This document is submitted in partial fulfilment for the degree: Masters of Urban Design, Faculty of Engineering and the Built Environment at the University of the Witwatersrand, Johannesburg, 2016 / Six years after the 2010 FIFA World Cup was hosted by South Africa many researchers are still contemplating the so-called positive spin-offs that was propagated (Bond & Cottle, 2012: 1) leading up to this mega-event. Massive capital over-spending, increased public debt and severe under utilisation of these newly constructed iconic stadia and surrounding infrastructure are reported which is representative of the sobering realisation that mega-events, contrary to popular belief, may not be the ‘begin all, end all’ catalyst for urban development – a critique that has been noted in many countries of the north (Haferburg, 2011: 334). Now that the sound of cheering crowds have faded along with visual images honouring the mega-event (Young, 2015), we are faced with the stark realisation that cities need to maintain these expensive facilities and actively seek to attract large events to ensure a relatively stable stream of much required revenue. Santos (2014) questions the amount of rationality applied when such investment decisions are made and points to the generally accepted and portrayed idea that these new iconic stadia will somehow translate into other socio-economic benefits, but argues that due to the rather inflexible use of these facilities, it is very seldom that positive spin-offs are actually realisable. Therefore public investment and expenditure decisions by government have a more significant impact on the inhabitants of an area as they themselves suffer the burden of budgetary deficits, severely increased public debt (Hoiris, 2012), and most importantly, the spatial and resulting socio-economic consequences of ill-advised development. This mammoth of a task (of maintaining facilities) is even further complicated by various degrees of local detachment, socially and functionally, and therefore interventions will need to seek alternative ways to facilitate a sort of ‘re-integration’ into the existing urban fabric by a process of land use redefinition and spatial reconfiguration. Such an issue and approach is no different to the Peter Makoba Stadium in Polokwane and therefore this research will utilise the site as a case study in an attempt to discover whether and how urban design can re-integrate such facilities into cities by developing a new image, use and meaning in order for it to more appropriately fit into the local context. The study firstly explored how and why mega-events has been utilised for urban development globally and what the collective experiences have been. A precedent study was then conducted to determine how other cities have dealt with these challenges and to what extent it has been deemed successful. A process of design approach formulation and interpretation was undertaken that ultimately influenced and informed the proposed urban design interventions for the Peter Makoba Sports Precinct. The proposed urban design interventions is however further aligned to the City of Polokwane’s long term development vision and therefore gives spatial expression to forward planning policies in a more coherent and systematic manner. Finally conclusions are drawn from the study that can serve as a guideline for the future design and development of such facilities. This study therefore explores how a new social and economic meaning can be created and attached to and around the stadium and move towards newer, desirable forms of urbanity that can in return feed back into the city itself. / MT2017

submitted in partial compliance with the requirements for the Master’s Degree in Technology: Chiropractic, Durban University of Technology, Durban, South Africa, 2015. / Background Rugby union is one of South Africa’s most popular sports; it requires high levels of skill and fitness and is played at a high intensity and speed which allows for a greater risk of injury. The high risk of injury is said to be due to the nature of the physicality of rugby. It is because of this high risk of injury that several adaptations of rugby have since developed which rely more on speed and agility than physicality. These adaptations include tens or ten-a-side rugby, sevens or seven-a-side rugby and finally touch rugby, which is played with six players a-side. Each adaptation has its own set of rules and is played differently to the traditional rugby union or fifteen-a-side rugby. Hence, in these adaptations the physicality is said to decrease with a resultant increase in demand for speed and agility. The reduction of physicality and increase in the need for speed and agility would imply that the nature of injuries sustained will be different to those sustained in traditional rugby union. Objectives To develop a profile of injuries that describe the type, anatomical location and mechanism of injuries sustained in tens, sevens and touch rugby; to compare the injuries sustained between the three groups; and, to analyse management strategies utilised by chiropractic students at the 2014 Durban ‘Rugby Rush Tournament’. Additionally this study aimed to provide recommendations to the injury reporting form utilised. Method This study was a retrospective, quantitative, descriptive study based on the Chiropractic Student Sports Association’s report form in order to produce a retrospective cohort analysis of injury and treatment profiles. Participants who made use of the chiropractic treatment facility were required to complete the informed consent section of the injury reporting form. The chiropractic intern was required to complete the remainder of the form pertaining to the participant, complaint and treatment information. This study was limited to event participants to allow for subgroup analysis. The forms were then captured and analysed. Results The data collected consisted of a total of 345 individual patient forms which indicated 626 visits for a total of 733 complaints. The average participant age was 24 ± 5.58. The study found muscle strains (41.5%), SI Syndrome (17.6%) and Joint sprains (15.0%) to be the most frequent diagnoses. A history or previous injury or trauma was reported in 18.7% and 7.40% respectively. Acute injuries accounted for 64.3% and 35.7% were recorded as chronic in nature. The most frequent mechanism of injury was that of overuse (81.9%) and trauma accounted for 17.2% of injuries. The lumbar region (26.1%), thigh (20.7%) and shin/calf (15.6%) were the most commonly reported regions of complaint. Manipulation (58.8%), massage (32.0%) and stretch PNF (27.9%) were the most frequently used treatment protocols. Strapping was utilised in 21.1% of injuries of which 5.20% was applied to the muscle and 13.6% was applied to the joint. No comparison was made using the sevens subgroup as there were insufficient records, thus only tens and touch players were compared. A borderline non-significant difference (p = 0.057) was noted between the type of player and the history of previous trauma. Tens players were more likely to have a history of trauma compared to touch players. A significant difference (p = 0.001) was found between the type of athlete and mechanism of injury. Overuse was more common in touch players whereas trauma was more common in tens players. Due to statistical inconsistencies no significance tests were applicable to compare the type of player and region of complaint. Recommendations were proposed in order to avoid this in future research. Conclusion This study provides a base of knowledge regarding the injuries that were presented to the chiropractic treatment facility at the 2014 Durban ‘Rugby Rush Tournament’ and the management strategies utilised by the chiropractic interns at the event. This research provides insight into injury profiling of tens, sevens and touch rugby players. There were several recommendations proposed for future researchers in order to expand on this field of knowledge.

Diese Dissertation enthält drei Aufsätze zur Theorie der Anreizsetzung bei nicht-verifizierbaren Leistungsmaßen. Untersuchungsgegenstand sind die Auswirkungen individueller Fairnesspräferenzen auf die Ausgestaltung und Eignung verschiedener Anreizmechanismen, welche in realen wirtschaftlichen Situationen Anwendung finden. Alle Arbeiten analysieren Umgebungen moralischen Risikos, in denen eine Firma zwei ungerechtigkeitsaverse Mitarbeiter beschäftigt, deren individuelle Arbeitsleistung zwar beobachtbar, jedoch nicht kontrahierbar ist. Der erste Aufsatz untersucht die Effekte von Ungerechtigkeitsaversion auf relationale Anreizverträge. Als Leistungsmaß eines Agenten dient sein individueller Beitrag zum Firmenwert. Abweichend von der Literatur zeigt sich, dass Ungerechtigkeitsaversion vorteilhaft sein kann: Für bestimmte Zinssätze können relationale Verträge mit neidischen Agenten profitabler sein, wenn sie nicht sogar nur mit solchen implementierbar sind. Der zweite Aufsatz vergleicht relationale Individual- und Gruppenbonusverträge. Durch das Vermeiden ungleicher Löhne sind letztere profitabler, solange sich die Firma keinem Glaubwürdigkeitsproblem gegenübersieht. Dies kann sich jedoch umkehren, da Individualboni vergleichsweise kleiner sind und somit die Selbstdurchsetzung des Vertrags fördern. Ursachen dafür sind das Vermeiden des Trittbrettfahrerproblems und die Anreizwirkung von Neid. Im dritten Aufsatz wird relationalen Individualbonusverträgen ein relatives Leistungsturnier gegenübergestellt. Im Gegensatz zum Bonusvertrag unterliegt das Turnier keiner Glaubwürdigkeitsbeschränkung. Dennoch ist ersteres Anreizschema profitabler, solange das Glaubwürdigkeitsproblem der Firma nicht zu groß ist. Dies liegt an der zwingenden Auszahlung ungleicher Löhne im Turnier und den daraus resultierenden hohen Kosten für Ungleichheitsprämien. Weiter wird für ein Beispiel gezeigt, dass die Zinsspanne, für die der Bonusvertrag das Turnier dominiert, im Neid der Agenten steigt. / This thesis consists of three self-contained essays that investigate the impact of fairness concerns among agents on the design of real-world incentive contracts used to mitigate moral-hazard problems under non-verifiable performance. All papers consider situations in which a firm employs two inequity averse workers whose individual performances are, albeit observable by the contracting parties, not contractible. The first paper studies the effects of inequity aversion on relational employment contracts. Performance is evaluated via an agent’s individual non-verifiable contribution to firm value. In contrast to the literature, we find that inequity aversion may be beneficial: In the presence of envy, for a certain range of interest rates relational contracts may be more profitable. For some interest rates reputational equilibria exist only with envious agents. In the second paper, I compare group to individual performance pay. Avoiding payoff inequity, the group bonus contract is superior as long as the firm faces no credibility problem. The individual bonus contract may, however, become superior due to two reasons: The group bonus scheme is subject to a free-rider problem requiring a higher incentive pay and impeding credibility of the firm. Moreover, with individual bonuses the firm benefits from the incentive-strengthening effect of envy, further softening the credibility constraint. The third paper contrasts a rank-order tournament with independent bonus contracts. Whereas the bonus scheme must be self-enforcing, the tournament is contractible. Yet the former incentive regime outperforms the latter as long as credibility problems are not too severe. This is due the fact that the tournament requires unequal pay across peers with certainty and thus imposes large inequity premium costs on the firm. For a simple example, I show that the more envious the agents are the larger is the range of interest rates for which the bonus scheme dominates the tournament.

Cette thèse se concentre sur trois aspects très différents de l'éducation mais qui affectent chacun la qualité de son offre. Dans le premier chapitre, nous étudions le comportement stratégique adopté à la fois par l'université et par les professeurs, afin pour les uns d'attirer les meilleurs universitaires et pour les autres d'accéder aux meilleures positions, en faisant un compromis entre salaires élevés, sécurité de l'emploi et possibilités de mobilité ascendante. Dans un deuxième chapitre, nous étudions comment la répartition des revenus dans les districts scolaires affecte la qualité des écoles publiques, par la voie des votes locaux et de la fiscalité. En effet, un district scolaire avec une polarisation de revenu plus élevée conduit à un vote pour une faible taxation et donc de plus basses dépenses pour l'école publique impliquant une moins bonne qualité de cette dernière. Enfin, dans un dernier chapitre, nous montrons que les attentes des garçons et des filles concernant leurs futures carrières ainsi que les antécédents scolaires sont façonnés par des stéréotypes de genre. Par exemple, le stéréotype selon lequel les hommes sont meilleurs en mathématiques crée un stéréotype négatif sur les aptitudes des filles en mathématiques. Les stéréotypes représentent l'explication principale dans les différences entre les garçons et les filles en matière de confiance en soi et ont des conséquences importantes sur les chemins qu'ils suivent tout au long de leur vie. / This thesis focuses on three very different aspects of education but which all affect in their way the quality of its provision.In the first chapter, we investigate the strategic behavior adopted by both the university and the professors, in order, for the first to attract the best academics, and for the second to access the best positions making a trade-off between high salaries, job security and upward mobility possibilities. We question the efficiency of such system in attracting, but also in keeping, the best academics. In a second chapter, we investigate how the income distribution of school districts affects the quality of public schools through the channel of local votes and taxation. In fact, an income polarized school district (more poor and rich at the expense of the middle class) leads to a vote for low taxation and thus low expenditure toward public school and a poorest quality of school. The mechanism being that the richest households send their children to private schools and thus are not concerned by public school quality while poorest households can not afford a too high taxation.Finally, in a last chapter we show how boys' and girls' career expectations and educational background are shaped by gender stereotypes. For instance, the stereotype that men are better at mathematics creates a negative stereotype on girls aptitudes in mathematics. Stereotypes represent the main explanation in boys and girls differences in self-confidence, and have important consequences on the paths they take throughout their lives.

Apparus en 1428 en Espagne, le Pas d’armes est un parfait exemple de l’indéniable intérêt porté par la noblesse, de la fin du Moyen Âge et du début de la Renaissance, aux arts martiaux, littéraires et théâtraux. Il s’agit, en réalité, d’une évolution de la joute et du tournoi au cours duquel un ou plusieurs chevaliers est volontaire pour garder un carrefour, une porte ou tout autre lieux symbolique. Pour différencier ces exercices des joutes, les organisateurs publient des chapitres, ou lettres d’armes, plusieurs mois en avance. Ils sont souvent constitués de deux parties, la première venant placer les chevaliers assaillants et défenseurs dans un univers magique et fantastique, le seconde présentant les règles du jeu. Notons également que la majeure partie des Pas plonge les chevaliers dans un monde fictionnel, en particulier inspire de la légende arthurienne, grâce aux chapitres, aux décors et, naturellement, aux costumes. Témoignages des contacts transculturels existent entre les cours d’Anjou et de Bourgogne avec celles d’Espagne, les Pas d’armes sont organisés à des moments décisifs pour les cours, qu’il s’agisse de mariages, de traités de paix ou d’un temps d’après-guerre ; et tous remplissent un rôle commun : mettre en lumière l’unité chevaleresque autour du Prince et de son pouvoir. Invariablement, c’est le Prince qui sort vainqueur des événements qui ont lieux au sein de sa cour. Il s’agit essentiellement pour le prince de mettre en scène son pouvoir dans ce « jeu-mimique » où l’important n’est pas tant le combat que le spectacle et la mise en lumière du pouvoir princier, tant culturel, financier que militaire. / Appearing in 1428 in Spain, the Pas d’Armes are a real example of the undeniable interest held by the nobility of the end of the Middle Ages and the beginning of the Renaissance in the arts of warfare, in literature, and theater. It is in reality an evolution of the joust and tournament in which one or several knights volunteer to keep a crossroad, a door or another symbolic place. To differ from the joust, the organizers publish chapters, or letters of weapons, several months in advance. They consisted of two parts, the first one coming to place the knights defenders and aggressors in a magic and fantastic universe, the second containing rules to be followed. It is also necessary to note that the great majority of Pas place the knights in a fictional world, in particular regarding Arthurian legend, by means of chapters, present scenery around the lists and, naturally, costumes. Testimonies of transcultural contacts between the Valois ‘courts of Anjou and Burgundy and Spanish courts, the Pas d’armes are organized at courtly decisive moments like marriages, treaties of peace or just after a war, all the Pas d’armes had a common role : to highlight the unity of knighthood around the Prince and his power. On each occasion is the Prince who emerges victorious from all the entertainment organized at his court. Essentially, it is a way for the prince to dramatize his power in this “game – mimicry” where the important thing was not so much the fighting but the scenery and the highlighting of cultural, financial and military power of the court.

Indiana University-Purdue University Indianapolis (IUPUI) / In 1964, Muncie Central High School got the “death penalty” at the hands of the Indiana High School Athletic Association’s (IHSAA) new commissioner, Phil N. Eskew, after post-game brawling at a boys basketball game led to a broader investigation of the entire program. In the closing moments of the game, a Muncie Central opponent was bloodied by an inbound pass to the face and fans erupted in violence, swarming the floor. The ensuing investigation revealed racial tensions, issues of sexual mores, political discord, and deep problems in the web of interrelationships that make up the phenomenon of Hoosier Hysteria. After a closed-door hearing and two days of deliberations, Eskew and the IHSAA Board of Control announced their decision, and the punishment prescribed made front page headlines across the state and beyond.
