ABSTRACT

The purpose of this action research project was to gain an understanding of, and to mobilise the voices of diverse young people enrolled in a Portuguese secondary school. A case study methodology, in conjunction with action research methodology, was used for this study. The action research data indicated that projects conceived throughout the study were successful in mobilising the voices of 14 young secondary school students in decision-making processes. The young people engaged democratically, made informed decisions about themselves and their peers, managed conflicts, and reinforced the importance of interpersonal relationships. These changes took place at the individual, as well as group levels.  相似文献

A challenging problem in the analysis of high-dimensional data is variable selection. In this study, we describe a bootstrap based technique for selecting predictors in partial least-squares regression (PLSR) and principle component regression (PCR) in high-dimensional data. Using a bootstrap-based technique for significance tests of the regression coefficients, a subset of the original variables can be selected to be included in the regression, thus obtaining a more parsimonious model with smaller prediction errors. We compare the bootstrap approach with several variable selection approaches (jack-knife and sparse formulation-based methods) on PCR and PLSR in simulation and real data.  相似文献

The purpose of this study was to discover the characteristics of innovative organizations as perceived by employees of Argentine nonprofit organizations. The free listing technique, adapted from the field of cognitive anthropology, was used to achieve this task. Fifteen representatives of a variety of Argentinean nonprofit organizations participated in the study. Among the highest rated characteristics were: searching for new ways, solutions, and unconventional forms of work; adapting to new times; suggesting new forms for solving problems; and reflecting over organizational activities and actions. Rated as least characteristic were: encouraging role changes within teams; focusing on organizational mission; not being afraid of failure; and generosity (sharing information with other organizations).  相似文献

Resumen

El propósito del estudio fue identificar las tendencias evolutivas en la construcción de la representación de la organización social en relación con las nociones de pobreza-riqueza, estratificación y cambio social autoconceptualización, trabajo, contexto e instituciones sociales. Se realizaron entrevistas semiestructuradas sobre dichas nociones con una muestra de 90 escolares mexicanos de 6 a 15 años de nivel socioeconómico bajo. Los niños pequeños explicaron la organización social en función de factores aislados, individualistas o únicos, caracterizando las clases sociales en términos de atributos observables (dinero y posesiones). En la niñez media y adolescencia, aunque siguen preponderando las explicaciones individualistas, se incrementan gradualmente las basadas en la consideración de varios factores y en la intervención de acciones colectivas e instituciones sociales.  相似文献

This study analyzed which family and couple variables predicted adherence to standard care treatment, in patients recently diagnosed with type 2 diabetes. The sample comprised 224 dyads assessed during the first year of diagnosis (T1) and 4 months later (T2). The results showed that family stress, dyadic adjustment, family coping, and positive support assessed by patients at T1 predicted medication adherence and glucose monitoring at T2. Positive support and dyadic adjustment, assessed by partners at T1, predicted patients' adherence to glucose monitoring and diet at T2. This study highlights the important role of the partner in patient`s adherence. Therefore, standard care in type 2 diabetes should be offered in the context of the dyad.  相似文献

Intimate partner violence that takes place in first couple relationships has received increasing attention in recent years, leading our knowledge on different topics to grow remarkably. The objective of this study is two-fold: on the one hand, we compare levels of victimization and tolerance for two samples, from two waves of assessment; and on the other hand, we focus on coherence among victimization and the use of labels such as abuse, fear and feeling trapped in the relationship in both waves. A total sample of 3,844 women between the ages of 16 and 21 took part in the study, 18% in the first wave in 2003–05 and 82% in the second wave in 2011–13. Data were collected using the Cuestionario de Violencia de Novios (CUVINO), a questionnaire that provides information on the prevalence of and tolerance towards eight different kinds of abuse, along with self-labelling questions on the perception of abuse. Results showed a similarity in prevalence and labelling in both waves of assessment, with higher tolerance in the second wave. We discuss the implications of these findings for improving current prevention programs on dating violence.  相似文献

We implemented and evaluated a service delivery intervention (support model) to address the challenges faced by migrant agricultural workers in British Columbia, Canada. Three factors were identified that contributed to the effectiveness of the intervention: (1) face-to-face support and in-person outreach towards connection; (2) accounting migrant workers' hierarchy of needs and addressing their basic needs first towards comprehensiveness; and (3) role clarity and communication between partners involved in supporting this population towards coordination. A final factor, wider constraints, referred to the wider context of migrant workers' lives including their temporary status, tied work permits, and lack of access to rights. These wider constraints, which were exacerbated by the COVID-19 pandemic, underscore that until greater policy action is taken to address these workers' precarious status, support services can only offer a lifeline in troubled waters.  相似文献

Parental sense of competence is one of the central dimensions targeted on psychosocial interventions aimed at supporting at‐risk families. Researchers and practitioners need reliable instruments to assess the parental role adapted for these families. Although the parental sense of competence (PSOC) scale has been frequently used to assess this construct, there is still no adapted version for Portuguese parents. In this study, the reliability, validity and factor structure of the PSOC scale is examined with a clinical sample of 146 mothers from at‐risk families receiving psychosocial interventions for family preservation from Child Protective Services. Results show that the Portuguese version of the PSOC measures three distinct constructs with acceptable psychometric properties: efficacy, dissatisfaction and controllability. As expected, the obtained factors were significantly and positively related to parenting alliance and family cohesion, and negatively associated with parenting stress. In sum, the proposed Portuguese version shows reliability and validity evidences to measure three relevant dimensions of parental self‐evaluation, and it constitutes a cost‐ and time‐effective instrument suited for at‐risk mothers.  相似文献

The age of a patient is a strong moderator of both the course and the evolution of disorders/diseases. However, the effects of current age in pathological gambling (PG) have rarely been examined. The aim of this study is to explore the moderating effects of the patients’ current age in relation to personality traits and clinical outcomes of PG. A total sample of 2,309 treatment-seeking patients for PG, diagnosed according to DSM-IV criteria, participated in this study and were assessed with the Diagnostic Questionnaire for Pathological Gambling according to DSM-IV criteria, the South Oaks Gambling Screen, the Symptom Checklist, the Temperament and Character Inventory-R, and other clinical and psychopathological measures. Orthogonal polynomial contrasts showed linear trends in the relationship between age and PG: the older the patient, the more comorbid health problems were visible. The presence of additional quadratic trends also suggests that age plays a significant role in moderating the possibility of existing PG problems and general psychopathology. No interaction term was found between age and sex, but it was present for age and some personality traits: self-transcendence and reward dependence (these two traits were only relevant to the level of impairment due to PG at specific ages). This study suggests that the patients’ age influences psychopathological and clinical aspects associated to PG. Intervention in the earliest manifestations of this complex problem is essential in order to better address the need of successful treatment planning.  相似文献
