This study assessed the effectiveness of an intervention based on a theoretical framework of citizenship on reducing psychiatric symptoms, alcohol use, and drug use, and increasing quality of life for persons with serious mental illness (SMI) and criminal justice involvement. One-hundred fourteen adults with SMI and a history of criminal justice involvement participated in a 2 × 3 longitudinal randomized controlled trial of a four-month citizenship intervention versus usual services. Linear mixed model analyses were used to assess the intervention’s impact on quality of life, symptoms, and substance use. After controlling for baseline covariates, participants in the experimental condition reported significantly increased quality of life, greater satisfaction with and amount of activity, higher satisfaction with work, and reduced alcohol and drug use over time. However, individuals in the experimental condition also reported increased anxiety/depression and agitation at 6 months (but not 12 months) and significantly increased negative symptoms at 12 months. Findings suggest that community-oriented, citizenship interventions for persons with SMI and criminal justice histories may facilitate improved clinical and community outcomes in some domains, but some negative clinical findings suggest the need for post-intervention support for intervention participants. Implications for practice and future research are discussed. 相似文献

In this paper a novel method based on facial skin aging features and Artificial Neural Network (ANN) is proposed to classify the human face images into four age groups. The facial skin aging features are extracted by using Local Gabor Binary Pattern Histogram (LGBPH) and wrinkle analysis. The ANN classifier is designed by using two layer feedforward backpropagation neural networks. The proposed age classification framework is trained and tested with face images from PAL face database and shown considerable improvement in the age classification accuracy up to 94.17% and 93.75% for male and female respectively. 相似文献

In item response theory (IRT), the invariance property states that item parameter estimates are independent of the examinee sample, and examinee ability estimates are independent of the test items. While this property has long been established and understood by the measurement community for IRT models, the same cannot be said for diagnostic classification models (DCMs). DCMs are a newer class of psychometric models that are designed to classify examinees according to levels of categorical latent traits. We examined the invariance property for general DCMs using the log-linear cognitive diagnosis model (LCDM) framework. We conducted a simulation study to examine the degree to which theoretical invariance of LCDM classifications and item parameter estimates can be observed under various sample and test characteristics. Results illustrated that LCDM classifications and item parameter estimates show clear invariance when adequate model data fit is present. To demonstrate the implications of this important property, we conducted additional analyses to show that using pre-calibrated tests to classify examinees provided consistent classifications across calibration samples with varying mastery profile distributions and across tests with varying difficulties. 相似文献

The growing use of mass customization necessitates an understanding of consumers' evaluations of mass customization platforms. We hypothesize that consumers' objective and subjective knowledge of the customized product moderate the influence of idiosyncratically evaluated (i.e., personalizable) attributes on satisfaction with a customization platform. Consistent with our theoretical framework, results from three experiments show that offering greater variety in idiosyncratically evaluated attribute options increases consumers' satisfaction to a greater extent for: (1) novices than experts (2) consumers with more subjective knowledge, and (3) miscalibrated consumers whose subjective knowledge does not match their objective knowledge, than calibrated consumers whose subjective and objective knowledge match. 相似文献

During the last few decades, several multi‐criteria decision analysis methods have been proposed to help in selecting the best compromise alternatives. Among them, analytic hierarchy process (AHP) and its applications have attracted much attention from academics and practitioners. However, since the early 1980s, critics have raised questions regarding its proper use. One of them concerns the unacceptable changes in the ranks of the alternatives, called rank reversal, upon changing the structure of the decision. Several modifications were suggested to preserve ranks. In this paper, a classification scheme and a comprehensive literature review are presented in order to uncover, classify and interpret the current research on AHP methodologies and rank reversals. On the basis of the scheme, 61 scholarly papers from 18 journals are categorized into specific areas. The specific areas include the papers on the topics of adding/deleting alternatives and the papers published in adding/deleting criteria. The scholarly papers are also classified by (1) year of publication, (2) journal of publication, (3) authors' geographic location and (4) using the AHP in association with other methods. It is hoped that the paper can meet the needs of researchers and practitioners for convenient references of AHP methodologies and rank reversals and hence promote the future of rank reversal research.

Classifications in psychiatry can result in the reification of hypothetical approaches, arbitrary categorisation and social injustice. This article applies a social constructivist approach to critique the DSM-5 as a neurobiological model of psychiatric diagnosis which ignores psychosocial factors such as poverty, unemployment and trauma as causes of mental distress. It challenges the universality of psychiatric diagnosis and proposes that cultural psychiatry's framing of ‘culture-bound syndromes,’ or ‘cultural case formulation’ guidelines, is oversimplified. Use of the DSM in the South African context risks perpetuating injustice by labelling and stigmatising people who have in the past been racially stigmatised by apartheid. In culturally diverse South Africa, psychiatric diagnosis should take into account alternative explanatory models that provide a more balanced view of the complex and dynamic relationship between biological and sociocultural forces in the manifestation of psychopathology. 相似文献

The objective this article is to describe five practice guidelines for counsellors working with people of African ancestry in a sport context. The practice guidelines pertain to counsellor training, counsellor perspectives, counsellor services, counsellor ethics and counsellor research. These practice guidelines can assist counsellors working with people of African ancestry in a sport context to focus on both personal development through sport and performance enhancement in sport. This will enable athletes not just to view sport in terms of their win-lose record, but to also strive for excellence in sport by becoming better people. In becoming better people athletes can contribute to building up Africa and her people. 相似文献

The purpose of the paper is to discuss the formidable challenges to community reentry and reintegration faced by U.S. prison inmates with serious mental illness and to describe various strategies for improving transitional services for these individuals. We review epidemiologic data supporting the high prevalence of severe mental illness in U.S. prisons as well as the historical factors underlying the criminalization of the mentally ill. The importance and challenges of providing adequate psychiatric care for mentally ill prisoners during their incarceration are discussed. We also review the numerous psychosocial and economic challenges confronting these individuals upon their release from prison, such as unemployment and vulnerability to homelessness, as well as specific barriers they may encounter in attempting to access community-based mental health services. We follow with a discussion of some of the more promising strategies for improving the transition of the mentally ill from prison to the community. In the final sections, we review the evidence for a relationship between serious mental illness and recidivism and briefly discuss emerging alternatives to incarceration of the mentally ill. 相似文献

Using taxometric procedures, the latent structure of psychopathy was investigated in two studies of children and adolescents. Prior studies have identified a taxon (i.e., a natural category) associated with antisocial behavior in adults as well as children and adolescents. However, features of this taxon suggest that it is not psychopathy but rather a broader class consistent with the construct of life course persistent antisocial behavior. Because the only prior study of youth used a non-clinical sample, the base rate of psychopathy may have been too low to reveal a psychopathy taxon, especially against the background of a broader and more prevalent antisocial behavior taxon. Therefore, this investigation sought to increase the likelihood of finding a psychopathy taxon (should one exist) by increasing its expected base rate through inclusion of clinical cases in the samples studied. Results produced evidence for both a broad antisocial behavior problem taxon consistent with past research and a much lower base rate taxon consistent with prevalence expectations for psychopathy. These findings support the existence of latent taxa for both psychopathy and a broader class of antisocial behavior problems. Further taxometric research appears to be warranted, which should use a broader array of indicators, with greater specificity to psychopathy. 相似文献
