Darnell, Doyanne A. « Investigating the Utility of the Film War Zone as a Component of a Street Harassment Prevention Program ». Digital Archive @ GSU, 2006. http://digitalarchive.gsu.edu/psych_theses/29.
Texte intégralRésumé :
Street harassment, the sexual harassment by strangers in public places, is a common experience shared by many women and has been linked with other forms of sexual victimization. The negative impact of street harassment, such as fear and behavior to avoid being harassed, points to the need for preventing the behavior. This study sought to determine whether the documentary-style film War Zone may be effective in impacting men’s attitudes toward street harassment, and whether the effectiveness of the film would depend on men’s hostility toward women and level of peer acceptance for street harassment. Findings do not support the effectiveness of War Zone as a component of street harassment prevention. However, the data does suggest that endorsement of hostile attitudes toward women predicts a lack of empathy, and that endorsement of hostile attitudes toward women, a lack of empathy, and peer acceptance of street harassment predict acceptance of street harassment.

Ruwhiu, Diane, et n/a. « The sleeping Taniwha : exploring the practical utility of kaupapa Maori in firm performance ». University of Otago. Department of Management, 2009. http://adt.otago.ac.nz./public/adt-NZDU20090810.161823.
Texte intégralRésumé :
This thesis takes the position that firm performance is derived from the value embodied by combinations of distinct socio-cultural resources and capabilities. In particular, this thesis explores practice in the context of Maori business to understand the mutual influences between economic exchange and social-cultural structures in terms of achieving improved firm performance. I begin by suggesting that much of the knowledge development and community practice in organisational analysis is subsumed within a Kuhnian conventionalism, which is not useful to gaining a deeper understanding of firm performance. I argue that what is required is an approach that emphasises the contextual development of society and organisation (embodied by social and cultural relations).
This brings to the fore the pragmatist epistemology of practical knowledge, an approach to research and analysis of organisations that is at the heart of this research. Practical knowledge connects to the pragmatic orientation of Indigenous logics in this instance kaupapa Maori, which draws us to a perspective of knowledge that is experiential, contextual, diverse and inclusive. The effectiveness of a practical knowledge perspective by means of its pragmatic epistemology allows us to understand Maori businesses operating within a distinctive frame of socio-economic rationality providing a broader utility leading to culturally constituted forms of practice. It was through this lens that I engaged with the proposition regarding firm performance prompting us to look at the field of leadership (habitus), exchange (inter-capital exchange) and relationships (field) in particular.
A major emphasis was a search for an appropriate method that would provide an avenue of authentic engagement with the cultural context embodied by kaupapa Maori. In terms of empirical investigation this thesis advances the utility of narrative as an expository technique and interpretive device that accords full recognition of Maori socio-cultural systems of relationships, historic circumstances and current practices. Conducted over three years (December 2004 and June 2006), the fieldwork component involved multiple strands of narrative in the form of dialogue, stories,metaphors, documentation and experiences of myself, other individuals and Maori economic development hui, or gathering.
A key finding of this thesis is that kaupapa Maori as expressed through business practice offers a practical utility in relation to the capability of and potential outcomes for improved firm performance. I argue that there are unique characteristics of Maori business practice, which are grounded in the epistemological stance of kaupapa Maori in combination with Western philosophies and techniques of organisation that contribute to the performance of Maori businesses. In addition, I argue that it offers a view of the organisation as something beyond a disembodied system of market exchange and recognises the embeddedness of social processes in each culture will bring specific cultural nuances to the formulation of what constitutes organisational success. Finally, I suggest that kaupapa Maori research, grounded by the epistemological and ontological assumptions of an Indigenous paradigm provides opportunities for gaining greater insight into the dynamics of organisation and management research.

Texte intégralRésumé :
A avaliação de projetos e sua viabilidade econômico-financeira tradicionalmente são calculadas utilizando o método consagrado do fluxo de caixa descontado. Entretanto, o fato de um projeto ser financeiramente viável não significa necessariamente que ele reflita a preferência dos stakeholders. Além disso, a metodologia do fluxo de caixa descontado não consegue avaliar de forma eficiente projetos que possuem aspectos qualitativos relevantes. Por isso, é necessária uma metodologia que seja capaz de captar esses aspectos, como a Análise Multicritério (AMC). Dessa forma, o trabalho tem como objetivo mostrar o processo de escolha e priorização de projetos por um Comitê de Investimentos hipotético em uma distribuidora de energia elétrica através da utilização de um método de analise multicritério, o MAPM (Mutiattribute Preference Model), e como esses aspectos quantitativos e qualitativos podem ser relevantes para tomada de decisão. Foram atribuídos pesos a objetivos (dois) e critérios (sete), para a geração da função utilidade de cada um dos tomadores de decisão e analisou-se o comportamento e a coerência das decisões produzidas pelo calculo dos scores de cada projeto, os quais apresentaram consistência. Adicionalmente, foi realizada comparação dos resultados obtidos com aqueles gerados através da utilização de outro método de analise multicritério, o AHP (Analytic Hierarchy Process), e observou-se similaridade nos mesmos. Esses resultados, especialmente quando aplicados num contexto real de decisão numa distribuidora de energia elétrica, demonstra que a análise multicritério pode ser uma ferramenta relevante de avaliação e priorização de projetos.The evaluation of a project and its economic and financial viability are frequently calculated using the discounted cash flow method. However, the fact that a project is financially feasible doesn´t necessarily means that it reflects the preferences of the stakeholders. Besides this, the discounted cash flow method isn´t capable of valuing projects with relevant qualitative aspects. In order to try to capture these significant aspects, an appraisal methodology such as Multi-criteria analysis (MCA) is required. This article describes a project selection process made by an Investment Committee (IC)in a power utility firm using a multi-criteria analysis method, the MAPM (Mutiattribute Preference Model), and how these quantitative and qualitative criteria can play a relevant role for the project selection decision. We study the decision process by first asking the IC members to attribute weights for both objectives (two) and criteria (seven), in order to access the utility function of each IC member and then analyzing the behavior and consistency of the decisions produced through calculation of the score of each project. Results indicate that there is consistency between the strategy defined by the firm and the project selection process. Additionally, the results obtained with the MAPM approach were compared with these obtained using another MCA methodology: the AHP (Analytic Hierarchy Process), which yields similar results. The results also show that the application of multi-criteria analysis in a real context of a power utility firm can play a relevant role on capital investment valuation and decision tacking process.

Steensma, Ronald. « Do Acquisitions Generate Abnormal Returns ? Evidence from the Deregulated Electric Utility Industry ». Thesis, Uppsala universitet, Företagsekonomiska institutionen, 2018. http://urn.kb.se/resolve?urn=urn:nbn:se:uu:diva-357790.
Texte intégralRésumé :
From 1992 onwards, the market for corporate control has been changing as a consequence of deregulation in the North American and West European electric utility industry. Motivated by the lack of consensus on the value creation of acquisitions in the deregulated electric utility industry, this study is conducted. Based on a three and eleven-day event window, cumulative abnormal returns (CARs) of 714 acquisition announcements between 1997 and 2017 stemming from North American and West European acquirers, it is found that acquisitions generate on average an insignificant CAR of 0.2%. West European bidders generate a significant return of 0.94% which outperforms the average CAR of -0.02% stemming from North American bidders. For the aggregate sample, it is found that geographic diversification strategies do not outperform each other and that industry-focussed deals outperform industry-diversified deals. North American managers should avoid cross-border deals within the North American region because these deals destruct shareholder value. West European managers should engage in geographic or industry-focussed deals because it is shown the stock market believes that these type of acquisitions generate synergies.

Pittorino, Leonardo Andres. « The relationship between culture, commitment and performance in a South African electricity utility ». Thesis, Rhodes University, 2009. http://hdl.handle.net/10962/d1003878.
Texte intégralRésumé :
The Electricity Distribution Industry (EDI) in South Africa is in the process of restructuring into six Regional Electricity Distributors (REDs). This would entail the merging of the national electricity utility, Eskom Distribution with municipalities to consolidate skills and to improve on efficiencies. This integration would involve the assimilation of not only physical assets but also various organisational cultures into a separate organisation responsible for supplying electricity services within its designated geographical area. A separate challenge facing Eskom is an intensive capital expansion program to increase generation capacity which will require a committed workforce to execute. Organisational culture has been regarded as leading to greater productivity and generating commitment to the values and philosophies of the organisation. The purpose of the research was to determine whether there was a significant relationship between the organisational culture, organisational commitment and employee performance in Eskom Southern Region. In order to achieve this purpose a survey was undertaken (N=83) which measured perceptions regarding the existing organisational culture, preferred organisational culture as well as organisational commitment. Performance rating scores were linked to each respondent and were obtained from the performance management process of Eskom Southern Region. The main findings of this research can be summarised as follows: • The dominant existing organisational culture in Eskom Southern Region is the power culture, while the dominant preferred organisational culture is the achievement culture. • There is a significant organisational culture gap between the existing and the preferred organisational culture in Eskom Southern Region. • The dominant organisational commitment within Eskom Southern Region is affective commitment together with normative commitment. • The findings related to the employee performance include: o A slight but significant negative relationship was measured between the existing achievement culture and employee performance. o No significant relationships were measured between the preferred cultures and employee performance. o No significant relationships were measured between the organisational commitment scales and employee performance. • The findings pertaining to the relationship between organisational culture and organisational commitment can be stated as follows: o A significant positive linear relationship between the existing achievement culture and affective commitment was measured. A strong, significant negative linear relationship between the existing power culture and the affective commitment was also measured. o No significant relationships were measured between the preferred organisational cultures and organisational commitment. o The organisational culture gap has a significant effect on the organisational commitment of employees. • The findings pertaining to the relationship between the biographical variables and the organisational culture, organisational commitment and employee performance can be stated as follows: o There exists a strong significant relationship between the years of service and the existing organisational culture scales. o No significant relationships exist between the preferred organisational culture scales and any of the biographical variables. There was a common agreement across all respondents on the preferred organisational culture. o A significant relationship was found between organisational commitment and the number of people supervised. o A slight but significant positive linear relationship between the age of respondents and employee performance ratings was measured. It can therefore be concluded that the type of organisational culture has a significant impact on the level of affective commitment of the employees within Eskom Southern Region. No significant positive relationship was found between organisational commitment and organisational performance in Eskom Southern Region.

Dorenlor, Julie. « Contribution à l’étude du comportement en corrosion et des évolutions microstructurales d’alliages Ni-Co : application au cas d’un alliage Ni-20Co utilisé dans l’aéronautique ». Thesis, Normandie, 2021. http://www.theses.fr/2021NORMC207.
Texte intégralRésumé :
Les alliages Ni-Co sont utilisés dans l’industrie aéronautique comme revêtement de bord d’attaque de pales d’hélicoptères, en raison de leur résistance à la corrosion et à l’usure, leurs propriétés mécanique et magnétiques. Ces alliages binaires forment une solution solide de structure cubique à faces centrées lorsque le taux de cobalt est inférieur à environ 70 %. Les matériaux d’étude Ni, Ni-20Co et Ni-50Co ont été élaborés par fusion avant de subir une déformation par laminage à froid, et un recuit à 850 °C. Ils se caractérisent par une microstructure équiaxe dont la taille de grains est entre 5 et 14 µm, une forte proportion de joints Σ3, un faible état de contraintes et une absence de texture. Le suivi de l’évolution microstructurale au cours du recuit a permis de déterminer les cinétiques de recristallisation et d’identifier la texture Cube comme un facteur limitant. En parallèle, l’alliage industriel électroformé et nanocristallin Ni-20Co a été examiné, et sa taille de grains a été augmentée artificiellement pour correspondre à celle du matériau modèle. Les propriétés en corrosion ont été étudiées dans deux électrolytes (NaCl 30 g/L et H2SO4 0.5 M) pour déterminer l’impact de la composition et des paramètres microstructuraux sur la tenue en corrosion et les mécanismes de passivation. Les courbes de polarisation potentiodynamique montrent le caractère passif des échantillons riches nickel, et révèlent l’influence néfaste du cobalt. Toutefois, une composition analogue à celle de l’alliage industriel ne dégrade pas significativement les performances en corrosion. Une forte densité de joints de grains, une fraction importante de joints de macle, ou bien une texture (111), sont identifiés comme des paramètres microstructuraux bénéfiques à la résistance en corrosion. La susceptibilité à la piqûration en NaCl est plus marquée pour l’alliage industriel, certainement en lien avec le processus d’électroformage. Les matériaux modèles présentent enfin un comportement actif-passif, typique des alliages de nickel en milieu acide. Des essais de spectroscopie d’impédance électrochimique et de Mott-Schottky ont permis de caractériser les propriétés électrochimiques et semi-conductrices des couche passives. Les résultats semblent converger vers une passivité moins efficace liée à une fraction croissante de cobalt en solution solideNi-Co alloys are used in shielding of leading edge of helicopter blades, due to their good corrosion and wear resistance, mechanical strength and magnetic properties. These binary alloys form a solid solution with a face-centered cubic structure when the cobalt content is less than about 70 %. The study materials Ni, Ni-20Co and Ni-50Co were produced by fusion, before undergoing cold rolling deformation, and annealing at 850 °C. They are characterized by a microstructure with a grain size between 5 and 14 µm, a high fraction of Σ3 boundaries, a low stress state and an absence of texture. The observation of the microstructural evolution during annealing made it possible to determine the kinetics of recrystallization and to identify the Cube texture as a limiting factor. The electroformed, nanocrystalline industrial alloy Ni-20Co was also examined, and its grain size was increased to resemble the model material. Corrosion properties were studied in two electrolytes (30 g/L NaCl and 0.5 M H2SO4) to determine the impact of composition and microstructural parameters on corrosion resistance and passivation mechanisms. Potentiodynamic polarization curves showed the passive character of nickel rich samples, and revealed the detrimental influence of cobalt. However, a composition similar to that of the industrial alloy does not significantly degrade the corrosion performance. A high density of grain boundaries, a large fraction of twin boundaries, or a (111) orientation, are identified as beneficial microstructural parameters for corrosion resistance. A higher susceptibility to pitting, due to Cl- ions, is observed for the industrial alloy, certainly related to the electroforming process. Finally, the model materials exhibit an active-passive behaviour, typical of nickel alloys in an acidic medium. Electrochemical impedance spectroscopy and Mott-Schottky tests enable to characterize the electrochemical and semiconductor properties of the passive layers. The different results seem to converge towards a less efficient passivity linked to an increasing fraction of cobalt in solid solution

Yun, G. C. « The utility of knowledge mapping as an approach to improving corporate and project performance : a case study of a large South Korean consulting firm ». Thesis, University of Salford, 2008. http://usir.salford.ac.uk/2036/.
Texte intégralRésumé :
Knowledge, and its appropriate management, has been increasingly recognised as a critical source of sustainable competitive advantage for companies. Within this context, many companies are developing their strategies and capabilities to effectively create, share and exploit knowledge. This issue has been seen to be particularly important in project-based industries, such as the construction industry. However, in spite of the espoused value of knowledge management approaches they often deliver benefits far below expectations. Research and practice has identified a number of problems and barriers which have depleted the actual benefits of knowledge management in projects and companies. A generic finding is that the major problem is the lack of effective integration of key knowledge management components. Knowledge maps have been promoted as a key solution to bring about this required integrated approach. The knowledge mapping approach has taken root in other sectors (particularly education and manufacturing), but is still at an embryonic state in construction. The starting point for this research is to investigate the potential utility of knowledge mapping as an approach to improving corporate and project performance. First, a concept model for appropriate knowledge mapping within construction project organisations was articulated through a relevant literature review. The model is made up of four key variables: interaction environment, construction actors, construction processes and knowledge transfer technologies. The concept model was tested through a single-holistic case study within a large construction and property consulting practice in South Korea. Data collection was through semistructured interviews and company document review. The primary data was analysed using content analysis and cognitive mapping. The research findings broadly confirmed that knowledge mapping is an effective approach in integrating project resources and technologies for successful knowledge management within the case study firm. The key characteristics of the concept model in practice are identified and illustrated. A contingency approach to knowledge mapping is proposed with appropriate approaches dependent upon the scope of the construction processes and the scope of the construction actors.

Texte intégralRésumé :
Le cablage imprime utilise en electronique de puissance contribue a la creation des perturbations electromagnetiques des convertisseurs statiques. La theorie des lignes peut s'adapter a l'etude du comportement de ces conducteurs imprimes, la determination precise de leurs parametres lineiques est toutefois necessaire. Le principe adopte consiste a substituer aux conducteurs imprimes des faisceaux de conducteurs cylindriques fins paralleles entre eux et dont les parametres lineiques sont connus par des relations analytiques: c'est la methode des fils fins. Cette methode a ete validee en comparant la repartition de courant dans la section d'un conducteur imprime calculee par la methode des elements finis, a celle calculee par la methode des fils fins, dans une bande de frequences s'etendant de 10 khz a 100 mhz. Des verifications experimentales ont egalement confirme cette methode. Enfin, il a ete montre qu'elle permet de determiner precisement les impedances de lignes microruban. L'interet de ce principe reside dans la modelisation globale du comportement electrique des lignes tant en mode differentiel qu'en mode commun. La modelisation d'un cablage imprime est aborde en plusieurs etapes. La premiere etape consiste en un decoupage du cablage imprime en un ensemble de circuits elementaires. L'importance des couplages entre lignes determine fortement les temps de calcul. Aussi, un critere de couplage a ete defini pour quantifier les differentes situations de couplage entre conducteurs, afin de separer le traitement simple et rapide de lignes faiblement couplees, de celui plus long de conducteurs fortement couples. A partir des dimensions des conducteurs et des courants maximaux qui les traversent, il est ainsi possible de determiner l'importance du couplage entre lignes. La seconde etape consiste a modeliser les conducteurs par des multipoles qui sont ensuite identifies a un reseau electrique lineaire. Cette identification permet d'obtenir des modeles compatibles avec un simulateur temporel de type spice et adaptes a la complexite des couplages a representer

ENGLISH ABSTRACT: In South Africa few systematic studies have been done on university-industry partnerships. This research investigated the evolution of the University of Cape Town (UCT) and SASOL partnership involving heterogeneous catalysis. As part of this investigation, I analysed the driving force and sought to determine the motivations and benefits that UCT and SASOL have since accrued as a result of their partnership. I also analysed knowledge transmission or technology transfer processes such as the hiring of graduates, intellectual property etc. In light of all of these I sought to draw lessons that could be learnt from UCT-SASOL partnership for future purpose. I followed four themes or sections in order to situate the study. These were, (a) the socio-economic context (global and knowledge economy, innovation, knowledge society etc.), the changing modes of knowledge production ("Mode 2") and the changing ways of interactions among stakeholders industry, university and government (Triple Helix). The key argument here is that the university industry partnership cannot be seen as an independent development, but is interrelated or partly the consequence of changes in the socio-economic, science, technology and higher education fields, (b) The driving force behind the partnership, (c) motivations, benefits, and (d) knowledge or technology transfer/transmission processes. I used the case study research design. I conducted interviews with the UCT Chemical Engineering Department, UCT Centre for Research and Innovation and SASOL officials. I collected several documents related to the study and also visited the laboratories in which UCT-SASOL partnership research activities were happening. Some of the findings of the study include the following. The partnership demonstrates the significant role of an individual academic, who steered transformation in terms of research activities and culture in the Chemical Engineering Department. The legacy of the individual academic's strong personality and commitment to research is evident and continues to stimulate high levels of research interest and teamwork among staff members which is characteristic of this department. A strong link is maintained between the basic disciplinary "Mode 1" teaching and research on the one hand and the multidisciplinary "Mode 2" applied and strategic research and training on the other: This is evident in the strong emphasis on the solid undergraduate disciplinary education as a basis for a high quality multidisciplinary postgraduate education. All staff members are involved in both teaching and research. A strong link is maintained between academic, research and postgraduate activities: The department utilizes surpluses generated through industrial-oriented research to cross-subsidize the academic and postgraduate activities.
AFRIKAANSE OPSOMMING: Daar is weinig sistemiese studies in Suid-Afrika reeds uitgevoer oor universiteit-industrie samewerking. Hierdie studie ondersoek die ontwikkeling van 'n vennootskap tussen die Universiteit van Kaapstad (UK) en SASOL wat heterogene katalise insluit. Ek analiseer in hierdie studie die dryfkrag van die vennootskap, en probeer die motivering en voordele bepaal wat beide die UK en SASOL toegekom het as deel van hulle vennootskap. Ek analiseer ook die oordrag van kennis of oordrag van tegnologiese prosesse, die aanstelling van graduandi, intellektuele eiendom, ens. Ek probeer op grond hiervan lesse van die UK-SASOL vennootskap uitlig vir toekomstige doeleindes. Ek het vier temas of afdelings gebruik om hierdie studie te vestig. Dit is, (a) die sosio-ekonomiese konteks (globale en kennis ekonomie,innovasie, kennis samelewing ens.), die veranderende modus van kennis produksie ("Modus 2") en die veranderende wyses van interaksie tussen belanghebbendes - industrie, universiteit en regering (Triple Helix). Die sleutel argument hier is dat die universiteitindustrie vennootskap nie gesien kan word as 'n onafhanklike ontwikkeling, maar dat dit verband hou met of deel is van die gevolge van die veranderinge in die sosio-ekonomiese, wetenskap, tegnologie en hoer onderwys arenas; (b) die dryfkrag agter die vennootskap; (c) motivering en voordele; en (d) die oordrag van kennis of tegnologie/oordrag van prosesse. Ek gebruik die gevallestudie metodologie in hierdie studie. Ek het onderhoude gevoer met die UK Chemiese Ingenieurswese Departement, die UK Sentrum vir Navorsing en Innovasie, asook die SASOL betrokkenes. Ek het die projekdokumentasie versamel en het ook die laboratoriums besoek waarin die navorsingsaktiwiteite van die UK-SASOL vennootskap plaas vind. Die bevindinge van hierdie sluit dus die volgende in. Die vennootskap demonstreer die belangrike rol van 'n individuele akademikus wat transformasie bewerkstellig het in terme van navorsingsaktiwiteite en die kultuur in die Chemiese Ingenieurswese Departement. Die nalatenskap van die individuele akademikus se sterk persoonlikheid en toewyding tot navorsing is duidelik en stimuleer steeds hoe vlakke van belangstelling in die navorsing en spanwerk in die departement. Dit is ook een van die kenmerke van hierdie departement. Daar is 'n sterk skakel gehandhaaf tussen die basiese dissiplinere "Modus 1" onderrig en navorsing aan die een kant, en die multidissiplinere "Modus 2" toegepaste en strategiese navorsing en onderrig aan die ander kant. Dit is duidelik in die sterk kleim wat gele word op die stewige voorgraadse dissiplinere onderrig as 'n basis vir 'n hoe kwaliteit multidissiplinere nagraadse onderrig. Alle personeel is betrokke by beide onderrig en navorsing. 'n Sterk skakel is behou tussen akademiese, navorsings- en nagraadse aktiwiteite: die departement gebruik die oorskotte van industrieverwante navorsing om akademiese en nagraadse aktiwiteite te kruissubsideer.

Texte intégralRésumé :
This research was initiated due to declining customer satisfaction indices in the Southern region of Eskom, an electricity utility in South Africa. Given the link between customer satisfaction and purchase intentions, the sustainability of the business is at stake. The validity of the current MaxiCare survey tool is questioned and explored, as is the congruence of management and customers' perceptions regarding the key service quality constructs in the industry. The study's objective was to provide management with a reliable and valid customer satisfaction survey instrument as an alternate to the existing tool and to use the knowledge gained through the research process to recommend improvement strategies aimed at closing specific satisfaction gaps identified. The research was performed in two stages; firstly, semistructured interviews with customers and management to gain an understanding of the most important satisfaction dimensions. These influenced the design of a survey instrument based largely on the SERVPERF tool with the inclusion of importance ratings per item in the second stage. The quantitative survey results were used to assess the reliability and validity of the research and to suggest areas for future work. The results show that communication, quality of supply, assurance and price are uppermost in the consumer's mind. Tangibles are not significant and the inclusion of empathy is inconclusive. Management and customer perceptions at a macro level are closely aligned, however the two populations are not in agreement as to the underlying micro considerations. Similarly, the MaxiCare instrument is found to be valid as a macro indicator but lacks sufficient detail to be useful as a strategic tool and needs to be supplemented with additional sources of market information. The survey instrument used in the second phase is both descriptive and reliable but the number of factors it measures, the mix of items and the inclusion of the 'importance' dimension need further refinement to improve its validity. Future revisions of the tool will provide management with specific information that allows them to focus improvement strategies on disgruntled customers and their key service issues.

Texte intégralRésumé :
La thrombose survenant après implantation d’un biomatériau en contact avec le sang est un problème majeur. L’utilisation de polymères comme supports pour les greffes vasculaires ou comme matériaux de recouvrement pour les endoprothèses vasculaires (stent) peut améliorer leur hémocompatibilité. C’est dans ce contexte que s’insère l’objectif global de cette thèse quia porté sur l’étude de la biocompatibilité de polyuréthanes, appelés D-PHI (Dégradable Polar/Hydrophobic/Ionic). Pour cette étude, 2 formulations ont été développées, la formule originale appelé O-D-PHI et la formulation HHHI (High Hydrophobic, High Ionic). Elles sont constituées des mêmes monomères dont les ratios molaires varient, permettant ainsi de moduler les caractères polaires, ioniques et hydrophobes du matériau. L’influence de la chimie intrinsèque de ces matériaux sur l’adsorption et la disponibilité de séquences spécifiques de protéines plasmatiques (fibronectine et immunoglobuline G) ainsi sur l’activation des monocytes a été étudiée. Dans l’optique de recouvrement de stents, des films minces micrométrique de polyuréthanes ont été générés à la surface de cobalt chrome et une caractérisation de surface a été réalisée. L’adsorption et la disponibilité de séquences spécifiques de protéines plasmatiques impliquées dans l’inflammation et la coagulation ont ensuite été évaluées ainsi que la réactivité des cellules du sang. Les résultats ont montré que la formulation et l’épaisseur du film influencent l’adsorption et l’exposition de séquences spécifiques de protéines plasmatiques. En revanche, la réactivité des cellules du sang,l’activation de la coagulation et l’inflammation étaient réduites par la présence de films minces de polyuréthanes, quel que soit l’épaisseur du film et la formulationThrombosis occurring after implantation of a biomaterial in contact with blood is amajor problem. The use of polymers as supports for vascular grafts or as cover materials for stents may improve their hemocompatibility. It is in this context that the overall objective of this thesis is to study the biocompatibility of polyurethanes, called D-PHI (Degradable-Polar /Hydrophobic / Ionic). For this study, 2 formulations were developed, the original formula called O-D-PHI and the formulation HHHI (High Hydrophobic, High Ionic). They consist of the same monomers whose molar ratios vary, thus making it possible to modulate the polar, ionic and hydrophobic characteristics of the material. The influence of the intrinsic chemistry of these materials on the adsorption and availability of specific plasma protein sequences (fibronectin and immunoglobulin G) and in regards to the activation of monocytes has been studied. In order to covering stent, micrometric thin films of polyurethanes were generated at the surface of cobalt chrome and surface characterization was performed. The adsorption and availability of specific plasma protein sequences, involved in inflammation and coagulation, were then evaluated as well as the reactivity of blood cells. The results showed that the formulation and film thickness influence the adsorption and exposure of specific plasma protein sequences. In contrast, blood cell reactivity, coagulation activation, and inflammation were reduced by the presence of thin polyurethane films, regardless of film thickness and formulation

Texte intégralRésumé :
Cette thèse aborde la performance du protocole KNX-RF utilisé dans les applications domotiques en termes de robustesse Radio Fréquences dans un environnement multi-protocoles potentiellement sujet aux interférences. Dans ces travaux, le but est d’évaluer les problématiques d’interférences rencontrées par KNX-RF en utilisant des modèles de simulation qui permettraient d’augmenter à sa fiabilité radio. Ainsi, un premier modèle a été développé sur MATLAB/Simulink et a permis de connaître les performances et les limitations de ce protocole au niveau de la couche physique dans un scénario d’interférence se produisant à l’intérieur d’une box/gateway domotique multi-protocoles. Ces simulations ont été complétées par des essais expérimentaux sur le terrain qui ont permis de vérifier les résultats obtenus. Un deuxième modèle a été développé pour évaluer les mécanismes de la couche MAC, cette fois-ci, grâce au simulateur OMNet++/MiXiM. Ce modèle reprend tous les mécanismes d’accès au canal et d’agilité en fréquence spécifiés par la norme KNX. Un scénario de collisions de trames a été simulé et plusieurs propositions d’améliorations sont discutées dans ce manuscrit. Les modèles développés permettent d’analyser et de prédire en avance de phase le comportement de KNX-RF dans un environnement radio contraignantThis thesis addresses the performance of the KNX-RF protocol used for home automation applications in terms of radiofrequency robustness in a multi-protocol environment that is potentially subject to interferences. In this work, the aim is to assess the interference problems encountered by KNX-RF using simulation models that would increase its RF reliability. Thus, a first model was developed on MATLAB / Simulink and allowed to investigate the performance and limitations of this protocol at its physical layer in an interference scenario occurring inside a multiprotocol home and building automation box/gateway. These simulations were followed by field experimental tests in an indoor environment (house) to verify the results. A second model was developed to evaluate the MAC layer mechanisms of KNX-RF through the discrete event simulator OMNeT ++/Mixim. This model includes all the mechanisms of channel access and frequency agility specified by KNX-RF standard. A frame collision scenario was simulated and several improvement proposals are discussed in this manuscript. The developed models can be used to analyze and predict in advance phase the behavior of KNX-RF in a radio-constrained environment

Texte intégralRésumé :
La presente ricerca prende le mosse dalla risonanza del fashion film nell’attuale panorama mediale e in una parte crescente dei film studies e media studies per condurre un’indagine retrospettiva sulle sue genealogie plurali. Traendo ispirazione dalle aggiornate istanze teoriche e metodologiche promosse dall’archeologia dei media e dall’ampio panorama della cultura visuale, abbiamo focalizzato l’attenzione su ambiti filmici non ancora studiati dalla critica e appartenenti a paesi caratterizzati da importanti tradizioni nella cultura della moda, ovvero l’Italia e la Francia.
Mentre le prospettive dell’archeologia dei media e della cultura visuale sono già entrate nell’orizzonte critico grazie a iniziative scientifiche, convegni e recenti pubblicazioni, il fashion film costituisce un oggetto di studio ancora in larga parte trascurato: le riflessioni che gli sono state dedicate provengono dal contesto anglofono. Di particolare interesse per questa indagine è l’interpretazione del fashion film proposta da Marketa Uhlirova, che ha evidenziato come esso esprima un tale investimento sull’esposizione e sulla spettacolarizzazione della moda in movimento da portare a riconoscervi echi significativi del cinema delle origini (Uhlirova 2013; 2013).
Principale ispirazione metodologica è la recente proposta di ripensamento della storia del cinema secondo i metodi dell’archeologia dei media delineata da Thomas Elsaesser (Elsaesser 2016): seguire tale approccio significa estenderne gli orizzonti, indagando materiali filmici e contesti visivi poco studiati o finora trascurati attraverso uno sguardo “retrospettivo e in prospettiva” che li inserisca nel più ampio panorama delle pratiche mediali e dei contesti di fruizione. È in tale contesto che diviene fondamentale il recupero del concetto di attrazione, che, formulato negli anni ottanta da Tom Gunning (Gunning 1986) – poi ampliato da André Gaudreault (Gaudreault 2004) –, per mettere in valore l’unicità del cinema delle origini, torna a essere di grande importanza per considerare pratiche mediali recenti e passate, focalizzando l’attenzione sulla spettatorialità e sull’esperienza sensibile della visione (Strauven 2006). Sulla scorta di tali riflessioni, la presente indagine si ispira ad altri importanti riferimenti teorico-metodologici, quali la riconsiderazione degli utility films e del cosiddetto useful cinema (Hediger/Vonderau 2009; Acland/Wasson 2011; Cowan 2014; Florin/De Klerk/Vonderau 2016), le tecniche spettatoriali e la storicità della visione (Crary 1990), il rapporto tra la modernità, i dispositivi di visione e la società del consumo (Friedberg 1999).
Facendo tesoro di questo orizzonte di studi, abbiamo circoscritto un corpus filmico, comprendente eterogenee forme dedicate alla presentazione della moda prodotte nei due paesi (cinegiornali, film industriali, film educativi, film pubblicitari per il cinema e per la televisione). Le fonti filmiche sono state reperite grazie a una ricerca condotta nei principali archivi audiovisivi italiani (l’Istituto Luce e il Cinema Nazionale del Cinema d’Impresa) e francesi (Gaumont Pathé Archives e l’Institut National de l’Audiovisuel).
A guidare la presente indagine media archeologica del fashion film è una riflessione sulle modalità con cui i film considerati dimostrano di aver concepito lo schermo su cui le proprie immagini sarebbero state proiettate o trasmesse. L’insistenza sull’aspetto esibizionistico e l’esplicita ricerca di un forte impatto sugli spettatori-consumatori, situati in contesti di visione di norma distratti, porta ad assimilarlo a uno strumento di presentazione diretto, una vera e propria vetrina. Da un lato è il fashion film a rappresentare una vetrina per la moda, trovando in ambienti espositivi urbani una notevole cassa di risonanza, dall’altro un simile approccio si rivela di grande efficacia per indagare le forme filmiche che hanno preceduto il genere odierno nella presentazione della moda. Questa prospettiva metodologica servirà a confrontarsi con un motivo centrale nei film e media studies, come lo schermo, considerandone le configurazioni archeologiche e, allo stesso tempo, con una forma urbana e popolare di avvicinamento delle merci al pubblico di massa, di grande risonanza nell’immaginario culturale e visuale: lo sviluppo delle vetrine, infatti, si è situato nell’epoca delle attrazioni, durante la quale ha sospinto la nascente cultura del consumo e le origini della moda moderna. In questa ricerca, il motivo dello schermo-vetrina diviene una prospettiva di convergenza, dove confluiscono, intersecandosi, modalità rappresentative e spettatoriali che dal passato si riflettono sul presente.
Per tracciare un’archeologia del fashion film in Italia e in Francia abbiamo deciso di orientare l’indagine in virtù della prospettiva teorica e metodologica scelta e, in particolare, di alcune possibili declinazioni del rapporto tra schermo filmico e vetrina espositiva. Tre sono le tipologie di relazioni individuate, che hanno guidato da un lato la suddivisione del corpus filmico e la sua analisi e dall’altro la struttura della tesi. La prima, definita “vetrina-schermo”, riguarda i casi in cui la vetrina, come luogo di esposizione delle merci, diviene schermo: un aspetto che si esprime in una sorta di assorbimento dell’iconografia e delle tecniche espositive a livello cinematografico. La seconda, sintetizzata con il sintagma capovolto di “schermo-vetrina”, pone in risalto aspetti di segno opposto, poiché concerne le forme di intensificazione dell’effetto di vetrina attraverso il raddoppiamento dell’esposizione filmica sul piano formale. La terza, denominata “schermo discorsivo” è mossa da una prospettiva ancora diversa, in quanto considera la dimensione educativa talvolta associata alle presentazioni. Sulla scia di queste categorie si è stabilita la scansione tripartita del presente lavoro, dove ogni sezione è a sua volta suddivisa in tre capitoli. Grazie a questa struttura su più livelli interconnessi, si propone di aprire una serie di scorci su alcune delle declinazioni di ciascuna tipologia, quindi di diverse relazioni stabilite con gli spettatori, facendo emergere la molteplicità delle forme assunte dalle attrazioni e, allo stesso tempo, della moda intesa come sfaccettato fenomeno culturale.

Recently, mining high utility patterns has a huge range of applications such as retail market analysis and stock market prediction. The high utility pattern mining is an important research domain in data mining due to its capable of considering the different utility value and non-binary form quantity of each item. To address the limitation of traditional association rule mining, utility mining was defined. The traditional frequent patterns which are recognized by association rule mining does not reveal the impact factor, other than presence or absence of an item. The problem is that frequent patterns may only contribute a small amount of profit, whereas infrequent patterns may contribute a great deal of profit. Therefore, traditional association rule mining needs to expand its functionality to deal with this kind of task. By considering that each item has its individual price or value, utility patterns mining collects and analyzes data to identify the most contribution of the item. In order to perform high utility pattern mining, Yun et al. proposed the Maximum Utility Growth algorithm (MU-Growth) and Maximum Item Quantity tree (MIQ-Tree) to identify high utility patterns. The MU-Growth algorithm uses the overestimated utilities method and constructs their MIQ-Tree data structure. However, the MIQ-Tree has to be reconstructed by extracting every path of the transaction in the MIQ-Tree which will take long time to complete the mining of the whole tree if they contain lots of transactions. Moreover, the MU-Growth algorithm requires to scan database twice and often generates lots of candidates. To solve those problems, in this thesis, we propose the Inverted-File-High-Utility-Pattern-Tree data structure (IFHUP-Tree) and Inverted-File Pattern Growth algorithm to identify high utility patterns from the IFHUP-Tree without generating candidates. There are two types of relations which are concerned in our algorithm: (1) Transaction-Intersection (2) Non-Intersection. First, we concern the case of Transaction-Intersection, then the case of Non-Intersection. The IFHUP-Tree algorithm avoids the reconstructing procedure and generates the patterns with non-overestimated method to get the actual combination of high utility patterns. Our IFHUP-Tree algorithm requires only one database scan and one data structure to identify actual high utility patterns without generating any candidate. From the performance study, we show that our IFHUP-Tree algorithm is more efficient than MU-Growth algorithm both in real and synthetic datasets.

Texte intégralRésumé :
M.Com. (Business Management)The knowledge that people create, possess and share can easily go unnoticed in organisations that do not put effort in identifying it. Knowledge, among other factors, is what people in organisations use to make decisions that can possibly give organisations a competitive advantage. Knowledge, as with other traditionally recognised resources, is a strategic resource that organisations can use to bring about positive change in business. Knowledge can be tacit or explicit and both types need to be managed strategically. Explicit knowledge tends to be easily accessible if it is stored in places such as databases where people can locate it, however, tacit knowledge can be slightly more challenging to access as it lies in the minds of people. Eskom’s Project Development Department (PDD) has 32 project developers who actively develop projects that the organisation will invest in. These projects include electricity generation stations, transmission lines or even pollution mitigating technologies. The project developers work with various stakeholders in and outside of the organisation to ensure that the projects are aligned with the strategic objectives of the organisation. This study aimed to identify the knowledge that the project developers possess and a knowledge audit was conducted on the project developers. The results show that the project developers possess vast amounts of knowledge, skills and are subject matter experts in various fields. The project developers also communicate with various other departments within Eskom when developing projects. A contributing fact to the varying knowledge and skills that the project developers possess is the different projects that each project developer develops. These projects can take up to three years to develop and this can enable a person to acquire knowledge in a specific field of operation. The majority of the project developers also stated that they preferred one on one physical conversations to acquire and share knowledge. Knowledge is gaining recognition as a strategic resource within organisations and strategic management of the knowledge is necessary as it can provide benefits for people and organisations as a whole.

Texte intégralRésumé :
In the last decade, the importance of Enterprise Risk Management (ERM) is emerging and becoming a critical point of discussion and focus on firms due to high uncertainty environments and the economic and financial crisis. The literature and economic theory relate ERM implementation to an increase in firm value and better firms’ performance. This research objective is to analyze the relationship between ERM implementation and firm value in firms from the Utility sector, which is a sector that is constantly changing and innovating due to climate change strategies, decarbonization goals and consumer preferences. To respond to the research question I build a regression, where the explained variable is Tobin’s Q as a proxy to firm value and the explanatory variable is an ERM Score as proxy to firms ERM implementation level. As control variables, I added accounting variables and corporate governance variables that are generally proposed in the literature and other researches like company size, financial leverage, Return on Assets, sales growth, Board size and independence, and dividends. As a sample, I collected data from 10 firms (2 Portuguese and 8 European) from 2017, 2018, 2019, a total of 30 observations. The result demonstrates that Enterprise Risk Management implementation has no significant impact on firms’ value, at the moment. In other words, the market still does not react and recognizes different levels of ERM implementation as a competitive factor to firm value add. It could result from the fact that Enterprise Risk Management implementation also does not have a significant impact on firms accounting performance, as demonstrated in my robustness check analysis. These results vi i are also influenced by the high level of implementation of Enterprise Risk Management in the firms that constitute the sample.Na última década, a importância de Gestão de Risco Empresarial tem aumentado e vindo a ser um ponto essencial de discussão e foco para as empresas, devido à incerteza e crises económicas e financeiras que estas têm vindo a enfrentar.

O objetivo deste trabalho de investigação é analisar a relação entre a implementação de Gestão de Risco Empresarial e o valor das empresas do setor Utility, um setor em constante mudança e inovação devido às estratégias contra as alterações climáticas, objetivos de descarbonização definidos e preferências dos consumidores. De forma a responder à questão de investigação, realizei uma regressão na qual a variável explicada é o Tobin Q, enquanto o proxy para o valor de empresa, e a variável explicativa é um Score ERM como proxy para o nível de implementação de Gestão de Risco Empresarial das empresas, assumindo como variáveis de controlo diversas variáveis contabilísticas e de corporate governance usadas também na literatura, tais como, dimensão, alavancagem, Return on Assets, crescimento das vendas, dimensão, independência do Conselho Administração e dividendos. Recolhi informação sobre 10 empresas do mesmo setor (2 portuguesas e 8 europeias) relativamente aos anos 2017, 2018 e 2019, um total de 30 observações. Os resultados obtidos demonstram que a implementação de Gestão de Risco Empresarial, neste momento, não tem impacto significativo no valor das empresas. O mercado ainda não reage nem reconhece diferentes níveis de implementação de Gestão de Risco Empresarial como um fator diferenciador para a criação do valor da empresa. Os resultados demonstram ainda que a v implementação de Gestão de Risco Empresarial não tem impacto significativo na performance financeira das empresas. Este resultado é influenciado pelo facto de as empresas analisadas terem um elevado grau de implementação de Gestão de Risco Empresarial.

While the state-run utilities face the trend of internationalization and liberalization, the localization of private enterprises and the diversification of running business have been become the main path toward surviving and developing. This dissertation adopts the method of individual case study and utilizes the subject of “Chinese Petroleum Corporation (CPC)” and “A” technology broker. It is divided into two parts to confer this topic more in depth. One is the key success factor of transformation strategy. Another is the role of the procedure of technology broker processes technical transfer. After analyzing and researching on this subject, we conclude the key success factors of transformation strategy of CPC adopted the diversification of running business in telecommunications industry as the following important items. (1) Corresponding to the policy of the liberalization of local telecommunications marketing. (2) To deal with a situation of the existed strategy of the localization and diversification. (3) Optimizing the profit and development of telecommunications marketing. (4) Using the resource of CPC efficiently. During the procedure of technology broker processes technical transfer, we may split those procedures into two phases as “the decision of strategic importance and plan”, and “execution and judgment”. The result of analysis shows that (1) The technology broker does not play any role during “the decision of strategic importance and plan” as the result of the limitation of purchase law of government. (2) During the phase of “execution and judgment” within technology broker processing technical transfer, the role which the steps of “project execution and control management” play is the most various, nevertheless, “open-bid tender and contract agreement” as well as “performance assessment” is much more simplifier. In addition, at the phase of “execution and judgment” when conducting technical transfer, the role of ”preparation and implementation” is applied most frequently but “education and training” is exercised most lowest. (3) During the phase of “execution and judgment”, the technology broker plays different roles in the fields of “consultation”, “correspondence and coordination”, “proxy”, “experience sharing”, “education and training”, and ”preparation and implementation”.

Title of Thesis：How Does Taiwanese Small-Sized Firm Utilize Its Limited Resource to Develop Technology and Marketing Competence Sequentially: From the Perspective of RBV Name of Institute：National Chi Nan University Pages：76 Graduation Time：June/2010 Degree Conferred：Master Student Name：Shi -Ping Wu Advisor Name：Hsin Mei Lin Abstract There are two viable paths for a firm to build competence. On the one side, firms utilize existing technology-oriented resource through inside-out route to develop new competence, on the other side firms utilize existing market-oriented resource through outside-in route to develop new competence. Traditionally, scholars suggests small-sized firm, who usually constrained by limited resource prioritize to develop technology-oriented competence to enter other markets sequentially (Wernerfelt, 1984). However, in practice, we observe contradiction that the TFT-LCD manufacturing suppliers in Taiwan adopt the market-oriented perspective so as to first respond to market demand for order income, and then learn advantage technology from foreign contractors. It is an interesting phenomenon that motive to resolve the gap between the theoretical argument and practice. Thus, we explore the sequential differences between inside-out route and outside-in route, and to differentiate technology competence and market competence. This research was using the extended case method (Burawoy, 1991) compared two Taiwan international enterprises that produce TFT-LCD manufacturing equipment. This article found that technology-orientation tends to emphasis more on research and development, organizational learning, innovation and design. On the other hand, market-orientation emphasizes much on the linking relations with other manufacturer, reputation, communication and service innovation.

The objective of this research are to prepare powders of titanium-doped zinc oxide (ITiO) by co-precipitation method, to produce ITiO targets through ceramic processing using these powders, and to deposit transparent conducting ITiOthin films by RF magnetron sputtering. In addition, the effects of the amount of titanium dopant in the ITiO targets as well as other sputtering parameters on the structural, electrical and optical properties. Finally, we are going to utilize ITiO thin films on CIGS solar cell element, and the impacts of ITiO materials on photoelectric effect are also investigated. From the experimental results, we found that the properties of the ITiO materials were sensitive to the conditions in the co-precipitation process. Polycrystalline ITiO powders were synthesized by calcining the precursors co-precipitated at pH=7 the processes of filtering, washing and drying. ITiO targets with relative density 95.54% and electrical resistivity 3.4×〖10〗^(-4) Ωcm were obtained by sintering the ITiO green bodies made from these ITiO powders through the processes of granulation, dry pressing andde-waxing. The optical transmittance and electrical resistivityof the ITiO thin films deposited using 1wt% titanium containing targets at the conditions of substrate temperature 250oC, working pressure 3×〖10〗^(-3)torr, working gas flow rate, and sputtering power 80W were 72.95% and around 2.72×〖10〗^(-4) Ωcm Eventually, CIGS sloar cell element was deposited using 2wt% titanium containing targets at the conditions of substrate temperature 150oC, working pressure 3×〖10〗^(-3)torr, working gas flow rate, and sputtering power 80W. Then, the efficiencyη=8.323% which iscrried out by photovoltaic conversion instrument .
