Abstract This research examines differences between those Mexican migrants choosing metropolitan destinations and those choosing destinations outside metropolitan areas of the United States. Using general estimating equations, the study presents data indicating that since the 1960s migrants choosing rural destinations are less fluent in English, slightly older, much less educated, far more likely to be unskilled, more likely to be married, and more likely to be undocumented. The picture is more complex when consideration is restricted to those migrants arriving in rural areas since the passage of the North American Free Trade Agreement. These migrants are far more likely to be single, have more education but have less English fluency, have less work experience, and have less family experience with migration to the United States. They are more likely to come from small towns and rural areas of Mexico.  相似文献

According to standard theory founded on Harsanyi (J Polit Econ 61:434–435, 1953; 63:309–321, 1955) a social welfare function can be appropriately based on the individual’s approach to choice under uncertainty. We investigate how people really do rank distributions in terms of welfare. According to Harsanyi, the evaluation can be done from the standpoint of an uninvolved external judge, a public official, for example, or by a person who knows that she holds one of the positions in society, with an equal chance for any of the available positions. Are these two structures to be viewed differently? We use a questionnaire experiment to focus on the two different interpretations of the Harsanyi approach. There are important, systematic differences that transcend the cultural background of respondents.  相似文献

Analyses of data from the 2000 US Census show that the gender pay gap differs by sector of employment and according to the part of the earnings distribution that is considered. The gender pay differential in the private sector in the US does not display either the glass ceiling or sticky floor effects that have been reported for many other countries. The government sector is, however, characterized by a distinct sticky floor effect in the female–male pay differential. Regardless of the sector of employment, females have lower hourly rates of pay than men across the entire earnings distribution.

School-aged children with an ethnic minority background are relatively often involved in bullying and victimization, but the role of ethnic composition of schools in this context remains unclear. This study examined the relation between ethnic minority background, ethnic school composition, and bullying behaviour around primary school entry in the Netherlands. The study was based on a 2008/2009 school survey in Rotterdam, a Dutch city where about 50 % of children have a non-Dutch background. For 8523 children, teacher reports of bullying behaviour at age 5–6 years were available. Children with a non-Dutch background had higher odds of being a victim (adjusted OR 1.41, 95 % CI 1.11, 1.80), bully (OR 1.38, 95 % CI 1.20, 1.58) or bully-victim (OR 1.38, 95 % CI 1.19, 1.62) than children of Dutch national origin. Ethnic diversity in schools increased children’s risk of bullying behaviour (e.g. ORvictim per 0.1 increase in 0–1 diversity range = 1.06, 95 % CI 1.00, 1.13), with children of both Dutch and non-Dutch national origin relatively more often involved in bullying in ethnically diverse schools. The proportion of same-ethnic peers in school reduced the risk of bullying among children of Dutch national origin (e.g. ORvictim per 10 % more same-ethnic children = 0.90, 95 % CI 0.83, 0.98), but not among non-Dutch children. In conclusion, ethnic minority background and ethnic diversity within schools are risk factors for bullying among 5–6 year olds. Plausibly, reductions in absolute numbers of bullying events may be obtained with tailor-made interventions in ethnically diverse schools. Such interventions should preferably be offered early in the school curriculum.  相似文献

This article reviews the literature on social problems work concerned with children and young people. Social problems work involves assessing particular people, events and circumstances as instances of social problems. We focus on how social problems work is organized within discourses of childhood and youth, how it is a site for holding children and young people accountable, and how normalization is an aspect of social problems work. Our review brings together analytic themes in the literature on social problems and that on children and young people. We also point to topics that might be elaborated upon in future research on social problems work concerned with children and young people.  相似文献

This study replicates a previous finding forthe U.S. counties that showed a strongassociation, net of controls between``structural pluralism' and lower mortality. ``Structural pluralism' refers to a community'scapacity for political competition, and is acore element of ``democracy.' Pluralism hasthis effect because it facilitates theacquisition of appropriate medical facilitiesand because it tends to optimize the biologicalfunctioning of the residents. Working from amajor component of pluralism, minorityparticipation, this hypothesis is tested byshowing that women's status in less developedcountries improves life expectancy net ofcontrols. A path analysis demonstrates thatthe structural dimensions work through healthorganization as an intervening variable, andthe future testing of biological optimizationis outlined. Location in Africa south of theSahara is a partially unexplained controlvariable that has a powerful negative impact. Interpreting women's status as a component ofpluralism explains why it predicts increasedlife expectancy for all citizens, not justwomen. It is a global dimension that affectsall the members of a community.  相似文献

Theory Trimming     
This paper attempts to show that the “Theory Trimming” technique makes little contribution to theory in sociology. A brief history of the technique is given, and several key assertions of its proponents are abstracted. These assertions are shown to be highly questionable. The general alternative to Theory Trimming is shown, and the relationship between Theory Trimming and more general orientations to research is discussed.  相似文献

This paper proposes an interpretation of the pure capital rationing problem as it is faced by many managers in decentralized firms in which budgets serve as the principal means of control. It is argued that the appropriate objective for situations such as these is the maximization of either undiscounted earnings over the planning horizon or total value of the investments at the horizon. When either objective function is used in conjunction with the frequently encountered linear programming models for the capital rationing problem, shadow prices result which give rise to discount rates that will reproduce the optimal solution using discounted cash flow as a criterion. These results are then used as a means for clarifying several confusing and misleading statements that have appeared in the literature.  相似文献
