近年来台湾主要政党与青年选民群体的互动分析

近年来,台湾主要政党依据青年选民群体的政治文化特征,纷纷采取具体措施来吸引青年选民支持.在平时,主要依靠建立青年组织体系,累积青年的政党认同,在选举时期,则围绕政党形象营销、候选人形象营销、政策营销三个主轴,全面性地争取青年选票.在台湾未来的选举中,针对青年选民群体,主要政党之间的竞争将变得日益激烈.     

Reciprocal Family,Friendship and Church Support Networks of African Americans: Findings from the National Survey of American Life

This study examined reciprocal support networks involving extended family, friends and church members among African Americans. Our analysis examined specific patterns of reciprocal support (i.e., received only, gave only, both gave and received, neither gave or received), as well as network characteristics (i.e., contact and subjective closeness) as correlates of reciprocal support. The analysis is based on the African American subsample of the National Survey of American Life. Overall, our findings indicate that African Americans are very involved in reciprocal support networks with their extended family, friends and church members. Respondents were most extensively involved in reciprocal supports with extended family members, followed closely by friends and church networks. Network characteristics (i.e., contact and subjective closeness) were significantly and consistently associated with involvement with reciprocal support exchanges for all three networks. These and other findings are discussed in detail. This study complements previous work on the complementary roles of family, friend and congregational support networks, as well as studies of racial differences in informal support networks.

一位法国人类学家在中国的田野实践——法国人类学家庄雪婵专访

庄雪婵副教授在访谈中谈到了其作为一名法国人类学家在中国进行田野实践的过程。在研究过程中,她深受法国人类学结构主义重要代表人物路易。杜蒙的影响,她运用杜蒙的“个人主义”理论对中国社会中的“个人”与“整体”关系进行了深入分析,她提出,在中国,虽然现代的音乐活动(如摇滚乐队)和传统的音乐活动(如“京剧票友”)在风格上截然不同,但是它们在结构上却存在着一定的相似性。另外,她也根据自己的跨文化研究经验,指出一个人类学家在田野中必须保持自己独立的思想、理性的思维,并做到不以自己的文化来衡量“他者”的文化。同时,她也对现代化进程中传统文化的急速消逝表现出了一个人类学家的忧虑,她呼吁人类学家应该尽快到乡村把这些濒临消逝的传统文化记录下来。

地区一体化与冲突管理机制相关性研究:基于欧盟的实证分析

当前,欧盟实现了具有重要意义的政策创新.欧盟一体化进程的推进,与地区冲突管理模式创新之间有着紧密的相关性.欧盟主导处理冲突的"欧洲化"模式,代表着一种进程,即"将冲突的最终结果,与一体化的水平或者说欧洲处理冲突的其他结构联结在一起".欧洲的整合已成为二战以后该地区秩序稳定的重要因素.通过一体化,欧盟为寻求地区冲突的解决探索了一条可供选择的道路.     

地方立法公众参与的概念、主体与价值

为探讨地方立法公众参与制度的建立与完善,运用归纳分析法、实证分析、比较、价值分析等方法界定地方立法、公众参与、地方立法公众参与和公众主体,论证了地方立法公众参与的价值.认为地方立法公众参与是指作为公众的自然人、自然人体现的法人、社会团体直接参与地方立法的制度,其具有地方法规正当性、适应性、权威性的价值.     

战后菲律宾土地改革、政策变迁与农业发展

纵观战后菲律宾农业发展过程,其劳动生产率和土地生产率均增长缓慢。土地结构倾斜、土地改革进程缓慢,经济政策的扭曲是阻碍菲律宾农业长期增长和发展的两大主要原因。菲律宾要摆脱农业发展的困境,以下几个方面需要重视:逐步取消对农业生产的投入产出部门的扭曲管制;减少在贸易、价格方面的管制;加强基础设施建设投入、加强农村地区的人力资源训练、加强农业技术的研发与推广。     

双循环新发展格局下中国双向直接投资研究

构建以国内大循环为主体、国内国际双循环相互促进的新发展格局,是对未来中国经济发展路径做出的重大战略部署,作为连接国内国际双循环的纽带,双向直接投资的发展战略和路径面临重塑和调整。研究认为,应当以推动新时代科技创新和产业升级为目标,提高双向直接投资的质量,畅通供应链和产业链; 以“一带一路”倡议为依托,通过更高水平的双向投资带动中国与沿线国家贸易水平的提高; 建设高水平自贸区和自贸港,提高对外开放标准,更高质量吸引外资,提升参与国际大循环的技术含量和自主性; 在畅通要素流动领域,建立更加完善的现代化物流体系,建设更高标准的要素流通市场体系,降低制度性交易费用,提高生产率和对高质量外资的吸引能力。     

Optimization problems with color-induced budget constraints

In 1984, Gabow and Tarjan provided a very elegant and fast algorithm for the following problem: given a matroid defined on a red and blue colored ground set, determine a basis of minimum cost among those with k red elements, or decide that no such basis exists. In this paper, we investigate extensions of this problem from ordinary matroids to the more general notion of poset matroids which take precedence constraints on the ground set into account. We show that the problem on general poset matroids becomes -hard, already if the underlying partially ordered set (poset) consists of binary trees of height two. On the positive side, we present two algorithms: a pseudopolynomial one for integer polymatroids, i.e., the case where the poset consists of disjoint chains, and a polynomial algorithm for the problem to determine a minimum cost ideal of size l with k red elements, i.e., the uniform rank-l poset matroid, on series-parallel posets.
