Floral structure, breeding system and fruit-set in the threatened sub-shrub Tetratheca juncea Smith (Tremandraceae)

Tetratheca juncea Smith (Tremandraceae) has undergone a range contraction of approx. 50 km in the last 100 years and is now listed as a vulnerable sub-shrub restricted to the central and north coast regions of New South Wales, Australia. There are approx. 250 populations in a 110 km north-south distribution and populations are usually small with fewer than 50 plants/clumps. The reproductive ecology of the species was studied to determine why seed-set is reportedly rare. Flowers are bisexual, odourless and nectarless. Flowers are presented dependentally and there are eight stamens recurved around the pistil. Anthers are poricidal, contain viable pollen and basally contain a deep-red tapetal fluid that is slightly oily. Thus flowers are presented for buzz pollinators, although none were observed at flowers during our study. The species was found to be facultatively xenogamous with only one in 50 glasshouse flowers setting seed autogamously, i.e. without pollinator assistance. Field studies revealed fertile fruit in 24 populations but production varied significantly across sites from exceedingly low (0.6 fruits per plant clump) to low (17 fruits per plant clump). Fruit-set ranged from 0 to 65%, suggesting that pollen vectors exist or that autogamy levels in the field are variable and higher than glasshouse results. Fruit production did not vary with population size, although in three of the five populations in the south-west region more than twice as much fruit was produced as in populations elsewhere. A moderately strong relationship between foliage volume and fruit : flower ratios suggests that bigger plants may be more attractive than smaller plants to pollinators. A review of Tetratheca pollination ecology revealed that several species are poorly fecund and pollinators are rare. The habitat requirements for Tetratheca, a genus of many rare and threatened species, is discussed. (C) 2003 Annals of Botany Company.

Chronic illness in non-heterosexual contexts: towards a critical LGBTQ health psychology

In this thesis, I contribute to the expansion of lesbian, gay, bisexual, trans and queer (LGBTQ) psychology by examining chronic illness within non-heterosexual contexts. Chronic illness, beyond the confines of HIV/AIDS, has been a neglected topic in LGBTQ psychology and sexual identity is often overlooked within health psychology. When the health of lesbian, gay and bisexual (LGB) people has been considered there has been an over-reliance on quantitative methods and comparative approaches which seek to compare LGB people?s health to their heterosexual counterparts. In contrast, I adopt a critical perspective and qualitative methods to explore LGBTQ health. My research brings together ideas from LGBTQ psychology and critical health psychology to explore non-heterosexuals? experiences of chronic illness and the discursive contexts within which LGB people live with chronic health conditions. I also highlight the heteronormativity which pervades academic health psychology as well as the „lay? health literature. The research presented in this thesis draws on three different sources of qualitative data: a qualitative online questionnaire (n=190), an online discussion within a newsgroup for people with diabetes, and semi-structured interviews with 20 LGB people with diabetes. These data are analysed using critical realist forms of thematic analysis and discourse analysis. In the first analytic chapter (Chapter 3), I report the perspectives of LGB people living with many different chronic illnesses and how they felt their sexuality shapes their experiences of illness. In Chapter 4, I examine heterosexism within an online discussion and consider the ways in which sexuality is constructed as (ir)relevant to a diabetes support forum. In Chapter 5, I analyse LGB people?s talk about the support family and partners provide in relation to their diabetes and how they negotiate wider discourses of gender, sexuality and individualism. In Chapter 6 I explore how diabetes intersects with gay and bisexual men?s sex lives. In the concluding chapter, I discuss the contributions of my research for a critical LGBTQ health psychology and identify some possible areas for future research.

Surveying sexualities: Internet research with non-heterosexuals

In this article we describe and evaluate the process of conducting online survey research about the legal recognition of same-sex relationships (key findings from which we have reported elsewhere, see Harding and Peel, 2006). Our aim in so doing is to contribute to the growing generic literature on internet-based research methods (Nosek et al., 2002; Rhodes et al., 2003; Stern, 2003; Strickland et al., 2003; Thomas et al., 2000) to the research methods literature within lesbian, gay, bisexual, trans and queer (LGBTQ) psychologies (Fish, 2000; Morris and Rothblum, 1999; Meezan and Martin, 2003; Mustanski, 2001) and also to extend the germinal literature focusing on internet research with non-heterosexual groups (Elford et al., 2004; Ellis et al., 2003; Ross et al., 2000). We begin by discussing the process of developing the online survey tool, before outlining the experience of the survey ‘going live’ and providing details of who completed the survey. We conclude by exploring some of the positives and pitfalls of this type of research methodology.

Chronic illness in non-heterosexual contexts: an online survey of experiences

In this article we contribute to the expansion of lesbian, gay, bisexual, transgender and queer (LGBTQ) health psychology beyond the confines of sexual health by examining the experiences of lesbian, gay and bisexual people living with non-HIV related chronic illness. Using a (predominantly) qualitative online survey, the perspectives of 190 LGB people with 52 different chronic illnesses from eight countries were collected. The five most commonly reported physical conditions were arthritis, hypertension, diabetes, asthma and chronic fatigue syndrome. Our analysis focuses on four themes within participants’ written comments: (1) ableism within LGBT communities; (2) isolation from LGBT communities and other LGB people living with chronic illness; (3)heteronormativity within sources of information and support and; (4) homophobia from healthcare professionals. We conclude by suggesting that LGBTQ psychology could usefully draw on critical health psychology principles and frameworks to explore non-heterosexual’s lived experiences of chronic illness, and also that there remains a need for specifically targeted support groups and services for LGB people with chronic illnesses.

'It's a double-edged thing':the paradox of civil partnership and why some couples are choosing not to have one

Since their introduction in 2005, thousands of same-sex couples in the UK have had a civil partnership. However, many other couples have chosen not to have one. This qualitative study explores why some same-sex couples are choosing not to have a civil partnership. Seven semi-structured interviews were conducted with 12 people (five couples and two individuals) who identified as lesbian, gay or bisexual, and analysed using discourse analysis. Participants' accounts were characterised by ambivalence about civil partnership, and three main paradoxes were identified: the 'good but not good enough' paradox, the 'unwanted prize' paradox and the 'legal rights v. social oppression paradox. A major source of ambivalence was support for rights but resistance to assimilation into dominant heteronormative cultural frameworks. Participants negotiated this ambivalence in a variety of ways, including considering how to have a civil partnership that is different from 'marriage', and adopting a pragmatic position. The analysis highlights the importance of social recognition and support for a range of relationship forms and identities, as well as for an ongoing critical debate about civil partnerships and same-sex marriage. © The Author(s) 2011.

Moving beyond heterosexism? The good, the bad and the indifferent in accounts of others’ reactions to important life events

Latterly the psychology of sexualities has diversified. There has been increased engagement with queer theory and a heightened focus on sexual practices alongside continued interrogation of heteronormativity via analyses of talk-in-interaction. In this article, I offer an argument for juxtaposing the incongruent in order to further interrogate manifestations of heterosexism in lesbian, gay, bisexual, trans and queer (LGBTQ) people’s lives. In this case, accounts of others’ reactions to a happy event and to a sad experience. By drawing on two contrasting data corpuses – 124 people planning or in a civil partnership and 60 women who had experienced pregnancy loss – there is increased potential for understanding variation in ‘normative’ and/or heteronormative interpretations of LGBTQ lives. I suggest that, despite significant legal and structural gains for LGBTQ communities in a number of Western countries in recent years, and lively internal debates within the psychology of sexualities field, critical examination of manifestations of heterosexism should remain a central focus.

Occupational therapists' attitudes toward homosexuality

Two hundred and eighty-five occupational therapists were surveyed to determine their general attitudes toward homosexuality, and whether certain demographic variables and means of exposure affected these attitudes. Attitudes ranged from neutral to positive. Those demographic variables that did affect respondents' attitudes were: sexual orientation, gender, and educational level. Those respondents who identified themselves as homosexual or bisexual had more positive attitudes than those who were heterosexual. Female respondents had more positive attitudes than male respondents and those respondents who held a Master's degree had more positive attitudes than those who held a Bachelor's degree. It was determined that respondents who had a family member or friend who was gay had more positive attitudes than those who did not. An unexpected finding was that respondents who had received adequate information about homosexuality in their occupational therapy curriculum had more negative attitudes than those who did not receive adequate information. It was therefore concluded that those occupational therapists who had not been provided with adequate information on homosexuality in their occupational therapy curriculum but had more positive attitudes toward homosexuality, were older and had more years of experience in occupational therapy. ^

The Experience of “Bottoming”: Considerations for Identity and Learning

Bottoms—Gay men who prefer to be penetrated, sexually—are more stigmatized than other gay men, and may develop and experience identities differently than other gay, bisexual, or heterosexual men. This paper explores intrinsic dispositions and extrinsic motivations that may lead bottoms to perform and embody psychosocial and sexual identities in intimate, interpersonal, and social contexts.

Trans Terrains: Gendered Embodiments and Religious Landscapes in Yogyakarta, Indonesia

Transgendered Indonesians live in the fourth most populated nation in the world with more Muslims than any other country. This thesis summarizes an ethnography conducted on one religiously oriented male-to-female transgender community known in the city of Yogyakarta as the waria. This study analyzes the waria’s gender and religious identities from an emic and etic perspective, focusing on how individuals comport themselves inside the world’s first transgender mosque-like institution called a pesantren waria. The waria take their name from the Indonesian words wanita (woman) and pria (man). I will chart how this male-to-female population create spaces of spiritual belonging and physical security within a territory that has experienced geo-religio-political insecurity: natural disasters, fundamentalist movements, and toppling dictatorships. This work illuminates how the waria see themselves as biologically male, not men. Anatomy is not what gives the waria their gender, their feminine expression and sexual attraction does. Although the waria self-identity as women/waria, in a religious context they perform as men, not women.

Los niveles de homofobia de los futuros docentes: una cuestión de derechos, salud mental y educación

La homofobia es una de las principales causas de discriminación dentro de los centros de enseñanza. El alumnado lésbico, gay, bisexual y transexual (en adelante LGBT) sufre un tipo de acoso específico que se traduce, entre otras cuestiones, en mayores porcentajes de suicidios y trastornos mentales. Esta situación, conocida por la comunidad científica, ha derivado en varios países –como Ecuador– en políticas educativas para la erradicación de la homofobia mediante legislaciones y planes de estudios que así lo establecen. Desde esta perspectiva, resultar lícito plantearse si estas nuevas políticas educativas están logrando formar a las nuevas generaciones de docentes para que puedan atender la diversidad afectivo sexual existente en las escuelas e institutos. Con la intención de dar respuesta a esta pregunta, se presentan los resultados de una investigación que valoró los niveles de homofobia del profesorado ecuatoriano. La muestra estuvo constituida por 465 futuros docentes (n= 465) que estaban realizando el último curso del grado de Magisterio. Para la evalua- ción se diseñó un cuestionario que posteriormente fue validado mediante una comisión de expertos y un estudio piloto. En el presente artículo se exponen los resultados obtenidos, así como las posibles discusiones que de ellos se pudieran extraen.

Spatial Articulations of Race, Desire, and Belonging in Western North Carolina

The sociocultural mythology of the South homogenizes it as a site of abjection. To counter the regionalist discourse, the dissertation intersects queer sexualities with gender and race and focuses on exploring identity and spatial formation among Black lesbian and queer women. The dissertation seeks to challenge the monolith of the South and place the region into multiple contexts and to map Black geographies through an intentional intersectional account of Black queer women. The dissertation utilizes qualitative research methods to ascertain understandings of lived experiences in the production of space. The dissertation argues that an idea of Progress has been indoctrinated as a synonym for the lgbtq civil rights movement and subsequently provides an analysis of progress discourses and queer sexualities and political campaigns of equality in the South. Analyses revealed different ways to situate progress utilizing the public contributions of three Black women interviewed for the dissertation. Moreover, the dissertation utilizes six Black queer and lesbian women to explain the multifarious nature of identities and their construction in place. Black queer and lesbian women produce spaces that deconstruct the normativity of stasis and physicality, and the dissertation explores the consequential realities of being a body in space. These consequences are particularly highlighted in the dissertation by discussions of the processes of racialization in the bounded and unbounded senses of space and place and the impacts of religious institutions, specifically Christianity. The dissertation concluded that no space is without complication. Other considerations should be made in the advancement of alleviating oppression deeply embedded in United States landscapes. Black women’s geographies offer epistemological and ontological renderings that enrich analyses of space, place, and landscape. The dissertation also concludes that Black women’s bodies represent sites for the production of geographic knowledge through narrating their spaces of material trajectories of interlocking, multiscalar lives.

Struggles for Citizenship in South Africa

South Africa’s first democratic constitution of 1996, which defines the content and scope of citizenship, emerged out of what the country’s Constitutional Court accurately described as ‘a deeply divided society characterized by strife, conflict, untold suffering and injustice which generated gross violations of human rights, the transgression of humanitarian principles in violent conflicts and a legacy of hatred, fear, guilt and revenge’ (cited in Jagwanth, 2003: 7). The constitution was internationally noteworthy for its expressed protection of women’s and sexual minority rights and its extension of rights of citizenship to socio-economic rights, such as rights of adequate healthcare, housing and education (SAGI, 1996). During South Africa’s first two decades of democracy, the Constitutional Court has proven its independence by advancing citizenship rights on a number of occasions (O’Regan, 2012). The struggle for citizenship was at the heart of the liberation struggle against the apartheid regime and within the complex dynamics of the anti-apartheid movement, increasingly sophisticated and intersectional demands for citizenship were made. South Africa’s constitutional rights for citizenship are not always matched in practice. The country’s high rates of sexual violence, ongoing poverty and inequality and public attitudes towards the rights of sexual minorities and immigrants lag well behind the spirit and letter of the constitution. Nevertheless, the achievement of formal citizenship rights in South Africa was the result of a prolonged and complex liberation struggle and analysis of South Africa demonstrates Werbner’s claim that ‘struggles over citizenship are thus struggles over the very meaning of politics and membership in a community’ (1999: 221). This chapter will begin with a contextual and historical overview before moving onto analyzing the development of non-racialism as a basis for citizenship, non-sexism and gendered citizenship, contestations of white, militarized citizenship and the achievement of sexual citizenship by the Lesbian, Gay, Bisexual and Transgender (LGBT) rights movement. As shall be made clear, all these citizenship demands emerged during the decades of the country’s liberation struggle.

Selection and Floral Evolution in Platanthera bifolia and P. chlorantha (Orchidaceae)

Natural selection mediated by pollinators has influenced the evolution of floral diversity of the flowering plants (angiosperms). The scope of this thesis was to study: 1) phenotypic selection, 2) mating systems, and 3) floral shifts involved in plant speciation. Model plant species were Platanthera bifolia and P. chlorantha (Orchidaceae). These orchids are moth-pollinated, strictly co-sexual (bisexual flowers), and produce a spike that displays 10-20 white flowers. I explored the influence of characters on plant fitness by using multiple linear regressions. Pollen removal (male fitness) and fruit set (female fitness) increased with more flowers per plant in three P. bifolia populations. There was selection towards longer spurs in a dry year when average spur length was shorter than in normal-wet years. Female function was sensitive to drought, which enabled an application of the male function hypothesis of floral evolution (Bateman's principle). The results show that selection may vary between populations, years, and sex-functions. I examined inbreeding by estimating levels of geitonogamy (self-pollination between flowers of an individual) with an emasculation method in two P. bifolia populations. Geitonogamy did not vary with inflorescence size. Levels of geitonogamy was 20-40% in the smaller, but non-significant in the larger population. This may relate to lower number of possible mates and pollinator activity in the smaller population. Platanthera bifolia exhibits the ancestral character state of tongue-attachment of pollinia on the pollinator. Its close relative P. chlorantha attaches its pollinia onto the pollinator's eyes. To explore the mechanism of a floral shift, pollination efficiency and speed was compared between the two species. The results showed no differences in pollination efficiency, but P. chlorantha had faster pollen export and import. Efficiency of pollination in terms of speed may cause floral shifts, and thus speciation.
