With the development of internet, the use of online channels has become a hot issue in manufacturing industry. However, there are hardly any researches have studied the relationship between the innovation of manufacturing enterprises and their use of online channels. This study conducts a hierarchical regression on the basis of 116 answer sheets answered by different employees working in different manufacturing enterprises as research objects, and analysis. The results suggest that the online channel usage of a manufacturing enterprise will have a positive effect on its practice of incremental innovation and the interaction between the company of its customers will be a partial mediator. The results also indicate that the online channel usage of a manufacturing enterprise will have a positive effect on its practice of radical innovation and the interaction between the company of its customers will be a partial mediator

To examine the effects of Political instability (PI) and Covid-19 pandemic crisis measured by death rate (DR) on Tunisian sectorial stock market returns, our paper contributes to the financial literature by providing a new study of these effects based on DCC multivariate GARCH. These effects are specially examined in mean and variance returns equations. Our results show a not significant negative effect of both variables under study in mean but significant coefficients of IP and DR in variance equation. Despite the COVID-19 pandemic crisis positively impacts the investor’s fear sentiments; the conditional volatility of all sectorial stock market returns is higher in political instability period leading high-level risk in Tunisian stock market. Our findings offer useful policy and financial implications to the policy makers also to firms, investors and all stakeholders of the Tunisian stock market

Business intelligence (BI) comprises the strategies and technologies used by enterprises for the data analysis of business information for assisting its management and decision process. The principal aims of this study are: a) to complement the existing literature surveys in the BI area by identifying publications for the period 2007 to 2020, b) to classify these publications according to nine research strategies, c) to classify them according to various well-defined research topic categories, and d) apply machine learning techniques to assess their relevance with the BI field. We have collect 332 papers using ‘Google Scholar’ and a set of related keywords to the field of BI. The results show that most of the papers appeared during the years 2015 and 2017 [1]. The classifications of the literature based on research strategies and research topic indicate that most papers address formal theory and/or reviews and belong to the “benefits” research topic category. Finally, we attempt to increase the accuracy of the classification of aggregated information by utilizing machine learning techniques and estimating the “relevance” with respect to BI discipline. It appears that the overall best individual classifier is the SVM polynomial with ROSE sampling on 80% of the original data using the ‘TDM’ feature space, following by the Neural Networks with ROSE sampling on 80% of the original data using the ‘Topic’ feature space. We furthermore apply various ensemble methods, and we estimate and analyze their performance

This article studies oil price impact on economic growth. So, we shall use two samples namely, oil-exporting and importing countries during the period 1980 to 2019. The impact of oil prices on growth would be modeled by a non-linear model and we shall approximate the economic growth from GDP and we would refer to the four explanatory variables: the energy consumption (EC), the rate of inflation (RI), the stock of capital (SC), the balance of energy (BE). We may estimate the developed model by static technique Panel then we discuss the existence of a linear dynamic after testing the presence or absence of homogeneous and heterogeneous unit roots on Panel Data method. The results show a significant relationship between these two factors and groups

Basel III framework is employed to safeguard the banking sector stability in the international arena. Sierra Leone intends to employ Basel III framework for capital regulation in the banking ecosystem. This article attempts to stimulate discussions on policies to enable Basel III deliver on its goals in Sierra Leone. It elucidates on the significance and plausible strategies for implementing Basel III to facilitate delivery. Within this space the banking sector is anticipated to prop-up capital quality and quantity, propelling minimum liquidity requirement for banks, dampening systemic risks and enabling a smooth transition to Basel III Capital Framework. This study emphasizes a cooling-off period to adopting Basel III framework in Sierra Leone, a fine mix of micro and macro prudential regulations required to be deployed and ; the drive to fortify banks’ balance sheet in lieu of Basel III capital and liquidity framework adoption. This article recommends that the Sierra Leone’s Central Bank should boost market discipline and bolster effective and fficient supervision within the Basel perimeter. The need for cross-border supervision amongst domestics and foreign banks is more so portended. Furthermore, the Central Bank should also stand ready to always protect depositors’ funds and deploy crises management strategies including emergency liquidity support amongst others.

Basic education is vital to the national development. The government of the federal republic of Nigeria invested financial, human and material resources in it so that its objectives could be achieved. However, two decades after its implementation, the nation is yet to overcome most of economic and socio-political challenges it was meant to address. This could be due to poor quality graduates turned out from basic education institutions in particular and all level of education in general. Thus, there is need to investigate the quality management process in education system. Basic education provides the foundation for other levels of education and its quality would determine, to a large extent, the quality of education at higher levels. This paper therefore examines the quality assurance adopted in the implementation of basic education Programme and the extent of achievement of basic education objectives in Kwara and Kogi State of Nigeria with a view to suggesting possible ways of improvement

The study examines the nexus between financial sector development and economic growth in Sierra Leone over the period 1980-2018. The stationarity test result shows that the order of integration of variables included in the model was a mixture of I (0) and I (1). Therefore, the study employs the bounds testing approach to Cointegration and error correction models developed within the Autoregressive Distributed Lag (ARDL) framework to explore the long-and short-run effects of financial sector development on economic growth. The study uses two different measures of financial development including, credit to the private sector and broad money. The study also investigates whether there are other determinants of economic growth. Evidence of short-run dynamics was found amongst the various financial development indicators and economic growth. The results showed that credit to the private sector and broad money influenced economic growth in the short-run. Again, inflation and government consumption expenditure were found to impede economic growth in the short-run. Contrarily, Gross capital formation and FDI were found to stimulate economic growth in the short-run. The study recommends that policy makers should take caution in the choice of financial development indicator as a policy instrument for the attainment of growth and development. Again on the basis of empirical evidence, policies to improve the accessibility of affordable credit by the private sector, including small and medium scale enterprises should be enforced

Increasing agricultural production and productivity of one’s country requires fostering the linkage between the agricultural and non-agricultural sectors that are growing in agriculture does not occur without non-agricultural sectors. The major pulse and oil crops production and productivity in the South Omo Zone is very low in relation to the land coverage due to poor improved agricultural technology utilization and low skill on-farm management practices by producers. To solve the major pulse and oil crops production and productivity problems, strong farmers training centers and research extension system are important. The study was conducted in major pulse and oil crop producing districts of South Omo Zone like Debub Ari, Malle, Bena-Tsemay, Hammer, and Dasenech Districts of South Omo Zone. The major pulse and oil crops grown in the area are haricot bean, field pea, mug bean, ground net, sesame, and sunflower.
