A literature study was done on the concepts of purchasing and supply management to develop a framework of purchasing and supply management in a mine. A questionnaire was designed, based on the findings in the literature, and to assist to develop a framework of sustainable purchasing and supply management process and procedure towards value creation in a mine. The state of the internal purchasing and supply management process and procedures was assessed through a survey questionnaire to extract the data. The elements of procurement and supply management were broken down into clear activities towards the creation of value in a mine. The key area of concern is to ensure adherence to proper processes and procedures to create an environment that is conducive towards the objectives of the mine and install a mechanism that is measurable. The focus on procurement and supply management towards value creation has became the key determining factor in the mine. A practical development framework of sustainable purchasing and supply management manage towards value is proposed for a mine and to address the gaps found after analysing the questionnaires. The findings of the empirical study and the literature review were used as the basis of the framework. In this thesis the main focus was Purchasing and Supply Management process and procedures, and Contract Management. The relationship between procurement in the supply chain management process and its functional departments is critical towards sustainable development and value creation. Purchasing and Supply Management are one of the key value drivers in a mine and in particular assisting with governance of purchasing activities which contribute significance towards value adding and cost. Finally, conclusions and recommendations are drawn and rendered in order to develop a framework of purchasing and supply management in a mine. / MBA, North-West University, Potchefstroom Campus, 2014

This study proposes a framework for measuring and explaining partnership formation and resilience. The motivation for this study is that we currently do not understand the precise mechanism by which partnerships form or how they stay together in the face of change. The framework draws on a design view of systems to argue that partnerships manage change through boundary spanning practices that operate on multiple levels of social reality. The literature suggests that there are many different types of boundary spanning practices. Some types foster social-technical innovations called "boundary objects" while others facilitate the progressive standardization of those practices through the comparison and selection of boundary objects by social actors who are themselves transformed by their adoption of these objects. The framework proposes a way to measure partnership capacity and social learning that corresponds to the orders of boundary spanning practices. It furthermore proposes three hypotheses, one concerned with partnership formation and two concerned with resilience. The first hypothesis states that partnerships form through a convergence of boundary spanning practices and a community of practice. Convergence depends on a host of factors, including the capacity of innovators and early adopters to leverage their early successes to build additional capital to further promote and eventually institutionalize their boundary spanning practices. The second hypothesis predicts that partnerships that demonstrate a pattern of alignment practices integrating operational and strategic concerns will tend to oscillate within a defined range of partnership functions or "states" (restricted resilience). The third hypothesis predicts that partnerships that inculcate a learning culture of institutional design practices will tend to persist under a theoretically limitless range of environmental demands (general resilience). To assess the framework, four case studies of water resource management partnerships in the Columbia River Basin were carried out. Data collection centered on interviews with boundary spanners, field trips, and secondary data. The results partially confirmed the first hypothesis, while evaluations of the resilience hypotheses were inconclusive. However, boundary spanning practices were catalogued according to the various types of partnership processes to demonstrate how the methodology can be used for cross-case comparisons and theory-building.

This thesis examines the impact of farm level cost efficiency on quota trading in a supply regulated industry. Comparative statics illustrate the role of cost efficiency in quota transfers. For estimation purposes, the dependent variable; net quota purchases is specified both quantitatively and qualitatively and modelled by a linear regression model and multinomial logit model, respectively. Empirical results indicate that variation in cost efficiency does not have a significant effect on the sample producers’ decision to purchase quota. Meanwhile, quota purchasers are younger producers, with large herds, underutilized barn space, and had purchase quota in the previous year. / OMAFRA funding code: 200222

Globalization requires a new understanding of the effect of attitudes in the decision making process, particularly when regional differences arise from different cultural and social norms. Information behavior is the part of behavioral economics that explores decision making stakeholders - consumers, businessmen or politicians, under conditions of bounded rationality. For consumers it is primarily important to buy local products from family farms. The aim of the thesis was to verify the effectiveness of that model in the Czech Republic, especially to fill in the empirical aspect of behavioral economics, relating to consumer behavior under unclear information as well as normal environments, thus understanding the indirect effect of perception on product information. Today these issues are gaining in importance in developed countries as well as in the Czech Republic. The high probability of "never researching product information" resides more within consumers with negative attitudes toward global issues (30%) than in consumers with positive attitudes towards those issues (about 1%). Attitudinal changes affect decreases among those "never searching for product information" (by 30%) as well as increasing "search-rates" (by 60%). In other words, the changes in attitude have significant effects on consumer behavior (Spillover effect). Predicting decision making behavior under unclear information also shows important results. Changes of attitude toward nutrient security, milk of origin or ingredients is associated with relative changes in behavior. A change of attitude will reduce the probability to sometimes buy products with unclear (15%) and increases the probability of buying products with clear information (17%). Empirical research of behaviors under uncertainty are long-term projects, however methodologies may vary differentially. By connecting the theory of planned behavior to the theory of information, these theses fill in the issues of behavioral economics theory. The practical implication is a methodological approach of the model.
