制度创新等现代管理理论与公务员队伍管理

众所周知,理论的力量在于它应对问题的能力,即解释问题的效度。管理面对的是组织,尤其是体现为科层制结构的现代组织的结构、行为和变革,因此,制度分析体现在管理学中的优越性,就是为管理本身提供一个组织分析与管理实施的新的框架,现就此进行简要分析。     

Domestic technology,consumption economies of scale and poverty: evidence from Sri Lanka

While it is well known that new technologies enhance consumer welfare, the manner in which these technologies impact the ability to realize economies of scale in consumption is not well understood. We use Sri Lankan household data to examine how the adoption of new technologies by households positively impacts their ability to achieve household economies of scale. This suggests that new technologies not only deliver a greater variety of consumption goods to consumers, but they may also play an important role in enabling large households to escape poverty by lowering the per-capita costs of maintaining a given standard of living. Given the importance of consumption economies of scale in the measurement of poverty, this study provides some insights on the extent to which the number of poor households changes when food consumption scale economies due to technology adoption in the domestic sphere are incorporated.     

The effects of corporate environmental disclosure on environmental innovation from stakeholder perspectives

Based on legitimacy theory and resource dependence theory, using 111 listed companies among China’s typically high pollution-emitting listed corporations, research into the effects of environmental disclosure on environmental innovation is undertaken. From the perspective of stakeholders, we analyse the moderating effects of different proportions of institutional investor holdings and types of enterprises on the relationship between environmental disclosure and environmental innovation. The results indicate that corporate environmental disclosure has a positive role in promoting environmental innovation; the proportion of institutional investor holdings has a positive moderating effect between environmental disclosure and environmental innovation. However, there is no significant difference between state-owned enterprises and private enterprises in terms of the effect of the environmental disclosure on environmental innovation, which possibly arises because both types of enterprises make full use of their own advantages to instigate environmental innovation through environmental disclosure. The conclusions may help enterprise decision-makers implementing environmental innovation and government policy makers formulating scientific policies to promote the clean production in enterprises.     

放射性检测仪器原理及应用

由于放射性危害巨大,且一般情况下必须借助专门仪器方可感知,因此检验检疫人员必须对放射性检测仪器有所了解。本文对放射性检测仪器的主要探测器种类及其原理进行了说明,详细介绍了口岸和实验室常用的各种放射性仪器,并对其应用进行了分析,提出了指导性的应用意见。     

口岸放射性检测仪器的使用

由于放射性物质的特殊性,使得放射性检测仪器成为放射性检验工作的基础。本文对放射性仪器的种类、应用进行了讨论,提出了全面布置、正确设置、规范使用、有效维护的使用原则。并对两种口岸常用放射性仪器编写了使用规范,供日常检验参考。     

An Initial Investigation of Integrating Innovation Diffusion Models for Drawing First‐time Visitors

Prior studies in the existing tourism literature have frequently emphasized the relatively expensive costs for drawing first‐time visitors. These studies, however, have largely failed to explain how to draw first‐time visitors to a destination. In other words, little was known regarding what destinations should do to attract first‐time visitors in an effective way. To provide more insights, this research investigated the impact of three diffusion models on attracting first‐time visitors. These models included an external influence model for impact of mass media, an internal influence model for impact of interpersonal communications, and a mixed model for impacts of both mass media and interpersonal communications. Assessing the model impact in a macroapproach for first‐time visitors to Hong Kong, empirical findings indicated that the mixed influence model provided the highest explanatory quality, with word‐of‐mouth being a dominant factor.     

基于红外通信的数据采集系统

随着红外技术的发展,红外通信已经成为越来越普及的无线通信方式。红外通信是以红外线为载体来传送数据信息,具有操作简单、可靠性高、功耗低、抗干扰能力强、空间接入灵活、无需连接线等优点,所以越来越受到重视。数据采集系统是在多种场合都有着重要应用的系统,现场的某些参数要通过传感器采集后送到前台机的数据接收端进行初步的处理,然后前台机要把这些数据传输给后台机进行更进一步的分析和处理,以便于掌握现场的实际情况并采取进一步的措施。
