社会资本是农村生态环境保护的基石,它可以打破生态环境保护中的“囚徒困境”,促使人们遵守生态环境保护的相关规则,解决人们在生态环境保护中的利益冲突,以及抵御外来污染转嫁。当前,由于城市化进程的加快以及市场、政府力量等向社区的渗透,我国农村社区中社会资本正面临流失的危险,这是农村生态环境恶化的重要原因。社会资本流失只是一种暂时现象,它可以在现代农村社区中得以重构与再生,这种重构与再生,沿袭的是一种价值理性与工具理性相结合的路径。 相似文献

Materialism has been a topic of interest to consumer researchers for decades. This article explores the effect of materialism on individuals' life satisfaction using a large sample from Malaysia, a country with cultural diversity within a collectivist mainstream culture. The results suggest that the effects of materialism on life satisfaction could be indirect, mediated by stress and moderated by religiosity. The study helps to explain the mechanisms that account for the negative relationship between materialism and life satisfaction reported in previous studies conducted in many countries; it provides a blueprint and directions for further research. 相似文献

This paper investigates the role of intermediaries in the initial public offering (IPO) process. In the U.S. market, investment banks have traditionally been involved in a firm‐commitment or best‐efforts underwriting capacity. However, in the Australian IPO market, investment banks are increasingly being named in association with new issues in diverse roles such as issue managers, sponsoring brokers and corporate advisers. Using a sample of 468 IPOs over the 1996 to mid‐2006 period, we examine the influence of investment banks across these different engagements. In support of the signalling and information production roles of intermediaries, we find that issuers choosing high intermediary involvement are typically older, retain more capital, seek to raise larger amounts of capital and are without independent expert certification. We find mixed support for the certification hypothesis when testing for the effect of intermediary reputation on IPO issuer wealth loss. Further, the impact of intermediary involvement on underpricing is not significantly different for the different levels of intermediary involvement once issue characteristics have been accounted for. This is puzzling since these different roles by definition do not provide the same level of issue quality assurance. 相似文献
