Early Release Science of the exoplanet WASP-39b with JWST NIRSpec PRISM.

Transmission spectroscopy1-3 of exoplanets has revealed signatures of water vapour, aerosols and alkali metals in a few dozen exoplanet atmospheres4,5. However, these previous inferences with the Hubble and Spitzer Space Telescopes were hindered by the observations' relatively narrow wavelength range and spectral resolving power, which precluded the unambiguous identification of other chemical species-in particular the primary carbon-bearing molecules6,7. Here we report a broad-wavelength 0.5-5.5 µm atmospheric transmission spectrum of WASP-39b8, a 1,200 K, roughly Saturn-mass, Jupiter-radius exoplanet, measured with the JWST NIRSpec's PRISM mode9 as part of the JWST Transiting Exoplanet Community Early Release Science Team Program10-12. We robustly detect several chemical species at high significance, including Na (19σ), H2O (33σ), CO2 (28σ) and CO (7σ). The non-detection of CH4, combined with a strong CO2 feature, favours atmospheric models with a super-solar atmospheric metallicity. An unanticipated absorption feature at 4 µm is best explained by SO2 (2.7σ), which could be a tracer of atmospheric photochemistry. These observations demonstrate JWST's sensitivity to a rich diversity of exoplanet compositions and chemical processes.

This work juxtaposes sociocultural herstories with personal herstories and juxtaposes playfulness and humor with seriousness, frustration, and grief. Ultimately, this piece critically analyzes medical analyses and seeks to recover the body. To view the original version of this poem, see the supplemental material section of this article online.

Collective Healing: A Framework for Building Transformative Collaborations in Public Health.

The capacity of cross-sector collaboration to create meaningful change across social-ecological levels has long been understood in public health. But the ability of cross-sector collaboration to achieve systemic change around the structural determinants of health remains complicated. In 2021, now more than ever, we understand the imperative of strengthening the capacity of collaborative efforts to address the myriad structural health crises facing our communities, from police violence and mass incarceration to Jim Crow laws and redlining, to urban renewal and environmental injustice. Our proposed collective healing framework brings together the collective impact model and radical healing framework to offer a blueprint for cross-sector collaboration that understands the practices of healing to be at the center of public health collaborations and public health practice at large. In this framework, public health practitioners and our collaborators are asked to prioritize relationship building, engage in critical self-reflection, to move beyond compromise, to address differences, to interrogate traditional metrics and approaches, to remake the collective table, and to build shared understanding through action.

Alchemy.

This poem follows the cues of the drumbeat. This poem leaves breadcrumbs. This poem decodes recipes for the writer and the reader. This poem introduces, or rather re-introduces, the onto-epistemology and theory of "conjure feminisms" to public health audiences-Black Feminist ways of being, knowing, and inquiring with attention to nature, memory, the body, one's lineage, and magic making. This poem is an invitation to heal and a re-centering of healing within public health. To view the original version of this poem, see the supplemental material section of this article online.

Using Text Messaging to Improve Access to Prenatal Health Information in Urban African American and Afro-Caribbean Immigrant Pregnant Women: Mixed Methods Analysis of Text4baby Usage.

BACKGROUND: The Text4baby (T4B) mobile health (mHealth) program is acclaimed to provide pregnant women with greater access to prenatal health care, resources, and information. However, little is known about whether urban African American and Afro-Caribbean immigrant pregnant women in the United States are receptive users of innovative health communication methods or of the cultural and systematic barriers that inhibit their behavioral intent to use T4B. OBJECTIVE: This study aimed to understand the lived experiences of urban African American and Afro-Caribbean immigrant pregnant women with accessing quality prenatal health care and health information; to assess usage of mHealth for seeking prenatal health information; and to measure changes in participants' knowledge, perceptions, and behavioral intent to use the T4B mHealth educational intervention. METHODS: An exploratory sequential mixed methods study was conducted among pregnant women and clinical professionals for a phenomenological exploration with focus groups, key informants, interviews, and observations. Qualitative themes were aligned with behavioral and information technology communications theoretical constructs to develop a survey instrument used. repeated-measures pre- and post-test design to evaluate changes in participants' knowledge, attitudes, and beliefs, of mHealth and T4B after a minimum of 4 weeks' exposure to the text message-based intervention. Triangulation and mixing of both qualitative and quantitative data occurred primarily during the survey development and also during final analysis. RESULTS: A total of 9 women participated in phase 1, and 49 patients signed up for T4B and completed a 31-item survey at baseline and again during follow-up. Three themes were identified: (1) patient-provider engagement, (2) social support, and (3) acculturation. With time as a barrier to quality care, inadequate patient-provider engagement left participants feeling indifferent about the prenatal care and information they received in the clinical setting. Of 49 survey participants, 63% (31/49) strongly agreed that T4B would provide them with extra support during their pregnancy. On a Likert scale of 1 to 5, participants' perception of the usefulness of T4B ranked at 4.26, and their perception of the compatibility and relative advantage of using T4B ranked at 4.41 and 4.15, respectively. At follow-up, there was a 14% increase in participants reporting their intent to use T4B and a 28% increase from pretest and posttest in pregnant women strongly agreeing to speak more with their doctor about the information learned through T4B. CONCLUSIONS: Urban African American and Afro-Caribbean immigrant pregnant women in Brooklyn endure a number of social and ecological determinants like low health literacy, income, and language that serve as barriers to accessing quality prenatal health care and information, which negatively impacts prenatal health behaviors and outcomes. Our study indicates a number of systematic, political, and other microsystem-level factors that perpetuate health inequities in our study population.

Adjournment in Community HIV Prevention: Exploring Transitions in Community-Academic Partnerships.

Barbershop-based interventions have been increasingly implemented as a means to support culturally relevant and community-accessible health promotion and disease prevention efforts. Specifically, in neighborhoods of Brooklyn, New York, with high HIV seroprevalence rates, barbers have volunteered to support an initiative to help reduce sexual risk behavior. After implementing the Barbershop Talk With Brothers program for 5 years, we explored how program participation has affected barbers' HIV prevention and counseling skills to promote their clients' health, and assessed their views of next stages of the community-academic partnership, once the specific project ended. Through employing rigorous qualitative research methods with personnel at participating barbershops, key results include that although barbers self-identify as community leaders and even as health educators, they want ongoing support in educating customers about other topics like nutrition and physical activity, including upstream social determinants of health, such as housing and employment. They are also concerned regarding how best to support continuity of efforts and maintenance of partnerships between projects. These findings provide insight toward adjourning community-based participatory research projects, which can inform other academic researchers, organizations, and businesses that partner with community members.

"The hook-up": How youth-serving organizations facilitate network-based social capital for urban youth of color.

Young people of color residing in distressed urban contexts face challenges in accessing social capital that supports positive development and the transition to educational and employment opportunities. Youth-serving organizations play potentially important roles for youth participants to access and leverage networks. This ethnographic study draws on qualitative interviews, conducted with adolescents at a youth-serving organization based in East Oakland, California, to examine how network-based social capital is activated and sustained for and by urban Black and Latinx youth. We found that relationships with supportive adult staff at the organization put youth in contact with caring, trusted adults of color outside of their families who serve as role models for them. These adults provide loving accountability to young people, serving as critical forces in distressed and stigmatized communities. We also found that adult staff activate social leverage to garner various current and future educational and professional opportunities for the youth there. These unique opportunities serve to boost young people's current self-esteem and also to prime them to envision positive futures for themselves. Overall, these findings point to the importance of interpersonal pathways embedded within neighborhood institutions in the activation of network-based social capital.

Stress, Socializing, and Other Motivations for Smoking Among the Lesbian, Gay, Bisexual, Transgender, and Queer Community in New York City.

PURPOSE: This study contributes to the emerging literature on lesbian, gay, bisexual, transgendered, and queer (LGBTQ) health disparities and tobacco use by examining the motivations for smoking among the New York City (NYC) LGBTQ population. APPROACH: We used grounded theory and blended methods from 3 grounded theorists-Strauss, Corbin, and Charmaz-for data collection, coding, and analysis. SETTING: NYC has extensive legislation to prevent smoking; however, the current smoking prevalence of homosexuals is double that of heterosexuals. PARTICIPANTS: Study participants were leaders from 23 NYC LGBTQ organizations. Leaders were chosen to establish a relationship with community and to ensure cultural sensitivity. Eligibility criteria required holding a leadership position in an organization serving the NYC LGBTQ community. METHODS: Interviews were transcribed verbatim and uploaded into Dedoose for analysis. An initial code list was developed from the interview guide. Key themes were identified as the themes with the most number of quotes. RESULTS: Three key themes emerged from our interviews: image, socializing, and stress. Smoking was reported to be a socialization aid and a maladaptive coping technique for stress arising from interactions of conflicting identities. CONCLUSION: Future smoking cessation interventions among the LGBTQ community should equip smokers with healthy coping mechanisms that address the stressors that arise from the intersections of smokers' many identities.

"Wearing My Spiritual Jacket": The Role of Spirituality as a Coping Mechanism Among African American Youth.

There is growing evidence in the theoretical literature regarding the importance of religion and religiosity in people's lives, particularly concerning their health and well-being. Spirituality, a related but different concept, has been less well studied, especially empirically, but shows promise as a mechanism for coping with deleterious social and health circumstances. This article details a qualitative exploration of the role of spiritual coping in the lives of urban African American youth. Data were gathered through in-depth, semistructured interviews with 20 African American youth, ages 12 to 20 years. The findings indicate that urban African American youth have multifaceted dimensions of their spirituality, including the role of prayer in their lives, an unwavering faith in a higher power, and the importance of giving back to their communities. Such findings offer counterstories, generated through ethnographic research, to the dominant discourses regarding urban African American youth. Ultimately, this study's findings have implications for research and practice related to the mechanisms of both ill-health and wellness among youth.

A Comparison of Alternative Tobacco Product Usage, Knowledge and Beliefs Between the New York City Lesbian, Gay, Bisexual, and Transgendered Community and Heterosexuals.

Within the United States, alternative tobacco product (ATP) and varies by geographic region, gender and age. Few articles have been published on the usage of these products among the lesbian, gay, bisexual, transgender or queer (LGBTQ) population. A web-based anonymous survey administered through Google Forms, was used to collect data on current tobacco usage, knowledge and beliefs from adult heterosexuals, homosexuals, bisexuals and transgendered persons residing in New York City from May 2014 to July 2014. Sixty-four individuals completed the survey; 30 were heterosexual and 32 identified as either lesbian, gay, bisexual, transgender or queer. Heterosexuals were found to have tried cigarettes, on average, almost a year before the LGBTQ respondents. Social networks were influential to LGBTQ respondents for an introduction to smoking; 48.00% were introduced by friends, 28.00% by family, 12.00% by a significant other and 9.09% by someone else. For heterosexuals, 73.68% reported that friends introduced them to smoking. More heterosexuals reported trying hookah (N = 10), snus (N = 4) and roll your own cigarettes (N = 5). On average respondents knew of eight different tobacco products, regardless of sexual identity. To our knowledge, we present for the first time a comparison of people who tried, current and former users of ATPs, beliefs and knowledge about ATPs, and sources of knowledge of ATPs by sexual identity from NYC. More research is needed to examine the impact of social networks and the upcoming FDA regulations on ATPs have on the overall prevalence of usage among the LGBTQ community.

"Son of the Soil Daughters of the Land": poetry writing as a strategy of citizen-making for lesbian, gay, and bisexual migrants and asylum seekers in Johannesburg.

South Africa's Constitution, Bill of Rights, and Freedom Charter are globally ground-breaking for providing provisions of non-discrimination, and, of particular note, on the basis of sexual orientation. Since the introduction of these protective frameworks, lesbian, gay, bisexual, transgender, intersex, and queer (LGBTIQ) communities, allies, and advocates in the country have won major legal battles on these issues; however, in spite of these successes, LGBTIQ communities continue to face hostility and violence. As a result, South African LGBTIQ individuals often travel to urban centres, such as Johannesburg, in the hope that these spaces will be more tolerant of their sexual orientation and gender identity; the reality, however, suggests otherwise. Moreover, despite South Africa's designation as a safe haven for LGBTIQ communities, migrants from other African countries - where same-sex relationships are criminalised - are overwhelmingly met with xenophobic verbal, emotional, physical, and political violence. This article describes the authors' engagement with nine lesbian, gay and bisexual (LGB) migrants and asylum seekers from Zimbabwe, Malawi, and elsewhere in South Africa during a weeklong poetry workshop exploring their lived experiences in Johannesburg. This workshop followed a body mapping and narrative writing workshop held previously with the same participants. This article investigates the themes identified from the body mapping process that guided the poems produced: migration, violence, citizenship, and freedom. The poetry created during the workshop illuminates how lesbian, gay, and bisexual migrants in Johannesburg work on a daily basis to build social trust as they demand to be seen and recognised, to enact their rights, to make and remake homes, to show up in public as Black people, as LGB individuals, and as human beings. We explore these strategies of citizen-making as informed by the LGB poets with whom we had the opportunity to work.

"I Want a Second Chance": Experiences of African American Fathers in Reentry.

With over 700,000 people on average released from prison each year to communities, greater attention is warranted on the experiences and needs of those who are parents and seeking to develop healthy relationships with their children and families. This study seeks to explore the experiences of African American fathers in reentry. Qualitative data from 16 African American men enrolled in a fellowship program for fathers were collected from a focus group and analyzed for common themes and using standpoint theory. Four themes emerged that focused on fathers' commitment toward healthy and successful reintegration postincarceration: redemption, employment, health care, and social support. Focus group participants actively strive to develop and rebuild healthy relationships with their children through seeking gainful employment and through bonding with like-minded peers. Barriers in accessing health care are also discussed. Research findings may inform future programs and policies related to supporting fathers and their children in reentry.

Poetic justice: engaging in participatory narrative analysis to find solace in the "killer corridor".

The author engaged with adolescents at a community-based youth organization as "co-researchers" to delve deeper into the lived experiences of youth of color residing in an urban neighborhood undergoing change. Participatory narrative analysis was used to empower participants to produce texts to make sense of their lives and their home, school, and neighborhood contexts. The process of engaging youth as co-researchers and experts in issues pertaining to their own neighborhood is discussed. Nuanced analyses of poems-as-data is shown to be critical in informing the recent surge of interdisciplinary, community-engaged, place-based initiatives focused on neighborhood revitalization, violence prevention, and positive youth development.

Possible climates on terrestrial exoplanets.

What kind of environment may exist on terrestrial planets around other stars? In spite of the lack of direct observations, it may not be premature to speculate on exoplanetary climates, for instance, to optimize future telescopic observations or to assess the probability of habitable worlds. To begin with, climate primarily depends on (i) the atmospheric composition and the volatile inventory; (ii) the incident stellar flux; and (iii) the tidal evolution of the planetary spin, which can notably lock a planet with a permanent night side. The atmospheric composition and mass depends on complex processes, which are difficult to model: origins of volatiles, atmospheric escape, geochemistry, photochemistry, etc. We discuss physical constraints, which can help us to speculate on the possible type of atmosphere, depending on the planet size, its final distance for its star and the star type. Assuming that the atmosphere is known, the possible climates can be explored using global climate models analogous to the ones developed to simulate the Earth as well as the other telluric atmospheres in the solar system. Our experience with Mars, Titan and Venus suggests that realistic climate simulators can be developed by combining components, such as a 'dynamical core', a radiative transfer solver, a parametrization of subgrid-scale turbulence and convection, a thermal ground model and a volatile phase change code. On this basis, we can aspire to build reliable climate predictors for exoplanets. However, whatever the accuracy of the models, predicting the actual climate regime on a specific planet will remain challenging because climate systems are affected by strong positive feedbacks. They can drive planets with very similar forcing and volatile inventory to completely different states. For instance, the coupling among temperature, volatile phase changes and radiative properties results in instabilities, such as runaway glaciations and runaway greenhouse effect.

Identification of developmental disabilities and health problems among individuals under child protective services.

Although a relation between child abuse and developmental disabilities has been established, information about the health and developmental status of children referred to child protective services is not adequately obtained. Case records of 150 children identified to child protective services were reviewed in order to determine the availability of health and developmental information. A screening protocol was developed for the purpose of reviewing case records that has potential for use by child protective services workers.
