General convex order on risk aggregation

Using a general notion of convex order, we derive general lower bounds for risk measures of aggregated positions under dependence uncertainty, and this in arbitrary dimensions and for heterogeneous models. We also prove sharpness of the bounds obtained when each marginal distribution has a decreasing density. The main result answers a long-standing open question and yields an insight in optimal dependence structures. A numerical algorithm provides bounds for quantities of interest in risk management. Furthermore, our numerical results suggest that the bounds obtained in this paper are generally sharp for a broader class of models.

集团化办学：一种职业教育集群价值链增值模式的选择

企业集群理论是从价值增值环节研究经济组织和资源配置的管理学理论,企业集群的互利机理与共生机制对指导职业教育集团的发展有着重要的意义。文章结合我国职业教育和职教集团的现状,提出集团化办学是一种职业教育集群升级模式。职教集群升级本质上是集群治理效率的提升。我国职教集团化办学大体处于短距离市场价值链层级,要实现价值链的高移与升级,必须加快从短距离市场价值链到准等级型价值链的演进和从准等级型价值链到网络型价值链的提升。而要实现这种升级,必须基于深度产学合作和资源整合实现职业集团角色转型和准确定位,以实现职业教育与区域经济的良性互动与对接。

The Effectiveness of a Buzz Marketing Approach Compared to Traditional Advertising: An Exploration

Marketers are now willing to go anyplace they can find a captive audience to espouse the virtues of their products. The success of the “buzz” marketing approach is linked to the consumer being lured into doing the advertising by spreading the message to others. This study compares students’ responses to a traditional advertising and a buzz approach. Using a factor analysis to identify variables, the results show that subjects perceive a buzz approach to be more influential than a traditional advertising. However, they do not perceive a buzz approach to be authentic. This finding is consistent with practitioners’ argument that, although a buzz approach may be effective in the short-term, once consumers recognize its selling intent, the program may have a “boomerang effect.”     

Perceptions of facilitators of a keypad‐based group support system

Organizations are using Group Support Systems (GSSs) to improve the quality of group meetings. Keypad‐based GSSs are a widely used form of this technology, yet there has been little research on their use and effects. This paper reports the findings of a survey of facilitators of a particular keypad GSS. Facilitators indicate that keypad technology improves the quality of meetings for a variety of tasks in a range of group settings and cultures. The findings are in general agreement with field studies of workstation‐based systems.
