How Transnational Advocacy Networks Emerge:  An Empirical Investigation of a Casualty Recording Network

Ruiz, Jeanette Renee 02 March 2023 (has links)
This research contributes to gaps in the international relations literature explaining the emergence of transnational advocacy networks. Specifically, this research contributes to understanding TAN emergence due to a gap in institutional approaches to casualty recording in conflict and why actors join TANs. This TAN is particularly worthy of investigation because casualty records measure the scope of violence in a conflict and are often highly politicized and contested. Existing explanations of TAN emergence can be organized into three broad categories of analysis: sociological, political, and economic. The earliest explanations align with a sociological explanation for TANs as a mechanism for changing international norms. Social movement theorists account for TANs as a mechanism for civil society to challenge power structures. While other researchers suggest TANs should be treated like interest groups, and their emergence stems from an economic need for material incentives. This research extends the economic category of analysis and argues that actors join TANs for non-material, intangible incentives. Intangible benefits include knowledge, methodologies, data, or access to data sources. This research utilized a qualitative case study method to test all three categories of existing explanations using surveys, interviews, and archival records. Testing not only investigated hypotheses relating to the three categories of existing theories but also produced findings describing facilitators of TAN emergence, temporally-bound intangible benefits, and the types of intangible benefits available to actors. TANs are important to international politics because they influence norms, shape policies, and function as a bridge for local actors with the international community. This research produced findings with central themes about why resource-poor actors may spend their limited resources to join TANs. Further investigation into the intangible benefits available to actors joining TANs in settings other than conflict may provide greater insight into the value of intangible benefits to collective behavior. / Doctor of Philosophy / While body counts are generally presented as a measure of accountability or to raise awareness about civilian deaths in the public sphere, body counts are fiercely contested and highly politicized. This occurs during the conflict and decades after a conflict is resolved. Civilian body counts serve as political apparatuses for states and political actors to negotiate, challenge, and produce security narratives. Because of this politicization, the number of civilian casualties in violent conflict is not fully known, and their deaths' impact on the overall state's security is not well understood. While International Humanitarian Law (IHL) and human rights laws provide protection for civilians in conflict, documenting casualties is not addressed. International law does not prescribe methods for recording casualties; therefore, there is a gap in how international institutions approach accounting for casualties. In the early 2000s, facilitated by ICTs, civil society began to fill this gap by documenting casualties and collaborating across boundaries. This research traces the emergence of a Transnational Advocacy Network (TAN) that appeared in 2009 to collaborate on recording conflict casualties. This study produced five findings and contributes to understanding how ICTs facilitate TANs and identifying intangible benefits available to actors at network events that motivate their participation. Intangible benefits include knowledge, methodologies, data, or access to data sources. This research is worthy of investigation because TAN development is poorly understood yet they influence international politics by shaping norms, policies and linking local communities with international organizations.

Design and Optimization of InterCell Transformers for Parallel MultiCell Converters / Dimensionnement et optimisation de Transformateurs Inter-Cellules pour les convertisseurs multicellulaires parallèles

Cougo França, Bernardo 29 October 2010 (has links)
Les convertisseurs multicellulaires parallèles permettent de traiter des puissances importantes et de profiter d'une certaine standardisation des équipements. Ces dernières années, ces structures ont connu un regain d'intérêt lié notamment à la possibilité de couplage magnétique des inductances. Ce couplage aboutit à un composant magnétique aux propriétés très différentes appelé Transformateur Inter-Cellules (ICT) ; il ne modifie pas le courant de sortie, par contre il réduit l'ondulation de courant dans les bobines et l'ondulation de flux dans certaines parties du noyau. On peut montrer que ce couplage entraîne une réduction des pertes Joules dans les conducteurs et des pertes magnétiques dans le noyau. La réduction de l'ondulation de courant diminue également le courant efficace dans les semiconducteurs ce qui réduit les pertes par conduction, et la différence entre le courant à l'amorçage et au blocage des interrupteurs, ce qui permet la diminution des pertes dans les semiconducteurs lorsque les pertes au blocage sont supérieures aux pertes à l'amorçage. Le dimensionnement d'un ICT n'est pas fondamentalement différent de celui fait pour d'autres composants magnétiques en ce sens qu'il est basé sur le respect de certaines valeurs limites (induction, température) ce qui suppose une évaluation des différentes pertes et l'élaboration d'un modèle thermique. Par contre, la manière d'évaluer ces différentes grandeurs est tout à fait spécifique et n'a que quelques points communs avec les méthodes de calcul des inductances et des transformateurs Dans ce travail de thèse, on montre comment dimensionner ces ICTs en considérant plusieurs topologies et méthodes différentes, correspondant à différents niveaux de sophistication et de complexité. L'explication de ce dimensionnement est divisée en quatre parties : Pertes Cuivre, Pertes Fer, Densité de Flux de Saturation et Aspects Thermiques. L'évaluation des pertes cuivre liées aux composantes alternatives des ICTs constituent un point particulièrement délicat dans la mesure où elles résultent de la combinaison de deux facteurs eux-mêmes difficiles à évaluer ; l'inductance de fuite qui détermine l'amplitude des courants alternatifs mais dépend des flux principalement non canalisés et circulant dans l'air (volume d'étude important, effets 3D…), et la résistance équivalente des bobinages qui en haute fréquence est sujette à des phénomènes complexes comme les effets de peau et de proximité. En se basant sur l'utilisation d'un logiciel simple mais néanmoins robuste et fiable pour calculer précisément les résistances en haute fréquence et les inductances de fuite des ICTs, plusieurs astuces permettant de réduire les pertes cuivre non seulement des ICTs mais aussi des transformateurs et des inductances sont suggérées. Des tableaux simples sont développés pour aider le concepteur de transformateurs à identifier la meilleur configuration de conducteurs dans une fenêtre de bobinage en prenant en compte la forme d'onde du courant, le nombre de tours des enroulements, la fréquence des courants et les paramètres géométriques. Des formules analytiques et des outils de calcul adéquats ont ensuite été utilisés pour développer des routines d'optimisation ayant pour but la réduction de la masse, du volume, des pertes ou du coût des ICTs. Des interpolations multidimensionnelles des valeurs présimulées des résistances et inductances de fuite en haute fréquence sont utilisées afin de réduire le temps d'exécution de la routine d'optimisation. Plusieurs dimensionnements des ICTs ont été comparées vis-à-vis des matériaux du noyau et des conducteurs, du nombre de cellules de commutation et de la fréquence de découpage. Des comparaisons avec des selfs ont également été faites afin de montrer les avantages de ces ICTs. Des aspects de la commande des convertisseurs multi-niveaux triphasés ont également été étudiés vis-à- is du flux circulant dans les ICTs. Des homopolaires, spécifiques pour chaque stratégie MLI et chaque topologie convertisseur/charge, sont créées afin de minimiser le flux dans les ICTs et par conséquent de réduire davantage la masse et la taille de ces composants. Des comparaisons entre différentes méthodes de MLI sont effectuées et vérifiées expérimentalement. / In recent years, the interest for parallel multicell converters has grown, which is partially due to the possibility of coupling the inductors used to connect the different commutation cells together. Coupling the inductors to form an InterCell Transformer (ICT) does not usually modify the output current, but it reduces the current ripple in the windings and the flux swing in some regions of the core. It can be shown that this brings a reduction of copper and core losses in the magnetic component. The reduction of the phase current ripple also reduces the difference between turn on and turn off current in the switches, which brings a reduction of switching losses for devices generating more losses at turn off than at turn on. The design of an ICT is not that different from any other magnetic component but it is very specific and inherent features must be taken into account. Taking full benefit of the potential advantages of ICTs requires the development of special tools and methods which are the focus of the study. We show how to design ICTs considering several topologies and different methods, from the most precise and time-consuming to the less accurate but more quickly calculated. The explanation of the ICT design is divided in four main parts: Copper Losses, Core Losses, Flux Density Saturation and Thermal Aspects. Further attention is given to high frequency copper losses since complex phenomena such as skin and proximity effects highly influence the ICT design. Based on Finite Element Method simulations, smart practices are suggested to reduce high and low frequency copper losses, not only in ICTs but also in inductors and transformers. Simple tables are developed to help transformer designers to identify the best configuration of conductors inside a given core window, depending on the current waveform and frequency, number of turns and geometrical parameters. Optimization routines to reduce the ICT total mass, volume, losses or cost are developed and multidimensional interpolation of pre-simulated values of AC resistance and leakage inductance is used to speed up the optimization routine. Comparison of ICT designs with regard to core and conductor material, number of cells and switching frequency is performed. Comparison with regular inductors is also made in order to verify the benefits of this kind of magnetic component. Multilevel converter control aspects applied to three- hase systems is also investigated in terms of the ICT flux. Zero sequence signals, specific for a PWM strategy and converter/load topology, are created in order to minimize the flux in ICTs and consequently reduce even further the mass and size of these components. Comparison between several PWM methods are performed and experimentally verified.

Adoption, diffusion and use of e-government services in the Abu Dhabi police force

Al-Zaabi, Hassan Jumaa January 2013 (has links)
Information and Communication Technologies (ICTs) are becoming increasingly prevalent in peoples’ daily lives due to the presence of e-government. This research aims to identify and understand factors affecting the adoption and use of e-government services in a public sector organisation in a developing country, in this case, Abu Dhabi Police Force (ADPF) in the United Arab Emirates (UAE). For this purpose a theoretical framework based on existing e-government and e-services literature was developed. To determine its applicability, a qualitative approach involving 200 participants’ interviews was used in this study. The questions for the interviews were based on the constructs derived from classic theories in the literature. The theories are: Diffusion of Innovations Theory (DOI), Technology Acceptance Model (TAM), Decomposed Theory of Planned Behaviour (DTPB) and e-Commerce’s Trustworthiness models. The research study results revealed that departments that had roles and responsibilities aligned with government online products and services, adopted e-services better. Where training and awareness was provided, individuals adopted e-services better, and where trust in the provision of e-services was divided in two. The first relates to e-services being better than a manual service as e-services provide clarity and transparency. The second form of trust aligns with confidentiality and privacy. A subset of the research revealed that demographic factors that include, an organisational structure position and the role that one has, inhibit or encourages the use and adoption of e-services. The contributions from this research are anticipated to be a better understanding of the adoption, diffusion and use of e-services in the UAE region. For theory, this research study provided a diverse approach (qualitative research) in an organisational context, the development of a conceptual framework specific to Abu Dhabi’s public sector department and finally, there is research conducted on government to employee e-services in Abu Dhabi, a rare occurrence. For policymakers, the contribution of this research is that the research can understand the impacts of policies and strategies used for developing and implementing e-services. For practice the contribution can be in the form of results that organisations providing external consultancy services in the UAE can identify and understand. Therefore, results such as, lower positions individuals in departments not utilising e-services emerged and suggest that awareness should be inherent within the organisation. By doing so, fewer risks and waste of resources in the form of time and personnel can be avoided.

The Influence of Communication for the Future of the Physical Workplace

Hauksdóttir, Helga January 2019 (has links)
The aim of the study was to examine employees' attitudes towards work shifting to the digital space and whether there will still be a need for the physical workplace in the future in relation to the development of information and communication technologies. For this study a survey was conducted to answer the following questions; how is the digital transformation of work affecting the workplace for employees in the Icelandic tech sector, what are the factors that affect the choice of workspace, and how can the choice of office space influence job satisfaction? Literature and theories about workplace development, digitalization, organizational communication and information, and communication technologies were used to gain a broader and deeper knowledge of the field. The study shows that it is likely that there are still some changes to take place in today's workplaces and that increased flexibility is one of those changes as 94.9% of participants in this research thought flexibility was an important feature for the organization to possess to be an attractive workplace. Face-to-face communication is more effective and there is still a need for the physical workplace according to the participants of this study. It is essential for organizations today to stay attractive and become more attractive in the eyes of current and future employees. The workplace needs to be a place where employees feel good and where they prefer to work so that face-to-face communication and relationships between co-workers and managers does not only take place in the digital environment. A balance between the physical and virtual office space needs to be the focus for organizations in the coming years. Subsequently, the results were compared with the theories and previous studies.

Introdução à ciência - uma disciplina para alunos de graduação / Introducing undergraduate students to Science

Avila Júnior, Paulo de 09 April 2010 (has links)
O aprendizado do método científico estimula o desenvolvimento do pensamento crítico e a análise lógica de informações. Além disso, a proposição e teste de hipóteses são aplicáveis não só à ciência, mas também para fatos comuns da vida diária. Saber como a ciência é feita e seus resultados publicados são úteis para todos os cidadãos e obrigatório para os estudantes de ciências. Uma disciplina de 60-h (QBQ2006 - Introdução à Ciência) foi criada para oferecer aos estudantes de graduação uma forma sistemática de aprendizagem dos procedimentos de produção e publicação científica. A disciplina foi composta por dois módulos e seu foco principal era a bioquímica. O Módulo I explorou artigos científicos e o Módulo II a escrita do projeto de pesquisa. O Módulo I abordou os tópicos: (1) a diferença entre o conhecimento científico e o senso comum; (2) diferentes concepções de ciência; (3) metodologia científica; (4) categorias publicação científica; (5) princípios de lógica; (6) dedução e indução; e (7) leitura crítica de artigos científicos. O Módulo II abordou: (1) seleção de um problema experimental para investigação; (2) revisão bibliográfica; (3) materiais e métodos; (4) apresentação e escrita de projeto; (5) agências de financiamento; e (6) análise crítica de resultados experimentais. O curso adotou uma estratégia de aprendizagem colaborativa, e cada tópico foi estudado por meio de atividades a ser realizadas pelos alunos. Avaliações qualitativas e quantitativas do curso, com questionários do tipo Likert, foram realizadas em cada oferecimento e os resultados mostraram grande aprovação da disciplina pelos alunos. Os professores responsáveis pelo planejamento e desenvolvimento da disciplina também a avaliaram positivamente. O Departamento de Bioquímica do Instituto de Química da Universidade de São Paulo ofereceu essa disciplina quatro vezes. Aproveitando os recursos fornecidos pelas Tecnologias da Informação e Comunicação (TIC) e da experiência adquirida com o primeiro oferecimento da disciplina QBQ2006 foi criado, adaptada desta, outra disciplina de 60h, com o mesmo nome, na modalidade à distância (IC01 - Introdução à Ciência). Foi oferecida aos alunos de graduação dos cursos de Nutrição, Biomedicina e Medicina da Fundação Faculdade Federal de Ciências Médicas de Porto Alegre (FFFCMPA) atual Universidade Federal de Ciências da Saúde de Porto Alegre (UFCSPA). A disciplina foi composta por dois módulos e adotou estratégia de aprendizagem colaborativa, como descrito na experiência anterior. Avaliações qualitativas e quantitativas do curso, com questionários do tipo Likert, foram realizadas em cada oferecimento e os resultados mostraram a grande aprovação pelos alunos da disciplina. Os professores responsáveis pelo planejamento e desenvolvimento da disciplina também a avaliaram positivamente. A disciplina IC01, Introdução à Ciência, foi oferecida três vezes / Understanding the scientific method fosters the development of critical thinking and logical analysis of information. Additionally, proposing and testing a hypothesis is applicable not only to science, but also to ordinary facts of daily life. Knowing the way science is done and how its results are published is useful for all citizens and mandatory for science students. A 60-h course (QBQ2006 - Introduction to Science) was created to offer undergraduate students a framework in which to learn the procedures of scientific production and publication. The course\'s main focus was biochemistry, and it was comprised of two modules. Module I dealt with scientific papers, and Module II with research project writing. Module I covered the topics: (1) the difference between scientific knowledge and common sense, (2) different conceptions of science, (3) scientific methodology, (4) scientific publishing categories, (5) logical principles, (6) deductive and inductive approaches, and (7) critical reading of scientific articles. Module II dealt with (1) selection of an experimental problem for investigation, (2) bibliographic revision, (3) materials and methods, (4) project writing and presentation, (5) funding agencies, and (6) critical analysis of experimental results. The course adopted a collaborative learning strategy, and each topic was studied through activities performed by the students. Qualitative and quantitative course evaluations with Likert questionnaires were carried out at each stage, and the results showed the students\' high approval of the course. The staff responsible for course planning and development also evaluated it positively. The Biochemistry Department of the Chemistry Institute of the University of São Paulo has offered the course four times. Taking advantage of the resources provided by the Information and Communication Technologies (ICTs) and the experience gained with the first offering of the course QBQ2006 another 60h course was created in distance mode (IC01 - Introduction to Science). It was offered to undergraduate students of Nutrition, Biomedicine and Medicine from the Fundação Faculdade Federal de Ciências Médicas de Porto Alegre (FFFCMPA) current Universidade Federal de Ciências da Saúde de Porto Alegre (UFCSPA). The course was comprised by the two modules and adopted a collaborative learning strategy, as described in the previous experience. Qualitative and quantitative course evaluations with Likert questionnaires were carried out at each stage, and the results showed the students\' high approval of the course. The staff responsible for course planning and development also evaluated it positively. The IC01, Introduction to Science, course was offered three times

Informação, conhecimento e valor / Information, knowledge and value

Lopes, Ruy Sardinha 22 September 2006 (has links)
Esta tese analisa o papel da informação, do conhecimento e das novas tecnologias de informação e comunicação (TICs) no atual estágio do capitalismo, em curso desde o final da década de 1960. Reconhece a centralidade econômica destes elementos e as mudanças significativas na lógica do sistema de acumulação e reprodução capitalista, embora se contraponha àqueles que advogam tratar-se do surgimento de uma nova ordem societária \"pós-capitalista\" ou que atribuem às novas tecnologias, notadamente às redes eletrônicas, papel democratizante e emancipador. Ao inserir a informação e o conhecimento no campo das relações contraditórias do capital e vê-los, portanto, como \"produtivos\", este trabalho verifica a pertinência dos antigos mecanismos de obtenção e controle do valor, assim como de subordinação da força de trabalho diante desta nova matéria - o \"intelecto geral\" - que agora se impõe.Um destaque especial é dado às dificuldades e incoerências geradas pela tentativa de adequar tal matéria à sua lógica reprodutiva. Analisa também a dialética entre a vocação \"desterritorializante\" do capital, sua busca por maior flexibilidade e liquidez, e as necessidades \"territoriais\" dos poderes locais e das infra-estruturas tecnológicas que lhes dão sustentação Aborda, por fim, as subjetividades geradas por esse processo e a possibilidade destas se contraporem ao estado atual das coisas. / This thesis analyzes the role of information, knowledge and new information and communication technologies (ICTs) in the current stage of capitalism in place since the end of the 1960\'s. It acknowledges the economic centrality of these elements and the significant changes in the logic of the capitalist system of accumulation and reproduction, even though it opposes that which some advocate as the beginning of a new, \"post-capitalist\" social order, or the democratization and emancipation role attributed to these new technologies, notably electronic networks. By placing information and knowledge in positions contrary to capital, and, therefore seeing them as \"productive,\" this research verifies the pertinence of older mechanisms of obtaining and controlling value, as well as the subsumption of the labor force in the face of this new phenomenon, the \"general intellect\" which now imposes itself. This research places special emphasis on the difficulties and inconsistencies generated by the attempt to reconcile such phenomenon with its reproductive logic. It also analyzes the dialectic between capital\'s \"de-territorializing\" tendency, its push toward more flexibility and liquidity, and the \"territorial\" necessities of the local forces and technological infrastructures that sustain them. Lastly, it addresses the subjectivities generated by this process and the possibility that these oppose current phenomenon.

Etude communicationnelle des usages des TIC dans le milieu éducatif sénégalais : le cas des lycéens de Dakar / A study of the use of ICTs in Senegalese educational environment : the case of high school students in Dakar

Ndiaye, Mbemba 05 December 2017 (has links)
Les technologies de l’information et de la communication (TIC) occupent une place importante dans les débats publics sénégalais. En outre, elles semblent être au centre des préoccupations des dirigeants de ce pays, car les espoirs qu’elles suscitent dans le domaine de l’éducation sont assez nombreux. Mais, l’introduction des TIC dans les lycées soulève également des interrogations de la part des chercheurs et des acteurs éducatifs quant à leurs usages. Cette thèse porte sur les pratiques numériques des lycéens. L’objectif que nous poursuivons est de comprendre dans quelle mesure les usages des TIC peuvent leur permettre de s’approprier des savoirs. Ici, comprendre c’est, s’intéresser aux représentations, aux connaissances et aux compétences qui impliquent l’usage des outils informatisés, mais aussi aux sens des usages. La question des usages des TIC par les élèves suscite un intérêt particulier auprès des chercheurs de certaines disciplines, particulièrement ceux de la sociologie des usages, des sciences cognitives et des sciences de l’éducation. Ainsi, nous avons privilégié une approche théorique pluridisciplinaire et une pluralité méthodologique (le questionnaire, l’observation directe et l’entretien d’explicitation) en ayant recours à des outils spécifiques pour recueillir les données (dictaphone, notes, captures d’écrans). L’analyse a permis de voir que ces usagers-apprenants s’approprient les technologies numériques à des fins d’apprentissage et a mis en relief le « versant sombre » de leurs pratiques. Partant des données obtenues nous proposons quelques pistes de réflexion pour une intégration optimale des TIC dans les pratiques d’enseignement et d’apprentissage. / Information and communication technologies (ICTs) are central to Senegalese public debates. Moreover, the leaders of this country view them as very advantageous to education. However, their introduction in high schools raises a lot of questions from both researchers and educators as regards their usage. This study is about digital practices of high school students Our aim is to understand the extent to which the use of ICTs can enable them to acquire knowledge. Understanding in this regard implies looking at the perceptions, knowledge and skills related to the use of computerized tools, but also the meanings of this usage. The use of ICTs by pupils is also of particular interest to researchers in the fields of humanities and social sciences, especially those in the sociology, cognitive sciences and education areas. Thus, in order to better define the subject, this study used a multidisciplinary theoretical approach and a plural methodology (questionnaires, direct observation and interviews) as well as specific tools (voice-recorder, notes and screenshots) to collect data during two field investigations that were conducted in Dakar secondary schools (from March to April 2013 and November to December 2015). The analysis revealed that these learner-users use digital technologies for learning purposes but also highlighted the "dark side" of their practices. On the basis of the data obtained, we also suggest ways in which ICTs can be optimally integrated in teaching and learning practices.

Attribution des technologies de l'information et de la communication pour les activités sociales des personnes âgées / Allocation of information and communication technology for social activities of the elderly

Atarodi, Siavash 29 June 2017 (has links)
Cette thèse, inscrite dans le cadre d’un projet de recherche européen, s’intéresse au problème des réticences des personnes âgées à l’usage des TIC. Plus précisément, elle porte sur les facteurs psychosociaux influençant les attitudes des personnes âgées de 62 ans et plus à l’égard des TIC. Nous avons mené six études dans ce cadre, répartis en deux axes. Le premier axe, comportant deux études, concerne les stratégies publiques et pratiques d’orientation des personnes âgées vers les TIC. Dans la première nous avons analysé les pratiques des organismes impliqués dans l’orientation des personnes âgées vers les gérontechnologies en Lorraine. Il en ressort que les parcours d'accès sont très différentes en fonctions des départements et des localités, mais aussi en fonction du premier interlocuteur sollicité par la personne âgée et ses proches. La seconde étude avait pour objectif d’analyser les stratégies publiques et réglementations visant à inciter et faciliter l’usage des services basés sur les TIC destinés aux personnes âgées dans six régions d’Europe. Différentes étapes de développement de ces stratégies en sont ressorties et un décalage Nord/Sud a été constaté. Dans le second axe, comportant quatre études, nous avons étudié sous différents angles les facteurs influençant les attitudes des personnes âgées à l’égard des TIC. La troisième étude visait à connaître les perceptions des personnes âgées à l’égard des TIC et leurs besoins perçus. Nous avons identifié 22 items relevant de perceptions, répartis en huit composantes formant une échelle des perceptions à l’égard des TIC ainsi qu’une échelle des besoins perçus en deux composantes. La quatrième étude a évalué l’impact de l’expérience antérieure avec les TIC sur les perceptions à l’égard des TIC. Nous avons réalisé des analyses de variance des perceptions à l’égard des TIC en fonction de la possession ou non d’un ordinateur et du suivi ou non de cours d’initiation à l’informatique. Les résultats ont montré que la possession d’ordinateur et le suivi de cours associés à des perceptions significativement plus positives des TIC. La cinquième étude a analysé l’impact de la région d’habitation sur les perceptions à l’égard des TIC. Nous y avons comparé les perceptions des personnes âgées de six régions de l’Ue. Nous avons constaté une cohérence entre les stratégies publiques d’orientation des personnes âgées vers les TIC et les perceptions des personnes âgées à l’égard des TIC. Enfin, notre dernière étude portait sur l’analyse des facteurs influençant l’attitude à l’égard des TIC en fonction de différents types d’activités. Suivant la variable dépendante, différents facteurs ont été trouvés, incluant des perceptions à l’égard des TIC, des besoins perçus, l’expérience antérieure, la région d’habitation et des variables sociodémographiques. / This thesis, which was part of a European research project, focuses on the problem of the reluctance of elderly people to use ICTs. More specifically, it focuses on the psychosocial factors that influence the attitudes of people aged 62 and over to ICTs. We conducted six studies in this framework, divided into two areas. The first axis, containing two studies, adresses public strategies and practices for orienting older people to ICTs. In the first one we analyzed the practices of the organizations involved in the orientation of the elderly towards gerontechnologies in the Lorraine region of France. It emerges that the access routes are very different according to the counties and communities, but also according to the first interlocutor requested by the elderly person and his / her relatives. The second study aimed to analyze public strategies and regulations encouraging and facilitating the use of ICT­ based services for the elderly in six regions of Europe. Different stages of development of these strategies emerged and a north / south lag was observed. In the second axis, with four studies, we examined from different angles the factors influencing the attitudes of the elderly towards ICTs. Our third study examined the perceptions of older persons regarding ICTs and their perceived needs. We identified 22 perceptual items divided into eight components forming a scale of perceptions of ICTs as well as a scale of perceived needs including two components. The fourth study assessed the impact of previous experience with ICTs on perceptions of ICTs. We carried out analyzes of the variance of ICT perceptions depending on whether a computer was owned or not and the follow­up of computer literacy courses. The results showed that computer ownership and course tracking were associated with significantly more positive perceptions of ICTs. The fifth study analyzed the impact of the region of residence on perceptions of ICTs. We compared the perceptions of the elderly in six regions of the EU. We found coherence between public strategies for orienting older people to ICTs and the perceptions of older people regarding ICTs. Finally, our latest study focused on the analysis of factors influencing attitudes toward ICTs for different types of activities. Depending on the dependent variable, different factors were found, including perceptions of ICTs, perceived needs, prior experience, region of residence and socio­demographic variables.

As questões focos deste estudo consistem em analisar se: O setor bancário, que aplica o conceito de planejamento estratégico de forma efetiva, utiliza de maneira articulada as TIs com a estratégia de negócio? De que forma os sujeitos usuários dessas tecnologias utilizam a informação para obter maior efetividade aos seus planos de negócio? Nesse sentido, como visão de processo de investigação científica adotou-se a estratégia qualitativa. O método de pesquisa para atingir os objetivos propostos foi o estudo de caso. Como instrumentos de coleta de dados aplicaram-se um questionário junto aos clientes PJ que utilizam o aplicativo GEFIN e uma entrevista aos membros da carteira PJ (Posto Efetivo, Assistente de Negócio e Gerente de Contas). A idéia central foi comparar de forma clara e precisa essas, a fim de constatar se realmente a ferramenta tecnológica GEFIN possibilita de forma harmoniosa o diálogo entre esses clientes e Banco do Brasil. Os resultados da pesquisa possibilitaram visualizar que é imperativo ao Banco do Brasil, que compõe um setor extremamente competitivo e dinâmico, buscar não somente em sua plataforma tecnológica, mas também em outras ferramentas organizacionais, como a gestão estratégica da informação, o planejamento estratégico de negócios deve estar alinhada às tecnologias de informação e às melhores práticas em inteligência competitiva organizacional, buscando assim novas maneiras de pensar a gestão estratégica de negócio de uma maneira mais ampla. / This study investigates and analyzes the flow of information between the Bank of Brazil (Agency Houses of Campo Grande, Mato Grosso do Sul) and their corporate clients to identify strategic alignment between business management and information technology (IT), using the Application Manager service (GEFIN). The issues focus of this study are to examine whether: The banking sector, which employs the concept of strategic planning effectively, using a comprehensive approach to IT with the business strategy? How the subjects users of these technologies use the information to obtain greater efficiency to their business plans? Accordingly, my view of the research process we adopted the strategy on quality. The research method to achieve the proposed objectives was the case study. As instruments of data collection were applied a questionnaire to the customers who use the PJ GEFIN application and interview members of the portfolio PJ (Actual Position, Assistant Business Manager and Accounts). The central idea was to compare and clearly need these to see if indeed the technological tool allows GEFIN smoothly dialogue between the customer and the Bank of Brazil. The survey results made it possible to see that it is imperative to the Bank of Brazil, which make up a sector highly competitive and dynamic, seeking not only in its technology platform, but also in other organizational tools such as strategic information management, strategic planning business should be aligned to information technologies and best practices in competitive intelligence organization, guided by new ways of thinking about strategic management of business more broadly.
