The purpose of this paper is to investigate the relationships between self-esteem (SE), university commitment and organizational citizenship behaviors (OCBs) within a higher education setup.

A convenience sample of 354 students in a three-year higher national diploma awarding technical university in Ghana participated in the study via the completion of self-administered questionnaires. Descriptive statistics and partial least square-based structural equation modeling (PLS-SEM) were used to analyze data.

Path results using a PLS-SEM analysis showed a positive and significant association between SE and OCBs and university commitment among the students. Furthermore, OCBs were found to partially mediate the relationship between SE and university commitment.

The findings of the study provide important implication for management of higher education institutions. Management of higher education institutions must orient academic and non-academic staff to adopt communication strategies that help to improve students’ self-worth and assertiveness. All students should be encouraged to participate in extra-curricular activities in order to build students’ beliefs about themselves and self-confidence.

This paper is one of the first to have tested a model including SE, university commitment and OCBs in a technical university setup from a developing country perspective.

This study aims to investigate the relationship between brand positioning and business performance, as well as the mediation effect of brand equity between them within the context of Ghana’s alcoholic beverages industry.

A sample of 196 staff across four alcoholic beverage firms in Accra, Ghana was selected using a judgemental sampling technique. A structural equation modelling approach using partial least squares was used to conduct the analyses to answer the research hypotheses.

All the hypotheses were confirmed in line with extant literature. Specifically, the study found a positive relationship between brand positioning and business performance. The study also found that brand equity partially mediates the relationship between brand positioning and business performance.

The study serves as a useful guide to strategy and policy formulation in branding in general and specifically on how brand positioning can be effectively deployed as a key strategy to enhance business performance.

The study has practical implications not only for the marketing and sale of alcoholic beverages in Ghana to achieve financial performance but also for lasting competitive advantage.

Ghana has recently reviewed its renewable energy Act 835 with an objective of providing 10% of its energy from renewables by 2020 (Ackah and Asomani, 2015). Meanwhile, solar Photovoltaic (PV) accounts for less than 2% of the energy mix (Energy Commission, 2018). In combating environmental issues such as climate change and meeting these policy targets, there is the urgent need to increase investment into the renewable sector. Therefore, the purpose of this paper is to critically examine the impeding constraints to photovoltaic investment in Ghana.

The Literature evaluation was carried out of critical constraints surrounding PV investments. Questionnaire was developed and administered online using Google form. Descriptive statistics was used to describe the features of each constraint. In addition, inferential analysis using relative importance index was used to rank these indicators. Again, one sample t-test was used to test the significance of the indicator. Multiple indicators were used to measure the latent constructs. Finally, independent test of mean equity was used to test relationship between the working experiences of despondence who have worked with solar PV below five years and those who worked from five years to ten years.

The research has highlights high installation and maintenance costs, lack of access to long-term capital finance, access to affordable consumer finance and lack of support to research and development as the major investment obstacles to solar PV investment in Ghana.

It is recommended that the Government of Ghana should provide incentives such as tax waivers, which will encourage entrepreneurs, invest into PV. In addition, it is recommended that solar PV companies must collaborate with financial institutions to provide low interest and flexible consumer financing schemed that can enable home users to purchase the technology. Future research should complement this work by focusing on the impact of domestic currency volatility on PV investment. The scope of this study is constrained to the PV industry in Ghana.

This study will serve as a guide to the private sector business owners to help make critical PV investment decisions. It has also brought to the forefront the reason why solar PV account for a small fraction of Ghana’s energy mix.

This paper seeks to espouse the prevailing constraints to PV investment in Ghana and seeks to contribute to already existing literature that will make profound changes in state policy around PV investment. By understanding these difficulties, driving pointers can be recognized to encourage effective future venture inside the sustainable power source area. In this way, the research leads to a better understanding of the impeding factors that hinders PV investment in Ghana. Again, the paper has achieved new discovery with regards to variations between years of experience with PV use. The variation being less than five years with over five years of PV use. By understanding these difficulties, driving pointers can be recognized to invigorate effective future ventures.

The study examines employee perceptions of CSR relating to stakeholders in the telecommunication industry of Ghana. It also analyses the variations in CSR practices among the sampled telecommunication firms.

By means of a survey, the study explored from the perspective of employees the CSR practices of their firms highlighting the stakeholder group they perceive their firms to be focussing on. A self-administered questionnaire was used to gather data from employees working with leading telecommunication firms in Ghana. A total of 177 valid responses were used for the study analysis. Data was analysed by means of descriptive statistics, and differences in respondent views across the different firms were ascertained using analysis of variance test (ANOVA).

The study results demonstrate that although telecommunication firms engage in CSR activities in some respect, generally these activities are directed more at the stakeholder group “society” distantly followed by shareholder group. The authors also find from their target respondents that not so much attention is given to issues relating to the stakeholder group “the environment”. The results also suggest variations exist in the direction of CSR practices by these firms.

Managers of telecommunication firms in Ghana seem to balance the interest of stakeholders by focussing on society rather than prioritizing these stakeholders.

This study contributes to CSR studies highlighting the perception of employees on their companies' CSR practices while comparing practices amongst telecommunications firms. This would help management of these firms to map out strategies to direct their CSR activities based on stakeholder prioritization.

The study examines a mediated, moderated process of students' intellectual engagement from optimism, academic self-efficacy and academic burnout.

Five hundred and twenty-seven participants who completed a self-reported questionnaire were selected using a convenient sampling technique. PLSc was used to test the proposed hypotheses.

Results showed that optimism positively affects students' intellectual engagement and academic self-efficacy. Additionally, academic self-efficacy correlates positively with students' intellectual engagement and further mediates the relationship between optimism and intellectual engagement. Finally, the moderation effect of academic burnout was positive and non-significant.

This paper is among the first to have tested a model including optimism, academic self-efficacy, intellectual engagement and academic burnout in a university setup from a developing country perspective.

The purpose of this paper is to investigate the effect of flood occurrence on mortality rate and life expectancy amongst 53 African countries.

The study utilizes panel data from the period 2000–2018 on 53 African countries and system generalized method of moments (system GMM) for the analysis.

The result indicates that flood occurrence causes the destruction of health facilities and the spread of diseases which reduces life expectancy. In addition, flood occurrence increases mortality rate amongst 53 African countries.

The study recommends that governments amongst African countries should implement strategies being enshrined in Conference of Parties (COP, 2021) on climate change. This will help to reduce the level of climate change and flood occurrence.

Previous studies focussed on the adverse effect of flood occurrence without considering the issue of life expectancy amongst African countries. This study contributes to existing empirical studies by examining the effect of flood occurrence on mortality rate and life expectancy amongst African countries.

African yam bean (Sphenotylis stenocarpa), bambara groundnut (Vigna subterranean), pigeon pea (Cajanus cajan) and lima bean (Phaseolus luunatus) are some of the minor grain legumes found in Nigeria. Their utilization has been very limiting because little is known about their nutritive value. The proximate, minerals and antinutritional factors of two collections of African yam bean, lima beans and pigeon pea, and one collection of bambara groundnut seeds grown in south‐western Nigeria were studied.

Dry seeds of two collections of African yam bean, pigeon pea and lima beans, and a collection of bambara groundnut were collected from Oyo and Ondo States in south‐western Nigeria. The legumes were sorted, milled and stored in polythene bags at 4°C.

The crude protein in the legumes was in the range of 22–37 per cent, crude fat 1.47–4.96 per cent, crude fibre 1.92–7.21 per cent and ash 3.33–5.61 per cent. K, Ca and P were in the range of 0.15–0.52 per cent. Iron content of the seeds was very low. The antinutrients, tannin, phytic acid and trypsin inhibitor were very high when compared to those of cowpea, groundnut and soybean.

It therefore implies that consumption of these legumes will require processes that will reduce their antinutritional factors.

The purpose of this paper is to evaluate the physico‐chemical properties of African star apple (Chrysophylum albidum) components. African star apples are among the under‐utilized fruits in Nigeria therefore, the four succulent components (peel, pulp, juice and pericarp) of the fruit were analyzed and compared with other known fruits.

African star apples were purchased and divided into two portions. The first portion was washed and the juice was expressed manually into a bottle and covered, while in the second portion, the peel, pulp and the pericarp (mucilage on the seeds) were separated. The physico‐chemical analyses (moisture, total solid, pH, titratable acidity, total sugar, carotenoids, ascorbic acid and total soluble solids) were carried out on the four components.

Moisture content ranged from 53.5 per cent in peel to 86.3 per cent in juice, while the peel had higher total solid and the least was in the juice. The pH of peel was lower than that of other components. The peel had lower titratable acidity (1.2 per cent) and sugar (0.9 Brix) while the juice had higher value (5.4 Brix) in sugar and 15.0 mg/100 g carotenoid. The juice was rich in ascorbic acid (28.5 mg/100 g) followed by the pulp (25.0 mg/100 g). The pulp had higher total soluble solids (24.8 per cent) and the least was in the pericarp (9.8 per cent).

The physico‐chemical properties of the African star apple fruit gave an indication of the usefulness of this fruit in brewing industry especially for wine making and jelly or jam manufacture. Processing of this fruit will curb wastage during its season and make it available in different form.

To set out internationally accepted definitions of information literacy and examine them in the Nigerian context.

The paper takes an initially theoretical and expository approach by setting out definitions of information literacy (IL) and contrasting other different but related concepts, such as ICT literacy, before going on to cite documented theory and practice in a variety of countries. After this, comparisons are drawn between such external standards of IL practice and prevalent approaches to information literacy acquisition in Nigeria as documented by authors and as experienced in practice.

There are important parallels in IL theory and practice between Nigeria and other countries with well‐established IL traditions, but factors such as economic instability, under‐resourcing and computer (ICT) illiteracy inhibit the full development of IL programmes.

The paper outlines clear steps that need to be taken to advance IL standards in Nigeria.

The paper offers insight into the national IL situation in Nigeria, formulates a relevant set of IL statements, and puts Nigerian practice into an international context.

Clinical governance (CG) is crucial for healthcare quality of care improvement and safeguarding high standards of care. Little is known about CG in sub-Saharan Africa. The authors assessed health workers' perceptions of CG and hospital performance in Ghana's psychiatric hospitals.

A cross-sectional survey was conducted among 230 health workers across two psychiatric hospitals in Ghana. Data were collected with a structured questionnaire and analyzed with Statistical Package for Social Sciences (SPSS), version 23.0.

The majority (59.5%) of the respondents were females. The authors found that less than five in ten respondents felt that the hospitals have adopted measures to promote quality assurance (43.2%) and research and development (43.7%). However, a little above half of the respondents felt that the hospitals have adopted measures to promote education and training (57.7%); clinical audit (52.7%); risk management (50.7%) and clinical effectiveness (68.6%). The authors also found a statistically significant association between CG and hospital performance (p < 0.05).

There was a positive relationship between CG and hospital performance. Therefore, investing in CG may help to increase hospital performance.

This is the maiden study to investigate CG and hospital performance in Ghana's psychiatric hospitals and one of the few studies in Africa. This study makes a modest contribution to the global discourse on the subject matter.
