Beyond recruitment: Predictors of differential participation in a national antihunger organization

Surprisingly little research has sought to explain differential participation after recruitment into social movement organizations (SMOs). This study examines the influence of several sets of predictors on participation by members of a national organization in the antihunger movement. The findings highlight the importance of incentive, ideological, and microstructural factors for differential participation and suggest that favorable perceptions of SMOs also promote participation. Final remarks address the implications of the findings for the social movement and voluntary organization literatures.     

Improved bridge constructs for stochastic differential equations

We consider the task of generating discrete-time realisations of a nonlinear multivariate diffusion process satisfying an Itô stochastic differential equation conditional on an observation taken at a fixed future time-point. Such realisations are typically termed diffusion bridges. Since, in general, no closed form expression exists for the transition densities of the process of interest, a widely adopted solution works with the Euler–Maruyama approximation, by replacing the intractable transition densities with Gaussian approximations. However, the density of the conditioned discrete-time process remains intractable, necessitating the use of computationally intensive methods such as Markov chain Monte Carlo. Designing an efficient proposal mechanism which can be applied to a noisy and partially observed system that exhibits nonlinear dynamics is a challenging problem, and is the focus of this paper. By partitioning the process into two parts, one that accounts for nonlinear dynamics in a deterministic way, and another as a residual stochastic process, we develop a class of novel constructs that bridge the residual process via a linear approximation. In addition, we adapt a recently proposed construct to a partial and noisy observation regime. We compare the performance of each new construct with a number of existing approaches, using three applications.     

Students’ conceptualisations of critical reflection

Critical reflection involves the identification of deeply seated assumptions about the social world and the individual’s connection with it; however, its scope and practice are contested. While ambivalence about its definition remains, critical reflection is described as a threshold concept in social welfare and social work education. This study investigated students’ conceptualisations of critical reflection by analysing the ‘learned’ critical reflection curricula of five core units in an Australian University. A content analysis of 162 assignments submitted by 86 students in 2013 and 2014 was conducted. Findings revealed students conceptualised critical reflection as a process that raised self-awareness, supported the application of theory in practice and, reinforced aspects of their professional identity. However, students adapted the process to fit their purpose and, when personal views clashed with professional practice, rather than examining the tensions that emerged, students privileged professional practice and silenced their personal views. Students did not engage with critical reflection to foster social change; rather their utilitarian approach positioned them to demonstrate competence in professional procedures. These findings highlight the influence of the contexts within which critical reflection is practised and informs the further development of the authors’ pedagogy.     

The unique effects of environmental strategies in health promotion campaigns: a review

Various strategies are used as tools in health promotion campaigns to increase health-related outcomes among target populations. Evaluations of these campaigns examine effects on changing people's knowledge, attitudes, and/or behaviors. Most evaluations examine the combined impact of multiple strategies. Less is known about the unique effects of particular strategies. To address this gap, we used highly systematic methods to identify and review scientifically rigorous evaluations of 18 campaigns that examined the unique effects of three sets of intervention strategies (entertainment education, law enforcement, and mass media) on changes in knowledge, attitudes, and practice with regard to various health behaviors. Results showed differences in evaluation processes based on the type of strategy used to promote campaign messages. For instance, evaluations of mass-media based campaigns were more likely to examine changes in knowledge, relative to evaluations of campaigns that used law enforcement strategies. In addition, campaign effects varied by particular strategies. Mass media-based campaigns were more likely to affect knowledge, relative to behaviors. Law enforcement and entertainment education-based campaigns showed positive effects on behaviors. The implications for planning and evaluating health promotion campaigns are described.     

Single Parenting in the African American Community: Implications for Public Policy and Practice

The percentage of female-headed African American families has increased significantly since the 1960s. It is now estimated that over half of all African American children will grow up in a female-headed household. This article examines factors related to the formation of these households as well as the challenges associated with these households. Policies and programs that have been implemented to treat these families are examined.     

Spousal,Family and Gender Effects on Expected Retirement Age for Married Pre-retirees

The overall purpose of this study was to examine the degree to which retirement is a contextually embedded, family decision rather than an individualized, male-centric one. Using data from a 2010 survey of married pre-retirees ages 35–70 in Michigan, US, we created a General Linear Model to predict expected retirement age. The model incorporated the effect of spousal and family variables on expected retirement age, and because the work/family interface is highly gendered, we explored interactions with gender. The study used a life course perspective in its framing and analysis, and found that expected retirement age was related to both personal and family characteristics and that the relationship of spousal and family factors were gendered and complex.     

Interactional Associations of Gender on Savings Behavior: Showing Gender’s Continued Influence on Economic Action

This study looks at how gender relates to a critical economic behavior—savings activity. We start with the proposition that gender is not merely an additional variable to explain savings choices. Gender is the primary type of social categorization in the U.S. today. Therefore, other variables will be differently relevant to savings depending on gender. We use a national survey, the 2006 Economic Decision Making Survey conducted by Michigan State University’s Institute for Public Policy and Social Research, to examine the proposition. Basic frequencies reveal nonsignificant differences in savings participation across gender, but regression analysis including interactions of gender with other key variables reveals that multiple aspects of individuals’ lives are influenced by gender to predict savings plan participation.     

World Social Forum – possible perspectives

ABSTRACT

In the first part of this essay, I reflect on the divergences of opinion that have always existed in the process of the World Social Forum. This first part was written before the elections in Brazil last autumn. Since then Jair Bolsonaro has been installed as president of Brazil and the divergences I discuss in that first part have cooled down, at least in Brazil. Nevertheless, it remains important to record those divergences when we try to take further our debate about the future of the WSF process, as I do here as well, in the second part of my essay.
