Journal: Journal of Sports Research

Export to    BibTeX   |   EndNote   |   RIS

Abstract
Tennis has used many different scoring systems throughout its history.  Researchers have been examining these scoring systems for over forty years.  While several intuitive themes have emerged, no systematic examination on how different scoring systems affect the stronger player’s probability of winning over a range of serving strengths has been done. This research study used simulation to examine the three most common scoring systems used in the United States and their effect on match win probability, total points played, and expected length of the match.  Moving from ad to no ad or 10-point scoring can result in a more than 3.5% and 5% respective decrease in the probability of the stronger player winning a match.  When applied to NCAA Division I team tennis, moving from ad to no ad can decrease the stronger team’s probability of winning by over 4%.  Changes between scoring systems are more pronounced at relatively weaker serving strengths.
Contribution/ Originality
This study formally quantifies, through a systematic design of experiment, how different scoring systems affect upset percentage, match length, and match duration in tennis, thus extending upon earlier work which touched upon these aspects in a less comprehensive and quantitative manner.

Journal: Journal of Tourism Management Research

Export to    BibTeX   |   EndNote   |   RIS

Abstract
The disabled customer market has become an increasingly important market in the hotel industry; however, the literature revealed a gap between what hotels provide and what needed by people with disability (PwD), which this study aims to bridge such a gap. The study employed a questionnaire comprising questions on 57 hotel attributes. The hotel attributes were divided into three groups: hotel employees, guest room, and public areas. A total of 200 questionnaires were distributed to a convenience sample of British PwD customers. Among the questionnaires returned, 126 were useable, representing a response rate of 63%. The analysis of variance test was employed to determine the presence of significant differences between four types of disabilities (i.e., hearing, sight, physical, and intellectual) in relation to the importance and performance of the 57 hotel attributes. Additionally, importance-performance analysis (IPA) was conducted using SPSS. The results showed some statistically-significant differences for two hotel attributes. Specifically, people with physical disabilities attached more importance to two hotel attributes, i.e., “Automated door openings should be provided”, and “All corridors should be suitable for wheelchair users.
Contribution/ Originality
This study contributes in the existing literature to investigate the requirements of British customers with disabilities in Egyptian hotels. The findings of the current study would be useful and helpful for hotels in making sure that the required facilities for disabled customers are covered in their plan.

Abstract
In this globalized era, travel and tourism has become an indispensable economic activity world over. It has the potential to strengthen the socio-economic foundation of a nation. It has the capability to disseminate the peace message across the globe. It is well-known for job creation, foreign exchange earnings, revenue and income generations, and developing socio-economic infrastructures. Thus, it is critical for unemployment reduction, poverty alleviation, inequality reduction, and bringing up balanced regional development. It is instrumental for achieving inclusive and sustainable growth of a nation like India and her States. It is with this backdrop, this paper is an attempt to assess the role of tourism in Odisha, an eastern State of India, as an engine of long-run economic growth. In recent years, tourism has grown considerably due to the availability of good infrastructure facilities, favorable government policies, improvement of existing tourist locations, development of new tourist destinations and strong growth of hotel and restaurant industry in the State. This is reflected in the growing number of both domestic and foreign tourists to the State. In a multivariate framework, the use of multiple regression model over the period spanning from 1990-91 to 2011-12 provides the evidence of the  positive contribution of the tourism sector to the economic growth of Odisha thereby justifying the role of tourism as an engine of long term growth of the State. Hence, the government of Odisha should formulate plans and policies such that tourism activities are promoted to lead a stable and sustainable growth of the State.
Contribution/ Originality

Examining Long Run Relationship between Household Debt and Household Savings in South Africa – An Error Correction Model and Granger Causality

Research Article
Author(s):
Journal: Quarterly Journal of Econometrics Research

Export to    BibTeX   |   EndNote   |   RIS

Abstract
Savings is vital to maintain and expand an economy’s capital structure and economic growth. Saving is an important component of economic growth model in that investments are created from savings. Investment allows an opportunity to improve technology and thereby increasing levels of productivity.  Increasing levels of productivity lead to increased real wages. The end result of increasing real wage is improvement of the welfare of the nation. Nevertheless, savings have been declining over the years, placing the South African economic development agenda in jeopardy. Since 1984, savings have deteriorated significantly, reaching a mere 15.3 percent of GDP in 2009 (SARB, 2010). The decline in savings at the beginning of the 1980s coincided with increased access to credit by households. Alongside these developments net wealth of the households increased relative to their disposable income (South African Reserve Bank (SARB), 2002). Mutyaba (2013) states that savings declined considerably during the last decade in South Africa. In 2006, for example, savings turned negative. In contrast, during the same year the debt increased to its highest level ever Mutyaba (2013). Clearly voluntary savings are becoming even more unaffordable by a number of households in South Africa, mainly amongst the low earners (Chiroro, 2010).This study uses Engle & Granger cointegration approach and granger causality to examine the link between debt and savings in South Africa.
Contribution/ Originality
This paper makes a contribution towards the household savings discourse in South Africa. The use of Engle and Granger cointegration approach to examine the link between household savings and household debt in this paper is one of the very few studies in this area in South Africa.

Abstract
This study seeks to identify key factors influencing the geographic settlement pattern of undocumented immigrants in the U.S., with a particular emphasis on the impact of economic freedom, and to extend the OLS findings in previous related studies. Indeed, this study adds to the literature in several ways. First, it provides current insights into the link between the settlement patterns of undocumented immigrants in the U.S. and economic freedom. Second, the study adopts a panel data-set and provides estimates using cross-section fixed-effects. Third, this study also endeavors to provide further insights into the impacts on the settlement patterns of undocumented immigrants of non-economic-freedom economic conditions, as well as the quality of life and spending on primary and secondary public education.  The various state fixed-effects estimates provided in the present study yield several conclusions. In particular, according to these estimations, the settlement pattern of undocumented immigrants in the U.S is inversely a function of colder climates, higher crime rates, higher population density, and a higher cost of living. In addition, the interstate distribution of undocumented immigrants to the U.S. is positively a function of the annual per pupil outlays on public primary and secondary education; it is also positively a function of the degree of economic freedom, the principal focus of this study.
Contribution/ Originality
This study contributes to the literature by providing contemporary insights into the factors influencing settlement patterns of undocumented immigrants in the U.S. using panel data. It is also one of the few studies to examine the influences of economic freedom and primary and secondary public school outlays.

The data source is cumulated from the Reserve Bank of India (RBI) Handbook of Statistics 2012. The empirical findings of the study show that there is a long-run equilibrium relationship exist among the variables. The result also suggest that money supply has a positive effect on GDP growth in India. The result of error correction indicates that correct and negative sign for Gross Domestic Product and exchange rate. The behavior of GDP implies there is no problem of adjustment in the long run in case of shocks in the short run. The VECM Granger causality confirms that unidirectional causality from GDP to inflation and exchange rate to inflation. The result also found that exchange rate Granger causes both GDP and money supply at 10 percent level of significance. The impulse response result shows that GDP has a positive response to money supply from the occurrence to the end of the period. Whereas the response of exchange rate to money supply negative in the whole lag period. The variance decomposition result explainss that no significant part of variance is caused by money supply. The result also reveals that cyclical variance of GDP caused by money supply, exchange rate, and inflation.

Journal: Review of Environment and Earth Sciences

Export to    BibTeX   |   EndNote   |   RIS

Abstract
This study analyzed spatial and temporal land use /land cover change in Jalingo Metropolis, Taraba State, north east Nigeria. This was carried out with the use of land sat images from 1990-2015. Satellite images were obtained from the United State Geological Survey (USGS) database online resources. The images were georeferenced and processed. Supervised image classification technique was employed. Ground truthing field survey was carried out to complement information about the types of land use and land-cover classes in the area. The change detection and change matrixes of the classified satellite images were analyzed using percentage to see the rate of change in a simple form. Land use maps were obtained through supervised classifications of satellite imageries and presented in Tables. The findings of the study show that Jalingo Metropolis has witnessed unprecedented spatial growth over the years. The town has grown from 6.01km2 in 1990 to 55.7km2 in 2005 and 101.16 in 2015. This growth was as a result of change in the status of the metropolis from Local Government headquarters to state capital which brought about the establishment of government ministries and agencies, with wide range of opportunities. Despite the existence of master plan, implementation has not been satisfactory for a number of reasons. This has resulted in proliferation of haphazard and uncontrolled development (including slums and squatters), environmental degradation, lack of basic amenities and transportation problems within and around the town. The study recommends the need to update the urban database of Jalingo town using GIS and Remote Sensing techniques to plan and monitor urban land use changes in the area.
Contribution/ Originality
This study is one of very few studies that maps urban sprawl in the study area. This helps to anticipate the likely danger of urban sprawl and the rate of urban expansion in the area.

Granulometric Study of the Lokoja Sandstone, Mid Niger Basin, Nigeria

Research Article
Author(s):
Journal: Review of Environment and Earth Sciences

Export to    BibTeX   |   EndNote   |   RIS

Abstract
Grain size studies of the Campanian-Maastrichtian Lokoja Formation have been investigated. The sand particles exhibit low sphericity which are angular to sub-angular. Histograms showed unimodal and bimodal trends and is predominantly asymmetrical with varying modal class, which may be due to variation in transporting medium energy. The graphic mean ranges from 0.1ф (coarse grained) to 1.35ф (medium grained) while the is average 0.81ф (coarse grained). The dominance of coarse grained particles and dearth of fine sands implies strong to moderate energy conditions during deposition. The standard deviation ranges from 0.08ф-0.60ф (very well sorted to moderately well sorted); average of 0.40ф (well sorted), which may be due to rapid back and forth movement of the depositing medium. The skewness ranges between -0.39 and 0.59 (strongly coarse skewed to strongly fine skewed), while the graphic kurtosis ranges between 0.77 and 2.5 indicating playtykurtic to very leptokurtic and this variation may be due to some of the deposits being sorted in high-energy environment elsewhere. A Bivariate plot (simple skewness vs. standard deviation) shows the samples plotting mainly in the river sand zone. Another plot of mean size vs. standard deviation also shows the samples appearing in the river sand zone; other granulometric parameters that discriminates between river channel deposits, overbank deposits and overbank-pool deposits shows that the Lokoja sandstones plotted in the river channel zone. Linear discriminant analyses signpost a shallow marine beach environment. From the Passega diagram, majority of the samples plotted outside the featured fields, only three samples plotted within the diagnostic parameter zone around the uniform suspension-SR zone.
Contribution/ Originality
The study contributes to the existing literature on the sandstone facies of the Lokoja Formation in the Mid Niger Basin based on granulometric parameters to establish the depositional environment of the sandstone and sedimentary process that occurred during deposition.

Abstract
Multi-junction solar cell layers containing CdTe/CdS/ZnO photovoltaic cells were created using SCAP 1D software using parameters based on the previous theoretical characterization to determine the significance effect on the optimization in terms of efficiency on the solar cell.  The simulation of the models were carried out by varying the band gap and thickness of the absorber layer and subsequently formulate model equation using regression analysis to determine the efficiency and fill factor at any given value.  Result shows that increase in the thickness of absorber layer increases fill factor, current density and open voltage from 83.74- 84.77, 26.26 -28.85mA/cm2, 0.71- 0.73, 15.51 -17.82% that ultimately resulted in a high efficiency of solar cell while increase in band-gap of the absorber layer reduces efficiency of the solar cell. Model equation gives errors ranges between 0.026 – 0.4 for thickness and efficiency, 0.0068 – 0.078 for thickness and fill factor and 0.003 – 0.2 for band gap and efficiency. The study shows that large thickness of absorber layer and low band gap favor the optimization and model equations can be used to estimate/forecast the efficiency and fill factor within the limit of the variable parameters and this offers better direction for laboratory experiment.
Contribution/ Originality
This study contributes in the existing literature that energy is an uncompromised essential ingredient for socio-economic development and economic growth. We have created multi-junction solar cell layers containing CdTe/Cds/ZnO photovoltaic cells using the common SCAP ID software with varying parameters for characterization. Simulations were achieved by varying band gap and thickness of the absorber layer and thereby formulating developing model equations. Model equations were obtained using regression analysis. Yielded model equations gave minimal errors that was adequate for the simulations resulting in higher efficiency.
