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.

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.

New technologies are constantly introduced in our everyday life. Societies and people have reaped great benefits from integrating information technology into a plethora of societal and commercial functions. However, innovations are not unconditionally accepted by users. Since digital innovations constantly are introduced to aid us, there is an interest in understanding what factors would either influence us or make us prone to adopt new technologies. The main research question is to identify the key influences, both positive and negative, within technology adoption. The scope was limited to Scandinavian supermarkets and the technology of adoption intention was the Smart Cart; a seamless approach to make your shopping experience easier. Through a value-based acceptance model (VAM), a quantitative survey was conducted to explore consumers, attitudes towards Smart Cart through the factors perceived usefulness (PU), perceived enjoyment (PE), perceived privacy risk (PPR) and perceived difficulty to use (PDU), in relation to the perceived value (PV) of the product which can eventually lead to intention to adopt and use(IAU). The findings showed that perceived usefulness (PU) and perceived enjoyment (PE) demonstrated a strong positive correlation to potential users’ perceived value (PV) of Smart Cart while perceived privacy risk (PPR) showed a weak negative and perceived difficulty to use (PDU) showed a medium-strong positive correlation to potential consumers’ perceived value (PV) of the product. Potential consumers’ perception of Smart Cart’s value (PV) showed a strong positive correlation with intention to adopt and use (IAU).

In the past several years, police-community relations have received enormous scrutiny based on several high-profile incidents involving the use of deadly force. Politicians, civil societies, and victims' families have called for law enforcement agencies to equip local officers with body-worn cameras to increase transparency and accountability. The purpose of the study was to investigate how law enforcement officers in a Sheriff's office in the Southern United States perceived ease of use and usefulness of body-worn camera technology and to identify if gender and years of service related to police officers' acceptance of body-worn cameras as a component of their regular uniform. The theoretical foundation for this study was based on the Technology Acceptance Model (TAM) developed by Davis in 1989. Paper survey using TAM instrument was used to collect data from officers at the training center. A hierarchical multiple regression analysis was conducted to determine which independent variables predicted the frequency of use of body-worn cameras. Analysis of data collected from 88 officers found that their perceptions of the ease of use of body-worn cameras were moderately and positively correlated with their perceptions of the cameras' usefulness and their attitudes toward the camera. The relationship between usefulness and years of service was negative, indicating that as officers' length of service increased, their perceptions of body-worn cameras usefulness decreased. However, officers' attitudes toward using body-worn cameras were a predictor of their reported frequency of use. Findings from the study could contribute to positive social change by providing policymakers with new tools to craft training policies to enhance police-community relations.

Background: To ensure a sustainable future in the maritime industry; new measures of employee well-being are needed. Digital health solutions have proven to possess great potential to ensure employee well-being regardless of location, with opportunities for a proactive instead of a reactive approach where health and safety issues can be avoided.  Research Problem: Despite the potential benefits of using digital health solutions, the acceptance and impact of such solutions remain unexplored in the maritime industry, which is essential for achieving improvements.   Purpose: This study aims to explore what influences the acceptance of digital health solutions for improving seafarer well-being to understand how the maritime industry accepts digital health solutions and, more importantly, the potential impact this acceptance has on seafarer well-being. Research Question: How does the acceptance of digital health solutions in the maritime industry impact the employee well-being of seafarers?  Methodology and Method: This is a qualitative and inductive study, with a relativist view of reality and a social constructionist view of knowledge, that aims to build new theories through semi-structured interviews and Gioia’s analysis method.  Conclusion: Our findings focus on what influences the acceptance of digital health solutions and how these solutions impact employee well-being. With the aid of the Technology Acceptance Model (TAM), we find that there are levels of acceptance dependent on the nature of different influential factors. Furthermore, we discover that digital health solutions can influence physical, mental, and social well-being. From this, we develop a framework explaining the impact acceptance has on employee well-being. As a result, we illustrate that acceptance is a crucial aspect of improving employee well-being with digital health solutions.

Bakgrund och syfte: Antalet tekniska system som människor använder i vardagen ökar ständigt. När en användare byter från ett tekniskt system till ett annat som hen inte är bekant med, kan det uppstå problem eller i vissa fall gå smidigare än förväntat. Syftet med denna studie är att undersöka hur väl användares mentala modell av ett operativsystem kan appliceras på ett annat, för användaren outforskat, operativsystem. Studien undersöker också huruvida användarens acceptans av ny teknik är associerad med dennes prestationer i det nya operativsystemet. Metod: Studien baseras på ett experiment där åtta testdeltagare med erfarenhet av Microsoft Windows genomför vardagliga uppgifter i Apple MacOS och vice versa. Gruppernas förmåga att anpassa sina mentala modeller mäts med hjälp av prestationsmått som vanligtvis används inom interaktionsdesign, såsom tidtagning och antalet steg som krävs för att genomföra varje uppgift. En enkät används därefter för att mäta deltagarnas acceptans av ny teknik med hjälp av TAM (Technology Acceptance Model). Resultat: Resultaten visade en signifikant skillnad mellan grupperna när det gällde prestationsmåtten. MacOS-användare hade kortare tid och färre steg för att genomföra uppgifterna jämfört med Windows-användare. Studien fann även en signifikant negativ korrelation mellan acceptans av ny teknik och tid som krävdes för att genomföra uppgifterna. Ingen signifikant korrelation fanns mellan acceptans av ny teknik och antalet steg att genomföra uppgifter. Slutsatser: MacOS-användares mentala modell är mer överförbar till Windows, än vad Windows-användarnas mentala modell är till MacOS. MacOS-användares mentala modell passar tillräckligt bra för att kunna appliceras på Windows för att genomföra vardagliga uppgifter utan större problem. Windows-användarnas mentala modell är så pass annorlunda att en ny mental modell skapas när de ger sig på MacOS, vilket leder till längre tid och fler steg att genomföra uppgifter. Studien fann också att användare med en hög acceptans av ny teknik presterade bättre, i form av lägre tid, när de använde ett outforskat operativsystem. Detta kan dock tolkas på två sätt, att användare som snabbt kunde genomföra uppgifter i större utsträckning uppskattade det, vilket ledde till en högre acceptans av ny teknik. Alternativt att deltagare som generellt var öppna till ny teknik därför presterade bättre. Däremot upptäcktes ingen stark koppling mellan acceptans av ny teknik och antalet steg som krävdes för att slutföra uppgiften. Detta gör att det inte går kan dra några definitiva slutsatser om kopplingen mellan acceptans av ny teknik och övergripande prestation, då endast en del av prestationen (tid, men inte antalet steg) visade signifikanta resultat.

This phenomenological study explored and described the lived experiences of high school biology teachers from a school district in one of the states in the USA concerning the use of online platforms in online biology teaching and learning during the COVID-19 pandemic. The study interviewed teachers to evaluate the teacher experiences, challenges, and opportunities that online platforms presented in biology instruction during the COVID-19 pandemic. The study also analyzed students' perspectives based on the teachers' responses and district data obtained from the student engagement survey administered to all high school students at the school district every year. The findings of the study indicate that students experienced issues such as lack of engagement, unsuitable home environment to support learning, and poor attendance due to minimal monitoring when learning shifted to fully online. Teacher-related factors included inadequate preparedness to use technology to enhance teaching, limited content delivery, and increased teacher collaboration. In conclusion, the study recommends that school districts sufficiently prepare teachers to improve adaptability to different teaching and learning models, emphasizing the use of diverse educational technologies. Future studies should conduct quantitative or mixed studies to establish the extent and degree to which such factors as poor learner engagement contributed to less than satisfactory outcomes in summative and formative assessments.

Majoriteten av alla utvecklade informationssystem misslyckas. Detta beror på olika faktorer, där otillräcklig användarinvolvering och användaracceptans under utvecklingen är den vanligaste orsaken. Technology Acceptance Model – TAM är en teoretisk modell som studerar användaracceptans och de faktorer som påverkar användaracceptans av ett informationssystem. Denna studie har använt den kvalitativa forskningsmetoden för att testa användningen av TAM vid utvecklingen av ett ärendehanteringssystem hos en offentlig myndighet. Resultatet av denna studie påvisar fördelar med att använda TAM vid utvecklingen av ett informationssystem och att användningen av modellen kan bidra till att utvecklingen av ett informationssystem kan utformas med användarnas preferenser i fokus och på så sätt undvika att användarna inte upplever ärendehanteringssystem som användarvänligt och användbart. Resultaten från denna studie visar också att de identifierade TAM-faktorerna överensstämmer till stor del med befintlig forskning. Samtidigt ger denna studie en mycket djupare förståelse för faktorer som påverkar användaracceptans för ett ärendehanteringssystem för en offentlig myndighet. Framtida forskning bör fokusera på att utvärdera användningen av TAM i början av systemutvecklingsprojektet istället för i slutet när informationssystemet har utvecklats och på att använda TAM för att utvärdera användaracceptans av ärendehanteringssystem som inkluderar både interna och externa användare. / <p>Det finns övrigt digitalt material (t.ex. film-, bild- eller ljudfiler) eller modeller/artefakter tillhörande examensarbetet som ska skickas till arkivet.</p><p>There are other digital material (eg film, image or audio files) or models/artifacts that belongs to the thesis and need to be archived.</p>
