4.  DETAILS OF RECENT RESEARCH WORKS UNDERTAKEN

Since my appointment as a Demonstrator, I have undertaken a total of 6 research works. Details of the research undertaken since 2017 are as follows

A.  2018: Effect of Climate Conditions on Gold Production in Ghana

This study examined the effect some climate factors on gold production in Ghana as the change in climate conditions and its catastrophic effect on mining activities have become a source of worry for mining industries. In order to better understand the effect of these climate factors on gold production, regression with ARIMA errors technique was employed after its appropriateness had been tested. The model was then compared in terms of prediction accuracy which resulted a MAPE of 9.78%. It was concluded that, gold production in Ghana is positively related to Temperature whilst negatively to Rainfall and Precipitate. It was recommended that mine operators in Ghana could base on this analysis to optimise their production planning and scheduling.

B.  2018: Technical and Vocational Education Training (TVET) in Ghana’s Industrial Development

This study presents a discussion on the importance of Technical and Vocational Education and Training (TVET) in the industrial development of Ghana. To itemise the position of TVET as an important player in Ghana’s industrial development, data from different sources were critically analysed and discussed. Upon comparing the TVET enrolment of some developed countries and that of Ghana, it was realised the TVET has a great impact on the overall development of a country’s industry. Some challenges facing the TVET system in Ghana were identified and discussed. Logical suggestions were made on how to enhance the operation of TVET in Ghana in order to make it attractive for more youths to get enrolled on it.  Also, guidelines were given to create job opportunities that would absorb TVET graduates.

C.  2018: Comparative Study of Mathematical Models for Ghana’s Gold Production       

This study made use of Sigmoid functions to approximate the cumulative gold production in Ghana. The functions examined were the Logistic, Gompertz, Gaussian, Probit and the Hill, which were then used to predict the future. Although all the five approximated models gave a good estimation of the reality, the Gompertz function was identified to give the best approximation of the observed trend of gold production in Ghana. The model suggested that gold production could rise up in the future to a level of 7040813 Oz. It also showed that industrial scale production of gold should be possible even after the year 2050 provided the current upward trend of gold production in Ghana continues.

D.  2018: Analysis of Carbon Dioxide Emissions in Ghana

This study analysed the total emissions of Carbon Dioxide (CO2) in Ghana since the alarming rate of CO2 emission into the atmosphere and its catastrophic effect on the environment have become a source of worry for many nations and therefore needs due attention. Multiple Linear Regression was applied on all the sectors contributing to the overall CO2 emission which caused multicollinearity problems. In order to eliminate multicollinearity problems and better understand the interrelationships among these sectors, Factor Analysis was employed after its appropriateness on the data had been tested. The Autoregressive Integrated Moving Average (ARIMA) technique was then used to develop a model to forecast the total CO2 emissions in Ghana. It was concluded that the Transport sector, the Manufacturing and Construction sector, Electricity and Heat sector were the predominant sectors that significantly contributed to the overall CO2 emission in the atmosphere.

E.  2018: Comparative Study of Mathematical Models for Population Growth in Ghana Prisons

The study examined the population growth in the Ghana Prisons based on three growth models. The models examined were the Logistic, Gompertz and the Gaussian functions which were then used to predict into the future. Although all the approximated models gave a good estimation of the population of prisoners in Ghana, the Gompertz function was adjudged to give the best approximation of the observed trend. The model was selected based on its high proportion of variance explained (R2 = 0.9468) as well as having the least value in terms of error (RMSE) and information loss (AIC). The model suggested that the population of prisoners in Ghana could increase to about 14558 from the current (2017) observed value of 14457.

F.  2017: Parsimonious Model for Predicting Cocoa Production in Ghana

This study examined the combined effect of socio-economic and climatic variables on Ghana’s cocoa production. First, only Multiple Regression Analysis was applied to all the variables affecting cocoa production which caused multicollinearity problems. In order to eliminate multicollinearity problems and perform a reliable regression, Factor Analysis was employed after its appropriateness on the data had been tested. Thus, the problems were removed by using factor scores, summated scales and surrogate variables for the regression analysis. Also, the most significant determinants affecting cocoa production in Ghana were identified through which various parsimonious models were developed using regression models with ARIMA errors technique. The model parameters had least multicollinearity values that best describe and predict Ghana’s cocoa production. The parsimonious models were then compared in terms of prediction accuracy. It was concluded that the factor scores model (with an interaction term) was concluded to give better interpretation and good estimates of Ghana’s cocoa production as compared to the remaining models.
