The terms "assault and battery" are often used together, although traditionally they represent different and distinct crimes. Battery is the unlawful application of force to the person of another. Criminal assault may be either an attempt to commit battery or intentionally placing another under fear of battery. Simple assault is considered a misdemeanour, but aggravated assault (with intent to kill, rob, rape), possibly with a deadly weapon, may be considered a felony. Weapons may include firearms, corrosive materials, poisons, and cutting, piercing or strangulation instruments, and body parts, such as teeth. Pushing someone from a high place is also an assault.
Neglecting national variations in the basis of statistical estimates, figures from Interpol indicate that in 1990 there were approximately 1,815,000 cases of serious assault reported from 91 countries worldwide, namely 60.0 per 100,000 population; some 1,614,000 (namely 64%) were claimed to have been resolved.
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.
