生态环境的恶化与乡村社会控制--以清代徽州的棚民活动为中心

从明后期开始进入徽州地区的外地棚民，利用当地丰富的自然资源，进行各种经济活动。在当时的社会条件制约下，此类经济活动耗费了大量的资源，破坏了徽州农村的生态环境，损害了地方和国家的利益。针对这一问题，清代徽州乡村社会各种民间力量和官方联合展开了一场声势浩大的驱禁棚民运动，取得了预期效果。

Factors that affect accountant's perceptions of alternative work arrangements

Advances in technology have impacted accounting careers with resulting changes in where, when and how accountants perform their job duties. In addition, employee attitudes towards, and need for, better work/life balance has led to more firms offering alternate work arrangements (AWA). Research suggests that AWA programs can lead to many benefits for both employers and employees. Despite the prevalence of these programs there are relatively few accountants working under these arrangements and concerns about work/life balance continue. This study examines factors that shape perceptions of the cost and benefits associated with the adoption and/or support of AWAs across work culture, gender and participation experience. Our results suggest that work environment had a significant effect on perceptions of AWAs. Public accountants perceived greater costs related to career advancement but correspondingly less concern about administrative issues than management accountants. We also found that accountants who have participated (or are currently participating in an AWA), perceived greater benefits and less concern for potential negative consequences to their careers than non-participants. Finally, women perceived greater benefits to result from participation in an AWA and men perceived correspondingly more costs. Regardless, both genders perceived that AWAs were not strictly a women's issue. These findings contribute to our understanding of alternate work arrangements and point to factors that must be addressed to increase the acceptance and success of these programs.

The European high-speed train network: Predicted effects on accessibility patterns

The principal aim of this paper is to evaluate the impact of the future European high-speed train network on accessibility, by reducing time distance between places and modifying their relative location. We compare the current situation with that foreseen for the year 2010, according to the Outline Plan of the European High-Speed Train Network, in order to analyse which areas will most benefit from construction and improvement of the infrastructure. It is hypothesized that the high-speed train will certainly bring the peripheral regions closer to the central ones, but will also increase imbalances between the main cities and their hinterlands. A weighted average distance indicator is applied for this purpose. This measure identifies the spatial distribution of accessibility in the area of study, emphasizing the infrastructure effects, and locates accessibility changes at the European level. A Geographic Information System (GIS) has been used to carry out this study.

专业化管理的家族企业——新加坡的华人企业

通过考察大量口迷历史记录、个人访谈、文献研究及有关新加坡经济、社会的评论，研究了亚洲金融危机（以下简称危机）前后新加坡华人企业变化及其发展的持续性，表明危机前，这些大型企业由家族制管理变为专业化管理；危机后，其变化趋势有两种，一种由于面临着西方企业日益激烈的竞争，在政府密切关注下，同时也因缺乏有能力、有管理家族企业意愿的后代，家族制度已松散；另一种由于没有政府的直接管制，在危机后消极的市场形势下，为谋求生存，任用有能力的家族后代充分发挥优势，维持着传统的家族制。本文分别从市场、制度（包括文化和政府）及一些主要大公司的领导者行为分析，推导一个路径清晰、条脉分明的管理变化模式，同时提出进一步的研究方向——专业化管理家族企业的结构及政府的角色。
