Interventions for Problem and Pathological Gambling: Status, Innovations, and Challenges

The purpose of this presentation is to address research on the effectiveness of problem gambling interventions and offer insights for new directions. Dr. Martens has led two clinical trials over the past five years that have integrated technology into problem gambling interventions for young adults. In the first trial (Martens et al., 2015), he found that a computerized personalized feedback intervention reduced gambling problems among at-risk young adult gamblers. In the second trial (Martens et al., in preparation), he found that an intervention delivered via cell phone and text-message had an indirect effect on gambling-related problems. Although effect sizes for these interventions were in the small to medium range, both interventions were relatively inexpensive and easy to implement. He will discuss these findings, how they fit into the context of prior brief intervention efforts in the field (e.g., Cunningham et al., 2009; Hodgins et al., 2009; Petry et al., 2008), how they may be able to scale up and be disseminated widely, and how they inform potential future directions for reducing problem gambling among young adults and other vulnerable populations. He will also address some of the unique challenges associated with integrating technology into brief intervention efforts

Technology-Based Brief Interventions for At-Risk Young Adult Gamblers

The purpose of this presentation to discuss my work developing and evaluating the efficacy of brief interventions designed to reduce at-risk gambling and related negative consequences among young adults. Research has established that young adults, especially college students, are more likely to meet classification for “disordered” gambling than the general adult population (Blinn et al., 2007). Brief interventions that incorporate personalized feedback have been shown to be efficacious at motivating behavior change among young adults (Cronce & Larimer, 2011). The purpose of this presentation will be to discuss my efforts at extending this work to the area of at-risk gambling. Over the past 3 years our laboratory has conducted two clinical trials examining the efficacy of personalized feedback-based interventions among college students who exceeded a threshold for at-risk gambling. In the first trial we found that participants in a personalized-feedback condition delivered via computer reported fewer dollars wagered and fewer gambling-related problems than those in the control conditions (Martens et al., 2015). Follow-up analyses examining mediators and moderators of intervention effects will also be discussed. In the second trial, which is currently ongoing, we are examining the efficacy of delivering intervention content via smartphone. Participants in the intervention condition receive personalized feedback on their phone, and then receive subsequent follow-up text messages that contain either personalized feedback or general educational information about gambling. Preliminary findings regarding the efficacy of these interventions will be discussed, as will implications of the findings for promoting responsible gambling among young adults

Examining the Efficacy of a Brief Group Protective Behavioral Strategies Skills Training Alcohol Intervention With College Women

College students’ use of protective behavioral strategies (PBS; e.g., determining not to exceed a set number of drinks, avoiding drinking games) is related to lower levels of alcohol consumption and problems. The present study evaluated the efficacy of a novel brief, single-session group PBS skills training intervention aimed at increasing college students’ use of PBS and reducing risky drinking and consequences. Participants (N = 226) were heavy-drinking incoming first-year college women randomized to either a PBS skills training intervention or study skills control condition. Participants attended a 45-min group session and completed online surveys pre- and postintervention (1 month and 6 months). We conducted a series of 2 × 2 × 3 repeated-measures ANCOVAs with condition and baseline mental health (anxiety/depression) as the between-subjects factors and time as the within-subjects factor. Intervention participants, relative to controls, reported significantly greater increases in PBS use and reductions in both heavy episodic drinking and alcohol consequences. The intervention was particularly effective in increasing PBS use at 1 month among participants with high anxiety. Further, tests of moderated mediation showed a significant conditional indirect effect of condition on 1-month consequences through PBS use among participants with high levels of anxiety. Findings provide preliminary support for a brief PBS-specific group intervention to reduce alcohol risk among college women, particularly anxious women. Future research is needed to strengthen the long-term effectiveness of the present approach and further explore the moderating effects of mental health

\u3ci\u3eIshtarella thailandica\u3c/i\u3e Martens, new genus, new species (Hymenoptera: Braconidae: Aphidiinae) of aphid parasitoid from Thailand, with a country checklist of Aphidiinae

Ishtarella Martens new genus (Hymenoptera: Braconidae: Aphidiinae) and I. thailandica Martens new species are described and illustrated from Doi Phu Kha National Park, Nan Province, Thailand. The genus is assigned to the tribe Aphidiini, subtribe Trioxina. Based on morphology, Ishtarella appears most closely related to Binodoxys Mackauer. An updated checklist of the aphidiine fauna of Thailand, based on published records, is presented. Parasitoid wasps in the subfamily Aphidiinae (Hymenoptera: Braconidae) comprise about 60 genera and more than 650 species worldwide (Yu et al. 2016). The Aphidiinae of Thailand were all but unknown prior to a Thai­land Inventory Group for Entomological Research (TIGER) project from 2006–2009 (Starý et al. 2008). As part of the TIGER project the Thai aphidiine fauna was surveyed using Malaise and pan traps; 20 species collectively representing 15 genera were reported from mixed deciduous or pine forests from 230 m to 2500 m above sea level (Starý et al. 2008, 2010a, 2010b). Although there are no identification keys to the Thai Aphidiinae, genus-level identifications can be made using the keys presented in Starý and Schlinger (1967), Starý and Ghosh (1983), Raychaudhuri (1990), and Chen and Shi (2001). The new genus described herein is assigned to the tribe Aphidiini, subtribe Trioxina. Females of most genera in this subtribe possess an elongate and curved ovipositor sheath and ovipositor. Additionally, females of some genera, like Binodoxys Mackauer and Trioxys Haliday, possess distinctive hypopygial prongs that are used to hold and restrain the aphid host during oviposition (Völkl and Mackauer 2000)

Student service members/veterans on campus: Challenges for reintegration.

Many returning OIF/OEF/OND Veterans are seeking higher education in an effort to develop a meaningful career and financial stability. Evidence suggests that student service members/ veterans (SSM/Vs) are experiencing less academic success than other students. The purpose of this review is to identify the unique challenges of SSM/Vs and evaluate current campus efforts to facilitate their retention and academic performance. With a focus on SSM/Vs attending colleges and universities, we obtained 57 peer-reviewed and 73 gray literature records published between 2001 and 2015. The current SSM/V literature contains an abundance of gray literature, and the empirical research tends to be limited by cross-sectional design and small sample sizes. SSM/Vs encounter significant personal and environmental challenges when transitioning from the military to college campuses. A variety of services have been developed to address the needs of the SSM/V population, but the efficacy of these services remains largely unknown. In conclusion, there is a clear need to provide education to faculty, students, and staff regarding the experiences of SSM/Vs. Efforts to enhance screening for, availability of, and SSM/V engagement in mental health services would also be beneficial, as would improved availability of and SSM/V access to academic support. All future programs designed to address the unique challenges of SSM/Vs in the academic environment should also be systematically implemented and evaluated

Steady-state modulation of voltage-gated K+ channels in rat arterial smooth muscle by cyclic AMP-dependent protein kinase and protein phosphatase 2B

Voltage-gated potassium channels (Kv) are important regulators of membrane potential in vascular smooth muscle cells, which is integral to controlling intracellular Ca2+ concentration and regulating vascular tone. Previous work indicates that Kv channels can be modulated by receptor-driven alterations of cyclic AMP-dependent protein kinase (PKA) activity. Here, we demonstrate that Kv channel activity is maintained by tonic activity of PKA. Whole-cell recording was used to assess the effect of manipulating PKA signalling on Kv and ATP-dependent K+ channels of rat mesenteric artery smooth muscle cells. Application of PKA inhibitors, KT5720 or H89, caused a significant inhibition of Kv currents. Tonic PKA-mediated activation of Kv appears maximal as application of isoprenaline (a β-adrenoceptor agonist) or dibutyryl-cAMP failed to enhance Kv currents. We also show that this modulation of Kv by PKA can be reversed by protein phosphatase 2B/calcineurin (PP2B). PKA-dependent inhibition of Kv by KT5720 can be abrogated by pre-treatment with the PP2B inhibitor cyclosporin A, or inclusion of a PP2B auto-inhibitory peptide in the pipette solution. Finally, we demonstrate that tonic PKA-mediated modulation of Kv requires intact caveolae. Pre-treatment of the cells with methyl-β-cyclodextrin to deplete cellular cholesterol, or adding caveolin-scaffolding domain peptide to the pipette solution to disrupt caveolae-dependent signalling each attenuated PKA-mediated modulation of the Kv current. These findings highlight a novel, caveolae-dependent, tonic modulatory role of PKA on Kv channels providing new insight into mechanisms and the potential for pharmacological manipulation of vascular tone

The state of the Martian climate

60°N was +2.0°C, relative to the 1981–2010 average value (Fig. 5.1). This marks a new high for the record. The average annual surface air temperature (SAT) anomaly for 2016 for land stations north of starting in 1900, and is a significant increase over the previous highest value of +1.2°C, which was observed in 2007, 2011, and 2015. Average global annual temperatures also showed record values in 2015 and 2016. Currently, the Arctic is warming at more than twice the rate of lower latitudes
