- Research on sexual violence is fraught with ethical and methodological challenges due to its sensitive nature. This paper describes the ethical and methodological challenges encountered in planning and conducting two exploratory studies on sexual violence that included in-depth interviews of eight female adolescent rape survivors in Ibadan and four married women in Lagos Nigeria who were raped, forced to perform sexual acts and sexually deprived. The first challenge encountered was an Institutional Review Board (IRB) requirement to obtain parental permission from adolescents, when such a requirement may place the adolescent at risk if a parent was a perpetrator of sexual violence. Using arguments emphasizing the Council for International Organization for Medical Sciences guidelines helped convince the IRB to provide a waiver of parental consent. Second, the privacy required to conduct in-depth interviews for rape survivors was difficult to achieve because five of the rape survivors were apprentices who work in public settings that which are typically used to conduct business In the informal sector. To overcome this challenge, interviews were conducted in safe locations, investigator's offices and homes of survivors. The culture of silence associated with sexual violence posed a challenge because it encourages perpetration of violence with impunity causing rape survivors to suffer in silence. None of the affected adolescents had sought judicial redress for rape despite availability of stringent punishment for this behaviour. Referral information was provided on where survivors could seek care. Interviews with the women could not be recorded on audio-tapes because of concerns that their partners might identify their voices from the tapes and punish them for this. Although research on sexual violence poses ethical and methodological challenges, it is not only desirable but also feasible to conduct such research in ways that ensure safety of participants. 2 results 2
- " The Aluminium Smelting Company, located in Ikot Abasi area, lies within the dominantly clastic rocks of the Benin Formation of the eastern Niger Delta. In order to evaluate the level of environmental contamination associated with this major industrial project, concentrations of trace elements and major elements in representative samples of soil, stream sediments and water in the vicinity of the industrial complex were determined by ICP-OES (for soil and stream sediments) and Atomic Absorption Spectrophotometer (AAS) (for water). Samples from a control site, about 3km from the complex were also collected and analyzed for the same set of elements, Results revealed that concentrations of all the elements in the sampled materials were within background levels in comparison with those from the control site. The trace and major element variations show some slight decreasing concentration with increase distance from the factory site for mostly Pb, Zn Cu, Ni for the trace elements and Ca for the major element. There is no significant variation in the soil profile with depth for the elements. Generally, concentration of elements is in the order: Zn>Pb>Ni>Cu and Fe>Al>Ca>Mg>Na>K for the trace and major elements respectively. Computation of geo-accumulation index for the soils revealed no secondary enrichment. Application of R-mode factor analysis shows four groupings, reflecting lithological and environmental controls. The stream sediments show generally low concentrations that fall within the concentration range of sediments of similar provenance elsewhere. Metal concentration levels in the water show higher values for the surface water. Both hydrophysical and chemical parameters have slight elevated values when compared with the control and reflect a dominant geogenic source. Generally, they lie within the ambits of the World Health Organization (WHO) Standards of water quality and pose no threat to aquatic or human community. " 1 results 1
- "Subsurface samples from the Akinside 1582 well, located within the eastern Dahomey Basin were evaluated to determine the lithofacies, depositional environment, and hydrocarbon potential of the basin. The sediments within the interval 138-197m consist of limestones, shales, mudstone and glauconite; thus representing sediments belonging to the Ewekoro and Akinbo Formations. The limestones are greyish, highly indurated, partly recrystallised and reveal six microfacies notably biosparite, shelly biomicrite, biomicrite, pel-biosparite, sandy-pelmicrite and sandy-biomicrite. The presence of gastropods, pelecypods, echinoderm, coralline algae, foraminifera and other skeletal debris indicate a shallow marine environment of deposition for the limestone. Total organic carbon (TOC) for the sediments range from 0.10 to 0.58wt% and 0.59 to 0.62wt% for the Ewekoro and Akinbo Formations respectively while soluble organic matter (SOM) are correspondingly 392ppm and 887 to 2472ppm. These suggest a poor through moderate to adequate organic matter. Plot of HI versus Ol indicates Type III and IV kerogens. Tmax value range from 362 to 467°C and cross plot of HI versus Tmax points to mainly immature to early mature sediments. The terpanes and sterane distributions indicate a marginally mature status for the sediments. Pristane/phytane ratio ranges from 0.13 to 0.24 and 1.88 for the Akinbo and Ewekoro Formations respectively, thus indicating both anoxic and oxic conditions of deposition. The abundance of pentacyclic triterpane of oleanane and hopane skeletons and C27 to C29 regular steranes in the bitumen, indicate mixed source rocks (marine and terrestrial) for the sediments. However, ternary plot of C27, C29 and C29 steranes strongly amplify terrestrial organic matter with prospect to generate gas rather than oil in the basin at appropriate maturation. " 1 results 1
- "Subsurface samples of Mamu Formation from Ezimo 1235 and Enugu 1327 wells, located within the Anambra Basin were examined for organic geochemical characterization and biomarker content in order to determine the lithofacies association, hydrocarbon potential as well as the palaeodepositional environment. The sediments are made up of siltstone, dark coal, highly fissile shale and mudstone. Selected samples, made up of shale and coal from both wells were subjected to Rock Eval and gas chromatography/mass spectrometry (GC-MS) analyses. Results of the Total Organic Carbon (TOC) ranges from 5.15 to 69.56wt%, Soluble Organic Matter (SOM) values ranges from 286 to 1700ppm while the Generative Potential (GP) ranges from 10.02 to 311.86kgHC/t. These values suggest that the source rocks are moderately to fairly rich in organic matter. Hydrogen Index (HI) values range from 95-381 mgHC/gTOC and indicate types II and III kerogen. Cross plots of HI against OI signify types II and III kerogen which also indicate oil and gas prone source rocks. Tmax values of 422-437oC and Bitumen Ratio of 6.34 to 101.1 mg ext/gTOC signify low maturation level for the source rock. Ratios of C29 hopane βα/ αβ, C30 βα/αβ, and 22S/22S+22R C32 hopane range from 0.32 to 1.18; 0.21 to 0.57; and 0.13 to 0.52 respectively, and suggest immature organic matter status. Carbon Preference Index (CPI) value ranges from 1.33 to 1.97 suggests immature source rock of terrestrial origin. High values obtained from the C24 tetracyclic/C24 tricyclic terpanes and the C19/ C20 tricyclic terpane ratios, (1.52-2.64) and (0.54- 1.54) respectively, also portray terrigenous organic matter contribution. The presence of C27 to C29 steranes and diasteranes, signify mixed sources (marine and terrigenous) with prospects to generate both oil and gas; however, the dominance of C29 over C28 and C27 amplify higher contribution of terrigenous materials. The terrigenous input is further amplified by the Pr/Ph ratio ranging from 5.44 to 7.81. Cross plots of Pr/nC17 against Ph/nC18 also denote terrigenous sourced organic matter deposited in oxidizing environment. The high ratio of C30/C29Ts, indicates source rocks deposited under suboxic conditions. It can be deduced that the sediments are immature, and were deposited in a suboxic, low Eh environment. They are potential source rocks which are moderately to fairly rich in organic input with substantial amount of terrestrial organic matter, having prospects to generate gas at appropriate maturation.

- "The quality as well as the quantity of clean water supply is of vital significance to the welfare of mankind particularly in the developing countries. Therefore, knowing the concentration of heavy metals present in Dams can help us to ascertain the health safety of the populace using the water for drinking and domestic purposes. Ten Dams at Oyo State in the Southwestern Nigeria were studied for the heavy metals concentration contained in the sediments and water of the selected Dams. Bottom sediments and water were collected from the selected dams for analysis. Analysis of both the water and sediments to determine the concentration of each heavy metal was evaluated. The result obtained shows that, the concentration of Manganese (Mn) ranges from 14.8 mg/kg to 332.96 mg/kg followed by Zinc (Zn) which ranges between 6.18 mg/kg and 52.53 mg/kg which spread across all locations., Lead (Pb) was not detected in virtually all the locations except in Ilora which has a concentration of 0.87 mg/kg and this may be as a result of the activities of motor mechanics and vulcanizers around the dam. In the water samples, the result showed that the concentration of heavy metals is very low which is far below the limit specified by World Health Organization (WHO). Zn has the highest concentration ranging from 0.049mg/kg to 0.729mg/kg, followed by Mn which has concentration between 0.011mg/kg and 0.344mg/kg. Pb, Cadmium (Cd) and Cobalt (Co) were not detected at all in all the water samples. The variation in the concentrations may be due to geological nature of the ground, solubility, an ion exchange and human activities. " 1 results 1
- A double burden of malnutrition occurs when individuals, household members or communities experience both undernutrition and overweight. Here, we show geospatial estimates of overweight and wasting prevalence among children under 5 years of age in 105 low- and middle-income countries (LMICs) from 2000 to 2017 and aggregate these to policy-relevant administrative units. Wasting decreased overall across LMICs between 2000 and 2017, from 8.4% (62.3 (55.1–70.8) million) to 6.4% (58.3 (47.6–70.7) million), but is predicted to remain above the World Health Organization’s Global Nutrition Target of <5% in over half of LMICs by 2025. Prevalence of overweight increased from 5.2% (30 (22.8–38.5) million) in 2000 to 6.0% (55.5 (44.8–67.9) million) children aged under 5 years in 2017. Areas most affected by double burden of malnutrition were located in Indonesia, Thailand, southeastern China, Botswana, Cameroon and central Nigeria. Our estimates provide a new perspective to researchers, policy makers and public health agencies in their efforts to address this global childhood syndemic. 1 results 1
- A fluviatile ecosystem, River Ogunpa, was studied between the months of May and July 2000, to assess spatial variations in physical and chemical parameters and benthic macro-invertebrate faunal composition. Water and qualitative benthic samples were collected four times from five stations located along the river for laboratory analysis. High mean value of biochemical oxygen demand (BOD) of 20.15 ± 4.18 mgO2/l, chemical oxygen demand (COD) of 121.95 ± 19.04 mg02/l ammonia of 1.53 ± 0.44mg/l, total suspended solids (TSS) of 152.2+12.85mg/l, lead of 0.126 ± 0.06mg/l, copper of 0.3+0.07mg/l and zinc of 0.49 ± 0.07mg/l were recorded. Analysis of variance (ANOVA) showed significant differences (P<0.05) in mean values of pH, dissolved oxygen (DO), COD, turbidity, iron and copper from the five stations. Six benthic macroinvertebrate fauna; Melanoides tuberculata, Physa waterloti, Bulinus globosus, Tubifex spp; Chironomus spp and Brachydeutera spp. were recorded. The result showed that the river is under pollutional stress from oxygen demanding organic wastes. Heavy metals analyzed show that lead, copper and zinc levels may be increasing to dangerous levels in the river. Spatial variations along the river showed some stations to be more polluted than others. All the benthic macro-invertebrate fauna recorded were pollution tolerant species. 1 results 1
- A study was carried out to determine the physico-chemical characteristics and heavy metal contents of the water and sediment of Ekole river in Bayelsa state, Nigeria. Water and sediment samples were collected in the dry (december/ January) and wet (June/July) seasons during 2003 and 2004. Surface water up to 15cm depth and sediments were sampled at nine locations: 100, 200, 400, 500m upstream; 0, 100, 200, 300, 400m downstream of an oil flow station. The samples were anlyzed for total suspended solids (TSS), pH, chloride, dissolved oxygen, conductivity and heavy metals. These parameters were either measured in-situ using approriate meters or analysed in the laboratory using standard methods. The results obtained were compared with the baseline ecological data for 'Gbaran Extended Field'. upstream of the study of the area. World Health Organization and the Federal Environment Protection Agency's standards for water quality. The results showed increase TSS. pH and conductivity of the water over the baseline data. All heavy metals of interest: cadmium(Cd), lead (Pb), mangaese (Mn) zinc(Zn), nickel(Ni) copper, (Cu), iron (Fe) and chromium (Cr) were present in the water while Ni, Cd and Cr, absent in the baseline data were detected. Significant increases (p<0.05) were recorded for iron, zinc, copper and managese over baseline data. Higher concerntrations (p<0.05) of heavy metals were recorded in sediments than water and the dominant metal was iron. It was concluded that changes in water quality had occured in Ekole river near Obama flow station and the need to adhere to existing environmental laws and regular monitoring recommended. 1 results 1

- As part of the Millennium Cities initiative, organized by Earth Institute of Columbia University USA, Akure, Nigeria was selected as one of the cities in Sub-Saharan Africa to be assisted in achieving the millennium development goals (MDGs). Other cities selected in Sub-Saharan Africa include Kisumu. (Kenya); Blantvre. (Malawi); Kumasi, (Ghana); Bamako. (Mali); Sezou, (Mali); Kaduna, (Nigeria) and Mekelle. (Ethiopia). It is necessary to point out that this initiative focuses more on inter-governmental actions than tackling the source of the developmental problem of the cities involved in the initiative. Using a mixed methodological approach, which included participant observation and structured interviews by means of convenience and snowball sampling methods administered in the study area. According to the aim of the project it is to promote investment from overseas (capitalist) companies, create employment and help in the domestic affairs of the cities involved. This paper examine the impact of the MDGs on the built environment and critique these ‘lofty ideas' which has failed to address the local, regional and cultural specificity of the location; and which has not been productive in Sub-Saharan Africa. The paper concludes that the desire for an integrated city cannot be 1 results 1
- Assessment is highly fundamental to teaching-learning process, because it reveals the learning difficulty of learners among others. Past research works reported variations in assessment effecti veness of the teachers which could be as a result of influence of some teacher-based factors. This study therefore investigated the predictive strengths of Bandura five-factor self efficacy and demographic factors on teachers' Assessment Effectiveness in mathematics-related subject. The study adopted a correlational design. The sample of the study consisted of 225 Junior Secondary mathematics-related subject teachers, selected using Stratified random sampling technique from the 3 Senatorial districts in Ogun State. Teacher Self-Efficacy Scale developed by Bandura (r= 0.89) and Teacher Assessment Effectiveness (r=.60) were used to collect data for the study. Descriptive statistics (frequencies and percentages), and linear multiple regression analyses were adopted for the analysis of the collected data. The results show that only test, homework/assignment, class work and observation of class participation were assessment tools commonly used by the teachers. The results also showed that, the predictor variables:Bandura five-scale teacher self efficacy and demographic factors explained the 9.9 per cent of the varjance in assessment effectiveness. Howeverfactors explained the 9.9 per cent of the varjance in assessment effectiveness. However among thdnine predictors, only Instructional Self Efficacy (B=0.035; t=2.136; p<0.05) and efficacy to enlist community involvement (B=0.046; t=2.369; p<0.05) were found to be significant predictors to teachers' Assessment Effectiveness. Based on the findings, it was therefore recommended that the training that would boost instructional self efficacy should be organized by the rapport between town gown, by establishing community- based school management committe to facilitate relationship between a school and the community where it is located . 1 results 1

- BACKGROUND: Meningiomas are the second commonest intracranial tumors in many places worldwide. They are rare in the pediatric age group, however, and most studies have been able to document only a few patients. Meningiomas in pediatric patients have also been shown to behave differently from those in the adult population. This study was done to examine histologic types of meningiomas seen in pediatric patients from a predominantly African population using the 2016 World Health Organization (WHO) grading system for intracranial tumors. METHODS: Data from the operating logs of patients and histology reports of the samples sent to the pathology department during the study period were extracted. The data obtained were the age, sex, location of the intracranial tumor, histologic diagnosis, WHO grade, and tumor recurrence. RESULTS: Nine pediatric age patients were found among the 166 surgically excised meningiomas received at the pathology department in our institution over a 19-year period. The age range was from 8 months to 17 years. There was a male-to-female ratio of 1:2 with a female predominance. Six tumors were basally located. All tumors were WHO grade I, with transitional meningiomas being the commonest, followed by meningothelial. There was no history of recurrence in any of the tumors after complete surgical excisions. CONCLUSIONS: Our study showed the rarity of meningiomas in the study population, and there was a predominance of basally located tumors. 1 results 1
- Background. Vocational skill acquisition constitutes an important component of the educational process of training both young and old adults including out-of-school children. The purpose of this study was to assess the extent to which vocational skill acquisition training programme impacted the lives of beneficiaries taking into consideration the influence of socio-cultural and environmental factors on peoples’ participation in vocational skill acquisition training programmes in Ibadan Metropolis of Southwestern Nigeria. A descriptive cross-sectional study was conducted among 220 learners aged 11–50 years with at least two years of learning experience. Data were collected with a questionnaire and analyzed using frequency counts, percentages and chi-square analysis. Results. The results indicate that the majority of participants 41.3% (n=83) possesses National Diploma were unemployed youth graduates while 27.4% (n=55) possesses secondary education were out-of-school youth. A significant proportion of the age group 21 to 30 years constitutes the largest 65.7% (n=132) participated in vocational skill acquisition training programmes. The three socio-cultural important factors predicting peoples’ participation in skill acquisition training were cultural value system, social networks (family, friends and relatives) and customs and tradition disposition to vocational training programme. Again, the results also revealed that the three main environmental factors that influence learners’ participation in skill acquisition training were home environment (location of the training centres), society success stories on vocational skill acquisition and overemphasizing on skill acquisition to complement formal schooling. The main challenges facing learners to engage in vocation skill acquisition training programme were lack of motivation from the society, lack of modern machines and tools to work with after graduation, limited availability of industries for employment after graduation, limited opportunities for establishment after graduation and poor government policies on vocational skill acquisition programme. Conclusions. The out-of-school youths and unemployed youth graduates who participated in the study are willingly enrolled in vocational skill acquisition training programme based on the socio-cultural and environmental factors with the intention to acquired one skill or the other to be self-reliance. Having identified the importance of socio-cultural and environmental factors on peoples’ participation in vocational skill acquisition training programme will enable government put into consideration these factors in planning, organizing and implementing their vocational skill acquisition training programme in order to achieve desirable results on the citizenries. However, there are critical perceived barriers that need to be addressed, to enable more out-of-school youths and unemployed youth graduates with the desire to participate in vocational skill acquisition training programme to reduce unemployment rate in the country. 1 results 1
