他者话语的反思：欧美学界关于中国海外藏人研究评析

“西藏问题”,尤其是中国海外藏人问题,是我国党和政府始终关切的重要问题。自1959年西藏叛乱以后,中国海外藏人问题在一些西方国家备受关注,也成为欧美学者们竞相展开调查研究的重要领域,关于这一主题的研究涉及了国际关系、人口迁移、国际援助、难民政策、身份政治、文化传播等诸多领域。本文将在对大量欧美学者的相关专著与论文进行整体把握的基础上,厘清欧美学界海外藏人研究的基本特点,对欧美学界的相关研究状况进行分析,并重点分析了欧美学者对中国海外藏人社区的实地研究,指出许多研究过分服务于政治目的,或研究中情绪色彩过重,或关注点过于集中于中国海外藏人的处境状况。因此,国内的相关研究应发挥本土优势,关注中国海外藏人生活境遇,将海外藏人研究与国内藏族研究相结合,构建起更加完整的藏族研究体系。     

论劳动争议案件审理程序衔接中若干实务问题

我国劳动争议处理体制实行诉讼前的“仲裁前置”程序,现行法律对劳动仲裁与劳动诉讼衔接中的许多问题规定得不甚明确,导致实务中存在许多模糊区域,进而使劳动者的合法权益维护受到了一定的阻碍。因此,研究劳动仲裁与劳动诉讼衔接中的相关问题,有重要的现实意义。劳动仲裁与劳动     

线上线下融合模式下考虑战略顾客行为的供应链协调研究

在移动电商高速发展和移动支付日益便捷的时代,线上线下融合商务模式正日益成为传统零售、电子商务甚至快递物流企业转型升级的重要方向,影响着供应链运营管理及其优化决策。线上线下融合模式下的战略顾客行为不同于传统模式,其对于供应链运营管理及其优化决策的影响也不同于传统模式。基于O2O运作模式特征,运用战略顾客行为理论、供应链优化与协调理论,本文分别构建了"线上下单+线下体验+线下支付+自行提货"O2O模式1、"线上浏览+线下体验+线上购买+线下配送"O2O模式2、纯线下模式和纯线上模式下考虑战略顾客行为的供应链集中决策模型和契约协调模型,并进行了相应的数值分析,在此基础上,提出了相应的管理启示。研究结果表明：（1）无论是"线上下单+线下体验+线下支付+自行提货"O2O模式1还是"线上浏览+线下体验+线上购买+线下配送"O2O模式2,收益分享契约机制可以有效地实现战略顾客行为下的供应链协调。（2）对比两种O2O模式和两种非O2O模式,O2O模式1和O2O模式2能给供应链及其成员带来更多的利润,而纯线上模式和纯线下模式能给战略顾客带来更高的效用。（3）O2O模式下,制定较高的自提补贴和较低的折扣价格,有利于提高供应链及其成员的运营绩效。（4）O2O模式下,增强产品及其相关服务的实际体验效用,有利于提高供应链整体及其成员的运营绩效,有利于提高战略顾客的净效用。     

Relation between the skew-rank of an oriented graph and the independence number of its underlying graph

An oriented graph \(G^\sigma \) is a digraph without loops or multiple arcs whose underlying graph is G. Let \(S\left( G^\sigma \right) \) be the skew-adjacency matrix of \(G^\sigma \) and \(\alpha (G)\) be the independence number of G. The rank of \(S(G^\sigma )\) is called the skew-rank of \(G^\sigma \), denoted by \(sr(G^\sigma )\). Wong et al. (Eur J Comb 54:76–86, 2016) studied the relationship between the skew-rank of an oriented graph and the rank of its underlying graph. In this paper, the correlation involving the skew-rank, the independence number, and some other parameters are considered. First we show that \(sr(G^\sigma )+2\alpha (G)\geqslant 2|V_G|-2d(G)\), where \(|V_G|\) is the order of G and d(G) is the dimension of cycle space of G. We also obtain sharp lower bounds for \(sr(G^\sigma )+\alpha (G),\, sr(G^\sigma )-\alpha (G)\), \(sr(G^\sigma )/\alpha (G)\) and characterize all corresponding extremal graphs.     

异质性技术视角下中国高技术制造业创新效率研究

目前,学术界对选取何种风险调整贴现率期限结构还存在争议,导致对同类投资项目得 出不同的管理指引意见． 针对这一争议,本文通过划分资本产出方式, 寻找影响贴现率结构的 主要因素． 研究表明,不确定的宏观经济产出和项目非系统风险共同影响风险溢价系数, 同时 风险溢价系数决定贴现率期限结构． 其中,当风险溢价系数大于某确定阈值, 贴现率随时间递 增; 其余情况表现为递减．     

自媒体时代“网络话语权”的二元结构解析与规制

自媒体的出现修正了媒体资源分布失衡的弊端,促使个体身份发生角色转变,进而使话语权的行使形成了“话语权利”与“话语权力”两个维度.前者是言论自由在网络空间的体现,后者是个人言论衍生为媒体式表达后形成的超个体权力.“话语权利”的行使应当受国家对言论自由所设的界限限制,“话语权力”的赋予则使自媒体成为国家新闻管理体制下的“准媒体”,其作为互联网新闻信息服务提供者,应当受到约束与规制.     

经典剧作的对外传播与中国国家形象建构

经典剧作是我国优秀传统文化的代表,是中国人民智慧的结晶,也是中华民族优良品德的集中体现。做好经典剧作的对外传播,有利于将客观、真实的中国介绍给世界,消除个别国家对我国国家形象的误解,对于我国的社会主义现代化进程和在国际社会树立良好的大国形象,具有积极的推动作用。     

Divorce Chinese Style

This study investigated divorce during China's social and economic transformation period from 1970 to 2012. Specifically, the study examined the trend development of divorce and demonstrated how marriage formation type and individual socioeconomic characteristics were associated with the likelihood of divorce across time. Event‐history analysis was applied to longitudinal data from the China Family Panel Studies (2010–2012 waves). The results showed a threefold increase in divorce from the pre‐1990s to the 1990s. Surprisingly, the trend shifted to a plateau toward the 2000s. When cohabitation was in its rapidly diffusing stage in the 1990s, individuals who cohabited prior to marriage had a substantially higher likelihood of divorce. As cohabitation became increasingly common in the 2000s, its effect on divorce weakened. The role of socioeconomic characteristics in divorce also varied across time. This study enriches the knowledge of family dynamics in contemporary Chinese society.     

Parental divorce, sibship size, family resources, and children’s academic performance

Using data from 19,839 adolescents from the National Education Longitudinal Study, this study investigates whether the effects of parental divorce on adolescents’ academic test performance vary by sibship size. Analyses show that the negative effect of divorce on adolescent performance attenuates as sibship size increases. On the other side of the interaction, the inverse relationship between sibship size and test performance is weaker in disrupted than in two-biological-parent families. Trends of such interactions are evident when sibship size is examined either as a continuous or a categorical measure. Finally, the observed interactions on adolescents’ academic performance are completely explained by variations in parental financial, human, cultural, and social resources. In sum, this study underlines the importance of treating the effect of parental divorce as a variable and calls for more research to identify child and family features that may change the magnitude of such an effect.
