The perception of preschool social dominance

Children's and teachers' perception of social dominance was examined using a behavioral criterion for determining accuracy of verbal judgments. Video records of agonistic interactions were obtained during approximately 60 hours of free-play at two preschool centers. Analyses of social conflict episodes ending in submission revealed linear dominance structures for both groups. Dominance perception was assessed in two ways. Both teachers and children were asked to rank-order a subgroup of children according to dominance. They were also asked to select the more dominant children in a number of predetermined pairs. Results indicated that teachers could accurately judge dyadic dominance relations, and that accuracy among children varied as a function of their status within the group hierarchy. Findings have implications for social dominance assessment methodology, and for the issue of consensual versus ecological validity in developmental studies of social perception.     

Evolution of Destructive Aggression

Aggression is defined as a mechanism of spacing by means of force or displays. It has evolved independently in different animal groups. The mechanisms underlying it are therefore not homologous throughout the animal kingdom. The phenomenon of aggression is so widespread, however, that strong selection pressures must be responsible for its development along analogous lines. Its most obvious functions are in competition for mates, natural resources, and territories, and in the preservation of group identity in many gregarious species. Aggression is often ritualized so that no damage is done to conspecifics. This ritualization may appear as modification of fighting into a tournament, or as the development of submissive postures which block further aggression in the opponent shortly after the onset of a potentially damaging fight. Animal aggression is preprogrammed by phylogenetic adaptation in well-defined ways, but can be modified by experience. The inborn programs involve motor patterns, innate releasing mechanisms, releasers, motivating mechanisms, and learning dispositions specific for the species. Aggression on this biological level can be observed in humans as intragroup aggression. Certain motor patterns and signals which lead to the release of aggression are universal. Some can even be found in deaf- and blind-born people, proving their innateness. A number of patterns of aggression in man are highly ritualized and - in a way analogous to that found in many animals - mechanisms of control have evolved inhibiting the killing of a conspecific. There are strong indications of the existence of motivating mechanisms within the brain, e.g., in the form of neuronal circuits, that show a degree of spontaneity. The type of destructive aggression which we call war, is a product of cultural evolution. War takes advantage of the given motivational structure of man, including his fear of strangers, which develops in every baby independently of experience and makes men inclined to form closed groups and causes them to be wary of or hostile to strangers. Based on these tendencies, man underwent a process of cultural subspeciation. Groups demarcated themselves from others by custom, erecting communication barriers. The development of languages demonstrates how fast and efficient this process is. Members of the same group, during this process, were defined as the “real man,” outsiders often were to be valued less -or even considered nonhuman. On the basis of this self-indoctrination, cultural codes of conduct developed, which allowed members of other groups to be killed when groups competed for resources. A cultural fiiter of norms was established which demanded killing under defined conditions, and was superimposed upon the biological filter of norms which inhibits the killing of a human being. This results in a conflict of norms, which is universally felt as guilt, since the biological filter of norms, though superimposed, is nonetheless working, particularly in the circumstance of a personal encounter. The more advanced the technique of armament, which allows fast and distant killing, the less the inhibitions are activated. Nonetheless, ritualizations occur on the cultural level. Warfare is sometimes ritualized and conventions are developed to prevent escalation into massacres, or the wholesale destruction of the subjugated enemy. To a great extent, this is certainly a result of our inborn moral code, If nothing like this were given to man our situation would be disastrous indeed. Whether cultural evolution will, in the future, be guided by moral maxims in accord with our human nature is a deeision men must make rationally. Although a ruthless ethnocentrism may bring advantage to a warring group, this may eventually prove fatal to mankind as a whole. In the escalating competition mankind runs the danger not only of exhausting its resources, but of destroying itself with its new weapons. If the outcome were not selfdestruction but domination by one group it would impoverish the diversity of human cultures, and thus seriously cut down man's spectrum of adaptability. War fulfills certain functions, similar to those found in animals. It is mainly a mechanism for preserving and extending one's territory, and a means of getting access to scarce resources. It is therefore dangerous to consider war merely as a pathological form of human behavior because this may distract our attention from the fact that, h order to overcome war, the functions of war have to be fulfilled by nonviolent means. Cultural evolution phenocopies biological evolution, due to similarities in the selection pressures shaping its course. This allows us to define the point of the evolutionary spiral we are at currently and to predict our future course.     

Growth and social behavior of previously undernourished mice

Developing mice were growth-retarded by underfeeding of their mothers during lactation. Control mothers were well nourished throughout. All offspring were fed ad libitum from weaning till their behaviour was tested in adulthood. The undernourished mice had weight deficits at weaning of 49% compared with controls. Nevertheless, they showed partial catch-up growth thereafter, in that their absolute weight deficits decreased between weaning and adulthood. Social behaviour observations were made on pairs of mice of the same treatment group. Previously undernourished mice were slower to start attacking one another, spent more time near or in contact with one another and did less tail-rattling than their controls.     

EVERYONE AT THE TABLE: Religious Activism and Health Care Reform in Massachusetts

Using interviews with activists and Lisa Sowle Cahill's concept of participatory discourse, this article examines how the Greater Boston Interfaith Organization (GBIO) built solidarity for the 2006 Massachusetts health care reform law. The analysis explores the morally formative connections between GBIO's activist strategies and its public liturgy for reform. The solidarity generated through this interfaith coalition's activities and religious arguments contrasts with two standard types of policy discourse, economics and liberalism. Arguments for health care reform based on economic efficiency or positive rights are hampered by the lack of solidarity in U.S. political culture. GBIO's congregation‐based organizing offers a performative model of public argumentation for religious groups committed to achieving affordable, quality health care for all Americans.     

荀子社会分层的政治伦理思想及其现代价值

基于天人关系,荀子从人的自然本性和社会性出发,对其社会分层的政治伦理思想作了哲学论证。以“礼”为核心和标准,荀子把社会分层划分为社会等级分层与社会职业分层两个层面。荀子把“礼”的功能———“群”与“分”,特别是等级差别之“分”作为社会分层的手段,以最终实现社会和谐有序的政治理想。这对于我们今天构建社会主义和谐社会仍具有一定的现实意义。     

胸腔镜外科的发展、现状与思考
