Item Characterization of a mutant population of cocoyam (Xanthosoma sagittifolium L. Schott)(International Journal of Botany, 2006-02) Danquah, A.; Offei, S.K.; Blay, E.T.; Asare, E.; Danquah, E.Y.A mutant population of cocoyam (Xanthosoma sagittifolium L. Schott) developed through gamma irradiation of shoot tips of cocoyam was evaluated in two field experiments. In the first experiment, four putative mutants, fifty irradiated clones and four non-irradiated clones were evaluated for morpho-agronomic diversity. Progeny derived from minisetts were characterised in a second experiment to establish repeatability of the distinctive characters of the putative mutants. Yields were exceptionally low and this was attributed to poor environmental conditions. The mutants showed a distinctive yellow cormel apex and yellow interior cormel colour. Out of seventeen morphological traits studied in the second experiment, ten were monomorphic. These were growth habit, petiole attachment, petiole surface glaucous, leaf pubescence, leaf variegation, leaf surface glossy (shining), leaf margin, number of collecting vein, position of collecting vein and shape of petiole in cross-section. The seven polymorphic traits were petiole colour, colour of vein on leaf surface, leaf shape, leaf margin colour, leaf surface colour, leaf sinus denuding and lamina orientation. The main differences in the polymorphic characters were between the mutants on one side and the irradiated (non mutants) and non-irradiated clones on another side. It will be interesting to determine whether the mutants have desirable agronomic characters. © 2006 Asian Network for Scientific Information.Item Diversity, Distribution and Control of Aquatic Macrophytes of Southern Ghana with Particular Reference to the Alien Invasives(University of Ghana, 2015-07) Asare, E.; Ameka, G. K.; University of Ghana, College of Basic and Applied Sciences, School of Biological Sciences, Department of BotanyThe diversity and distribution of aquatic macrophytes particularly the invasives were studied in southern Ghana. The study area covered six regions in Ghana and these were: Greater Accra, Central, Ashanti, Eastern, Volta and Western. Forty-four sampling sites were visited and voucher specimens were collected and deposited in the Ghana Herbarium. Sixty-two aquatic macrophytes were encountered during the study which belonged to 48 genera and 30 families. Also, the invasive and non-invasive aquatic macrophytes that were encountered were also grouped according to the families they belonged. The Cyperaceae family emerged as the most dominant with 9 species. The criteria of IUCN (2004) were used in the identification of whether a particular species was an invasive or not. Based on this, the encountered aquatic macrophytes were separated into invasives and non-invasives. Eleven of the species were identified as invasives whereas the remaining fifty-two aquatic species were non-invasives. The life forms of the aquatic macrophytes were also determined. Forty one species (67%) were emergent, eleven species (17%) were free-floating, eight species (13%) were submerged and two species (3%) were floating-leaved. Distribution maps were drawn for the eleven invasive aquatic plants that were encountered. Pistia stratiotes was the most distributed invasive aquatic plant within the Southern part of Ghana with a total of seven distribution spots. A database was also created for all the sixty-two invasive and non- invasive species encountered. These comprised the scientific name and photograph of the species, synonym, common name, family, description, reproduction, habitat, distribution and uses. For each of the invasive aquatic macrophytes, the method of control was reviewed so as to make use of the best methods available that would help in their control/management.Item Evaluating the Impact of Interest Margin on the Profitability of Banks in Ghana: A Case Study of Fidelity Bank Ghana.(University of Ghana, 2019-05) Asare, E.The purpose of this current study was to examine the impact of interest margin on the profitability of banks in Ghana with the focus on Fidelity Bank Ghana. Purposive sampling technique was use to select Fidelity Bank for the study. Secondary data (Annual reports of Fidelity Bank Ghana Limited for 2013-2017) was analyzed. Data was analyzed with Pearson Correlation. The findings revealed that positive relationship exist between interest rate margin and bank profitability (ROA and ROE). The study concluded that for banks to make more profit there is the need to raise net interest margin through effective and efficient means of decreasing interest expense and increasing interest income. Also, banks need to put measures in place to ensure they grow their banks by increasing the size and also ensuring they get more customers to deposit with them.Item Food and nutrition assistance to HIV-infected and affected populations in Ghana: A situational analysis and stakeholder views(African Geographical Review, 2014-10) Laar, A.; El-Adas, A.; Amenyah, R.N.; Atuahene, K.; Asare, E.; Tenkorang, E.Y.; Laar, M.; Adjei, A.A.; Quakyi, I.Poor nutrition is a determinant of death particularly among persons living with HIV (PLHIV). This paper discusses the state of food and nutrition assistance to PLHIV in Ghana. A review of published articles and program reports was done and supported by in-depth interviews with key stakeholders. Data were qualitatively analyzed. A matrix highlighting problems that need to be addressed, possible attributable factors, strengths, and opportunities of existing actions metamorphosed from the analysis. Although stakeholders agree that adequate nutrition is critically important for PLHIV, food and nutrition interventions to PLHIV are inadequate. © 2014 The African Specialty Group of the Association of American Geographers.Item Natural resource governance, accountability and legitimising propensity: insights from Ghana’s oil and gas sector(Emerald Publishing Limited, 2021) Asare, E.; Burton, B.; Dunne, T.Purpose – This study explores Ghanaian views about accountability discharge by firms and government in the context of the nation’s newly discovered oil and gas resources. The research focusses on a range of issues relating to stakeholder interaction, communication flows and the impact of decision-making on Ghanaian lives, as perceived by individuals on the ground. Design/methodology/approach – The paper adapts elements of legitimacy theory to interpret the outcome of a series of semi-structured interviews with members of key accountee and accountor groups including citizens and representatives of the state and private firms in the oil and gas industry in Ghana. Findings – The results indicate that rather than attempting to effect substantive accountability discharge, Ghana’s government and oil and gas firms employ a wide range of legitimation strategies despite the apparently complete absence of the accountee power normally seen as driving the need for social contract repair. Research limitations/implications – The findings suggest that accountability discharge in Ghana is cursory at best, with several legitimising strategies in evidence. The representatives from state institutions appear to share some of the concerns, suggesting that the problems are entrenched and will require robust enforcement of a strengthened regulatory approach to effect meaningful change. Originality/value –This paper contributes to the literature on the discharge of institutional accountability by building on earlier conceptualisations of legitimacy theory to explore perceptions around a recent natural resource discovery. The analysis highlights grave concerns regarding the behaviour of state and corporate actors, one that runs counter to sub-Saharan African tradition.
