This topic has become relevant to organizations since it is a potential problem, which may affect the organizations competitiveness, amongst other reasons. It is believed that some of the individuals who have turnover intention look for means of communication, new technologies, such as the professional social network LinkedIn, in order to spread their professional information, find professional opportunities by networking, as well as obtain more information about the labor market, besides different other functions. Therefore, the turnover intention may be considered as a previous factor to the individual adoption of the professional social network LinkedIn. This study has analyzed the previous factors that may influence the usage and how they use the professional social network LinkedIn, guided by the theoretical perspective of the Unified Theory of Acceptance and Use of Technology (UTAUT), by Venkatesh et al (2003), and also guided by the scale of the turnover intention, by Siqueira et al (2014)and Van Dam (2008). The research is based on a quantitative investigation approach, in which data collection was done using a research tool, and obtained 292 answered questionnaires, which has made it possible to validate the relations between the constructs of the research model developed for the study of the individual adoption of the professional social network LinkedIn. There was an analysis of structural equations to make the test of the study hypotheses, based on PLS-PM (Partial Least Squares Path Modeling) from which satisfactory measures for all the investigated constructs and proposed models were presented, and all the relations between the constructs were significant. The results obtained by this study confirm the influence of previous factors, such as Performance Expectancy, Effort Expectancy, Social Influence, and Turnover Intention, on the intention of using the professional social network LinkedIn. The study concludes that the Performance Expectancy was revealed to be the greatest influence in the intention of using LinkedIn, since there is the perception that by using it, it is possible to obtain some professional benefits as well as other aspects. The second factor to present the greatest influence was the Turnover Intention, once some individuals, by adopting LinkedIn, may tend to show it to other people or organizations that are interested in their talents, experiences, skills, network and so on. The Effort Expectancy, in turn, showed that some individuals notice it is easy to interact with such technology, and the Social Influence showed that there is the individuals perception as to the influence of their network in their intention of using LinkedIn. / A intenção de rotatividade refere-se à probabilidade de os indivíduos deixarem o seu trabalho atual. Este tema se tornou relevante para as organizações por ser um potencial problema que pode afetar a competitividade das organizações, entre outros motivos. Acredita-se que alguns dos indivíduos com intenção de rotatividade possivelmente buscam meios de comunicação, novas tecnologias, como a rede social profissional LinkedIn objetivando disseminar suas informações profissionais, localizar oportunidades profissionais, obter mais contatos e informações sobre o mercado de trabalho, entre outras possibilidades. Desse modo, a intenção de rotatividade pode ser avaliada como um fator antecedente à adoção individual da rede social profissional LinkedIn. Este estudo analisou os fatores antecedentes que podem influenciar a intenção de uso e o comportamento de uso da rede social profissional LinkedIn, apoiando-se na perspectiva teórica da Teoria Unificada de Aceitação e Uso da Tecnologia (UTAUT), de Venkatesh et al (2003), e na escala de intenção de rotatividade, de Siqueira et al (2014) e Van Dam (2008). A pesquisa fundamenta-se em uma abordagem de investigação quantitativa na qual os dados foram coletados por meio de um instrumento de pesquisa com a obtenção de 292 questionários respondidos, o que possibilitou a validação dos relacionamentos entre os construtos componentes do modelo de pesquisa desenvolvido para o estudo da adoção individual da rede social profissional LinkedIn. Para realizar o teste das hipóteses do estudo, procedeu-se a análise de equações estruturais, com base no PLS-PM (Partial Least Squares Path Modeling) a partir do qual foram apresentadas medidas satisfatórias para os construtos investigados e o modelo proposto, sendo significativas todas as relações entre os construtos. Os resultados obtidos por esta pesquisa confirmam a influência dos fatores antecedentes Expectativa de Desempenho, Expectativa de Esforço, Influência Social e Intenção de Rotatividade na intenção de uso da rede social profissional LinkedIn. O estudo concluiu que Expectativa de Desempenho revelou-se o fator que mais influencia na intenção de uso do LinkedIn, pois há a percepção de que ao utilizar o LinkedIn pode-se obter benefícios profissionais, entre outros aspectos. O segundo fator que apresentou maior influência na intenção de uso do LinkedIn foi a intenção de rotatividade, uma vez que alguns dos indivíduos, ao adotarem o LinkedIn, provavelmente tendem a mostrar para as outras pessoas/organizações interessadas quais são os seus talentos, suas experiências, competências, além de obter mais contatos, entre outros motivos. Já a Expectativa de Esforço demonstrou que alguns indivíduos percebem que é fácil a interação desta tecnologia. A Influência Social constatou que existe a percepção dos indivíduos quanto à influência da sua rede de contatos na intenção de uso do LinkedIn.

Wearables som teknologi inom träning är ett etablerat koncept och många använder sig av dessa bärbara enheter. Statistik från Världshälsoorganisationen (WHO) visar att 23% av alla vuxna inte är tillräckligt fysiskt aktiva och forskning visar även på att många slutar använda sina wearables. Samtidigt har det gjorts få studier som undersöker dem faktorer som får användarna att acceptera teknologin. Denna studie kommer med utgångspunkt i UTAUT-modellens konstrukt och demografiska variabler, studera svenskatalande användares acceptans av deras wearable i träning. Den data som studien bygger på samlades in genom en surveyundersökning och analyserades med statistiska metoder. Resultatet av den kvantitativa studien påvisade att intentionen till att använda en wearable i träning har störst påverkan på den faktiska användningen. Intentionen påverkas främst av förväntad prestanda. / Wearable fitness technology is a well known concept, with plenty of users. Statististics from the WorldHealthOrganization show that 23% of all adults do not exercise enough. Other studies have shown that many users stop using their wearable devices, as well as the fact that earlier studies have not focused on explaining acceptance and intention to use wearables in fitness. Following study is based on the constructs and moderating variables of the UTAUT-model and implies to investigate wearables acceptance in fitness of swedish speaking people. The data was gathered by a survey and was analysed using statistical methods. We found that Behavioral intention explained Use behaviour, and the intention to use wearable in fitness was mostly affected by Performance Expectancy.

Organizations that adopt digital innovations are facing a digital transformation, which can cause complications if not implemented in a systematic and methodical way. Due to Covid-19 organizations have had to adapt their work structure to enable personal to work from home to ensure the health of staff and customers. Covid-19 also forced organizations to accelerate their digital transformation which have led to a stressful implementation of new technology. An accelerated transformation can result in minimal effects which in turn results in failure and the organization can suffer the loss of assets, skills, and income. This case study aims to investigate how an organization in the Swedish bakery market has handled an accelerated digital transformation due to external pressure from Covid-19. Also, the study aims to investigate which relationship in the model T-O-E has the greatest impact on the organization’s technology adaptation. Seven hypotheses and one null hypothesis were generated based on theory and previous research. To answer these, a web-based quantitative survey was conducted consisting of 59 questions, measuring 18-character traits, which in turn examine five dimensions, (1) the digital transformation process, (2) individual impediments, (3) the organization’s obstacles and opportunities as well as the competence and incompetence imbedded in the organization, (4) perceived usability and user-friendliness and (5) Covid-19. The questionnaire was then analysed to find mean, standard deviation, percentage, and correlation. The result show that the company has successfully accomplished the transformation and this despite that all theory goes against this accomplishment, and sates that an accelerated digital transformation would result in failure. Furthermore, the result show that external pressures (in this case Covid-19) in T-O-E had the greatest impact on the organization's success and was the reason that the implementation succeeded without major complications. It turned out that the degree of complexity of the technology played a big role in the company's success. Because if the technology had maintained a greater degree of complexity, the company would probably not have been as successful. In conclusion, the factor Organization played a crucial role in the adoption of the technology, because the management despite a forced accelerated digital transformation managed to generate a smart leadership and an ideal culture, that caused most of the staff to experience the transformation positively. The study shows that companies do not need strategic analysis to be successful in a transformation, but on the other hand, a threefold symbiosis of technology, organization & Covid-19 is required to succeed with a forced accelerated transformation. / Organisationer som anammar digitala innovationer står inför en digital transformering, vilket kan ge upphov till komplikationer om det inte införs på ett systematiskt och metodiskt sätt. På grund av Covid-19 har organisationer fått anpassa sin organisation till arbeta hemifrån, för att säkerställa personalens och kunders hälsa. Detta har lett till att organisationer stressar med transformeringen vilket kan leda till att effekten blir minimal, som i sin tur resulterar i ett misslyckande och organisationen går miste om tillgångar, kompetens och intäkter. Denna studie syftar till att undersöka hur en organisation inom den svenska bagerimarknaden har hanterat en accelererad digital transformering på grund externa påtryckningar från Covid-19 och till att undersöka vilket förhållande i modellen T-O-E (technology-organization-environment) som har störst inverkan på organisationens framgång i transformationen. För att uppnå syftet skapades sju hypoteser och en nollhypotes utifrån teori och tidigare forskning. För att besvara dessa hypoteser och samla in data genomfördes en webbaserad kvantitativ enkät som bestod av 59 frågor, som mäter 18 karaktärsdrag, som i sin tur undersöker fem dimensioner, (1) den digitala transformeringsprocessen, (2) individuella mot-och medgångar, (3) organisationens hinder och möjligheter samt kompetens och inkompetens, (4) upplevd användbarhet och användarvänlighet och (5) Covid-19. Sedan analyserades enkäten för att hitta medelvärden, standardavvikelser, procentsatser och samvariationer. Resultatet visar att företaget har på ett framgångsrikt sätt lyckats med transformeringen och detta trots att all teori tyder på att en accelererad digital transformering inte skulle uppnå önskvärda resultat. Vidare visar resultatet att externa påtryckningar (i detta fall Covid-19) i T-O-E hade störst inverkan på organisationens framgång och medförde att implementeringen genomfördes utan större komplikationer. Det visade sig att teknikens grad av komplexitet spelade en stor roll i företagets framgång. Detta eftersom om tekniken hade erhållit en större grad av komplexitet hade troligen företaget inte varit lika framgångsrikt. Avslutningsvis spelade faktorn organisation en avgörande roll i adoptionen av tekniken, eftersom ledningen trots en påtvingad accelererad digital transformering lyckades generera ett smart ledarskap och en idealisk kultur som medförde att majoriteten av personalen upplevde transformeringen positiv. Studien visar att företag inte behöver strategiska analyser för att vara framgångsrika i en transformering men däremot krävs det en trefaldig symbios av teknologi, organisation & Covid-19 för att lyckas med en påtvingad accelererad transformering.

Podcasting被譽為繼Blog之後最受歡迎的個人化媒介，具備了RSS、可攜性、個人隨選性、內容草根性等特性，在全世界已經帶起一股風潮，尤其在美國更是受到極大的重視與歡迎，而Podcasting在台灣未來的發展又會如何呢？任何新科技的發展都必須回歸到使用者身上來討論，因此，本研究欲探討影響目前使用者採用Podcasting因素與使用行為。Podcasting的使用行為主要包含兩類型，一為下載收聽Podcast，二為自行製播Podcast。因為目前純粹下載收聽Podcast的使用者為多數，因此本研究以此族群為主要研究對象。 本文主要援引UTAUT理論加上「認知有趣性」與「PIIT」兩構面，試圖形成更完善的解釋模型，進行量化研究。此外，輔以深入訪談方法，以了解Podcaster(又稱播客)製作經驗以及對Podcasting發展的看法，豐富量化研究之討論，並歸結出台灣發展Podcasting的優勢與劣勢，以及對Podcasting未來推廣之方向與建議。研究發現影響使用者採用Podcasting最重要的原因就是「認知有趣性」，如果使用者在收聽Podcast過程中得到樂趣，則越會想要去使用。「績效期望」、「PIIT」亦皆正向顯著影響「使用意向」，「社會影響」對於「使用意向」則無顯著影響。而「實際使用行為」方面，「使用意向」為最重要的影響構面，「有利條件」則無顯著影響。此外，從訪談資料中得知，影響使用者收聽行為還包含內容的豐富度、建置完善的節目集散平台，影響使用者製作行為則有個人心態問題、節目製作難易度、是否有合適的頻寬與免費(或便宜)的網路空間、音樂智財權等問題，這些問題亦都是發展Podcasting上重要的關鍵。當然，Podcasting具有極大的發展潛力，未來可朝向相當多元面向的應用。 / Podcasting is known as the most popular personal media while Blog is previously considered the most important personal media. There are many attractive traits of Podcasting including RSS, portability, personal on demand, grassroots content. Podcasting has already become a hot trend in many countries, especially in America. What will be the future of Podcasting in Taiwan? When it comes to the development of new technology, we should go back to the users’ level to find the answers. Thus this paper explores the influential factors of Podcasting users’ acceptance and their behavior. The main objects of the study are the users who only download and listen to Podcasts because they are the majority in Taiwan so far. This paper is based on UTAUT theory adding "Perceived Playfulness" and "PIIT" in an attempt to form a more perfect interpretative model to do quantitative research. To broaden the scope of the whole research, I also adopt in-depth interviews in a qualitative way. Research results show that the most important factor affecting users’ intention is "Perceived Playfulness". Regarding "Use Behavior", "Behavior Intention" is noted as the most significant factor. Based on the information gathered from the interviews, the causes which lead to influence the users’ behavior are the diversity of the content and the maturity of the platforms. What influenced podcasters making podcasts are podcasters’ personality, ease of production process, the availability of suitable bandwidth and free (or cheap) network space, music and other intellectual property issues. All factors mentioned above are important issues in the development of podcasting. Of course, Podcasting has great potential for development so we can expect that there will be multi-oriented applications in the future.

Studien har genomförts med stöd i en kvantitativ enkät om vad som påverkar inställningen till online-utbildning. Genom Unified Theory of Acceptance and Use of Technology (UTAUT) samt tidigare forskning har 5 faktorer valts att undersökas som möjliga faktorer till vad som påverkar inställningen till online-utbildning. Dessa är kön, ålder, attityden till teknologi, upplevd läs- och skrivförmåga samt upplevd autonomi. Av dessa faktorer påvisar framför allt upplevd läs- och skrivförmåga, upplevd autonomi och attityden till teknologi kunna påverka inställningen till online-utbildning. Även ålder tenderar att påverka inställningen till online-utbildning. Ovannämnda faktorer kan anses särskilt viktiga vid arbete med online-utbildningar. Slutsatser av studien är fortsättningsvis uppmärksammandet av en utmaning i att utveckla online-utbildning, som verktyg, till att kunna bidra med samma inlärningsmöjligheter som vid traditionell/klassisk utbildning samt att motivation är ett fält som borde vara väl utforskat vid utformningen av online-utbildning för att maximera lärresultatets möjligheter vid online-utbildning.

Attitudes of users towards new Information Technology products have been the matters of consumer research studies. Factors that affect user behavior in terms of IT acceptance have been modeled by different researchers with an attempt to predict the actual usage. This study aims to analyze these factors and their significance in military context. One of the robust models, namely Unified Theory of Acceptance and Use of Technology (UTAUT) is used as the study model with required modifications in order to augment its compatibility. Therefore an exploratory survey study is conducted within the target user group of two rugged mobile computers with the participation of 37 Turkish sergeants. The study used both qualitative and quantitative instruments. The results showed that, for military products, users acceptance criteria mainly concentrate on the performance of the new product and its relative ease of use.

The e-learning system is one of many educational methods that allow flexible learner-centered education. It is also an information system based on the Internet. Hence, the increasing use of the e-learning has provided an inter-disciplinary research opportunity to information systems and educational engineering fields. But the benefits of an e-learning are subjected to the organization¡¦s learning environments, readiness and the acceptance of self-directed users. In other words, self-directed learning (SDL) is a prerequisite to e-learning success. It is important to evaluate the readiness of self-directed users and their acceptance of e-learning system. This paper focuses on examining the applicability of both the technology acceptance model (TAM) and the Unified Theory of Acceptance and Use of Technology (UTAUT) in explaining adult self-directed users¡¦ acceptance of e-learning system in a blended learning context. The combination of user groups (adult learners), the technology (e-learning system), and the context (blended learning in a higher education institution) is new to IT acceptance researches. The purpose of this research is to shed light on more effective ways to motivate part-time adult learners to use e-learning system in a higher education institution. This study extends both the TAM and UTAUT models with self-directed learning (SDL) concepts. A questionnaire was developed based on previous works in the areas of technology acceptance and SDL. Based on responses from 433 adult blended learners, both SDL-based TAM and UTAUT models were evaluated in terms of overall fit, explanatory power, and their causal links. Overall, findings suggest that TAM may be more appropriate than UTAUT for examining high SDLRS score user group¡¦s e-learning acceptance behaviour; UTAUT may provide e-learning designers and management teams some crucial suggestions to enhance low SDLRS score users¡¦ system utilization. This study also asserts that the successful transition to an e-learning environment requires that the self-directed learners be actively encouraged and supported by their organizations. Results of this study provide reliable and valid SDL-based TAM and UTAUT instruments for organizations to determine whether their learners had the necessary skills for SDL-based blended learning before investing huge budget and time in a large-scale e-learning project. As more organizations experiment with e-learning systems, the SDL-based TAM and UTAUT models could be used to (a) assess the degree of users¡¦ self-directed readiness before e-learning implementation; and (b) evaluate the factors affecting users¡¦ acceptance of new e-learning system and provide useful remedies for improving system utilization rate after e-learning implementation.

With increasing merging of the Internet in our daily lives, online shopping becomes a new consumption model. The study subject was female customers who did shopping online. By means of performance expectancy, effort expectancy and social influence in terms of Unified Theory of Acceptance and Use of Technology (UTAUT) as well as involvement degree, the study explored if those variations had influenced female customers¡¦ intentions and behaviors on online shopping. We issued 240 questionnaires by purposive sampling and analyzed by quantitative statistics. The result shows that performance expectancy, effort expectancy and social influence originating from UTAUT significantly influenced female customers¡¦ intentions. Moreover, their intentions also significantly influenced their behavior online.

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.
