Semiparametric inference for survival models with step process covariates

The authors consider Bayesian methods for fitting three semiparametric survival models, incorporating time‐dependent covariates that are step functions. In particular, these are models due to Cox [Cox ( 1972 ) Journal of the Royal Statistical Society, Series B, 34, 187–208], Prentice & Kalbfleisch and Cox & Oakes [Cox & Oakes ( 1984 ) Analysis of Survival Data, Chapman and Hall, London]. The model due to Prentice & Kalbfleisch [Prentice & Kalbfleisch ( 1979 ) Biometrics, 35, 25–39], which has seen very limited use, is given particular consideration. The prior for the baseline distribution in each model is taken to be a mixture of Polya trees and posterior inference is obtained through standard Markov chain Monte Carlo methods. They demonstrate the implementation and comparison of these three models on the celebrated Stanford heart transplant data and the study of the timing of cerebral edema diagnosis during emergency room treatment of diabetic ketoacidosis in children. An important feature of their overall discussion is the comparison of semi‐parametric families, and ultimate criterion based selection of a family within the context of a given data set.

Radical Normals: The Moral Career of Straight Parents as Public Advocates for Their Gay Children

Sociological research has examined straight parents in “traditional” family arrangements who become gay rights activists, but pays insufficient attention to how this puzzling identity comes into being. Drawn from observations and interviews of parents participating in a local chapter of Parents and Friends of Lesbians and Gays (PFLAG) (2009 to 2010), this paper analyzes the parenting activities undertaken by straight parents of gay children as a moral career, involving stages of acceptance that can lead to eventual public advocacy. Paradoxically, these parents become radical normals through these stages; that is to say, they “do” the work of parenting by becoming gay rights advocates, motivated by commitments to conventional imperatives of loving and supporting a child. Using the conceptual scaffolding of the moral career, this paper identifies the mechanisms that move parents through these different career stages.     

Sample Heterogeneity and the Measurement Structure of the Multidimensional Students’ Life Satisfaction Scale

Several measurement assumptions were examined with the goal of assessing the validity of the Multidimensional Students’ Life Satisfaction Scale (MSLSS), a measure of adolescents’ satisfaction with their family, friends, living environment, school, self, and general quality of life. The data were obtained via a cross-sectional survey of 8,225 adolescents in British Columbia, Canada. Confirmatory factor and factor mixture analyses of ordinal data were used to examine the measurement assumptions. The adolescents did not respond to all the MSLSS items in a psychometrically equivalent manner. A correlated five-factor model for an abridged version of the MSLSS resulted in good fit when all negatively worded items and several positively worded items (the least invariant) were excluded. The abridged 18-item version of the MSLSS provides a promising alternative for the measurement of five life domains that are pertinent to adolescents’ quality of life.     

Terror, Resource Gains and Exclusionist Political Attitudes among New Immigrants and Veteran Israelis

This study analyses the antecedents of exclusionist political attitudes towards Palestinian citizens of Israel among Israeli immigrants from the former Soviet Union in comparison to Old Jewish Israelis (OJI). A large-scale study of exclusionist political attitudes was conducted in the face of ongoing terrorism in Israel through telephone surveys carried out in September 2003 with 641 OJI and 131 immigrants. The main goal of the survey was to estimate the influence of perceived loss and gain of resources-as a consequence of terror-on attitudes towards Palestinian Israelis, while controlling for other relevant predictors of exclusionism-i.e. authoritarianism or threat perception. Findings obtained via interaction analyses and structural equation modelling show that a) immigrants display higher levels of exclusionist political attitudes towards Palestinian citizens of Israel than OJI; b) loss of resources, authoritarianism, and hawkish (rightist) worldviews predict exclusionist political attitudes among both immigrants and non-immigrants; c) failure to undergo post-traumatic growth (resource gain) in response to terrorism (e.g. finding meaning in life, becoming closer to others) is a significant predictor of exclusionist political attitudes only among immigrants.     

Evidence-Based Practice in Social Work: Challenges and Opportunities for Clinicians and Organizations

Evidence-based practice (EBP) is increasingly emphasized in social work, yet effective approaches for translating research evidence into social work practice remain elusive. Despite a growing body of evidence describing effective interventions with a variety of populations, social workers continue to encounter substantial challenges with incorporating knowledge gained from these intervention studies into their routine practice with clients. This paper presents the current research outlining the known barriers and promoters to using EBP in social work clinical practice. Because social workers practice within the context of organizations, we consider the barriers that exist at both the individual and organizational levels that affect clinical social work practice. In addition to addressing the various challenges to incorporating research evidence into practice, we will also discuss a variety of emergent opportunities accompanying the move toward EBP that can be leveraged by clinicians in their social work practice with clients.     

Examining Attachment Avoidance and Attachment Anxiety Across Eight Sessions of Couple Therapy

This study examined initial levels of attachment anxiety and avoidance, as well as their patterns of change, across eight sessions of couple therapy. Participants were 461 couples in a treatment‐as‐usual setting. Dyadic latent growth modeling was used to determine whether couples started therapy at similar levels of attachment anxiety and avoidance and whether attachment anxiety and avoidance changed. An actor partner interdependence model was used to see whether partner attachment anxiety was related to avoidance. Results showed relative stability of attachment anxiety and avoidance over the course of therapy, with the only change being a slight decline in attachment anxiety among women. Results showed that a person's attachment anxiety was not related to their partner's avoidance and vice versa.     

The political economy of financial inclusion: tailoring donor policy to fit

Financial inclusion has recently become a globally acclaimed policy objective. This provokes the need to review policy in this sector, particularly in light of the tensions that arise between donor approaches founded on market modernism and governments with more activist leanings. This is done here in the context of efforts to move donor development policy beyond ‘best practice’ institutional blue‐prints to those which are ‘good enough’, which seek to understand underlying political economy dynamics in order to find space to engage with governments. In doing so, it is argued that there is scope for ‘working with the grain’ and harnessing the political economy of government policy in order to produce financial inclusion outcomes.     

Global System Theory and ‘Market-friendly’ Religion

This article explores some implications of the interplay of neoliberal economic policy and religion for Leslie Sklair's global system theory (GST), and some implications of Sklair's theory for the study of contemporary religion. We first suggest that Sklair needlessly restricted his theory's scope by analyzing culture in terms of consumerist ideologies without systematic consideration of religious doctrines and practices. Second, based on studies of ‘market Islam’ and our own research on neo-Pentecostal Christianity in Guatemala, we argue that Sklair's notion of a transnational capitalist class is needed for an adequate understanding of the rapid growth of these religious movements. We conclude that GST can benefit from consideration of contemporary religious change, while the study of contemporary religion has perhaps even more to gain from theorizing the influence of transnational elites.
