RESUMO

The present study investigates associations between cumulative police exposures, police violence stress, and depressive symptoms among Black youth, and whether LGBQ (lesbian, gay, bisexual, and queer) identities moderate these associations. Data come from the Survey of Police-Adolescent Contact Experiences (SPACE), a cross-sectional survey of a community-based sample of Black youth ages 12-21 in Baltimore City, Maryland (n = 345), administered from August 2022 to July 2023. We used multivariable ordinary least squares regression to estimate direct associations and product-term analysis to test for effect modification by sexual identities. We also calculate covariate-adjusted predicted depressive symptoms scores by cumulative police exposures and police violence stress across sexual identities. Findings indicate that LGBQ youth collectively reported higher levels of police violence stress than heterosexual youth. Still, LGBQ youth varied in their cumulative police exposures, which were significantly higher among bisexual and queer youth than lesbian or gay youth. Associations between cumulative police exposures, police violence stress, and depressive symptoms were significantly moderated by LGBQ identity, with the largest associations emerging for bisexual and queer youth. Police exposures and police violence stress also compounded to worsen depressive symptoms among the subsample of LGBQ youth. Collectively, our findings suggest that LGBQ youth-especially bisexual and queer youth-may be particularly vulnerable to the mental health harms of cumulative police exposures and police violence stress. Intersectional, public health approaches that combine prevention and treatment strategies are needed to mitigate LGBQ mental health inequities stemming from cumulative police exposures and police violence stress.

RESUMO

Emotion work is a regulatory method used to change the degree or quality of one's own or another's emotions. Among sexual minority people, emotion work is a regulatory method utilised to maximise identity expression while maintaining harmony in interpersonal connections. However, little is known about the utilisation of emotion work among transgender and gender diverse (TGD) people. We sought to address this gap by qualitatively exploring emotion work among members of this population. We conducted semi-structured focus groups and interviews with 11 TGD adults. Eligibility criteria included (1) English speaking, (2) at least 18 years old, (3) currently living in Texas, and (4) identifying as TGD. Interviews explored identity-related experiences of discrimination and affirmation in different social environments, and emotional, physiological and behavioural responses. Interview transcripts were analysed by four researchers using thematic analysis. Four superordinate themes were developed: 1) feeling rules, 2) intrapersonal processes, 3) identity management strategies, and 4) psychophysiological strain. We found transgender and gender diverse participants feel responsible for emotion work to maintain comfort in social interactions often at the expense of authentic identity expression and psychosocial wellbeing. Findings are interpreted using the existing literature on identity management and emotion regulation. Implications for clinical practice are also provided.

RESUMO

INTRODUCTION: In a diverse society, individuals often need to make prosocial decisions toward others who vary on a range of intertwined social identities. Adolescence is a prime time to promote intergroup prosociality due to identity salience during this developmental stage. In this study, our goal was to develop and provide initial validation, of a novel measure on intergroup prosocial behavior considering gender and race/ethnicity. METHOD: We used two independent samples of early adolescents (N1 = 118, Mage = 12.21 years, 55% boys, 59% White collected nationally in the United States.; N2 = 133, Mage = 12.77, 51.1% boys, 77% White collected locally in Arizona). RESULTS: Using the data from Sample 1, Exploratory Factor Analyses revealed a two-factor solution capturing intergroup prosociality and personal distress. Confirmatory Factor Analyses with data from Sample 2 confirmed the factor structure. The reliability of intergroup prosociality was acceptable. Prosociality subscale was positively correlated with adolescents' empathy, sympathy, compliant, emotional, dire, and anonymous prosocial behaviors indicating convergent validity and negatively correlated with adolescents' public prosocial behavior indicating discriminant validity. Further, we examined whether youth engage in differential intergroup prosocial behavior using both variable-centered and person-centered approaches, combining data from Samples 1 and 2. While adolescents did not engage in differential intergroup prosocial behavior, Latent Profile Analyses revealed five distinct profiles of early adolescents' intergroup prosociality. Overall, this study advances research on youth's intergroup prosociality across two intersectional social identities, moving beyond the conceptualization of single social identities in intergroup research.

RESUMO

Social groups and identities significantly influence mental health outcomes, yet their impact in resource-poor communities remains understudied. We explored the role of social group memberships and identities in shaping mental health experiences in two urban poor communities in Ghana. Data from 77 participants were analyzed thematically, revealing widespread engagement in social groups that provide access to both material and symbolic resources. However, these groups also serve as sources of tension and contribute to the stigmatization and marginalization of vulnerable members. Those affected include individuals with severe mental disorders, men experiencing depression, young men involved in substance abuse, family caregivers, migrant and tenant households, and otherwise healthy individuals with recurring psychosocial challenges. The groups exacerbate mental health challenges and restrict access to care among marginalized populations. The findings underscore the need for targeted interventions aimed at enhancing mental health support and reducing stigma in resource-poor settings.

RESUMO

I submit the need to establish a comparative study of societies, namely groups beyond a simple, immediate family that have the potential to endure for generations, whose constituent individuals recognize one another as members, and that maintain control over access to a physical space. This definition, with refinements and ramifications I explore, serves for cross-disciplinary research since it applies not just to nations but to diverse hunter-gatherer and tribal groups with a pedigree that likely traces back to the societies of our common ancestor with the chimpanzees. It also applies to groups among other species for which comparison to humans can be instructive. Notably, it describes societies in terms of shared group identification rather than social interactions. An expansive treatment of the topic is overdue given that the concept of a society (even the use of such synonyms as primate "troop") has fallen out of favor among biologists, resulting in a semantic mess; while sociologists rarely consider societies beyond nations, and social psychologists predominantly focus on ethnicities and other component groups of societies. I examine the relevance of societies across realms of inquiry, discussing the ways member recognition is achieved; how societies compare to other organizational tiers; and their permeability, territoriality, relation to social networks and kinship, and impermanence.We have diverged from our ancestors in generating numerous affiliations within and between societies while straining the expectation of society memberships by assimilating diverse populations. Nevertheless, if, as I propose, societies were the first, and thereafter the primary, groups of prehistory, how we came to register society boundaries may be foundational to all human "groupiness." A discipline-spanning approach to societies should further our understanding of what keeps societies together and what tear them apart.

RESUMO

Little is known about the impact of the COVID-19 pandemic on medical students. We examined medical students' burnout, career regret, and medical school experiences from before to during the pandemic, and differences between students from marginalized and nonmarginalized groups. We analyzed data from 2019 to 2022 Association of American Medical Colleges Year Two Questionnaires (N = 52,152) and Graduation Questionnaires (N = 66,795). Given large samples, we focused on effect sizes versus statistical significance. All effects of study year were less than small (η2 < .01) indicating minimal differences in medical students' burnout, career regret, and school experiences from before (2019) to during (2020-2022) the pandemic. Interactions between study year and demographic characteristics (gender, race-ethnicity, sexual orientation) were less than small; thus, students from marginalized groups were not affected more by the pandemic than others. Across study years, women reported more exhaustion and discrimination than men. Black students reported more discrimination than students from other racial-ethnic groups; bisexual students reported more discrimination than heterosexual students (all ds > 0.20). Differences between students from marginalized and nonmarginalized groups were bigger than the effects of the pandemic, suggesting a need for system-level interventions to foster inclusion in medical education.

RESUMO

Current research on asexual youth is limited, especially in understanding the impact of their outness and the intersection of sexual orientation with gender minority identities. This study investigates the influence of outness on experiences of harassment, discrimination, violence, and the risk of non-suicidal self-injury (NSSI) among asexual youth, with a focus on those with transgender and non-binary identities. Data for this study were obtained from the 2021 Ace Community Survey, an international online survey designed to assess the needs and health status of the Ace community, targeting respondents aged 13 and older. The analysis involved a subsample of 5574 respondents aged 13 to 24 (mean age = 19.28), including 2361 cisgender (mean age = 19.65), 1,195 transgender (mean age = 18.80), and 2,018 non-binary individuals (mean age = 19.13). The results revealed that experienceds of sexual violence, verbal aggression, and physical harassment and bullying not only correlated with but also completely mediated the relationship between outness and NSSI. Asexual transgender youth experienced heightened levels of discrimination and NSSI but demonstrated notable resilience against the negative effects of identity disclosure, highlighting complex dynamics of vulnerability and protection within these communities.

RESUMO

Recent research suggests that two ethnocultural "identities"-such as ethnic identity or national identity-can be compatible (positively correlated) or in conflict (negatively correlated) within and across immigrant-origin groups. In the present article, I advance a more cognitively oriented framework for using correlational patterns to map how immigrant-origin people organize their attachments to a variety of ethnocultural categories. In explaining the value of this framework, I embark on a multistage empirical illustration. First, I perform a correlational class analysis (CCA) using a sample of second-generation Germans and a vector of 13 identity-related indicators. Second, I use a series of linear regressions and a descriptive visualization to clarify the results of my CCA. Third, I fit two multinomial logistic regressions that demonstrate how social attributes-and specifically, religion and ethnicity-impose constraints on the latent schemes that second-generation Germans follow to organize their ethnocultural "identities."

RESUMO

In this paper, we argue that nurses need to be aware of how the production of space in specific contexts - including health care systems and research institutions - perpetuates marginalized populations' state of social otherness. Lefebvre's idea regarding spatial triad is mobilized in this paper, as it pertains to two-spirited, lesbian, gay, bisexual, trans and queer populations (2SLGBTQ*). We believe that nurses can create counter-spaces within health care systems and research institutions that challenge normative discourses. Lefebvre's work provides us the necessary tools to understand how various places or environments produce identities. In understanding Lefebvre's principles, we believe that nurses can play an essential role in creating counter-spaces, thereby instigating counter-institutional practices, for those who experience otherness.

RESUMO

This paper critically analyses three main neurobiological hypotheses on trans* identities: the neurobiological theory about the origin of gender dysphoria, the neurodevelopmental cortical hypothesis, and the alternative hypothesis of self-referential thinking and body perception. In this study I focus then the attention on three elements: the issue of (de)pathologisation, the idea of the trans brain, and the aetiology of trans* identities. While the neurobiological theory about the origin of gender dysphoria and the neurodevelopmental cortical hypothesis claim the existence of the trans brain, each offering its own neurobiological depiction, the hypothesis of self-referential thinking and body perception doesn't postulate a distinctive neurobiological trait for all trans* people. I problematize both portrayals of the trans brain departing from the findings and conceptualizations of the paradigm shifting brain mosaicism. Unlike the hypothesis of self-referential thinking and body perception that keeps the question of causation open, both the neurobiological theory about the origin of gender dysphoria and the neurodevelopmental cortical hypothesis situate the origin of trans* identities in the neurobiological domain. I challenge the biological deterministic framework in which this aetiology is inscribed from a dynamic processual entanglement perspective. Finally, concerning the issue of (de)pathologisation of trans* identities, an evolution can be seen in each of the hypothesis and among them, from the least to the most depathologising. However, I question their complete departure from a pathologising framework.

RESUMO

BACKGROUND: The COVID-19 pandemic continues to spread across the globe and is associated with significant clinical and humanitarian burden. The desire for parenthood has been described to be positively correlated with psychological well-being: An unfulfilled wish for parenthood is associated with impaired mental health, and the wish for parenthood is a predictor for the development of depressive symptoms. While higher rates of anxiety and depression have been reported in individuals with minoritized sexual identities (compared to heterosexual individuals) during the COVID-19 pandemic, the specific impact of the pandemic and its social restriction measures on this population is poorly understood. METHODS: From April to July 2020, we conducted an anonymous cross-sectional survey online among N = 2463 adults living in Germany. We screened for depressive symptoms (Patient Health Questionnaire-4; PHQ-4) and assessed individuals' desire for parenthood during the pandemic, and motives for or against the desire for parenthood (Leipzig questionnaire on motives for having a child, Version 20; LKM-20), with the aim of identifying differences between individuals with minoritized sexual identities and heterosexual individuals. RESULTS: Compared to heterosexual individuals (n = 1304), individuals with minoritized sexual identities (n = 831) indicated higher levels of depressive symptoms. In our study sample the majority of all participants (81.9%) reported no change in the desire for parenthood since the COVID-19 pandemic. CONCLUSION: The findings underline the unmet need for social, psychological and medical support in regard to family-planning and the desire for parenthood during a pandemic. Furthermore, future research should explore COVID-19-related psychological consequences on individuals' desire for parenthood and building a family.

RESUMO

Judgments of physical attractiveness are based on appearance but are influenced by and influence more than just physical features of the face and body (e.g. clothing and personality traits). This is explored in a selective review of previous research, plus new analyses of data from three previously published studies: the Boston Couples Study, the Multiple Identities Questionnaire, and the Intimate Relationships Across Cultures Study, with implications for mental health. Self-ratings of attractiveness are inflated by self-esteem and confidence in self-halo effects. Partner-ratings are inflated by love and relationship satisfaction in partner-halo effects. Positive responses from others influence attractiveness-enhancing cycles, while negative responses influence attractiveness-deprecating cycles, with impacts on well-being. These influences are represented in a comprehensive Attractiveness Halo Model, which identifies Ten Components of Attractiveness that are inter-related, including physical, emotional, sexual, sensory, intellectual, behavioural, observer, situation, reciprocity, and time. Aspects of the model are supported by analyses of the three studies, generalising comprehensive attractiveness halo effects across time, identities, cultures, and relationship types.

RESUMO

Excessive consumption of meat challenges global food security and environmental sustainability. In the mounting literature on identity as a motivator of behaviour, meat consumption has been associated with a handful of identities. Identity theory suggests that people hold multiple identities on different levels of abstraction, but how identities at different levels of abstraction interact and possibly co-determine intentions and behaviour remains largely unanswered. Inspired by research on attitudes and goal hierarchies, this study investigates a hierarchical model of meat-related identities and their relation to intentions to consume red meat. By means of a survey of Danish consumers (N = 1001), we identified identities related to the consumption of red meat (e.g., flexitarian identity), using confirmatory factor analysis and structural equation modelling. We also controlled for the most important additional antecedents identified in prior research. Evidence was found that more abstract identities (e.g., national identity, environmental identity) mostly influence intentions to eat meat indirectly, meditated through more behaviour-specific identities (e.g., flexitarian identity). However, some higher-order identities also appear to have a direct impact on intentions to eat meat after controlling for more behaviour-specific identities, which suggests a less hierarchical structure manifesting itself, possibly due to the behaviour being instrumental at reaching different, functionally unrelated goals that are related to different identities. Policy recommendations towards reducing meat consumption are proposed.

RESUMO

AIMS: To explore ethnic minorities' lived experiences of health-seeking and healthcare utilization in Hong Kong, and to examine the impact of intersectionality of sociocultural identities on intercultural health communication. DESIGN: Qualitative exploratory design. METHODS: Data collection methods were semi-structured interviews, unstructured observations, and unstructured informal group discussions. Twenty-five informants, including eight Pakistanis, seven Nepalese, five Indians, four Bangladeshis and one Sri Lankan, were recruited using the snowball sampling method and individually interviewed between 25th June and 23rd September 2019. RESULTS: Sixteen females and nine males, aged 21-76 years, were in the study. Two-thirds could communicate in English, but eight required interpreters. Thematic analysis reveals four factors affecting intercultural health communication: healthcare professionals' cultural insensitivity, red-tapism and ethnic minorities' language improficiency and/or deficiency in medical knowledge. Health professionals' workplace stress and cultural insensitivity prompt ineffective intercultural communication, making ethnic minority patients feel disrespected despite having adopted the Hong Kong culture. The intersectionality of sociocultural identities plus health professionals' blocking behaviours results in health inequalities. CONCLUSION: The unequal power relationship between health professionals and ethnic minority patients may lead to dehumanizing and depersonalized experiences for patients, as humanity is the heart and soul of medicine. Therefore, the government should raise healthcare providers' cultural sensitivity and diversity awareness, and offer ethno-specific care and more interpretation services. IMPACT: The study addresses health inequalities among Hong Kong ethnic minority patients with different sociocultural identities. About the impact of ineffective intercultural health communication on health inclusion and health outcomes, policies and practices should ameliorate health professionals' cultural sensitivity, awareness of the unequal power relationship and respect for diversity. PATIENT OR PUBLIC CONTRIBUTION: Referred by organizations serving ethnic minorities, the minority patients shared their lived experiences in health-seeking.

RESUMO

BACKGROUND: Physicians' values about what constitute their professional identities are integral in understanding how they ascribe meaning to their practice. However, there is no general consensus on the conceptualization and measurement of physicians' professional identities. This study developed and validated a values-based scale for measuring physicians' professional identities. METHODS: A hybrid research method was used to gather both qualitative and quantitative data. We employed literature review, semi-structured interview, Q-sorting exercise to examine the conceptualization of emergency physicians' professional identities and to initially develop a 40-item scale. A panel of five experts assessed the scale's content validity. Using 150 emergency physicians as our sample, we conducted Confirmatory Factor Analyses (CFA) to test the fit of our hypothesised four-factor model based on our preliminary findings. RESULTS: Initial CFA suggested revisions to the model. Following theoretical assumptions and modification indices, the model was revised and adjusted to a four-factor 20 item Emergency Physicians Professional Identities Value Scale (EPPIVS) with acceptable fit statistics χ2 = 389.38, df = 164, Normed χ2 = 2.374, GFI = 0.788, CFI = 0.862, RMSEA = 0.096. The Cronbach's alpha, McDonald's Omega reliability and composite reliability of the subscales ranged from α: 0.748 to 0.868, Omega: 0.759 to 0.868 and CR: 0.748 to 0.851, respectively. CONCLUSION: The results indicate that the EPPIVS is a valid and reliable scale for measuring physicians' professional identities. Further research on the sensitivity of this instrument to important changes over career progression in emergency medicine is warranted.

RESUMO

This paper explores how Indigenous-led research reframes the impacts and response to environmental disasters in the context of acid mine spills in rural communities of the Southwest United States. The collaborative research project addressing the Gold King Mine Spill (GKMS) designed qualitative methodologies that center Indigenous worldviews and contribute to broader understandings of environmental justice. The research team, led by Diné scholars and community leaders, gathered qualitative responses from 123 adult participants in twelve focus groups from three rural communities on the Navajo Nation. The project incorporated fluent Diné speakers and cultural consultants to lead focus groups in a manner consistent with cultural worldviews. The analysis of the focus group data resulted in original findings that reframe previous understandings of environmental harm by broadening the boundaries to include: 1) social relations across time; 2) social relations across space; 3) spiritual relations; and 4) restoring balance. The findings allow for greater insight into the colonial context of disaster on rural and Indigenous lands and confronts colonial-rooted disasters through Indigenous-informed political action.

RESUMO

Understanding what groups stand for is integral to a diverse array of social processes, ranging from understanding political conflicts to organisational behaviour to promoting public health behaviours. Traditionally, researchers rely on self-report methods such as interviews and surveys to assess groups' collective self-understandings. Here, we demonstrate the value of using naturally occurring online textual data to map the similarities and differences between real-world groups' collective self-understandings. We use machine learning algorithms to assess similarities between 15 diverse online groups' linguistic style, and then use multidimensional scaling to map the groups in two-dimensonal space (N=1,779,098 Reddit comments). We then use agglomerative and k-means clustering techniques to assess how the 15 groups cluster, finding there are four behaviourally distinct group types - vocational, collective action (comprising political and ethnic/religious identities), relational and stigmatised groups, with stigmatised groups having a less distinctive behavioural profile than the other group types. Study 2 is a secondary data analysis where we find strong relationships between the coordinates of each group in multidimensional space and the groups' values. In Study 3, we demonstrate how this approach can be used to track the development of groups' collective self-understandings over time. Using transgender Reddit data (N= 1,095,620 comments) as a proof-of-concept, we track the gradual politicisation of the transgender group over the past decade. The automaticity of this methodology renders it advantageous for monitoring multiple online groups simultaneously. This approach has implications for both governmental agencies and social researchers more generally. Future research avenues and applications are discussed.

RESUMO

In this paper, we present the derivation of Jeffreys divergence, generalized Fisher divergence, and the corresponding De Bruijn identities for space-time random field. First, we establish the connection between Jeffreys divergence and generalized Fisher information of a single space-time random field with respect to time and space variables. Furthermore, we obtain the Jeffreys divergence between two space-time random fields obtained by different parameters under the same Fokker-Planck equations. Then, the identities between the partial derivatives of the Jeffreys divergence with respect to space-time variables and the generalized Fisher divergence are found, also known as the De Bruijn identities. Later, at the end of the paper, we present three examples of the Fokker-Planck equations on space-time random fields, identify their density functions, and derive the Jeffreys divergence, generalized Fisher information, generalized Fisher divergence, and their corresponding De Bruijn identities.

RESUMO

How are immigrant academic mothers negotiating the confounding terrains of work and family during the pandemic? How can they support each other in learning how to resist the prevalent notions of ideal working and mothering amidst the demanding schedule of working remotely and parenting? This study addresses these questions through sharing a narrative of how two immigrant mothers in academia challenged and began the journey of transforming their gendered work and family identities. Building on personal essays and 6 weeks of extensive journaling that reflected our positionalities and experiences of motherhood, work-life, and intersections between work and home during the pandemic, we offer a fine-grained understanding of how we helped each other as co-mentors to identify moments of our lived experiences as triggers for transformative learning. In doing so, we realized how duoethnography could be more than just a research methodology in helping us co-construct a relational space to empathize and challenge each other's perspectives about our roles as mothers and professors and the gendered nature of social forces shaping those roles.

RESUMO

BACKGROUND: African yam bean (Sphenostylis stenocarpa) is an underutilized crop that has the potential to contribute to sustainable food security. In October 2021, more than 90% African Yam Bean (AYB) plants showed typical virus symptoms of mosaic and necrosis in the grain legumes field of the Institute of Agricultural Research and Training (IAR&T), Nigeria. METHODS AND RESULTS: Subsequently, leaf samples were collected and tested by ELISA and PCR to identify the virus species. Anti-BCMV and anti-potyvirus antibodies both gave positive results when symptomatic leaves were tested, and PCR using primers designed to the coat protein gene of BCMV amplified a band of the expected size (469 bp). The sequence of the PCR product was deposited in GenBank with the accession No. OL763314. The nucleotide sequence of the coat protein gene had 99% identity with BCMV isolate TN2 (KY044818). The identities of the nucleotide and amino acid sequence of the partial CP gene of the isolated virus relative to those of other potyviruses were 82.96-99.12% and 87.33-100%,, respectively. Phylogenetic analyses of the partial CP-nucleotide sequences grouped the isolate from this study (BCMV-IART-AYB) and BCMV-TN2 in the same cluster with other BCMV strains of the peanut stripe (PSt) and the blackeye cowpea (BlC) strains. CONCLUSIONS: In this study, we identified Bean commom mosaic virus (BCMV) infecting AYB for the first time in Nigeria and show that it has high nucleotide and amino acid identity with an Isolate of cowpea-infecting BCMV in India and China respectively than isolate in Nigeria.
