The paper examines the roles of health consciousness, food safety concern and ethical self‐identity in predicting attitude and purchase intention within the context of organic produce. A conceptual model is derived and tested via structural equation modelling. Findings indicate food safety as the most important predictor of attitude while health consciousness appears to be the least important motive in contrast to findings from some previous research. In addition, ethical self‐identity is found to predict both attitudes and intention to purchase organic produce, emphasizing that respondents' identification with ethical issues affects their attitude and subsequent consumption choices.  相似文献

本文表达了如下想法:①名义汇率围绕真实汇率上下波动的调整,会促使一国国际收支恶化或者改善;②美元对人民币贬值并不一定能够满足马歇尔———勒纳条件和解决中美国际收支失衡问题,因为失衡问题主要是美国的国内因素以及限制对华技术出口与中国商品进口所引起的;③我国作为一个发展中国家,应该适度控制名义汇率,使其低于真实汇率,才能支持劳动力优势,保持国际收支顺差;④国际收支长期盈余,是我国经济增长和经济安全的保证。  相似文献

超前性是安全科学发展的基本趋势.我国安全生产法片面强调实害犯,使得预防为主的原则得不到很好的贯彻落实.过失危险理论及国外相应的立法实践为我们提供了有益的借鉴.在把握过失危险行为犯罪化与谦抑性原则和法益保护理念的统一中提出"违犯法令禁止的危险行为"这一新的概念,为安全法学的重构提供一个新的逻辑起点.  相似文献

Despite persistent claims in the motor carrier industry of poorer safety performance of owner–operators, there is little empirical work directly comparing owner–operator safety performance to that of employee drivers. This study assesses the statistical significance of differences in the safety performance between owner–operators and employee drivers. This study also expands on previous driver focused safety models by examining how driver and carrier characteristics affect safety performance. Data for this study were derived from the Motor Carrier Management Information System (MCMIS), and the Commercial Driver’s License Information System (CDLIS) databases. Study results provide evidence that owner–operators are associated with more driver- and vehicle-out-of-service violations but experience lower crash rates than do employee drivers.  相似文献

This paper investigates the factors affecting the outsourcing decision of occupational safety and health (OSH) services. I posit several hypotheses following the three main approaches to the make or buy question: (1) the transaction cost theory, (2) the resource‐based view of the firm, and (3) the behavioral decision‐making framework. The empirical analysis draws on microdata from 3,047 Spanish firms that are legally obliged to provide organized OSH activities but free to choose the option to outsource. Results show that informational symmetries and increasing transaction costs mainly explain the decision to outsource the OSH activity. Organizational behavior variables, such as management commitment to safety and workers' representation, also relate to the outcome of the decision but not necessarily as hypothesized. Finally, I did not generally observe the strategic value of safety in informing the make or buy decision. © 2009 Wiley Periodicals, Inc.  相似文献

Upgrade of the Ejisu-Kumasi section of the N6 saw the construction of roundabouts at selected intersections. Their use appears challenging particularly for vehicles with elevated Centre-of-Gravity. The objective of this study was to establish the relative risk of traffic accident deaths or hospitalized injuries at the roundabouts. Five-year crash data covering a 100 m stretch upstream and downstream of the roundabouts were analysed. A total of 119 crashes occurred with 18% casualty hospitalization and 12%fatalities. Compared with the Ejisu roundabout, fatal or hospitalized injuries were significantly higher at the Boadi (OR = 25.6, p = 0.0021) and Kwame Nkrumah University of Science and Technology Police Station Junctions (OR = 48.2, p < 0.001). Occupants of buses, heavy goods vehicles and riders of two wheelers were at elevated risk of deaths or serious injuries. Crash severity at the round abouts was aggravated by night-time, steep gradients and adverse cambers. It is recommended that, signalization and grade separation should be used in the current arrangement where appropriate.  相似文献
