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.

政府监管与企业加入第三方国际环境审计的模糊博弈分析

针对政府环境监管与企业实施环境行为博弈分析中无法对双方的损益情况做出判断的问题,文章结合三角模糊数构建了政府监管和企业加入第三方国际环境审计的博弈模型,分别指出了纯策略纳什均衡和混合策略均衡情况需要满足的条件,讨论了政府与污染环境企业博弈策略的影响因素及作用机制,为政府监管与企业加入第三方国际环境审计顺利实施提供了相关建议。然后通过三角结构元方法对算例进行求解,验证了结论的正确性和可行性,引入三角模糊概念更加符合实际应用情况,拓展了第三方国际环境审计的应用背景。研究结果表明,政府对消费者消费的引导和对污染企业的惩罚对企业是否决定加入第三方国际环境审计起着举足轻重的作用。     

无锡市某区残疾人辅助器具需求分析

目的:探索不同状况下残疾人辅助器具的需求差异,找出原因,为制定辅助器具服务政策和合理配发辅助器具提供客观依据?方法:基于全国残疾人基本服务状况和需求专项调查,通过横断面调查获取无锡市某区9个街道(镇)残疾人及疑似残疾儿童的调查问卷6 188份?调查内容包含基本信息?残疾类别?残疾等级?教育文化程度等?采用SPSS22.0 统计软件进行Logistic回归分析?结果:残疾人的辅助器具需求受到残疾种类(P < 0.001)?残疾等级(P < 0.001)?年龄(P = 0.024)?就业情况(P = 0.002)和前一年是否获得辅具(P < 0.001)的影响,性别(P = 0.805)?婚姻状况(P = 0.459)?社保状况(P = 0.195)与教育文化状况(P =0.451)无影响作用?结论:听力?视力?肢体?多重残疾会导致辅助器具需求升高,重度残疾?儿童和老人?未就业和前一年获得辅具都能预示人群较高的辅具需求?

On the robustness of the generalized fused lasso to prior specifications

Using networks as prior knowledge to guide model selection is a way to reach structured sparsity. In particular, the fused lasso that was originally designed to penalize differences of coefficients corresponding to successive features has been generalized to handle features whose effects are structured according to a given network. As any prior information, the network provided in the penalty may contain misleading edges that connect coefficients whose difference is not zero, and the extent to which the performance of the method depend on the suitability of the graph has never been clearly assessed. In this work we investigate the theoretical and empirical properties of the adaptive generalized fused lasso in the context of generalized linear models. In the fixed \(p\) setting, we show that, asymptotically, adding misleading edges in the graph does not prevent the adaptive generalized fused lasso from enjoying asymptotic oracle properties, while forgetting suitable edges can be more problematic. These theoretical results are complemented by an extensive simulation study that assesses the robustness of the adaptive generalized fused lasso against misspecification of the network as well as its applicability when theoretical coefficients are not exactly equal. Our contribution is also to evaluate the applicability of the generalized fused lasso for the joint modeling of multiple sparse regression functions. Illustrations are provided on two real data examples.     

新时代社会主义意识形态的功能提升研究

意识形态功能是意识形态基础研究的核心问题,从意识形态功能提升视角切入是推进我国社会主义意识形态建设的新视阈。在意识形态功能的研究中,抛开时代背景和具体实践谈功能,极易出现意识形态功能研究的“虚化”,形成对意识形态功能的空洞认识。在新时代的历史方位下,结合习近平新时代中国特色社会主义思想论证社会主义意识形态在政治、经济、文化、社会和外交领域的相关功能,以期在市场化、“微时代”、全球化的大环境下通过引领社会主义市场经济改革方向、净化网络空间以及争夺国际话语权等途径,真正实现社会主义意识形态功能的全面提升。     

The West,Russia, and China in Central Asia: What Kind of Game Is Being Played in the Region?

The article discusses the nature of the tangled interaction between the ex-Soviet Central Asian republics and the outside great powers – Russia, the United States and China. Although the so-called Great Game model is often used to explain the geopolitical rivalry in the region, the current pattern of relations between various international actors is much more complex than a traditional tug-of-war between the old colonial empires. While Russia's strategic role in Central Asia appears to be on the rise, the capacity of the West to influence political developments in the region has diminished. However, the overall situation in Central Asia remains volatile and its geopolitical landscape is far from being settled.
