Estimation of generalized linear latent variable models

Summary.  Generalized linear latent variable models (GLLVMs), as defined by Bartholomew and Knott, enable modelling of relationships between manifest and latent variables. They extend structural equation modelling techniques, which are powerful tools in the social sciences. However, because of the complexity of the log-likelihood function of a GLLVM, an approximation such as numerical integration must be used for inference. This can limit drastically the number of variables in the model and can lead to biased estimators. We propose a new estimator for the parameters of a GLLVM, based on a Laplace approximation to the likelihood function and which can be computed even for models with a large number of variables. The new estimator can be viewed as an M -estimator, leading to readily available asymptotic properties and correct inference. A simulation study shows its excellent finite sample properties, in particular when compared with a well-established approach such as LISREL. A real data example on the measurement of wealth for the computation of multidimensional inequality is analysed to highlight the importance of the methodology.     

Midwives,Marginality, and Public Identity Work

Because midwifery in the United States is an occupation at the margins of medicine, midwives must frequently negotiate competing identity claims. This article examines the public identity work of a group of midwives by focusing on two important tools they use to accomplish this work: boundary negotiation and impression management. Drawing on data from in‐depth interviews with twenty‐six licensed, nurse, and empirical midwives in the state of Florida, this article illustrates the ways in which midwives frame their identities in relation to history and media representations and manage public identities through boundary negotiation and impression management. I argue that the marginality of this occupation lends itself to competing categories of identity that midwives must negotiate. These categories become salient when midwives confront historical and media representations of childbirth and midwifery as well as the perceptions of the general public, consumers, lawmakers, and medical professionals.     

Individualism vs Collectivism in Different Cultures: A cross-cultural study

In this study, individualism vs collectivism, in line with the work of Triandis in 1985, was assessed in two groups of male and female students, in Egypt and Germany. The results confirm the effect that cultural background has on individualist vs collectivist orientations in both of these cultures for male and female students. Men and women scored higher on individualism in Germany than in Egypt, whereas collectivism scores were higher in Egypt than in Germany. These findings are discussed in terms of general recommendations for intercultural interventions that discourage viewing people solely in terms of group membership, and instead as distinct individuals.     

Understanding Popularity and Relational Aggression in Adolescence: The Role of Social Dominance Orientation

This study investigated a potential moderator of the association between popularity and relational aggression: social dominance orientation (SDO), the degree to which an individual endorses the importance of social hierarchy. One hundred eighty‐five ninth graders completed a sociometric assessment of RA and popularity, and a self‐report SDO measure. SDO was positively associated with popularity for both boys and girls, and with RA for girls. Popularity and RA were positively correlated for both genders. Regression analyses showed that SDO moderated the association between popularity and RA for girls, but not for boys. Girls who were both popular and who were social dominance‐oriented were particularly high in peer‐nominated RA. SDO may provide a useful framework for understanding the role of popularity in adolescent peer groups.     

Social influences on sorority and fraternity member smoking

Objective: To understand how the Greek system uniquely influences smoking attitudes, beliefs, and behaviors among college students who belong to a social sorority or fraternity. Participants: Active members of sororities (n = 16) and fraternities (n = 17) were interviewed between February 2013 and October 2015. Methods: In-depth interviews were conducted examining the social influences of the Greek system on member smoking. Transcribed interviews were coded and analyzed for themes. Results: Sorority and fraternity members experienced different social influences on smoking. Sorority stigmatization of smoking outside bars or parties caused sorority members to hide their smoking. Fraternity members had no social penalties for smoking and allowed smoking at the fraternity house. Fraternity members influenced both fraternity members and sorority members to smoke by sharing cigarettes and smoking at parties. Conclusions: Sororities and fraternities have created social environments that both promote smoking and stigmatize it, presenting unique challenges in college student smoking prevention and cessation efforts.     

Treatment Evaluation in the Presence of Sample Selection

Sample selection and attrition are inherent in a range of treatment evaluation problems such as the estimation of the returns to schooling or training. Conventional estimators tackling selection bias typically rely on restrictive functional form assumptions that are unlikely to hold in reality. This paper shows identification of average and quantile treatment effects in the presence of the double selection problem into (i) a selective subpopulation (e.g., working—selection on unobservables) and (ii) a binary treatment (e.g., training—selection on observables) based on weighting observations by the inverse of a nested propensity score that characterizes either selection probability. Weighting estimators based on parametric propensity score models are applied to female labor market data to estimate the returns to education.     

Égalité entre hommes et femmes et gouvernance des chaînes d'approvisionnement mondiales: promouvoir les droits des travailleuses

La gouvernance privée telle qu'elle découle des différentes initiatives prises par les multinationales pour promouvoir le respect de normes sociales et l'égalité hommes‐femmes a eu peu d'effet sur les discriminations fondées sur le genre dans les chaînes d'approvisionnement mondiales. Les auteures soulignent l'intérêt des Principes directeurs des Nations Unies relatifs aux entreprises et aux droits de l'homme en la matière, estimant qu'il est indispensable de recourir à une gouvernance «stratifiée» associant public, privé et acteurs sociaux pour lutter contre cette discrimination et intégrer le souci de l'égalité des sexes dans l'exercice de la diligence raisonnable exigée en matière de droits de l'homme.     

The ‘new industrial man’ as unhero: Doing postfeminist masculinities in an Italian pharmacological research centre

Recent work has documented the need to engage with how men construct masculinities within postfeminist discourses in the workplace. Postfeminism has sparked debates concerning the changing ideals of masculinities, highlighting the tensions between traditional forms of patriarchy and ‘new’ ways of being a man (e.g., emotional, a ‘new father’, in crisis). Men have been depicted as being in search of a new identity, opposed to the ever‐growing confidence and empowerment of women. In mobilizing postfeminism as a discourse, this article illustrates how men working in an Italian pharmacological research centre (managed by men but dominated by women) assume subject positions that contradictorily fluctuate between tradition and fluid modernity, to reveal a masculinity which we identify with the ‘new industrial man’. The postfeminist masculinities exposed in the analysis mesh pro‐ and anti‐feminist ideas by appealing to un/heroic and romanticized subjectivities. The analysis also shows how un/heroic masculinities and men's appeal to biological differences to reinforce social ones and devalue the feminine obfuscate organizational gender inequalities. The article advances masculinity theory by offering a nuanced analysis of how masculinities and men are affected by paradoxical contemporary pressures for more egalitarian gender relations and a renewed emphasis on patriarchal traditions, which continue to support the gendering of the workplace.
