The European Commission’s proposal for a Directive on the award of concession contracts has sparked vigorous public debate and intense opposition. This Directive is controversial because of the nature of the policy it proposes and because the sectors involved are highly sensitive. This Forum examines the weaknesses of the Commission’s proposal and presents an overview of the current issues in water regulation and the provision of water services. The authors analyse the regulation of natural monopolies, water efficiency and upstream competition in the water industry.  相似文献

The purpose of this study was to compare parents’ and children’s attitudes and habits towards use of bicycle helmets and car seat belts. We hypothesized that parental perception of their children’s safety practices did not reflect actual behavior and further, that parental practices, rather than their beliefs about a particular safety practice, have a greater affect on their child’s risk-taking behavior. The study population consisted of children in grades four and five and their parents/guardians. Participation in the cross-sectional study was voluntary and confidential anonymous questionnaires were used. In separate and independent surveys, children and parents were questioned in parallel about their knowledge, habits and attitudes toward bicycle helmet use and car safety practices. In the study, 731 students participated with 329 matched child-parent pairs. Ninety-five percent of the children own bicycles and 88% have helmets. Seventy percent of parents report their child always wears a helmet, while only 51% of children report always wearing one (p < 0.05). One-fifth of the children never wear a helmet, whereas parents think only 4% of their children never use one (p < 0.05). Parents report their children wear seat belts 92% of the time while 30% of children report not wearing one. Thirty-eight percent of children ride bicycles with their parents and wear their helmets more often than those who do not ride with their parents (p < 0.05). Parents who always wear a seat belt are more likely to have children who sit in the back seat and wear a seat belt (p < 0.05). Parents’ perceptions of their children’s safety practices may not be accurate and their actions do affect their children’s. Injury prevention programs that target both parents and children may have a greater impact on reducing risk-taking behaviors than working with each group in isolation.  相似文献

The recent drive among consumers to purchase fresh, healthy and environmentally friendly food has brought about a renewed interest in farmers’ markets. However, ensuring the success of a farmers’ market is not an easy task. Unlike general grocery stores, farmers’ markets often have very limited hours of service and are distributed sparsely in space. Both spatial and temporal constraints that people experience in their daily lives limit their accessibility to a farmers’ market. This research incorporates such constraints in the service provision planning of farmers’ markets. In particular, two models are proposed to select locations and the associated service schedules for a fixed number of farmers’ markets. A case study is conducted in Tucson, Arizona to demonstrate the merits of the new approach.  相似文献

This study tests the stability of a standard equation for aggregate US imports over the period 1975–2011. It finds evidence of significant parameter instability, though its dating varies with the equation specification and diagnostic. Nonetheless, the analysis finds a significant rise in the long-run income elasticity that is robust across most break dates and specifications. The increase in the long-run income elasticity is consistent with shifts in the composition of aggregate imports toward capital and consumer goods. There is further evidence that vertical specialization may be behind both the structural instability and the apparent rise in the income elasticity of aggregate US imports.  相似文献

An important internal link in the supply chain is between supply managers and their internal customers. These individuals must collaborate to determine purchase specifications, develop sourcing strategies, ensure supplier performance, and maintain effective supplier relationships. Using power and social networking as the theoretical lenses, we develop and test a conceptual model examining the supply management function’s status, supply manager’s networking behavior, collaboration with the internal customer, and operating performance (lower cost, better quality, faster delivery, and consistent delivery). We also examine the mediating effect of collaboration and networking behavior on the positive effect of status and operating performance. Data gathered in an online survey of supply management professionals are examined using path analysis. Results show that without including the mediators, supply management status is directly related to all four operating performance measures. It is also positively related to collaboration with the internal customer and networking behavior. Contrary to expectations, the supply manager’s networking behavior is not related to collaboration with the internal customer. Collaboration is positively related to all four operating performance measures. However, the supply manager’s networking behavior is only related to one operating performance measure, better quality. Mediation analysis shows that supply management status has a direct effect on faster delivery performance beyond what is explained by collaboration and the supply manager’s networking behavior. The findings suggest that organizations should look for ways to elevate the status of the supply management function to improve internal collaboration and operating performance.  相似文献

Codes of Ethics as Signals for Ethical Behavior   总被引:1,自引:1,他引:0  
This study investigated effects of codes of ethics on perceptions of ethical behavior. Respondents from companies with codes of ethics (n = 465) rated role set members (top management, supervisors, peers, subordinates, self) as more ethical and felt more encouraged and supported for ethical behavior than respondents from companies without codes (n = 301). Key aspects of the organizational climate, such as supportiveness for ethical behavior, freedom to act ethically, and satisfaction with the outcome of ethical problems were impacted by the presence of an ethics code. The mere presence of a code of ethics appears to have a positive impact on perceptions of ethical behavior in organizations, even when respondents cannot recall specific content of the code.  相似文献

Is Cross-Cultural Similarity an Indicator of Similar Marketing Ethics?   总被引:1,自引:0,他引:1  
This study compares Australian marketers with those in the United States along lines that are particular to the study of ethics. The test measured two different moral philosophies, idealism and relativism, and compared perceptions of ethical problems, ethical intentions, and corporate ethical values. According to Hofstede's cultural typologies, there should be little difference between American and Australian marketers, but the study did find significant differences. Australians tended to be more idealistic and more relativistic than Americans and the other results were mixed, making it difficult to generalize about the effects of moral philosophies on the components of ethical decision-making measured here. This is an important finding; as firms become increasingly more globalized, marketers will more often be involved in cross-cultural ethical dilemmas and it seems natural to assume that similar cultures will have similar ethical orientations. That assumption may well prove erroneous.  相似文献

When successful and ethical managers are alerted to possible organizational wrongdoing, they take corrective action before the problems become crises. However, recent research [e.g., Rynes et al. (2007, Academy of Management Journal 50(5), 987–1008)] indicates that many organizations fail to implement evidence-based practices (i.e., practices that are consistent with research findings), in many aspects of human resource management. In this paper, we draw from years of research on whistle-blowing by social scientists and legal scholars and offer concrete suggestions to managers who are interested in encouraging internal reporting of problems requiring attention, and to observers of questionable activity who are considering reporting it. We also identify ways that research suggests policy-makers can have a more positive influence. We hope that these suggestions will help foster evidence-based practice regarding whistle-blowing.  相似文献
