Therapists bring their own initiative, interest, and wonder—their professional curiosity—into treatment sessions. Some children and adolescents pull away in reaction to this curiosity, bristling or withdrawing, if only for a moment. This can happen abruptly, even in response to the first hello, but most often it occurs subtly, over the course of treatment. These children and adolescents may be replaying the ruptures in relationships they experienced when they have expressed their own initiative and curiosity to important others in their lives. Therapists need to utilize opportunities to understand the dynamics, explore where the original ruptures may have occurred, and bring the experience into therapeutic focus. Case vignettes illustrate these dynamics.  相似文献

工程设计现在已发展到全数字化阶段,能使设计、制造一体化过程得以实现的核心是三维几何模型,二维投影图已不是这一过程所必需的文件.因此,在总结和继承原教改成功经验的基础上,我们对传统的工程图学课程进行改革,突出"三维"和"设计"两个重点,形成了现代工程设计图形学(MEDG)课程体系.  相似文献

文章认为,“祖骚宗汉”实质上是元人不满于律赋的偏尚俳偶与文赋的倾于理趣,却又缺少情感或藻彩而提出的一个辞赋革新的口号。在这面旗帜下,元赋作家学习楚辞,宣泄失志之悲,驰骋想象,展开入地升天的描写;也学习汉赋的颂美皇家和铺陈讽谏。这些努力强化了元赋的抒情性和生动性,复兴了古赋的宏大气势,使之获得较高的文学价值,并奠定了明清辞赋以古为主的格局。元赋的不足是思想境界稍欠高迥,也缺少全新的创造。  相似文献

Lack of information about technology and prices often hampers the empirical assessment of the profit maximization hypothesis (viz. by measuring the degree of profit efficiency). The non-parametric Data Envelopment Analysis (DEA) methodology can deal with such incomplete information. We exploit the implicit but largely neglected profit interpretation of the DEA model that builds on assumptions of monotone and convex production possibility sets. We show how its embedded assessment of necessary conditions for profit maximization can be strengthened given partial information in the form of monetary sub-cost/-revenue data (that are often easier obtained than the pure quantity data). Finally, we argue that a ‘mix’ efficiency analysis is naturally complementary to such a profit efficiency analysis. An application to German farm types complements our methodological discussion. By using non-parametric statistical tests, we further demonstrate the potential of the non-parametric approach in deriving strong and robust statistical evidence while imposing minimal structure on the setting under study. In particular, we look for significant efficiency variation over regions.  相似文献

The collective approach to household consumption behavior tries to infer from variables supposed to affect the general bargaining position of household members information on the allocation of consumptions goods and tasks among them. This paper investigates the extension of previous work to the case where children may be considered as a public consumption good by the two adult members of a household. The main question being asked is whether it is possible to retrieve from the aggregate consumption behaviour of the household and the relative earnings of the parents information on the allocation of goods between them and children. This alternative approach to the estimation of the ‘cost of children’ is contrasted with the conventional approach based on a ‘unitary’ representation of and demographic separability assumptions on household consumption behaviour.

The article studies the causal effect of trust on the willingness to pay higher taxes to help the needy in a sample of 29 countries of Eastern and Southern Europe, and the former Soviet Union and Mongolia. It is hypothesized that interpersonal trust leads to a greater willingness to pay taxes to help the needy since (i) trust increases the likelihood of helping strangers; (ii) trust fosters solidarity and cooperation when working to solve common problems in society; and (iii) trust reduces suspicion with respect to the perceived misuse of redistributed money. Three key findings are that the more people trust each other, the more they are ready to support the welfare state; the effect of trust on welfare state support holds even in a contextual environment characterized by rather lower levels of trust and relatively underdeveloped systems of redistribution; and higher individual‐level trust fosters tax morale and helps deter tax evasion.  相似文献

In their recent paper (1977, Social Science Research, 6, 188–196), Kenny and Rubin offer an interpretation of “chance” in Guttman scaling. Their approach is based on the matrix of probabilities pij, giving the chance that the ith respondent passes the jth item. It is shown that their interpretation of chance in fact corresponds to a stochastic model of a perfect unidimensional scale. An alternative condition for chance based on the matrix of pij's is proposed. This is then proved to be equivalent to the usual interpretation.  相似文献
