Full textAbstract:
One major problem in Africa in general is to convince governments and agencies that astronomy is relevant to Africa. Attention has been focussed on technology transfer, neglecting science and research. This attitude encourages the continued dependence on industrialized countries.In Nigeria there has been some success in projecting the idea that Space Science does not just mean remote sensing, but that basic space science, i.e. astronomy and astrophysics, cosmology, planetary science etc. is important and necessary. Evidence of this is that Nigeria’s expert committee on space policy recommended that one of three proposed National Centres should be for basic space science, laying emphasis on fundamental physics, astronomy and astrophysics, solarterrestrial interactions and their influence on climate, planetary and atmospheric studies. In addition, the Government of Nigeria hosted the Third UN/ESA Workshop on Basic Space Science in October, 1993.

"Investigating Digital Distraction among Pre-service Science, Technology, and Mathematics Teachers in Nigeria." Digital Education Review, no. 37 (June 30, 2020): 32–48. http://dx.doi.org/10.1344/der.2020.37.32-48.
Full textAbstract:
Internationally, proliferation of digital technologies in classrooms has produced digital distractions among digital natives in this 21st century. Thus, it is highly imperative to develop a suitable instrument for assessing and measuring digital distraction among higher education students to enable continuing research and practice. While previous studies had treated and measured digital distraction as a sub-component of a multi-dimensional construct and as a test, the present study through instrumentation survey research, developed and authenticated a standalone digital distraction scale among pre-service science, technology and mathematics (STM) teachers in Nigeria. The instrument is constructed by adopting a multidimensional standpoint of digital distraction around a higher-order modelling method. The pre-service STM teachers were recruited from a culturally varied university student population in Nigeria. The results showed a high level of digital distraction among the pre-service STM teachers in Nigeria and the digital distraction is composed of several connected yet distinctive factors (emotional distraction, digital addiction, and distraction by procrastination), with proof backing up a higher-order structural archetypal. More so, empirical evidence confirmed the measurement invariance of the scale with regards to gender and the consistency of the psychometric properties of the digital distraction scale. Finally, a test-retest reliability of the digital distraction scale showed that the scores are not variable over time and that the scale is not sensitive to alterations in the learning milieu. Finally, it is hoped that this tool will be handy for educators interested in isolating pre-service STM teachers at risk of high digital distraction which may cause lack of respect and privation of courtesy for instructors and personal distraction in the classroom.

Full textAbstract:
Primary data collected over a wide area in Africa show that average cassava root yield is not declining as the population increases because the land is being cultivated more intensively in response to demographic pressures. Although fallow periods are becoming shorter, organic manuring, improved market infrastructures and the use of purchased inputs such as labour compensate for this. The yields of improved cassava varieties in Nigeria show that technology can be relied upon to raise production in future, provided that the conditions necessary for the widespread adoption of Improved varieties prevail in most African countries.

Recently, intensification of both rain-fed and dry-season irrigated agriculture has necessitated widespread use of pesticides in the extensive sub-humid zones of Nigeria. In this region is located over 80% of Nigeria's existing surface area of reservoirs in the country. The majority of these reservoirs were built artificially for a multiplicity of uses among which fisheries and Nature conservation ranked very high.—

Full textAbstract:
Purpose – In this study, the authors aim to understand the antecedents of technology adoption in Sub-Saharan Africa by investigating the relationship between people's economic status, their positive attitudes, and the adoption of communications technology. Design/methodology/approach – The authors used data obtained from the Gallup World Poll that was conducted in 2008. The Gallup World Poll is a survey of residents in more than 150 countries. Based on a sample of 8,787 in Kenya, Ghana and Nigeria, the authors used SEM to test the hypotheses. Findings – Hierarchical regression analyses revealed that economic status significantly predicts both positive attitudes and technology adoption. Further, the authors found that infrastructure development moderates the relationship between economic status and technology adoption. Originality/value – The study attempts to plug the gaps in established theories of technology adoption which typically do not take into consideration factors that are peculiar to LDC contexts.

Full textAbstract:
The technology of glassmaking is complex. This complexity has been cited for the exclusion of the development of ancient glass technology from certain regions of the world, especially Africa, South of the Sahara. Thus, much of the existing scholarship on the technology of ancient glass has focused on the Middle East, Mediterranean, and Southeast and South Asia. Although the discourse on indigenous African technology has gained traction in Black studies, the study of ancient glass seems to have been left mainly in the hands of specialists in other disciplines. Drawing from archaeological and historical evidence from Ile-Ife, Southwest Nigeria, in tandem with the result of compositional analysis, this article examines the first recognized indigenous Sub-Saharan African glass technology dated to early second millennium ad or earlier. The development of the local glass recipe and the making of beads not only ushered in a social, religious, and economic transformation in Yorubaland as well as the other West African societies but also redressed the place of Sub-Saharan African in the historiographical map of ancient global technology and commerce.

Full textAbstract:
Most of the studies on IT personnel turnover intentions were carried out in the developed countries. Only a few researchers have focused on developing countries. The authors' study makes a comparative study of IT personnel turnover intentions in two sub-Saharan African countries (Botswana and Nigeria) using the Igbaria and Greenhaus turnover model. The intent was to find out if the same model elements affect turnover intentions in the two countries. The results show that demographic variables (age and length of service), the role stressors (role ambiguity and role conflict), the career related variables (growth opportunity, supervisor support and external career opportunities), job satisfaction and career satisfaction have direct effect on turnover intentions in these two developing countries, while other affectors in the research model do not hold equally for the two countries, except for growth opportunity.

Full textAbstract:
The fundamental importance of groundwater for urban drinking water supplies in sub-Saharan Africa is increasingly recognised. However, little is known about the trends in urban groundwater development by individual households and its role in securing safely-managed drinking water supplies. Anecdotal evidence indicates a thriving self-supply movement to exploit groundwater in some urban sub-Saharan African settings, but empirical evidence, or analysis of the benefits and drawbacks, remains sparse. Through a detailed analysis of official datasets for Lagos State, Nigeria we examine the crucial role played by groundwater and, specifically, by household self-supply for domestic water provision. We then set this in the context of Nigeria and of sub-Saharan Africa. One of the novelties of this multi-scalar approach is that it provides a granular understanding from large-scale datasets. Our analysis confirms the importance of non-piped water supplies in meeting current and future drinking water demand by households in parts of sub-Saharan Africa and the role played, through self-supply, by groundwater. Our results demonstrate inconsistencies between datasets, and we make recommendations for the future. We argue that a key actor in the provision of drinking water supplies, the individual household, is largely overlooked by officially reported data, with implications for both policy and practice.

Full textAbstract:
Water infrastructure development is key to attaining sustainable development, especially for water supply, sanitation and health, agricultural development, and energy production. However, sub-Saharan African countries face specific challenges around infrastructure financing, systemic and repeated malfunctioning, and decentralised infrastructure types. Using Nigeria as a case, this article aims to analyse historical water infrastructure development in Nigeria with a specific focus on dams and standpipes. Seven themes are discussed: infrastructure divisions; deprioritising water supply; political infrastructures; infrastructure failure and sustainability; infrastructure classification and typologies; optimal use of water resources and infrastructure; and a commentary on the future of water infrastructure development. The article concludes with policy and research suggestions for policymakers and other relevant stakeholders.

Full textAbstract:
A general belief is that Mobile Money (mMoney) has the catalytic effect of spurring mCommerce growth and driving financial inclusion in developing nations like Nigeria. In Nigeria, mMoney service is certainly a new financial service innovation in the country, and as a result critical issues surrounding its early critical mass adoption, including its perceived usefulness, remain largely opaque. In this paper, our aim was to explore factors influencing perceived usefulness of mMoney by using the extended technology acceptance model (TAM) as the theoretical underpinning of our work. This work is based on a usable sample of 127 respondents from two major cities in Nigeria. Overall, the study’s results indicate that perceived regulator assurance, service affordability, convenience, proximity to the nearest bank branch, and worry over ease of use are significant predictors of mMoney perceived usefulness. The work helps shed new insights about the significant factors that are closely related to the consumer’s perception of the relevance of mMoney services (to his/her financial needs). In sum, the study is an initial step to addressing the issue of perceived usefulness of mMoney service, including its pivotal importance to laying a solid foundation for mCommerce growth in Nigeria and similar sub-Saharan African (SSA) coun-tries.

Full textAbstract:
<p>Soils of the southern Guinea savanna zone of Nigeria are inherently infertile due to shortened fallow period and the continuous use of inorganic fertilizer which depletes the soil of micronutrients such as zinc over time. A field trial was carried out at the Teaching and Research Farm of the University of Ilorin, Nigeria during the 2016 and 2017 cropping seasons to evaluate the effect of zinc and NPK fertilizer on the growth, yield and zinc concentration of seeds of sesame. The experiment was laid out as a factorial fitted into a randomized complete block design (RCBD), replicated thrice. The treatment consisted of four levels of ZnSO<sub>4</sub> (0, 5, 10 and 15 kg ha<sup>-1</sup>) and four levels of NPK 15:15:15 (0, 100, 200 and 300 kg ha<sup>-1</sup>). Data collected were subjected to analysis of variance (ANOVA) and means were separated using new Duncan multiple range test at 5 % level of probability. Results obtained showed significant effects of Zn and NPK rates on plant height, number of leaves, yield per plot and yield per hectare. The application of 15 kg ha<sup>-1</sup> Zn and 300 kg ha<sup>-1</sup> (15:15:15) NPK resulted in high yield and high zinc content of seeds.</p>

Full textAbstract:
This study was carried out to determine the frequency and antibiotic susceptibility profile of bacterial agents associated with diabetic patients attending out-patients Department in Plateau Specialist Hospital Jos. Wound swabs and pus were collected from the wounds of 251 out-patients’ department (OPD) over a 14 months’ period. Subjects were recruited upon approval by the Ethical Research Committee of the UCTH and after obtaining written or oral informed consent from the subject. Samples were cultured and microbial isolates identified using standard microbiology methods. Antibiotic susceptibility testing was carried out on the bacterial isolates. Six bacterial isolates were identified from wounds of diabetic patients viz: Escherichia coli, Proteus mirabilis, Staphylococcus aureus, Streptococcus pyogenes, Pseudomonas aeruginosa, and Klebsiella pneumoniae. The most frequently encountered bacterial pathogen of wound infection among subjects was Pseudomonas aeruginosa (26.67%) followed by Staphylococcus aureus (23.33%) while the lowest was Klebsiella pneumonia (6.67%). The antibiotic susceptibility profile of the bacterial isolates to commonly used antibiotics ranged between 0.0% to 100%. The flouroquinolones were the most active antimicrobial agents observed among bacterial isolates from diabetic out-patients studied. S. aureus [7(100%) and 6(85.7%)] was the highest susceptible bacteria followed by P. aeruginosa [7(87.5%) and 5(62.5%)], E. coli 6(100%) against Ciprofloxacin (10%) and Augmentin (30%) respectively. Meanwhile, K. pneumonia and S. pneumonia were not susceptible each (0.0%) against Doxycycline and Chloramphenicol at 10% and 30% concentrations respectively. The study showed a high index of wound contamination with bacteria pathogens and resistance pattern to standard and commonly used antibacterial agents among diabetic out-patient from the study area.

Full textAbstract:
It is a great pleasure to introduce the second volume second issue of our journal into the global community yearning for high-quality, impactful papers. IPJAF continues to seek and provide readers throughout the world with technology supported peer-reviewed scholarly articles on a broad range of established and emergent areas of accounting, finance, business, economics, and social sciences.
I am resolute to maintain the high-quality standard of research and publication which is anchored on the exemplary service and dedication of our editorial board, editorial review and the editorial office. This volume 2, issue 2 comprises five manuscripts dealing with financial accounting, taxation, and auditing.
The first article entitled “Examining the independent audit committee, managerial ownership, independent board member and audit quality in listed banks” by Dr. Hisar Pangaribuana (Adventist University of Indonesia, Bandung, Indonesia), Dr. Jenny Sihombinga (Adventist University of Indonesia, Bandung, Indonesia), and Dr. Oluwatoyin Muse Johnson Popoola (Tunku Puteri Intan Safinaz School of Accountancy, College of Business, Universiti Utara Malaysia) examines the effects of the independent audit committee on the relationship between managerial ownership and independent board member on audit quality in the Indonesian listed banks. The unit of analysis is companies carrying on the banking business and listed on the Indonesian stock exchange (IDX) between the period of 2010 to 2015. This study is explanatory (i.e., causal predictive), and uses the second generation structural equation modelling statistical analysis tools, PLS-SEM and PROCESS Partial Least Square for hypotheses testing. The results show that the independent board member has a significant impact on the independent audit committee and the audit quality. The study reveals that managerial ownership does not influence audit quality. The adoption of the independent audit committee with a long tenure of years can be potentially risky and less creative. As a result, their oversight functions may be in jeopardy, impaired or reduced performances. The research findings reveal no significant indirect effects of the independent audit committee on the relationship between managerial ownership, independent board member and audit quality in the banks listed in IDX. Independent board members need to renew the appointment of the independent audit committee members to improve the quality of the oversight functions undertaken by the audit committee, and hence, enhance audit quality. The authors suggest further research on the ideal level of managerial ownership and number of an independent board member to produce a good audit quality in the Indonesian listed banks.
The second article titled “Salaried taxpayers’ internal states and assessment performance under self-assessment system: a quasi-experimental evaluation” by Dr. Noraza Mat Udin (Tunku Puteri Intan Safinaz School of Accountancy, College of Business, Universiti Utara Malaysia) takes a look at the first reform that impacts taxpayers, that is, the implementation of self-assessment system (SAS) to replace the old assessment system in 2004. The perception is that SAS had entirely changed the taxpayers’ responsibilities from being assessed by the tax authority to a person who is responsible for assessing own income tax liability. Her study explores the public fora debates on whether taxpayers can perform their responsibilities that were previously handled by trained tax personnel in Malaysia. Her paper reports the findings of a quasi-experimental evaluation of salaried individual taxpayers’ in the early stage of SAS implementation. She argues that a lot needs to be done, notwithstanding SAS had been implemented for more than a decade, the problem of taxpayer performance is continuing due to the dynamic nature of taxation in reality. The data were collected using a quasi-experimental method known as posttest-only no-treatment control group design. The sample comprised post-graduate students, who were actual taxpayers. Among the elements of the taxpayer’s internal states considered in this study, tax knowledge was found to have a significant relationship with assessment performance. Further analysis was conducted which showed that the majority of tax knowledge dimensions had a significant relationship with taxpayer assessment performance. The findings of this study have contributed to the body of knowledge because there is a general dearth of published research, particularly in Malaysia that investigates taxpayer assessment performance especially using an experimental approach.
The third article with a caption, “Working capital management and firm performance: lessons learnt during and after the financial crisis of 2007-2008 in Nigeria” by Mr. Sunday Simon (Tunku Puteri Intan Safinaz School of Accountancy, College of Business, Universiti Utara Malaysia), Dr. Norfaiezah Sawandi (Tunku Puteri Intan Safinaz School of Accountancy, College of Business, Universiti Utara Malaysia), and Prof. Dr. Mohamad Ali Abdul-Hamid (Department of Accounting, College of Business Administration, University of Sharjah, United Arab Emirate) examines the relationship between working capital management (WCM) and firm performance during and after the financial crisis of 2007-2008 in Nigeria. The authors argue that the financial crisis could be attributable to the deterioration and ultimate failure of WCM performance that affected many Nigerian firms. During the crisis, lending conditions were deeply affected, and financing operations became challenging for firms. Although research findings on the causes and effects of the crisis on the economy are known, what remains unknown is whether the financial crisis had a significant impact on WCM performance. The differences between the two periods, the crisis period and then after the crisis period, is operationalised through two analyses. The findings indicate that WCM variables have more explanatory power (R2) in the period after the crisis than during the crisis. Also, the results of the Cramer Z-statistic, which examined between sample comparisons of the R2, revealed that the Z-scores are significant, implying that a significant difference existed between the two periods. It suffices to say that WCM was affected during the financial crisis and led to low profitability, whereas, during the after-crisis period, WCM associates with higher profitability. These findings have implications for managers and policymakers because access to financing has become a global problem and adequate WCM management increases a company’s resilience to financial and external shocks.
The fourth article entitled “The Influence of Technology Readiness on Information Technology Competencies and Civil Conflict Environment” by Prof. Dr. Kamil Md. Idris (Tunku Puteri Intan Safinaz School of Accountancy, College of Business, Universiti Utara Malaysia), Associate Prof. Dr. Akilah Abdullah (Tunku Puteri Intan Safinaz School of Accountancy, College of Business, Universiti Utara Malaysia), Haetham H. Kasem Alkhaffaf (OYA Graduate School of Business, College of Business, Universiti Utara Malaysia), and Al-Hasan Al-Aidaros (Islamic Business School, Universiti Utara Malaysia, Malaysia). Their study confirms prior findings that the Technology Readiness scale can capture the association among technology readiness and technology usage behaviours. The study also expands earlier research by investigating the impact of technology readiness on individual competency among accountants to using IT in a workplace under the intensity of civil conflict in Iraqi environment. The result shows that there is a positive significant relationship between technology readiness and the IT competencies of Iraqi accountants. It implies that the technology readiness regarding willingness, enthusiasm, and motivation of accountants using IT has an impact on their IT competencies. In other words, the higher the readiness of the accountants in making use of technology, the higher their competence in the use of IT. This study contributes to the body of knowledge in terms of theory, method and practice in Iraq especially and developing countries in general.
The fifth article titled “Mediating effect of Quality-differentiated Auditor on the relationship between Managerial ownership and Monitoring mechanisms” and authored by Dr. Rachael Oluyemisi Arowolo (Chrisland University, Nigeria), Prof. Dr. Ayoib Che-Ahmad (Tunku Puteri Intan Safinaz School of Accountancy, College of Business, Universiti Utara Malaysia), Dr. Oluwatoyin Muse Johnson Popoola (Tunku Puteri Intan Safinaz School of Accountancy, College of Business, Universiti Utara Malaysia) and Dr. Hisar Pangaribuana (Adventist University of Indonesia, Bandung, Indonesia) examines the relationship between Managerial Ownership (MO) and MMs with quality-differentiated auditors (QDA) as the channel for the relationship. Over the past decade, most studies in corporate governance and audit market emphasised the importance of monitoring mechanisms (MM), especially after the global economic meltdown resulting from the Enron saga. The literature on MM continues growing as many countries especially the Sub-Saharan Africa are still struggling to come out of the effect of the economic meltdown and businesses continues to fail or merge. The study used data from non-financial listed companies in Nigeria providing empirical supports that MO significantly associates with MMs in the right direction. Likewise, QDA also influences the MMs in the right direction suggesting that QDA is necessarily required to enhance adequate MMs. The findings of this study provide support for the association of MO and MMs with the intervention of QDA for solutions to agency problems. Companies should, therefore, motivate the management to own shares within the reasonable range that aligns the interest of the management with that of the shareholders. This paper adds to knowledge especially in Nigeria and Sub-Saharan Africa by examining a mediating effect to depict the relationship between MO and MM, which are not evident in prior studies
It is my conviction that in the coming year, the vision of IPJAF to publish high-quality manuscripts in the established and emergent areas of accounting and finance from academic and professional researchers will be sustained and appreciated.
As you read throughout this volume 2, issue 2 of IPJAF, I would like to remind you that the success of our journal depends on you, your friends and colleagues as stakeholder through the submission of high-quality articles for review and publication.
Once again, I acknowledge with gratitude your continued support as we strive to make IPJAF the most authoritative journal on accounting and finance for the community of academic, professional, industry, society and government.

Full textAbstract:
Ongoing reductions in the costs of solar PV and battery technologies have contributed to an increased use of home energy systems in Sub-Saharan African regions without grid access. However, such systems can normally support only low-power end uses, and there has been little research regarding the impact on households unable to transition to higher-wattage energy services in the continued absence of the grid. This paper examines the challenges facing rural energy transitions and whether households feel they are energy ‘locked in’. A mixed-methods approach using questionnaire-based household energy surveys of rural solar home system (SHS) users was used to collect qualitative and quantitative data. Thematic analysis and a mixture of descriptive and inferential statistical analyses were applied. The results showed that a significant number of households possessed appliances that could not be powered by their SHS and were willing to spend large sums to connect were a higher-capacity option available. This implied that a significant number of the households were locked into a low-energy future. Swarm electrification technology and energy efficient, DC-powered plug-and-play appliances were suggested as means to move the households to higher tiers of electricity access.

Full textAbstract:
The operation of hydrokinetic turbine depends on river flow and pressure head (∆H) which are of high potential in many parts of Nigeria. This study attempts the analysis of the potential of the area upstream of Ikere Gorge dam for hydrokinetic potential. Soil and Water Assessment Tool (SWAT) was used to determine the hydrological parameters of the sub-basins. Pearson Moment Correlation and linear regression methods were used to find the relationships between morphometric properties and the discharge parameters. Hydrological modeling and statistical computations were done to estimate the theoretical potential of the catchment. The result shows that River Oshe has 9.542 MW, which is the highest potential while River Konsun with 1.161 MW has the lowest potential Pearson Moment Correlation shows that there is strong positive relation of 0.7 between slope and pressure head (∆H) at 0.05 significant levels. The result of the multiple regression show that hydro-geomorphic factors explained 59.1% of the variance in the explanation of hydrokinetic power potential upstream of Ikere gorge dam.

Full textAbstract:
Lack of good-quality planting materials has been identified as the most severe problem militating against increased agricultural productivity in sub-Saharan Africa (SSA) and beyond. However, investment of research efforts and resources in addressing this menace will only be feasible and worthwhile if attendant economic gains are considerable. As a way of investigating the economic viability of yam investment, this research has been initiated to address problems confronting yam productivity in eight countries of SSA and beyond: Nigeria, Ghana, Benin, Togo, Côte d’Ivoire, Papua New Guinea, Jamaica, and Columbia. Research options developed were to be deployed and disseminated. Key technologies include the adaptive yam minisett technique (AYMT), varieties adapted to low soil fertility and drought, nematode-resistant cultivars (NRC), and crop management and postharvest practices (CMPP). This article aims at estimating the potential economic returns, the expected number of beneficiaries, and poverty reduction consequent to the adoption of technology options. Estimates show that the new land area that will be covered by the technologies in the eight countries will range between 770,000 ha and 1,000,000 ha with the highest quota accounted for by AYMT. The net present value will range between US$584 and US$1392 million and was highest for the NRC. The CMPP had the lowest benefit-cost ratio of 7.74. About 1,049,000 people would be moved out of poverty by these technologies by 2037 in the region. These technologies are less responsive to changes in cost than that in adoption rate. Therefore, the realization of the potential economic gains depends on the rate and extent of adoption of these technologies. Giving the knowledge-intensive nature of some of these interventions, capacity building of potential adopters will be critical to increasing the sustainability of the yam sector, thereby enhancing food security and reducing poverty.

Full textAbstract:
SummaryNational Parks have become the most widely-used category of protected areas in developing countries, including sub-Saharan Africa. Several studies have shown that local-community support for National Parks is based mainly on perceptions of benefits and costs against the background of social, cultural, political and economic considerations. This paper examines the experience in the Cross River National Park (CRNP) in southeast Nigeria using data collected through rapid rural appraisal techniques, household questionnaire surveys, focus group discussions and guided interviews. The results show that in spite of a high level of community awareness of the need to conserve the forests of the study area, there is a low level of local support for the CRNP forest conservation initiative. Four main factors are identified as the main influences on the support extended to the project, namely: reality and expectations of socio-economic development, the pace of project implementation, the relationship between park staff and communities, and the historical rights of local people to the forest of the study area. The implications of the findings relate to the long-term sustainability of the CRNP as a protected forest area.

Abstract This work presents a design for Hydrokinetic Renewable Energy (HRE), for off grid power generation for remote riverine regions in developing nations. The uniqueness of this technique for power generation using streams and other marine currents to generate electric energy is detailed. The problem of the impact of greenhouse gas emissions on the environment, rapid increase in human population, industries, modernization and our lifestyle put immense pressure on most power generation plants and infrastructures. Thus, global warming and carbon footprints of using fossil fuels to generate energy has driven the interest for energy generation from renewable sources. The Upper River Benue and Lower River Niger coastal basins, as well as the River Niger Basin on the Lower Niger sub-basin area of southeastern Nigeria was selected as a case study for the design of the hydrokinetic power generation technology. The results show that for a hydrokinetic turbine the level of power output is directly proportional to the flow velocity. Therefore the cost of its installation is reduced drastically from about $7,900 per installed kW to about $2,500 per kW, is easily assessable, less technical and a familiar motor technology for most of these communities. It is also a predictable form of energy in comparison to other emerging renewable energy fields like wind, solar and wave. Also this form of renewable energy is less harmful to the environment, has a lower noise emission and produces no greenhouse gases or any solid waste. HRE will bring energy security that is essential for the riverine dweller and curb rural urban migration and both improves the rural communities' standard of living and enhances their productivity.

IntroductionPalliative care is a clinically and cost‐effective component of cancer services in sub-Saharan Africa (SSA). Despite the significant need for palliative cancer care in SSA, coverage remains inadequate. The exploration of digital health approaches could support increases in the quality and reach of palliative cancer care services in SSA. However, there is currently a lack of any theoretical underpinning or data to understand stakeholder drivers for digital health components in this context. This project addresses this gap through engaging with key stakeholders to determine data and information needs that could be supported through digital health interventions.Methods and analysisThis is a multicountry, cross-sectional, qualitative study conducted in Nigeria, Uganda and Zimbabwe. In-depth interviews will be conducted in patients with advanced cancer (n=20), caregivers (n=15), health professionals (n=20) and policy-makers (n=10) in each of the three participating countries. Data from a total of 195 interviews will transcribed verbatim and translated into English before being imported into NVivo software for deductive framework analysis. The analysis will seek to understand the acceptability and define mechanisms of patient-level data capture and usage via digital technologies.Ethics and disseminationEthics approvals have been obtained from the Institutional Review Boards of University of Leeds (Ref: MREC 18–032), Research Council of Zimbabwe (Ref: 03507), Medical Research Council of Zimbabwe (Ref: MRCZ/A/2421), Uganda Cancer Institute (Ref: 19–2018), Uganda National Council of Science and Technology (Ref: HS325ES) and College of Medicine University of Lagos (Ref: HREC/15/04/2015). The project seeks to determine optimal mechanisms for the design and development of subsequent digital health interventions to support development, access to, and delivery of palliative cancer care in SSA. Dissemination of these findings will occur through newsletters and press releases, conference presentations, peer-reviewed journals and social media.Trial registration numberISRCTN15727711

Purpose The purpose of this paper is to consider recent field evidence to analyse what online public services citizens need, explores potential citizen subsidy of these specific services and investigates where resources should be invested in terms of media accessibility. The authors explore these from a citizen-centric affordability perspective within three exemplar developing countries in sub-Saharan Africa. The World Bank and United Nations in particular promote initiatives under the “Information and Communication Technologies for Development” (ICT4D) to stress the relevance of e-Government as a way to ensure development and reduce poverty. The authors adopt a contingency value approach to determine directly reported citizens willingness to pay for digital public services. Hence, our focus is mainly upon an empirical investigation through extensive fieldwork in the context of sub-Sahara Africa. A substantive survey was conducted in the respective cities of Addis Ababa (Ethiopia), Lagos (Nigeria) and Johannesburg (South Africa). The sample of citizens was drawn from each respective Chamber of Commerce database for Ethiopia and South Africa, and for Nigeria a purchased database of businesses, based on stratified random sampling. These were randomly identified from both sectors ensuring all locations were covered with a total sample size of 1,297 respondents. It was found, in particular, that citizens were willing to pay to be able to access digital public services and that amounts of fees they were willing to pay varied depending on what services they wish to access and what devices they use (PCs or mobile phones). Design/methodology/approach The authors adopt a contingency value approach to determine directly reported citizens willingness to pay for digital public services. A survey was conducted in the respective cities of Addis Ababa (Ethiopia), Lagos (Nigeria) and Johannesburg (South Africa). The sample of citizens was drawn from each respective Chamber of Commerce database for Ethiopia and South Africa, and for Nigeria a purchased database of businesses, based on stratified random sampling. These were randomly identified from both sectors ensuring all locations were covered with a total sample size of 1,297 respondents. Findings The findings suggest that by understanding citizen needs, demands and how they can benefit from online public services could drive decisions related to what public services need to be prioritised for economically active citizens, potentially explore citizen subsidy of these specific public services which will have a trickle-down benefit to poorer citizens by reducing the pressures on traditional channels of public service delivery and investigate where resources should be invested in terms of media to access online services. Willingness to pay between the top online public services showed no statistically significant difference among all respondents. Research limitations/implications The research focused on economically active digitally savvy citizens in the major capital cities in each of our selected countries. While these are not representative of the population at large, our intention was to understand what citizen-led government services would look like from the perspective of this group, with an insight into the value they place on these online services and their ability to access them. Technology diffusion starts with the early adopters (Rogers, 2010), and here the authors have focused on those that are likely to be early adopters. Practical implications Poor fiscal capacity, namely, the amount and type of resources a state has at its disposal, not only has an impact on economic wellbeing, but particularly relevant in this case, also has an impact on the quality of government (Baskaran and Bigsten, 2013). Thus, e-government is one way in which developing countries can focus on developing good governance and strengthening civil society to improve the quality of government and motivate citizens to participate in the political process. Social implications The economic performance of African countries has been viewed with pessimism, consistently considered to be the poorest continent (Harrison et al., 2014). Recent studies have empirically shown that new information technologies have contributed to longer term economic growth in African countries and stress the need for government to further invest in developing telecommunications infrastructures and internet access (Donou-Adonsou et al., 2016). However one of the major constraints and challenges for developing countries is the limited fiscal capacity and ability to mobilise fiscal resources to finance the provision of public services, which is essential for economic development (Ali et al., 2015). Originality/value The authors contribute to the World Bank and United Nations initiatives to promote ICT for Development’ (ICT4D) the relevance of e-government as a way to ensure development and reduce poverty. If online services are of no benefit, even if they are more convenient and lower cost, they are unlikely to be used. Accessing digital public services directly addresses the needs of economically active citizens and can also facilitate the steps towards an improved quality of government and interaction with civil society. The study has contributed to an insightful understanding of the value, cost and benefits of citizen-led e-Government in this respect.

Full textAbstract:
The main purpose of this study was to determined competency training needs of polytechnic Pre-service technicians for diagnosis and repairs of modern automobiles in North-Eastern Nigeria. The study sought to answer two research questions using CompetencyOutcomePerformanceAssessment (COPA) model framework. It is paramount importance to note that competency training needs of diagnosis and repairs of modern cars requires practical and effective training skills to be able to adequately repair them. A descriptive survey research design was adopted for the study. The population for the study was made up of 384 technicians in automotive technology in the NBTE accredited polytechnics in Northern Nigeria. Out of 384 a sample of 192 was randomly selected for the study. The questionnaire consisted of 192 tasks on diagnosis and repairs skills needed, developed with reference to curriculum of National Automobile Technician Education (NATE) and National Vocational Certificate in Automotive / Mechatronics approved by National Board for Technical Education. The questionnaire was divided into two sections: A & B, (see Appendix I). Section A contains items designed to obtain personal information of the respondents, while section B is divided into four sub-sections (I, II, III & IV). The instrument was developed using COPA Model structure, adapted from Lenburge et al (2009). A four-point rating scale ranges from Highly Needed (HN) = 4, Needed (N) = 3, Moderately Needed (MN) = 2, Least Needed (LN) = 1 was employed in sub-section I, while four-point rating scaled ranges from most relevant (4), highly relevant (3), moderately relevant (2) and less relevant. A reliability test of the instrument was also conducted and analyzed using Cronbach Alpha coefficient method and yielded an overall reliability coefficient of 0.80. Data generated from the use of the questionnaire was analyzed with Statistical Package for Social Sciences (SPSS) 23rd version software using mean and standard deviation to answer the research questions. Findings revealed relevant interactive strategies needed in the training of polytechnic Pre-service Technicians in diagnosis and repairs of modern Automobiles. Based on the findings of the study, appropriate recommendations were made, among which is, that the identified modern technology skills should be integrated into the curriculum of Automotive Technology programme in Nigerian polytechnic. Identified interactive skills will help lecturers in developing lesson plan using the competencies that are essentially needed by Pre-service automotive technicians in order for them to prepare on how to teach them appropriately.

The EDCTP community meets biennially to share research findings, plan new partnerships and collaborations, and discuss maximising impact from EDCTP-funded research. In 2018, the Ninth EDCTP Forum took place in Lisbon, Portugal, from 17–21 September 2018. The Lisbon meeting was the largest international conference focusing on clinical research on poverty-related infectious diseases in sub-Saharan Africa. It started with a strong commitment, from European and African EDCTP member countries, for a successor programme to EDCTP2 (2014–2024). It provided a platform for the presentation of project results and discussion of progress in clinical research and capacity strengthening in sub-Saharan Africa.The theme of the Ninth Forum was ‘Clinical research and sustainable development in sub-Saharan Africa: the impact of North-South partnerships’. This reflected not only the broader scope of a larger EDCTP research programme but also the growing awareness of the need for global cooperation to prepare for public health emergencies and strengthen health systems. The theme highlighted the impact of Europe-Africa partnerships supporting clinical research and the clinical research environment, towards achieving the sustainable development goals in sub-Saharan Africa.A central topic of the Forum was the discussion of the character and scope of an EDCTP successor programme, which should start in 2021 under the next European Framework Programme for Research and Innovation, Horizon Europe. On 17 September, a high-level meeting on this topic took place immediately before the opening of the Forum1. On 19 September, the plenary session continued this discussion through a panel of representatives of strategic partners. There was consensus on the added value of the programme for Europe and the countries in sub-Saharan Africa and political commitment to a successor programme. Poverty-related infectious diseases and a partnership approach will remain central to the programme. There was also a general awareness that all participating countries would need to engage more strongly with a successor programme, both in its governance and in their financial contributions to its objectives.The Forum hosted 550 participants from more than 50countries. The programme consisted of keynote addresses by policy makers, research leaders, and prominent speakers from Europe and Africa in 5 plenary presentations. There were 9 symposia, 45 oral presentations in parallel sessions, and 74 electronic poster presentations. Abstracts of the plenary, oral and poster presentations are published in this supplement to BMJ Global Health.EDCTP is proud of its contribution to strengthening clinical research capacity in Africa, with more than 400 postgraduate students and 56 EDCTP fellows supported under the first EDCTP programme. The second programme developed a comprehensive fellowship scheme. More than 100 EDCTP fellows (former and current) participated in a one-day pre-conference to discuss the further development of our Alumni Network launched in 2017. The Forum also offered scholarships to many early and mid-career researchers from sub-Saharan Africa and Europe. With the support of the European Union, EDCTP member countries and sponsors, they were able to present results of their studies and meet colleagues from Africa and Europe.The Forum also provided the appropriate platform for recognising individual and team achievements through the four EDCTP 2018 Prizes. With the support of the European Union, EDCTP recognised outstanding individuals and research teams from Africa and Europe. In addition to their scientific excellence, the awardees made major contributions to the EDCTP objectives of clinical research capacity development in Africa and establishing research networks between North and South as well as within sub-Saharan Africa.Dr Pascoal Mocumbi Prize Professor Souleyman Mboup (Professor of Microbiology, University of Cheikh Anta Diop, Dakar; Head of the Bacteriology-Virology Laboratory of CHU Le Dantec, Dakar; and President of IRESSEF, Senegal) was recognised for his outstanding achievements in advancing health research and capacity development in Africa.Outstanding Research Team Prize The prize was awarded to the team of the CHAPAS (Children with HIV in Africa – Pharmacokinetics and acceptability of simple antiretroviral regimens) studies, led by Professor Diana Gibb (MRC Clinical Trials Unit, United Kingdom).Outstanding Female Scientist Prize The prize was awarded to Professor Gita Ramjee (Chief Specialist Scientist and Director of the HIV Prevention Research Unit of the South African Medical Research Council, Durban, South Africa) for her outstanding contributions to her field.Scientific Leadership Prize The prize was awarded to Professor Keertan Dheda (Head of the Centre for Lung Infection and Immunity and Head of the Division of Pulmonology at Groote Schuur Hospital and the University of Cape Town, South Africa) for his research contributions and leadership.Partnership is at the core of the EDCTP mission. In the year before the Forum, Nigeria and Ethiopia were welcomed as the newest member countries of the EDCTP Association, while Angola became an aspirant member. Partnership was also demonstrated by the many stakeholders who enriched the programme by organising scientific symposia, collaborative sessions and workshops. We thank our sponsors Novartis, Merck, the European Union, the Federal Ministry of Education and Research (Germany), the Institute of Health Carlos III (Spain), the National Alliance for Life Sciences and Health (France), the Medical Research Council (United Kingdom), the Swedish International Development Agency (Sweden), ClinaPharm (African CRO), the Deutsche Stiftung Weltbevölkerung (Germany), The Global Health Network (United Kingdom), PATH, and ScreenTB. We gratefully acknowledge the support of our partners and hosts of the Forum, the Portuguese Foundation for Science and Technology and the Calouste Gulbenkian Foundation.The tenth EDCTP Forum will take place in sub-Saharan Africa in 2020.

Full textAbstract:
Purpose The technology determinism theory facilitated in assessing the impact of interactive radio and social network sites (SNSs) on development factors such as education, agriculture, health, and governance, by conducting an integrative and comprehensive literature review focusing on African countries. This paper aims to conduct this literature review to provide comprehensive empirical evidence on the impact of interactive radio and SNSs on development in Africa. Design/methodology/approach This study examined articles that were retrieved from online databases including EBSCOhost, Elsevier, Science Direct, SAGE Journals, Springer and Wiley Online Library. The keywords used included interactive radio, radio, development in Africa, SNS, agriculture, education, health, peace and governance. Search phrases were formulated using boolean operators “AND” and “OR.” Findings Study results revealed that interactive radio and SNSs improve knowledge among farmers and allow the dissemination of information on innovative agricultural techniques, which supports the adoption of sustainable practices. Interactive radio promotes political accountability because the strategies provide the voiceless and powerless communities with a platform to express themselves. This paper discovers that the incorporation of SNS with existing multimedia communication facilitates the dissemination of health-related information on illnesses such as Ebola, HIV, hypertension, diabetes and Polio, and interactive radio and SNS promote education among marginalized communities and under-served rural schools. Research limitations/implications The findings on the impact of interactive radio and SNSs do not represent all 54 countries in Africa. Although the studies included in this literature review were conducted in several countries such as South Africa, Nigeria, Somalia, Kenya, Malawi, Ghana, Tanzania, Uganda and Zambia, this limited the generalizability of the findings and recommendations. Also, the other potential limitation is that using the inclusion-exclusion criteria could have resulted in bias when selecting the studies to include in the review. Practical implications The paper might serve as a valuable source of information for students, academics and entrepreneurs where the impact of interactive radio and SNSs on agriculture, education, health and governance, which are core determinants of development in Africa, has been assessed for further case studies in this area. Social implications The use of interactive radio has helped in decreasing health issues caused by a deficiency in vitamin A among children in sub-Saharan Africa. Originality/value The development of sustainable and effective interactive radio programs is dependent on the collaboration of the core stakeholders such as governmental ministries, donor organizations and the mass communication sector. Numerous open sources on technology radio stations are available to employ social media managers to help in the application of knowledge.

Full textAbstract:
<p>This paper tries to put forward an anthropo-linguistic approach to the promotion of Nigerian dress culture in corporate institutions. Linguistic anthropology is a twin discipline which is concerned with the study of human society. It examines culture in its totality – traditions, customs, languages, dress, artifacts and technology, together with human social behaviour and relationships. Dress culture belongs to the sub-division of anthropology called ethnology, which looks at cultures in their traditional forms, and in their adaptation to the changing conditions in the modern world. Dress culture is therefore seen in this paper as a system of communication that functions just like any language functions. For instance, the related subject of Semiotics – the science of signs and significations, i.e. the study of symbols and their communicative meanings – has made dress culture an interesting and intriguing mode of communication. Dress is symbolic, iconic and symptomatic, and it is open to diverse interpretations and meanings. Dress code in corporate institutions just like any symbolic language, speaks volume. The authors therefore explore dress culture in its ramification – ethnic / national ceremonial dress, occasional/ festival dress, corporate/professional dress, religious / ritual dress, political dress, etc., the interpretations of colours, and the role of dress culture in the promotion of national identity. It is suggested that Nigerian dress culture must be sensitive to people’s taste, convenience, style, sex, religious belief, and must consider climatic or weather conditions and modernity if it is to serve as a veritable communication tool.</p>

Full textAbstract:
Smart meter technology installation as a potent means of energy management is a nascent and evolving phenomenon in most developing countries in Sub-Saharan Africa. The ascendency is exponentially provoking migration from hugely unmetered electricity consumers in favour of smart meter technology. For policymakers to formulate actionable and effective energy policies, a deeper understanding of factors that culture users’ interest in smart meter technology is necessary. Despite the imperativeness of consumers’ viewpoints in policy-design, little contemporary insights still exit regarding those antecedents that propel electricity consumers to switch to smart meter. Accordingly, this study examines determinants of smart meter and their potential influence on sustainable energy consumption behavior among residents in under-reported sub-urban areas in Nigeria. The drivers were employed to extend the Theory of Planned Behavior. One hundred and fifty copies of self-administered questionnaire serve as data collection instrument from participants. Structural equation modeling technique with the assistance of SmartPLS software was utilized in data analysis relating to the hypothesized paths in the research framework. Findings show that bill estimation anxiety and perceived behavioral control were the critical factors that determine smart meter purchase intentions and indirectly influence sustainable energy consumption behavior. Other lesser yet significant constructs were environmental concern, attitude, and subjective norm. Theoretical and potential energy policy/marketing implications of the findings were highlighted.

Background: Haematological changes have been associated with physical activity (exercise) and these changes have been found to involve leucocytes, red blood cells and thrombocytes depending on variables such as the duration and intensity of the exercise. Objective: This experimental pre-post test study was designed to assess the changes in white blood cell, red blood cell and platelet parameters following short term exercise. Method: A total of 30 participants with an average age of 23.8 ± 1.98 years participated in the standard treadmill exercise (Bruce protocol) for 30 minutes on voluntary basis. Blood samples were collected from the subjects before exercise, immediately after exercise and 24 hours after exercise. Hematological parameters were analyzed using hematology auto-analyzer. Height, weight, body mass index and blood pressure of the participant were measured. Ethical approval was obtained from the Ethics committee of Faculty of Health Sciences and Technology and informed consent of the participants were obtained. Statistical Package for Social Sciences version 21 was used for statistical analysis. Results: The platelet count significantly increased post-exercise compared to pre-exercise and decreased 24hours post-exercise compared to postexercise value. Conversely, the Platelet distribution width (PDW) significantly decreased at post-exercise compared to pre-exercise, and significantly increased at 24hours post exercise compared to post-exercise value. Moreover, there was a significant increase in Mean platelet volume (MPV) at 24hours post-exercise compared to post exercise and a significant decrease in Plateletcrit (PCT) at 24hours post-exercise compared to post-exercise. At post-exercise and 24hours post-exercise, the total lymphocyte count was significantly higher in females while the granulocyte count was significantly higher in males. Also at 24 hours post exercise the MCHC was significantly higher in females compared to males. At post-exercise, there was a significant positive correlation between BMI and MCH (r=0.512, P=0.004) and BMI and MCHC (r=0.553, P=0.003) while there was a significant negative correlation between BMI and MPV (r=-0.367, P=0.046). Conclusion: Short term exercise causes significant alterations in platelet parameters than other hematological parameters.

GSC Biological and Pharmaceutical Sciences 14, no. 3 (March 30, 2021): 122–28. http://dx.doi.org/10.30574/gscbps.2021.14.3.0042.
Full textAbstract:
The antimicrobial susceptibility of Helicobacter pylori isolated from suspected patient using stool sample at Beijing greatest college of health sciences and technology, Kaduna, demonstration clinic. The analyses were carried out to further understand the intestinal environment condition of the sample sites. As it has been noted that: it is difficult of growing Helicobacter pylori in a broth, hence, no specific enrichment has been proposed. Note: As everything present in the stomach would be found in the stools, hence there is no doubt that Helicobacter pylori can be eliminated via this route and successful culturing of Helicobacter pylori from the stool sample had been achieved. [4]. The stool was diluted to a 20% w/v solution of in phosphate buffered saline (PBS) and the suspension was sieved through a 250 um strainer before plating onto the selective media. The sample was passed through a series of dilution techniques and centrifugation before finally plating on to the deoxycholate citrate agar (selective) and incubates at 37oC under the microacrobic atmospheric oxygen concentration of 7 – 12% (O2) for four (4) days. Across the cultured, the cultured plate there was marked abundant of bacterial cells with some colonies having the characteristics of Helicobacter pylori which later sub-cultured and isolated for antimicrobial test.

Full textAbstract:
Purpose It is generally agreed that shortage of food, which is one of the main problems bedevilling Sub-Saharan African region, can be eliminated via the adoption of modern agricultural production technology, one of which is chemical fertiliser. The purpose of this paper is to assess the factors that can be used to improve the intensity of fertiliser use in rural Sub-Saharan African countries, taking Tofa, a local government area in Kano State, Nigeria, as the case study. Design/methodology/approach The study adopted a two-stage sampling technique. In the first stage, four districts were chosen using a simple random sampling technique from the list of the 15 districts in the local government area, namely, Tofa, Langel, Lambu and Doka. In the second stage, 25 farmer households were systematically selected from each of the selected communities. Moreover, Tobit Regression model was used to examine and analyse the influence of some socio-economic factors on fertiliser use intensity. Findings To improve the rate of fertiliser use intensity, farmers need to be exposed to skills and training on some off-farm jobs to raise the farmers’ income to enable them to afford more fertiliser. The study finds that income, contact with extension agent, age of the farmer and method of fertiliser application have positive significant impacts on the intensity of fertiliser use. On the other hand, price of fertiliser was found to have negative impact on the intensity of using fertiliser in the study area. Furthermore, based on the data obtained from the selected samples, the average rate of fertiliser application in Tofa local government area during the crop season of 2011/2012 was 25 kg per hectare. Originality/value Policies that will strengthen the farmers’ contact with extension agents throughout the farming periods should be adopted. Also, farmers need to be exposed with skills and training on some off farm jobs to raise the farmers’ income to enable them afford more fertiliser.

Full textAbstract:
The Water Exploitation Index (WEI), or withdrawal ratio, is an indicator of water scarcity, which has been updated into its WEI+ form by the Committee of Experts of the European Commission. In calculating the total abstraction of fresh water, this indicator also includes the possible return flow and management rules. The demand for freshwater and long-term freshwater resources are both necessary to calculate the WEI+. These values are not easy to assess at basin or sub-basin level and, for this reason, WEI values are generally calculated at the country level. This paper introduces a new approach to calculate the WEI+, with the purpose of extending its use to basin and sub-basin levels. The methodology is based on flow duration curve estimation, which evaluates freshwater resources, and a Web-GIS system that evaluates water abstractions distribution. This approach allows for the assessment of locally stressed areas in the hydrographic network and could provide a fundamental step toward more comprehensive regional water resources management plans. The new methodology is tested in some sub-basins of the Upper Tiber River Basin (Italy). These results contribute to the analysis of water withdrawals sustainability, based on the policy of the European Environment Agency, which is aimed toward the development of a proactive approach for reducing water stress.

Full textAbstract:
During the last few decades there has been a sharp transition in economic doctrine, within the context of economic growth, on the relative contributions of agriculture and industrial development. There has been a shift away from the earlier 'industrial fundamentalism' to an emphasis on the significance of growth in agricultural productivity and production. The focus, especially in the context of the present-day less developed countries like Pakistan, has sharpened with the rapid growth in demand for food, resulting from the increasing growth in population and the high income-elasticities of the demand for food. Coupled with this is the transition from resource-based agriculture to science-based agriculture. Agricultural economists are unanimous in the view that by the end of this century all increases in world food production will come from higher yields, i.e. increased output per hectare. This increasing emphasis on 'land-saving' technology to increase productivity and production has resuited from the growing population pressures on land and declining land-man ratios. Agricultural research has come to the fore in providing technologies that increase productivity and production. However, these technologies do not explicitly take into account the equity aspects of the problem. The extent to which the poor gain or lose from the introduction of a new agricultural technology depends on a host of complex and interrelated socio-economic and political factors such as the existing distribution of productive resources, access to modem inputs, the structure of the market, etc.

ABSTRACTThe fungusAspergillus nigerforms (sub)millimeter microcolonies within a liquid shaken culture. Here, we show that such microcolonies are heterogeneous with respect to size and gene expression. Microcolonies of strains expressing green fluorescent protein (GFP) from the promoter of the glucoamlyase geneglaAor the ferulic acid esterase genefaeAwere sorted on the basis of diameter and fluorescence using the Complex Object Parametric Analyzer and Sorter (COPAS) technology. Statistical analysis revealed that the liquid shaken culture consisted of two populations of microcolonies that differ by 90 μm in diameter. The population of small microcolonies of strains expressing GFP from theglaAorfaeApromoter comprised 39% and 25% of the culture, respectively. Two populations of microcolonies could also be distinguished when the expression of GFP in these strains was analyzed. The population expressing a low level of GFP consisted of 68% and 44% of the culture, respectively. We also show that mRNA accumulation is heterogeneous within microcolonies ofA. niger. Central and peripheral parts of the mycelium were isolated with laser microdissection and pressure catapulting (LMPC), and RNA from these samples was used for quantitative PCR analysis. This analysis showed that the RNA content per hypha was about 45 times higher at the periphery than in the center of the microcolony. Our data imply that the protein production ofA. nigercan be improved in industrial fermentations by reducing the heterogeneity within the culture.

This study aim to attempt mapping out the Land Use or Land Cover (LULC) status of Regional Project Coordination Committee (RPCC) between 2009-2019 with a view of detecting the land consumption rate and the changes that has taken place using RS and GIS techniques; serving as a precursor to the further study on urban induced variations or change in weather pattern of the cityn Rangpur City Corporation(RCC) is the main administrative functional area for both of Rangpur City and Rangpur division and experiencing a rapid changes in the field of urban sprawl, cultural and physical landscape,city growth. These agents of Land use or Land cover (LULC) varieties are responsible for multi-dimensional problems such as traffic congestion, waterlogging, and solid waste disposal, loss of agricultural land. In this regard, this study fulfills LULC changes by using Geographical Information Systems (GIS) and Remote Sensing (RS) as well as field survey was conducted for the measurement of change detection. The sources of data were Landsat 7 ETM and landsat 8 OLI/TIRS of both C1 level 1. Then after correcting the data, geometrically and radiometrically change detection and combined classification (supervised & unsupervised) were used. The study finds LULC changes built-up area, water source, agricultural land, bare soil in a change of percentage is 17.23, 2.58, -9.94, -10.19 respectively between 2009 and 2019. Among these changes, bare soil is changed to a great extent, which indicates the expansion of urban areas is utilizing the land to a proper extent.

AbstractIn June 2001, the CORESTA2 Board formally decided to broaden the scope of CORESTA by engaging in biosciences (other than tobacco agronomy and phytopathology), starting with in vitro toxicity testing and biomarkers of tobacco (smoke) exposure. Until then, work addressing biological aspects of smoking had only been done since 1996 by a special committee within CORESTA, reporting directly to the Scientific Commission, the Smoking Behaviour Committee. Membership of that committee was - similar to ACAC3 - by invitation only. The broadened scope consequently led to the re-shaping of the then Study Groups ‘Smoke’ and ‘Technology’ into ‘Smoke Science’ (SS) and ‘Product Technology’ (PT).Subsequently, three Sub-Groups (SG) and Task Forces (TF) were set up, reflecting this change: i) SG Smoking Behaviour (name change of former Committee in 2001), ii) TF ‘Nicotine Intake’ (2001, later on named ‘Nicotine Uptake’, disbanded in 2009) and iii) TF ‘In vitro Toxicity Testing of Tobacco Smoke’ (2002). Finally, a new SG ‘Biomarkers’ was launched in 2009 with a wider scope than its predecessor TF ‘Nicotine Uptake’. The work of these groups has had and still has significant impact on the scientific work within CORESTA, leading to numerous presentations at CORESTA meetings and publications in peer-reviewed journals.This paper provides a brief analysis of some 270 presentations and posters addressing tobacco smoke toxicity, human smoking behaviour or biomarkers, delivered at CORESTA Congresses and SSPT Joint Meetings between 1993 and 2011. More than 50% of these papers covered different aspects of toxicology, mainly in vitro toxicity testing methodologies, smoke exposure systems and other equipments. Other papers described the influence of cigarette design parameters on smoke toxicity. Approaches to human risk assessment were presented, including the search for suitable in vitro models of the major smoking related human diseases.CORESTA began discussing smoking behaviour topics at their Vienna meeting in 1995 and received five respective presentations there; indeed, the issue has various aspects, from smoking topography and human smoke yield to smoke uptake, deposition and retention, and… Why do people smoke at all?As early as 1996, a presentation was given on the determination of urinary mutagenicity in volunteers exposed to ETS (environmental tobacco smoke), apparently indicating a need for CORESTA to engage in this field and to face new challenges. Indeed, our knowledge of biomarkers and how to measure them has increased considerably over the years, and there is a clear trend towards using this knowledge for conducting clinical studies into the assessment of ‘modified risk tobacco products’.

Full textAbstract:
IntroductionAntimicrobial resistance (AMR) is a growing problem globally especially in Sub-Saharan Africa including Kenya. Without any intervention, lower/middle-income countries (LMICs) will be most affected due to already higher AMR levels compared with higher income countries and due to the far higher burden of diseases in the LMICs. Studies have consistently shown that inappropriate use of antimicrobials is the major driver of AMR. To address this challenge, hospitals are now implementing antibiotic stewardship programmes (ASPs), which have been shown to achieve reduced antibiotic usage, to decrease the prevalence of resistance and lead to significant economic benefits. However, the implementation of the guideline is highly dependent on the settings in which they are rolled out. This study, employing an implementation science approach, aims to address the knowledge gap in this area and provide critical data as well as practical experiences when using antibiotic guidelines and stewardship programmes in the public health sector. This will provide evidence of ASP performance and potentially contribute to the county, national and regional policies on antibiotics use.Methods and analysisThe study will be conducted in three geographically diverse regions, each represented by two hospitals. A baseline study on antibiotic usage, resistance and de-escalation, duration of hospital stay, rates of readmission and costs will be carried out in the preimplementation phase. The intervention, that is, the use of antibiotic guidelines and ASPs will be instituted for 18 months using a stepwise implementation strategy that will facilitate learning and continuous improvement of stewardship activities and updating of guidelines to reflect the evolving antibiotic needs.Ethics and disseminationApprovals to carry out the study have been obtained from the National Commission for Science, Technology and Innovation and the Mount Kenya University Ethics Review Committee. The approvals from the two institutions were used to obtain permission to conduct the study at each of the participating hospitals. Study findings will be presented to policy stakeholders and published in peer-reviewed scientific journals. It is anticipated that the findings will inform the appropriate antibiotic use guidelines within our local context.

I welcome you to the Vol. 1 Issue 2 of Indian-Pacific Journal of Accounting and Finance. You will recall in Issue 1, I made known our commitment to publish high-quality, impactful papers and to bring scholars who share our vision and mission into the Editorial Advisory Board. Dr Ishaya John Dabari (Modibbo Adamawa University of Technology, Adamawa, Nigeria) has consented to join the Editorial Advisory Board. I am pleased to welcome him on board.
In Issue 2, all the presentations are international research with emphasis on corporate governance and risk management, internal auditing, accounting information system, education, telecommunications, and banking sectors.
In the first paper captioned “Effect of Risk Management Committee on Monitoring Mechanismsâ€, Dr Rachael Oluyemisi Arowolo (Chrisland University), Prof Dr Ayoib B. Che-Ahmad (Universiti Utara Malaysia), and Asst. Prof. Dr Oluwatoyin Muse Johnson Popoola (Universiti Utara Malaysia) examines the influence of risk management committee (RMC) on monitoring mechanisms (MM) in Sub-Saharan Africa. The paper provides empirical supports for RMC association with monitoring mechanisms to reduce agency problems, using the secondary data (2010-2012) of Nigerian non-financial listed companies. The article recommends to the board of Nigerian companies to explore the usefulness of RMC in monitoring the management and controlling shareholders to lessen agency problems and protect the interests of the minority shareholders.
In the second paper entitled “Aligning Corporate Governance with Enterprise Risk Management Adoption in the Nigerian Deposit Money Banksâ€, Dr Ishaya John Dabari (Modibbo Adama University of Technology), Sini Fave Kwaji (Modibbo Adama University of Technology), and Ghazali Zulkurnai (Universiti Utara Malaysia) align corporate governance (CG) with Enterprise Risk Management (ERM) adoption in the Nigerian Deposit Money banks (DMBs). Their study used cross-sectional research design, survey method and questionnaire technique to collect data in 21 Nigerian DMBs. Out of 722 questionnaires distributed, 435 were found usable for further analysis through Structural Equation Modeling in Stata. The paper empirically reveals the significant positive relationship between CG and ERM adoption regarding internal audit effectiveness, human resource competency and top management commitment. The study provides insightful results for the banking industry, regulators, practitioners, academia and other stakeholders, perhaps to render assistance in the areas of policy formulation, implementation and evaluation.
In the third paper titled “Independence and Management Support: The advocate for Internal Auditors’ Task Performance in Tertiary Institutionsâ€, Oyewumi Hassan Kehinde (Universiti Utara Malaysia), Prof Dr Ayoib B. Che-Ahmad (Universiti Utara Malaysia), and Asst. Prof. Dr Oluwatoyin Muse Johnson Popoola (Universiti Utara Malaysia) examine the influence of independence (IND) and management support (MS) on the task performance (TP) of internal auditors in the South-West tertiary institutions in Nigeria. The study formulates and tests two hypotheses on the relationship between IND and TP in one hand, and MS and TP on the other hand. This study employs a quantitative approach, cross-sectional design, and survey questionnaire in obtaining data from 350 internal auditors from the internal audit departments/units of the universities, polytechnics, and colleges of education. The results of the PLS-SEM algorithm and bootstrapping reveal positive significant relationships between IND and TP, and the MS and TP, and hence, support the two hypotheses. The paper has a policy implication on the government/private proprietors who are owners of tertiary institutions; management and Council who control the institutions, internal auditors who are operators of internal auditing; regulatory authorities who perform oversight function on the institutions, and professional accounting and auditing bodies. The article adds to the body of knowledge and extends internal audit research to tertiary institutions.
In the fourth paper entitled “Examining Information Disclosure on Regulatory Compliance of Telecommunication Companies in Nigeriaâ€, Sini Fave Kwaji (Modibbo Adama University of Technology), Dr Ishaya John Dabari (Modibbo Adama University of Technology) examine the impact of information disclosure on regulatory compliance of telecommunication companies in Nigeria. The study adopted ex-post facto research design, which relies on secondary data collected from the financial statements of three (3) telecommunication companies out of the eight (8) telecommunication companies for the period of 2004 to 2015 and analysed through the multiple regression statistics. The results reveal that computed compliance index of telecommunication companies was above average (av. 75.6%) with the requirements of regulatory agencies. Also, the findings indicate that mandatory information disclosure (MID) recorded a significant impact at 10% (weak compliance), while voluntary information disclosure (VID) showed an effect at 5% (partial compliance). The article makes a clarion call for the enforcement of full compliance by all the telecommunication companies operating in Nigeria and therefore, recommends to the National Communication Commission (NCC) to monitor the compliance with the requirements of information disclosure and pursue its objective to achieve best corporate governance practices in Nigerian telecommunication companies.
In the fifth paper titled “Examining CAATTs implementation by internal auditors in the public sector.†Dr Aidi Ahmi (Universiti Utara Malaysia), Associate Prof Dr Siti Zabedah Saidin (Universiti Utara Malaysia), and Dr Akilah Abdullah (Universiti Utara Malaysia) investigate the implementation of CAATTs by internal auditors in the Malaysian public sector. Their research reports the results from 12 interviews conducted with internal audit departments in both federal and state levels. The study revealed the implementation of CAATTs by internal auditors in public sector is still low because of lack of expertise, high implementation and maintenance cost, limited access of auditee’s data, and preference to conduct the audit manually. Furthermore, it is not mandatory for them to use CAATTs. The evidence is a contrast with the encouragement made by the government to improve the IT usage in public sector. The results implied that training for future auditors in CAATTs to ensure the successful implementation is crucial and strategic. For CAATTs to be a success, the head of internal audit must possess the awareness about the importance of CAATTs as well as enforcement of its implementation.
As you read through this Vol. 1 Issue 2 of IPJAF, I would like to recap that the success of the journal depends on your active participation and those of your colleagues and friends through submission of high-quality articles for review and publication.
I reiterate to our prospective authors to enjoy the benefits IPJAF provides about mentoring nature of the unique review process, which offers high quality, and helpful reviews tailored to assist authors in improving their manuscripts.

IntroductionThe burden of post-tuberculosis (TB) lung disease (PTBLD) is steadily increasing in sub-Saharan Africa, causing disability among TB survivors. Without effective medicines, the mainstay of PTBLD treatment evolves around disease prevention and supportive treatment. Pulmonary rehabilitation (PR), a low-cost, non-pharmacological intervention has shown effectiveness in a group of PTBLD individuals but has not been tested in a clinical trial. This study aims to assess the impact of a 6-week PR programme on maximal exercise capacity and other outcomes among adults in Uganda living with PTBLD.Methods and analysisThis is a randomised waiting-list controlled trial with blinded outcome measures, comparing PR versus usual care for patients with PTBLD. A total of 114 participants will be randomised (1:1) to receive either usual care (on the waiting list) or PR, with follow-up assessments at 6 weeks and 12 weeks postintervention. The primary outcome is change in walking distance measured by the Incremental Shuttle Walk Test from baseline to the end of 6 weeks of PR. All secondary outcomes will be compared between the PR and usual care arms from baseline to 6-week and 12-week follow-ups. Secondary outcomes include self-reported respiratory symptoms, physical activity, psychological well-being, health-related quality of life and cost–benefit analysis. All randomised participants will be included in the intention-to-treat analysis population. The primary efficacy analysis will be based on both per-protocol and modified intention-to-treat populations.Ethics and disseminationThe trial has received ethical clearance from the Mulago Hospital Research and Ethics Committee (MHREC 1478), Kampala, Uganda as well as the Uganda National Council for Science and Technology (SS 5105). Ethical approval has been obtained from the University of Leicester, UK research ethics committee (Ref No. 22349). Study findings will be published in appropriate peer-reviewed journals and disseminated at appropriate local, regional and international scientific meetings and conferences.Trial registration numberISRCTN18256843.Protocol versionVersion 1.0 July 2019.

Abstract Abstract 2454 Mixed Lineage Leukemia (MLL) gene rearrangements are common genetic translocations occurring in human leukemia. Numerous MLL-partner genes have been identified so far; of these MLL-AF4 was found to characterize the largest subgroup of fusion proteins in pediatric acute lymphoblastic leukemia (ALL). A recent study reported that mutations in kras accelerate leukemo-lymphogenesis in a MLL-AF4 transgenic mouse model. Activating mutations in RAS genes, frequently occuring in codons 12, 13 and 61, prevent the hydrolysis of RAS-GTP and result in the constitutive activation of the RAS proteins enhancing cell survival and proliferation. Mutations in RAS genes were found in several types of human cancers, including leukemia and ALL with MLL rearrangements. We analyzed the presence of KRAS mutations in pediatric MLL-AF4 rearranged ALL samples at diagnosis and relapse with the aim to establish the frequency of KRAS mutations in MLL-AF4 leukemia and to tentatively associate RAS mutations to the leukemogenic process. In this study 40 ALL patients were included (23 infant and 17 non infant); of these, 14 pairs at diagnosis and relapse, 22 at diagnosis only and 4 samples at relapse only. The study was approved by the institutional ethical committee and informed consent was obtained in accordance with the Declaration of Helsinki. Mutation screening was performed for exon 2 and exon 3 of KRAS by 454 technology (Roche Applied Science) with GS Junior Sequencing Instruments; to recognize each specific patient, primer pairs included a 10-base molecular identifier barcode sequence (MID). We generated amplicon ultra-deep sequencing of the 2 amplicons with a median coverage per amplicon of 1800 reads per sample. Twenty patients (55,6%) out of 36 with t(4;11) at diagnosis harbored KRAS mutations (range of penetrance of 0,4–29,7% for mutated sequences). Interestingly, in some patients more than one clone with different mutations at difference penetrance in KRAS codons were present. Of the 18 relapse samples 4 (22%) harbor KRAS mutations (penetrance of 1.3–38% of reads). Sanger sequencing was used to validate the presence of mutations in patients with more of 20% of penetrance identified with 454 technology. To evaluate the role of KRAS mutations in the leukemogenic process we analyzed matched paired diagnostic and relapse samples; in patients with mutations at diagnosis, 3 distinct situations were identified in the relapsed samples, pointing different changes between diagnosis and relapse: (1) presence of KRAS mutations in a specific codon at diagnosis and disappearance of this clone at relapse (6 of 9 cases, 67%); (2) decrease of the penetrance of a mutation between diagnosis and relapse and appearance of a new different mutation at relapse (2 of 9 cases, 22%); (3) clonal evolution of the same mutation and increase of the percentage of the mutated sequence from diagnosis to relapse (1 of 9 cases, 11%). Apparently, patients with MLL-AF4 rearrangements at diagnosis and relapse presented with subclones and during the relapse phase previous clones disappeared while new clones appeared and only in one case we can assume a selective advantage of the clone with the KRAS mutation. To further explore the propagation of KRAS mutated subclones in MLL-AF4, we transplanted 2 patients at diagnosis into a NOD/SCID xenograft mouse model. Xenografted samples obtained from leukemia bearing mice transplanted further onto subsequent recipients in serial passages. KRAS mutations were analyzed for each of the passages as mentioned above. One of the diagnostic samples used for transplantation harbored KRAS G12S mutation. The human cells of this patient isolated after the first passage in the mouse carried the same mutation of the diagnosis but with a very low penetration, suggesting a minority clone that decreased further in the second passage. No trace of mutations was found in the third passage. The other diagnostic sample for which serial transplanted samples were analyzed had no KRAS mutation at diagnosis and no new mutations appeared during further passages in the mice. The disappearance of the mutated KRAS subclone during passages in the recipient mice seems to reflect the negative selection for mutated clones observed in patients between diagnosis and relapse. Overall, these data showed that KRAS mutations are frequently occurring in MLL-AF4 leukemias at diagnosis however these mutations do not seem to add a selective advantage to the blast cells. Disclosures: No relevant conflicts of interest to declare.

IntroductionPsychotic disorders significantly contribute to high morbidity and mortality. In high-income countries, the predictors of mortality, relapse and barriers to care among patients with first episode psychoses (FEP) have been studied as a means of tailoring interventions to improve patient outcomes. However, little has been done to document relapse rates and their predictors in patients with FEP in low resourced, high disease burdened sub-Saharan Africa.ObjectiveWe shall estimate the rates of relapse of psychotic symptoms and the factors that predict them in patients with FEP over 4 years.Methods and analysisWe will assemble a cohort of patients with an FEP seen at the Butabika National Mental Referral Hospital in Kampala over a 4-year period. Participants will be adults (≥18 years old), who have received a diagnosis of a psychosis according to the Mini International Neuropsychiatric Instrument (M.I.N.I.), with a demonstrable resolution of active symptoms following the use of antipsychotic medications, and deemed clinically stable for a discharge by the healthcare practitioner. All participants will be required to provide written informed consent. Trained research assistants will collect Demographic and clinical parameters, age of onset of symptoms, diagnostic data using the M.I.N.I., physical examination data, symptom severity, level of social and occupational functioning and household income, during the 4-year study period. We will conduct a verbal audit in the event of loss of life. We shall perform survival analysis using the Aalen-Johansen estimator, and describe the population characteristics by demographics, social and economic strata using simple proportions.Ethics and disseminationAll participants will provide written informed consent. Ethical approvals for the study have been obtained from the Makerere University School of Medicine Research and Ethics Committee and the Uganda National Council for Science and Technology. Findings will be published in peer reviewed journals

I welcome you with most significant pleasure and honour to the Volume 1 Issue 4 of Indian-Pacific Journal of Accounting and Finance. In this Issue 4, the emphasis is placed on accounting, taxation, business administration, corporate governance and risk management, accounting regulation and financial reporting, and accounting.
In the first paper entitled “Board Characteristics, Corporate Performance and CEO Turnover Decisions: An empirical study of listed Non-financial Companies”, Mr Yahya Uthman Abdullahi (Tunku Puteri Intan Safinaz School of Accountancy, Universiti Utara Malaysia), Dr. Rokiah Ishak (Tunku Puteri Intan Safinaz School of Accountancy, Universiti Utara Malaysia) and Dr. Norfaiezah Sawandi (Tunku Puteri Intan Safinaz School of Accountancy, Universiti Utara Malaysia) examine the influence of board characteristics and corporate performance on CEO turnover decisions using a sample of 144 firms from non-financial companies listed on the Nigerian Stock exchange between the periods of 2011 to 2015. The study adopts agency and resource dependency theories to support its objectives and applies a logistic regression statistical technique to analyse the results. The results show that board nominating committee has a significant positive relationship with CEO turnover and board gender diversity has a negative influence on CEO turnover. Also, the study also finds that poor corporate performance leads to CEO turnover. In concurring with the findings, the study suggests to the government to enact legislation on gender quota for more women appointment on the board of the corporation to better the performance of the firm, and as well to enhance the monitoring role of the board.
In the second paper with the caption “Factors affecting the productivity of IRBM Field Tax Auditor: A Case Study in Malaysia”, Mr Sabin Samitah (Tunku Puteri Intan Safinaz School of Accountancy, Universiti Utara Malaysia), Prof Dr Kamil Md Idris (Tunku Puteri Intan Safinaz School of Accountancy, Universiti Utara Malaysia) and Dr Saliza Abdul Aziz (Tunku Puteri Intan Safinaz School of Accountancy, Universiti Utara Malaysia) explore the idea of factors affecting the productivity of field tax auditors in the Inland Revenue Board of Malaysia (IRBM). This study is significant because IRBM has not yet implemented a systematic method of deploying officers to the field tax audit unit throughout Malaysia. The factors identified could be used as a reference in designing future human development programme in IRBM with particular emphasis on field tax auditors. Several variables have been defined, which broadly classified into individual characteristics and external factors. Data for the analysis are sourced from IRBM’s internal database, unpublished records and direct questionnaire of all respondents engaged in the field audit in Klang Valley. The proposed idea would analyse the relationship between auditors’ productivity and various variables based on the initial assumption that all variables are influencing the productivity through direct impact. This is, however, merely an initial expectation and subject to further data analysis once the data collection is implemented and completed.
In the third paper with the title “Knowledge sharing and barriers in Organisations: A conceptual paper on Knowledge-Management Strategy”, Mr Saravanan Nadason (School of Business Management, Universiti Utara Malaysia), Associate Prof Dr Ram Al-Jaffri Saad (Tunku Puteri Intan Safinaz School of Accountancy, Universiti Utara Malaysia) and Dr Aidi Ahmi (Tunku Puteri Intan Safinaz School of Accountancy, Universiti Utara Malaysia) investigates the barriers that give impact towards the knowledge sharing among individuals in organisations. Knowledge sharing becomes the significant part of many organisations’ knowledge-management strategy. Even though the knowledge sharing is signifying practice for organisations’ competitiveness directly and market performance indirectly, several barriers make it difficult for knowledge management to achieve the goals and deliver a positive return on investment (ROI). The barriers were identified through literature reviews. The findings of previous studies revealed that several factors affect the knowledge sharing in organisations. This paper provides the analysis of significant factors that influence knowledge sharing in organisations, which comprise the individuals, culture, technology and organisation.
In the fourth paper entitled “Ownership Structure and Earnings Management of listed Conglomerates in Nigeria”, Dr Musa Adeiza Farouk (Department of Accounting, Ahmadu Bello University) and Dr Nafiu Muhammad Bashir (Department of Business Administration, Ahmadu Bello University) examine the effect of ownership structure on earnings management of listed conglomerates in Nigeria. Ownership structure is represented with managerial ownership, institutional ownership, block ownership and foreign ownership, while earnings management is measured using modified Jones model by Dechow, Sloan and Sweeney (1995). Data were obtained from the six listed conglomerates on the Nigerian Stock Exchange covering the period 2008-2014 through their annual reports and accounts. The findings show that managerial ownership and ownership concentration have a significant and adverse effect on earnings management of listed conglomerates in Nigeria, while foreign ownership recorded positive and significant impact on earnings management of firms, institutional ownership was however reported to have an insignificant but negative influence on earnings management. The study, therefore, recommends that management should be encouraged to have more interest through shares in the organisation as it enables them to have more sense of belonging, which in turn will help mitigate their opportunistic tendencies. Also, the institutional ownership should be improved upon through allotment of more shares as these categories of investors are well informed and could be more vigilant over their stake in the organisation thereby performing monitoring role to mitigate earnings management.
In the fifth paper with the title “Corporate Governance Structure and Firm Performance: A Case Study of Malaysian University Holdings Companies”, Prof Dr Wan Nordin Wan Hussina (Othman Yeop Abdullah Graduate, College of Business, Universiti Utara Malaysia), Dr. Norfaiezah Sawandi (Tunku Puteri Intan Safinaz School of Accountancy, College of Business, Universiti Utara Malaysia), and Dr Hasnah Shaari (Tunku Puteri Intan Safinaz School of Accountancy, College of Business, Universiti Utara Malaysia) analyse the corporate governance structure and performance of Malaysian public university holding companies from 2010 to 2014. The sample comprises eight public university holding companies. Data were obtained by using three methods, namely: survey, semi-structured interview, and documentation review. The board structure and board sub-committees practices of these case organisations were evaluated against the best practice recommendation of (i) the Malaysian Code on Corporate Governance (MCCG) 2012, (ii) the Green Book 2006, and (iii) other relevant acts. The firm performance is measured using four indicators which are sales, profit before tax, net profit margin and return on equity. Overall, their study finds that the practice and structure of corporate governance of the holding companies are excellent. However, their study reveals non-compliance by companies about certain aspects of the recommendations of Malaysian Code on Corporate Governance 2012 (MCCG) and the Green Book. The study also observed that the practice of governance between the university companies is not uniform. The findings provide an insight into the competence of the ministry of higher education as the shareholder to improve the monitoring of the public university holding companies.

Aim: To evaluate the antidiarrhoea effect of hydromethanolic leave extract of I. asarifolia (HLEIA) on castor oil-induced diarrhea.
Place and Duration of Study: Department of Biochemistry, Faculty of Life sciences, Kebbi State University of Science and Technology, Aliero, Kebbi state, Nigeria. P.M.B.1144. Kebbi State. Nigeria, between February 2015 and September 2016.
Methodology: In a continuous effort to search for bioactive agents from medicinal plants, the antidiarrhoea activity of I. asarifolia was investigated. The effect of hydromethanolic leave extract of I. asarifolia (HLEIA) on castor oil-induced diarrhoea, gastrointestinal transit and intestinal fluid accumulation (enteropooling) were assessed in albino rats. Qualitative phytochemical analysis was carried out using standard procedures while acute oral toxicity studies was determined using the staircase method.
Results: The phytochemical analysis showed the presence of alkaloid, terpenoid, tannin, saponin, phenols. The LD50 was estimated to be greater than 3000 mg/kg since there was no mortality recorded after 14 days of acute oral toxicity studies. Sub-chronic administration of graded doses (150 – 600 mg/kg) of HLEIA significantly (p<0.05) reduced diarrhoea episodes, decreased gastro intestinal movement and inhibited intestinal fluid accumulation compared to the control. The antidiarrhoea effect of treated group (600 mg/kg ) was comparable to that of the standard drug Loperamide.
Conclusion: The findings of the present study scientifically validate the use of I. asarifolia in the treatment of diarrhoea.

Full textAbstract:
Abstract Background The rapid growth of mobile technology has given rise to the development of mobile health (mHealth) applications aimed at treating and preventing a wide range of health conditions. However, evidence on the use of mHealth in high disease burdened settings such as sub-Sharan Africa is not clear. Given this, we systematically mapped evidence on mHealth for disease diagnosis and treatment support by health workers in sub-Saharan Africa. Methods We conducted a scoping review study guided by the Arksey and O’Malley’s framework, Levac et al. recommendations, and Joanna Briggs Institute guidelines. We thoroughly searched the following databases: MEDLINE and CINAHL with full text via EBSCOhost; PubMed; Science Direct and Google Scholar for relevant articles from the inception of mHealth technology to April 2020. Two reviewers independently screened abstracts and full-text articles using the eligibility criteria as reference. This study employed the mixed methods appraisal tool version 2018 to assess the methodological quality of the included studies. Results Out of the 798 articles identified, only 12 published articles presented evidence on the availability and use of mHealth for disease diagnosis and treatment support by health workers in SSA since 2010. Of the 12 studies, four studies were conducted in Kenya; two in Malawi; two in Nigeria; one in South Africa; one in Zimbabwe; one in Mozambique, and one in Lesotho. Out of the 12 studies, one reported the use of mHealth for diseases diagnosis; three reported the use of mHealth to manage HIV; two on the management of HIV/TB; two on the treatment of malaria; one each on the management of hypertension; cervical cancer; and three were not specific on any disease condition. All the 12 included studies underwent methodological quality appraisal with a scored between 70 and 100%. Conclusions The study shows that there is limited research on the availability and use of mHealth by health workers for disease diagnosis and treatment support in sub-Saharan Africa. We, therefore, recommend primary studies focusing on the use of mHealth by health workers for disease diagnosis and treatment support in sub-Saharan Africa.

Full textAbstract:
Rice is a weak competitor against weeds and the majority of African farmers have few options and resources available for effective weed control. Weed control is one of the most important and suggestive practices for potential rice production. Field trials were carried out during 2017/2018 dry season at the Teaching and Research Fadama farm of the Kebbi State University of Science and Technology located at Jega (Latitude 12º21ˈN; Longitude 4º36ˈE) and that of Usmanu Danfodiyo University Sokoto located at Kwalkwalawa (Latitude 13º01ˈN, Longitude 5º09ˈE) to study the effects of integrated weed management (IWM) and variety on weed occurrence and the growth of rice. Both locations lie within Sudan Savanna ecological zone of Nigeria. The treatments consisted of six (6) weed management options (Solarization/Orizo-plus (3 WAT)/Hoe-weeding (6 WAT), Round-up/Orizo-plus (3 WAT)/Hoe-weeding (6WAT), Solarization/Hoe-weeding (3 WAT)/Hoe-weeding (6 WAT), Round-up/Hoe-weeding (3 WAT)/Hoe-weeding (6 WAT), Weedy-check and Weed-free) and three (3) rice varieties (Jamila, Faro 44 and Faro 57). The factorial combinations of the treatments were laid out in a randomized complete block design (RCBD) with the split-plot arrangement and were replicated three times. Weed management options formed the main plots while rice varieties were assigned to the sub-plots. The result of the study indicated that combination of solarization, orizo-plus and hoe-weeding achieved an effective weed control (33.56 g weed dry matter per m2) close to the weekly hoe-weeding (16.13 g weed dry matter per m2). Faro 57 variety was noted with the potential to increase rice growth under good weed management practices. From the results, it could be concluded that for increased rice growth, Faro 57 under the combination of solarization, orizo-plus and hoe-weeding IWM option should be adopted.

Weeds are the most prominent of all rice biotic stresses across all the ecologies in terms of yield reduction and increased cost of production. Weed control is therefore one of the most important and suggestive practices for potential rice production. Based on the above, field trials were carried out during 2017/2018 dry season at the Teaching and Research Fadama farm of the Kebbi State University of Science and Technology located at Jega (Latitude 12º21ˈN; Longitude 4º36ˈE) and that of Usmanu Danfodiyo University Sokoto located at Kwalkwalawa (Latitude 130 01ˈN, Longitude 5º09ˈE) to study the correlation between yield and selected parameters of some rice varieties grown in an integrated weed management (IWM) system. Both locations lie within the Sudan Savanna ecological zone of Nigeria. The experiment was done between December, 2017 and August, 2018. The treatments consisted of six (6) weed management options (Solarization/Orizo-plus (3WAT)/Hoe-weeding (6WAT), Round-up/Orizo-plus(at 3WAT)/Hoe-weeding (6WAT), Solarization/Hoe-weeding (3WAT)/Hoe-weeding (6WAT), Round-up/Hoe-weeding (3WAT)/Hoe-weeding(6WAT), Weedy-check and Weed-free) and three (3) rice varieties (Jamila, Faro 44 and Faro 57). The factorial combinations of the treatments were laid out in a randomized complete block design (RCBD) with split-plot arrangement, replicated three times. Weed management options formed the main plots while rice varieties were assigned to the sub-plots. Based on the results of this study, it could be concluded that high weed density in rice field causes poor rice growth and reduces grain yield (r=-0.757). Also, increase in number of leaves, number of tillers, leaf area index, percent productive tillers, length of panicle, weight of panicle and 1000-grain weight resulted to increased grain yield. Therefore, factors that encourage the performance of those parameters can be explored for high rice grain yield.
