Commercialization of smallholder farmers in climate change and logistic challenges

Research article of Global journal of Economics and Business Administration Commercialization of Smallholder Farmers in light of climate change and logistic challenges: Evidence from central Ethiopia Gutu Tesso Assist. Professor at the Institute of Cooperatives and Development Studies, Ambo University Commercialization smallholder farmer has been taken as one of the frontline strategies to extricate the community out of poverty and distinguish the nation among the middle income economies for the past several decades. Investments have been geared toward the same with only little progresses in the endeavor. Market participation and degrees of commercialization still remains unsolved puzzle. This paper investigates smallholders’ market participation, degree of commercialization and factors determining commercialization level using a survey of 453 HH in central part of Ethiopia. Household Commercialization Index (HCI) approach was used to measure degree of commercialization, while a double hurdle regression model was employed to identify the key determinants for market participation and degree of commercialization. The result indicates that significant proportions of HHs were still out of a product market and the degree of commercialization still remains very low. The policy recommendation is that government should focus on the boasting of production and productivity through fertility enhancements, improve access to market information through improved agricultural logistics, increased livelihood diversification, and build resilience to climate change induced shocks and stresses.

Violence among Nigerian Adolescents: A Threat to National Security

Research article of American Journal of Educational Research and Reviews Violence among Nigerian Adolescents: A Threat to National Security FAREO Dorcas Oluremi Department of Educational Foundations and Counselling, School of Education, Adeyemi College of Education, Ondo State, Nigeria. Violence among adolescents or youths is a universal problem, and it is so serious that it can have negative effects on victims and their families, friends and communities.. It is a phenomenon which in practice has led to a near breakdown of law and order, low productivity due to disruption of production activities, increasing crime rate, intra-ethnic hostilities, and harassment of prospective developers and other criminal tendencies. These alarming incidences of youth violence provoke this paper to identify types of youth violence, causes, effects, counselling strategies and recommendations. In conclusion, effective counselling to youths could go a long way in curbing violence. The role of counselling in the management of behaviour cannot be neglected; this is because a counsellor is the only professionally trained person who possesses the personal and professional skills required in managing such behavioural problem. Keywords: adolescents; youths; violence; types; causes; effects; counselling strategies ...

The further linguistic bifurcation of Punjab into Haryana and Punjab nearly twenty years after the first partition based on religion is the situation; political tension between the two newly carved states regarding the boundaries, water and electric power is the theme and as the capital of the two states, Chandigarh is the stage for the action. The relationship between politics and literature has been an interesting field of study. Irving Howe, whose Politics and the Novel is considered the locus classics on the subject, caste, “more than enough skepticism on the impulse to assign literary levels” and calls his book Politics and the Novel, but not Political Novel Keywords: Social Realities, Survival Strategies, Protagonists, dominant politics ...

Teacher’s views on students’ cognitive modelling competencies

Research article of American Journal of Educational Research and Reviews Teacher’s Views Regarding the Development of Students’ Cognitive Modelling Competencies and Modelling Implementation Process Ayşe TEKİN DEDE and Süha YILMAZ 1 Dr, Dokuz Eylül University, Izmir, TURKEY 2Assoc. Prof. Dr., Dokuz Eylül University, Izmir, TURKEY The purpose of the study is to reveal a mathematics teacher’s views regarding the development of 6th grade students’ cognitive modelling competencies and modelling implementation process. She conducted a long-term modelling sequences aiming at the competency development and was interviewed after the implementation process. Her answers were analyzed by using content analysis and the views were gathered under some themes and codes. It was seen that the views were shaped under seven themes as providing the development of each modelling competency, development of cognitive modelling competencies, factors contributing the development of cognitive modelling competencies, factors preventing the development of cognitive modelling competencies, implementation process, future implementations and factors required to be fixed in the implementation process. Some strategies supporting the development of the cognitive modelling competencies were appeared from her statements. She also indicated her general thoughts about the strengths and weaknesses of the implementation process. It is suggested for further studies to utilize the factors and strategies revealed in the study for planning modelling implementations. Keywords: Cognitive modelling competency, mathematics teacher, modelling sequence, teacher view ...

Heavy metal levels in soils and three herbaceous species in phytoremediation

Research article of Journal of Plant and Environmental Research Assessment of Heavy Metal Levels in the Soils of Ohyia Kaolin Mining Site and Screening of Three Local Herbaceous Species for Use in Phytoremediation C.E.

Okafor4 1Lecturer, Environmental Management and Toxicology, Michael Okpara University of Agriculture, Umudike, 2Senior Lecturer, Environmental Management, Michael Okpara University of Agriculture, Umudike, 3PhD Student, Michael Okpara University of Agriculture, Umudike, 4Lecturer, Environmental Management and Toxicology, Michael Okpara University of Agriculture, Umudike The study assessed three local plant species Chromolaena odorata, Ipomoea involucrata and Mariscus alternifolius commonly found at abandoned kaolin mining site at Ohiya, Umuahia Abia state for their efficacy in phyto-remediation of heavy metals contaminated soil using a pot experiment. Soils from Ohiya kaolin mining site were used as medium for growing the species. Pre-experiment assessments of the concentrations of six heavy metals (Cr, Pb, Ni, Cd, Co and Se) were carried out in the soil and plant tissues to be used for the experiment. The experiment was laid out in a Randomized Complete Block Design (RCBD) with 6 replicate pots each. The physico-chemical properties of the experimental soil showed high content of lead (Pb) and cobalt (Co) contamination which were (2.40mg/kg) and (9.84mg/kg) respectively. Post-trial plant analysis revealed that the three plant species used for the study accumulated appreciable quantities of the heavy metals. The ranges of Pb in the species were as follows C. odorata (0.80-1.00mg/kg), I. involucrata (1.00-2.00mg/kg), M. alternifolius (0.40-0.70mg/kg). The ranges of Cr were: C. odorata from (0.00-0.07mg/kg), I. involucrata (0.30-0.42mg/kg), M. alternifolius (0.01-0.10mg/kg). The ranges of Cd in the species were: C. odorata (0.02-0.30mg/kg), I. involucrata (0.10-0.70mg/kg), M. alternifolius (0.10-0.60mg/kg) and Co concentrations were: C. odorata (2.00-3.07mg/kg), I. involucrata (2.01-4.01mg/kg), M. alternifolius (2.01-2.10mg/k). Ipomoea involucrata had significantly higher accumulation of Pb and Co ...

O.1 and Ibtehal, M.A. Ahmed2 1 Veterinary Research Institute, P.O. Box: 8067 (Al Amarat), Khartoum/Sudan 2 Faculty of Medicine University of Khartoum/ Sudan Toxicity of Indigenous plant Ambrosia maritima was investigated. Twenty fore, 6-8 month old, 12 female and 12 male of Sudanese Nubian goats were used. Dried Leaves powder of Ambrosia maritima was mixed with water and given orally by drench to the animals at a dose of 1000 or 2000mg/kg/day for 126 days. Two females drenched the plant at a dose of 1000mg/kg/day, were died at day 8 and 9 post treatment and one female drenched the plant at a dose of 2000/kg/day died at day 13. The results revealed that goats drenched the plant for 126 days, showed chronic toxicity evident by clinical symptoms, pathological and biochemical changes. The main symptoms were watery diarrhea, inappetance, respiratory distress and depression. Later these symptoms disappeared and the animals appeared healthy. The most evident pathological features were hydrothorax, hydropretonium, hydropericardium, and enlargement of the liver. Histopathological changes were exemplified by degeneration and necrosis of the hepatic cells. Focal necrosis, congestion and haemorrhag of proximal convoluted tubules. Necrosis of intestinal vili with severe infelteration of inflammatory cells. Congestion of alveolar capillaries and pancreatic hyperplasia. These changes were correlated to the activity of Asparate Aminotransferase (AST), Alkaline phosphate (ALP), the concentration of cholesterol, sodium and potassium in the serum, and with the hematological values. The effect of the plant on males was less marked compared to that on female goats. There was gradual increase in mean body-weight of both sexes.
