Causes and Effects of Frequent and Unannounced Electricity Blackouts on the Operations of Micro and Small Scale Industries in Kumasi
Imoro Braimah,Owusu Amponsah
Journal of Sustainable Development , 2012, DOI: 10.5539/jsd.v5n2p17
Abstract: The aim of this paper was to examine the causes and effects of the frequent and unannounced electricity blackouts on the operations of micro and small scale industries (MSI) in Kumasi, Ghana. Data from a sample of 320 MSI selected from three industrial clusters in the Kumasi metropolis, revealed that the frequent and unannounced blackouts have caused a deficit of about 5.3% in the quantity of electricity they required for continuous operations. The blackout hours were estimated to last for an average of 10.3 hours per month. As a consequence of the blackouts, about 44% of the MSI spent this duration in redundancy because of lack of alternative sources of electricity but maintained the same labour cost. The remaining 56% of the MSI obtained power from alternative sources which required an average of GH¢15.5 per month to run. The paper concludes that uninterrupted electricity supply is vital for the effectiveness of the MSI.
Commercial Charcoal Production and Sustainable Community Development of the Upper West Region, Ghana
Kwasi Osei Agyeman,Owusu Amponsah,Imoro Braimah,Stephen Lurumuah
Journal of Sustainable Development , 2012, DOI: 10.5539/jsd.v5n4p149
Abstract: Policy discussions have suggested a complete ban on charcoal production and the introduction of substitutes to meet the energy needs of the growing number of consumers. These discussions are fuelled by the effects of the charcoal industry’s activitities on the environment. On the contrary, the authors of this paper highlight the need to sustain the charcoal industry in the Upper West Region of Ghana. This conclusion was arrived at through an analysis of the charcoal industry’s role in economic development of some communities in the Upper West Region. Data gathered from 500 commercial charcoal producers and 50 charcoal buyers indicated that commercial charcoal production is a major source of livelihood. While charcoal producers earned monthly incomes of about GH¢200, the buyers’ earned between GH¢82 - 2 343 per month. Despite its economic importance, the industry’s environmental problems are enormous. These were attributed to the extraction of raw materials, mainly live trees, from the natural forest without replacement. The authors concluded that the way forward towards sustainable economic development through charcoal production lies in the adoption of efficient charcoal production technologies.
Dimensions Of Basic School Dropouts In Rural Ghana: The Case Of Asutifi District
B Imoro
Journal of Science and Technology (Ghana) , 2009,
Abstract: The objective of this paper was to investigate the various dimensions of basic school dropouts in rural Ghana using the Asutifi district as a case study. The analysis of data (both quantitative and qualitative) gathered from several stakeholders of basic education in the district, revealed that the causes of school dropout were rather complex. Poor educational outcomes in terms of per-formance of candidates in the final examinations of the basic level as a result of the poor quality of teaching and learning in the rural environment was directly linked to the high rate of drop-out. Although some stakeholders claimed that poverty was the main cause of school dropout, the significance of the loss of confidence in the educational system cannot be overemphasised. The policy implication is that quality consideration in the basic education delivery should now be the priority in order to regain the confidence of parents and their wards in the educational system in general so that enrolments and retention of children in school could be enhanced.
Challenges of the 21st Century Ghanaian Universities
I Braimah
Journal of Science and Technology (Ghana) , 2004,
Abstract: After going through a period of higher educational reforms, Ghanaian public Universities are now being challenged to determine their future survival. Understanding the challenges facing the Universities is one step forward in the development of the right strategic decisions. These challenges, which include Revenue diversification and Institutional Autonomy, Information and Communication Technology, Changing Student Mix, Quality Enhancement and Relevance, Administrative and Management Structures and Processes, Equity and Access to Higher Education and Networking and Partnership Development, were analysed from the perspectives of the KNUST. The analysis revealed policy options that could be formulated to address these challenges for the sustainability of Universities in the 21st Century Ghana. The need for institutional transformation to be able to confront and manage the challenges has been recognised. It is therefore recommended that Ghanaian Universities could task the relevant units within the various institutions to conduct studies that would enable them monitor and advise management on measures to tackle the various challenges.

Construction Delay Analysis Techniques—A Review of Application Issues and Improvement Needs

Buildings , 2013, DOI: 10.3390/buildings3030506
Abstract: The time for performance of a project is usually of the essence to the employer and the contractor. This has made it quite imperative for contracting parties to analyse project delays for purposes of making right decisions on potential time and/or cost compensation claims. Over the years, existing delay analysis techniques (DATs) for aiding this decision-making have been helpful but have not succeeded in curbing the high incidence of disputes associated with delay claims resolutions. A major source of the disputes lies with the limitations and capabilities of the techniques in their practical use. Developing a good knowledge of these aspects of the techniques is of paramount importance in understanding the real problematic issues involved and their improvement needs. This paper seeks to develop such knowledge and understanding (as part of a wider research work) via: an evaluation of the most common DATs based on a case study, a review of the key relevant issues often not addressed by the techniques, and the necessary improvements needs. The evaluation confirmed that the various techniques yield different analysis results for the same delay claims scenario, mainly due to their unique application procedures. The issues that are often ignored in the analysis but would also affect delay analysis results are: functionality of the programming software employed for the analysis, resource loading and levelling requirements, resolving concurrent delays, and delay-pacing strategy. Improvement needs by way of incorporating these issues in the analysis and focusing on them in future research work are the key recommendations of the study.
Approaches to Delay Claims Assessment Employed in the UK Construction Industry

Buildings , 2013, DOI: 10.3390/buildings3030598
Abstract: Construction project delays emanates from multiplicity of different sources of risk events. This, combined with high uncertainty in cause-effect relationships between the events and their impacts on project completion dates, have created immense difficulties in apportioning project delay responsibilities amongst contracting parties. This challenge is now dealt with by various delay analysis approaches, yet delay claims settlement continues to be a troublesome undertaking. Empirical research on these approaches as to their application in practice is limited, although such studies provide important reference sources to practitioners and researchers. As a contribution to addressing this gap, this paper reports on practitioners’ views on the approaches based on a UK nation-wide questionnaire survey of construction and consulting companies. The key findings of the study include: (1) delay claims are often resolved late and not close in time of occurrence of the delay events, creating more difficulties; (2) simplistic delay analysis approaches are widely used in practice and form the basis of successful claim resolutions, although they have major weaknesses; (3) the sophisticated approaches, although are more robust, are generally not popular in practice. To promote the use of these reliable approaches and help reduce or avoid disputes amongst claims parties, programming and record keeping practices must be improved as they do not facilitate the use of the approaches.
Water and sanitation committees for sustainable service delivery in Ghana: the case of Nanumba north district, Northern region, Ghana
I Braimah, EM Jagri
Journal of Science and Technology (Ghana) , 2007,
Abstract: The achievement of the targets in terms of water and sanitation coverage in Ghana depends to a large extent on the establishment of institutions like Water and Sanitation Committees (WATSAN) for effective operation and maintenance of the water and sanitation facilities. This paper is based on the assessment of WATSAN in the Nanumba North District in the Northern Region of Ghana, where considerable investment in the sector has been made. The study established, among others, that the operations of the WATSAN were limited in terms of scope and effectiveness mainly due to their limited financial strength. It revealed that the institutional environment within which WATSAN operate as well as their modus operandi determined the communities' response to the maintenance and service delivery challenges. In view of these it is recommended that the institutional framework and composition of WATSAN be strengthened and scaled upwards to the District Assembly and the members should be financially rewarded from the proceeds of user fees so that they can effectively ensure sustainable water and sanitation services delivery. These measures are in line with the principles of the new public management strategies for public service delivery. Journal of Science and Technology(Ghana) Vol. 27 (1) 2007: pp. 90-101

Abstract: Several studies have evolved to deal with the determinants of stock market volatility. However, there exists a gap in literature with regards to the interrelation among the broad categories of factors that trigger stock market reaction namely company fundaments, technical factors and market sentiments. This paper provides a holistic and comprehensive theoretical review of drivers of stock markets’ reaction as well as designs an interrelated conceptual framework of the factors that influence investors’ decision making to fill the gap in literature. Brexit is presented as a case study to illustrate how investors and stock markets are affected by new events or information. This study will reveal some of the global staggering effects of Brexit at the end of trading on June 24, 2016 in areas such as currencies, stock markets, banks, commodities, bonds, automakers and homebuilders as well as hedge fund. Barely 24 hours after the results of Brexit were declared; global stock markets lost about $2 trillion in value. The British pound plunged to almost $1.33, its lowest level in over 30 years against the US dollar and gold proved to be one of the few safe havens for investors on that day. In order for investors to insulate themselves against loses from Black Swans events, the conclusion of this study recommends some protective mechanisms for investors which include avoidance of overexposure and stockpiling of cash.
Basic school dropout in Ghana: a case study of the Amansie West district
I Braimah, E Oduro-Ofori
Journal of Science and Technology (Ghana) , 2005,
Abstract: In view of the increasing cost of education the persistent phenomenon of school dropout has become a constant worry to all stakeholders. The focus of this paper was to assess the trend of basic school dropout in Amansie West, a predominantly rural district in Ghana and to further determine the main causes and policy implications of the phenomenon in the district. Analysis of the data revealed a downward trend in the dropout rates. At the primary school level, the dropout rate reduced from 5.4 percent in 1998/99 to 4.5 percent in the year 2000/01. At the Junior Secondary School (JSS) level, the dropout rate also reduced from 9.7 percent in 1998/99 to 6.7 percent in 2000/01. This trend was attributed to the diversification of the income sources of parents, which enabled them to earn more income to take care of their wards in school. Further analysis of data gathered revealed that about 45.4% of the parents of school dropouts in the district were extremely poor with annual incomes less than ¢600,000. The views of all stakeholders of education in the district confirmed that the causes of basic school dropout were mainly poverty related. In view of the strong inverse relationship between rates of school dropout and income levels it is recommended that pro-poor programmes be initiated and implemented in order to increase enrolment and retention of children in school for the ultimate benefits of public investment in education to be derived.

Alexandra Lutz, Samuel Diarra, W. Braimah Apambire, James M. Thomas, Jarvis Ayamsegna
Journal of Water Resource and Protection (JWARP) , 2013, DOI: 10.4236/jwarp.2013.58A002

The purpose of this study was to evaluate parameters of drinking water quality from hand-pumps in Ghana, Mali, and Niger, evaluate possible sources of parameters, and provide an overview of potential health effects in the population. Concentrations of 22 parameters in 3337 groundwater samples were analyzed and compared with World Health Organization drinking water guidelines. In general, F, Mn, and Al had relatively larger and more common rates of occurrence, though there was by country. For F, there were reports of skeletal fluorosis in Niger and dental fluorosis in Ghana. For Mn and Al it was difficult to assess health effects due to scarce information.
