How university students in South Africa perceive their fathers’ roles in their educational development

The larger study that has influenced this article was designed to explore what influenced rural men’s capabilities to actively participate in children’s early social development and its impact on transition to adulthood among their university-going children. Studies have established an increase in the level at which fathers in South Africa have been found wanting in terms of supporting their children’s development at early stages in their lives. It has been reported that this unacceptable behaviour can be transmitted or carried over from one generation to the next. There is the belief that the majority of the young male children who experienced non-supportive fathers will grow up repeating this behaviour with their children. This calls for a study on the perceptions of young people about what fatherhood is all about, hence this study. This study used a descriptive survey with a sample size of 300 students studying education in one university in the Eastern Cape Province. A 25-item questionnaire titled Perception of Fatherhood by University Students (α = 0.75) was used to collect data that were analysed using descriptive and inferential statistics. The participants perceived that the experience and level of education influence men’s perception of fatherhood positively. Extra‑curricular programmes for proper fatherhood transition of young boys are recommended, commencing from Grade 1 through to Grade 12, to expose them to the kinds of dispositions that will enable them to be responsible fathers. There is also a need for compulsory empowerment programmes such as for designers, artists and sportsmen and other semi-skilled professions for male children who cannot acquire higher education to strengthen them socio-economically to provide education for their children

Transformation and decolonisation of mathematics education for sustainable development: A case study of its learning trend in Nigeria

the quest to contextualise education in Africa has been on-going for a while and many countries have been making efforts towards it. During this time of educational review, conscious efforts should be made to identify problematic levels of some subjects that are dreadful to the learners to pave the way for curriculum re-design for context appropriateness. Mathematics learning in African countries has been a source of concern to all educational stakeholders despite several efforts towards its deconstruction. An examination of performance trend in the subject might reveal at what point the learning started declining and this will suggest intervention towards decolonisation of its content. This study measured the academic performance of pupils from preschool level up to the end of primary education (VI class). A descriptive survey research design was adopted and 720 Primary VI pupils were selected through multi-stage sampling technique in a state in Nigeria. Primary School Mathematics Performance Record Sheet (PSM_PRS) was used to collect mathematics scores from preschool through Primary VI class. Data were analysed using descriptive statistics and graphs. Pupils started experiencing major declines in mathematics from Primary III class. Results also indicate no significant difference in the class where male and female pupils’ performances started declining. Therefore, there is the need to review and contextualise mathematics content from third year in primary/elementary school for effective learning. Activity-based and exploratory strategies using contextual experiences and resources to deliver mathematics lessons were recommended for third year in primary/elementary schools and beyond

Zika virus and birth defects: an obstetric issue

Zika virus is an emerging mosquito-borne virus that is relatively unknown, unstudied and under-diagnosed, but has potentials to spread to new geographical areas that favour survival of Aedes mosquitoes. It is associated with an alarming rise in babies with microcephaly that require much care and support with a lot of financial assistance. This is a review article on Zika virus and birth defects; a worrisome issue in today’s obstetric and medical practices. Since Zika’s discovery in Uganda, the virus was known to occur within a narrow equatorial belt from Africa to Asia with no or mild symptoms. It has emerged as a global public health threat over the last decade with accelerated geographic spread of the virus in the last nine years. The risk of Zika virus to the fetus is poorly understood, difficult to quantify and problematic. The causal link between Zika virus and microcephaly was initially speculative, strongly suspected and scientifically unproven. However, on 13th April, 2016, it was concluded that Zika virus is the cause of microcephaly and other severe fetal brain defects. The Center for Disease Control and Prevention (CDC) authors reviewed and weighed evidences using established scientific criteria to conclude after a careful review of the report published in the New England Journal of Medicine. There is no prophylaxis, treatment or vaccine to protect against Zika virus infection. However, preventive personal measures are highly recommended to avoid mosquito bites

Determinants of Choice of Storage Systems for Root and Tuber Crops in Benue State, Nigeria

Determinants of Choice of Storage Systems for root and tuber crops in Benue State of Nigeria were examined. The specific objectives were to determine the factors affecting choice of storage systems by root and tuber crop farmers; and determine the relationship between choice of storage systems and farm productivity. Data were collected from 288 root and tuber crop producers in eight Local Government Areas and 32 wards, using a multi-stage sampling technique. Structured questionnaire was used to collect the data. Data collected were analysed using logit model and Mann-Whiney U test. The results indicate that total output, gender, educational level, household size, and farm size significantly affect the choice of storage systems by root and tuber crop producers. The results also reveal that the output of farmers who utilized only the local storage systems exceeds those who utilized both the local storage systems in addition to the modern storage techniques. It was recommended that strategies and policies aimed at encouraging root and tuber crops farmers to adopt a particular storage technique should take into consideration their socio-economic characteristics. Also research efforts aimed at improving the effectiveness of the local storage systems using locally sourced materials should be encouraged

Gynaecological bacterial infections: the physical and psychosocial consequences and challenges of management in resource-limited settings

Gynecological bacterial infections (GBIs) are prevalent in our environment and as a result pose a number of physical, social and psychological consequences. These infections are acquired through several ways. Treating GBIs is a daunting task making its control the most important strategy to alleviating its physical and psychosocial consequences. To highlight the physical, social, and psychological consequences of gynaecological bacterial infections in our resource limited setting. To highlight the hugely unresolved challenges associated with the management of gynecological bacterial infections in our resource-limited setting. Several databases (Medline, Google Scholar, Pubmed, WHO’s Hinari and Wikipedia) and some selected websites were searched using the following keywords: gynecological infections, vaginal infections and discharges, vaginal flora, sexually transmitted infections, pelvic inflammatory disease, syndromic management and challenges, psychosocial consequences, alternative medicine. A total of 5470 relevant articles were obtained between 1947 and 2018. Out of these only 256 relevant articles on the topic were reviewed. However, 213 were dropped for having an incomplete submission. Forty-three (43) articles were fully accessed and referenced. The high prevalence of GBIs poses a lot of burden on the reproductive and socio-economic lives of our women. This should be matched by behavioral changes, prompt diagnosis and early treatment; facilitated by accessible and affordable health care through improved government funding

Analysis of Electrical Porcelain Insulators from Local Clays

This paper focused on the chemical analysis of electrical porcelain insulators based on local clays. Test samples were made by conducting some chemical composition test using the Atomic Assumption Spectrophotometer (AAS). The clay samples were also tested for linear shrinkage and apparent porosity. Based on the results obtained, the linear shrinkage values recorded range from 7.29% to 14.29% for Iva Valley formulations, 5.14% to 14.71% for Nawfija and 7.74% to 10.29% for Ekwulobia. It was observed that linear shrinkage decreases as the content of non-plastic materials increases and increases as clay content increases. Iva Valley formulation recorded porosity values ranging from 8.84% to 20.80%. For Nawfija formulation, porosity values range from 10.81% to 17.30% while Ekwulobia formulations gave porosity values ranging from 9.52% to 16.82. Porcelain insulators that constitute the above results were found to have requisite properties that make them suitable for domestic production of porcelains insulators from the clay samples studied

Mycotoxicology Society of Nigeria Mycotoxicology, 2015, 2: 28-34 Mycotoxin Contamination of Maize and Guinea corn from Markets in Plateau State, Nigeria

ABSTRACT Maize (Zea mays) and guinea corn (Sorghum bicolor) are major food items in Plateau state, Nigeria. A multistage sampling technique was used to select the markets and store/warehouses used for this study; sample collection employed a simple random sampling method from different sampling points within designated areas. A total of 18 representative samples were collected and analyzed for the following mycotoxins: aflatoxins (Aflatoxin B 1 -AFB 1 , Aflatoxin B 2 -AFB 2 , Aflatoxin G 1 -AFG 1 and Aflatoxin G 2 -AFG 2 ), fumonisins (Fumonisin B 1 -FB 1 and Fumonisin B 2 -FB 2 ) and cyclopiazonic acid (CPA). Out of 12 samples analyzed for Aflatoxins, AFB 1 was detected in 5, AFB 2 in 1, AFG 1 in 1 and AFG 2 in 6 samples respectively. The highest concentration of AFB 1 and AFG 2 were found in maize samples from Pankshin market. Only maize samples from Mangu market were contaminated with AFB 2 and also harboured the lowest concentration of AFG 2. AFG 1 contamination occurred in only guinea corn from Shendam market. and FB 1 was detected in all 18 samples analyzed. The mycotoxin CPA was not detected in any of the samples. Aflatoxins levels in analyzed samples were regarded as safe based on Nigerian and European Union maximum permissible levels of 4µg/kg. With the exception of two samples, FB 1 levels in analyzed maize samples were within European Union maximum permissible levels of 1,000 to 3000µg/kg. The health and food safety implications of these results for the human and animal population are further discussed

Application of High-Voltage, Precision, Low-Power Max9943/Max9944 Operational Amplifier in Industrial Process Control Using ±20ma OR 4-20ma Current-Loop Systems

This article explains how to apply a high-voltage, high-current-drive operational amplifier to convert a voltage signal into a ±20mA or 4–20mA current signal for use in process-control industrial applications. The MAX9943 op amp a family of high-voltage amplifiers that offers precision, low drift, and low power consumption device was used as case study]. Experiments are described and test results presented. Current loops are known for their high immune to noise compare to voltage-modulated signals, a feature that makes it ideal for use in a noisy industrial environment. This signal can travel over a long distance, sending or receiving information from remote locations. A current loop typically includes a sensor, transmitter, receiver, and an ADC or a micro-controller (figure 1). The sensor measures a physical parameters such as pressure or temperature and provides a corresponding output voltage. The transmitter converts the sensor's output into a proportional 4mA-to-20mA current signal, while the receiver then converts the 4mA-to-20mA current into a voltage signal output. This receiver's output is then received, interpreted and converts into a digital signal output by an ADC or a micro-controller. Experiment performed using the relationship the relationship stated in equation 5, shows that if the input voltage level rise above or fall below ±2.5v, the op amp device attains its saturation point and its output voltage can no longer increase. As shown in figure 3, where the curve flatten and no longer follow the ideal linearity characteristics that was supposed

A Review of Environmental Effects of Surface Water Pollution

Water is life without pollution, but death when it is polluted. The objective of this study is to conduct a literature review of environmental effects of surface water pollution. The method used for this study is a review of academic journal articles, internet materials, textbooks, bulletins, conference papers, project reports and publicly available materials on the environmental effects of surface water pollution. All previous authors whose works were reviewed agreed that anthropogenic activities greatly contributed to surface water pollution and spatial variation of physicochemical parameters over time and location more than other sources in terms of both chemical and physical water pollutants that indicated elevated values of major chemical parameters (lead, cadmium, chromium, copper and some anions) beyond the permissible/threshold limits set by regulatory bodies. They also had a unity of opinion that the parameters have adverse effects on human plants, aquatic and physical environment. From the review and based on the results of the previous studies, this study concludes that most surface waters across the globe are polluted and as such must be treated before use both for domestic and industrial purposes to avoid the spread of epidemics that can lead to deaths of humans who are the most precious of all creatures. Recommendations of the study include: (1) regular review of environmental effects of surface water pollution by researchers to indicate the trend in pollutional loads of rivers and streams across the globe; (2) strict enforcement of regulations water quality standards and (3) regular monitoring of the environments of water bodies by regulators and the locals

A Review of Housing Problems

Housing problems occur both in rich and poor communities across the globe. The objective of this research is to review housing problems which lead to unwholesome environmental conditions. The method used is a review of academic articles, textbooks, internet materials, news articles and publicly available materials on housing problems. Previous authors whose works were reviewed have a convergent view on housing problems including overcrowding and congestion, poor accessibility, substandard and inadequate housing, high cost of building materials, high interest rate and lack of interest by financial institutions to facilitate loans to investors and uncoordinated policies by government. The paper made the following recommendations: (1) government should build low-cost houses to cater for the large number of people who, due to their low-income earnings could not afford a decent apartment; (2) formulation of economic, social and environmental policies that facilitate housing that is both affordable and sustainable by government; (3) improvement of sanitation in poor neighborhoods with poor housing conditions through urban renewal programme
