Gender, Values, and Environmentalism 总被引:3,自引:0,他引:3
Objective . The social psychological values altruism, self-interest, traditionalism, and openness to change are key correlates of environmental concern and proenvironmental behavior. We investigate the relationship between gender and these values to better understand gender differences in environmentalism. We consider both gender differences in value priorities (differences in mean response on value scales) and differences in the meaning of values (differences in the factor structure of values) as well. Methods . Our analysis is based on data from a random-digit dialed national telephone survey of U.S. adults conducted in 1994. We examine differences in factor structure of values for a group of 145 white men and 200 white women using confirmatory factor analysis and differences in mean value scores using multivariate analysis of variance. Results . We find no substantial differences in value factor structure, but differences in value priorities, with women ranking altruism as more important than men. Conclusions . Our analysis supports work that focuses on mean differences in environmentalism across genders without examining gender differences in factor structure, although further examination of gender differences in factor structure is warranted. Our results also highlight the importance of gender differences in altruism as a basis for gender differences in environmentalism. 相似文献

Bridging Environmental Science with Environmental Policy: Plasticity of Population, Affluence, and Technology 总被引:11,自引:0,他引:11
Objective . Sound environmental policy is fully dependent upon sound science. However, we have little scientific knowledge of the driving forces behind environmental change. We use the well-known I = PAT formulation (environmental i mpacts are the multiplicative product of p opulation, a ffluence, and t echnology) as a framework to assess the relative impacts of driving forces. Methods . We introduce the concept of plasticity —the potential for each factor to vary, particularly because of purposive human action (e.g., policy)—to fine tune our understanding of how each factor can influence different impacts. We illustrate plasticity by assessing each driving force for a variety of environmental impacts. Results . We demonstrate that population, affluence, and technology have different potentials for mitigating different types of impacts and that no one factor is of greater importance than the others. Conclusions . We conclude that plasticity measures can guide policymakers toward identifying and prioritizing those environmental problems most responsive to policy solution. 相似文献

Previously proposed linear signed rank tests for multivariate location are not invariant under linear transformations of the observations, The asymptotic relative efficiencies of the tests 2 with respect to Hotelling's T2test depend on the direction of shift and the covariance matrix of the alternative distributions. For distributions with highly correlated components, the efficiencies of some of these tests can be arbitrarily low; they approach zero for certain multivariate normal alternatives, This article proposes a transformation of the data to be performed prior to standard linear signed rank tests, The resulting procedures have attractive power and efficiency properties compared to the original tests, In particular, for elliptically symmetric contiguous alternafives, the efficiencies of the new tests equal those of corresponding univariate linear signed rank tests with respect to the t test. 相似文献

Since the turn of the 21st century, there has been a revival of interest in nuclear power. Two decades ago, the expansion of nuclear power in the United States was halted by widespread public opposition as well as rising costs and less than projected increases in demand for electricity. Can the renewed enthusiasm for nuclear power overcome its history of public resistance that has persisted for decades? We propose that attitudes toward nuclear power are a function of perceived risk, and that both attitudes and risk perceptions are a function of values, beliefs, and trust in the institutions that influence nuclear policy. Applying structural equation models to data from a U.S. national survey, we find that increased trust in the nuclear governance institutions reduces perceived risk of nuclear power and together higher trust and lower risk perceptions predict positive attitudes toward nuclear power. Trust in environmental institutions and perceived risks from global environmental problems do not predict attitudes toward nuclear power. Values do predict attitudes: individuals with traditional values have greater support for, while those with altruistic values have greater opposition to, nuclear power. Nuclear attitudes do not vary by gender, age, education, income, or political orientation, though nonwhites are more supportive than whites. These findings are consistent with, and provide an explanation for, a long series of public opinion polls showing public ambivalence toward nuclear power that persists even in the face of renewed interest for nuclear power in policy circles. 相似文献

In this meta-analysis, correlations of personality traits and career decision-making self-efficacy with self and environmental career exploration were estimated across 71 samples and a pairwise sample of 19,846. Traits included the Big Five personality traits, shyness, locus of control, vocational decision styles, and stress. Many measures of career exploration were based on scores of self and environmental exploration on the Career Exploration Survey. Results varied by characteristics with the largest effects for locus of control, vocational decision style: thinking-feeling and self-efficacy. Environmental exploration and self-exploration were moderately correlated and demonstrated different relations with traits that were consistent with theory. Self-exploration was related to openness to experience and unrelated to extraversion, while environmental exploration was correlated with extraversion. Both were similarly correlated with conscientiousness such that conscientious individuals were more likely to engage in career exploration. 相似文献

Expansion decisions by corporate managements are importantly influenced by their perceptions of the firm's cost of capital and especially the cost of common equity. Their decision making is then influenced by the common perception that new issues of common stock are more costly than retained earnings because of the flotation costs inherent in new issues. Thus a rate of expansion that requires new issues is downgraded in decision making. In this paper the authors show that in actuality new issues of common equity may be less costly than retained earnings. Thus different decision-making implications are clearly involved. 相似文献
