河北省R＆D活动与高新技术产业的发展

高新技术产业作为以技术带动发展的重点产业,研究与开发的投入情况直接影响到它的发展速度。由河北省研发投入规模、投入主体、支出领域、企业性质、研发人员情况、科技产出情况六方面的考察可知,河北省研发活动存在投入不足、人力资源缺乏问题,应提高研发效率,引进科技人才、加强对引进技术的消化与吸收、拓宽高新技术产业融次渠道。     

The heterogeneous relationship between board social ties and corporate environmental responsibility in an emerging economy

Firms in emerging economies are faced with multiple, incompatible institutional forces in their environmental activities. Which of these forces will be dominant and instantiated within an organization is partly determined by the social relationships that a firm maintains with external actors. This paper investigates the relationship between board social ties and the level of environmental responsibility undertaken by firms in China, an emerging economy, by categorizing board social ties into three types in terms of the three isomorphic forces in the institutional field (coercive, normative and mimetic). Drawing on institutional and agency theories, using a sample of listed firms in environmentally sensitive industries, and a generalized least squares regression method, the results provide empirical evidence that ties that are linked to coercive and normative forces (i.e., political organizations and universities) are related to a higher level of environmental responsibility; however, those that are linked to mimetic forces (i.e., industrial peers) have a negative association with environmental responsibility, which is mitigated by CEO power. These findings suggest that the heterogeneous effects of board social ties on environmental responsibilities experienced by firms in a context of environmentalism are at an early stage.     

Experiencing meaningfulness climate in teams: How spiritual leadership enhances team effectiveness when facing uncertain tasks

This study integrates social information processing theory with leadership and climate literature, and aims to produce novel theoretical insights into whether and how spiritual leadership and task uncertainty foster conditions to enhance meaningfulness climate and subsequent team effectiveness in China. Team effectiveness was operationalized as team performance and team organizational citizenship behavior (OCB). Based on data collected at three time points over 12 months from multiple sources of 123 teams in China, we found that spiritual leadership was positively related to team performance and team OCB through meaningfulness climate. Further, the relationship between spiritual leadership and meaningfulness climate was stronger for teams with high task uncertainty than teams with low task uncertainty.

自然策化安全系统构架危岩体的预警

仅仅立足于预警,是一个被动措施,换句话说仅仅等待滑坡的发生,而人类的期望是最好不要发生这类事件。为此,人类必须立足于主动的地位,积极采取必要而正确的措施避免滑坡的发生,这类措施在多数场合主要是科学地布置好地表排水系统,合理布局林、地、田,而不是挡土墙等大规模工程。
