Resumen

Hemos realizado un estudio diferencial sobre las interpretaciones causales y sus consecuencias cognitivo- afectivas en un contexto de robo, utilizando como marco teórico el último modelo atribucional de Weiner (1986). Para ello, hemos aplicado cuestionarios de autoinforme a 1.450 sujetos menores de edad. Los resultados, obtenidos mediante análisis de la varianza y técnicas de regresión, indican (1) que existe una taxonomía de las causas claramente diferenciada en función de las dimensiones—locus, estabilidad y controlabilidad—, y de la perspectiva—actor/observador—de los sujetos; (2) que la estabilidad de las causas determina la predicción de reincidencia, y que ésta es mayor en los sujetos que dicen haber cometido más robos, y (3) que el sentimiento de culpa está determinado por la controlabilidad de las causas y varía como función inversa de la experiencia delictiva. Finalmente, señalamos algunas implicaciones teóricas y aplicadas de este trabajo.     

Disclosure of sexual assault experiences among undergraduate women at historically black colleges and universities (HBCUs)

ABSTRACT

Objective: To document the sexual assault disclosure experiences of historically black college or university (HBCU) students. Participants: A total of 3,951 female, undergraduate students at 4 HBCUs. Methods: All women at the participating schools were recruited in November 2008 to participate in a Web-based survey including both closed- and open-ended questions. Survey data were weighted for nonresponse bias. Results: The majority of sexual assault survivors disclosed their experience to someone close to them, but disclosure to formal supports, particularly law enforcement agencies, was extremely rare. Nonreporters had concerns about the seriousness of the incident and their privacy. On the basis of qualitative data, strategies identified by students to increase reporting included more education and awareness about sexual assault, more survivor services and alternative mechanisms for reporting, and better strategies for protecting the confidentiality of survivors. Conclusions: Official sexual assault victimization data are of limited utility in conveying the extent of sexual assault among HBCU students, and efforts to increase reporting, such as peer education and enhanced confidentiality procedures, are needed.     

A new mathematical approach for the estimation of the AUC and its variability under different experimental designs in preclinical studies

The aim of the present work was to develop a new mathematical method for estimating the area under the curve (AUC) and its variability that could be applied in different preclinical experimental designs and amenable to be implemented in standard calculation worksheets. In order to assess the usefulness of the new approach, different experimental scenarios were studied and the results were compared with those obtained with commonly used software: WinNonlin® and Phoenix WinNonlin®. The results do not show statistical differences among the AUC values obtained by both procedures, but the new method appears to be a better estimator of the AUC standard error, measured as the coverage of 95% confidence interval. In this way, the new proposed method demonstrates to be as useful as WinNonlin® software when it was applicable. Copyright © 2011 John Wiley & Sons, Ltd.     

Self-Help:

The Strengthening the Informal Support System of the Hispanic Elderly, a project designed to supply the Hispanic adult caregiver, i.e., relatives, friends and neighbors, with information and social support through a self-help group approach offered experiential learning and facilitated the formation of an informal network in which the participants explored their personal feeling towards the caregiving role, shared problems and concerns and engaged in mutual problem-solving activities. The project was conducted with fifty-eight persons who were the major caregivers of Hispanic elderly residing in four selected sites throughout New York City.     

Developments in General and Syndromic Surveillance for Small Area Health Data

In this paper we examine a range of issues related to the analysis of health surveillance data when it is spatially-referenced. The importance of considering alarm functions derived from likelihood or Bayesian models is stressed. In addition, we focus on some new developments in predictive distribution residuals in the analysis.     

Sensitivity analysis in ordered and restricted parameter models

This paper deals with the problem of local sensitivity analysis in ordered parameter models. In addition to order restrictions, some constraints imposed on the parameters by the model and/or the data are considered. Measures for assessing how much a change in the data modifies the results and conclusions of a statistical analysis of these models are presented. The sensitivity measures are derived using recent results in mathematical programming. The estimation problem is formulated as a primal nonlinear programming problem, and the sensitivities of the parameter estimates as well as the objective function sensitivities with respect to data are obtained. They are very effective in revealing the influential observations in this type of models and in evaluating the changes due to changes in data values. The methods are illustrated by their application to a wide variety of examples of order-restricted models including ordered exponential family parameters, ordered multinomial parameters, ordered linear model parameters, ordered and data constrained parameters, and ordered functions of parameters.
