托马斯·阿奎那论宗教与政治

作为神学家和西方教会的代言人,阿奎那深入讨论了宗教与政治的关系问题,包括如何协调教权与王权的关系、如何对待异教徒、如何对待叛教者等。针对不同情况,他的政策也不相同,但其目的只有一个:在保持基督教国家内部稳定的前提下,打击异教力量和异端分子,维护和加强教会的势力。     

Evaluation: Stakeholder-focused Criteria

Identifying and selecting suitable criteria is an important consideration in evaluating the performance of public sector organizations. Which criteria are chosen, and how they are weighted, will depend largely on the perspective being taken; different stakeholders (for example, clients, providers or commissioners) are likely to emphasize different criteria. In this paper a number of criteria are identified and an argument is developed to indicate which criteria are likely to be valued by various stakeholders. Furthermore, a number of approaches and mechanisms for evaluation are identified and the links between these, the criteria appropriate to them and the various stakeholders are made explicit. Finally, the issue of politics and the distribution of power between the stakeholders is addressed with a call for greater explicitness in using and balancing criteria (for example, as between professionals and the intended beneficiaries of services). In this way, while recognizing the inherent political nature of performance evaluation, the planning and implementation of services may be improved by a more mutually informed approach to evaluation.     

Differences in white-nonwhite community mental health center service utilization patterns

Routinely collected computerized data were used to study the process of service delivery in terms of admission patterns, type and quantity of services rendered, and status at termination for whites and nonwhites in two community mental health centers. Social area analysis techniques were employed to control for socio-economic status, ethnicity and life style variables, and an epidemiologic model was used to analyze admission and service delivery rate differences. It was found that nonwhite admission rates were at least twice as great as white rates. Service delivery rates to the population at large were considerably greater for nonwhites than for whites. Delivery of direct services within the centers differed for whites and nonwhites, but no consistent trends emerged when types and amounts of services rendered were analyzed, controlling for sex, ethnicity, age, diagnosis and social area. Disruption of care indices were greater for nonwhites than for whites. Highlighted were some of the complexities involved in interpreting results of utilization studies.     

Minimum power assignment in wireless ad hoc networks with spanner property

Power assignment for wireless ad hoc networks is to assign a power for each wireless node such that the induced communication graph has some required properties. Recently research efforts have focused on finding the minimum power assignment to guarantee the connectivity or fault-tolerance of the network. In this paper, we study a new problem of finding the power assignment such that the induced communication graph is a spanner for the original communication graph when all nodes have the maximum power. Here, a spanner means that the length of the shortest path in the induced communication graph is at most a constant times of the length of the shortest path in the original communication graph. Polynomial time algorithm is given to minimize the maximum assigned power with spanner property. The algorithm also works for any other property that can be tested in polynomial time and is monotone. We then give a polynomial time approximation method to minimize the total transmission radius of all nodes. Finally, we propose two heuristics and conduct extensive simulations to study their performance when we aim to minimize the total assigned power of all nodes.

近一百年来现代化进程中的中国乡村—兼论乡村振兴战略中的“乡村”

建设什么样的乡村、怎么建设乡村,是近代以来中华民族面对的一个历史性课题。 在近百年中国现代化进程中,乡村不断衰败凋敝,这跟近百年来我国所选取的经济发展道路不无关系,更与人们对于“乡村冶和“乡村发展冶的认识紧密相关。 在相当长的一个历史时期内,人们简单地将“乡村冶与“农业冶、“乡村发展冶与“农业发展冶相提并论。 如果不能将乡村视为一个社会的概念,并着力乡村社会建设,即便在经济发展上用尽全力,也将事倍功半。     

动词复制句中的附加语控制

动词复制句（Verb－Copying Construction，VCC）是一种在汉语口语中经常使用的结构，用符号可以简单地表示为S＋VP1＋VP2，动词V2是动词V1的拷贝。这种结构本身具有独特的句法语义特征，也具有不同的句法变体。在其进行句法运算时，两个动词性结构首先独立运算，VP1作为附加语，VP2作为主句成分进入句法推导。通过附加语侧向移位、附加合并以及主题化特征核查等句法操作形成语言表达式。其句法变体的不同构型是因为不同的控制类型造成的。     

土耳其中等强国外交的现实性和可能性

进入新世纪以来,随着土耳其经济的快速发展,其政治与外交政策也在发生变化。尤其在正义与发展党执政后,依托中东格局进入旧已破、新未立的转型之机,逐步形成中等强国型的外交战略。本文从土耳其所具有的现实条件和制约因素两个方面分析该外交战略构想的现实性和可能性。     

Testing the Equality of Two Exponential Distributions

This paper proposes an overlapping-based test statistic for testing the equality of two exponential distributions with different scale and location parameters. The test statistic is defined as the maximum likelihood estimate of the Weitzman's overlapping coefficient, which estimates the agreement of two densities. The proposed test statistic is derived in closed form. Simulated critical points are generated for the proposed test statistic for various sample sizes and significance levels via Monte Carlo Simulations. Statistical powers of the proposed test are computed via simulation studies and compared to those of the existing Log likelihood ratio test.
