东北老工业基地产业集群入群行为博弈分析

通过引入企业收入风险系数、风险折扣的期望收益、合作产出效果系数、贴现系数、合作正反馈因子等,运用博弈论构建了核心企业与集群伙伴间两企业合作博弈模型,对东北老工业基地产业集群的入群行为进行了研究。以此模型为基础,分析了产业集群构建的各种约束条件,并提出了东北老工业基地产业集群形成与成长的策略。

基于主成分投影法的东北老工业基地产业集群伙伴选择研究

东北老工业基地是以国有大型企业为核心,众多中小企业和相关机构组成的地理集聚体。这种特点决定了其产业集群是以核心企业为主体,通过集群合作伙伴的选择来组建产业集群。集群伙伴合作能力的评价是组建集群的关键。由于集群合作伙伴选择的评价是多目标、多属性评价,而且评价指标间的信息相互重叠,因此提出了基于主成分投影法的集群伙伴合作能力评价选择,分析了集群合作伙伴选择原则,构建了评价指标体系,建立了基于主成分投影法的集群伙伴合作能力评价模型,并结合算例加以应用。

Effects of Counselling on In-School Adolescents＇ about HIVIAIDS in Malaysia

The study examined the effects of counselling on in-school adolescents about HIV/AIDS in Malaysia. A total of 100 male and female students were randomly chosen from three residential commercial areas located in Kuala Lumpur in Malaysia. A questionnaire on HIV/AIDS symptoms was administered. The findings of the study indicated that two thirds of the interviewed adolescents have high desires to live longer on the earth. Also, adolescents do not associate high death rates of youths with HIV/AIDS symptoms. This report has implications for HIV/AIDS counselling in the Malaysian school system. This is supported by the fact that with the success of retrovirus therapy, many of the infected now live healthier lives and are pursuing a wider range of activities. Many HIV/AIDS infected people today can participate in undergoing their daily life activities, with a significant chance of living longer on the earth. The authors conclude that collaborative partnership between HIV/AIDS services and HIV counselling as part of the integrated system will provide early intervention services to boast relief of anxiety for the young people in Malaysia who already live with HIV/AIDS.

集体学习与个体学习

学生的在校学习有两个突出特点:一是在教师指导下学习,二是在伙伴集体中学习。因此,教会学生学习,必须首先教会他们适应和善于在集体情境中学习,然后才是自学能力的培养与习得。集体学习对个体学习具有许多有利因素和积极影响。本文就此问题试作探讨。 一。
