儿童发展指标体系建构的理论基础

社会转型期,国家与儿童的关系是国家与个人关系框架中最基础,最重要,也最具社会经济政治涵义的关系。为此,部分国际组织和国家已经着手开发儿童发展与福利综合评价指数。儿童发展指标是对儿童群体的生存与发展状况进行的具有较强科学性的概括性度量。本文对建构儿童发展指标体系涉及的相关理论作了初步介绍和评述,为推进儿童发展指标体系研究提供了新的视角和线索。

Agency Problems between Managers and Employees in Nonprofit Organizations: A Discrete Choice Experiment

Most principal–agent literature of nonprofit organizations has focused on the relationship between board members and managers. However, in addition to the role as an agent of the board, the manager also performs a role as principal with respect to the nonprofit employees. By using a discrete choice experiment, we identify the objectives of managers and employees in nonprofit organizations and assess the presence of agency problems in this relationship. Our sample consists of 76 headmasters, 161 teachers, and 39 administrative employees in 74 secondary nonprofit schools in Belgium. We find that the six objectives set out in the experiment play an important role for both headmasters and subordinate staff. However, the results also indicate that some of these objectives are significantly more important for the headmasters. In sum, our results suggest that agency theory and stewardship theory are not necessarily in conflict with each other but can be combined into a more general governance framework for nonprofit organizations. Consequently, we argue that incentive structures that incorporate different types of objectives can facilitate the recruitment and retention of employees in nonprofit organizations.     

“登山则情满于山,观海则意溢于海”——创作思维特征的精妙阐释

自<文心雕龙>问世以来,注家蜂起,歧见迭出.其中对作为创作总论的<神思>篇的解说更是众说纷纭,见仁见智.文章在细读文本和博取前辈诸家合理内核的基础上,对"神思"作出新的阐释,探求这一艺术构思论的理论价值.认为"神思"指的是在创作构思过程中,作者所具有的一种不受时空限制的自由艺术想象,它作为一种复杂的思维活动,亦呈现出四大特点.     

官邸制的价值意蕴与体系构建

自从党的十八届三中全会提出探索实行官邸制的设想，官邸制一度成为新闻界、学术界关注的热门话题。由于官邸制在我国尚属新鲜事物，官邸制的理论研究严重不足，什么是官邸及官邸制以及实行官邸制对我国官员住房制度改革会产生怎样的意义等问题尚不清晰，而官邸制的制度构建更是一次任重而道远的理论考验，其中官邸的来源、规格、经费管理、适用主体范围以及附属保障措施的构建成为官邸制的核心。探索出完善、科学的官邸制关系到新时期改革的实施乃至成败。     

On Shortest k-Edge-Connected Steiner Networks in Metric Spaces

Given a set of points P in a metric space, let l(P) denote the ratio of lengths between the shortest k-edge-connected Steiner network and the shortest k-edge-connected spanning network on P, and let r = inf l(P) P for k 1. In this paper, we show that in any metric space, r 3/4 for k 2, and there exists a polynomial-time -approximation for the shortest k-edge-connected Steiner network, where = 2 for even k and = 2 + 4/(3k) for odd k. In the Euclidean plane, and .
