Explicit Verbal Sexual Consent Communication: Effects of Gender,Relationship Status,and Type of Sexual Behavior

Objectives: College students believe that they are supposed to be explicit and verbal in their sexual consent communication. We examined various contexts to determine when sexual consent is likely to be communicated explicitly and verbally. Method: We surveyed U.S. college students’ (n?=?707) sexual consent communication. Results: We identified contexts when explicit verbal consent cues are less likely—when the person is a woman, when the sexual relationship is casual, and when the sexual behavior is not vaginal-penile intercourse. Conclusions: If sexual consent is contextual, that means communicating consent should not ever be taken for granted.     

Predictors of Posttraumatic Stress and Growth Among Black and White Survivors of Hurricane Katrina: Does Perceived Quality of the Governmental Response Matter?

Data from the Baseline Survey of the Hurricane Katrina Community Advisory Group Study (Kessler 2009) were used to explore the predictors of posttraumatic growth and posttraumatic stress among black (n?=?265) and white (n?=?715) adult survivors of Hurricane Katrina. We focus on the perceived quality of the governmental response and cognitive processing related to the response on posttraumatic outcomes, and whether there were racial group differences. We also consider the impact of demographic factors and severity of stress. Results of hierarchical linear regression showed that being black, older, having lower educational attainment, and experiencing greater perceived stress and loss during Katrina positively predicted greater posttraumatic growth. Being female, living below the poverty line, and experiencing greater perceived stress and loss positively predicted posttraumatic stress symptoms. More positive views of the governmental response were associated with greater posttraumatic growth and more negative views with greater posttraumatic stress symptomology. Moreover, it was found that race significantly moderated the effect between perceived quality of the response and posttraumatic stress. Subgroup analysis corroborated the interaction effect and showed that while perceived quality of the governmental response significantly predicted posttraumatic stress for black survivors, it was not a significant predictor for white survivors. This study sheds light on some of the factors and conditions under which positive and negative post-trauma outcomes occurred after Katrina. We propose that racial group differences in the impact of perceived quality of the response on posttraumatic stress may be related to views among some black survivors that the emergency response was discriminatory.     

The rhetoric and reality of youth mentoring

Enduring and supportive mentoring relationships can powerfully influence the course and quality of adolescent lives. As mentoring continues to expand, community agencies are implementing alternatives to the traditional one-on-one mentoring mode. Such efforts may help to reach youth who might otherwise fall through the cracks.     

Testing the efficacy of the theory of planned behavior to explain strength training in older adults

The purpose of this study was to use the constructs of the theory of planned behavior (TPB) to gain a better understanding of the factors influencing older adults' participation in strength training. Two hundred men and women age 55 years and older were purposely sampled from seniors' centers in Ontario Canada. Participants completed a TPB questionnaire and reported their current physical activity participation. It was hypothesized that perceived behavioral control followed by attitude would be the strongest determinants of strength-training intentions and that intention would be the strongest determinant of strength-training behavior. Regression analyses revealed that subjective norm and perceived behavioral control explained 42% of the variance in intention and intention explained 40% of the variance in behavior. Gender and current strength-training participation did not significantly moderate the relationship between the TPB variables. The results suggest that interventions targeting subjective norm and perceived control might be helpful in promoting strength-training behavior among older adults.     

Parameter identifiability in a class of random graph mixture models

We prove identifiability of parameters for a broad class of random graph mixture models. These models are characterized by a partition of the set of graph nodes into latent (unobservable) groups. The connectivities between nodes are independent random variables when conditioned on the groups of the nodes being connected. In the binary random graph case, in which edges are either present or absent, these models are known as stochastic blockmodels and have been widely used in the social sciences and, more recently, in biology. Their generalizations to weighted random graphs, either in parametric or non-parametric form, are also of interest. Despite these many applications, the parameter identifiability issue for such models has only been touched upon in the literature. We give here a thorough investigation of this problem. Our work also has consequences for parameter estimation. In particular, the estimation procedure proposed by Frank and Harary for binary affiliation models is revisited in this article.     

Transactional Sex and Preferences for Pre-Exposure Prophylaxis (PrEP) Administration Modalities Among Men Who Have Sex With Men (MSM)

Pre-exposure prophylaxis (PrEP) is an important biomedical human immunodeficiency virus (HIV) prevention tool gaining more popularity among Parisian men who have sex with men (MSM) who engage in transactional sex. This study examines the knowledge of, and willingness to use, different modalities of PrEP among this subgroup. Broadcast advertisements were placed on a geosocial-networking smartphone application with a link to a Web-based survey during three 24-hour periods in October 2016. Modified Poisson regression models were used to assess the association between engagement in transactional sex and preferences for each of these PrEP modalities. A total of 444 respondents were included. About 14% reported engagement in transactional sex. In all, 90% of MSM who engaged in transactional sex were knowledgeable of daily oral PrEP, while 13.3% were knowledgeable about long-acting injectable PrEP or penile or rectal microbicides. They were more likely to be aware of long-acting injectable PrEP (aRR = 2.52, 95% CI = 1.16 to 5.47) and willing to use daily oral PrEP (aRR = 1.48; 95% CI = 1.11 to 1.98) or long-acting injectable PrEP (aRR = 1.40; 95% CI = 1.09 to 1.81) than MSM who had not engaged in transactional sex. Long-acting injectable PrEP may be an important HIV-prevention option for MSM who engage in transactional sex if this modality is proven effective.     

How Family Therapy Stole My Interiority and Was Then Rescued by Open Dialogue

This paper serves as a naive autoethnography, based on the effect of open dialogue training on my practice as a systemic family therapist. It follows a beginner's attempt at a newly recognised form of writing, one that reflects the messy, emergent links between people, voices, experiences, sensations, memories, theories, objects, friends, and other entities, one that is also, however, actually in my head and body and real, territorialised in place, cities, streets, and rooms. It is an autoethnography in that it serves as a narrated introspection, built on a barometric research machine that will be described.
