关于族群关系、民族关系与社会关系的关系

"族群"与"民族"概念上存在着交叉关联.族群关系、民族关系都是一种社会关系,但社会关系不一定都构成民族关系,民族关系有时也不一定能够准确地表述特殊的社会关系,族群关系却可以化解民族关系表述的"潜在危机".族群关系、民族关系与社会关系的关系具有多向性、非对称性和动态性的特点.

论中国回族及其文化

回族是在中国历史上发展形成的一个民族群体,并对中国社会发生重大的影响。把民族与宗教信仰紧密联系在一起,是中国回族最突出的特点,也是最重要的特点。中国回族实际上是直接受到两种思想和两种文化的影响和教育。中国回族先民在融会贯通伊斯兰思想和儒家思想方面,有许多创新和独到之处,积累了丰富的经验,提出了许多切实可行的理论和观点,取得了很好的效果,也树立了不同思想和文化之间交流和对话的典范。今天,在新形势下,我们更应该发扬这种精神,积极创造条件,加强民族团结,促进社会和谐。

Identifying Latent Structures in Panel Data

This paper provides a novel mechanism for identifying and estimating latent group structures in panel data using penalized techniques. We consider both linear and nonlinear models where the regression coefficients are heterogeneous across groups but homogeneous within a group and the group membership is unknown. Two approaches are considered—penalized profile likelihood (PPL) estimation for the general nonlinear models without endogenous regressors, and penalized GMM (PGMM) estimation for linear models with endogeneity. In both cases, we develop a new variant of Lasso called classifier‐Lasso (C‐Lasso) that serves to shrink individual coefficients to the unknown group‐specific coefficients. C‐Lasso achieves simultaneous classification and consistent estimation in a single step and the classification exhibits the desirable property of uniform consistency. For PPL estimation, C‐Lasso also achieves the oracle property so that group‐specific parameter estimators are asymptotically equivalent to infeasible estimators that use individual group identity information. For PGMM estimation, the oracle property of C‐Lasso is preserved in some special cases. Simulations demonstrate good finite‐sample performance of the approach in both classification and estimation. Empirical applications to both linear and nonlinear models are presented.     

Repurposing Materials and Waste through Online Exchanges: Overcoming the Last Hurdle

Online material and waste exchanges (OMWEs) provide online channels to repurpose by‐products, unused materials and waste from industrial and commercial facilities. Unfortunately, OMWE's also have challenges. First, sellers may have access to other disposal options and, as a result, may not fully commit to the exchange. Second, buyers can face high uncertainty about the product exchanged and the transaction being undertaken. Overcoming these challenges is the “last hurdle” to making OMWEs successful. This study investigates the factors that reduce the buyers' uncertainty and increase the sellers' commitment to the OMWE. We analyze novel transaction‐level data from an online exchange (MNExchange.org) combined with other archival public records on county‐level repurposing and disposal statistics. First, we find that regional repurposing policies and alternatives have a complementary effect on sellers' commitment toward OMWEs, resulting in increased OMWE exchanges. However, regional disposal policies and alternatives have a substitution effect on sellers' commitment, resulting in reduced exchange success. Further, greater product and transaction information reduce the buyer's uncertainty and increase exchange success. Finally, the analysis shows that users' (buyers and sellers) heavily rely on their prior experience with OMWEs. Specifically, higher familiarity between the buyer–seller pair and familiarity with the OMWE system leads to higher likelihood of exchange success. This study lays the foundation for understanding OMWEs and has important implications for developing policies and operations to increase online transactions of by‐products, materials and wastes.     

农产品网购意愿影响因素及作用机理研究——基于参照效应视角的分析

以整合型科技接受和使用模型(UTAUT)和价值接受模型(VAM)为基础,通过构建参照群体、参考价格、积极在线评论与感知价值、感知风险以及购买意愿之间的关系模型,从参照效应视角实证分析了农产品网购意愿的影响因素及作用机理,并探讨了消费者农产品质量与安全意识在参照效应影响网购意愿中的调节作用.结果表明:参照效应对农产品网购意愿有显著影响;感知价值和感知风险在参照效应影响网购意愿中均发挥了中介作用,但感知价值的中介作用显著大于感知风险;消费者农产品质量与安全意识在参照效应影响网购意愿中部分地发挥了调节效应.其中,对参照群体和积极在线评论的调节效应显著,即网购过程中,消费者越是重视农产品质量与安全,参照群体的意见和积极在线评论对其网购意愿的影响就会越凸显.     

农村邻避型环境群体性事件引入行政诉讼禁令判决的分析

行政诉讼禁令判决,是指根据行政相对人的申请,人民法院作出的,要求行政机关不得实施某项行政行为的判决,是法院为制止违法行政行为可能造成的潜在性风险的一种预防性的判决方式。我国农村邻避型环境群体性事件中,现有权利救济机制存在环境司法治理模式边缘化、政府环境风险监管责任乏力以及事后救济难以恢复生态环境等缺陷,因此,亟有必要在农村邻避型环境群体性事件中引入行政诉讼禁令判决并进行相应的制度构建,从而达到防范环境风险、树立司法权威和保障农民环境权益的目的。
