Mexico City
Mexico City, or the City of Mexico, is the capital of Mexico and the most populous city in North America. Mexico City is one of the most important financial centres in the Americas, it is located in the Valley of Mexico, a large valley in the high plateaus in the center of Mexico, at an altitude of 2,240 meters. The city has 16 boroughs; the 2009 population for the city proper was 8.84 million people, with a land area of 1,485 square kilometers. According to the most recent definition agreed upon by the federal and state governments, the population of Greater Mexico City is 21.3 million, which makes it the largest metropolitan area of the Western Hemisphere, the eleventh-largest agglomeration, the largest Spanish-speaking city in the world. Greater Mexico City has a GDP of $411 billion in 2011, making Greater Mexico City one of the most productive urban areas in the world; the city was responsible for generating 15.8% of Mexico's GDP, the metropolitan area accounted for about 22% of total national GDP.
If it were an independent country, in 2013, Mexico City would be the fifth-largest economy in Latin America, five times as large as Costa Rica and about the same size as Peru. Mexico’s capital is both the oldest capital city in the Americas and one of two founded by Native Americans, the other being Quito, Ecuador; the city was built on an island of Lake Texcoco by the Aztecs in 1325 as Tenochtitlan, completely destroyed in the 1521 siege of Tenochtitlan and subsequently redesigned and rebuilt in accordance with the Spanish urban standards. In 1524, the municipality of Mexico City was established, known as México Tenochtitlán, as of 1585, it was known as Ciudad de México. Mexico City was the political and financial center of a major part of the Spanish colonial empire. After independence from Spain was achieved, the federal district was created in 1824. After years of demanding greater political autonomy, residents were given the right to elect both a Head of Government and the representatives of the unicameral Legislative Assembly by election in 1997.
Since, the left-wing Party of the Democratic Revolution has controlled both of them. The city has several progressive policies, such as abortion on request, a limited form of euthanasia, no-fault divorce, same-sex marriage. On January 29, 2016, it ceased to be the Federal District, is now known as Ciudad de México, with a greater degree of autonomy. A clause in the Constitution of Mexico, prevents it from becoming a state, as it is the seat of power in the country, unless the capital of the country were relocated elsewhere; the city of Mexico-Tenochtitlan was founded by the Mexica people in 1325. The old Mexica city, now referred to as Tenochtitlan was built on an island in the center of the inland lake system of the Valley of Mexico, which it shared with a smaller city-state called Tlatelolco. According to legend, the Mexicas' principal god, indicated the site where they were to build their home by presenting a golden eagle perched on a prickly pear devouring a rattlesnake. Between 1325 and 1521, Tenochtitlan grew in size and strength dominating the other city-states around Lake Texcoco and in the Valley of Mexico.
When the Spaniards arrived, the Aztec Empire had reached much of Mesoamerica, touching both the Gulf of Mexico and the Pacific Ocean. After landing in Veracruz, Spanish explorer Hernán Cortés advanced upon Tenochtitlan with the aid of many of the other native peoples, arriving there on November 8, 1519. Cortés and his men marched along the causeway leading into the city from Iztapalapa, the city's ruler, Moctezuma II, greeted the Spaniards. Cortés put Moctezuma under house arrest. Tensions increased until, on the night of June 30, 1520 – during a struggle known as "La Noche Triste" – the Aztecs rose up against the Spanish intrusion and managed to capture or drive out the Europeans and their Tlaxcalan allies. Cortés regrouped at Tlaxcala; the Aztecs thought the Spaniards were permanently gone, they elected a new king, Cuitláhuac, but he soon died. Cortés began a siege of Tenochtitlan in May 1521. For three months, the city suffered from the lack of food and water as well as the spread of smallpox brought by the Europeans.
Cortés and his allies landed their forces in the south of the island and fought their way through the city. Cuauhtémoc surrendered in August 1521; the Spaniards razed Tenochtitlan during the final siege of the conquest. Cortés first settled in Coyoacán, but decided to rebuild the Aztec site to erase all traces of the old order, he did not establish a territory under his own personal rule, but remained loyal to the Spanish crown. The first Spanish viceroy arrived in Mexico City fourteen years later. By that time, the city had again become a city-state, having power that extended far beyond its borders. Although the Spanish preserved Tenochtitlan's basic layout, they built Catholic churches over the old Aztec temples and claimed the imperial palaces for themselves. Tenochtitlan was renamed "Mexico"; the city had been the capital of the Aztec empire and in the colonial era, Mexico City became the capital of New Spain. The viceroy of Mexico or vice-king lived in the viceregal palace on Zócalo; the Mexico City Metropolitan Cathedral, the seat of the Archbishopric of New Spain, was const
Heydar Aliyev
Heydar Alirza oglu Aliyev was an Azerbaijani politician who served as the third President of Azerbaijan from October 1993 to October 2003. As national president he held constitutional powers, but his influence on Azerbaijani politics had begun years earlier; as a young man he had joined the Azerbaijan SSR People's Commissariat for State Security and rose to the rank of Major-General. The regime established by Heydar Aliyev in Azerbaijan has been described as dictatorial or authoritarian and repressive. Political commentators highlight that Aliyev ran a heavy-handed police state, that he rigged elections and muzzled the media whereas others emphasize that his balanced policy brought stability to Azerbaijan. Aliyev was born in Nakhchivan City. After graduating from Nakhchivan Pedagogical School, from 1939 to 1941 Aliyev attended the Azerbaijan Industrial Institute, where he studied architecture. In 1949 and 1950, he studied at the USSR MGB Officer Corps Qualifications-Raising School. Aliyev's official biography stated that he studied at Baku State University, graduating with a degree in history in 1957.
According to American journalist Pete Earley, Aliyev first attended the Ministry of State Security Academy in Leningrad, graduating in 1944. He attended senior staff professional development courses at the Dzerzhinsky Higher School of the KGB in Moscow in 1966. In 1948, he married Zarifa Aliyeva. On 12 October 1955, their daughter Sevil was born. On 24 December 1961, their son Ilham was born. Zarifa Aliyeva died of cancer in 1985. Heydar Aliyev served at the Archive Department of the People's Commissariat of Internal Affairs of the Nakhchivan Autonomous Soviet Socialist Republic from 1941 to 1944, before his appointment to the head of General Department of the Council of People's Commissars of the Nakhchivan ASSR. H. Aliyev joined the Azerbaijan SSR People's Commissariat for State Security in 1944, he proceeded to became the department head of State Security Committee of Azerbaijan SSR in 1950, after he graduated from Senior Staff Training School of the USSR State Security Committee. In 1954, as part of a government reform, NKGB became known as Committee for State Security, or the KGB.
Aliyev rose through the KGB ranks, becoming a deputy chairman of the Azerbaijani KGB in 1964, its chairman in 1967, reaching the rank of major general. Aliyev was elected First Secretary of the Central Committee of the Azerbaijan Communist Party at its Plenary Session held on 12 July 1969, amidst a Soviet anti-corruption campaign. Aliyev made some progress in the fight against corruption: a number of people were sentenced to prison terms. In the early 1980s, Aliyev barred the offspring of certain legal personnel from attending the Republic's law school, in a purported effort to curb a self-perpetuating elite based on corruption. In 1977, he visited Iran: Kerbala once. During the period of his leadership of Soviet Azerbaijan, Aliyev's efforts led to increased economic and cultural growth rates in Azerbaijan SSR. Aliyev became the most successful republican leader, raising the profile of the underprivileged republic and promoting Azerbaijanis to senior posts. On 22 November 1982, Yuri Andropov promoted Aliyev from candidate to full member of Soviet Politburo and appointed him to the post of First Deputy Chairman of the Council of Ministers of the USSR, responsible for transportation and social services.
Aliyev thus attained the highest position reached by an Azerbaijani in the Soviet Union. Aliyev was forced to resign from this position in 1987 amidst allegations of corruption made against him by Mikhail Gorbachev. Despite that, CIA report states that, Heydar Aliyev became First Deputy Chairman of USSR Council of Ministers and a full Politburo Member who publicly pledged to fight against corruption, free key state personnel and the economy of the Soviet Union from bribery, it is noted in the report that his colleagues understood his intention to deal harshly with corruption was serious and his commitment to the anti-corruption became his trademark within the Soviet Union. As head of the KGB's branch in Azerbaijan, Aliyev ran an anti-corruption campaign. Following the campaign, he became the undisputed leader of Azerbaijan. Aliyev became a candidate member of the Soviet Politburo in 1976, he ran this position until December 1982, when Yuri Andropov promoted him to the office of First Deputy Chairman of the Council of Ministers.
Heydar Aliyev served at the USSR Council of Ministers as the first deputy chairman in 1974-1979. His star waned following his appointment in 1985 under Mikhail Gorbachev, his political views became something of a liability to him in the era of perestroika, but he still exerted tremendous power in Azerbaijan. After his forced retirement in 1987, Aliyev remained in Moscow until 1990, he suffered a heart attack during this time. Aliyev appeared in the Permanent Mission of Azerbaijan SSR in Moscow, demanded that the organizers and executors of the crime committed against the people of Azerbaijan be punished for a military action which resulted in violent Black January events amidst the brewing Nagorno-Karabakh War. After this public appearance in Moscow, Aliyev resigned his membership in the Communist Party of the Soviet Union and left Moscow for his native Nakhchivan. Here, Aliyev reinvented himself as a moderate nationalist and was subsequently elected deputy to the Supreme Soviet of Azerbai
International Standard Serial Number
An International Standard Serial Number is an eight-digit serial number used to uniquely identify a serial publication, such as a magazine. The ISSN is helpful in distinguishing between serials with the same title. ISSN are used in ordering, interlibrary loans, other practices in connection with serial literature; the ISSN system was first drafted as an International Organization for Standardization international standard in 1971 and published as ISO 3297 in 1975. ISO subcommittee TC 46/SC 9 is responsible for maintaining the standard; when a serial with the same content is published in more than one media type, a different ISSN is assigned to each media type. For example, many serials are published both in electronic media; the ISSN system refers to these types as electronic ISSN, respectively. Conversely, as defined in ISO 3297:2007, every serial in the ISSN system is assigned a linking ISSN the same as the ISSN assigned to the serial in its first published medium, which links together all ISSNs assigned to the serial in every medium.
The format of the ISSN is an eight digit code, divided by a hyphen into two four-digit numbers. As an integer number, it can be represented by the first seven digits; the last code digit, which may be 0-9 or an X, is a check digit. Formally, the general form of the ISSN code can be expressed as follows: NNNN-NNNC where N is in the set, a digit character, C is in; the ISSN of the journal Hearing Research, for example, is 0378-5955, where the final 5 is the check digit, C=5. To calculate the check digit, the following algorithm may be used: Calculate the sum of the first seven digits of the ISSN multiplied by its position in the number, counting from the right—that is, 8, 7, 6, 5, 4, 3, 2, respectively: 0 ⋅ 8 + 3 ⋅ 7 + 7 ⋅ 6 + 8 ⋅ 5 + 5 ⋅ 4 + 9 ⋅ 3 + 5 ⋅ 2 = 0 + 21 + 42 + 40 + 20 + 27 + 10 = 160 The modulus 11 of this sum is calculated. For calculations, an upper case X in the check digit position indicates a check digit of 10. To confirm the check digit, calculate the sum of all eight digits of the ISSN multiplied by its position in the number, counting from the right.
The modulus 11 of the sum must be 0. There is an online ISSN checker. ISSN codes are assigned by a network of ISSN National Centres located at national libraries and coordinated by the ISSN International Centre based in Paris; the International Centre is an intergovernmental organization created in 1974 through an agreement between UNESCO and the French government. The International Centre maintains a database of all ISSNs assigned worldwide, the ISDS Register otherwise known as the ISSN Register. At the end of 2016, the ISSN Register contained records for 1,943,572 items. ISSN and ISBN codes are similar in concept. An ISBN might be assigned for particular issues of a serial, in addition to the ISSN code for the serial as a whole. An ISSN, unlike the ISBN code, is an anonymous identifier associated with a serial title, containing no information as to the publisher or its location. For this reason a new ISSN is assigned to a serial each time it undergoes a major title change. Since the ISSN applies to an entire serial a new identifier, the Serial Item and Contribution Identifier, was built on top of it to allow references to specific volumes, articles, or other identifiable components.
Separate ISSNs are needed for serials in different media. Thus, the print and electronic media versions of a serial need separate ISSNs. A CD-ROM version and a web version of a serial require different ISSNs since two different media are involved. However, the same ISSN can be used for different file formats of the same online serial; this "media-oriented identification" of serials made sense in the 1970s. In the 1990s and onward, with personal computers, better screens, the Web, it makes sense to consider only content, independent of media; this "content-oriented identification" of serials was a repressed demand during a decade, but no ISSN update or initiative occurred. A natural extension for ISSN, the unique-identification of the articles in the serials, was the main demand application. An alternative serials' contents model arrived with the indecs Content Model and its application, the digital object identifier, as ISSN-independent initiative, consolidated in the 2000s. Only in 2007, ISSN-L was defined in the
