paragraph_text: The principal Treaties that form the European Union began with common rules for coal and steel, and then atomic energy, but more complete and formal institutions were established through the Treaty of Rome 1957 and the Maastricht Treaty 1992 (now: TFEU). Minor amendments were made during the 1960s and 1970s. Major amending treaties were signed to complete the development of a single, internal market in the Single European Act 1986, to further the development of a more social Europe in the Treaty of Amsterdam 1997, and to make minor amendments to the relative power of member states in the EU institutions in the Treaty of Nice 2001 and the Treaty of Lisbon 2007. Since its establishment, more member states have joined through a series of accession treaties, from the UK, Ireland, Denmark and Norway in 1972 (though Norway did not end up joining), Greece in 1979, Spain and Portugal 1985, Austria, Finland, Norway and Sweden in 1994 (though again Norway failed to join, because of lack of support in the referendum), the Czech Republic, Cyprus, Estonia, Hungary, Latvia, Lithuania, Malta, Poland, Slovakia and Slovenia in 2004, Romania and Bulgaria in 2007 and Croatia in 2013. Greenland signed a Treaty in 1985 giving it a special status.

paragraph_text: Switzerland voted against membership in the European Economic Area in a referendum in December 1992 and has since maintained and developed its relationships with the European Union (EU) and European countries through bilateral agreements. In March 2001, the Swiss people refused in a popular vote to start accession negotiations with the EU. In recent years, the Swiss have brought their economic practices largely into conformity with those of the EU in many ways, in an effort to enhance their international competitiveness. The economy grew at 3% in 2010, 1.9% in 2011, and 1% in 2012. Full EU membership is a long-term objective of some in the Swiss government, but there is considerable popular sentiment against this supported by the conservative SVP party. The western French-speaking areas and the urban regions of the rest of the country tend to be more pro-EU, however with far from any significant share of the population.

paragraph_text: Henri Guisan (; 21 October 1874 – 7 April 1960) was a Swiss army officer who held the office of the General of the Swiss Armed Forces during the Second World War. He was the fourth and the most recent man to be appointed to the rarely used Swiss rank of General, and was possibly Switzerland's most famous soldier. He is best remembered for effectively mobilizing the Swiss Armed Forces and Swiss people in order to prepare resistance against a possible invasion by Nazi Germany in 1940. Guisan was voted the fourth-greatest Swiss figure of all time in 2010.

paragraph_text: Although conformity pressures generally increase as the size of the majority increases, a meta - analysis suggests that conformity pressures in Asch's experiment peak once the majority reaches about four or five in number. Moreover, a study suggests that the effects of group size depend on the type of social influence operating. This means that in situations where the group is clearly wrong, conformity will be motivated by normative influence; the participants will conform in order to be accepted by the group. A participant may not feel much pressure to conform when the first person gives an incorrect response. However, conformity pressure will increase as each additional group member also gives the same incorrect response.

paragraph_text: In 1986, Portugal joined the European Economic Community (EEC) that later became the European Union (EU). In the following years Portugal's economy progressed considerably as a result of EEC/EU structural and cohesion funds and Portuguese companies' easier access to foreign markets.

paragraph_text: There have been two major trends in the changing status of pet dogs. The first has been the 'commodification' of the dog, shaping it to conform to human expectations of personality and behaviour. The second has been the broadening of the concept of the family and the home to include dogs-as-dogs within everyday routines and practices.

paragraph_text: During World War II, when Denmark was occupied by Nazi Germany, the United States briefly controlled Greenland for battlefields and protection. In 1946, the United States offered to buy Greenland from Denmark for $100 million ($1.2 billion today) but Denmark refused to sell it. Several politicians and others have in recent years argued that Greenland could hypothetically be in a better financial situation as a part of the United States; for instance mentioned by professor Gudmundur Alfredsson at University of Akureyri in 2014. One of the actual reasons behind US interest in Greenland could be the vast natural resources of the island. According to Wikileaks, the U.S. appears to be highly interested in investing in the resource base of the island and in tapping the vast expected hydrocarbons off the Greenlandic coast.

paragraph_text: The economy of Malmö was traditionally based on shipbuilding (Kockums) and construction related industries, such as concrete factories. The region's leading university, along with its associated hi-tech and pharmaceutical industries, is located in Lund about 16 kilometres (10 miles) to the north-east. As a result, Malmö had a troubled economic situation following the mid-1970s. Between 1990–1995, 27,000 jobs were lost, and the budget deficit was more than one billion Swedish krona (SEK). In 1995, Malmö had Sweden's highest unemployment rate.However, during the last two decades there has been a revival. One contributing factor has been the economic integration with Denmark brought about by the Øresund Bridge, which opened in July 2000. Also the university founded in 1998 and the effects of integration into the European Union have contributed. In 2017 the unemployment rate is still high but Malmö has the last 20 years had one of the strongest employment growth rates in Sweden. But a lot of those jobs are taken by workers outside of the side in the neighboring municipalities.As of 2016, the largest companies were:

paragraph_text: Switzerland joined the Council of Europe in 1963. In 1979 areas from the canton of Bern attained independence from the Bernese, forming the new canton of Jura. On 18 April 1999 the Swiss population and the cantons voted in favour of a completely revised federal constitution.In 2002 Switzerland became a full member of the United Nations, leaving the Vatican City as the last widely recognised state without full UN membership. Switzerland is a founding member of the EFTA, but is not a member of the European Economic Area. An application for membership in the European Union was sent in May 1992, but not advanced since the EEA was rejected in December 1992 when Switzerland was the only country to launch a referendum on the EEA. There have since been several referendums on the EU issue; due to opposition from the citizens, the membership application has been withdrawn. Nonetheless, Swiss law is gradually being adjusted to conform with that of the EU, and the government has signed a number of bilateral agreements with the European Union. Switzerland, together with Liechtenstein, has been completely surrounded by the EU since Austria's entry in 1995. On 5 June 2005, Swiss voters agreed by a 55% majority to join the Schengen treaty, a result that was regarded by EU commentators as a sign of support by Switzerland, a country that is traditionally perceived as independent and reluctant to enter supranational bodies.

paragraph_text: Early inhabitants of the Virgin Islands included the Ciboney, Arawaks, and Island Caribs. The first documented Europeans to visit the islands arrived with Christopher Columbus. The islands were occupied by several nations over the next century, including England, the Dutch Republic, France, and Denmark. In 1733, the Danish West India Company purchased Saint Croix from the French and brought together Saint Thomas, Saint Croix, and Saint John as the Danish West Indies. Danish trading posts were set up on the islands, trading in sugar, slaves and other goods. Sugar cane cultivation was a major economic activity for many years, with slaves used as one of the labor sources. However, following increasing humanitarian awareness, laws against slavery and a slave rebellion in 1848, the governor Peter von Scholten officially freed the last slaves the same year. The islands were purchased from the Danish by the United States in 1917 under the Treaty of the Danish West Indies.

paragraph_text: The Canadian Ballet Festival was an annual event staged in Canada from 1948 to 1954 that brought together various Canadian dance companies to generate public interest in classical dance. Prior to the festivals, it was difficult for professional Canadian dancers to earn a living by practicing their art in their own country. When the festivals ended in 1954 after six years, Canadian dancers were able to find paid work in Canadian television practicing their art.
