The article explores challenges associated with the teaching of Civic Education in Social Studies lessons at junior secondary school. An interpretive study was conducted which employed hermeneutic phenomenological approach. The sample size for the study was 12 comprising 2 females and 10 males drawn from the Ministry of Education district office and selected primary and secondary schools. All the participants were selected using homogenous purposive sampling. The data that was generated through semi structured interviews, observation schedules and document analysis was thematically analysed. The study established that there were many challenges associated with the teaching of Civic Education through Social Studies lessons. Some of them were shortage of qualified Civic Education teachers, a dearth of teaching/learning materials such as textbooks and computers. Also, substandard textbooks, shortage of desks, inadequate contact time and low literacy levels among learners among others. Based on the above highlighted challenges, the study recommended that Ministry of Education should employ adequate qualified Civic Education teachers. It was also recommended that Ministry of Education should allocate adequate funds to schools for the procurement of teaching/learning materials as well as enhancing field studies in order for learners to supplement on theories learnt in the classroom environment. Further, it was recommended that Ministry of Education should build and procure more school infrastructure.

The impact of Covid-19 pandemic has been devastating on the global economy, national economies, institutions and indeed organisational operations. One of the key organisational operations that has been impacted by Covid-19 is human resource management (HRM). The impact of Covid-19 on HRM in organisations has been reported to have covered all the key functional areas of human resources practice ranging from the governance of HRM practice to workplace environment. This development has influenced the world of work profoundly. This study conducted on the impact of Covid-19 on HRM functions in Zambian organisations has revealed the continued negative impact of Covid-19 on organisational operations. However, the results of the study indicate that while all the HRM functions that were investigated namely: Organisation Design and Development; People Resourcing; Performance Management; Training and Development; Reward Management and Employee Relations reported to have been impacted, only two functions namely Training and Development and Performance Management reported significant negative impact having scored 77% and 48% respectively. The rest of the functions namely: Organisation Design and Development; People Resourcing; Reward Management and Employee Relations scored 35% and below, scores that indicate some relative stability in the operations of the functions. These results suggest the availability of a relatively stable operational environment of HRM functions in Zambian organisations and that the role of HRM function in the organisations has remained stable despite the on-going challenges posed by Covid-19. The prevalence of such an operational environment is critical for business operational continuity amidst the Covid-19 pandemic.

Objective: This study was carried out to investigate the effect of the ethanolic leaf extracts of Carica papaya (C. papaya) and Newbouldia laevis (N. laevis) on the lipid profile of alloxan-induced Wistar rats. Methodology: Forty (40) male wistar rats weighing 130-150g were procured and acclimatized for two weeks, after which they were divided into eight (8) groups of five (5) rats each, and were housed in cages. The groups were designated as groups A, B, C, D, E, F, G and H. Groups B – H were induced with diabetes using alloxan. Group A served as the control group and received only distilled water; group B diabetic received only distilled water only, while groups C – H diabetic received 400mg/kg of C. papaya, 600mg/kg of C. papaya, 400mg/kg of N. laevis, 600mg/kg of N. laevis, 200mg/kg of C. papaya + 200mg/kg of N. laevis and 300mg/kg of C. papaya + 300mg/kg of N. laevis respectively for 21 days through oral route with the aid of oral gastric tube. On the 22nd day, the animals were sacrificed by chloroform inhalation, and blood samples were obtained through cardiac puncture for lipid profile parameters’ assays. Data obtained were analyzed using SPSS version 25 and (P<0.05) was considered significant. Result: There was significant increase in the plasma total cholesterol, triglycerides, low density lipoprotein (LDL) with a decrease in plasma high density lipoprotein (HDL) of the animals in group B when compared with the control group. These effects were ameliorated in Groups C – H that received the variable doses of the ethanolic leaf extracts C. papaya and N. laevis with more positive effects on the groups that received the combined ethanolic leaf extracts. Conclusion: The leaf extracts of C. papaya and N. laevis have ameliorative effects on the lipid profile alloxan-induced diabetic Wistar rats.

DOI : 10.51244/IJRSI.2022.9201This research studied external debt and macro-economic performance in Nigeria from 1981 to 2019. The macro-economic performance indicators employed were Real Gross Domestic Product, and Inflation rate while external debt stock was the explanatory variable. The study employed the cointegration and Vector Error Correction Model as the main analytical tool. The findings revealed that a significant positive relationship existed between external debt stock and inflation ratein Nigeria while external debt stock decreased Real GDP. The study also found that shocks to external debt stock decreased real GDP initially but grew subsequently at a slow pace. The external debt stock contributed to the macro-economy in the VEC model was very minimal as they contributed less than 20%. The study concluded that Nigeria’s external debt had negatively affected the macro-economy and also, external debt stock increased inflation rate thus indicating a serious strain in the macro-economy occasioned by continued debts without a corresponding debt servicing. Thus, we recommended that the government can utilize external debt to decrease the rate of inflation through government focus on productive sectors and channeling of public investments to the real sector. Also, Nigeria should focus more on the real sector which is the productive sector of the economy so as to create a long term external debt service plan and ease the strain on exchange rate and the macro-economy

An study into the financial performance of property and real estate firms that are publicly traded on the Indonesian Stock Exchange from 2016 to 2020 was conducted. There have been a number of previous financial performance studies. In order to re-examine the theory of financial performance, additional study is required. A total of 52 property and real estate companies participated in the survey. Purposive sampling was used to collect data from 29 sample companies over a five-year period (2016-2020), resulting in 145 observations. The information for this study came from a list of firms that could be found on the website of the Indonesian Stock Exchange. The data is analyzed through the use of multiple regression analysis. Following the traditional assumption test, multiple regression analysis and hypothesis testing are performed, respectively. Financial performance is influenced by a number of factors, including capital structure, firm size, and total asset turnover. The capital structure has a significant negative impact on the financial success of a company. The size of a company has minimal impact on its financial performance, but the overall amount of assets it has does.

This paper investigated the effectiveness of monetary policy in controlling inflation in Nigeria using secondary annual data spanning from 1981 to 2019. Specifically, the paper examines if there exist any form of relationship between monetary policy and inflation in Nigeria. Money Supply, Treasury Bills Rate, Monetary Policy Rate and Exchange Rate were the variables used in the study to check inflation. The paper employed Johansen cointegration method to check for the long run relationship between the variables. Ordinary Least Square (OLS) was adopted because of its property of Best Linear Unbiased Estimator. The Johansen co- integration test revealed the existence of long-run relationship between the variables. However, the empirical result of the OLS test showed that monetary policy rate, money supply and treasury bill rates exert influence on inflation in Nigeria. While exchange rate depreciation leads to inflationary growth. This result is consistent with the prediction of economic theory. The study therefore concluded that money supply, treasury bills rate, monetary policy and exchange rate had influence on inflation within the period under consideration and recommends that monetary authority should put in place schemes to make them more effective perhaps by offering competitive rates and the nation Nigeria shift from being a consumption driven (import) economy to production based (export) economy for the impacts of these policies to achieve desired results.

The public sector is widely recognised as one of the strategic providers of goods and services to ameliorate public welfare. Besides this, the public sector also formulates and implements macro-socio-economic policies to create a predictable, consistent and transparent investment climate. However, the advent of COVID-19 pandemic abruptly in late 2019 in China has undoubtedly reconfigured the traditional working landscape of the public sector internationally. Zimbabwe is no exception. One ponders how Zimbabwe weathered to this magnitude global catastrophe to be ahead of the curve and stay operational since its traditional practice were almost made redundant. There is still paucity of literature on COVID-19 pandemic and public sector governance. Hence, this paper assessed the impact of COVID-19 pandemic and government regulations to the public sector practices in Zimbabwe. It also evaluated the efficacy of COVID-19 preventative measures in suppressing the virus. This paper was largely qualitative study hinged on document analytic approach and snap survey. This paper argued that for public sector institutions to cope with the ‘new normal’, they should strategically rethink its philosophy of public sector practices. Analysis of recent literature that show that this global threat has unprecedentedly forced the government to trim its workforce to work physically and deferment of development projects as well as caused deaths of critical expertise and loss of revenue, among others. Debatably, the advent of COVID-19 pandemic is a wake-up call for Zimbabwe to learn some critical lessons and insights to capitalise on new opportunities presented to modernise its practice. Even though innovative digital strategies were adopted minimally, this paper further recommends that the public sector institutions should strengthen the espousal of contemporary digital systems sustainably to stay afloat in hard times of this crisis and post-COVID-19 bane.

The role of financial development in the growth and development of developing economies have constituted a popular discourse among development and financial economist. Two key issues of interest in the discussion of financial are competition and concentration in the banking industry as key predictors of growth in every economy. This study therefore investigated the effect of concentration and competition in the Nigerian banking industry on economic growth with focus on the big-8 banks in Nigeria. Moreover, the implementation of the consolidation policy of the Central Bank of Nigeria in the year 2005 informed the choice of period (i.e., 2005-2019) selected for this study. While a positive concentration-growth nexus was found in the study, the study could not establish a positive competition-growth nexus in the Nigerian economy for the period under review. The increase in capital base as required by the consolidation policy has accounted for the level of concentration in the banking industry; and this has made it easier for banks to contribute significantly to the growth of the economy. Imperfect competition in the banking industry on the other hand has led to higher costs of loans that detain firms from new investments, thus slowing down the firms’ expansions and productivity growth.

DOI : 10.51244/IJRSI.2022.9204High level of exclusion from the financial system could be a consequence of low level of financial development evident in such economy. Low financial access and access to financial services/products is a one of the contributory factors to the level of income generated by households and businesses and by extension the level of income inequality in such economy. To examine the “Financial Inclusion-Income Inequality” nexus in Nigeria, this paper specifies income inequality in Nigeria as a function of deposit money banks’ loans to SMEs, banks’ credit to the private sector, number of bank branches, and broad money supply-to-GDP ratio. The data used in this study are annual time series data from 1992 to 2018. Specifically, data on financial access (measured by having a number of commercial banks branches and broad money supply-to-GDP); and access to financial services and products (measured by deposit money banks’ loans to SMEs and deposit money banks’ credit to the private sector) were collected from the Central Bank of Nigeria (CBN) Statistical Bulletin. Data on level of inequality (measured by the Gini index) was collected from the National Bureau of Statistics (NBS). The unit root tests (i.e., ADF and PP) shows that the time series are non-stationary until after first differencing. To empirically analyze the impact of financial inclusion on inclusive growth, the Dynamic Ordinary Least Square (DOLS) econometric technique was employed. The results show that the coefficients of financial access variables are significantly different from zero. That is, the improvement in the financial access component of financial inclusion will prove to be more effective in reducing the income inequality gap in Nigeria. This may not be unrelated to the reality on ground as it affects the cost of credit and the stringent requirements often included as pre-condition for granting of loans and supply of credits by deposit money banks and other business financing institutions. This paper therefore recommends policy that increases awareness among citizens on the importance of owning and maintaining a bank account; and establishment of more branches in the rural areas to serve the high and growing rural population.

DOI : 10.51244/IJRSI.2022.9205Introduction: Hypertension is a non-communicable disease that is an important public health problem in the world because its prevalence continues to increase and is the third biggest risk of premature death. Lifestyle is the most important risk factor that can cause hypertension, including physical activity, diet, smoking behavior, rest patterns. The purpose of the study was to determine the effect of lifestyle on the incidence of hypertension in the elderly during the Covid-19 pandemic era. Materials and Methods: The research design uses a quantitative case-control design approach. A sample of 88 respondents consisted of 48 cases and 40 controls. Sampling method using accidental sampling technique, the instrument used is a questionnaire, data collection method using interviews, data analysis using chi-square test and multivariate logistic regression. Result: The results showed that there was a significant effect between physical activity (p-value 0.047), diet (p-value 0.012), smoking behavior with the incidence of hypertension (p-value 0.001), and there was no effect of rest patterns with the incidence of hypertension (p-value 0.001). p-value 0.334). Multivariate analysis found that smoking was the most influential factor with the incidence of hypertension (OR=6,647), meaning that respondents who had smoking behavior had a 7 times greater risk of suffering from hypertension than respondents who did not smoke. Conclusion: There is a significant influence between physical activity, diet, and smoking behavior with the incidence of hypertension and there is no effect of rest patterns with the incidence of hypertension. Smoking behavior is the most influential factor in the incidence of hypertension.

The recent research evaluates regional and household food insecurities experiences on human persuaded or induced hazard with potentials for replication in other sub communities of the country and further afield in Africa. The research underpinned on theoretical framework to explain the severity and natural surrogates inducing food insecurity and considerable approaches for realization of sustainable food security. Primary and secondary data sources were employed. Whereas the former sources include structural questionnaire and interview surveys, the later sources comprises of relevant literature such as books, journals and conference report etc. The gathered dataset was collated and analysed using statistical percentage and regression. The findings established that climatic induced hazard such as extreme temperature, flooding, drought, riverbank erosion and high wind served as an agent of disaster and triggers food insecurity in the regions or six (6) geopolitical zones of Nigeria owing to what they offer to the environment and human settlement. The research later pointed that vigorous relationship exists between food insecurity and depression problem of many households heads at significant score of (P>0.05).

The combination of piles and raft foundation is known as piled raft foundation. Piled raft foundations have proven to be more cost-effective and capable of meeting safe bearing capacity and serviceability norms in the case of high-rise buildings on cohesionless soil. The behavior of a stacked raft foundation is influenced by the piles, raft, and soil. The stacked raft system’s bearing capacity is improved and settlement is minimized when the ground beneath the raft foundation bears the burden of supporting the applied loads. The piled raft foundation minimizes total settlement and improves bearing capacity more than the raft foundation.
When isolated footings cover more than 70% of the building area under a superstructure, raft foundations are used, and the present study focuses on the vertical load bearing capability of piled raft foundation systems on cohesionless soil for concentric loading. The use of strategically positioned piles increases the load capacity of the raft while reducing differential settlement. The present study sheds some light on the use of piles as raft foundation settlement reducers, as well as the behavior of a piled raft in sand. A series of small-scale model experiments were carried out. The present investigation studies by varying pile length and alignment on the ultimate load of piled raft foundation. The results indicate that for a 10mm raft thickness, installing 4 piles, 6 piles, and 9 piles by varying L/D ratios of 5,10,15,20 carries significant load. In this present work for a 50mm length of pile, and the value of load improvement ratio increases by 36 percent, 60 percent, and 68 percent, respectively, when compared to plain raft.Page(s): 113-118 Date of Publication: 24 March 2022
DOI : 10.51244/IJRSI.2022.9207Cassava peel is an agro-waste product produced in the processing of whole cassava roots into different food and industrial products in Nigeria. The use of cassava peel as feed for non- ruminant animals is limited by its high crude fibre and hydrocyanic acid contents but low protein content. To improve its nutritional potential as energy source, an experiment was conducted to examine the effect of ensiling periods on the proximate compositions and hydrogen cyanide contents of wet cassava peel meals. Wet cassava peels were ground into meal using an attrition mill and divided into 4 batches. The first batch was sundried immediately after grinding while the second, third and fourth batches were sundried after ensiling in black polythene bags kept under room temperature for 7, 14 and 21 days, respectively. Ensiling significantly (p<0.05) increased the dry matter contents of the meals with the 14 days ensiled meal having the highest value. The un-ensiled and 7days ensiled samples had similar and significantly (p<0-05) higher crude protein values than the 14 and 21 days ensiled samples. The 21 days ensiled sample had lowest crude protein (3.36%) and ether extract (4.44%) values but highest crude fibre (17.10%), ash (20.19%) and NFE (54.09%) values that were significantly(p<0.05) different from other treatment groups. The 14days ensiled sample had the highest calculated ME (2466.86kcal/kg) value that differed significantly (p<0.05) from the other treatment groups. HCN concentration was lowest (p<0.05) in the 21 days ensiled sample (0.20mg/kg). It is concluded that the period of ensiling wet cassava peels meal affected its proximate compositions and HCN contents, and that ensiling for 14 days resulted in higher DM, fat and energy values and should be encouraged.
