This dissertation examines the relationship among practices and policies of waste/ing and economic structures to make visible the implications of vehicle disposal policies for environmental policy and theory. Consequently, I attempt to build upon the small body of literature that is now critically engaging with waste production and resulting actions/inaction in the form of policies of management. In doing this I use waste as a lens to examine the interrelationships among environmental degradation and economic and political structures. Further, I examine these phenomena in relation to a physical object, the automobile, to add materiality to abstract notions of waste as it relates to both the political and the economic. Through vehicle recycling policies, I analyze how underlying economic structures in contemporary capitalism result in specific responses to the "problems" of waste as well as how the related responses, or "solutions" perpetuate an un-ecological industrial system which severely restricts the possibilities of making substantial change in the production of environmental harms. / Ph.

Organizational researchers focus on group level variables such as organizational climate and organizational structure. The purpose of the current meso-level study is to examine the effects of the structure of an academic department on faculty members' job performance, job satisfaction, and prevalence of counterproductive work behavior (CWB), or harmful behaviors while at work. The sample consisted of 1135 full time faculty members working in 229 academic departments throughout the United States and Canada. Results of the study suggested that faculty members working in a more organically structured department report higher levels of job satisfaction. Additionally, productive faculty members working in more organically structured departments commit fewer instances of abusive behaviors than productive faculty members working in more mechanistically structured departments. The implications as well as limitations of the study are discussed.

One of the major challenges facing South African IT organisations today is the dramatic shortage of IT professionals. Both literature and business sentiment have indicated that employee turnover within the IT sector is on a continually rising trend. The ramifications of these high turnover rates translate into exorbitant direct and indirect costs to organisations. The purpose of this research was to identify the factors pertaining to the underlying structure of the turnover intention of these employees. A deeper understanding of these drivers may possibly enable management to reduce the turnover intention of employees within their organisations. A quantitative, multi-disciplinary research approach, focussing on the antecedents of turnover intention and the three systemic levels of organisational behaviour (micro, meso and macro) was used to operationalise the main research construct of this study. Data was collected by means of an anonymous self-administered web-based survey. A sample of 188 completed questionnaires was collected using a snowball sampling technique from the population of employees in the IT industry in South Africa. A statistical data reduction method, exploratory factor analysis, was conducted on the dataset to determine the underlying nature of the construct, IT employees’ perceived intention to resign from employment. After an appropriate number of factor analytic rounds, a robust 4-factor model of the data set was established. The results indicated that the factor, Personal Enrichment from Management Support, possibly plays the most significant role in understanding, monitoring, and managing IT employees’ perceived intention to resign from employment. The study provided support that monetary factors had the most significant influence in an employee’s decision to join an organisation; however, nonmonetary benefits, such as job satisfaction and skills development, were found to be more effective in retaining employees. The practical implications uncovered from this study will enable management to gain further insight into understanding the underlying factors and drivers of turnover intention and thereby minimise its impact on the organisation. / Dissertation (MBA)--University of Pretoria, 2013. / lmgibs2014 / Gordon Institute of Business Science (GIBS) / MBA / Unrestricted

The general aim of this research is to investigate approaches to: •improve small area market demand (i.e. SAMD) prediction accuracy for the purchase of automobiles at the level of each Census Collection District (i.e. CCD); and •enhance understanding of meso-level marketing phenomena (i.e. geographically aggregated phenomena) relating to SAMD. Given the importance of SAMD prediction, and the limitations posed by current methods, four research questions are addressed: •What are the key challenges in meso-level SAMD prediction? •What variables affect SAMD prediction? •What techniques can be used to improve SAMD prediction? •What is the value of integrating these techniques to improve SAMD prediction? To answer these questions, possible solutions from two broad areas are examined: spatial analysis and data mining. The research is divided into two main studies. In the first study, a seven-step modelling process is developed for SAMD prediction. Several sets of models are analysed to examine the modelling techniques’ effectiveness in improving the accuracy of SAMD prediction. The second study involves two cases to: 1) explore the integration of these techniques and their advantages in SAMD prediction; and 2) gain insights into spatial marketing issues. The case study of Peugeot in the Sydney metropolitan area shows that urbanisation and geo-marketing factors can have a more important role in SAMD prediction than socio-demographic factors. Furthermore, results show that modelling spatial effects is the most important aspect of this prediction exercise. The value of the integration of techniques is in compensating for the weaknesses of conventional techniques, and in providing complementary and supplementary information for meso-level marketing analyses. Substantively, significant spatial variation and continuous patterns are found with the influence of key studied variables. The substantive implications of these findings have a bearing on both academic and managerial understanding. Also, the innovative methods (e.g. the SAMD modelling process and the model cube based technique comparison) developed from this research make significant contributions to marketing research methodology.

L’idée que le football professionnel en Europe est en crise fait très largement consensus parmi les économistes. Dans notre thèse, nous montrons que ce diagnostic suppose de négliger un certain nombre d’éléments constitutifs de l’inscription du football dans le monde économique. C’est pourquoi, nous défendons que, loin d’être en crise, le football professionnel européen est, depuis les années 1980, dans une phase de très forte croissance. Pour ce faire, nous adoptons une démarche mésoéconomique régulationniste et procédons à une analyse systémique et multi-niveaux du football professionnel européen. Nous aboutissons ainsi à la caractérisation d’un « régime économique de fonctionnement » que nous qualifions de « financiarisé » compte tenu de l’instrumentalisation du football par des intérêts financiarisés et de leur influence sur les stratégies des acteurs traditionnels du football. Cette financiarisation du football engendre une forte instabilité de son régime puisque l’activité des clubs implique du déficit et du surendettement. En effet, l’incitation à la performance sportive (ligue ouverte), le fort pouvoir de négociation des joueurs (hold-up) et la souplesse de l’environnement réglementaire du football conduisent les clubs à des niveaux de dépenses élevés. Au contraire des « petits » clubs, cette situation n’est pas problématique pour les « grands » clubs, puisqu’ils sont soutenus par des agents à forte capacité de financement et tirent des revenus élevés de leur participation aux compétitions supranationales. Dans ce contexte, le régime est donc durable : sous l’effet de l’instabilité, les acteurs nouent de nouveaux compromis qui modifient les « dispositifs institutionnels » existants et rendent ainsi pérenne la logique de croissance en vigueur. Il y a donc régulation (au sens de la théorie de la régulation) du football. Il reste toutefois que ces modalités de régulation conduisent à accroître les inégalités entre les clubs et que cela pourrait, à terme, amener à une crise économique majeure du football professionnel européen. / Economists argue that the European professional football is in crisis. This thesis discusses this postulate by testing the relationship between the changes in football and the transformations of modern capitalism. Our methodology is based on a meso-level analysis from the French “Régulation theory” which provides a systemic and multilevel analysis. The thesis thus emphasizes how the progressive integration of financialised interests in football has an influence on the strategies of football traditional stakeholders. It actually shows that the financialisation process of the European professional football leads to growth since the 1980s. However, this growth is rather unstable because losses and indebtedness are part of clubs activity. The incentive for sports performance (open league), the players’ strong bargaining power (hold-up) and the flexibility of the regulatory environment are the main determinants of the clubs’ high spendings. Contrary to the “small” clubs, this situation is not a constraint for the “big” clubs thanks to the financial contributions they obtain from their owners, from their funding partners and from their participation to supranational competitions. In this environment and despite instability, the growth regime remains nevertheless sustainable. The stakeholders create new compromises to reduce imbalances: these compromises are the roots for new institutional arrangements that finally support the growth logic which is in place. There is therefore a “régulation” in European professional football, that is to say a process that contributes to the reproduction of the sector. However, this process paradoxically increases inequalities and may encourage the conditions for a major economic crisis.

The aim of the thesis is to examine contemporary constructions of mixed race in the United States and Britain through the examination of two types of racial projects: the national census and voluntary and community organisations focused on mixed race. Using a combination of critical discourse analysis and qualitative interviews, the research analyses the ways in which mixed race is being described, conceptualised, and constructed through macro- and meso-level racial projects in each nation, in order to compare the racial formation processes that are occurring in the early twenty-first century's "mixed race moment". The thesis builds upon racial formation theory, which argues that the concept of "race" is never fully fixed, but rather is made through socio-historical processes that create, inhabit, transform, and destroy racialised notions over time and context (Omi and Winant 1986, 1994, 2015). The theory examines the struggles over racialised meanings that occur between macro-level and micro-level racial projects. This thesis aims to fill the gap left by this focus through examining racial projects that occupy the socio-political "middle ground" between macro- and micro-level projects: the "meso-level."The research examines the ways in which the state constructs mixed race in the United States and Britain. Each nation's census allowed for mixed race self identification in 2000 and 2001, respectively. The thesis examines the social, historical, and political processes that led to mixed race options at that particular time. It argues that the ways in which the census organisations report upon mixed race functions as a discursive practice that provides an official construction of mixed race through simultaneously reflecting and shaping racialised descriptions and narratives within each nation. The thesis examines the usefulness of "meso-level" projects by exploring the role of mixed race organisations in racial formation processes through the examination of six meso-level mechanisms of racialisation: social identity, social capital, collective action, idioculture, extended networks, and civil society (Fine 2012). Incorporating Michel Foucault's notion of "governmentality" (Gordon 1991), the thesis highlights the ways that mixed race organisations have interacted directly and indirectly with macro-level bodies during and after the addition of the mixed race census options as well as other routes of interaction specific to each national context. The thesis argues that the racialisation that occurs at the macro-level holds a "default" role with which mixed race organisations then engage. This highlights the relative roles of power the institutions have in each national context and the ways they are managed through relations fostered through governmentality. The thesis also examines the discourses used by mixed race organisations in the US and Britain as meso-level racial projects and poses the argument that the varied usage of multiple racialised paradigms leads to an increased relative fluidity in the constructions of mixed race than their respective macro-level projects. The systematic cross-national comparison of the ways mixed race is constructed in the US and Britain highlights the ways in which both macro-level and meso-level organisations articulate and promote racialised ideology through their relative levels of power in society. By analysing and comparing these racial projects and their interactions, the paradigms and discourses used reveal the particularities and overlaps by these organisations as they contest, negotiate, and accept formations of mixed race.

Drawing on the notion of faultlines – a hypothetical dividing line that splits a group into two or more subgroups based on the alignment of one or more individual attributes – this thesis proposes a new approach to the measurement and assessment of board diversity to understand how high(er) performing boards can be built i.e., the multi-dimensional diversity index (MDI). The proposed MDI captures the joint effect of differences in director attributes at four diversity levels for 26,743 directors, namely: (i) surface (or baseline); (ii) identity; (iii) demographic; and (iv) meso-level. The current study uses three-stage least squares (3SLS) with a panel of 3,357 FTSE All-Share index non-financial companies from 2005 to 2018. To this end, a key implication of this study – and by extension, the proposed MDI – is that it challenges the conventional notion that boards are improved ‘enough’ by focusing on the micro-dimension and increasing stand-alone diversity attributes, such as gender. Collectively, this study’s results suggest that a well-diversified board incentivises managers to disclose more information on social and environmental activities in contrast to firms with an extreme faultline score. The results show that highly effective boards with a moderate faultline score at meso-level diversity (e.g., identity, information, and non-demographic attributes) lead to better accounting profitability, corporate value, and market-based performance. Remarkably, the present study finds that nationality diversity per se positively impacts corporate performance; in contrast, the dominance of male directors hinders firm performance significantly.

Resting against a background of local and international movements in respect of human rights, South African educators have had to implement a new curriculum, accept diversity and address inclusive education with little or no training, insight and knowledge. Challenges at all levels in education, impact on the successful education of children and the future of young adults who must as equal members of society enter a fast changing global economy. Challenges for educators in South Africa are unique. The lack of knowledge and training for educators and an inadequate infrastructure of the country present as some of the challenges for educators. This qualitative study deals with the subjective experiences of educators in primary schools. The research indicates that when these challenges are addressed educators will be both, better supported and disposed, towards the implementation of inclusive education idealised as the panacea for social transformation in South Africa. / Educational Studies / M.
