The Relationship Between Organizational Culture And The Practice Of Program Evaluation In Human Service Organizations, Lorraine Marais

Dissertations

There are many obstacles for human service organizations in evaluating programs. Some of these barriers are the difficulty in defining human behavior and the change that needs to be evaluated, human service programs that take a long time to show results, agency capacity to do evaluation, and cost (Young, Hollister, Hodgkinson, & Associates, 1993). Another subtle yet powerful influence on the practice of evaluation in nonprofit organizations may be organizational culture (Schein, 1990). If an organization is going to employ self-evaluation, an organizational culture may be needed that will support such efforts. This study was designed to assess the relationship …

A Cross-Sectional Analysis Of The Determinants Of Corporate Share Repurchases, Kenneth M. Washer

Doctoral Dissertations

The objective of this study is to determine which motives play a significant role in determining the extent of a firm's repurchasing activity. For firms repurchasing through the open market, the motives include taking advantage of perceived undervaluation, increasing financial leverage, distributing cash to shareholders, and reducing agency costs. For firms using a tender offer, the motives include taking advantage of perceived undervaluation and having the ability to significantly increase financial leverage. Also, the hypothesis that the perceived undervaluation motive is stronger for smaller firms is tested. Three censored regression models are employed, and each model's explanatory variables represent commonly …

Meta-Ethnographic Development Of A Dialogue Methodology Applied To Organization Discourse, Shelley P. Gallup

Engineering Management & Systems Engineering Theses & Dissertations

A gap exists between theoretical stances that acknowledge the importance of dialogue as a dynamic within socially constructed structures, and "steersmanship" of those constructs--e.g., directing, intervening or transforming organizations. A "mechanism" which links theory with practice is missing, leaving practitioners with an acknowledgment of dialogue's central position, but without tools to enact this centrality in practice or research. This research constructs a conceptual model of dialogue, derived from the literature. Using this model as a base, the research seeks to generate a dialogue methodology bridging theory and practice with respect to organizational dialogue. The model, methodology, and research results are …
