Mange is a parasitic disease caused by mites which live in or under the skin and affect all kinds of animals and man, causing scabby eczema and depilation. Emaciation may occur in chronic cases and under cold conditions or with poor nutrition; heavily infested cattle may die from psoroptic mange. Sarcoptic mange may cause mastitis in milking cows.
Mange is a world-wide problem, and there are three kinds of mange mites: psoroptic, chorioptic and sarcoptic which attack a variety of animals. Cattle are also affected by demodectic mange mites. Within these groupings there are many different species. Transmission is generally from one animal to another and for this reason among domestic animals there is a far higher incidence during the winter when they are confined in close quarters. The mites eggs may remain on barn walls, fence posts, cattle trucks or any other equipment which comes into contact with diseased animals and they may be transmitted in this way.
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.
