The motivation to this master`s thesis is an increasing demand on evaluation of expertise report in conformity with requirements of internationally accepted standards as well as with national legal regulations. This master`s thesis is focused on defining of requirements of International Valuation Standards – IVS. The objective of the introductory study of this thesis is an effort to provide overview of the structure, the history and development of International Valuation Standards – IVS. The introductory study points out that the IVS standard is not stationary one, but shows the importance to keep the continuous track and analyze other possible information sources in connection to it. The main objective is to analyze the principal requirements of International Valuation Standards for expert as a person, expertise activity and required features of expertise report. The gained information is processed on the base of an expertise system approach, where the expertise is interpreted as a structured object with principal features: expertise object, expertise problem, expertise activity, expertise report and expert. Established findings are then analyzed regarding to such interpreted system approach of expertise and applied in the determination of type of approach which an expert should follow in the procedure of making out an expertise report of property valuation. Finally, an example expertise report for valuation of real estate is compiled. Such expertise report could be considered in conformity with national legal regulation as well as with requirements of International Valuation Standards – IVS. The expertise report is a practical example of findings of this master`s thesis.

Le travail de recherche qui suit vise à l’obtention d’une méthodologie opératoire propre à faire évoluer la culture organisationnelle d’une firme dans le domaine de l’activité inventive, en particulier en opérant un transfert culturel à partir du monde académique. Il s’agit de construire un procédé de recueil et d’explicitation des connaissances inventives ayant abouti à une conception nouvelle, puis à exploiter en interne les résultats de ce premier procédé en appliquant ceux-ci à un second procédé ayant la dimension d’un apprentissage organisationnel. Le dispositif expérimental présenté a visé à réaliser la validation des hypothèses formulées. L’étude de cas dans notre organisation a permis de concrétiser, sur la base du bilan de l’évolution temporelle du patrimoine intellectuel inventif, l’approche de la créativité stimulée par les connaissances dans un cadre limité à trois domaines de connaissance et où l’on vise une innovation incrémentale. Ce mécanisme met en jeu individuellement et collégialement un ensemble d’acteurs impliqués dans l’inventaire préalable du patrimoine intellectuel inventif et dans son évolution stratégique au sens de l’organisation. En outre, ce travail introduit une vision peu commune de l’activité de R & T d’une organisation industrielle, vision où l’approche par la connaissance non contextuelle se substitue aux approches contextuelles usuelles par produits et services. Cette méthodologie opératoire s’appuie sur une approche conceptuelle de la créativité appliquée à la création de connaissances inventives. Cette création de connaissances est interprétée comme une mutation épistémologique déclenchée par la nature profondément paradoxale de la créativité. Le (futur) créateur doit porter en lui l’essence d’une oeuvre constituant la future création, la créativité lui permettant d’identifier cette essence par abstraction et l’inventivité lui permettant de donner performativement une Forme à cette abstraction. La mise au jour de liens puissamment opératoires entre des domaines peu mis en regard jusqu’alors, ceux de la Créativité/Inventivité, du Patrimoine Intellectuel et de l’Ingénierie des Connaissances fournit de solides fondations à l’approche conceptuelle de la création de connaissances inventives, ainsi qu’à de nombreuses perspectives de recherches supplémentairesThe following research work aims at getting an operational methodology able to make firm’s organizational culture progress in the inventive activity field, especially through a cultural transfer from academic world. The point is first building a process gathering and making explicit inventive knowledge which succeeded in a new design. Then, results coming out of this first process are applied to a second process featuring organizational learning. We described an experimental plan dedicated to the validation of the research hypotheses that we formulated. The case study based on our own organization was the opportunity to get a first operational validation of Knowledge-based innovation method applied to a 3-knowledge domain configuration for incremental innovation. Creativity stimulation was operated through the time-evolution synthesis of intangible inventive intellectual corpus. This mechanism both individually and collectively involves numerous actors already solicited for the preliminary inventory of inventive intellectual corpus and for its strategic evolution according to the firm.Moreover, this work brings an usual view on industrial R & T activity, where non contextual knowledge approach is substituted to conventional contextual approach bases on products. This operational methodology is based on a conceptual approach of creativity applied to the generation of inventive knowledge, which is seen as an epistemological mutation triggered by the most paradoxical nature of creativity. The (future) creator must house in himself the essence of intellectual work which will be the future creation: creativity allows him to identify this essence by abstraction and inventivity allows him to performatively give a Form to this abstraction. By revealing strongly operative links between poorly linked domains(Creativity/Inventivity, Intellectual Corpus, Knowledge Management), solid foundations are brought to the conceptual approach of inventive knowledge generation and to numerous perspectives of extra research

Durand, William. "Automated test generation for production systems with a model-based testing approach." Thesis, Clermont-Ferrand 2, 2016. http://www.theses.fr/2016CLF22691/document.
Full textAbstract:
Ce manuscrit de thèse porte sur le problème du test basé modèle de systèmes de production existants, tels ceux de notre partenaire industriel Michelin, l’un des trois plus grands fabricants de pneumatiques au monde. Un système de production est composé d’un ensemble de machines de production contrôlées par un ou plusieurs logiciels au sein d’un atelier dans une usine. Malgré les nombreux travaux dans le domaine du test basé modèle, l’écriture de modèles permettant de décrire un système sous test ou sa spécification reste un problème récurrent, en partie à cause de la complexité d’une telle tâche. De plus, un modèle est utile lorsqu’il est à jour par rapport à ce qu’il décrit, ce qui implique de le maintenir dans le temps. Pour autant, conserver une documentation à jour reste compliqué puisqu’il faut souvent le faire manuellement. Dans notre contexte, il est important de souligner le fait qu’un système de production fonctionne en continu et ne doit être ni arrêté ni perturbé, ce qui limite l’usage des techniques de test classiques. Pour pallier le problème de l’écriture de modèles, nous proposons une approche pour construire automatiquement des modèles depuis des séquences d’événements observés (traces) dans un environnement de production. Pour se faire, nous utilisons les informations fournies par les données échangées entre les éléments qui composent un système de production. Nous adoptons une approche boîte noire et combinons les notions de système expert, inférence de modèles et machine learning, afin de créer des modèles comportementaux. Ces modèles inférés décrivent des comportements complets, enregistrés sur un système analysé. Ces modèles sont partiels, mais également très grands (en terme de taille), ce qui les rend difficilement utilisable par la suite. Nous proposons une technique de réduction spécifique à notre contexte qui conserve l’équivalence de traces entre les modèles de base et les modèles fortement réduits. Grâce à cela, ces modèles inférés deviennent intéressant pour la génération de documentation, la fouille de données, mais également le test. Nous proposons une méthode passive de test basé modèle pour répondre au problème du test de systèmes de production sans interférer sur leur bon fonctionnement. Cette technique permet d’identifier des différences entre deux systèmes de production et réutilise l’inférence de modèles décrite précédemment. Nous introduisons deux relations d’implantation : une relation basée sur l’inclusion de traces, et une seconde relation plus faible proposée, pour remédier au fait que les modèles inférés soient partiels. Enfin, ce manuscrit de thèse présente Autofunk, un framework modulaire pour l’inférence de modèles et le test de systèmes de production qui aggrège les notions mentionnées précédemment. Son implémentation en Java a été appliquée sur différentes applications et systèmes de production chez Michelin dont les résultats sont donnés dans ce manuscrit. Le prototype développé lors de la thèse a pour vocation de devenir un outil standard chez MichelinThis thesis tackles the problem of testing (legacy) production systems such as those of our industrial partner Michelin, one of the three largest tire manufacturers in the world, by means of Model-based Testing. A production system is defined as a set of production machines controlled by a software, in a factory. Despite the large body of work within the field of Model-based Testing, a common issue remains the writing of models describing either the system under test or its specification. It is a tedious task that should be performed regularly in order to keep the models up to date (which is often also true for any documentation in the Industry). A second point to take into account is that production systems often run continuously and should not be disrupted, which limits the use of most of the existing classical testing techniques. We present an approach to infer exact models from traces, i.e. sequences of events observed in a production environment, to address the first issue. We leverage the data exchanged among the devices and software in a black-box perspective to construct behavioral models using different techniques such as expert systems, model inference, and machine learning. It results in large, yet partial, models gathering the behaviors recorded from a system under analysis. We introduce a context-specific algorithm to reduce such models in order to make them more usable while preserving trace equivalence between the original inferred models and the reduced ones. These models can serve different purposes, e.g., generating documentation, data mining, but also testing. To address the problem of testing production systems without disturbing them, this thesis introduces an offline passive Model-based Testing technique, allowing to detect differences between two production systems. This technique leverages the inferred models, and relies on two implementation relations: a slightly modified version of the existing trace preorder relation, and a weaker implementation proposed to overcome the partialness of the inferred models.Overall, the thesis presents Autofunk, a modular framework for model inference and testing of production systems, gathering the previous notions. Its Java implementation has been applied to different applications and production systems at Michelin, and this thesis gives results from different case studies. The prototype developed during this thesis should become a standard tool at Michelin

Full textAbstract:
Context. Gene regulatory network (GRN) inference is an important and challenging problem in bioinformatics. A variety of machine learning algorithms have been applied to increase the GRN inference accuracy. Ensemble learning methods are shown to yield a higher inference accuracy than individual algorithms. Objectives. We propose an ensemble GRN inference method, which is based on the principle of Mixture-of-Experts ensemble learning. The proposed method can quantitatively measure the accuracy of individual GRN inference algorithms at the network motifs level. Based on the accuracy of the individual algorithms at predicting different types of network motifs, weights are assigned to the individual algorithms so as to take advantages of their strengths and weaknesses. In this way, we can improve the accuracy of the ensemble prediction. Methods. The research methodology is controlled experiment. The independent variable is method. It has eight groups: five individual algorithms, the generic average ranking method used in the DREAM5 challenge, the proposed ensemble method including four types of network motifs and five types of network motifs. The dependent variable is GRN inference accuracy, measured by the area under the precision-recall curve (AUPR). The experiment has training and testing phases. In the training phase, we analyze the accuracy of five individual algorithms at the network motifs level to decide their weights. In the testing phase, the weights are used to combine predictions from the five individual algorithms to generate ensemble predictions. We compare the accuracy of the eight method groups on Escherichia coli microarray dataset using AUPR. Results. In the training phase, we obtain the AUPR values of the five individual algorithms at predicting each type of the network motifs. In the testing phase, we collect the AUPR values of the eight methods on predicting the GRN of the Escherichia coli microarray dataset. Each method group has a sample size of ten (ten AUPR values). Conclusions. Statistical tests on the experiment results show that the proposed method yields a significantly higher accuracy than the generic average ranking method. In addition, a new type of network motif is found in GRN, the inclusion of which can increase the accuracy of the proposed method significantly.Genes are DNA molecules that control the biological traits and biochemical processes that comprise life. They interact with each other to realize the precise regulation of life activities. Biologists aim to understand the regulatory network among the genes, with the help of high-throughput techonologies, such as microarrays, RNA-seq, etc. These technologies produce large amount of gene expression data which contain useful information. Therefore, effective data mining is necessary to discover the information to promote biological research. Gene regulatory network (GRN) inference is to infer the gene interactions from gene expression data, such as microarray datasets. The inference results can be used to guide the direction of further experiments to discover or validate gene interactions. A variety of machine learning (data mining) methods have been proposed to solve this problem. In recent years, experiments have shown that ensemble learning methods achieve higher accuracy than the individual learning methods. Because the ensemble learning methods can take advantages of the strength of different individual methods and it is robust to different network structures. In this thesis, we propose an ensemble GRN inference method, which is based on the principle of the Mixture-of-Experts ensemble learning. By quantitatively measure the accuracy of individual methods at the network motifs level, the proposed method is able to take advantage of the complementarity among the individual methods. The proposed method yields a significantly higher accuracy than the generic average ranking method, which is the most accurate method out of 35 GRN inference methods in the DREAM5 challenge.

The professional world, as well as, the single employee faces multiple challenges in daily routine. To improve individual health along with the whole organization, interventions are conducted. However, a summary of requirements for successful initiatives are not existing. The study describes a Group Concept Mapping approach with multinational and multidisciplinary experts in the area of organizational development. From 112 single requirements for successful interventions, finally the following 15 clusters are identified, which function as a framework for the implementation of interventions: (1) Context alignment/intervention fit, (2) Continual modification, (3) Assessment (situation & risk)/ recurrent, (4) Planning/structural change processes, (5) Active collaboration from different stakeholders, (6) Transparent communication, (7) Pay attention to participants, (8) Leadership, (9) Supportive climate for learning, (10) Persistence/ complexity, (11) Point of departure/prerequisite, (12) Impact (what kind & monitoring), (13) Perceived value, (14) Variation and (15) Single Statements. The provided knowledge can be used by practitioners -especially consultants -in the process of planning, conducting and evaluating a successful initiative.

Principal assumptions are made during the early stage of the design process, fixing 70% to 80% of total building costs and most of a building's architectural and environmental qualities. The demands of any one constraint impose a whole set of assumptions that often result in a design that is satisfactory along only a few dimensions. Ruling out many alternatives at a stroke, such assumptions relieve the architect from exhaustively reviewing variations by removing opportunities from consideration. Both the power and crudeness of assumptions increase as constraints multiply and conflict. Having the ability to quickly and thoroughly evaluate assumptions and their consequences would allow architects to intelligently challenge and reform those assumptions and, as a result, to explore a broader range of possibilities for any particular design. This is particularly important in complex projects where the architect's primary role may be to orchestrate experts. This role is not insignificant, for the experts' recommendations will necessarily be bounded by their own concerns and will often conflict. The architect must assign values to design consequences and must provide the assumptions that the experts will base their recommendations on. The architect, then, focuses on making assumptions and interpreting evaluations. But assumptions are of ten outside analysis; rules of thumb, based on experience, generally prevail. Knowledge- based computer expert systems are a promising path of research for the support of conscious and explicit assumption-making. The crucial question for this technology and the central topic of this thesis is how to structure knowledge for use in such a system. My primary goal is to offer a representation of the knowledge involved in window design (a simpler and somewhat isolable subset of building design), a representation comprehensive enough to be useful, but also flexible enough to support differing design processes and decision sequences.

Fontenele, Marcelo Paiva. "Designing a method for discovering expertise in cyber security communities : an ontological approach." Thesis, University of Reading, 2017. http://centaur.reading.ac.uk/71325/.
Full textAbstract:
Cyber security aims to protect our connected society from threats affecting services that rely on cyberspace. The pervasive nature of those threats requires a collaborative engagement in which a heterogeneous set of stakeholders request or provide security services. One of the major challenges in current cyber security initiatives is to place skilled people wherever needed whilst reducing the overall knowledge gap. Thus, in order to orchestrate roles in such a complex and dynamic environment, a novel approach to discover talent within the cyber security community is required. This PhD research addresses this challenge by devising a conceptual model and an ontological methodology, which aids a robust discovery of the fittest expertise driven by the specific needs of cyber security projects, as well as benchmarking expertise shortages. Talent management, knowledge management and organisational modelling theories provide the theoretical foundations upon which the cyber security community is articulated. Mixed methods were performed within a cyber security community to triangulate findings in the literature, test the method and appraise the solution. The method for discovering expertise in cyber security communities (DECYSE) is capable of delivering a seamless solution for processes involving expertise discovery. This method enables learning from previous projects; supports selection, ranking and assessment of experts according to specified requirements in a project profile; and provides indicators to measure knowledge gaps and shortages in the cyber security community. The DECYSE method is robust and underpinned by analytical techniques, considering complex interactions and perspectives from the actors involved. In order to promote ongoing improvement on the method itself, this thesis also details the conceptual model which articulates the requirements for developing DECYSE. A round of experiments was successfully conducted, where a team of three experts, out of sixty-six participant profiles, met the criteria in a cyber security project. The method was also positively appraised by a board of experts working with strategic CS projects. DECYSE enables ongoing improvement and contributes to both theory and the cyber security community.

The use of systems that span many knowledge domains is becoming more common as technology advances, requiring expert-performance in a domain from users who are usually not experts in that domain. This study examined a means of communicating expertise (in system operation and fault diagnosis) to non-experts and furthering the understanding of expert mental models. It has been suggested that conceptions of abstract models of system-functions distinguish expert performance from non-expert performance (Hanisch, Kramer, and Hulin, 1991). This study examined the effects on performance of augmenting a simple control panel device with a model of the functions of the device, interacting with the model, and augmenting the device with graphically superimposed procedural indicators (directions). The five augmented display conditions studied were: Device Only, Device + Model, Device + Procedural Indicators, Interactive Model, and Interactive Model + Procedural Indicators. The device and displays were presented on a PC workstation. Performance measures (speed and accuracy) and subjective measures (questionnaires, NASA TLX, and structured interviews) were collected. It was expected that participants who interact with the device + procedural indicators would exhibit the shortest performance time and least errors; however, those who interacted with the simplest display (device only) were fastest and exhibited the least errors. Results of this study are discussed in terms of building a mental model and identifying situations that require a mental model.Ph. D.

Full textAbstract:
The statistical mentor system incorporates a knowledge base into an educational tool for novices in statistical decision making to use in choosing a statistical technique. The novices are students in a business school curriculum who are expected to learn the basic statistical processes in business applications. The purpose of the system is to stimulate learning of the data analysis process on the part of the novice, usually a difficult task. The system acts as a consultant to the novice and approaches the task using a top-down problem solving strategy rather than the traditional bottom-up strategy used by novices. The heart of the system is the rule base for differentiating between statistics. These rules were built by gathering expertise from two experts in statistical analysis. The rules are based on five questions which the data can answer, as well as the type of data, the number of variables, and any dependent/independent relationships which exist between the variables. The knowledge base consists of five rule sets and can be represented either by condition/conclusion rules or by a set of multi-dimensional tables. Twenty-nine statistics and the rules for choosing them are in the rules sets. The knowledge base was used to define the logic incorporated in the consultant system in order to aid the user in selecting a correct technique. A dialogue mode is employed in the consultant to determine which conditions are true for the problem and data set. The rule sets are then checked to find the conclusion satisfying the conditions. The computer mentor was tested against the usual textbook mentor method (search through a textbook until one finds a statistic that looks promising) with two different groups of subjects, 25 undergraduates and 19 doctoral students. The results were that the computer-assisted students in both samples correctly solved a larger proportion of problems and had a higher average number of problems correct than did the textbook assisted groups.

Full textAbstract:
The field of expertise studies offers several models from which to develop training programs that accelerate the development of novice performers in a variety of domains. This research study implemented two methods of expertise-based training in a course to develop undergraduate peer academic coaches through a ten-week program. An existing training curriculum was enhanced by implementing results gleaned from a preliminary expert performance study, in which the superior, reproducible performance of seasoned professionals (counselors and academic advisors working with undergraduate students at a large Midwestern research university) was analyzed. Part-task, observational training activities were created for the expertise-based (XBT) training group while whole-task, simulation-based activities were created for the expert performance based (ExPerT) training group. Trainee performance in four targeted skill sets (asking questions, reflective listening, noticing reactions, and providing feedback) indicated few significant differences between the XBT and ExPerT training groups. The ExPerT group demonstrated a greater number of evocative statements, aimed at helping coaching clients change behaviors. Overall, the utility of the expert performance approach in developing training in various domains is promising, particularly if an appropriate balance of part-task and whole-task training activities can be found.

While evidence from clinical and functional neuroimaging domains converges on a notion that auditory-motor networks can be remodeled functionally and structurally in response to experiences, studies that seek to evaluate these hypotheses by combining behavioral, functional, and structural measures are rare. Given relatively recent advances in neuroimaging, e.g. diffusion-tensor imaging (DTI) and functional neuroimaging methods (fMRI), it is now possible to structurally and functionally analyze these networks, as well as make inferences about them in situations where the networks are either functionally compromised by an auditory-motor feedback disorder, or structurally enhanced by an intense long-term auditory-motor training regimen. To this end, a three-fold course of study has been undertaken: (1) a between-group comparison of the structural aspects of the arcuate fasciculus (a prominent white-matter fiber tract that reciprocally connects the temporal and inferior frontal lobes and is thought to be important for auditory-motor interactions) of singers and those of matched nonsinging musicians, in order to evaluate the hypothesis that singers will exhibit structural differences specifically for aspects of vocal output that require rapid temporal processing and precise sound-motor matching. (2) a within-subject fMRI comparison of responses of young adults (non-musicians) to auditory feedback that is either unperturbed or shifted in pitch while they perform a pitch-matching task, to ascertain a functional network related to perceiving and perhaps compensating for mismatched auditory feedback. (3) a within-subject pilot study of the network ascertained in (2), now in a smaller group of young adults with an auditory-motor disorder/disconnection syndrome commonly referred to as tonedeafness (TD) or congential amusia (a conditioned marked by a high pitch discrimination threshold as well as readily apparent difficulty in matching pitches), in order to provide insight into how this network might behave in a state of long-term disorder. While this work corroborates previous work in clinical, behavioral, and neuroimaging domains, and sheds light on the organization of these auditory-motor networks (structurally and functionally) in the normal population, it also aids in understanding how these networks may be remodeled and optimized (structurally) in response to intense long-term training, how they adapt to an acutely compromised state (i.e. when input to the network is compromised or perturbed), as well as how they may adapt functionally in a chronically compromised state (i.e. tonedeafness). Taken together, these observations help to explain the functioning of the auditory-motor network in normal individuals and those with communication disorders, as well as well as shedding light on possible mechanisms of recovery as they participate in an intensive long-term auditory-motor therapy program.

Our analysis is based on the emergence of organizational routines while taking into consideration naturalistic decision making approach. From the managerial perspective, our results demonstrate that the implementation of this technology decrease individual expertise. This is done through the degradation of individual situation awareness and coordination between team members. We established recommendations for an efficient technology implementation by restricted teams. Our methodology consists of mixing heterogenic sources: interviews, observations, videos, debriefing with auto-confrontation… this opens the door for new analysis strategies till now used mainly in psychology. Finally, our theoretical contributions reinforced the naturalistic approach while insisting on the important role of a team leader and the role of individual expertise in the development of new functional organizational routines

Full textAbstract:
This dissertation examines interaction in a hybrid educational and clinical medical context, specifically how students and tutors negotiate and display expertise and uncertainty in problem-based learning (PBL) tutorials in the final years of an undergraduate medical curriculum. I take a broad view of expertise and uncertainty, one which includes scientific knowledge, evidence-based explanations, warrants for uncertainty, personal experience and communicative performance. Taking a discourse analytic approach, I analyse what constitutes expertise in this tutorial setting and how it is negotiated and displayed through the participating students’ and tutors’ interactional dynamics. I examine the nature of the various tutorial activities, the educational and clinical context, and how factors associated with the ethos and approaches of both PBL and traditional clinical curricula influence the display and negotiation of expertise and uncertainty. The data were collected during 2008 in two teaching hospitals in Hong Kong. Participants were selected by convenience sampling. Eight tutorials were video or audio recorded, and the interactions were transcribed. The discourse analytical approach (activity analysis, Sarangi 2010a) is based on the notions of activity types (Levinson, 1992[1979]) and discourse types (Sarangi, 2000) as well as notions of participant structure, roles, frames, and alignment. The analysis is conducted in three stages. First, the structural mapping indicates that the tutorials were composed of three main elements – presenting a patient history, presenting clinical reasoning, and presentation of the findings of the physical examination and that these were recursive. Second, the interactional mapping shows that the dominant participants were the presenter of the patient history and the tutor, and that the main discursive device is questioning. Third, the thematic mapping shows that implicit throughout the interaction is the display of expertise through role performance, and the hybrid clinical and educational frames associated with these roles. Role, frame and activity characteristics interact to contribute to a complex setting within which participants could display degrees of expertise and uncertainty.

Full textAbstract:
This dissertation consists of two largely stand-alone chapters. The first chapter presents a goal-activation theory of the antecedents of advice taking. I propose that three separate categories of goals - decision quality, social standing, and emotional well-being - influence receptivity to advice. Decision quality goals increase striving toward a good outcome in the decision for which the advice was given. Social standing goals focus attention on the social effects of the act of taking or rejecting the advice. Emotional well-being goals are related to establishing or maintaining a desired affective state. Each of these goals can be activated by attributes of the situation, advice, advisee, and advisor. Because they increase striving toward different ends, the goals direct attention to disparate advice-related cues and affect the evaluation of those cues. This results in different responses to advice. At the current time, nearly all research on advice taking has addressed decision quality goals and related cues. By presenting this theory, I hope to increase interest in a wider set of antecedents of advice taking. The second chapter reports a series of studies testing hypotheses derived from the theory presented in the first chapter. Specifically, I contrast the effects of an advisor's relative expertise to effects of the advisor's relative hierarchical position on advice taking. I hypothesize that the effects of expertise are driven by decision quality goals, while the effects of relative hierarchical position relate to social standing goals. I further hypothesize that advisees' conceptions of appropriate leader-follower relations (specifically, follower co-production role orientation; Carsten & Uhl-Bien, 2012) activate social standing goals, but not decision quality goals. Lastly, I propose that outcome accountability increases attention to decision quality goals and reduces attention to social standing goals.

The subject chosen to develop this thesis project on is developing an algorithm or methodology for system selection. The specific problem studied involves a procedure to determine anion computer system alternative is the best choice for a given user situation.The general problem to be addressed is the need for one to choose computing hardware, software, systems, or services in a -Logical approach from a user perspective, considering cost, performance and human factors. Most existing methods consider only cost and performance factors, combining these factors in ad hoc, subjective fashions to react: a selection decision. By not considering factors treat measure effectiveness and functionality of computer services for a user, existing methods ignore some of the most important measures of value to the user.In this work, a systematic and comprehensive approach to computer system selection has been developed. Also developed were methods for selecting and organizing various criteria.Also ways to assess the importance and value of different service attributes to a end-user are discussed.Finally, the feasibility of a systematic approach to computer system selection has been proven by establishing a general methodology and by proving it through a demonstration of a specific application.

Full textAbstract:
The European General Data Protection Regulation (GDPR) will soon come into force, it is a regulation which spells out increased compliance demands for data protection by design. Failure to comply can lead to huge financial penalties, something IT companies controlling and processing personal data should not ignore. As the one-year countdown begins, studies have revealed under-preparedness of organizations affected by the GDPR. None of the studies so far has offered an integrated overview of the barriers faced by IT companies to embrace data protection by design. This study aims to help fill this gap and to investigate. A study based on expert’s knowledge has been carried out, using an integrated approach. Five experts from advocacy, legal and IT industry were interviewed, aiming to answer the following research question: “What are the barriers for IT companies to embrace data protection by design and how should these barriers be overcome?” An integrated overview of the barriers will then be presented, which includes the managerial, engineering and legal obstacles. The study goes on to present pathways to embrace data protection by design. A key contribution to this study is that managerial, legal and engineering barriers have shown to be directly interconnected and influence on each other. As such a much broader view must be undertaken to fully understand the different barriers that face IT companies in embracing data protection by design.

Full textAbstract:
L’objectif de ce travail était d’identifier certains des déterminants perceptivo-cognitfs et/ou perceptivo-moteurs de l’expertise dans les sports de balle dans des environnements virtuels. Des joueurs de tennis et de basket avec différents niveaux d’expertise ont été testés au cours d’une première partie expérimentale comportant deux études de jugements perceptivo-cognitifs et une étude de poursuite visuo-manuelle. Les résultats n’ont pas montré de différence liée à l’expertise dans les tâches de jugements perceptivo-cognitifs, mais seulement dans la tâche de poursuite visuo-manuelle. Ce résultat questionne sur le rôle des représentations (ou des modèles internes) dans le développement de l’expertise et met en avant l’importance des régulations perceptivo-motrices pour discriminer l’expertise. Sur la base de ces résultats et afin d’explorer davantage l’expertise dans le registre perceptivo-moteur, une seconde partie expérimentale comportant trois expérimentations a été réalisée en utilisant des tâches de poursuite visuo-manuelle. Les résultats révèlent des capacités d’adaptation et de régulation du mouvement supérieures des experts particulièrement dans les situations où les trajectoires sont peu prévisibles. Les résultats obtenus au cours de cette thèse permettent en définitive de mettre en évidence que les tâches de poursuite visuo-manuelle aussi schématiques soient-elles, sont discriminantes de l’expertise en sport de balle. Ils soulignent des perspectives de développement des environnements virtuels pour tester et entraîner les experts dans le registre perceptivo-moteurThe aim of this thesis is to identify the perceptual-cognitive and perceptual-motor determinants of expertise in ball sports in virtual environments. Tennis and basketball players with different levels of expertise were tested. To this purpose, the first experimental part contained two perceptual judgment studies and a visuomotor tracking study. Results did not show any difference between experts and non-experts in perceptual judgment tasks, but only in the visuomotor tracking task. Results raise some questions about the role of representations (or internal models) in the development of expertise. Results highlight the importance of perceptual-motor regulations to discriminate expertise. In order to explore more deeply the perceptual-motor process of expertise, a second experimental part involving three experiments was performed using visuomotor tracking tasks. Results reveal higher adaptation and regulation abilities of experts, particularly in the most constraint periods of tracking. This finding highlights that the visuomotor tracking tasks can discriminate expertise in ball sports. The present thesis reveals the potential of virtual environments to test and train perceptual-motor processes of experts

Full textAbstract:
L'hypertension est connue pour être l'une des principales causes de maladies cardiaques et d'accidents vasculaires cérébraux, tuant environ 7,5 millions de personnes dans le monde chaque année, principalement en raison de son diagnostic tardif.Afin de confirmer le diagnostic d'hypertension, il est nécessaire de collecter des mesures médicales répétées. Une solution consiste à exploiter ces mesures et à les intégrer dans les dossiers électroniques de santé par des algorithmes d'apprentissage automatique.Dans ce travail, nous nous sommes concentrés sur les méthodes d'ensemble qui combinent plusieurs algorithmes d'apprentissage automatique pour la classification. Ces modèles ont été largement utilisés pour améliorer les performances de classification d'un seul classificateur. Pour cela, des méthodes telles que Bagging et Boosting sont utilisées. Ces méthodes utilisent principalement le vote majoritaire ou pondéré pour intégrer les résultats des classificateurs. Cependant, un inconvénient majeur de ces approches est leur opacité, car elles ne fournissent pas d'explication des résultats et ne permettent pas une intégration préalable des connaissances. Comme nous utilisons l'apprentissage automatique pour les soins de santé, l'explication des résultats de classification et la possibilité d'introduire des connaissances de domaine et cliniques dans le modèle appris deviennent une nécessité.Afin de pallier ces faiblesses, nous introduisons une nouvelle méthode d'ensemble basée sur l'argumentation multiagents.L'intégration de l'argumentation et de l'apprentissage automatique s'est avérée fructueuse et l'utilisation de l'argumentation est un moyen pertinent de combiner les classificateurs. En effet, l'argumentation peut imiter le processus décisionnel humain pour réaliser la résolution des conflits.Notre idée est d'extraire automatiquement les arguments des modèles ML et de les combiner à l'aide de l'argumentation. Cela permet d'exploiter les connaissances internes de chaque classifieur, de fournir une explication des décisions et de faciliter l'intégration des connaissances du domaine.Dans cette thèse, les objectifs étaient multiples. Du point de vue de l'application médicale, l'objectif était de prédire le traitement de l'hypertension et la date de la prochaine visite chez le médecin. D'un point de vue scientifique, l'objectif était d'ajouter de la transparence à la méthode d'ensemble et d'injecter des connaissances du domaine.Les contributions de la thèse sont diverses:-Explication des prédictions;-Intégration des connaissances internes de classification;-Injection des connaissances du domaine;-Amélioration de la précision des prédictions.Les résultats démontrent que notre méthode fournit efficacement des explications et de la transparence des prédictions des méthodes d'ensemble et est capable d'intégrer le domaine et les connaissances cliniques dans le système. De plus, il améliore les performances des algorithmes d'apprentissage automatique existantsHypertension is known to be one of the leading causes of heart disease and stroke, killing around 7.5 million people worldwide every year, mostly because of its late diagnosis.In order to confirm the diagnosis of Hypertension, it is necessary to collect repeated medical measurements. One solution is to exploit these measurements and integrate them into Electronic Health Records by Machine Learning algorithms.In this work, we focused on ensemble learning methods that combine several machine learning algorithms for classification. These models have been widely used to improve classification performance of a single classifier. For that purpose, methods such as Bagging and Boosting are used. These methods mainly use majority or weighted voting to integrate the results of the classifiers. However, one major drawback of these approaches is their opacity, as they do not provide results explanation and they do not allow prior knowledge integration. As we use machine learning for healthcare, the explanation of classification results and the ability to introduce domain and clinical knowledge inside the learned model become a necessity.In order to overcome theses weaknesses, we introduce a new ensemble method based on multiagent argumentation.The integration of argumentation and machine learning has been proven to be fruitful and the use of argumentation is a relevant way for combining the classifiers. Indeed, argumentation can imitate human decision-making process to realize resolution of the conflicts.Our idea is to automatically extract the arguments from ML models and combine them using argumentation. This allows to exploit the internal knowledge of each classifier, to provide an explanation for the decisions and to facilitate integration of domain and clinical knowledge.In this thesis, objectives were multiple. From the medical application point of view, the goal was to predict the treatment of Hypertension and the date of the next doctor visit. From the scientific point of view, the objective was to add transparency to ensemble method and to inject domain and clinical knowledge.The contributions of the thesis are various:-Explaining predictions;-Integrating internal classification knowledge;-Injecting domain and clinical knowledge;-Improving predictions accuracy.The results demonstrate that our method effectively provides explanations and transparency of the ensemble methods predictions and is able to integrate domain and clinical knowledge into the system. Moreover, it improves the performance of existing machine learning algorithms

Full textAbstract:
Research based on translation expertise, which is also sometimes referred to as translation competence, has been a growing area of investigation in translation studies. These studies have not only focused on how translation expertise may be conceptualised and defined, but also on how this expertise is acquired and developed by translators. One of the key observations that arise from an overview of current research in the field of translation expertise is the prevalence of process-oriented methodologies in the field, with product-oriented methodologies used comparatively infrequently. This study is based on the assumption that product-oriented methodologies, and specifically the corpus-based approach, may provide new insights into translation expertise. The study therefore sets out to address the lack of comprehensive and systematic corpus-based analyses of translation expertise. One of the foremost concerns of corpus-based translation studies has been the investigation of what is known as the features of translated language which are often categorised as: explicitation, simplification, normalisation and levelling-out. The main objective of this study is to investigate the hypothesis that the features of translated language can be taken as an index of translation expertise. The hypothesis is founded on the premise that if the features of translated language are considered to be the textual traces of translation strategies, then the different translation strategies associated with different levels of translation expertise will be reflected in different frequencies and distributions of these features of translated language in the work of experienced and inexperienced translators. The study therefore aimed to determine if there are significant differences in the frequency and distribution of the features of translated language in the work of experienced and inexperienced translators. As background to this main research question, the study also investigated a secondary hypothesis in which translated language demonstrates unique features that are the consequence of various aspects of the translation process. A custom-built comparable English corpus was used for the study, comprising three subcorpora: translations by experienced translators, translations by inexperienced translators, and non-translations. A selection of linguistic operationalization’s was chosen for each of the four features of translated language. The differences in the frequency and distribution of these linguistic operationalization’s in the three sub corpora were analysed by means of parametric or non-parametric ANOVA. The findings of the study provide some support for both hypotheses. In terms of the translation expertise hypothesis, some of the features of translated language demonstrate significantly different frequencies in the work of experienced translators compared to the work of inexperienced translators. It was found that experienced translators are less explicit in terms of: formal completeness, simplify less frequently because they use a more varied vocabulary, use longer sentences and have a lower readability index score on their translations, and use contractions more frequently, which signals that they normalise less than inexperienced translators. However, experienced translators also use neologisms and loanwords less frequently than inexperienced translators, which is suggestive of normalisation occurring more often in the work of experienced translators when it comes to lexical creativity. These linguistic differences are taken as indicative of the different translation strategies used by the two groups of translators. It is believed that the differences are primarily caused by variations in experienced and inexperienced translators‟ sensitivity to translation norms, their awareness of written language conventions, their language competence (which involves syntactic, morphological and vocabulary knowledge), and their sensitivity to register.
Furthermore, it was also found that there are indeed significant differences between translated and non-translated language, which also provides support for the second hypothesis investigated in this study. Translators explicitate more frequently than non-translators in terms of formal completeness, tend to have a less extensive vocabulary, tend to raise the overall formality of their translations, and produce texts that are less creative and more conformist than non-translators‟ texts. However, statistical support is lacking for the hypothesis that translators explicitate more at the propositional level than original text producers do, as well as for the hypothesis that translators are inclined to use a more neutral middle register.MA (Language Practice), North-West University, Vaal Triangle Campus, 2013

Full textAbstract:
This thesis focuses on defining a set of design strategies to develop and assess video games that foster physical activity, commonly referred to as exergames. Regular physical activity is essential for a good development of children and exergames have the potential to be used as an adherent and fun tool. This should result in more healthy children and compensate for the current lack of physical activity due to sedentary behaviors.
This thesis focuses both on quantity as well as quality of physical activity. Concerning quantity, we focus on aerobic activity, while quality refers to richness and diversity of movement within conditional and coordinative capacities.
This thesis is a first step to design exergames as public health tools by bridging the notions of playability and efficacy of exergames. We define an interdisciplinary protocol to design multiplayer exergames in collaboration with physical activity experts. A parameter, the Interaction Tempo, and evaluation methods to control the amount of physical activity are presented and validated. We provide strategies to achieve the aforementioned quality of physical activity in exergames and a robust evaluation method to assess it during a play session. We finally explore the influence and limitations that the body attitude can have on the intensity and affective state.Aquesta tesi se centra en la definició d'un conjunt d'estratègies de disseny per a desenvolupar i avaluar els videojocs que fomenten l'activitat física, comunament coneguts com a exergames. L'activitat física regular és essencial per a un bon desenvolupament dels nens i els exergames tenen el potencial de ser utilitzats com una eina divertida i que fomenti l'adhesió al programa d'exercici. Això ha de resultar en nens més sans i compensar l'actual falta d'activitat física a causa dels comportaments sedentaris. Aquesta tesi es focalitza tant en la quantitat com en la qualitat de l'activitat física. Per al que fa a la quantitat, ens centrem en l'activitat aeròbica, mentre que la qualitat es refereix a la riquesa i diversitat del moviment dins de les capacitats condicionals i coordinatives. Aquesta tesi és un primer pas per dissenyar exergames com a eines de salut pública a través de crear una relació entre les nocions de jugabilitat i l'eficàcia dels exergames. Definim un protocol interdisciplinari per a dissenyar exergames multi jugador en col•laboració amb experts en activitat física. Es presenta i valida el Tempo d'Interacció, un paràmetre per a controlar la quantitat d'activitat física, com també mètodes d'avaluació d'aquesta. Proporcionem estratègies per aconseguir la qualitat, abans esmentada, de l'activitat física en exergames i un mètode d'avaluació sòlida per a avaluar-la durant una sessió de joc. Finalment explorem la influència i limitacions que l'actitud del cos pot tenir sobre la intensitat i estat afectiu.

Inference under uncertainty plays a crucial role in expert system and receives growing attention from artificial intelligence experts, statisticians, and psychologists. In searching for new satisfactory ways to model inference under uncertainty, it will be necessary to combine the efforts of researchers from different areas. It is expected that with deep insight into this crucial problem, it will not only have enormous impact on development of AI and expert system, but also bring classical areas like statistics into a new stage. This research paper gives a precise synopsis of present work in the field and explores the mechanics of statistical inference to a new depth by combining efforts of computer scientists, statisticians, and psychologists. One important part of the paper is the comparison of different paradigms, including the difference between statistical and logical views. Special attentions, which need to be paid when combining various methods, are considered in the paper. Also, some examples and counterexamples will be given to illustrate the availability of individual model which describes human behavior. Finally, a new framework to deal with uncertainty is proposed, and future trends of uncertainty management are projected.Department of Mathematical Sciences

Full textAbstract:
The penetration of smart pocket-size devices that provide constant Internet connectivity, such as mobile phones, has significantly changed the way people obtain, view and share information. Content provision is not anymore a prerogative to professionals; individuals are not solely customers, but also act as content generators and distributors. This shift in social behavior requires changes in the way information is delivered to target audiences in an efficient, interest-based and location-aware manner. This thesis explores a solution for opportunistic content distribution in a content-centric network that primarily targets content dissemination among mobile users in urban areas. The term ’opportunistic’ here refers to a concept which rejects the assumption of always-connected user devices and instead allows nodes to leverage sporadic contacts which occur when two neighbors come into direct radio communication range. Such communication mode allows data exchanges to occur in areas with little or no infrastructure; moreover, it is a potential solution for offloading the increasing traffic volumes observed by mobile operators. The contributions of this thesis lie in three areas. We first outline a general architecture and design for opportunistic content-centric networking. We implement our proposal on the Google Android platform, and provide application scenarios which illustrate the potential of mobile peer-to-peer communication. Our tests however show that energy consumption turns out to be a major issue for opportunistic networks. Therefore, our second effort is in the area of energy-efficiency. We propose a dual-radio architecture for opportunistic communication, and evaluate it through extensive simulations on realistic human mobility traces. Our final study lies in the area of content dissemination when nodes in the network act altruistically and are willing to solicit data on behalf of other participants. We propose a number of relaying and caching strategies, and evaluate them through simulations in environments that exhibit different churn levels.QC 20120806

Full textAbstract:
Here, we investigated the effects of modulation of the GABAergic system using a targeted neuropharmacological, 1H/13C NMR spectroscopy and metabolomic approach in Guinea pig cortical brain slices. The effects of exogenous GABA, agonists, antagonists and allosteric modulators at GABAA receptors were described and classified on the basis of metabolic activity; this corresponded to receptor location rather than pharmacology. The effects of agonists and antagonists at the GABAB receptor were described and classified into inhibitory and excitatory components, consistent with context dependent outcomes of receptor activity. Metabolic evidence for GABAC mediated activity in the cerebral cortex was identified for the first time indicating a strong role for this receptor in the control of neuronal activity. Inhibition of GABA uptake was examined using inhibitors of these transporters. The major effect of individual transporter subtype blockade was increased synaptic inhibition. The paradoxical activity of the GABA-transaminase inhibitor vigabatrin was resolved, with a direct demonstration of a single inhibitory mechanism mediated via this drug, via a mechanism also induced by antagonists at the GABAC receptor. These data were then integrated using multivariate statistics to identify 5 subclasses of activity which corresponded to receptor location (e.g. synaptic or extrasynaptic) rather than receptor pharmacology. This represents a novel and powerful new approach to the study of brain metabolism and the GABAergic system.

In the context of a speech recognizer application, we use low-power analog approaches for the signal conditioning and basic auditory feature extraction, while using a neuromorphic IC for building a dendritic classifier that can be used as a low-power word spotter. In doing so, this work also aspires to posit the significance of dendrites in neural computation.
