Political Commitment,Policy Ambiguity,and Corporate Environmental Practices

A lack of clear political commitment together with confusing rules and enforcement often characterize the institutional context of policy implementation and regulatory compliance in developing countries. By connecting such contextual features to existing models of policy implementation and regulatory compliance, we examine how regulatory factors are related to basic and proactive corporate environmental management practices in the Pearl River Delta region in China. Drawing on data derived from both a survey and in‐depth interviews, we show that a perception of clear political commitment to environmental protection across multiple government levels and units is positively associated with business efforts in basic environmental practices, regardless of the specific enforcement intensity. Nevertheless, a perception of clear political commitment is not related to proactive environmental practices. Conversely, a perception of policy ambiguity, in the form of confusing regulatory standards and enforcement, is negatively associated with corporate efforts in both basic and proactive environmental practices; yet, intensive inspections mitigate these negative associations with policy ambiguity.     

PLANTING TREES ON THE ROOF OF THE WORLD

正In China,legend says that animals choose different trees to inhabit.In Nagqu,situated on the northern area of the Tibet Autonomous Region,trees are nowhere to be seen,and birds often share holes underground with mice and rabbits.Nagqu means"black river"in Tibetan.The place is situated     

国家权力、企业家精神与企业经营——以通用机器有限公司(1946~1949)为例

通用机器有限公司是国民政府资源委员会在抗战胜利后创办于上海的国有机械制造企业。资源委员会委派私营企业家马雄冠作为公司负责人,并肯定了马雄冠的"纯商业化"经营路线,使公司能边基建边投产运营,缓解了资金压力,在恶劣的局势下取得较好的成绩。尽管马雄冠为公司注入了企业家精神,但公司的销路问题有赖于资源委员会的重工业建设,其技术引进也由资源委员会负担了大笔先期资金,因此,该公司的成功是良好政企关系的产物。

Quantifying Animal Trajectories Using Spatial Aggregation and Sequence Analysis: A Case Study of Differentiating Trajectories of Multiple Species

The increasing availability of telemetry data with high spatial and temporal resolution promises to greatly advance scientific understandings of the movement patterns of individual organisms across space and time. The amount of data provided by such methods, however, can be challenging to analyze and interpret. In this study, we present a new approach for analyzing animal movements that aggregates telemetry locations into spatial clusters and extracts the information from sequences formed by individuals passing through these spatial clusters. We applied this integrated approach of spatial aggregation and sequence analysis to quantify and compare trajectories of cattle (Bos taurus), mule deer (Odocoileus hemionus), and elk (Cervus elaphus) tracked by automated telemetry at the Starkey Experimental Forest and Range in northeastern Oregon, USA. Our approach effectively differentiated movement patterns of the three species. It provides a useful mean of quantifying movement patterns of species in a landscape.     

全球—地方视角下西安市软件产业集群的创新效应研究

全球—地方关系为产业创新研究提供了新的视角。本文基于全球（通道）—本地（蜂鸣）关系视角构建了软件产业集群创新效应研究的理论框架。以西安市软件产业集群为例,采用Stata13定量分析不同尺度创新合作的创新效应及其影响因素。研究发现,本地和国际创新合作均对集群创新具有积极的影响,且后者比前者的创新效应更强,说明搭建外部通道对集群创新的必要性;本地与国际创新合作交互对不同规模的软件企业产生的创新效应不同,对小型软件企业存在减法效应,对中型软件企业存在加法效应,对大型软件企业具有乘法效应。建立领先软件企业带动的开放创新系统,是西安市软件产业集群提升创新效应的有效路径。

光绪癸未年宁波金融汇票

2003年3月,笔者在宁波范宅古玩市场收集到一张宁波当地的光绪癸未年金融汇票（如图）及其他借票、除票等若干张。这批票据均是在镇海被发现整理出来的,同时发现的还有清代的田契、税单等,《宁波晚报》2002年11月8日“清代税票现身范宅”曾作报道。     

晚清圣母圣心会中蒙古教区传教述论

本文认为,晚清时期,圣母圣心会在中蒙古教区获得了持续、稳定的发展。教会的成功既在于其传教方法得当,也在于教会拥有较多的社会资源。怎样评价教会的传教活动,并不是一个容易的话题。     

青州造像所见佛塔之样式、渊源与功能初探

青州佛塔具有相当的自身特色,即采用覆钵顶下高大的方形塔身,并且塔身四面均开龛置像。再考察与青州同时或稍早的云冈、龙门、响堂等处的佛塔,发现青州佛塔的来源当是北魏以来中原佛塔的典型样式,它的布局形式则明显受邺城地区佛像的影响。综合考虑北朝晚期的历史背景,青州造像上大量佛塔的出现,估计与法华经的信仰、末法的信仰有着一定的联系。而这时青州佛塔的功能则主要演变成一种装饰纹样。
