Evolutionary theories of ageing and senescence provide a framework that allows to understand why apparently maladaptive senescent phenotypes are observed under natural conditions, despite the fact that natural selection should, at first sight, be opposed to mechanisms that lead to the deterioration of bodily functions with advancing age. While ageing has been shown in the wild and has been explored under artificial laboratory conditions, sex-dependent pattern were not considered in detail. The aim of this thesis is to draw from the existing theories of sexual selection, life-history and sexual conflict, to get a more complete understanding of sex-specific effects on ageing patterns. The organism I use in all experiments is the Black Field Cricket Teleogryllus commodus. To test for sex-specific demographic ageing patterns in the wild, I use a capture-mark-recapture study and analyse the resulting data with a new method that combines classic capture-recapture models with a recent mathematical technique that allows to estimate survival probabilities from recapture data for which the date of births of animals are unknown (Chapter 2). I test for reproductive and demographic ageing under near-natural conditions in field enclosure (Chapter 3). In laboratory based manipulation studies I estimate the effect of a) different juvenile and adult diets on the ageing patterns (Chapter 4), and b) a reduction of the ability to spend energy on calling and how this relates to lifespan (Chapter 5). In a half-sib breeding design I measure early and late reproductive effort in males and in females to estimate genetic correlations and thereby test for antagonistic pleiotropy between early and late components and between males and females. The studies in the wild indicate that Teleogryllus commodus senesce under natural conditions and that males have overall higher mortality rates. Females, not males, show reproductive ageing under both enclosure and laboratory conditions. The genetic architecture revealed no discord between male and female fitness components and there was no evidence for antagonistic pleiotropy between early and late fitness components. These results show that a) it is important to include male measures of reproductive effort in ageing studies and that b) the field of ageing research should benefit a lot from incorporating sexual selection, life-history and sexual conflict theory.

This thesis explores the links between handbag dance music and gay male culture. Handbag (colloquial British slang for ‘uplifting,’ ‘girly’ remixes of Top 40 songs and similar club material) is frequently derided within club culture for being predictable, formulaic, and ‘commercial.’ However, the same music is hugely popular within gay male clubs. Significantly, handbag tends to retain clear song structures, as opposed to the more open-ended instrumental ‘tracks’ which are the norm in electronic dance music. Why would a marginalised group adopt such a low-status music as its own? Why does handbag have such low status in the first place? This thesis argues that the field of ‘electronic dance music’ is rife with distinctions between ‘credible’ dance music and ‘commercial trash,’ and that these distinctions are frequently used to downplay song-based genres. The pleasures of handbag can be better understood if we pay attention to the ways that ‘songs’ (rather than instrumental ‘tracks’) have always played an important role in club music. Love in the First Degree questions an emerging orthodoxy in sociology and popular music studies: that issues of identity can only be approached ethnographically. By interrogating the music itself, the thesis explores the ways in which musical conventions can be deployed to arouse desire on the dance floor—and the reasons that these musical strategies are particularly useful in gay male clubs. / Doctor of Philosophy (PhD)

<p>Studiens syfte är att undersöka målsättning och undervisningsmetoder ur ett mångkulturellt perspektiv hos biologilärare och RFSU:s Vägvisare. RFSU:s Vägvisare är ett metodmaterial för lärare som undervisar i sex- och samlevnad. Begreppet mångkultur avgränsas i studien till etnicitet, genus/kön och sexualitet. För att samla in empiriskt material gjordes fem stycken kvalitativa intervjuer med biologilärare på skolor för grundskolans senare år i Västra Sverige. Utifrån en textanalytisk metod analyserades det empiriska materialet. Resultatet av vår studie visade på att lärarna endast tog hänsyn till mångkultur i vissa fall. I jämförelsen mellan lärarna och RFSU:s Vägvisare framkom det, att de till viss del hade samma målsättningar och arbetmetoder, men överlag tar RFSU:s Vägvisare större hänsyn till mångfalden i klassrummet.</p>

<p>Ett ord som på pappret inte tar så stor plats, men som i verkligheten är både laddat och exponerat. Sex kittlar och fascinerar. Men det finns också en annan värld, bortom penetration och petting. Denna artikelserie skildrar två olika delar av en verklighet utan det där som alla pratar om.</p>
