Empirical studies in the migration literature have shown that enclaves (networks) negatively affect the language proficiency of migrants. Most of these studies do not address the choice of location as a function of language skills. Using data on Mexican migration to the US, we show that migrants choose smaller networks as their English language proficiency improves.

The relationship between political economy and population economics involves many important issues such as the roles of voters, interest groups, families, and social policy. In this short note, we discuss the new and intriguing issues raised by current research at the intersection of these two subjects.  相似文献

Socializing risks from catastrophic losses is difficult even in an ideal political environment, owing to different estimates of low probability risks, solvency constraints, dangers of moral hazard, and high loss correlation. However, these intrinsic contracting problems do not justify invalidating ordinary insurance contracts or forcing insurers to cover catastrophic losses. Yet, political pressures forcing insurance subsidies now induce inefficient decisions in siting and construction, with high expected social losses. Ordinary contract solutions are always imperfect, but superior to the regulatory maze. Unfortunately, patterns of legislation and court decisions are running in the wrong direction.  相似文献

In recent years, increasing attention has been paid to situational factors associated with childhood sexual abuse (CSA) to explain incidence of CSA, as well as to provide potential targets for prevention efforts. However, very few studies have examined situational factors associated with juvenile perpetration, despite juveniles composing a substantial proportion of offenders. In addition, no studies to our knowledge have applied a situational framework to CSA research in the Orthodox Jewish community (OJC). In the present study, we obtained data from therapists regarding 80 victims of CSA in the OJC from both the United States and Israel. We hypothesized that (a) more abusers’ first perpetration would be between ages 12 and 17 than between any other age range, which corresponds to increased sexual urges, as well as increased unsupervised access to minors; (b) among juvenile offenders, the time of day of the abuse would depend on the relationship of the offender to the victim; and (c) age of the victim and grooming strategies would be associated with the frequency of abuse. Our first two hypotheses were confirmed, and our third hypothesis was partially confirmed, as younger victims tended to have higher frequency of abuse. Additionally, we discuss possible implications of significant correlations found during exploratory analyses. Our results generally support the importance of considering culturally specific situational factors when studying or developing prevention efforts for CSA.  相似文献

While much is known about youth struggles after reintegration into the home and community settings following stays in out‐of‐home care, little is known about appropriate supports for aftercare, or parent (see Note 1 ) and youth perceptions during this critical transition period. This study seeks to begin to address these questions through surveys evaluating youth (n = 48) and parent (n = 48) perceptions of (i) transition planning, family preparedness and aftercare; (ii) youth preparedness for the transition period across major life domains (e.g. education, health care, relationships); and (iii) the importance of specific aftercare supports and services. Results indicate differences between youth and parents on perceptions of need for continued supports, likelihood of participation in aftercare programs; and youth preparedness for success in relationships, family and independent living domains. In contrast, similarities were found on youth and parent ratings regarding the importance of specific services and supports, with both groups indicating supports in education as most important and supports in mental health as least. Study limitations, future research and implications are provided.  相似文献

This paper describes the McMaster Family Assessment Device (FAD), a newly developed questionnaire designed to evaluate families according to the McMaster Model of Family Functioning. The FAD is made up of seven scales which measure Problem Solving, Communication, Roles, Affective Responsiveness, Affective Involvement, Behavior Control and General Functioning. The paper describes the procedures used to develop the FAD and presents scale means and scale reliabilities from a sample of 503 individuals.  相似文献

This paper investigates preference orderings on infinite horizon intergenerational consumption streams. The trade-offs inherent in the selection of moral precepts for an intergenerational preference ordering are made explicit by establishing the mutual inconsistency of an appealing set of axioms.I am grateful to Don Campbell for many valuable discussions and comments. I have also benefitted from the comments of Mike Peters, participants in the Theory Workshop at the University of Toronto, and from a referee and editor of this journal.  相似文献

This article describes the Durham Family Initiative (DFI), an innovative effort to bring together child welfare and juvenile justice systems to reach DFI's goal of reducing the child abuse rate in Durham, North Carolina, by 50% within the next 10 years. DFI will follow principles of a preventive system of care (PSoC), which focuses on nurturing the healthy parent-child relationship. A community collaborative of government agency directors has signed a memorandum of agreement to implement the PSoC principles. The researchers will use multiple methods to evaluate DFI's efficacy.  相似文献

The Doubles, funded by the National Institute on Drug Abuse, is a seven-episode series of media tools designed to teach third and fourth grade students about the science of drug addiction. The program's curriculum is delivered via a set of videos, interactive CD-ROMs, workbooks, or an Internet site. This article examines the process used to develop The Doubles and argues that its success stems from the careful balancing of the needs of the funding agency, state and national curricular guidelines, and the target audience.  相似文献

The why, when, and how of immigration amnesties   总被引:2,自引:1,他引:1  
This paper deals with granting of an amnesty to illegal immigrants. We consider government behavior with respect to allocations on limiting infiltration (border control) and apprehending infiltrators (internal control) and with respect to the granting of amnesties, the timing of amnesties, and limitations on eligibility for those amnesties. We demonstrate the effects of government actions on allocations and the flow of immigrants, and how the interactions between these factors combine to yield an optimal amnesty policy. We also consider two extensions—intertemporal transfers of policing funds and “fuzziness” in declarations regarding eligibility for an amnesty aimed at apprehending and deporting undesirables.  相似文献
