This article studies early childhood health in India, Bangladesh, and Nepal, focusing on inequalities in anthropometric outcomes by religious adherence. India and Nepal have Hindu majorities, while Bangladesh is predominantly Muslim. The results suggest that Muslim infants have an advantage over Hindu infants in height‐for‐age in India (for boys and girls) and in Bangladesh (for boys). However, this advantage disappears beyond 12 months of age, at which point Hindu children in all three countries are found to have significantly better anthropometric outcomes than Muslim children. We report tests that rule out mortality selection and undertake falsification and robustness exercises that confirm these findings. Further results suggest that exposure to Ramadan fasting in utero may lead to positive selection of Muslim male infants, partially explaining the Muslim infant health advantage, but this does not fully explain the shift from Muslim advantage in infancy to Hindu advantage in childhood in all three countries.  相似文献

Our study is the first-ever initiative to merge administrative databases in Massachusetts to evaluate an important public mental health program. It examines post-incarceration outcomes of adults with serious mental illness (SMI) enrolled in the Massachusetts Department of Mental Health (DMH) Forensic Transition Team (FTT) program. The program began in 1998 with the goal of transitioning offenders with SMI released from state and local correctional facilities utilizing a core set of transition activities. In this study we evaluate the program's effectiveness using merged administrative data from various state agencies for the years 2007-2011, comparing FTT clients to released prisoners who, despite having serious mental health disorders, did not meet the criterion for DMH services. By systematically describing our original study design and the barriers we encountered, this report will inform future efforts to evaluate public programs using merged administrative databases and electronic health records.  相似文献

The skip-lot sampling plans are widely used in industries for quality inspection of products in order to reduce the sampling costs and inspection efforts when products have good quality history. Also, the skip-lot sampling plan concept is sound and useful and it is economically advantageous to use the skip-lot approach in the design of sampling plans. Thus, the skip-lot sampling plans are useful to minimize the cost of the inspection particularly in costly and destructive testing. Hence, a new system of skip-lot sampling plans designated as SkSP-2-R plan is developed in this article by incorporating the idea of resampling procedure in the skip-lot sampling plans of type SkSP-2. A Markov chain formulation and derivation of performance measures for this new plan are presented. The properties and advantages of the SkSP-2-R plan are studied with single sampling plan as the reference plan. The response-to-change characteristics of the SkSP-2-R plan are also investigated, based on the average run length.  相似文献

We examined whether attachment security moderates influences of two gender identity variables—felt gender typicality and felt pressure for gender differentiation—on preadolescents' well‐being. We tested two hypotheses. The first was that attachment security protects children from the distress that can stem from feeling gender atypical or from feeling pressure for gender conformity. The second was that secure children derive well‐being from believing they are similar to same‐gender peers whereas insecure children derive well‐being from believing it important to be different from other‐gender peers. We assessed children's attachment security, gender identity, and well‐being (self‐esteem, internalizing problems) in two successive years (N = 211, M initial age = 10.1 years). Results supported the second hypothesis. Attachment security may govern children's contingencies of well‐being.  相似文献

Initially drawing from, yet then expanding on the research discussed in this volume, this article discusses specific measures that practitioners, researchers, and policymakers can take to support purpose among youth. Strategies for educators include utilizing practical purpose teaching tools, such as purpose interviews, purpose-related discussions, whole classroom and school community games, and purpose survey methodologies. Research strategies include expanding the study of youth purpose to more diverse groups of young people, and developing more succinct tools to assess purpose in research. Finally, the article discusses policy measures to promote purpose, including modification of current academic testing practices, expanding the breadth of course and extracurricular experiences in schools to provide opportunities for purpose development, and integrating purpose promotion skill-building into existing teacher education programs.  相似文献

We use village census data and linear regression models to examine changes between 1975 and 2002 in the associations of parental resources with boys’ and girls’ schooling in four rural Guatemalan villages. Levels of schooling in 1975 were universally low for children 7–17 years. Large increases in schooling achievements occurred between 1975 and 2002. By 2002, schooling levels were comparable for younger boys and girls (7–12 years, N = 3,525) and favored older boys compared to older girls (13–17 years, N = 2,440) by about 0.5 grades. The associations of household standard of living and maternal schooling with schooling among girls diminished over time and became more comparable with these associations among boys, and the associations of household standard of living with schooling among older boys declined and became more comparable with these associations among girls. Thus, as increased social investments reduce the costs of schooling or increase the supply and quality of schooling to families, the magnitudes of the associations between parental resources and children’s schooling decline and become more gender equitable at all ages. However, our results show that older boys may benefit more than older girls from social investments in schooling. These changes suggest potential needs to monitor gender gaps in schooling retention among older children, to insure gender equitable access to social investments in schooling, and to encourage parents to invest in schooling as joint measures to achieve greater schooling achievements of girls and boys.  相似文献

Let Mo denote the number of empty cells when n balls are dropped independently and at random in m cells such that each ball stays in its cell with probability p and falls through with probability 1-p. A Poisson limit is known for Mo when (n/m)→∞. We find a corresponding approximation to the distribution of Mo when m is large but finite, Ihe method is elementary, and yields the rate of convergence to the limit law. Ihe results are new for the classical case (p = 1) as well.  相似文献

Deriving weights from pairwise comparison matrices (PCM) is a highly researched topic. The analytic hierarchy process (AHP) traditionally uses the eigenvector method for the purpose. Numerous other methods have also been suggested. A distinctive feature of all these methods is that they associate a quantitative meaning to the judgemental information given by the decision-maker. In contrast, the verbal scale used in AHP to capture judgements does not associate such a quantitative meaning. Though this issue of treating judgements qualitatively is recognized in the extant literature on multi-criteria decision making, unfortunately, there is no research effort so far in the AHP literature. Deriving motivation from the application of data envelopment analysis (DEA) for deriving weights, it is proposed in this paper that DEA models developed to deal with a mix of qualitative and quantitative factors can be used to derive weights from PCMs by treating judgements as qualitative factors. The qualitative DEA model is discussed and illustrated in this paper.  相似文献
