Abstract

Purpose

While many researchers have investigated the adoption and usage of online learning in different settings, one area that has yet to be examined thoroughly, particularly in the context of online learning in Yemen, is the self-efficacy role. The purpose of this paper is to extend the Delone and McLean information system success model by incorporating a self-efficacy construct as an antecedent to user satisfaction and actual usage to predict student performance.

Design/methodology/approach

Questionnaire survey method was used to collect primary data from 448 students in nine public universities in Yemen. The six constructs in the proposed model were measured using existing scales. The data analysed using confirmatory factor analysis and structural equation modelling via AMOS.

Findings

Three main results were revealed, namely that overall quality (system, information and service quality) and self-efficacy have a positive impact on user satisfaction and actual usage; that actual usage significantly predicts user satisfaction; and that both user satisfaction and actual usage have a positive impact on student performance.

Research limitations/implications

First as the study population were students from nine public universities, it excluded academics and administrative staff. Second, the study depends on self-reported measures to test the proposed research model. This is because getting objective data about the performance was not probable due to the issue of privacy.

Practical implications

The findings of this study can be a guideline for Yemeni higher education institutions to develop efficient and effective plans to improve the performance of education institutions, and train and develop student ability to use online learning. Additionally, it highlights the areas that university management needs to concentrate on, namely information systems (IS) tools that will contribute to higher student enrolment, address the lack of infrastructure and improve the quality of education outcomes, things which represent Yemen’s main challenges in the higher education sector.

Originality/value

This paper adds to the existing literature of IS by combining overall quality, self-efficacy, actual usage and user satisfaction to predict performance impact of online learning among students in nine public universities in Yemen. Furthermore, the predictive power of the proposed model has a higher ability to explain and predict performance impact compared to those obtained from some of the previous studies.

Abstract

Purpose

“Corrupt practices” is a recurring feature of media coverage. The paper seeks to encourage debates about the influence of institutional structures on agency to break away from methodological individualism. This paper aims to encourage reflections on the role of both the structures and actors which have shaped the continuous expansion of corrupt practices in Nigeria.

Design/methodology/approach

Whilst recognising that deviant behaviour by some individuals is always possible, this paper has rejected methodological individualism and shows the value of locating anti-social practices within the broader socio-political and historical context. Within a socio-political framework, this study adopts the theories of critical realism, developmental state and globalisation to understand the relationship between social agency and society, focusing upon the institutional structures and the role of social actors.

Findings

The evidence shows that socio-political and economic development, politics, power, history and globalisation have continued to reproduce and transform the institutional structures and actors which have facilitated anti-social practices in Nigeria. The paper concludes that large sums of government revenue have been undermined by the anti-social practices of the Nigerian political and economic elite (both local and international), which have enriched a few, but impoverished most, Nigerians.

Practical implications

As a consequence of recurring corrupt practices in Nigeria, there is a pressing need for reform to curb these practices which have had, and continue to have, a serious effect on Nigeria and its future development.

Originality/value

It provides a framework for understanding and explaining the inter-relations of actors and institutional structures and the linkages and influences that have shaped the practices in Nigeria.

Abstract

Purpose

The human capital of a leader and the human capital of the employees who work for the leader can impact the bonus earned by the leader. Little to no research has examined data that includes the maximum potential bonus that could be earned by a leader and the actual bonus earned. This information provides a closer examination of leader performance and the impacts of leader and employee human capital on the bonus earned by the leader.

Design/methodology/approach

The authors use a sample of NCAA college football teams and head coaches over two years to test their hypotheses. They measure the human capital of the team and the human capital of the head coach. In addition, the authors assess the percentage earned by the head coach of the maximum potential bonus possible.

Findings

The authors find that a coach's human capital and the human capital of their team positively and significantly predict the percentage of the maximum possible bonus earned by the head coach.

Practical implications

The results of this study indicate the importance of leader human capital to a leader's ability to earn more of their maximum potential bonus. Additionally, if a leader is able to surround himself or herself with highly talented employees, it will benefit the leader in terms of the amount of bonus earned.

Originality/value

This study extends previous research to provide a more complete picture of factors that influence a leader's ability to earn more of their maximum possible bonus. The authors’ findings that both the human capital of the leader and the human capital of employees who work for the leader impact the amount of bonus earned by the leader add value to human resource management research. Specifically, when examining factors that impact a leader's bonus earnings, it is important to consider not only characteristics of the leader but also factors apart from the leader, such as the leader's employees.

Abstract

Purpose

This study aims to identify the bioactive compounds in the Onion (Allium burdickii [A.B]) bulb using Raman and Fourier transform infrared spectroscopy (FTIR) spectroscopy. It assessed the extraction conditions of bioactive compounds from A.B. while evaluating the best extraction conditions.

Design/methodology/approach

The research opted for an experimental qualitative approach. It examined the extraction conditions of A.B., namely, temperature (°C), time (min) and mass-to-liquor ratio (M:R) using ultraviolet-visible spectrophotometry. Identification of bioactive compounds present in the dye was performed using Raman spectroscopy and the validation of the results was done by FTIR spectroscopy.

Findings

The study determined the best extraction conditions (time, temperature, M:R) for A.B bulb. The study confirmed the presence of bioactive compounds.

Research limitations/implications

The limitation was quantification of bioactive compounds in A.B bulb.

Practical implications

The findings prove that the A.B. bulb can provide a sustainable source of bioactive compounds (functionalized compounds). The study provides suitable extraction conditions for A.B. and further elaborates on the techniques for identifying bioactive compounds in A.B. bulb extracts.

Social implications

The study provides A.B. as a source of bioactive compounds and a clean dye for textile coloration.

Originality/value

To the best of the authors’ knowledge, there is no documented study on the qualitative analysis of bioactive compounds in A.B using Raman and FTIR. Therefore, the study fulfils the identified need to ascertain alternative procedures for the analysis of bioactive compounds.
