Objective: To evaluate a personalized adaptive training program designed for stress prevention using graduated stress exposure.

Background: Astronauts in the high-risk space mission environment are prone to performance-impairing stress responses, making preemptive stress inoculation essential for their training.

Methods: This work developed an adaptive virtual reality-based system that adjusts environmental stressors based on real-time stress indicators to optimize training stress levels. Sixty-five healthy subjects underwent task training in one of three groups: skill-only (no stressors), fixed-graduated (prescheduled stressor changes), and adaptive. Psychological (subjective stress, task engagement, distress, worry, anxiety, and workload) and physiological (heart rate, heart rate variability, blood pressure, and electrodermal activity) responses were measured.

Results: The adaptive condition showed a significant decrease in heart rate and a decreasing trend in heart rate variability ratio, with no changes in the other training conditions. Distress showed a decreasing trend for the graduated and adaptive conditions. Task engagement showed a significant increase for adaptive and a significant decrease for the graduated condition. All training conditions showed a significant decrease in worry and anxiety and a significant increase in the other heart rate variability metrics.

Conclusion: Although all training conditions mitigated some stress, the preponderance of trial effects for the adaptive condition supports that it is more successful at decreasing stress.

Application: The integration of real-time personalized stress exposure within a VR-based training program not only prepares individuals for high-stress situations by preemptively mitigating stress but also customizes stressor levels to the crew member's current state, potentially enhancing resilience to future stressors.

Being trans is stigmatized and can make it difficult to fit into the job market in South Korean society. This study explored trans individuals' job-seeking experience and the impact of gender identity on their career choices and development using a qualitative approach. In-depth interviews were conducted with 20 trans adults with job-seeking experiences who were recruited through purposive and snowball sampling in South Korea. Ten subthemes were identified in three overarching themes: (a) limiting myself in job search; (b) challenges in the job application and interview process; and (c) having a desire to build a meaningful career. Participants limited their choices for employment in favor of gender-neutral jobs or trans-inclusive work environments. In the job-seeking process, they faced challenges due to society's rigid binary gender roles and the negative stereotypes about trans identities. Despite stress and identity-related conflict, participants expressed a desire to overcome challenges, build a meaningful career, and flourish at work without compromising their gender identity. This study highlights the experiences of trans individuals in their job-seeking journey. Psychosocial interventions and career support services could help trans individuals in the job-seeking process by identifying their unique challenges to employment and providing assistance to cope with stigma and oppression.

The study aims at assessing gender and sexuality characteristics (GSC) in perception, attitude, and social intimacy among Sinophone youth toward transgender and gender non-conforming (TGNC) people. Based on an internet survey with 3 825 valid questionnaires, we distinguished the general public into TGNC, cisgender heterosexual, and cisgender non-heterosexual individuals. Then we classified TGNC individuals into trans females, trans males, and non-binary/genderqueer people and cisgender individuals into cisgender females and cisgender males. The chi-square test, one-way analysis of variance (ANOVA), and multiple linear regression were used. We found that the evident gender and sexuality disparities in perception, attitude, and social intimacy toward TGNC individuals exist both in and out of TGNC individuals. Negative perceptions and attitudes as well as alienated social intimacy were most pronounced among cisgender heterosexual people (Chi-square test, one-way ANOVA, and multiple linear regression: all p < .001). Cisgender females exhibit higher levels of supportiveness compared to cisgender males. Trans females were the most positive while they also had more concerns regarding public space and gender expression-related issues. The findings are practical for community-based advocacy for raising public awareness of the presences and experiences of TGNC people in Sinophone societies.

Little research has examined factors, such as emotion regulation strategies, that amplify or mitigate associations between discrimination and tobacco use among sexual minority young adults (SMYAs). SM-identifying YA (ages 18-34) women (N = 450; M_age = 24.11; 31.1% racial or ethnic minority) and men (N = 254; M_age = 24.68; 28.0% racial or ethnic minority) residing in 6 US metropolitan areas were surveyed. Bivariate analyses examined associations of sociodemographics (i.e. age, race, ethnicity, education), discrimination, and emotion regulation strategies (i.e. cognitive reappraisal, expressive suppression) with tobacco use outcomes (i.e. past 30-day cigarette, e-cigarette, other tobacco [aggregated across cigars, hookah] use). Multivariable logistic regressions were built for each tobacco use outcome and included sociodemographic covariates, discrimination and emotion regulation strategies, and interactions between discrimination and emotion regulation strategies. Among SMYA women, a significant interaction of discrimination and cognitive reappraisal indicated that discrimination was associated with greater odds of past 30-day e-cigarette use only among women with lower levels of cognitive reappraisal. Discrimination and emotion regulation were not significantly associated with tobacco use among men. SMYA women with lesser use of cognitive reappraisal may be at heightened risk for e-cigarette use if they experience discrimination. Tobacco cessation programs for SM women should incorporate emotion regulation skills.

This qualitative research uses a case study to observe non-binary representation in TV fiction. The Dan character from the Spanish series HIT (RTVE, 2020-present), who is the first openly non-binary character in Spanish TV fiction, is analyzed through the lens of Queer Media Studies. The research applies a combination of content and discourse analysis. Qualitative content categories include a character's visibility, identity, relevance, embodiment, and social interaction. Discourse analysis categories include character's construction, lexicalization, propositional framing, and focus. Results show that Dan's non-binary depiction revolves around three significant axes: dualism, confusion, and exceptional talent. These axes frame social attitudes toward non-binary people and are composed by a set of features identified in Dan's case which also informs society's mind-sets. These traits are proposed as an analytical-theoretical tool for further analyses of non-binary representation in different cultural contexts. The outcomes of this research may inform audiovisual industries, regulations and academia, and are useful to consolidate non-binary media studies.

Individuals who identify as a sexual minority, including those who are lesbian, gay, or bisexual (LGB), face barriers to healthcare as well as increased discrimination, stigmatization, and negative experiences during healthcare use. Further, few healthcare providers have education and training focused on the specific healthcare needs of individuals who are part of a sexual minority group. Given the limited research on Canadian healthcare access for sexual minorities, our purpose was to use data (n > 2,800) from the 2015-16 Canadian Community Health Survey (CCHS) to investigate the perceptions of healthcare access for LGB and non-LGB Canadians. Although non-LGB and LGB participants reported comparable access to a regular care provider and were equally likely to have consulted with a general practitioner in the past 12 months, LGB respondents were more likely to have seen a specialist and reported more unmet health needs. Although we expected the linear effects of both race and sex to vary by LGB status, this effect only occurred in one model. Current results have implications for addressing health inequalities for sexual minorities, including poorer health outcomes and greater discrimination.

The aim of the present study was to assess the psychometric properties of a Swedish translation of the Sexual Orientation Microaggressions Scale (SOMS) in a convenience sample of 267 Swedish LGB+ people (Mean age = 36.41). Testing suggested some strengths in terms of factor structure and 2-week test-retest reliability (ICC > .79). Also, internal consistency (α = .80-.91) and convergent validity were supported for most subscales. However, the Assumption of Deviance subscale was associated with low response variability and internal consistency (α = .35), and the correlational pattern between the Environmental Microaggressions subscale and mental health variables diverged from the overall trend. Furthermore, measurement invariance between homo- and bisexual participants was not supported for most subscales, and although microaggressions would be theoretically irrelevant to a small comparison sample of heterosexual people (N = 76, Mean age = 40.43), metric invariance of the Environmental Microaggressions subscale was supported in comparison to LGB+ people. We argue that these limitations suggest a restricted applicability of the SOMS in a Swedish context, and this has consequences for the definition and operationalization of the construct of microaggressions as a whole. Therefore, more research on the latent properties of microaggressions in Swedish as well as in other contexts is required.

Grindr is a popular geospatial networking application (GSNA) among gay, bisexual, and men who have sex with men (GBMSM); it can be used for variety of goals (e.g. finding dates, making friends, or coordinating a hookup) depending on the user's wants. These needs and wants, however, do not arise in a vacuum. Informed by uses and gratification (U&G) theory, this paper examined individual factors such as race, body image and depression as drivers of the motivations behind Grindr usage In an online cross-sectional survey (N = 102), we explored the antecedents of six different motivations (i.e. friendship, sex, entertainment, romantic partnership, social inclusion, and location-based community) for Grindr use among GBMSM. The results revealed that romance and friendship motives increased Grindr usage compared to the other four motivation categories. Across motivation categories, habitual Grindr usage was a significant driver of continued Grindr use. Individual factors such as race, sociosexuality and self-disclosure also influenced users' motivations to use Grindr. Overall, the results point to individual factors eliciting differing motivations for Grindr use, resulting in either outcome-based or passive usage of the application.

The COVID-19 pandemic has led to faster digitalization and illegal online gambling has become popular. As illegal online gambling brings not only financial threats but also breaches in overall cyber security, this study defines the concept of absolute illegal online gambling (AIOG) using a machine-learning-driven approach with information gathered from public webpages. By analysing 11,172 sites to detect illegal online gambling, the proposed model classifies key features such as URLs (Uniform Resource Locator), WHOIS, INDEX, and landing page information. With a combination of text and image analyses with machine learning-driven approach, the proposed model offers the ensemble combination of attributes for high detection performance with the verification of common attributes from metadata in online gambling. This study suggests a strategy for dynamic resource utilization to increase the classification accuracy of the current environment. As a result, this research expands the scope of hybrid web mining through constant updating of data to achieve content-based filtering.

Gambling and substance use disorders (SUDs) are prevalent among U.S. military veterans and often co-occur. However, little is known about the clinical and behavioral correlates and suicidal risk of SUDs and gambling among veterans that can help inform targeted interventions for their co-occurrence. In the current study, we analyzed data from a nationally representative sample of 4069 veterans who participated in the National Health and Resilience in Veterans Study. Self-reported measures of lifetime SUDs and past-year gambling (Brief Problem Gambling Screen) were administered. A multinomial logistic regression analysis was conducted to examine differences between four groups: non-SUD/non-gambling, 40.3%; SUD-only 27.3%; Gambling-only 16.3%; and SUD + Gambling, 16.1%. The Gambling-only, SUD-only, and SUD + Gambling groups reported more adverse childhood experiences relative to the non-SUD/non-gambling group. The SUD-only and SUD + Gambling groups had higher odds for all lifetime and current clinical and trauma variables relative to the non-SUD/non-gambling group. The SUD + Gambling group had higher odds of suicidality, non-suicidal self-injury, nicotine dependence and mental health treatment relative to the SUD-only group and all assessed clinical measures relative to the Gambling-only group. Results suggest that SUDs and gambling are associated with substantial trauma and mental health burden among U.S. veterans, with co-occurring SUDs and gambling linked particularly to suicidality/self-harm and mental health treatment. The findings underscore the importance of multicomponent assessments and interventions targeting SUDs, gambling, and related concerns, such as trauma-related mental health difficulties, in this population.
