The present political and military situation in Ukraine has an important impact on the regional and global economic connections. EU28 and USA imposed sanctions against Russia. The main objective of this paper is to quantify the potential economic changes in the world economic environment by analyzing the most significant global economic actors: EU28, USA, Russia and implicitly BRICS. The analysis in the paper has to components: a post factum analysis, using the latest official data (2013) and an ex antum analysis, which is supported by a forecast until 2020. The analysis conclusions are supported by pertinent statistic tables and diagrams. It is assisted by the IBM-SPSS software. The main conclusion of the analysis is that Russia is not able to cut the economic connections with EU28 and USA on short and average term. Moreover, BRICS is not a viable solution for Russia at the moment. Contribution/ Originality
This study is one of very few studies which have investigated the new economic challenge related to the Ukrainian crisis which started this year. The paper is focused on the latest economic problem with global impact. The impact of this crisis and the solutions to solve it are far away of finding, yet.

Journal: Asian Journal of Energy Transformation and Conservation
In this study, a comparative optimization of biotransformation of benzaldehyde to L-Phenylacetylcarbinol via free cells of Saccharomyces cerevisae using Response Surface Methodology (RSM) and Artificial Neural Network (ANN) was done. A polynomial regression model was developed and RSM optimum process was determined. In developing ANN model, performance of ANN is heavily influenced by its network structure, five-level-five-factors design was applied, which generated 50 experimental runs from CCD design of RSM. The inputs for the ANN were cell mass (wet. wt), incubation duration (min), concentration of acetaldehyde (mg/100 ml), concentration of benzaldehyde (mg/100 ml), and β-cyclodextrin level (%): X5. The learning algorithms used was QP with MNFF and the transfer function was Tanh. The RMSE, R2, AAD and predicted values were used to compare the performance of the RSM and ANN models. The extrapolative fitness of ANN model was found to be higher than RSM extrapolative fitness model. Thus, it can be concluded that even though RSM is mostly used method for experimental optimization, the ANN methodology present a better alternative. Contribution/ Originality
This study contributes in the existing literature to science and engineering. This study uses new estimation methodology for the conversion of benzaldehyde to L-PAC. This study originates new formula to enhance the concentration of L-PAC. This study is one of very few studies which have investigated the use of β-CD to improve the L-PAC formation. The paper contributes the first logical analysis in modeling and optimization of L-PAC formation. The paper’s primary contribution is finding that L-PAC production can be enhanced using statistical software. This study documents the superiority of artificial neural network over response surface methodology.

Local Governance and Service Delivery in Zimbabwean Local Authorities: The Case of Harare and Masvingo Urban Municipalities
This study is an analysis of local governance and service provision in the Zimbabwean urban communities using Harare and Masvingo municipalities as case studies. It looks at the patterns of municipal service provision and residents’ access to these services. The study hypothesises that there is a general decline of municipal service delivery in Zimbabwe’s urban local authorities. The study argues that poor governance of urban local authorities affects the service delivery in the municipalities. The major research objectives of the study were to explore the extent to which residents are involved in the service provision decision-making processes in the two cities of Harare and Masvingo; to give an outline of the challenges faced by each of the two cities’ authorities in the provision of services to the public; and to draw lessons from the governance and service provision experiences of the two local authorities.Research methods involved both a theoretical review and an empirical study based on case studies, qualitative and exploratory approaches. The studied municipalities were found lacking in terms of involvement of residents in municipal governance issues and service delivery. Among other things, the study recommends full involvement of all stakeholders in the municipal governance processes. Contribution/ Originality
This study will contribute insight into both the debate and practice of local governance. It will contribute to the understanding of governance regimes that underlie the provision of services to residents of the selected cases. Through better understanding of the complexity and dynamics of local governance and service provision in the two cities of Harare and Masvingo, the study will provide lessons learnt on potentially the most critical issues as a basis for future reforms and practices in the governance and services provision in urban local authorities.

Adam Adem Anyebe
Journal: International Journal of Public Policy and Administration Research
The viewpoint often heard among students of development administration is that federalism is in conflict with national development planning; yet little is available by a way of empirical studies to demonstrate the influence of one on the other. This study was therefore undertaken to examine Nigeria’s planning experience against the background of its federal system of government. The study employed documentary sources and personal interviews for data collection. It was revealed among others, that Nigeria has not achieved a fully integrated national development planning because of its federal arrangement. It was therefore recommended that the intergovernmental planning institutions should be strengthened while the National Bureau of Statistics should be equipped with modern techniques for data collection, processing, storage and retrieval. Contribution/ Originality
This study contributes in the existing literature by adding the study of effect of federalism on National Development Planning in Nigeria. This study uses new estimation methodology of organizing interviews with planning officers. This study originates new formula of content analysis. This study is one of very few studies which have investigated planning in a federal set-up. The paper contributes the logical analysis of relationship between federalism and planning in Nigeria. The paper’s primary contribution is the finding that coordination of planning in a federal set-up is difficult. This study documents that the National Economic Council should be headed by the President of the country.

This research examines energy consumption of public housing in Sao Paulo, Brazil and how changes in the current design practice affect building’s energy consumption and comfort level. The hypothesis is that energy-efficient design concepts applied to the public housing design in Sao Paulo could significantly reduce energy consumption in buildings. Computer simulation is used to evaluate the current buildings’ energy performance and to simulate the performance of new energy-saving design strategies. The findings show that energy consumption can be reduced by as much as 54% by implementing the new design strategies. This study highlights the many opportunities for architects to change the public housing scenario in Sao Paulo. It showed that changes carefully applied to the current design process can significantly enhance building’s energy performance and comfort level inside the envelope. Contribution/ Originality
The paper’s primary contribution is showing that small changes in the design thinking, such as adopting more efficient building materials and considering the site’s natural features, can change the public housing scenario in Sao Paulo improving people’s life while promoting a more sustainable use of natural resources.

Structural Breaks and the Long-Run Stability of Demand for Real Broad Money Function in Nigeria: A Gregory-Hansen Approach
This study examines the long-run demand for real broad money function and its stability in Nigeria for the period from 1970 to 2012 inclusive. The study employs the Augmented-Dickey Fuller and Phillips-Perron tests for unit root, the Gregory and Hanson (1996a; 1996b) cointegration test to capture endogenous structural breaks in the cointegrating vectors of Nigerian long-run money demand function, cumulative sum of recursive residuals (CUSUM) and cumulative sum of recursive residuals squares (CUSUMSQ) tests for structural stability proposed by Brown et al. (1975). In estimating the canonical specification models, extended specifications are also presented. The results of the cointegration test suggest that demand for real broad money went through a regime shift in 2005. The results further confirm that there exists a long-run relationship amongst real broad money demand, real income, real domestic interest rate, real exchange rate, rate of inflation and foreign interest rate. However, the result of CUSUMSQ shows that the demand for money function is stable, but has undergone some temporary periods of instability. Hence, the apex bank in Nigeria can target the broad money (M2) aggregate to achieve macroeconomic objectives. Contribution/ Originality
The paper’s primary contribution is finding that the Nigeria’s demand for money function has undergone some periods of instability. This finding is in contrast with the findings of previous studies. This explains the inability of the apex bank to match money supply with money demand. Economics » The Economics and Finance Letters » Month: 04-2014 Issue: 4

Research Article
Author(s):
Wedajo Gebre
Journal: Current Research in Agricultural Sciences
In Ethiopia finger millet occupies 4% of the total area allocated to cereals (nearly half a million hectares) each year and also contributes about 4% to the total annual cereal grain production in the country. The production area increased from 342,120 ha to 368,999 ha with an increase of 7.3%, and the productivity increased from 3,769,290 to 5,241,911 quintals with a proportion of 28%. Six varieties (Tadesse, Padet, Wama, Baruda, Degu and Boneya) have been identified for cultivation to date. Though the varieties were initially released for cultivation in the sub-humid and mid altitude areas, their inadvertent introduction in to low rainfall areas found new adaptation zones. The production of these varieties has expanded to dry low altitude areas including regions where the crop was previously unknown. As a result of frequent drought, farmers in the dry rift valley region of Ethiopia widely adopted the variety that it is currently grown as one of the most important crops in this region. Therefore this study was initiated to discuss the production of finger millet in South Omo Zone, Ari woreda and generates information on the extent of finger millet production which is useful in designing suitable approaches for identifying gaps and intervening production constrains in the target area.The study areas comprised major finger millet producing kebeles of Ari woreda. Ten kebeles were selected systematically. Six year data on finger millet production and productivity was taken from woreda and each kebele. Data were collected through key informant interviews, focus group discussions, and questionnaires during a three-month period .Research in south omo zone, southern research institute and several national programs have resulted in considerable progress and identification of some improved finger millet varieties. The production of the crop in the study area is increasing. Contribution/ Originality
The aim of the present study was to measure the levels of technical, allocative and economic efficiencies of sesame producer and identify factors affecting them in selamago district of south Omo zone, Southern Ethiopia. The study was based on the cross – sectional data collected in 2011/12 production season from 120 randomly selected farm households. Stochastic production frontier model was used to estimate technical, allocative and economic efficiency levels, whereas Tobit model was used to identify factors affecting efficiency levels. The results indicated that there was substantial amount of inefficiency in sesame production in the study area. Accordingly, the mean technical, allocative and economic efficiencies of sample households were 67.1 per cent, 67.25 per cent and 45.14 percent respectively. Labor and seed were the variables that positively affected the production of sesame. Results of the Tobit model revealed that soil fertility, non farm income and credit access positively and significantly affected TE. Soil fertility had positive and significant effect on AE. On the other hand experience in sesame production, distance of sesame farm form residence, non farm income and extension contact affected AE negatively and significantly. Soil fertility, non farm income and credit access had positive and significant impact on EE. However, extension contact affected EE negatively and significantly. These indicate that there is a room to increase the efficiency in sesame production of the study area. Therefore, government authorities and other concerned bodies should take into consideration the above mentioned socio economic and institutional factors to improve productivity of sesame in the study area. Contribution/ Originality
In this paper the production efficiency of farmers in the study area and the factors that affect their efficiency in sesame production are identified. This study can be used as a reference for fellow researchers who are interested in the area of production economics specifically that deals with production efficiency.
Genotype × environment interaction (GEI) plays a significant role in determining the desirability or superiority of a genotype, hence the need to evaluate genotypes over wide range of environment. Seven improved cowpea genotypes were evaluated in four environments (years); the late seasons of 2009, 2010. 2011 and 2012 to determine their desirability based on mean grain yield and stability in Abeokuta South-western Nigeria using the Genotype+Genotype×environment (GGE) biplot. IT98K-573-2-1 had the highest mean grain yield while IFE-98-12 had the lowest. There was highly significant Genotype × Environment Interaction on seed yield (p<0.001) indicating the need for GEI analysis. The GGE biplot identified three mega-environments viz AB10 and AB11 as mega-environment 1, AB09 as the mega-environment 2 and AB12 as the third. IT98K-573-2-1, IT04K-333-2 and IT04K-227-4 were the most responsive genotypes in mega-environments 1, 2 and 3 respectively. IT04K-227-4, IT04K-333-2, IT98K-573-1-1and IT98K-573-2-1 were identified to have performed above average while IT99K-1060, LDP10-OBR1 and IFE-98-12 yielded below average. LDP10-OBR1 was the most stable genotype but was low yielding. IT98K-573-2-1 was selected as the best combiner of high yield and stability and the most desirable for Abeokuta South-western Nigeria. AB10 was identified as the best among the test environments. Contribution/ Originality
This study documents the responses of improved cowpea genotypes to different environments. Genotype by environment interaction continues to have high implications in plant breeding. IT98K-573-2-1 was identified as a well buffered genotype and therefore desirable for selection for further improvement.
This study was carried out to investigate the profitability of sheep production in Zuru local government area of Kebbi State. It examined the costs and returns of sheep production as well as problems encountered in sheep production in the study area. Data were collected from a total of 100 respondents using simple random sampling technique in 2014. Descriptive statistics and farm budgeting technique were used in the analysis of data. The costs and returns analysis indicated that, variable cost constituted 69.83% of the total cost of sheep production in the study area, while the fixed cost constituted 30.17%. However, the average total cost of production was N307, 491.57, the average total revenue was N376, 312.00, gross margin was N161, 572.43 and the net income was N88, 820.43 indicating that sheep production was profitable. Despite the profitability of sheep production, sheep farmers identified feed problem (92%) as their major problem. It is therefore, concluded that sheep production in the study area was profitable. With this level of profitability in sheep enterprise, it is recommended that this finding be disseminated to all practicing and potential sheep farmers in the study area and other communities. It is also recommended that more farmers in the study area and elsewhere should go into sheep production because of its profitability. There should also be practical application of new knowledge to sheep under traditional husbandry system in the study area. Contribution/ Originality
This study contributes in the existing literature on sheep production and livestock economics. Sheep production as an approach to economic growth could be relevant in improving the quality of life of farmers. Information on the economics of sheep production is necessary in view of the emerging food crisis in Nigeria.
In this paper, thermoelectricity based on copper(II) oxide CuO as semiconducting material is explored. The electrical properties of the samples were studied under different temperature gradients and pressures. Moreover, the effect of baking temperature was also investigated. CuO prepared using decomposition of Cu(NO3)2 as well as CuO nanopowder prepared using microwave-assisted synthesis technique were investigated and their results were compared. It was found that the current density can be enhanced with increasing the pressing pressure of the sample and when the sample undergoes a baking process. Moreover, it was found that the current density can be considerably enhanced with increasing the temperature gradient between the two ends of the sample. The CuO prepared using microwave-assisted synthesis technique was found to exhibit much better results over those of the CuO prepared using decomposition of Cu(NO3)2. Contribution/ Originality
This study is one of few studies which have investigated thermoelectricity based on copper(II) oxide CuO prepared using decomposition of Cu(NO3)2 as well as CuO nanopowder prepared using microwave-assisted synthesis technique.

Research Article
Author(s):
Adepoju T. F, Olawale O
Journal: International Journal of Chemistry and Materials Research
In an attempt to optimize the process condition of oil extraction from Neem seeds, Response Surface Methodology (RSM) was explored. 17 experimental runs were generated and were carried out based on controllable variables. The RSM predicted an oil yield (OY) of 45.717% (w/w) at the following control variable condition, ET= 30.00 min, NPW = 30 g and SV= 181.896 mL. Using these controllable variable conditions, the experiment was validated in triplicate and the average OY was obtained to be 45.650 % (w/w). Analysis on physicochemical properties of the OY showed that the oil was golden yellow in colour. The specific gravity and viscosity at 25 oC was found to be0.728 and 20.65 mm2/s, respectively. The percentage moisture content on wet basis and the refractive index at 40 oC were found to be 0.001 and 1.472, respectively. The saponification value and the iodine value were obtained to be 198 mg of KOH/g of oil and 112.31 g of I2/100g oil, respectively. The acid value was obtained to be 3.82 mg of KOH/g of oil while the % FFA was computed to be 1.91. The higher heating value and the cetane number of the oil were also obtained to be 39.63 MJ/kg and 48.60 MJ/kg, respectively. Gas chromatography analysis revealed that the oil is highly unsaturated. This work therefore showed the optimization and predictive capability of RSM in extraction of Neem oils. Contribution/ Originality
This study contributes in the existing literature to knowledge. This study uses new estimation methodology for conversion of Neem seed to Neem oil. This study originates new formula to improve the yield of Neem oil from Neem seed. This study is one of very few studies which have investigated the use of non-edible seeds to produced industrial based oil. The paper contributes the first logical analysis in optimization of oil extraction. The paper’s primary contribution is finding that non-edible oil can be obtained from agricultural plant. This study documents the effects of controllable variables on the units’ operation process.

Journal: International Journal of Geography and Geology
This study provides a preliminary assessment of the biophysical potential for carbon sequestration. Quantification of carbon stock and estimation of carbon sequestration potential was carried out in the Kpashimi Forest Reserve, Niger state, Nigeria. Carbon stock was measured in the six vegetation communities existing in the study area. Forty-eight randomly selected 20 x 20 metre quadrats were established wherein data was collected from the main forest carbon pools; including above ground tree, below ground root, undergrowth (shrub grasses), dead wood, litter and soil organic carbon. Biomass of the respective pools was quantified by destructive sampling and use of allometric equations. Thereafter, biomass values were converted to carbon stock equivalent. Four satellite imageries TM, SPOT, ETM+, and NIGERIASAT-1 of 1987, 1994, 2001 and 2007 respectively were used to estimate vegetation cover and carbon stock change over 20 years. The results showed that average carbon stock density (Mg C/ha) of the vegetation communities was in the decreasing order; Riparian forest (123.58 ± 9.1), Savanna woodland (97.71 ± 8.2), Degraded forest (62.92 ± 6.1), Scrubland (36.28 ± 4.1), Grassland (18.22 ± 5.1), and bare surface (9.31 ± 3.1). Deforestation and forest degradation between 1987 and 2007 have resulted in emission of 240.2 Mg (ton) C ha-1 at an annual rate of 12.01 Mg C ha-1. This suggests that the study site has carbon sequestration potential of 240.2 Mg C ha-1 based on its capacity to increase carbon stock through restoration; back to speculated 1987 levels and even higher. Thus, the study recommends the need to analyse carbon offset project feasibility in the study area. Contribution/ Originality
This study contributes in the existing literature by providing a preliminary assessment of the biophysical potential for carbon sequestration. This study demonstrates that forestry based carbon offset projects have the potential to act as a climate change mitigation tool and a means of fostering sustainable forest preservation in the developing countries. This study is the first of its kind in the woodland savanna ecological zone of Niger state, Nigeria.

Just-In-Time: Review of Empirical Studies
Research Article
Author(s):
PatrÃcia Raquel Ribeiro, Maria João Machado
Journal: International Journal of Business, Economics and Management
This study is a review of literature and empirical studies on the subject of Just-in-Time (JIT), conducted by a selection of articles published in international journals included in the ISCTE Business School Ranking, released since the 1980s to the present days. The purpose of this research was to compare the key features and benefits of JIT reported by the theory with the practice reported by companies in empirical studies already conducted. In addition, the percentage of use and the importance of JIT in different countries were also analyzed. A small case study of a Japanese enterprise – Mazda Motor Corporation – was also conducted in order to complement the investigation on the subject. As a result, it became clear that there were companies using JIT philosophy with distinct features and benefits that were not reported in the literature on the subject. The United Kingdom had the highest percentage of JIT use, and in broad terms, JIT was not frequently used in the majority of the countries surveyed. One reason for this can be explained by the fact that companies did not attribute a high degree of importance for JIT practices. This means that the companies analyzed did not implement JIT practices extensively. Contribution/ Originality
This study contributes in the existing literature because it allows a better perception of JIT philosophy. Through it is possible: to acquire a clear idea of the main benefits and key features of JIT; to identify in the different countries considered the use of in each stage of implementation.

An Assessment of the Perception of Christian Women of Family Planning Methods in Benue State
The unsustainable population growth in the country has necessitated the adoption of some measures aimed at achieving a lower population growth rate via voluntary fertility regulation methods. This study was therefore, undertaken to examine the perception of family planning methods by Christian women in Benue state. The methods employed in the collection of data were survey and documents. This work covered fifteen churches in Benue State, consisting of five churches each from the three senatorial zones. The fifteen churches comprise three thousand, one hundred and eighty registered women. However, three hundred and eighty women were selected as samples. Copies of questionnaire were administered randomly on the respondents. The data were subjected to statistical analysis using t-test. The study revealed that both the Protestant Christian women and the Catholic women agreed that the natural methods of family planning free them from the use of chemicals and help them space their children but with high failure rates. It was also revealed that the artificial methods of family planning reduce the fear of unplanned pregnancies while it was unanimously agreed that weight gain and high blood pressure are some of the major side-effects of the methods. The study therefore, recommended that women should be professionally counselled on their menstrual cycles before using the natural methods of family planning to reduce failure rates. There should also be regular workshops and seminars on the benefits and the side-effects of the natural and the artificial methods for enlightenment. Contribution/ Originality
This study contributes in the existing literature by adding the study of perception and family planning methods in Benue State, Nigeria. This study uses new estimation methodology of stratified-random sampling in the area of study. This study originates new formula of T-test to test the hypotheses instead of the normal descriptive statistics. This study is one of very few studies which have investigated family planning methods in Benue State. The paper contributes the logical analysis of perception and family planning methods in Benue State. The paper’s primary contribution is the finding that the major side-effect of artificial method is weight gain and high blood pressure. This study documents that experts should educate Christian women on artificial methods. Social Sciences » Humanities and Social Sciences Letters » Month: 12-2014 Issue: 4

Comparative Growth Analysis and Yield Performance of Glycine Max under Jatropha Curcas Based Agrisilviculture System of Agroforestry in the Northern Part of Bangladesh
This research was conducted at the Agroforestry Research Farm, Hajee Mohammad Danesh Science and Technology University to quantify the effects of pruning height in Jatropha curcas L. (Jatropha) and fertility levels of the recommended dose of NPK in Glycine max L. (Soybean) on crop growth parameters and yield in the agrisilviculture system of Agroforestry. The pruning in Jatropha and fertility level favored growth parameters with varying magnitudes. Six growth indices like CGR, RGR, NAR, LAI, RLGR, and SLW were observed to be higher under various pruning heights and reduced under no pruning. After that, scale of yield varied with pruning heights and fertility levels. Grain, straw and biological yield of 100 cm pruning height in Jatropha increased by 15.38 %, 13.74 % and 14.61 % respectively in comparison to sole crop and other pruning height level. At that time, I showed that these three yields of 100 % of the recommended dose of NPK (100 % RDF) in Soybean are comparatively higher than other fertility level. Hence, proper pruning system and optimum fertility level are important for improving Soybean yield under Jatropha based agrisilviculture system and it ensures higher income to the farmers and efficient land management compared to its sole cropping. Contribution/ Originality
This study is one of very few studies that are important for improving Soybean yield under Jatropha based agrisilviculture system than in sole cropping systems and it has the potential to develop the socioeconomic conditions of farmers.
