赫斯和马克思是生长在同一个时代和社会背景下有着相近思想兴趣的两个人,因为都有着对当时社会中人类苦难的特别关注与极度怜悯,而有了寻找苦难根源及寻求改变当时人类苦难之良方的志向,他们一生都在为人类的解放而奋斗;可以说"人道问题意识"是他们心头共同的用一生的行动探寻和思索的问题意识。如果再追问他们是如何探寻"人道问题"的,则发现他们一直在试图克服"受苦者的目光",即试图解决人的个体存在与类存在之间的矛盾。 相似文献

In many clinical trials, biological, pharmacological, or clinical information is used to define candidate subgroups of patients that might have a differential treatment effect. Once the trial results are available, interest will focus on subgroups with an increased treatment effect. Estimating a treatment effect for these groups, together with an adequate uncertainty statement is challenging, owing to the resulting “random high” / selection bias. In this paper, we will investigate Bayesian model averaging to address this problem. The general motivation for the use of model averaging is to realize that subgroup selection can be viewed as model selection, so that methods to deal with model selection uncertainty, such as model averaging, can be used also in this setting. Simulations are used to evaluate the performance of the proposed approach. We illustrate it on an example early‐phase clinical trial. 相似文献

音乐考级是对音乐能力进行的分级考试。黄山市作为皖南山城,具有浓厚的徽州文化底蕴,在当地老百姓的观念中学习艺术是旁门左道,自从十年前第一个音乐考级点建立起,至今已有三个考级单位,参与培训并获得考级证书的学员近万人。极大程度上推动了黄山市素质教育的发展,更新了老百姓的传统观念。本文通过对黄山市音乐考级现状的调查与分析,了解本市音乐考级这一机制的运行情况,总结音乐考级带来的成效以及存在的不良发展趋向,提出解决弊端的方法并对黄山市音乐考级未来发展提出建设性的建议。 相似文献

Participants were 109 American college students studying Chinese in a study-abroad programme in Beijing. Following Kelley and Meyer, intercultural competence was defined as cross-cultural adaptability involving four dimensions (emotional resilience, flexibility/openness, perceptual acuity and personal autonomy) and was measured with a survey. A language contact questionnaire was used to document the amount of time spent on social activities. Language proficiency was measured with a standardised Chinese test. Results revealed that intercultural competence and language contact combined explained 37.7% of the proficiency gains. Language contact had direct effects on proficiency, but intercultural competence had indirect effects, mediated by language contact. 相似文献

ABSTRACTIn this paper, we propose an adaptive stochastic gradient boosting tree for classification studies with imbalanced data. The adjustment of cost-sensitivity and the predictive threshold are integrated together with a composite criterion into the original stochastic gradient boosting tree to deal with the issues of the imbalanced data structure. Numerical study shows that the proposed method can significantly enhance the classification accuracy for the minority class with only a small loss in the true negative rate for the majority class. We discuss the relation of the cost-sensitivity to the threshold manipulation using simulations. An illustrative example of the analysis of suboptimal health-state data in traditional Chinese medicine is discussed. 相似文献

动物和人一样,也具有不同的秉性。以动物喻人,自古即有。从辩证的角度看,动物秉性自然有好的一面,也有坏的一面。这里我们借助动物思考人生,专门探讨动物秉性中一些好的品质,狗-无比忠诚;猪-难得糊涂;狼-勇敢合作的典范;牛-勤劳奉献精神;狐狸-聪明智慧的象征;龟-勤恳踏实的榜样。可见,动物的许多秉性亦给人生带来诸多的启示,值得人们以思考和学习。 相似文献

Abstract This study examines the commitment of social work in various countries to its declared dual missionenhancing individual well-being and promoting social justice. It does so by examining the mode of practice preferences of graduating BSW students from seven countries. Based on cluster analysis, three distinct subgroups of students with particular patterns of preferences were found: a generic group, a direct/micro group, and a macro group. The distribution of students among these groups differs between country cohorts. While each of the clusters was to be found in all the countries studied, in three country cohorts, a majority of students belonged to the generic group and a considerable number sought to engage in macro practice, reflecting a commitment to the profession's dual focus. The majority of the students within the remaining country cohorts preferred micro practice and were far less willing to adopt macro level practices. 相似文献

Methods for a sequential test of a dose-response effect in pre-clinical studies are investigated. The objective of the test procedure is to compare several dose groups with a zero-dose control. The sequential testing is conducted within a closed family of one-sided tests. The procedures investigated are based on a monotonicity assumption. These closed procedures strongly control the familywise error rate while providing information about the shape of the dose-responce relationship. Performance of sequential testing procedures are compared via a Monte Carlo simulation study. We illustrae the procedures by application to a real data set. 相似文献

在公立学校未能提供足够的学校教育服务的情形下,为实现全民教育这一国际目标,印度政府采取了公私合作伙伴关系(以下简称PPP)的形式,提高对私营部门的利用率,以期改善基础教育服务供给和资金投入,并随着社会对教育需求的发展,不断推出新的PPP行动计划,这对于PPP办学模式在国际基础教育领域的推广具有重要意义。 相似文献
