A presente pesquisa visa investigar o envolvimento do usuário final no desenvolvimento de um Sistema de Informação (SI) e sua influência na adoção do SI. Para tanto, realizou-se uma revisão sistemática, em que foram analisados 133 artigos e cujo resultado é a proposição de uma modificação do Modelo de Aceitação de Tecnologia (TAM) incluindo variáveis relativas ao envolvimento do usuário: situacional e intrínseco. Em seguida, foi realizado o teste do modelo proposto a partir de uma survey com 114 respondentes, cujos dados foram analisados através de Análise Fatorial Exploratória (EFA), Análise Fatorial Confirmatória (CFA) e Modelagem por Equações Estruturais (SEM). O teste permitiu inferir que as hipóteses suscitadas estavam corretas e que o envolvimento do usuário é significativo dentro do contexto de adoção de um SI. Por fim, realizou-se um projeto de experimentos fatorial (DOE) fracionado para verificar de que forma envolvimento situacional e intrínseco estão relacionados Evidenciou-se que a composição do efeito de fatores principais e de interações duplas das atividades do envolvimento situacional explica até 57% da variação do envolvimento intrínseco. As principais contribuições teóricas da dissertação versam sobre a consistência aportada pelos métodos utilizados. O subsídio teórico aportado pela revisão sistemática permitiu elaborar relações teóricas com segurança. A utilização conjunta de EFA e CFA é indicada para conferir robustez à pesquisa. Da mesma forma, a modelagem por equações estruturais apresentou utilidade no contexto da pesquisa, embora se indique cuidado ao realizar as modificações no modelo para que se adeque aos parâmetros de qualidade da análise. Por fim, a realização de um projeto de experimento fatorial fracionado é algo incomum na literatura de adoção de SI, mas foi útil para verificação da qualidade da interação entre os tipos de envolvimento, bem como a verificação de quais fatores devem ser evitados. / The present research aims to understand the end user involvement in the Information System (IS) development influence in IS adoption by proposing and testing a specific theoretical model. A systematic review was carried out in which 133 articles were analyzed and its result is a Technology Acceptance Model (TAM) modification proposition. This model includes variables related to the user's involvement: situational involvement and intrinsic involvement. Afterwards, the test of the proposed model was carried out from a survey with 114 respondents, whose data were analyzed through Exploratory Factor Analysis (EFA), Confirmatory Factor Analysis (CFA) and Structural Equation Modeling (SEM). The test allowed inferring that the hypotheses raised were correct and that user involvement is significant within IS adoption context. Finally, a fractional factorial design of experiments (DOE) with seven factors was done to verify how two types of involvement are related. It was evidenced that the composition of the effect of situational involvement major factors and double interactions explains up to 57% of intrinsic involvement variation The main theoretical contributions of the dissertation are about the consistency provided by the methods used. The theoretical subsidy provided by the systematic review allowed development of theoretical relations with safety. The combined EFA and CFA use is strongly indicated to give robustness to the research. Likewise, SEM presented significant utility in research context, although it is indicated caution when making model modifications to fit analysis quality parameters. Finally, fractional factorial DOE with seven factors is uncommon in the literature, but it was extra useful to verify interaction quality between types of involvement.

Artificiell intelligens sprider sig allt mer och mer inom olika arbetsområden. I denna studie har en kvalitativ fallstudie gjorts som behandlar hur sjuksköterskors uppfattning av framtida användandet av AI inom vården kan se ut. Genom att intervjua tre sjuksköterskor, en e-hälsostrateg och en projektledare inom området analyseras även detta empiriska material med hjälp av TAM för att slutligen ta reda på hur sjuksköterskors attityder kring att använda AI i framtiden ser ut. Resultatet av studien visar att sjuksköterskors uppfattning och acceptans av AI inom vården är delad i två områden där ena är icke-beslutsfattande AI och andra, beslutsfattande AI. Resultatet visar alltså hur sjuksköterskors attityd är positiv när det kommer till icke-beslutsfattande AI och mer negativ vid beslutsfattande AI. Detta då sjuksköterskorna anser att den mänskliga kontakten försvinner vid beslutsfattande AI. Det vill säga vid användning av AI-baserade system som behåller patientkontakt och kan besluta om vilken slags vård patienten behöver. Istället menar respondenterna att maskin och människa går bäst hand i hand.

A computação em nuvem emerge quando se trata da necessidade dos desenvolvedores de TI de sempre aumentar ou incluir novas capacidades, o mais rápido possível, com o menor investimento possível. Ela vem sendo apontada como uma das maiores inovações em TI nos últimos anos e por isso vem chamando a atenção tanto da comunidade acadêmica quanto da comercial. Apesar deste crescente interesse na tecnologia pela literatura acadêmica, a maior parte do foco das pesquisas se dá nos aspectos técnicos, como potencial computacional e custos. Pesquisas sobre as preferências dos profissionais da área relativa à computação em nuvem como uma ferramenta de negócios estão limitadas a estudos de consultorias e empresas privadas. Esta pesquisa tem como objetivo apresentar um estudo do impacto de diferentes dimensões sobre a intenção de adoção da computação em nuvem por profissionais de TI. Para isto, utiliza uma variação do modelo TAM/UTAUT para verificação de intenção de adoção de novas tecnologias. O método escolhido foi a pesquisa survey, realizada a partir de um instrumento previamente proposto e adaptado, sendo feita em duas etapas: estudo de pré-teste e estudo final. Diferentes técnicas estatísticas foram empregadas para refinar o instrumento, como Análise de Confiabilidade, Análise Fatorial Exploratória e Análise Fatorial Confirmatória, utilizando o método PLS (Partial Least Squares) para Equações Estruturais. Como resultado deste refinamento emergiu um modelo teórico de pesquisa final contendo 8 dimensões e 36 itens. Como contribuição para a área de SI, o modelo teórico de pesquisa final se mostrou adequado para avaliar a intenção de adoção da computação em nuvem por profissionais de TI. A principal contribuição da pesquisa para a prática gerencial é o modelo de intenção de adoção da computação em nuvem, que pode auxiliar provedores de computação em nuvem, através da mensuração das principais razões para sua adoção, que são Utilidade Percebida e Atitude Frente à Inovação Tecnológica. Também demonstra que não existe uma relação positiva entre Segurança e Confiança e a Intenção Comportamental. Doze hipóteses foram validadas e seis das hipóteses propostas foram negadas pelos dados. Estas informações buscam fornecer material para que se possa inspirar os esforços no desenvolvimento da tecnologia como ferramenta de negócio. / Cloud computing emerges when we talk about the necessity of the IT developers to always increase or add new capabilities, as soon as possible, with the lowest investment possible. It has been appointed as one of the biggest IT innovations in the recent years, and for that reason it’s been calling the attention of the academic and management communities. Even with the growing interest by the academic community, most of the research focus on technical aspects, such as computational potencial and costs. Researches involving professionals’ preferences with cloud computing as a business tool are limited to consultant and private studies at most. This research has the purpose of presenting a study about the impact of different dimensions in the intention of adoption of cloud computing by IT professionals. To do so, it uses a variation of the TAM/UTAUT model for the verification of the intention of adopting new technologies. The research method is the survey research, made with a previously proposed and adapted instrument, conducted in two stages: pre-test study and final study. Different statistical techniques were used to refine the instrument, such as Reliability Analisis, Exploratory Factor Analysis and Confirmatory Factor Analysis, this one using the PLS (Partial Least Squares) Path modeling for SEM (Structural Equation Modeling). As a result of this refinement, emerged a theorical research model containing 8 dimensions and 36 measuring items. As contribution to the IS area, the theorical model proved adequate to assess the intention of adoption of cloud computing by IT professionals. The research’s main contribution to the business practice is the model of cloud computing intention of adoption, that aids cloud providers, trought the measurement of the main reasons behind the adoption of the technology, wich are Perceived Utility and Attitude Towards Technology Innovation. Also demonstrates that there are no positive relation between Security and Trust and the Behaviorial Intention. Twelve of the hypothesis were sustained, and six of the proposed hypothesis were denied by the data. This information intends to inspire efforts in developing the technology as a business tool.

Introduction: Along with the swift spread of 3G and wireless network, wireless technologies are applied in many areas, especially in education. The advent of mobile learning overcomes several limitations and barriers of traditional classroom education. As for higher education in China, mobile learning is in its infancy stage. Understanding end-users’ acceptance of mobile learning is crucial, because new technological advances cannot enhance performance if they are not accepted by end-users. This study focuses on three top Chinese universities and answers the following research questions: How do students perceive mobile devices as a learning tool incorporated in class and what are their attitudes towards mobile learning? What are the motivational factors that affect students’ acceptance of mobile learning? Purpose: The purpose of this study is to test the proposed Technology Acceptance Model (TAM) in explaining students’ acceptance in three top Chinese universities. The goal of this work is to enhance the understanding of user acceptance of incorporating learning into mobile device inside and outside classes. Method: A deductive, theory-testing approach was used in this study. Eleven hypotheses were built based on a literature review and on the proposed TAM model, and were tested using primary data and literature review. Primary data was gathered via semi-structured interviews and questionnaires. The data collected through the questionnaire was analysed by Structural Equation Modeling. Conclusion: Through testing the proposed model, the authors found that students are positive towards mobile learning but they do not have a strong willingness to adopt it. The proposed TAM model can improve the understanding of students’ motivation by suggesting what factors are the most important in enhancing students acceptance of mobile learning.

Context: Researchers in serious games area and professionals in stroke rehabilitation, working collaboratively in explorative interdisciplinary research studies in order to develop usable and effective applications. In this context, physiotherapists and occupational therapy are important elements of stroke rehabilitation. Applications from such exploratory development reflect motivational and easy to use features, which could be further designed and developed by serious games developers. Objectives: The research study aims to investigate the role and usefulness of Video Capture Virtual Reality Technology (VCVRT) in motor impairment rehabilitation, to identify and explore the importance of this technology in healthcare, specifically in motor impairment rehabilitation. Likewise, to analyze the acceptance of VCVRT among the physiotherapists in terms of perceived ease of use, perceived usefulness and perceived intension to use. Methods: In this exploratory study literature review, workshop and survey including questionnaire and interview are used, taking Blekinge County Hospital (Karlshamn) as case study along with “TARGET” game as testing platform for introducing and evaluating VCVRT among physiotherapists. For exploring technology acceptance level among physiotherapists, Technology Acceptance Model (TAM) was used in the research work. Results: Video capture virtual reality technology can be used as a complement to conventional physiotherapy. This technology is cheap, easy to use and is useful as a home based rehabilitation tool, but together with physiotherapist supervision or coaching. Moreover, VCVRT is motivational for weak patients and useful in motor rehabilitation in terms of quantity, i.e. intensity of exercise can be increased. Physiotherapist centered approach is necessary for game design process; effective game design suggestions and the idea of single gaming framework consists of different games acquiring multiple rehabilitation goals, are achieved from physiotherapists during the research. Technology acceptance value is high among physiotherapists. Conclusion: The research study provides a more detailed understanding of the factors involved in the implication of video capture virtual reality technology in motor impairment rehabilitation. The authors concluded from the research study that video capture virtual reality technology is applicable for motor impairment rehabilitation while considering following factors, i.e. Physiotherapist centered approach, a gaming framework where a portfolio of games can be assembled for individual patients, and video capture virtual reality technology is applicable for home based rehabilitation under the supervision of physiotherapist. Furthermore, physiotherapists’ concerns and importance in the intervention of serious games and healthcare area are highlighted by this research work.

As a result of covid-19, there has been an increase of digitalisation in society and remote-work has therefore also increased. Workplaces have sent employees home and meetings have taken place through video calls over the internet. Remote-work is not evenly distributed across different occupational groups, but within financial institutions, the majority of work can be performed in an independent location. The purpose of this paper is to gain an increased understanding of the experience of usability within digital conference tools. This paper examines the perceived usefulness of conference tools by applying the theories Technology Acceptance Model (TAM) and Theory of Reasoned Action (TRA). This paper uses both a questionnaire and interviews to answer the research question. The result indicates that the experience of usability has a TAM score of 75,39 for the total average at financial institutions. One difference that the study found was the experience of usability based on the length of time the employee has used Microsoft Teams at financial institutions, the less time of use, the lower the score. This means that there may be a learning need of Microsoft Teams. Positive experiences for Microsoft Teams perceived usability, which can be generalized to more conference tools, are time-saving, efficient and good functionality. Negative experiences for Microsoft Teams perceived usability, which also can be generalized to more conference tools, are file management, resource-heavy and impersonal.

Student technology literacy is critical for success in today’s world; however, little is understood about how teachers make the decision for students to use technology for learning due to limited empirical research on the topic of teacher decision-making regarding student use of information communication technologies (ICT). The purpose of this generic qualitative study was to explore the decision-making process of kindergarten to Grade 5 (K-5) teachers regarding implementation of ICT for student use at varying levels. The framework for this study comprised the substitution augmentation modification redefinition model and the technology acceptance model. The research questions focused on how teachers have students use technology in the classroom, the influences on teacher decision-making to have students use technology, and how decision-making compared among K-5 teachers whose students use technology at varying levels of implementation. Interview data were collected from 12 teachers at a public-school district in the southern United States that were analyzed using 2 cycles of coding: a priori and emergent. Key findings were that (a) teachers have students use technology primarily at substitution and augmentation levels, (b) teacher decisions were influenced mostly by student technology readiness, and (c) teachers who used technology at redefinition levels had different factors for decision-making. The results of this study may contribute to positive social change by creating a deeper understanding of the decision-making process of teachers, which can positively affect student engagement, academic growth, and lay the foundations for technology literacy for students.

The introduction of new information systems in different types of organizations is becoming more and more frequent in today's modern and digitized society. A common problem is that the new systems fail to reach user popularity. It is therefore important to ensure that the new systems that are introduced are accepted by the users. The study examines which factors are most important for teachers and course administrators at Uppsala University when they start using a new digital exam system - Inspera Assessment. The survey was conducted by collecting qualitative data through interviews of system administrators, teachers and course administrators at Uppsala University. The data generated was then analyzed on the basis of the theoretical framework technology acceptance model 2 in order to identify the factors that are most important to the users for them to accept the new system. In the conclusion, we discuss further how Uppsala University has worked with user acceptance in order to advise on how future implementations can learn from the implementation of Inspera Assessment to ensure high user acceptance. The study concluded that it is important to offer solid support that corresponds to users’ requirements and desires, to take into account the intended users' work processes at new introductions and that users can see a link between use of the system and increased efficiency in the work.
