Social Factors, Alcohol Expectancy, and Drinking Behavior: A Comparison of Two College Campuses
Background: Though college students have high rates of heavy drinking, few studies have examined the various pathways through which risks affect drinking and whether this varies by institution. We examined whether alcohol expectancy mediates the relationship between social factors (i.e., hooking up, friends drinking, Greek affiliation, entitlement) and drinking behavior comparing college students from one Midwestern and one Southeastern university. Methods: In the 2013â14 academic year, 1,482 college students (51% female) enrolled in undergraduate courses at two public universities completed a paper and pencil survey of attitudes and experiences about dating, sexuality, and substance use. Multiple group path analysis was used to compare two institutions. Results: Drinking behavior was positively associated with hooking up more often, Greek affiliation, being male, having close friends who consume more alcohol, and greater alcohol expectancies. We found unique differences in the mediating pathways for the two campuses. Conclusion: This study provides a more nuanced understanding of risk factors for heavy drinking. Moreover, it adds to the scarce body of literature concerning entitlement and drinking and the unique pathways between two college campuses. Finally, the results could lead to the development of more specific intervention strategies to reduce risky drinking among U.S. college students
The Role of Protective Behavioral Strategies, Social Environment, and Housing Type on Heavy Drinking among College Students
Background: Though research has examined heavy drinking by housing type, the link between type of college student housing and protective behavioral strategies (PBS) has rarely been examined comparing different college campuses. Objectives: The purpose of this study is to examine the role of housing type, perceptions of peer drinking, and PBS with respondent heavy drinking among undergraduate college students from one Southeastern and one Midwestern university in the United States. Methods: 1,448 college students enrolled in undergraduate courses at two public universities completed a paper and pencil survey of attitudes and experiences about dating, sexuality, and substance use. Data were analyzed using multiple group path analysis. Results: Students living in Greek housing perceived their close friends as engaging in more risky drinking and had higher rates of heavy drinking compared to those living in other housing types. The effect of perceptions of peer drinking on PBS was significantly different between campuses, as were several other indirect pathways to heavy drinking. Conclusion/Importance: Understanding more about the differing roles of college residential environments can help inform effective drinking interventions and reduce heavy drinking among college students

Incorporating Mental Health Research into Disaster Risk Reduction: An Online Training Module for the Hazards and Disaster Workforce
There is an expansive and growing body of literature that examines the mental health consequences of disasters and large-scale emergencies. There is a need, however, for more explicit incorporation of mental health research into disaster risk reduction practices. Training and education programs can serve as a bridge to connect academic mental health research and the work of disaster risk reduction practitioners. This article describes the development and evaluation of one such intervention, the CONVERGE Disaster Mental Health Training Module, which provides users from diverse academic and professional backgrounds with foundational knowledge on disaster mental health risk factors, mental health outcomes, and psychosocial well-being research. Moreover, the module helps bridge the gap between research and practice by describing methods used to study disaster mental health, showcasing examples of evidence-based programs and tools, and providing recommendations for future research. Since its initial release on 8 October 2019, 317 trainees from 12 countries have completed the Disaster Mental Health Training Module. All trainees completed a pre- and post-training questionnaire regarding their disaster mental health knowledge, skills, and attitudes. Wilcoxon Signed Rank tests demonstrated a significant increase in all three measures after completion of the training module. Students, emerging researchers or practitioners, and trainees with a high school/GED education level experienced the greatest benefit from the module, with Kruskal–Wallis results indicating significant differences in changes in knowledge and skills across the groups. This evaluation research highlights the effectiveness of the Disaster Mental Health Training Module in increasing knowledge, skills, and attitudes among trainees. This article concludes with a discussion of how this training can support workforce development and ultimately contribute to broader disaster risk reduction efforts.

The date the article was first made available online will be carried over.The majority of adults in the UK and US are overweight or obese due to multiple factors including excess energy intake. Training people to inhibit simple motor responses (key presses) to high-energy density food pictures reduces intake in laboratory studies. We examined whether online response inhibition training reduced real-world food consumption and weight in a community sample of adults who were predominantly overweight or obese (N = 83). Participants were allocated in a randomised, double-blind design to receive four 10-minute sessions of either active or control go/no-go training in which either high-energy density snack foods (active) or non-food stimuli (control) were associated with no-go signals. Participantsâ weight, energy intake (calculated from 24-hour food diaries), daily snacking frequency and subjective food evaluations were measured for one week pre- and post-intervention. Participants also provided self-reported weight and monthly snacking frequency at pre-intervention screening, and one month and six months after completing the study. Participants in the active relative to control condition showed significant weight loss, reductions in daily energy intake and a reduction in rated liking of high-energy density (no-go) foods from the pre- to post-intervention week. There were no changes in self-reported daily snacking frequency. At longer-term follow-up, the active group showed significant reductions in self-reported weight at six months, whilst both groups reported significantly less snacking at one- and six-months. Excellent rates of adherence (97%) and positive feedback about the training suggest that this intervention is acceptable and has the potential to improve public health by reducing energy intake and overweight.National Institute for Health and Research Exeter Clinical Research FacilityWellcome TrustEuropean Research Counci
Deep Late-Time Observations of the Supernova Impostors SN 1954J and SN 1961V
SN 1954J in NGC 2403 and SN 1961V in NGC 1058 were two luminous transients whose definitive classification as either non-terminal eruptions or supernovae remains elusive. A critical question is whether a surviving star can be significantly obscured by dust formed from material ejected during the transient. We use three lines of argument to show that the candidate surviving stars are not significantly optically extinct (Ï âČ 1) by dust formed in the transients. First, we use SED fits to new HST optical and near-IR photometry. Secondly, neither source is becoming brighter as required by absorption from an expanding shell of ejected material. Thirdly, the ejecta masses implied by the Hα luminosities are too low to produce significant dust absorption. The latter two arguments hold independent of the dust properties. The Hα fluxes should also be declining with time as tâ»Âł, and this seems not to be observed. As a result, it seems unlikely that recently formed dust can be responsible for the present faintness of the sources compared to their progenitors, although this can be verified with the James Webb Space Telescope. This leaves three possibilities: (1) the survivors were misidentified; (2) they are intrinsically less luminous; (3) SN 1954J and SN 1961V were true supernovae
Contestable adulthood: variability and disparity in markers for negotiating the transition to adulthood
Recent research has identified a discreet set of subjective markers that are seen as characterizing the transition to adulthood. The current study challenges this coherence by examining the disparity and variability in young peopleâs selection of such criteria. Four sentence-completion cues corresponding to four differentcontexts in which adult status might be contested were given to 156 British 16- to 17-year-olds. Their qualitative responses were analyzed to
explore patterns whilst capturing some of their richness and diversity. An astonishing amount of variability emerged, both within and between cued contexts.The implications of this variability for how the transition to adulthood is experienced are explored. The argument is made that markers of the transition to adulthood are not merely reflective of the bioâpsychoâsocial development of
young people. Rather, adulthood here is seen as an essentially contested concept,located within the discursive interactional environment in which young people participate
Adherence to the updated guidelines for the prevention of perinatal Group B streptococcal disease
In 2010, the Centers for Disease Control and Prevention updated the Guidelines for the Prevention of Perinatal Group B Streptococcal (GBS) Disease. Previous studies of adherence to GBS guidelines have focused on the treatment of carriers of GBS. Our objective was to determine whether there was any difference in adherence to the guidelines for screening and treatment of women who delivered at our institution between the beginning of 2011 and the end of 2011 as the revised guidelines were published in November 2010. Our secondary outcome was to determine whether any differences in adherence occurred between prenatal provider types (OB/Gyn, Certified Nurse Midwives, and Family Practice)

Proton radiotherapy for chest wall and regional lymphatic radiation; dose comparisons and treatment delivery
Purpose The delivery of post-mastectomy radiation therapy (PMRT) can be challenging for patients with left sided breast cancer that have undergone mastectomy. This study investigates the use of protons for PMRT in selected patients with unfavorable cardiac anatomy. We also report the first clinical application of protons for these patients. Methods and materials Eleven patients were planned with protons, partially wide tangent photon fields (PWTF), and photon/electron (P/E) fields. Plans were generated with the goal of achieving 95% coverage of target volumes while maximally sparing cardiac and pulmonary structures. In addition, we report on two patients with unfavorable cardiac anatomy and IMN involvement that were treated with a mix of proton and standard radiation. Results: PWTF, P/E, and proton plans were generated and compared. Reasonable target volume coverage was achieved with PWTF and P/E fields, but proton therapy achieved superior coverage with a more homogeneous plan. Substantial cardiac and pulmonary sparing was achieved with proton therapy as compared to PWTF and P/E. In the two clinical cases, the delivery of proton radiation with a 7.2 to 9 Gy photon and electron component was feasible and well tolerated. Akimbo positioning was necessary for gantry clearance for one patient; the other was treated on a breast board with standard positioning (arms above her head). LAO field arrangement was used for both patients. Erythema and fatigue were the only noted side effects. Conclusions: Proton RT enables delivery of radiation to the chest wall and regional lymphatics, including the IMN, without compromise of coverage and with improved sparing of surrounding normal structures. This treatment is feasible, however, optimal patient set up may vary and field size is limited without multiple fields/matching
