Using data from the British Household Panel Survey and the National Survey of Families and Households in the United States, we present a sociodemographic profile of fathers and compare the determinants of absent fatherhood in each country. Although fatherhood has a younger profile in the United States, especially for blacks, predictors of fathers’ residency with their children are remarkably similar in the two countries. In both countries, the strongest predictor of a father’s absence is the parents’ relationship to each other at the time of the child’s birth. Policy implications of this finding are discussed.  相似文献

Messick's (1989) theory of test validity is profoundly influential (Hubley and Zumbo, 1996; Angoff, 1988) in part because it brings together disparate contributions into a unified framework for building validity arguments. At the heart of Messick's theory lies a synthesis of realism and constructivism with respect to both scientific facts and measurement. Within this synthesis there remains a tension between the evidential basis and the consequential basis for test interpretation and use. This cannot be sidestepped simply by limiting the evidential basis to test interpretation and the consequential basis to test use: Interpretation and use are not so easily held separate. The roles of constructivism and context in Messick's theory underline the inherent link between facts and values, but the assumption that facts are objective and values are subjective goes unquestioned in Messick's theory. The inherent link between facts and values combines with this assumption to produce the unresolved tension in Messick's theory. This suggests that a unified theory of test validity requires a theory of value justification.  相似文献

This is a response to Basil Zimmer's contention that the classical hypothesis connecting social mobility with fertility was rejected in the Princeton Fertility Study because of a faulty mode of analysis. Arguing from the findings of a strong association in a sample of Aberdeen women, Zimmer asserts that if social origin and destination were taken into account, the same relationship would have emerged in the U.S. data. The evidence from the Princeton Study is reviewed and new evidence presented which confirms the original findings of no relationship.  相似文献

The study of deprivation, as a social indicator, is basic in the design and development of public policies because it allows decision makers to identify and analyse needy areas in order to improve their citizens’ well-being. The methodological approach proposed for the development of a new deprivation index is based on the Causal Theory whose conceptual model is analysed using Structural Equations. The domains selected for the deprivation index are: education, employment, income, housing, infrastructures and health. A structural equation model based on variance is the exploratory method used to obtain the indices pertaining to the above mentioned areas; the results obtained are seen to be quite reliable. There is a positive connection between the areas of education, employment and income while the relations between infrastructures and health are found to be negative. The results can be projected at a local level and show basic territorial deficiencies. The spatial units studied are the Andalusian (south of Spain) municipalities (770). The spatial projection of the indices obtained for the domains of deprivation highlights the existence of geographical areas which could be a potential target for public action.  相似文献

Regulatory shifts in US border policy set in motion through implementation of the Western Hemisphere Travel Initiative are concurrent with recent formal and functional changes to the US passport. This article examines these modifications interweaving themes of boundary, mobility, and identity. The study focuses on the tripartite means by which the state employs the passport: as the primary affixer of national identity; as a mediator of contact and mobility across national boundaries; and as a mode for the projection of a certain territorial discourse to its citizenry and ‘others.’ These concepts are developed through an analysis of the narrative and iconic representations contained within the new book itself; material sources from government archives; as well as discussions and interviews with US State Department functionaries closely associated with the design and distribution of the new e-passport. Through the latter examination, a view is afforded into the process by which key state documents are crafted and an inherent tension revealed within an agency charged with establishing a particular unifying ‘brand’ for the preeminent instrument of national identification, whilst dutifully acknowledging the diverse constituency of a nation that historically fashions itself as one constructed from the many. In conclusion, the study suggests that the new passport is the handiwork of a plethora of state actors and a servant of many masters, for it is not only a facilitator of mobility and a vouchsafe for the identity of the bearer, but also, a tiny but significant piece of US property, itself an agent of border maintenance and boundary construction that enables the state to lay claim to its citizenry.  相似文献

Connections to the sea often define the character of coastal towns. However, as migrants arrive and economic diversification occurs, views about the use of marine resources and the ocean environment can change. Using survey data from Maine, we examined whether shifting demographics affect public perceptions of marine resource uses and coastal environmental concerns. We tested resource use and environmental items against a common set of demographic, background, and place-related variables. Results indicate that the level of education and the county of residence predict Mainers?? views about different marine resource uses and ocean-related environmental issues. Political party affiliation strongly influences environmental concern but not views about the use of marine resources. Migration history, on the other hand, has little effect. Understanding community contexts as well as individual background and ideological orientations will be critical as managers attempt to balance alternative uses of marine resources and resolve coastal environmental problems.  相似文献

This paper investigates the political framing of population in policy discourse through an analysis of legislative documents. Semantic network analysis was conducted and results were interpreted through discourse analysis of the typical arguments identified. Policy texts were classified into three sets: population management, reproductive health and family planning, and anti-abortion and anti-FP. While the “population management” frame focuses on social and economic consequences of population growth, the “reproductive health” frame defines the problem from a health perspective. Both policies propose aggressive FP programs but each frame uses distinct political rhetoric and semantic approach in its arguments. The “anti-abortion and anti-FP” frame identifies two problems: rise in incidence of abortion and existing policy that prohibit health professionals from refusing patients information on contraception. By invoking a moral argument and anchoring on rights, these policies challenge the problem and solutions identified by the first two frames.  相似文献

In this paper, we investigate differences in academic performance among students of different ages within the same cohorts using a unique database of students at Bocconi University. Our data allow to control for potential selection effects as well as for differences in cognitive ability, as measured by an attitudinal entry test. Contrary to most of the existing evidence for younger pupils, we document that at the undergraduate level, youngest students perform better compared with their oldest peers. This finding is only partly explained by differences in cognitive ability and rather seems to be associated with differences in social activities.  相似文献
