Abstract
This study was undertaken to evaluate the physical and chemical properties of three contrasting soils under four land use systems. The soil types considered were Vertic Cambisol, Haplic Lixisol and Ferric Luvisol while the land use types studied are cocoa plantation (CP), grazing land (GL), fallow land (FL) and cultivated land (CL). Soil samples were collected at 0-15cm and 15-30cm depths respectively from each of the locations. The soil samples were air dried and passed through a 2mm sieve and taken to the laboratory for analysis. The result of the study showed a higher sand content being recorded in Haplic Lixisol (CL) and Ferric Luvisol 2 (FL) followed by that of Vertic Cambisol (CP) and Ferric Luvisol 1 (GL) in the upper 0 to15 cm depth and lower 15-30 cm. The soil pH within the soil types and depths could be categorized as slightly acidic to moderately alkaline. The organic carbon content of the soils was generally low; it varied from 0.18% to 1.29 % for 0 to 15 cm depth with Vertic Cambisol (CP) having the highest value. The mean available P content was not significantly (P?0.05) different among the soil and land use types. The total nitrogen recorded was generally low 1.006 - 1.304% at 0-15cm while at the lower depth it ranged between 0.566 – 0.768%. The exchangeable bases also decreased following cultivation. The result of the study shows that continuous cultivation without adequate management practices causes a decline in the physical and chemical properties of the soil.
Contribution/ Originality
This paper contributes to existing literature that agriculture being the main user of land is constantly being affected by land use changes. It further seeks to assess how the physical and chemical properties of the different soil types are being affected by different land use types.

Abstract
The entrepreneurial skills have been regarded as the vital factor for the business sustainability. The previous study confirmed that there was a gap for entrepreneurial skills between several countries. The factor driven countries (such as Indonesia, Philippines, Vietnam, etc.) are dominated with the wholesale/retail activities, while the innovation driven countries (such as Sweden, Belgium, Norway, etc.) will be more dominated with ICT/Finance or the professional services activities. The wholesale/retail activity is said to be easier to enter since it’s generally require lower skill levels. Entrepreneurship education (EE) is needed to enhance the development of the entrepreneurs in order to fulfill this gap, so it is necessary to evaluate the EE program delivered by the university in shaping the entrepreneurial competencies. This research did an evaluation towards the entrepreneurship education program by identifying the learning process (including the definition and objectives of EE, the course contents, the teaching methods, and community outreach activities), and measuring the impacts (by using entrepreneurial competencies). This research was done in the Management of Business in Telecommunications and Informatics, Faculty of Economics and Business in Telkom University. The result is aimed to improve the learning process within institution. On the other side, this research is expected to help the university to achieve the target to be a Global Entrepreneurial University in 2038, particularly to create the global entrepreneurial graduates. This study is also expected to improve the economic growth by increasing the university’s role in creating the graduate entrepreneurs.

Export to    BibTeX   |   EndNote   |   RIS

Abstract
This paper examined the statistical approach adopted by schools to communicate their academic achievement to stakeholders. The paper looked at the most frequently adopted method, the use of percentage scores, and discussed the limitations of its usage. The paper also explored the use of the weighted average of scores and compared it to the use of percentage scores. Data from the West Africa Examinations Council and standardised test scores from a selected high school were used for the paper’s analyses and illustrations. The paper demonstrated that the weighted average of scores accounted for quality of grades obtained as well as the number of candidates presented by a school. The paper identified the use of weighted average of scores as a preferred option to percentage scores in communicating academic achievement to stakeholders.
Contribution/ Originality
This study documents the use of weighted average of scores as the preferable means of communicating student test scores to stakeholders.

Abstract
School enrolment and attendance for adolescent girls is a key priority for education sector in most developing countries. In Somalia, this is even more prominent given the low enrolment rate of girls and the gender specific challenges that the girls face. Girls in Somalia often remain absent from schools during their menstrual periods due to lack of hygiene facilities and the social stigma in using the facility where they exist. Girl Friendly Space (GFS) has been adopted as a means to mitigate these challenges. Despite strong narratives of the effectiveness of the GFS, there is lack of evidence on the impact of GFS on reducing school absenteeism. By using secondary data, this study explores the potential effects of GFS on reducing school absenteeism. The study indicate that having GFS in schools can reduce the likelihood of adolescent girls being absent from school in the past month by about 15 percentage points. Absenteeism due to ‘sickness’ is about 17 percentage points lower in schools with GFS compared to schools without the facility. Although this study cannot fully address the selection bias to claim these as impact estimates, the differences for boys between the two types of schools in absenteeism is much lower indicating possible effects of GFS on girls’ school attendance.
Contribution/ Originality
This study is one of very few studies that have sought to demonstrate potential effects of girl friendly spaces in reducing adolescent girls’ school absenteeism in culturally sensitive regions like Somalia. Primarily the study shows equipping and enhancing privacy in girls-only toilets can potentially reduce absenteeism up to 15 percentage points.

Abstract
The separation efficiency and palm kernel quality of five palm kernel shell separation methods used in selected communities in Rivers State, Nigeria were evaluated. The methods include traditional handpicking, clay-water bath (kaolin), mechanical dry separation, pneumatic and hydrocyclone separations. The weight of recovered palm kernels obtained from each separation method was determined and used in the calculation of separation efficiencies. Free fatty acid (FFA), shell/fibre and moisture content of the palm kernels recovered from each separation method was determined. The results show that the least free fatty acid (FFA) content of (3%) was found in sample separated by the pneumatic method and highest (8%) in the clay-water bath (kaolin) method. High moisture content of 11% was recorded for kernels separated by clay-water bath (kaolin). Pneumatic separation method retained the least percentage of shell/fibre content (2%). Hand picking and clay-water bath (kaolin) methods had shell/fibre retention of 8% and 6%, respectively. However, mechanical, pneumatic and hydrocyclone separation techniques conform to the quality parameters when compared to SON/NIS standard. The mechanical, pneumatic and hydrocyclone separation methods gave higher separation efficiencies of 74, 90 and 96% respectively and palm kernels of superior quality that meets the palm kernel industrial standards. There was no significant difference (P>0.05) in separation efficiencies between the traditional hand picking and the clay water bath methods however there was a significant difference (P<0.05) between the above two methods and mechanical, pneumatic and hydrocyclone separation methods.
Contribution/ Originality
This study shows that pneumatic and hydrocyclone separation methods are the most efficient in separating cracked palm kernel mixtures. This study also provide information on the best method of palm kernel recovery that meets quality requirement for Nigerian Industrial standard.

Objective: The study aims to assess the value of nuclear medicine and ultrasonography for diagnosing renal diseases among patients of different ages. Method: Quantitative analysis has been opted for evaluating the effectiveness of both imaging modalities for the diagnosis of renal diseases. 80 patients were targeted, who were having renal disease indications and they were diagnosed through modalities. The outcomes of both imaging techniques were compared through data analysis. Results: Positive findings of the nuclear medicine were observed between the age groups 0-12 years (58.1%), 13-24 years (16.1%), 25-36 years (1.6%), 37-48 years (9.7%), 61-72 years (3.1%) and 73-84 (8.1%) years of patients. Concerning the ultrasonography technique, positive effects were observed among the patients of age-group 0-12 years (58.7%), 13-24 years (17.5%), 25-36 years (3.2%), 49-60 years (3.2%) and 73-84 years (3.2%). The sensitivity rate for nuclear medicine was 100% as compared to ultrasonography, which was 93.6%. However, the specificity and accuracy rates for nuclear medicine were 78.4%, and 21.5%; however, similar rates for ultrasonography were 79.7%, and 13.92%, which showed better outcomes of ultrasonography. Conclusion: Ultrasonography was observed showing positive results among all age groups as compared to nuclear medicine imaging modalities. Future studies must focus on other imaging techniques to timely diagnose the disease and initiate the treatment before it get worse.
Contribution/ Originality
The study contributes to assess the efficiency difference between the nuclear medicine and ultrasonography to effectively analyze the case of the renal patients, before it gets severe. The study further documents the value of nuclear medicine in comparison with ultrasonography for the early diagnosis of renal mortal and morbid complications.

Journal: International Journal of Education and Practice

Export to    BibTeX   |   EndNote   |   RIS

Abstract
Over half of the children in the U.S. experience adversity early in childhood. These experiences, along with conditions in their families and neighborhoods, have profound developmental effects. The bioecological model of development includes these proximal contexts in a theory of development that incorporates the threats and supports present in these spaces to describe child development. This study used structural equation modeling to build latent measures of childhood adversity, family conflict, and neighborhood quality and tested theoretically-implied pathways to determine the relationships among these measures and cognitive outcomes in children. This study of US children ages 5-17 (N = 2,907) employed a nationally representative sample from the Panel Study of Income Dynamics to create and test these measures. Results indicate that adversity, family conflict, and a lack of neighborhood quality negatively impact cognitive function, even when controls for socioeconomic status and race are introduced. Testing of models indicated that family conflict and neighborhood quality are mediated by adverse childhood experiences, and these contexts should not be related to cognitive outcomes without the inclusion of adversity measures. This study provides further insight into the relationships among these contexts and children’s lives, and offers guidance for future research with these constructs.
Contribution/ Originality
This study contributes to the literature on Adverse Childhood Experiences and the Bioecological model of development by identifying the mediational nature of family conflict and neighborhood quality measures when relating ACEs to young adolescent outcomes. Additionally, the paper identifies and analyzes latent measures of these variables.

Export to    BibTeX   |   EndNote   |   RIS

Abstract
Online training permits or encourages a change in the teacher’s role. It is in this sense that the objective of this paper was to analyze the implications of the application of an unconventional model to the teaching process, supported by Information and Communications Technology (ICT) and incorporating new methodological paradigms into the teaching-learning process for course presentation and management, encouraging students to change the role they have played to date, given their preliminary training process, which has been based, nearly always, on a traditional model. Using online courses to support the student-centered teaching-learning process involves knowing what features the online teacher must have and how teachers can help their students in their new role. On the other hand, it is important to employ the lessons learned by traditionalist teachers, because the latter can take advantage of their experience to teach in a better way by implementing the use of information and communications technologies.
Contribution/ Originality
This study contributes in the existing literature a learner-orient environment for the teachers and students.in which it is attempted to recognize the importance that the teacher has in this current knowledge society, where undoubtedly the tutor has two decisive roles: offer feedback and manage and strengthen relationships between students-teachers. This study documents aspects such as communicating effectively and the Role of teacher as a central factor in the virtual learning environments

Abstract
Onion varieties were evaluated for adaptability to the climatic conditions in Benatsemay woreda. Three varieties of onion were planted under a complete randomized block design experiment with three replications at farmer’s field at Benatsemay woreda. Yield and yield component data like; plant height, number of leaves, bulb size and bulb yield of each varieties were collected. Bulb of all onion varieties were harvested at their maturity stage (90% tops down) and then weighted. SAS were used for data analysis. The result indicated that, the three varieties namely; Adama red, Nasick red and local contribute similarly to total yield, plant height, number of leaves and bulb size. The variety local was the best variety as it produced the highest bulb yield of 7.0033kg/plot numerically. Based on the result, we advise farmers to use local variety followed by Nasick red and Adama red therefore, government should promote these onion varieties for cultivation in Benatsemay woreda especially for Beneta kebele and its vicinity. Concerning body has to work together to ensure the availability of the seed of Local and Nasick red varieties. So that, onion producer can be interested for accepting these varieties for large scale production. The effects of different agricultural practices on yield of onion have to be considered for future investigation.
Contribution/ Originality
This study is one of very few studies which have investigated the potential of different onion varieties to increase the productivity and income of onion producer in the studied area and its vicinity.

Abstract
Fried cassava chips are largely accepted in Cameroon but their quality is not consistent. This study investigated the appropriate cassava varieties and soaking regime for processing good quality fried cassava chips. Fried chips were processed from four cassava varieties (0110, 8034, 92/0326, makumba) using four soaking regimes which were: unpeeled roots, soaked for 72 h, peeled roots, soaked for 24 h, peeled roots, soaked for 14 h and peeled sliced roots, soaked for 24 h. The proximate composition, physical characteristic and sensory test were done to evaluate the quality of fried chips obtained. Fried chips processed from variety 0110 presented the highest carbohydrate (77.94±0.34 %) and the lowest moisture (1.75±0.22 %) and fat content (15.11±0.30 %). The variety 8034 showed higher level of Ca, K, and Fe than other varieties. Variety 0110 was more salty, crispy and crumbly with higher global quality. Fried cassava chips processed from peeled soaked roots for 24 h scored the highest global quality as compared to other soaking regimes. Therefore, cassava varieties and soaking regimes influence the quality of fried chips. Socio-economic studies are warranted before large-scale dissemination of results to users.
Contribution/ Originality
This study is one of very few studies which have investigated the variation of the quality of fried chips with respect to different cassava varieties.

Author(s): Casper Agaton
Journal: International Journal of Sustainable Energy and Environmental Research

Export to    BibTeX   |   EndNote   |   RIS

Abstract
The Philippines is making a significant step to become energy independent by developing more sustainable sources of energy. The country sees investments in renewable energy and nuclear energy as promising alternatives to address the country’s problem in energy security. This paper evaluates the comparative attractiveness of either investing in alternative energy sources or continuing the use of coal for electricity generation in the Philippines. Applying the real options approach under coal price uncertainty, this study analyzes investment values and optimal timing of switching technologies from coal to renewable or nuclear energy. It also examines how negative externality and the risk of nuclear accident affect investment decisions. Results identify possible welfare losses from waiting or delaying investing in alternative energy. Negative externality favors investment in nuclear energy over coal, whereas the risk of nuclear accident favors investment in renewable energy.
Contribution/ Originality
This study contributes in the existing literature by applying real options approach to analyze investment strategies of shifting energy source from coal to renewable or nuclear energy considering the uncertainty in coal prices, risk of nuclear accident, and negative externality.

Abstract
In this paper, we show the parallel of Adomian Decomposition Method (ADM) and Lobatto-Runge-Kutta Collocation Method (LRKCM) on first order initial value stiff differential equations. The former method provided closed form solutions while the latter gave approximate solutions. We illustrated these findings in two numerical examples. ADM solutions were in series form while those of LRKCM gave sizeable absolute error. We further visualized our findings in respective plots to show the great potentials of ADM over LRKCM in providing analytical solutions to stiff differential equations.
Contribution/ Originality
This study contributes in showing the originality of ADM in obtaining exact solution to Stiff differential equations, while LRKCM provided approximate solution whose accuracy depended on step size.

Abstract
The implementation of the bottom-up model policy especially the Smith model has not been effective in implementing the policy of the National Program for Community Empowerment of Independent Urban Area, known as PNPM MP, in Makassar City. Through qualitative method with case study, performance of policy implementation of PNPM MP aims to assist and develop community through development trajectory, but new infrastructure development is quite successful, but economic development in business capital and socio-political development has not been effective. The program, for example; Social development problem is stagnant after much practice because it is not supported by the equipment work post training. The ability to manage revolving funds, and repayment of interest on loans, and cooperate with others economically. Politically they generally do not know it. The overall linkage is very weak, so it sometimes provokes confusion to frictions between stakeholders in the region. The cause of the problem is that stakeholders are adopting what is formulated as a poverty alleviation policy (PNPM MP). However, the policy does not provide the flexibility of stakeholders or target groups to change policy objectives. This means that the peasants program of poverty is not bottom up, but a combination of top down and bottom up.
Contribution/ Originality
This research contributes to the policy implementation literature which shows a new model of implementation of the national community empowerment program and this study finds the problem of economic development in the development of business capital and socio-politics has not been effective. This model contributes thought to the government to take effective policy measures.

Abstract
This study is designed to investigate the effects of exchange rate changes (volatility or variability) and other macroeconomic variables such as real exchange rates, real foreign and domestic income, terms of trade and lagged exports and imports on trade flows in Nigeria. The study examined the long-run macroeconomic factors of exports and imports in Nigeria using Johansen cointegration tests and analysis for the period 1971 to 2011 studied. The time series properties of the data were first analyzed using the Augmented Dickey – Fuller (ADF) tests to execute unit root tests for the relevant trade indicators. The study found a long-run cointegration relationship between trade flows and their determinants. It further discovered that exports and imports exhibit varied sensitivity to exchange rate risks (i.e volatility or variability). Thus, a stable exchange rate is recommended for expansion of trade and stable growth of the national economy as persistence in exchange rate volatility would snowball into a depression if not arrested on time via application of a managed floating exchange rate regime by the central bank of Nigeria. More-so, there are other viable policy options that should be adopted by the government to stop this sliding trend like restructuring the domestic economy from consumption to production using agricultural and industrial sectors diversification. In particular, the policy of a guided deregulation of foreign exchange market is strongly recommended instead of allowing the market forces to determine the value of the domestic currency vis-à-vis other key currencies of the world. This is because foreign currency is scare and sources of its inflow is few as at present.

Abstract
ZrTiO4 thin films were deposited by reactive dc magnetron co-sputtering method without heating. The crystal structure, surface morphology, thickness, optical and dielectric properties of the thin films were investigated. At sputtering currents above 2.0 A without heating ZrTiO4 thin film was crystallization of the orthorhombic phase (111). The values of refractive index were ranged between 2.01 and 2.23 (at 650 nm). The optical packing density values were ranged between 0.85 and 0.96. From this study, it was observed that the refractive index values were strongly dependent on packing densities. The high dielectric constant width decreases from 74.3 to 43.3 when sputtering current increases, which is higher than other research.

Abstract
The study investigated the drivers of banking stability in ECOWAS countries. The results show that the stability in the banking sector is mainly influenced by the banking spread (Net Interest Margin-NIM). However, it finds that crises in the banking sector pose a negative influence on stability. In addition, the result reveals that high percentage of foreign banks reduces stability in the banking industry. The impact of income diversification has a positive influence on stability even though the effect is weak. Similarly, the impact of more concentrated banking industry on stability is positive but insignificant.
