A Weibull Regression Model with Gamma Frailties for Multivariate Survival Data

Frequently in the analysis of survival data, survival times within the same group are correlated due to unobserved co-variates. One way these co-variates can be included in the model is as frailties. These frailty random block effects generate dependency between the survival times of the individuals which are conditionally independent given the frailty. Using a conditional proportional hazards model, in conjunction with the frailty, a whole new family of models is introduced. By considering a gamma frailty model, often the issue is to find an appropriate model for the baseline hazard function. In this paper a flexible baseline hazard model based on a correlated prior process is proposed and is compared with a standard Weibull model. Several model diagnostics methods are developed and model comparison is made using recently developed Bayesian model selection criteria. The above methodologies are applied to the McGilchrist and Aisbett (1991) kidney infection data and the analysis is performed using Markov Chain Monte Carlo methods.

Faith‐Based Social Service Organizations and Government Funding: Data from a National Survey*

Objective. The objective of the research reported in this article is to test four hypotheses concerning government funding among faith‐based social service coalitions: that it is positively related to size and organizational professionalism; positively related to attitudes toward government funding; positively related to social activism; and negatively related to organizational religiosity. Method. Our method is the application of OLS and probit analysis to data from a national survey of 656 such organizations. Results. Using three measures of government funding and 12 predictor variables, results are mixed in their support of the size and professionalization hypothesis and generally support the remaining hypotheses. These findings are replicated when we compare coalitions that had and had not applied for government funding. Conclusions. Our findings emphasize that greater religious expressiveness dissuades coalitions from both seeking and receiving government funding, but higher levels of social activism expedite both.     

The Single Assessment Process in Primary Care: Older People's Accounts of the Process

Recent government policies have been active in addressing socialinclusion and active participation of older people in many aspectsof societal life. Independence and well-being animate thesedevelopments and are evident in the emphasis on person-centredservices within the single assessment process for older people(Department of Health, 2002b). Drawing on a feasibility study of the Single Assessment Processas a ‘case-finding’ approach, this paper presentsfindings drawn from older people’s accounts of this experience.These accounts indicate the potential of the process for identifying‘low-level’ need, whilst raising issues of accessto formal services and resource constraint; also they underlinethe importance of understanding how older people seek ways ofmanaging their own health and well-being, whilst continuingto contribute to the social cohesion of society by providingsupport to their peers and to younger generations. Interdependence, it is suggested, rather than dependence shouldunderlie any approach to assessing older people’s needs,if we are to appreciate and build upon the complexity of olderpeople’s strategies for actively managing their lives.     

Student‐Perceived Mothers’ and Fathers’ Beliefs,Mathematics and English Motivations,and Career Choices

According to Eccles and Jacobs' (1986) parent socialization model, parents’ gendered ability and value beliefs influence girls’ and boys’ interpretations of those beliefs, and hence students’ domain‐specific valuing of tasks and competence beliefs and subsequent career plans. Studies have rarely analyzed how both student‐perceived mothers’ and fathers’ beliefs affect girls’ and boys’ task values, success expectancies, and career plans across domains. This study analyzed survey data of 459 students (262 boys) assessed through Grades 9, 10, and 11 from three coeducational secondary schools in Sydney, Australia. Longitudinal structural equation models revealed gendered value transmission pathways for girls in mathematics. Although mathematics test scores did not vary statistically significantly, girls reported statistically significantly lower mothers’ ability beliefs for them in mathematics than boys at Time 1, which led to their statistically significantly lower mathematics intrinsic value at Time 2 and mathematics‐related career plans at Time 3. Such gendered pathways did not occur in English. Matched same‐gender effects and gendered pathways in parent socialization processes were evident; perceived mothers’ value beliefs were more strongly related to girls’ than boys’ importance values in English. Student‐perceived fathers’ ability beliefs positively predicted boys’, not girls’, importance value in mathematics. Implications for educational practice emphasize the need to target girls’ and boys’ interest when aiming to enhance their mathematical career motivations.     

Factors affecting the constancy of the intelligence quotients of problem children 1

Abstract

This theoretical study is based on the premise that the dynamics of metaphor, the joining of two disparate entities in a single relational field to produce a new concept, represent a prototype of change. Literature is reviewed as it applies to certain relationships between metaphor and psychotherapy. As both metaphor and psychotherapy are rooted in language, language is viewed both as it informs the self and as it is used as a tool of psychotherapy. Psychoanalytic theory of language development is presented as are theories of how language, specifically metaphor, might be integrated and influence the change process.
