霍尔顿:美国三喻文化的一面折射镜

作为美国20世纪50～60年代青年一代的代言人,<麦田里的守望者>中的主人公霍尔顿折射了第二次世界大战后美国三喻文化的特征:后喻文化的失效、并喻文化的失衡以及前喻文化的召唤.     

Contextualizing the Governance of Community Co-operatives: Evidence from Austria and Germany

The article inquires into the role of the institutional context in explaining the governance of community co-operatives. These organizations do not solely focus on a member’s advantage but act on behalf of some collective identity. To enhance our understanding of the nature of co-operative governance on the neighborhood level, we draw on theoretical concepts that are context-sensitive, helping us to catch the institutional conditions in a specific place which are enabling individuals and groups to act and organize collectively. Thus, we enrich the abstract concept of governance put forward by New Institutional Economics. Based on a systematic analysis of case studies, the paper shows that the governance of community co-operatives is based on place-bound values. However, the encounter of divergent imaginations of the neighborhood results in different co-operative practices: e.g., either a government-directed practice to “discipline” the community or a community-initiated practice of self-organization.     

网络技术下统计的变革和统计教育面临的任务

网络经济的发展使现行的统计信息生产方式和统计制度发生深刻变革,使统计人才的知识结构发生重大变化,从而对统计教育的着力点和培养目标、培养方式提出了新的要求。如何培养大量优秀的复合型统计人才,极大地提高统计人员的素质,是统计教育面临的艰巨任务。     

黄山绞股兰对赡蜍体心脏的作用

蟾蜍离体心脏灌流实验表明:黄山采集的绞股兰、绞股兰茶剂、生晒参在低浓度时均能增加蟾蜍离体心脏的收缩振幅。其作用为:黄山绞股兰>生晒参>绞股兰茶剂,其后作用也以黄山绞股兰最强。高浓度时均能抑制心脏的搏动,使心脏停止于收缩状态,更换任氏液后心脏的搏动可以恢复。三种药物均对心率无明显的影响。

高等学校图书馆导读与信息素养教育

简释了高等学校图书馆导读、信息素养和信息素养教育的内涵,阐述了高等学校图书馆导读与信息素养教育的关系,导读对读者信息意识具有的激发作用,对读者信息能力提高具有促进作用,对读者信息道德教育具有服务保障作用.因此,创新导读工作,人文精神与科学精神的融合是推动导读的动力,文献检索课的改革是深化导读的基础,图书馆馆员信息素养的水平是提高导读质量的关键.     

Nonlinear mixed‐effect models with nonignorably missing covariates

Nonlinear mixed‐effect models are often used in the analysis of longitudinal data. However, it sometimes happens that missing values for some of the model covariates are not purely random. Motivated by an application to HTV viral dynamics, where this situation occurs, the author considers likelihood inference for this type of problem. His approach involves a Monte Carlo EM algorithm, along with a Gibbs sampler and rejection/importance sampling methods. A concrete application is provided.     

有界风险模型中Gerber-Shiu函数的若干结果

研究了有界风险模型中的Gerber-Shiu函数,得到了当索赔到达Erlang(2)过程时Gerber-Shiu函数满足的微积分方程,并进行求解.进而研究了延迟更新有界风险模型中,对首次索赔时刻的分布加入一个新的参数时Gerber-Shiu函数的变化,并得到了一个数学上易处理的Gerber-Shiu函数的公式.
