Nigerian Companies and the Prohibition on Political Donations: A Paradigmatic Shift as a Panacea for Compliance

Democratic rule is generally acclaimed as a better form of governance, but its operation does not appear to come cheap. This is especially so in Nigeria where new democratic dispensations are heralded by expensive electioneering campaigns. The funds for these campaigns are sourced from willing donors or through subtle coercion. Corporate organizations are easy prey to politicians. This paper is provoked by the frequency and blatancy with which corporate organizations in Nigeria donate to political parties and for political purposes without any sanctions despite the unambiguous prohibition in S.38 (2) of the Companies and Allied Matters Act (CAMA). This exposes the inability of the provision to halt or reduce this practice to the barest minimum and also reveals the unpopularity of the provision. The paper argued that it is not possible to completely extricate organizations from the political dynamics in their host committees and proffered some mitigating factors which will make the provision more acceptable to the people and more respected. The paper discovered normative reasons why the prohibition in S.38 (2) of CAMA is largely ignored.It therefore recommended wide ranging amendments to the provisions so as to enhance compliance, improve its enforcement strategies, reflect present day realities and align it with International best practices

A self-directed learning intervention for radiographers rating mammographic breast density

Purpose: Subjective methods of mammographic breast density (MBD) assessment are prone to inter-reader variability. This work aims to assess the impact of a short self-directed experiential learning intervention on radiographers’ reproducibility of MBD assessment. Method: The study used two sets of images (test and learning intervention) containing left craniocaudal and left mediolateral oblique views. The test set had MBD ratings from VolparaTM and radiologists using the fourth edition Breast Imaging and Data Systems (BI-RADS®). Seven radiographers rated the MBD of the test set before and after a self-directed learning intervention using the percentage descriptors in the fourth edition BI-RADS® Atlas. The inter-reader agreement, agreement between radiographers and VolparaTM as well as radiologist, was assessed using a Weighted Kappa (Kw). Results: Overall, radiographers’ inter-reader agreement (Kw) was substantial (0.79; 95%CI: 0.70–0.87) before the intervention and almost perfect (0.84; 95%CI: 0.77–0.90) after the intervention. Before the intervention, radiographers demonstrated fair agreement with radiologists (0.24; 95%CI:-0.46–0.61) and VolparaTM (0.24; 95% CI: -0.41–0.59). A fair but slightly improved agreement was also observed between radiographers and radiologists (0.31; 95% CI: -0.33 - 0.64) as well as VolparaTM (0.28; 95% CI: -0.34- 0.61) after the intervention. Conclusion: Findings demonstrate that a short duration self-directed experiential learning intervention reduces inter-reader differences in MBD classification, but has a negligible impact on improving the agreement between inexperienced and expert readers

Prevalence of malnutrition among settled pastoral Fulani children in Southwest Nigeria

<p>Abstract</p> <p>Background</p> <p>There is a dearth of information on the health of pastoral Fulani children living in southwestern Nigeria. These are fully settled pastoralists whose economy are centred on cattle and farming. In other to monitor and plan appropriate nutritional intervention for their children, a cross-sectional study was carried out to determine the prevalence of malnutrition of pastoral Fulani children.</p> <p>Findings</p> <p>Fulani's children aged 6 months to 15 years, living in 61 settlements in Kwara, Ogun and Oyo States in Southwestern Nigeria participated in the study. Heights and weights of 164 girls and 167 boys were measured. Their anthropometric indices, height-for-age (HA), weight-for-height (WH), and weight-for-age (WA) Z-scores determined. The prevalence of stunting (HAZ < -2), wasting (WHZ < -2) and underweight (WAZ < -2) was 38.7%, 13.6%, and 38.7%, respectively when compared to the reference NCHS/WHO standard used for defining stunting, wasting and underweight. Boys were more malnourished than the girls were, but this was not significant (stunting: χ²= 0.36; df = 1; P = 0.54); (underweight: χ²= 1.10; df = 1; P = 0.29); and (wasting: χ²= 0.00; df = 1; P = 0.98) The mean of Z-scores of Height-for-age, Weight-for-age and Weight-for-height in children were -1.502, -1.634 and -0.931 respectively. The SD was 1.52, 1.09 and 1.20 respectively. Using WHO Malnutrition Classification systems, 38.7% of the children were found to be malnourished.</p> <p>Conclusion</p> <p>These results indicate high prevalence of malnutrition among settled pastoral Fulani children, possibly due to changes in food habits and lifestyle occasion by the transition from nomadic to sedentary living. We suggest the inclusion of Fulani's settlements in nutritional intervention for these areas.</p

Compressive strength and workability of laterized quarry sand concrete

This paper presents an experimental study on workability and compressive strength of concrete using various combinations of lateritic sand and quarry sand as complete replacement for conventional river sand fine aggregate. Quantity of lateritic sand varied from 0 to 50% against quarry dust at interval of 10%. Concrete cubes were prepared for two mix ratios: 1:1.5:3 and 1:2:4 and three water/cement ratios: 0.5, 0.6 and 0.7 and were cured and tested in the laboratory for compressive strength. Slump tests were also carried out for each mix. For each mix and water/cement ratios, control samples were also prepared using river sand as fine aggregate. The resulting concrete cubes fall within the range for normal weight concrete and although laterized quarry dust concrete had poorer workability, their compressive strength compare favourably with those of conventional concrete. The use of laterized quarry sand concrete for structural members is therefore recommended when laterite content is not more than 50%.Keywords: Compressive Strength, Concrete, Lateritic Sand, Quarry Sand, Workabilit

A Preliminary Survey on the Parasites of Free Range Chicken in Abeokuta, Ogun State, Nigeria

A preliminary study was carried out to assess the parasitic burden of domesticated and free range chicken in Abeokuta, Ogun State, Nigeria. A total of twenty birds where purchased from five popular markets in Abeokuta namely, Itoku, Kuto, Lafenwa and Osiele and examined for presence of parasites. The skin and feathers of the birds were also combed to check for ectoparasites. Afterward, the birds were slaughtered and the intact gastro-intestinal tract were then separated and opened to check for endoparasites. All parasites found were collected into petri-dishes and examined under microscope for identification. Two species of ectoparasites Menacanthus stramineus with a prevalence of 90.0% and Lipeurus caponis with a prevalence of 60.0% were recovered. Three species of endoparasites found consisted of two nematodes (Ascaridia galli and Heterakis gallinarum) and one cestode (Raillietina echinobothridia). Ascaridia galli and Raillietina echinobothridia were seen in the small intestine and Heterakis gallinarum in the caecum.&nbsp; Raillietina echinobothridia had the highest prevalence of 80.0% followed by Ascaridia galli and Heterakis gallinarum each with 60.0% prevalence. The results show that free-range chickens in Abeokuta carry high parasitic burden which could be a big constraint to their productivity and commercial value

Effect of Dietary Pumpkin Stem Waste on Haematological Indices, Meat and Serum Lipid Profiles of Rabbits

This study evaluated the effect of different supplementary dietary levels of pumpkin stem waste (PSW) on the haematological indices, meat and serum lipid profile of rabbits. Three experimental feed regime:D1 (control), basal feed+ 0% PSW; D2,basal feed + 5% PSW and D3, basal feed + 10% PSW were randomly assigned to the three treatment groups in a 3x2 factorial arrangement in a completely randomized design experiment. The PSW percentage were offered on rabbit weight basis. Thirty six (18 males and 18 females) crossbred (California x New Zealand white) weaned rabbits aged 6 and 7 weeks were divided into three treatment groups of 12 rabbits each with 4 rabbits per replicate (2 females and 2 males) and randomly allotted to the three dietary treatments. At the end of 12 weeks feeding trial( prior to slaughtering), blood samples were collected from 6 rabbits (3 males and 3 females) per treatment totalling 18 rabbits and used to determine the serum lipid profile and haematological blood indices. Similarly, breast meat sample was used to determined lipid profile. Results obtained showed that while red blood cell (RBC),haemoglobin (Hb), packed cell volume (PCV),Mean cell haemoglobin (MCH) and mean cell haemoglobin concentration MCHC increased (P&lt;0.05) with increasing dietary PSW. White blood cell (WBC) and MCHC however showed no significant difference (P&gt;0.05) among the treatments groups. Lipid profile of both serum and meat indicated that HDL increased significantly (P&lt;0.05) with increase in PSW while total cholesterol (TC), low density lipoprotein (LDL), triglyceride (TG) and very low density lipoprotein (VLDL) decreased significantly (P&lt;0.05). Diet by sex interaction showed that male rabbits recorded significantly different (P&lt;0.05) values from their female counterparts in all the blood and meat lipid parameters assessed. These results suggest that pumpkin stem waste is hypolipidaemic therefore could lower rabbits’ meat cholesterol and improve blood constituents

Evaluation of Public-Health Risk of Heavy Metals Contaminants and Physicochemical Parameters in Adulteration Palm Oil Commonly Consumed in Calabar, Nigeria

Edible palm oil has been the parity of the human diet from generation to generation and has contributed both to nutrition and health. These studies investigated some selected heavy metals and physicochemical parameters in palm oil. Eleven (11) samples of ready-consumed edible palm oil were bought randomly from the selected market in calabar metropolis. The samples were digested with 25ml of concentrated H2SO4, for heavy metals analysis using Atomic Absorption Spectrophotometer (AAS). The physiochemical parameters in selected markets include the following FFA, IV, PV, and protein content were also analyzed using standard methods. The results showed that FFA value range from 9.26 to 12%, Iodine value range from 45.78 to 21.40 MgKOH/g, Peroxide value range from 3.60 to 0.03 Meq/kg, and protein content ranges from 0.06 to 0.2 mg were significantly (p&lt;0.05) higher in some markets in comparison to the control. The results of heavy metals showed that Zn 8.06±0.06, Cd 1.01±0.05, N 1.00±0.00, C 125.91±0.09, Pb 9.30±0.07 Cobalt, Lead zinc were above the detectable limit of the WHO standard while Cd and Ni were within the permissibility limit. The results obtained from this study indicate that the palm oil sold in calabar metropolis may cause a public health risk if proper monitoring is not maintained by regulatory agencies. Thus, there is a need for improved screening of our local processed palm oil from the time of production to the time of consumption

Phytochemical and comparative antidiabetic studies of leaf extracts of Viscum album from different plant hosts

Phytochemical screening and evaluation of antidiabetic activity of leaf extracts of Viscum album from four different plant hosts were carried out using standard procedures. The results of the phytochemical screening revealed that the different leaf extracts vary in their phytochemical constituents depending on the plant host. Moreso, all the leaf extracts of Viscum album demonstrated significant (p&lt;0.001) lowering of blood glucose level (BGL) in alloxan-induced diabetic rats. The leaf extract of V. album from Dennettia tripetala exhibited the highest antidiabetic activity than the other extracts followed by Citrus sinensis and Pisium guajava and their activities were more pronounced than that of standard drug, glibenclamide during acute study. On prolonged treatment, Viscum album leaf extracts from C. sinensis (VAC ) and P. guajava (VAP) had comparably higher antidiabetic effects than the other extracts and glibenclamide. These were followed by that from Dacroydes edulis (VAD) while Dennettia tripetala (VADT) had the lowest antidiabetic effect. Although V. album possesses antidiabetic property, its antidiabetic efficacy depends on its phytochemical constituents which in turn depends on the plant host.Keywords: Mistletoe, Hyperglycemia, Alloxan, Glibenclamid
