Evaluation of the mortality impact of nationwide disease-prevention efforts is complicated by potential endogeneity: programme recipients may have unobserved characteristics that simultaneously make them both more likely to become recipients and more likely to survive as a result of other health practices. This population-based study assesses the mortality impact of a nationwide programme that distributed insecticide-treated nets (ITNs) to mothers of children aged 9-59 months in Togo. By comparing mortality rates before and after the programme according to households' eligibility status, we demonstrate that a one-time programme that restricts eligibility to households with a surviving child excludes some households with a high risk of child mortality. We then apply simultaneous estimation models to untangle the mortality impact of ITNs from the effects of unobserved confounders and show that among eligible households, living in a household with ITNs significantly reduces mortality for children aged 20-59 months, even after controlling for endogeneity. 相似文献

Because of the increasing severity of adolescent problem behavior, evidence-based practices are becoming of interest as an alternative to traditional treatment with the behavior problems of adolescents in juvenile justice settings. Despite interest in evidence-based practices, questions exist regarding whether or not evidence-based intervention models can be successfully transported to cultures other than those in which they were developed. This article describes the transportation process of an American evidence-based family therapy (Functional Family Therapy [FFT]) into the service delivery system of a psychiatric day treatment center for juvenile delinquents in Amsterdam. The characteristics of FFT that make it cross-culturally sensitive are discussed. Results from the changes in service delivery suggest FFT can be successfully implemented in international settings with adjustments to make the model fit the culture(s) of The Netherlands without changing the model of FFT itself. 相似文献

The equations of a physical constitutive model for material stress within tantalum grains were solved numerically using a tetrahedrally meshed volume. The resulting output included a scalar vonMises stress for each of the more than 94,000 tetrahedra within the finite element discretization. In this paper, we define an intricate statistical model for the spatial field of vonMises stress which uses the given grain geometry in a fundamental way. Our model relates the three-dimensional field to integrals of latent stochastic processes defined on the vertices of the one- and two-dimensional grain boundaries. An intuitive neighborhood structure of the said boundary nodes suggested the use of a latent Gaussian Markov random field (GMRF). However, despite the potential for computational gains afforded by GMRFs, the integral nature of our model and the sheer number of data points pose substantial challenges for a full Bayesian analysis. To overcome these problems and encourage efficient exploration of the posterior distribution, a number of techniques are now combined: parallel computing, sparse matrix methods, and a modification of a block update strategy within the sampling routine. In addition, we use an auxiliary variables approach to accommodate the presence of outliers in the data. 相似文献

This study provides empirical verification that variations in patterns of coping can explain current and future functioning of youth. The study evaluated the methods and styles of coping of inner–city youth and their relation to age, gender, ethnicity, stress levels, and internalizing and externalizing symptom levels. Three hundred seventy–two 12– to 16–year–old adolescents from inner–city schools (67.0% African American, 24.4% Hispanic; 53.41% males) participated. One hundred forty–nine were also included in a follow–up evaluation of the prospective relation of coping to functioning. A seven–factor model of coping methods was identified and found to be applicable across age groups, genders, and ethnic groups. The model was robust over time. Coping methods were categorized through cluster analysis into five styles. Styles were found to relate somewhat to demographic characteristics and stress levels. Controlling for demographic characteristics and stress levels, coping style related concurrently and prospectively to internalizing and externalizing symptom levels. Except in one instance, age, ethnicity, and gender did not interact with coping in predicting symptoms. Implications for further coping research and risk and intervention design are discussed. 相似文献

ABSTRACTObjectives: Comparing the mean levels of social connectedness and life satisfaction, and analyzing their relationship for 2 undergraduate samples, and testing for an increase in their means for a brief counseling sample. Participants: Between October 2013 and May 2015, 3 samples were collected: not-in-counseling (NIC; n = 941), initial counseling session (ICS; ie, triage session only; n = 168), and brief counseling (BC; ie, median of 4 additional counseling sessions; n = 28). Methods: Online surveys measuring demographic and background control variables, social connectedness, and life satisfaction. Results: NIC students exhibited higher social connectedness and life satisfaction than ICS students. Social connectedness significantly explained life satisfaction beyond controlled-for variables for both samples. There was a significant increase in social connectedness and life satisfaction for the BC sample. Conclusions: Social connectedness is an important antecedent of life satisfaction for undergraduates. Brief counseling can increase transition students' social connectedness and life satisfaction. 相似文献

This article examines the trauma of Sudanese refugee children living in a Midwestern city from a social constructivist view. From a qualitative perspective, the study explored how the Sudanese children, their U.S. foster parents, and social workers from an American child welfare agency described their understanding of the migration experience. Results point to the importance of placing the children's trauma in the context of their own cultures, as child welfare workers assist in the children's adjustment to the United States. 相似文献

Homelessness is one of the most pressing social problems today. The Institute of Medicine defines the problem as a failure in the support systems created to prevent the problem and a tighter housing market. The assumption is that the support system should help to prevent the occurrence of homelessness. The Eastern Fairfield County area performed a study to look at the relationship between those services serving people who are homeless and near homeless to determine the availability, accessibility, and adequacy of services for homeless people. The study identified several barriers in the service delivery system. A strategy was then developed to address these barriers. This paper shows how a research process can facilitate a community response to a social problem. The paper presents the steps that were taken so other communities may replicate the process. 相似文献

Prior qualitative research has indicated that leader performance in complex environments requires active analysis of the key causes operative in the organizational system. To provide some quantitative evidence to bear on this proposition, 160 undergraduates were presented with a computer simulation task that placed the participant in the role of a university president in charge of raising educational quality on campus. Training in the analysis of causes was provided, along with additional manipulations which varied the quality of case readings as well as levels of complexity in the environment. Overall, it was found that training in causal analysis significantly improved leader performance. The implications of these findings for understanding leader performance in complex environments are discussed. 相似文献

Preening or self-grooming among young adults was observed in this study. Two hypotheses were tested. The first was that females would preen more than males. The second was that people in the presence of others with whom they share an established relationship would preen less than those who are developing a relationship. Both hypotheses were confirmed. 相似文献
