Bonds away : baseball mythology and the 2007 home run chase

In 2007, Barry Bonds hit his 75 6th home run, breaking Hank Aaron's all-time record for most home runs in a Major League career. While it would be expected that such an accomplishment would induce unending praise and adulationfor the new record-holder, Bonds did not receive the treatment typically reserved for a beloved baseball hero. The purpose of this thesis is to assess media representations of the 2007 home run chase in order to shed light upon the factors which led to the mixed representations which accompanied BOlTds ' assault on Aaron's record. Drawingfrom Roland Barthes ' concept of myth, this thesis proposes that Bonds was portrayed in predominantly negative ways because he was seen as failing to embody the values of baseball's mythology. Using a qualitative content analysis of three major American newspapers, this thesis examines portrayals of Bonds and how he was shown both to represent and oppose elements from baseball's mythology, such as youth, and a distant, agrarian past. Recognizing the ways in which baseball is associated with American life, the media representations of Bonds are also evaluated to discern whether he was portrayed as personifYing a distinctly American set of values. The results indicate that, in media coverage of the 2007 home run chase, Bonds was depicted as a player of many contradictions. Most commonly, Bonds' athletic ability and career achievements were contrasted with unflattering descriptions of his character, including discussions of his alleged use of performance-enhancing substances. However, some coverage portrayed Bonds as embodying baseball myth. The findings contribute to an appreciation of the importance of historical context in examining media representations. This understanding is enhanced by an analysis of a selection of articles on Mark McGwire 's record-breaking season in 1998, and careful consideration of, and comparison to, the context under which Bonds performed in 2007. Findings are also shown to support the contemporary existence of a strong American baseball mythology. That Bonds is both condemned for failing to uphold the mythology and praised for personifYing it suggests that the values seen as inherent to baseball continue to act as an American cultural benchmark.

Comparison of strength gains over 13 and 26-weeks of resistance training in children

The primary aim of this study was to determine if there were significant strength gains achieved by children participating in the Hamilton Wentworth District School Board Sport Academy Program. The secondary aim was to determine if the children participating in the 26-week program achieved greater gains or if a plateau in strength adaptations occurred following the 13-week session. The tertiary aim was to determine if there were varying levels of response to the training stimulus between grade 7, grade 8 and grade 9 subjects. Ninety-eight (98) subjects completed a13-week RT program. 6RM strength testing of the chest press, seated row and leg press were conducted prior to the program. Subjects were tested following the 13-week training stimulus to determine if strength gains were achieved and to assess the variation in strength adaptations between the groups. Forty seven (47) subjects completed 26 weeks ofRT. Subjects' strength was tested prior to starting the program, at week 13 of the program and at week 26 of the program to determine the variation in adaptation over a 13 week program versus a 26- week RT program. There were significant (pand seated row exercises while grade 9 subjects showed significant gains across the 6RM seated row, chest press, and leg press measures.

Global migration : patriarchy, propoganda and the well- being of women and children

This critical analysis explores the conflicted position of women as ''trailing spouses" and the effects on families who relocate globally under the auspices of a multinational corporation, by utilizing a discursive analysis of two contemporary films and available literature. Current portrayals of women and children in contemporary media provide emotional yet conflicting images of the perfect woman, wife, mother, child and family. The basic tenets of a North American patriarchal economic system are being televised around the world. Technological advancements have made it possible to advertise political agendas on a global television screen. Much of what we see is propaganda couched in films and advertisements that are designed to romantic~e the practice of deriving profits from the unpaid labor of woman and invisibility of children and child rearing. I intend to show that the materiality of trailing a spouse globally conflicts with these romanticized images and supports feminist literature that asserts the notion that mothers and children are oppressed and managed for the benefit of capital.

Human skeletal muscle pyruvate dehydrogenase phosphatase activity and expression : the effect of aerobic capacity

Activation of pyruvate dehydrogenase (PDH), which converts pyruvate into acetyl-CoA, is accomplished by a pair of specific phosphatases (PDP 1 & 2). A cross-sectional study investigating the effect of aerobic capacity on PDP activity and expression found that: 1) PDP activity and PDP! protein expression were positively correlated with most aerobic capacity measures in males (n=lS), but not females (n=12); 2) only males showed a positive correlation between PDP activity and PDPl protein expression (r=0.47; p=O.05), indicating that the increase in PDP activity in males is largely explained by increased PDPl protein expression, but that females rely on another level for PDP activity regulation; and 3) PDP} and Ela protein expression increase in unison when expressed relative to the E2 core. These data suggest that with increased aerobic capacity there is an increased capacity for carbohydrate oxidation through PDH, via El a, and an increased ability to activate PDH, via PDP, when exercising maximally.

Iridium(I) complexes of phenanthroline-derived benzimidazolylidenes : synthetic, structural and catalytic studies

N-heterocyclic carbenes (NHCs) have undergone rapid development in recent years. Due to their strong a-electron donation and structural variability properties, NHCs are becoming a major class of ligands in organometallic chemistry. Compared with the other two types of NHCs (imidazolylidenes and imidazolinylidenes), benzimidazolylidenes have not been well represented. Limited synthetic approaches may impede the development ofbenzimidazolylidenes. This thesis is focused on the synthesis of phenanthroline-derived benzimidazolylidene ligands and their metal complexes. A series of benzimidazolylidene-iridium complexes were synthesized and characterized spectroscopically and crystallographic ally. All of the new complexes showed varying degrees of catalytic activity and enantioselectivity toward transfer hydrogenation and asymmetric hydrogenation. The best results were achieved in hydrogenation of methyl-2-acetamidoacrylate, which afforded (-)-(R)-methyl-2-acetamidopropanoate in 97% yield and 81 % ee.

Ontological constructivism : Negri and the philosophical foundations of a future communism

As we find in Empire and Multitude, Antonio Negri's political project IS a thoroughly Marxist analysis and critique of global or late capitalism. By modifying and updating Marx's conceptual tools, he is able to provide a clear account of capitalism's processes, its expanding reach, and the revolutionary potential that functions as its motor. By turning to Negri's philosophical works, however, we find that this political analysis is founded on a series of concepts and theoretical positions. This paper attempts to clarify this theoretical foundation, highlighting in particular what I term "ontological constructivism" - Negri's radical reworking of traditional ontology. Opposing the long history of transcendence in epistemology and metaphysics (one that stretches from Plato to Kant), this reworked ontological perspective positions individuals - not god or some other transcendent source - as the primary agents responsible for molding the ontological landscape. Combined with his understanding of kairos (subjective, immeasurable time), ontological constructivism lays the groundwork for opposing transcendence and rethinking contemporary politics.

Produced subjectivities and productive subjects : locating the potential of the self-reflective blog

Blogging software has popularly been used as a mode of writing about everyday life to interact with others. This thesis examines the political potentials that are opened up by self-reflective blogging. The self-reflective blog is a synergy of self-reflective practices and computer-mediated communication. A genealogy of the history of computer-mediated communication and various public self-reflective practices is conducted to uncover affect as the utility of various economies of subject production. Efforts made to blog-like the efforts made to interact online in other CMCs-are positioned as a kind of affective labor. Adapting Hardt and Negri's (2005) theorization of the multitude, whereby affective labor-the production of social relationshipsis a kind ofbiopolitical production, affect will be determined as a kind ofbiopolitical power that exists in everyday life.

Relative importance of body composition, osteoporosis- related behaviours and socioeconomic status on bone SOS in adolescent females

The purpose of this study was to examine the associations between bone speed of sound (SOS) and body composition, osteoporosis-related health behaviours, and socioeconomic status (SES) in adolescent females. A total of 442 adolescent females in grades 9-11 participated. Anthropometric measures of height, body mass, and percent body fat were taken, and osteo-protective behaviours such as oral contraceptive use (OC), physical activity and daily calcium intake were evaluated using self-report questionnaires. Bone SOS was measured by transaxial quantitative ultrasound (QUS) at the distal radius and mid-tibia. The results suggest that fat mass is a significant negative predictor of tibial SOS, while lean mass is positively associated with radial SOS scores and calcium intake was positively associated with tibial SOS scores (pand bone SOS. Therefore bone strength measured by QUS is reduced in adolescents with an increased fat mass, and influenced positively by OC use, calcium intake and lean mass.

(Re)Thinking bodies : Deleuze and Guattari's becoming- woman

Abstract (Re)thinking Bodies: Deleuze and Guattari 's becoming-woman seeks to explore the notion of becoming-woman, as put forth by Gilles Deleuze and Felix Guattari in their collaborative 1982 text, A Thousand Plateaus: Capitalism and Schizophrenia, and as received by such prominent feminist theorists as Rosi Braidotti and Elizabeth Grosz. Arguing that the fairly decisive repudiation of this concept by some feminist theorists has been based on a critical misunderstanding, this project endeavors to clarify becomingwoman by exploring various conceptions of the body put forth by Baruch de Spinoza, Friedrich Nietzsche and Simone de Beauvoir. These conceptions of the body are indispensible to an appreciation of Deleuze and Guattari's notion of a body lived on both an immanent and transcendent plane, which, in turn, is indispensable to an appreciation of the concept of becoming (and, in particular, the concept of becoming-woman) as intended by Deleuze and Guattari.

Scales, networks and uncertainty : an examination of environmental policy-making in Ontario

Through a case-study analysis of Ontario's ethanol policy, this thesis addresses a number of themes that are consequential to policy and policy-making: spatiality, democracy and uncertainty. First, I address the 'spatial debate' in Geography pertaining to the relevance and affordances of a 'scalar' versus a 'flat' ontoepistemology. I argue that policy is guided by prior arrangements, but is by no means inevitable or predetermined. As such, scale and network are pragmatic geographical concepts that can effectively address the issue of the spatiality of policy and policy-making. Second, I discuss the democratic nature of policy-making in Ontario through an examination of the spaces of engagement that facilitate deliberative democracy. I analyze to what extent these spaces fit into Ontario's environmental policy-making process, and to what extent they were used by various stakeholders. Last, I take seriously the fact that uncertainty and unavoidable injustice are central to policy, and examine the ways in which this uncertainty shaped the specifics of Ontario's ethanol policy. Ultimately, this thesis is an exercise in understanding sub-national environmental policy-making in Canada, with an emphasis on how policy-makers tackle the issues they are faced with in the context of environmental change, political-economic integration, local priorities, individual goals, and irreducible uncertainty.

Steeltown scene : genre, performance and identity in the alternative independent music scene in Hamilton, Ontario

This thesis examines the independent alternative music scene in the city of Hamilton, Ontario, also known, with reference to its industrial heritage, as "Steeltown." Drawing on the growing literature on the relationship between place and popular music, on my own experience as a local musician, direct observation of performances and of venues and other sites of interaction, as well as ethnographic interviews with scene participants, I focus on the role of space, genre and performance within the scene, and their contribution to a sense of local identity. In particular, I argue that the live performance event is essential to the success of the local music scene, as it represents an immediate process, a connection between performers and audience, one which is temporally rooted in the present. My research suggests that the Hamilton alternative music scene has become postmodern, embracing forms of "indie" music that lie outside of mainstream taste, and particularly those which engage in the exploration and deconstruction of pre-existing genres. Eventually, however, the creative successes of an "indiescene" permeate mass culture and often become co-opted into the popular music mainstream, a process which, in turn, promotes new experimentation and innovation at the local level.

The impact of wine closure and packaging type, and light and temperature exposure on the concentration of 3-alkyl-2 -methoxypyrazines and other key constituents of wine

3-alkyl-2-methoxypyrazines (MPs) are grape- and insect-derived odor-active compounds responsible for vegetative percepts that are detrimental to wine quality when elevated. This study tested both the effect of closure/packaging types and light/temperature storage conditions on MPs (isopropyl-, secbutyl-, and isobutyl-MP) in wine. An MP-emiched wine rapidly (after 140 hours) and significantly decreased in MP concentration after natural and synthetic cork contact (immersion of closures in wine). This decrease was greatest with synthetic closures (70% - 89% reduction) and secbutyl-MP. Subsequently storage trials tested the effects of commercial closure/packaging options (natural cork, agglomerate cork, synthetic corks, screwcaps and TetraPak® cartons) on MPs in MP-emiched Riesling and Cabernet Franc over 18 months. Regardless of packaging, isobutyl-MP was the most altered from bottling. Notably, all MP levels tended to decrease to the greatest extent in TetraPak® cartons (~34% for all MPs) and there was evidence of contribution ofisoproyl- and secbutyl-MP from cork-based closures (i.e. ~30% increase in secbutyl-MP after 6 months) or from an unidentified wine constituent. To test the effects of various light/temperature conditions (light exposed at ambient temperature in three different bottle hues, light excluded at ambient temperature and light excluded at a "cellar" temperature (14°C)), MP-emiched Riesling and Cabernet Franc were also analyzed for MP concentrations over 12 months. MPs did not vary consistently with light or temperature. Other odorants and physico-chemical properties were tested in all wines during storage trials and closely agree with previous literature. These results provide novel insights into MPs during ageing, interactions with packaging and storage conditions, and assist in the selection of storage conditions/packaging for optimal wine quality.

The role of intrapartum intravenous therapy and method of delivery on newborn weight loss : challenging the 7% rule

It is common practice to initiate supplemental feeding in newborns if body weight decreases by 7-10% in the first few days after birth (7-10% rule). Standard hospital procedure is to initiate intravenous therapy once a woman is admitted to give birth. However, little is known about the relationship between intrapartum intravenous therapy and the amount of weight loss in the newborn. The present research was undertaken in order to determine what factors contribute to weight loss in a newborn, and to examine the relationship between the practice of intravenous intrapartum therapy and the extent of weight loss post-birth. Using a cross-sectional design with a systematic random sample of 100 mother-baby dyads, we examined properties of delivery that have the potential to impact weight loss in the newborn, including method of delivery, parity, duration of labour, volume of intravenous therapy, feeding method, and birth attendant. This study indicated that the volume of intravenous therapy and method of delivery are significant predictors of weight loss in the newborn (R2=15.5, p<0.01). ROC curve analysis identified an intravenous volume cut-point of 1225 ml that would elicit a high measure of sensitivity (91.3%), and demonstrated significant Kappa agreement (p<0.01) with excess newborn weight loss. It was concluded that infusion of intravenous therapy and natural birth delivery are discriminant factors that influence excess weight loss in newborn infants. Acknowledgement of these factors should be considered in clinical practice.

The role of physical activity and perceived adequacy on cardiorespiratory fitness in children with developmental coordination disorder

Evidence suggests that children with developmental coordination disorder (DCD) have lower levels of cardiorespiratory fitness (CRF) compared to children without the condition. However, these studies were restricted to field-based methods in order to predict V02 peak in the determination of CRF. Such field tests have been criticised for their ability to provide a valid prediction of V02 peak and vulnerability to psychological aspects in children with DCD, such as low perceived adequacy toward physical activity. Moreover, the contribution of physical activity to the variance in V02 peak between the two groups is unknown. The purpose of our study was to determine the mediating role of physical activity and perceived adequacy towards physical activity on V02 peak in children with significant motor impairments. This prospective case-control design involved 122 (age 12-13 years) children with significant motor impairments (n=61) and healthy matched controls (n=61) based on age, gender and school location. Participants had been previously assessed for motor proficiency and classified as a probable DCD (p-DCD) or healthy control using the movement ABC test. V02 peak was measured by a progressive exercise test on a cycle ergometer. Perceived adequacy was measured using a 7 -item subscale from Children's Selfperception of Adequacy and Predilection for Physical Activity scale. Physical activity was monitored for seven days with the Actical® accelerometer. Children with p-DCD had significantly lower V02 peak (48.76±7.2 ml/ffm/min; p:50.05) compared to controls (53.12±8.2 ml/ffm/min), even after correcting for fat free mass. Regression analysis demonstrated that perceived adequacy and physical activity were significant mediators in the relationship between p-DCD and V02 peak. In conclusion, using a stringent laboratory assessment, the results of the current study verify the findings of earlier studies, adding low CRF to the list of health consequences associated with DCD. It seems that when testing for CRF in this population, there is a need to consider the psychological barriers associated with their condition. Moreover, strategies to increase physical activity in children with DCD may result in improvement in their CRF.

Toward a grounded theory of trigger events and leadership development in early adulthood

The purpose of this research study was to develop a conceptual model through the use of a grounded theory approach, which explains how trigger events are related to leadership development. Trigger events are experience that cause developmental growth and may result in an increased ability to lead (Luthans and Avolio (2003). In this study, there were two phases of data collection. First participants completed the Washington University Sentence Completion Test (WUSCT), where their respective leadership developmental stage was measured. Second, participants were involved in two in-depth interviews where an understanding was reached as to how various trigger events have impacted their leadership development. From these data, a conceptual model was developed to explain the relationship between trigger events and leadership development. Participants described trigger events as being important developmental periods, during which time they grew as people and became more capable leaders.
