"I tried to appreciate it in a different way": Older lesbian, bisexual, and queer women's body image and embodiment across the life course.

We examined the life histories of older lesbian, bisexual, and queer women, focusing on the stories they told about their bodies and sexuality from early to later life. Guided by a narrative constructionist approach, a series of two life history interviews were conducted with 17 lesbian, bisexual, and queer women aged 65-86. Two themes were constructed through a narrative thematic analysis: Queering the Corset: Negotiating Gender Expression and (Aspirational) Aging Body Acceptance. Participants experienced body-related freedom through 'tomboy' expressions of physicality as children. This body autonomy was constrained in adolescence and adulthood due to heterosexist messages surrounding idealized femininity relayed by family and (heterosexual) men, which disrupted self-care yet catalyzed attuned, queer desire and positive embodiment. Women worked to accept their bodies as they aged; they experienced some body dissatisfaction in relation to age-related body changes, yet gratitude and pride in their older queer identities. The findings highlight concurrent positive and negative body image, and breadth of body-related experiences ranging from attunement and agency to discomfort and disruption throughout the life course. This work contributes to body image and embodiment research by moving beyond dominant (youthful) heteronormative perspectives by illuminating how ageism and heterosexism can shape body-related experiences.

A reinforcement learning approach to airfoil shape optimization.

Shape optimization is an indispensable step in any aerodynamic design. However, the inherent complexity and non-linearity associated with fluid mechanics as well as the high-dimensional design space intrinsic to such problems make airfoil shape optimization a challenging task. Current approaches relying on gradient-based or gradient-free optimizers are data-inefficient in that they do not leverage accumulated knowledge, and are computationally expensive when integrating Computational Fluid Dynamics (CFD) simulation tools. Supervised learning approaches have addressed these limitations but are constrained by user-provided data. Reinforcement learning (RL) provides a data-driven approach bearing generative capabilities. We formulate the airfoil design as a Markov decision process (MDP) and investigate a Deep Reinforcement Learning (DRL) approach to airfoil shape optimization. A custom RL environment is developed allowing the agent to successively modify the shape of an initially provided 2D airfoil and to observe the associated changes in aerodynamic metrics such as lift-to-drag (L/D), lift coefficient (Cl) and drag coefficient (Cd). The learning abilities of the DRL agent are demonstrated through various experiments in which the agent's objective-maximizing L/D, maximizing Cl or minimizing Cd-as well as the initial airfoil shape are varied. Results show that the DRL agent is able to generate high performing airfoils within a limited number of learning iterations. The strong resemblance between the artificially produced shapes and those found in the literature highlights the rationality of the decision-making policy learned by the agent. Overall, the presented approach demonstrates the relevance of DRL to airfoil shape optimization and brings forward a successful application of DRL to a physics-based aerodynamics problem.

Non-binary reproduction: Stories of conception, pregnancy, and birth.

Background: Many non-binary individuals AFAB (assigned female at birth) seek gestational parenthood. However, the limited available literature is often focused on trans men and overlooks the conception, pregnancy, and birth experiences of non-binary parents. Aims: The study aimed to capture the unique reproduction narratives of non-binary people AFAB. Methods: Five non-binary individuals volunteered to participate in this study. Data were collected using largely unstructured, in-depth, tape-recorded interviews. Thematic analysis of the verbatim transcripts and tape recordings yielded a chronological, cohesive narrative for each participant. Four participants reviewed their narrative and confirmed that their story was accurately represented. The individual narratives were then woven into one collective narrative, and common themes across the participants' stories were identified. Results: Before conception, most participants considered how to balance their medical and social transitions with their reproductive goals. Conception was relatively easy and straightforward for the four participants who used their partner's sperm. The gendered nature of, and language surrounding, pregnancy greatly impacted participant's reproductive experiences, leading to feelings of isolation and loneliness, difficulties finding maternity clothes and gender dysphoria. Participants desired gender-affirming care and reported mostly positive experiences with their healthcare providers. Their gender identity influenced their experiences of parenthood, as well as the decisions they made regarding the disclosure of their gender identity to others, their gender presentation, chestfeeding, and parental designations. Discussion: The cisnormative and heteronormative scripts that surround pregnancy shaped the reproductive narratives of those who participated in this research. The findings reinforce the importance of inclusive, gender-affirming healthcare and social support services.

Sexual Function, Quality of Life, and Experiences of Women with Ovarian Cancer: A Mixed-Methods Study.

INTRODUCTION: Ovarian cancer impacts approximately 1 in 75 women. Sexual health is receiving increasing attention as a critical aspect of gynecologic cancer treatment and a component of quality of life. Therefore, investigating how women with ovarian cancer experience and express sexuality is an important area of inquiry. AIMS: To evaluate how women with ovarian cancer experience and express sexuality, a major determinant of quality of life, in the context of their illness. METHODS: In a mixed-methods approach, 6 validated self-report questionnaires (n = 64) and an in-depth focus group (n = 3) were used to gather data. RESULTS: The quantitative phase of the study showed that women with ovarian cancer have a poorer quality of life and higher rates of sexual dysfunction and sexual distress compared with published norms from the general population. They also have lower levels of relationship satisfaction and increased rates of depression. The qualitative phase of the study revealed 6 themes: (i) changes to relationship satisfaction; (ii) sexual difficulties; (iii) challenges with body image; (iv) gaps in communication with healthcare providers; (v) feelings of guilt, grief, resentment, anxiety, and fear; and (vi) strategies used for coping. CONCLUSIONS: Ovarian cancer impacts women's lives beyond mere survival, including their sexual function and quality of life. Healthcare providers are urged to prepare women with ovarian cancer for these challenges and offer information and resources to help improve their quality of life and sexuality.
