Bayesian analysis of human movement curves

Summary.  We consider the Bayesian analysis of human movement data, where the subjects perform various reaching tasks. A set of markers is placed on each subject and a system of cameras records the three-dimensional Cartesian co-ordinates of the markers during the reaching movement. It is of interest to describe the mean and variability of the curves that are traced by the markers during one reaching movement, and to identify any differences due to covariates. We propose a methodology based on a hierarchical Bayesian model for the curves. An important part of the method is to obtain identifiable features of the movement so that different curves can be compared after temporal warping. We consider four landmarks and a set of equally spaced pseudolandmarks are located in between. We demonstrate that the algorithm works well in locating the landmarks, and shape analysis techniques are used to describe the posterior distribution of the mean curve. A feature of this type of data is that some parts of the movement data may be missing—the Bayesian methodology is easily adapted to cope with this situation.     

应对企业人力资本投资风险的对策探析

改革开放以后,随着我国社会主义市场经济的深入发展,越来越多的企业把人才储备看作企业竞争力的核心所在。但同物资资本投资一样,人力资本投资也存在着风险,而且由于人力资本本身的特殊性,人力资本投资还具有许多特有的风险。本文先是简要地介绍了人力资本的内涵及起源,然后从企业的角度分析人力资本投资存在的各类风险,并以此为基础,提出应对这些企业人力资本投资风险的相应措施。     

欧盟对中东北非政策调整之我见

法、德两国领导人更替后，欧洲同美国的关系恢复到伊拉克战争之前的状态，但是欧盟主要大国及欧盟本身对中东北非地区的政策仍不同于美国。2003年以来，该地区一系列事件发生后，欧盟及欧洲各大国决策者和学者对以往的政策做出评估或修改：比以往更强调坚持长期的经济发展政策；由下而上改变政权结构；推动中东北非国家进入国际体系；提高治理能力及保障人身安全等，从而达到“以发展促安全、以安全促发展”之目的。

西方人力资本理论的发展脉络

西方人力资本思想最早可以上溯到古希腊时期,经过漫长的演变,直到二十世纪六十年代才最终形成人力资本理论。人力资本理论从一开始就表现为两种研究思路,即宏观研究思路和微观研究思路,八十年代中期以后又取得了新的发展。     

Transforming Social Work Curricula: Institutional Supports for Promoting Sustainability

Due to the centrality of human rights and social justice in the profession, social work must collectively take a stand on ecological degradation and the climate crisis. Overall, social work education's engagement with issues of sustainability and an expanded ecological justice perspective has been peripheral and piecemeal. It is crucial that social work education expand opportunities to prepare social workers to respond to the global environmental crisis. This conceptual paper considers strategies for integrating environmental content in social work curricula and addresses the essential role of institutional supports for curricular change and professional development focused on sustainability. The role of institutional supports to advance curricular change to respond to environmental crises and promote sustainability is highlighted, along with specific examples from the authors' home institution, including (1) institutional commitment and culture, (2) curricular supports and guidelines, and (3) interdisciplinary faculty development.     

贺麟王安石研究中的心学思想

文章从心论和性论二个方面,说明贺麟对王安石心学思想的抉发。心论方面,以黑格尔哲学为出发点,着力阐发王安石“建立自我”的思想。性论方面,认为王安石先主性善恶混,然后过渡到性善论。性善恶混可以强调后天人为努力的重要性。而最后归本性善论,是为了高扬精神的能动力量,心的将价值理想和深厚的文化蕴积融摄为一,以价值带动文化蓄蕴这种功能。以上诠释,是他新心学哲学理论的鲜明体现。     

从自利假设到社会财富的增加

如果经济学理论当中存在公理的话 ,当首推斯密的“经济人”假设 ,即自利假设。经济科学发展到今天 ,仍然没有能够抛弃自利的假定 ;经济实践的发展过程中 ,自利假定不仅引发了对财富变化的思考 ,而且对产权制度的安排亦颇多启发。当基于自利的财富变化不能朝着有利的方向发展时 ,制度的革新就成为必然     

西藏商务代表团的美国之行与美国对西藏政策的转变

解放战争时期的1947-1948年间,西藏当局派出以孜本·夏格巴为首的西藏商务代表团,赴印度和美国、英国等国游说西藏独立,但是无功而返。围绕对于该代表团的接待问题,南京国民政府与美国政府就西藏的地位问题发生争执。美国政府最后尊重了中方的立场,承认西藏是中国领土的一部分。整个事件的处理过程表明,在冷战的大背景下,当南京政府在全中国的统治行将覆灭之际,美国政府对于西藏的政策开始发生转变。     

民事诉讼当事人自由权简论--以人权保障为视角

人权具有普遍性。自由权的人权在民事诉讼中表现为起诉的自由、上诉的自由、选择一审管辖法院的自由、应诉的自由、撤诉的自由、选择审理程序的自由、合意停止诉讼程序的自由、要求公开或不公开审理的自由、合意要求法院调查取证、合意选择鉴定人和合意要求调解的自由、辩论的自由、自认的自由和认诺的自由等。我国民事诉讼无论在制度的层面还是在实践的层面离人权的标准都还有较大的差距。
