Technology Acceptance Model in M-learning context: A systematic review

Abstract Various review studies were conducted to provide valuable insights into the current research trend of the Technology Acceptance Model (TAM). Nevertheless, this issue still needs to be investigated from further directions. It has been noticed that research overlooks the investigation of TAM with regard to Mobile learning (M-learning) studies from the standpoint of different perspectives. The present study systematically reviews and synthesizes the TAM studies related to M-learning aiming to provide a comprehensive analysis of 87 research articles from 2006 to 2018. The main findings include that most of the TAM studies involving M-learning focused on extending the TAM with external variables, followed by the studies that extended the model by factors from other theories/models. In addition, the main research problem that was frequently tackled among all the analyzed studies was to examine the acceptance of M-learning among students. Moreover, questionnaire surveys were the primarily relied research methods for data collection. Additionally, most of the analyzed studies were undertaken in Taiwan, this is followed by Spain, China, and Malaysia, respectively among the other countries. Besides, most of the analyzed studies were frequently conducted in humanities and educational context, followed by IT and computer science context, respectively among the other contexts. Most of the analyzed studies were carried out in the higher educational settings. To that end, the findings of this review study provide an insight into the current trend of TAM research involving M-learning studies and form an essential reference for scholars in the M-learning context.

PLS-SEM in Information Systems Research: A Comprehensive Methodological Reference

The partial least squares-structural equation modelling (PLS-SEM) has become a key approach for validating the conceptual models across many disciplines in general, and the Information Systems (IS) in specific. This is guided through the assessment of the measurement and structural models. Several research articles were carried out to provide an extensive coverage of the usage and application of PLS-SEM. These articles were mainly concentrated on providing guidelines of how to use PLS-SEM in terms of reflective and formative measures, measurement and structural models, and the steps for analysing a particular conceptual model. Nevertheless, there are several steps and procedures that precede the evaluation of the measurement and structural models. The understanding of these steps and procedures is very important for many IS scholars, Ph.D. and Master students who are always struggling to find a comprehensive reference that could guide them through their research journey. Hence, the main contribution of this study is to a build a comprehensive methodological guideline of how the PLS-SEM approach can be employed in the context of IS adoption and acceptance, starting from the research design stage till the assessment of the measurement and structural models. This study may serve as a comprehensive reference for formulating the methodology in the IS adoption and acceptance related studies in the case of PLS-SEM employment.

For a good website, the website must be useful, easy to use, easy to understand and easy to navigate. This paper analyzes the attributes that give some influence to the website usability and the impact of intention to use attributes the website. Usability is attribute that cannot be observed directly. It more on user feel and think about the website in other word it more on user perception to particular web site. 82 respondents are participated in this study. The respondents are given task to explore and find the information in the given website. PLS – SEM is used to analyze the data to see either all attributes are give influence to the website usability.

The impact of knowledge management processes on information systems: A systematic review

Abstract Knowledge Management (KM) processes play a significant role in the implementation of various Information Systems (IS). Several review studies were carried out to afford a better understanding of the current research trend of KM processes. However, this issue still needs to be examined from other perspectives. It is observed that previous research neglects the examination of KM processes studies with regard to ISs. The current study systematically reviews and sheds the light on KM processes studies related to ISs aiming to provide a comprehensive analysis of 41 research articles published in peer-reviewed journals from 2001 to 2018. The main findings of this study indicate that knowledge sharing is the most frequent KM process studied, followed by knowledge acquisition and knowledge application. Besides, questionnaire surveys were found to be the primarily relied research methods for data collection in the context of KM processes. In addition, 78% of the analyzed studies registered positive research outcomes. In terms of IS type, most of the analyzed studies focused on investigating the impact of KM processes on E-business systems, knowledge management systems, and IS outsourcing, respectively. Additionally, in terms of data collection, the majority of the analyzed studies were primarily focused on the participants who are IS executives/managers. Furthermore, most of the analyzed studies that achieved positive outcomes were carried out in China. To that end, this review study attempts to demonstrate and detail the recent increase in the interest and the advancement made in KM processes research considering ISs studies, which form an essential reference for scholars in KM field.

E-learning models: The effectiveness of the cloud-based E-learning model over the traditional E-learning model

This paper sought to understand the effectiveness of the traditional and cloud-based e-learning model. The growth of internet has been a game changer in the education sector. The internet has made it easy to for learners and educators to share information interactively, which is vital in enhancing education. Nonetheless, the storage of the content of learning has led to the adoption of cloud computing in the education sector in general and in higher education in particular. The adoption of cloud computing is in line with the objective of saving resources/saving costs and improving the interaction between students and the educators. Cloud-based learning has been slowly gaining popularity, with researchers arguing that it has the potential of replacing/improving the traditional e-learning model. It is worth noting safety (privacy and security) of information and data remains a huge priority for individuals who want to the e-learning model the best learning model for individuals learning from home and for education providers as well. The study utilizes a quantitative technique, where participants were drawn from two institutions. The respondents answered and presented a questionnaire for evaluation. Based on the results of the study, it was clear that the cloud-based e-learning model could effectively address the problems related to the traditional e-learning model.

After analyzed the result, 7 items need to delete from the instrument. Apart from the more technical and general aspects the feedback from the respondents was useful in identifying problematic questions and it was suggested that some questions need to deleted as they were seen to have same meaning with other questions and too difficult to answer for several reason such as because the sentences of the question is difficult to understand and the level of understanding between the question and respondent.

Going Native: Indexing architecture of eXist-db_ An Open Source native XML database system

XML is a markup language specifically designed for the Internet, and it has become the standard for represent and exchange the data on the Internet. With the development of the Internet and day by day, large amount of XML documents are being added to the network continuously in various application domains. Thus, it is become necessary to work out how to create a way to store and manage XML data efficiently inside the databases. There are two methods to represent XML in the databases: (1) XML-Enabled databases which designed for structured data (XML is semi-structured data). And (2) Native XML databases or which designed specifically to store any XML document (structured and semi-structured data). The difference between the nature of the database structure and XML data structure became an important research topic, and this led to emergence Native XML database. This paper presents the indexing architecture of eXist, an Open Source native XML database system.
