国有企业的特殊性与我国国有企业的布局定位

国有企业特殊性的真实内涵表现为,它有着特殊的所有者和所有者代表、特殊的社会目标、特殊的社会经济功能和特殊的产权组织运作机制。因此,越是在以社会目标为主的产业领域,国有企业就越有存在的价值。尽管国有企业的布局是一种趋向性和开放式的动态布局,但它所传递的信息表明国有企业会在特殊产业领域中以合适的方式继续存在并扮演重要角色。

Young helpline callers and difference: exploring gender, ethnicity and sexuality in helpline access and provision

This article, which has its origin in a feasibility study carried out for three youth telephone helplines, focuses on gender, difference and helpline access by young people. During the research process the writers noted that for the three commissioning helplines, as is the case with the majority of other telephone helplines, approximately two‐thirds of callers are female. A helpline for young Muslims where the gender access ratio was 50/50 stood out as being different in this respect. Until recently, literature on gender and help‐seeking has tended towards making a blanket identification of males as experiencing difficulties in negotiating pathways to help. Although this difficulty of males is evident in relation to both help‐seeking and access to helplines, our study suggests that, at least in relation to helpline usage, when we take culture, ethnicity and sexuality into account, the help‐seeking situation may be more nuanced. This has implications in terms of enabling a cross‐section of young people to access helplines as well as with regard to helpline service development.     

垄断企业捆绑销售的策略效应

捆绑销售作为企业常用的销售策略,既有直接效应也有策略效应,国内学者对捆绑销售的论述仅局限于价格歧视等直接效应,而忽视捆绑销售的策略效应。文章指出了通过捆绑销售来进行价格歧视的局限性以及垄断企业进行捆绑销售的策略效应,并通过一个两阶段模型论述了捆绑销售阻止进入的策略原理:在位企业在一定条件下如何通过捆绑销售来阻止进入。

On pooling data summaries in the absence of interactions “response-by-study”

The standard hypothesis testing procedure in meta-analysis (or multi-center clinical trials) in the absence of treatment-by-center interaction relies on approximating the null distribution of the standard test statistic by a standard normal distribution. For relatively small sample sizes, the standard procedure has been shown by various authors to have poor control of the type I error probability, leading to too many liberal decisions. In this article, two test procedures are proposed, which rely on thet—distribution as the reference distribution. A simulation study indicates that the proposed procedures attain significance levels closer to the nominal level compared with the standard procedure.
