Abstract

The increasing budget deficit of the Nigeria’s government in the past few decades with its attendance impact on the economy is worrisome. This study examines the impacts of macroeconomic fundamentals on Nigeria’s fiscal deficit. An error correction model was specified and estimated. In terms of sign and size, the result showed that, there is an inverse relationship between budget deficit and the external reserve. This implies that an increase in the external reserve, leads to a decrease in budget deficits. A unit increase in external reserves resulted in 12.4 percent fall in budget deficit. In contrast, however, national income and interest rate showed a positive relationship with budget deficit. Increase in income expands the potential and propensity to spend. Lenders are equally more disposed to lend to the government because of the presupposed economic prosperity. The lagged value of the error correction term has the expected inverse sign of -0.42, and highly significant. The negative value of the error correction model further supports the co-integration relationship among the variables. Thus, macroeconomic variables influence budget deficits. Economic policies which minimizes macroeconomic fluctuations is paramount in curbing the negative impacts of increasing government deficit in the economy.   Received: 27 February 2021 / Accepted: 24 May 2021 / Published: 8 July 2021

Abstract

This paper was purposed on benchmarking the English language component of the Mature Students’ Entrance Examinations (MSEE) (administered in Ghana by universities to select undergraduate candidates) to the English language component of the West African Senior School Certificate Examination (WASSCE) which constitutes the mainstream Ghanaian university undergraduate entrance examination. The qualitative design (specifically, multiple case study design) was employed for this study. Using the multi-stage sampling technique, six Ghanaian universities (from whom eighteen English language component of the MSEE past questions were elicited) and three sets of the WASSCE English language component past questions administered in 2016, 2017 and 2018) were used for the study. O’Leary’s (2014) eight steps of conducting document analysis were used to analyse the data. The study revealed that there are major mismatches between the two sets of examinations in the areas of the test types, the basic language skills tested and the competences tested. The study advanced, to policy makers, suggestions such as testing Speaking and Listening for the improvement of the two sets of examinations.   Received: 11 May 2021 / Accepted: 14 June 2021 / Published: 8 July 2021

Abstract

Nigerian children under prolonged suffering because of loss of parents are faced with several challenges such as dropping out of school; in some cases, they may even be taken out of school to care for the home.  In this study, we determined the challenges (financial, emotional and psychological) to the education of orphaned and vulnerable children in Eleme Local Government Area of Rivers State, Nigeria. All the 396 orphans in orphanages in the study Area constituted the study population. A Questionnaire captioned “the challenges to the education of orphans and vulnerable children, a case study of Eleme Local Government Areas of Rivers State”, was developed for the study. Whether male or female, the children held that financial situations and emotional stress, to a high extent affected their education. The children attempt to cope with these challenges by being frugal, seeking company among themselves, and trying to develop the ability to manage their emotions. Clearly, the provision of access to finance (e.g., through special bursaries and grants) and guidance and counselling professionals will enhance the continuity and performance of orphans and vulnerable children in the schools.   Received: 4 March 2021 / Accepted: 24 May 2021 / Published: 8 July 2021

Abstract

After months of controversy, the speed limit on two-way secondary French roads without a median strip was reduced from 90 to 80 km/hr on 1 July 2018. Thousands of car drivers and motorcyclists have since protested against this measure, and the present study concerned the latter group. Starting from the Theory of Conditionality in the field of social thinking, which holds that prescriptions are massively conditional, a specific questionnaire based on 23 conditional scripts has been devised. A total of 661 male motorcyclists were asked about the conditions justifying the transgression of the 80 km/hr limit. Results showed that those motorcyclists who exceeded this limit did so by at least by 20 km/hr. A personalized assessment of speed, the pleasure associated with driving, and good road and weather conditions were the most conditional situations, while situations linked to the risk of loss of control were the least conditional. This study suggests that the determinants of risk-taking must be studied at the group and context levels, and that behavior is influenced by the system of social norms. Although this system may conflict with the Highway Code, it reflects an adaptation of the group linked to a need for meaning.   Received: 7 July 2021 / Accepted: 12 August 2021 / Published: 5 September 2021

Abstract

This study examines the effect of corporate social responsibility (CSR) on accrual based-earnings management (AEM) nexus. We employed the use of panel least square analysis to test twenty (20) manufacturing companies quoted on the Nigerian Stock Exchange (NSE) for a period of seven (7) years (2013-2019). The study used corporate social responsibility as the independent variable, earnings management as the dependent variable and firm characteristics variables as the control variable. In utilizing the econometric models unreceptive to endogeneity, our result shows that corporate social responsibility has a positive and significant relationship with accrual based-earnings management. In addition, the study finds that firm size and leverage both have a negative and insignificant relationship with accrual based-earning management while profitability has a positive but insignificant relationship with accrual based-earnings management in Nigeria. The results show that more socially responsible firms have higher quality accruals. This suggests that manufacturing firms in Nigeria are likely to engage more in earnings management while increasing their corporate social responsibility. Hence, managers in manufacturing companies in Nigeria, have a tendency to take advantage of corporate social responsibility practices according to the environment they find themselves in.   Received: 8 July 2021 / Accepted: 8 August 2021 / Published: 5 September 2021

Abstract

Technology has been the bread and butter of learning not only among school going children, but also those of pre-schoolers. Its access and usage has become the perennial tool to generate learning. Hence, it comes with the effects of the learning process. This study attempts to investigate the concern of pre-schoolers’ parents regarding the access of Information Communication Technology (ICT) that takes place both in school and at home. This has also become the cause of concern for parents as their children are exposed to its access and usage, conveniently 24/7. To conduct this study, questionnaires were given and duly completed by 10 parents in a small school of eighteen pre-schoolers. These pre-schoolers ranged from the ages of 3 to 6 years old. At these ages, the children have ICT knowledge, at home ranging from leisure games, electronic toys, mobile phones, television, CD, and computers. They have well educated parents with concerns on child computer addiction, health matters and lack of social values. Discussions on the findings focus on the advantages and disadvantages of technology access and usage among the pre-schoolers. They also included the questions on methods of access control or preventive measures to ensure safe ICT use for these pre-schoolers. This study took a qualitative approach as it was suitable to access the respondents’ perception and opinion via questionnaires. The analysis of the study results indicated that ICT had positive impact on education. The concern and setback for parents were the health issues, dark webs, and lack or over socialising. More often it is lack of social mingling.   Received: 27 June 2021 / Accepted: 9 August 2021 / Published: 5 September 2021

Abstract

Energy is a crucial factor in international relations and a critical input to achieve global economic growth and development. Provision of affordable, sustainable, and reliable energy is necessary and a prerequisite for any country’s economic growth and prosperity. The United Nations Agenda 2030, through its Seventh Sustainable Development Goal (SGD 7) and the African Union Agenda 2063 Aspiration 1recognise the centrality of access to energy towards realising the ambitions enlisted in these documents. The asymmetric distribution of natural resources and the political, strategic, financial, and technological challenges in utilising these resources hinder countries from availing affordable, sustainable, and reliable energy by using domestic sources alone. The inability to attain energy independence makes a compelling case for nations to increasingly integrate their energy supply chains to international and regional energy markets. As a result, ensuring access to affordable energy has become a core interest of regional foreign relations. Therefore, if geopolitics permits, energy cooperation and interdependence become the ultimate and sustainable path towards energy security. Africa has tremendous potential ranging from hydrocarbons to renewable energies. Nevertheless, it has failed to provide adequate energy for its social and economic needs mainly due to poor governance and related challenges. Africa has to utilise such humongous and diversified energy resources by embracing an optimal energy mix that contributes to regional economic development and energy integration. Eastern Africa, home to various renewable energy resources, is one of the energy-poor regions in Africa. The prevailing energy system in the sub-region is hydro-based and lacks reliability. The sub-region has tremendous renewable energy resources such as wind, solar, and geothermal. Still, their utilisation is negligible due to several challenges, including governance and lack of access to finance and technology. This paper argues that an integrated and regional approach to developing the energy sector in Eastern Africa can address the energy-related challenges and contribute towards regional integration in Eastern Africa. In particular, the development of geothermal energy, within the optimal energy mix in the sub-region, for both power generation and direct use application will play a crucial role in forging energy integration in Eastern Africa. In this regard, regional institutions such as power pools and regional economic communities are indispensable.   Received: 27 June 2021 / Accepted: 5 August 2021 / Published: 5 September 2021

Abstract

This study aimed to investigate the role of emotional intelligence in predicting self-efficacy in mathematical thinking. The sample consisted of 150 students selected by cluster and sample random techniques from Al-Buraimi governorate. The tools of the study were: Mathematical Thinking Scale developed by the researchers, Self-efficacy Scale for Children (SEQ-C), and Bar-On Emotional Intelligence scale. The results showed a statistically significant correlation between mathematical thinking, self-efficacy, and emotional intelligence. The self-efficacy predicted mathematical thinking when emotional intelligence was a mediator. The variables of sex and the type of school had an impact on the prediction of mathematical thinking. Based on the results, the researchers recommended attention to the development of psychological factors that contribute to the development of mathematical thinking, including self-efficacy and emotional intelligence. They also recommended that further studies be carried out to investigate the role of different psychological traits in mathematical thinking.Contribution/Originality: this study is one of very few studies that investigated to how much extent that self-efficacy predicts mathematical thinking when emotional intelligence plays a mediating role. This investigation was conducted in a new environment.   Received: 10 June 2021 / Accepted: 10 August 2021 / Published: 5 September 2021

Abstract

Economic organizations operate in a dynamic environment, which necessitates the use of quantitative techniques to make their decisions. Here, the role of forecasting production plans emerges. So, this study aims to analysis of the results of applying forecasting methods to production plans for the past years, in the Diyala State Company for Electrical Industries. The Diyala State Company for Electrical Industries was chosen as a field of research for its role in providing distinguished products as well as the development and growth of its products and quality, and because it produces many products, and the study period was limited to ten years, from 2010 to 2019. This study used the descriptive approach in the theoretical side of the study, on the practical side, the current study used the statistical application (SPSS), and some other statistical means to process and analyze what was collected from data related to the company, the research sample, from its official website. The research concluded that flooding the Iraqi market with alternative imported products for the products of the Electrical Industries Company led to the cessation of production of some of the company's products, as a result, its resources were not invested efficiently and production costs were high. The current study suggested to the Ministry of Electricity to buy the company's products, as these products have a good quality comparing with the foreign ones.   Received: 10 June 2021 / Accepted: 12 August 2021 / Published: 5 September 2021

Abstract

Crime is as old as man and it exists in every society in respective of its level of development. The rate at which criminals operate unhindered in most societies especially in developing countries around the world is worrisome. Crime creates fear and untold suffering among people. Crime often stands as a barrier to socio-economic growth of society, discourages investment, increases the cost of transactions and ultimately fuel migration which eventually creates economic development disparities around the world. The aim of this study is to analyze the manifestation of crime the world over with a view to intimating government of all countries to have a firm control of all criminal activities in their respective countries for a better society. The approach methodology is based on a literature review of scientific journals and reports. Secondary data were sourced from both published and unpublished works as the study applies descriptive method. The main results showed various manifestations of crimes such as banditry, kidnapping, rape, stealing and murder among others. Therefore, crime fuels corruption and destabilizes development of any society.  In conclusion, crime knows no boundary nor personality as it affects people at all levels. This sad activity will continue to be a major factor of lack of socio-economic development if no strong action is taken by governments to effectively tackle the activities of criminals, terrorists and bandits around the world.   Received: 14 May 2021 / Accepted: 5 August 2021 / Published: 5 September 2021
