Social adversity in pregnancy and trajectories of women’s depressive symptoms: A longitudinal study

Background

Sound evidence has linked the experience of adversity with depression. Less is known about this association over time.

‘Let’s hope the Boston Marathon Bomber is a White American’: racialising Muslims and the politics of white identity

This paper examines public discourse on race, whiteness and Muslims through an in-depth exploration of an online media controversy following the 2013 Boston Marathon bombings. On 16 April, the day after the attacks, the liberal magazine Salon.com published David Sirota’s article, ‘Let’s Hope the Boston Marathon Bomber is a White American’. A firestorm of commentary followed, with conservatives defending the profiling of Muslims, and accusing Sirota of anti-white racism. Anchored in questions of race, racism and Muslims and marked by a sharp partisan polarisation, these discussions intensified after 18 April, when the Tsarnaev brothers were identified as the perpetrators. The ensuing debate surrounding the racial identity of the Tsarnaevs displays how Muslim racialisation occurs and operates within a conservative discourse strongly committed to a colour-blind ideology. Our paper moves beyond this affirmation of literature on Muslim racialisation and sets this process within a relationally constructed and performative white racial identity.     

Non‐parametric Copula Estimation Under Bivariate Censoring

In this paper, we consider non‐parametric copula inference under bivariate censoring. Based on an estimator of the joint cumulative distribution function, we define a discrete and two smooth estimators of the copula. The construction that we propose is valid for a large range of estimators of the distribution function and therefore for a large range of bivariate censoring frameworks. Under some conditions on the tails of the distributions, the weak convergence of the corresponding copula processes is obtained in l^∞([0,1]²). We derive the uniform convergence rates of the copula density estimators deduced from our smooth copula estimators. Investigation of the practical behaviour of these estimators is performed through a simulation study and two real data applications, corresponding to different censoring settings. We use our non‐parametric estimators to define a goodness‐of‐fit procedure for parametric copula models. A new bootstrap scheme is proposed to compute the critical values.     

College students' multiple stereotypes of lesbians: A cognitive perspective

This paper examines stereotypes of lesbians held by college students. Multiple stereotypes are elicited from a free response trait listing task, followed by a sorting task. The results of the sorting task are submitted to cluster analysis and multidimensional scaling to reveal the complexity of cognitive representations of this group. Eight types are described, reflecting underlying distinctions between positive perceptions (e.g., lipstick lesbian, career-oriented feminist) and negative perceptions (e.g., sexually deviant, angry butch) and also between relative strength and weakness. The research is discussed in terms of cognitive perspectives on stereotyping and gender inversion theory. Suggestions for future research are provided.     

Self-organizing maps in population based metaheuristic to the dynamic vehicle routing problem

We consider the dynamic vehicle routing problem (dynamic VRP). In this problem, new customer demands are received along the day. Hence, they must be serviced at their locations by a set of vehicles in real time. The approach to address the problem is a hybrid method which manipulates the self-organizing map (SOM) neural network into a population based evolutionary algorithm. The method, called memetic SOM, illustrates how the concept of intermediate structure, also called elastic net or adaptive mesh concept, provided by the original SOM can naturally be applied into a dynamic setting. The experiments show that the heuristic outperforms the approaches that were applied to the Kilby et al. 22 problems with up to 385 customers. It performs better with respect to solution quality than the ant colony algorithm MACS-VRPTW, a genetic algorithm, and a multi-agent oriented approach, with a computation time used roughly 100 times lesser.     

Single-index regression models with right-censored responses

In this article, we propose some new generalizations of M-estimation procedures for single-index regression models in presence of randomly right-censored responses. We derive consistency and asymptotic normality of our estimates. The results are proved in order to be adapted to a wide range of techniques used in a censored regression framework (e.g. synthetic data or weighted least squares). As in the uncensored case, the estimator of the single-index parameter is seen to have the same asymptotic behavior as in a fully parametric scheme. We compare these new estimators with those based on the average derivative technique of Lu and Burke [2005. Censored multiple regression by the method of average derivatives. J. Multivariate Anal. 95, 182–205] through a simulation study.     

Evaluating theory-based evaluation: information, norms, and adherence

Programmatic social interventions attempt to produce appropriate social-norm-guided behavior in an open environment. A marriage of applicable psychological theory, appropriate program evaluation theory, and outcome of evaluations of specific social interventions assures the acquisition of cumulative theory and the production of successful social interventions - the marriage permits us to advance knowledge by making use of both success and failures. We briefly review well-established principles within the field of program evaluation, well-established processes involved in changing social norms and social-norm adherence, the outcome of several program evaluations focusing on smoking prevention, pro-environmental behavior, and rape prevention and, using the principle of learning from our failures, examine why these programs often do not perform as expected. Finally, we discuss the promise of learning from our collective experiences to develop a cumulative science of program evaluation and to improve the performance of extant and future interventions.     

“Parenting Is Not a Job … It’s a Relationship”: Recognition and Relational Knowledge Among Parents of Gender Non-conforming Children

Parents of gender non-conforming children encounter substantial conflict as they negotiate their children’s “Otherness.” For decades, a pathologizing service model has advocated clinical correction. In opposition, some parents adopt affirming stances toward their children. This study explored the knowledge underneath this stance, asking parents of gender non-conforming children how they know what they know. Analysis revealed a process of recognition and knowledge of the children’s needs acquired through relationship. Drawing on political philosophy and psychoanalytic theory, I argue that the affirming approach to gender non-conforming children is a non-aggressive response to the “Other” and a justice-based parenting practice.
