Determinants of Mobile Banking Adoption in the Ghanaian Banking Industry: A Case of Access Bank Ghana Limited  [PDF]
Agbemabiese George Cudjoe, Patrick Amfo Anim, Joseph Gerald Nii Tetteh Nyanyofio
Journal of Computer and Communications (JCC) , 2015, DOI: 10.4236/jcc.2015.32001
Abstract: The study examined the determinant of mobile banking adoption among bank customers in Ghana, with specific emphasis on Access Bank. In line with literature, the study applies theoretical frameworks which have been developed from existing literatures on innovation and adoption to collect responses from one hundred and fifty (150) sampled customers of Access Bank in order to investigate the determinants of mobile banking adoption in the Ghanaian banking industry. The results from the study revealed that, each factor measured had some level of significant effect on consumer intention to adopt and use mobile banking services provided by Access Bank. Additionally, the study unveiled that, perceived credibility and perceived financial cost were the major setback with regards to customers adoption of mobile banking services provided by Access Bank, and as a result of this, Ghanaians have formed a negative behavioural pattern towards mobile banking. In addition, the findings showed that, perceived credibility and perceived financial cost have a stronger effect on consumer intention to adopt and use mobile banking service than perceived usefulness and perceived ease of use. It was, therefore, recommended that banks in Ghana should create more awareness through personal interaction with customers, develop quality initiatives in order to build customer’s confidence. Equally, banks should also review the cost of their mobile banking service.
Differential Role of Two-Component Regulatory Systems (phoPQ and pmrAB) in Polymyxin B Susceptibility of Pseudomonas aeruginosa  [PDF]
Daniel Owusu-Anim, Dong H. Kwon
Advances in Microbiology (AiM) , 2012, DOI: 10.4236/aim.2012.21005
Abstract: Polymyxins are often considered as a last resort to treat multidrug resistant P. aeruginosa but polymyxin resistance has been increasingly reported worldwide in clinical isolates. Polymyxin resistance in P. aeruginosa is known to be associated with alterations in either PhoQ or PmrB. In this study, mutant strains of P. aeruginosa carrying amino acid substitution, a single and/or dual inactivation of PhoQ and PmrB were constructed to further understand the roles of PhoQ and PmrB in polymyxin susceptibility. Polymyxin B resistance was caused by both inactivation and/or amino acid substitutions in PhoQ but by only amino acid substitutions of PmrB. Alterations of both PhoQ and PmrB resulted in higher levels of polymyxin B resistance than alteration of either PhoQ or PmrB alone. These results were confirmed by time-killing assays suggesting that high-level polymyxin resistance in P. aeruginosa is caused by alterations of both PhoQ and PmrB.
Steaming between the Islands: Nineteenth-Century Maritime Networks and the Caribbean Archipelago
Anyaa Anim-Addo
Island Studies Journal , 2013,
Abstract: Recent scholarship, particularly in “new” imperial studies, has underscored the role of networks in shaping imperial projects. A networked approach offers a useful lens through which to analyse nineteenth-century steamship services, and in this paper I draw on such a perspective to focus on the operations of the Royal Mail Steam Packet Company (RMSPC). Importantly the RMSPC, unlike some of the other British Government mail-contract holding lines, operated across an archipelago as well as an ocean. In probing the significance of the RMSPC’s archipelagic context for the maritime network, this paper draws on a theoretical intersection between networked approaches to empire and island studies. I suggest that an examination of the maritime network through an archipelagic lens brings to the fore colonial priorities, imperatives and hierarchies that can appear flattened out through a networked approach alone. I argue for an archipelagic framing of analysis in order to heighten the local and regional significance of this transportation infrastructure, in effect foregrounding the relationship between the maritime service and mobilities in the Caribbean.

Journal of Geographic Information System (JGIS) , 2016, DOI: 10.4236/jgis.2016.85051
Abstract: The Densu basin is a coastal river catchment in southern Ghana and a typical rural community like all other rural settlements in Ghana. It is the only basin amongst 43 other basins of the country that supplies water to two regional capitals of Ghana, namely, the capital city of Ghana, Accra and Eastern regional capital, Koforidua. The qualities of these water resources vary naturally and widely depending on climate, season, and the geology of the bedrock, as well as anthropogenic activities. The primary aim of this research is to determine data requirements for efficient and cost-effective development of a Geographic Information System (GIS) to map and detect the extent of the sources of the watersheds and how to protect the environment for continuous supply of water. Among the Nine catchment areas, only one catchment? WSA_05 (Koforidua Township) was determined to have a very high risk of being vulnerable and therefore required urgency to protect environment for continuous supply of water. Four catchment areas WSA_02 (Weija Dam), WSA_03 (Apedwa-Asafo), WSA_06 (Suhum) and WSA_09 (New Tafo) were determined to have a high risk of being affected and therefore there was the need to protect the environment for continuous supply of water. Ghana as a country will have to take a responsible step in protecting its water body and its environment to enable continuous and sustainable supply of water to its citizens. This study therefore reveals the state of the water users and how urgent it environment needs to be protected.
Assessment of water quality in Ahor Lake - Ghana
R Amfo-Otu, ED Wiafe, BB Kocke
African Journal of Environmental Science and Technology , 2011,
Abstract: In the bid to boost the tourism industry, West Akyem Municipal Assembly identified Lake Ahor, a manmade lake as a potential tourism site in the municipality. However, the quality of the water is not known hence the assessment of the physical, chemical and bacteriological characteristics of the lake. A total of twelve samples of water from the lake were collected in June 2011 and were subjected to physical, chemical and bacteriological analysis. The measured water quality parameters included pH, colour, turbidity, alkalinity, TDS, total iron, nitrate, nitrite, trace elements like phosphates, zinc, copper, silicon, feacal coliform and Escherichia coli counts. The results showed that the averages for parameters like pH, colour, turbidity, alkalinity, TDS, total iron and nitrate were 6.6, 48.3 TCU, 4.8 NTU, 44.2, 1221.3 and 0.2 mg/l respectively. The tests for total coliform, faecal coliform, E. coli and total heterotrophic bacteria levels showed >8 CFU/100 ml for total coliform, between 1.00 and 8.00CFU/100ml for faecal coliform, 0.00 and 9.00 CFU/100 ml for E. coli and 42.00 and 155.0 CFU/100 ml for total heterotrophic bacteria. The water from the lake met the WHO guidelines in all parameters except the colour of the water which was light brownish which reduced the clarity at the deep areas of the lake. It is recommended that the appropriate authorities must demarcate safe swimming areas in the lake to prevent injury or drowning of those who will patronize the facility.

Richard Amfo-Otu,John Kwesi Bentum,Stephen Omari
Environment and Pollution , 2013, DOI: 10.5539/ep.v2n2p66
Abstract: The study investigated the level of heavy metal concentration in soils at e-waste recycling sites at Tema Community One. Two soil samples were collected from six different sites for laboratory analysis with a seventh location serving as a control. Heavy metals in soil samples were analyzed by digestion method and the use of atomic absorption spectrophotometer. The concentrations of Cadmium, Copper and Mercury were all higher at all the sites than those obtained for the control. The site that recorded higher concentration for copper was about 1200 times higher than the value for the control but statistically, there was significant difference between the concentrations of copper from the six sites (t = 5.168, p = 0.0036). Site 12 and GMG site had concentrations which is 5 times higher than the control and there was significant difference between the concentrations from the six sites and the control (t = 10.39, p = 0.0001) for the cadmium. The mean concentration of mercury from site 12 was found to be 34 times higher than the control value, however, there was no significant difference between the concentrations from the six e-waste recovery sites and the control (t = 2.593, p = 0.05194). E-waste recycling has contributed to the heavy metal contamination of the soil at the recovery sites. Workers safety in relation to these heavy metals is therefore worth researching in the future.

Environment and Natural Resources Research (ENRR) , 2012, DOI: 10.5539/enrr.v2n3p19
Abstract: Safe drinking water is essential to the protection of public health and well being of citizenry. The study investigated physico-chemical water quality parameters that could contribute to consumers’ complain from communities benefiting from small town water supply schemes in Ga East Municipality of Ghana. Three samples were collected from each borehole, duplicate physico-chemical analysis was conducted and the result was compared to World Health Organisation guidelines for drinking water. The parameters analysed were based on their ability to impart colour to groundwater, change taste and form scales on storage and pipe fittings. The result showed that, the pH (5.2±0.5, 5.3±0.4 and 5.1±0.2) of the three boreholes were below WHO recommended levels which made the water acidic and aggressive. The study reviewed that the borehole water were moderately hard (66.0±3.6, 91.3±5.1 and 73.7±3.5 mg CaCO3/L). These two parameters can cause rusting and scale formation in pipe fittings which could lead to consumer complains. Other parameters such as (Na+, Ca2+, Mg2+, Cl-, and SO42- mg/l) were within acceptable limits. Colour imparting ions like iron (0.1±0.0, 0.1±0.0 and 0.1±0.0 mg/l) and manganese (0.02-0.03 mg/l) were within WHO guidelines, were considered safe and had no major health implications on consumers. It was therefore recommended that liming should be considered to bring the pH level to an acceptable limit.
Relative efficacy of organic manures in spring barley (Hordeum vulgare L. ) production
Ofosu-Anim J,Leitch M
Australian Journal of Crop Science , 2009,
Abstract: The effect of organic sources of nutrients on the growth of spring barley (Hordeum vulgare L.) was studied in a pot experiment in a heated glasshouse at the University of Wales, Aberyswyth from November 2006 to March 2007. Spring barley seeds were sown in 120 pots containing a mixture of peat and 180g dry weight of poultry manure, cowdung, chicken manure pellet, sheep manure and horse manure. Chicken manure pellet was applied at 3.0 g pot-1 as top dressing. Mineralization pattern of the organic manures was monitored in a parallel experiment with 24 pots containing only the growth media. In this study, organic manures significantly increased plant height and chlorophyll content of leaves over the control plants. The application of inorganic fertilizer increased plant height over chicken manure and compost. In addition chlorophyll content was higher with inorganic fertilizer than cowdung at six weeks after germination. N mineralization significantly varied among organic manure sources with compost having the highest mineralized N and sheep manure the least. Plant tissue analysis revealed significant differences in plant tissue nutrient composition under organic manure treatment. Growing plants in organic manure resulted in 1.2 to1.6-folds, 1.1 to 4-fold and 1.1 to 4.1-fold increases in total N content of plant tissue at four weeks, eight weeks and twelve weeks after germination, respectively. Dry matter production by plants was also significantly increased under organic manure treatments. Organic manure application had the potential of increasing spring barley yield by 1.5 to 4-fold. Cowdung appeared to be the best source of organic manure for spring barley production.

Anim O. Ajake,R. N. C. Anyandike
Journal of Geography and Geology , 2012, DOI: 10.5539/jgg.v4n1p257
Abstract: This study evaluated forest management institutions and their initiatives in the rainforest communities of Cross River State. Data were collected through questionnaire survey and participatory research methodologies. Data generated were analyzed using descriptive statistics and one-way analysis of variance (ANOVA). The result of the analysis reveals that community forest management institutions and their initiatives have significant influence on forest ecosystem management than other institutions such as government and non-governmental organizations. The study discovered that community forest management institutions were rated very high in terms of sustainable harvesting techniques, encouragement of forest reservation and monitoring of forest management programmes among others. The other institutions were rated low in their influence on forest management. Based on these findings, the study suggested some remedial measures that will ensure sustainable forest management in the area, such as partnership forest management, alternative income generation opportunities and holistic consideration of the forest lands during management.

Journal of Sustainable Development , 2012, DOI: 10.5539/jsd.v5n11p93
Abstract: An assessment of some heavy metals concentrations in lettuce in irrigated with waste water in Tamale Metropolis in Ghana has been carried out. Analysis of water and lettuce samples revealed that the mean concentrations of Fe, Mn, Cu, Zn, Cd and Pb in lettuce were 0.436, 0.345, 0.068, 0.017, 0.04 and 0.038 mg/L and 0.167, 0.163, 0.104, 0.127, 0.142 respectively. With exception of Mn and Cd, the concentrations of heavy metals in the irrigation water, irrigated soils and irrigated lettuce, were within the FAO recommended levels. The mean concentrations of nutrients (NO3-N, SO4 and PO4-P) in the wastewater-irrigated lettuce, and well water-irrigated lettuce were 15.36, 0.88, 0.28 and 19.09, 1.117, 0.0573 respectively. Though, heavy metals concentrations in the lettuce were low, regular monitoring are required to prevent heavy metal accumulation with their attendant health implications in the consuming public.
