Mars is a terrestrial planet with a thin atmosphere, having surface features reminiscent both of the impact craters of the Moon and the valleys, deserts, and polar ice caps of Earth. The rotational period and seasonal cycles of Mars are likewise similar to those of Earth, as is the tilt that produces the seasons. Mars is the site of Olympus Mons, the largest volcano and second-highest known mountain in the Solar System, and of Valles Marineris, one of the largest canyons in the Solar System. The smooth Borealis basin in the northern hemisphere covers 40% of the planet and may be a giant impact feature. Mars has two moons, Phobos and Deimos, which are small and irregularly shaped. These may be captured asteroids, similar to 5261 Eureka, a Mars trojan. There are ongoing investigations assessing the past habitability potential of Mars, as well as the possibility of extant life. Future astrobiology missions are planned, including the Mars 2020 and ExoMars rovers. Liquid water cannot exist on the surface of Mars due to low atmospheric pressure, which is less than 1% of the Earth's, except at the lowest elevations for short periods. The two polar ice caps appear to be made largely of water. The volume of water ice in the south polar ice cap, if melted, would be sufficient to cover the entire planetary surface to a depth of 11 meters (36 ft). In November 2016, NASA reported finding a large amount of underground ice in the Utopia Planitia region of Mars. The volume of water detected has been estimated to be equivalent to the volume of water in Lake Superior. Mars can easily be seen from Earth with the naked eye, as can its reddish coloring. Its apparent magnitude reaches −2.94, which is surpassed only by Jupiter, Venus, the Moon, and the Sun. Optical ground-based telescopes are typically limited to resolving features about 300 kilometers (190 mi) across when Earth and Mars are closest because of Earth's atmosphere.

Princeton University is a private Ivy League research university in Princeton, New Jersey. Founded in 1746 in Elizabeth as the College of New Jersey, Princeton is the fourth-oldest institution of higher education in the United States and one of the nine colonial colleges chartered before the American Revolution. The institution moved to Newark in 1747, then to the current site nine years later, and renamed itself Princeton University in 1896.

Francisco Ferrer Guardia (1859–1909) was a radical freethinker, anarchist, and educationist behind a network of secular, private, libertarian schools in and around Barcelona. His execution, following a revolt in Barcelona, propelled Ferrer into martyrdom and grew an international movement of radicals and liberals, who established schools in his model and promoted his schooling approach.

Sexology is the scientific study of human sexuality, including human sexual interests, behaviors, and functions. The term sexology does not generally refer to the non-scientific study of sexuality, such as political science or social criticism. Sexologists apply tools from several academic fields, such as biology, medicine, psychology, epidemiology, sociology, and criminology. Topics of study include sexual development (puberty), sexual orientation, gender identity, sexual relationships, sexual activities, paraphilias, atypical sexual interests. It also includes the study of sexuality across the lifespan, including child sexuality, puberty, adolescent sexuality, and sexuality among the elderly. Sexology also spans sexuality among the mentally and/or physically disabled. The sexological study of sexual dysfunctions and disorders, including erectile dysfunction, anorgasmia, and pedophilia, are also mainstays.

Colombia is a unitary republic made up of thirty-two departments (Spanish: departamentos, sing. departamento) and a Capital District (Distrito Capital). Each department has a Governor (gobernador) and a Department Assembly (Asamblea Departamental), elected by popular vote for a four-year period. The governor cannot be re-elected in consecutive periods. Departments are country subdivisions and are granted a certain degree of autonomy.

Devon (), also known as Devonshire, which was formerly its common and official name, is a county of England, reaching from the Bristol Channel in the north to the English Channel in the south. It is part of South West England, bounded by Cornwall to the west, Somerset to the north east, and Dorset to the east. The city of Exeter is the county town. The county includes the districts of East Devon, Mid Devon, North Devon, South Hams, Teignbridge, Torridge, and West Devon. Plymouth and Torbay are each geographically part of Devon, but are administered as unitary authorities. Combined as a ceremonial county, Devon's area is 6,707 km2 (2,590 square miles) and its population is about 1.1 million. Devon derives its name from Dumnonia. During the British Iron Age, Roman Britain, and the early Middle Ages, this was the homeland of the Dumnonii Brittonic Celts. (The shift from "M" to "V" is a typical Celtic consonant shift.) The Anglo-Saxon settlement of Britain resulted in the partial assimilation of Dumnonia into the Kingdom of Wessex during the eighth and ninth centuries. The western boundary with Cornwall was set at the River Tamar by King Æthelstan in 936. Devon was later constituted as a shire of the Kingdom of England. The north and south coasts of Devon each have both cliffs and sandy shores, and the county's bays contain seaside resorts, fishing towns, and ports. The inland terrain is rural and generally hilly, and has a lower population density than many other parts of England. Dartmoor is the largest open space in southern England, at 954 km2 (368 square miles); its moorland extends across a large expanse of granite bedrock. To the north of Dartmoor are the Culm Measures and Exmoor. In the valleys and lowlands of south and east Devon the soil is more fertile, drained by rivers including the Exe, the Culm, the Teign, the Dart, and the Otter. As well as agriculture, much of the economy of Devon is based on tourism. The comparatively mild climate, coastline and landscape make Devon a destination for recreation and leisure in England, with visitors particularly attracted to the Dartmoor and Exmoor national parks; its coasts, including the resort towns along the south coast known collectively as the English Riviera; the Jurassic Coast, and North Devon's UNESCO Biosphere Reserve; and the countryside including the Cornwall and West Devon Mining Landscape.
