Nonparametric Bayesian inference for multivariate density functions using Feller priors

Multivariate density estimation plays an important role in investigating the mechanism of high-dimensional data. This article describes a nonparametric Bayesian approach to the estimation of multivariate densities. A general procedure is proposed for constructing Feller priors for multivariate densities and their theoretical properties as nonparametric priors are established. A blocked Gibbs sampling algorithm is devised to sample from the posterior of the multivariate density. A simulation study is conducted to evaluate the performance of the procedure.     

Understanding the Dynamics of the Individual Donor’s Trust Damage in the Philanthropic Sector

Although trust is long known to be critical to predict behaviors in a charitable context, little research has examined trust damage and its effects on giving behavior. Trust damage is an intermediate state between trust and distrust, rather than a simple reversal or extension, and can change over time. Our research explores individual donor’s trust damage through a dynamic evolution. Across the longitudinal survey, we conclude that the trust damage of pre-giving, giving, and post-giving stage plays different roles in the decision-making process. Trust damage does not play a direct role in the giving intention, but it can indirectly affect giving intention through its impact on perceived benefit and perceived risk. Individual donor’s satisfaction has a strong effect on post-giving trust or continual trust damage, which in turn positively affects future giving intention and behavior. Several important insights for practitioners in the nonprofit sector are also discussed.     

Brushes Move with Daring Spirit:Studying Ren Changjiu's Oil Paintings

正Looking at the paintings of Ren Changjiu painted during his one-year research and study at Beijing Fine Art Academy,we cannot help applauding for the progress and accomplishments he has made on the road of oil paintings exploration in such a short period of time.From his paintings,we can clearly find that the objects have gradually become blurred and fuzzy comparing to his early works

城市更新与遗产活化利用:旅游的角色与功能

建筑遗产的活化利用是城市历史街区更新的重要手段,而旅游利用则是建筑遗产活化利用的关键支持。本文在综述建筑遗产利用相关文献的基础上,总结了建筑遗产保护的思潮演变,并分析了旅游在其中的角色与功能。结论认为,建筑遗产保护正逐渐从单一的"原状保护"向多元化的"活化利用"转变。在这种活化利用中,旅游起着重要作用,它承担着建筑遗产空间关联、业态支撑的角色,而这种以旅游为目的的活化利用也提升了游客体验,增加了建筑遗产的吸引力,活化了城市空间结构,增加了城市竞争力。     

社交网络时代大学生政治参与及引导机制研究

社交网络时代,网络成为大学生政治参与的新载体,大学生通过社交网络参与政治社会生活积极性高,原因在于:通过网络参与的及时性;同辈交流自由化,长幼交流隐私化;接受信息私己性与自我满足性。因此,可构建大学生网络政治参与引导互动模型,包含动力机制、协调机制、导向机制、效能机制以及交互机制等内容。     

大学章程在大学法人化治理中的价值向度与法律限度

大学章程通过对举办者、办学者及其他利益相关者的意志与权利进行确认,并对各相关权利主体进行制度性的规约,起到了理性化的价值引导与依法治理的保障作用.在创建中国特色的现代大学制度过程中,大学章程能不能被视作一种法律,在多大范围内多大程度上发挥作用,需要理性地审视.研究以中外比较、历史比较、现实发展的视角探讨了我国大学章程的法律效力及其限度.大学章程需要基于“自主管理”的诉求,以“共治”的方式实现现代大学制度的“法治”化,以期实现大学的本质价值追求.     

弗里茨.诺依曼和德国民主法治国的构想

德国公法学家和政治学家弗里茨?诺依曼是早期法兰克福学派的外围成员。他亲历魏玛宪政危机、纳粹上台以及二战后德国政治生活重建等重大政治事件，在理论上游走于德国公法学、马克思主义和民主法治国等观念之间。他对晚期资本主义社会的分析与批判、对民主法治国观念的构想，既联系又区别于当时学界的其他学者。诺依曼探讨了以下三个递进性问题：（1）魏玛共和国为什么会失败？（2）纳粹政权的本质是什么？（3）二战之后如何重建德国的政治生活？他也由此实现了德国法治国观念迈向民主法治国观念的关键一步，并为联邦德国的二战后重建提供了基本政治框架。     

“共有地”的制度发明

"共有地"的意涵是多重的,产权、公共资源和习俗既是三种不同的理论路径,也是"共有地"界定的三个不同层次。但是,对于"共有地"的解释,不是产权、资源、习俗三种理论进路的简单叠加,而应该走向一种整体论的"彻底解释"。可以将"共有地"作为一项制度实践,揭示其"传统发明"的整体动态机制,此即"共有地"的制度发明。
