Trust in government policy affects the way people perceive and handle risks. In our study, we investigated the relationships between trust in government policy regarding electromagnetic fields (EMF), perceived risk and perceived benefits of public and personal EMF sources, perceived control over exposure to EMF and responses to the possible EMF health risk (e.g. protest against placement of mobile phone base stations or power lines, or taking own measures against EMF exposure). Previous research indicated that perceived risk and benefits mediate the relationship between trust and people’s risk responses. Additionally, we suggest that perceived control over EMF exposure affects the relation between trust in government policy and perceived risk, and, consequently, the risk responses. We performed a survey among the Dutch population (n?=?1009), which contained questions about risk responses to EMF, perceived risk and benefits of several EMF sources, trust in government policy and perceived control over EMF exposure. Comparing public EMF sources, i.e. power lines and mobile phone base stations, to personal EMF sources, i.e. microwave ovens and cordless and mobile phones, we tested our hypotheses. Variations in risk responses to both public and personal EMF sources were mainly explained by risk perception. In addition, perceived risk partially mediated the relationship between trust in government policy and risk responses. For public sources, perceived control over exposure weakened the negative relationship between trust and perceived risk. We conclude that, especially in people with low perceived control, a lack of trust in government policy may enhance perceptions of health risks, thereby increasing their inclination for risk responses. 相似文献

Starting with the distinction of natural science, engineering science ("technology") and engineering practice ("technics"), the paper will stress the difference between technological and technical knowledge. The first part will discuss the relationship between science and technology, arguing that technology is a genuine type of knowledge rather than "applied science". In technics, however, even technological laws, as transformations of scientific laws, cover a certain part of knowledge only. The greater part of technical knowledge includes technical know-how, functional rules, structural rules, and socio-technological understanding, which is just developing in our times. The classification of knowledge types will be used for determining which kind of knowledge may seem appropriate to general technological education. 相似文献

Process industries often have features that differ from other businesses, such as round‐the‐clock production and costly and specialized production processes—features that have not been dealt with in the project management literature. We highlight and identify the complexity of R&D projects in the Swedish process industry and its interrelated process development and product development activities based on results from interviews and a case study. The different competence areas in which a project manager must integrate and manage R&D projects is illustrated. We conclude that a project manager needs both production and product‐related competence, including customers' processes. 相似文献

The popular investment strategy in the literature is to use only past performance to select mutual funds. We investigate whether an investor can select superior funds by additionally using fund characteristics. After considering the fund fees, we find that combining information on past performance, turnover ratio, and ability produces a yearly excess net return of 8.0%, whereas an investment strategy that uses only past performance generates 7.1%. Adjusting for systematic risks, and then using fund characteristics, increases yearly alpha significantly from 0.8% to 1.7%. The strategy that also uses fund characteristics requires less turnover. 相似文献

This paper examines the effect of investors’ status (current and prospective) on their evaluation of information varying in valence (negative and positive) and temporality (past and future). Master of Business Administration graduates, proxying for current or prospective investors, rated the relevance of negative, positive, past, and future Management Discussion and Analysis information. Investors’ relevance ratings of information resulted in the following ranking (from highest to lowest): negative‐future, negative‐past, positive‐future, and positive‐past information. Furthermore, prospective investors (relative to current) rated positive and future information as more relevant and negative information as less relevant. Implications for effective disclosure strategies and policies are discussed. 相似文献

The paper investigated the moderating effects of supervisory adaptive selling behaviors on the feedback-performance relationship in industrial salespersons. A conceptual model was developed and three research hypotheses were empirically examined. The data were collected via a survey of a national random sample of industrial salespersons in US. The results indicated that adaptive selling behaviors by sales managers moderated the effects of positive behavioral feedback on salesperson performance. Positive output feedback had a significantly positive effect on salesperson performance, whereas negative feedback (output and behavior) was unrelated to salesperson performance. Thus, sales managers can improve the productivity of their salespeople by demonstrating adaptive selling techniques while providing positive feedback to them. Managerial implications were discussed. 相似文献

During the past 15 years, companies have flocked to a handful of cities in India and Eastern Europe for offshore service functions. As a result, the most popular sites are now overheating: Demand for young professionals is outstripping supply, wages and turnover are soaring, and overburdened infrastructure systems are struggling to serve the explosive growth. The happy news is that the tight labor markets in the well-known hot spots are the exceptions, not the rule. Many attractive alternatives are emerging around the world. According to a McKinsey Global Institute study, more than 90% of the vast and rapidly growing pool of university-educated people suitable for work in multinationals are located outside the current hot spot cities. For instance, Morocco is now home to offshore centers for French and Spanish companies requiring fluent speakers of their home languages. Neighboring Tunisia has used its modern infrastructure, business-friendly regulations, and stable, low-cost workforce to attract companies such as Siemens and Wanadoo. Vietnam offers university graduates who have strong mathematics skills; speak French, English, German, or Russian; and do not demand high wages. The problems facing the hot spots, coupled with the emergence of many more countries able and willing to provide offshore services, mean that picking a site has become more complicated. In choosing a location, companies will have to focus less on low wages and much more on other ways that candidate cities can fulfill their business needs. They will have to be much more rigorous in articulating precisely what they require from an offshore location. That means evaluating their unique needs on a range of dimensions and understanding how alternative locations can meet those needs for the foreseeable future. 相似文献
