The proposed study will explore the relationship between trauma and delinquent behaviors and how this relationship differs between male and female adolescents. I aim to investigate why childhood exposure to interpersonal trauma is a stronger predictor of delinquency in females than males. Within female adolescents, I propose that the relationship between trauma and delinquency is mediated by disruption in attachment schema which is caused by exposure to trauma. Therefore, I will use multiple regression to analyze a moderated mediation model. This model is informed by Social Control Theory and a Feminist Pathways Perspective of crime and delinquency. Study participants will include male and female adolescents attending public high school in Austin, Texas. / text

This thesis is based on an empirical investigation of women's work in the airline industry. It aims to build on previous research into women's work by focusing not on the commodification of women's perceived nature (James, 1989), on femininity (Davies, 1979) or on women's sexuality (Hochschild, 1983, Adkins, 1995), but on the commodification of sexual difference, based on an analytical account of empirical research into the flight attendant as the iconic sexually differentialized labourer. The two key findings which emerged from the research are, first, that as one respondent put it, the flight attendant is " part mother, part servant, part tart"; her work is essentialized, feminized and also sexualized. The research suggested that these three processes are so closely interrelated that they actually constitute analytically distinct elements of the same labour process through which not only se~ gender and sexuality but sexual difference - "the specific properties ... qualities ... or attributes that women have developed or have been bound to historically ... which make them women not men" (De Lauretis, 1989: 5-6) - is commodified. The second theme is that, as sexually differentialized labourers, women workers are managed through the manipulation and maintenance of their 'organisational bodies', through a range of managerial techniques which involve, at least in part, a process of instrumental aestheticization. The underlying aim of this thesis is to offer a theoretical account of the sexual differentialization of women's work in an attempt to contribute to the development of a criticaL feminist theory of the commodification of sexual difference.

Reproductive competition among females is an under-studied aspect of behavioural ecology. In species where males provide non-sharable resources that enhance individual and offspring fitness, such as feeding young, intrasexual conflict among females should be expected. My thesis examined reproductive competition among female song sparrows by estimating the reproductive costs of losing male care and behavioural strategies females employed to avoid the loss of male care. I used a long-term study of song sparrows, a facultatively polygynous passerine, on Mandarte Island, British Columbia Canada, to examine the potential reproductive and survival costs that polygyny might have on females. I found that polygynous females without male care experienced lower nest and lifetime reproductive success than polygynous females with male care. In contrast, female status within polygynous groups had no impact on overwinter survival. Three strategies that females might use to avoid polygyny or ensure access to male parental care while in polygyny include 1) intrasexual aggression to deter secondary females from settling, 2) infanticide of primary female’s nest by secondary females to improve nesting status or 3) nest timing to either increase the comparative worth of the nest through synchrony, or eliminate competition for male care through asynchrony. Using a mount presentation experiment I found that resident females reacted as predicted if intrasexual aggressive behaviour was used to deter secondary female settlement and ensure male parental care. Over 18 years when polygyny occurred in the population, I found evidence that the presence of secondary females was correlated with a rise in the nest failure rate of primary females, but I found no evidence that polygynous females used nest timing strategies to influence access to male care. Overall, my results suggest that female song sparrows use aggressive behaviours to reduce secondary female settlement, and within polygynous groups secondary females may use infanticide to advance their status. Despite the existence of female strategies to circumvent the loss of fitness due to polygynous mating, polygyny still occurred regularly in the population. This observation suggests that the strategies described above are often not effective, or that their costs outweigh the potential gains to individual fitness.

The Arizona Child Acoustic Database consists of longitudinal audio recordings from a group of children over a critical period of growth and development (ages 2-7 years). The goal of this database is to 1) document acoustic changes in speech production that may be related to physical growth 2) inform development of a model of speech production for child talkers. This work was funded by NSF BSC-1145011 awarded to Kate Bunton, Ph.D. and Brad Story, Ph.D, Principal Investigators. This database contains longitudinal audio recordings of 55 American English speaking children between the ages of 2-7 at 3-month intervals. Since children began the study at different ages, some children have fewer recording sessions than others. The database can also be used to provide cross-sectional data for children of a specific age. Please refer to the subject data table for information on specific sessions available here http://arizona.openrepository.com/arizona/handle/10150/316065. All children were recorded using the same protocol; therefore, task numbers are consistent across children and sessions. A calibration tone is included as Record 1 for all sessions. The speech protocol focused on production of English monopthong and diphthong vowels in isolation, sVd, hVd, and monosyllabic real words. In addition, the protocol includes several nonsense vowel-to-vowel transitions. Speakers were prompted either verbally by investigators or by graphical prompts. Details of the protocol with reference to task numbers can be found in the protocol spreadsheet available here http://arizona.openrepository.com/arizona/handle/10150/316065. Details on data recording: All samples were recorded digitally using an AKG SE 300B microphone with a mouth to mic distance of approximately 10 inches. Signals were recorded digitally using a Marantz PMD671, 16 bit PCM (uncompressed) at 44.1KHz. Recordings are made available in .wav format. Individual zip files contain all recordings from a single session.
