Unemployment Menace and the Fallacy of Microcredit Policy in Nigeria

This study examined the issue of unemployment and the impact of microfinance  banks’ credit facilities on its reduction for the period of 22 years between 1992 and 2014. The study employed secondary data obtained from Central Bank of Nigeria and National Bureau of Statistics. The data obtained was subjected to stationarity and cointegration tests with the use of Augmented Dickey-Fuller (ADF) and  Phillips-Perron (PP) tests. Furthermore, ordinary least square regression was  employed in analyzing the relationship between the dependent variable  (unemployment rate) and the independent variables (microfinance banks’ credit facilities, gross domestic product, interest rate and inflation). The outcomes of the study show that three independent variables (microfinance banks’ credit facilities, interest rate and inflation) at 5% alpha level have significant impact on  unemployment while gross domestic product was found not to have any significant impact on unemployment. The study concludes that credit facilities provided by microfinance banks do not actually go to deserving individuals or borrowers, thus, having no impact on reducing the menace of unemployment in the country. The study therefore recommends that the Central Bank of Nigeria re-evaluate the  performances of the operating microfinance banks in order to ascertain the  proportion of their loan portfolio that actually goes to the “unemployed but creative youths”. In addition, the CBN must as a matter of urgency take necessary action in ensuring that loans granted by microfinance banks are serviced at a single digit  interest rate as applied in countries like Kenya and Bangladesh. This is because  employment generation and overall economic development can only be achieved  when entrepreneurial youths can access credit facilities at affordable interest rate.Keywords: unemployment, microcredit, interest rate, inflation, gross domestic productJEL Codes: E24, G2

Re-examining the casuality between Capital Flight and Foreign Direct Investmen in Nigeria

 The relationship between capital flight and Foreign Direct Investment(FDI) has generated continuous debate in literature. This study aims at providing quantitative analysis of cointegration and causality between capital flight and FDI in Nigeria from 1985 to 2015. The study employed secondary data which was obtained from Statistical bulletin of Central Bank of Nigeria and data base of World Bank.The data obtained were subjected to Units root test, Co-integration test and Pair–Wise test of Granger Causality. The findings of co-integration revealed that the estimated equation and the series are co-integrated. The Granger-Causality test shows that there is no bi-directional causality between FDI and Capital Flight in Nigeria.The study concludes that the success to curtail capital flight in Nigeria is to improve level of infrastructural facilities in the country which can  facilitate increase in domestic investment and also attract FDI. It is recommended that enhancing investment environment by minimizing the obstacles to doing economic activities, and increasing the effort against international financial crime will help reduce capital flight and improve FDI in Nigeria

Growth and yield components of some groundnut (Arachis hypogaea L.) cultivars infected with blackeye cowpea mosaic virus

Blackeye cowpea mosaic virus (BlCMV) is a major virus, infecting legumes with attendant huge losses. Cultivation of resistant varieties is the most effective and sustainable control strategy. Therefore, some groundnut (Arachis hypogaea) cultivars were evaluated against BlCMV in Minna, Southern Guinea savanna zone of Nigeria. The experiment was conducted at the Teaching and Research Farm, Federal University of Technology, Minna. It was arranged as infected and uninfected using Randomised Complete Block Design (RCBD) with three replications. Groundnut seeds were sowed in the second week of August, 2015. Seedlings were inoculated by sap transmission at 10 days after sowing. Disease incidence, severity, growth and yield attributes were recorded. Data were subjected to analysis of variance (ANOVA) and means separated at p≤0.05 probability level. Disease incidence varied significantly p<0.05 from 28.3 to 60.3 % at one week after inoculation (WAI) and 44.7 to 100 % at 2 WAI. ICGV 91317 which expressed mild infection (symptom score = 2) at 9 WAI also exhibited the lowest leaf diameter reduction (3.6 %) at that growth stage. FDRF7-82 which had the lowest reduction in number of leaves per plant at 3 and 6WAI (10.7 and 9.6 %, respectively) also exhibited the lowest reduction in fresh haulm weight per plant (42.2 %). None of the cultivars exhibited consistent reactions, FDRF7-82 and ICGV 91317 had an appreciable combination of growth and yield attributes under BlCMV infection. However, these cultivars could be improved upon either through conventional or molecular breeding by coding with desirable genes. The cultivars which were adversely affected by BlCMV disease could so be improved genetically through appropriate gene introgression from the resistant cultivars.Keywords: Blackeye cowpea mosaic virus; disease incidence and severity; growth and yield; groundnu

Knowledge, attitude, and perception of low back pain and activities that may prevent it among adolescents in Nigeria

Background: Awareness of activities that may result in low back pain (LBP) among adolescents is fundamental in preventing adulthood LBP. Objective: The aim of this study was to investigate adolescents' knowledge, attitude, and perception of LBP and activities that may prevent LBP in Kano, North-western, Nigeria.Methods: This was a cross-sectional survey involving 400 school-going adolescents recruited using a multistage random sampling technique. Data was analysed using descriptive statistics and Chi-square test with 0.05 set as level of significance. Results: The mean age of the respondents was 16.0±1.50 years. LBP annual prevalence was 34.2%, with more girls (31.1%) reporting having LBP compared to boys (28.4%). More than half (59.3%) of the respondents had poor knowledge of LBP and activities that may prevent it. However, they had a good attitude (63%) and perception (74%) of LBP and activities that may prevent it. There was no significant association of levels of knowledge, attitude, and perception of LBP and activities that may prevent LBP with gender, age, and class of study (p > 0.05). Conclusion: Adolescents in Kano, North-western Nigeria had poor knowledge of LBP and activities that may prevent it. Therefore, there is a need to embark on an LBP prevention program among adolescents in Kano, North-western Nigeria. Keywords: Low back pain; prevention; adolescents; knowledge; attitude; perception

HausaNLP at SemEval-2023 Task 12: Leveraging African Low Resource TweetData for Sentiment Analysis

We present the findings of SemEval-2023 Task 12, a shared task on sentiment analysis for low-resource African languages using Twitter dataset. The task featured three subtasks; subtask A is monolingual sentiment classification with 12 tracks which are all monolingual languages, subtask B is multilingual sentiment classification using the tracks in subtask A and subtask C is a zero-shot sentiment classification. We present the results and findings of subtask A, subtask B and subtask C. We also release the code on github. Our goal is to leverage low-resource tweet data using pre-trained Afro-xlmr-large, AfriBERTa-Large, Bert-base-arabic-camelbert-da-sentiment (Arabic-camelbert), Multilingual-BERT (mBERT) and BERT models for sentiment analysis of 14 African languages. The datasets for these subtasks consists of a gold standard multi-class labeled Twitter datasets from these languages. Our results demonstrate that Afro-xlmr-large model performed better compared to the other models in most of the languages datasets. Similarly, Nigerian languages: Hausa, Igbo, and Yoruba achieved better performance compared to other languages and this can be attributed to the higher volume of data present in the languages

Estimation of public radiological dose from mining activities in some selected cities in Nigeria

Mining activities is one of the most significant sources of radiation exposure from long-lived naturally occurring radioactive materials (NORMs), and have resulted in unjustifiable public exposure doses which contravene radiation protection standards. As a result, estimating the extent of such exposure is essential for keeping the recommended public dose limit. This study therefore aims at estimating the public radiation dose around mining areas and its environs in some selected cities across Nigeria. Data on measured activity concentration of NORMs radionuclides comprising of U-238, Ra-226, Th-232 and K-40 from soil round mining areas in some selected cities in Nigeria were extracted from previous literatures and are used for public dose estimation using RESRAD computer code. From the calculated mean activity concentration, the results from each mining locations shows the maximum dose are lower than International Commission on Radiological Protection (ICRP), commended public dosage boundary of 1 mSv/yr with highest dose of 0.91 mSv/yr from Ra-226, Th-232 and K-40 over the period of 47.9 years reported from Gura Top mining site in Jos, Plateau State, while the lowest dose of 0.09 mSv/yr each over the period of 14.06 and 20.27 years occurred at Itagunmodi and Arufu sites for U-238, Th-232 and K-40. The highest dose recorded in Gura Top was due to numerous mining activities in the region. According to the ICRP, there is no safe level of radiation exposure. Therefore, there is need for competent authorities to conduct periodic assessment of radiation exposure from mining sites to ensure that all exposure emanating as a result of such activities are kept below the prescribed dose limit in accordance to the principle of As Low As Reasonably Achievable (ALARA), thereby ensuring public protection from unjustified radiation exposure

Epidemiology of COVID-19 and Predictors of Outcome in Nigeria: A Single-Center Study.

There is a paucity of information regarding the epidemiology and outcome of COVID-19 from low/middle-income countries, including from Nigeria. This single-center study described the clinical features, laboratory findings, and predictors of in-hospital mortality of COVID-19 patients. Patients admitted between April 10, 2020 and June 10, 2020 were included. Forty-five patients with a mean age of 43 (16) years, predominantly male (87%), presented with fever (38%), cough (29%), or dyspnea (24%). In-hospital mortality was 16%. The independent predictors of mortality were hypoxemia (adjusted odds ratio [aOR]: 2.5; 95% CI: 1.3-5.1) and creatinine \u3e 1.5 mg/dL (aOR: 4.3; 95% CI: 1.9-9.8)
