Queer Encounters: exploring experiences of (gender)queers in women's public washroom spaces

This thesis is based on 13 qualitative interviews conducted with 12 individuals whom I refer to as (gender)queers in Winnipeg, Manitoba, and St. Catharines, Ontario. Drawing on queer theory and the literature of sexuality and space, I explore how (gender)queers experience women's public washrooms as gendered and heterosexualized spaces. I examine the degree to which a simultaneous heterosexing and female gendering of women's public washrooms is linked to the marginalization and sometimes violent exclusion of (gender)queers within these particular spaces. I also discuss the ways in which (gender)queers may use a variety of strategies aimed at navigating heterosexualized and gendered public washrooms. Finally, I explore alternatives to conventional washrooms spaces, including the gender-neutral washrooms, multi-stall non-gendered public washrooms, and public washrooms in queer spaces.

The effect of social condition and diet on the frequency of male-male agonistic displays in the field cricket, gryllus bimaculatus /

The frequency and type of agonistic displays involved in male-male encounters should be significantly influenced by the presence of females. Discrete agonistic displays vary in energy expenditure and risk, and therefore should be dependent on available resources. The influence of live females and the scent of females, on the frequency of male agonistic displays was observed in a laboratory terrarium using the field cricket Gryllus bimaculatus. The effect of energy constraints on display frequency was also determined. Half the males were fed a diet high in protein and fet; the other males were fed a lower quality diet, for a 7-11 day period. The frequency of five individual displays and mating frequency were recorded using an Event Recorder and notebook. Each group of males was presented with three experimental conditions, over three days, involving the presence or absence of live females and female scent. The presence of females elicited an increase in all displays except antennation; female scent increased the frequency of antennations, mandible flares and grapples, but to a lesser extent than did live females. The frequency of grapples significantly increased for males fed the high quality diet; however diet did not influence the other displays. The combined influence of diet and condition was significant for mandible flare only. Mating frequency was not influenced by diet. However, the frequency ofthe displays were positively correlated with mating frequency for high quality fed males. Escalated displays involving high costs, such as grapple and mandible flare, increased in frequency when the benefits of winning contests were high in G.bimaculatus. Escalation to grapple behaviour was less evident for males fed the lower quality diet as this imposed energy constraints on high cost displays.

The surficial geology, sedimentology and geochemistry of the late glacial sediments and Paleozoic bedrock in the Campbellford area, Ontario, with special reference to the Dummer Complex /

The Dummer Complex extends 180 km along the Precambrian - Paleozoic contact from Tamworth to Lake Simcoe. It is composed of coarse, angular Paleozoic clasts in discontinuous, pitted, hummocky deposits. Deposits are usually separated by bare or boulder strewn bedrock, but have been found in the southern drumlinized till sheet. Dummer Complex deposits show rough alignment with ice-flow. Eskers cross-cut many of the deposits. Dummer sediment subfacies are defined on the basis of dominant coarse grain size and lithology, which relate directly to the underlying Paleozoic formation. Three subglacial tills are identified based on the degree of comminution and distance of transport; the immature facies of the Dummer Complex; the mature facies of the drumlinized till sheet and; the submature facies which is transitional. Carbonate geochemistry was used for till-bedrock correlation in various grain sizes. Of the 3 Paleozoic formations underlying the Dummer Complex, the Gull River Fm. is geochemically distinctive from the Bobcaygeon and Verulam Formations using Ca, Mg, Sr, Cu, Mn, Fe and Na. The Bobcaygeon Fm. and Verulam Fm. can be differentiated using Ca and the Sr/Ca ratio. The immature facies from 1.0 phi and finer is dominated by the non-carbonate, long distance transported component which decreases slightly downice. The submature till facies contains more long distance material than the immature facies. Sr and Mn can be used to correlate the Gull River immature till facies to the underlying bedrock the other subfacies could not be distinguished from each other or their respective source formation. This method proved to be ineffective for sediments with greater than 35% non-carbonate component, due to leaching of elements by the dissolving acid.The Dummer Complex is produced subglacially , as the compressional ice encounters the permeable Paleozoic carbonates. The increased shear strength of the ice and pore pressures in the carbonates results in the basal ice zones becoming debris ladden. Cleaner ice overrides the basal debris . laden dead ice which then acts as the glacier bed. During retreat, the Simcoe lobe stagnates as flow is cut-off by the Algonquin Highlands.

Athletic injury care training in high school coaches

The purpose of this qualitative study was to understand the client and occupational therapist experiences of a mental health group. A secondary aim was to explore the extent to which this group seemed to have reflected a client-centred approach. The topic emerged from personal and professional issues related to the therapist as teacher and to inconsistencies in practice with the profession's client-centred philosophy. This philosophy, the study's frame of reference, was established in terms of themes related to the client-therapist relationship and to client values. Typical practice was illustrated through an extensive literature review. Structured didacticexperiential methods aiming toward skill development were predominant. The interpretive sciences and, to a lesser extent, the critical sciences directed the methodology. An ongoing support group at a community mental health clinic was selected as the focus of the study; the occupational therapist leader and three members became the key participants. A series of conversational interviews, the . core method of data collection, was supplemented by observation, document review, further interviews, and fieldnotes. Transcriptions of conversations were returned to participants for verification and for further reflection Analysis primarily consisted of coding and organizing data according to emerging themes. The participants' experiences of group, presented as narrative stories within a group session vignette, were also returned to participants. There was a common understanding of the group's structure and the importance of having "air time" within the group; however, differences in perceptions of such things as the importance of the group in members' lives were noted. All members valued the therapeutic aspects of group, the role of group as weekly activity and, to a lesser extent, the learning that came from group. The researcher's perspective provided a critique of the group experience from a client-centred perspective. Some areas of consistency with client-centred practice were noted (e.g., therapist attitudes); however the group seemed to function far from a client-centred ideal. Members held little authority in a -relationship dominated by the leaders, and leader agendas rather than member values controlled the session. Possible reasons for this discrepancy ranging from past health care encounters through to co-leader discord emerged. The actual and potential significance of this study was discussed according to many areas of implications: to OT practice, especially client-centred group practice, to theory development, to further areas of research and methodology considerations, to people involved in the group and to my personal growth and development.

Body size in the field cricket Gryllus integer (Orthoptera : Gryllidae) :heritability and male mating success

The influence of male body weight on the aggressive and mating behaviour of male Gryllus integer was studied under laboratory conditions. The relationship between adult age and weight was first determined; female weight increased and male weight decreased with age. Virgin males that had been isolated since the adult molt were paired for similar age and a difference in weight of greater than 200 mg. Paired males and a virgin female were observed in a glass arena for 24 minutes or until a mating occurred. Larger males mated significantly more often than smaller males. Larger males attacked more often, were more successful in aggressive encounters and had more contact with the female. Males that did not mate had lower rates of courtship and mounts than males that mated. Females in trials that did not result in a mating were signifcantly heavier than females in trials that resulted in a mating. Larger males that mated were significantly closer in weight to the weight of the female than larger males in trials that did not result in a mating. Larger males in trials that did not result in a mating had higher rates of aggressive stridulation than larger males that mated. Male weight is therefore important in mating success; fitness traits should theoretically show low genetic variability. However, significant heritability values were found for live weight, dry weight, head width, pronotum width and length, hind femur length and forewing length when estimated from the regression of offspring on mid-parent values, offspring and female and male values separately and full-sib correlations. The heritability of hind femur width was significant when estimated from the regression of offspring on male parent and from full-sib correlations. Heritability estimates of forewing length were significantly higher when estimated from the regression of offspring on female parent than when estimated from the regression of offspring on male parent. High phenotypic, genetic and environmental correlations were found between all pairs of traits. Data on male mating success and the heritability of fitness traits were discussed in terms of the maintenance of genetic variability.

The role of the dopaminergic system in the production of ultrasonic calls in adult rats /

Ultrasonic vocalizations (USV) are emitted by rats in a number of social situations such as aggressive encounters, during sexual behavior, and during play in young rats, situations which are predominantly associated with strong emotional responses. These USV typically involve two distinct types of calls: 22 kHz calls, which are emitted in aversive situations and 50 kHz calls, which are emitted in non-aversive, appetitive situation. The 50 kHz calls are the focus of the present study and to date both the glutamatergic and the dopaminergic systems have been independently implicated in the production of these 50 kHz calls. The present study was conducted to examine a possible relationship between glutamate (GLU) and dopamine (DA) in mediating 50 kHz calls. It was hypothesized that the dopaminergic system plays a mediating role in 50 kHz calls induced by injections ofGLU into the anterior hypothalamic/preoptic area (AHPOA) in adult rats. A total of 68 adult male rats were used in this study. Rats' USV were recorded and analyzed in five experiments that were designed to test the hypothesis: in experiment 1, rats were treated with systemic amphetamine (AMPH) alone; in experiment 2, intra- AHPOA GLU was pretreated with systemic AMPH; in experiment 3, intra-AHPOA GLU was pretreated with intra-AHPOA AMPH; in experiment 4, rats were treated with high and low doses of intra-AHPOA AMPH only; in experiment 5, rats were treated with systemic haloperidol (HAL) as a pretreatment for intra-AHPOA GLU. Analysis of the results indicated that AMPH has a facilitatory effect on 50 kHz USV and that a relationship between DA and GLU in inducing 50 kHz calls does exist. The effect, however, was only observed when DA receptors were antagonized with HAL and was not seen with systemic AMPH pretreatments of intra-AHPOA GLU. The DAGLU relationship at the AHPOA was unclear.

Perennial negotiations/elemental encounters autoethnographic perspectives on approaching food sovereignty

This thesis uses a multifaceted process to engage with the topic of food sovereignty in California. It employs diverse methods, including critical and creative prose, photography, autoethnographic mixed media, storytelling and poetry. I am particularly concerned with the " " challenges of approaching food sovereignty, a radical praxis that combines subsistence practices with anti-capitalist resistance, while in my own "skin," which is thoroughly embedded in white, urban, middle classed culture and in corltextualizing ecological relationshipslkinships via cultural, historical and economic trajectories. The project utilizes a processual methodlology drawing substantially from the work of Brian Massumi to explore these issues through four creative narrative pieces which coalesce around the elemental metaphors of air, fire, water and earth. Following Deleuze and Guatarri's concept ofrhizomatic plateaus, the thesis narratives are comprised of many non-hierarchical layers and can be read from many angles. Each is offered "in process" rather than as a finished piece, thus practically validating the concept of the ongoing work of research and suggesting the equally omnipresent possibility of change and mutation in the formation relationally based knowledges. Cultivating ecological ethic and healing on multisensory levels, as well as commitment to emergent and re-productivist worldviews are goals of this project's research.

Effects of low doses of quinpirole on production of 50 kHz vocalizations in Wistar rats

Rats emit two distinct types of ultrasonic vocalizations in adulthood: 22 kHz (aversive situation), and 50 kHz calls (appetitive situation). The present project is focussed on pharmacological studies of 50 kHz vocalizations. The 50 kHz calls are elicited from dopaminergic activation in the meso limbic pathway and are emitted in such appetitive situations as social contact(s), sexual encounters, food reward, etc. Eighty-five male rats were stereotaxically implanted with bilateral guide cannulae in the nucleus accumbens shell (A= 9.7, L= 1.2, V= 6.7). Quinpirole, a D2/D3 dopaminergic agonist, was injected in low doses to the nucleus accumbens shell in an attempt to elicit 50 kHz vocalizations. A dose response was obtained for the low dose range of quinpirole for six doses: 0.025 Jlg, 0.06 Jlg, 0.12 Jlg, 0.25 Jlg, 0.5 Jlg, and 1.0 Jlg. It was found that only application of the 0.25 Jlg dose of quinpirole and the 7 Jlg dose of amphetamine (positive control) significantly increased the total number of 50 kHz calls (p < 0.006 and p < 0.004 respectively); and particularly significantly increased the frequency modulated type of these calls (p < 0.01, and p < 0.006 respectively). In a double injection procedure, the dose of 0.25 Jlg quinpirole was antagonized with raclopride (D2 antagonist) or U99194A maleate (D3 antagonist) in an attempt to antagonize the response. The 0.25 Jlg dose of quinpirole was successfully antagonized by pre-treatment with an equimolar dose of U99194A maleate (p < 0.008) but not with raclopride. The 7Jlg amphetamine response was also antagonized with an equimolar dose of raclopride. Based on these results, it seems that low doses of quinpirole, particularly the 0.25 Jlg dose, are capable of increasing 50 kHz vocalizations in rats and do so by activation of the D3 dopamine receptor. This is not a biphasic response as seen with locomotor studies. Also noteworthy is the increase in frequency modulated 50 kHz calls elicited by the 0.25 Jlg dose of quinpirole indicating a possible increase in positive affect.
