This study attempted to refine the assessment of the effectance of four-year-old children through observation of their play. Two scales were developed; the first scale defined organization, involvement, and interpersonal responsiveness in play, and the second operationally defined psychosexual content of play. The validity and reliability of both scales and the inter correlations among the four major variables were explored. The results confirmed the validity and reliability of the instruments as measures of the children's effectance and important indicators of a child's capacity as a learner at age four.This research was carried out at the Dr. Martin Luther King Family Center and was supported by the Kenneth F. Montgomery Charitable Foundation in collaboration with the State of Illinois Department of Mental Health.

ABSTRACT

During the Cold War, Sharaf Rashidov became a representative of the Soviet anti-imperialist agenda, a key interlocutor with Third World leaders and a promoter of Uzbekistan as a modern and emancipated model of political, economic, social and cultural development for newly independent countries emerging from decolonization. Tashkent hosted important meetings among Soviet and Asian leaders, along with international festivals of cinema and literature, which attracted hundreds of Asian, African and Latin American intellectuals, writers, poets, journalists, trade unionists and athletes. Moreover, Uzbekistan came to symbolize the self-proclaimed compatibility between communism and Islam, offering a façade of religious freedom, tolerance and tradition combined with Bolshevik progress. The Soviet invasion of Afghanistan discredited this narrative – and Uzbekistan and (posthumously) Rashidov were humiliated in the Cotton Affair – pointing to the impact as well as the limits of Uzbek internationalism.  相似文献

In the USA the frequency of witnessed suicide, i.e. suicide committed in the presence of at least one further individual, is reported to range between 5 and 15%. As up to now no detailed analysis of this special issue has been given in the medicolegal literature, this article presents and discusses a number of cases including 8 males and 1 female (age 19-58 years, mean 41.2 years) who had all committed suicide by inflicting a gunshot to the head. In 3 cases post-mortem blood alcohol concentrations of 1.73, 1.88 and 2.23 g/kg respectively were observed. Toxicological tests produced negative results. 5 cases had a medical history of psychiatric disorder with endogenous depression in 3, chronic alcohol abuse and drug abuse with concomitant psychosis in one case each. As far as the motives were known, domestic arguments were of prevailing importance. With one exception the suicides were committed at home. In 6 cases one witness was present, in 2 cases 2 individuals and in one case 22 persons witnessed the suicide. The reported cases are discussed in comparison with the psychiatric-psychological classification according to McDowell et al. with the aim to provide a solid and comprehensive medicolegal method to distinguish between homicide and suicide. Furthermore aspects of psychiatric sequelae and psychological support of the witnesses, which are also of importance for the forensic pathologist called to the scene, are discussed.  相似文献

Reported is the case of a man killed by a neighbor with a shotgun loaded with a unusual ammunition. The cartridge contained several shots chained together by metallic wires. Such ammunition has been used for hunting purposes but is now banned, so it can be handmade only. The joined pellets produce a wound with features that are different from those of a wound made by a regular load of pellets. Several interpretive problems are caused by the unknown number of pellets contained in the shell and the effects of the wire holding the shot together.  相似文献

On the eve of Chile's transition from military to elected government, the outgoing regime enacted an electoral engineering project intended to conserve the constitutional order it encoded in 1980. An analysis of 1989 and 1993 general elections shows that the way votes are translated into seats favors, as intended, the second largest electoral block, the Chilean Right. This bias, along with the number of appointed senators and the special majorities required for constitutional amendments, gives the Right a minority veto power on any reform initiative. Moreover, the electoral system produces incentives for parties, candidates and voters that enhances this balance of power. The role that the electoral system plays in Chile therefore consolidates a limited form of democracy, rather than a liberal one.  相似文献

We consider the simplest version of a jungle economy à la Piccione-Rubinstein, wherein as many agents as goods are assumed, agents consume at most one indivisible good, and a transitive strong power relation exists. We first study the wilderness of jungle equilibria, i.e., whether they are Pareto-minimal (an allocation is Pareto-minimal if it is impossible to reduce the welfare of one agent without increasing the welfare of another). We show that jungle equilibria are not necessarily Pareto-minimal. We then study and characterize the set of Pareto-minimal jungle equilibria. Second, we tackle the case of equally powerful people, in contrast to the assumption that the power relation is asymetric. Assuming specifically a transitive weak power relation, we show that jungle equilibria exist, but that they are not always unique, nor Pareto-optimal. We also provide conditions under which those equilibria are Pareto-minimal.
