Adoção de computação em nuvem : estudo de casos múltiplosSobragi, Cyro Gudolle January 2012 (has links)
A computação em nuvem é considerada um paradigma computacional da atualidade. Sua adoção vem crescendo nos últimos anos, contudo ainda é incipiente nas organizações brasileiras. Por ser uma tecnologia inovadora, a computação em nuvem vem recebendo maior atenção da academia nos últimos anos, contudo a abordagem do assunto na literatura de Sistemas de Informação ainda é considerada baixa, apesar de crescente. A presente dissertação tem o objetivo de analisar os fatores de adoção da tecnologia, estabelecendo uma relação entre elementos de teorias de base e fatores de adoção. Foram identificados na literatura elementos teóricos e fatores relacionados à computação em nuvem, sendo realizadas associações entre tais fatores e elementos. Os elementos teóricos identificados na revisão da literatura são oriundos da teoria dos custos de transação, teoria da dependência de recursos e teoria de difusão da inovação. A pesquisa realizada é de caráter exploratório, por meio de estudos de casos múltiplos, realizados em três empresas que já adotaram computação em nuvem. O estudo utilizou como fontes de evidências entrevistas semiestruturadas, documentos e consulta a sites corporativos das organizações pesquisadas. Para análise das entrevistas foi utilizada a técnica de análise de conteúdo, com o auxílio do software MAXQDA10. Os resultados do estudo apresentaram como fatores de adoção de computação em nuvem: confiabilidade, escalabilidade, economia, privacidade e segurança. A pesquisa também contribui para o preenchimento da lacuna na literatura de Sistemas de Informação, oferecendo subsídios para estudos quantitativos que confirmem os fatores levantados. / Cloud computing is considered a new computational paradigm for many researchers and practitioners. The adoption of this technology has been arisen in the last few years by the organizations, nevertheless it is still emerging in Brazil. As considered an innovative technology, cloud computing adoption has been gathering more attention in the academy. However, this subject in the Information Systems literature still has little attention, although increasing. This dissertation intends to analyze the adoption factors of cloud computing and establish associations between technology adoption factors and theory elements. Initially were identified in the literature of economic and organizational theories some elements related to the Diffusion of Innovations Theory, Transaction Cost Economics and Resource Dependency Theory. Then, the technology adoption factors were related directly to the cloud computing features. Consequently the theory elements were associated with the technology adoption factors. This research was exploratory, through multiple case studies in three companies that already adopted cloud computing. The data collection was made by interviews and documents analysis. To analyze the seven interviews this research used the content analysis method, using the software MAXQDA10. Thereafter, was conducted an association between the theory elements and the technology adoption factors. As main results, were confirmed as adoption factors in cloud computing: reliability, scalability, security, privacy and economy. This study also contributes for fill in a lack in the literature, as well as offer information for future quantitative researches about the technology adoption factors.

International School Leadership and the Diffusion of Distance Education in East Asian International SchoolsDungan, Jeffrey 30 September 2017 (has links)
Change is critical in most organizations. International schools attempting to redefine 21st century education for their students are innovating pedagogies and schools’ structures. However, the leader of an organization or school may be the most influential advocate for or barrier to change. International schools’ leaders continue to play a role in the diffusion of distance education. This study identified the knowledge and experience of international school leaders and identified themes that are related to the likelihood distance education would or would not be adopted by the schools they lead.
This applied dissertation describes international school leaders’ knowledge and use of innovation diffusion theory in adopting distance education into kindergarten-Grade 12 East Asia Regional Council of Schools (EARCOS). International schools are a unique niche in the global educational environment.
Triangulating data from EARCOS school leaders collected through individual innovativeness surveys and coding open-ended interview transcripts provided insight to school leaders’ knowledge and use of innovation diffusion theory when applied to adopting or rejecting the use of distance education within their schools.
Data collected in this study indicated that EARCOS school leaders’ use of formalized planning when diffusing innovations, including distance education, within their schools varied depending on the scale of the innovation and the stakeholders involved. EARCOS school leaders rated themselves higher on average in individual innovativeness when compared to other innovativeness survey normative groups. Several other key themes emerged from the data including the following: Opinion leadership and change agents play a vital role in diffusing innovations in EARCOS schools. School leaders need to be adaptable and recognize opinion leadership within their schools to diffuse innovations efficiently. EARCOS school leaders rated themselves as highly innovative but were reluctant to explore innovative ways of delivering instruction, including distance education. Distance education was not seen as relevant in EARCOS schools, even though school leaders recognized their students would be exposed to online learning upon matriculation.
Barriers to the diffusion of distance education exist in EARCOS schools including cost to develop distance education programs and courses, existing school structures, and the perceived absence of need.

Using Diffusion of Innovations to Explore Digital Gaming in Undergraduate Library InstructionRobertson, Michael James 08 1900 (has links)
Digital games and simulations are receiving considerable notice within the Library and Information Science (LIS) community. This study adds to the depth of knowledge in this area by providing research on the likelihood a hypothetical digital game delivery method for library instruction achieves sufficient adoption to justify its development. Furthermore, this knowledge will assist decision making processes for individuals debating the current or potential role of digital gaming at their institutions. In this mixed methods study, over 300 undergraduates were surveyed about their technology preferences, including digital gaming, for delivery of two forms of academic library instruction. The two forms of library instruction were (a) providing users with spatial information on physical library layout, and (b) educating users on information literacy topics and skills. Observational data was collected during the survey sessions, occurring at face-to-face library instruction sessions. Self-selected survey participants were also interviewed to further probe their survey responses. Rogers' Diffusion of Innovations was the theoretical foundation to this research. The primary innovation of study was the digital game delivery method. Detailed analysis of the survey-based data set included three nonparametric scaling methods: 1) rank-sum scaling; 2) circular triad analysis; and 3) multidimensional preference mapping. Content analysis of the observations and semi-structured interviews also occurred. Major outcomes were 1) the digital game delivery method achieved mediocre preference across both questions; 2) the audiovisual delivery method received the highest overall preference ranking; and 3) overall preference for the audio-only delivery method was remarkably low. The most important theme across the observational data was the participants' waning attention during the face-to-face library instruction sessions. The most important outcome from the semi-structured interviews was interviewees' stated appreciation for useful technologies. Over 95% of participants were so-called digital natives, that is, born post-1980. Rogers' assertion that age plays a minor role in predicting technology adoption appears warranted, since the more innovative digital game delivery method achieved mediocre overall preference.

Setting Up Shop in the Digital Bazaar – Bangladeshi Blue-Collar Service-Providers’ Adoption of a Business AggregatorShahid, Shantana January 2020 (has links)
This essay explores the early experiences of Bangladeshi blue-collar service workers in digitalising their livelihoods. It is a qualitative study that surveys and interviews service-providers in Dhaka who use the business aggregator platform Sheba.xyz, an online service marketplace, and seeks to understand what brought these self-employed micro-entrepreneurs, previously outside the digital economy, to adopt an ICT-enabled solution. The study is guided by Diffusion of Innovations (DOI) theory, one of the historically dominant paradigms in the field of communication for development (C4D). The overarching research question is, “Why did blue-collar service-providers in Dhaka adopt and use a digital business aggregator platform?” The aim is to explore what motivated/discouraged and enabled/hindered innovation adoption among a group of users previously marginalised from digital and financial inclusion. The findings suggest that adoption of Sheba.xyz among service-providers was not driven so much by a desire to digitalise one’s business per se, and as a means of mitigating a previous inability to do so. Rather, the factors that emerge from the qualitative data are other perceived relative advantages of the solution – of increase in customers, income, and opportunity. Survey respondents and interviewees also displayed strong affiliation with, and trust in, the platform provider; an alertness for fair treatment; and a drive to prosper, suggesting that they embraced a comprehensive concept and altered life situation where belonging, respect, and self-fulfilment matters, rather than narrowly adopted a new mobile application.

Determinants of market uptake of innovation in a situation of uncertainty about environmental and health risks : From BPA to nanotechnology / Etude des déterminants de l'adoption d'une innovation par les marchés en situation d'incertitude sur les risques sanitaires et environnementaux : Du BPA aux nanotechnologiesOstapchuk, Mariia 28 November 2017 (has links)
L’incertitude est présente dans toute innovation. Dans le domaine des nanotechnologies, l’incertitude qui entoure les risques sanitaires et environnementaux dont ces technologies pourraient être porteuses est si importante que la question de leur succès se pose.En partie du fait du manque de données cohérentes, il n’existe qu’une littérature empirique limitée sur les déterminants de la diffusion des nanotechnologies. Dans le cadre d’un programme de recherche sur les nanotechnologies, cette thèse a pour but d’investiguer les déterminants de l’adoption d’innovations dans une situation d’incertitude sur les risques environnementaux et sanitaires. Dans cette optique, nos travaux visent dans un premier temps à fournir une meilleure compréhension de la diffusion d’un produit qui est présent sur le marché depuis longtemps. Nous avons choisi une substance chimique très utilisée, le bisphénol A (BPA). Différentes méthodes économétriques sont appliquées afin de mieux comprendre la relation entre la consommation, la croissance économique, les nouvelles connaissances scientifiques concernant le risque et d’autres variables utilisant les données relatives au BPA. Les résultats illustrent un ensemble de facteurs qui influencent la consommation de BPA au niveau international.Dans un second temps, nous montrons dans quelle mesure cette étude permet d’éclairer la réflexion initiée sur la diffusion des nanotechnologies, notamment le nano-argent.Le comportement des différents acteurs en réponse à la production de connaissances scientifiques nouvelles sur les risques est étudié, ce qui nous permet d’aboutir à une compréhension approfondie de “développement nanoresponsable”. / Uncertainty is immanent in every innovation. Uncertainty about environmental and health risks that surround nanotechnology raises the questions of innovation success. Due in part to a lack of consistent data, there is limited empirical literature on determinants of the diffusion of nanotechnology. As part of a research program on nanotechnology, this research aims to investigate determinants of uptake of innovation in a situation of uncertainty about environmental and health risks. With this goal, as a first step, this work seeks to provide better understanding of the diffusion of a product that has been on the market for a long time. We have chosen a chemical, bisphenol A (BPA), because of the lack of historical data on nanomaterials. As a second step, we compare the results of the BPA study to nanosilver. We apply different econometric methods to gain insights into the relationship between consumption, economic growth, new scientific knowledge about risk and other variables using the data on BPA. The results illustrate a set of factors that influences the consumption of BPA at international level. The comparative study between BPA and nanosilver helps to refine the interpretation of main results and to obtain additional insights into the determinants of uptake of nanosilver. An explanatory analysis sheds light on the actions that different stakeholders undertake in response to new scientific knowledge about risk and deepens our understanding of “nanoresponsible development”.Keywords: Innovation, diffusion of innovation, product life cycle, nanotechnology, bisphenol A, risk, uncertainty, environment, health, precautionary principle, Safer by Design, responsible development

Analýza nákupního chování ve vztahu k elektromobilům / Analysis of Buying Behavior of Electric VehiclesKolmanová, Marie January 2015 (has links)
The thesis is focused on consumer behavior in relation to electric vehicles. In the beginning, the issue of alternatively fuelled vehicle is briefly introduced, including the explanation how this product is supported by the European Union. The next part is devoted to the theoretical background applied in the work. After the theoretical part, there is the literature review followed by both, the qualitative and the quantitative investigation. The results obtained were compared with the results stemming from international research projects. In accordance with the Theory of Diffusion of Innovations, the participants of qualitative survey were labelled as innovators or early adopters, for whom technical knowledge is more important. But on the other hand, for later adopters, the interpersonal relationship is more important, as they can compensate the lack of technical knowledge this way. As follows from the results of qualitative survey, decision-making connected with the acquisition of electric vehicles is influenced by the overall awareness (or knowledge, experience), then by technical characteristics of the purchase together with economic factors and by the perceived expectations of other people. Most of participants have some knowledge about electric vehicles. They often mention barriers preventing...

Šíření inovací v medicínském prostředí: Meta - analýza případových studií / Diffusion of innovations in medical setting: A meta - analysis of Case studies.Řepíková, Anna January 2013 (has links)
Diploma thesis "Diffusion of innovations in medical setting: A Meta-analysis of case studies" deals with contemporary shape of empirical diffusion research in public health and medical sociology field. By means of meta-analysis based on 23 case studies that was targeted on chosen aspects of investigation within the diffusion of innovations topic, on whole design of the research and on particular methodological procedures we arrived to wide thematic scope of these studies and their significant heterogeneity regarding methodological aspects. This fact testifies the large amount of possibilities that diffusion studies provide, even in such narrowed research area. Meta-analytical findings and studies divided into several typologies were then compared with an older study, where a pragmatic orientation of newer studies on a specific aspect of the whole process and practical task that needs to be solved, turned up. The sociological micro-theories making is then overshadowed by dealing with the actual field problems acute even more in the field of medicine. The communication processes at the level of interpersonal communication (that are, according to the generally accepted definition of diffusion of innovation, principal for the diffusive mechanism) as a dominant object of examination almost faded out....

Diffusion of Innovations of Videoconference Technology: An Instrumental Case Study Concerning Undergraduate Degree-Seeking Nontraditional LearnersCampbell, Bruce G. 01 January 2015 (has links)
This applied dissertation is an instrumental case study based on diffusion of innovations theory designed to gather student opinions regarding videoconference (VC) technology use in facilitating courses to undergraduate degree-seeking nursing students. The author of diffusion of innovations theory, Rogers (2003), recommended that more qualitative studies be conducted in education. Rogers and Jain (1968) recommended these studies should be conducted from the aspect of “receivers of innovation diffusion” (p.1) to provide feedback instrumental to implementation of technological innovations in academe. Further, Rogers stated that multiple data points should be used during the process of trialing an innovation. Therefore, a current VC course was selected from the nursing curriculum of a public state college hosting one of the largest nursing programs in the southeastern United States in which to conduct the study.
A total of 32 students participated divided equally between two sites: Main campus and Regional campus. Further divided, 22 personal interviews were conducted and two focus groups; one for each campus consisting 5 students each. Additionally, included in the data corpus were 40 hours of classroom observation plus, college provided end of course (EOC) summary statements. These data were triangulated to determine whether students would accept VC technology unchanged, accept with modifications, or reject VC technology based on first time exposure to the innovation during the 16-week semester. Student innovation decisions were: 6 students accepted unchanged, 14 students accepted with modifications, and 12 students rejected the innovation. Students who rejected the innovation were exclusively from the regional campus, which was the receiving site the majority of the semester.
First and second-cycle analyses yielded 67 codes resulting in 5 categories, which further developed into 3 emerging themes: (a) Interaction with instructors, materials, and distant students are key elements affecting adoption decisions of students regarding VC technology; (b) Student adoption decisions are influenced by faculty members in their use of VC technology; and (c) Student opinions indicate that reinvention is necessary for VC technology to be fully adopted into the present nursing program. The five categories: Interaction, equipment, teaching methodology, instructor technology training, and student orientation provided ample detail from which to inform practice regarding recommendations for reinvention (modification) of VC technology during the implementation stage of Rogers’ five stages of the innovation-decision model. These modifications could assist the college in gaining parity between the two nursing sites, which reported an 18.53 percentage point difference in first time pass rates on the NCLEX-RN exam reported by the Florida Department of Health (Florida Health, 2015).

Examining Health Information Technology Implementations: Case of the Patient-Centered Medical HomeBehkami, Nima A. 01 January 2012 (has links)
It has been shown that the use of Health Information Technology (HIT) is associated with reduced cost and increased quality of care. This dissertation examined the use of registries in Patient Centered Medical Home (PCMH) practices. A survey questionnaire was sent to a nationwide group of clinics certified for being a PCMH. They were asked to provide information about their payer mix, implementation barriers, registry implementation, registry use, and clinic satisfaction. The survey instrument was validated by an expert panel which included practitioners and researchers. Statistical methods including Structural Equation Modeling were used for analysis and to test the research hypotheses. The majority of medical home practices that responded used some type of computerized registry, either with basic patient information or integrated with detailed clinical information. And on average, they somewhat used registries for population management, individual health management, proactive care and planned care visits. All practices encountered some combination of barriers when implementing a medical home program. Most practices reported clinic satisfaction at least improved after becoming a medical home. The results of the analysis show that indeed payer mix, in particular Medicare and private insurance, has a significant relationship with level of registry implementation. There were no significant relationships between barriers and registry implementation or use. More sophisticated registry implementation led to greater registry use. And registry use is associated with increased clinic satisfaction. This research fills an important gap in understanding Health IT use, registries in particular, among Patient-Centered Medical Homes. The findings suggest that: 1) Implementation barriers may not be influencing use of computerized registries in medical home practices; 2) Using more sophisticated computerized registries facilitates registry use, which can help improve clinic satisfaction; 3) Payer mix may influence use of more sophisticated Health IT in medical home practices.
