Hot weather violence Aberrant behaviour under extreme weather conditions
The link between aggression and hot weather is long-noted but it is still not proven why heat has this effect and how great the problem is. July and August in the USA are on average both the hottest months and the most criminally violent. Explanations range from increased irritability with summer heat to the combination of increased drinking, people gathering outdoors in public places and spending more time with families. Some research suggests regional differences: in Dallas, US, where high temperatures are the norm in summer, behavioural changes were most marked during a combination of heat and extreme weather conditions such as storminess. It is argued that such conditions make people uncomfortable and disrupt them psychologically.
The Encyclopedia of World Problems and Human Potential is a collaboration between UIA and Mankind 2000, started in 1972. It is the result of an ambitious effort to collect and present information on the problems with which humanity is confronted, as well as the challenges such problems pose to concept formation, values and development strategies. Problems included are those identified in international periodicals but especially in the documents of some 60,000 international non-profit organizations, profiled in the Yearbook of International Organizations.
The Encyclopedia includes problems which such groups choose to perceive and act upon, whether or not their existence is denied by others claiming greater expertise. Indeed such claims and counter-claims figure in many of the problem descriptions in order to reflect the often paralyzing dynamics of international debate. In the light of the interdependence demonstrated among world problems in every sector, emphasis is placed on the need for approaches which are sufficiently complex to encompass the factions, conflicts and rival worldviews that undermine collective initiative towards a promising future.
Non-profit, apolitical, independent, and non-governmental in nature, the UIA has been a pioneer in the research, monitoring and provision of information on international organizations, international associations and their global challenges since 1907.
