Nationwide Newspaper Coverage of Same-Sex Marriage: A Community Structure Approach

Using the community structure approach to compare coverage of same-sex marriage in leading U.S. newspapers in 35 major cities nationwide, all articles of 250+ words were sampled from a 5-year span of January 1, 2007, to June 23, 2011, for a total of 577 articles. Articles were coded for “prominence” and “direction,” and then combined into a “Media Vector” score for each newspaper, ranging from .4523 to ?.1067. Initial Pearson correlations revealed three clusters had significant relationships: stakeholder (stakeholder proportions correlating with favorable coverage of stakeholder concerns), buffer (privilege correlating with favorable coverage of human rights issues), and vulnerability (vulnerable populations correlating with coverage favoring their perspectives). The stakeholder cluster includes: (percentage 25–44: r = .506, p = .001; gay market index: r = .432, p = .005; percentage 65+: r = ?.397, p = .009; percentage voting Democratic: r = .335, p = .025; percentage voting Republican: r = ?.330, p = .026). The buffer hypothesis was also confirmed (percentage college educated: r = .465, p = .002; percentage family income of $100,000+: r = .383, p = .012; and percentage professional/technical occupations: r = .300, p = .040). One vulnerability indicator, percentage below the poverty line, was also confirmed (r = ?.297, p = .041). A varimax rotated factor analysis and regression yielded 2 factors accounting for more than 29% of the variance: privilege/gay marketing/political identity, 24%, and Evangelicals, 5%.     

Demography of a ground nesting bird in an urban system: are populations self-sustaining?

Urbanization poses threats to earth’s biota, and retention of remnant native habitat in protected areas within expanding urban boundaries may help alleviate threats to wildlife. However, it is unclear for nearly all nonsynanthropic (i.e., not benefiting from an association with humans) species whether vital rates in urban habitats can sustain populations or if populations persist only through immigration from outside the urban boundary. We conducted a three-year study of spotted towhees (Aves: Pipilo maculatus) breeding in four undeveloped parks in Portland, OR, USA, to measure park-specific seasonal reproductive output (F) and annual adult survival (S_A). We developed a stochastic model that combined F and S_A with an estimate of first-year survival to measure population growth rate (λ) in all parks assumed to be closed to immigration. F differed among parks but S_A did not. Relatively high F was possible because many pairs raised >1 brood/season. When combined with empirical estimates of survival through the 30-day period of post-fledging parental care (S_D = 0.645), only 2 of 4 parks were self-sustaining (i.e., λ > 1.0). However, S_D reflected substantial loss of fledglings to domestic cats (Felis catus). Assuming no loss to cats and either partial compensatory or additive mortality of fledglings substantially improved prospects of population persistence for declining (sink) populations. Moreover, allowing low levels of immigration to sinks reversed population declines in most parks even when vital rates were insufficient to maintain populations. Our results suggest that nonsynanthropic bird species can persist in urban landscapes, but also that offspring mortality in the post-fledging period may be a critical determinant of population viability.     

Ideas in Action: Teaching Qualitative Analytic Methods in Social Work Research through the Analysis of Song Lyrics

This article describes the innovative use of a pop culture source-song lyrics to augment the teaching of qualitative methods in social work research. The use of pop culture sources as learning tools in the MSW curriculum has the potential to enhance the learning experience for students. These techniques have not been applied in the content of MSW research classes. This approach could be advantageous over other typical data sources because it is more accessible to students while also being reflective of a collective identity of people in society. Future work should assess student and educator responses to this pedagogical approach.     

Betting Decision Under Break-Streak Pattern: Evidence from Casino Gaming

Cognitive bias is prevalent among gamblers, especially those with gambling problems. Grounded in the heuristics theories, this study contributes to the literature by examining a cognitive bias triggered by the break streak pattern in the casino setting. We postulate that gamblers tend to bet on the latest outcome when there is a break-streak pattern. Moreover, three determinants of the betting decision under break-streak pattern, including the streak length of the alternative outcome, the frequency of the latest outcome, and gender, were identified and examined in this study. A non-participatory observational study was conducted among the Cussec gamblers in a casino in Macao. An analysis of 1229 bets confirms our postulation, particularly when the streak of the alternative outcome is long, the latest outcome is frequent, and the gamblers are females. The findings provide meaningful implications for casino management and public policymakers regarding the minimization of gambling harm.     

Application of an imputation method for variance estimation under pseudo-likelihood when missing data are NMAR

When data are outcome-dependent non response, pseudo-likelihood yields consistent regression coefficients without specifying the missing data mechanism. However, it is onerous to derive parameter estimators including their standard errors from the regression coefficients under pseudo-likelihood (PL). The present study applies an imputation method to compute the asymptotic standard errors of parameter estimators. The proposed method is simpler than Delta method and it showed similar effect size of the standard errors to bootstrapping in simulation and application studies.     

Examining educational inequalities in two national systems: a comparison of the North African second generation in France and the Mexican second generation in the United States

This paper aims to compare the educational outcomes of children of immigrants in France and in the United States to highlight the ethnic educational inequalities in both countries. The comparison focuses on children from two groups: North Africans in France and Mexicans in the United States. By using two longitudinal datasets, the French Educational Panel Survey and Add Health, we examine aspirations, expectations, and secondary attainment in the two contexts. We explore in particular the role of parental education on attainment. Immigrant families have high educational aspirations in both contexts. North-African families express higher aspirations than native French with similar background, while there are no significant differences between second-generation Mexicans and the majority group net of parental education. Second-generation children are disadvantaged in school in both countries; they are more likely to drop out and less likely to graduate from high school, but most of the disadvantage is related to their social background. Net of social background, the Mexican second generation does not differ from the majority group while the North African second generation is more likely to get the French high school diploma than their peers of French origins, in line with their high aspirations. However, North Africans are more likely to receive the technological baccalauréat than the general baccalauréat.     

Statistical modeling for Bayesian extrapolation of adult clinical trial information in pediatric drug evaluation

Children represent a large underserved population of “therapeutic orphans,” as an estimated 80% of children are treated off‐label. However, pediatric drug development often faces substantial challenges, including economic, logistical, technical, and ethical barriers, among others. Among many efforts trying to remove these barriers, increased recent attention has been paid to extrapolation; that is, the leveraging of available data from adults or older age groups to draw conclusions for the pediatric population. The Bayesian statistical paradigm is natural in this setting, as it permits the combining (or “borrowing”) of information across disparate sources, such as the adult and pediatric data. In this paper, authored by the pediatric subteam of the Drug Information Association Bayesian Scientific Working Group and Adaptive Design Working Group, we develop, illustrate, and provide suggestions on Bayesian statistical methods that could be used to design improved pediatric development programs that use all available information in the most efficient manner. A variety of relevant Bayesian approaches are described, several of which are illustrated through 2 case studies: extrapolating adult efficacy data to expand the labeling for Remicade to include pediatric ulcerative colitis and extrapolating adult exposure‐response information for antiepileptic drugs to pediatrics.     

Fat Monica,Fat Suits,and Friends

This paper examines narratives about fatness that are represented and reproduced by the character of “Fat Monica” played by Courteney Cox in a fat suit on the sitcom Friends. By drawing on David T. Mitchell's framework for analyzing “narrative prosthesis,” I examine how Fat Monica's narratives on Friends represent complex intersections of identities. I argue that fat suits often evoke fatness to support limited and clichéd narratives; however, fat suits may also enable new means of representing and understanding fatness. Through an analysis of the ways in which Fat Monica is represented in the episodes she appears in, three key uses of Fat Monica's fatness are discussed. Firstly, I examine the comic uses of Fat Monica and their relationship between fatness and humour. Next, I examine how Fat Monica storylines represent interlocking narratives of fatness, femininity, and sexual desire. Lastly, I consider how Fat Monica represents the construction of the normative body and claims about fatness and authenticity. Ultimately, Fat Monica illustrates how fatness relates to understandings of humour, gender, social class, and heterosexuality.     

Individual and situational correlates of motivation for skills upgrading: an empirical study

The present research examines the tenability of a number of factors thought to precede an individual's motivation for skills upgrading. Because motivation for skills upgrading is instrumental to training success and is highly malleable, knowing the factors that precede motivation for skills upgrading would help managers and policy makers a great deal in formulating strategies to raise the competitiveness of the workforce. We derive several testable hypotheses from the existing literature and empirically verify the selected antecedents of motivation for skills upgrading. Results based on responses from 413 employees suggest that an individual's attitude towards skills upgrading, self-efficacy, usefulness of skills upgrading, health condition and long-term orientation are positively related to motivation for skills upgrading. Implications for policy makers, managers and researchers are discussed.     

Competition and Coordination in a Two‐Channel Supply Chain

We study competition and coordination in a supply chain in which a single supplier both operates a direct channel and sells its product through multiple differentiated retailers. We study analytically the supply chain with symmetric retailers and find that the supplier prefers to have as many retailers as possible in the market, even if the retailers' equilibrium retail price is lower than that of the supplier, and even if the number of retailers and their cost or market advantage prevent sales through the direct channel. We find that the two‐channel supply chain may be subject to inefficiencies not present in the single‐channel supply chain. We show that several contracts known to coordinate a single‐channel supply chain do not coordinate the two‐channel supply chain; thus we propose a linear quantity discount contract and demonstrate its ability to perfectly coordinate the two‐channel supply chain with symmetric retailers. We provide some analytical results for the supply chain with asymmetric retailers and propose an efficient solution approach for finding the equilibrium. We find numerically that the supplier still benefits from having more retailers in the market and that linear quantity discount contracts can mitigate supply chain inefficiency, though they no longer achieve perfect coordination.
