Alternative Explanations of Emotional Numbing of Posttraumatic Stress Disorder: An Examination of Hyperarousal and Experiential Avoidance

Abstract: The mechanisms that underlie the emotional numbing symptoms associated with PTSD are not well understood. Studies of Vietnam combat veterans have demonstrated that hyperarousal symptoms predict emotional numbing symptoms more strongly than do other symptoms of PTSD. This study sought to extend these findings through the self-report of 170 female sexual assault survivors. The study also examined whether the relationship between hyperarousal and emotional numbing symptoms was the result of the relationship of each of these to another variable, the tendency to engage in experiential avoidance. Results were consistent with and extended previous findings. Hyperarousal symptoms were also found to predict emotional numbing symptoms above and beyond experiential avoidance, as well as all other symptoms of PTSD.

WiZi-Cloud: Application-transparent dual ZigBee-WiFi radios for low power internet access

Abstract: The high density ofWiFi Access Points and large unlicensed RF bandwidth over which they operate makes them good candidates to alleviate cellular network's limitations. However, maintaining connectivity through WiFi results in depleting the mobile phone's battery in a very short time. We propose WiZi-Cloud, a system that utilizes a dual WiFi-ZigBee radio on mobile phones and Access Points, supported by WiZi-Cloud protocols, to achieve ubiquitous connectivity, high energy efficiency, real time intra-device/inter-AP handover, that is transparent to the applications. WiZi-Cloud runs mostly on commodity hardware such as Android phones and OpenWrt capable access points. Our extensive set of experiments demonstrate that for maintaining connectivity, WiZi-Cloud achieves more than a factor of 11 improvement in energy consumption in comparison with energy-optimized WiFi, and a factor of 7 in comparison with GSM. WiZi-Cloud has a better coverage than WiFi, and a low delay resulting in a good Mean Opinion Score (MOS) of 4.26 for a VoIP US cross-country communication.

Being Transgender Navigating Minority Stressors and Developing Authentic Self-Presentation

Abstract: In this interview-based study, we investigated the common social experiences and minority stressors related to being transgender. It is one of two articles that resulted from a grounded theory analysis of interviews with 17 participants who claimed a variety of transgender identities (e.g., cross-dresser, transman, transwoman, butch lesbian) and were from different regions in the United States. The interview was centered on how participants’ identities influenced their lives across different interpersonal contexts. Participants described developing a more complex understanding of gender because of the effect of their transgender status on others and the need to modify their gender presentation at times to secure their safety. In the workplace, their gender could overshadow their competence and, in the age of social media, was always at risk of becoming public. Seeking social support could be dangerous, and the process of transitioning was found to make safe spaces especially elusive. Also, open communicat...

Youth Initiated Mentoring: Investigating a New Approach to Working with Vulnerable Adolescents

Abstract: This study examines youth initiated mentoring (YIM), a new approach to mentoring in which youth nominate mentors from among the non-parental adults within their existing social networks (e.g., teachers, family friends, extended family members). YIM is currently being implemented through the National Guard Youth ChalleNGe Program (NGYCP), an intensive residential intervention program for youth ages 16–18 who have dropped out or been expelled from high school. This study employed a mixed methods explanatory design, drawing on quantitative data from a national longitudinal evaluation of NGYCP (N = 1,173) and qualitative data from a subsample of participants (N = 30) in the evaluation. Results indicated that more enduring mentoring relationships were associated with increased retention of educational, vocational, and behavioral outcomes 3 years following entry into the study. Qualitative data suggested that, when relationships endured, mentors contributed to improvements in participants’ educational and occupational success, quality of relationships with parents, peers, and others, and self-concept by providing social-emotional support, instrumental support, and guidance. Results also revealed that relationships were more likely to endure when youth chose their mentors on their own (rather than receiving help from parents or program staff) and when mentors were of the same race as youth. Implications for research and practice are discussed.
