The large-scale environmental influence in attaining sustainability is a serious problem for organisations. Organisations are coping with various negative environmental challenges, and social media is one of the driving forces involved in dealing with this difficulty owing to the enormous number of users of social media. Organisations embrace social media to accomplish various goals, such as information sharing, connection building, brand development, boosting awareness, and gathering customer insights. In addition, social media is a critical factor in influencing organisational sustainability performance on an individual and group level. This paper aimed to examine social media and organisational sustainability performance goals, namely themes, functional areas, and practices in the age of social networking. Identifying the goals and themes provided ...

Following Tinto’s integration theory and Bean’s attrition model, this study proposes a research model to investigate whether students prone to attrition can be pre-emptively identified through self-evaluating academic factors contributing to their learning progress. Theoretically, the learning progress is identified with student success, represented by factors amenable to intervention including the interaction with peers and instructors, teaching effectiveness, exam scores, absenteeism, students’ effort, and academic course-related variables. An exploratory and confirmatory factor analysis of 530 undergraduate students revealed that the indicators of learning progress in such students were channeled into two constructs. The results indicated that the teacher effectiveness and learning materials contributed most to the learning progress. Structural equation modelling revealed tha...

This study reviews various implementation of adaptive feedback, based on the four adaptation characteristics: means, target, goal, and strategy. This review focuses on 20 different implementations of feedback in a computer-based learning environment, ranging from multimedia web-based intelligent tutoring systems, dialog-based intelligent tutoring systems, web-based intelligent e-learning systems, adaptive hypermedia systems, and adaptive learning environment. The main objective of the review is to compare computer-based learning environments according to their implementation of feedback and to identify open research questions in adaptive feedback implementations. The review resulted in categorizing these feedback implementations based on the students’ information used for providing feedback, the a...

However, users of this platform have posed dissatisfaction over the slow response and the preference for user domains due to the overwhelming information in CQA websites. Numerous past studies focusing on expert recommendation are solely based on the information available from websites where they rarely account for the preference of users’ domain knowledge. This condition prompts the need to identify experts for the questions posted on community-based websites. Thus, this study attempts to identify ranking experts’ derived from the tag relationship among users in the CQA websites to construct user profiles where their interests are realized in the form of tags. Experts are considered users who post high-quality answers and are often recommended by the system based on their previous posts and associated tag...

Online reviews became an excellent source for sentiment analysis to determine a customer's sentiment about a business. This insight is valuable asset for businesses, especially for tourism sector, to be harnessed for business intelligence and craft new marketing strategies. However, traditional sentiment analysis with flat classification and manual aspect categorization technique imposes challenges with non-opinionated reviews and outdated pre-defined aspect categories which limits businesses to filter relevant opinionated reviews and learn new aspects from reviews itself for aspect-based sentiment analysis. Therefore, this paper proposes sentiment attribution analysis with hierarchical classification and automatic aspect categorization to improve the social listening for diligent marketing and recommend potential business optimization to revive the business from surviving to thriving after this pa...

With higher level of education and information technology background, postgraduate students of computer science ought to have a different information seeking behavior. Therefore it is interesting to explore their information seeking behaviors and to investigate to what extent they might constitute a unique user group. The objective of this research is to explore and analyze computer science postgraduate student’s information seeking behaviors. A Survey was conducted at Faculty of Science Computer and Information Technology, University of Malaya. The sample consists of 140 postgraduate students. The quantitative data were analyzed using the statistical program SPSS. The results provide an insight into how computer sciences postgraduate stud...

Majority of the studies on Facebook usage are based on individual perspective and some are from organizational perspective. However, not many studies had investigated the actual impact of Facebook usage on organizational performance. This paper investigates the influence of personality traits of SME owners on Facebook usage and its subsequent impact on organizational performance. A total of 259 SMEs responded to the survey and the result of the survey showed that perceived desirability and openness of SME owners positively influences Facebook usage. Facebook usage also has a positive impact on both organizational financial and non-financial performances. This study provided a clearer view on the real importance of Facebook and its benefits. The results would motivate and guide organizations in the adoptio
