Computing continuous core/periphery structures for social relations data with MINRES/SVD

When diagonal values are missing or excluded, MINRES is a natural continuous model for the core/periphery structure of a symmetric social network matrix. Symmetric models, however, are not so useful when dealing with asymmetric data. Singular value decomposition (SVD) is a natural choice to model asymmetry, but this method also requires the presence of diagonal values. In this paper we offer an alternative, more general, approach to continuous core/periphery structures, the minimum residual singular value decomposition (MINRES/SVD), where each node in the network receives two indices, an “in-coreness” and an “out-coreness.” The algorithm for computing these coreness vectors is a least squares computation similar to, but distinct from the SVD, again because of the missing diagonal values. And in contrast to the standard, symmetric MINRES algorithm, we can more accurately model asymmetric matrices. This allows us to distinguish, for example, countries in the world economy that are more in the exporting core than they are in the importing core. We propose two nested PRE (proportional reduction of error) measures of fit: (1) the PRE from the MINRES vector with respect to the data and (2) the PRE of the product of the two MINRES/SVD vectors. Applying the resulting method to citations between journals and to international trade in clothing, we illustrate insights gained from being able to model asymmetrical flow patterns. Finally, two permutation tests are introduced to test independently for the MINRES and MINRES/SVD results.     

"Talking in a new way": older individuals' experiences of group work in an acute psychiatric ward

Group work is frequently used in mental health, however qualitative studies on service-users' views are rare. Semistructured interviews explored 12 participants' experiences of a café-style social group and a mutual-aid group offered on an older persons psychiatric ward in Christchurch, New Zealand. The values of the strengths-based approach underpinning the groups were reflected back in the experience of an affirming environment, an exchange of strengths, and the capacity to change. The appeal of the café-style may be culturally specific to European women however, reinforcing the importance of an awareness of culture and diversity.     

The social dimensions of happiness and life satisfaction of Australians: Evidence from the World Values Survey

Relatively short‐term verbal therapies and other forms of intervention may help people to overcome difficult passages in life, but studies in recent decades have pointed to the salience of social and economic conditions in shaping life satisfaction and happiness. The present study contributes to our knowledge of this field by extending the range of social factors considered, but also, crucially, by the employment of statistical analyses that serve to disentangle the often overlapping variables associated with life satisfaction and happiness. Our results support previous ‘demographic’ findings as well as new results including education, marriage, children, human rights and, particularly in the context of Australian society, perceived choice in life. Establishing what the major contributing factors are can assist the formulation of social policy. Moreover, it can alert practitioners to the value of consolidating their work by encouraging service users to utilise community sources that enhance life satisfaction and/or happiness. Key Practitioner Message: ● The informed linking of service users to sources of life satisfaction and happiness can ‘value add’ direct service interventions; ● The salience of exercising individual choice to achieving life satisfaction reinforces the importance of the practice principle of self‐determination; ● A person's sense of physical wellbeing is a relevant part of social assessment and subsequent planned actions.     

Institutions and the Diversity and Prevalence of Multinationals’ Knowledge‐Augmenting Subsidiaries

Multinational corporations (MNCs) increasingly seek to gain access to, and exploit, locationally specific sources of advanced knowledge and technological capabilities, creating a need to explain (1) the diversity among these facilities and (2) how institutions influence MNCs’ abilities to invest in different subsidiary types. Extending debates on firms’ knowledge‐augmenting activities, the authors integrate institutions into their analytical framework to a greater extent than previous work has done. Moreover, existing contributions provide typologies of R&D subsidiaries. In contrast, the authors focus on a particular subset of subsidiaries, knowledge‐augmenting ones, and put forward a theory to explain their variety and their prevalence, enabling them to identify previously neglected subsidiary types that have important managerial and policy implications. By downplaying the diversity of these subsidiaries, existing work has not been able to capture the full range of managerial challenges as well as the costs and benefits of different subsidiary types to host countries. The authors, therefore, problematize firms’ abilities to gain access to foreign knowledge‐generating assets, highlight the importance of institutional environments, provide policy recommendations and identify areas for future research.     

Liminal Stigma and Disaligning Activity: Online Comments about Trump's Family Separation Policy

In 2018, the Trump administration initiated a “zero-tolerance” border policy wherein they criminally prosecuted all individuals who were apprehended crossing the border without proper authorization. The policy change resulted in numerous migrant children being separated from their parents. Through a qualitative content analysis of 1500 YouTube comments made in response to CNN and ProPublica news coverage, we examine each side's aligning activity. Separation challengers claimed border crossers were innocent while condemning their opponents as racist, cruel, and otherwise shameful. Separation advocates bolstered their own claims of innocence by denying that the detainees are victims and condemning separation challengers as hypocrites, dishonest, complicit in illegal immigration, and generally loathsome. These findings show that, enabled by social media, aligning activity in stigma contests can produce a liminal stigma, where identities suffer the ideational aspects of stigma but not necessarily the loss of social status.     

How does inequality aversion affect inequality and redistribution?

We investigate the effects of inequality aversion on equilibrium labor supply, tax revenue, income inequality, and median voter outcomes in a society where agents have heterogeneous skill levels. These outcomes are compared to those which result from the behavior of selfish agents. A variant of Fehr-Schmidt preferences is employed that allows the externality from agents who are “ahead” to differ in magnitude from the externality from those who are “behind” in the income distribution. We find first, that inequality-averse preferences yield distributional outcomes that are analogous to tax-transfer schemes with selfish agents, and may either increase or decrease average consumption. Second, in a society of inequality-averse agents, a linear income tax can be welfare-enhancing. Third, inequality-averse preferences can lead to less redistribution at any given tax, with low-wage agents receiving smaller net subsidies and/or high-wage individuals paying less in net taxes. Finally, an inequality-averse median voter may prefer higher redistribution even if it means less utility from own consumption and leisure.     

Investigating the mediational role of negative urgency in the anxiety sensitivity pathway to cannabis problems and dependence symptoms among postsecondary students

Objectives: Anxiety sensitivity (AS) is associated with cannabis use. People high in AS may use cannabis to cope with elevated anxiety. This association is consistently supported in the literature. However, we have much to learn about the mechanisms of the AS pathway to cannabis use. We aimed to examine negative urgency—the tendency to act impulsively when distressed—as a mediator of the association of AS with cannabis problems and cannabis dependence symptoms. We hypothesized that negative urgency would uniquely mediate the association of AS with cannabis outcomes after controlling for other facets of impulsivity. Participants and Methods: Postsecondary students (N = 91; Fall 2012) completed online self-reports. To participate, students needed to be ≥18 years old, enrolled in postsecondary studies, and needed to report current cannabis use. Results: Negative urgency uniquely mediated associations between AS and cannabis problems and dependence symptoms. Conclusions: Our findings suggest a mechanistic role of negative urgency in the AS pathway to cannabis misuse.     

What Explains the Decline in First Marriage in the United States? Evidence from the Panel Study of Income Dynamics, 1969 to 2013

Rates of entry into first marriage have declined sharply in the United States during the past half century, and there is evidence of broad gaps in marriage entry by race and education. Although a large literature explores the influences on marriage for single cohorts, there is little research that tests explanations for this decline across multiple cohorts. The authors use individual and contextual measures of employment and incarceration to predict transitions to first marriage in the Panel Study of Income Dynamics (1969–2013). They test two prominent theories of why marriage rates have declined: the decreased availability of “marriageable” men and the increased economic standing of women. They find that men's reduced economic prospects and increased risk of incarceration contributed to the decline in first marriage rates during the past 45 years in the United States, although these basic measures of economic and carceral conditions cannot explain the entire decline.
