Several research projects all over the world have considered transport pricing measures and policies as promising attempts to solve urgent traffic problems in urban areas. One important precondition for the successful implementation of pricing strategies is public acceptability. However, empirical findings have shown that the acceptability of such strategies in general is very low. Aim of this dissertation is to analyse the reasons for the low acceptability of road pricing. The dissertation is organized as follows: Firstly, the problems related to transport and the measures to cope with these problems are outlined. The focus is thereby on economic measures such as road user fees, whose economic and traffic-related assumptions are discussed. Then, a definition of the terms used is given and main European results concerning the current acceptability level of various travel demand management (TDM) strategies are reported. Moreover, a theoretical framework is developed which attempts to identify the essential factors determining transport pricing acceptability. In two empirical studies (N1 = 923, N2 = 667), it is investigated whether and to what extent these factors contribute to the explanation of acceptability. Finally, conclusions are drawn and some recommendations for future research are given. / Straßenbenutzungsgebühren für den privaten Autoverkehr sind vielfach als sinnvoll und wünschenswert vor allem zur Lösung der zahlreichen Verkehrsprobleme in städtischen Ballungsräumen begründet worden. Bisher ist es jedoch nicht zu einer nennenswerten Umsetzung dieser Maßnahmen gekommen. Es herrscht in der Literatur Einigkeit, daß die geringe Akzeptanz von Straßenbenutzungsgebühren in der Bevölkerung und die deutliche Ablehnung bei den betroffenen Autofahrern die wesentlichen Gründe für den fehlenden politischen Willen sind, road pricing einzuführen. Ziel dieser Arbeit war es, die Ursachen und Bedingungen für die mangelnde Akzeptanz von Straßenbenutzungsgebühren bei den betroffenen Autofahrern zu untersuchen. Die Arbeit ist wie folgt aufgebaut: Im ersten Abschnitt wird die Ausgangslage und der Problemhintergrund dargestellt. Es wird erläutert, welche negativen Konsequenzen des motorisierten Individualverkehrs vorliegen, und mit welchen Maßnahmen ihnen begegnet werden kann. Der Fokus liegt dabei auf preispolitischen Maßnahmen wie Straßenbenutzungsgebühren, dessen ökonomische und verkehrswissenschaftliche Annahmen dargestellt werden. Dem gegenübergestellt wird die gesellschaftspolitische Realität: zum einen in Form der massiven Ablehnung von Straßenbenutzungsgebühren durch Bevölkerung und betroffene Autofahrer und zum anderen in Form der zahlreichen, erfolglosen und gescheiterten Versuche, Straßenbenutzungsgebühren einzuführen. Dies mündet in die Ableitung erster Forschungsfragen und in die Entwicklung des Untersuchungsansatzes. Im darauf folgenden Abschnitt werden die theoretischen Grundlagen zur Untersuchung der Akzeptanz von Straßenbenutzungsgebühren gelegt. Dabei wird zunächst geklärt, wie sich der Begriff "Akzeptanz" definieren läßt und in welche relevanten psychologischen Theorien er sich einordnet. Im Anschluß wird das Modell zur Akzeptanz von Schlag vorgestellt und analysiert. Darauf aufbauend werden die zentralen Variablen des Modells auf ihre theoretische und empirische Relevanz und unter Berücksichtigung potentiell konkurrierender Ansätze dargestellt und untersucht. Ziel ist die Klärung der logischen und kausalen Struktur des Modells und der Beziehungen der Variablen untereinander. Dies führt schließlich in die Ableitung überprüfbarer Hypothesen in Form eines erweiterten Akzeptanzmodells. Zur Überprüfung des Modells, der aufgestellten Hypothesen und Forschungsfragen werden zwei Untersuchungen berichtet (N1 = 923, N2 = 667), die inhaltlich aufeinander aufbauen. Diese wurden im Rahmen der EU-Forschungsprojekte TransPrice und AFFORD durchgeführt. Generelles Ziel ist die Validierung der Modellkonstrukte und ihrer angenommenen Beziehungen. Im letzten Abschnitt werden zusammenfassend und basierend auf den beiden Studien die wesentlichen Ergebnisse rekapituliert, sowie offene Forschungsfragen und Anforderungen abgeleitet, die sich zukünftigen Studien stellen. Schließlich wird diskutiert, welche Implikationen sich aus dieser Untersuchung ziehen lassen und welche Aspekte zu berücksichtigen sind, wenn Straßenbenutzungsgebühren der Öffentlichkeit präsentiert werden. - Die Druckexemplare enthalten jeweils eine CD-ROM als Anlagenteil: 490 KB - Nutzung: Referat Informationsvermittlung der SLUB

This Ph.D. thesis in Economics consists of four self-contained chapters that empirically explore sources of economic inequality, using data from experiments, sports competitions, and Swedish registers. Competing biases: Effects of gender and nationality in sports judging explores in-group biases among judges in the equestrian sport dressage – the only Olympic sport with subjective performance evaluations in which male and female athletes compete as equals. International dressage competitions provide a rare opportunity to investigate gender bias and nationalistic bias in the same setting, using naturally occurring data on decisions of professional decision makers. Gender differences in initiation of negotiation: Does the gender of the negotiation counterpart matter? experimentally investigates how gender differences in the willingness to enter a wage negotiation are affected by whether the counterpart is a man or a woman. The importance of family background and neighborhood effects as determinants of crime uses Swedish register data to estimate sibling and neighborhood correlations in criminal convictions and incarceration. Omission effects in fairness behavior experimentally tests if individuals are more prone to act selfishly if they can passively allow for a self-serving outcome to be implemented rather than having to make an active choice. / <p>Diss.

Network Utility Maximization (NUM) provides a key conceptual framework to study reward allocation amongst a collection of users/entities in disciplines as diverse as economics, law and engineering. However when the available resources and/or users' utilities vary over time, reward allocations will tend to vary, which in turn may have a detrimental impact on the users' overall satisfaction or quality of experience. In this thesis, we introduce a generalization of the NUM framework which incorporates the detrimental impact of temporal variability in a user's allocated rewards and explicitly incorporates Mean-Variability-Fairness tradeoffs, i.e., tradeoffs amongst the mean and variability in users' reward allocations, as well as fairness across users. We propose a simple online algorithm to realize these tradeoffs, which, under stationary ergodic assumptions, is shown to be asymptotically optimal, i.e., achieves a long term performance equal to that of an offline algorithm with knowledge of the future variability in the system. This substantially extends work on NUM to an interesting class of relevant problems where users/entities are sensitive to temporal variability in their service or allocated rewards. We extend the theoretical framework and tools developed for realizing Mean-Variability-Fairness tradeoffs to develop a simple online algorithm to solve the problem of optimizing video delivery in networks. The tremendous increase in mobile video traffic projected for the future along with insufficiency of available wireless network capacity makes this one of the most important networking problems today. Specifically, we consider a network supporting video clients streaming stored video, and focus on the problem of jointly optimizing network resource allocation and video clients' video quality adaptation. Our objective is to fairly maximize video clients' video Quality of Experience (QoE) realizing Mean-Variability-Fairness tradeoffs, incorporating client preferences on rebuffering time and the cost of video delivery. We present a simple asymptotically optimal online algorithm NOVA (Network Optimization for Video Adaptation) to solve the problem. Our algorithm uses minimal communication, 'distributes' the tasks of network resource allocation to a centralized network controller, and video clients' video quality adaptation to the respective video clients. Further, the quality adaptation is also optimal for standalone video clients, and is an asynchronous algorithm well suited for use in the Dynamic Adaptive Streaming over HTTP (DASH) framework. We also extend NOVA for use with more general video QoE models, and study NOVA accounting for practical considerations like time varying number of video clients, sharing with other types of traffic, performance under legacy resource allocation policies, videos with variable sized segments etc. / text

Before 1994 administrative law was dominated by parliamentary supremacy which dictated that Parliament is the supreme law-making authority in the state. This position was radically changed by the new democratic order. To protect the rights of citizens a Bill of Rights was introduced in South Africa. This research focuses on the uncertainty pertaining to the application of the audi alteram partem rule to the proceedings of commissions of inquiry. Section 24 of the interim Constitution, section 33 of the final Constitution and the Promotion of Administrative Justice Act 3 of 2000 were introduced to safeguard the individual against unfair administrative action. These legislative measures as well as applicable case law are analysed in order to establish whether they have brought about greater clarity concerning the application of the audi alteram partem rule to the proceedings of commissions of inquiry. / Thesis (LL.M.

La thèse délaisse l’étude des biais, des erreurs et des influences externes qui modulent les décisions de justice et formule l’hypothèse que les individus, confrontés à un dilemme normatif (quelle serait la juste peine?), manifestent un souci de justice qu’il est pertinent d’analyser en lui-même. Les résultats de cette thèse indiquent qu’une proportion appréciable des choix et des jugements des citoyens et des acteurs judiciaires interrogés témoignent, en raison de leur cohérence interne et de leur modération, d’un souci manifeste de justice. Les données de la thèse s’appuient sur un sondage sentenciel dans lequel on demandait à des répondants du public (n=297), mais aussi à un échantillon d’acteurs judiciaires (n=235), de prendre des décisions de détermination pénale dans trois histoires de cas bien détaillées. La thèse s’intéresse à la détermination de la juste peine, laquelle incorpore trois prises de décision distinctes. Le premier chapitre de la thèse s’attarde à la qualité des échelles individuelles de sévérité des peines qui peuvent être infligées pour sanctionner un délinquant reconnu coupable d’actes criminels. Les résultats indiquent que les citoyens, tous comme les acteurs judiciaires, n’utilisent pas la même métrique pour statuer sur la sévérité des peines, mais que certains d’entre eux, font usage d’une métrique pénale plus cohérente et plus raisonnable que d’autres. Un test décisif pour jauger de la valeur d’une métrique est son aptitude à établir des équivalences pénales entre les peines de prison, de probation, de travaux communautaires et d’amendes. Le deuxième chapitre s’attarde à la qualité des choix sentenciels des citoyens et des acteurs judiciaires. Deux critères sont utilisés pour distinguer les sentences les plus justes : 1) le critère de proportionnalité ou de cohérence interne (les sentences données sont-elles toujours proportionnelles à la gravité de l’infraction commise ?); 2) le critère de modération ou de cohérence externe (la sentence donnée peut-elle rallier le plus grand nombre de points de vue?). Les deux critères sont importants parce qu’ils contribuent tous deux à réduire la marge d’incertitude du dilemme sentenciel. Le troisième chapitre prend acte que toute sentence fera possiblement l’objet d’un aménagement subséquent. Les formes les plus manifestes d’aménagement pénal sont régies par l’octroi d’une libération conditionnelle qui écourte la durée de peine qui sera purgée en prison. Certains acteurs judiciaires choisiront de tenir compte de cette libération anticipée en gonflant leur sentence, alors que d’autres se refuseront à le faire. Le dernier chapitre s’attarde aux raisons qui motivent leurs choix. / This thesis neglects the analysis of external influences, such as biases and errors, which may interfere in court judgments and propose that when facing a normative dilemma (What is the just decision?), individuals are driven by a concern for justice. This concern has not been properly scrutinized. When studying legal decisions, we note that a large proportion of all judgments and evaluations made by interviewed citizens and judicial actors are coherent and moderated, which demonstrates a concern for justice and equity. The results of the thesis are based on a sentencing survey conducted among citizens (n=297) and criminal justice professionals (n=235) who had to adjudicate upon three detailed case studies and specific sentencing questions. The thesis examines the process of determining the just sanction and is concerned with three types of judgments. The first chapter explores the quality of different penal severity scales that can be used to punish a criminal convicted of a crime. Results indicate that citizens, as well as criminal justice professionals, have different ways of conceptualizing penal severity, and that some of these views are more coherent and more reasonable than others. This chapter shows that one way of assessing penal metrics quality is to look at the exchange rates among qualitatively different sanctions (months of prison, years of probation, hours of community work and dollar amount of fines). The second chapter examines the sentencing choices. Two important judicial criteria are used to distinguish just sentences from unjust ones: 1) proportionality or internal consistency (are sentences always given in accordance to crime seriousness?); and 2) moderation or external consistency (is the sentence able to merge opposite points of views?). Both criteria are important in reducing a portion of uncertainty that is intrinsic to the sentencing dilemma. Indeed the search for the just punishment and strategies for uncertainty reduction are intimately connected. The third chapter takes into account the fact that sentences are not fully determined at the judicial level. This is especially the case for prison sentences since conditional release mechanisms drastically shorten the time actually spent behind bars. We attempt to understand the differential propensity among judges, crown and defense attorneys and probation officers to anticipate the likely impact of conditional release in determining the presumptive duration of the court sentence. Some court players will incorporate parole outcomes in determining their prison sentence while others refuse to do so. The chapter examines the reasons why they do so and also identifies under what conditions anticipation of parole outcomes are more likely

<p>In an attempt to make South Africa a more just society after the first democratic elections on 27 April 1994, the South African society had to undergo a number of radical changes which impacted the social, economical, political and educational arena. These changes have influenced recruitment, retention and turnover. Changes at leadership levels in the private and public sphere coupled with a huge exodus of highly skilled professionals are evident as topics of equality and social justice appear at the top of company agendas. Many proponents have conducted research on organisational justice and the fact that more than twenty five thousand articles have been published on job satisfaction attest to the importance of these two variables on organisational performance. In an article examining past, present and future states of organisational justice it is argued that organisational justice has the potential to explain many organisational behavioural outcome variables. An investigation of the relationship between organisational justice perceptions and work behavior found job satisfaction to be made up of a large fairness component. The rationale behind the support for the study is the argument that employees who perceive that they have been fairly treated is likely to hold positive attitudes about their work, their work outcomes and their managers. If South African organisations wish to remain competitive then organisations need to understand how perceptions of justice influence attitudes and behaviour and consequently affect the success of the organisation. Agricultural Colleges, a division of the Department of Agriculture are no exception. The Agricultural Colleges' primary aim is to provide training to its prospective communities, and is continuously being evaluated in terms of how well its academic employees achieve its vision, mission and goals. It is evident from responses to job advertisements, low morale and high turnover that most of the academic employees in Agricultural Colleges are dissatisfied with their jobs, pay, management and the institutions based on their current salary. Attracting, recruiting and retraining highly skilled, internationally marketable and mobile employees are critical factors in determining the present and future success in agricultural training in South Africa. Limited research to examine the effects of organisational justice on organisational outcomes in an environment where the workforce consists of academics is the gap this research attempts to fill. This study is designed to assess the impact of organisational justice on job satisfaction of academic employees in agricultural colleges in South Africa. Also, to determine whether biographical values influence the relationship between organisational justice and job satisfaction.</p>

À l’instar de nombreux pays en développement, la prévention et la prise en charge du paludisme présente occupent une place centrale dans les politiques publiques en Côte d’ivoire. En vue de fournir des outils d’aide à la décision aux acteurs politiques, plusieurs études sur l’évaluation de l’efficacité et des coûts des programmes sont régulièrement engagées. Toutefois, très peu d’études se sont penchées sur les dimensions éthiques de ces programmes. En conséquence, nous avons choisi d’explorer dans une perspective éthique les programmes de prévention et de prise en charge du paludisme en Côte d’Ivoire à travers une analyse documentaire descriptive. La méthode qualitative fut retenue à cet effet. Ce mémoire vise à démontrer que la lutte contre le paludisme est une entreprise qui intègre des valeurs éthiques implicites notamment de solidarité et de promotion de la vie en santé. En outre, des mesures particulières notamment de gratuité d’accès aux services de prévention et de prise en charge sont prévues dans le but de prendre en compte les populations vulnérables face au paludisme. Le chapitre d’analyse nous permettra de montrer comment ces dispositions présentent des limites en ce qui concerne l’équité. Enfin, nous allons démontrer que ces dispositions spécifiques sont susceptibles in fine de générer voir d’accentuer les risques d’inégalités sociales. / In the Ivory Coast, like in many developing countries, prevention and management of malaria has occupied a central place in public policy. Many studies evaluating the effectiveness and program costs are regularly conducted to provide tools in order to help improve decision-making for political actors. However, very few studies have examined the ethical dimensions of these programs. I therefore chose to explore the programs of prevention and treatment of malaria in Ivory Coast through an ethical perspective by examining the descriptive literature. The qualitative method was chosen for this purpose. This master’s thesis aims to demonstrate that the fight against malaria implicitly incorporates ethical values such as solidarity and promotion of life through healthcare. In addition, special measures including free access to prevention and care are provided in order to take into account the populations that are particularly vulnerable to malaria. The analysis will show how these measures have limitations in terms of equity. Finally, I demonstrate that these specific measures are generating or even accentuating social inequalities.

Well-being at work is of major public interest, and justice at the workplace can be a key factor contributing to employees and managers feeling well. Research has found direct relationships between organizational justice perceptions and work and health outcomes. With research on the justice–health link still emerging, this thesis examines the moderating and mediating processes for the effects of justice perceptions on work outcomes and especially health outcomes. As little is known about those who enact justice, the antecedents and consequences of justice enactment are also studied. In Study I, the relationships between organizational justice and work and health outcomes were in focus, as the moderating role of job characteristics was investigated utilizing the demand–control(–support) model. Organizational justice and job characteristics were associated with work and health outcomes within and across time. The multiplicative effects showed that the organizational justice effects were stronger when perceived job demands were high, job control was low or social support was low. Study II examined the processes through which justice perceptions translate into health outcomes. Building on the allostatic load model, mental preoccupation with work was found to be a relevant mediator of the justice–health relationship, with locus of control moderating the mediated relationships. Study III focused on the actor perspective. Investigating predictions based on the deontic model of justice and ego-depletion theory, moral regard and justice self-efficacy predicted justice enactment positively, and justice enactment had positive effects on feeling professionally recognized but also negative health consequences for the actors themselves. This thesis contributes to advancing the emergent justice–health research stream by providing insights into the processes underlying these aspects, and by incorporating this stream into the actor perspective. / <p>At the time of the doctoral defense, the following paper was unpublished and had a status as follows: Paper 3: Submitted.</p>

Wireless multi-hop ad hoc and sensor networks provide a promising solution to ensure ubiquitous connectivity for the Future Internet. Good network connectivity requires designing a reliable Medium Access Control (MAC) protocol, which is a challenging task in the ad hoc and sensor environments. The broadcast and shared nature of the wireless channel renders the bandwidth resources limited and expose the transmissions to relatively high collisions and loss rates. The necessity to provide guaranteed Quality of Service (QoS) to the upper layers triggered the design of conflict-free MAC protocols. The TDMA synchronization constraint is basically behind the rush of MAC protocol design based on a fixed frame size. This design shows inflexibility towards network variations and creates a network dimensioning issue that leads to a famine risk in case the network is under-dimensioned, and to a waste of resources, otherwise. Moreover, the alternative dynamic protocols provide more adaptive solutions to network topology variations at the expense of a fair access to the channel. Alongside with the efficient channel usage and the fair medium access, reducing the energy consumption represents another challenge for ad hoc and sensor networks. Solutions like node activity scheduling tend to increase the network lifetime while fulfilling the application requirements in terms of throughput and delay, for instance. Our contributions, named OSTR and S-OSTR, address the shortcomings of the medium access control protocol design in the challenging environment of wireless multi-hop ad hoc and sensor networks, respectively. For OSTR the idea consists in adopting a dynamic TDMA frame size that increases slot-by-slot according to the nodes arrival/departure to/from the network, and aiming to achieve a minimum frame size. For this end, OSTR couples three major attributes: (1) performing slot-by-slot frame size increase, (2) providing a spatial reuse scheme that favors the reuse of the same slot if possible, (3) and ensuring an on-demand frame size increase only according to the node requirements in terms of throughput. To tackle different frame sizes co-existence in the network, OSTR brings a cooperative solution that consists in fixing an appointment, a date when the frame size in the network is increased. Concerning S-OSTR, it is an amendment of OSTR for wireless sensor networks. It brings the idea of a dynamic active period, since it deploys a dynamic frame size that is built slot-by-slot according to nodes arrival to the network. S-OSTR enforces the slot-by-slot frame size increase by a node activity scheduling to prolong the inactivity period in the network, and hence prolong the overall network lifetime for wireless sensor networks. Our contributions are both based on the new dynamic TDMA frame size increase that consists in increasing the frame size slot-by-slot aiming to achieve a shorter frame size, and hence improve the channel utilization, and reduce the energy consumption. The performance analysis of OSTR and S-OSTR shows that they present good potentials to support QoS requirements, to provide energy-efficiency, to ensure fair medium access, to accommodate network topology changes and finally, to enhance robustness against scalability. The impact of this new TDMA frame size increase technique on the medium access control protocol performance is highlighted through multiple simulations of OSTR and S-OSTR. Multiple comparative studies are also handled to point out the effectiveness of this new technique and the soundness of our contributions
