- Cervical cancer is a major reproductive health problem among women in Nigeria, every woman who has ever been sexually active is at risk. Certain factors also increase the risk of developing the disease. Cervical cancer can usually be found early by having regular Pap smear tests but this test is rarely provided and hardly utilised by women. This study was aimed at finding out the level of awareness of female health workers and the level of utilization of pap smear testing. The study was carried out using descriptive survey research design and the total population of 623 health workers in government owned hospitals were used as respondents for the study. Only 502 of the structured questionnaire were returned. Reliability of the instrument was determined using a test-retest method with Pearson Product Moment correlation and it yielded reliability co-efficient of 0.73. Data collected was analysed using descriptive statistics of frequency count and percentage for the research question, while inferential statistics of chi-square and regression were used to determine the level and the direction of relationship between the independent and the dependent. The level of significance was set at p-value <0.05. The results shows that only 118 (23.5%) have had pap smear test while 384 (76.5%) have not. Also, awareness of cervical cancer risk factors was significant (X2cal 33.426, X2crit =11.071, df= 5, p< 0.05) among health workers. But, this awareness of the risk factors did not significantly influence (13 =.084, t= 1.069, p> 0.05) the utilization of pap-smear testing among female health workers in Ibadan. It is surprising to note that the awareness of cervical cancer risk factors did not influence the utilization of pap- smear testing among health workers in Ibadan. In recommendation, female health workers should be sensitised and encouraged to subject themselves to pap-smear testing as the experience will serve as a source of empowerment in their pivotal role of adviser and developing consciousness, reliance and cooperation of other women. 2 results 2

- The influx of massive revenues during periods of abnormally high oil prices creates enormous challenges for policy-makers in oil-producing countries. In Nigeria, the prudent utilisation of oil revenues has remained elusive for policy-makers over time. While the country has earned sizeable oil revenues from its natural endowment, poverty and income inequality have been persistent. This study tests the sensitivity of several important macroeconomic indicators to oil revenue shocks. We additionally test for the effect of ‘institutional quality’, in recognition of the important role played by the domestic institutional context in shaping the policy responses adopted by successive Nigerian governments to oil windfalls over time. The sensitivity analysis supports the general view that fluctuations in oil revenues have resulted in inflation, lower output growth and real exchange rate appreciation in Nigeria. More importantly, the aforementioned institutional variable is found to be very significant. This finding is consistent with the general assessment of fiscal performance in Nigeria during oil windfalls as being driven by domestic institutional dynamics. Ostentatious public consumption widened fiscal deficits, and government spending has been highly pro-cyclical during windfall episodes. In conclusion, the study offers appropriate policy recommendations, which could be adopted to enhance the management of future oil windfalls in Nigeria. 2 results 2

- A considerable fraction of sand in Niger Delta Area of Nigeria is contaminated with crude oil. The contaminated sand is largely utilised by local contractors for the production of concrete. However, there is need to establish its suitability in concreting. Previous works have centered on hardened uncontaminated concrete in crude oil environment but not on concrete made with Crude Oil Contaminated Sand (COCS). This research was designed to evaluate the effect of COCS on some engineering properties of fresh and hardened COCS concrete. Levels of crude oil contamination were determined using gravimetry method of Total Petroleum Hydrocarbon (TPH) test on nine sand samples randomly collected from some oil spill sites in Rivers State. Based on the test results, seven types of artificially contaminated sand were prepared with crude oil levels of 0.0, 2.5, 5.0, 10.0, 15.0, 20.0 and 25.0%. Workability (slump, compacting factor and flow), compressive strength, linear shrinkage, water absorption, and fire resistance were determined using concrete cubes, flexural strength using concrete beams, and surface resistivity using concrete cylinders in accordance with standard methods. Data obtained were analysed using ANOVA at p = 0.05. Eight models were developed using historic response surface methodology to predict the engineering properties of COCS concrete at water-cement ratio (w/c) of 0.5. Also, COCS concrete design mixes with contamination level and w/c ratio suitable for reinforced concrete were formulated. The TPH varied from 8.6 ± 0.2 to 14.1 ± 1.3%. The workability of concrete was improved by the presence of COCS. Slump, compacting factor and flow of the fresh concrete increased with increase in contamination from 30.0 to 200.0 mm, 0.5 to 0.9 and 15.0 to 85.0%, respectively. Compressive strength, flexural strength, linear shrinkage and water absorption of the hardened concrete reduced with levels of contamination from 31.5 ± 2.3 to 3.5 ± 0.0 N/mm2, 5.9 ± 0.8 to 0.1 ± 0.0 N/mm2, 0.1 ± 0.0 to 0.0 cm and 0.2 to 0.0 kg respectively. At a temperature of 200.0˚C, the percentage strength reduction increased from 18.4 to 94.8% for 2.5 to 25.0% contamination. Surface resistivity ranged from 25.1 ± 0.2 to 32.3 ± 0.2 kΩ-cm. The compressive and flexural strengths of COCS concrete were reduced by more than 50.0% at crude oil contamination level greater than 10.0%. The water absorption and surface resistivity values indicated that COCS concrete exhibited greater resistance to water and chloride penetration respectively, it shrank less when compared with the uncontaminated concrete, but exhibited poor fire resistance. Coefficient of determination, R2, of the models developed ranged from 0.823 to 0.999. Concrete design mix ratio of 1part of cement to1.6 part of COCS (10.0% crude oil) to 2.4 part of coarse aggregate was found to be appropriate at 0.45 w/c. This mix gave minimum compressive strength of 21.0 N/mm2 which is acceptable for reinforced concrete structures. Concretes produced with sand contaminated with less than ten percent crude oil were found suitable for use in low strength structures. Mix re-design using lower w/c improved the strength of the concrete. 1 results 1
- A student’s abilitiy to read and understand written texts is one of the fundamental skills that enable students to succeed in his academics. However, far many students in Nigerian schools with learning disabilities reading comprehension is the major deficiency. This study, investigated the effectiveness of the Directed Reading Thinking Activity (DRTA) in improving reading comprehension of secondary students with learning disabilities. The study employed a pre-test, post-test, control group, quasi-experimental research design. The design utilised a 2x2x2 factorial layout. Simple random sampling technique was used to select One Hundred (100) Junior Secondary Class 2 from two junior public schools. The presence of different levels (ranging from mild to severe) of learning disabilities was the major criterion far this selection. Screening was conducted with the Myklebust Rating Scale (r = 0.76). Participants in the experimental group were exposed to five weeks of reading comprehension training using the directed reading thinking activity strategy. The control group was not treated. Three null hypotheses were formulated, while data collected were analysed using t-test statistics. The results showed that participants exposed to the directed reading thinking activity strategy performed better than their counterparts in the control group. Thus, since the directed reading thinking activity strategy was found to be superior to the conventional method. 1 results 1

- Achieving food security under climate change is one of the greatest concerns of governments in developing countries. Due to favourable agronomic characteristics such as drought tolerance and an ability to produce a crop on less fertile soils, a number of under-utilised crops, such as bambara groundnut offer potentials to address food insecurity problems in areas impacted by climate change. While efficiency studies have gained popularity in relation to many food crops, very little research has been carried out on the technical efficiency of bambara groundnut production. This study estimated a Translog stochastic frontier to determine the factors that influenced farmers’ technical efficiency in the 2013 cropping season in Northern Ghana. It involved 120 farmers selected through a multi-stage sampling technique. Technical efficiency scores ranged from 27% to 97% with a mean of 83%. The significant positive determinants of output and efficiency were farm size, household labour, organic fertilisers as well as education and off-farm activities. The study found that bambara groundnut production can be stepped up by supporting farmers to scale up their farms, form farmer groups, diversify their livelihoods and improve the use of organic fertilizers. Improving opportunities for formal education may also have a positive impact. 1 results 1
