Computing A-optimal and E-optimal designs for regression models via semidefinite programming

In semidefinite programming (SDP), we minimize a linear objective function subject to a linear matrix being positive semidefinite. A powerful program, SeDuMi, has been developed in MATLAB to solve SDP problems. In this article, we show in detail how to formulate A-optimal and E-optimal design problems as SDP problems and solve them by SeDuMi. This technique can be used to construct approximate A-optimal and E-optimal designs for all linear and nonlinear regression models with discrete design spaces. In addition, the results on discrete design spaces provide useful guidance for finding optimal designs on any continuous design space, and a convergence result is derived. Moreover, restrictions in the designs can be easily incorporated in the SDP problems and solved by SeDuMi. Several representative examples and one MATLAB program are given.     

The heterogeneous impact of pension income on elderly living arrangements: evidence from China’s new rural pension scheme

This paper investigates the impact of pension income on living arrangements of the elderly. Taking advantage of a unique opportunity due to the recent establishment and expansion of the New Rural Pension Scheme in China, we explicitly address the endogeneity of pension status and pension income through a fixed-effect model with instrumental variable approach by exploiting exogenous time variation in the program implementation at county level. We find an overall positive effect of pension income on independent living as well as considerable heterogeneity. The positive income effects of the NRPS are concentrated among the elderly with adult children living nearby, of higher socio-economic status, and with better health at baseline; for other groups, the effects are insignificant. We also find that more generous programs exhibit larger effects. Our results highlight that living arrangement is multidimensional in rural China.     

生命价值视角下农村留守老人的供养制度

农村留守老人的供养制度主要包括以种植或养殖为基础的自我供养、以晚辈支撑为基础的后代供养和以福利支持为基础的社会供养.对中国留守老人而言,“居家养老”仍会是未来一段时间符合乡村现实的养老方式.目前,“居家养老”所依靠的自我供养和后代供养逐渐呈现衰微的趋势,社会供养也十分有限.文章通过对留守老人社会角色的重新认知,可以发现他们并非“废弃的生命”,而是乡村重要的根基.立基于留守老人生命价值的供养制度应当包含:基于“分享”理念的福利制度,使留守老人从社会财富中分得应有份额;基于“大健康”理念的医疗制度,对留守老人的健康进行防微杜渐式关照;以“自下而上”理念为基础的文化制度,使留守老人真正获得精神喜乐.     

民族、婚姻、伙有共耕与上帝:基督教嵌入藏区傈僳族社会之阐释——以滇西北德钦县霞若乡为例

基于对云南西北部一个傈僳族乡村全体傈僳族自20世纪90年代以来改信基督教的过程进行考察,指出傈僳族信仰基督教是身处碎片化、原子化社会结构中的族群面对周边民族的歧视与物质资料和人口再生产的重重压力下作出的无奈选择,提出“婚姻一家庭一土地一民族”是基督教在傈僳族社会传播的网络,这一模式可以解释为什么基督教在傈僳族社会传播呈现出民族性特征,区别于基督教在汉族乡村社会传播呈现出的宗族性特征.     

Parameterized algorithms for min–max 2-cluster editing

For a given graph and an integer t, the Min–Max 2-Clustering problem asks if there exists a modification of a given graph into two maximal disjoint cliques by inserting or deleting edges such that the number of the editing edges incident to each vertex is at most t. It has been shown that the problem can be solved in polynomial time for \(t<n/4\), where n is the number of vertices. In this paper, we design parameterized algorithms for different ranges of t. Let \(k=t-n/4\). We show that the problem is polynomial-time solvable when roughly \(k<\sqrt{n/32}\). When \(k\in o(n)\), we design a randomized and a deterministic algorithm with sub-exponential time parameterized complexity, i.e., the problem is in SUBEPT. We also show that the problem can be solved in \(O({2}^{n/r}\cdot n^2)\) time for \(k<n/12\) and in \(O(n^2\cdot 2^{3n/4+k})\) time for \(n/12\le k< n/4\), where \(r=2+\lfloor (n/4-3k-2)/(2k+1) \rfloor \ge 2\).     

A narrative inquiry into the identity formation of Chinese doctoral students in relation to study abroad

The present study explores a topic which has been under-studied to date, namely the identity formation of Chinese PhD students in relation to study abroad. Underpinned by Giddens’ ‘reflexive project of the self’, which privileges agency and reflexivity, and using a narrative inquiry approach, it presents four students ‘stories’ collected through semi-structured interviews and focus group discussions. In building a picture of the ways in which students’ self-identity is shaped by and shapes their experience of study abroad, the stories illustrate individual agency, motivation, self-determination and reflexivity. In doing so, they challenge the essentialised view of Chinese students as a homogeneous and sometimes problematic group and point to implications for action by the host institutions.     

犯罪圈的扩张及其合理限制——以我国刑事立法的变迁为视角

犯罪圈的扩张是我国刑事立法的主导方向,现代化的发展、权利的保护是犯罪圈在特定时期不断扩大的主要原因。立法上的犯罪化的内在根据,在于行为具有应受刑罚处罚程度的社会危害性。犯罪圈的扩张应当受到合理限制：遵循刑法的谦抑性原则,考虑新增罪名与其他罪名的关系,考虑国民的感受与认同并理性对待民意,在注重入罪的同时,也应做到及时地出罪。     

浅析高校女教工在山西转型跨越发展中的使命

在山西＂十二五＂转型跨越发展的过程中,高等教育在推动区域科技进步与产业转化、为区域经济发展提供智力与技术支持、为区域经济发展奠定软环境基础等方面都具有重要作用。而随着数量、素质的不断提高、结构比例的持续优化,作为具有合素质较好、知识层次较高、创新能力较强、社会影响较大等特点的高校女教工群体更应该在人才培养、科学研究、社会服务等诸多方面,充分发挥其作用,为推动山西转型跨越发展做出更大的贡献。     

民族概念三题

本文通过对汉语民族概念的模糊性,斯大林所论述的民族概念的外延与内涵,以及民族概念的政治属性等三个问题展开讨论,认为:第一,汉语民族概念实际表述着中华民族和构成中华民族的56个民族两个层次人们共同体的含义;第二,斯大林所定义的民族(нация)概念指的是汉语民族概念的第一层次,即中华民族这一层次的人们共同体;第三,不论是中华民族层次还是构成中华民族的56个民族层次的人们共同体都具有政治性,但是,两者的政治属性具有层次性,即前者的政治性与国家相关,而后者的政治性则与地方自治相联系。
