An Examination of Protective Factors for Bisexual Stigma and Alcohol Use among Heavy Drinking Young Bisexual Women.

Bisexual women are an at-risk population for hazardous drinking. One factor contributing to their risk is binegativity (discrimination from heterosexual and lesbian/gay communities). Research has found a positive association between binegativity and alcohol use, but few studies have explored protective factors (bisexual identity affirmation, connectedness to bisexual community) that may buffer this relationship.

A review of empirical treatments focused on mind-body and spiritually grounded complementary practices for moral injury among veterans.

Investigators have called for mind-body practices and spiritual and religious approaches for the treatment of moral injury in veterans. Programs and interventions that use mindfulness, meditation, spirituality, prayer, and other techniques span different academic disciplines and can be difficult for investigators and clinicians to identify but are important for those who work with veterans with moral injury. This paper reports a review of a systematic search that identified 12 empirical studies from eight databases (i.

Bridging electronic and classical density-functional theory using universal machine-learned functional approximations.

The accuracy of density-functional theory (DFT) calculations is ultimately determined by the quality of the underlying approximate functionals, namely the exchange-correlation functional in electronic DFT and the excess functional in the classical DFT formalism of fluids. For both electrons and fluids, the exact functional is highly nonlocal, yet most calculations employ approximate functionals that are semi-local or nonlocal in a limited weighted-density form. Machine-learned (ML) nonlocal density-functional approximations show promise in advancing applications of both electronic and classical DFTs, but so far these two distinct research areas have implemented disparate approaches with limited generality.

Sleep disturbances and psychological well-being among military medical doctors of the Swiss Armed Forces: study protocol, rationale and development of a cross-sectional and longitudinal interventional study.

Background: Compared to civilians and non-medical personnel, military medical doctors are at increased risk for sleep disturbances and impaired psychological well-being. Despite their responsibility and workload, no research has examined sleep disturbances and psychological well-being among the medical doctors (MDs) of the Swiss Armed Forces (SAF). Thus, the aims of the proposed study are (1) to conduct a cross-sectional study (labeled 'Survey-Study 1') of sleep disturbances and psychological well-being among MDs of the SAF; (2) to identify MDs who report sleep disturbances (insomnia severity index >8), along with low psychological well-being such as symptoms of depression, anxiety and stress, but also emotion regulation, concentration, social life, strengths and difficulties, and mental toughness both in the private/professional and military context and (3) to offer those MDs with sleep disturbances an evidence-based and standardized online interventional group program of cognitive behavioral therapy for insomnia (eCBTi) over a time lapse of 6 weeks (labeled 'Intervention-Study 2').

Distal and Proximal Minority Stressors on Patterns of Tobacco and Cannabis Use Among Young Bisexual Women.

Background: Bisexual women have high rates of tobacco and cannabis use, but few studies have examined co-use behavior in this population. Although the role of distal minority stressors (eg, discrimination) on substance use has been examined, fewer studies have examined proximal minority stressors (eg, negative sexual identity self-schemas). The current study was a secondary data analysis that examined patterns of tobacco and cannabis use, and the role of distal (instability of bisexuality, sexual irresponsibility of bisexual people, and hostility toward bisexual people) and proximal (illegitimacy of bisexuality, anticipated binegativity, internalized binegativity, and identity affirmation) bisexual-specific minority stressors among bisexual women.

Fully Ab Initio Approach to Inelastic Atom-Surface Scattering.

We introduce a fully ab initio theory for inelastic scattering of any atom from any surface exciting single phonons, and apply the theory to helium scattering from Nb(100). The key aspect making our approach general is a direct first-principles evaluation of the scattering atom-electron vertex. By correcting misleading results from current state-of-the-art theories, this fully ab initio approach will be critical in guiding and interpreting experiments that adopt next-generation, nondestructive atomic beam scattering.

Normative Perceptions of Sexual Behavior and Alcohol Use among Bisexual Women.

: As compared to heterosexual and lesbian women, bisexual women report higher rates of alcohol, other substance use, and risky sexual behavior, and they experience more negative outcomes from these behaviors. Descriptive norms (i.e.

Impulsivity, sex-related alcohol expectancies, alcohol use, and sexual risk-taking among bisexual women.

Background And Objectives: According to the acquired preparedness model, personality traits, such as impulsivity, may influence the learning process, contributing to heightened expectations surrounding risky behaviors (i.e., alcohol use, sexual risk-taking).

Mindfulness to Manage Moral Injury: Rationale and development of a live online 7-week group intervention for veterans with moral injury.

Background: Military service puts service members at risk for . Moral injury is an array of symptoms (e.g.

Dimensions of binegativity differentially predict drinking to cope motivations and alcohol use severity among bisexual women.

Research indicates that bisexual women experience greater stigmatization and discrimination compared to lesbian women. Such oppression is described as and is associated with alcohol use among bisexual women. Specifically, previous research has suggested that bisexual women may drink to cope in an effort to self-medicate from experiences of binegativity.

A combined helium atom scattering and density-functional theory study of the Nb(100) surface oxide reconstruction: Phonon band structures and vibrational dynamics.

Helium atom scattering and density-functional theory (DFT) are used to characterize the phonon band structure of the (3 × 1)-O surface reconstruction of Nb(100). Innovative DFT calculations comparing surface phonons of bare Nb(100) to those of the oxide surface show increased resonances for the oxide, especially at higher energies. Calculated dispersion curves align well with experimental results and yield atomic displacements to characterize polarizations.

A dyadic examination of alcohol use and intimate partner aggression among women in same-sex relationships.

Despite considerable evidence linking alcohol use and intimate partner aggression among mixed-sex couples, scant research has examined this association in same-sex couples using a dyadic framework. The aim of the present study was to examine associations between one's own and their partner's alcohol use (i.e.

Hookups Among U.S. College Students: Examining the Association Between Hookup Motives and Personal Affect.

"Hooking up" is prevalent on college campuses and is related to both positive and negative outcomes for students. The current study was an exploratory examination of hookup motives, and positive and negative affect, related to the most recent hookup experience. Participants were 256 U.

Examining the added value of harm reduction strategies to emailed boosters to extend the effects of online interventions for college drinkers.

Brief computer-delivered interventions (CDIs) reduce college student drinking and related problems but can be less efficacious and enduring than in-person interventions. The present study examined: (a) the utility of emailed personalized boosters after an evidence-based online CDI for alcohol (i.e.

The role of alcohol demand on daily microaggressions and alcohol use among emerging adult bisexual+ women.

Bisexual women drink more and have more alcohol consequences than heterosexual and lesbian women. This higher risk may in part be attributable to sexual orientation microaggressions. Drinking to cope motivations and alcohol demand may influence the association between microaggressions and alcohol use.

Remote exposure to traumatic events and PTSD symptoms among U.S. Air Force intelligence personnel: Moderating effects of morally injurious experiences.

Objectives: U.S. Air Force (USAF) intelligence, surveillance, and reconnaissance (ISR) personnel continuously view high-resolution, real-time imagery and video feeds that include intermittent exposure to graphic events.

Moral Injury as a Mediator of the Associations Between Sexual Harassment and Mental Health Symptoms and Substance Use Among Women Veterans.

Moral injury is an array of symptoms theorized to develop in response to morally injurious events, defined as events that challenge one's core moral beliefs and expectations about the self, others, and world. Recent measures of moral injury have distinguished self-directed moral injury (e.g.

The role of United States identity in adjustment among Veterans.

Given over 2.77 million US service members have been deployed in the past 20 years and the intense process of reintegration to civilian life, understanding factors that contribute to Veterans' mental health and substance use is critical. This study sought to understand the effects of US identity exploration, US identity commitment, US identity affirmation, and US identity centrality on substance use and symptoms of depression and anxiety.

Rumination as a Mediator of the Associations Between Moral Injury and Mental Health Problems in Combat-Wounded Veterans.

Moral injury is hypothesized to develop from witnessing or engaging in events that violate one's beliefs about themselves and has been shown to be associated with negative mental health symptoms. Although there has been an increase in research examining moral injury among military veterans, mechanisms that link moral injury to mental health outcomes are not well understood. The present study examined rumination subcomponents (problem-focused thoughts, counterfactual thinking, repetitive thoughts, and anticipatory thoughts) as possible mediators of the associations between moral injury (both self-directed and other-directed symptoms) and negative mental health symptoms (i.

A brief history of spaceflight from 1961 to 2020: An analysis of missions and astronaut demographics.

Human spaceflight and the characteristics of people who become astronauts have changed over time. Here we present an analysis of n=1,265 manned spaceflights by n=562 astronauts from 1961-2020 to investigate historical trends over time and between space agencies in terms of astronaut demographics and spaceflight duration. Generalized linear models and generalized linear mixed models were implemented with adjustments for all available demographic data as covariates.

Nitrogen Trapping as a Therapeutic Strategy in Tumors with Mitochondrial Dysfunction.

Under conditions of inherent or induced mitochondrial dysfunction, cancer cells manifest overlapping metabolic phenotypes, suggesting that they may be targeted via a common approach. Here, we use multiple oxidative phosphorylation (OXPHOS)-competent and incompetent cancer cell pairs to demonstrate that treatment with α-ketoglutarate (aKG) esters elicits rapid death of OXPHOS-deficient cancer cells by elevating intracellular aKG concentrations, thereby sequestering nitrogen from aspartate through glutamic-oxaloacetic transaminase 1 (GOT1). Exhaustion of aspartate in these cells resulted in immediate depletion of adenylates, which plays a central role in mediating mTOR inactivation and inhibition of glycolysis.

Genetic deletion of gpr27 alters acylcarnitine metabolism, insulin sensitivity, and glucose homeostasis in zebrafish.

G protein-coupled receptors (GPCRs) comprise the largest group of membrane receptors in eukaryotic genomes and collectively they regulate nearly all cellular processes. Despite the widely recognized importance of this class of proteins, many GPCRs remain understudied. G protein-coupled receptor 27 (Gpr27) is an orphan GPCR that displays high conservation during vertebrate evolution.

Sex differences in predictors of recurrent major depression among current-era military veterans.

Although major depressive disorder (MDD) is a frequent diagnosis among women seeking care in the Veterans Health Administration, little is known about its course. For example, recurrence of MDD and its predictors have been investigated in civilians, but not among female veterans. Because female veterans differ from their civilian counterparts and from male veterans on demographic variables, including race, ethnicity, marital status, and educational level, it is important to identify factors affecting MDD course within this population.

Weekly Drinking and Binge Drinking Mediate the Association Between Drinking Location and Sexual Coercion.

It has been well documented that alcohol use is a risk factor for sexual assault. However, few studies have examined how alcohol use is associated with sexual coercion experiences. Furthermore, off-campus parties and bars are drinking locations where alcohol use is high among college students.
