This work is composed of two contributions. One borrows from the work of Charles Kemp and Joshua Tenenbaum, concerning the discovery of structural form: their model is used to study the Business Week Rankings of U.S. Business Schools, and to investigate how other structural forms (structured visualizations) of the same information used to generate the rankings can bring insights into the space of business schools in the U.S., and into rankings in general. The other essay is purely theoretical in nature. It is a study to develop a model of human memory that does not exceed our (human) psychological short-term memory limitations. This study is based on Pentti Kanerva’s Sparse Distributed Memory, in which human memories are registered into a vast (but virtual) memory space, and this registration occurs in massively parallel and distributed fashion, in ideal neurons.
Este trabalho é composto de duas contribuições. Uma se usa do trabalhode Charles Kemp e Joshua Tenenbaum sobre a descoberta da forma estrutural: o seu modelo é usado para estudar os rankings da revista Business Week sobre escolas de administração, e para investigar como outras formas estruturais (visualizações estruturadas) da mesma informação usada para gerar os rankings pode trazer discernimento no espaço de escolas de negócios nos Estados Unidos e em rankings em geral. O outro ensaio é de natureza puramente teórica. Ele é um estudo no desenvolvimento de um modelo de memória que não excede os nossos (humanos) limites de memória de curto-prazo. Este estudo se baseia na Sparse Distributed Memory (Memória Esparsa e Distribuida) de Pentti Kanerva, na qual memórias humanas são registradas em um vasto (mas virtual) espaço, e este registro ocorre de forma maciçamente paralela e distribuida, em neurons ideais.

A presente tese é formada por três trabalhos científicos na área de Management Science Computacional. A gestão moderna e a alta tecnologia interagem em múltiplas e profundas formas. O professor Andre Ng diz aos seus estudantes na Escola de Negócios de Stanford que “Inteligência Artificial é a nova eletricidade”, como sua forma hiperbólica de enfatizar o potencial transformador da tecnologia. O primeiro trabalho é inspirado na possibilidade de que haverá alguma forma de dinheiro digital e estuda ledger distribuídas, propondo e analisando o Hathor, uma arquitetura alternativa para criptomoedas escaláveis. O segundo trabalho pode ser um item crucial no entendimento de tomadas de decisão, nos trazendo um modelo formal de recognition-primed decisions. Situada na intersecção entre psicologia cognitiva, ciência da computação, neuro-ciência e inteligência artifical, ele apresenta um framework open-source, multi-plataforma e altamente paralelo da Sparse Distributed Memory e analisa a dinâmica da memória e algumas aplicações. O terceiro e último trabalho se situa na intersecção entre marketing, difusão de inovação tecnologica e modelagem, extendendo o famoso modelo de Bass para levar em consideração usuário que, após adotar a tecnologia por um tempo, decidiram rejeitá-la.
This thesis presents three specific, self-contained, scientific papers in the Computational Management Science area. Modern management and high technology interact in multiple, profound, ways. Professor Andrew Ng tells students at Stanford’s Graduate School of Business that “AI is the new electricity”, as his hyperbolic way to emphasize the potential transformational power of the technology. The first paper is inspired by the possibility that there will be some form of purely digital money and studies distributed ledgers, proposing and analyzing Hathor, an alternative architecture towards a scalable cryptocurrency. The second paper may be a crucial item in understanding human decision making, perhaps, bringing us a formal model of recognition-primed decision. Lying at the intersection of cognitive psychology, computer science, neuroscience, and artificial intelligence, it presents an open-source, cross-platform, and highly parallel framework of the Sparse Distributed Memory and analyzes the dynamics of the memory with some applications. Last but not least, the third paper lies at the intersection of marketing, diffusion of technological innovation, and modeling, extending the famous Bass model to account for users who, after adopting the innovation for a while, decide to reject it later on.

Abstract:

Complexity of challenges associated with water resources management is increasing due to factors such as climate variability and uncertainty, increased regulatory requirements, changes in planning horizons, and trans-boundary considerations. Integrated Water Resources Management (IWRM) and Adaptive Management (AM) are widely publicized approaches developed and proposed to deal with this complexity. Both concepts have a history reaching back decades, but have been facing difficulties in their transfer from theory into practice. There is a clear need to look in more detail at the process of transforming IWRM and AM theory into practice and this research investigates this process and the factors that mediate it. A conceptual framework was developed - characterizing the process for transfer of theory into practice - that formed the basis for development of the research questions. The research approach focused on analyzing the implementation pathways of IWRM and AM in four case studies, whose selection was informed by the need to explore a context with extensive history of IWRM and AM practice. Data collection took place through semi-structured interviews aiming to uncover how those involved in planning and implementation of IWRM and AM experienced these processes. Besides aiming to understand the ‘lived experiences’, a more abstract framework of the process, factors and dynamics was derived, grounded in the views of the respondents. The findings indicate different types of factors that influence the theory to practice process for IWRM and AM, relating to: (a) theory and its use in practice; (b) the environment that can complicate or facilitate the implementation process; (c) the way cooperation and decision-making processes are organized; and (d) individual attributes of those involved. Incorporating lessons from past into current initiatives are vital to more effective implementation of IWRM and AM. This research gives greater insight into the mediating factors and dynamics, providing this through empirical evidence into design of IWRM and AM planning and implementation. It also provides a thorough discussion on what IWRM and AM exactly mean, proposing a new definition for both concepts.

Abstract:

This thesis explores the use of scientific knowledge in policy-making. It is widely recognised that use of natural resources, such as water, is unsustainable across much of the world. In response, there is a desire for and expectation that science should be used to help improve natural resource management and contribute to the pursuit of sustainability. This research is centred on a comparative case study analysis of the use of science in water resource management policies for Southeast Queensland, Australia. A framework model of the interface between science and policy is developed and applied to the case studies and a range of different uses for science in policy-making are synthesised in the analysis. The relationship between these uses and the need for boundary work to make the science effective is analysed. The findings explore the key factors that influence how science can be used to create effective, efficient and appropriate policies. The research revealed that science can be used in a number of different ways, from simply providing knowledge through to being used in a co-learning process to create a shared understanding. The results show that co-learning is likely to be the most effective use of science, especially when the science is uncertain, but this use requires strong social capital and collaborative governance arrangements. More direct knowledge provision is simpler to implement, but is likely to require shared values and more certain science. In controversial policy issues, where there are conflicting values, science is likely to be used in advocacy and this limits its ability to directly influence outcomes. Hence, the use of science is strongly influenced by the policy context and governance arrangements, but generally strong social capital is likely to support the most effective use of science. This adds further support to calls for stronger social capital and more collaborative governance in sustainability and natural resource management policy.

Abstract:

The international knowledge management field has different ways of investigating, developing, believing, and studying knowledge management. Knowledge management (KM) is distinguished deductively by know-how, and its intangible nature establishes different approaches to KM concepts, practices, and developments. Exploratory research and theoretical principles have formed functional intelligences from 1896 to 2013, leading to a knowledge management knowledge science (KMKS) concept that derived a grounded theory of knowledge activity (KAT). This study addressed the impact of knowledge production problems on KM practice. The purpose of this qualitative meta-analysis study was to fit KM practice within the framework of knowledge science (KS) study. Themed questions and research variables focused on field mechanisms, operative functions, principle theory, and relationships of KMKS. The action research used by American practitioners has not established a formal structure for KS. The meta-data-analysis examined 385 transdisciplinary peer-reviewed articles using social science, service science, and systems science databases, with a selection of interdisciplinary studies that had a practice-research-theory framework. Key attributes utilizing Boolean limiters, words, phrases and publication dates, along with triangulation, language analysis and coding through analytic software identified commonalities of the data under study. Findings reflect that KM has not become a theoretically saturated field. KS as the forensic science of KM creates a paradigm shift, causes social change that averts rapid shifts in management direction and uncertainty, and connects KM philosophy and science of knowledge. These findings have social change implications by informing the work of managers and academics to generate a methodical applied science.

Abstract:

Forest health in the United States has been suffering due to threats such as climate change, wildfire, and human development. As a result, efforts are being undertaken to restore natural processes, improve health, and foster resilience in forested systems. Such efforts involve diverse stakeholders, land management agencies, scientists, and the public, who work together collaboratively to find common goals and agreeable solutions. Central to collaborative forest management is an emphasis on using science to inform decision-making. Yet there are many challenges to applying science in decision-making and developing actionable scientific information for management. Many of the efforts to better align science and decision-making have focused on climate research, and additional empirical evidence is needed to provide context-specific recommendations for connecting science and decision-making in different areas of natural resource management. To that end, this dissertation provides an assessment of the role of science in collaborative forest management. The central question that unifies this work is: how is science applied in decision-making for collaborative forest management, and in what ways can the use of science for decision-making in this context be improved? The first two appendices address this within the context of the Collaborative Forest Landscape Restoration Program (CFLRP): Appendix A examines the role of science in the CFLRP; and Appendix B assesses how science informs decision-making in the CFLRP. Appendix C addresses the application, development, and communication of scientific information to support resilient forest management. This dissertation illustrates the importance of common goals, in-person interactions, and sustained communication between scientists and decision-makers in order to integrate science into the forest management process.

Abstract:

Fishery resources are in principle renewable, but modern fisheries are typically characterised by excessive fishing effort, fleet overcapacity, illegal, unregulated and unreported (IUU) fishing along with deficient governance. This has led to growing trends of unsustainability. Fisheries management is a social and political process which aims to regulate human activities within the constraints of the biological ecosystem in which it operates. But the incorporation of sustainability into fishery practices around the world has to date generally failed. In this thesis I explore the relationship between science and politics in several different spheres of marine resource management. Analysis of the extent to which European politicians have adhered to scientific recommendations on annual total allowable catches (TACs) from 1987 to 2011 for 11 stocks revealed that in 68% of decisions TACs were set higher than recommendations. Politically-adjusted TACs averaged 33-37% above scientifically advised levels. A simple stochastic model indicated that such politically-driven decision-making dramatically reduces stock sustainability. With 88% of European fish stocks overexploited relative to maximum sustainable yield targets, I conclude that political mismanagement must bear a considerable share of the responsibility for this decline. Whilst the practice of political adjustment of scientific advice reveals the negative political impact on management and its failure to integrate science into management, the establishment of marine protected areas (MPAs) shows the relationship between science and politics in a more positive light. MPAs are increasingly being established to protect and rebuild coastal and marine ecosystems. However, the process of establishing these areas is not simple, particularly in areas beyond national jurisdiction (ABNJ) where few MPAs currently exist. Nevertheless, in 2010 the OSPAR Commission successfully established six MPAs forming the world's first network of MPAs in ABNJ. I summarise how this network was created, identify the main challenges, and offer a series of key lessons learned, highlighting approaches that may also be effective for similar efforts in the future. This success story was driven by strong political commitment and based on the best available science, and serves as an example of the positive integration of science into management by politicians. The difficult relationship between science and politics is illustrated clearly by the story of the Atlantic bluefin tuna (Thunnus thynnus). This species has become the quintessential example of overfishing and general mismanagement of the world’s fisheries. An age-structured spatial model of the two stocks of Atlantic bluefin tuna highlighted the importance of taking area and stock movement into consideration when determining total allowable catches for the Atlantic bluefin tuna fisheries. The western bluefin stock was found to be more sensitive to assumptions of stock movement and mixing than the eastern populations, corroborating previous research. My results also indicated that to maximise the total catches of bluefin in perpetuity, it may be better to cease fishing in the western Atlantic and to only target individuals in the eastern Atlantic. The estimated timeframes for recovery are found to be medium to long term if fishing were halted today (within 20 years for both stocks to attain their BMSY) and it is estimated that a 34% reduction in fishing mortality on both stocks is the minimum required decrease to ensure recovery. The aim of this model is to further research on the integration of science into a political management system in order to create a sustainable fishery. In this thesis I identify several important requirements for sustainable fisheries management, namely: the need for a sound scientific basis, stakeholder engagement and cooperation, and strong political commitment and willingness.

Abstract:

The spread of Information and Communication Technologies (ICTs) has transformed the way we deliver services, and has made them in general more efficient and more accessible to users. With these improvements however came new challenges. The extensive use of electronic services in our daily life, and the massive gathering of transactional data have led to serious privacy violations.
In this thesis we provide techniques to enhance users' privacy, and to give them greater control over their data. We propose a protocol allowing users to authorize access to their remotely-stored records, according to a self-chosen privacy policy, and without the storage server learning the access pattern to their records, or the index of the queried records. This prevents the storage server from linking the identity of the party retrieving a record to that of the record owner. In many applications, the association between the identity of the record retriever and that of the record owner represents sensitive information, and needs to be kept private. The proposed protocol is called Accredited Symmetrically Private Information Retrieval (ASPIR), and uses Brands's Anonymous Credentials [Bra00] and a Symmetrically Private Information Retrieval (SPIR) scheme by Lipmaa [Lip05], as building blocks.
Next, we extend the above ASPIR protocol to a setting where the stored records belong to multiple owners simultaneously. The new protocol, called Multi-Authorizer ASPIR, allows the owners of a record to authorize access to their data according to a self-chosen privacy policy, without the storage server learning the access pattern to their record. We present constructions for settings where the retrieving party has to provide authorizations either from all the owners of the target record, or from a subset of them of size greater that a certain threshold. We also consider the case of a General Access Structure, where the retrieval is allowed only if authorizations from certain pre-defined subsets of the owners are provided. The Multi-authorizer ASPIR protocol is more efficient than ASPIR, and can be built with any SPIR primitive.
Finally, we dedicate the last part of the thesis to applying privacy preserving techniques to a real world problem. In particular, we consider the area of e-health, and provide a privacy-preserving protocol for handling prescriptions in the Belgian healthcare system.
La prolifération des services électroniques a eu des retombées positives sur nos sociétés. Les technologies de l'information ont révolutionné divers domaines clé de notre vie, notamment les services gouvernementaux, les affaires, la santé, les transports, les communications et l'éducation. Souvent, le passage au numérique, a rendu les services plus accessibles, plus rapides, plus faciles à utiliser et socialement plus inclusifs. Cependant, avec ces améliorations sont apparus aussi de nouveaux problèmes. En effet, l'utilisation des services électroniques au quotidien, et la collecte massives de données transactionnelles sur les utilisateurs, ont conduit à l'établissement de ce qu'on appelle communément les "dossiers électroniques". Un dossier électronique est une compilation de données personnelles récoltées lorsqu'un individu effectue des transactions électroniques ou reçoit des services. Ces dossiers sont de plus en plus utilisés par le gouvernement et les corporations pour prendre des décisions importantes sur les individus, sans que ces derniers ne soient capables d'y participer.
Cette thèse présente des techniques pour protéger davantage la vie privée des citoyens et leur donner plus de contrôle sur leurs données. On propose, entre autres, un protocole pour permettre à des utilisateurs d'autoriser l'accès à leurs données, sauvegardées sur un serveur distant, sans que celui-ci n'apprenne d'informations sur la fréquence et la distribution des accès, ou même sur l'indice des données récupérées. Ceci empêche le serveur d'établir des liens entre l'identité d'un propriétaire de données, et celle de l'agent qui a demandé l'accès à ses données. On peut penser à une multitude de scénarios où la divulgation de l'existence d'un tel lien est non souhaitable. Le protocole qu'on propose est nommé ASPIR de l'Anglais (Accredited Symmetrically Private Information Retrieval), et utilise les systèmes de certification de Brands [Bra00], ainsi que le système SPIR de Lipmaa [Lip05].
Dans un deuxième temps, on généralise le protocole ASPIR initial à un environnement où les entrées appartiennent à plusieurs parties. Le nouveau protocole, nommé Multi-Authorizer ASPIR, permet aux propriétaires d'autoriser l'accès à leurs données selon une politique qu'ils ont eux même choisie, et sans que le serveur n'apprenne des informations sur la fréquence et la distribution des accès. On présente des constructions pour des scénarios où le demandeur de données doit fournir une autorisation de la part de tous les (respectivement une partie des) propriétaires. Le protocole, Multi-authorizer ASPIR, est plus performant, et peut être implanté avec n'importe quel système SPIR.
Enfin, la dernière partie de la thèse est dédiée à l'application des techniques de protection de la vie privée à un exemple concret de la vie courante. L'exemple qu'on traite appartient au domaine de la santé. On présente alors un protocole pour gérer les ordonnances médicales, qui est compatible avec le système de santé Belge. Le protocole proposé préserve la vie privée des patients et des médecins.

Abstract:

The popularity of massively multiplayer games has increased in recent years and game providers are facing scalability problems to accomodate growing populations of users. Broadcasting all state changes to every player is not a viable solution to maintain a consistent game state in a massively multiplayer game. To successfully overcome the challenge of scale, massively multiplayer games have to employ sophisticated interest management techniques that only send relevant state changes to each player. In this thesis we develop a space partitioning technique based on triangulation that adapts to the world’s obstacles. We introduce obstacle-aware interest management algorithms that use the triangular partitioning to determine the relevance of objects based on the occlusion created by obstacles. We compare the performance of both obstacle-aware and state-of-the-art interest management algorithms based on measurements obtained in a real massively multiplayer game using human and computer-generated player actions. We show that obstacle-aware interest management algorithms can reduce the number of update messages between players and that algorithms based on our triangle-based partitioning can scale to a larger number of objects. The experiments also show that measurements obtained with computer-controlled players performing random actions can approximate measurements of games played by real humans, provided that the traces of the random players are designed adequately. As the size of the world and the number of players of massively multiplayer games increases, adaptive interest management techniques such as the ones studied in this thesis will become increasingly important.
La popularité des jeux massivement multijoueurs a augmenté de façon phénoménale au cours des dernières années. Les fournisseurs de jeux rencontrent de plus en plus de problèmes d’extensibilité pour supporter des populations croissantes de joueurs. La diffusion à tous les joueurs des changements réalisés dans le monde virtuel n’est pas une solution viable pour maintenir une vision cohérente du monde dans un jeu massivement multijoueurs. Pour surmonter ce défi d’extensibilité, les jeux massivement multijoueurs doivent utiliser des techniques de gestion d’intérêt sophistiquées qui relaient seulement l’information pertinente vers chaque joueur. Dans cette thèse nous développons une technique de partition de l’espace qui s’adapte aux obstacles du monde virtuel en utilisant une triangulation. Nous présentons des algorithmes sensible-aux-obstacles de gestion d’intérêt qui emploient les partitions triangulaires pour déterminer la pertinence des objets pour chaque joueur, selon l’occlusion créée par les obstacles. Nous comparons l’efficacité des algorithmes sensible-aux-obstacles et d’autres algorithmes modernes de gestion d’intérêt à l’aide de données obtenues d’un vrai jeu massivement multijoueurs. À cet effet, nous utilisons à la fois des actions de vrais joueurs et des actions de joueurs générées par ordinateur. Nous démontrons que les algorithmes sensible-aux-obstacles de gestion d’intérêt peuvent réduirent le nombre de messages relayés entre les joueurs. Nous démontrons également que les algorithmes utilisant notre partition triangulaire peuvent s’adapter à un plus grand nombre d’objets tout en conservant de bonnes performances. Nos expériences suggèrent également que les résultats obtenus à partir de joueurs contrôlés par ordinateur se déplaçant aléatoirement ce rapprochent des résultats obtenus avec de vrais joueurs, dans la mesure où les actions aléatoires des joueurs son

Abstract:

Abstract The virtual organisation challenges traditional management assumptions because a new means of coordinating globally dispersed employees is needed. To understand the collective activities of a workforce separated by space and time, this paper describes a complexity science-based management framework for virtual organisations. Specific focus is on a South African virtual organisation as a complex adaptive system. A single, embedded case study strategy was followed, and multiple data sources used to generate theory. In this paper, results are reported that clarify the management of an organisation where technology replaces conventional face-toface contexts for socialisation and assimilation. The paper shows how managers create a virtual context for sharing meaning and interaction through synergy, empowerment, participation and an accountable, committed workforce.

Abstract:

One of the biggest challenges in contemporary global environmental governance is the future of marine biodiversity. Over the years, increased fishing efforts in previously remote areas drove many fish stocks to scarcity. The Regional Fisheries Management Organizations (RFMOs) emerged to solve the international fishery crisis, on the assumption that they would provide a forum where Member States may agree and discuss binding rules for the conservation and management of fish stocks within its geographical area of responsibility. Although some agreements existed for more than 60 years, many authors agree that they have not been fully effective in promoting the maintenance and conservation of fish stocks. There are many reasons that might explain the lack of effectiveness, one of them being that science is not very often listened to in the political decision-making process. In this research, the influence of knowledge and science in shaping policy decisions will be observed and analyzed. Therefore, the use of the epistemic communities theory, that which forms part of the constructivist turn in international relations -- was used to answer the main question posed here: when does power listen to science? When it does, does it bring more effectiveness in terms of knowledge, input from epistemic communities, does it induce states to change their behavior, and do these influences lead to policies, which can credibly improve biomass? Using process tracing, through elite interviews, and with a systematic compilation and study of meeting reports from three RFMOs: the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR); the International Convention for the Conservation of Atlantic Tunas (ICCAT); and the Commission for the Conservation of Southern Bluefin Tuna (CCSBT), the final conclusion is that they may listen to science, but their strategy, allies, and the ways in which it occurs differ case-by-case.
Um dos maiores desafios na governança ambiental global contemporânea é o futuro dos ecossistemas e da biodiversidade marinha. Ao longo dos anos, o aumento do esforço de pesca nas áreas anteriormente remotas levou muitas populações de peixes à escassez. As Organizações Regionais para o Ordenamento Pesqueiro (OROPs) surgiram para resolver a crise internacional de pesca, através um fórum onde os Estados-Membros podem acordar e discutir regras vinculativas para a conservação e gestão dos recursos pesqueiros no âmbito da sua área geográfica de responsabilidade. Embora alguns acordos existam há mais de 60 anos, muitos pesquisadores concordam que os mesmos não têm sido totalmente eficazes para promover a manutenção e conservação dos recursos pesqueiros. Muitas razões podem explicar a falta de eficiência no manejo, uma delas é que, o aconselhamento cientifico não é muitas vezes considerado nas decisões políticas. Nesta pesquisa, a influência do conhecimento e da ciência na tomada de decisões políticas serão avaliadas. Para isso, a teoria das comunidades epistêmicas, que faz parte da veia construtivista em Relações Internacionais, foi usada para responder à principal questão colocada aqui: quando é que o poder ouviu a ciência? E isso trouxe mais eficiência em termos do conhecimento proveniente das comunidades epistêmicas induzir os Estados a mudarem seu comportamento e a influência levar a políticas que aumentem a biomassa dos estoques pesqueiros? Com o uso de process tracing, por meio de entrevistas com atores e uma compilação sistemática dos relatórios das reuniões anuais, as OROPS: CCAMLR, ICCAT e CCSBT foram estudadas, e a conclusão final é que, os tomadores de decisão podem ouvir a ciência, porém, a estratégia, os aliados e a forma como a influência se desenvolve varia caso a caso.

Abstract:

The dominant role of social networking in the web is turning human relations into conduits of information flow. This means that the way information spreads on the web is determined to a large extent by human decisions. Consequently, information security, confidentiality and integrity of shared data, relies on the quality of the collective decisions made by the users. Recently, many access control schemes have been proposed to control unauthorized propagation and modification of information in online systems; however, there is still a need for mechanisms to evaluate the risk of information leakage and unauthorized modifications within online systems. First, the thesis focuses on the confidentiality of information in online social networks. A novel community-centric confidentiality control mechanism for information flow management on the social web is presented. A Monte Carlo based algorithm is developed to determine the potential spread of a shared data object and to inform the user of the risk of information leakage associated with different sharing decisions she can make in a social network. The scheme also provides a facility to reduce information flowing to a specific user (i.e., black listing a specific user). Second the thesis focuses on the integrity of artifacts in crowdsourcing systems. A new approach for managing the integrity of contents created in crowdsourcing repositories named Social Integrity Management (SIM) is presented. SIM integrates two conflicting approaches to manage integrity in crowdsourcing systems: owner-centric and owner-free schemes. The ownership bottleneck is relaxed by including co-ownerships and having multiple versions. Finally, the thesis presents a thorough analysis of the Stack Exchange sites as an example of widely used crowdsourcing question answering systems. The dump datasets are used to analyze various user behaviors in crowdsourcing question answering systems by considering the effect of tagging, user reputation and user feedback. Observed characteristics from the studies are used in the modeling and evaluation of social integrity management.
Le rôle prépondérant des réseaux sociaux sur le web change les relations humaines enconduits d'échange d'information. Ainsi, l'information qui est véhiculée sur le web est déterminée en grande partie par les prises de décisions humaines. Conséquemment, la sécurité de l'information, la confidentialité et l'intégrité de l'information partagée dépendentde la qualité des décisions prises collectivement par les utilisateurs. Récemment, plusieurs schémas de contrôle d'accès ont été proposés pour contrôler la propagation non autorisée et la modification de l'information dans les systèmes en ligne. Par contre, il y a encore un besoin de mécanismes dévaluation des risques de fuites d'information et de modifications non autorisées à l'intérieur des systèmes en ligne. Premièrement, la thèse se concentre sur la confidentialité de l'information dans les réseaux sociaux en ligne. Un nouveau mécanisme de contrôle de la confidentialité axé sur la communité pour la gestion de circulation de l'information est présenté. Un algorithme basé sur le modèle Monte Carlo est développé pour déterminer la possibilité de la diffusion des éléments de données partagés ainsi que pour informer l'utilisateur des risques de fuite d'information associés aux différentes décisions de partage que l'utilisateur pourra faire dans un réseau social. Le schéma fournit également une installation pour réduire l'échappement de l'information à un utilisateur spécifique (ex. mettre un utilisateur sur une liste noire). Deuxièmement, la thèse se concentre sur l'intégrité des objets des systèmes de crowdsourcing. Une approche nouvelle pour gérer l'intégrité du contenu créé par les archives de crowdsourcing appelé Gestion de l'intégrité sociale (Social Integrity Management) est présentée. Cette approcheintgre deux approches contradictoires pour gérer l'intégrité des systèmes de crowdsourcing: les schémas basés sur le propriétaire et les schémas sans propriétaires. La problématique de la propriété est d´etendue en incluant la copropriété et la possibilité d'avoir plusieurs versions. Finalement, la thèse présente une analyse complète des sites d'échange commeexemple de système de réponses aux questions par le crowdsourcing qui sont grandement utilisés. L'ensemble de données déchargées est utilisé pour analyser le comportement de différents utilisateurs dans les systèmes de réponses aux questions basés sur le crowdsourcing en considérant les effets d'étiquetage, la réputation des utilisateurs et les commentaires des utilisateurs. Les caract´eristiques observées par les études sont utilisées dans la simulationet l'évaluation de la gérance de l'intégrité sociale.

ENGLISH ABSTRACT: Multiprotocol Label Switching (MPLS) is a routing technology which can manage Quality of Service (QoS) in scalable connectionless networks using relatively simple packet forwarding mechanisms. This thesis considers the optimisation of the QoS offered by an MPLS network. The QoS measure used is the expected packet delay which is minimised by switching packets along optimal label switched paths (LSPs). Two mathematical models of MPLS networks are presented together with appropriate algorithms for optimally dividing the network traffic into forwarding equivalence classes (FECs), finding optimal LSPs which minimise the expected packet delay and switching these FECs along the optimal LSPs. These algorithms are applied to compute optimal LSPs for several test networks. The mathematics on which these algorithms are based is also reviewed. This thesis provides the MPLS network operator with efficient packet routing algorithms for optimising the network's QoS.
AFRIKAANSE OPSOMMING: Multiprotocol Label Switching (MPLS) is 'n roeteringsmetode om die diensvlak (QoS) van 'n skaleerbare, verbindinglose netwerk te bestuur deur middel van relatief eenvoudige versendingsmeganismes. Hierdie tesis beskou die optimering van die QoS van 'n MPLS-netwerk. Die QoS-maatstaf is die verwagte vert raging van 'n netwerk-pakkie. Dit word geminimeer deur pakkies langs optimale "label switched paths" (LSPs) te stuur. Twee wiskundige modelle van MPLS-netwerke word ondersoek. Toepaslike algoritmes word verskaf vir die optimale verdeling van die netwerkverkeer in "forwarding equivalence classes" (FECs), die soektog na optimale LSPs (wat die verwagte pakkie-vertraging minimeer) en die stuur van die FECs langs die optimale LSPs. Hierdie algoritmes word ingespan om optimale LSPs vir verskeie toetsnetwerke op te stel. Die wiskundige teorie waarop hierdie algoritmes gegrond is, word ook hersien. Hierdie tesis verskaf doeltreffende roeteringsalgoritmes waarmee 'n MPLS-netwerkbestuurderj-es die netwerk se QoS kan optimeer.

Abstract:

The purpose of this project is to study and analyze the Server Management System (SMS) which is a significant and dominating factor in most modern networks and servers that are developed today. Modern day servers and the optimized utilities they offer may have major drawbacks, which can lead to network failure if left unmanaged. They require essential aspects like managing and monitoring. Apart from being able to fullfil high end services, maintenance is still a key. SMS is significant because modern day networks require constant supervision and monitoring. It can be very crucial to a small business or enterprise environment to monitor their servers on a regular basis ensuring that this communication loss does not occur. SMS monitor application servers alert a user for failing components and notify the respective administrator. Monitoring specification for user’s application servers are provided by the user. SMS pings the user’s server and also provides an interface for the user to check the status of servers, irrespective of whether they are active or not. While updating the status of individual application servers, if the SMS sees that the status is inactive, a component of the system will try to restart the server and generate another component to analyze and notify the user about the cause for the failure of the individual application server via mail or messages. In this case, SMS helps the user to monitor their application server and save communication loss by rebooting application servers. Available tools for monitoring application servers cannot be customized according to user requirement. For example, they are not able to check server the status every second, cannot reboot the server, and cannot optimize resources on the server. The SMS uses Event Based Architecture (EBA) which makes it optimized. Implementation of EBA provides customization in SMS. The SMS involves many components that constantly monitor the system. Each component plays a major role in the SMS architecture and provides a real-time monitoring solution for application servers.

Abstract:

This doctoral project is an inter-disciplinary study that brings together theology and management science. Its goal is to synthesize, through an appropriate theological method, a framework to reorientate management theories so as to render them more suitable for management in the Roman Catholic Church, as well as more conducive for human flourishing in all organizations. It is hoped that this project will contribute towards the theological scholarship that is much needed amidst an increasing influence of the managerial culture in both Church and society. Chapter 1 begins with a survey of pastoral management literature in the Catholic Church, noting the ways in which theories from management science have been applied. The survey reveals that much of the pastoral materials adopt business management ideas in a direct and uncritical manner, leading to conflicts with the Church’s values, ecclesiology, and worldview. A key issue highlighted in this thesis is the need for proper methodology in inter-disciplinary work. Based on current debates regarding theological and pastoral engagement with the social sciences, Chapter 1 argues that management theories need to be reoriented with the aid of theology before they can be fruitfully applied in church management. It proposes that a reorientation framework can be synthesized for this purpose, and that the synthesis can aim more broadly at a framework which would reorientate management theories to better promote human flourishing in all types of organizations, without compromising its suitability for church management. In this way, the internal challenge of management in the Church can be turned into an opportunity to collaborate with others towards improving management in society as a whole. Chapter 2 proceeds with the framework’s synthesis by conducting a critical examination of the management field. It analyzes the historical development of the field as well as its current internal debates. The analysis reveals that the main problems in the field include its lack of normative values, its reductionist assumptions about the human person, the organization, and society, its over-optimism about technique, its top-down nature, and its current fragmentation and lack of integration. Although alternative principles for management have been proposed by scholars within the field, Chapter 2 points out that these alternatives lack an adequate account of the human person and society, human flourishing, epistemology, and the religious horizon. The chapter proposes that these gaps can be fruitfully addressed through dialogue with a faith tradition. To this end, Chapter 3 examines the Second Vatican Council’s Pastoral Constitution on the Church and the World Today, Gaudium et Spes (hereafter GS), to draw insights and principles for management. After outlining the document’s suitability for this project and 9 establishing principles for its interpretation, the chapter discusses GS’s teachings on the human person and society, the nature and purpose of human work, and the Church’s vision of human finality. It also examines GS’s view of truth and human knowledge, and draws implications for management theories. The analysis reveals that GS’s teachings have much to contribute to management science. Nevertheless, like the management field, the document is also not without internal conflicts, nor does it provide a full account of management. Hence, a central argument of this thesis is that resources from the secular sciences and the faith tradition do not function directly as foundations but as data, in the dialogue between both sides. The resolution of this dialogue requires a higher viewpoint that would provide the foundational criteria with which to evaluate resonances and conflicts emerging from the dialogue. Chapter 4 establishes that this higher viewpoint can be found in intellectual, moral, and religious conversions as expounded by Bernard Lonergan. The chapter points out the suitability of these conversions for management science, and their ability to provide objective and normative foundations for management. It highlights that the implications of intellectual, moral, and religious conversions include adoption of a critical realist stance in management, incorporation of a normative teleology, replacement of the deterministic and empirical approach in management science with a probabilistic and heuristic one, and inclusion of the religious horizon. These implications are then used to evaluate the resonances and conflicts arising from the comparison of management science with the teachings of GS. Based on this evaluation, normative principles for management are identified and consolidated to form the reorientation framework. The chapter also points out how this framework is suitable for management in the Church as well as in all other organizations. The workings of the reorientation framework are illustrated in Chapter 5 by applying it to two management tools which are frequently recommended in Catholic pastoral management literature: performance management systems, and marketing and customer service strategies. It is shown that the reorientation results in adjustments being made to these tools such that they better align with the nature and mission of the Church, while also facilitating more effective management and human flourishing when applied in all other organizations. The practical viability of the reoriented tool is also pointed out. Thereafter, based on the reorientation framework, a revised topical structure for Catholic pastoral management materials is proposed. Finally, a self-evaluation of this research project is presented, underscoring not only its contribution of the reorientation framework but also its demonstration of a systematic and fruitful inter-disciplinary method.

Abstract:

This study traces the evolution of the applied ecological discipline of range management in terms of the goals, methods, concepts, and criteria developed by range management for their science between 1897 and 1920. It argues, in contrast to the traditional view uÌ uat describes the knowledge-development process in applied science as just science applied to social problems, that wider social goals, values, concepts, and criteria play a definite role in shaping the applied science knowledge-development process.

The first generation of range management allowed the primary users of the knowledge in the wider society, the stockmen in the West and Southwest, to have a direct influence on the knowledge-development process. The next generation of scientists eliminated the stockmen's direct influence on the knowledge-development process, yet the stockmen still influenced that process indirectly in various ways.

This study concludes that an orientation towards the wider society that actually applies the knowledge is characteristic of range management and may be illustrative of illustrative of many applied sciences. Due to that orientation towards the wider society and to the wider society's influence on the scientist's choice of methods,concepts, and criteria, another characteristic of range management and possibly of other applied sciences is a tension in the knowledge development process between that orientation and the individual goals of scientists in their research.

Abstract:

The management of buildings has been currently gaining momentum in the construction industry. Public and private organisations which deal with managing facilities are interested in and needy to use any means to run their business as best as possible. Indeed, the life cycle of buildings is distributed in an asymmetric way, where the longest part regards the operational phase, leading to a huge importance to this stage. Traditionally, buildings used to be managed by using paper-based documents, personal experience, and manual analysis approaches. This implied loss of data and separated data silos, insights potentially biased in favour of knowledge, and time-consuming tasks. With the advent of the fourth industrial revolution, technology has boosted the opportunities to exploit disruptive tools to effectively manage buildings in a digital way and data has been put in the centre of attention. Although the digital building management can be extremely useful to manage the usage of data, organisations need appropriate methods, tools and skills to handle it. Nevertheless, most of organisations are not ready or capable to embrace innovations and still use old and traditional practices, even if error-prone and less efficient. As a result, the digital building management is not conducted at a reasonable and effective level. In addition to it, not only the abundance of data might be problematic, but also its format, as data is often stored using unstructured formats, leading to the impossibility to effectively exploit it. This leads to the following research questions: What are the methods and technologies that can be exploited in order to improve the building management? How should they be implemented and applied to reach such result? To what extent is data exploitable for the building management enhancement? The manuscript aims to improve the management of buildings. The first research objective concerns implementing the BIM method, defining crucial FM system features and describing how to generate digital models to lay the foundation for an effective digital management of buildings. The second one focuses on proposing solutions for space and maintenance management exploiting innovative technologies and techniques, namely Digital Twins and text-mining algorithms, in order to improve the management of buildings. The outcome of this research is a series of guidelines, which both public and private organisations can use, for enhancing building management.

In the emerging Web of Data, publishing stable and unique identifiers promises great potential in using the web as common platform to discover and enrich data in the ecologic sciences. With our collaborative e-Science platform “BEFdata”, we generated and published unique identifiers for the data repository of the Biodiversity – Ecosystem Functioning Research Unit of the German Research Foundation (BEF-China; DFG: FOR 891). We linked part of the identifiers to two external data providers, thus creating a virtual common platform including several ecological repositories. We used the Global Biodiversity Facility (GBIF) as well the International Plant Name Index (IPNI) to enrich the data from our own field observations. We conclude in discussing other potential providers for identifiers for the ecological research domain. We demonstrate the ease of making use of existing decentralized and unsupervised identifiers for a data repository, which opens new avenues to collaborative data discovery for learning, teaching, and research in ecology.

Abstract:

Internet applications have recently witnessed tremendous growth in terms of both size and complexity. Cloud computing is one of the several distributed technologies that have emerged to help meeting the objectives of these applications in terms of achieving high availability, performance and scalability.Platform as a Service (PaaS) is one kind of services provided by cloud solutions. These systems often follow a multi-tier architecture consisting mainly of a presentation tier, an application tier and a database tier. The volumes of data exchanged between the application tier and the database tier become huge, especially for enterprise level applications. As a result, the design of the database tier in cloud systems has to carefully address the scalability challenges rising from the huge data volumes. In this thesis, we propose a data distribution approach to improve the scalability of the database tier. Our approach is applied to a traditional single database server. It works by replacing the traditionally used single machine storage paradigm with a distributed storage paradigm. The suggested approach maintains the features that originally exists in the database system, and additionally provides the features of distribution and replication. Distributing the data storage helps improving the system fault-tolerance as it decreases the possibility of having a failure at the database server. It also helps resolve specific performance issues such as reducing the I/O usage and consecutively decreasing the possibility of an I/O bottleneck. Yet, it produces other performance challenges that need to be addressed. To prove the feasibility of our proposed approach, we use it to implement two extensions to the storage manager module of the PostgreSQL database system, using the HDFS distributed file system, and the HBase distributed key-value store.
Les applications Internet ont récemment connu une croissance considérable en termes de taille et de complexité. Afin de satisfaire la forte demande pour les ressources informatiques et les espaces de stockage, les technologies en distribution ont commencé à devenir plus impliquées dans les applications à grande échelle. Le Cloud Computing est l'une de ces nombreuses technologies qui ont émergé pour aider à atteindre les objectifs de ces applications, telles que la haute disponibilité, les performances et l'évolutivité.Platform as a Service (PaaS) est un type de service qui peut être fourni par les solutions de Cloud Computing. Ces systèmes suivent souvent une architecture multi-niveaux qui se compose principalement d'un niveau de présentation, un niveau d'application et d'un niveau de base de données. Les volumes de données échangées entre l'application et la base de données deviennent énormes en particulier pour les applications de niveau entreprise. En conséquence, la conception de la base de données dans les systèmes de Cloud Computing doit prendre en compte le challenge de l'évolution des quantités énormes de données. Dans cette mémoire, nous proposons une approche de distribution des données qui peuvent être utilisées pour améliorer l'évolutivité des bases de données. Nous proposons deux techniques qui peuvent être appliquées à un serveur de base de données unique traditionnelle.Ces techniques fonctionnent en remplaçant le paradigme traditionnel utilisant une seule machine de stockage avec un paradigme de stockage distribué. Les techniques proposées maintiennent les caractéristiques qui existaient à l'origine dans le système de base de données, et en plus fournissent les caractéristiques de la distribution et de la réplication. Ces deux fonctionnalités supplémentaires aident à améliorer le système de tolérance aux pannes, car ils diminuent la possibilité d'avoir une défaillance au niveau du serveur de base de données. La distribution du stockage permet de résoudre les problèmes de performances spécifiques, tels que la réduction de l'utilisation des entrées/sorties et consécutivement de diminuer la possibilité de saturation des entrées/sorties.Par ailleurs, cela produit d'autres défis de performances qui doivent être pris en compte. Pour prouver la faisabilité de nos techniques, nous les avons implémentées comme des extensions du module de gestion de stockage de la base de données PostgreSQL.

Abstract:

The thesis is concerned with organisational consulting, and the 'theories' which guide social and behavioural consultants in what they do. To preserve the 'integrity of the phenomena' the research has utilised an interviewing methodology to obtain accounts which reveal 'personal theories'. The aim has been to achieve an adequate phenomenology of consultants' ideas, rooted in their personal lives and organisational role situations, and not just to treat consultancy as the disembodied application of skills and knowledge. Consultants' ideas and practices can thereby be viewed in relation to their role-contexts, and can be seen as adapted to specific operating situations, particularly in the comparison of internal,commercial and academic consultants. Thus far, the study makes a substantive contribution to the understanding of social consultancy by locating ideas and practices in role circumstances. But such consultants are also ah occupational group, sharing a common role-context. The role is the product of wider organisational and societal processes. Beyond the specific slant given by differences in their immediate work-role, therefore, there appear common features in their working models. Two paradigms, the negotiative and systems, are identified and analysed as projections of consultants' role experiences which were also functional for clients, insofar as they developed the cohesion of managers as a group and their capacity to cope with problems facing organisations in the period 1960-79. Ideas and practices are thus viewed, ideologically, in relation to an historical period and social formation. By considering consultants' ideas, as ideology, in relation to their market situation (expressed in role) we confront a central question in social theory - the relation between ideas and the material structures and processes of society. At this point the study therefore attempts to connect the sociology of knowledge directly with the theory of ideology, and to make a substantive contribution to each.

ENGLISH ABSTRACT: Knowledge management is a fragmented and ambiguous management practice. This is evident from the plethora of definitions available for this field. The premise of this study is that different discourse patterns in knowledge management also contribute to the ambiguity. Four theoretical lenses describe the typical discourses that are associated with the formation of management practices, namely management innovation, umbrella construction, management fashion cycles and institutionalisation of management practice. The following propositions are indicative of the types of discourses involved – the rationale, business outcome, management niche, solution definitions and the means provided for the enactment of the practice. The discourses of seven proponents were analysed according to the above, viz. Verna Allee, Nancy Dixon, Leif Edvinsson, Ikujiro Nonaka, Laurence Prusak, David Snowden and Mathieu Weggeman. Three main patterns were identified based on the manner in which the discourses associated with the four theoretical lenses manifest in the analysed discourses. These patterns represent three different conceptualisations of knowledge management, namely - (i) Knowledge management as a meta-practice framework: the focus is on the assimilation and synthesis of the various knowledge-based practices that are part of other management practices (such as quality management), or practices that originate from fluid initiatives in organisations (e.g. the role of the librarian transforming to become a information broker), or practices that are defined through systematic experimentation (such as the potential of social media for intelligence analysis). (ii) Knowledge management as a platform and catalyst for systemic management innovation: the quest is to define new approaches that are appropriate to manage organisations as complex knowledge-based systems. These approaches should supersede management practices still rooted in Newtonian or mechanistic thinking. Knowledge management is regarded to be a revolutionary practice that proposes, conceptualises and diffuses such new approaches, e.g. value network management (Verna Allee) and the Cynefin framework (David Snowden). (iii) Knowledge management as a master idea or master narrative: this knowledge management discourse is about the theorisation of novel structural arrangements that emerge in organisations as a response to the new requirements of a knowledge-driven economy. This theorisation influences the thinking, premises and practices of various management fields, such as strategic planning, human resource management and organisational design.
AFRIKAANSE OPSOMMING: Kennisbestuur is ‘n gefragmenteerde en dubbelsinnige bestuurspraktyk. Dit is duidelik uit die menigvuldige definisies wat voorgehou word vir die veld. Die uitgangspunt van hierdie studie is dat verskillende diskoerspatrone in kennisbestuur ook tot die dubbelsinnigheid bydra. Vier teoretiese lense beskryf die tipiese diskoerse wat geassosieer word met die vorming van bestuurspraktyke, naamlik bestuursinnovasie, sambreelkonstruksies, bestuursmodesiklusse en die institutionalisering van bestuurspraktyke. Die volgende aspekte is ‘n aanduiding van die tipes diskoerse betrokke – die rasionaal, besigheidsuitkoms, bestuursnis, die definisie van die oplossing en die middele wat vir die implementering van die praktyke verskaf word. Die diskoerse van sewe voorstaanders is geanaliseer aan die hand van bogenoemde, naamlik Verna Allee, Nancy Dixon, Leif Edvinsson, Ikujiro Nonaka, David Snowden en Matthieu Weggeman. Drie hoofpatrone is geidentifiseer, gebaseer op die analise van die wyse waarin die vier teoretiese lense in die geselekteerde diskoerse manifesteer. Hierdie patrone verteenwoordig drie verskillende konsepsualiserings van kennisbestuur, naamlik - (i) Kennisbestuur as ‘n meta-praktykraamwerk: die fokus is op die assimilasie en sintese van die verskillende kennisgebaseerde praktyke wat deel is van ander bestuurspraktyke (soos kwaliteitsbestuur), of praktyke wat ontwikkel uit vloeibare inisiatiewe in organisasies (bv. die rol van die bibliotekaris wat transformeer na die van ‘n informasiemakelaar), of die definisie van nuwe praktyke aan die hand van sistematiese eksperimentering (soos die potensiaal van sosiale media vir intelligensie analise). (ii) Kennisbestuur as ‘n platform en katalisator vir sistemiese bestuursinnovasie: die strewe is om nuwe benaderings te definieer wat toepaslik is vir die bestuur van organisasies as komplekse kennis-gebaseerde stelsels. Hierdie benaderings moet bestuurspraktyke wat gewortel is in Newtoniaanse of meganistiese denke vervang. Kennisbestuur word beskou as ‘n revolusionêre praktyk wat nuwe benaderings voorstel, konsepsualiseer en versprei, soos Value Network Management (Verna Allee) en die Cynefin-raamwerk (David Snowden). (iii) Kennisbestuur as ‘n meesteridee of meesternarratief: hierdie kennisbestuurdiskoers omvat die teoretisering van nuwe strukturele reëlings wat, as ‘n reaksie op die nuwe vereistes wat ‘n kennisgedrewe ekonomie stel, in organisasies na vore kom. Hierdie teoretisering beïnvloed die denke, begronding en praktyke van verskeie bestuursvelde, soos strategiese beplanning, menslike hulpbronbestuur en organisasie-ontwerp.

Thesis (MBA)--Stellenbosch University, 2014.
Human resource management is a widely researched field. However, the research done in terms of small to medium-sized enterprises, is extremely limited, especially in South Africa. The aim of this research was to investigate human resource management practices in one such a company, and to develop a feasible action plan to improve on these practices. The chosen company, Task Applied Science (Pty) Ltd, is a medical research company based in Cape Town, South Africa. The data for the study was obtained through a literature review and interviews. The data from the literature review identified best practices and frameworks. This was combined with interviewing company employees as well as HRM practitioners in the medical field to not only identify problems, but to also suggest possible solutions. These solutions were compiled in a comprehensive action plan. As such, the results offer a workable solution for Task Applied Science, and can serve as example for all small to medium-sized enterprises. The literature review further showed that smaller companies tend to ignore the importance of human resource management due to the time and costs involved and the fact that they are focussed on the external environment rather than the internal. This cannot simply be remedied by implementing practices developed in large companies. Best practices need to be customised to fit the needs of the specific company. The findings showed that only certain human resource management practices were implemented in reaction to crises, or as needs arose. This, combined with the rapid growth and lack of structure, caused a breakdown in communication, transparency, and trust. Staff loyalty decreased because they felt that they were left in the dark. Both the company strategy and values became vague, and thus staff could not be aligned to it. Noteworthy was that the increase in policies and documentation did not cause employees to feel restricted, but rather that it created a feeling of security. The study made it abundantly clear that the human resources department needs to be treated as a strategic partner in the planning and execution of the company strategy; especially in terms of efficient change management. Their role is to communicate the strategic direction, while at the same time acting as an activist for the staff, voicing their needs and capabilities. The proposed action plan focused mainly on the company culture and the alignment of staff with the company’s business strategy. This was done by addressing issues such as company culture, communication, company values, and staff development. The plan offers practical solutions within each of these categories. Furthermore, it suggests solutions in terms of efficient staff recruitment and knowledge management. By implementing this plan the company will be able to increase the synergy between the business units within the company, eradicating silos, and establishing the staff as a competitive advantage. In addition to this, it will establish the human resources department as a credible partner for the staff in developing both their personal and professional lives.

Abstract:

Specialized laboratory information management systems (LIMS) are widely used by scientific research groups to store and manage experimental data. Smaller research laboratories' LIMS often lack support for automatic task execution, an omission that becomes more critical as experiments become increasingly automated. This thesis describes Exp-WF, a workflow management module specifically designed to be easily incorporated into a typical small-scale LIMS. Scientists describe the execution order of experiments as a workflow model. Exp-WF then automatically selects experiments for execution and dispatches them to the people or machines responsible for performing them. Exp-WF can be incorporated into an existing web-based LIMS in a non-intrusive way by using servlet filter technology to observe user actions and act upon them. Exp-WF uses agent-based technology with asynchronous communication to dispatch tasks to remote machines. This guarantees correctness even if the machines are not available all the time.

Abstract:

In this doctorate, I provide a balanced and collaborative approach to knowledge/value change between the contesting worldviews of indigenous knowledge and western science, termed 'synergistic'. My search for synergy is comparative and reconciliatory. This endeavours to overcome the popular pre-occupation with conflict and opposition. Rather, both difference and similarity are recognised. Through the comparison of such synergy, I argue that Māori development requires for its further advancement a focus not only on difference and conflict, but also on affinity and convergence. My primary concern is to establish a better understanding of the synergistic, adaptive strategies or indigenous innovation of Māori kaitiaki, environmental stewards. I investigate conflicting and converging Māori and western scientific conservation and use values in Aotearoa/New Zealand environmental governance and management regimes under the Resource Management Act 1991, with specific regard to indicator development. The balance of values were compared in ecological environmental governance, from five Aotearoa governmental authorities and three Māori river communities, utilising Māori and western social science methods. My focus on indicators pinpoints contesting knowledge/value change between the marginalisation of indigenous knowledge and dominance of western science. This seeks to highlight the potential viability of Māori kaitiakitanga, stewardship in global and national terms of sustainability. However, potential synergy is held back by a prevailing viewpoint of the indigenous worldview as backward, past-oriented and non-synergistic. An oppositional dogma predominates, which is a key problem to overcome. It spans world and national literature, resulting in considerable gaps in knowledge on synergy, conceptually, methodologically, empirically and analytically. This is addressed by an authoritative Māori synergistic standpoint from my own cultural lens and decolonised theorising, termed 'nuanced problem solving'. I articulate both worldviews in knowledge/value change through comparative, evolutionary, multi-dimensional, cross-cultural and inter-disciplinary research on synergy. My nuanced problem solving encapsulates the two main parts of the doctorate, whereby synergy is correlated between theory and social practice. Part one deals with value comparison in theory utilising high abstracted concepts and methods at the global level of environmental governance. Part two deals with value balance in social practice utilising medium abstracted and concrete empirical and analytical research at global, national, regional, district and cross-tribal levels of environmental governance. Potential synergy cross-cuts each part from high abstracted thought down and from the practical flax roots up. I argue that Māori advancement fluctuates between them. Drawing on cultural and theoretical leanings of the Māori synergistic standpoint, both a strong correlation with existing theory and expanded synergistic theorising was found. Due to the expansiveness of the research, these correlated findings only provide an embryonic understanding of potential synergy. A postscript describes my other work on synergy with five external agencies concerning foreshore, lakeside, wastewater, land disposal and carbon marketing kaitiakitanga. I argue that additional research on synergy is needed in order to further advance Māori.

Full text

Abstract:

Studies in the area of shipping freight risk measurement and management are limited and the understandings of the impact of freight volatility dynamics on the freight market remain insufficient and under-researched. The few studies that explore different approaches to measuring freight risk disagree on the most suitable measures and this is down to different interpretation of the underlying conditional variance for freight rates. Thus, the intention of this study is to contribute to the literature in the field of shipping freight risk studies. In this thesis tanker freight risk is measured using univariate and multivariate value-at-risk measures that are structured on a variety of single- and multi-state conditional variance models. Moreover, uncorrelated freight risk factors and conditional freight-beta are estimated through an orthogonal conditional variance and a dynamic freight-beta approach for a portfolio of freight returns, respectively. This thesis also investigates the hypothesis of the state dependency of freight dynamics through a conditional freight limitation framework, which distinguishes between ‘ship-owner’ and ‘cargo-owner’ markets, in particular pre- and during the most recent financial crisis. Furthermore, the short and long term effect of the financial crisis on freight markets are examined through a multi-state Markov switching-regime framework that provides thresholds indicating different freight bands for distinct market conditions. Thus, the hypothesis of variation in the freight-return relation is investigated on the basis that up and down market movements are defined as shipping agent controlled. Additionally, specific and systematic risks for the tanker market are extracted and compared across distinct tanker segments. Finally, a practical insight into shipping practitioners’ measurement and management of freight risk for different shipping segments is examined, where the directional accuracy and volatility of short- and long-term forward curves are assessed and compared against a general perception in the literature.

Abstract:

Thesis advisor: Eva M. Garroutte
Biomedicine has become a gatekeeper to numerous social opportunities and has gained power through the ritual inscription of individual bodies. Bodies serve as intermediaries between personal identities and biomedicine; individuals can reclaim bodies as sites of "identity projects" (Giddens 1991) to resist biomedical power. This project examines the intersection of the societal preoccupations with biomedicine, bodies, and identity through the lens of the religious and healing tradition of Christian Science. Christian Science theologically rejects biomedicine in favor of spiritual healing treatment. Christian Science is an especially appropriate venue for exploring relationships between biomedicine, bodies, and identities because its teachings require not only belief in the ineffectiveness of biomedicine but also embodied resistance to it. Drawing on the work of Foucault (1977), Giddens (1991), and Frank (1995) and using information gleaned from semi-structured interviews--averaging 1.5 hours in length--with 12 Christian Scientists, I argue that Christian Scientists use religious identities to (1) evade biomedical risk society, (2) resist external authority and reclaim bodies as sites of knowledge and power, and (3) build spiritual community

Abstract:

The goal of this research is to critically examine the nexus of risk management, decision-making, and knowledge management in an integrated framework, or triad. This research will examine this framework through the lens of managers in both human and scientific spaceflight missions at the National Aeronautics and Space Administration (NASA). It is intended to expose how coupling risk, knowledge and decision-making improve chances for mission success while potentially averting mishaps. Historical case studies of NASA Programs will be used to validate this assertion. Common risk management and knowledge management processes will be examined as enablers for risk-informed decision-making, particularly for residual risk acceptance decisions. Decision-making under normal programmatic conditions as well as during anomalous or mishap-related conditions will also be assessed.

Residual risk acceptance decision-making might be considered a special case of a requisite decision analysis model. In the context of NASA programs and projects these decisions are made throughout the lifecycle. They take on special significance however in the context of human spaceflight missions such as whether to: proceed with human-tended test and evaluation, to launch, or to respond to an off-nominal condition on-orbit. Finally, this dissertation offers a checklist for use by managers to improve residual risk acceptance decision competency within an organization.

Abstract:

The thesis is about an effort taken towards achieving context awareness by efficiently managing context information. The management of context spans from defining context attributes to triggering of actions resulting from a context state change. The design of the model is targeted towards creating a context aware environment for an adhoc users/services collaboration system. Contextual data are grouped and stored as profiles and database tuples depending on context themselves. The context management model gathers profile and preferences of mobile users and services and monitors changes that the entities undergo. These changes are reflected as actions on the related entities depending on the context change. The thesis proposes a design, which enables creating relationships between context attributes and deriving semantics out of them to describe a situation. Once the situation is resolved, the model identifies the tasks to be carried out in such situation and triggers relevant actions. The scope of context management model is restricted to entities that are present in a physical room. (Abstract shortened by UMI.)

Abstract:

Knowledge Management has been the subject of increasing focus over the last several years. Literature and research on the topic has grown as companies and organizations have come to realize that success is often determined by one's ability to create, disseminate, and embody knowledge in products and services. This realization has led to increased interest in examining the ways in which knowledge can be effectively created, identified, codified, disseminated, and retained. The field of Knowledge Management has emerged to address this need.

One of the obstacles that Knowledge Management seeks to overcome is the natural tendency in people to hoard knowledge. People often withhold knowledge when they feel it provides them with a competitive advantage over others. Many traditional management incentives and team structures create and perpetuate competitive environments that encourage knowledge hoarding. Knowledge Management also seeks to find ways to reduce the impact of employee turnover. When an employee leaves a company or organization, the knowledge they possess often goes with them. This loss can potentially have a negative impact on the productivity and quality of the company or organization. Knowledge Management seeks to find ways to minimize loss of knowledge when an employee leaves a company or organization.

Pair programming is a practice that holds promise for overcoming some of the challenges faced by Knowledge Management. In pair programming, two programmers work side-by-side at one computer collaborating on the same design, algorithm, code, or test. The continual interaction between pair programmers would seem to provide an environment that promotes knowledge sharing, and collaborative knowledge discovery. Additionally, through pair rotation, in which pairs change partners fairly often, tacit knowledge might be spread more effectively through face-to-face communication than by documentation, databases, or other means.

This research examines pair programming in the realm of Knowledge Management, positing the following hypotheses:Pair programming reduces the tendency of people to hoard knowledge.Pair programming reduces the impact of employee turnover.Pair programming is an effective means of knowledge dissemination and knowledge retention that has a positive influence on the Knowledge Management practices of a company or organization.

These hypotheses are tested through the use of a survey of individuals in technology research, development, and service. Analysis of the survey results provided no conclusive evidence to either support or disprove the hypothesis that pair programming reduces the tendency of people to hoard knowledge. The results indicate support for the hypothesis that pair programming reduces the impact of employee turnover, although not statistically significant. And finally, the survey results indicate with statistical significance that pair programming is an effective means of knowledge dissemination and retention, with a positive influence on the Knowledge Management practices of a company or organization.

Abstract:

The purpose of this study was to describe how journalists do research for their articles and whether there is a need to create a knowledge bank of the material that journalists use for writing these articles. I also looked at how knowledge management could be used at a daily newspaper to add value to the information used by the journalists. The thesis is based on four interviews with journalists, a literature review and a practical project. I helped a journalist with his information seeking and later tried to organize the material. This project gave me an understanding of how varying the material that journalists use is and how difficult it would be to try to organize it in order to create an organizational knowledge resource of the material. The study shows that journalists use a lot of information in their work and a big part of their job consists of information seeking. A lot of the retrieved information is not used more than once. The study shows that if the material was organized and made available for other journalists at the newspaper, it would make journalists work more effective. The results also show that there are some knowledge management tools available at the newspaper but these are not used for knowledge management purposes. Journalists also need to change their way of thinking about their profession from the industrial era to the information and knowledge era in order to make knowledge management succeed and benefit the organization and its employees.

Abstract:

Online identities play critical roles in the current Internet world. One of the virtues of traditional online identities, in forms of pseudonyms, is the privacy protection of online users. Users can create as many anonymous identities as they want with only an email account. However, the anonymity itself could be a limitation because of the lack of accountability.The prevalence of online social networks inspires us to create a social pseudonym framework through which it is possible to determine proximity between pseudonyms while retaining privacy. The basic idea of this work is mapping the online social network into a geometric space and assigning each user a coordinate according to the relationship with his/her neighborhood. The coordinate itself will not disclose any information of a user, but by computing the coordinates distance, proximity between users could be estimated with a certain probability. I evaluated the framework with several real online social network datasets. The results indicate that the proposed framework is promising under certain conditions.
Dans le contexte d'Internet, les identifiants des usagers jouent un rôle critique. L'un des avantages des identifiants traditionnels, soient les pseudonymes, est de fournir une protection de la vie privée des usagers. Les usagers peuvent créer autant d'identifiants anonymes qu'ils le désirent simplement en utilisant une adresse courriel. Par contre, l'anonymité même peut devenir un facteur limitant dû à la déresponsabilisation des usagers. L'importance des réseaux sociaux en ligne nous inspire à créer un système de pseudonymes sociaux à travers lequel il sera possible de déterminer la proximité entre pseudonymes tout en conservant la confidentialité. Le système se base sur l'idée d'associer un réseau social à un espace géométrique et d'assigner des coordonnées à chaque usager qui dépendent de la relation entre l'usager et son voisinage. Les coordonnées elles-même ne fournissent aucune information confidentielle à propos d'un usager. Cependant, en calculant la distance entre différentes coordonnées, la proximité entre usagers peut être estimée avec une certaine probabilité. J'ai évalué le système avec des données provenant de réseaux sociaux réels. Les résultats indiquent que le système proposé, en imposant certaines conditions, est prometteur.

Hierdie uitdagings tel onder die faktore wat dienslewering negatief beinvloed. Alhoewel die Departement van Behuising ongeveer twee miljoen en sewe honderd duisend huise gelewer het, sedert 1994 was daar nog steeds uitdagings. Gepaardgaande met swak dienslewering, het die Departement ook gesukkel om bates soos inligting, kennis, inligtingstegnologie en menslike hulpbronne te bestuur. Alhoewel dit uitgebreide beleggings gemaak het in inligting tegnologie, veral in die ondersteuningsdienste, het die departement nog nie die tegnologie ten volle benut nie. Die tesis poog om die positiewe aspekte te ontdek wat deur die toepassing van kennisbestuur binne die behuisingsektor oor al drie regeringsvlakke teweeggebring kan word. ‘n Vraelys is versprei onder beamptes wat die bestaande behuisingsinformasie-sisteme gebruik in die areas van behuisingsubsidie administrasie, monitering en evaluering en projekbestuur afdelings in die behuisingsektor. Gebaseer op die bevindinge van die vraelys word ‘n kennisbestuursmodel vir die behuisingsektor voorgestel wat dienslewering kan bevorder.

Abstract:

ENGLISH ABSTRACT: Most people working in the software industry recognise that developing software to predictable schedules is risky and not easy. They experience problems to estimate how long the development of software will take. Underestimation leads to under staffing and setting too short a schedule. That in turn leads to staff burnout, low quality and missed deadlines. Overestimation can be almost as bad: Parkinson's Law that work expands to fill available time comes into action, which means the project will take as long as estimated even if overestimated. Currently people do no put in much effort to estimate jobs and therefore projects take as long as they take. Methods to manage uncertainty lead to putting in excessive safety and then wasting it. Business usually presents a target for the project with tremendous pressure for low 'estimates' during the bidding process and in the end this target becomes the plan. Best practice appears to manage the gap between this target and the estimate as a risk on the project. Without an efficient work breakdown structure (WBS) one cannot accurately estimate. Subject experts should help the project manager to plan the detail of how the work should be done. A functional design by a systems architect helps to break down the technical tasks. This is very important because omitted tasks will not be estimated for. The first step towards sound estimates is to estimate the size. This is extremely difficult at the initial phase but can be overcome if the company store history of size and completion time in a repository. Although lines of code are most often used as a size measure, function points or function blocks appear to be better, especially for the initial estimate. If an organisation has not kept historic data, now is the time to start doing it. The suggested procedure to follow before starting to gather information, is to define what is going to be kept (the norms), to delimit the defined data, to discipline the collection, to deposit it in an established repository and to deliver it in readily usable format. The tool used for storing these metrics must provide building in factors that influence effort like complexity, skills level, elapsed time, staff turnover, etc. There are many different techniques for estimation. The best option seems to use a combination of estimates and include developer opinion and a mathematical method like function point analysis. Estimation of software development, like all other work processes, need management control and this is called metrics management. This process includes establishing some kind of modeL Empirical models, based on a database with data stored by ones own company, give the best results. Two very good models are the Putnam model and the Parr model (for smaller projects). Even the best model and process is never perfect. Therefore the estimation process must be continuously monitored by comparing actual duration times to estimates. Be careful with feedback on how accurate estimates were. No feedback is the worst response. Carefully discussing the implications of underestimation and putting heads together to solve the problem appears to be the best solution.
AFRIKAANSE OPSOMMING: Die meeste mense in die sagteware industrie erken dat om sagteware te ontwikkel teen voorspelbare tydskedules, gevaar inhou en nie maklik is nie. Hulle ondervind probleme om te skat hoe lank die ontwikkeling van sagteware hulle gaan neem. Onderskatting lei tot te min hulpbronne en te kort skedules. Dit veroorsaak uitbrand van mense, lae kwaliteit en einddatums wat nie gehaal word nie. Oorskatting is byna net so erg. Parkinson se Wet dat werk geskep word om beskikbare tyd te vul, kom in aksie en aan die einde beteken dit die projek neem so lank as wat geskat is, selfs al is dit oorskat. Huidiglik doen mense nie veel moeite om tyd te skat op take nie en daarom neem projekte so lank as wat dit neem om te voltooi. Metodes om onsekerheid te bestuur lei tot die byvoeg van oormatige veiligheidstyd net om dit daarna weer te verkwis. Die besigheid verskaf gewoonlik 'n mikpunt vir die projek met geweldige druk vir lae skattings tydens bieery en op die ou end raak hierdie mikpunt die projekplan. Die beste manier om dit die hoof te bied is om die gaping tussen hierdie mikpunt en die skatting te bestuur as 'n projek risiko. Niemand kan akkuraat skat sonder 'n effektiewe metode van werk afbreek nie. Vakkundiges behoort die projekbestuurder te help om die detail van hoe die werk gedoen gaan word, te beplan. 'n Funksionele ontwerp deur 'n stelselsargitek help om die tegniese take verder af te breek. Dit is baie belangrik aangesien take wat uitgelaat word, nie in die skatting ingesluit gaan word nie. Die eerste stap om by gesonde skattings uit te kom, is om grootte te skat. Dit is besonder moeilik in die aanvanklike fase, dog kan oorkom word indien die maatskappy geskiedenis stoor van hoe groot voltooide take was en hoe lank dit geneem het. Alhoewel Iyne kodering die mees algemeenste vorm van meting van grootte is, Iyk dit asof funksie punte of funksie blokke beter werk, veral by die aanvanklike skatting. Indien 'n organisasie nie historiese data stoor nie, is dit nou die tyd om daarmee te begin. Die voorgestelde prosedure om te volg voordat informasie gestoor word, is om te definieer wat gestoor gaan word (norme te bepaal), om die data af te baken, dissipline toe te pas by die insameling, dit te stoor in 'n gevestigde databasis en dit beskikbaar te stel in bruikbare formaat. Die instrument wat gebruik word om hierdie syfers te stoor moet voorsiening maak vir die inbou van faktore wat produksie beinvloed, soos kompleksiteit, vlak van vaardigheid, verstreke tyd, personeel omset, ens. Daar bestaan menige verskillende tegnieke vir skatting. Die beste opsie blyk 'n kombinasie van skattings te wees. Die opinie van die programmeur asook een wiskundige metode soos funksie punt analise, behoort deel te wees hiervan. Soos alle ander werksprosesse, moet skattings vir sagteware ontwikkeling ook bestuur word en dit word metrieke bestuur genoem. Hierdie proses behels dat daar besluit moet word op een of ander model. Empiriese modelle gebaseer op 'n databasis waarin data gestoor word deur die maatskappy self, gee die beste resultate. Twee baie goeie modelle is die Putnam model en die Parr model (vir kleiner projekte). Selfs die beste model en proses is egter nooit perfek nie. Die estimasie proses moet dus voortdurend gemonitor word deur werklike tye met geskatte tye te vergelyk. Wees versigtig met terugvoer aangaande hoe akkuraat skattings was. Geen terugvoer is die ergste oortreding. Die beste oplossing skyn te wees om die implikasie van die onderskatting met die persoon wat die skatting gedoen het, te bespreek en koppe bymekaar te sit om die probleem op te los.

Abstract:

Global scale identity management attempts to be the system of identifying and authenticating entities such as people, hardware devices, distributed sensors and actuators, and software applications when accessing critical information technology (IT) systems from anywhere. The term global-scale is intended to emphasize the pervasive nature of identities and implies the existence of identities in federated systems that may be beyond the control of any single organization. The purpose of this research was to analyze the current state of Global Scale Identity Management. Today, news of security breaches is far too commonplace. The results reveal that global scale identity management would have a positive effect on the individual person, businesses, government agencies, and institutions. However for global scale identity management to be operational much work remains. The remaining work is split between the physical realm, i.e., biometric equipment, quantum resistant cryptography, and the abstract realm, i.e., legal considerations, social and cultural mores, privacy issues, and international considerations. The research concluded that humans are repeatedly the weak link in password security that ultimately undermines a system’s stability. For the short term, the best suggestion is to use password managers and have systems disallow poor password choices. For the long-term build infrastructures with quantum resistant cryptography interfacing with the ubiquitous smartphone to provide multifactor authentication.
