Political Elite Theory and Political Elite Recruitment in Nigeria

This paper is on political elite theory, its application and relevance to political elite recruitment in Nigeria. It gives an analysis of the elite theory and further enunciates its principles, tenets, ideas, assumptions, application, strengths and weaknesses. It also traces back the issue of political elite transformation, succession or change to communal life in ancient Africa and further analyses the process of political elite recruitment in Nigeria from independence in 1960 to 2015 in the fourth republic. The paper observes that political succession in ancient and pre-colonial Africa was crisis-ridden and that the process of political elite recruitment in Nigeria since independence in 1960 to 2015 was full of flaws, manipulations and anti-democratic tendencies in allusion to basic assumptions or ideas of political elite theory. The paper therefore concludes that the elite theory is very apt, applicable and relevant as a framework of analysis for political elite recruitment in Nigeria. Keywords: Elite circulation, leadership re-cycling, oligarchy, political elite, political mafia, political power, power broke

Political Parties, Party System and Leadership Recruitment in Nigeria Since Independence in 1960

This paper is based on political parties, party system and political leadership recruitment in Nigeria since independence. The objective of the paper is to trace the political history of Nigeria from independence particularly in the area of political leadership recruitment, outline the failures recorded so far and make suggestions for improvement through appropriate reforms by Nigerian political parties. It elucidates on the important roles of political parties and the relevance of party system in political leadership recruitment in a democratic political system. It espouses such concepts as political parties, party system, political ideology, political culture and political maturity in relation to political leadership recruitment and formation of governments in a democracy. It adopts historical and sociological approach to capture and chronicle the various attempts made by Nigerian political parties in recruiting credible political leaders for the formation of governments and the many times they have failed in the process from the first republic in 1960 to the fourth republic in 2015. It observes to date that inter-and intra-party crisis is yet to come to an end and more than any other reasons, has gone a long way to affect the functions and responsibilities of political parties as veritable tools for political leadership recruitment. In view of the above, the paper suggests some reforms which if carried out, may strengthen Nigerian political parties as veritable tools for effective political leadership recruitment

Evaluation of Physical and Mechanical Properties of Selected Wood Species obtained from Saw Mills in Akure, Nigeria

The strength and sorption properties of selected wood species obtained from saw mills in Akure Nigeria were investigated based on key index properties such as density, bending strength and dimensional stability using appropriate standard experimental techniques. Data obtained from the experimental investigation revealed that the wood species ranged from low density 442.8 kg/m3 for Terminalia superba (Afara), through medium density 464 kg/m3 and 552.8 kg/m3 for Pycnanthus angolensis (Akomu) and Gmelina arborea (Gmelina) respectively, to high density 635.7kg/m3 and 678.2 kg/m3 for Milicia excelsa (Iroko) and Stereospermum acuminatissimum (Omo cedar) respectively. The bending strength values obtained qualified the wood species classification into low bending strength (25 N/mm2 – 75 N/mm2 ) for Afara, Akomu and Gmelina and the medium static bending strength in the range (75 N/mm2 – 125 N/mm2) for Iroko and Omo cedar. Furthermore, results of volumetric shrinkage and swelling are 7.21%: 5.04%, 7.75%: 5.26% and 7.84%: 6.69% for Afara, Akomu and Gmelina respectively while Iroko and Omo cedar recorded 10.95%: 7.84% and 11.08%: 11.08%. These updated results could be useful for wood selection for building construction application; for structural members in roofing, posts and beams

HEAVY METALS IN THE MYONEMATIC, HEPATIC AND RENAL TISSUES OF THE AFRICAN CAT FISH (Clarias gariepinus) FROM OGBA RIVER, BENIN CITY, NIGERIA.

The concentrations of heavy metals (Pb, Cd, Zn, Cu, Cr and As) in the myonematic, hepatic and renal tissues of the African catfish (Clarias gariepinus) from Ogba river, Benin City, Nigeria, were determined using a Unicam 929 series atomic absorption spectrophotometer. The concentrations of the aforementioned metals were also determined in water. The mean concentration of Pb ranged from 0.19mg/kg (muscle) to 0.39mg/kg (liver) while the mean concentration of Cd ranged from 0.03mg/kg (muscle) to 0.09mg/kg (liver). The mean concentration of Zn ranged from 0.09mg/kg( muscle) to 0.33mg/kg (liver) while the mean concentration of Cu ranged from 0.23mg/kg (muscle) to 0.76mg/kg(liver). The mean concentration of Cr ranged from 0.19mg/kg (muscle) to 0.41mg/kg (liver) while the mean concentration of As ranged from 0.36mg/kg (kidney) to 0.54mg/kg (muscle). The mean concentrations of the heavy metals in water were Pb(0.09mg/l), Cd(0.04mg/l), Zn(0.01mg/l), Cu(0.53mg/l), Cr(0.38mg/l) and As(0.59mg/l). With the exception of Cu, the mean concentrations of the heavy metals in water were generally above the World Health Organization (WHO) maximum allowable limit for the respective metals in drinking water implying that water from the river is unfit for human consumption owing to heavy metal contamination. The mean concentrations of Cr and As exceeded the WHO maximum allowable limits for fish food. The direct implication of this finding is that people who consume fish from the river are liable to potential health hazards resulting from Cr and As contamination.Â

Haematological Indices of Broiler Chickens Administered Water Containing Medicinal Plant Leaf Methanol Extract

The discovery that the use of antibiotics in animal production is fueling the increasing problem of transmitting resistance bacteria from food animals to man has led to the search for an alternative to the use of antibiotics. Therefore, the response of broiler chickens fed various medicinal plants methanol extract as a replacement for antibiotics was investigated. The plant extracts encompass four available leaves; Gercinia kola (Bitter Kola), Alchornea cordifolia (Christmas bush), Pterocarpus santalinoides (Red scandal wood) and Chromolera Odorata (Hagony or Siam weed). A total of 180 unsexed Ross strain broiler chickens were randomly assigned to these dietary treatments which had 30 birds each. The treatments were replicated thrice with 10 birds per replicate in a Completely Randomized Design (CRD). Feed and water were provided ad libitum throughout the experiment which lasted for 56 days. Haematological indices of broiler chickens were evaluated. Significant differences (p<0.05) were observed in the mean values of all the hematological parameters measured across the treatment groups, except Packed cell volume and White blood cell. The result values obtained in this present study were within the standard range of PCV of normal birds with the reference range of 25.0 - 45.0%. However, the values obtained did not reveal any health problem. The findings of this study conclude that the medicinal plant methanol extracts have considerable potentials as component of broiler chicken diet. Alchornea cordifolia plant methanol extract can successfully be used to replace antibiotics at 1g/litre of drinking water for broiler production. Further research should be carried out on Alchornea cordifolia and other medicinal plants to examine their potentials and inhibitory characteristics

Survival of Escherichia Coli in Lagos Lagoon

There was a gradual decrease in the population of Escherichia coli incubated in autoclaved and unautoclaved (raw) water samples obtained from three different sampling stations of the Lagos lagoon. The survival period of the bacterium was generally shorter in the unautoclaved than in the autoclaved water sample; and also varied with the season. In November, 1976, the survival periods in unautoclaved (raw) samples were 6 and 8 days respectively; while in February, 1977 they were 12 days for all three water samples. For the autoclaved water samples the survival periods in November 1976 were 12 and 14 days; while in February, 1977 they were 22, 24 and 32 days. The survival period was also affected by seasonal variations in some physic-chemical parameters of the lagoon

Testicular morphology and seminal fluid parameters of adult Wistar rats following honey administration

Purpose: Honey has a long history of use in the traditional medical systems This objective of this study was to find out the effects of honey on quality and quantity of sperm and testicular microstructure when compared to fertility boosting drug and controls.Methods: A total number of thirty (30) matured male Wistar rats that were sexually active weighing 200 - 280g were used for this study. The animals were grouped into five as A - E. Group A was the control; Group B (standard group) was the standard group that received 0.3ml of follicle stimulating hormone (FSH) drug for 6 days; groups C, D and E received 1ml, 2ml, and 2.5ml of honey daily for 21days respectively. After 21 days of administration, the testes were removed for analysis of the sperm parameters and the histology.Results: Honey significantly improved the sperm quality and spermatogenesis rate (denser seminiferous tubule lumen) of exposed animals compared to control animals, but most improvement was seen in the standard group that received 0.3ml FSH. Also no sign of degeneration or cellular loss was observable in the testicular histo-architecture of experimental animals.Conclusion: This research showed that honey possesses some fertility boosting properties in exposed animals compared to controls and honey is not associated with increased sperm abnormalities.Keywords: Honey, Fertility booster, Spermatozoa, Ologospermi

Development and Phenotypic Screening of an Ethyl Methane Sulfonate Mutant Population in Soybean

Soybean is an important oil-producing crop in the Fabaceae family and there are increasing demands for soybean oil and other soybean products. Genetic improvement of soybean is needed to increase its production. In order to provide genetic diversity and resources for identifying important genes, a new ethyl methane sulfonate (EMS) mutagenized soybean population was generated using the newly released germplasm, JTN-5203 (maturity group V). Treatment of soybean seeds with 60 mM EMS concentration was found to be suitable for inducing mutation. A total of 1,820 M1 individuals were produced from 15,000 treated seeds. The resulting M2 population was planted in the field for phenotyping. After harvest, seed traits including total oil, protein, starch, moisture content, fatty acid and amino acid compositions were measured by NIR. Phenotypic variations observed in this population include changes in leaf morphology, plant architecture, seed compositions, and yield. Of most interest, we identified plants with increased amounts of total protein (50% vs. 41% for control) and plants with higher amounts of total oil (25% vs. 21.2% control). Similarly, we identified plants with increases in oleic acid content and decreases in linoleic acid and linolenic acid. This EMS mutant population will be used for further studies including screening for various traits such as amino acid pathways, allergens, phytic acids, and other important soybean agronomic traits. In addition, these mutant individuals will be evaluated in the next generation to assess the heritability. Beneficial traits from these mutants can be exploited for future soybean breeding programs. This germplasm can also be used for discovering novel mutant alleles and for functional gene expression analysis using reverse genetics tools such as TILLING

The Association between Individual and Combined Components of Metabolic Syndrome and Chronic Kidney Disease among African Americans: The Jackson Heart Study

Introduction: Approximately 26.3 million people in the United States have chronic kidney disease and many more are at risk of developing the condition. The association between specific metabolic syndrome components and chronic kidney disease in African American individuals is uncertain. Methods: Baseline data from 4,933 participants of the Jackson Heart Study were analyzed. Logistic regression models were used to estimate the odds and 95% confidence intervals of chronic kidney disease associated with individual components, metabolic syndrome, the number of components, and specific combinations of metabolic syndrome components. Results: Metabolic syndrome was common with a prevalence of 42.0%. Chronic kidney disease was present in 19.4% of participants. The prevalence of metabolic components was high: elevated blood pressure (71.8%), abdominal obesity (65.8%), low fasting high density lipoprotein cholesterol (37.3%), elevated fasting glucose (32.2%) and elevated triglycerides (16.2%). Elevated blood pressure, triglycerides, fasting blood glucose, and abdominal obesity were significantly associated with increased odds of chronic kidney disease. Participants with metabolic syndrome had a 2.22-fold (adjusted odds ratio (AOR) 2.22; 95% CI, 1.78–2.78) increase in the odds of chronic kidney disease compared to participants without metabolic syndrome. The combination of elevated fasting glucose, elevated triglycerides, and abdominal obesity was associated with the highest odds for chronic kidney disease (AOR 25.11; 95% CI, 6.94–90.90). Conclusion: Metabolic syndrome as well as individual or combinations of metabolic syndrome components are independently associated with chronic kidney disease in African American adults

Competency mapping framework for regulating professionally oriented degree programmes in higher education

Recognition of the huge variation between professional graduate degree programmes and employer requirements, especially in the construction industry, necessitated a need for assessing and developing competencies that aligned with professionally oriented programmes. The purpose of this research is to develop a competency mapping framework (CMF) in this case for quantity surveying honours degree programmes. The graduate competency threshold benchmark (GCTB) is a key component of the CMF. Therefore, the CMF contains the mapping process, the template documents and the benchmark. The research adopted literature review, pilot study, case studies (including semi-structured interviews) and expert forum in developing the framework. The framework developed in this research provides new insight into how degree programmes map against competencies. Thus, the framework can be applied more widely, to other professional degree programmes, for monitoring and improving the quality and professional standards of construction degree programmes by accrediting bodies. This should connect construction graduates more effectively to the industry
