Caste System (caste + system)
Selected AbstractsPersecution of Indian ChristiansDIALOG, Issue 2 2002Monica Melanchthon Christians are one among many minority religious groups in India that face "persecution.""Persecution" here relates to the unjust treatment of lower classes in the Hindu caste system; it is not only Christians that are persecuted, but all those who fall in the lower castes. Part of the animosity towards Christians, then, is due to the fact that many Christian schools have been built to educate the masses thereby upsetting the existing caste system; furthermore, Christianity preaches a classless gospel. Persecution of Christians in India takes place under the guise that Christian Missionaries are covertly trying to convert Hindu,Indian society to the western cult of individualism. Government propaganda, laws, and programs designed to thwart Christian efforts, feed off of this mentality. Unfortunately, there are certain Christian groups that feed off of the misery of people in an unjust caste,system, offering salvation through conversion. These groups do not help matters at all; in fact, they add fuel to the fire. [source] New role for majors in Atta leafcutter antsECOLOGICAL ENTOMOLOGY, Issue 5 2007SOPHIE E. F. EVISON Abstract 1.,Atta (Hymenoptera: Formicidae) leafcutter ants display the most polymorphic worker caste system in ants, with different sizes specialising in different tasks. The largest workers (majors) have large, powerful mandibles and are mainly associated with colony defence. 2.,Majors were observed cutting fallen fruit and this phenomenon was investigated in the field by placing mango fruit near natural Atta laevigata and Atta sexdens colonies in São Paulo State, Brazil. 3.,Ants cutting the fruit were significantly heavier (mean = 49.1 mg, SD = 11.1 mg, n= 90) than the ants carrying the fruit back to the nest (mean = 20.9 mg, SD = 9.2 mg, n= 90). 4.,Fruit pieces cut by majors were small (mean = 15.9 mg), approximately half the weight of leaf pieces (mean = 28.5 mg) cut and carried by media foragers. It is hypothesised that it is more difficult to cut large pieces from three-dimensional objects, like fruit, compared to two-dimensional objects, like leaves, and that majors, with their longer mandibles, can cut fruit into larger pieces than medias. 5.,The study shows both a new role for Atta majors in foraging and a new example of task partitioning in the organisation of foraging. [source] Caste fate conflict in swarm-founding social Hymenoptera: an inclusive fitness analysisJOURNAL OF EVOLUTIONARY BIOLOGY, Issue 4 2003T. Wenseleers Abstract A caste system in which females develop into morphologically distinct queens or workers has evolved independently in ants, wasps and bees. Although such reproductive division of labour may benefit the colony it is also a source of conflict because individual immature females can benefit from developing into a queen in order to gain greater direct reproduction. Here we present a formal inclusive fitness analysis of caste fate conflict appropriate for swarm-founding social Hymenoptera. Three major conclusions are reached: (1) when caste is self-determined, many females should selfishly choose to become queens and the resulting depletion of the workforce can substantially reduce colony productivity; (2) greater relatedness among colony members reduces this excess queen production; (3) if workers can prevent excess queen production at low cost by controlled feeding, a transition to nutritional caste determination should occur. These predictions generalize results derived earlier using an allele-frequency model [Behav. Ecol. Sociobiol. (2001) 50: 467] and are supported by observed levels of queen production in various taxa, especially stingless bees, where caste can be either individually or nutritionally controlled. [source] West Turns East at the End of HistoryNEW PERSPECTIVES QUARTERLY, Issue 4 2009Octavio Paz Awarded the Nobel Prize for Literature in 1990, Octavio Paz was Latin America's great poet, essayist and critic whose most enduring work was The Labyrinth of Solitude. We would often meet in the late afternoon over scotch on ice at his apartment on Reforma in Mexico City, the warm afternoon rain pounding against the windows of his book-lined study, gazing out toward the Angel of Independence column in the center of that daunting megalopolis. Over the years, we collaborated on several issues of Vuelta, a small but influential journal like NPQ. Paz believed that "the most important things can be said at the margins beyond the entertainment and commercial imperatives of the mass media." Though petty literary politics sometimes intruded, Paz was a truly magnanimous soul whose entire life was an exploration. Everything interested him, from Surrealism to the Indian caste system (he was the Mexican ambassador to India before resigning in 1968 to protest the student massacre at Tlatelolco). He liked to quote Baudelaire, saying that poets were universal translators because they translate the language of the universe,stars, water, trees,into the language of man. Paz died in 1998. We held this conversation in 1992. It also appeared in Vuelta as "La Transformacion del Tiempo: El Encuentro de Oriente y Occidente." [source] The Political Impact of Labor Migration in BahrainCITY & SOCIETY, Issue 1 2008LAURENCE LOUËR Abstract This paper shows that, in Bahrain, the main political consequence of migration has been the deepening of state/society conflict. While having old historical roots, this conflict has been fostered in the recent period by the collapse of the "caste system" that, since the 1970s, used to regulate the relations between foreigners and nationals in the labor market by preventing the two groups from being in competition for jobs. I conclude that in order to evaluate the possible political impact of migration in the Gulf States, one has to look first at the structure of the relation between the national population and the migrants, rather than focus on the number of foreigners. [source] Alternative strategies by thermophilic ants to cope with extreme heat: individual versus colony level traitsOIKOS, Issue 1 2000Xim Cerdá Cataglyphis is a fairly homogeneous ant genus which is widespread over the arid regions of the Old World. All Cataglyphis species are thermal specialists which are adapted to extreme environments where they forage at nearly lethal temperatures. This study focusses on two Cataglyphis species which differ considerably in their physical caste systems. These species have developed two alternative mechanisms facing extreme heat. In C. velox, foraging at high surface temperatures is clearly dependent on size: large C. velox workers forage at midday and are able to withstand higher temperatures than small workers. On the other hand, C. rosenhaueri has not developed great physical specialization, but the workers of this species have achieved physiological (such as low cuticular transpiration and metabolic rate), and behavioural adaptations (such as raising their abdomen to protect the vital organs contained in it from high temperatures) to tolerate thermal stress. The result is that small C. rosenhaueri workers may withstand extreme heat conditions in a similar way to large C. velox workers, and much better than small C. velox workers. The different mechanisms used by these two species to withstand extreme heat could reflect fundamental patterns of independent evolution. In some situations, selection may act to promote a relatively narrow size range of adult workers, all of them able to withstand thermal extremes, while in others it may act by producing different worker sizes with different tolerance to environmental conditions.
