康北霍尔人的来源及历史演变蠡测

作为藏族的一个支系,康区北部的霍尔人与周围其他的藏族人群相比,在语言、体质、文化面貌等方面都有其独特之处。他们被普遍认为与蒙古族存在一定的族源关系。本文认为,康北的霍尔人的来源更有可能与元代生活在我国西北地区的黄头回鹘即撒里畏兀人有一定的关系。公元1331年,一批撒里畏兀军队迁徙至康区北部,经过与周围其他民族不断融合,逐渐发展成为藏族的一部分,但依然保留了一些撒里畏兀人的文化传统和体质特征,被其他藏族人群称为“霍尔人”。     

西双版纳傣族宗教生活的世俗化倾向--以嘎洒、勐罕、大勐龙三镇为例

如果对20世纪90年代以来西双版纳傣族的宗教生活做一个总体的回顾,就可以得出这样的结论西双版纳傣族的小乘佛教正处于日益世俗化的进程中.文章以西双版纳三个傣族乡镇的宗教生活为田野调查个案,并对这三个个案进行了比较分析,从中得出西双版纳傣族的宗教生活在不同方面、不同程度上都存在着世俗化的倾向.本文以此为切入点,来探讨社会转型时期西双版纳傣族的文化价值取向.     

建设环境友好型社会的伦理思考

人作为一种关系中的存在,对于环境的独立性始终不能摆脱其对环境的依赖性,当人认识到这种必然性时,人与环境的伦理关系就产生了.作为环境干预主体的政府、企业和普通民众在这种自我约束、自我管理的伦理建构中应该明确各自应有之责任和发挥各自应有之作用,从而共同构建环境友好型社会.     

对撒拉族女童教育状况的人类学调查与研究

撒拉族青少年的教育状况,尤其女童教育状况自20世纪80年代初以来一直不容乐观,备受关注。本文从教育人类学的角度,参考先前学者的调查结果,结合当地实际,对新世纪撒拉族女童的教育状况进行了调查与分析。在分析了影响撒拉族女童教育的主、客观两个方面的原因后,作者提出少数民族女童的教育状况,不能仅仅凭借学校教育为本来做结论,与家庭教育有关的少数民族"本土文化"教育也不容忽视。     

Sourcing with Deferred Payment and Inspection under Supplier Product Adulteration Risk

We study the deferred payment and inspection mechanisms for mitigating supplier product adulteration, with endogenous procurement decision and general defect discovery process. We first derive the optimal deferred payment contract, which reveals that either entire or partial deferral can arise, depending on the moral hazard severity and the information accumulation rate. Because of the supplier's incentive to adulterate, the optimal procurement quantity under deferred payment generally is smaller than the first‐best quantity. We then investigate the inspection mechanism and characterize the equilibrium. We find that under the inspection mechanism, the optimal procurement quantity is no less than the first best. A comparison between these two mechanisms shows that the deferred payment mechanism generally can outperform the inspection mechanism when either the market size is small or the profit margin is low. However, we find that these two mechanisms can also be complementary, for which we characterize a necessary condition.     

A visualization method measuring the performance of biomarkers for guiding treatment decisions

Biomarkers that predict efficacy and safety for a given drug therapy become increasingly important for treatment strategy and drug evaluation in personalized medicine. Methodology for appropriately identifying and validating such biomarkers is critically needed, although it is very challenging to develop, especially in trials of terminal diseases with survival endpoints. The marker‐by‐treatment predictiveness curve serves this need by visualizing the treatment effect on survival as a function of biomarker for each treatment. In this article, we propose the weighted predictiveness curve (WPC). Based on the nature of the data, it generates predictiveness curves by utilizing either parametric or nonparametric approaches. Especially for nonparametric predictiveness curves, by incorporating local assessment techniques, it requires minimum model assumptions and provides great flexibility to visualize the marker‐by‐treatment relationship. WPC can be used to compare biomarkers and identify the one with the highest potential impact. Equally important, by simultaneously viewing several treatment‐specific predictiveness curves across the biomarker range, WPC can also guide the biomarker‐based treatment regimens. Simulations representing various scenarios are employed to evaluate the performance of WPC. Application on a well‐known liver cirrhosis trial sheds new light on the data and leads to discovery of novel patterns of treatment biomarker interactions.

Stochastic comparisons on sample extremes of dependent and heterogenous observations

Stochastic comparison on order statistics from heterogeneous-dependent observations has been paid lots of attention recently. This paper devotes to investigating the ordering properties of order statistics from dependent observations. We derive the usual stochastic order for sample minimums and the second smallest order statistic, the dispersive order and the star order for minimums of samples having proportional hazards and Archimedean survival copulas. Similar ordering results are also obtained for maximums and the second largest order statistic of samples having proportional reversed hazards and Archimedean copulas. Several examples illustrating the main results are presented as well.     

论编辑现代化进程中编辑主体的继续教育

随着信息技术的发展和办刊条件的改变,编辑现代化的水平也越来越高,但由于我国的国情和历史因素,在我国编辑现代化不断发展的进程中,我国出版行业编辑主体的现代化程度已经不能适应整个出版行业的发展,继续教育是编辑主体适应编辑现代化发展,实现编辑主体现代化的必由之路.     

浅析中国城市的都市区划研究

城市总是在发展的过程中,城市地域在不断地扩大,和周边的联系在不断强化,相对稳定的区划格局很显然不能持续反映城市体系的变化,更不能长久地促进以城市为核心的整个区域的发展,所以发达国家积极探讨设立独立于行政区外的地域概念实体来解决这个矛盾,美国、加拿大等发达国家通过"都市区"来解决行政区划和城市发展脱节的问题.     

学院制模式下有关财务管理问题的探讨

学院制管理模式下,更有必要对校院两级的财务权限加以界定,以明确各自的权、责、利。同时,在清晰学院制真正内涵的前提下,建立有效的财务核算体系,确立科学、合理的经费分配办法,制定以绩效考核为主的财务核算模式,健全校院两级的财务监督分析体系,确保学院制模式下财务运行的高效。
