The author examines links between the timing of various major life events (including women's age at marriage and the spacing of children) and the economic and urban development of a society, using Mexico as an example. The focus is on marriage patterns. She finds that nuptiality influences rural-urban migration for women, as do age and socioeconomic factors and husband's employment status. Data are from the Mexican Fertility Survey for the period 1976-1977. (SUMMARY IN ENG) 相似文献

This paper departs from the Tullock cost paradigm that views competition for monopoly privilege as a welfare-inimical process that wastefully dissipates preexisting producers' surplus and, occasionally, leads to inefficient increases in costs and counterproductive uses of scarce resources. The potential availability of rent-seeking may bring about the elimination of inefficient regulatory regimes that retard or prevent the introduction of cost-reducing innovations. Air quality management is but one area in which innovation rent-seeking holds promise for concrete welfare gains. Researchers may wish to focus on institutional mechanisms designed to overcome the transactions costs and free rider disincentives to the formation of a coalition to seek innovation rents. An example of such a mechanism might be a joint venture that requires all venture members to engage in lobbying and to contribute to collective research efforts. These unaddressed questions await future research.The authors are grateful for the insightful comments of Gordon Tullock, Robert D. Tollison, Michael T. Marlow and J.R. Clark. The usual caveats apply. The views expressed herein are solely those of the authors and should not be taken to represent the views of their employers. 相似文献

The Satisfaction With Life Scale (SWLS) was developed in the United States as a multiitem scale for the overall assessment of life satisfaction as cognitive-judgmental process, rather as a measurement of specific satisfaction areas (e.g., health, energy). The present study attempted to extend the applicability of the SWLS by investigating specific aspects of reliability and validity in a different cultural context (Portugal) with adolescents. In line with previous American findings, reliability figures were found to be favourable. SWLS scores were affected by sex and sociocultural level. In addition, SWLS scores showed to be predictably associated with psychological measures: loneliness, social anxiety, shyness, self- concept, and physical attractiveness. The variables that best predicted satisfaction were overall self-concept, loneliness, and physical attractiveness.Received a Ph.D. in normal and abnormal anthropology from École des Hautes Études en Sciences Sociales (Paris) in 1980 and a Ph.D. in Social Psychology from Faculty of Psychology (Porto) and an Aggregation in Psychology from Faculty of Psychology (Coimbra) in 1990. Research interests include migration and cross-cultural social migration.The author wishes to thank the anonymous reviewers for their helpful comments on an earlier version of this paper. 相似文献

Postmodern inquiry into the discursive construction of identity has the potential to make a distinctive, democratizing contribution to public policy analysis. More so than conventional approaches, a postmodern policy analysis offers the opportunity to interrogate assumptions about identity embedded in the analysis and making of public policy, thereby enabling us to rethink and resist questionable distinctions that privilege some identities at the expense of others. Public policy analysis can benefit from postmodernism's emphasis on how discourse constructs identity. A review of postmodernism and postmodern approaches to interrogating identity is followed by an exercise in postmodern policy analysis. Social welfare policy in contemporary postindustrial America is shown to participate in the construction and maintenance of identity in ways that affect not just the allocation of public benefits, but also economic opportunities outside of the state. Mired in old, invidious distinctions (e.g., independent/dependent, contract/charity, family/promiscuity), welfare policy discourse today helps to recreate the problems of yesterday, particularly as a critical factor in reproducing women's poverty. 相似文献

The “tragedy of the commons” is the familiar problem that open access to a common property resource leads to overexploitation and to zero profits. A commons model is applied to an example of state sponsored private violence, the practice of privateering or licensed piracy. It is predicted that the presence of uncertainty about the value of the prey will reduce the amount of exploitation effort, and that industry profits may be positive due to both uncertainty and heterogeneous exploiters. Using data from England's wars with France and Spain between 1625 and 1630, the model suggests that the commons, represented by enemy merchant shipping, was not overexploited and that privateering profits were positive. The dynamic paths of privateering effort, ships seized, and individual firm profits were, however, consistent with the normal expectation that commons exploitation will peak and fall, as competition drives down returns through entry. “England was never richer than when at war with Spain.” Sir Edward Coke 相似文献

Measuring School-Related Stressors in Adolescents 总被引:2,自引:0,他引:2
Some 1620 high school students responded to 68 items that measure adolescent stressors. Thirty-five of the items were based on J. P. Kohn and G. H. Frazer's Academic Stress Scale [1(1986) An Academic Stress Scale: Identification and Rated Importance of Academic Stressors, Psychological Reports, Vol. 59, pp. 415–426] developed in the United States, while the remaining 33 items were developed from P. Strutynski's [(1985) A Survey of Queensland Year 10, 11 and 12 Student Attitudes to Schools and Schooling, State Planning Committee, International Youth Year, Brisbane] lists of the most frequently named problems of 2336 Australian high school students. Confirmatory Factor Analysis was used to test and develop a measurement model developed from an extensive review of previous scales. The High School Stressors Scale emerged from the analytic process and measures nine school-related stressors. For researchers focusing on school-related problems and stressors among adolescents, the HSSS promises to be a very useful instrument. It has sound construct and predictive validity and adequate reliability, as demonstrated by the goodness-of-fit indices the squared multiple correlations. 相似文献

The purpose of this study was to examine in a sample of 11,516 secondary school students the extent to which different behavioral, emotional and cognitive problems (a) reflected one or more underlying common factors; (b) actually cooccurred; and (c) were single problems. Principal Component Analyses were performed and percentagewise techniques were used. PCA demonstrated that one or more general syndromes could not by far account for all of the variance of the variables. The results suggest the existence of adolescent subgroups with divergent comorbidity patterns: those who primarily report one single symptom; those who report concurrent symptoms either exclusively in the category of behavioral problems or exclusively in the category of emotional and cognitive problems; and those who report concurrent symptoms in both categories. This distinction between different subgroups has important theoretical, diagnostic, and treatment implications. 相似文献

The author relates three cases of conflict which he has observed in Cairo and recognizes patterns that cut across each of these stories. The stories shed light on how people in Egypt approach and deal with conflict; in addition, they may help readers understand conflict in their home culture as well as be instructive on how to listen to conflict in different cultures. Six general themes in the way Egyptians approach or handle conflict are identified, and each of these themes is analyzed. 相似文献
