Therapeutic residential care (TRC) is the name given to specialized children's homes for treating cases with severe emotional and behavioural problems that have been placed in residential care. A recent international review has revealed great diversity in the referral criteria of cases and in the models of intervention carried out. The goal of this study is to describe the population treated in these types of facilities in Spain and the therapeutic coverage given. The sample is made up of 215 young people in children's homes, of whom 93 are in TRC. The cases referred to TRC have been in residential care for less time but have gone through a greater number of placements. These young people also exhibit more problems of drug use, and there is a larger percentage of clinical‐range cases in the Child Behaviour Checklist scales of attention problems and aggressive behaviour. Nevertheless, the results of logistic regression indicate that the only variables that significantly increase the probability of being referred to TRC are drug use and changes of care placements. With regard to therapeutic care, there is a higher percentage in the TRC group receiving psychiatric care, and the sessions are also more frequent.  相似文献

This study compared the memory, attention/concentration, and executive functioning of 12 women with histories of child sexual abuse with a control group of 12 women without childhood abuse. Participants completed a neuropsychological test battery and various instruments assessing post-traumatic stress disorder and dissociation. The child sexual abuse group had lower performance than the control group on long- and short-term visual and verbal memory and presented more limited performance on executive functioning tasks. Functioning in these areas showed a negative correlation with post-traumatic stress disorder and dissociative symptoms. These findings suggest that child sexual abuse is associated with memory and executive functioning deficits and supports the idea that people with trauma histories and increased post-traumatic stress disorder and dissociation symptoms may have alterations in neuropsychological functioning.  相似文献

Resumen

En este trabajo se estudia la percepción del delito desde la perspectiva de los episodios sociales. Los objetivos más importantes de nuestra investigación fueron: a) aislar y comparar las dimensiones que subyacen a la percepción del delito en tres grupos de sujetos: delincuentes institucionalizados, profesionales del sistema penal y grupo de personas no vinculadas al sistema penal; y b) ver si existen diferencias en la percepción de tres de los tipos de delitos establecidos en el Código Penal español. La muestra estuvo compuesta por un total de 272 sujetos, todos ellos varones, procedentes de los tres grupos en estudio. Las puntuaciones dadas por estos sujetos a 22 episodios delictivos fueron sometidas a escalamiento multidimensional. Se obtuvo un espacio multidimensional de cuatro dimensiones para cada uno de los grupos y se constataron diferencias entre ellos. Las puntuaciones de los episodios en cada dimensión permitieron discriminar de forma significativa entre los tres tipos de delitos. Los resultados se discuten integrando la perspectiva de los episodios sociales y la teoría de la atribución.  相似文献

This paper contributes to the literature on the effect of venture capital (VC) on the economic development of areas in which those specialized investors are active. The work focuses on the separate consideration of two effects that are supposed to explain the superior performance of a large sample of Spanish VC-backed firms, namely funding and value-added services provided by VC managers to their investee firms. The results show that funding is significant regardless of the stage of development of the investee firm. The value added, however, is only significant for the subsample of firms at the expansion stage.  相似文献

Do social policies in Latin America promote or discourage distribution? And if they do promote distribution, are coalitions a prerequisite? Drawing from a typology of welfare regimes elaborated for 18 Latin American countries, this article explores responses to these questions by addressing three emblematic cases: Chile, Costa Rica and El Salvador – that is, countries where the management of social risks primarily revolves around markets, states and families, respectively. Although the article is exploratory, findings suggest that societal coalitions have been, and are likely to continue to be, weak in market welfare regimes, strong in state welfare regimes and contingent to policy sectors in familialistic welfare regimes.  相似文献

During the last decade, family formation patterns in Spain have undergone a process of substantial transformation. Younger cohorts are increasingly postponing marriage and, once they enter marriage, they tend to delay childbearing. Partly as a result of these timing shifts, period measures such as total fertility rates are likely to underestimate true fertility levels. This study focuses on the first stage of family formation: the transition to motherhood. Following a birth interval approach, the analysis depicts recent trends and differentials in the timing of first birth and explores the role of premarital pregnancies and contraceptive practice on first interval dynamics.Durant la dernière décennie en Espagne, les types de constitution de la famille ont connu de substantielles transformations. Les plus jeunes cohortes prolongent leur célibat et, une fois mariées, tendent à retarder leurs naissances. En partie comme un effet de ces changements temporels, les mesures transversales, telles que la fécondité cumulée, sous-estiment vraisemblablement les vrais niveaux de la fécondité. Cette étude concentre son attention sur la prémière étape de la formation des familles: la transition vers la maternité. En utilisant une approche longitudinale, on analyse les tendances et les différences dans le calendrier de la première naissance et l'on explore le rôle des grossesses prémaritales et des pratiques contraceptives sur la dynamique de l'intervalle entre mariage et première naissance.

In order to reach the inference about a linear combination of two independent binomial proportions, various procedures exist (Wald's classic method, the exact, approximate, or maximized score methods, and the Newcombe-Zou method). This article defines and evaluates 25 different methods of inference, and selects the ones with the best behavior. In general terms, the optimal method is the classic Wald method applied to the data to which z 2 α/2/4 successes and z 2 α/2/4 failures are added (≈1 if α = 5%) if no sample proportion has a value of 0 or 1 (otherwise the added increase may be different).

An extensive literature review was carried out to detect why design of experiments (DoE) is not widely used among engineers in Europe. Once 16 main barriers were identified, a survey was carried out to obtain first-hand information about the significance of each. We obtained 101 responses from academics, consultants and practitioners interested in DoE. A statistical analysis of the survey is introduced, including: (a) a ranking of the barriers, (b) grouping of barriers using factorial analysis, (c) differences between characteristics of respondents. This exploratory analysis showed that the main barriers that hinder the widespread use of DoE are low managerial commitment and engineers’ general weakness in statistics. Once the barriers were classified, the most important resultant group was that related to business barriers.  相似文献
