ABSTRACT

Bioaccumulation of heavy metals was studied using Hibiscus sabdarifa plant in a green house to investigate the absorption of copper (Cu), Lead (Pb) Zinc (Zn) and manganese (Mn) on a contaminated soil. Garden healthy soil samples were contaminated with various concentrations of these metals and H.Sabdarifa plant were grown on it in a pot for a period of 60 days. The roots and shoots organ of the plants were harvested and the samples were prepared and analyzed using Atomic Absorption spectrophotometer (AAS) in order to find out their phytoremediation potential. Result showed that heavy metal content in the plant tissue; roots stem and leaves were as follows: Cu1.00, 0.70, 0.60, (mg/kg), Zn, 5.2, 4.2, 2.00 (mg/kg),Pb  0.9,0.6, 0.5, (mg/kg),and Mn 1.50, 0.20 0.10 ( mg/kg) respectively. All the metals tend to accumulate mostly on the roots, stems and leaves and therefore decrease transfer probability to secondary consumers. Also the concentrations of heavy metals in the control samples were analyzed and compared. The results suggest that H. Sabdarifa plant could be used for the phytoremediation of copper, zinc, lead and manganese.

ABSTRACT

The economic development and transformation of any nation depends on quality of her human resources and competent entrepreneurs who possesses the innovative ability to start and manage businesses effectively. Entrepreneurship education dwells on developing understanding and capacity for pursuit of entrepreneurial behaviors, skills and attributes in widely different contexts. This competency can be achieved through practical entrepreneurship training. This paper examines the role of entrepreneurship education in economic transformation of African countries with particular emphasis on Nigeria; it review literature and two basic methods presently in used in Nigeria, the entrepreneurship education development called Entrepreneurship Education Development (EED) and the concept of CEFE methodology. The methodology used for collecting data was primary source through questionnaires, questionnaire was administered to 45 respondents who were participants during 2010 cefe entrepreneurship training in Federal polytechnic, Bida Niger State, Nigeria; of which 41 questionnaires was dully completed and returned. Analysis of data was done based on returned questionnaires. Findings reveals that most respondents who were participants strongly agreed that the cefe methodology would offer better opportunity for entrepreneurship and business management than Entrepreneurship Education Development (EED) as thought in our tertiary institutions. It was reveal that business plan carried out during cefe training can impact positively on business than the one offered by Entrepreneurship Education Development (EED) curriculum as presently thought in our tertiary institutions. Conclusion was drown and recommendations given which include the need for Cefe methodology to be integrated into academic curriculum of tertiary institutions in Nigeria, without restriction to field of study or discipline, this will afford students opportunity to learn more about practical entrepreneurship and business management competencies during the period of their studies, thereby becomes job creators instead of job seekers. This will eventually boost economic activities and leads to economic development. It was also recommended that the method demands strong support from governments at all levels, federal government, state and local governments, financial institutions and industrial promotion agencies, the business and academic communities at large. This is because respondents reveal that the effort of government support at all levels is not yet satisfactory.

ABSTRACT

The study investigated the use of management information systems in road traffic management in Nigeria. The population of the study was three hundred (300) motorists in Owerri, Imo State. To accomplish this task, two hypotheses were formulated. The Technology Acceptance Model was used to determine the level of acceptance of the Management Information Systems, while the Average Index Technique was used to test the two hypotheses. The results obtained showed that : (a) the adoption of Management Information Systems will improve road traffic management in Nigeria ; (b) road users appreciate the essence of Management Information Systems on Nigerian roads. Based on these findings, it was recommended that Management Information Systems should form a major component of traffic management in Nigeria.

ABSTRACT.

Now that Nigeria has witness a successful transition from civilian to civilian government over the years, it has become imperative to identify the role to be played by bureaucrats in sustaining and stabilizing democracy for effective development. The paper identified basically three important roles to be played by bureaucrats towards democratic stability. First, intensification of advisory role of bureaucrats to political leaders and modification of policy issues at implementation level when advice is given a deaf ear. Second, Bureaucrats should not play phsychophancy, because it is dangerous and can impede democratic process. Finally political neutrality principle should be strictly adhere to. it is hoped that if these roles are played sincerely by bureaucrats, it will help in stablilizing democracy in Nigeria.

ABSTRACT

This study analyses the behavior of the bilateral real exchange rate and fiscal variables in Nigeria from the period 1970 – 2012 to address the linkage between these variables. The analytical technique employed is that of the Ordinary Least Square and Instrumental Variable (OLS, IV) method using the Hildreth – Lu grid search method and by expanding the previously given list of the Instrumental Variable to include the once-lagged values and the relevant variables in establishing the relationship. The empirical result suggests that: Real devaluation improves fiscal balance and that budget deficit influences the behavior of real exchange rate. Again the increase in income associated with exchange rate depreciation increases import and depreciates the balance of payments. Hence the recommendation that the monetary authorities should adopt anti-inflationary measures (Fiscal and monetary restraints) to achieve real depreciation, and the production of import competing goods be encouraged so that a large proportion of increase in income arising from exchange rate depreciation is not spent on imports.

Keywords: Real Exchange rate, Fiscal expenditure, fiscal revenue, Nigeria.

ABSTRACT

The 2011General Election that was held marked the fourth general election in Nigeria since the democratically elected Government of General Olusegun Obasanjo assumed office in 1999 after about thirty years of Military rule in Nigeria. Elections in Nigeria since 1999 has been relatively peaceful but the General Election of the April 2011 recorded high level of electoral violence when compared with the elections in 1999, 2003 and 2007 respectively. The violence swept through twelve (12) Northern states of Adamawa, Bauchi, Borno, Gombe, Jigawa, Kaduna, Kano, Katsina, Niger, Sokoto, Yobe and Zamfara States respectively where there are lost of lives and properties worth millions of Naira. This paper x-rays the causes of the post April 2011 electoral violence amongst which are ethnic and religious inclination, rigging of election etc. The Paper recommends that until Nigerians and political leaders place the Nation and her economy above personal, ethnic and religious consideration, we cannot avert electoral violence.

ABSTRACT

Globalization is a world wide movement from local to a universal socio-economic system aimed at unifying the world market into a global village accessible to all, Nigeria as a nation cannot stop it but can only study its features and effects and key into enjoying the dividends of globalization. Theoretically, this paper X-rays the effects of globalization on the Nigerian economy with a thrust overview of its features, positive and negative effects to the country’s economy with the hope of proffering ways for sustainable development in Nigeria in the face of globalization. The paper concludes that Nigeria has not benefited enough from the globalisation owing to the undue dependence on crude oil exports, low manufacturing exports and the underdevelopment of the domestic financial markets. Globalization is a tool for development and knowledge but knowledge is power and knowledge is dynamic. The country must keep abreast with changes in knowledge. The main problem is that without the necessary facilities and knowledge, globalization is a mirage in the Nation’s economy.

ABSTRACT

The human immunodeficiency virus (HIV) infection is a global health problem, with UNAIDS estimating the global burden to be a total 33.3million. Africa with 10% of the world’s population is estimated to bear 67% of this. The first features of HIV/AIDS may be the oral lesions, and a number of dental patients have been offered HIV screening/test on finding of oral lesions suggestive of HIV/AIDS. The explosion of the HIV/AIDS pandemic in Africa has resulted in corresponding increase in the research and studies, making it necessary to review the information from studies. Objectives: To determine the prevalence of oral lesions of HIV/AIDS in Sub-Saharan Africa from included studies, To determine if the findings differ by gender or by region. Methods: An electronic search of four databases was carried out to identify studies that reported prevalence of oral lesions of HIV/AIDS. Results The prevalence of oral lesions reported was high. There were no significant differences in the occurrence of oral lesions in either gender. Prevalence increased with HIV/AIDS stage and deteriorating immunity.More studies will need to be done on the influence of potential confounders, such as lifestyles the immune status of infected individuals, and access to Health. 

Key Words: HIV/AIDS, Oral Lesions, sub-Saharan Africa
