One dimension of user-involvement in the design process is the management of user preferences. Managing user preferences, as a way towards optimizing value in the design process, could sometimes involve making tradeoffs among competing design options. The focus of this research is to explore the possibility of applying the choosing by advantages (CBA) decision system to manage user preferences in the design process, especially at the conceptual design stage. The CBA decision system was therefore applied to choose between two conceptual design options in relation to the expansion of an operating theater building at the Holy Family Hospital in Techiman, Ghana. A workshop involving the design team, user-group, and management of the hospital was organized to decide on the options using the CBA approach. The findings from this study illustrate the CBA decision aid as a transparent and participative decision system, capable of creating and sustaining a collaborative atmosphere of trust and respect in the involvement of users to make design choices. The observed attributes of the CBA decision system makes it worthwhile to incorporate it in a user-involvement framework for design process. © 2015 American Society of Civil Engineers.

In this paper we demonstrate the importance of non-economic values to community- based conservation by presenting findings from research into Kunlog Community Resource Management Area (CREMA) in northern Ghana. One of the central motivations for creating the CREMA was to reinforce a traditional taboo on bushbuck, and while some respondents mentioned the possibility of eventually attracting tourists, the primary desire behind the CREMA is to protect bushbuck and other wildlife for future generations. Several respondents emphasised wanting children and grandchildren to be able to grow up seeing the wildlife. Material benefits should not be the sole focus of those involved in promoting and legislating frameworks for community-based conservation - frameworks such as Ghana's CREMA policy. Government frameworks for the creation, registration and regulation of conservation initiatives should be flexible and able to accommodate diverse community-based conservation initiatives driven from a variety of mixes of motivations, including motivations deriving from non-material values. © 2013 The White Horse Press.

One of the quality control measures in the construction industry in Ghana is the statutory requirement for the acquisition of permits before the commencement of construction work. The acquisition of these permits, among others, ensures quality of building construction products and less impact on the environment. The process of obtaining these permits has however been observed to be associated with steps that affect the flow of pre-construction activities leading to delays, and possibly cost overruns and decreased value of building construction products. The paper examines the processes involved in obtaining building construction permits and how that impacts flow of activities at the pre-construction stage. The study focused on the Sunyani Municipality, an emerging urban area in Ghana. Permit issuing authorities like the Municipal Assembly, the Environmental Protection Agency and the National Fire Service were contacted for data on permit acquisition processes and requirements. Developers and consultants who have been involved in obtaining permits from these authorities were also interviewed. The study points to the acquisition of permits as one of the obstacles in ensuring continuous workflow in the building construction project delivery process, mainly due to lack of integration of process steps as well as delays in processing and issuing the permits.

Mine rock waste, which is the rock material removed in order to access and mine ore, is free from gold processing chemical contaminants but presents a significant environmental challenge owing to the large volumes involved. One way of mitigating the environmental and safety challenges posed by the large volume of mine rock waste stockpiled in mining communities is to find uses of this material as a substitute for rock aggregates in construction. This article reports on a study conducted to evaluate the engineering properties of such a mine deposit to determine its suitability for use as road pavement material. Samples of mine rock waste, derived from the granitic and granodioritic intrusive units overlying the gold-bearing metavolcanic rock and volcano-clastic sediments of a gold mining area in Ghana, were obtained from three mine rock waste disposal facilities and subjected to a battery of laboratory tests to determine their physical, mechanical, geotechnical, geometrical and durability properties. The overall conclusion was that the mine rock waste met all the requirements of the Ghana Ministry of Transportation specification for use as aggregates for crushed rock subbase, base and surface dressing chippings for road pavements. The recommendation is to process it into the required sizes for the various applications. © The Author(s) 2015.

This paper seeks to determine the nutritional composition of the seed of Icacina senegalensis (false yam), a plant found in the Yunyoo community in the northern region of Ghana. The seed in both its unprocessed and processed forms were analyzed for their proximate and mineral compositions. This was done to determine the nutrient content and the effect of processing on the nutrient composition. The results showed a general decline in the mineral concentration from the unprocessed to the processed forms of the seed. However, for the proximate composition, there was an increment in the concentration of moisture, fibre and carbohydrate while the rest of the compositions (crude protein, fat, ash as well energy) decreased in the processed seeds. There was significant difference between the nutrient content of the unprocessed and processed seeds (P<0.05) and hence, it was concluded that the mode of processing had the effect of reducing the nutritional value of Icacina senegalensis seed. © Asian Network for Scientific Information, 2013.

Corporate social responsibility (CSR) and its impacts on financial performance has been studied exhaustively, however proponents reports differing findings. A number of studies have shown that there exist a significantly positive correlation between research and development (R&D) and profitability. Between the period 2009 and 2013, we analyzed 500 Ghanaian cases in which companies' integrate R&D investments as one of their business sustainable development strategies for feasible advancement; they additionally recognize their altruistic "give-away" as commitments to CSR. In view of hypothetical affirmations and observational confirmation in this study, we recognized a positive relationship between CSR and financial performance. © 2016 Trans Tech Publications, Switzerland.

The study was carried to investigate the extent of adherence of exclusive breast-feeding among student mothers in the University of Cape Coast. The research assessed perceptions of student mothers in this regard. Stratified, proportionate sampling method was used to select student mothers who were lactating or had weaned their babies in the past 3-6 months of this study. Questionnaires were administered to collect data from the respondents. Frequency distribution tables and discussions were used to sum up the data. The study revealed that all the respondents (100%) were aware of the six months exclusive breast feeding but only four percent of the respondents were able to breast-feed exclusively. The study recommend that, there should be a conscious effort by women's groups and policy makers to ensure that time table schedules in tertiary institutions will enable student lactating mothers to breast-feed their babies for the benefit of mothers and babies concerned. © Asian Network for Scientific Information, 2014.

Access to reliable electricity is important in increasing the living standards of households and promoting sustainable development. However, Ghanaian households have had to grapple with frequent power outages and poor quality electricity services in recent times. This study examines the factors influencing households' willingness to pay for reliable electricity services in Ghana. Using data collected from 950 households in the Cape Coast Metropolitan Area and the Tobit regression technique, it was revealed that monthly income, prior notice on power outages, business ownership, separate meter ownership, household size and education significantly affect willingness to pay for reliable electricity services. On the average, households were prepared to pay 44 percent [GH¢6.80 (US$3.42)] more, relative to the mean monthly electricity bill in the sample, to improve electricity services. It is envisaged that the findings would be used by policy makers and utility companies to make electricity generation and distribution more sustainable and efficient. © 2016 Elsevier Ltd.

Waste associated with building design is one of the causes of the high cost and slow progress of construction projects in Ghana. Proper management of waste at the design stage is therefore a fundamental step towards achieving speedy delivery of building projects at minimum cost. This paper seeks to examine the level of awareness of sources of waste and the application of waste reduction tools in the building design process by Ghanaian consultancy firms. Data on the design activities of the firms were collected by distributing questionnaires to consultants, while contractors and clients were interviewed. Involvement in various building design processes was also used to obtain data for the study. Results revealed a generally low recognition of sources of waste in the building design process and little awareness of waste reduction tools such as design structure matrix, batch size reduction and set-based design. It was also found that inadequate familiarity of the firms with lean thinking was among a number of limitations to the application of waste reduction tools in Ghana. This suggests that there is a need to improve the awareness of lean design management in both education and practice in Ghana. © 2011 Earthscan ISSN.
