                <text>This study was conducted to ascertain records management practices at the Ghana Communications Technology University (formerly Ghana Technology University College) a mid-sized Ghanaian public university located in Accra. All the staff at the Admissions and Records departments participated in the study. This comprised two (2) heads of department and seven (7) senior staff from both departments. The face-to-face interviews were employed as a data collection instrument for this study. The findings indicated that the University has neither a policy to regulate the management of students' records nor a professional archivist to manage records. However, the head of the Records office was given a three-day training on the assumption of office. It was revealed that the head of admissions, as well as all the staff of the two departments, had never been given any training. There were some challenges impeding records management in the Admissions and Records offices–among them are; lack of adequate staff, inadequate storage equipment, lack of periodic training, lack of policy to guide records management and inability of students to furnish the Admission office with the needed information. It was recommended that the University should employ a professional archivist to manage student records, provide adequate storage facilities, organise periodic training for staff as well promulgate a policy to guide records management in the Admissions and Records offices.</text>

                <text>In the present knowledge economy, individuals, particularly working adults, need to continuously acquire purposeful knowledge and skills so they can better contribute towards addressing society’s ever-changing developmental challenges. In the developing world however, few opportunities exist for working adults to acquire such new learning experiences through the formal education sector, and this makes it imperative for organizations to develop non-formal education and training programs to help address this need. With the proliferation of Information and Communication Technologies (ICTs) worldwide, this article recommends the adoption of Collaborative Online Learning (COL) by non-formal learning organizations as a means of helping address the education and training needs of working adults. The article thus provides an overview of COL, and then draws on the research literature on relevant theories to …</text>

                <text>Transaction log analysis (TLA), content analysis, and grounded theory procedures were used to explore the use of an institutional digital repository and social networking website by the academic community of a graduate school of education in the northeastern United States. Three successive years of usage records were gathered and analyzed to determine: (a) the numbers and categories of persons signing up to use the repository during each school semester, (b) the type of content being archived and its rate of growth, and (c) the possible influence of the repository on collaborative, online and open access scholarship within the institution. Findings show a steady increase in the usage of the repository for archiving and sharing digital resources, and an item-tagging scheme that suggests user preference of the resource as a platform for enhancing professional rather than personal interests.

                <text>The primary objective of this paper was to investigates the use and benefits of simulation for basic instrumentation and process control education. This simulation approach provide valuable solution by giving clear insights into complex systems. A graphic computer simulation program, for controlling and neutralising acidic wastewater has been developed. The simulator (pH-neutraliser) was developed using Microsoft Visual Basic Programming language and process control principles. The program was designed to provide an intuitive interface by correcting and adjusting the acidic pH of wastewater to 7 (neutral pH) before discharge into the environment. The acidic wastewater can be neutralised by alkali reagents like caustic soda or lime. The simulator was designed to operate in both manual and automatic modes during the neutralisation process. In the manual mode, the pH-neutraliser alerts an operator by sounding an alarm and suggests the percentage by which the alkali reagent valve should be opened to add required amount to bring the pH of the wastewater to 7. This is done when the measured value from the pH sensor and transmitter is not equal to the desired value. In the automatic mode, the neutraliser is expected to automatically open the alkali reagent valve to the required percentage to add the needed amount of alkali to make the pH of wastewater neutral. The pH neutralisation automation of wastewater can be achieved with the aid of pH analytical sensor and transmitter, signals, controller and feedback control mechanism.</text>

                <text>In this study, we explore both univariate and multivariate aspects of time series analysis. In the univariate aspect, we evaluated the predictive performance of three widely used univariate time series methods in forecasting the electricity consumption in Ghana during the 1980–2011 periods. The three univariate time series approaches are autoregressive integrated moving average (ARIMA), autoregressive fractional integrated moving average (ARFIMA) and exponential smoothing. In each approach, we examined competing models and the “best” model according to the minimum information criterion and diagnostic checking was selected. The forecast accuracy measure (ie; mean absolute forecast error, MAFE) was computed for each “best” model in the three different approaches. The empirical results revealed that the MAFE for ARIMA, ARFIMA and exponential smoothing were 31.3%, 9.4% and 41.6% respectively. Thus, the comparative analysis of the forecast performance of these methods clearly concluded that the ARFIMA method gives better forecast in predicting electricity consumption in Ghana. And, in the multivariate aspect, we examined whether GDP, export, import and population influences electricity consumption. The results revealed a feedback causality between electricity consumption and economic growth. Again, we established that there exists an uni-directional influence of import, export, population towards electricity consumption. The “best” model of the univariate approach is ARFIMA (2, 0.31, 1) with MAFE of 9.4% while the “best” model for the multivariate approach is vector error correction model VECM (3) with MAFE of 1.5 …</text>
