A Taxonomy of electricity demand forecasting techniques and a selection strategy
Get PDFIn this research, a taxonomy of known electricity demand forecasting techniques is presented based on extensive empirical studies. In addition, a decision strategy for selecting an electricity demand forecasting method has been presented. The strategy has been formulated based on an eight-factor model created by World Bank and inputs gathered from electricity demand forecasting experts (through a questionnaire). The techniques have been assessed based on time horizon, accuracy, complexity, skill level, data volumes, geographical coverage, adaptability, and cost. The experts rated ARIMA (Autoregressive integrated moving average) with exponential smoothing and Kalman filtering as the most adopted method. The next most adopted method is Artificial Neural Networks with preprocessed Linear and Fuzzy inputs. However, now Support Vector Regression may replace this method, which is currently tested by many electrical engineers engaged in electricity demand forecasting. In addition to these highlighted methods, this research also presents the ratings of other techniques based on the eight-factor model of World Bank
Reflecting on the Debates and Action of mixed methods adoption in Business Research: Researchers should start thinking
Get PDFThe purpose of this paper is to evaluate the philosophical arguments underpinning the choice of mixed method [MM] research design. However, the study concluded that mixing research methods in business research is important as it helps to strengthen findings and recommendations arising from a given research study. More so, we recommend for postgraduate researchers to rationalise their choice of mixing methods based on complementarities, research priority, purpose and the implementation of findings and not on the basis of philosophical ontology and epistemology. This has been found to be the reason underpinning the much lauded arguments in the adoption of mix methods
A Study of Value Addition by Information Systems to a Service Providing Business at the Meteorological Services Department in Zimbabwe
Get PDF Many companies are using only a portion of what is needed in terms of Information Technologies (IT) and this has caused the researcher to study how best MSD can effectively utilize Management Information Systems (MIS). The objective that directed the study was to investigate value addition by information systems to a service providing business with specific reference to the weather station in Zimbabwe (Meteorological Services Department). Knowing the value added by MIS to one’s business and working environment is key to cope with the ever increasing challenges such as the volume of information resources, nature and quality of information, user needs and expectations, information and communication technology competencies and infrastructure, inflated cost of information resources and staffing needs. The researcher studied how information systems add value to the daily business of Meteorological Services Department (MSD) in the following areas of the organisation processes: products, quality, management, problem solving and decision of the organisation. The study on value addition by management information systems will assist in the improvement of the MSD in Zimbabwe.The study used a multistage sampling process for drawing sample from the target population. Secondary and primary data collection methods were used for data collection purposes. The source for primary data was questionnaire. Five different types of Management Information Systems that add value to the MSD were identified; Management Information Systems, Office Automation Systems, Executive Support Systems, Expert Systems, Decision Support System and Transaction Processing System. From the findings it was concluded that management information systems add value by allowing valid decisions which provide accurate and up-to-date information and performing analytic functions.This study demonstrated the importance of information systems in an organisation and outlined the fundamental roles of Information Systems (IS) which are to support business processes and operation, support decision making by employees and managers and support strategies for competitive advantage.
Effect of Globalization on Nigerian Financial Sector
Get PDFThe study examined the effect of globalization on the Nigerian financial sector and to ascertain the contribution of globalization on the Nigerian stock exchange and commercial banks. Assets of the Nigerian stock exchange and commercial banks were used as performance indicators. The data used are Nigerian yearly data from 1983 to 2014; the data were analyzed using descriptive statistics, ordinary least square statistical technique, Johannes’s co-integration and error correction mechanism. We used Augmented Dickey-fuller statistics test for stationary. We proxy globalization with degree of openness measured by total trade divided by gross domestic product, foreign direct investment flows, Real Gross Domestic Product, external debt flows, nominal exchange rate and gross capital formation. Two null hypotheses were formulated and were tested. They were rejected based on overall significant of models using F statistics at 5 percent level of significance. The result of our estimate based on overall significant of models using F statistics at 5 percent level of significance shows that Nigerian financial sector as a whole has benefited from globalization. Some of the globalization proxy variables take out a priori signs while some did not. However, the foreign direct investment flows and Real Gross Domestic Product affected the performance of the Nigeria Stock Exchange and commercial banks positively while degree of openness, external debt flows, nominal exchange rate and gross capital formation affected the Nigeria stock exchange and Commercial Banks negatively. This shows that Nigerian foreign trade is low. External debt flow has a negative effect on the Nigerian stock Exchange and positive on commercial banks. Nigeria should discourage external loans. Gross capital formation and external debt flows affected the Nigeria stock exchange negatively. We therefore recommend that the recent re-capitalization and debt recovery exercise and monitoring macroeconomic stability be encouraged to gain confidence by investors in the financial sector.
Determinants of Faculty Retention: A Study of Engineering and Management Institutes in the State of Uttar Pradesh and NCR Delhi
Get PDFQuality education is absolutely essential for the overall development of the human resource base of a country. This requires imparting of appropriate knowledge, skills and values to the students. To achieve this faculty is the main source and instrument. In the present scenario where engineering and management institutes have increased manifold in last two decades, an imbalance between demand for qualified and trained faculty and its supply has emerged. In this situation, the recruitment and retention of talented faculty becomes crucial. However, due to demand exceeding the supply, heavy faculty turnovers is being observed in recent years. The present study examines the major factors on which the retention of faculty depends. To identify the factors on which faculty retention depends, the existing literature has been thoroughly examined and the important factors have been identified. Based on these factors, a questionnaire has been developed, whose reliability and validity has been tested. The developed questionnaire has been administered on management and engineering institutes operating in U.P. and N.C.R. Delhi. Exploratory Factor Analysis (EFC) technique has been used to identify the most significant factors affecting faculty retention. The results of the study could be used by management and engineering institutes to devise strategies for effective use of faculty and their retention.

Determinants of effective Tax Rate of the top 45 Largest listed companies of Indonesia
Get PDFThe capital inflows and outflows of a country are closely related to the established tax rate policy. Tax rate is one of important factors in investment decisions. Evidence that there are variations in effective tax rates amongs firms draw attention of researchers to understand the impact of tax policies on corporate tax burdens (Gupta and Newberry, 1997; Molloy, 1998). Effective tax rate is a dependent variable that is commonly used as a proxy to measure corporate tax burden. This study examined corporate effective tax rates (ETRs) of the top 45 largest listed companies of Indonesia within 2009-2014 (after tax reform of 2008, to be exact). We used two types of ETR1 and ETR2 measures as dependent variables. The first type is the ratio of current income tax expense divided by income before interest and taxes and the second type is the ratio of total income tax expense (current tax expense plus deferred tax expense) divided by income before interest and taxes (Noor et al. 2008).We also used some of independent variables related to firms’characteristics, such as firm size, capital intensity, leverage, returns on assets, and inventory intensity. The statistical results reveal that all independent variables contributed to ETR1 and ETR2 except the capital intensity is not contributed to ETR2. However, the findings provide support for the tax policy on corporate actual tax burdens
Determinants of Non Performing Loans: Evidence from Sri Lanka
Get PDF In the recent past, the global financial crisis and the subsequent recession in many developed countries have increased households’ and firms’ defaults, causing significant losses to the banks. Case of Sri Lanka is no difference. The changes in the economic conditions are believed to have a critical role to play in determining the level of nonperforming loans. Regulators all over the world have started to pay more attention to the credit quality of the Banks and strengthened the regulatory frameworks. This paper attempts to study the macroeconomic determinants of banks’ loan quality in Sri Lanka by analyzing secondary data over the period 1998–2014. The methodology to be adopted for the study was arrived at upon careful review of the literature and following the empirical studies conducted on the determinants of the nonperforming loans. The finding of the analysis is that, out of the six determinants, GDP growth rate and the Export Growth are significant in determining the level of the NPLs in the Sri Lankan banking sector. The relationship of the GDP with the NPL is found to be positive which is not consistent with the majority of the empirical findingsKeywords: Nonperforming Loans, Macroeconomic Determinants,
