Antecedents and Effects of Computer Self-Efficacy on Social Networking Adoption among Asian Online Users

The main objective of this study is to identify the antecedents as well as the effects of computer self efficacy on information systems acceptance and use. The study conducted in the context of social networking sites adoption. 255 respondents from Bangkok, Thailand were participated in this research. Structural equation modeling techniques has been employed to analyze the data collected. Results reveal that basic computer knowledge and previous computer experience positively influence an individual’s computer self efficacy as well as their intention to use social networking programs. Results also show that Social factors doesn’t play a major role in improving an individual’s computer self efficacy. Computer self efficacy is found to be directly influencing perceived usefulness and indirectly influencing intention to use an information system

Quantification of SSVEP responses using multi-chromatic LED stimuli: Analysis on colour, orientation and frequency

Most LED visual stimulators used in steady state visual evoked potential (SSVEP) brain-computer interface (BCI) use single LED sources to elicit SSVEP responses. In this study, we tested the hypothesis that different orientations would have different responses in different participants and aimed to develop a portable LED based stimulus design which consists of a small number of RGB LEDs arranged in a line which can be oriented horizontally or vertically. The colour and frequency of the flicker were controlled by a portable microcontroller platform. The study investigated the performance of the SSVEP from five participants when the LED stimulus was displayed vertically and horizontally for a period of 30 seconds. The frequency range used was from 7 Hz to 11 Hz with three primary colours: red, green and blue in both orientations. Furthermore, we also compared the effect of vertical and horizontal orientations using four different frequencies and three colours to test visual fatigue reduction. The results of the analysis using band-pass filtering and Fast Fourier Transform showed that the green horizontal LED stimulus orientation gave the highest response and viewing comfort in all the participants rather than the vertical orientation

An Analysis of Personality Traits and Learning Styles as Predictors of Academic Performance

The present study examined the influence of Big Five personality traits and learning styles on cognitive and affective academic performance, and gender differences in learning styles. A survey research was employed to collect the data from the target population of students. Participants (N = 1,529) were students who enrolled in Business Administration and Communication Arts at Assumption University of Thailand.Overall, the results indicated that personality traits found to be better predictors of cognitive and affective academic performance than did learning styles. Conscientiousness was a significant contributor of academic performance. Among five personality traits, Conscientiousness, Openness, Agreeableness significantly predicted cognitive academic performance, whereas Conscientiousness, Openness, Agreeableness, and Emotional Stability significantly predicted affective academic performance. Learning styles were also related to cognitive academic performance. Moreover, students in Business Administration reported higher scores in Conscientiousness, Agreeableness, and Emotional Stability than those in Communication Arts. The results showed no significant differences in learning styles between genders

The integration of information technology in higher education: a study of faculty’s attitude towards IT adoption in the teaching process

Es una realidad que el avance de la Tecnología de la Información revolucionó las prác - ticas y estrategias de negocios de industrias enteras. El campo de la educación superior no es una excepción a este fenómeno. Los colegios de estudios superiores y las universidades de todo el mundo están invirtiendo una considerable cantidad de dinero para crear recur - sos de Tecnología de la Información que cumplan con las necesidades educativas de sus alumnos y profesorado. Si bien las universidades estimulan a sus cuerpos de profesores a adoptar las nuevas tecnologías para su preparación e impartición de clases, diversos otros factores influyen en la integración o resistencia a la aceptación de estas tecnologías. Son ejemplos de estos factores la edad, el grado más alto de educación obtenido, la experien - cia en la enseñanza, competencia en computación, experiencia previa en computación, disponibilidad de tecnología, apoyo institucional, etcétera. Con base en el soporte teórico de la Teoría de Difusión de Roger, se desarrolla un modelo conceptual para identificar los factores críticos de éxito que influyen en la adopción de la Tecnología de la Información entre los profesorados de instituciones educativas terciarias. El modelo se somete a pruebas empíricas entre los miembros del profesorado de universidades líderes en la región de Asia. Participaron en este estudio 261 docentes de tiempo completo y los resultados muestran que factores tales como autoeficacia en computación, ventaja relativa, compatibilidad y experiencia previa en computación influyen de manera importante en la facilidad percibida de uso y actitud hacia el empleo de tecnologías educativas.

Measurement of B2C E-Commerce Success: Test and Validation of a conceptual model of IS success among Asian consumers

From time to time, large numbers of researchers investigate the success factors of B2C e-commerce systems. However majority of those were conceptual studies. Though some empirically validated studies were published on B2C e-commerce systems, very few focused on Asian consumers. The study aims to fill this gap by studying ecommerce success factors among Asian online consumers. Another important objective of this study is to include factors such as perceived security, privacy, trust and perceived cost of transactions into the existing ecommerce success models. Based on the IS success model proposed by DeLone and McLean and its further respecification and validation attempts made by other researchers later, a revised conceptual model is formulated. The model is tested and validated using the data collected from 240 Asian online consumers living in Thailand. The research generated 8 inter related dimensions of e-commerce system success which are information quality, system quality, service quality, trust, perceived sacrifice, perceived value, online customer satisfaction and repurchase intention. Results show that the user satisfaction and perceived value are the two important factors influencing the individuals to repurchase products and services from online portals. Online customer satisfaction is influenced by trust, perceived value, service quality, information quality and system quality. On the other hand, three quality dimensions as well as the perceived sacrifice construct influence perceived value. This study also proved that user‟s trust in the system is influenced by system quality and service quality of the e-commerce system

Integración de la tecnología de la información en la educación superior: un estudio de la actitud del profesorado hacia la adopción de TI en el proceso de enseñanza

It is a reality that advancement of Information Technology revolutionized the busi-ness practices and strategies of entire industries. The field of higher education is not an exception to this phenomenon. Colleges and universities around the world are investing considerable amount of money to create Information Technology resources that meet their student’s and faculty’s instructional needs. While universities encourage their faculties to adopt the new technologies for their preparation and delivery of classes, various other fac-tors influence the integration or resistance of acceptance of these technologies. Age, highest education earned, teaching experience, computer competency, prior computer experience, availability of technology, Institutional support etc. are examples of these factors. Based on the theoretical support of Roger’s Diffusion Theory, a conceptual model is developed to identify the critical success factors that influence the adoption of Information Technology among faculties of tertiary educational institutions. The model is empirically tested among the faculty members of leading universities in Asian region. 261 full time lecturers partici-pated in this study and the results show that factors such as computer self-efficacy, relative advantage, compatibility and prior computer experience are significantly influencing their perceived ease of use and attitude towards using educational technologies.Es una realidad que el avance de la Tecnología de la Información revolucionó las prác-ticas y estrategias de negocios de industrias enteras.

Extensive gingival myiasis - Diagnosis, treatment, and prevention

Myiasis is a rare disease primarily caused by infestation of tissue by larvae of houseflies. Oral myiasis is still more “rare” and “unique” owing to the fact that oral cavity rarely provides the necessary habitat conducive for a larval lifecycle. Here we report a case of extensive gingival myiasis, in an 81-year-old female patient, diagnosed and treated successfully in our department. The case is discussed in relation to its clinical presentation, etiopathogenesis, management, and prognosis
