Emerging Genetic and Epigenetic Mechanisms Underlying Pubertal Maturation in Adolescence

The adolescent transition begins with the onset of puberty which, upstream in the brain, is initiated by the gonadotropin‐releasing hormone (GnRH) pulse generator that activates the release of peripheral sex hormones. Substantial research in human and animal models has revealed a myriad of cellular networks and heritable genes that control the GnRH pulse generator allowing the individual to begin the process of reproductive competence and sexual maturation. Here, we review the latest knowledge in neuroendocrine pubertal research with emphasis on genetic and epigenetic mechanisms underlying the pubertal transition.

Clinical and Ethical Considerations for Delivering Couple and Family Therapy via Telehealth

Studies have generally supported telehealth as a feasible, effective, and safe alternative to in‐office visits. Telehealth may also be of particular benefit to couples/families interested in relational treatments, as it addresses some of the barriers that may be more prominent for families, such as childcare and scheduling difficulties. Therapists interested in expanding their practice to include telehealth should understand ethical and practical considerations of this modality. This article discusses areas unique to the delivery of telehealth to couples and families. Each broad domain is then elaborated upon with case examples from actual clinical practice and specific recommendations for addressing potential difficulties. Authors recommend further empirical research examining differences in modality outcome, as well as feasibility of the suggestions proposed here.     

The Mediating Effect of Resilience Between Social Support for Exercise and Resident Satisfaction in Assisted Living

This study examined whether residents' level of resilience mediated the relationship between social support for exercise from staff and resident satisfaction in assisted living. This was a secondary data analysis using baseline data from a function-focused care intervention study including 171 residents from four assisted living facilities. Using structural equation modeling, we found that mood and social support for exercise from staff were the only variables associated with resilience. Mood, gender, cognition, and social support for exercise from staff directly influenced resident satisfaction and explained 31% of the variance in the model. Implications for future research and practice are discussed.     

Bioecological Implications of Narrative Exposure Therapy in Low‐Resource Settings: Individual,Family, Community,and Socio‐Political Contexts

Traumatic stress can have detrimental effects on individuals, families, and communities. Narrative exposure therapy (NET) is an evidence‐based intervention for decreasing individuals’ post‐traumatic stress disorder (PTSD) symptoms and has been tested in some of the most challenging contexts, such as in post‐conflict refugee camps. Although the focus of NET is on reducing individual PTSD symptoms, the impact of NET can be seen beyond the individual level. The purpose of this paper is to examine some of the ecological implications of using NET with trauma‐affected populations in low‐resource settings. We describe the implications of NET at the family, community, and sociopolitical levels using several case examples. Finally, we outline limitations and future directions for improving the delivery of NET in settings with limited resources.     

The echo chamber is overstated: the moderating effect of political interest and diverse media

ABSTRACT

In a high-choice media environment, there are fears that individuals will select media and content that reinforce their existing beliefs and lead to segregation based on interest and/or partisanship. This could lead to partisan echo chambers among those who are politically interested and could contribute to a growing gap in knowledge between those who are politically interested and those who are not. However, the high-choice environment also allows individuals, including those who are politically interested, to consume a wide variety of media, which could lead them to more diverse content and perspectives. This study examines the relationship between political interest as well as media diversity and being caught in an echo chamber (measured by five different variables). Using a nationally representative survey of adult internet users in the United Kingdom (N?=?2000), we find that those who are interested in politics and those with diverse media diets tend to avoid echo chambers. This work challenges the impact of echo chambers and tempers fears of partisan segregation since only a small segment of the population are likely to find themselves in an echo chamber. We argue that single media studies and studies which use narrow definitions and measurements of being in an echo chamber are flawed because they do not test the theory in the realistic context of a multiple media environment.     

Blood,Sweat, and Tears: Navigating Creepy versus Cool in Wearable Biotech

ABSTRACT

This paper considers how personal data protections figure into the design process of wearable technology. The data question is becoming especially important in the face of recent innovations in biotechnology that capitalize on the new fungibility of biology and electronics, in which new biotech wearables capitalize on the ability to analyze and track changes in blood, sweat, and tears. Interviews and participant observation with wearable tech designers, data scientists, fashion tech entrepreneurs, and select experts in cybersecurity and intellectual property law, reveal a range of approaches to data protection in design within the culture where wearables are beginning to merge with biotech. While a few respondents were extremely vigilant about protecting consumer’s privacy, the majority felt that when consumers ‘opt in’ to data sharing, they should be cognizant of the risks. From their perspective, it is not necessarily the producer’s responsibility to protect user's personal data. These attitudes present a problematic logic, which leaves users vulnerable to data exploitation. The paper concludes by arguing that this laissez-faire culture is the environment in which wearable biotech is being developed and will be deployed. This emerging technology raises issues about bodies, data, and ownership in crucial need of analysis and critique to push its move into the mainstream toward more equitable and inclusive ends.     

Deciphering blog users: young adults’ personalities,motivations, and perceived importance of blog features

The present study examines the cyberpsychology of blog readership as well as the digital content preferences of the Millennial generation by examining the links between college students’ personality traits, motivations to read blogs, and preferred blog features. Results indicate that personality influences motivations for reading blogs, which in turn helps predict perceived importance of blog characteristics. Notably, extraversion and neuroticism were related to reading blogs for social interaction; extraversion negatively predicted use of blogs to meet identity needs; openness was related to blog reading for entertainment purposes; and conscientiousness was positively associated with information seeking via blogs. Additionally, motivations for blog readership as explanatory mechanisms for the relationships found between personality traits and perceived importance of blog features are discussed.     

Patterns of Intimate Partner Violence and Sexual Risk Behavior among Young Heterosexually Active Men

Intimate partner violence (IPV) victimization is linked to sexual risk exposure among women. However, less is known about the intersection of IPV perpetration and sexual risk behavior among men. This study used data from a diverse, community sample of 334 heterosexually active young men, aged 18 to 25, across the United States to examine whether and how men with distinct IPV-related behavior patterns differed in sexual risk–related behavior and attitudes. Participants were recruited and surveyed online, and grouped conceptually based on the types of IPV perpetration behavior(s) used in a current or recent romantic relationship. Groups were then compared on relevant sexual risk variables. Men reporting both physical abuse and sexual coercion against intimate partners reported significantly higher numbers of lifetime partners, higher rates of nonmonogamy, greater endorsement of nonmonogamy, and less frequent condom use relative to nonabusive men or those reporting controlling behavior only. This group also had higher sexually transmitted infection (STI) exposure compared to men who used controlling behavior only and men who used sexual coercion only. Findings suggest that interventions with men who use physical and sexual violence need to account for not only the physical and psychological harm of this behavior but also the sexual risk to which men may expose their partners.
