    The critical determinants for e-commerce, e-business, and other enterprise information systems adoption in SMEs have been well-documented. The critical determinants for m-commerce adoption in SMEs, however, are still limited, especially in SMEs in developing countries. This paper develops a measurement instrument for investigating the critical determinants of m-commerce adoption in Vietnamese SMEs. A preliminary study is conducted for confirming the reliability and validity of the instrument based on the data collected from 172 managers of Vietnamese SMEs using an online survey. The Cronbach’s alpha and the composite reliability values of the proposed variables strongly support their reliability. The results of the exploratory factor analysis confirm constructs’ discriminant validity. The average variance extracted values confirm constructs’ convergent validity. This study contributes to the identification of the critical determinants for m-commerce adoption in SMEs. It provides a comprehensive framework for assessing the critical determinants for m-commerce adoption in SMEs in developing countries

    Extent of Adoption as Opposed to Adoption: Case of E-Procurement

    Get PDF
    Existing literature has given much attention to e-procurement adoption, rather than to the extent of e- procurement adoption. In most countries, e-procurement is being adopted at a slow pace by the corporate world, especially by small and medium enterprises (SMEs) that have traditionally been late adopters of any advanced technologies, due in large part to their resource constraints. This paper describes a project which aims to develop a measure of the extent of e-procurement adoption and to examine the key factors that influence the extent of e-procurement adoption in New Zealand SMEs. An integrated model of the Technology-Organization- Environment (TOE) framework and Diffusion of Innovations (DOI) theory is described and a cross-sectional survey is discussed. The model will be tested using data from the Chief Executive Officers (CEOs) of the SMEs

    Regression analysis has become more popular among researchers as a standard tool in analyzing data. This paper used fuzzy linear regression model (FLRM) to predict tumour size of colorectal cancer (CRC) data in Malaysia. 180 patients with colorectal cancer received treatment in hospital were recorded by nurses and doctors. Based on the patient records, a triangular fuzzy data will be built toward the size of the tumour. Mean square error (MSE) and root mean square error (RMSE) will be measured as a part of the process for predicting the size of the tumour. The degree of fitting adjusted is set between 0 and 1 in order to find the least error. It was found that the combination of FLRM model with fuzzy data provided a better prediction compared to the FLRM model alone. Hence, this study concluded that the tumour size is directly proportional to several factors such as gender, ethnic, icd 10, TNM staging, diabetes mellitus, Crohn’s disease

    The use of pozzolanic materials in concrete provides several advantages, such as improved strength and durability. This study investigated the strength properties of rice husk ash (RHA) concrete under severe durability (sodium sulphate attack). Four RHA replacement levels were considered in the study: 10%, 20%, 30%, and 40% by weight of cement. The durability performance of the RHA blended cement exposed to sodium sulphate solution was evaluated through compressive strength, reduction in strength, and weight loss. Test results showed that RHA can be satisfactorily used as a cement replacement material in order to increase the durability of concrete. Concrete containing 10% and 20% of RHA replacements showed excellent durability to sulphate attack. The results also indicate that the amount of Ca(OH)2 in the RHA blended cement concrete was lower than that of Portland cement due to the pozzolanic reaction of RH

    Internet marketing benefits for South African SME owner-managers

    Published ArticleWith the recent explosion of global marketing strategies, business enterprises have to contend with severe and escalating competition. To sustain competitiveness, small and medium enterprises (SMEs) in South Africa should produce high-quality, customised goods and services efficiently. Adoption of Internet marketing technologies is fundamental towards meeting this challenge. However, the adoption and diffusion of technologies in marketing practices is the outcome of purposeful processes emanating from the realisation by SMEs that adoption of these technologies yields significant paybacks. The purpose of this study was to establish the managers' perceptions of the benefits of Internet marketing adoption in small and medium enterprises. Using a quantitative approach, a questionnaire was administered to owner-managers of small and medium enterprises in the Vaal Triangle in South Africa. A total of 269 questionnaires were completed, returned and considered useful for the survey. Data were analysed using descriptive statistics and factor analysis in order to establish the factors considered to be the salient Internet marketing benefits. Four underlying factors were extracted namely: customer relationship building, information gathering, promotion and enhanced productivity. The mean scores indicated that information gathering was perceived as most important, but after sturdier tests for association were applied to the data set, customer relationship management demonstrated the most significant and positive correlation with SME productivity. As such, there is need for the small and medium enterprises to develop strategies to expand and sustain the identified benefits of Internet marketing

    Predicting intention to adopt B2B electronic commerce in Jordan: The moderating role of trust and dependency

    Get PDF
    Business to Business Electronic Commerce (B2B EC) has great potentials to extend firms’ competency and efficiency. As such, Jordan has an objective to increase the diffusion of this technology. Despite extensive government efforts, the adoption of B2B EC is still limited. Consequently, there have been extensive efforts to better understand the phenomena. Yet, documented findings regarding the determinants of the adoption are not altogether consistent. To provide more insight, this study developed a research model utilizing the Technological, Organizational, and Environmental (TOE) framework to identify the determinants of the firms’ propensity to adopt B2B EC. Since B2B EC is an inter-organizational phenomenon supporting transactions of partnerships, this study emphasizes the context of partnership characteristics. Grounded on inter-organizational theories, this study hypothesized that partnership characteristics, namely trust and dependency, moderate the role of TOE motivating factors. Moreover, given that B2B EC is used on both sides of the buyer/seller relationship, this study examined the differences and similarities in the perception of the marketing and purchasing departments regarding the determinants of the B2B EC adoption. A total of 798 questionnaires were self administrated to marketing and purchasing managers in 462 firms that have large registered capital in Jordan. In total, 114 marketing and 125 purchasing managers participated in this study. Marketing and purchasing responses were analyzed separately using the Partial Least Squares approach. The result revealed that the marketing and purchasing departments do have different views regarding the determinants of the adoption, specifically in terms of the role of Relative Advantage and Competition Pressure. Moreover, the results showed that the moderating role of trust was less pronounced. Meanwhile, the moderating role of dependency was partially supported particularly in the purchasing perspective. These findings have demonstrated how dependence asymmetries between trading partners may change the adoption motivations. They further explain the importance of considering the views of the business partner for the adoption to be done successfully

    This paper is to shed light on the use of electronic business and mobile applications in Saudi organizations to perform their various activities. The paper examined the validity of a previous model that was found from the literature, to identify the most significant factors that affect the intention to adopt mobile electronic business within Saudi organizations. The research suggests and tests seven hypotheses on a population consists of employees in public and private sectors. Therefore, a regular random sampling procedure was used in which 256 respondents were identified.Structural equation modeling had been performed to analyze the collected data, giving more superior empirical results that led to reject five of the seven hypotheses. Results indicate that mobile electronic business features and opportunities as well as social influence both positively affect the intention to adopt mobile electronic business in Saudi organizations.
