This qualitative study examined the effects of hospital restructuring on a group of nurses at a community hospital. Eleven nurses were asked questions in order to gain insight into their experience in this situation. Ten of these participants were female, and one was male. The intent was to gather information about how restructuring has affected their lives, including, their motivational factors and barriers to participation in continuing education, and their descriptions of their workplace environment. Audiotaped interviews were conducted on two occasions to obtain this data. Emergent themes included the nurses' comments about continuing education, motivational factors, barriers that included geography and time, reactions of co-workers, restructuring, the College of Nurses' Quality Assurance Program including peer feedback, and performance appraisals. The literature review compares the barriers and motivational factors to the previous research findings. Thus, this study gave voice to the experience of this group of nurses, working in a healthcare setting that is involved in restructuring. This information is important to the healthcare system, since many areas are involved in restructuring. The whole process, if it is to be successful, depends on the frontline workers, namely the nurses. Thus, if there is anything to be learned from this group of people, that could be used to improve this progression, everyone would benefit from this information, were it to be implemented. Everyone is a stakeholder in the quality of healthcare in our province. The frontline workers are the ones that hold the vantage point to be able to provide suggestions for the changes needed to successful. These nurses are not just motivated by work issues however, and educating them and motivating them will also improve the care provided through increased knowledge and enhanced self-esteem.

Abstract: In Imperial Eyes Mary Louise Pratt (1992: 7, emphasis original) defines autoethnography as "instances in which colonized subjects undertake to represent themselves in ways that engage with the colonizer's own terms ... in response to or in dialogue with . . . metropolitan representations." Although Pratt's conceptualization of autoethnography has much to offer post-colonial studies, it has received little attention in the field. In this thesis, I interrogate Pratt's notion of autoethnography as a theoretical tool for understanding the self-representations of subordinate peoples within transcultural terrains of signification. I argue that autoethnography is a concept that allows us to move beyond some theoretical dualisms, and to recognize the (necessary) coexistence of subordinate peoples' simultaneous accommodation of and resistance to dominant representations of themselves. I suggest that even when autoethnographic expressions seem to rely on or to reproduce dominant knowledges, their very existence as speech acts implicitly resists dominant discourses which objectify members of oppressed populations and re-create them as Native Informants. I use Pratt's concept to analyze two books by Islamic feminist sociologist Fatima Memissi. Memissi's Dreams ofTrespass and Scheherazade Goes West illustrate the simultaneity of accommodation and disruption evident in autoethnographic communication. Across the two books, Memissi shows herself renegotiating the discourses which discipline her (and her speech). She switches back and forth between the positions of reader and author, demonstrates the reciprocity of the disciplinary gaze (she looks back at her dominants, reading their own reading of her representation of her social group), and provides a model of autoethnographic dialogue.

The deoxy derivative of pancratistatin 1.10 was prepared in good yield through the use of a [4+2] Diels-Alder cycloaddition and Bischler-Napieralski cyclization approach. The Bischler-Napieralski cyclization was shown to yield two additional side products 2.9, 2.10, however, under slightly modified hydrolysis conditions, the tetracyclic product 2.11 was obtained exclusively in greater than 84% yield. Initial screening of the di-hydroxylatgd derivative, and the other complementary pair analogue 1.10' previously prepared in our laboratories gave interesting results. Both of these compounds were shown to exhibit cytostatic activity; the mono-alcohol was marginally active while the di-hydroxylated analogue proved to be more potent although one to two magnitudes less potent than pancratistatin itself Human tumour cell line assay results indicated that the di-hydroxylated derivative exhibited selective cytotoxic inhibition in the following cell lines: non-small cell lung cancer line NCI-H226 (ED50 - 0.65 ^g/mL), leukemia cell lines CCRF-CEM (ED30 = 0.55 Hg/mL) and HL-60(TB) (ED50 = 0.89^ig/mL). Our results demonstrated that the pharmacophore is not a mono-alcohol, and that the minimum pharmacophore contains the hydroxyl group at the C4 position in addition to either, or both, of the hydroxyl groups present at C2 and C3.' The minimum pharmacophore has been narrowed to only three possibilities which are current synthetic targets in several research groups. The controlled Grignard addition to the tartaric acid derived bis-Weinreb amide 1.25 afforded a direct entry to a host of 1,4-diflferentiated tartaric acid derived intermediates (2.12-2.18). This potentially usefiil methodology was demonstrated through the efficient synthesis of the naturally occurring lactone 2.23, which bears the inherent syn-dio\ subunit. Based on this result, a similar approach to the synthesis of syn-dio\ bearing natural products looks very promising? A direct 2,3-diol desymmetrization method using TIPS-triflate was shown to be effective on the selective differentiation of Z,-methyl tartrate (and diisopropyl tartrate). The mono-silyl-protected intermediates 2.31 also proved to be useful when they were selectively differentiated at the 1,4-carboxyl position (2.35, 2.36) through the use of a borohydride reducing agent. Furthermore, the mono-silyl-protected derivative underwent periodate cleavage affording two synthetically useful a,P-unsaturated esters 2.43, 2.44, with one of esters being obtained via a silyl-migration method.''

This study explored the concept of a spiritual retreat for frontline employees of a large corporate call centre. During a 1 day retreat, 4 call centre employees were introduced to various meditation and retreat activities. Follovsdng the retreat the participants were asked to incorporate the various meditations and activities into their workplace. The participants kept journals throughout the study in an effort to determine what occurred when these practices were transferred from the retreat setting to the workplace. This study examined how a working spirituality enhances one's sense of fulfillment, defined by certain critical elements: relationship, awareness, ritual, internal commitment, and choice. Although the retreat was a successful means of exploring these elements, the degree to which each employee could benefit from them was determined by the extent of their internal commitment not only to themselves, but also to their jobs.

All-electron partitioning of wave functions into products ^core^vai of core and valence parts in orbital space results in the loss of core-valence antisymmetry, uncorrelation of motion of core and valence electrons, and core-valence overlap. These effects are studied with the variational Monte Carlo method using appropriately designed wave functions for the first-row atoms and positive ions. It is shown that the loss of antisymmetry with respect to interchange of core and valence electrons is a dominant effect which increases rapidly through the row, while the effect of core-valence uncorrelation is generally smaller. Orthogonality of the core and valence parts partially substitutes the exclusion principle and is absolutely necessary for meaningful calculations with partitioned wave functions. Core-valence overlap may lead to nonsensical values of the total energy. It has been found that even relatively crude core-valence partitioned wave functions generally can estimate ionization potentials with better accuracy than that of the traditional, non-partitioned ones, provided that they achieve maximum separation (independence) of core and valence shells accompanied by high internal flexibility of ^core and Wvai- Our best core-valence partitioned wave function of that kind estimates the IP's with an accuracy comparable to the most accurate theoretical determinations in the literature.

National governments, the United Nations, and other organizations have deemed sport and other means of physical activity such as recreation, games and play for development a useful means for addressing a wide range of problems in communities and more specifically, providing youth with an opportunity to experience the benefits of physical activity. There is a need for research that furthers our understanding of how participants experience these programs. Specifically, the purpose of this study, was to better understand the lived experiences of the participants in a YMCA camp program that integrated physical activity and play for the specific development of poor youth street workers. A phenomenological approach infonned by a critical perspective (Creswell, 2003; Rossman & Rallis, 2003) was used. The study took place through the Asociaci6n Cristiana de J6venes de Costa Rica (ACJ) in Central America. The focus was on a camp program and the lived experiences of six purposefully chosen, youth street workers between the ages of 13-17. Their experiences were explored through semi-structured interviews. Other data that fonn the study include: field notes, observations, a reflexive journal and document analysis. The findings that emerged from the data include main themes of relationships, poverty, personal change and empowennent. For many youth, the ACJ is a relatively safe place to play, to "detach," their minds, to "distract" and "disorient" themselves from their dysfunctional families, violent neighbourhood, the poverty they live in, and from the necessity of having to work in the street to supplement the family income. Although many studies have shown that programs that include physical activity, play and/or sport have a positive impact on youth with regard to healthy development and improvements in well-being, there has been little work done to address the voices and experiences of the youth that participate in these programs. Using an interpretive-critical approach, this study focused on the participants' personal backgrounds, their experiences within the program and their critical reflections on the program. This study draws from a phenomenological philosophy and method to report findings from participants in an ACJ program in Costa Rica. This research shows how these youth were given the opportunity to use the program and the ACJ property as a relatively safe place to play, to behave like the youth they are, to establish and maintain their friendship networks, and develop empathy and conflict resolution skills. The fmdings from this study reveal how by participating in the ACJ program they each described a personal change, wherein they felt empowered to learn they could positivel y control themselves and as a result positively affect their own futures. These fmdings contribute knowledge surrounding the lived experiences of youth in developmental programs that use physical activity.

In 2002, The Ontario Federation of School Athletic Associations (OFSAA) identified that in providing extracurricular sport programs schools are faced with the 'new realities' of the education system. Although research has been conducted exploring the pressures impacting the provision of extracurricular school sport (Donnelly, Mcloy, Petherick, & Safai, 2000), few studies within the field have focused on understanding extracurricular school sport from an organizational level. The focus of this study was to examine the organizational design (structure, systems, and values) of the extracurricular sport department within three Ontario high schools, as well as to understand the context within which the departments exist. A qualitative multiple case study design was adopted and three public high schools were selected from one district school board in Ontario to represent the cases under investigation. Interviews, observations and documents were used to analyze the extracurricular sport department design of each case and to better understand the context within which the departments exist. As the result of the analysis of the structure, systems and values of each case, two designs emerged- Design KT1 and Design KT2. Differences in the characteristics of design archetype KT1 and KT2 centered on the design dimension of values, and therefore this study identified that contrasting organizational values reflect differences in design types. The characteristics of the Kitchen Table archetype were found to be transferable to the sub-sector of extracurricular school sport, and therefore this research provides a springboard for further research in organizational design within the education sector of extracurricular high school sport. Interconnections were found between the data associated with the external and internal contexts within which the extracurricular sport departments exist. The analysis of the internal context indicated the important role played by organizational members in shaping the context within which the departments exist. The analysis of the external context highlighted the institutional pressures that were present within the education environment. Both political and cultural expectations related to the role of extracurricular sport within schools were visible and were subsequently used by the high schools to create legitimacy and prestige, and to access resources.

There has been and will continue to be substantial debate over how the international system can best be characterized. The objective of this paper is to demonstrate that the international system can best be characterized by the essential features of realism, but the use of realist policy prescriptions are inadequate when applied independently to deal with the threat of terrorism as it exists today. In order to demonstrate this an examination of realism in the international system, U.S. foreign policy, and case analysis of Afghanistan and Iraq will be undertaken to demonstrate that although realist policy prescriptions do have a role in dealing with modem transnational security threats, these prescriptions on their own are inadequate when dealing with terrorism.

Although capacity has been used in recent federal government accords and policies related to the voluntary and amateur sport sectors, there is little consensus over the meaning of the term. Consequently, the purpose of this qualitative case study was to explore the concept of organizational capacity within a temporary voluntary sport organization. Specifically, the nature of organizational capacity was examined within the case of the Volunteers Division of the 2005 Canada Summer Games (CSG) Host Society. Data were collected from executive planning and middle management CSG volunteers through the use of a variety of methods: verbal journals, interviews, observations, documents and a focus group. Findings indicated several challenges associated with the volunteer management model utilized by the host society, varying levels of importance among six elements of capacity, and key aspects of the relationship between organizational capacity and transformational development. Implications focused upon the importance of highlighting individuals rather than the organizational as a whole in order to build capacity, and utilizing a brain or hybrid brain-machine organizational form to enhance capacity. Recommendations are provided for both the Canada Games Council and Canada Games host societies.

In the past two decades numerous programs have emerged to treat individuals with developmental disabilities who have sexual offending behaviours. There has, however been very few studies that systematically examine the effectiveness of long term treatment with this population. The present research examines the therapeutic outcomes of a multi-modal behaviour approach with six individuals with intellectual disabilities previously charged with sexual assault. The participants also exhibited severe behavioural challenges that included verbal aggression, physical aggression, destruction and self-injury. These six participants (5 males, 1 female) were admitted to a Long Term Residential Treatment Program (LTRTP), due to the severity of their behaviours and due to their lack of treatment success in other programs. Individualized treatment plans focused on the reduction of maladaptive behaviours and the enhancing of skills such as positive coping strategies, socio-sexual knowledge, life skills, recreation and leisure skills. The treatment program also included psychiatric, psychological, medical, behavioural and educational interventions. The participants remained in the Long Term Residential Treatment Program (LTRTP) program from 181 to 932 days (average of 1.5 years). Pre and post treatment evaluations were conducted using the following tools: frequency of target behaviours, Psychopathology Inventory for Mentally Retarded Adults (PIMRA), Emotional Problems Scale (EPS), Socio-Sexual Knowledge and Attitudes Assessment Tool (SSKAAT-R) and Quality of Life Questionnaire (QOL-Q). Recidivism rates and the need for re-hospitalization were also noted for each participant. By offering high levels of individualized interventions, all six participants showed a 37 % rate of reduction in maladaptive behaviours with zero to low rates of inappropriate sexualbehaviour, there were no psychiatric hospitalizations, and there was no recidivism for 5 of 6 participants. In addition, medication was reduced. Mental health scores on the PIMRA were reduced across all participants by 25 % and scores on the Quality of Life Questionnaire increased for all participants by an average of 72 %. These findings add to and build upon the existing literature on long term treatment benefits for individuals with a intellectual disability who sexually offend. By utilizing an individualized and multimodal treatment approach to reduce severe behavioural challenges, not only can the maladaptive behaviours be reduced, but adaptive behaviours can be increased, mental health concerns can be managed, and overall quality of life can be improved.

By relying on existing cultural models, the Victorian spa promoted health and wellness. Advertising, together with other forms of promotion, strengthened the legitimacy of its claims to cure a variety of health problems. By the use of some links to science and a mystical folk belief about the efficacy of the local mineral waters, three spas emerged in St.Catharines: the Stephenson House, the WeIland House, and the Springbank. As the twentieth century approached, the spa movement declined and institutionalized medicine struggled to establish a monopoly on health care. This thesis argues that the health spas in St. Catharines occupied that transitional space in nineteenth century medicine between home remedy and hospital. The interplay between scientific discovery and business enterprise produced a climate in which the Victorian health resort flourished. This phenomenon, combined with the various maladies brought on by industrialization, nineteenth-century lifestyle, and the absence of medical options, created a surge in the popularity of health spas and mineral spring therapies. By the tum of the twentieth century, interest in mineral water treatments had declined. The health resorts that had blossomed between 1850 and 1899 began to experience a serious decrease in business. This popular movement became outmoded in the face of emerging medical and scientific knowledge. In St. Catharines, the last resort to remain standing, the WeIland House, finished out the city's spa era as a hospital.

Autism is a developmental disorder that is characterized by abnonnal social interactions and communications as well as repetitive and restricted activities and interests. There is evidence of a genetic component, as 5% of younger siblings are diagnosed if their older sibling has been diagnosed. Autism is generally not diagnosed until age 3 at the earliest, yet it has been shown that early intervention for children with autism can greatly increase their functioning. Because of this, it is important that symptoms of autism are identified as early as possible so that diagnosis can occur as soon as possible to allow these children the earliest intervention. This thesis was divided into two parts. The first looked at the psychometrics of two proposed measures, the Parent Observation Checklist (POC), administered monthly, and the Infant Behavior Summary Evaluation (mSE), administered bimonthly, to see if they can be used with the infant population to identify autistic symptoms in infants who are at high risk for autism or related problems because they have an older sibling with autism. Study 1 reported acceptable psychometric properties of both the POC and IBSE in terms of test-retest reliability, internal consistency, construct validity and predictive validity. These results provide preliminary evidence that parent report measures can help to detect early symptoms of ASD in infants. The POC was shown to differentiate infants who were diagnosed from a matched group that was not diagnosed by 3 years of age. The second part of this thesis involved a telephone interview of parents who reported developmental and/or behavior problems in their high-risk infants that may be early signs of Autism Spectrum Disorder (ASD). During the interview, a service questionnaire was administered to see what interventions (including strategies recommended by the researchers) their at risk infants and affected older siblings were receiving, how satisfied the parents were with them and how effective they felt the interventions were. 3 Study 2 also yielded promising results. Parents utilized a variety of services for at risk infants and children with ASD. The interventions included empirically validated early intervention (e.g., ABA) to non-empirically validated treatments (e.g., diet therapy). The large number of nonempirically validated treatments parents used was surprising, yet parents reported being involved and satisfied, and thought that the services were effective. Parents' perceptions of their stress levels went down slightly and feelings of competence rose when they accessed services for their infants. Overall, the results of this thesis provide new evidence that parent-report methods hold promise as early detection instruments for ASD in at-risk infants. More research is needed to further validate these instruments as well as to understand the variables related to the parents' choice of early intervention for their at risk and affected children.

The oscillation of neuronal circuits reflected in the EEG gamma frequency may be fundamental to the perceptual process referred to as binding (the integration of various thoughts and perceptions into a coherent picture). The aim of our study was to expand our knowledge of the developmental course ofEEG gamma in the auditory modality. 2 We investigated EEG 40 Hz gamma band responses (35.2 to 43.0 Hz) using an auditory novelty oddball paradigm alone and with a visual-number-series distracter task in 208 participants as a function of age (7 years to adult) at 9 sites across the sagital and lateral axes (F3, Fz, F4, C3, Cz, C4, P3, Pz, P4). Gamma responses were operationally defined as change in power or a change in phase synchrony level from baseline within two time windows. The evoked gamma response was defined as a significant change from baseline occurring between 0 to 150 ms after stimulus onset; the induced gamma response was measured from 250 to 750 ms after stimulus onset. A significant evoked gamma band response was found when measuring changes in both power and phase synchrony. The increase in both measures was maximal at frontal regions. Decreases in both measures were found when participants were distracted by a secondary task. For neither measure were developmental effects noted. However, evoked gamma power was significantly enhanced with the presentation of a novel stimulus, especially at the right frontal site (F4); frontal evoked gamma phase synchrony also showed enhancement for novel stimuli but only for our two oldest age groups (16-18 year olds and adults). Induced gamma band responses also varied with task-dependent cognitive stimulus properties. In the induced gamma power response in all age groups, target stimuli generated the highest power values at the parietal region, while the novel stimuli were always below baseline. Target stimuli increased induced synchrony in all regions for all participants, but the novel stimulus selectively affected participants dependent on their age and gender. Adult participants, for example, exhibited a reduction in gamma power, but an increase in synchrony to the novel stimulus within the same region. Induced gamma synchrony was more sensitive to the gender of the participant than was induced gamma power. While induced gamma power produced little effects of age, gamma synchrony did have age effects. These results confirm that the perceptual process which regulates gamma power is distinct from that which governs the synchronization for neuronal firing, and both gamma power and synchrony are important factors to be considered for the "binding" hypothesis. However, there is surprisingly little effect of age on the absolute levels of or distribution of EEG gamma in the age range investigated.

Memory Mixed with Desire: A preliminary study of Philosophy and Literature in the works of Friedrich Nietzsche and Milan Kundera Robert Spinelli Brock University, Department of Philosophy This thesis studies intertextuality in the works of Friedrich Nietzsche and Milan Kundera through the primary themes of memory and forgetting. The thesis starts with two introductory chapters that delineate memory according to Nietzsche and Kundera respectively. From here, I move into a discussion of Nietzsche's Ubermensch as an example of the type of forgetting that Nietzsche sees as a cure for the overabundance of memory that has led to Christian morality. Next, I explore the Kunderan concept of kitsch as the polar opposite of what Nietzsche has sought in his philosophy, finishing the chapter by tying the two thinkers together in a Kunderan critique of Nietzsche. The thesis ends with a chapter devoted to the Eternal Return beginning with an exegesis of Nietzsche's idea and ending with a similar exegesis of Kundera's treatment of this thought. What I suggest in this chapter is that the Eternal Return might itself be a form of kitsch even in its attempt to revalue existence.

This study applies a Marxist theoretical paradigm to examine the working conditions of greenhouse workers in the Niagara Region, and the range of factors that bear upon the formation of their class-consciousness. The Niagara greenhouse industry represents one of the most developed horticultural regions in Canada and plays a prominent role in the local economy. The industry generates substantial revenues and employs a significant number of people, yet the greenhouse workers are paid one of the lowest rates in the region. Being classified as agricultural workers, the greenhouse employees are exempted from many provisions of federal and provincial labour regulations. Under the current provincial statutes, agricultural workers in Ontario are denied the right to organize and bargain collectively. Except for a few technical and managerial positions, the greenhouse industry employs mostly low-skilled workers who are subjected to poor working conditions that stem from the employer's attempts to adapt to larger structural imperatives of the capitalist economy. While subjected to these poor working conditions, the greenhouse workers are also affected by objectively alienated social relations and by ruling class ideological domination and hegemony. These two sets of factors arise from the inherent conflict of interests between wage-labour and capital but also militate against the development of class-consciousness. Semi-structured interviews were conducted with 12 greenhouse workers to examine the role played by their material circumstances in the formulation of their social and political views as well as the extent to which they are aware of their class location and class interests. The hegemonic notions of 'common sense' acted as impediments to formation of classconsciousness. The greenhouse workers have virtually no opportunities to access alternative perspectives that would address the issues associated with exploitation in production and offer solutions leading to 'social justice'. Fonnidable challenges confront any organized political body seeking to improve the conditions of the working people.
