The purpose of this paper is to assess the differences pertaining to the resources presently accessible for problem-based learning (PBL) among six colleges of Kwame Nkrumah University of Science and Technology (KNUST) in Ghana.

Data for the study are the cross-sectional type drawn from 1,020 students. Poisson and zero-inflated Poisson (ZIP) models were implemented on the data to ascertain the variations regarding the extent of resources available for PBL across the colleges of the university.

The study outlines the specific resources accessible for PBL across college levels of KNUST. On aggregate, 25.7 per cent reported that their respective colleges have sufficient resources, while 74.3 per cent indicated otherwise. The ZIP model exhibited superiority over the Poisson model, when compared under a Vuong test. As per the ZIP model, none of the colleges appeared to differ significantly in terms of having sufficient resource for PBL.

Findings are applicable to informed decision-making which targets achieving quality education through the use of PBL. Access to sufficient resources that meet the needs of colleges or departments of a University is emphasized.

The application of Poisson and ZIP models to aggregated count data in a PBL setting is novel.

The purpose of the paper is to investigate the quantitative effect of import liberalization on tariff revenue in Ghana.

In an attempt to achieve the objective of the paper, a robust decomposition analytical approach was used to examine how different components of the sources of change in import tax contribute to changes in import tax revenue in Ghana.

The paper concludes that Ghana suffered some revenue loss from the liberalization by reducing the level of average official duty rates, but gained in revenue as a result of real currency depreciation.

It has been suggested that public policy should aim at determining and targeting the optimum level of the average official import duty rates, focus on the identification of the major sources of duty revenue leakage, and substitute sales taxes for tariffs to improve tax revenue sufficiently.

This paper makes explicit the contribution of alternative import policy features to changes in import tax revenue in Ghana.

The purpose of this study is to identify the various traditional foods available in two towns in Ghana and to assess consumer perception about these traditional foods. Traditional foods provide nutritional and health benefits, but their consumption keeps declining, such that some are becoming extinct.

The level of knowledge of consumers and their attitude toward the consumption of traditional foods were determined. A cross-sectional survey was conducted in Sekondi and four areas in Kumasi, with a sample size of 200 in each of the two towns. The data obtained were analyzed using Pearson correlation and Chi-square test for independence.

While consumers had very good general knowledge of the traditional foods, most of them had little knowledge on nutrient compositions of the foods. About 95.5 per cent of respondents in Sekondi consumed traditional foods relative to those in Kumasi (62.5 per cent). There was no linear relationship existing between respondents’ knowledge, attitude and consumption of traditional foods (r < 0.50). More so, respondents’ attitude, knowledge and consumption of traditional foods, mostly, did not depend on the demographic factors (age and education). Other factors such as convenience, economic status of respondents and safety of traditional foods may be contributory factors to the low patronage and consumption of traditional foods.

Most researches on traditional foods in Ghana have mostly focused on food ingredients; therefore, there is little or no available information on consumer perception of prepared traditional foods. Because consumer opinions change over time, there is a need to consistently gather data to help food industries and food service operators meet consumer needs and expectations.

The demand for energy infrastructure projects has increased steadily over the last few decades and has come at a high cost. Disruptive technologies (DTs) have the inherent capability to affect the performance of energy infrastructure projects. Therefore, this research aims to explore the implications of DTs on the performance of energy infrastructure projects.

This research adopts a positivist philosophical position. A quantitative strategy and deductive approach (based on a survey design) guided this study. Sixty-six respondents participated in the study. The study’s population comprised of experts in energy infrastructure projects who possessed a high level of industrial experience including top- and middle-level management of power generation companies. Cochran’s formula was used to select a sufficient sample for the study. Linear regression, one sample test and Cronbach’s alpha were the analytical tools adopted.

This study established that there is an 18.4% increase in the performance of energy infrastructure projects in Ghana when DTs are applied. In order of importance, DTs improve speed of operations in energy projects; reduce operating cost and enhance efficiency of energy projects; drive sustainable economic development; enhance security in energy projects; and improve environmental sustainability of projects. The study also revealed that e-commerce technologies, renewable energy technologies, three-dimensional printing, bar code technology, photogrammetry, global positioning systems, geographic information systems and nanotechnologies were the topmost ranked DTs with the most impact on the performance of energy infrastructure projects.

This is a novel investigation on the implications of DTs on the performance of Ghanaian energy infrastructure projects. This study’s practical implication is evident in both policy and practice. Energy sector policymakers should endeavour to adopt DTs in their operations to enhance sustainability and performance.

The purpose of this paper is to investigate disaster accountability process, and it seeks to advocate for involvement of victims as salient stakeholders in the accountability process.

The authors adopt a case study of the 3rd June, 2015 flood disaster and fire that occurred in Accra, Ghana and draw mainly on interviews, as well as observations and a review of publicly available documents.

Several actors are involved in disaster management in Ghana. These actors play several roles as part of the disaster management process. Coordination is observed among some governmental actors. However, there is a little collaboration among these actors. There are, therefore, no clear accountability relationships between the actors. Moreover, the forms of accountability process are largely upward and internal. So, although we find the victims as salient stakeholders, their perspectives are not prioritised as part of the accountability process.

As a result of less engagement with victims in the accountability process, a central accountability concern, outcomes, namely, benefits for victims in terms of changes in their knowledge, status, attitudes, values, skills, behaviours or conditions were not promoted. Downward accountability should be encouraged to promote better outcomes.

Although some studies on accounting for disasters have been undertaken, there is none in our local context, and also this study has been able to uncover under-representation of victims in the accountability process using adaptive accountability lens.

Following the recent rise in generative artificial intelligence (GenAI) tools, fundamental questions about their wider impacts have started to reverberate around various disciplines. This study aims to track the unfolding landscape of general issues surrounding GenAI tools and to elucidate the specific opportunities and limitations of these tools as part of the technology-assisted enhancement of mechanical engineering education and professional practices.

As part of the investigation, the authors conduct and present a brief scientometric analysis of recently published studies to unravel the emerging trend on the subject matter. Furthermore, experimentation was done with selected GenAI tools (Bard, ChatGPT, DALL.E and 3DGPT) for mechanical engineering-related tasks.

The study identified several pedagogical and professional opportunities and guidelines for deploying GenAI tools in mechanical engineering. Besides, the study highlights some pitfalls of GenAI tools for analytical reasoning tasks (e.g., subtle errors in computation involving unit conversions) and sketching/image generation tasks (e.g., poor demonstration of symmetry).

To the best of the authors’ knowledge, this study presents the first thorough assessment of the potential of GenAI from the lens of the mechanical engineering field. Combining scientometric analysis, experimentation and pedagogical insights, the study provides a unique focus on the implications of GenAI tools for material selection/discovery in product design, manufacturing troubleshooting, technical documentation and product positioning, among others.

This study examines the effect of foreign direct investment (FDI) on employment and economic growth in Ghana and examines the role of technology in these relationships.

This study applied the autoregressive distributed lag (ARDL) bounds testing approach to cointegration and Granger causality tests to data from 1995 to 2017.

Based on the empirical analysis, the key findings are as follows: FDI does not affect economic growth or employment in Ghana. However, technology moderates the relationship between FDI and economic growth and FDI and employment in the short run. The study also finds that technology exerts a positive effect on economic growth in both short and long run, whereas trade has a significantly negative effect on economic growth in Ghana.

The greatest constraint that faced the authors is the nonavailability of data,.

The transfer of technology agreement enshrined in the GIPC Act should be made more robust and unambiguous, to make it a strict requirement for MNEs to be allowed to operate in Ghana. This increases Ghana's gains from FDI inflow.

The GIPC should tighten its monitoring regime so that MNEs do not exceed their expatriate employment quotas. This will ease the burden of unemployment among the youth in Ghana.

This study adds a new dimension to the literature on the impact of FDI on emerging economies by examining the role of technology in the association between FDI and growth, and FDI and employment.

This paper aims to explore the extent to which global reporting initiative (GRI) standards reflect the material concerns of stakeholders in developing countries, with particular reference to Latin America.

The main dataset was a sample of 120 media articles that discussed corporate conduct related to COVID-19 from both developing (Chile, Mexico and Peru) and developed (Australia, UK and the USA) countries. Concerns evident from those articles were compared and then mapped to applicable GRI standards to identify relevant disclosures and gaps. Findings were triangulated by drawing on two additional datasets: Latin American GRI-related academic literature (in Spanish) and submissions to GRI standards.

Media analysis reveals significant differences between developing and developed country concerns, as well as gaps in GRI disclosure requirements in relation to customers, labour standards and corporate interactions with non-government organisations and governments. Analysis of Latin American literature corroborates the concerns raised in media articles regarding employment. Additionally, it points out country-specific issues and calls for increased reporting of corruption. Analysis of the GRI standards development process reveals marked underrepresentation of developing countries, which may contribute to the observed deficiencies in the GRI standards.

This paper contributes to the (surprisingly rare) research concerning the quality of GRI standards and responds to calls for greater attention to developing countries in the SEA literature by showing that GRI standards may not fully meet the needs of users in the developing country context of Latin America. The paper also contributes to practice via specific recommendations for improvement to GRI standards and the standard-setting process and provides a summary of the key findings from Spanish-language Latin American literature.
