慈善捐赠是多元化的民事法律行为,是自愿、无偿、单务和不可任意撤销的捐赠。慈善捐赠的标的物种类繁多,可为有形财产,可为无形财产。捐赠财产的归属并不单一,应根据捐赠行为属性等因素进行具体分析。受赠对象既可为组织,亦可为个人,但应以捐赠人对受赠人不负有法定救助义务为限,且必须用作有益于社会或个人的事情。慈善捐赠的外延极大,因此须要进行类型化的分析。 相似文献

Accounts of jackpot winners and big gambling wins are common in Swedish newspapers. Analysis of over 2000 such newspaper articles reveals that their content is structured according to specific themes and cultural topics. Four such topics are identified: wealth as a test of morals and character, the social impact of wealth, the just and good world, and luck and the occult. Culturally structured narratives like these—which elaborate on mythological and moralistic schemes of good and evil, rewards and punishments, and which concern questions of human nature and social values—have a long history in folk tradition and in Christian moral teachings. Jackpot wins provide a discursive realm for moral and existential questions that, to some extent, fills a void left by the decline of traditional folklore and formal religion. Apparently, this discourse stimulates interest in games and constitutes one of the cultural roots of contemporary gambling. 相似文献

We analyse the profile of potential emigrants from Albania using data from the Central and Eastern Europe Eurobarometer in
1992. Respondents were asked to rate on a four-point scale the likelihood that they would go to live in Western Europe. Our
results show that intention to emigrate is correlated positively with males, education and certain occupations, and negatively
with age. There is little relation between emigration and income. Those who support the introduction of a free market in Albania
are also more likely to emigrate than those who do not.

The purpose of this article is to construct a theoretical framework characterizing the interactions among economic development,
ecosystem equilibrium and possible population decline, and to discuss the population dynamics in the very long run. In our
framework, economic activities bridge population and environment. On the one hand, human beings reform the environment through
economic activities; on the other hand, economic activities decrease environmental resilience and increase the possibility
of an environmental change in a discontinuous and irreversible pattern, as described in Arrow et al. (1995). Furthermore,
a highly developed economy also causes over-specialization of human adaptation, which tends to exaggerate the impact of an
environmental change on human population size.

The main objective of this paper is to develop an exact Bayesian technique that can be used to assign a multivariate time series realization to one of several autoregressive sources, with unknown coefficients and precision, that might have different orders. The foundation of the proposed technique is to develop the posterior mass function of a classification vector, in an easy form, using the conditional likelihood function. A multivariate time series realization is assigned to the multivariate autoregressive source with the largest posterior probability. A simulation study, with uniform prior mass function, is carried out to demonstrate the performance of the proposed technique and to test its adequacy in handling the multivariate classification problems. The analysis of the numerical results supports the adequacy of the proposed technique in solving the classification problems with multivariate autoregressive sources. 相似文献

综合语义、语法和语用三个平面对双宾语句进行重新定义,然后按照这个定义对古代汉语、现代汉语以及英语里的双宾语动词进行重新分类描写;同时进行汉语内部的历时比较,汉语和英语的共时对比,发现:古汉语中表"为动"服务义的双宾语句在现代汉语中已基本消失;现代汉语中比较常见的表"获取"义的双宾语句在英语中基本没有;而表"制作"服务义的双宾语句在英语中却很常见。 相似文献

Several authors have proposed approximations to percentage points required for testing certain hypotheses associated with the multiplicative interaction model. Alternative approximations based on the asymptotic joint distribution of the characteristic roots of a noncentral Wishart matrix are proposed in this paper. The type I error rates of the resulting tests and the existing procedures are then compared using Monte Carlo methods. 相似文献

This paper examines a wide variety of forms, and full histories, of family structure to test existing theories of family
influences and identify needs for new theories. The focus is on links between childhood family structure and both completed
schooling and risk of a nonmarital birth. Using a 27-year span of panel (PSID) data for U.S. children, we find that: (a) change
is stressful, (b) timing during childhood is relevant, (c) adults other than parents are important, and (d) two more recently
studied family structures (mother-with-grandparent(s) and mother-with-stepfather) do not fit the molds of existing theories.
The findings suggest that new theories should consider allocation of resources and reasons people group into family structures.

The quadratic discriminant function is commonly used for the two group classification problem when the covariance matrices in the two populations are substantially unequal. This procedure is optimal when both populations are multivariate normal with known means and covariance matrices. This study examined the robustness of the QDF to non-normality. Sampling experiments were conducted to estimate expected actual error rates for the QDF when sampling from a variety of non-normal distributions. Results indicated that the QDF was robust to non-normality except when the distributions were highly skewed, in which case relatively large deviations from optimal were observed. In all cases studied the average probabilities of misclassification were relatively stable while the individual population error rates exhibited considerable variability. 相似文献
