<p> If a successful organization is one where internal strife is minimized, then it stands to reason that a successful leader is an individual who knows how to handle conflict. Handling conflict, though, should not be approached intuitively, as the field of mediation has developed numerous techniques to understand and address conflict. To date, though, these techniques have not been categorized by leadership styles. The purpose of this study was to develop such a framework to understand how conflict resolution relates to the disciplines of mediation, organizational behavior, and organizational leadership. To further this endeavor, four themes were developed. These themes drew upon a quadrant categorization methodology proposed by Leonard L. Riskin, which was then compared to four leadership styles: situational leadership, transformational leadership, leader-member exchange theory, and servant leadership. A phenomenological methodology was used and eight leaders were interviewed to understand how they approach conflict within their respective organizations. Utilizing a story provided by each leader about a conflict each encountered on a frequent basis, the researcher asked a series of randomized questions based on the themes mentioned. By categorizing each leader's response, the study found that a relationship worthy of further research existed between the position of the individual within the organization and how societal norms dictated the methodology the leader used to resolve his/her stated conflict. This relationship supported the use of specific tools developed in mediation that the leader and the organization could embrace to transcend conflict, allowing the organization and hence the leader to be more efficient.</p>

Environmental conflicts are multi-dimensional. Individual components of environmental and resource-related conflicts are closely interlinked with other structural societal elements, including economic, social, political and cultural developments. Coastal areas are significant for people’s subsistence, as well as industrial development, cultural heritage, and waterways; therefore, they require integrated research approaches and the implementation of comprehensive strategies of resource management, dispute resolution and conflict prevention. This qualitative exploratory study contributes to the development of the field of environmental conflict resolution (ECR) by examining the perceptions and experiences of 52 key stakeholders from the coastal areas of the Great Lakes region of Canada and the United States (US) with regards to environmental and resource conflicts and conflict resolution approaches. The study invited coastal stakeholders such as environmental policymakers, researchers, academics, educators and NGO members to share their perceptions, images, experiences and knowledge about environmental and resource conflicts and conflict resolution practices in the coastal areas of the Great Lakes. The framework of this holistic study integrates public policy, alternative dispute resolution, conflict analysis, project evaluation, dialogue and public participation, education and other creative interventions into an inclusive strategy of integrated environmental and resource management of coastal areas. Analysis of the study participants’ responses revealed several key findings. First, the multi-dimensional character of environmental and resource conflicts and the wide range of coastal stakeholders involved necessitate creating spaces for dialogue and communication among coastal stakeholders, which may facilitate relationship building and encourage collaborative problem solving and constructive conflict resolution. Second, establishing links between science and policymaking within environmental and resource management, as well as introducing conflict resolution education for coastal stakeholders, may significantly enhance the capacity of coastal stakeholders in ECR. Third, coastal stakeholders in the Great Lakes have an extensive and wide-ranging existing local knowledge, experience and expertise in resolving environmental and resource conflicts. Fourth, a conflict resolution system’s design developed in this study may serve as an integrated framework for the analysis and resolution of environmental and resource conflicts. This ECR system design involves such important components as conducting conflict and stakeholder analysis; identifying the root causes of conflict; bringing conflict participants together to discuss resolution options; and building in continuous evaluation of environmental conflict resolution processes.

Stereochemistry and chirality are arguably two of the most important subjects pertaining to the development of new pharmaceutical drugs. Since enantiomers have the potential to encompass different pharmacological effects in biological systems, both enantiomers have to be tested for pharmacological activity. Not only has obtaining these single enantiomers become crucial, but formulation of the pure enantiomer of a drug also has the potential to contain advantages for both pharmaceutical formulation and therapeutic effect. Epoxide hydrolase is an enzyme commonly found in nature that catalyses the hydrolysis of epoxides, resulting in the formation of the corresponding vicinal diol. Over the last few years a large amount of research has been completed on these enzymes from sources such as mammals, insects, bacteria and fungi. Micro-organisms especially have enjoyed ample attention because of their abundant supply. Recently it was found that certain yeasts contain this enzyme and have the ability to enantioselectively catalyse certain hydrolysis reactions. Styrene oxides are terminal epoxides that are, due to the reactivity of the epoxide ring, useful synthons in the organic synthesis of pharmaceutical products. The first objective of this project was to synthesize three nitro derivatives of styrene oxide namely para-, meta-, and ortho-nitrostyrene oxide. Al three products were obtained from the corresponding nitrophenacyl bromide in yields of 52%, 90% and 57% respectively. The second objective was lo find a suitable yeast slrain containing the epoxide hydrolase enzyme to enantioselectively hydrolyse the synthesised products and unsubstituted styrene oxide. A screening was completed during which 410 yeast strains from more than 44 genera were tested. Epoxide hydrolase activity was found to be widespread throughout the screened yeast domain, while the genera Candida, Debaryomyces, Pichia, Rhodosporidium, Rhodotorula and Trichosporon specifically were very successful in catalysing the hydrolysis of the substrates. Rhodosporidium toruloides UOFS Y-0471 and Rhodotorula glutinis UOFS Y-0653 were chosen for further studies because of their superior enantioselectivity. The final objective was to optimise these reactions in terms of pH, temperature and substrate concentration. It was found that a pH value of 7.2 and a temperature of 45’C yielded optimal enzyme activity. Increased temperatures (45’C), however, lead to a decrease in enantioselectivity and, in the case of R. toruloides together with the substrate puranitrostyrene oxide, reversed enantioselectivity. Lower temperatures (15’C) increased enantioselectivity, resulting in a remarkable improvement from a 10% yield of the single enantiomer (45’C) to a 35% yield. Surprisingly this temperature decrease had a very small affect upon the reaction time. / Thesis (M.Sc. (Pharmaceutical Chemistry)--Potchefstroom University for Christian Higher Education, 2002.

The objective of this study was to explore the link between school climate and bullying behaviour through a case study of two high schools. Grade 10 students received the two day Cross-Cultural Conflict Resolution (XCCR) Module initiated by YOUCAN. Phase I of this study involved the development of an XCCR Logic Model, which aimed to clarify the objectives and key elements of the XCCR Module. Phase II involved the in depth analysis of the XCCR Module through an 84-item survey and qualitative semi-structured interviews with school and program staff. Data from this study did not indicate any changes in bullying behaviour or school climate between pre-and post-implementation. This study highlights a need to incorporate measures for program adherence and program fidelity in future studies. The results of this study provided two practical contributions, an XCCR Logic Model and information about bullying and school climate for the participating schools.

Using Northern Ireland this study seeks to establish what conditions on the ground must be cultivated in order for this ripe moment to come to pass. This thesis argued that five conditions in particular were necessary, though not necessarily sufficient, for the success of the Belfast Agreement. These five conditions (1) the inclusivity of the negotiation process, (2) efforts to foster positive cross community contact, (3) the positive involvement of external ethno-guarantors(EEGs), (4) the involvement of formal international primary mediators, and (5) the use of targeted economic aid. What emerged was that when taken together, these conditions created the pillars upon which a more stable agreement was reached. What is also important is that none of these conditions are short term investments; they all involved a long term commitment to peacebuilding that began long before the official negotiations of the BA.

ABSTRACT Paths Towards Reconciliation in the Workplace: Exploring the Aboriginal Cultures Awareness Workshop Educational workplace initiatives to address social inequality are widely used within organizations. In the past, these workplace workshops have varied in their underlying philosophical perspectives - with goals ranging from maintaining the status quo to promoting social change. Workshop curriculum grounded in the contact hypothesis have drawn from such diverse fields as social psychology, organizational theory, feminist viewpoints, critical theory, liberatory educational philosophy, conflict resolution and Indigenous approaches. The research to date on the efficacy of these various types of workplace educational programs have been mixed. For the past ten years, the Winnipeg Regional Health Authority has offered the Aboriginal Cultures Awareness Workshop to its health care employees in hopes of addressing the differential medical care received by their Aboriginal patients. This mixed methods research project focused on the perceptions of key stakeholders and workshop participants on the most helpful, and least helpful aspects of the Aboriginal Cultures Awareness Workshop. The findings point towards a conceptual framework on the conditions needed within educational workplace initiatives that can create paths toward reconciliation between different identity groups. Addressing the need for accurate information and developing empathy within an atmosphere of joyful humour that is supported by the circle were the key findings in this research project. Specifically, the findings that informed this conceptual framework included the importance of learning about Aboriginal history from an Aboriginal perspective, the power of storytelling to bridge the divide between different identity groups, how the appropriate use of humour can both ease tension, but also be used to challenge intolerant ideas and finally, the power of sharing circles to create safety and allow for dialogue. Drawing on the contributions of the diverse fields that have historically informed these types of workplace educational programs, this research project integrated the field of peace and conflict studies, and Indigenous perspectives to make a number of recommendations for future workplace educational programs.

The demand for environmental assessments on buildings and energy consumption is increasing as well as the energy performance requirements for buildings. At the same time it is increasingly common with self-producers of heat and electricity generation. The main purpose with this master thesis is to investigate how time resolution affects the environmental assessment of energy consumption in office buildings connected to district heating (DH). Environmental assessments were done with both attributional LCA and consequential LCA with system expansion. Fortum´s DH system in Stockholm was analyzed and district heating production was simulated in a Matlab-model. Greenhouse gas (GHG) emissions for the production were calculated. The heat demand of the office Gångaren 16 in Stockholm was simulated in IDA ICE. Thereafter the environmental impact in terms of GHG emissions was calculated with data from the assessment of the DH production. The results show that the highest time resolution that should be used for environmental assessment of energy consumption in buildings connected to DH is daily average values, regardless of LCA perspective. Moreover, sufficient results are achieved with yearly average values with attributional LCA. The results for consequential LCA with system expansion show that daily and yearly average values are not sufficient. Since peak production is temperature dependent rather than time dependent it is recommended that DH peak production is environmental assessed by temperature in future work.

Despite wide acceptance of the stereotype that women apologize more readily than men, there is little systematic evidence to support this stereotype or its supposed bases. In the present research, I explored whether gender differences in apology behaviour occur and, if so, why they occur. In Study 1, I used daily diaries to assess everyday apologies and found that women indeed apologized more frequently than men did. I found no difference in the proportion of offenses for which men and women apologized, however, suggesting that women may apologize more often than men do because they have a lower threshold for what constitutes offensive behaviour. In Studies 2 and 5, I replicated a gender difference in apology behaviour using hypothetical offenses and obtained evidence that this difference is mediated by different judgments of offense severity. In Study 3, I adapted a signal detection paradigm and demonstrated that women exhibit a more liberal response bias in the direction of remembering an apology. In Study 4, I found that women and men similarly associate apologies with positive outcomes, and that only women endorse the stereotype that women apologize more often than men do. Finally, in Study 6, I conducted a daily diary study with romantic couples and found that, as in Study 1, women and men apologized for a similar proportion of the offenses they reported. Together, these studies suggest that a gender difference in apology frequency is caused by different judgments of severity rather than by a difference in willingness to apologize.

Satellite-based navigation systems make it possible to determine the relative positions of points on the earth with centimetre or even millimetre level accuracy over baselines of up to several thousand kilometres. The highest possible accuracy can only be achieved if the carrier phase integer ambiguities can be resolved. In order to resolve the L1 and L2 integer ambiguities over long GPS baselines, the double difference residual ionospheric errors must be estimated for every satellite, every epoch. The resulting number of parameters is usually too large for estimation using ordinary least squares to be practical due to the time or computing resources needed for the processing. The technique currently used to efficiently estimate the parameters is known as pre-elimination. Pre-elimination divides the unknowns into parameters of interest (the coordinates and ambiguities) and nuisance parameters (the ionospheric path delays). The nuisance parameters are treated as stochastic variables and modelled as process noise, avoiding the need for them to be explicitly estimated. Whilst this approach is highly efficient, it makes assumptions about the stochastic behaviour of the residual ionospheric error that are not necessarily valid. The effectiveness of preelimination can be increased through the use of a deterministic model of the ionosphere. It is the hypothesis of this research that the ionospheric error can be more effectively estimated than is possible with pre-elimination, leading to more reliable ambiguity resolution for long baseline precise positioning.
