Neighborhood-Level LGBT Hate Crimes and Current Illicit Drug Use among Sexual Minority Youth
Dustin Duncan, Mark Hatzenbuehler & Renee Johnson
Drug and Alcohol Dependence, forthcoming
Objective: To investigate whether past-30 day illicit drug use among sexual minority youth was more common in neighborhoods with a greater prevalence of hate crimes targeting lesbian, gay, bisexual, and transgender (LGBT, or sexual minority) individuals.
Methods: We used a population-based survey of public school youth in Boston, Massachusetts, consisting of 1,292 9th-12th grade students from the 2008 Boston Youth Survey Geospatial Dataset (sexual minority n = 108). Data on LGBT hate crimes involving assaults or assaults and battery between 2005 and 2008 were obtained from the Boston Police Department and linked to youths’ residential address. Youth reported past-30 day use of marijuana and other illicit drugs. Wilcoxon-Mann-Whitney tests and corresponding p-values were computed to assess differences in substance use by neighborhood-level LGBT assault hate crime rate among sexual minority youth (n = 103).
Results: The LGBT assault hate crime rate in the neighborhoods of sexual minority youth who reported current marijuana use was 23.7 per 100,000, compared to 12.9 per 100,000 for sexual minority youth who reported no marijuana use (p = 0.04). No associations between LGBT assault hate crimes and marijuana use among heterosexual youth (p > 0.05) or between sexual minority marijuana use and overall neighborhood-level violent and property crimes (p > 0.05) were detected, providing evidence for result specificity.
Conclusions: We found a significantly greater prevalence of marijuana use among sexual minority youth in neighborhoods with a higher prevalence of LGBT assault hate crimes. These results suggest that neighborhood context (i.e., LGBT hate crimes) may contribute to sexual orientation disparities in marijuana use.

Is Rising Obesity Causing a Secular (Age-Independent) Decline in Testosterone among American Men?
Allan Mazur, Ronny Westerman & Ulrich Mueller
PLoS ONE, October 2013
Abstract:
The testosterone of men in industrial societies peaks in their twenties and tends to decline with increasing age. Apart from this individual-level decline, there have been reports of a secular (age-independent population-level) decline in testosterone among American and Scandinavian men during the past few decades, possibly an indication of declining male reproductive health. It has been suggested that both declines in testosterone (individual-level and population-level) are due to increasing male obesity because men in industrial society tend to add body fat as they age, and overall rates of obesity are increasing. Using an unusually large and lengthy longitudinal dataset (991 US Air Force veterans examined in six cycles over 20 years), we investigate the relationship of obesity to individual and population-level declines in testosterone. Over twenty years of study, longitudinal decline in mean testosterone was at least twice what would be expected from cross-sectional estimates of the aging decline. Men who put on weight intensified their testosterone decline, some greatly so, but even among those who held their weight constant or lost weight during the study, mean testosterone declined 117 ng/dl (19%) over 20 years. We have not identified the reason for secular decline in testosterone, but we exclude increasing obesity as a sufficient or primary explanation, and we deny the supposition that men who avoid excessive weight will maintain their youthful levels of testosterone.

When Do Legislators Defy Popular Sovereignty? Testing Theories of Minority Representation Using DOMA
Benjamin Bishin & Charles Anthony Smith
Political Research Quarterly, December 2013, Pages 794-803
Abstract:
What explains the behavior of legislators on bills that restrict the rights of marginalized minorities? Studies of representation typically focus on factors like party or public opinion but seldom account for theories of minority representation like electoral capture or subconstituency politics. One reason for this is that data allowing for the comparison of these theories are seldom available for U.S. House districts. We overcome this hurdle by implementing multilevel regression with post-stratification to estimate opinion on gay marriage during the 1996 Defense of Marriage Act vote. We show that subconstituency politics explains legislators’ behavior better than electoral capture, party, or public opinion.

Masculine Men Articulate Less Clearly
Vera Kempe, David Puts & Rodrigo Cárdenas
Human Nature, December 2013, Pages 461-475
Abstract:
In previous research, acoustic characteristics of the male voice have been shown to signal various aspects of mate quality and threat potential. But the human voice is also a medium of linguistic communication. The present study explores whether physical and vocal indicators of male mate quality and threat potential are linked to effective communicative behaviors such as vowel differentiation and use of more salient phonetic variants of consonants. We show that physical and vocal indicators of male threat potential, height and formant position, are negatively linked to vowel space size, and that height and levels of circulating testosterone are negatively linked to the use of the aspirated variant of the alveolar stop consonant /t/. Thus, taller, more masculine men display less clarity in their speech and prefer phonetic variants that may be associated with masculine attributes such as toughness. These findings suggest that vocal signals of men’s mate quality and/or dominance are not confined to the realm of voice acoustics but extend to other aspects of communicative behavior, even if this means a trade-off with speech patterns that are considered communicatively advantageous, such as clarity and indexical cues to higher social class.

Shape Differences Between the Faces of Homosexual and Heterosexual Men
Jaroslava Varella Valentova et al.
Archives of Sexual Behavior, forthcoming
Abstract:
Previous studies have shown that homosexual men differ from heterosexual men in several somatic traits and lay people accurately attribute sexual orientation based on facial images. Thus, we may predict that morphological differences between faces of homosexual and heterosexual individuals can cue to sexual orientation. The main aim of this study was to test for possible differences in facial shape between heterosexual and homosexual men. Further, we tested whether self-reported sexual orientation correlated with sexual orientation and masculinity–femininity attributed from facial images by independent raters. In Study 1, we used geometric morphometrics to test for differences in facial shape between homosexual and heterosexual men. The analysis revealed significant shape differences in faces of heterosexual and homosexual men. Homosexual men showed relatively wider and shorter faces, smaller and shorter noses, and rather massive and more rounded jaws, resulting in a mosaic of both feminine and masculine features. In Study 2, we tested the accuracy of sexual orientation judgment from standardized facial photos which were assessed by 80 independent raters. Binary logistic regression showed no effect of attributed sexual orientation on self-reported sexual orientation. However, homosexual men were rated as more masculine than heterosexual men, which may explain the misjudgment of sexual orientation. Thus, our results showed that differences in facial morphology of homosexual and heterosexual men do not simply mirror variation in femininity, and the stereotypic association of feminine looking men as homosexual may confound judgments of sexual orientation.

Sexual Orientation, Prejudice, and Segregation
Erik Plug, Dinand Webbink & Nick Martin
Journal of Labor Economics, January 2014, Pages 123-159
Abstract:
This article examines whether gay and lesbian workers sort into tolerant occupations. With information on sexual orientation, prejudice, and occupational choice taken from Australian Twin Registers, we find that gays and lesbians shy away from prejudiced occupations. We show that our segregation results are largely driven by those gay and lesbian workers with disclosed identities and are robust to the inclusion of unobserved factors that are inherited and observed factors that strongly correlate with productive skills and vocational preferences. Our segregation estimates are consistent with prejudice-based theories of employer and employee discrimination against gay and lesbian workers.

Journal of Experimental Social Psychology, forthcoming
Abstract:
We hypothesized that perceivers high in sexual prejudice would fail to unitize romantically involved men into a single mental representation, instead perceiving the men as separate individuals. Two studies provided support for our hypothesis. In Study 1, sexual prejudice predicted perceptions of compatibility, intimacy, emotional satisfaction, and temporal stability for couples described as same-sex male but not for couples described as opposite sex. In Study 2, participants completed a modified who-said-what task in which men of two different same-sex couples presented facts about their relationships. Those low, versus high, in sexual prejudice committed significantly more within-couple relative to between-couple errors in their ascriptions, indicating that prejudice negatively predicted categorization along the dimension of couple. These results have important implications for how those high in sexual prejudice form impressions of same-sex couples and, ultimately, for how prejudiced attitudes affect mental representations of romantic couples.

Low 2D:4D Values Are Associated with Video Game Addiction
Johannes Kornhuber et al.
PLoS ONE, November 2013
Abstract:
Androgen-dependent signaling regulates the growth of the fingers on the human hand during embryogenesis. A higher androgen load results in lower 2D:4D (second digit to fourth digit) ratio values. Prenatal androgen exposure also impacts brain development. 2D:4D values are usually lower in males and are viewed as a proxy of male brain organization. Here, we quantified video gaming behavior in young males. We found lower mean 2D:4D values in subjects who were classified according to the CSAS-II as having at-risk/addicted behavior (n = 27) compared with individuals with unproblematic video gaming behavior (n = 27). Thus, prenatal androgen exposure and a hyper-male brain organization, as represented by low 2D:4D values, are associated with problematic video gaming behavior. These results may be used to improve the diagnosis, prediction, and prevention of video game addiction.

Abstract:
In this paper, we find that a proxy of prenatal testosterone exposure (i.e., digit ratio) is a significant predictor of preferences for products that differ in perceived masculinity vs. femininity. A more masculine (feminine) digit ratio predicts choice of products that have an increasingly masculine (feminine) image. This relationship is statistically significant for male consumers, but not for females.

Weight Status and Sexual Orientation: Differences by Age and Within Racial and Ethnic Subgroups
Nicholas Deputy & Ulrike Boehmer
American Journal of Public Health, January 2014, Pages 103-109
Objectives: We determined differences in weight at age 18 years and at current age and weight change by sexual orientation within different racial/ethnic populations, stratifying by gender.
Methods: We used 2001–2007 data from the California Health Interview Survey, resulting in an unweighted sample of 120 274 individuals aged 18 to 74 years. Using regression models, we examined overweight status and change in weight by sexual orientation, stratifying by race/ethnicity and gender.
Results: Compared with heterosexual women of the same race/ethnicity, White and African American lesbians and bisexuals had increased likelihood of being overweight at age 18 years and maintaining overweight status during adulthood. Sexual minority status was unrelated to weight among Latinas and inconsistently linked to weight among Asian women compared with heterosexual women of the same race/ethnicity. Sexual minority status was protective against unhealthy weight among White, African American, Asian, and Latino men compared with heterosexual counterparts of the same race/ethnicity. This protective effect was seen after age 18 years except among African American bisexual men.
Conclusions: Our findings indicate a need for age- and culture-sensitive interventions that reduce weight or prevent weight gain in sexual minority women and men.

Abstract:
Human asexuality is defined as a lack of sexual attraction to anyone or anything and it has been suggested that it may be best conceptualized as a sexual orientation. Non-right-handedness, fraternal birth order, and finger length ratio (2D:4D) are early neurodevelopmental markers associated with sexual orientation. We conducted an Internet study investigating the relationship between self-identification as asexual, handedness, number of older siblings, and self-measured finger-lengths in comparison to individuals of other sexual orientation groups. A total of 325 asexuals (60 men and 265 women; M age, 24.8 years), 690 heterosexuals (190 men and 500 women; M age, 23.5 years), and 268 non-heterosexuals (homosexual and bisexual; 64 men and 204 women; M age, 29.0 years) completed online questionnaires. Asexual men and women were 2.4 and 2.5 times, respectively, more likely to be non-right-handed than their heterosexual counterparts and there were significant differences between sexual orientation groups in number of older brothers and older sisters, and this depended on handedness. Asexual and non-heterosexual men were more likely to be later-born than heterosexual men, and asexual women were more likely to be earlier-born than non-heterosexual women. We found no significant differences between sexual orientation groups on measurements of 2D:4D ratio. This is one of the first studies to test and provide preliminary empirical support for an underlying neurodevelopmental basis to account for the lack of sexual attraction characteristic of asexuality.

Abstract:
This study examined whether expressive writing could help lesbian, gay, bisexual, or queer (LGBQ) hate speech victims increase forgiveness for offenders, and accelerate cortisol recovery following a discussion task in which they recalled the details of their experiences. Participants (N = 46) were assigned to a benefit-finding, traumatic disclosure writing, or control condition. The findings indicate that benefit-finding promoted forgiveness and reduced cortisol values, whereas traumatic disclosure writing only accelerated cortisol recovery. Analyses of the linguistic features of victims' narratives revealed that the amount of emotion-related words related to cortisol recovery, whereas the greater use of cognitive words was related with forgiveness. Implications for theory, methodological comparison, and future research are discussed.

Queer Women in the Hookup Scene: Beyond the Closet?
Leila Rupp et al.
Gender & Society, forthcoming
Abstract:
The college hookup scene is a profoundly gendered and heteronormative sexual field. Yet the party and bar scene that gives rise to hookups also fosters the practice of women kissing other women in public, generally to the enjoyment of male onlookers, and sometimes facilitates threesomes involving same-sex sexual behavior between women. In this article, we argue that the hookup scene serves as an opportunity structure to explore same-sex attractions and, at least for some women, to later verify bisexual, lesbian, or queer sexual identities. Based on quantitative and qualitative data and combining queer theory and identity theory, we offer a new interpretation of women’s same-sex practices in the hookup culture. Our analysis contributes to gender theory by demonstrating the utility of identity theory for understanding how non-normative gender and sexual identities are negotiated within heteronormatively structured fields.

Olfactory Performance Is Predicted by Individual Sex-Atypicality, but Not Sexual Orientation
Lenka Nováková, Jaroslava Varella Valentová & Jan Havlíček
PLoS ONE, November 2013
Abstract:
Many previous studies have reported robust sex differences in olfactory perception. However, both men and women can be expected to vary in the degree to which they exhibit olfactory performance considered typical of their own or the opposite sex. Sex-atypicality is often described in terms of childhood gender nonconformity, which, however, is not a perfect correlate of non-heterosexual orientation. Here we explored intrasexual variability in psychophysical olfactory performance in a sample of 156 individuals (83 non-heterosexual) and found the lowest odor identification scores in heterosexual men. However, when childhood gender nonconformity was entered in the model along with sexual orientation, better odor identification scores were exhibited by gender-nonconforming men, and greater olfactory sensitivity by gender-conforming women, irrespective of their sexual orientation. Thus, sex-atypicality, but not sexual orientation predicts olfactory performance, and we propose that this might not be limited to olfaction, but represent a more general phenomenon.

Abstract:
160 undergraduate women (M age = 20.3, SD = 1.52) were assessed for depression, drug abuse, and eating disorders. The age of menarche was positively correlated with higher scores on a screening measure for eating disorders, a finding opposite to past studies for adolescent girls.
