Doreen Massey     
The growth of transnational communications, most notably the Internet and email, has had a profound impact on social and political interactions across borders. Doreen Massey, a social and political geographer, has written widely about space, with an emphasis on examining relations between actors, rather than the roles that they play. Her research suggests that space can be conceived of as constructed of these relations and, as a consequence, power can be seen to operate at multiple and complex levels. This article examines Massey's work, identifying areas of particular relevance to communications scholars. Massey's thinking is applied to the contemporary communications arena, where her ideas on space and 'power-geometries' offer new insights into how the complexities of transnational relations can be understood.  相似文献

Using a resiliency framework, we examined familial and extrafamilial factors associated with adolescent well‐being in intact, blended, and divorced single‐parent families. Hierarchical regression analyses were conducted using a large sample of 7th‐, 9th‐, and 11th‐grade adolescents (N= 2,011) to test the moderating effect of peer support, school attachment, and neighbor support when parental support and monitoring were low. Significant two‐ and three‐way interactions were probed. Findings indicate that divorced and blended families have some of the same forms of resiliency as intact families. For adolescents in a divorced single‐parent family, peer support moderated the effect of low parental support on internalizing symptoms. We discuss the merits of examining divorce from a resiliency perspective.  相似文献

Over the last few decades in the United States, the poverty rate for female-headed families has been about five times the poverty rate for other family types. This paper addresses the question of why, in general, female-headed families are so much poorer than other families. Recognizing that individuals choose their own marital status, a self-selection model is used to identify the factors which determine the poverty rates for married-couple families, families headed by females with no husband present, and families headed by males with no wife present. The following control variables are found to be important determinants of poverty for all three family types: education of family members; age, race, disability, and unemployment of the family head; geographical location, size and composition of the family. Both married-couple families and male-headed families are found to be less poor than female-headed families mainly because the marginal effects of the control variables, and to a lesser extent the mean levels of the control variables, favor the former two types of families over female-headed families.  相似文献

An online survey was administered to 209 junior and senior public relations majors at nine U.S. universities. Students affirmed skills and understandings identified in previous studies as important to the practice of public relations. When asked about their preparedness in the same areas, their responses differed significantly suggesting at least some feelings of lack of preparation for professional practice in some areas. Pedagogical implications, including an increased emphasis on business concepts and crisis planning, are discussed.  相似文献

During October and November 1982, 1,260 Medicare-eligible senior citizens were interviewed in a survey focusing on health care of the elderly. As part of the survey, an experiment was conducted in each of the three survey sites to determine the effects of an advance telephone call to schedule an appointment for a personal interview. One random half sample in each site was sent a lead letter, followed by a telephone call to schedule a personal interview. The other half sample was sent a lead letter followed by a personal contact, with no intervening telephone call. Telephoning to arrange an appointment for a personal interview resulted in a 20 percent saving in data collection costs with only a 1 percent decrease in response rate.  相似文献

The results of an immigrant student census in a California port-of-entry school district are used to describe the educational backgrounds of Mexican immigrant students and to distinguish types of Mexican immigrant students by school entry patterns. Interviews with recently arrived Mexican immigrant parents reveal the educational and occupational expectations they hold for their children in the US. The study findings are used as a basis for raising policy questions and generating research issues. The most notable observation from the study is that the children of Mexican immigrants in La Entrada do not migrate once they are in school. Parents may be migrating back and forth between the US and Mexico, but children once in La Entrada do not leave the school to return to school in Mexico. The study suggests that the parents of immigrant students do not know how the US educational system works but they are interested in helping teachers educate their children.  相似文献

Changing patterns of first marriage in the United States   总被引:1,自引:0,他引:1  
In this paper, we have traced changes in the patterns of first marriage in the United States for cohorts of men and women born in 1880 through 1965 and for the years from 1900 through 1983. There were striking changes in marriage rates associated with each of the world wars and with the depression of the 1930s. In addition to these short-term fluctuations, a long-term shift in marriage rates is observed over the period from after World War II until about 1970. By the end of the 1970s, however, marriage rates had returned to levels similar to those observed before the war. The basic similarity in the timing of changes in marriage rates across age levels and for both men and women, blacks and whites, is a striking characteristic of these marriage curves. There are also, however, important differences among these groups with respect to the magnitude and slopes of the shifts. The postwar marriage boom was strongest among the young (those under age 24) and among whites. Similarly, the declines in marriage rates observed in the 1970s were greatest among the young. The marriage rates for teenagers display trends that diverge in many respects from those of older persons. For example, the marriage rates of male teenagers did not show the "peaks" and "valley" associated with World War II for older age groups and female teenagers. Moreover, there is little sign of the postwar marriage boom among black teenagers of either sex. Indeed, the marriage rates of black teenagers began to decline soon after the war, and by the 1970s the marriage rates of both male and female black teenagers had fallen below those of their white counterparts, reversing the pattern that had existed through the first half of this century. During the twenty-five or so years of the postwar marriage boom, which we believe can be characterized best as a period phenomenon, there were trends-eddies within the mainstream-which are probably most easily interpreted as the consequence of a cohort effect.(ABSTRACT TRUNCATED AT 400 WORDS)  相似文献

The BACHUE model, a dynamic simulation technique developed within the International Labour Organization's World Employment Program, has been applied to the Philippines. The model simulates behavior and consequences in a number of key areas: fertility, marriage, migration, savings and expenditure, and labor force participation for households and a macro-model for demand, ouput, employment, and income. The design and development of the model are discussed in detail. The model was run for a series of 13 experiments ranging from nationlization of modern sectors, increasing self-employment, movement toward labor-intensive techniques, changes in growth rates of various sectors, and a reduction in fertility by 2% over 1976-1985, an increase over the 1% assumed in the base run. Runs R-2 to R-11 all showed that a change in basic needs is associated with significant declines in fertility, largely because of increasing education and decreasing mortality. Better economic conditions in rural areas also reduced migration. R-13 which examined the effects of a family planning program of moderate size on ultimate fertility, showed that even by year 2000 the effects were small. The population is reduced 5% over the run which assumes negative income tax and government subsidies to poor families but the gain in income per adult is less than 4%. Any real improvement in income as the result of family planning will take 40-50 years to achieve. Economic incentives, on the other hand, have much faster demographic results. The models also show that rural-urban migration is responsive to policy changes. Planners are cautioned that the model is not a picture of the entire range of human behavior but is an adjunct for use in analyzing interaction between policies.  相似文献

In this discussion of population growth, inequality, and poverty, the type of relationships that can be observed in intercountry comparisons are explored, reviewing the findings of several other authors, presenting some new estimates using an International Labor Office data bank, considering some basic conceptual problems, and examining some of the theoretical and empirical issues that call for investigation at the national level. Intercountry comparisons, despite their limitations, appear to be the easiest starting point for empirical analysis. The approach adopted by most researchers has been to select 1 or more population indicators and a measure of national income inequality and to explain intercountry differences in 1 or both of these variables in terms of each other and of other indicators of economic and social development. Underlying this methodology is the assumption that there are aspects of demographic and economic change that are common to all countries included in the study, so that differences between countries give some guide to the likely evolution over time within any 1 country. This can be accepted at best with reservations, but given the scarcity of data on the evolution of inequality over time, a working hypothesis of this type appears unavoidable. But, as many of the factors likely to cause population growth and inequality operate over extended periods of time, a dynamic model is indicated. A simpler model, which pays particular attention to lags and variations over time, may generate new insights. A summary of the results of a new international cross-section analysis set up on these lines is presented. Results suggest that contrary to expectations, reducing population growth does not seem to generate longterm benefits for the poor in this model, though some short term gains are found. Increasing equality does appear to generate some decline in population growth, as well as persistent gains in incomes among the poor, but the reductions in population growth look small when set against the substantial reduction in inequality assumed. The central problem is that inequality and poverty are complex variables conceptually and empirically. 3 major sets of issues are particularly relevant: the nature of the unit of analysis; the reference period; and the conceptualization and measurement of welfare in relation to inequality and demographic change. In interpreting empirical findings, it is necessary to be aware of the different aspects of inequality and the correspondingly varied links with demographic change. The issues raised by the effects of inequality on population growth are distinct from those of population growth on the generation of inequality, and these are separated. Future research possibly will be most productive if it concentrates on the multiple roles of population growth in the transformation of systems of production.  相似文献
