On the Time Series Modelling of Crude Oil Exportation in Nigeria

[Abstract] [Full-Text PDF] [html]

Abstract: The research result showed there was a general increase in production over time (production was mostly below 60million barrel per month in 2002 while in 2011 no production per month was less than 64 million barrel) showing that trend exists in the data, the simple average method was used to check for seasonality, the minimum value was 93.34 while the maximum was 104.92 none of which was too far from 100% showing there was no seasonal variation. The AIC as well as Mean Square Error (MSE) settled for ARIMA (1,1,1) out of the four initial picks and its was therefore chosen as the best model fit for the data collected for forecasting purposes and for policy formulation. ARIMA (1,1,1) was used to forecast for the year 2011 and its showed that by January the production was 75.02 million barrel and by december production was about 67.25 million barrel, though its a wide difference from the actual value but was still chosen because of its simplicity to use and that its also has the lowest standard error after the forecast. ARIMA (1,1,1) was used to predict for short-term purpose, therefore the year 2012 was predicted and it revealed that the minimum production for 2012 should be around 66.63 million barrel and the maximum production should be around 68.83 million barrel.

The Comparison of the Performance of ARIMA and MA Model Selection on Road Accident Data in Nigeria

[Abstract] [Full-Text PDF] [html]

Abstract: In this research work, time series model selection was performed by given consideration for a number of models that most suitable for the incidence of accident cases in Nigeria. Among the candidate models considered are the Autoregressive Integrated Moving Average (ARIMA) and Moving Average (MA) models each at various parameters specifications. Results from this work showed that the best models that are suitable to describe the accident cases in Nigeria are the ARIMA(3,1,1) and MA(0,1,2) according to the Mean Square Error (MSE) and Akaike Information Criteria (AIC). National data set on cases of accident in Nigeria primarily collected by Federal Road Safety Commission (FRSC), Nigeria from 2004 to 2011 was employed in this research.

Research Design and Sampling in Social and Management Sciences in 21st Century

[Abstract] [Full-Text PDF] [html]

Abstract: This paper presents an overview of research design and sampling as a sine qua non for conducting researches in the area of social and management sciences (SMS). Ineffective research design and sampling are usually the bane of successful and logical conclusion of researches with valid useful findings and inferences for decision making. The paper was motivated by the desire to provide a study and/or teaching/training materials on research design and sampling procedures in the 21st century that will be easily understood and applied by researchers, including undergraduate and postgraduate students, trainers, trainees, teachers and a wide non-specialist audience. Through intuitive and qualitative reasoning, the paper explores the conceptual, theoretical and empirical technical issues on the requirements, classification, types, methods and processes of research design and sampling. Data collected from 98 research experts and analyzed with one-way ANOVA at 5% level of significance show that researches before and during the 21st century are the same. Also SMS researches in the 21st century are usually Information and Communication Technology (ICT) driven. Technological advances need to be incorporated in the research process in order to facilitate and expedite conducting researches for the realization of objective functions. Review of research design and sampling procedure prior to implementation, exploring and application of latest computer software and adherence to specifications are advocated for timely, quality and cost effective completion of researches in the 21st century.

The Effect of ICT on Federal Radio Cooperation of Nigeria

[Abstract] [Full-Text PDF] [html]

Abstract: Information and Communication Technologies (ICT) developments have existed in Nigeria with a significant growth over the past decade. This paper looks at the role of emerging ICT on the general operations of Federal Radio Cooperation of Nigeria in achieving an objective of information decimation. This study shows that the ICT facilities have brought significant improvement to the FRCN service delivery which is important factor for growth and development in the society even though there are still some problems militating the use of ICT in the FRCN. The highest factor militating against the use of ICT is shortage of power supply followed by poor funding and lastly poor network facilities.

VITRO and IN VIVO Botanical Control of Rigidoporus microporus (SW.) Overeem of Para Rubber in Nigeria

[Abstract] [Full-Text PDF] [html]

Abstract: Rigidoporus microporus is the pathogen most feared by planters throughout the rubber tree growing regions of the world. The study was conducted to assess the effectiveness of botanical control of R. microporus on Para rubber in the rain forest zone of Nigeria. Twenty five plant species selected from sixteen families were screened for their fungicidal effects towards R. microporus, and five plant extracts exhibiting the highest mycelial inhibition were selected and assessed for concentration effects. Artificially inoculated rubber seedlings were treated with plant extracts. Significant differences were observed between the autoclaved and non-autoclaved extracts (p <0.05). Allium sativum exhibited the highest inhibitory effect among the 25 plant extracts tested. Autoclaved extract treatments exhibited higher inhibitory efficacy on R. microporus compared to the non-autoclaved extracts. Extract of A. sativum were effective at all concentration used both in the autoclaved and non-autoclaved extracts treatments, and their effects were not significantly different at both 25% and 50% extract concentration (P<0.05). The percentage of plant death and presence of rhizomorph recorded at two months after inoculation for early stage of infection were higher than that recorded at the termination of five months experimental period. Thonningia sanquinea treatment resulted with the lowest plant death rate two months after inoculation.

Domestic Biogas as a Driving Factor of Sustainable Development in Mugunga Sector of Gakenke District, Northern Rwanda

[Abstract] [Full-Text PDF[html]

Abstract This research focused on domestic biogas as a key driver of sustainable development in Rwanda, with special reference to Mugunga Sector of Gakenke District, Northern Rwanda. Data were collected from a sample of the heads of all households operating domestic biogas plants in the study area to whom a well structured questionnaire were administered in July 2013. Data were analyzed referring to the frequency counts, percentages. Besides, the NPV method was used to analyze the profitability of domestic biogas investment. The results indicated that domestic biogas contributes to the improvement of social conditions of households in the study area. It also has positive economic effects as well as contributes to the environmental protection. Socially, some respondents (80%) reported to use the domestic biogas for cooking everyday whereas some others (20%) say that domestic biogas is used rarely in cooking. The calculations of the net present value for domestic biogas investment without government subsidies (given the total investment cost of FRW 417,500 considers the present value of total revenue of FRW 459,078 and the present value of the total cost of FRW 523,099. The net present value without government subsidies is then -64 901. As a result, there is a loss from investing in domestic biogas plant without government subsidies. In contrast, the investment in domestic biogas with government subsidies is profitable as the corresponding net present value is 68,697. It is recommended to the households operating the domestic biogas plants to use it optimally and to the local authorities to sensitize farmers with enough cattle to invest in domestic biogas.
