This study sought to examine the differential effect of brand quality and brand prestige on brand purchase intentions of mobile phones by students in Ghana. The study also examined the moderating role of network effect, system quality and self-efficacy on the relationship between brand quality and prestige on purchase intentions.

A quantitative research approach was adopted with data collection executed through the application of a questionnaire that was self-administered. A total of 518 completed questionnaires received from the respondents were used for the analysis. Statistical analysis was pursued using a sequential analytical procedure concentrating on purchasing intentions or actual purchases with respect to the choice of mobile phone brands.

The findings indicate that the network externality, system quality and self-efficacy can stimulate the choice of mobile phone brands. The moderating effect of network externality, self-efficacy and system quality were found to be mixed.

Mobile phone companies should skew their investments toward improving the quality of the brand whiles developing effective marketing and differentiation strategies to enhance the brand image and create prestigious brands.

This paper provides researchers with a contemporary perspective toward understanding the key factors that guide students to have informed purchase intentions and enable mobile phone companies to evaluate their strategies

Banking institutions have vigorously pursued the integration of information and communication technology in modern banking services. Unfortunately, empirical support demonstrating the usefulness of this undertaking has largely been scanty. The purpose of this paper is to investigate causal links between the efficiency of information technology (IT) applications and bank performance using data envelopment analysis.

The study adopts the DEA approach to evaluate the bank level cost and IT efficiency. The Vector Error Correction Model Granger causality tests with the forecast error variance decomposition and impulse response functions were subsequently used to examine the causal relationship between the variables.

From the findings, the bank achieved an average level of 99.1 per cent cost efficiency for the sampled period. Also the periods where the bank obtained optimal cost efficiency were in 2005, 2006 and 2014. This culminated into inefficiency scores ranging from 0 to 2.9 per cent, with 2016 financial year as the period of worst cost performance. In addition, the study found that there are both short-run and long-run relationships between IT efficiency and cost performance.

Management should note that any improvement to IT applications may contribute significantly to overall IT performance but for the short period, specifically the first period, by the medium to long-run period, most improvement to overall IT performance emanates from cost performance of the bank.

Some studies have examined the effect of IT on banks in USA and Europe. However, such studies are rare in the African context. This study will contribute to extant literature by add a new dimension of IT and bank efficiency.

Increased competition in the banking sector coupled with long queues in the banking hall has necessitated the introduction of internet banking among banks in Ghana. As a result, internet banking has attracted a great deal of attention from both academicians and practitioners. The purpose of this paper is to examine the effect of internet banking on the performance of banking institutions in Ghana.

In total, 20 banks in Ghana were selected from the Bank of Ghana website for the study. The financial information about the banks’ operations was retrieved from the financial statements of the respective banks for the end of the year 2016. The data envelopment analysis-bootstrap approach with principal component analysis and cluster analysis was used to estimate 49 models.

The findings of the study indicated that the integration of internet banking into traditional banking methods has led to superior bank performance in Ghana. It was observed that while the independent application of internet banking as a strategy to raise performance was not yielding higher returns due to the low patronage of internet services among banking consumers, its integration with possible traditional methods is widely observed among the top performers in the banking industry.

Traditional banking methods, integrated banking service strategies and the internet banking service-oriented strategy emerged as the main banking strategies among the banks.

Extant literature is quite silent on the effect of internet banking on bank performance in Africa. However, this paper is among the first significant attempts to examine the effect of internet banking on bank performance.

The purpose of this study is to introduce new tools to develop a more precise and focused bibliometric analysis on the field of digitalization in healthcare management. Furthermore, this study aims to provide an overview of the existing resources in healthcare management and education and other developing interdisciplinary fields.

This work uses bibliometric analysis to conduct a comprehensive review to map the use of the unified theory of acceptance and use of technology (UTAUT) and the unified theory of acceptance and use of technology 2 (UTAUT2) research models in healthcare academic studies. Bibliometric studies are considered an important tool to evaluate research studies and to gain a comprehensive view of the state of the art.

Although UTAUT dates to 2003, our bibliometric analysis reveals that only since 2016 has the model, together with UTAUT2 (2012), had relevant application in the literature. Nonetheless, studies have shown that UTAUT and UTAUT2 are particularly suitable for understanding the reasons that underlie the adoption and non-adoption choices of eHealth services. Further, this study highlights the lack of a multidisciplinary approach in the implementation of eHealth services. Equally significant is the fact that many studies have focused on the acceptance and the adoption of eHealth services by end users, whereas very few have focused on the level of acceptance of healthcare professionals.

To the best of the authors’ knowledge, this is the first study to conduct a bibliometric analysis of technology acceptance and adoption by using advanced tools that were conceived specifically for this purpose. In addition, the examination was not limited to a certain era and aimed to give a worldwide overview of eHealth service acceptance and adoption.
