The Nature of Single Female-led Family Homelessness and Mental Health Barth-Burkholder, Angelica Chronic homelessness, repeated episodes and/or lengthy durations of homelessness constitute the extreme negative end of the “housing continuum.” The “housing continuum” reflects levels of financial and social attainment or loss in terms of housing. Among the 'hidden' homeless, the number and proportion of single parent female-led families, which constitute the majority of the ‘new homeless’, have quickly grown among the chronically homeless, as opposed to the usually visible ‘old homeless’ – single adult males. Single-parent female-led homeless families follow cyclical patterns due to small or weak social networks and mental health problems related to abusive histories and domestic violence. Female children of homeless families frequently re-experience cyclical or chronic homelessness as a single adult females or family member. The US and UK have recognized crucial demographic variables and correlations between abusive histories, domestic violence, mental health problems and single-parent female-led cyclical and chronic family homelessness. Canada has not. At expense to mental health and social programs, Canada has focused on partially reversing neo-liberal cutbacks to income, employment and housing programs. These are absolutely necessary, but alone only mitigate the related issues of family homelessness. Just as the literature illustrates my research will demonstrate the same is true in Canada using questionnaires, semi-structured interviews and observation. I argue supporting strong and sustainable social networks, comprehensive, collaborated and coordinated mental health and social programs such as “Homes First” are required to overcome the ravishes of family homelessness.

Ultrastructure and physical properties of Escherichia coli expressing a plant pathogen protein responsible for inter-species infectivity Madarati, Cheghaf; Dahms, Tanya Phytopathogenic bacteria Pantoea stewartii subsp. stewartii (DC 283) has been demonstrated to aggregate in the gut and causes the death of the pea aphid (Acyrthosiphon pisum) by a flocculating behaviour that prevents honey dew secretion. This behaviour has been attributed to the (you cannot pass-1) ucp1 gene that potentially has an outer membrane function. Here we further explore the role of the ucp1 gene transformed into E. coli (pET21B) by atomic force microscopy and the effects of its expression on the ultrastructure and morphology of the E. coli (pET21B) cell surface. Induction of Ucp1 at various levels was correlated with aggregation of E. coli cells up to 95%. EPS material was produced in larger amounts around bacterial cells with higher induction levels of Ucp1. Interestingly, the surface subunits increased almost 10 nm in size when Ucp1 was induced, and stayed constant over different levels of induction. These results show that Ucp1 indeed has either a direct or indirect role on the ultrastructure of the E. coli cell wall surface, leading to aggregation behaviour.

Music Preference and Sensation Seeking: From Alternative to Sensational Hamel, Cory; Sharpe, Donald The field of music preference as it is related to sensation seeking has been studied by many researchers but the field still seems to lack in objective measures. The aim of the proposed study is to compare a self-report measure to an objective measure of music preference from participants and relate that preference to sensation seeking and personality, using the Sensation Seeking Scale Form V and the HEXACO personality inventory. It is anticipated that the music genres of rock and punk will be strongly associated with high scores on the Sensation Seeking Scale and the six personality dimensions of the HEXACO. The findings of this study will add to the research relating music preference both to personality and the sensation seeking construct.

Effects of Testosterone on Emotion Processing in Men Gould, Layla; Tottenham, Sykes Recent literature suggests that recognition of emotional facial expressions changes during hormone cycles. In women, emotional facial expression recognition accuracy has been found to change as hormone levels vary across the menstrual cycle; however it is not yet known whether men experience transient changes in emotion recognition related to daily hormonal cycles. This study examined whether there are transient changes in facial and prosodic emotion recognition across the day, at times when testosterone is highest and lowest. Participants consisted of males ranging in age from 18-30 years. All participants completed two testing sessions, one in the morning (high testosterone) and one in the afternoon (low testosterone). Participants completed two facial and prosodic emotion processing tasks during each session. In addition, self-report measures of emotional intelligence and empathy were administered to assess whether self-perceived emotional abilities also fluctuate. Scores from the two sessions were compared to determine if diurnal fluctuations in emotion processing abilities occurred.
