Abstract

Purpose

This study aims to assess the effect of water variation on bioethanol production from cassava peels (CP) using Saccharomyces cerevisiae yeast as the ethanologenic agent.

Design/methodology/approach

The milled CP was divided into three treatment groups in a small-scale flask experiment where each 20 g CP was subjected to two-stage hydrolysis. Different amount of water was added to the fermentation process of CP. The fermented samples were collected every 24 h for various analyses.

Findings

The results of the fermentation revealed that the highest ethanol productivity and fermentation efficiency was obtained at 17.38 ± 0.30% and 0.139 ± 0.003 gL−1 h−1. The study affirmed that ethanol production was increased for the addition of water up to 35% for the CP hydrolysate process.

Practical implications

The finding of this study demonstrates that S. cerevisiae is the key player in industrial ethanol production among a variety of yeasts that produce ethanol through sugar fermentation. In order to design truly sustainable processes, it should be expanded to include a thorough analysis and the gradual scaling-up of this process to an industrial level.

Originality/value

This paper is an original research work dealing with bioethanol production from CP using S. cerevisiae microbe.

Highlights

  1. Hydrolysis of cassava peels using 13.1 M H2SO4 at 100 oC for 110 min gave high Glucose productivity

  2. Highest ethanol production was obtained at 72 h of fermentation using Saccharomyces cerevisiae

  3. Optimal bioethanol concentration and yield were obtained at a hydration level of 35% agitation

  4. Highest ethanol productivity and fermentation efficiency were 17.3%, 0.139 g.L−1.h−1

Abstract

Purpose

Banditry is a major social problem in Nigeria that has over time defied series of intervention measures introduced by the federal and state governments to address it. Therefore, this study aims to investigate the counter-banditry strategies of the affected communities in Oyo State, Nigeria.

Design/methodology/approach

The research was exploratory and cross-sectional in design. Situational criminal prevention theory was used as conceptual guide. Data were elicited from community leaders, community members and local security guards using in-depth interview, key-informant interview and focus group discussion methods.

Findings

The results showed that communities affected by banditry problem were adopting different internal and external interventions to combat the criminal act. Although the counter-banditry strategies of the affected communities have brought about a reduction in the occurrence of the criminal act, the problem is yet to be totally eliminated as people still get victimised.

Originality/value

This research expanded the frontiers of knowledge by focusing on the counter-banditry strategies of the communities affected by the problem of banditry and also suggested relevant practical steps that can be taken to further strengthen the existing security architectures in such locations.

Abstract

Purpose

The purpose of this study is to empirically analyse the fiscal revenue implications for oil-dependent African countries in the face of low-carbon energy transition (LET).

Design/methodology/approach

The study combined the novel fully modified ordinary least squares, dynamic ordinary least squares and canonical cointegrating regressions estimators to analyse secondary data between 1990 and 2020 for the three major oil-dependent African Countries (Algeria, Angola and Nigeria).

Findings

The result shows that LET reduces oil revenue and non-revenue for specific countries (Algeria, Angola and Nigeria) and the panel, suggesting that low-carbon energy transiting is lowering the fiscal revenue of oil-dependent African nations.

Research limitations/implications

The seeming weakness of this study is its inability to broaden the scope to include all oil-producing African economies. However, since the study selected Africa’s top three oil-producing states, the sample can serve as a model for others with lesser crude oil outputs.

Practical implications

Oil-dependent African countries must urgently engage in sincere economic diversification in sectors like industry and manufacturing, the service sector and human capital development to promote economic transformation that will enhance fiscal revenue.

Originality/value

With the pace of energy transition towards low-carbon energy, it is not business as usual for oil-rich African countries (Algeria, Angola and Nigeria) due to fluctuating demand and price. As a result, it becomes worthy to examine how the transition is affecting oil-dependent economies in Africa. Also, this study’s method is unique as it has not been used in a similar study for Africa.

Abstract

This study investigated demographic factors, attitude and knowledge of persons with special needs towards COVID-19 in Nigeria between 12 May and 25 May 2020. This cross-sectional online survey was conducted among 72 persons with special needs purposively selected from the six geo-political zones in Nigeria. A questionnaire comprising questions on demographic information (three), knowledge (24) and attitude (28) towards COVID-19 was completed via Google forms by the participants (r=0.78). There were more males (51, 70.8%) than females (21, 29.2%) and the most common age group was 34-44 years (37.5%). The number of participants with a hearing impairment was 34 (47.2%) and the number with a visual impairment was 26 (36.1%). The results indicate adequate knowledge about the characteristics of COVID-19. It was found that 98.6% of the participants had heard about COVID-19; 94.4% were aware that COVID-19 is a contagious disease, 91.7% stated that COVID-19 is a virus and 88.9% reported correctly that the incubation period is 3-14 days. The knowledge about symptoms of COVID-19 among participants was high (x=2.63; participants obtained 87.8% of the total achievable score for these questions). The knowledge about prevention and control of COVID-19 among participants needs was very high (x=2.77; participants obtained 92.3% of the total achievable score for these questions). Attitude of participants towards the COVID-19 outbreak was positive and above average (x=2.84). However, participants reported that it is hard to get palliatives or financial support from others during COVID-19 lockdown (52.8%) and that they feel frustrated by the uncaring attitude of the government towards them during COVID-19 lockdown (55.6%). On this basis, counselling and social policy implications were suggested including the provision of palliatives by the government and the need for widespread enlightenment among individuals with special needs on prevention of COVID-19.

Abstract

Purpose

This study was carried out to examine the volume and annual growth pattern of research on e-health literacy research, investigate the open-access types of e-health literacy research and perform document production by country and by sources. The study also mapped the keywords used by authors to represent e-health literacy research and performed an analysis of the clusters of the keywords to reveal the thematic focus of research in the area.

Design/methodology/approach

The research was guided by a bibliometric approach involving visualization using VosViewer. Data were sourced from Scopus database using a syntax that was tested and verified to be capable of yielding reliable data on the subject matter. The analysis in this study was based on bibliographic data and keywords.

Findings

A total number of 1,176 documents were produced during 2006 and 2022. The majority of the documents (18.90%) were published based on hybrid open-access processes, and the USA has the highest contributions. The Journal of Medical Internet Research is the venue for most of the documents on the subject. The 1,176 documents were described by 5,047 keywords, 4.29 keywords per document, and the keywords were classified into five clusters that aptly capture the thematic structure of research in the area.

Research limitations/implications

e-Health literacy has experienced significant growth in research production from 2006 to 2022, with an average of 69 documents per year. Research on e-health literacy initially had low output but began to increase in 2018. The majority of e-health literacy documents are available through open access, with the USA being the leading contributor. The analysis of keywords reveals the multifaceted nature of e-health literacy, including access to information, attitudes, measurement tools, awareness, age factors and communication. Clusters of keywords highlight different aspects of e-health literacy research, such as accessibility, attitudes, awareness, measurement tools and the importance of age, cancer, caregivers and effective communication in healthcare.

Practical implications

This study has practical implications for health promotion. There is also the element of patient empowerment in which case patients are allowed to take an active role in their healthcare. By understanding their health information and having access to resources that help them manage their conditions, patients can make informed decisions about their healthcare. Finally, there is the issue of improved health outcomes which can be achieved by improving patients' e-health literacy. Visualisation of e-health literacy can help bridge the gap between patients and healthcare providers, promote patient-centered care and improve health outcomes.

Abstract

Purpose

This purpose of this study was to assess dietary diversity among women of reproductive age (WRA) and the associations between consumption of a diversified diet and overweight/obesity statuses in Ekiti State, Nigeria.

Design/methodology/approach

Cross-sectional study of 207 WRA from six local government areas in Ekiti State, Nigeria, was done. A validated interviewer-administered questionnaire was used to collect data on sociodemographic characteristics, dietary intake and anthropometry. Dietary intake was assessed with 24-h dietary recall to calculate the Minimum Dietary Diversity Score for Women (MDD-W). Data were analyzed using descriptive statistics, Spearman rank correlation and Chi square test at α0.05.

Findings

Majority of the participants (65.2%) were aged between 19 and 34 years, 58.5% were married and 49.8% had high school as their highest level of education. Mean MDD-W and body mass index (BMI) were 3.8 ± 0.9 and 25.46 ± 6.4 kg/m2, respectively. All participants (100%) consumed foods from the “grains, white roots and tubers” group and majority also from the “meat and poultry” group (79.7%) but ranked low in the consumption of foods from other food groups. Many were overweight (34.8%), obese (14.0%) and a few (1.9%) had morbid obesity. MDD-W was significantly associated with marital status (X2 = 7.7, P = 0.022) and BMI (X2 = 11.4, P = 0.023) and had a weak positive correlation with BMI (r = 0.189, P = 0.007).

Research limitations/implications

Study shows that both undernutrition and overweight/obesity coexist in the population, indicating a case of double burden of malnutrition (DBM) at a population level. However, further studies may be needed to investigate the extent of DBM at individual levels. Although there was a positive correlation between MDD-W and BMI, it cannot be used to predict causality. Study further reveals that the micronutrient intake of the WRA population in Ekiti is inadequate. Considering the importance of the 10 food groups highlighted in MDD_W to nutrition and health, the promotion of the consumption of foods from these food groups with more attention to the micronutrient-rich ones needs to be heightened.

Originality/value

Diet of participants was not diverse enough, indicating micronutrient inadequacy. Promotion of the consumption of a diverse diet, particularly from the food groups rich in micronutrient, needs to be heightened, while food groups high in calorie should be minimally consumed to forestall DBM.

Abstract

Purpose

This paper aims to report a non-randomized control study undertaken to investigate prevalence and correlates of conduct disorder among male secondary education students in South-West Nigeria and to assess the impact of a problem-solving skills and attributional retraining (PSSAR) intervention with this population.

Design/methodology/approach

In total, 787 male students from two schools were screened for conduct disorder. All participants who met criteria for the disorder were allocated to either treatment (n = 55) or control (n = 47) groups. Outcome measures comprised the strengths and difficulties questionnaire (SDQ; teacher and student versions) and the teacher rating of students’ aggressive behaviors.

Findings

Of the sample, 13% were found to present with difficulties that met criteria for conduct disorder. The presence of these difficulties correlated with several demographic variables, including parental conflict and alcohol use. A statistically significant reduction in mean scores was observed for the treatment group in the student rating of the SDQ emotional subscale and total difficulties scores. Teacher ratings were less consistent in that conduct problems, prosocial behavior and total difficulties increased following the intervention, whereas peer problems and aggressive behavior were reported by teachers to reduce. No statistically significant change was found in the outcome measures for the control group.

Practical implications

In resource-constrained settings, school-based interventions are an important means through which treatment gaps in child and adolescent mental health can be addressed.

Originality/value

In resource-constrained settings, school-based interventions are an important means through which treatment gaps in child and adolescent mental health can be addressed. This study’s findings offer some preliminary support for the PSSAR intervention for conduct disorder in this context and indicate areas for further research.

This study assessed the heterogeneous impact of the Anchor Borrower Program (ABP) on the welfare distribution of rice farming households in Nigeria.

Abstract

Purpose

This study assessed the heterogeneous impact of the Anchor Borrower Program (ABP) on the welfare distribution of rice farming households in Nigeria.

Design/methodology/approach

Self-selection bias and treatment endogeneity were accounted for by employing the Instrumental Variable Quantile Regression (IVQR) model. The estimates obtained from the IVQR model were further compared with those from the conventional quantile regression, and quantile regression using Propensity Score Matching. This was to highlight the extent to which endogeneity bias has been purged from the treatment, in order to establish a consistent causal link between participation in the ABP and the welfare of a cross-section of rice farming households.

Findings

ABP farmers had significantly higher rice yields across all quantiles of the yield distribution under treatment exogeneity assumption, and in only two quantiles upon controlling for observable confounders. However, this yield gain did not translate to higher Per capita Consumption Expenditure (PCE). The estimates of the more robust IVQR model provided further evidence that the rice yield and PCE of ABP farmers are not statistically different from that of non-ABP farmers across all quantiles of the welfare distribution.

Social implications

The negligible impact of ABP was relatively higher for lower-yielding households. Thus, implying that, although the ABP is a pro-poor development intervention, the program has not been sufficiently implemented to significantly improve the welfare of the dominant resource-poor farming households in Nigeria.

Originality/value

This study assessed the impact of ABP beyond the conventional potential mean outcome framework by accounting for heterogeneity in treatment effect.
