Canadian regulations have different rules for foods and natural health products (NHPs) regarding allowable health claims, requirements for use in clinical trials and good manufacturing standards and labeling requirements. How these rules apply to products at the food–NHP interface is often unclear. This paper describes the regulatory environment and explores two product examples – probiotic yogurt and green tea – to illustrate the issue. In addition, results from a qualitative study of NHP/food researchers highlights the confusion and frustration of those working in the field. Interim agreements between the NHP and Foods Directorate of Health Canada regarding products reviews provide a temporary response but regulatory amendments, accompanied by clear guidance to stakeholders, are needed.  相似文献

This research utilizes a compensating differential framework to measure the social benefits of minor league baseball teams. Consistent with findings at the major league level, individual housing observations from 138 metropolitan areas between 1993 and 2005 show that affiliated teams are associated with a significant 6 to 8% increase in rents in mid‐sized markets ranging from 0.4 to 1.4 million people. On the other hand, independent teams and stadiums are associated with insignificant effects on rents. The positive effect of affiliated minor league teams suggests they are a valuable urban amenity that can contribute to local quality of life. (JEL H23, H41, H71, R50, L83)  相似文献

We often credit disasters, and their coverage in the media, with changes in the public perception of risk associated with low-probability, high-consequence events (LPHCs). With a change in perceptions, we also expect changes in beliefs, preferences, and behaviors. Do beliefs and behaviors change in different ways for people who live through these LPHC critical events, as opposed to people who observe them? This study compares hypothetical hurricanes with actual hurricane effects in a survey quasi-experiment. Findings indicate that hypothetical disasters induce stronger reactions than those experienced in the natural world, as Hurricane Katrina bystanders imagine themselves incurring much higher damages, and being much less likely to return to live in their hurricane-damaged homes, than actual Hurricane Katrina evacuees. Ultimately, respondents considering a hypothetical low-probability, high-consequence event exhibit exaggerated beliefs and opposite decisions of those who actually lived through one of these events. Results underline the importance of examining the differences between public perceptions and experiential reality.  相似文献

Does the distribution of foreign development assistance depend on the organizational capacity of the recipient organization? I argue that employees at donor agencies seek signals of which recipients will implement aid most effectively, and use these signals to determine the destination of foreign aid on the micro level. Qualitative evidence gathered in the US and Brazil indicates the types of signals donors seek and recipients strive to transmit: signals of a recipient's professionalism, reputation, and sustainability. After developing a signaling game to derive the conditions under which these signals might be credible indicators of implementation effectiveness, I present quantitative evidence of aid recipient organizations in Brazil and score them on the three signals. Statistical tests confirm that organizations with higher levels of these signals are more likely to receive funding, suggesting that donors use these signals to determine the destination of development assistance.  相似文献
