This study aimed to determine the prevalence and risk factors of hepatitis B virus (HBV) infection among medical laboratory science students (MLSSs) in the University of Health and Allied Sciences (UHAS), Ghana.

A cross-sectional study design was employed to recruit a total of 178 students into the study. A self-administered questionnaire was used to gather relevant information on risk factors, and a hepatitis B diagnostic test kit was used to test for HBV infection. Descriptive, chi-square test, bivariate and multiple logistic regression statistical analysis were computed. Significance was observed at p < 0.05.

The prevalence of HBV infection among MLSSs was 6.7%. Torn gloves and splash of blood and body fluids contributed to 43.0% and 28.0% of all the risk factors of HBV infection, respectively. Also, 43.3% of students had received at least one dose of the hepatitis B vaccination. Sharp object-related injury and torn gloves increased the odds of HBV infection, while vaccination decreased the odds of HBV infection.

This study reveals the prevalence of HBV among MLSSs, who are recognized as being among the high-risk student populations aside from student nurses.

This study aims to focus on the nexus between off-grid systems and impacts on islands and remote villages in Ghana by investigating the sources and cost of energy, willingness to pay for electricity and impacts of off-grid energy on the local economy, education, health, social activities, the environment and migration.

Data were obtained from 110 households; heterogeneous impact analysis of off-grid technologies, average treatment effect by inverse probability weights (IPW) and inverse probability weighted regression adjustment (IPWRA) models were used to analyse the data.

The sources of energy are gas, kerosene, wood fuel and dry-cell battery. All households in communities with neither electricity nor off-grid system were willing to pay for electricity. Households without off-grid systems (US$8.1) were willing to pay higher amounts per month for electricity. The off-grid technologies improve the local economy, social activities, security, the environment, education and health as well as reduce out-migration.

Most of the literature on mini-grid/off-grid systems have been from the engineering and the technical perspective, with a few on the socioeconomic impacts of the systems and consumer engagements. Besides, methods including descriptive statistics, energy technology sustainability framework and qualitative analysis were used in these studies. Nevertheless, the authors used a more rigorous method of the doubly robust inverse probability weighted regression adjustment model and a heterogeneous method to model the impact analysis of off-grid systems.

This paper aims to assess the choice of supermarkets for purchasing fresh agricultural products among urban consumers in Ghana.

Likert scale was used to investigate reasons for purchasing agricultural products from supermarkets, while heteroskedastic probit was used to estimate the determinants. Beta regression was used to examine the determinants of the proportion of food expenditure on raw/unprocessed agricultural products.

The principal reasons for purchasing agricultural products from supermarkets are convenience, a guarantee of assorted products, high-quality products and food safety, constant supply of products, conducive shopping environment, excellent customer service and social influence. The probability of purchasing agricultural products from supermarkets is high for consumers who are either males, young, educated, high-income earners or salaried workers. Consumers residing closer to supermarkets have a greater probability of shopping for agricultural products from same. The proportion of food expenditure on unprocessed agricultural products increases with age but decreases with education and distance to local markets.

Few prior studies have investigated supermarket’s surge in developing countries and its connection with consumer food-outlet choice. Unfortunately, little is evident in the extant literature on consumers' choice of supermarkets as purchasing outlets for fresh agricultural products. Hence, this study closes the gap on consumers and fresh agricultural product purchases from supermarkets in Ghana. Results from the study will provide grounding evidence to supermarket owners to adjust their services to meet consumers’ needs and provide relevant information to evolving supermarkets or investors who may venture into the supermarket business on the attributes that influence consumers to use supermarkets as a purchasing outlet.

Credit is essential in the farm business because it facilitates the adoption of productive technologies such as irrigation. However, access to credit remains a significant hurdle for sub-Saharan Africa, including Ghanaian farmers. Therefore, the authors assessed credit utilization and the intensity of borrowing by irrigated rice farmers in the Upper East region. In addition, how extension moderates the amount borrowed was analysed.

The multistage sampling approach was used in the study. The Tono and Vea irrigation schemes were purposively selected. Proportionally, 318 rice farmers were sampled from the Tono irrigation scheme and 159 from the Vea irrigation scheme. Cragg's double hurdle and moderation analysis were used.

It was uncovered that gender, age, years of farming, total farm size, rice farm size, contract farming and off-farm employment explain farmers' decision to borrow. On the other hand, the intensity of borrowing was influenced by gender, age, years of farming, rice farm size, contract farming and the number of extension contact. The moderation analysis revealed that extension contact improves the amount borrowed by farmers.

While there are irrigated rice farmers in other regions of Ghana, this study was limited to rice farmers under the Tono and Vea Irrigation schemes in the Upper East region.

This study investigated the moderating role of extension contact on amount borrowed in Ghana. This makes a modest addition to the limited literature on the moderating role of extension and credit access.

The paper aims to examine fall armyworm's (FAW) effect on Ghana's farming households' income and food security status.

A sample of 225 farmers, including FAW-infested households and non-FAW-infested households, were interviewed. Gross margin (GM) analysis was used to estimate farmers' farm revenues, and the Household Food Insecurity Access Scores (HFIAS) was employed to measure the food security status of the households. The seemingly unrelated regression (SUR) was adopted to investigate the effect of FAW infestation on gross income and food security.

From the study, FAW attack is predominant during the vegetative stage of the maize plant. The empirical results revealed that FAW-infested farms incur loss, whereas non-FAW-infested farmers gained profit. Also, FAW-infested households were mildly food insecure, while non-FAW-infested households were food secured. The results of SUR analysis reveal that FAW infestation decreased farmers' income from maize production and rendered them food insecure.

One limitation of this study is that it largely depended on a survey; however, future studies can combine both survey and experimental data from the farmers' fields during minor and major growing seasons of maize.

Given the negative consequences of FAW, studies have been conducted across Africa and globally. However, most of these studies concentrated on using geographic information system (GIS) and descriptive statistics without necessarily quantifying the effect of FAW on food security and the profit margins of farming households. Therefore, this study adds to the little literature on the effect of FAW on food security and GM from maize production, which has received less attention in Ghana to the authors' best knowledge.

The unavailability and inadequate use of cashew seedlings for propagation are part of the challenges facing the cashew sub-sector in Ghana. However, promoting investment into cashew seedling production should be based on the analysis of the profitability and viability of such a venture as well as the respective determinants of farmers' demand for the planting material.

This study used gross margin/contribution, net margin and contribution ratios to analyse the profitability of cashew seedling production under four different business models. Also, the determinants of choice of planting material for cashew plantation among farmers was analysed via a multinomial probit regression.

The study revealed that cashew seedling production is profitable with a gross margin of $8,474, $2,242, $1,616 and $1,797 and contribution to sales of 31–53% for the various business models. The positive determinants of the use of cashew seedlings were off-farm job participation and extension contact, whereas farm size and age of plantation negatively influenced the use of seedlings. Land acquisition method also influenced the use of both seedlings and seeds negatively.

The findings provide empirical evidence of the viability and profitability of cashew seedling production as a viable business venture and off-farm opportunity in rural areas. The information from the study will help major stakeholders in cashew production to understand the type of farmers who use seeds and seedlings as well as the reasons for using or otherwise.

Significant research in the cashew value chain had focussed on the profitability of cashew plantation with little literature on profitability and viability analysis of cashew seedling production. Similarly, this study provides a significant value chain job opportunity as well as literature on the choice of cashew seedlings among current and prospective end-users.

The purpose of this study is to explore the direct and indirect effects of perceived provider professionalism and service recovery in enhancing patient satisfaction in a developing country.

This study used a survey method to investigate satisfaction among health-care consumers. This study used data collected from 210 health-care consumers to empirically test the hypotheses via structural equation modeling

This study found that service recovery has a significant direct effect on patient satisfaction. Though this study did not find perceived provider professionalism to have a direct effect on patient satisfaction, it found an indirect effect in the relationship via service experience. Thus, service experience fully/completely mediates the relationship between perceived provider professionalism and patient satisfaction, while partially mediating the significant relationship between service recovery and patient satisfaction.

The results further underscore the need for health-care organizations in developing countries to focus on mindfully developing operations-oriented strategies that lead to the delivery of memorable service experiences for patients.
