Globalization presents social scientists with a wide variety of issues and challenges that cut across disciplinary boundaries. Disciplinary boundaries encourage specialization and advances in understanding aspects of social behavior, but specialization also creates barriers to more comprehensive understanding of social behavior such as globalization. Successful interdisciplinary efforts entail gains from trade across disciplinary specializations. The papers in this volume help outline an agenda for interdisciplinary investigation of globalization to knock down disciplinary boundaries and encourage gains from trade that further our understanding of globalization. But much work remains before we see real fruits from such efforts.  相似文献

Mortality effects of exposure to air pollution and other environmental hazards are often described by the estimated number of “premature” or “attributable” deaths and the economic value of a reduction in exposure as the product of an estimate of “statistical lives saved” and a “value per statistical life.” These terms can be misleading because the number of deaths advanced by exposure cannot be determined from mortality data alone, whether from epidemiology or randomized trials (it is not statistically identified). The fraction of deaths “attributed” to exposure is conventionally derived as the hazard fraction (R – 1)/R, where R is the relative risk of mortality between high and low exposure levels. The fraction of deaths advanced by exposure (the “etiologic” fraction) can be substantially larger or smaller: it can be as large as one and as small as 1/e (≈0.37) times the hazard fraction (if the association is causal and zero otherwise). Recent literature reveals misunderstanding about these concepts. Total life years lost in a population due to exposure can be estimated but cannot be disaggregated by age or cause of death. Economic valuation of a change in exposure-related mortality risk to a population is not affected by inability to know the fraction of deaths that are etiologic. When individuals facing larger or smaller changes in mortality risk cannot be identified, the mean change in population hazard is sufficient for valuation; otherwise, the economic value can depend on the distribution of risk reductions.  相似文献

The author argues that the burden of proof for the safety and efficacy of some medical devices properly lies with the manufacturers of the devices and with the providers who use them. The controversy over breast implants is used as a case for this shift in the burden of proof of safety and effectiveness.  相似文献

Policies to mitigate potential damages from global climate change impose costs on the current generation to provide benefits to future generations. This article examines how comparisons among three stylized policies-business-as-usual, mitigation of climate change, and compensation for climate damages-depend on social preferences with respect to risk and intertemporal equity. Also examined is the opportunity-cost criterion, which asserts that mitigation should not be chosen if its net present value is smaller than that of business-as-usual. Analysis reveals that the discount factor used to evaluate whether mitigation satisfies this criterion depends on preferences regarding risk and intertemporal inequality of consumption, and on the risk of the compensation policy. Risk aversion favors mitigation over business-as-usual. If society is neutral to inequality, risk aversion disfavors compensation, but if society is inequality averse, the effect of risk aversion on preferences between compensation and business-as-usual is ambiguous. Inequality aversion tends to favor business-as-usual over both alternative policies provided that, roughly speaking, the anticipated future improvements in welfare exceed the anticipated climate damages.  相似文献

The relationship between leadership and sports was analyzed. Peer influence was most important, with that of teachers and parents seeming to have a second-order effect as perceived through peers. Each gender benefitted more in leadership when mentored by their own gender, especially so for women. In work settings, men reported more leadership learning and encouragement than did women. Women experienced more frustration in participating in games and sports in school, the encouragement and continued mentoring being insufficient. Harragan's 1977 thesis that the corporate world and the playing field of sports and high-level policy-making have a male schema was borne out.  相似文献

We examined how personal values and perceptions of risks and benefits are associated with the acceptability of nuclear energy (NE). A theoretical model is tested in which beliefs about the risks and benefits of NE mediate the relationship between values and acceptability. The results showed that egoistic values are positively related to the perceived benefits and acceptability of NE. In contrast, altruistic and biospheric values were positively related to the perceived risks of NE. Although it has been argued that NE may help to combat climate change through lower CO2 emissions, these environmental benefits were not acknowledged by people with strong biospheric values. Furthermore, results confirmed that the more risks respondents perceived, the less they were inclined to accept NE. In contrast, the more a person believed that NE has beneficial consequences, the more acceptable NE was. Finally, as expected, perceived risks and benefits were found to partly mediate the relationship between personal values and acceptability. We discuss the theoretical and practical implications of these findings.  相似文献

We develop a Ricardian trade model that incorporates realistic geographic features into general equilibrium. It delivers simple structural equations for bilateral trade with parameters relating to absolute advantage, to comparative advantage (promoting trade), and to geographic barriers (resisting it). We estimate the parameters with data on bilateral trade in manufactures, prices, and geography from 19 OECD countries in 1990. We use the model to explore various issues such as the gains from trade, the role of trade in spreading the benefits of new technology, and the effects of tariff reduction.  相似文献

Management of health care is compromised by its singular reliance on billing information--i.e., a claims trail tells little of what providers think. It relates to neither prevention of disease nor reduction of unnecessary health care costs. Billing information is not the substrate to be used in the pursuit of appropriateness, effectiveness, and value. To improve medical management of health care, a protected, but accessible clinical database is needed.  相似文献

Increasing numbers of pregnant women are working throughout much, if not all, of their pregnancies. In this secondary analysis of existing longitudinal data on family health, pregnant women were grouped according to employment status: 126 homemakers, 70 employed part-time, and 135 employed full-time. There were no significant differences between the groups in measures of distress, including depression, trait and state anxiety, and perception of negative life events. Homemakers were significantly younger, less educated, and had lower family incomes than either group of employed women. There was also a non-significant trend towards higher distress scores among homemakers. Overall, among these women, it was the similarities which were more striking than the differences, which supports recent research findings about distress among pregnant women.  相似文献

In light of increasing losses from floods, many researchers and policymakers are looking for ways to encourage flood risk reduction among communities, business, and households. In this study, we investigate risk‐reduction behavior at the household level in three European Union Member States with fundamentally different insurance and compensation schemes. We try to understand if and how insurance and public assistance influence private risk‐reduction behavior. Data were collected using a telephone survey (n = 1,849) of household decisionmakers in flood‐prone areas. We show that insurance overall is positively associated with private risk‐reduction behavior. Warranties, premium discounts, and information provision with respect to risk reduction may be an explanation for this positive relationship in the case of structural measures. Public incentives for risk‐reduction measures by means of financial and in‐kind support, and particularly through the provision of information, are also associated with enhancing risk reduction. In this study, public compensation is not negatively associated with private risk‐reduction behavior. This does not disprove such a relationship, but the negative effect may be mitigated by factors related to respondents' capacity to implement measures or social norms that were not included in the analysis. The data suggest that large‐scale flood protection infrastructure creates a sense of security that is associated with a lower level of preparedness. Across the board there is ample room to improve both public and private policies to provide effective incentives for household‐level risk reduction.  相似文献

Leaders, followers, and time   总被引:5,自引:4,他引:1  
In order to consider leadership from a temporal perspective, we examine extant leadership research that refers to temporal variables in its theorizing and/or empirical testing. We consider rhythmic patterns manifested in leader and follower behavior and employ entrainment, polychronicity, pace/speed, punctuality, and temporal depth as categorization concepts for the analysis. Further, we propose general theoretical statements about temporal dimensions and their prospective roles in relationships and processes related to leadership.  相似文献

In 2005, Swiss citizens endorsed a moratorium on gene technology, resulting in the prohibition of the commercial cultivation of genetically modified crops and the growth of genetically modified animals until 2013. However, scientific research was not affected by this moratorium, and in 2008, GMO field experiments were conducted that allowed us to examine the factors that influence their acceptance by the public. In this study, trust and confidence items were analyzed using principal component analysis. The analysis revealed the following three factors: "economy/health and environment" (value similarity based trust), "trust and honesty of industry and scientists" (value similarity based trust), and "competence" (confidence). The results of a regression analysis showed that all the three factors significantly influenced the acceptance of GM field experiments. Furthermore, risk communication scholars have suggested that fairness also plays an important role in the acceptance of environmental hazards. We, therefore, included measures for outcome fairness and procedural fairness in our model. However, the impact of fairness may be moderated by moral conviction. That is, fairness may be significant for people for whom GMO is not an important issue, but not for people for whom GMO is an important issue. The regression analysis showed that, in addition to the trust and confidence factors, moral conviction, outcome fairness, and procedural fairness were significant predictors. The results suggest that the influence of procedural fairness is even stronger for persons having high moral convictions compared with persons having low moral convictions.  相似文献

Despite the possibility of burnout resulting from dynamics in firms' upper echelons, little if any work has focused on chief executive officer's (CEO's) burnout and firm performance. Drawing on managerial discretion theory, this article analyzes the influence of CEO burnout on firm performance and the moderating roles of the individual (CEO locus of control), structural power (CEO duality and CEO tenure), and organizational characteristics (size, age, and resource availability) related to managerial discretion. Using a sample of 156 CEOs in Swedish firms, we find a negative association between CEOs who report higher burnout and firm performance. Our results confirm that CEO duality and resource availability ameliorate and firm size exacerbates the negative association between CEO burnout and firm performance. Contrary to our expectations, CEO locus of control, CEO tenure, and firm age do not influence this relationship. We discuss the implications of our research for upper echelons theory and strategic leadership theory.  相似文献

Gender, Race, and Perception of Environmental Health Risks   总被引:17,自引:2,他引:17  
This paper reports the results of a national survey in which perceptions of environmental health risks were measured for 1275 white and 214 nonwhite persons. The results showed that white women perceived risks to be much higher than did white men, a result that is consistent with previous studies. However, this gender difference was not true of nonwhite women and men, whose perceptions of risk were quite similar. Most striking was the finding that white males tended to differ from everyone else in their attitudes and perceptions–on average, they perceived risks as much smaller and much more acceptable than did other people. These results suggest that sociopolitical factors such as power, status, alienation, and trust are strong determiners of people's perception and acceptance of risks.  相似文献
