Convergence of Monte Carlo distribution estimates from rival samplers

It is often necessary to make sampling-based statistical inference about many probability distributions in parallel. Given a finite computational resource, this article addresses how to optimally divide sampling effort between the samplers of the different distributions. Formally approaching this decision problem requires both the specification of an error criterion to assess how well each group of samples represent their underlying distribution, and a loss function to combine the errors into an overall performance score. For the first part, a new Monte Carlo divergence error criterion based on Jensen–Shannon divergence is proposed. Using results from information theory, approximations are derived for estimating this criterion for each target based on a single run, enabling adaptive sample size choices to be made during sampling.     

An fMRI Study of Responses to Sexual Stimuli as a Function of Gender and Sensation Seeking: A Preliminary Analysis

Although sexual cues produce stronger neural activation in men than in women, mechanisms underlying this differential response are unclear. We examined the relationship of sensation seeking and the brain’s response to sexual stimuli across gender in 27 subjects (14 men, M = 25.2 years, SD = 3.6, 85.2% Caucasian) who underwent functional magnetic resonance imaging (fMRI) while viewing sexual and nonsexual images. Whole-brain corrected significant clusters of regional activation were extracted and associated with gender, sensation seeking, and sexual behaviors. Men responded more to sexual than nonsexual images in the anterior cingulate/medial prefrontal cortex (ACC/mPFC), anterior insula/lateral orbitofrontal cortex, bilateral amygdala, and occipital regions. Sensation seeking related positively to ACC/mPFC (r = 0.65, p = 0.01) and left amygdala (r = 0.66, p = 0.01) response in men alone, with both of these correlations being significantly larger in men than in women (ps < 0.03). The relationship between brain responses and self-reported high-risk and low-risk sexual behaviors showed interesting, albeit nonsignificant, gender-specific trends. These findings suggest the relationship between sexual responsivity, sensation seeking, and sexual behavior is gender specific. This study indicates a need to identify the gender-specific mechanisms that underlie sexual responsivity and behaviors. In addition, it demonstrates that the nature of stimuli used to induce positive mood in imaging and other studies should be carefully considered.     

Changes in Relationship‐Specific Attachment in Emotionally Focused Couple Therapy

Emotionally focused couple therapy (EFT; Johnson, The practice of emotionally focused couple therapy (1st/2nd edition). Brunner‐Routledge, New York, 2004) is an effective treatment of relationship distress (Johnson et al., Clinical Psychology: Science and Practice, 1999; 6, 67). However, less is known about EFT's impact on couples' relationship‐specific attachment bond. Using hierarchical linear modeling with a sample of 32 couples, we examined session‐by‐session changes in couples' relationship‐specific attachment anxiety and avoidance and pre‐ to posttherapy changes in their relationship‐specific attachment behaviors. Couples significantly decreased in relationship‐specific attachment avoidance, and those who completed a blamer softening significantly decreased in relationship‐specific attachment anxiety. Couples' attachment behavior significantly increased toward security. Finally, session‐by‐session decreases in relationship‐specific attachment anxiety and avoidance were significant associated with increases in relationship satisfaction across sessions. These results provide empirical support for the attachment‐based assumptions of EFT. Video abstract accessible by clicking here     

‘I should at least be given a chance to try’: the experience of media workers with disabilities in the United States during postsecondary education and early career

This qualitative study described the lived experience of media workers with disabilities in the United States during postsecondary education and their transition to the professional media workplace. While there is ample literature about disability narratives in media products, there is a significant gap in the research about media workers and students with disabilities. Three participants provided face-to-face interviews and submitted media artifacts that they felt provided abstract representations of their experience. Invariant structural themes that emerged were that participants possessed a high level of self-efficacy, and while their colleges provided supportive environments, they faced discrimination in the media workplace. Additionally, they received few or unhelpful educational accommodations and little guidance from faculty as they transitioned from education to work. Findings suggest a need for faculty training in inclusive pedagogies, review of media curricula that considers students with disabilities, and assistance for students as they progress from postsecondary education to the media workplace.     

Heterosexism,racism, and mental illness discrimination: Experiences of people with mental health conditions and their families

Experiencing discrimination related to race/ethnicity, sexual orientation, or having a mental health condition is associated with negative outcomes. Research comparing types of discrimination or considering intersectionalities is lacking. This study reports findings from interviews with people with mental illnesses (PWMI) or family members of PWMI; all study participants also are of color and/or lesbian, gay, or bisexual. Findings include the following: participants experienced multiple forms of discrimination, mental illness discrimination shares characteristics with racism and heterosexism, and heterosexuals and people of color reported more mental illness discrimination than their counterparts. Implications for change advocates, mental health providers, and researchers are offered.     

The Roles of Instability and Housing in Low-Income Families’ Residential Mobility

Given the repercussions of residential mobility, increased understanding of correlates of mobility is important for efforts to support family well-being. Using survey data on low-income families from the Three City Study (N = 2393), multilevel mixed longitudinal analyses examined factors associated with family residential mobility across the domains of family instability, housing and neighborhood contexts, and family characteristics. Results revealed contributions of family instability and housing and neighborhood contexts to residential mobility, with a higher rate of residential moves associated with experiences of intimate partner violence, relationship transitions, and job transitions, as well as with living in private-market rentals, substandard housing, and disordered neighborhoods. However, owning a home and living in disadvantaged neighborhoods predicted a lower rate of residential moves.     

Competencies for Addressing Gender and Power in Couple Therapy: A Socio Emotional Approach

Power imbalances between partners are intrinsic to relationship distress and intricately connected to emotional experience, couple communication processes, and socio cultural contexts such as gender. The ability to work with the power dynamics between partners is thus critical to the practice of couple therapy. However, few practical guidelines for dealing with this issue are available. The authors present seven clinical competencies regarding gender and power issues that they identified by examining their own work: (a) identify enactments of cultural discourse, (b) attune to underlying socio cultural emotion, (c) name underlying power processes, (d) facilitate relational safety, (e) foster mutual attunement, (f) create a model of equality, and (g) facilitate shared relationship responsibility. Each competency is illustrated through a case example. The competencies represent an over‐arching guide to practice that may be integrated with other clinical approaches and is particularly useful for training and supervision.
