While research supports the integration of mobile computing into instruction, there is disagreement concerning the unstructured use of mobile devices in lecture-based college classrooms. Research supports the argument that unstructured use creates distraction and decreased academic performance. Research also suggests that unstructured use actually supports lecture instruction through personalized learning situations. In either case, the motivations of students to use mobile device is often unclear. This study sought to investigate the motivations for students’ acceptance of mobile devices. The Unified Theory of Acceptance and Use of Technology (UTAUT) was utilized to identify the factors leading to college students’ adoption of mobile devices. A survey based on UTAUT was distributed to 254 college students in six distinct lecture-based general education courses. The results revealed that Performance Expectancy, Effort Expectancy, and Social Influence were positively correlated with Behavioral Intention for class-related behavior, with Performance Expectancy being the most significant. None of the constructs were significant for behavior unrelated to lecture. Analysis of the students’ intention based on the UTAUT moderators of age, gender, and experience did not produce any significant difference, nor did an analysis of the classes by subject. The study concludes that the ability of a mobile device to complete specific tasks was the strongest motivating factor leading to intention.

At public high schools in Cayman, teachers need to improve their productivity and efficiency by using technologies that are simple and portable like their personal devices. Studies about bring your own device (BYOD) initiatives have revealed conflicting outcomes, and are lacking in the Caribbean and especially in Cayman. The purpose of this quantitative study was to determine the main factors related to teachers' willingness to adopt BYOD in public high schools in Cayman. The theoretical framework was the unified theory of acceptance and use of technology (UTAUT). This study employed a cross-sectional survey design using a modified UTAUT instrument, which captured quantitative data from 82 participants. The use of hierarchical multiple regression to analyze the data revealed that teachers' BYOD adoption could expand by increasing facilitating conditions, performance expectancy, effort expectancy, and decreasing perceived risk. This study reduces the gap in the literature about the unified theory of acceptance and use of technology and BYOD in the Caribbean and the Cayman Islands. It also provides evidence that perceived risk can increase its explanatory power of the unified theory of acceptance and use of technology. The study also contributes to a positive social change by revealing critical issues that administrators should address when devising BYOD policies and planning educational technology integration.

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.

Ph. D. (Department of Business Administration, Faculty of Management Sciences), Vaal University of Technology. / The use of technology in supply chain management has increased over the years. Procurement is one of the primary supply chain management areas where the use of technology has gained momentum. This has been realised through the use of e-procurement systems. However, the adoption and implementation of e-procurement can be achieved more effectively if available models of technology adoption are taken into consideration. This study tested a conceptual framework integrating the Technology Acceptance Model (TAM) and the Unified Theory of the Acceptance and use of Technology (UTAUT) in the implementation of e-procurement practices in the South African public sector. Although there are several studies that have focused on procurement in the public sector in South Africa, there is no evidence of studies that extended the use of the TAM and the UTAUT within the public sector in South Africa. This study was conducted to fill this gap by proposing a framework combining the TAM and UTAUT and modelling their role in the adoption of e-procurement in the public sector. The study adopted a survey design and a quantitative research approach was used to evaluate relationships between different variables. The final sample for this study consists of 263 supply chain management (SCM) practitioners drawn from the public sector in the Gauteng Province, South Africa. A self-completion survey questionnaire was used to gather data to measure the eight constructs of the TAM and UTAUT. An Exploratory Factor Analysis (EFA) procedure was performed to assess the factor structure of the data collected in the study. Descriptive statistics were applied to examine the demographic profile of respondents and the perceptions of respondents towards the research constructs. Pearson correlations were used to test relationships and regression analysis was used to test the hypotheses. In the EFA, two new factors, labelled as Personal Competence and External Assistance, were identified. The results of the hypotheses tests showed that five factors, namely: perceived use, self-efficacy, facilitating conditions, personal competence and external assistance significantly predicted attitudes towards the use of e-procurement systems. However, perceived ease of use was statistically insignificant. The results further show that attitudes towards system use significantly predict behavioural intention, which in turn significantly influences actual e-procurement system use. The theoretical framework fusing the TAM and UTAUT models provides useful insights for other researchers and adds valuable knowledge to the factors that might contribute to the adoption of e-procurement in the South African public sector. The study further makes significant contributions to SCM professionals in the public sector. It reiterates the challenges faced in SCM in the public sector and then demonstrates how the adoption of e-procurement could improve the system, while reducing service delivery inequality. By indicating the factors either promoting or impeding the adoption of e-procurement in the public sector, the study provides practitioners and other decision makers in SCM with suggestions on how to facilitate more rapid adoption and circumvent the influence of irrelevant factors. Among other things, the study recommends that to improve the adoption and continued use of e-procurement systems in the public sector in the Gauteng Province, it is necessary to customise the e-procurement system to ensure that it responds to the needs of users. In addition, it is important to increase the confidence and competence of users of the systems, providing the relevant technical infrastructure and support to users in order to positively influence their attitudes and behavioural intention towards the use of e-procurement systems.

L’objectif général de cette recherche doctorale est l’étude des déterminants de l’intégration pédagogique des technologies de l’information et de la communication (TIC) par les professeurs à l’Université de Ouagadougou (UO). Cela nous a conduit à étudier respectivement les compétences technologiques des professeurs, les facteurs de résistance contraignant l’intégration pédagogique des TIC par ces professeurs, l’acceptation et les usages spécifiques des TIC par les professeurs. Ce travail s’est bâti autour des concepts théoriques sur les usages éducatifs des TIC, les compétences technopédagogiques, les facteurs de résistance, l’acceptation des TIC et l’intégration pédagogique des TIC. Ces concepts se sont inscrits dans les cadres d’analyses des modèles d’intégration des TIC par les professeurs et des modèles d’acceptation et d’utilisation d’une nouvelle technologie. La stratégie d’analyse des données s’est construite autour des approches descriptives et analytiques notamment au moyen de l’utilisation de la psychométrie et/ou de l’économétrie des modèles à variables dépendantes limitées. Utilisant la recherche quantitative, le recrutement de 82 professeurs par avis de consentement à participer, a permis de collecter les données sur la base de questionnaires dont la majeure partie est bâtie autour de questions à échelle de Likert. L’étude des compétences technologiques des professeurs a permis d’une part, de dresser un portrait des usages des TIC par les professeurs. En effet, les usages les plus répandus des TIC dans cette université sont les logiciels de bureautique, les logiciels de messagerie électronique et de navigation dans Internet. Elle a aussi permis de faire un portrait des compétences technologiques des professeurs. Ceux-ci utilisent à la fois plusieurs logiciels et reconnaissent l’importance des TIC pour leurs tâches pédagogiques et de recherche même si leur degré de maîtrise perçue sur certaines des applications télématiques reste à des niveaux très bas. Par rapport à certaines compétences comme celles destinées à exploiter les TIC dans des situations de communication et de collaboration et celles destinée à rechercher et à traiter des informations à l’aide des TIC, les niveaux de maîtrise par les professeurs de ces compétences ont été très élevés. Les professeurs ont eu des niveaux de maîtrise très faibles sur les compétences destinées à créer des situations d’apprentissage à l’aide des TIC et sur celles destinées à développer et à diffuser des ressources d’apprentissage à l’aide des TIC malgré la grande importance que ceux-ci ont accordée à ces compétences avancées essentielles pour une intégration efficace et efficiente des TIC à leurs pratiques pédagogiques. L’étude des facteurs de résistance a permis d’ériger une typologie de ces facteurs. Ces facteurs vont des contraintes matérielles et infrastructurelles à celles liées aux compétences informatiques et à des contraintes liées à la motivation et à l’engagement personnel des professeurs, facteurs pouvant susciter des comportements de refus de la technologie. Ces facteurs sont entre autres, la compatibilité des TIC d’avec les tâches pédagogiques et de recherche des professeurs, l’utilité perçue des TIC pour les activités pédagogiques et de recherche, les facilités d’utilisation des TIC et la motivation ou l’engagement personnel des professeurs aux usages des TIC. Il y a aussi les coûts engendrés par l’accès aux TIC et le manque de soutien et d’assistance technique au plan institutionnel qui se sont révelés enfreindre le développement de ces usages parmi les professeurs. Les estimations des déterminants de l’acceptation et des usages éducatifs des TIC par les professeurs ont montré que c’est surtout « l’intention comportementale » d’aller aux TIC des professeurs, « l’expérience d’Internet » qui affectent positivement les usages éducatifs des TIC. Les « conditions de facilitation » qui représentent non seulement la qualité de l’infrastructure technologique, mais aussi l’existence d’un soutien institutionnel aux usages des TIC, ont affecté négativement ces usages. Des éléments de recommandation issus de ce travail s’orientent vers la formation des professeurs sur des compétences précises identifiées, l’amélioration de la qualité de l’infrastructure technologique existante, la création d’un logithèque, la mise en œuvre d’incitations institutionnelles adéquates telles que l’assistance technique régulière aux professeurs, l’allègement des volumes horaires statutaires des professeurs novateurs, la reconnaissance des efforts déjà réalisés par ces novateurs en matière d’usages éducatifs des TIC dans leur institution. / The general objective of this doctoral research is the study of the determinants of the pedagogical integration of information and communication technology (ICT) by teachers at the University of Ouagadougou (UO). This led us to study respectively the technological skills of teachers, the resistance factors forcing the integration of ICT by these teachers together with the driving forces of ICT acceptance and ICT educational uses by teachers at this university. This work is built around theoretical concepts of educational uses of ICT, techno pedagogical competences, factors of resistance to ICT use, acceptance and use of ICT and pedagogical integration of ICT. These concepts are included in frameworks for analysis of ICT integration models by teachers and acceptance and use of new technology models. The strategy of data analysis is built around descriptive and analytical approaches, including the use of psychometrics and / or econometrics models with limited dependent variables. Using quantitative research, the recruitment of 82 professors of this university by a notice of consent to participate to the survey, has allowed collecting data on the basis of questionnaires, most of which being built around Likert scale questions. The study of teachers’ technological skills enables on the one hand, to portray a picture of ICT use by teachers. The most common ICT uses at the University of Ouagadougou are the office software, software for email and Internet browsing. On the other hand, it allows a portrait of teachers’ technological skills. They use many softwares and most of them recognize the importance of ICT to their teaching duties and research, but their degree of perceived control on some of ICT applications remains at very low levels. The teachers presented very high control over the skills to exploit ICT in situations of communication and collaboration and also those intended to seek and process information using ICT. These skills reflect their use of electronic means of communication and search engines and the importance that teachers attach to these ICT applications. Moreover, despite the great importance that teachers give to some advanced skills in ICT, they were found at very low levels of mastery of these skills which are those to create learning situations in using ICT and those intended to develop and disseminate learning resources using ICT. Although teachers already use and combine several applications of ICT, their current level of technology skills and teaching does not allow them to effectively use these technologies in their teaching practices. They must necessarily acquire these essential advanced skills. The study of resistance factors helped to establish a typology of these factors. They range from material and infrastructural constraints to those related to computer skills and the availability of support and technical assistance at the institutional level to promote the use of ICT applications in education. It also assessed the compatibility of ICT with teaching duties and research faculty, the perceived usefulness of ICT for educational activities and research facilities, the motivation and / or personal commitment of teachers to use ICT and the influence of social conditions on such uses. There are also the costs of ICT access (Internet and computer equipment), which have shown a negative influence on teachers and violating the development of these educational uses of ICT. The empirical assessment of determinants of acceptance and educational uses of ICT by teachers reveals that, it is mainly the teachers’ "behavioural intention" to go to ICT and "the Internet experience" that affect positively these uses. The "facilitation conditions" that represent not only the quality of the technological infrastructure, but also the existence of institutional support to use ICT, have negatively affected these practices. The elements that can improve educational uses of ICT in the university have been identified from the results of this research: these recommend the teachers’ training on specific identified skills, the improvement of the quality of the existing technological infrastructure, the creation a software library, the implementation of adequate institutional incentives such as regular technical assistance to teachers, the reduction of statutory hourly volumes to innovative teachers, the recognition of the efforts already made by these innovative educational uses of ICT within their institution.
