Different Categorizations of Women's Sexual Orientation Reveal Unique Health Outcomes in a Nationally Representative U.S. Sample.

Background: Sexual minority women (i.e., women minoritized for their sexualities) are identified as high risk for mental health and substance use problems; however, there is no consensus on the criteria by which women are categorized as sexual minority.

Missing perspective: Marginalized groups in the social psychological study of social disparities.

Drawing on interdisciplinary, feminist insights, we encourage social psychologists to embrace the active participation of marginalized groups in social disparities research. We explain (1) how the absence of marginalized groups' perspectives in research presents a serious challenge to understanding intergroup dynamics and concomitant disparities, and (2) how their inclusion could assuage some of social psychology's "fatal flaws."

Femininity Concerns and Feelings About Menstruation Cessation Among Lesbian, Bisexual, and Heterosexual Women: Implications for Menopause.

Women differ in how they psychologically respond to the end of menstruation and onset of menopause; however, little empirical evidence exists for understanding how sexual orientation and gendered dynamics contribute to menstrual experiences in middle-to-late adulthood. We investigated if women's attitudes toward the cessation of menstruation vary by their sexual orientation. Using data from the Midlife in the United States Study (MIDUS,  = 3471), we examined the relationship between women's sexual orientation and attitudes toward menstruation cessation.

Gender Similarities and Differences in Casual Sex Acceptance Among Lesbian Women and Gay Men.

Popular wisdom and scientific evidence suggest women desire and engage in casual sex less frequently than men; however, theories of gender differences in sexuality are often formulated in light of heterosexual relations. Less is understood about sexual behavior among lesbian and gay people, or individuals in which there is arguably less motivation to pursue sex for reproductive purposes and fewer expectations for people to behave in gender-typical ways. Drawing from scripts theory and pleasure theory, in two studies (N =  465; N =  487) we examined lesbian and gay people's acceptance of casual sex.

Severe western Canadian wildfire affects water quality even at large basin scales.

Wildfires can have severe and lasting impacts on the water quality of aquatic ecosystems. However, our understanding of these impacts is founded primarily from studies of small watersheds with well-connected runoff regimes. Despite the predominance of large, low-relief rivers across the fire-prone Boreal forest, it is unclear to what extent and duration wildfire-related material (e.
