Investigation of the Relationship between Sexual Orientation and Objective Height, along with Predictors of Height Distortion

Studies that have used mostly self-reported height have found that men with a same-sex orientation and women with an other-sex orientation are shorter, on average, than men with an other-sex orientation and women with a same-sex orientation, respectively. This thesis examined whether an objective height difference exists or whether a psychosocial account (e.g., distortion of self-reports) may explain these putative height differences. Also, this thesis examined whether certain individual differences (e.g, gender roles and socially desirable responding) predict height distortion. Eight hundred and thirteen participants, recruited at Brock University, the Niagara Community and through surrounding LGBT events, completed self-reported height, measures of gender roles and socially desirable responding, and had their height measured. Using hierarchical linear regressions, it was found that Same-Sex/Both-Sex Oriented men were shorter, on average, than predominantly Other-Sex Oriented men; however, there was no difference in objective height between Same-Sex/Both-Sex Oriented women and predominantly Other-Sex Oriented women. These findings contribute to existing biological theories of men's sexual orientation development and do not contribute to biological theories of women's sexual orientation development. Height distortion was not related to sexual orientation and only marginally related to sex. Predictors of height distortion were Impression Management, in both men and women, and Unmitigated Agency, in men. These findings highlight the complexity of sexual orientation development in men and women. These findings also highlight the role of certain psychosocial factors in how people perceive their bodies and/or how they want their bodies to be perceived by others.

The Trouble with Inversion: an Examination of Science Sexual Orientation

Although some are excited about the possibility of using current scientific research into the biological causes of sexual orientation to ground rights claims, I argue that basing rights claims on this research is unwise because this research, specifically the hormonal, genetic, and structural research, is organized around the inversion assumption, a conceptual scheme within which some aspect of the biology of gay men and lesbians is thought to be inverted along sex lines.While there are many reasons to worry about the use of the inversion assumption, I focus on problems that arise from a further set of claims that must be assumed in order to make the use of the inversion assumption coherent. This further set of assumptions includes the claims (1) that heterosexuality is the standard state and that (2) this standard state is sexually-dimorphic and (3) deterministic. I argue that this set of assumptions is problematic because it results in ideological consequences that are both sexist and heterosexist.

Sexual orientation and sexual behavior patterns: Evaluation of agreement and variation in a cohort of male, African American drug users in Houston, TX

Background. Sexual orientation and sexual behavior among men have shown disagreement in past studies. The term "on the down low" has been adopted by many to describe "straight" identifying men who have sex with men but do not inform their primary female partner. Methods. This secondary analysis of data collected from the "DASH Project---A Hepatitis B Vaccine Model for HIV Vaccine Trial in Drug Users," assessed sexual behavior patterns among African American drug-using men over time. Using a screener questionnaire to determine sexual orientation and sexual behavior of the men, the study specifically evaluated "straight" identified men who have sex with women only (MSW) to determine what factors were associated with sexual behavior variation to include men during follow-up. The Fisher's Exact Test was used to evaluate the factors. Results. Variation of sexual behavior was highest among "bisexual" identified men followed by "gay" identified men. Fifteen of the original 593 "straight" and MSW men had sexual behavior variation to include men. In the analysis of "straight" and MSW men with variation in sexual behavior compared to those who did not, living on the streets, greater number of sexual partners, trading sex for drugs, and trading sex for money were associated with sexual behavior variation (all p-values <0.01). Conclusions. The factors were only associated when considering the interview when the variation occurred. The same factors at screening were not predictive of sexual behavior variation in the future. Environmental factors, such as living situation, appear to play a role in sexual behavior variations in "straight" and MSW men. ^ Keywords. sexual behavior, sexual orientation, Fisher's Exact Test^

Sexual orientation in Drosophila is altered by the satori mutation in the sex-determination gene fruitless that encodes a zinc finger protein with a BTB domain.

We have isolated a new Drosophila mutant, satori (sat), the males of which do not court or copulate with female flies. The sat mutation comaps with fruitless (fru) at 91B and does not rescue the bisexual phenotype of fru, indicating that sat is allelic to fru (fru(sat)). The fru(sat) adult males lack a male-specific muscle, the muscle of Lawrence, as do adult males with other fru alleles. Molecular cloning and analyses of the genomic and complementary DNAs indicated that transcription of the fru locus yields several different transcripts. The sequence of fru cDNA clones revealed a long open reading frame that potentially encodes a putative transcription regulator with a BTB domain and two zinc finger motifs. In the 5' noncoding region, three putative transformer binding sites were identified in the female transcript but not in male transcripts. The fru gene is expressed in a population of brain cells, including those in the antennal lobe, that have been suggested to be involved in determination of male sexual orientation. We suggest that fru functions downstream of tra in the sex-determination cascade in some neural cells and that inappropriate sexual development of these cells in the fru mutants results in altered sexual orientation of the fly.

Effects of disclosure of sexual identity at work for gay, lesbian, bisexual, transgender and intersex (GLBTI) employees in Queensland

All Australian businesses are governed by legislation aiming to prevent workplace discrimination based on sexual orientation and sexual identity and serious penalties apply to companies found contravening legislation. While other Australian studies have examined these issues, Queensland has either not been included or relevant data is not easily identified. This paper presents the results of an exploratory study using a quantitative survey to determine the consequences of disclosure of a person’s sexual orientation or gender identity to colleagues in workplaces in Queensland. Results suggest GLBTI workers are disclosing their sexuality more and are experiencing more discrimination in the workplace, despite anti-discrimination policies. This suggests the need to further investigate companies’ compliance with workplace legislation.

E-health: potential benefits and challenges in providing and accessing sexual health services

BACKGROUND: E-health has become a burgeoning field in which health professionals and health consumers create and seek information. E-health refers to internet-based health care and information delivery and seeks to improve health service locally, regionally and worldwide. E-sexual health presents new opportunities to provide online sexual health services irrespective of gender, age, sexual orientation and location. DISCUSSION: The paper used the dimensions of the RE-AIM model (reach, efficacy, adoption, implementation and maintenance) as a guiding principle to discuss potentials of E-health in providing and accessing sexual health services. There are important issues in relation to utilising and providing online sexual health services. For healthcare providers, e-health can act as an opportunity to enhance their clients' sexual health care by facilitating communication with full privacy and confidentiality, reducing administrative costs and improving efficiency and flexibility as well as market sexual health services and products. Sexual health is one of the common health topics which both younger and older people explore on the internet and they increasingly prefer sexual health education to be interactive, non-discriminate and anonymous. This commentary presents and discusses the benefits of e-sexual health and provides recommendations towards addressing some of the emerging challenges. FUTURE DIRECTIONS: The provision of sexual health services can be enhanced through E-health technology. Doing this can empower consumers to engage with information technology to enhance their sexual health knowledge and quality of life and address some of the stigma associated with diversity in sexualities and sexual health experiences. In addition, e-sexual health may better support and enhance the relationship between consumers and their health care providers across different locations. However, a systematic and focused approach to research and the application of findings in policy and practice is required to ensure that E-health benefits all population groups and the information is current and clinically valid and effective, including preventative approaches for various client groups with diverse needs.

In search of protection : sexual minority women in Canadian refugee determination

Le Canada accepte des demandes d’asile sur la base de l'orientation sexuelle depuis plus de 20 ans. Quoi qu’il en soit, cette recherche permet de douter du fait que les demandes sur la base de l’orientation sexuelle déposées par des femmes soient traitées de façon adéquate. Pour garantir l’accès à la protection des femmes appartenant à des minorités sexuelles, une analyse du risque de persécution fondé sur l'orientation sexuelle doit incorporer des considérations de genre ainsi que divers autres facteurs d’ordre social et culturel. À partir d’une étude de cas de demandes du statut de refugié déposées par des femmes sur la base de l’orientation sexuelle et rejetées par la Commission de l'immigration et du statut de réfugié entre 2010 et 2013, cette recherche identifie des procédés décisionnels problématiques qui font obstacle au droit d’asile de ces femmes. Les résultats de cette étude révèlent qu’une analyse intersectionnelle, laquelle prend acte des formes variées et multiples de l’oppression dans un contexte social donné, est d’importance cruciale pour une évaluation éclairée et non tronquée des risques de persécution pour les minorités sexuelles féminines. À la lumière de ces résultats, ce mémoire propose qu’une analyse intersectionnelle accompagne une nécessaire formation pour les membres de la Commission de l'immigration et du statut de réfugié du Canada sur des questions particulières à des minorités sexuelles.

A orientação homossexual e as investigações acerca da existência de componentes biológicos e genéticos determinantes; The homosexual orientation and investigations about the existence of components biological and genetics determinants

The male and female homosexual orientation has substantial prevalence in humans and can be explained by determinants of various levels: biological, genetic, psychological, social and cultural. However, the biological and genetic evidence have been the main hypotheses tested in scientific research in the world. This article aims to review research studies about the existence of genetic and biological evidence that determine homosexual orientation. Was conducted a review of the literature, using the database MedLine/PubMed and Google scholar. The papers and books were searched in Portuguese and English, using the following keywords: sexual orientation, sexual behavior, homosexuality, developmental Biology and genetics. Was selected papers of the last 22 years. Were found five main theories about the biological components: (1) fraternal birth order, (2) brain androgenization and 2D:4D ratio; (3) brain activation by pheromones; and (4) epigenetic inheritance; and four theories about the genetic components: (1) genetic polymorphism; (2) pattern of X-linked inheritance; (3) monozygotic twins; and (4) sexual antagonistic selection. Concluded that there were many scientific evidence found over time to explain some of biological and genetic components of homosexuality, especially in males. However, today, there is no definitive explanation about what are the determinants of homosexual orientation components.

Orientação sexual como tema transversal em escolas públicas de Curralinhos-PI

Este estudo objetivou analisar a prática docente relacionada à orientação sexual enquanto tema transversal em escolas públicas no munícipio de Curralinhos-PI, e neste encalço, identificar as formas de práticas docentes relacionadas à orientação sexual enquanto tema transversal; caracterizar os fatores condicionantes para a realização da abordagem da orientação sexual em sala de aula; verificar a contribuição das oficinas do Programa Saúde e Prevenção na Escola (SPE) na formação continuada da prática docente e, a percepção de professores e alunos, quanto à relevância da abordagem do tema em questão de forma sistemática e transversal nas referidas escolas. Trata-se de um estudo com abordagem qualitativa e quantitativa com função de complementaridade, realizada em duas escolas públicas (X e Y) do município de Curralinhos-PI, de ensino fundamental e ensino médio, respectivamente, envolvendo uma amostra de 8 (oito) professores, que participaram das oficinas do SPE e 116 alunos, sendo 54 da escola X e 62 da escola Y. Os instrumentos da coleta de dados foram a entrevista e o questionário semiestruturados, originários de um roteiro de questões-guia. A coleta de dados foi realizada no segundo semestre de 2011, nos meses de agosto a setembro. Os resultados apontaram que é grande a necessidade de se discutir e implementar a orientação sexual no espaço escolar, pois embora a maioria dos professores entrevistados reconheçam a importância de se trabalhar a orientação sexual como tema transversal e demonstrarem conhecer esta proposta dos Parâmetros Curriculares Nacionais (PCNs), ainda são difusas as práticas incorporadas em suas atividades pedagógicas. Quanto aos alunos, evidenciaram que ainda se fazem presentes dúvidas e angústias, assim como dificuldades para a lida com o tema da sexualidade.
