Social physique anxiety across physical activity settings : a meta-analytical review

The purpose of this meta-analytic investigation was to review the empirical evidence specific to the effect of physical activity context on social physique anxiety (SP A). English language studies were located from computer and manual literature searches. A total of 146 initial studies were coded. Studies included in the meta-analysis presented at least one empirical effect for SPA between physical activity participants (i.e., athletes or exercisers) and non-physical activity participants. The final sample included thirteen studies, yielding 14 effect sizes, with a total sample size of 2846. Studies were coded for mean SPA between physical activity participants and non-physical activity participants. Moderator variables related to demographic and study characteristics were also coded. Using Hunter and Schmidt's (2004) protocol, statistical artifacts were corrected. Results indicate that, practically speaking, those who were physically active reported lower levels of SPA than the comparison group (dcorr = -.12; SDeorr.-=-;22). Consideration of the magnitude of the ES, the SDeorr, and confidence interval suggests that this effect is not statistically significant. While most moderator analyses reiterated this trend, some differences were worth noting. Previous research has identified SPA to be especially salient for females compared to males, however, in the current investigation, the magnitude of the ES' s comparing physical activity participants to the comparison group was similar (deorr = -.24 for females and deorr = -.23 for males). Also, the type of physical activity was investigated, and results showed that athletes reported lower levels of SP A than the comparison group (deorr = -.19, SDeorr = .08), whereas exercisers reported higher levels of SPA than the comparison group (deorr = .13, SDeorr = .22). Results demonstrate support for the dispositional nature of SP A. Consideration of practical significance suggests that those who are involved in physical activity may experience slightly lower levels of SPA than those not reporting physical activity participation. Results potentially offer support for the bi-directionality of the relationship between physical activity and SP A; however, a causality may not be inferred. More information about the type of physical activity (i.e., frequency/nature of exercise behaviour, sport classificationllevel of athletes) may help clarify the role of physical activity contexts on SPA.

Graffiti, memory and contested space : mnemonic initiatives following trauma and/or repression in Buenos Aires, Argentina

Graffiti, Memory and Contested Space: Mnemonic Initiatives Following Periods of Trauma and/or Repression in Buenos Aires, Argentina This thesis concerns the popular articulation ofmemory following periods or incidents of trauma in Argentina. I am interested in how groups lay claim to various public spaces in the city and how they convert these spaces into mnemonic battlegrounds. In considering these spaces of trauma and places of memory, I am primarily interested in how graffiti writing (stencils, spray-paint, signatures, etchings, wall-paintings, murals and installations) is used to make these spaces transmit particular memories that impugn official versions of the past. This thesis draws on literatures focused on popular/public memory. Scholars argue that memory is socially constructed and thus actively contested. Marginal initiatives such as graffiti writing challenge the memory projects of the state as well as state projects that are perceived by citizens to be 'inadequate,' 'inappropriate,' and/or as promoting the erasure of memory. Many of these initiatives are a reaction to the proreconciliation and pro-oblivion strategies of previous governments. I outline that the history of silences and impunity, and a longstanding emphasis on reconciliation at the expense of truth and justice has created an environment of vulnerable memory in Argentina. Popular memory entrepreneurs react by aggressively articulating their memories in time and in space. As a result of this intense memory work, the built landscape in Buenos Aires is dotted with mnemonic initiatives that aim to contradict or subvert officially sanctioned memories. I also suggest that memory workers in Argentina persistently and carefially use the sites of trauma as well as key public spaces to ensure official as well as popular audiences . The data for this project was collected in five spaces in Buenos Aires, the Plaza de Mayo, Plaza Congreso, La Republica Cromanon nightclub, Avellaneda Train Station and El Olimpo, a former detention centre from the military dictatorship.

The physiology of inscription : Foucault's genealogy as curative science

In ''Nietzsche, Genealogy, History," Foucault suggests that genealogy is a sort of "curative science." The genealogist must be a physiologist and a pathologist as well as an historian, for his task is to decipher the marks that power relations and historical events leave on the subjugated body; "he must be able to diagnose the illnesses of the body, its conditions of weakness and strength, its breakdowns and resistances, to be in a position to judge philosophical discourse." But this claim seems to be incongruent with another major task of genealogy. After all, genealogy is supposed to show us that the things we take to be absolute are in fact discontinuous and historically situated: "Nothing in man-not even his body-is sufficiently stable to serve as the basis for self-recognition or for understanding other men." If this is true, then the subjugated body can never be restored to a healthy state because it has no essential or original nature. There are no universal standards by which we can even distinguish between healthy and unhealthy bodies. So in what sense is genealogy to be a "curative science"? In my thesis, I try to elucidate the complex relationship between genealogy and the body. I argue that genealogy can be a curative science even while it "multiplies our body and sets it against itself." Ifwe place a special emphasis on the role that transgression plays in Foucault's genealogical works, then the healthy body is precisely the body that resists universal standards and classifications. If genealogy is to be a curative science, then it must restore to the subjugated body an "identity" that transgresses its own limits and that constitutes itself, paradoxically, in the very effacement of identity. In the first chapter of my thesis, I examine the body's role as "surface of the inscription of events." Power relations inscribe on and around the body an identity or subjectivity that appears to be unified and universal, but which is in fact disparate and historically situated. The "subjected" body is the sick and pathologically weak body. In Chapters 2 and 3, I describe how it is possible for the unhealthy body to become healthy by resisting the subjectivity that has been inscribed upon it. Chapter 4 explains how Foucault's later works fit into this characterization of genealogy

Heroes on the home front : heroism and virtue in post-9/11 American cinema /

This thesis is intended to contribute to critical discussion of the American male hero in mainstream American war and action films post September 11, 2001 . The thesis investigates how these heroes' behaviour echoes a patriotic, conservative construction of the modern American as created through speeches given by George W. Bush in the wake of the events of September 11, 2001 . The thesis examines the hero in six primary sources: the war films We Were Soldiers, Behind Enemy Lines and The Great Raid and the action films Collateral Damage, Man on Fire and The Punisher. By analyzing the ideological subtext, political content, visual strategies and generic implications of the films, as well as the binary constructions of a selection of Bush speeches, and by reviewing historical representations of American male heroes on film produced in the wake of political events, the thesis concludes that the six films mobilize the USA's conservative viewpoint towards war and military action, and in concert with the speeches, contribute to an ongoing militarization of visual culture. Both systems echo a dangerous ideological fantasy of American history, life and patriotism.

What's the difference under the gown? : new professors' development as university teachers

This study explores how new university teachers develop a teaching identity. Despite the significance ofteaching, which usually comprises 40% of a Canadian academic's workload, few new professors have any formal preparation for that aspect of their role. Discipline-specific education for postsecondary professors is a well-defined path; graduates applying for faculty positions will have the terminal degree to attest to their knowledge and skill conducting research in the discipline. While teaching is usually given the same workload balance as research, it is not clear how professors create themselves as teaching professionals. Drawing on Kelly's (1955) personal construct theory and Kegan's (1982, 1994) model ofdevelopmental constructivism through differentiation and integration, this study used a phenomenographic framework~(Marton, 1986, 1994; Trigwell & Prosser, 1996) to investigate the question of how new faculty members construe their identity as university teachers. Further, my own role development as researcher was used as an additional lens through which to view the study results. The study focused particularly on the challenges and supports to teaching role development and outlines recommendations the participants made for supporting other newcomers. In addition, the variations and similarities in the results suggest a developmental model to conceptions ofteaching roles, one in which teaching, research, and service roles are viewed as more integrated over time. Developing a teacher identity was seen as a progression on a hierarchical model similar to Maslow's (1968) hierarchy of needs.

Analysis of the feeding behaviour of the mosquito Culex pipiens L. (Diptera: Culicidae) in relation to West Nile virus

The goal ofthis literature review is to inform the reader on several aspects of West Nile Virus (WNV) transmission by its mosquito vector, Culex pipiens and to elucidate how Cx. pipiens and WNV are intertwined. The first few sections of the literature review describe the life cycle and blood feeding behaviours ofmosquitoes so that baseline data ofmosquito biology are established. In addition to explaining how and why a mosquito blood feeds, the section on "Blood Meal Analysis" describes the different methods for determining the vertebrate source of mosquito blood meals and a brief history of these testing methods. Since this thesis looks at the feeding behaviour of Cx. pipiens, it is important to know how to determine what they are feeding upon. Discussion on other mosquito-borne diseases related to WNV gives a broader perspective to the thesis, and examines other diseases that have occurred in Ontario in the past. This is followed by background information on WNV and theories on how this virus came to North America and how it relates to Cx. pipiens. The final sections discuss Cx. pipiens and give background information to how this species of mosquito exists and behaves within North America.

Quaternary geology of the Campbellford, Trenton, Consecon, Tweed, Belleville, Wellington, Sydenham, Bath, and Yorkshire Island map-areas, Ontario /

Sediment relationships observed during geological mapping in southeastern Ontario indicate a relatively simple deglaciation history for the area during late Wisconsin time. The ice from the north (part of the Lake Simcoe lobe) and the Lake Ontario ice lobe, which were coalesced during most of late Wisconsin time, initially separated along the crest of the Oak Ridges Moraine. Available data indicate that the Oak Ridges Moraine is composed primarily of sediments pre-late Wisconsin in age capped by late Wisconsin till and interlobate deposits. Retreat of the northern ice was relatively steady and resulted in the deposition of the Dummer Moraines, a facies of the drumlinized till to the south. Retreat of the Lake Ontario ice lobe into the Lake Ontario basin was interrupted by a re-advance which covered the southeastern half of the map area. The northern ice had already retreated from the area by this time. The Lake Ontario lobe was fed through the St. Lawrence Valley, indicating that the Ottawa Valley was ice filled at this time. High level glacial lakes fronted the ice during deglaciation. These waters quickly fell to low levels as the ice retreated from the St. Lawrence Valley, opening lower outlets.

Contributing factors to women's sustained participation on varsity athletic teams /

This study explores the factors contributing to female athletes' sustained participation on varsity athletic teams. Ten open-ended interviews were conducted with female varsity athletes to investigate what contributes to their sustained involvement in sport until and throughout university. Each interview was transcribed and then coded for emergent themes and categories. Grounded in the data were themes such as socialization, support systems, motivational factors, passion, opportunity to play, and physical ability. The results demonstrate that for women to continue to participate in sport, a positive learning environment must be created in which the women may share and grow in their experiences as a collective whole. Relationships are a dominant factor for sustained participation in athletics. There are a number of questions presented that may lead to further research, specifically in regard to what physical educators and coaches may implement in an educational, athletic, or practice setting to enhance females' positive experiences.

Teamwork and leadership : competitive youth soccer as a context for positive youth development

The purpose of this study was to examine processes and interactions that characterized positive developmental experiences in sport. A highly competitive and reputable U-17 girls' soccer team was chosen for the study through purposeful sampling, providing an information rich case from which data could be derived (Patton, 2002). Seventeen players and three coaches participated in this study. Based on an ethnographic methodology data were collected via observations and both informal and formal semi-structured interviews. Tlie data were coded according to the three procedures outlined by Seidel and Kelle (1995): a) noticing relevant phenomena, b) collecting examples of those phenomena, and c) analyzing those phenomena in order to find commonalities, differences, patterns and structures. Significant events and underlying themes were recounted chronologically through a collection of vignettes, aimed to provide a contextual lens for the reader. Results revolved around two prominent themes: Teamwork and leadership. These were closely related concepts that required players to demonstrate a wide range of developmental skills for the team to move collectively towards their end goal. Furthermore, teamwork and leadership experiences took both desirable and undesirable forms. For example, at the beginning of the season competition existed amongst the players at the expense of teamwork and leadership. As the season progressed the pursuit of a shared goal allowed the players to view each other as collaborators and teamwork and leadership skills became increasingly evident. At times, however, success on the field was prioritized above maintaining relationships off the field, requiring the coaches to intervene and re-establish equilibrium.

The social consequences of mild head injury and executive dysfunction /

Mild head injury (MHI) is a serious cause of neurological impairment as is evident by the substantial percentage (15%) of individuals who remain symptomatic at least 1-year following "mild" head trauma. However, there is a paucity of research investigating the social consequences following a MHI. The first objective of this study was to examine whether measures of executive functioning were predictive of specific forms of antisocial behaviour, such as reactive aggression, impulsive antisocial behaviour, behavioural disinhibition, and deficits in social awareness after controlling for the variance accounted for by sex differences. The second objective was to investigate whether a history of MHI was predictive of these same social consequences after controlling for both sex differences and executive functioning. Ninety university students participated in neuropsychological testing and filled out self-report questionnaires. Fifty-two percent of the sample self-reported experiencing a MHI. As expected, men were more reactively aggressive and antisocial than women. Furthermore, executive dysfunction predicted reactive aggression and impulsive antisocial behaviour after controlling for sex differences. Finally, as expected, MHI status predicted reactive aggression, impulsive antisocial behaviour, and behavioural disinhibition after controlling for sex and executive fimctioning. MHI status and executive functioning did not predict social awareness or sensitivity to reward or punishment. These results suggest that incurring a MHI has serious social consequences that mirror the neurobehavioural profile following severe cases of brain injury. Therefore, the social sequelae after MHI imply a continuum of behavioural deficits between MHI and more severe forms of brain injury.

The shifting terrain of feminist theory and activism : university-based women's centres and third wave feminism

This thesis, based on the results of an organizational ethnography of a university-based feminist organization in Southern Ontario (the Centre), traces how third wave feminism is being constituted in the goals, initiatives, mandate, organizational structure, and overall culture of university-based feminist organizations. I argue that, from its inception, the meanings and goals of the Centre have been contested through internal critique, reflection, and discussion inspired by significant shifts in feminist theory that challenge the fundamental principles of second wave feminism. I identify a major shift in the development and direction of the Centre that occurs in two distinct phases. The first phase of the shift occurs with the emergence of an antioppression framework, which broadens the Centre's mandate beyond gender and sexism to consider multiple axes of identity and oppression that affect women's lives. The second phase of this shift is characterized by a focus on (trans) inclusion and accessibility and has involved changing the Centre's name so that it is no longer identified as a women's centre in order to reflect more accurately its focus on mUltiple axes of identity and oppression. Along with identifying two phases of a major shift in the direction of the Centre, I trace two discourses about its development. The dominant discourse of the Centre's development is one of progress and evolution. The dominant discourse characterizes the Centre as a dynamic feminist organization that consistently strives to be more inclusive and diverse. The reverse discourse undermines the dominant discourse by emphasizing that, despite the Centre's official attempts to be inclusive and to build diversity, little has actually changed, leaving women of colour marginalized in the Centre's dominant culture of whiteness. This research reveals that, while many of their strategies have unintended (negative) consequences, members of the Centre are working to build an inclusive politics of resistance that avoids the mistakes of earlier feminist movements and organizations. These members, along with other activists, actively constitute third wave feminism in a process that is challenging, contradictory, and often painful. A critical analysis of this process and the strategies it involves provides an opportunity for activists to reflect on their experiences and develop new strategies in an effort to further struggles for social justice and equity.

Exploring domination and subordination in high school physical education /

This is a critical qualitative inquiry into secondary school students' experiences of power relations within physical activity and physical education settings. More specifically the study examines the reproduction ofpower relations through the use of domination and subordination in physical activity and physical education. This study will attempt to understand power relations that take place between and among students and between teachers and students and how certain sports or activities reinforce power relationships within the gymnasium. Thirty eight first and second year university students completed a questionnaire which asked them to reflect upon their high school physical education experiences. Feedback fi*om the questionnaires described that highly skilled male students benefit the most fi-om high school physical education and receive more power and privilege when compared to lesser skilled students.

Bone properties and skeletal maturity in adolescent males, as assessed by quantitative ultrasound

ABSTRACT Background: Previous studies have implied that weight-bearing, intense and prolonged physical activities optimize bone accretion during the grow^ing years. The majority of past inquiries have used dual-energy X-ray absorptiometry (DXA) to examine bone strength and hand-wrist radiography to determine skeletal maturity in children. Recently, quantitative ultrasound (QUS) technologies have been developed to examine bone properties and skeletal maturity in a safe, noninvasive and cost-effective manner. Objective: The purpose of this study was to compare bone properties and skeletal maturity in competitive male child and adolescent athletes with minimallyactive, age-matched controls, using QUS technology. >. Methods: In total, 224 males were included in the study. The 115 pre-pubertal boys aged 10-12 years consisted of control, minimally-active children (n=34), soccer players (n=26), gymnasts (n=25) and hockey players (n=30). In addition, the 109 late-pubertal boys aged 14-16 years consisted of control, minimally-active adolescents (n=31), soccer players (n=30), gymnasts (n=17) and hockey players (n=31). The athletic groups were elite level players that predominantly trained year-round. Physical activity, nutrition and sports participation were assessed with various questionnaires. Anthropometries, such as height, weight and relative body fat percentage (BF%) were assessed using standard measures. Skeletal strength and age were evaluated using bone QUS. Lastly, salivary testosterone (sT) concentration was measured using Radioimmunoassay (RIA). Results: Within each age group, there were no significant differences between the activity groups in age and pubertal stage. An age effect was apparent in all variables, as expected. A sport effect was noted in all physical characteristics: the child and adolescent gymnasts were shorter and lighter than other sports groups. Adiposity was greater in the controls and in the hockey players. All child subjects were pubertal stage (fanner) I or II, while adolescent subjects were pubertal stage IV or V. There were no differences in daily energy and mineral intakes between sports groups. In both age groups, gymnasts had a higher training volume than other athletic groups. Bone speed of sound (50s) was higher in adolescents compared with the children. Gymnasts had signifieantly higher radial 50S than controls, hockey and soccer players in both age cohorts. Hockey athletes also had higher radial 50S than controls and soccer players in the child and adolescent groups, respectiyely. Child gymnasts and soccer players had greater tibial 50S compared with the hockey players and control groups. Likewise, adolescent gymnasts and soccer players had higher tibial SoS compared with the control group. No interaction was apparent between age and type of activity in any of the bone measures. » Lastly, maturity as assessed by sT and secondary sex characteristics (Tanner stage) was not different between sports group within each age group. Despite the similarity in chronological age, androgen levels and sexual maturity, differences between activity groups were noted in skeletal maturity. In the younger group, hockey players had the highest bone age while the soccer players had the lowest bone age. In the adolescent group, gymnasts and hockey players were characterized by higher skeletal maturity compared with controls. An interaction between the age and sport type effects was apparent in skeletal maturity, reflecting the fact that among the children, the soccer players were significantly less mature than the rest of the groups, while in the adolescents, the controls were the least skeletally mature. Summary and Conclusions: In summary, radial and tibial SOS are enhanced by the unique loading pattern in each sport (i.e, upper and lower extremities in gymnastics, lower extremities in soccer), with no cumulative effect between childhood and adolescence. That is, the effect of sport participation on bone SOS was apparent already among the young athletes. Enhanced bone properties among athletes of specific sports suggest that participation in these sports can improve bone strength and potential bone health.

Resilience factors of university and college students with learning disabilities as revealed through retrospective interviews /

This qualitative study examined resilience factors of eight university and college students with learning disabilities as revealed through retrospective interviews. This study has added to the existing literature surrounding resilience especially as it relates to individuals with learning disabilities. This study may provide additional insight into the emotional impacts of repeated and chronic risks on students with learning disabilities. The major themes that emerged using the interpretive phenomenological analysis method (Smith & Osborn, 2003) were organized under these four major headings: Challenges and Obstacles, Surviving Challenges, Supportive Conditions, and A Journey of Discovery and Hope. An adaptation of the listening guide analytical method (Gilligan, Spencer, Weinberg, & Bertsch, 2003) was also utilized and offered a more personal depiction of the participants and an exploration of the unique contributions their stories made to this study. Specifically, a theme of feeling trapped/wanting to escape emerged as a reaction to adversity faced during elementary school years. Furthennore, this study has demonstrated that for several of the participants, the benefits of positive outlets extended beyond nurturing areas of strength and self-esteem to also include the provision of a short respite from their challenges and enhanced feelings of overall well-being. Additionally, this study may add to the existing literature surrounding character traits evident in resilient students, specifically highlighting the significance of optimism and selfacceptance.
