The author reviews some of the literature on the Mexican Revolution in order to assess the impact of demographic change on the outcome of that conflict. Consideration is given to urbanization, spatial distribution, literacy, industrial growth and the employment opportunities it provided, and land conflicts caused by population growth.

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 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
