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 referenda on the EU issue; due to a mixed reaction from the population the membership application has been frozen. 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.
In what year did Switzerland become a full member of the United Nations?

While successful predation results in a gain of energy, hunting invariably involves energetic costs as well. When hunger is not an issue, in general most predators will not seek to attack prey since the costs outweigh the benefits. For instance, a large predatory fish like a shark that is well fed in an aquarium will typically ignore the smaller fish swimming around it (while the prey fish take advantage of the fact that the apex predator is apparently uninterested). Surplus killing represents a deviation from this type of behaviour. The treatment of consumption in terms of cost-benefit analysis is known as optimal foraging theory, and has been quite successful in the study of animal behavior. In general, costs and benefits are considered in energy gain per unit time, though other factors are also important, such as essential nutrients that have no caloric value but are necessary for survival and health.
In optimal foraging theory, how are costs and benefits measured?
energy gain per unit time

Prince Louis intended to land in the south of England in May 1216, and John assembled a naval force to intercept him. Unfortunately for John, his fleet was dispersed by bad storms and Louis landed unopposed in Kent. John hesitated and decided not to attack Louis immediately, either due to the risks of open battle or over concerns about the loyalty of his own men. Louis and the rebel barons advanced west and John retreated, spending the summer reorganising his defences across the rest of the kingdom. John saw several of his military household desert to the rebels, including his half-brother, William Longespee. By the end of the summer the rebels had regained the south-east of England and parts of the north.
