ABSTRACT

This study compared exits between citizen and noncitizen heads of household from the Temporary Assistance to Needy Families (TANF) program. With longitudinal monthly administrative data and a Cox proportional hazard model, the study examined how the economy and recipients’ personal characteristics affected their exits. The sample consisted of 28,308 families headed by citizens and 2,547 families headed by a noncitizen on TANF. Key findings reveal that families on TANF exit the rolls primarily during the first 8 months after entrance. Results showed that families headed by a noncitizen remain on TANF longer than families headed by a citizen. The roles of minimum wage and unemployment in shaping the risk of exit for noncitizen compared to citizen families were explored. Suggestions for further research and how to serve recipients best in times of economic downturns are provided. Similar research needs to be conducted in states where temporary TANF time limits do not exist.  相似文献

Since the social and personal implications of excessive gambling are important, it becomes necessary to assess the extent of the problem within the population. Accordingly, the use of an instrument that evaluates gamblers accurately is essential. This study, carried out with 200 adults, investigates the potential differences in classification of gamblers when using the NORC DSM-IV Screen for gambling problems (NODS) versus a clinical interview. The results show that 50 of the 200 participants were not categorised in the same way with the NODS as with the clinical interview; 47 participants were identified as having a more severe gambling problem according to the NODS than with the clinical interview, providing a 23.5% difference in the concordance rate. This result is discussed in terms of measurement problems in assessing gambling behaviours.  相似文献

ABSTRACT

The tragedy of 9/11 had more far-reaching social and economic consequences for the nation than those found for many individuals on that day. Between October 2001 and May 2002, Nevada witnessed a 25% increase in the total number of households on the Temporary Assistance for Needy Families (TANF) program, commonly referred to as welfare. During the same time, households headed by a noncitizen increased their participation in the TANF program by 40%. This study examines the differential impact of 9/11, as well as of the economy and other external developments, on noncitizen and citizen welfare caseloads in a single state. Two monthly time series models are specified that explain and compare trends in the noncitizen and citizen welfare caseloads from April 1998 to June 2002. The findings suggest that, all else constant, 9/11 had a differential impact on the noncitizen and the citizen caseloads. All else constant, 9/11 events increased the noncitizen welfare caseload whereas a similar impact for the citizen caseload was not found. The findings also strongly suggest that the business cycle shapes noncitizens' participation in public assistance programs more closely than citizens' participation. Future research should investigate the extent to which 9/11 affected the behaviors of families on welfare over the long run.  相似文献

This paper merges data from the Multinational Time Use Study (MTUS) with national parental leave characteristics from eight industrialized countries from 1971 to 2005 to estimate the association between national parental leave arrangements and paternal childcare. We also test whether this association varies according to a father’s educational level. We find that the number of parental leave weeks available to fathers and high rates of benefit are positively associated with fathers’ childcare time. This is generally robust when taking into account country and year as fixed effects, and other country-specific variables such as female employment rates. The magnitudes of the coefficients are economically significant. For example, high parental leave benefits compared to none are associated with an increase of almost 1 h per week in paternal childcare time. This relationship between benefit rate and time spent on childcare is strongest for highly educated fathers. They also benefit the most from exclusive ‘daddy weeks’ whereas the positive association of transferable leave to paternal childcare is solely driven by lowly educated fathers.  相似文献

L'accès aux universités prestigieuses, les mieux classées et dotées de ressources, quoique peu étudié, représente une dimension additionnelle des inégalités en éducation au Canada. La théorie de l'inégalité maintenue efficacement (IME) soutient que les groupes favorisés vont dominer l'accès aux institutions les mieux classées peu importe le palier scolaire. Cet article teste cette hypothèse en utilisant les données uniques de milliers d’élèves du Conseil Scolaire Public de Toronto (TDSB) qui ont été suivis à partir de la neuvième année jusqu’à leur entrée dans un établissement postsecondaire. Ces données ont ensuite été associées aux données de classement des universités, de leur revenu, de leurs dépenses et de leurs fonds de dotation. Une série de modèles statistiques à niveaux multiples indique que l'entrée dans la hiérarchie universitaire ontarienne tend à refléter les inégalités dans l'accès général aux universités. Les femmes, les étudiants d'origine asiatique, et les étudiants issus des quartiers ayant des statuts socio‐économiques élevés sont plus susceptibles d'entrer dans les universités les mieux classées et dotées de ressources; tandis que les étudiants qui s'identifient comme Noirs et hommes, sont moins susceptibles d'entrer dans ces institutions. Les avantages du statut socio‐économique élevé et de l'origine asiatique sont seulement partiellement expliqués par les variables académiques comme variables médiatrices. Ceci suggère que le statut culturel joue un rôle dans l’élaboration du choix universitaire, alors que le sexe ainsi que les autres inégalités raciales sont dus en grande partie aux processus du parcours académique. Access to highly ranked, prestigious, and well‐resourced universities represents an additional yet understudied dimension of educational inequality in Canada. The theory of effectively maintained inequality contends that advantaged groups will dominate access to the best‐positioned institutions within any credential tier. This paper tests this hypothesis using unique data on thousands of Toronto District School Board students that were tracked from Grade 9 to their entry in Ontario postsecondary institutions, and then linked to data on university rankings, incomes, expenditures, and endowments. A series of multilevel models shows that entry into Ontario's university hierarchy tends to mirror inequalities in general access to universities. Female, Asian‐origin, and students from higher socioeconomic neighborhoods are more likely to enter higher ranked and better resourced institutions, while students who self‐identify as black and male are less likely to enter such institutions. High socioeconomic status and Asian‐origin advantages are mediated only partly by academic variables, suggesting that status cultures play a role in shaping their university choices, while gender and other racial inequalities emerge largely through academic processes.  相似文献

Confidence intervals provide a way to determine plausible values for a population parameter. They are omnipresent in research articles involving statistical analyses. Appropriately, a key statistical literacy learning objective is the ability to interpret and understand confidence intervals in a wide range of settings. As instructors, we devote a considerable amount of time and effort to ensure that students master this topic in introductory courses and beyond. Yet, studies continue to find that confidence intervals are commonly misinterpreted and that even experts have trouble calibrating their individual confidence levels. In this article, we present a 10-min trivia game-based activity that addresses these misconceptions by exposing students to confidence intervals from a personal perspective. We describe how the activity can be integrated into a statistics course as a one-time activity or with repetition at intervals throughout a course, discuss results of using the activity in class, and present possible extensions. Supplementary materials for this article are available online.  相似文献

The child welfare system is responsible for identifying long-term caregivers for children whose biological parents are unable or unwilling to care for them. Although grandparents are increasingly identified as custodians for their grandchildren, little is known about how grandparents are assessed by state actors. Using ethnographic data, this article unpacks the failure of one 63-year-old African American grandfather and his wife to gain custody of his grandson from foster care. This case–known informally as ‘the pimp case’ because of the unverified but widely accepted belief that he had earned income through sexual solicitation–illustrates how men's aging bodies and histories undermine their efforts to be seen as competent caregivers. This article shows how this grandfather's aging body and its perceived limitations became problematic, how his illegitimate social history was at issue, how their family form as grandparents (and thus, non-parents) was deemed illegitimate, and how these came together to mark race, class, and gender in interrelated–but also contradictory–ways.  相似文献

The main research question of this article was whether and how predictors of fathers’ participation in childcare, defined as zero versus more than zero minutes of childcare, differed from predictors of participating fathers’ amount of time on childcare, measured as minutes on the survey day. The sample was drawn from the Multinational Time Use Study (MTUS) and covered surveys from ten industrialised countries from 1987 to 2005. Results showed that there were some similarities, but also remarkable differences between factors influencing participation in childcare and factors affecting participating fathers’ time spent with children. Thus they call for caution regarding findings from existing studies not distinguishing participation from participating fathers’ childcare minutes.  相似文献

We describe and analyze a longitudinal diffusion tensor imaging (DTI) study relating changes in the microstructure of intracranial white matter tracts to cognitive disability in multiple sclerosis patients. In this application the scalar outcome and the functional exposure are measured longitudinally. This data structure is new and raises challenges that cannot be addressed with current methods and software. To analyze the data, we introduce a penalized functional regression model and inferential tools designed specifically for these emerging types of data. Our proposed model extends the Generalized Linear Mixed Model by adding functional predictors; this method is computationally feasible and is applicable when the functional predictors are measured densely, sparsely or with error. An online appendix compares two implementations, one likelihood-based and the other Bayesian, and provides the software used in simulations; the likelihood-based implementation is included as the lpfr() function in the R package refund available on CRAN.  相似文献

This article explores shifts that have taken place in British television and British forms of feminine-gendered fiction from the late 1990s. These shifts will be discussed with reference to discourses of the “feminization of television” circulating in British culture during this period. This article contests the suggestion that discourses of the “feminization of television” and texts such as the female ensemble drama produced in this postfeminist period represent unproblematic “narratives of progress” for women (Georgina Harris 2006, Beyond Representation: Television Drama and the Politics of Identity, Manchester University Press, Manchester, p. 1). Rather, this article will suggest that accounts of the “feminization of television” found in the popular press along with contemporary examples of the female ensemble drama re-traditionalize women in relation to the spaces and discourses associated with twentieth-century femininity.  相似文献
