浅谈爆炸硬化辙叉在朔黄线的应用

随着西煤东运第二条大通道朔黄铁路运量的增加,运输压力越来越大。自90年代以来,铁路运输飞速发展,提速、重载给工务线路带来了一系列问题,尤其是辙叉已远远不能满足铁路提速重载的要求。2011年开始朔黄铁路在黎明居车站3号、4号岔位和神池南车站2083#、2043#岔位陆续试用了60-12#和75-12#爆炸硬化辙叉。实践表明,爆炸硬化辙叉提高了道岔使用寿命,增大了安全系数,创造更多的经济效益和社会价值。     

The Effects of Native Ads on Consumer Brand Engagement: The Moderating Role of Website Credibility

Abstract

This research examined the effect of native ads on consumer brand engagement – specifically, how source disclosure of ad sponsors affected consumers’ perceived ad deceptiveness as well as their attitude toward the company and the brand. It also explored the moderating role of website credibility. One hundred and ten college students in South Korea participated in the experimental study, which found that high source disclosure of ad sponsors positively affected perceived deceptiveness. The effect of source disclosure on perceived deceptiveness was moderated by website credibility. Perceived deceptiveness negatively affected consumers’ attitude toward the company and the brand. The mediating role of perceived deceptiveness between source disclosure and consumer brand engagement was confirmed only when website credibility was high. The paper discusses the theoretical and practical implications of the findings as well as suggestions for future research in this area.     

The impact of SARS on China's human resources: implications for the labour market and level of unemployment in the service sector in Beijing,Guangzhou and Shanghai

In this paper, we examine the effects of SARS (Severe Acute Respiratory Syndrome) on China's human resources, its labour-market and its level of employment and unemployment, looking specifically at what was one of its economically most vulnerable points, the hotel industry. The paper hypothesizes that the greatest impact would be on human resources in the service-industries and on particular sub-sectors, such as employment in hotels, located in three main cities in the PRC, in Beijing, Guangzhou and Shanghai, catering to both overseas as well as domestic tourism. It tentatively concludes that the almost dramatic demand and supply ‘shocks’ may have directly affected both the demand for and the supply of labour in the sub-sector, with discernable employment consequences.     

Explaining organizational responsiveness to work‐life balance issues: The role of business strategy and high‐performance work systems

This article applies new insights into business strategies and high‐performance work systems (HPWSs) to examine why organizations adopt work‐life balance programs (WLBPs). Results indicate that a product leadership business strategy is positively related to the likelihood of adopting WLBPs, whereas a cost leadership business strategy is negatively related to the adoption of these programs. Moreover, our analyses establish a mediating role of HPWSs in the relationship between business strategies and the adoption of WLBPs. Our results also demonstrate that different industries vary in adoption of work‐life balance programs. This supports the institutional theory of organizational responsiveness to work‐life balance issues. We tested our hypotheses with two waves of the nationally representative Canadian Workplace and Employee Survey. Implications and specific suggestions for human resource practitioners are discussed. © 2012 Wiley Periodicals, Inc.

The impact of perceived security and consumer innovativeness on e-loyalty in online travel shopping

ABSTRACT

This study investigates the impacts of perceived security and consumer innovativeness on online travel shopping. A survey questionnaire was used to collect data and a total of 283 questionnaires were used for data analysis. The mechanism of perceived security and consumer innovativeness was then identified. The study results indicate that: (1) higher perceived security increases the perception of website image and trust; (2) consumers with a higher level of innovativeness tend to trust travel websites; (3) website image has a mediating effect between perceived security and trust; and (4) trust has a mediating effect between website image and e-loyalty.     

Inflation Developments and Perceptions after the Euro Cash Changeover

Abstract. This paper analyses the evolution of inflation and of consumers' inflation perceptions in the aftermath of the euro cash changeover. It finds that the cross‐country variation of food product inflation was dependent on the complexity of conversion rates, with statistically significant and economically sizeable effects especially for low‐priced items sold in midpriced stores. The paper also shows that cross‐country differences in the mismatch of perceived and actual inflation were linked to differences in the complexity of conversion rates. These results are in line with theories of finite information‐processing capacities on the side of consumers.

Environmental dynamism,human resource flexibility,and firm performance: analysis of a multi-level causal model

While strategic HRM scholars have conceptualized HR flexibility as an important source of sustainable superior firm performance in dynamic environments, the process through which HR flexibility creates value for the firm has not been empirically investigated. Based on a study of 98 manufacturing and 103 service firms from a wide array of industries in India, this paper attempts to illuminate the black box of causal linkages between environmental dynamism, flexibility of human assets, and firm level human-, operational-, and financial-outcomes by developing and testing a multi-level causal model. Evidence indicates that HR flexibility mediates the influence of environmental dynamism on firm performance and that irrespective of the nature of the industry and the degree of environmental turbulence, superior firm performance ensues when HR flexibility as actually possessed by the firm matches the environmental demands for such flexibility as perceived by the firm managers. The results also support the notion of HR value chain that postulates that HR system has direct impact on firm-level HR outcomes which are most proximal, and its effects on increasingly more distal operational- and financial-outcomes are mediated by HR outcomes. The findings of the study suggest that HR practices as a system have both direct and indirect (mediated by behavioral flexibility) effects on firm-level HR outcomes. Existence of significant direct effects signifies that HR practices play an important role as a structural mechanism in achieving superior firm performance.     

Institutional dimensions underlying public trust in information on technological risk

This paper examines the determinants of trust in public information on technological risk in a petrochemical complex located in Tarragona (Spain). Data from focus groups (eight) and a questionnaire survey (N = 400) are drawn together to analyse how two local communities exposed to major chemical hazards perceive information on risk and its sources. Results show how trust relies on two main factors, namely expertise and trustworthiness, that are significantly influenced by a third one, antagonism. Results also illustrate the relevance of the institutional context when understanding how communities give meaning to the available information on risk.
