Continuity of treatment and the County Department of Social Services.

Restructuring of the service delivery system in county departments of social services is proposed to accommodate the changes that followed separation of those services and public assistance.     

School Context and the Effect of ESL Placement on Mexican‐Origin Adolescents' Achievement*

Objectives. Immigrant adolescents' academic achievement is crucial to our future economic stability, and Mexican‐origin linguistic minority youth in U.S. schools generally demonstrate lower levels of achievement. English as a Second Language (ESL) programs provide an institutional response to these students' needs, the effect of which may vary by the proportion of immigrant students in the school. Measures. Using propensity score matching and data from the Adolescent Health and Academic Achievement Study (AHAA) and the National Longitudinal Study of Adolescent Health (Add Health), we estimate the effect of ESL placement on Mexican‐origin achievement for first‐, second‐, and third‐generation adolescents separately in schools with many and few immigrant students. Results. The estimated effect of ESL placement varies by both immigrant concentration in the school and by students' generational status. Conclusions. We find that ESL enrollment may be protective for second‐generation Mexican‐origin adolescents in high immigrant concentration schools, and may prove detrimental for first‐generation adolescents in contexts with few other immigrant students.     

Attitudes Toward the Poor and Attributions for Poverty

Prior psychological research on attitudes toward the poor has focused almost exclusively on the attributions people make to explain why individuals are poor (e.g., Smith & Stone, 1989; Zucker & Weiner, 1993). The goal of the current study was to investigate the relationships among feelings about the poor and poverty, stereotypes of the poor, attributions for poverty, and sociopolitical ideologies (as assessed by the Protestant Ethic, Belief in a Just World, and Right Wing Authoritarianism Scales). In our Midwestern college sample (n = 209), attitudes toward the poor were found to be significantly more negative than attitudes toward the middle class. In addition, participants were most likely to blame poor people them-selves for their poverty. However, attitudes toward the poor and attributions for the causes of poverty were found to vary among individuals from different sociodemographic backgrounds and by degree of endorsement of Protestant ethic, just world, and authoritarianism beliefs. Few gender differences were obtained.     

Bayesian sequential inference for nonlinear multivariate diffusions

In this paper, we adapt recently developed simulation-based sequential algorithms to the problem concerning the Bayesian analysis of discretely observed diffusion processes. The estimation framework involves the introduction of m−1 latent data points between every pair of observations. Sequential MCMC methods are then used to sample the posterior distribution of the latent data and the model parameters on-line. The method is applied to the estimation of parameters in a simple stochastic volatility model (SV) of the U.S. short-term interest rate. We also provide a simulation study to validate our method, using synthetic data generated by the SV model with parameters calibrated to match weekly observations of the U.S. short-term interest rate.     

Conditional simulation from highly structured Gaussian systems, with application to blocking-MCMC for the Bayesian analysis of very large linear models

This paper examines strategies for simulating exactly from large Gaussian linear models conditional on some Gaussian observations. Local computation strategies based on the conditional independence structure of the model are developed in order to reduce costs associated with storage and computation. Application of these algorithms to simulation from nested hierarchical linear models is considered, and the construction of efficient MCMC schemes for Bayesian inference in high-dimensional linear models is outlined.     

Do antidepressants work? Statistical significance versus clinical benefits

Ours has been called the Prozac generation but, earlier this year, newspaper front page headlines screamed "Antidepressants don't work". Our authors' reanalysis of drug trials was widely reported as implying that antidepressant drugs such as Prozac are overprescribed and useless. The truth, as Blair T. Johnson and Irving Kirsch explain, is more complex, and more interesting.     

Akathisia. When treatment creates a problem

1. Akathisia is a state of restlessness and motor agitation, which includes subjective feelings of inner tension, emotional unease, anxiety, a constant need to move, restless motor activity, and an inability to tolerate inactivity or rest. 2. Akathisia is often unrecognized or misdiagnosed as agitation or anxiety of psychiatric origin; this often leads to inappropriate increases in the antipsychotic dosage, which then potentiates its severity, or to the misuse of antianxiety agents, which masks symptoms. 3. Akathisia can be easy to recognize by simple clinical observation of the patient's behaviors, especially if the symptoms worsen after increases in antipsychotic dosages or the frequent use of as needed medications. Assessment must also include the patient's own report.     

Acomparison between Northern and Southern blacks residing in the North

Differences between Southern and non-Southern blacks living in the North and West are considered for a wide variety of attributes such as employment, occupation, income, marital stability, and offspring's performance in school. Migrant blacks have generally more favorable rates than their Northern- and Western-born compatriots after standard domographic controls are applied to an unusually detailed set of cross-tabulations based on the One-Percent Sample Tapes for 1960. Perhaps the sharpest gap exists with respect to marital conditions; Southern blacks of both sexes are more likely to marry and, among those ever married, live more frequently with their spouses. Some of the results reported by earlier investigators require considerable modification; For example, the fact that Northern black men are less often at work than migrants has led to speculations about regional differences in work orientation among blacks, but a detailed analysis of labor force activity indicates this pattern does not hold for women. Likewise, the migrant income advantage is found to vary by education such that it is confined to those with low educational attainment. The use of sample tapes permits a novel analysis of differences between Northern-born blacks classified by whether they are second or at least third generation residents of the North (children of Southern- or Northern-born parents, respectively). For the attribute measured, school performance, the gap is essentially nil. Finally, an alternative is suggested to the existing causal interpretations of North-South gaps among black residents of the North. Reconsidered in particular are the higher labor force rates of migrant men and their more frequent employment in blue collar jobs;     

Past Activeness,Solidarity, and Local Development Efforts1

Abstract Actions by local groups and leaders constitute an essential but poorly understood element of many rural development strategies. Previous studies suggest that local development efforts can influence community change, but questions remain about why localities differ in mobilization to achieve development goals. Drawing upon community field theory and human ecology, this study uses data for rural school districts in Pennsylvania to examine the argument that activeness in the past and development of solidarity can contribute to a higher probability of local mobilization than would be predicted by ecological characteristics alone. Hierarchical regressions support this argument for some local actions, while canonical correlations show a generalized pattern strongly associated with past activeness and solidarity.     

‘It's About People and Their Environment’: Student Social Workers' Definitions of Social Work Research

This article considers constructions of social work research from the perspectives of student social workers in New Zealand. There have been many academic discussions of the unique epistemology that can be called social work research but little is known of students and/or practitioner views. Are they interested in social work research? Do they even care about debates on epistemology? Forty-three student social workers considered two questions while attending a social work research methods course: ‘What is social work research?’ and ‘What kind of social work researcher might I be?’. A subset of 18 distance students explored a third question: ‘Should social work research be part of everyday practice or not?’. To answer these questions students provided comments in a short survey, material from their written student assignments and comments from online discussion board activities. The results suggest that student social workers have a preference for social work research that is compatible with their clearly articulated social work value base, and that social work research primarily should benefit the client group with which a social worker is closely linked. Student social workers also recognise the importance of research for their everyday practice, yet at the same time feel there are organisational constraints to this happening.
