Background: Occupational risk management is known as a catalyst in generating superior returns for all stakeholders on a sustainable basis. A number of companies in Ghana implemented health and safety measures adopted from international companies to ensure the safety of their employees. However, there exist great threats to employees' safety in these companies. The purpose of this paper is to investigate the level of compliance of Occupational Health and Safety management systems and standards set by international and local legislation in power producing companies in Ghana. Methods: The methodology is conducted by administering questionnaires and in-depth interviews as measuring instruments. A random sampling technique was applied to 60 respondents; only 50 respondents returned their responses. The questionnaire was developed from a literature review and contained questions and items relevant to the initial research problem. A factor analysis was also carried out to investigate the influence of some variables on safety in general. Results: Results showed that the significant factors that influence the safety of employees at the hydroelectric power plant stations are: lack of training and supervision, non-observance of safe work procedures, lack of management commitment, and lack of periodical check on machine operations. The study pointed out the safety loopholes and therefore helped improve the health and safety measures of employees in the selected company by providing effective recommendations. Conclusion: The implementation of the proposed recommendations in this paper, would lead to the prevention of work-related injuries and illnesses of employees as well as property damage and incidents in hydroelectric power plants. The recommendations may equally be considered as benchmark for the Safety and Health Management System with international standards. © 2016 The Authors.

For a sustainable economic development, premium fuel forecasting is becoming increasingly relevant to policy makers and consumers. The current paper develops a structural econometric model of premium fuel using the autoregressive integrated moving average (ARIMA) to analyse and forecast premium demand. The results show that the ARIMA models (1, 1, 0); (0, 1, 1) and (1, 1, 1) are the appropriate identified order. The estimated models included a constant term. All the coefficients of the variables in the model except the constant term were significant. The diagnostic checking of the estimated model shows ARIMA (1, 1, 1) as the best fitted model since all the series were randomly distributed. The data for the forecast covers the period 2000:01 to 2011:12. The results indicated that the forecasted values fitted the actual consumption of the energy variables since the forecasted values insignificantly underestimate the actual consumption and thus indicate consistency of the results. The evaluation statistics indicate that the estimated models are suitable for forecasting. The model developed in the work is helpful to the energy sector and policy makers in making energy related decisions and investigating the changes in premium demand. © 2015, Econjournals.

This paper describes the i2CAP project for senior high school students in Ghana. The project promotes and demystifies computer programming through programming contests. It is run in two distinct divisions: inter-schools programming contests and the National Olympiad in Informatics (in preparation towards IOI participation). This project has developed the algorithmic thinking and computer programming capacity of about 10,000 students and 303 ICT teachers from 257 senior high schools throughout the Ghana. This paper describes selection, training and organization of the project as well as the challenges and successes of running a fairly balanced programming contest among digital divided senior high schools in Ghana. © 2012 Vilnius University.

This study establishes the use of software to provide efficiency for turnkey electrification projects in Ghana. A correlation design method is employed to a sample of thirty one stakeholders in the power distribution sector in Ghana, and it reveals that there is negative perceived ease of use of software for managements of electrical turnkey projects. T-Test conducted on usage of PM software indicated that statistically there is no usage of PM software and those projects are manually managed in Ghana. © 2014 IEEE.

Ghana discovered commercial oil and gas in 2007, and, subsequently, commenced production in the last quarter of 2010. In the light of the potential economic boost that will accompany petroleum production, its discovery was welcome news for Ghanaians. However, oil exploration and production involve several activities that can have detrimental impacts on the ecosystem. In this paper, the potential sources of pollution in the upstream sector of the oil and gas industry and their effects on the environment are discussed. Also discussed are existing national environmental management legislations in the extractive industry, and the implementation and enforcement challenges these regulations face. Strategies to curtail the effects of oil and gas development on the ecosystem are also put forward. These include the need for government to formulate petroleum industry-specific environmental protection guidelines and appropriate regulatory frameworks. Such regulations in managing the environment should employ an integrated approach involving (i) prescription of environmental codes and setting of standards by government to be met by operators, and (ii) the need for oil companies to develop environmental management system (EMS) to ensure that they operate within the environmental standards for the industry. Administrative and institutional restructuring and reforms, as well as the provision of the necessary financial and human resources for the various environmental agencies, should be encouraged to ensure effective implementation, enforcement and monitoring.
