Observations of Adolescent Peer Group Interactions as a Function of Within‐ and Between‐Group Centrality Status

Observations of adolescent (n = 258; M age = 15.45) peer group triads (n = 86) were analyzed to identify conversation and interaction styles as a function of within‐group and between‐group centrality status. Group members' discussions about hypothetical dilemmas were coded for agreements, disagreements, commands, and opinions. Interactions during a hypothetical decision were rated for openness, dominance, aggression, and prosocial behavior. Hierarchical linear modeling revealed that higher within‐group status predicted more disagreements, commands, and less openness than lower within‐group status. Interactions showed that prosocial and aggressive behavior varied as a function of individual status in low‐status but not high‐status groups. Boys, but not girls, engaged in more openness in higher status groups. Results provide insights into peer socialization.     

A cluster tree based model selection approach for logistic regression classifier

Model selection methods are important to identify the best approximating model. To identify the best meaningful model, purpose of the model should be clearly pre-stated. The focus of this paper is model selection when the modelling purpose is classification. We propose a new model selection approach designed for logistic regression model selection where main modelling purpose is classification. The method is based on the distance between the two clustering trees. We also question and evaluate the performances of conventional model selection methods based on information theory concepts in determining best logistic regression classifier. An extensive simulation study is used to assess the finite sample performances of the cluster tree based and the information theoretic model selection methods. Simulations are adjusted for whether the true model is in the candidate set or not. Results show that the new approach is highly promising. Finally, they are applied to a real data set to select a binary model as a means of classifying the subjects with respect to their risk of breast cancer.     

Home is where the heart is: Latinx youth expression and identity in a critical maker project

ABSTRACT

Making has been touted for its potential to democratize STEM yet could be replicating issues of limited participation of persons from educationally underserved populations. This version of making could be problematic for young women of color, limiting participation and aspirations for STEM careers. We present a counterexample with Critical Making, an approach of action, reflection, and community dialog to promote social change. We examine a multimedia design and implementation project as an expression of seven young Latinx¹ women’s experiences. Participants were tasked with creating a maker artifact to display data from a community survey and produced an interactive (touch capacitive) heart-shaped word cloud capturing positive qualities of their community. We utilized cultural-historical activity theory to focus on relations of the teen participants, meanings conveyed by the word cloud, and how digital tools interacted with norms, division of labor, and community relationships to mediate understanding. We report tensions between group versus community values and between possible design features and tool limitations. We also report how participants authored intersecting identities as makers, group members, and contributors to their community. Our results document the dynamics of a Critical Maker program and expand understanding of how young Latinx women experience making and STEM learning.     

A model for the multiplex dynamics of two-mode and one-mode networks,with an application to employment preference,friendship, and advice

We propose a new stochastic actor-oriented model for the co-evolution of two-mode and one-mode networks. The model posits that activities of a set of actors, represented in the two-mode network, co-evolve with exchanges and interactions between the actors, as represented in the one-mode network. The model assumes that the actors, not the activities, have agency.     

The Job Demands-Resources Model in emergency service volunteers: Examining the mediating roles of exhaustion,work engagement and organizational connectedness

Using a sample of 887 volunteer emergency service workers in South Australia, we conducted a study based on the JD-R framework to examine the roles of three mediators in the relationship between job characteristics and volunteer well-being. These were (i) exhaustion as a mediator in the relationships between job demands and both poor mental health and turnover intentions; and (ii) work engagement and organizational connectedness as mediators in the relationships of job resources (training and organizational support) with happiness and turnover intentions. Organizational connectedness, a relatively new construct, is a positive state of well-being that involves an emotional connection with other workers, with service recipients and with aspects of the task and the organization's values. Results indicated that all three mediators were important in explaining volunteer well-being. Specifically, job demands were positively related to exhaustion, which, in turn, was linked to ill-health and turnover intentions. Job resources were positively related to work engagement and organizational connectedness, which were, in turn, negatively related to turnover intentions. However, while organizational connectedness mediated the relationship between job resources and happiness, this was not the case for work engagement. The roles of these variables in future research in paid and voluntary work are discussed.     

Paternal supervisor gatekeeping: How supervising fathers hinder other fathers at work in their uptake of flexible work arrangements

This study explores the role that supervisors play in the low uptake of Flexible Work Arrangements (FWA) among fathers in France. We draw on 28 interviews with fathers who had requested access to FWA and reported on the reaction of their supervisors. These supervisors were all fathers themselves and had previously benefitted from such arrangements themselves, but did not grant such policies to other fathers. To understand these unexpected findings, we conducted an additional 16 interviews with supervising fathers in organizations who had previously enjoyed similar FWA. The findings show that supervising fathers can act as barriers to other fathers in their organizations who try to push for more gender equality. We identified four ways in which supervisors tend to dissuade fathers from accessing policies to which they are entitled: gender-role confirming discourses; career threats; practical reasons as a justification; and a lack of paternal workplace support. The findings highlight the role of men (in this case, supervising fathers) in the lack of increasing gender equality at work. By showing that fathers can function as ‘paternal supervisor gatekeepers’ for other fathers in their organizations, we open up new fruitful ways for studying gender equality in organizations.     

Reproductive justice for the invisible infertile: A critical examination of reproductive surveillance and stratification

The ability to decide if, when, and how often to reproduce is a human right and a biomedical and sociopolitical goal. Infertility impinges upon this right by restricting the ability of individuals and couples to meet their reproductive desires. While biomedical interventions to address infertility have proliferated recently, their distribution has been inequitable; inequalities in rates of infertility, infertility‐specific distress, and access to reproductive healthcare to address infertility abound. Using a reproductive justice framework, and focusing on the United States, we examine the collection and utilization of the Integrated Fertility Survey Series, the inception and provisions of Title X, and the structural limitations of the private healthcare system. This analysis highlights systematic and linked exclusions of marginalized groups from reproductive health surveillance and the public and private provision of reproductive healthcare, including older, non‐white, working class, LGBTQ, geographically remote, less educated, HIV‐positive, institutionalized, and disabled individuals. Individuals who are excluded from infertility tracking, services, and treatment—the invisible infertile—are limited in their ability to realize their human right to reproductive health. Utilizing existing resources in public and private clinical spaces may be a useful starting point for addressing these disparities, but a broader commitment to equitable and inclusive surveillance and healthcare provision is also needed.     

Life Satisfaction Among Turkish and Moroccan Immigrants in the Netherlands: The Role of Absolute and Relative Income

In this paper we investigate the role of several socio-economic and non-economic factors such as absolute and relative income, education and religion to explain the differences of happiness levels of Turkish and Moroccan Immigrants in the Netherlands by using ordered logit model. We focus on members of the Moroccan and Turkish communities, as these are the two largest non-EU immigrant communities in the Netherlands. Our findings reveal that Moroccans, although they have lower income levels and higher unemployment rates than Turkish immigrants, their happiness level is higher than the Turkish immigrants. In order to understand this dilemma a questionnaire survey was performed to 111 Turkish and 96 Moroccan immigrants in Rotterdam, Amsterdam, Den Haag, Utrecht and Arnhem in 2010. The main purpose is to investigate how reference group’s self-reported life satisfaction is related to the level of absolute income; the level of relative income and other socio-economic factors. The main findings are that for Turkish sample relative income is significantly and negatively correlated with life satisfaction whereas, both absolute income (positively) and relative income (negatively) are significantly correlated with life satisfaction for Moroccan case.     

‘It is like being put through a blender’: inclusive research in practice in an Australian university

Abstract

How can university-based researchers committed to a position of solidarity with, and activism alongside, people with disabilities maintain such a stance in the metric-driven environment of the modern university? How can the academy ensure there is the opportunity for people with disabilities to contribute to production of the knowledge in which they have most at stake, in a wider environment where access to basic services for people with disabilities is precarious? In this article we draw on our experience as a team of university-based and community-based researchers with and without disabilities to reflect on these questions, using a framework of reflexive solidarity to consider practical strategies for strengthening the relationship between disability activism and the academy.
