This study examined the perceived importance of availability of ICT-based features and technical support on meeting planners' recommendation/selection of a conference center. In addition, this study attempted to explain relationships between meeting planners' beliefs (perceived usefulness and perceived ease of use) toward ICT-based features and other factors: personal innovativeness of ICT (PIICT); perceived importance of the availability of technical support; self efficacy; and result demonstrability. A conceptually integrated and expanded model of the Technology Acceptance Model (TAM) developed by Davis (1986, 1989) was used as a theoretical frame. The subjects of the study were meeting planners who used the selected two conference centers for their meetings or were considering them for their future meetings. A total of 167 usable responses were gathered and the proposed model was empirically examined using the data collected. The results of the model test revealed that the expanded TAM with the integration of key factors provided a systematic view of the meeting planners' beliefs in selection/recommendation of a conference center with ICT-based features. In addition, factor analysis of the fifteen ICT-based features revealed three underlying dimensions based on meeting planners' perceived importance of the availability of each feature for a conference center selection: 1) high-speed wireless Internet; 2) network backbone; and 3) ICT-based service outlet. Specifically, high-speed wireless Internet was the most important ICT-based determinant of a conference center selection/recommendation to all types of meeting planners. Due to the exploratory nature of this study, the results provided limited facets of the impact of ICT-based feature and technical support on meeting facility selection/recommendation. Nevertheless, this study is the first research effort of its kind to investigate what type of ICT-based feature and technical support impact conference center selection/recommendation by different types of meeting planners the most. The results revealed that corporate meeting planners consider wireless Internet and a fast network more important in selection than other types of meeting planners do. The availability of ICT-based features was less important to association meeting planners when they make a conference center selection. This study also identified that there is a serious lack of knowledge in terms related to network backbones across all types of meeting planners. Technical support, especially on-site technical support, was perceived as very important to all types of meeting planners. This study also identified that meeting planners with high PIICT possess stronger confidence in using and visualizing the advantages of ICT-based features. Thus conference centers should make efforts to measure meeting planners' PIICT and use the score effectively for their marketing of ICT-based features. The study also identified result demonstrability—the visualizing of positive outcomes of using ICT-based features—as very important to meeting planners. PIICT and result demonstrability were positively related to perceived ease of use and perceived usefulness which were identified as key antecedents of actual acceptance/usage of technology in previous studies. The results of the current study present an important step toward providing practical as well as theoretical implications for future technology impact studies in the context of meeting facility selection. / Ph.

Indiana University-Purdue University Indianapolis (IUPUI) / Background: Pulmonary rehabilitation (PR) has the potential to reduce the symptoms and complications of respiratory diseases through an interdisciplinary approach. Providing PR services to the increasing number of patients with chronic respiratory diseases challenges the current health care systems because of the shortages in health care practitioners and PR programs. Using telerehabilitation may improve patients’ participation and compliance with PR programs. The purpose of this study was to examine the applicability of the technology acceptance model (TAM) to explain telerehabilitation acceptance and to determine the demographic variables that can influence acceptance. Methods: A cross-sectional survey-based design was utilized in the data collection. The survey scales were based on the TAM. The first group of participants consisted of health care practitioners working in PR programs. The second group of participants included patients attending traditional PR programs. The data collection process started in January 2017 and lasted until May 2017. Results: A total of 222 health care practitioners and 134 patients completed the survey. The results showed that 79% of the health care practitioners and 61.2% of the patients reported positive intention to use telerehabilitation. Regression analyses showed that the TAM was good at predicting telerehabilitation acceptance. Perceived usefulness was a significant predictor of the positive intentions to use telerehabilitation for health care providers (OR: 17.81, p < .01) and for the patients (OR: 6.46, p = .04). The logistic regression outcomes showed that age, experience in rehabilitation, and type of PR increased the power of the TAM to predict the intention to use telerehabilitation among health care practitioners. Age, duration of the disease, and distance from the PR center increased the power of the TAM to predict the intention to use telerehabilitation among patients. Conclusion: This is the first study to develop and validate a psychometric instrument to measure telerehabilitation acceptance among health care practitioners and patients in PR programs. The outcomes of this study will help in understanding the telerehabilitation acceptance. It will help not only to predict future adoption but also to develop appropriate solutions to address the barriers of using telerehabilitation.

This study aims to investigate college students' security awareness of using social media in sharing information. The two theories that have guided this study are the theory of planned behavior (TPB) and the technology acceptance model (TAM). Data was collected from both undergraduate and graduate students from the University of North Texas (UNT) in Denton. The total responses included 380 students from different majors with 291 valid responses for data analysis; The structural equation model (SEM) Lavaan package was used to find out the best fit of the model. A diagonally weighted least squares (DWLS) was used to model the variables as ordinal in this study's analysis as ordinal data made the model fit substantially. The study found that 6 factors: attitude (AB), subjective norm (SN), perceived behavior control (PBC), perceived usefulness (PU), perceived risks (PR), and security awareness (SA) influenced behavior intention (BI). Also, I found that AB was influenced by PR and SA, as well as SN influenced by SA. Self-efficacy (SE) influenced PBC. On the other hand, the study found that controllability (C) did not influence PBC; perhaps, an individual's skills do not interact with social media security settings. Perceived ease of use (PEOU) did not influence BI; perhaps this occurred because of an individual's inability to prevent his or her information from being disclosed in the future, even if they had taken the right precautions. This study contributed to literature on understanding the nature of information sharing among college students on social media. The results may help college security professionals to evaluate or revise the rules and policies regarding cybersecurity and privacy.

Internal marketing and internal communication are essential tools to align em-ployees’ mindsets with the necessary tasks which bring about employee satis-faction and organisational prosperity. Electronic newsletters serve as an internal marketing communication medium which can convey the necessary information to employees regarding the organisation’s goals and objectives. They also act as a medium to build relationships with employees and encourage improved service delivery and customer-oriented employee mindsets. Employees’ willingness to make use of electronic newsletters for the purpose of disseminating organisational information is an indication of employees’ acceptance of the organisational information and use thereof in performing organisational tasks successfully as the organisation intends. The purpose of the current study was to determine employees’ acceptance of electronic newsletters, as an internal marketing communication medium, in order to disseminate organisational information which contributes to the attainment of organisational goals, objectives and success. An empirical study was conducted to determine employees’ acceptance of elec-tronic newsletters by means of an adapted technology acceptance model, self-administered, e-mail survey disseminated to employees of a higher education institution. The study followed a quantitative research approach, utilising re-gression in the analysis of the data. Based on the research results, employees do accept the electronic newsletter for the dissemination of organisational information, albeit with suggestions on how it can be better utilised in future. / Business Management / M.

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.

In an era of digital convergence, people in related fields are devoted to activities of digitalization, especially in digital TV. This research is based on the Information System Success Model from Technology Acceptance Model (TAM) and aimed to understand the factors that affect user satisfaction and acceptance behavior. The researcher adopts the methodology of questionnaire survey. After statistical data analyses, the results show the main factor that influences MOD users¡¦ intention to use is perceived usefulness. Furthermore, perceived usefulness is influenced by perceived ease of use and user satisfaction. Three factors related to perceived ease of use and user satisfaction are program content quality, system quality and service quality of MOD. However, the influence of information quality is not significant. This research successfully constructs a technology acceptance model for MOD development and contributes for reference not only to future researches on users concerning innovative technologies but also to specific guidance for MOD operators to improve their services, expediting the development of digital TV in Taiwan.

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.
