Evolution, Strategies and Problems of Poverty-Alleviating Agricultural Policies and Programmes in Nigeria  [PDF]
Rosemary I. Eneji, Fidelis Akwaji
Advances in Applied Sociology (AASoci) , 2018, DOI: 10.4236/aasoci.2018.812042
Abstract: According to the UNDP (2001) report, Nigeria started its independent nationhood in 1960 with poverty level of only 15% of population, but it is today struggling to reduce it from about 70% of its current population of about 190 million. This is in spite of the fact that the country is richly endowed with numerous natural, especially agricultural and mineral resources. Nigeria’s rising extreme poverty numbers are a direct result of years of negligent and ineffective government policies. Over-dependence on oil for years and an inability to generate non-oil revenue has led it to this. The country’s agricultural policy aims at reaching self-sustaining growth in the agricultural sector as well as the structural transformation required for the overall socio-economic development and improvement in the quality of life of Nigerians. The key feature of the policy is the evolution of strategies for ensuring self-sufficiency and the improvement of the technical and economic efficiency in food production. This is to be achieved through the introduction and adoption of improved seeds and seed stock, husbandry and appropriate machinery and equipment, efficient utilization of resources, encouragement of ecological specialization and recognition of the roles and potentials of small-scale farmers as the main drivers of food production in the country. Nigeria’s agricultural policy framework has evolved in a way that reflected, in a historical perspective, the changing character of agricultural development problems and the roles which different segments of the society were expected to play in addressing these problems. The form and direction of agricultural policy were dictated by the philosophical stance of government on the content of agricultural development and the role of government in the development process. Here, we examined Nigeria’s agricultural policy evolution from the colonial to the contemporary period. The very survival of Nigeria is tied to the ability of its economy to meet the material demands of its citizens since welfare constitutes a third objective of modern government. Food is an essential component of welfarism. The Nigerian Government and public policy makers must therefore see food as a component of welfarism and as such develop and sustain sufficient political will to achieve increased food production, a credible food policy and ultimately degrade poverty significantly.
Computer – Based Infrastructure Sector Interdependencies and Security Implications  [PDF]
Aghware Fidelis Obukohwo
Int'l J. of Communications, Network and System Sciences (IJCNS) , 2011, DOI: 10.4236/ijcns.2011.411090
Abstract: Traditionally, the analysis of sector interdependencies has involved the characterization of all infrastructure-to-infrastructure interconnections and some of the main infrastructure integrals that, once lost or be tampered with, will compromise the performance and security issues with the other interconnected infrastructures. Therefore, the paper dwells much on the security implications which may be associated with these infrastructure sector interdependencies. This paper also discusses some of the major risk considerations, analytical approaches, researches and the necessary developments needed as well as the interdisciplinary ranges through which the necessary skills are required in the construction of comprehensive sector interdependencies.

Open Journal of Soil Science (OJSS) , 2014, DOI: 10.4236/ojss.2014.412042
Abstract: The effects of petroleum products (kerosene, diesel, engine oil and petrol) treatment of soil at various sublethal concentrations (0.0%, 0.1%, 0.25%, 0.5%, 1.0%, 1.5% and 2.0%) on oxidative stress markers (lipid peroxidation, superoxide dismutase activity, catalase activity and xanthine oxidase) were studied in cowpea and maize seedlings. The results indicated that the petroleum products caused a significant increase in lipid peroxidation and a significant decrease in the activities of the antioxidant enzymes: Superoxide dismutase, catalase and xanthine oxidase activities. Kerosene had a greater effect on these indicators of oxidative stress than did the other petroleum products. The effects on lipid peroxidation and antioxidant enzymes were more pronounced in cowpeas seedlings than in maize seedlings.
Oil and Security in the Gulf of Guinea: Reflections on the External and Domestic Linkages
Fidelis Allen
Journal of Sustainable Development , 2012, DOI: 10.5539/jsd.v5n4p132
Abstract: The age-long significance of the West African Sub-region to global commerce or economy is not dwindling and, by all appearances, will not even in the distant future irrespective of shocks in the price of oil. Retrospectively, the region was key to European search for economic opportunities in both the pre-colonial and colonial eras as it provided the haven of resources needed for industrialization in Europe. A great number of slaves shipped from Africa to the New World were also taken from the region because of the advantage of huge oceanic freeway. Now, amidst threats of energy insecurity due to crisis in the Persian Gulf and increasing concern for securing reliable source of supply by oil importing countries, especially by the US, the Gulf of Guinea has come to the fore once more as a region with great potential for providing a significant part of the answer for emerging fears of global energy insecurity. This paper seeks to explain this role on the part of the Gulf Guinea in the context of external and domestic linkages to security and oil conflict in the region. The paper argues that quest for energy security and failure by oil importing countries to seek alternative energy sources breed insecurity for oil exporting countries. We suggest an explanation on how this operates, especially in relation to the mode of governance of the oil by national leaders, multilateral institutions and multinational oil companies in the case of Nigeria’s delta region.
Effect of Petroleum Products on Soil Catalase and Dehydrogenase Activities  [PDF]
Fidelis Ifeakachuku Achuba, Patrick Nwanze Okoh
Open Journal of Soil Science (OJSS) , 2014, DOI: 10.4236/ojss.2014.412040
Abstract: The effect of refined petroleum products on the activities of selected enzymes (catalase and dehydrogenase) was studied. There was a significant decrease (p < 0.01) in catalase activity. Catalase activity was higher in diesel and engine-oil treated soil after twelve days relative to petrol and kerosene. These observations indicate that the enzyme activity is the order of petrol > kerosene > diesel > engine oil. However, a significant increase (p < 0.01) was observed in dehydrogenase activity after twelve days relative to control values. Although, the refined petroleum products caused a similar pattern in the alteration of soil dehydrogenase activity, as they affected catalase activities, the general results indicate that the toxic effect is in the order of kerosene > diesel > petrol > engine oil. On the whole the results reveal that refined petroleum products alter soil biochemistry.

Knowledge Toward Cancer Pain and the Use of Opioid Analgesics Among Medical Students in their Integrated Clinical Clerkship
Maria Fidelis C. Manalo
Palliative Care: Research and Treatment , 2012,
Abstract: Introduction: Among the focal issues of barriers to pain management include the physicians’ lack of knowledge about cancer pain and negative attitudes towards opioids. Many physicians and educators attribute this, at least in part, to limited exposure to pain and palliative care education during medical school. Aim: The researcher investigated the medical students’ knowledge about cancer pain and the use of opioid analgesics. Methods: The subjects were a sample of 50 students of the University of the Philippines College of Medicine in their integrated clinical clerkship year. Descriptive statistics (frequencies, means, standard deviation, rating scales) were used to determine mean knowledge score and level of confidence with opioid use. The study also identified specific areas where students exhibited good or poor knowledge of opioids. Results: Approximately sixty-nine (69%) of the study respondents mentioned that pain management was given to them during their Anesthesiology lectures while a few recalled that they had these lectures during their Family Medicine rotation in Supportive, Palliative and Hospice Care. More than a third (35%) of the respondents admitted to not being confident with morphine use at present. The top three reasons cited as limitations in choice of opioids for cancer pain include fear of addiction, lack of adequate knowledge and experience and fear of side effects and complications. Out of a maximum of 13 correct answers, the mean knowledge score of the medical students was 6.6 ± 2.9. Less than 16% of the respondents had adequate knowledge on cancer pain and opioid use. Conclusions: The results show that basic knowledge of the role of opioids in cancer pain management among medical students in their integrated clinical clerkship year at the University of the Philippines is poor. The findings imply a need to look into making revisions in the medical curriculum to include a training program that will enable all students to graduate with basic competency in pain management and palliative care.
Performance of Recycled Asphalt Pavement as Coarse Aggregate in Concrete
Fidelis O. OKAFOR
Leonardo Electronic Journal of Practices and Technologies , 2010,
Abstract: Recycled asphalt pavement (RAP) is the reclaimed and reprocessed pavement material containing asphalt and aggregate. Most RAP is recycled back into pavements, and as a result there is a general lack of data pertaining to the mechanical properties for RAP in other possible applications such as Portland cement concrete. In the present study, some mechanical properties of Portland cement concrete containing RAP as coarse aggregate were investigated in the laboratory. Six concrete mixes of widely differing water/cement ratios and mix proportions were made using RAP as coarse aggregate. The properties tested include the physical properties of the RAP aggregate, the compressive and flexural strengths of the concrete. These properties were compared with those of similar concretes made with natural gravel aggregate. Results of the tests suggest that the strength of concrete made from RAP is dependent on the bond strength of the asphalt-mortar (asphalt binder-sand-filler matrix) coatings on the aggregates and may not produce concrete with compressive strength above 25 MPa. However, for middle and low strength concrete, the material was found to compare favorably with natural gravel aggregate.
Effect of Vitamins C and E Intake on Blood Lipid Concentration, Lipid Peroxidation, Superoxide Dismutase and Catalase Activities in Rabbit Fed Petroleum Contaminated Diet
Fidelis I. Achuba
Pakistan Journal of Nutrition , 2005,
Abstract: The effect of exposure to petroleum contaminated diet on the blood antioxidant defence system, lipid peroxidation and lipid profile as well as possible protective roles of vitamins E and C were studied in rabbits. Oxidative stress induction by crude oil was indicated by significantly (P<0.05) increased lipid peroxidation and a non-significant decrease in superoxide dismutase and catalase activities. A similar pattern was also detected in the lipid profile: total cholesterol and LDL-cholesterol insignificantly increased while HDL-cholesterol and triglyceride significantly decreased relative to rabbits fed normal diet. The reciprocal relationship between HDL-cholesterol and LDL-cholesterol in addition to compromised antioxidant enzymes could predispose exposed animals to coronary heart disease. However, pre-treatment of the diet with vitamins C and E exhibited a protective role on the toxic effect of crude oil on lipid profile, lipid peroxidation as well as antioxidant enzymes. The order of protection was vitamins E + C > vitamin E > vitamin C. These observations seemed to suggest that the protective role of vitamins C and E is synergistic. The protective role of the vitamins is probably time-dependent as significant (P<0.05) restoration of lipid profile as well as antioxidant enzymes activities to control values was effected after four weeks of exposure. It is therefore suggested that toxic effect of petroleum may be reduced by dietary supplementation of vitamins C and E.
