结构问题是21世纪中国人口的核心问题

认为数量问题是 2 0世纪中国人口问题的关键 ,其标志是决定人口数量的主要因素——生育率和死亡率都在 2 0世纪经历了以人口转变为重要概括的历史性转折。虽然人口数量问题并没有随人口转变的完成退出历史舞台 ,但其地位已发生改变。在 2 1世纪结构问题将成为中国人口问题的核心 ,并且分别表现在人口年龄结构、人口地域结构以及人口性别结构等诸多方面     

The Perfect Fit: The Moderating Role of Selling Cues on Hedonic and Utilitarian Product Types

With the need among retailers to create effective promotional campaigns, scarcity, and popularity cues are increasingly used. Drawing from regulatory focus and popularity versus scarcity cues literature, this research explores the impact of popularity versus scarcity cues and product types on consumer perceptions of risk, product uniqueness, and purchase intentions. Results from three studies provide primary insights: (1) A utilitarian product aligns with prevention goals and hence the popularity cue will enhance consumers’ purchase intentions, and (2) a hedonic product aligns with promotion goals and hence the scarcity cue will enhance consumers’ purchase intentions. Further, we theorize that perceived risk and perceived product uniqueness will act as psychological mechanisms. We discuss theoretical contributions and strategic insights for retailers and marketers that the findings indicate.

基于STM32的太阳模拟器控制系统设计

聚焦型太阳模拟器应用于光热发电相关试验,主要由风冷系统、光学系统、机械系统、控制系统组成。为了消除系统的人工安装误差、减小光斑调整误差,设计了基于STM32处理单元,结合PID算法,采用RS485通信标准,以液晶触摸屏为输入输出单元的太阳模拟器控制系统。该系统主要包括氙灯光强度控制、氙灯阴极温度控制、氙灯单元俯仰、平移控制等模块。通过对控制系统的搭建,实现了光斑面积与焦平面的位置调整,以及氙灯阴极温度的检测与控制,有效解决了多光源系统焦点光斑汇聚重合的问题。     

Job analysis: a strategic human resource management practice

This study examined the impact of job analysis on organizational performance among 148 companies based in the United Arab Emirates (UAE), a Gulf-region country. Survey results indicated that a practice of proactive job analysis was strongly related to organizational performance. This relationship was strongest to the extent that companies maintained HR information systems, accorded HR greater involvement in strategic planning and emphasized competency-based characteristics of employees in the job analysis approaches they used. The findings suggest that a company-wide policy of job analysis is an important source of competitive advantage in its own right, and merits due attention of HR professionals, line managers and top management. The study extends the findings of the HR–performance research pursued in Western countries to a non-Western context.     

Client focus in regulatory agencies

Abstract

‘Client focus’ seems like a counter-intuitive notion for regulatory agencies, whose job is to compel people to comply with government requirements. Yet it is becoming the catchphrase for many regulatory authorities. This article puts forward an argument, based on social exchange and regulatory theory, that a client-focused approach is not only compatible with a regulatory role, but also actually facilitates it. It recognizes that most people's propensity to comply is a function of factors other than the fear of punishment, such as their intrinsic or normative motivations and their ability to do what is required. It also assists in delineation and understanding of the proportion of regulatees who opportunistically avoid their obligations. The article advances a broader model of social exchange between regulators and regulatees.     

Consumer perceptions of risks of chemical and microbiological contaminants associated with food chains: a cross-national study

The development and implementation of effective systems to identify vulnerabilities in food chains to chemical and microbiological contaminants must take account of consumer priorities and preferences. The present investigation attempted to understand consumer perceptions associated with chemical and microbiological contaminants in four specific food chains (drinking water, farmed salmon, chicken and milk powder). To this end, ten focus group discussions were held in five different countries (Poland, Ireland, the Netherlands, France and Brazil). Consumers expressed higher concerns about chemical, as compared with microbial, contaminants. Chemical contaminants were more strongly associated with the potential for severe consequences, long-term effects and lack of personal control. Traceability was considered by consumers as a useful tool that offers the potential to improve consumer confidence in food safety.

Technology readiness and usage: a global-identity perspective

The past several decades have witnessed the rapid globalization of consumption markets and widespread diffusion of information and communication technologies. However, the use of technology by consumers is not a foregone conclusion. We investigate the role of global self-identity on the orientation toward technology readiness and usage. Relying on a social-identity model of motivation as our theoretical framework, we propose a model which incorporates global self-identity (i.e., cosmopolitanism/parochialism and global/local identification) and self-regulation (i.e., promotion and prevention focus) in predicting technology readiness and usage in a self-service technology context. The proposed model is tested in two different cultures, the U.S. and China, and is contrasted with two theoretically-competing models as well. Results provide support for the hypothesized model, and a number of limitations, implications, and directions for future research are discussed.
