Orientador: José Sterza Justo / Banca: Fernando Silva Teixeira Filho / Banca: Diana Pancini de Sá Antunes Ribeiro / Banca: Rafael Siqueira de Guimarães / Banca: Paulo Roberto de Carvalho / Resumo: Os assexuais se definem como pessoas que não sentem atração sexual. A ideia de um sujeito assexual traz à tona discussões acerca dos usos políticos do sexo, coloca em exame as epistemologias da sexualidade e suscita debates a propósito dos modos de subjetivação contemporâneos.

(AS)Sexualidades: processo de subjetivação e resistência

No. of bitstreams: 1 Valéria Konc dos Santos.pdf: 727860 bytes, checksum: 8d8b61e24491b13f861608825f5e02cc (MD5) Previous issue date: 2016-10-03 / Conselho Nacional de Desenvolvimento Científico e Tecnológico / The term asexuality is understood in this work as a sexuality array characterized by the absence of sexual attraction or/and sexual activity. Asexuality has become of popular interest over the last years as the mainstream media has given some attention to the subject. Seen as a “novelty” in sexual multiplicities, it still needs further research. This dissertation embraces a theoretical investigation, approaching the locus of communities in virtual space and support forums. It addresses the problem of conceptualization and apprehension of asexuality in a context which many of its features are tangled in essentialist discourses (that define it as a fourth sexual orientation), political and identity discourses (especially when it becomes a movement fighting for recognition — observed in the major asexual communities), or in subject's singular processes. On the other hand, it also can be problematized through the queer approach directed at deconstructing and subverting heteronormative sexuality, as asexuality phenomena also strengthens the struggle and creation of that “new” that disturbs the status quo. People who think of themselves as asexual are beyond the limits of normative sexuality. They affirm that their condition is not a result of trauma, sexual repression, hormonal problems, religious choice, or explained by any other regulatory discourse. Thus, the discussion proposed here indicates that asexual people show rhizomatic and polymorphic sexuality. Although asexuality is encompassed in historical and social conditions that still nourish conservative and colonial thoughts, the conclusion of this work suggests that sexuality may be viewed as a line of flight and, therefore, it entails a micro-political force that struggles to prevent its own suppression as well as its weakening / humana caracterizada pela ausência de atração sexual e/ou ato sexual, vêm se popularizando nas grandes mídias, causando curiosidade e estranheza. Por ser considerada uma “novidade” dentro das multiplicidades sexuais, a assexualidade ainda carece de estudos mais profundos sobre o tema. Esta dissertação faz uma revisão bibliográfica, enfatizando o espaço virtual, lócus de comunidades e fóruns de apoio entre seus membros. A análise sobre o tema, discute sua difícil conceituação e entendimento, sobretudo porque vários aspectos se fundem a discursos essencialistas (quando é caracterizada como uma quarta orientação sexual), políticos e identitários (sobretudo quando se torna um movimento que luta por reconhecimento, tal como observado nas principais comunidades assexuais), até aos processos singulares do sujeito. Por outro lado, também pode ser problematizada através da abordagem queer, que atua na desestabilização e desconstrução da sexualidade heteronormativa, princípio que também se aplica a assexualidade enquanto um fenômeno que atua na resistência e na criação de um “novo” que perturbe o status quo. As pessoas que se autodenominam como assexuais, fogem do padrão da sexualidade normativa e enfatizam que sua condição como tal não está atrelada a traumas, repressão sexual, problema hormonal, escolha religiosa ou qualquer outro discurso regulatório. Desse modo, a discussão provocada sugere que os assexuais apresentam uma sexualidade rizomática e polimorfa. E a conclusão compreende que a assexualidade, apesar de estar elencado a fatores históricos e sociais de uma sociedade que ainda exibe resquícios de um pensamento conservador e colonial, também é uma linha de fuga e, nesse sentido, se modela como uma força micropolítica, que busca não permitir seu esmagamento e tampouco seu esvaecimento

Measuring social invisibility and erasure: Development of the Asexual Microaggressions Scale

Foster, Aasha January 2017 (has links)
The purpose of this dissertation was to create a psychometrically sound measure of asexual prejudice through microaggressions that can be used to document and identify the unique experiences of asexual people (i.e., those reporting a lack of sexual attraction towards others). Asexual prejudice encompasses anti-asexual beliefs and attitudes that stem from sexual normativity which promotes sexuality as the norm while positioning asexuality as deviant (Carrigan 2011; Chasin, 2011; Flore, 2014; Gupta, 2013). Applying Sue’s (2010) description of microaggressions, asexual microaggressions are conscious and/or unconscious daily occurrences of insults and invalidation that stem from implicit bias against asexual people and asexuality. Development of the scale included creating items with content that was derived from close readings of the literature on asexuality and related measures of discrimination, prejudice or bias as well as expert review for clarity and verifying applicability of content. A total of 738 participants participated on-line and half were randomly assigned to Phase 1 for the Exploratory Factor Analysis (EFA) while the other half was assigned to Phase 2 for the Confirmatory Factor Analysis (CFA). Results of the EFA indicate a 16 item four-factor structure for the AMS that capture expectations of sexuality, denial of legitimacy, harmful visibility, and assumptions of causality as descriptors of the types of microaggressions that occur. The CFA revealed support for the AMS total score with good internal consistency and strong validity as reflected in strong positive relationships with stigma consciousness, collective self-esteem, and another measure of discrimination and bias. Combined, the AMS is a valid and reliable measure of asexual prejudice. Contextualization of these results as well as implications for future research and clinical practice are discussed.

“Maybe all these random experiences form a cohesive picture”: towards a grounded theory of asexual college students’ identity development

Mollet, Amanda Lyn 01 May 2018 (has links)
For many individuals, the college environment provides the context in which one develops sexual identity. To understand students’ sexual identity development, many theories exist including theories on heterosexuality, queer sexual identities, and those broadly covering all sexual identities. One commonality across these theories is the assumption that all people experience sexual attraction. For students who identify with the spectrum of asexual identities, existing theories do not account for their experiences. Moreover, in hyper-sexualized college environments entrenched in hookup culture, asexual students experience harassment and erasure. The purpose of this study is to develop a theory of asexual college students’ identity development considering the context of their collegiate environment. Having a theory of asexual students’ identity development will allow students to see their experiences represented in theory, provide a framework for student affairs professionals to develop services and resources to support asexual students, and provide theoretical contributions for further research about asexuality. This study uses qualitative inquiry to learn from participants’ stories and experiences by employing constructivist grounded theory methods. Study participants include undergraduate and graduate students who self-identify within the spectrum of asexual identities. The study acknowledges students’ multiple identities including race, gender, ability status, and romantic attraction to create a theory where diverse individuals are depicted. Two questions guide this study: 1) What is the process of asexual college student identity development? and 2) How does the college context influence asexual college students’ identity development?

Genomic and phenotypic consequences of asexuality

Sharbrough, Joel 01 August 2016 (has links)
Sexual reproduction is expected to facilitate the removal of deleterious mutations from populations because biparental inheritance (i.e., segregation) and recombination during meiosis break down linkage disequilibria (LD), allowing mutations to be selected independently from their genetic background. Accordingly, the absence of recombination and segregation is expected to increase selective interference between loci, translating into reduced efficacy of natural selection. While there now exist multiple lines of evidence demonstrating that asexual lineages do experience accelerated accumulation of putatively harmful mutations, whether these mutations influence phenotype in a manner that could contribute to the maintenance of sex remains almost entirely unevaluated. Here, I use the New Zealand freshwater snail, Potamopyrgus antipodarum, to address these questions. In particular, I take advantage of the fact that the mitochondrial genome is expected to suffer from these mutational effects and interacts extensively with the nuclear genome to evaluate potential harmful effects of mutation accumulation in asexuals on a genome-wide scale. I present evidence that harmful mutations remain extant longer in asexual populations than in sexual populations, that the degree of functional constraint determines the extent of mutation accumulation in asexuals, that there is genetic variation for mitochondrial function in asexual lineages of P. antipodarum, and that phenotypic variation for mitochondrial function is mediated by both genetic and environmental variation. Together, these analyses provide strong evidence that asexual lineages are accumulating deleterious mutations, and that there is genetic variation, structured by lake, for mitochondrial function.

"Hela mitt liv har jag sagt att jag ligger runt" En studie om asexualitetens innebörd och dess relation till den obligatoriska sexualiteten

Göransson, Rebecka January 2017 (has links)
Asexualitet som begrepp är förhållandevis outforskat och omgärdas av många frågor, varför syftet med denna uppsats varit att belysa såväl asexualitetens innebörd som upplevelsen av att vara asexuell i ett samhälle där uttryckandet av sexualiteten ses som en avgörande del av individens hälsa och välmående. Inför denna uppsats har nio självidentifierade asexuella personer i åldrarna 18 till 45 år intervjuats och vägledande frågor i arbetet är; Hur beskriver informanterna asexualiteten och dess innebörd? Hur har informanternas individuella process till att anamma begreppet asexuell sett ut? Hur upplever informanterna att omgivningen bemöter/har bemött deras asexualitet, samt vilken uppfattning upplever de att omgivningen har kring asexualitet i stort? Påverkas informanterna av den obligatoriska sexualiteten som normsystem och hur återspeglas detta i så fall i deras berättelser?Studien visar att asexualitet är ett komplext begrepp som innefattar såväl individualism som mångfald. Asexuella personer möter en misstro och ett ifrågasättande från omgivningen utifrån ett antagande om en essentiell sexualitet, vilket återspeglar den obligatoriska sexualiteten som normsystem. Informanterna efterfrågar en förståelse för asexualitetens existens och en acceptans för att behovet av sexuella uttryck ser olika ut för alla människor. Vidare framkommer parallella beskrivningar av asexualiteten, som å ena sidan medfödd och inneboende del av individen och å andra sidan som någonting rörligt och i högsta grad föränderligt, vilket kan relateras till de normer som påverkar synen på asexualitet och andra icke-sexuella uttryck. Då dessa uttryck existerar, oavsett om de beskrivs som perioder av bristande lust eller livslång asexualitet, finns det ett värde i att bredda synen på såväl sexualiteten som asexualiteten. Detta då ett breddande kan skapa bättre förutsättningar för välmående i relation till såväl asexualiteten som sexualitetens föränderlighet under livets gång. / The concept of asexuality is relatively unexplored and surrounded by many questions, why the purpose of this essay has been to illustrate the meaning of asexuality as well as the experience of being asexual in a society where expressing your sexuality is considered to be a crucial part of the individual´s health and wellbeing. In this essay interviews have been conducted with nine self identified asexual individuals, aged 18 to 45 years and indicative questions in the essay are: How do the informants describe asexuality and its meaning? What has the individual process of embracing its meaning looked like? How do the informants experience society´s approach to asexuality and what percpetion of asexuality do they feel that society has over all? Are the informants affected by the compulsory sexuality as a normative system and if so, how is this reflected in their stories?This study shows that asexualty is a complex concept that includes both individualism and diversity. Asexual individuals face distrust and questioning attitudes in society, based on assumptions of an essential sexuality, which reflect compulsory sexuality as a normative system. The informants ask for an understanding of the excistence of asexuality, as well as acceptance of the fact that the need for sexual expressions is different for all people. Furthermore the study shows parallel descriptions of asexuality as congenital and inherent, as well as something highly variable, which can be related to the norms that affect the perception of asexuality and other non-sexual expressions. These expressions exist, regardless if they are described as temporary lack of sexual desire or life-long asexuality and therefore there is a value in broadening the perception of both sexuality and asexuality. This broadening can create better conditions for wellbeing in relation both to asexuality, and sexuality as changeable during the path of life.

Diversity and evolution of reproductive systems in Mycocepurus fungus-growing ants

Rabeling, Christian 12 October 2012 (has links)
The general prevalence of sexual reproduction over asexual reproduction among metazoans testifies to the evolutionary, long-term benefits of genetic recombination. Despite the benefits of genetic recombination under sexual reproduction, asexual organisms sporadically occur throughout the tree of life, and a few asexual lineages persisted over significant evolutionary time without apparent recombination. The study of asexual organisms therefore may provide clues to answer why almost all eukaryotes reproduce via meiosis and syngamy and why asexual eukaryotes are almost always evolutionarily short-lived. Towards understanding the evolution of asexual lineages in the Hymenoptera, I first review the diversity of reproductive systems in the Hymenoptera, introduce the study organism, the fungus-gardening ant Mycocepurus smithii, and discuss my research objectives. Second, I integrate information from reproductive physiology, reproductive morphology, natural history and behavior, to document that that queens of M. smithii are capable of thelytokous parthenogenesis, workers are sterile, and males are absent from the surveyed population. These results suggest that M. smithii might be obligately asexual. To place the origin and maintenance of asexual reproduction in M. smithii in an evolutionary context, I use molecular phylogenetic and population-genetic methods to (i) test if M. smithii reproduces asexually throughout its distribution range; (ii) infer if asexuality evolved once or multiple times; (iii) date the origin of asexual reproduction in M. smithii; and (iv) elucidate the cytogenetic mechanism of thelytokous parthenogenesis. During field collecting for these studies throughout the Neotropics, I discovered a new species of obligate social parasite in the genus Mycocepurus. Social parasites are of great interest to evolutionary biology in order to elucidate mechanisms demonstrating how parasites gained reproductive isolation from their host species in sympatry. I describe this new parasite species, characterize its morphological and behavioral adaptations to the parasitic lifestyle, and discuss the parasite’s life history evolution in the context of social parasitism in fungus-growing ants. The dissertation research integrates population-genetic, phylogenetic, physiological and morphological approaches to advance our understanding of the evolution of reproductive systems and diversity of life-history traits in animals. / text
