Teacher Attitude and Student Performance in Indigenous Language Learning in Lagos

When the Federal Government of Nigeria in 1987 introduced the educational policy that required study of one of the three national languages, i.e., Hausa, Igbo and Yorùbá, at the West African School Certificate / General Certificate in Education [WASC / GCE] level, Nigerians and especially advocates for the survival of the indigenous languages embraced the idea with great enthusiasm. The primary aim was to make more Nigerians speak indigenous languages in addition to the language of their immediate environment. However, this purpose was frustrated when students opted for, and indeed registered for, their mother tongues rather than a non-familiar indigenous language. If the policy had been actually followed, the country would have generated citizens, who not only speak their own indigenous languages, but also citizens who have a practical knowledge of all of their country’s traditional languages. But this did not happen. In this paper, we look at the attitudes of private school teachers to the teaching of the indigenous languages vis-a-vis the competence and performance of students in these indigenous languages. The study is not only comparative but also correlative. The methodological instruments included a questionnaire, interview, a quasi-test and examination of junior / senior secondary school leaving certificates. Our findings revealed that students’ performances, as reflected in their results, do not demonstrate their competence in the indigenous languages in question. Similarly, we observed that both the teachers and the learners are instrumentally and not integratively motivate

Farmers Utilization of Farm - Radio Programmed for Marketing of Agricultural Commodities in Oyo State, Nigeria

Radio can persuade and effectively influence large audience, thereby contributing substantially to the building of national consensus. It is a powerful instrument in the area of public enlightenment, on health issues, family planning, cultural reawakening, and marketing of agricultural products, business improvement and other social issues. The study examined the used of radio for the marketing of agricultural products in Oyo State, Nigeria. A random sampling technique was used to select one hundred and fifty (150) farmers for the study. The results of the findings showed that majority of the respondents (66.7%) were women with most of them between 41-50years of age. Majority of the respondents were married (67.3%) and educated (72.0%), which has positive effect on their use of marketing information. Farming constitutes the major occupation (81.3%) of the respondents, with many of them (68.0%) having between 6-15years farming experience. The result further shows that majority of the farmers (84.0%) used the radio agricultural programme as their agricultural market information source. Inferential statistics results indicate that there were significant relationship between farmers use of farm-radio programme for marketing agricultural commodities and educational attainment (X2 = 16.35; < 0.05) and primary occupation (X2 = 61.25; < 0.05). However age (X2 = 5.54; > 0.05) and marital status (X2 = 10.46; > 0.05) among other variables had no significant relationship with the use of farm-radio programme for marketing agricultural commodities. Also the results on farmers awareness (r = 0.632, p < 0.05) and use of farm-radio for marketing agricultural commodities had a positive relationship while constraints (r = -0.0256, p < 0.05) had a negative relationship with farmers use of farm-radio for marketing agricultural commodities. The study concluded that apart from radio, the mostly widely use source of market information by farmers are extension agents and verbal contact with fellow farmers.

Assessment of Urban Infrastructure Quality and User Satisfaction in Low Income Residential Neighbourhoods in Minna, Nigeria

This study assessed urban infrastructure quality and the level of user satisfaction with urban infrastructure in low income residential neighbourhoods in Minna, Nigeria. Five (5) neighbourhoods were selected for the study, and a total of 250 housing units were sampled. Questionnaire was administered on households that fell within the sample and used to retrieve relevant data. This was followed with an observatory study of the entire study area. Simple descriptive statistic, frequency distribution, Kruskal wallis (H) test, Pearson's correlation, and Relative satisfaction index (RSI) were used to analyse collected data at different levels in the research. Analyse-it ® v4.5 statistical software for Microsoft excel was used to carry out all statistical analysis. Seven (7) components of urban infrastructure were identified to sustain residential properties in the study area and the varied conditions of each of these infrastructure was presented. The overall quality of urban infrastructure was established based on cumulative weighted scores of respondents rating of urban infrastructure quality in their respective neighbourhoods. Total weighted scores of 600 and below signified a general poor quality of urban infrastructure in the affected areas. A correlation coefficient of 0.853 indicates a strong positive relationship between drainage conditions and the condition of access roads, among others, while low RSI for access roads (1.972), drainage systems (1.456), waste disposal (1.712), security (2.632), water supply (1.372), electricity supply (1.52), and neighbourhood cleanliness (1.688) indicate a very low level of user satisfaction with urban infrastructure in the study area. Over 50% of respondents described the management of urban infrastructure in their neighbourhoods as being poor. The study recommend that efforts by the concerned authorities should be intensified towards the provision and proper management of urban infrastructure in urban areas.Keywords: Infrastructure quality, residential neighbourhood, urban infrastructure, usersatisfactio

Spatial variability of solar quiet fields along 96° magnetic meridian in Africa:results from MAGDAS

We have used chains of Magnetic Data Acquisition System (MAGDAS) magnetometer records of the horizontal (H) and vertical (Z) magnetic field intensities during September 2008 to August 2009 (year of deep minimum) across Africa to study their variability during the quietest international days, which coincidently associated with the sudden stratospheric warming (SSW) event in January 2009. This selection of the most international quiet days is indicative of 80% that are strongly associated with days when unusually strong and prolonged sudden SSW event occurs in January 2009. Interestingly, in January, a significant magnitude depletion of solar quiet (Sq) equivalent current was observed near noon hours around the magnetic equator (Addis Ababa, ABB) compared to any other months along with a consistent significantly reduced value across the Northern Hemisphere and moderate decrease at the Southern Hemisphere. Also, we found that Nairobi and Dar es Salaam at the Southern Hemisphere, which are close to ABB (dip equator), are strongly prone to westward electric field compared to the magnetic equator and Khartoum at the Northern Hemisphere. Significant negative values of MSq(Z) magnitudes observed near noon hours at Hermanus indicate the presence of induced currents that suggest ocean effects along with reversal to significant positive values in the afternoon, which subsided before 1800 LT in almost all the months, indicate stronger influence of ionospheric currents. On seasonal variability of Sq(H), a slight depression at ABB during September equinox is one of the evidences of seasonal Sq focus shift. Latitudinal variability of Sq near-noon hours was also investigated

Short CommunicationAttitude of Infertile Women to Child Adoption in Nigeria

Infertility has serious consequences especially in Africa where a high premium is place on child bearing. An interviewer-administered questionnaire was administered on 396 consenting women seeking infertility treatment at the gynaecological clinic of the University College Hospital, Ibadan in an attempt to assess the attitude of infertile women in Nigeria to child adoption and its acceptability as a management option for infertility. Most (64%) believed its culturally unacceptable and only 17% will try it as an option. Sustained advocacy, community mobilization and enactment of supportive laws were some of the suggestions made by respondents to improve its uptake.Keywords; Infertility, Adoption, Assisted ConceptionNig.

Microbial Water Quality Assessment of Packaged Drinking Water of Pre-School Children in some Parts of Accra

Episodes of Cholera outbreaks are still common in most developing countries and children usually are at the greatest risk. This study assessed the importance of diarrhoea-related illnesses among children five years of age or less at the University Hospital, Legon and the importance of packaged water handling in the contamination of drinking water of pre-school children. Diarrhea-related diseases (DRD) accounted for 6.3% of cases involving children five years and below reporting at the University Hospital, Legon during the period of the study. Generally, greater number of cases (DRD) were reported among males (6.9%) than among females (5.6%). High counts above recommended levels of either Total Heterotrophic Bacteria, Pseudomonas or Total Coliforms were observed in 88% of the water samples tested. Inadequate cleaning of water bottles and in some instances the use of inappropriate water bottles (reusing PET mineral water containers) contributed to the poor quality of the drinking water of the preschool children. A greater part of the contamination of the drinking water occurred at home and not at the schools. Parents therefore need to be targeted with water, sanitation and hygiene related health education

Acoustic Events in the Solar Atmosphere from Hinode/SOT NFI observations

We investigate the properties of acoustic events (AEs), defined as spatially concentrated and short duration energy flux, in the quiet sun using observations of a 2D field of view (FOV) with high spatial and temporal resolution provided by the Solar Optical Telescope (SOT) onboard \textit{Hinode}. Line profiles of Fe \textsc{i} 557.6 nm were recorded by the Narrow band Filter Imager (NFI) on a $82" \times 82"$ FOV during 75 min with a time step of 28.75 s and 0.08$"$ pixel size. Vertical velocities were computed at three atmospheric levels (80, 130 and 180 km) using the bisector technique allowing the determination of energy flux in the range 3-10 mHz using two complementary methods (Hilbert transform and Fourier power spectra). Horizontal velocities were computed using local correlation tracking (LCT) of continuum intensities providing divergences. The net energy flux is upward. In the range 3-10 mHz, a full FOV space and time averaged flux of 2700 W m$^{-2}$ (lower layer 80-130 km) and 2000 W m$^{-2}$ (upper layer 130-180 km) is concentrated in less than 1% of the solar surface in the form of narrow (0.3$"$) AE. Their total duration (including rise and decay) is of the order of $10^{3}$ s. Inside each AE, the mean flux is $1.6 10^{5}$ W m$^{-2}$ (lower layer) and $1.2 10^{5}$ W m$^{-2}$ (upper). Each event carries an average energy (flux integrated over space and time) of $2.5 10^{19}$ J (lower layer) to $1.9 10^{19}$ J (upper). More than $10^{6}$ events could exist permanently on the Sun, with a birth and decay rate of 3500 s$^{-1}$. Most events occur in intergranular lanes, downward velocity regions, and areas of converging motions.Comment: 18 pages, 10 figure

Development and Performance Evaluation of a Rubber and Canvas Strip Fingers Defeathering Machine

Human labour requirement in poultry products processing has continued to increase and more demanding, especially defeathering which is faced with faced challenges such as lacerations and hygiene in handling. To solve these challenges, mechanical defeathering proffered a solution, which further posed a problem of equipment cost and efficiency of operation. This paper investigated a developed a low-cost axial-loading (horizontal) defeathering with dual fingers for small and medium-scale poultry processors. This study reported the development of a defeathering machine which comprises of an axial defeathering drum with strip fingers, which flaps on the carcass to pluck off feathers in motion. The machine is electrically powered with a defeathering power requirement of 0.304 kW and at a power rating of 0.269 kW. The performance evaluation carried out with a broiler, cockerel and layer birds at a soaking temperature of 80 degree Celsius for an average time of 1 minutes showed that the efficiency and the effectiveness of the machine varies with respect to the quality of cleaned carcass produced. It was also observed that it takes the machine about 60 seconds to completely defeather a broiler of 2.4 kg weight, 70 seconds to defeather an old layer breed of bird of about 1.2 kg weight and 105 seconds to defeather a 1.3 kg weight of local chicken. However, test carried out on local birds showed that the machine was less effective defeathering local chicken at low temperature, because of the toughness of the skin. Comparatively, canvass (leather) fingers have the highest defeathering efficiency while rubber strip fingers produced the least defeathering efficiency. Therefore, canvas (leather) strip finger performed better than rubber strip fingers

Adsorption of Congo Red Dye from Aqueous Solution using ZnO and Al2O3/ZnO Composite: Isotherm, Kinetic and Thermodynamic Data

Herein, an adsorption study of congo red (CR) dye onto ZnO and Al2O3/ZnO  is reported. ZnO was prepared using conventional chemicals by co-precipitation method and Al2O3 used in the composite was prepared through recycling of aluminium waste. Information about the materials was obtained through spectroscopic techniques. A batch adsorption method was used to obtain the adsorption data from which isotherm, kinetic and thermodynamic parameters were obtained. The result of the adsorbents characterisation revealed the expected properties of the prepared materials. The adsorption capacities at 250 mg/L of CR dye were 24.33 mg/g and 24.57 mg/g for ZnO and Al2O3/ZnO respectively. The isotherm study of the adsorption process revealed that Langmuir model fitted best the adsorption data with monolayer adsorption capacities (qm) of 27.67 mg/g and 33.39 mg/g for ZnO and Al2O3/ZnO respectively. The adsorption was rapid within the first 15 min and the equilibrium was reached at 45 min. The kinetic study followed a pseudo-second-order model with the rate constant of 0.049 and 0.093 g.mg-1.min-1 for ZnO and Al2O3/ZnO  respectively. Experimentally, the process was endothermic and was supported by the positive values of enthalpy (ΔH) with positive values of entropy (ΔS). The change in free energy (ΔG) is negative at all temperatures studied, indicating spontaneity but more spontaneous for Al2O3/ZnO than ZnO. The adsorption of CR dye from an aqueous solution onto ZnO as an adsorbent can be slightly improved upon by the introduction of Al2O3 to form Al2O3/ZnO composite
