Contribution à l'étude de la sûreté de fonctionnement et de la continuité de service des bus DC / Contribution to Study of the Operation Safety and Service Continuity of DC Bus

Jamshidpour, Ehsan 22 May 2014 (has links)
Les Systèmes électriques à Puissance Distribuée (SPD) sont utilisés dans de nombreux secteurs industriels. La sûreté de fonctionnement (SDF) et la continuité de service de ces SPDs sont aujourd'hui des préoccupations majeures. Une stratégie de gestion globale de l'énergie adaptée ainsi que leur stabilité sont des exigences fondamentales pour que ces systèmes puissent fonctionner correctement. La présence de charges déséquilibrées ainsi que les interactions entre convertisseurs dans ces systèmes peuvent conduire à l'instabilité du bus DC commun. Un des cas les plus connus en terme de cause d'instabilité est celui d'une charge "à puissance constante" (CPL). Par ailleurs, toute défaillance au niveau de l'interrupteur commandable du convertisseur peut provoquer de graves dysfonctionnements du système. Tout défaut non détecté et non compensé en temps réel peut rapidement mettre en danger l'ensemble du système de puissance. Par conséquent, la mise en oeuvre de méthodes efficaces et rapides de détection et de compensation de défaut est impérative. Afin d'assurer la continuité de service de ces systèmes. Dans ce mémoire, nous étudions la gestion de l'énergie, la stabilité et la continuité de service d'un DC-SPD. Après l'étude de la gestion de l'énergie et la stabilité du système, une méthode de stabilisation active décentralisée est proposée afin d'augmenter le domaine de stabilité du SPD et afin deéviter l'instabilité en présence de charges déséquilibrées. Par ailleurs, des méthodes de détection de défaut au niveau d'un interrupteur commandable, efficaces et très rapides, sont également proposées. Nous présentons également une topologie de convertisseur DC-DC à tolérance de pannes, intégrant un interrupteur redondant ; dans tous les cas de défaut (court-circuit ou circuit-ouvert), cette topologie doit permettre deassurer la continuité de service du système de puissance en mode normal. Les études théoriques ont été validées par la simulation et par des tests expérimentaux / Electric Distributed Power Systems (DPS) are used in many industrial sectors. Continuity of service of these systems as well as their reliability are now of the major concerned. Energy management and stability are fundamental requirements for these systems to operate normally. In these systems, load converters exhibit Constant Power Load (CPL) behavior tend to destabilize the system. The system stability also can be threatened by unbalanced loads connected to the common bus. Furthermore, the failure of the controllable switch of the converter can cause serious malfunctions of the system. Undetected and uncompensated fault in real time can quickly endanger the entire power system. Therefore, the implementation of effective and rapid fault detection methods and compensation is mandatory. In this thesis, we study the energy management, stability and continuity of service of a DC-DPS. After the study of energy management and system stability, an active decentralized stabilization method is proposed to increase the stability domain of the system and to avoid instability in the case of unbalanced loads. Furthermore, efficient and very rapid methods of fault detection for a controllable switch are also proposed. We have presented a fault tolerant topology with redundancy for a DC-DC converter, which must ensure continuity of service of the DPS in any fault conditions (open or short circuit). Theoretical studies have been validated by simulation and experimental tests

Les relations franco-libyennes entre permanence et instabilité : 1969 - 2011 / Franco-Libyan relations between permanence and instability : from 1969 to 2011

Elhar, Abdulwahab 11 July 2016 (has links)
Durant la période 1969-2011, les relations franco-libyennes ont été affectées par plusieurs facteurs qui ont conduit à leur instabilité. En effet, le régime du colonel Kadhafi marqué par les ambitions hégémoniques de ce dernier dans le monde arabo-musulman et africain ont été au cœur des confrontations avec l’Occident en général, et la France en particulier. La guerre du Tchad, ancienne colonie française sur laquelle Kadhafi avait des visées non dévoilées, illustre ces confrontations où se heurtaient deux visions antagonistes quant à son règlement. Le choc des intérêts avait fini par aboutir à la confrontation militaire. Il y a aussi l’accident de l’avion de l’UTA qui venait détériorer davantage ces relations. Enfin, la question du devenir de la Méditerranée où la France tient toujours à marquer une présence mal perçue par le colonel. D’autres facteurs ont, paradoxalement, créé un climat favorable à la continuité des relations franco-libyennes. Tel est le cas de la neutralité observée par le France à travers son refus de permettre le survol de son espace aérien à des avions américains qui allaient opérer un raid sur la Libye en 1986. Plus tôt, la France eut une attitude équilibrée lors de la guerre de 1967 entre l’Égypte et Israël, ainsi que la guerre d’octobre 1973. On peut à cela ajouter la conclusion du contrat des Mirages entre la France et la Libye en 1970. Ces positions ont d’autant été appréciées par la Libye qu’il existe entre les deux pays des relations dont les enjeux politiques et économiques sont importants. Mais l’instabilité de sa politique extérieure a décrédibilisé le colonel Kadhafi aux yeux du monde, parce qu’il ne respectait pas ses engagements internationaux. Ce qui a fini par jeter un discrédit sur la Libye. Pour redorer son blason, la Libye frappée par l’embargo, avait besoin du soutien de la France, une des puissances européennes et internationales. Quant à la révolution libyenne de février 2011, elle a été saluée par la France qui souhaitait un changement sur la scène politique du pays. Cela explique sa position à la tête des forces internationales qui ont soutenu la révolution et dont l’issue a été l’éviction mortelle du colonel Kadhafi. Mais les conséquences complexes de cette révolution mettent les élites politiques devant des défis majeurs pour la construction du pays. L’avenir des relations entre la France et la Libye dépendront nécessairement du résultat du processus démocratique en cours / In the period 1969-2011, Franco-Libyan relations were affected by several factors that have led to their instability, and their discontinuity. Indeed, from the nature of Colonel Gaddafi's political regime, and from his attemps to embody leadership in the region, ensued a confrontation with France in political circles. Chad's war strikingly illustrates this observation, as this country was the site of such push and pull factors between Libya and France. These telescoping interests reached their culmination with a military clash. The dust of war had no time to settle before the UTA plane accident came adding to the already deteriorating relations. The confrontation was fed by the discrepancy between the vision each country forms regarding Mediterranean projects. All those are factors that stressed the instability of their relations. On the other hand, some factors contributed to the convergence of these relations, and, ironically, created a climate conductive to their pursuit. Notably, the French policies towards international events was described as well-balanced and independant, starting with the 1967 war between Egypt and Israel, and from the October War in 1973, to the conclusion of the Mirage aircraft contract between France and Libya in 1970, to France refusing to let American aircraft enter French air space in order to strike Libya in 1986. Those positions were appreciated by Libya, which responded positively. In another context, political, economical and cultural questions aren't to be neglected, given their importance in both countries. Besides economic and commercial interests, Libya needed France in the strategic equation, believing French voice could make itself heard both in the European and in the international debate. However, the lack of consistency in Libyan foreign policy surely contributed to undermine Colonel Gaddafi's credibility, as he didn't meet his international commitments. Ultimately, Libya created dissatisfaction among her pairs. The 2011 Libyan Revolution presented an opportunity for France, which wanted a change in the country's political scene. This explains France's position at the head of international forces that supported the Libyan Revolution bring down Colonel Gaddafi's regime. But the complex impact that came out of this revolution created a completely different reality iu Libya, still changing today. Therefore, the political elites are confronted with major challenges regarding state-building. The relations between both countries must now rely on new data and feed on a new environment. But France will follow very closely the course of events, according to her own interests. At the same time, she needs to find a climate of agreement with the leading and local powers that make a mark on the Libyan scene today

”Det kan tyvärr bli många ibland” : - En kvalitativ studie om enhetschefers syn på personalkontinuitet inom kommunal hemtjänst / “Unfortunately, it can be many at times” : - A qualitative study about unit managers views on staff continuity in municipal home care services

Sjöblad, Emma, Ljungbeck, Sanna January 2019 (has links)
The aim of this study was to investigate unit managers views on staff continuity within municipal home care services to get a wider understanding regarding the organization’s work with staff continuity, which action dilemmas the unit managers encounter and how they handle these. The study was conducted by qualitative research through semi-structured interviews with six unit managers in one middle-sized municipality in Sweden. The results showed a diverseness in working methods regarding staff continuity between the home care services in the municipality. It was also concluded that the home care services are guided by goals and guidelines regarding staff continuity which the unit managers finds unclear and undeveloped. The conclusion highlights that the unit managers finds themselves in a position where the care users needs and requests of a staff continuity does not always match the conditions and regulations within the organization. Lastly the results showed that this position causes the unit managers to make priorities in the work for staff continuity. It can be concluded that the unit managers either finds themselves adjusting to the organizations conditions or regulations or they find solutions to meet the request and needs from the care users regarding staff continuity.

O princípio da continuidade dos serviços públicos / The principle of continuity of public services

Guimarães, Letícia 29 October 2007 (has links)
Made available in DSpace on 2016-04-26T20:26:03Z (GMT). No. of bitstreams: 1 Leticia Guimaraes.pdf: 408463 bytes, checksum: 94326497aeff0b9b9cc27b58c7cde3f5 (MD5) Previous issue date: 2007-10-29 / The present work is aimed at the study of the principle of continuity of public services and of themes related to it. In order to permit the delimitation of the work s range of application, several aspects that characterize public service were given special focus, bearing in mind that this type of service consists of the activity developed by the State in the exercise of the administrative function. Once the concept of public service had been delimited, we sought to point out the norms pertaining to the principle of continuity, as well as to understand their content. Next, a few mechanisms that ensure the enforcement of the principle of continuity were identified, mechanisms such as those that might be linked to administrative contracts, to the properties used in rendering the public service, or to the exercise of the public function. Greater emphasis was placed on the legal hypotheses that allow for the interruption of the public service. In the legal system, the following situations imposing or authorizing such an interruption were identified: when an emergency is declared; technical or safety reasons regarding the workplace; in case of default on the part of the user, taking into consideration the interests of the community; when workers that render a public service go on strike. Currently, the most controversial hypotheses in the doctrine and in the jurisprudence are the interruptions brought about by user default or by labor strikes. Our dealing with the theme regarding the interruption of public services due to user default was meant to check whether or not such an interruption is in violation of the principle of continuity. Also thoroughly examined, were the situations that demanded maintenance of the public service even in case of default, with the interests of the community in mind. Concerning the interruption of public services due to labor strikes, it was observed that the matter requires specific regulations, mainly in what regards the discipline of strikes by civil servants. In the present scenario, while the matter is not yet regulated by law, the Judiciary has been playing a relevant role by ensuring the exercise of the right to strike and, at the same time, faced with the hard fact, by laying down rules to minimize loss on the part of users. Lastly, two procedural instruments were presented the individual mandatory injunction and the public civil action requiring the State to render, or to guarantee the rendering of the public services in a continuous way / O presente trabalho destina-se ao estudo do princípio da continuidade dos serviços públicos e de temas a ele relacionados. Para permitir a delimitação do âmbito de aplicação do trabalho, foram destacados vários aspectos que caracterizam um serviço público, ressaltando-se que este consiste em atividade desenvolvida pelo Estado no exercício de função administrativa. Delimitado o conceito de serviço público, procurou-se apontar as normas que contemplam o princípio da continuidade, bem como compreender o seu conteúdo. Em seguida, foram identificados alguns mecanismos que asseguram a efetivação do princípio da continuidade dos serviços públicos, mecanismos estes que podem estar atrelados aos contratos administrativos, aos bens utilizados na prestação do serviço público, ou ainda ao exercício da função pública. Maior ênfase foi destinada às hipóteses legais que admitem a interrupção do serviço público. Foram identificadas no ordenamento jurídico as seguintes situações que impõem ou autorizam a sua interrupção: em caso de emergência; quando houver razões de ordem técnica ou de segurança das instalações; na hipótese de inadimplemento do usuário, considerado o interesse da coletividade; e a deflagração de greve dos trabalhadores que prestam serviços públicos. Atualmente as hipóteses mais controvertidas na doutrina e na jurisprudência são as interrupções ocasionadas pelo inadimplemento do usuário e pelos movimentos grevistas. A abordagem do tema relativo à interrupção dos serviços públicos em razão da inadimplência do usuário teve por objetivo verificar se tal interrupção viola ou não o princípio da continuidade. Além disso, foram perquiridas as situações que impõem a manutenção do serviço público mesmo diante do inadimplemento, tendo em vista o interesse da coletividade. Com relação à interrupção dos serviços públicos em razão de movimentos grevistas, verificou-se que a matéria necessita de regulamentação específica, principalmente no que se refere à disciplina da greve de servidores públicos civis. No cenário atual, enquanto a matéria não é regulamentada por lei, o Poder Judiciário vem desempenhando papel relevante, assegurando o exercício do direito de greve e, ao mesmo tempo, diante do caso concreto, estipulando regras para minimizar os prejuízos dos usuários. Por fim, foram apresentados dois instrumentos processuais, o mandado de segurança individual e a ação civil pública, utilizados para impor ao Estado o cumprimento do dever de prestar ou garantir a prestação dos serviços públicos de forma contínua

Terças em perfis de aço formados a frio com continuidade nos apoios: ênfase ao estudo das ligações de alma parafusadas com transpasse ou luva / Continuous cold-formed steel purlins over internal supports: emphasis on the study of overlapped and sleeved bolted connections

Fávero Neto, Alomir Hélio 19 November 2013 (has links)
Terças de aço formadas a frio são muito utilizadas em sistemas de cobertura e fechamento. Para conferir continuidade entre tramos adjacentes e possibilitar um melhor aproveitamento de material, são empregadas ligações parafusadas por transpasse e com luva. O comportamento estrutural dessas ligações é muito dependente da sua configuração geométrica e do nível de carregamento. Com base em uma série de nove experimentos e análises teóricas, o comportamento estrutural dessas ligações foi investigado no tocante aos esforços resistentes e à rigidez. Observou-se que o modo de falha tem sempre uma componente distorcional significativa e uma resistência menor que a prevista pela metodologia atual de projeto. No caso do momento fletor resistente, a distribuição de tensões de flexão oblíqua é a que melhor se aproxima do comportamento real das terças, sendo possível a partir de uma análise de estabilidade elástica considerando tal comportamento, e, baseado no método da resistência direta e na curva de dimensionamento do modo distorcional, obter uma previsão segura do momento fletor resistente. Além disso, a rigidez da ligação, com relação aos deslocamentos verticais é bastante dependente do tipo de ligação, sendo que as terças com ligações por luva são mais deformáveis que terças sem ligações. Por outro lado, terças com ligações por transpasse são menos deformáveis que terças fisicamente contínuas. As parcelas de rigidez da ligação são apresentadas, e a componente de deformação do furo é a mais significativa. Uma expressão para deduzir a rigidez rotacional da ligação é apresentada, juntamente com um modelo de barras para modelagem da ligação. Os resultados teóricos se ajustam muito bem aos experimentais. Conclui-se em linhas gerais, que as ligações por transpasse podem ser consideradas plenamente satisfatórias do ponto de vista de comportamento estrutural, sendo que terças com essas ligações são mais resistentes e rígidas que terças com continuidade física. O mesmo não ocorre nas terças com ligações por luva, porém, dada a limitação no número de ensaios, tais ligações carecem mais estudos. / Cold-formed steel purlins are widely used in roofs and wall systems. The continuity of long runs of cold-formed steel purlins is guaranteed by sleeve and overlap bolted connections, which allows a better load distribution and material savings. The structural behavior of these connections is highly dependent on their geometric configuration and load level. The strength and stiffness of these connections were determined through a series of nine experiments, numerical and analytical analysis. Results have shown that distortional buckling has a major contribution on the stability analysis of the cold-formed steel purlin. To safely determine the flexural strength of the purlin, one must consider unrestrained bending stress distribution and distortional buckling. The connection type influences the rigidity of the purlin thus the vertical displacement. Purlins with overlapped connections are stiffer than physically continuous ones, although purlins with sleeved connections are not. The bearing deformation at the connection region is responsible for a reduction in the system stiffness. To account for the change in stiffness and determine the vertical displacement, an expression for the bearing stiffness and a beam model are proposed. The results of this model show good agreement with experimental data. The general conclusion of this research is: overlapped bolted connections enhance the structural response of the purlins when compared to physically continuous ones. The same does not hold true for purlins with sleeved connections.

Regards sur la continuité de l'hellénisme chez les écrivains français du XXème siècle (1947-1967) : une image de la Grèce reconstruite / A regard to the continuity of the hellenism by the XXth century French writers (1947-1967) : un image of reconstructed Greece

Kouzini, Maria-Eleni 19 December 2012 (has links)
Ce travail se propose de définir la représentation de la Grèce chez dix voyageurs français qui visitent le pays entre 1947, fin de la guerre civile grecque, et 1967, début de la dictature des Colonels. Le corpus est constitué des écrivains suivants : Jacques Lacarrière, Robert Levesque, Jean Cau, Jean Cocteau, Roger Milliex, Michel Butor, André Malraux, Michel Déon, Jacques Chardonne et Thierry Maulnier. Tous partent avec une solide culture classique et une image stéréotypée de la Grèce, qu’ils ont à confronter avec la réalité. Les traces des guerres, des guerres balkaniques aux guerres civiles, sont très visibles, notamment dans les villes et la misère de la population est très sensible. Pourtant, les voyageurs français sont tous à la recherche des stéréotypes véhiculés en Europe. S’ils ne sont pas déçus par les paysages grecs, ils ont de la peine à retrouver les Grecs dans les Grecs. Ils se font l’écho des théories élaborées ou reprises au XIXème siècle, selon lesquelles les Grecs n’ont plus rien de commun avec les Grecs de l’Antiquité ou qu’ils sont dégénérés. Pourtant chacun fait des efforts parfois vains, pour trouver une continuité dans la Grèce, en confrontant types humains contemporains, moeurs et coutumes, voire langue, aux réalités correspondantes antiques. L’élément religieux, dont ils n’ignorent pas qu’il constitue une rupture, est analysé en terme de syncrétisme, ou clairement rattaché à Byzance, considérée comme une étape de l’histoire de la Grèce. Mais il ressort de l’ensemble des textes, plus ou moins explicitement, que les véritables héritiers de la Grèce antique sont les Européens, auprès desquels les Grecs peuvent réapprendre à être ce qu’ils étaient autrefois. / The present research work suggests to delineate Greece through the delicacy of ten French travelers who visit the country between 1947, the end of the Greek civil war, and 1967, the beginning of the military dictatorship. The corpus comprises the undermentioned authors: Jacques Lacarrière, Robert Levesque, Jean Cau, Jean Cocteau, Roger Milliex, Michel Butor, André Malraux, Michel Déon, Jacques Chardonne et Thierry Maulnier. All of them set out accompanied with a solid classical culture and a conventional concept of Greece, which requires the contrast with the « real world ». The traces of the warfare, from the Balkan wars to the civil wars, are evident, notably in the towns where the population is visibly poverty-stricken. Nevertheless, the French travelers are searching for the European conveyed stereotypes. Although they are not disappointed by the Greek landscape, they hardly recognize the Greek people. They echo the 19th century elaborate or resumed theories according to which the Greeks have nothing in common any more with the Ancient Greeks or rather they have degenerated. However, each one of them endeavors vainly at times to find continuity with Greece by comparing contemporary human types, modus vivendi and customs even the language, with corresponding ancient situations. The religious element, of which they are conscious that it constitutes a splitting component, is analyzed in terms of syncretism, or it is intelligibly associated with Byzantium and considered to be an important stage in the history of Greece. All the same, it stands out from the entire written work of art, more or less explicitly, that the real inheritors of Ancient Greece are the Europeans, to the side of whom, the Greeks can learn anew how to become the people they used to be.

O objetivo desta pesquisa investigar os fatores que mais influenciam a intenção de continuidade dos membros participantes de uma rede de cooperação no segmento varejista. Logo, utiliza-se uma pesquisa qualitativa exploratória preliminar, como forma de suportar uma pesquisa quantitativa principal, a partir de uma survey. Uma amostra de 150 proprietários de farmácias, que pertencem à rede, responderam um questionário eletrônico, que fora utilizado como base para uma análise descritiva, teste de hipóteses e regressão linear. A ideia de que o associativismo promova benefícios para farmácias independentes, oferecendo melhores condições de competir em um cenário dinâmico, dominado por grandes redes, e a busca do entendimento dos fatores que antecedem a continuidade na rede, permeiam a condução da pesquisa. Os resultados principais mostram que a continuidade está mais fortemente associada à maior satisfação, maior aprendizagem e maior desempenho do membro da rede. Além disso, observou-se que empresários com um tempo maior de rede e com orientação estratégia direcionada para qualidade possuem maior intenção de continuidade. / Several aspects related to inter-organizational relationships are explored in this research, with emphasis on constructs satisfaction, performance, learning, motivation, legitimacy, promotional tools and continuity. The objective of this research is to investigate the factors that most influence the intention of continuity of participating members of a cooperation network in the retail segment. Therefore, we use a preliminary exploratory qualitative research as a way to support a major quantitative research, from a survey. A sample of 150 owners of pharmacies, which belong to the network, answered an electronic questionnaire, which was used as the basis for a descriptive analysis, hypothesis testing and linear regression. The idea that the association promotes benefits to independent pharmacies, offering better conditions to compete in a dynamic scene, dominated by large networks, and the search for understanding the factors that precede the continuity in the network, permeate the conduct of research. The main results show that the continuity is more strongly associated with greater satisfaction, higher learning, and increased network member performance. Furthermore, it was observed that business with a longer network and orientation with an emphasis on quality strategy intended to have greater continuity.

The research aimed to analyze how teachers pedagogical coordinators of the state of São Paulo understand and describe their role as trainers of teachers. For various reasons, we chose six participants who worked in elementary schools of a single Diretoria Regional de Ensino, located in the east of the Capital. In this study, we used like procedure to collect information interviews, discourse analysis which sought grounds in qualitative research methodology. The results indicated that the work of teachers pedagogical coordinators has elements of bureaucratization and inspection of teaching, which marked the history of their profession. The efforts of participantes to develop the teachers continuing education are the result of conquests undertaken individually and marked by subjective interpretations on this task, that find explanation in the distortions between the formulation of continuity educational politics and the objective conditions work of those professionals / A formação de professores como atribuição do coordenador pedagógico apresenta-se como uma tendência que, aos poucos, vem sendo incorporada pelas políticas públicas referentes aos profissionais desta área, como é o caso do Programa Ler e Escrever, destinado às séries iniciais do Ensino Fundamental da rede estadual de São Paulo, e que esteve na base de consideração deste trabalho. A pesquisa teve como objetivo analisar como os professores coordenadores pedagógicos da rede estadual de São Paulo compreendem e descrevem sua atuação como formadores de professores. Por diferentes motivos, foram escolhidos 6 participantes que atuavam em escolas de ensino fundamental de uma única Diretoria Regional de Ensino, situada na região leste da Capital. Neste trabalho, empregou-se como procedimento de coleta de informações entrevistas individuais, cuja análise do discurso buscou fundamentação na metodologia de pesquisa qualitativa. Os resultados indicaram que o trabalho dos professores coordenadores pedagógicos guarda traços de burocratização e fiscalização do trabalho docente, que historicamente marcaram a história da sua profissionalidade.

Les facteurs explicatifs de l'adoption et de la continuité d'utilisation d'une innovation technologique : le cas de la cigarette électronique / Factors explaining the adoption and continuance use of a technological innovation : the case of the electronic cigarette

Charmi, Amina 15 December 2016 (has links)
Pourquoi certaines innovations réussissent alors que d’autres échouent ?Dans la littérature marketing, il est largement accepté que l’adoption d’un nouveau produit peut être influencée par le phénomène de la contagion sociale, c’est-à-dire par le phénomène d’imitation des comportements des autres membres du système social. Les recherches en marketing se sont donc intéressées à étudier empiriquement l’impact de la contagion sociale sur l’adoption des innovations. Or, le succès d’une innovation ne s’apprécie pas uniquement par son adoption mais aussi par la continuité de son utilisation. Ainsi, notre étude s’intéresse non seulement au premier achat mais aussi à la continuité d’utilisation de l’innovation technologique. En effet, l’analyse du comportement du consommateur sur le long terme permet de s’assurer de sa satisfaction et de la pérennité des entreprises.Pour ce faire, Nous avions mené une étude quantitative. A cet effet, un questionnaire de recherche a été élaboré et administré auprès d’un échantillon de 593 individus. Les résultats des analyses à équations simultanées montrent le rôle du leadership d’opinion ainsi que des caractéristiques perçues dans les comportements d’adoption et de continuité d’utilisation. Notre recherche contribue donc au développement des connaissances dans le domaine d’adoption et de diffusion de l’innovation et conduit à un certain nombre de recommandations managériales. / Why some innovations succeed and others fail?In the marketing literature, it is widely accepted that the adoption of a new product can be influenced by the phenomenon of social contagion, that is, the phenomenon of imitation of the behavior of other members of the social system. Marketing research was therefore interested to empirically study the impact of social contagion on the adoption of innovations. However, the success of an innovation is not only appreciated by its adoption but also its continued use. Thus, our study looks not only at the first purchase but also the continuity of use of technological innovation. Indeed, consumer behavior analysis in the long run will ensure their satisfaction and sustainability of companies.In order to do so, we had conducted a quantitative study. For this purpose, a research questionnaire was developed and administered to a sample of 593 individuals. The results of analysis with simultaneous equations show the role of opinion leadership and the perceived characteristics of innovation in the behavior of adoption and continuity of use. Our research contributes to the development of knowledge in the field of adoption and diffusion of innovation and leads to a number of managerial recommendations.

Estudo eletromiográfico do músculo masseter em indivíduos submetidos à cirurgia de terceiros molares inferiores / Electromyographic study of the masseter muscle in individuals who undergone inferior third molar surgery

Barros, Tarley Eloy Pessoa de 26 February 2008 (has links)
A cirurgia de terceiro molar é um dos procedimentos mais realizados na área de cirurgia e traumatologia bucomaxilofaciais. A evolução pós-cirúrgica era baseada em evidência clínica. No nosso trabalho, propusemos acompanhar a evolução pós-cirúrgica através da utilização do eletromiografia de superfície. Realizamos quatro tomadas, no pré-operatório, normalizando, e três no pós-operatório, 7, 14, 21 dias, em amostra de 30 pacientes. Observamos, no vigésimo primeiro dia, recuperação próxima da normalização no gênero feminino e ainda aquém no gênero masculino. Constatamos que a eletromiografia de superfície é sensível para controle da evolução pós-cirúrgica, demonstrando ser um método eficaz e seguro. / The third molar surgery is one of the most frenquently performed procedures in the buccal-maxillary-facial traumatology and surgery areas, whereas the post-surgery evolution has been based on the clinical evidence until now. In our study, we proposed to analyze the post-surgery clinical evolution through the use of electromyograph of surface. We have made four takes, on the presurgery, normalizing, and three on the 7, 14 and 21 postoperative days, in a sample of 30 patients. We observed, in the twentieth-first day, a recovery close to normalization on women, but men did not reach normalization. The electromyograph of surface is sensitive to the post-surgery evolution control, and is an efficient and safe method.
