Microcredit Schemes: A Tool for Promoting Rural Savings Capacity among Poor Farm Families: A Case Study in the Eastern Region of Ghana  [PDF]
Mercy Asamoah, Franklin Manu Amoah
Open Journal of Social Sciences (JSS) , 2015, DOI: 10.4236/jss.2015.31003
Abstract: Savings mobilization is crucial for any viable economic and investment activity. In rural agricul-ture, the ability to save or to mobilize capital in cash at bank or stock of wealth is a major prerequisite as the collateral for accessing bank loans. The ability to save among rural poor households is however, difficult due to their low income levels and inability to make personal savings commitment. According to Yunus (2000) [1], failure of traditional financial institutions to extend credit to the poor is the single most important reason for the perpetuation of poverty. Nevertheless, since the early 1980s, microfinance scheme has been identified as a useful tool that can effectively mobilise savings among poor households. Yunus (2003) [2] indicated that micro-credit schemes have developed unique characteristics in terms of unconventional approaches, organizational and lending procedures that have resulted in high rates of repayments, savings mobilization and the ability to nurture a culture of commitment and self-reliance of poor people. The objective of this study was to assess the role microfinance plays in savings mobilization among farm households, analyse the extent of savings mobilized by participants and evaluate the conditions for membership of such schemes. A total of 212 respondents in organised cocoa farmer Associations since 2010 in the Eastern region were interviewed using formal questionnaires. The results indicated that the microfinance model had helped the respondents, mainly small-scale cocoa farmers, to mobilize substantial savings in a convenient and tailor made way. The majority who did not have any savings culture before joining the schemes were surprised about their savings potential through the group concept. Also, the schemes allayed the fear of the participants to take credit from financial institutions with high (over 95%) repayment culture using peer support, group guarantee and social capital generated through the formation of associations. They also had easy access to farm inputs such as fertilizer to maintain their cocoa farms because of their savings mobilization. It is concluded that microfinance model is a potential tool that promotes savings culture which gives access to credit for small-scale cocoa farmers to purchase farm inputs to increase productivity and enhance their livelihood.

Adoption of recommended technologies as a package is the prelude to increase cocoa productivity per unit area. This is due to the interactive benefits of individual technologies which have been recommended by the Cocoa Research Institute of Ghana (CRIG). However, many surveys among cocoa farmers have reported low adoption of technologies resulting in low productivity of cocoa with an average of 450 kg/ha among small holder cocoa farmers in Ghana. The current study investigates the adoption behavior of some cocoa farmers belonging to some self help farmer associations in the Eastern Region who are being monitored by CRIG since 2011. Primary data was collected from 131 respondents using questionnaires to interview farmers between 2013 and 2015. The results showed that adoption of recommended cocoa technologies as a package was still low. Respondents, however, identified a number of challenges including high cost of inputs, lack of finance and access to credit, high cost of labour and old age as some factors hampering composite adoption of the full CRIG technologies. It is recommended that small-scale cocoa farmers need a sustainable and convenient microfinance that can motivate and help them afford the cost associated with the full package of technologies. Farmers’ savings culture should also be nurtured to enhance their financial capabilities and investment in the cocoa farm.

Abstract: Kola (Cola nitida) is an important economic cash crop for many West and Central African countries. It has several medicinal uses in the pharmaceutical industries and also plays a major role in traditional marriages among Islamic communities across West and Central Africa. The crop is extensively cultivated in Nigeria and Ghana. However, it exhibit signs of total and partial sterility as well as self incompatibility when propagated from seeds in most cases. Therefore, grafting is seen as a method of choice in addressing the problem stated above. Though grafting accounts for some degree of success, there is the need to assess genotypic and physiological factors that account for high or low grafting success. Genetic and physiological factors (such as rootstock age) affecting grafting success and growth in kola (C. nitida) were investigated in two separate experiments. In experiment I720 kola seedlings were raised from unselected kola nuts and sown at two monthly intervals. Four groups of seedlings (180/group) i.e. 6, 8, 10 and 12 months old were thus produced. Three different scions (A1, A12 and JB1) measuring (5-10 cm) were grafted onto the four age groups of rootstocks, namely, 6, 8, 10 and 12 months. Experiment II consisted of 540 seedlings raised from three main crosses (JX1/9 × JX1/11 * B1/142 × B1/151, JX1/9 × JX1/11 * B2/177 × B2/156 and JX1/9 × JX1/11 * GX1/46 × GX1/53). Grafting was done after six months using the same set of scions as described in experiment I. Experimental design used was 3 × 4 and 3 × 3 factorial designs in completely randomised design with three replicates for experiment I and II respectively. The fixed effects were the different genotype and age of rootstock at grafting whilst the response variable was the percentage of successful grafting two months as well as growth at six monthly intervals. Results from the study showed that grafting onto 6 months old stocks gave the highest percentage success and growth of grafts followed by 8, 10 and 12 months old rootstock in that order in both trial years. The study revealed also a significant rootstock and scion interaction (P < 0.05). We conclude that successful grafting in kola depends on rootstock genotype such as JX1/9 × JX1/11 * GX1/46 × GX1/53 and has been proven suitable for use in future kola propagation studies. Nonetheless, suitable rootstock with high grafting success does not translate into vigorous scion growth.

Design and Comparison of Controller for the Reduction of Conducted Electromagnetic Interference in an Inverter  [PDF]
P. Narasimman, E. Latha Mercy
Circuits and Systems (CS) , 2016, DOI: 10.4236/cs.2016.77100
Abstract: This paper presents the design of a controller for the measurement and reduction of conducted Electro Magnetic Interference (EMI) caused in the power electronic circuits. The conducted EMI is also separating the Common Mode (CM) and Differential Mode (DM) simultaneously using Line Impedance Stabilization Network (LISN). EMI is mitigated by the fuzzy controller. By comparing common mode voltage with the standard reference value, the generated error can be minimized by using fuzzy controller. Fuzzy controller is varying the PWM signal of the power electronic switching devices for reducing the electromagnetic interference. In this paper, comparison of PI and fuzzy controller of the open loop and closed loop models are implemented using MATLAB® SIMULINK for measurement and reduction of the EMI level; and also simulation results of the PI controller and fuzzy controller analysis are presented in this paper. The fuzzy controller is provided to achieve the EMI level of the inverter within the standard limit.
Mother tongue policies and mathematical terminology in the teaching of mathematics

Abstract: The Department of Education in South Africa advocates collaborative and constructivist learning; however, observations indicate that little discussion occurs in most multilingual mathematics classes. In this paper we draw on a pilot study set in the Eastern Cape where teachers were introduced to the theory and practice of exploratory talk, and then tasked to perform an action research project on introducing discussion in their own multilingual mathematics classrooms. The results of the study suggest some successes in terms of teachers initiating exploratory talk and highlight the fact that these successes were only achieved where code switching between English and isiXhosa formed an integral part of the process.
Servicing land for housing development in peri-urban areas of Kumasi, Ghana: theory versus practice
SE Owusu, KB Asamoah
Journal of Science and Technology (Ghana) , 2005,
Abstract: Since the 1950s, developing countries have been experiencing phenomenal growth in urban population and this is reflected in high demand for housing and residential land. In Ghana, the rapid population growth of the national capital and the regional capital towns including Kumasi has brought to the fore the need for more land for residential development. However, the rate at which urban land is being released for housing development by the traditional authorities is not commensurate with the rate at which it is being serviced. This has created problems whereby residents in newly developing housing areas lack basic facilities and services. This paper examines the factors and problems militating against orderly development of infrastructure in the peri-urban housing areas in the Kumasi Metropolitan Area. The paper suggests interventions aimed at addressing the problems related to the provision of infrastructure and services in peri-urban settlements of Kumasi, Ghana.
A contact-waiting-time metric and RNA folding rates
Asamoah Nkwanta,Wilfred Ndifon
Quantitative Biology , 2009,
Abstract: Metrics for indirectly predicting the folding rates of RNA sequences are of interest. In this letter, we introduce a simple metric of RNA structural complexity, which accounts for differences in the energetic contributions of RNA base contacts toward RNA structure formation. We apply the metric to RNA sequences whose folding rates were previously determined experimentally. We find that the metric has good correlation (correlation coefficient: -0.95, p << 0.01) with the logarithmically transformed folding rates of those RNA sequences. This suggests that the metric can be useful for predicting RNA folding rates. We use the metric to predict the folding rates of bacterial and eukaryotic group II introns. Future applications of the metric (e.g., to predict structural RNAs) could prove fruitful.

Abstract: Surface water basins all over the world are very crucial in irrigation industries. Irrigation schemes are particularly crucial in the agricultural economies due largely to the fact that global climate change has led to drastic changes in rainfall patterns. As a result, rain-fed agriculture alone is no more sustainable and irrigation schemes are being encouraged as poverty reduction/eradication strategies in the developing countries. This study was conducted to assess the overall controls on surface water resources in the coastal and south-western river basins in Ghana, and determine the suitability of these surface waters for irrigation activities. Multivariate statistical methods were applied to data on the physico-chemical parameters from the coastal and southwestern river basins. This study finds that the quality of surface water from these basins is controlled principally by leachate of chemicals from solid and mine wastes, the chemistry of rainfall, weathering of underlying silicate mineral-rich rocks and sediments, agricultural and domestic wastes. All the parameters are within the acceptable national concentration ranges for most domestic and industrial purposes. Sodium adsorption ratio (SAR) was used to assess the quality of water from the two basins for irrigation activities. The SAR values for all the months and years sampled are lower than 4 and the electrical conductivity values are equally low due to generally low ionic concentrations. When plotted on the Wilcox diagram, the data for all the months for the two years of the study, plot within the “excellent to good” category, suggesting that water from the area is of acceptable quality for irrigation activities.

Journal of Environmental Protection (JEP) , 2012, DOI: 10.4236/jep.2012.36061
Abstract: We conducted a study on a model drinking water distribution system to evaluate the impact of nutrient in the form of sodium acetate on the growth and survival of coliform and heterotrophic plate count (HPC) bacteria for a maximum of 21 days residence time of water in pipes. Our results show that, besides the nutrient added and the absence of any additional source of contamination and additional supply of nutrient, there was significant growth of the above mentioned bacteria in the pipes and bottles for a couple of days, after which the bacterial population began to decrease. The results indicate that the bacteria used the nutrient to grow and multiply until the nutrient was totally consumed and became depleted in the bulk water phase, after which the bacterial population reached a near stationary level and subsequently declined. This suggests the death of some of the bacteria and their dead cells were used by other bacteria for growth and survival. Using a detection limit of 3.3 CFU/100 mL for the coliforms, the study shows that after sometime, no bacteria were found in the water phase of the pipe, however, the biofilm in the pipes still harbored some of the bacteria. The results have revealed that the bacteria also have the tendency to move from the water phase to the biofilm since the latter provides a more suitable environment for bacteria to thrive on and grow, thus prolonging their survival in the system.
