Self-Concept, Schematic Processing and Change in Perceptual-Processing Experiential Therapy
(1994-12) Armstrong, M. Sharon; Toukmanian, Shake
The purpose of the present research was to determine the degree of relationship between pre-treatment to post-treatment changes in clients' self-schemata and level of self-concept, and to explore, both quantitatively and descriptively, the processes involved in the development of self-schemata in the context of the perceptual-processing method of experiential therapy (Toukmanian, 1990). The study was constructed in two parts. Part I focused on the examination of change in self-concept and self-schemata, from the standpoint of clients' in-therapy process and final outcome. As was hypothesized, participants who received perceptual-processing experiential therapy improved on measures of self-concept and self-schemata to a significantly greater degree than participants who received skills training. Correspondingly, clients with the greatest in-therapy gains in perceptual-processing tended to have greater pre-treatment to post-treatment gains on the measures of self-concept and perceptual congruence. These results provided tentative support for the conception of change specified by the perceptual-processing therapeutic approach (Toukmanian, 1992) that self-schemata become more elaborate and flexible as a result of therapy, and that clients who engage in more complex processing operations are more likely to show improvement in self-concept and increased flexibility of self-schemata. In Part II, a descriptive analysis was conducted on one client's experience of a segment of therapy that was identified by her as therapeutically significant, in light of Toukmanian's (1992) model of therapy. The results of this analysis provided support for the proposed model. First, the event that the client described as most meaningful to her was found to be the same segment of therapy that had been described as high processing in terms of Toukmanian's model of perceptual-processing (1992). Secondly, the client was able to identify elements of her in-therapy experience that were conceptually relevant to the taxonomy proposed by the model.

Characterizing therapy focus and exploring client process : investigating therapeutic modalities from a narrative approach
(1996-08) Hardtke, Karen Kristin; Angus, Lynne
The aim of this exploratory study was a systematic investigation of three inter-related areas, a discovery-oriented macro to micro analysis of therapy discourse. The first study goal involved the application of the Narrative Processes Coding System (NPCS; Angus, Hardtke and Levitt, 1992) as a heuristic to explore, rather than to verify, possible differences in the reconstruction and co-construction of the self macro narrative both within therapy dyads exposed to the same treatment modality, as well as across therapeutic approach. Developed within the conceptual framework of the Narrative Processes Theory of Therapy (Angus & Hardtke, 1994), the NPCS is a comprehensive categorization system which first characterizes therapy transcripts according to shifts in topic content and then according to narrative process type. The NPCS also identifies the role of client and therapist in shifting therapy content and narrative process. The NPCS was applied to each therapy session of six good-outcome dyads recently involved in a National Institute Mental Health (NIMH) Study of Depression. Three dyads participated in short-term client-centred therapy while three were exposed to shrot-term process-experiential therapy. The second aim was the identification of the predominant relationship theme in one dyad from each therapy modality represented in this study. Emerging from this second objective, the third and final aim was to explicate this interpersonal theme from the therapy transcripts in order to conduct a comparative analysis of the clients' experience of self, and self in relation to other, by the application of the Client Experiencing Scale (Klein, Mathieu, Gendlin & Kiesler, 1970). Both descriptive and statistical analyses were used. Results from the macro analyses suggested differences in both frequency and pattern of narrative process across therapeutic approach. Differences regarding the role of client and therapist in shifting content and process were also found across approach. Results from applying the Client Experiencing Scale (Klein et. al., 1970) to the explicated interpersonal theme in the two dyads selected for the micro analyses of this study suggested that the process-experiential therapy dyad achieved a higher general level of experiencing of self in relation to order.

A Close Look at the Hydrolytic Mechanism of OXA-58, a Class D β-Lactamase from Acinetobacter baumannii
(2012-04-25) Amini, Kaveh
OXA-58 enzyme from Acinetobacter baumannii is a carbepenm-hydrolyzing class-D β-lactamase which uses a carbamylated lysine to activate the nucleophilic serine used for β-lactam hydrolysis. The deacylating water molecule approaches the acylenzyme intermediate formed between the enzyme and the β-lactam from the α-face. According to our findings, OXA-58 uses the same catalytic machinery observed in class D β-lactamases such as OXA-10. Comparison of active site shape in OXA-58, OXA-24 and OXA-48 with the OXA-10 β-lactamase suggests that these carbapenem-hydrolyzing class D β-lactamases have gained the capability of hydrolyzing imipenem, an important carbapenem in clinical use, by slight structural changes in the active site. Also, investigation of the kinetics of β-lactam hydrolysis by Phen113A, Phen114A, Met225A, Phen113Tyr, Phen114l1e and Met225Thr shows that penicillin G is hydrolyzed better than amoxicillin and ampicillin which are hydrolyzed with comparable catalytic efficiencies. Carbenicillin was the poorest substrate.

Corporate law, pension law and the transformative potential of pension fund investment activism
(2002-07) Kodar, Freya; Condon, Mary
Pension funds, the funds held in trust to support occupational pension plans, represent significant funds of capital. Together with other institutional investors such as mutual funds and hedge funds they have become important actors in financial markets - nationally and internationally. They have significant holdings in national and transnational corporations. They are also deeply implicated in the financial instability of global financial markets, and free market globalization. In the past decade some members of the labour movement have sought to have more active involvement in pension fund investment decision-making. They have seen this involvement as a strategy for influencing corporate management and practice, and for encouraging productivity, local and regional development and long-term growth and sustainability. More radically, they have seen it as a means to create new conceptions of ''value" that include factors other than monetary return, and to transform capital by gaining greater social and democratic control over it. They have pursued strategies such as advocating for greater representation on pension plan boards of trustees or investment advisory committees, shareholder activism including proxy voting, investment screening and economically targeted or community investing. This thesis assesses these strategies within the Canadian context and looks at their transformative potential in light of pension law and corporate law principles and practice. It argues that the current strategies of pension fund activists, even if extended to other types of investors - individuals and institutional - are not likely to lead to more democratic and social systems of corporate regulation. It also suggests that pension fund activists have not fully explored the possibilities created by the fact that pension funds have many ''owners" and "beneficiaries" - legal or otherwise. Nor have their strategies adequately considered the suggestion that the uncertainties of corporate law make completing the separation of the corporation from the shareholder, and creating democratic and social systems of corporate regulation, a more appropriate and meaningful political project. In short, they have not challenged the limitations of pension law and corporate law with strategies that recognize the corporation and markets as social institutions that should be democratically and socially regulated. One avenue for doing this appears to be through utilizing the public pension system, particularly by expanding a funded public pension system, and democratizing the fund investment decision-making process.

The stylistic diversity of the concert saxophone
(York University, 2007-07) Rubinoff, Daniel I.
This thesis examines the sonic parameters and musical versatility of the concert saxophone. Invented in 1840, the instrument failed to become a regular member of the symphony orchestra, and is thus underrepresented in classical music. This researcher argues that the saxophone's unique sonic design makes it an effective contemporary instrument in a wide variety of genres. Specifically, the techniques of subtone, harmonics, and false fingerings are examined from both a performance and compositional perspective. Additionally, the instrument's resemblance to the human voice is documented. An examination of five original saxophone compositions highlights the instrument's flexibility as a solo instrument or as a member of an ensemble. This work adds to the number of original compositions for the saxophone and explores the reasons behind the instrument's success in contemporary music.
