Age and social gradients in the intensity of aging males' symptoms in Poland

Background. We performed the study in order to describe the age-related changes and social gradients in the intensity of aging males' symptoms in healthy men in Poland.

Methods. We examined 405 men aged 32–79, healthy inhabitants of Poland. Severity of aging males' symptoms was assessed using the Polish version of AMS scale. The social position was expressed using their educational level, commonly accepted as a reliable and specific index of social status in Poland.

Results. Male aging in Poland was accompanied by an increase in the intensity of all groups of evaluated symptoms (psychological, sexual and somato-vegetative symptoms, respectively: r = 0.36, r = 0.72, r = 0.59, all p < 0.0001). The results of ANOVA revealed the independent effects of both age and social status on the intensity of psychological symptoms (F = 17.89, p < 0.0001 and F = 9.51, p < 0.0001 for age and educational level, respectively), sexual (F = 114.70, p < 0.0001 and F = 5.90, p < 0.01), and somato-vegetative symptoms (F = 52.86, p < 0.0001 and F = 3.85, p < 0.05). The better the education of Polish men, the less intense the aging males' symptoms, irrespective of their age.

Conclusions. Age and social position constitute major determinants of the intensity of aging males' symptoms in Poland.     

Globalization and the New Spaces for Social Movement Politics: The Marginalization of Labor Unions in Bolivian Gas Nationalization

This article aims for a critical engagement with the new spaces for social movement politics. Recent literature focusing on the relationship between globalization and these spaces foregrounds the new opportunity structures for political practices. Yet amid talk of ‘grassroots globalization’ and ‘globalization from below’, it is important to remain sensitive to how certain forms of practice and organization, particularly those of labor unions, are marginalized within the political spaces of globalization. This paper investigates how the political spaces of globalization shaped the nationalization of gas resources in Bolivia. Nationalization was achieved by new social movements partly negotiating within political spaces opened by globalization. Yet the interests and demands of labor unions were significantly marginalized in implementation. ‘Actually existing’ nationalization can best be described as a pragmatic renegotiation of contracts, in response to a dual pressure from new social movements and from economic globalization. Bolivian nationalization of gas illustrates how union politics around issues of work are constrained within the political spaces of globalization.

Este artículo intenta conseguir un compromiso crítico con los nuevos espacios para la política de movimientos sociales. Una literatura reciente con un enfoque en la relación entre la globalización y estos espacios, destaca las nuevas oportunidades de estructuras para las prácticas políticas. No obstante, al hablar de “la globalización de base popular” y “la globalización desde abajo”, es importante mantenerse sensible ante la manera como ciertas formas de práctica y organización, particularmente aquellas de los sindicatos laborales, se han marginado dentro de los espacios políticos de la globalización. Este trabajo investiga cómo los espacios políticos de la globalización dieron forma a la nacionalización de los recursos de gas en Bolivia. La nacionalización se logró mediante nuevos movimientos sociales, en parte negociando dentro de los espacios políticos abiertos por la globalización. Aún así, en la implementación, los intereses y las demandas de los sindicatos laborales fueron marginadas considerablemente. “De hecho, la nacionalización existente” se puede describir mejor como una renegociación pragmática de contratos, en respuesta a la doble presión de los movimientos sociales y a la globalización económica. La nacionalización boliviana del gas ilustra cómo la política de los sindicatos alrededor de los asuntos de trabajo, están restringidos dentro de los espacios políticos de la globalización.

     

Practice innovations in mental health services to children and families: New directions for Massachusetts∗

This research report highlights selected findings that describe the characteristics of excellent, innovative programs for high‐risk children and adolescents in Massachusetts. The conclusions reported are based on interviews with administrators and providers at nine sites. A research consortium composed of policy makers, administrators, clinicians, and academic researchers recommended the site selections. The study describes a spectrum of innovative practices used to help youngsters in severe crises. Innovative practice was shaped by a common vision of doing treatment within family and community contexts, and coordinating overall care at all levels of the family's social and professional networks. Topics addressed include an examination of the core values directing these programs, the four distinct subtypes of design, therapeutic approaches, management, and evaluation. Obstacles to innovation are considered in light of current policy and practice limitations. The discussion concludes with a summary of the challenges and future directions for policy makers, funding agencies, program directors, and clinicians committed to addressing the current crisis in mental health care for children and youth.     

Performance of some ridge regression estimators for the multinomial logit model

This article considers several estimators for estimating the ridge parameter k for multinomial logit model based on the work of Khalaf and Shukur (2005 Khalaf, G., and G. Shukur. 2005. Choosing ridge parameters for regression problems. Commun. Statist. Theor. Meth., 34:1177–1182.[Taylor &; Francis Online], [Web of Science ®] , [Google Scholar]), Alkhamisi et al. (2006 Alkhamisi, M., G. Khalaf, and G. Shukur. 2006. Some modifications for choosing ridge parameters. Commun. Statist. Theor. Meth. 35:2005–2020.[Taylor &; Francis Online], [Web of Science ®] , [Google Scholar]), and Muniz et al. (2012 Muniz, G., B. M. G. Kibria, K. Månsson, and G. Shukur. 2012. On developing ridge regression parameters: A graphical investigation. in SORT. 36: 115–138.[Web of Science ®] , [Google Scholar]). The mean square error (MSE) is considered as the performance criterion. A simulation study has been conducted to compare the performance of the estimators. Based on the simulation study we found that increasing the correlation between the independent variables and the number of regressors has negative effect on the MSE. However, when the sample size increases the MSE decreases even when the correlation between the independent variables is large. Based on the minimum MSE criterion some useful estimators for estimating the ridge parameter k are recommended for the practitioners.     

Markov chain Monte Carlo with the Integrated Nested Laplace Approximation

The Integrated Nested Laplace Approximation (INLA) has established itself as a widely used method for approximate inference on Bayesian hierarchical models which can be represented as a latent Gaussian model (LGM). INLA is based on producing an accurate approximation to the posterior marginal distributions of the parameters in the model and some other quantities of interest by using repeated approximations to intermediate distributions and integrals that appear in the computation of the posterior marginals. INLA focuses on models whose latent effects are a Gaussian Markov random field. For this reason, we have explored alternative ways of expanding the number of possible models that can be fitted using the INLA methodology. In this paper, we present a novel approach that combines INLA and Markov chain Monte Carlo (MCMC). The aim is to consider a wider range of models that can be fitted with INLA only when some of the parameters of the model have been fixed. We show how new values of these parameters can be drawn from their posterior by using conditional models fitted with INLA and standard MCMC algorithms, such as Metropolis–Hastings. Hence, this will extend the use of INLA to fit models that can be expressed as a conditional LGM. Also, this new approach can be used to build simpler MCMC samplers for complex models as it allows sampling only on a limited number of parameters in the model. We will demonstrate how our approach can extend the class of models that could benefit from INLA, and how the R-INLA package will ease its implementation. We will go through simple examples of this new approach before we discuss more advanced applications with datasets taken from the relevant literature. In particular, INLA within MCMC will be used to fit models with Laplace priors in a Bayesian Lasso model, imputation of missing covariates in linear models, fitting spatial econometrics models with complex nonlinear terms in the linear predictor and classification of data with mixture models. Furthermore, in some of the examples we could exploit INLA within MCMC to make joint inference on an ensemble of model parameters.     

Approaches to sample size calculation for clinical trials in rare diseases

We discuss 3 alternative approaches to sample size calculation: traditional sample size calculation based on power to show a statistically significant effect, sample size calculation based on assurance, and sample size based on a decision‐theoretic approach. These approaches are compared head‐to‐head for clinical trial situations in rare diseases. Specifically, we consider 3 case studies of rare diseases (Lyell disease, adult‐onset Still disease, and cystic fibrosis) with the aim to plan the sample size for an upcoming clinical trial. We outline in detail the reasonable choice of parameters for these approaches for each of the 3 case studies and calculate sample sizes. We stress that the influence of the input parameters needs to be investigated in all approaches and recommend investigating different sample size approaches before deciding finally on the trial size. Highly influencing for the sample size are choice of treatment effect parameter in all approaches and the parameter for the additional cost of the new treatment in the decision‐theoretic approach. These should therefore be discussed extensively.

Well-being and occupational roles among middle-aged women

One purpose of the present study is to explore the stability of the pattern of health/work and sickness absence among middle-aged women over a period of three years. This study tested two hypotheses: (a) that enduringly healthy working women would perceive more valued occupational roles and higher well-being than long-term sick-listed women; (b) that high levels of well-being at baseline would predict enduring health and occupational role value at a 3-year follow-up. Middle-aged women (n = 208) answered a postal survey with the Role checklist, a well-being scale and questions about work and sickness situation. The results showed that there was a considerable variability in the pattern of health/work and sickness absence. The variability was greatest among the women who were long-term sick-listed at baseline, and the internal drop out was great among them. The results showed that the enduringly healthy women experienced a more valued worker role and higher well-being than the long-term sick-listed women. Furthermore, high levels of well-being concerning health and work predicted enduring health in the studied sample, and high well-being concerning work was predictive of a valued worker role. Interventions that enable women to develop valuable worker and leisure roles, as well as harmony between different roles, may be important constituents of health promotion/rehabilitation programmes.     

Expedited permanency planning: evaluation of the Kentucky Adoptions Opportunities Project

This article presents the evaluation findings of a Kentucky Adoptions Opportunities Project (KAOP), a three-year project funded by the U.S. Department of Health and Human Services, Administration on Children, Youth and Families, Children's Bureau. The primary goal of the KAOP was implementation of three permanency planning activities: (1) risk assessment/concurrent planning, (2) one child/one legal voice, and (3) early placement in kinship or foster/adoptive homes. These activities were designed to expedite a permanency placement decision within 12 months for high-risk children. The evaluation of 124 high-risk children in the KAOP revealed that the majority of children had one or both parents coping with multiple risk factors, including mental illness, substance abuse, mental retardation, or family violence. The major barriers to permanency are discussed, as well as the policy and practice implications in the context of Adoption and Safe Families Act of 1997.
