EXAMINING THE WAGE DIFFERENTIAL FOR MARRIED AND COHABITING MEN 总被引:3,自引:0,他引:3
Leslie S. Stratton 《Economic inquiry》2002,40(2):199-212
Wage analyses indicate that married and cohabiting men earn more than do single, noncohabiting men. This article examines the nature of these wage differentials using data from the National Survey of Families and Households. Results indicate that the marital and cohabitation differentials are quite distinct. The higher wage observed for cohabiting men is driven primarily by selection and is eliminated by first differencing, but the higher wage observed for married men (and perhaps long-term cohabiters) arises largely because of differential wage growth. Wages appear to rise more rapidly following marriage. 相似文献

A review of the US ‘program evaluation standards’ (PES), undertaken in a series of workshops and meetings of networks of evaluators in Africa, resulted in modifications to those standards. The result was presented to a plenary session of the Inaugural Conference of the African Evaluation Association in September 1999, attended by over 300 evaluators from 35 countries. The AfrEA Conference decided that a systematic effort should be made to produce a list of African evaluation guidelines, similar to the PES, and that this checklist should be reviewed by national evaluation associations and networks in Africa and field tested in several countries. Ten national and regional networks and associations suggested modifications to the text and endorsed the final version of the guidelines. 相似文献

In this article I deal with transnational Hindu and Muslim movements. I reject the common assertion that migrant communities are conservative in religious and social matters by arguing that ‘traditionalism’ requires considerable ideological creativity and that this significantly transforms previous practices and discourses. I suggest that religious movements, active among migrants, develop cosmopolitan projects that can be viewed as alternatives to the cosmopolitanism of the European Enlightenment. This raises a number of challenges concerning citizenship, integration and political loyalty for governmentality in the nation‐states in which these cosmopolitan projects are carried out. I suggest that rather than looking at religious migrants as at best conservative and at worst terrorist one should perhaps pay some attention to the creative moments in human responses to new challenges and new environments. 相似文献

Over the years, noteworthy social workers have been interviewed for the Clinical Social Work Journal. This article features an interview with Joyce Edward who is recognized for her many extraordinary contributions to clinical social work. Joyce has co-written or co-edited three exceptional books for the social work clinician, she has been an esteemed teacher and a vocal activist for quality mental health care. In this interview Joyce reflects on family influences, her work as a social caseworker, the psychoanalytic luminaries with whom she trained, her concerns about the clinical education of today's social work students, and finally, her perspective on managed mental health care. 相似文献

We examine the impact of communication technology on scholarly productivity by considering patterns of coauthored economics articles. Using articles in three major economics journals from 1970–79 and 1992–96, we find (1) sharp growth from distant coauthorships (authors not in the same metropolitan area prior to publication), as the theory predicts, and, contrary to theory, (2) lower productivity of distant than close-coauthored works and no decline in their relative disadvantage. These findings are reconciled by noting that high technology has aspects of a consumer good. The relative productivity of solo-authored articles has decreased, perhaps explaining the secular increase in coauthorship. 相似文献

Can universities be agents of progressive social change? How would we know if a university was acting as an agent of social change? Drawing on four case studies, I raise a number of questions to problematize our understanding of the university as an agent of social change. I outline a number of contributing factors that appear to explain successful cases. I conclude by arguing the relevancy of these cases for larger, and more traditional, sociological projects. 相似文献

Ninna Nyberg–Sørensen Nicholas Van Hear & Poul Engberg–Pedersen 《International migration (Geneva, Switzerland)》2002,40(5):3-47
In September 2001, the Danish Ministry of Foreign Affairs commissioned a study of the present and potential links between migration and development. In January 2002, the new Danish Government announced a decision to enhance the links between its aid and refugee policies as part of the overall focus on poverty reduction. The present paper provides a state–of–the–art overview of current thinking and available evidence on the migration–development nexus, including the role of aid in migrant–producing areas. It offers evidence and conclusions around the following four critical issues: Poverty and migration People in developing countries require resources and connections to engage in international migration. There is no direct link between poverty, economic development, population growth, and social and political change on the one hand, and international migration on the other. Poverty reduction is not in itself a migration–reducing strategy. Conflicts, refugees, and migration Violent conflicts produce displaced persons, migrants, and refugees. People on the move may contribute both to conflict prevention and reconciliation, and to sustained conflicts. Most refugees do not have the resources to move beyond neighbouring areas, that is, they remain internally displaced or move across borders to first countries of asylum within their region. Aid to developing countries receiving large inflows of refugees is poverty–oriented to the extent that these are poor countries, but it is uncertain what effect such aid has in terms of reducing the number of people seeking asylum in developed countries. Furthermore, such aid may attract refugees from adjacent countries experiencing war or political turmoil. Migrants as a development resource International liberalization has gone far with respect to capital, goods and services, but not to labour. International political–economic regimes provide neither space nor initiatives for negotiations on labour mobility and the flow of remittances. There is a pressing need to reinforce the image of migrants as a development resource. Remittances are double the size of aid and target the poor at least as well; migrant diasporas are engaged in transnational practices with direct effects on aid and development; developed countries recognize their dependence on immigrant labour; and policies on development aid, humanitarian relief, migration, and refugee protection are internally inconsistent and occasionally contradictory. Aid and migration Aid policies face a critical challenge to balance a focus on poverty reduction with mitigating the conditions that produce refugees, while also interacting constructively with migrant diasporas and their transnational practices. The current emphasis on aid selectivity tends to allocate development aid to the well performing countries, and humanitarian assistance to the crisis countries and trouble spots. However, development aid is more effective than humanitarian assistance in preventing violent conflicts, promoting reconciliation and democratization, and encouraging poverty–reducing development investments by migrant diasporas. The paper is a synthesis of current knowledge of migration–development dynamics, including an assessment of the intended and unintended consequences of development and humanitarian policy interventions. We examine whether recent developments in the sphere of international migration provide evidence of a “crisis”, as well as the connections between migration, globalization, and the changing nature of conflicts. We summarize current thinking on the main issues at stake and examine available evidence on the relations between migration and development. Then the consequent challenges to the aid community, including the current debates about coherence and selectivity in aid and relief are discussed and, finally, we elaborate on the four conclusions of the overview. 相似文献

Fire and restoration of the largest urban forest of the world in Rio de Janeiro City,Brazil 总被引:1,自引:1,他引:0
National Park of Tijuca in Rio de Janeiro (Brazil) is about 3,300 ha and considered the largest urban forest in the world. Its floristic composition is typical of Atlantic Rain Forest. The reserve is being altered because of fire occurrences and urban expansion. This study identified locations and causes of forest fires, and makes management recommendations to restore damaged areas. From 1991 to 2000, forest firefighters recorded an average of 75-fire occurrences/year. Identified causes included hot air balloons (24%), intentional (24%), rubbish burning (21%) and religious practices (17%). Primary fuels included invasive grasses and ferns. Although hot air balloons destroyed larger areas of forest in each occurrence, a greater number of fires started in the invasive vegetation along roads that bisect the forest. In response to recurrent forests, invasive vegetation has spread gradually into the forest increasing forest degradation. To decrease fire damage, sites with high fire frequencies and density of invasive vegetation were planted with less flammable species. Results indicate that fire frequency decreased and density of invasive vegetation declined. This approach appears to prevent fire incidence, reduce the need for fire fighting, and preserve existing biodiversity. 相似文献

This paper describes the design optimization of a robot sensor used for locating 3-D objects employing the Taguchi method in a computer simulation scenario. The location information from the sensor is to be utilized to control the movements of an industrial robot in a 'pick-and-place' or assembly operation. The Taguchi method, which is based on the Analysis-of-Variance (ANOVA) approach, is utilized to improve the performance of the sensor over a wider operating range. A review of the Taguchi method is presented along with step-by-step implementation details to identify and optimize the design parameters of the sensor. The method allows us to gauge the impact of various interactions present in the sensor system exclusively and permits us to single out those factors that have a dominant influence on the overall performance of the sensor. The investigation suggests that the Taguchi method is a more structured and efficient approach for achieving a robust design compared with the classical full factorial design approach. 相似文献
