- Description: Abstract: University professional and teaching staff are like two sides of the same coin. However, to a great extent, they work in silos – which leads to fragmentation and undermines efforts to achieve significant levels of impactful, sustainable and holistic student success. In this context, this special issue was proposed as a contribution towards closing the gap between the academic part of the university and the professional or support-services part; and as a means of encouraging the work required to forge integrated approaches in support of enhanced student success. The siloed approach, which is indicative of the politics and potential power dynamics that are embedded in university operations and structures, needs to be dismantled...

- Description: Background: This study examined Nigeria’s socio-demographic profiles and health service utilization patterns of Patent Medicine Vendors (PMVs) and Community Pharmacists (CPs). Method: A cross-sectional study using a structured self-administered questionnaire among 405 retail outlets (322 PMVs and 83 CPs) across 16 Lagos and Kebbi Local Government Areas (LGAs) between June 2020 and December 2020. Results: Results showed that 60.4% were male, 76.3% from Lagos, 58.3% had tertiary education, and 74.1% had medical training. Cough and fever were common symptoms. Significant differences were found in the utilization of STD services (PMVs: 9.2%, CPs: 12.3%, p = 0.03)), services by age < 0.001), and utilization by males (PMVs: 50.8, CPs: 47.1, p = 0.013). The study revealed that men visited PMVs more, while CPs used more STI services and childhood visits. Conclusions: The findings suggest that expanding health services among PMVs could target male-dominant diseases, and capacity building of CPs on syndromic STI management could reduce the STI burden.

- Description: (1) Background: Patients who deserve intensive care unit (ICU) admission may be denied due to a lack of resources, complicating ICU triage decisions for intensive care unit (ICU) clinicians. Among the resources that may be unavailable are trained personnel and monitored beds. In South Africa, the distribution of healthcare resources is reflected in the availability of ICU beds, with more ICU beds available in more affluent areas. Data on ICU refusal rates, reasons for refusal, patient characteristics, and outcomes are scarce in resource-constrained rural settings. Hence, this study sheds light on the ICU refusal rates, reasons for refusal, characteristics, and outcomes of refused patients at NMAH. (2) Methods: This was a three-month retrospective cross-sectional record review of refused and admitted patients from January to March 2022. COVID-19 patients and those younger than 13 years old were excluded. Refusal rates, reasons for refusal, characteristics, and outcomes of refused patients were analysed quantitatively using SPSS VS 20 software. Reasons for refusal were categorised as “too well”, “too sick”, and “suitable for admission but no resources”. (3) Results: A total of 135 patients were discussed for ICU admission at NMAH during the study period; 73 (54.07%) were refused admission, and 62 (45.92%) were admitted. Being considered too sick to benefit from ICU was the most common reason for refusal (53.23%). Too well and no resources contributed 27.42% and 19.35%, respectively. Patients with poor functional status, comorbidities, medical diagnoses, and those referred from the ward or accident and emergency unit rather than the operating room were more likely to be refused ICU admission. Refused patients had a seven-day mortality rate of 47%. (4) Conclusions and recommendations: The study found an unmet need for critical care services at our institution, as well as a need for tools to help clinicians make objective triage decisions for critically ill patients. Therefore, the study suggests a need to improve the quality of services provided outside of the ICU, particularly for patients who were refused ICU admission, to improve their outcomes.

- Description: The available evidence indicates a correlation between owning consumer electronics, such as cellphones and televisions, and a higher risk of obesity and increased adiposity. However, such studies are sparse in South Africa. Thus, the aim of this study is to examine the dietary and sociodemographic factors associated with various BMI categories, including the possession of consumer electronics, among women of reproductive age in South Africa. This is a secondary study of a population registry that includes dietary, BMI, and digital use items among women of reproductive age. The data is from the South Africa Demographic Health Survey (SADHS, 2016). Of the 3363 participants included in the analysis, women of normal weight were (35.5%), pre-obese (34.5%), obese (27.1%) and underweight (2.9%).

- Description: Zn2V2O7 phosphor was made using a sol-gel technique and then annealed at temperatures ranging from 700 to 850 ◦C. The x-ray diffraction (XRD) results revealed that Zn2V2O7 exhibits a single monoclinic phase. The width at half-maximum of the (022) XRD peak shrank overall resulting in improved crystallinity of the Zn2V2O7 phosphors with higher annealing temperatures. Because of the good crystallinity of Zn2V2O7, scanning electron microscopy (SEM) indicates that grain size increases as the annealing temperature rises. When the temperature was raised from 35 ◦C to 500 ◦C, TGA findings revealed a total weight loss of approximately 65%. The photoluminescence emission spectra of annealed Zn2V2O7 powders revealed a wide green-yellowish emission in the range of 400 nm–800 nm. As the annealing temperature was raised, the crystallinity improved, resulting in an increase in PL intensity. The peak of the PL emission shifts from green to yellow emission.

- Description: These days, aquatic (fish) welfare is a major issue and a significant component that affects fish output. Although numerous factors can be involved, climate-induced floods are one of the most critical limiting factors in the aquaculture and fisheries industry’s development. Understanding the extent of losses and damages caused by floods at the farm level will thereby exacerbate pre-emptive policy responses. Thus, the impact of floods on fish production by focusing on catfish earthen pond-based farmers in Southwest Nigeria is presented. A survey is conducted for 150 fish farms in the region. A marginal treatment effects (MTE) approach is employed to determine the heterogeneity across the households and the policy-relevant treatment effects (PRTE). The results show significant heterogeneity in the effects of floods on fish production, considering both observed and unobserved characteristics of the farmers. It is shown that flood significantly increases output loss. Furthermore, farmers with high propensity scores to flood tend to have a high likelihood of incurring output loss. The estimates of PRTE reveal that relaxing policy strategies, such as access to climate information and climate-related training and workshops, would significantly exacerbate output loss due to flood incidences. Thus, intensifying awareness and sensitization on climate change policies will address the flood menace and still increase food production.

- Description: Abstract The study examined the impact of Sustainable Tax Revenue and Expenditure on the achievement of Sustainable Development Goals in African countries using secondary data. The dataset was extracted from the World Development Indicators database. The large gap between developed and developing countries when comparing the probability of them achieving the SDGs was the main motivation behind this study. Data retrieved from 45 countries comprised of both African and developed countries for the period 2010–2020 was analyzed using the Generalized Method of Moments technique. The results revealed that the coefficients of grants received, various forms of taxes, and other revenue have a positive effect on economic growth but a negative effect on poverty and unemployment for African and developed countries. This finding suggests that improvements in tax revenue generation, grants and other revenue accumulation across different sources boost economic performance and the welfare of individuals in the analyzed countries. The outcome is an indication that accumulating more grants from different sources will help to achieve sustainable development, improve financial stability, contributes to the economic growth and development in these countries. This study can guide policymakers, governments, international institutions, revenue bodies such as SARS and other stakeholders in their various planning and other decision-making endeavors. Governments and other policymakers must ensure the efficient generation and sustainable utilization of revenue generated from taxes and other revenues to spur the growth and development of their countries. They should have Growth-Sustainability-Oriented Fiscal Adjustment Programs and Sustainable Government Expenditure that can help push and redirect governments to achieve the SDGs in Africa.

- Description: Agricultural waste is enriched with a variety of environmentally friendly materials that can potentially boost economic growth, reduce the spread of contagious diseases, and serve as a carbon-free renewable energy bioresource. Biopolymers produced from agricultural waste have a range of applications in medicine, agriculture, pharmaceutics, and industrial factories. The chemical extraction of biopolymers from biomass requires a series of alternating alkali, acid, and alkali treatments at controlled temperatures. Chemical extraction of plant-based biopolymers requires elevated temperatures (70–100°C), while for animal and sea organism-based biopolymers, moderate temperatures of 25–60°C are used. The obtained biopolymers are functionalized into various materials for application in a wide range of industries. The reported functional materials are loaded with inorganic nanomaterials, plant extracts, and organic compounds, which resulted in a synergistic effect and enhanced activity of the materials. Several researchers have synthesized biopolymers with synthetic polymers to improve their bioavailability, tensile strength, shelf life, and UV adsorption. This review article reports the extraction techniques of biopolymers from agricultural waste and their application in wound healing, water treatment, food storage, passive cooling, and cosmetics. The dearth of scientific articles on the applications of biopolymers generated from agricultural waste produced from food crops grown in Africa is a motivation for the present compilation.

- Description: In the present study, a nanocomposite was prepared for the removal of dye from the aqueous phase. In this regard, multiwalled carbon nanotubes (MWCNTs) were anchored on the stalk of Solanum melongena (SMB) to obtain a robust adsorbent with the capacity to eliminate reactive blue 19 (RB19) using the batch adsorptive processes. Solanum melongena stalk decorated with MWCNTs (SMC) and SMB were characterized using Thermogravimetric analysis (TGA), Brunauer–Emmett– Teller (BET), Field emission scanning electron microscopy (FESEM) and Fourier transform infrared spectroscopy (FTIR) analysis. With the exception of solution pH, an increase in contact time, adsorbent dose, initial RB19 concentration, and solution temperature were noticed to elevate the uptake potential of SMB and SMC. Kinetic experimental data for SMB and SMC were consistent with the pseudo-second-order and Elovich model, respectively. The experimental isotherm data obtained for SMB and SMC were best expressed by Freundlich and Langmuir models, respectively. After the fifth adsorption–desorption cycle, SMC exhibited 52% of adsorption efficiency. Hence, SMC can be an auspicious candidate for the efficient adsorption of RB19.

- Description: Discretionary accruals remain decade’s long measures to detect earnings management in empirical accounting research. The correctness of the specifications and test power of the information content for the models remains unexplored based on samples of most emerging market firms. Yet, country’s-based researchers have increasingly used different Jones-based discretionary accruals to proxy earnings management. The paper aims to evaluate four discretionary accruals models and to decide the most appropriate one for the detection of earnings management. For the aim, we apply regression methods to estimate and evaluate four Jones-type discretionary accruals models – simple Jones, modified Jones, extended Jones cash flow model and working capital accruals – based on evidence of a final sample of 1,852 firm-year of 102 firms in Nigeria during 2001–2020. The results disclose that all models are well-specified such that the likelihood of Type I errors is minimum and below the significance level of 5%. In order to demonstrate the power of the test, the simulations completed identify that the modified Jones model exhibits the highest power capability. The implication of this finding is that the modified Jones model is the most appropriate model to detect earnings management based on the Nigerian sample.

- Description: Discretionary accruals remain decade’s long measures to detect earnings management in empirical accounting research. The correctness of the specifications and test power of the information content for the models remains unexplored based on samples of most emerging market firms. Yet, country’s-based researchers have increasingly used different Jones-based discretionary accruals to proxy earnings management. The paper aims to evaluate four discretionary accruals models and to decide the most appropriate one for the detection of earnings management. For the aim, we apply regression methods to estimate and evaluate four Jones-type discretionary accruals models – simple Jones, modified Jones, extended Jones cash flow model and working capital accruals – based on evidence of a final sample of 1,852 firm-year of 102 firms in Nigeria during 2001–2020.

- Description: Background: Globally, the COVID-19 pandemic has had a negative impact on individuals, education, and the economy. During its peak, the pandemic forced school closures. Although there is currently no cure for corona virus, non-pharmaceutical measures can help prevent its spread. Among these preventive measures are regular handwashing with soap and water or the use of hand sanitizers, avoiding touching the mouth, nose, and eyes, social distancing, and the use of face masks. As a result, this study investigated COVID-19 prevention practices among Durban University of Technology staff and students in South Africa. Methods: Using a cross-sectional study design, data were gathered online via self-administered, structured questionnaires from 5849 university students and staff members between May 2020 and March 2021. Utilizing descriptive statistics, the characteristics of the study sample were reported. Using logistic regression models, the relationship between demographic characteristics and the overall level of COVID-19 preventive practices was evaluated. Results: The multivariate logistic regression model showed statistically significantly associations for COVID-19 preventive practices by: male (AOR: 9.815, 95% CI: 1.721–55.959, p = 0.01) compared to female participants, single participants (AOR: 6.012, 95% CI: 2.070–17.461, p = 0.001) compared to other marital categories, and those in the faculty of Health Sciences (AOR: 1.721, 95% CI: 1.023–2.894, p = 0.041) compared to other faculties. Conclusions: Overall, the study’s preventive practices were commendable; they were also influenced by socio-demographic factors such as age, gender, marital status, and university faculty. Increasing age was associated with reduced compliance with COVID-19 preventive practices. In addition, men demonstrated greater caution than women.

- Description: Background: Globally, there is an overwhelming increase in the number of patients waiting for donated organs for transplantation, with a gross shortage of available organs. Lack of clear practice guidelines and the knowledge and attitudes of health care providers were hypothesized as possible reasons. We aimed to determine the attitudes, level of knowledge, and practices of professional nurses working in critical care units in public and private hospitals in Eastern Cape Province regarding organ donation. Method: The study used a quantitative, non-experimental, descriptive design to investigate the current knowledge, attitude, and practice of organ donation in critical care among 108 professional nurses working in public and private critical care units in Eastern cape. Data were collected between 26 February 2017 until 27 June 2017 using anonymous, self-administered, pretested questionnaires. The means of knowledge, and practice scores were estimated among participants, and their associated categorical explanatory variables were ascertained. Results: A total of 108 nurses participated in the study. Of these, 94 (87.0%) were female, 78 (72.2%) were black, 104 (96.3%) were Christians, 79 (73.2%) worked in an ICU, 79 (73.2%) had a diploma qualification, and 67 (62.0%) worked in a tertiary hospital. About 67% of the respondents had good knowledge, 53% had a positive attitude, and 50.4% had poor practice readiness toward organ donation...

- Description: The τ-phase Ba1.3Ca0.7SiO4 alkaline earth silicate powders were synthesized using the solution combustion technique. For this purpose, metal nitrate–urea mixtures were used as anoxidant and a fuel. Urea’s main function was to help lower the nominal combustion temperature (~550 ◦C) of the mixtures through exothermic reactions, leading to a relatively mild post-annealing temperature (~750 ◦C). If the urea concentration increased, the interconnected silicate particle size decreased with nanoscale crystallite (average, 33 ± 3 nm), affecting optical properties. Finally, the photoluminescence spectra suggested that the light emission was through trap sites, because the emitted blue and green lights (2.6 and 2.3 eV, respectively) were smaller than the bandgap (~3.2 eV) of the Ba1.3Ca0.7SiO4 semiconductor.

- Description: Background. Healthcare workers (HCWs) can play a signifi cant role in tobacco prevention by delivering smoking cessation (SC) interventions to patients who smoke. Objective: To identify and explore the perceived barriers which prevent healthcare workers from delivering SC counselling to patients in Zambezi region, Namibia. Methods: A regional-based, concurrent mixed-methods study was conducted between March and October 2020 among HCWs of the 8 constituencies of Zambezi region, Namibia. In the study, 129 respondents, who had been residents of the selected constituencies for over 5 years and aged between 17 to 60 years, participated. Results: 129 respondents participated in the study. Majority of respondents were females (62.9% and 68.1%) compared to (37.1% and 31.9%) males. The mean age of respondents was 35.91 (SD=9.3) and 36.61 (SD=8.7) respectively and their ages ranged between 18 and 59 years. Key barriers were identified: (i) HCWs based barriers included lack of time to provide SC, inadequate training and insufficient knowledge on SC interventions; (ii) sys tem-based barriers identified lack of SC guidelines and educational materials for patients, and specialists to refer patients; and (iii) patient/client-based barriers included lack of patient interest in SC information, patients not adhering to advise given on SC. Conclusions: This study showed that SC delivery in Zambezi region is inadequate. Barriers were identified regarding the deliv ery of SC intervention for the first time. Targeted SC interventions are required to combat these identified specific barriers. There is a crucial need to improve HCWs skills and knowledge in providing SC intervention

- Description: This paper employs a psychosocial framework to analyse the everyday lived experiences of a child and youth care worker in semi-rural South Africa. The aim is to provide a new perspective of care work by drawing on narrative analysis alongside a psychoanalytic approach to qualitative research. With an emphasis on the socially constructed nature of reality, the researcher aims to elucidate the rich unconscious depths of being a care worker and the dynamics of the intersubjective reality of care work. Employing a free association narrative interview technique allows the researcher to gain understanding of the narratives that the care worker draws on in the construction of his identity as a care worker. The use of a psychosocial approach enables the researcher to pay attention to both the social context that influences the narratives that he draws on, but also the psychological ‘pay offs’ of these constructions. Most notably, the study highlights how the care worker’s identity is mediated by a defended subjectivity and argues that his failures in mentalization might stem from the way he is treated as a care worker by other professionals as a result of their mindblindness. This maintains his narrative of invisibility, and the pervasive feeling of being misunderstood as a professional in his own right. The findings are discussed in terms of their contribution to understanding some of the challenges that CYCC care workers face. , Research Article (MA) -- Faculty of Humanities, Psychology, 2022

- Description: Rural Ethiopian communities rely mostly on biomass fuels for subsistence and productive purposes. With an increasing population and dwindling forest resources, wood fuel consumption has exceeded its supply. Besides, people do not know ways of maximising biomass efficiency. The study involves the burning efficiencies of woods with varied moisture contents. Eucalyptus wood of five different moisture contents was used in five identical wood-burning stoves purposefully constructed for this purpose. Tests were con ducted over 5 days, thereby giving five replications. In the tests, food temperature, stove body temperature, and stove smoke outlet temperature measurements were conducted along with ambient air temperatures. Wood with 10% moisture content performs better during combustion with respect to low and high moisture content wood. High moisture content delayed the cooking onset and low moisture decreased the duration of effective cooking. The 50% moisture content or greater with respect to oven-dried wood failed to cook. Moisture content of around 30% delayed the time to reach cooking temperature by two and hence elongated the cooking time. There is also the extended smoke time as observed from the smoke outlet temperature.

Although this phenomenon is well researched, teachers’ experiences of stress remains a worrying challenge particularly to schools’ effectiveness. This study sought to establish how monitoring and management mechanism that can assist teachers to cope with stress challenges. These are some of the recommendation: that the school disciplinary committee should be trained in various disciplinary measures that may be implemented in the school to curb learner ill-discipline and lack of commitment, that working relationship should be built between schools and the Department of Basic Education, motivational speakers and educational counsellors should meet with all learners on a regular basis to motivate them to have high desire for and interest in education and to build their self-confidence in the classroom, providing all the schools with healthy environment in classrooms, provision of learning and teaching materials to all schools, schools should set up an effective school-parents partnership in order to promote a safe drug and alcohol free environment, employ enough teachers in all secondary schools and the Department of Basic Education at district level should make room for stress management workshops for teachers.

- Description: Retraction Watch maintains a "running list" of retracted papers on Covid-19 related research. By the end of September 2020, thirty-three retracted Covid-19 papers were listed. We analysed these retracted papers, focusing specifically on how they have been cited by review papers, and subsequently how they have penetrated and potentially distorted public discourse and legitimate research on Covid-19. The study demonstrates the need for more in-depth studies that focus on the phenomenon of citation pollution. We show that the "Covid-19 publication race", amplified by a pressure-to-publish research culture, distorted published science on Covid-19. We highlight the urgency to engage popular media and critical decision makers on how to distinguish between questionable and legitimate science. We also emphasise the importance of dealing with illegitimate research in a timely manner, both from a scholarly communications and research quality perspective. , Retraction Watch maintient une "liste courante" des articles rétractés sur les recherches liées au Covid-19. Fin septembre 2020, trente-trois articles rétractés sur le Covid-19 étaient répertoriés. Nous avons analysé ces articles rétractés, en nous concentrant spécifiquement sur la façon dont ils ont été cités par d'autres articles, et ensuite sur la façon dont ils ont pénétré et potentiellement faussé le discours public et la recherche légitime sur le Covid-19. L'étude démontre le besoin d'études plus approfondies qui se concentrent sur le phénomène de la pollution des citations.

- Description: Retraction Watch maintains a "running list" of retracted papers on Covid-19 related research. By the end of September 2020, thirty-three retracted Covid-19 papers were listed. We analysed these retracted papers, focusing specifically on how they have been cited by review papers, and subsequently how they have penetrated and potentially distorted public discourse and legitimate research on Covid-19. The study demonstrates the need for more in-depth studies that focus on the phenomenon of citation pollution. We show that the "Covid-19 publication race", amplified by a pressure-to-publish research culture, distorted published science on Covid-19. We highlight the urgency to engage popular media and critical decision makers on how to distinguish between questionable and legitimate science. We also emphasise the importance of dealing with illegitimate research in a timely manner, both from a scholarly communications and research quality perspective. , Retraction Watch maintient une "liste courante" des articles rétractés sur les recherches liées au Covid-19. Fin septembre 2020, trente-trois articles rétractés sur le Covid-19 étaient répertoriés. Nous avons analysé ces articles rétractés, en nous concentrant spécifiquement sur la façon dont ils ont été cités par d'autres articles, et ensuite sur la façon dont ils ont pénétré et potentiellement faussé le discours public et la recherche légitime sur le Covid-19. L'étude démontre le besoin d'études plus approfondies qui se concentrent sur le phénomène de la pollution des citations.
