Effects of crude oil contaminated-soil on the germination and growth of cowpea Vigna unguiculata (L.) Walp
Get PDFA greenhouse experiment was conducted to investigate the germination and growth response of cowpea (Vigna unguiculata(L.) Walp) to soils contaminated at different concentrations of crude oil. This was done with a view to access the impactof crude oil pollution on growth and nutrient content after harvest. The contaminated crude oil polluted soils wereprepared at different concentrations of 0.0, 10.0, 20.0, 30.0, 40.0 and 50.0 (w/v) on 5 kg each of air-dried soil collected fromthe Obafemi Awolowo University Biological Garden rich in organic matter. Each treatment was replicated three times andarranged in complete randomized design. The following parameters, leaf length, breadth and leaf number, N and proteinwere determined. Results showed that leaf length, breadth and leaf number were significantly higher (p<0.05) recorded inthe control pots. The least % N and protein were recorded in the pots with highest crude oil concentration (50.0 ml). Theresults also showed that increasing crude oil concentration, posed higher risk of edibility of the test-plant and nodetectable amount of petroleum hydrocarbon was found in the soils at the end of the experiment. The study concludedthat although cowpea germinated and grew well in crude oil-contaminated soils, its nutrient content was impaired andedibility not guaranteed
DEVELOPING THE POTENTIALS OF AFRICA THROUGH GIRL- CHILD EDUCATION: A CASE STUDY OF NIGERIA AND CAMEROON
Get PDFEducation is fundamental to poverty reduction and it equips individuals to contribute immensely to the socio-economic development of society. However, studies have revealed a wide gap in gender enrolment in primary education in Sub-Saharan Africa, Nigeria and Cameroon inclusive caused by gender issues and socio-cultural beliefs among other practices, as well as deeper forces that extend beyond the boundaries of educational systems. This study therefore investigated the trends in girl-child participation in primary education in Nigeria and Cameroon and the causes of disparity. The study adopted descriptive survey design using the ex-post facto method. Two research questions and two hypotheses were raised in the study. The instruments used for this study were the Parent’s Questionnaire on Girl-Child Participation in Primary Education (PQGPPE) and Questionnaire for Street Girls of Primary School Age (QSGPSA). Data collected were analysed using chi-square, T-test and descriptive statistics. There is high perception of parents in Nigeria and Cameroon (Nigeria; Weighted Average = 2.79, Cameroon; weighted Average= 2.94). There is no significant difference in the responses of street girls and parents on factors militating against girl-child education. Hence, hypotheses 2a and 2b are accepted. T-test comparison of Girl-Child Enrolment shows that the girls’ enrolment in Cameroon is higher ( = 45.6) than that of Nigeria ( = 40.7) at (t = 12.33; df =30; p <.05). Girl-child participation in primary education in both countries is not encouraging and socio-cultural and economic factors are predominant causes hindering their accessibility. Therefore, cultural practices like early marriage, preference for boy-child education, among others should be discouraged by governments of both countries.  
TIME MANAGEMENT AMONG MANAGERS IN ORGANISATIONS IN LAGOS STATE, NIGERIA
No full textGlobalisation and the increased competition both in product and in service organisations today have posed challenges for managers and as such increased efficiency, effectiveness and productivity is demanded. More attention needs to be given to time management in Nigerian organisations in order to improve productivity both in public and in private sectors. This study investigated through empirical methods the extent to which managers in Nigeria plan their activities, delegate duties and authority to subordinates.
Out of 200 managers and top level supervisors/officers sampled in four organizations in Lagos State, 185 respondents responded. A Likert-Type of questionnaire was used to gather data which was analysed using frequency counts and percentages. The findings reveal that managers in Nigeria generally make short- and long-term plans but very few plan their daily activities. Those who make “to-do-list” cannot “work-their-plans” due to the schedules of their immediate superiors or even distractions in the workplace and environmental factors. The extent to which managers in Nigeria do delegation is low. Most of them prefer to complete their assignments themselves, and this causes pressure and stress.
The study concluded that managers in Nigeria need to adopt various time management techniques including more delegation in order to accomplish goals and objectives. Recommendations were made for management to organise seminars for their management staff on how to improve time management and productivity
CONFLICT IN SCHOOL CLIMATE: A SYNOPSIS OF ITS NATURE, CAUSES, EFFECTS AND MANAGEMENT APPROACHES
Get PDFSchool climate is a functional variable that determines the nature of social activities that will take place in a school. Its functionality is based on how emerging conflicts are constructively managed to make positive impacts on people and the system. Based on this, the study examined the nature, causes, effects and management approaches of conflict in the secondary school climate in Adamawa State. The study adopted a descriptive research design, using a questionnaire entitled “Conflict and School Climate Questionnaire (CSCQ)” to gather the required data. Seven hundred and sixty teachers (760) were selected through a random sampling technique from Yola and Numan educational zones in the state. Percentage, chart and graph were used to analyse the data collected. The result shows that teacher-student conflict (TSC) was the main form of conflict confronting teachers in secondary school climates. The study also discovered that collaborating conflict handling style was the major approach that teachers employ to resolve conflict, followed by accommodation approach. The causes and effects of conflict in secondary school climate were discovered. Implications for peaceable classroom and policy options were highlighted
DETERMINANTS OF EMPLOYABILITY OF PERSONS WITH HEARING IMPAIRMENT IN SELECTED ORGANSITIONS IN OYO STATE, NIGERIA
Get PDFThis study investigated the determinants of employability of persons with hearing impairment, in some selected organizations in Oyo State. Questionnaires were administered to 100 employers of labour in order to determine the employability of person with hearing impairment. The study used a descriptive survey research design. Multiple regressions was used to analyse the research questions and t-test statistics was used for the hypothesis at 0.05 level of significant. The findings revealed that age, severity of hearing impairment, sex and psychological adjustment were the major determinants of employability of person with hearing impairment. It was also discovered that there was no significance difference in the attitude of public and private organization to employability of persons with hearing impairment. Based on these findings, it was recommended that the curriculum for students with hearing impairment should included career awareness training and social interpersonal communication activities
QUALITY OF WORK LIFE AS PREDICTOR OF PERCEIVED EMPLOYEE'S JOB COMMITMENT IN THE FOOD AND BEVERAGE INDUSTRY IN LAGOS STATE, NIGERIA.
Get PDFThe study examined the joint and relative effects of elements of Quality of Work Life on Employee Job Commitment in Food and Beverage Industry, Lagos State, Nigeria. A correlational research design was adopted and a sample of 610 respondents was selected through multi-stage sampling techniques. Data were collected through Quality of Work Life Scale(r=0.85) and Perceived Employee Job Commitment Questionnaire (r=0.75). Two hypotheses were tested and data analysed through multiple regression. The four elements of Quality of Work which constitute the independent variables jointly predicted employee’s job commitment of the respondents(R=0.467). Precisely, the predictors contributed 21.3% (adjusted R2 =0.213) to the variance of the criterion variable. Also, each of the independent variables with the exception of career development significantly (p<0.05) predicted the dependent variable. Based on the findings, it was suggested that employers of labour especially in the organized private sector should endeavour to offer competitive compensation to their workers, maintain good occupational health and safety and make job relatively stabled. 
FUND UTILISATION AS DETERMINANTS OF STUDENTS’ ACADEMIC PERFORMANCE AMONG PUBLIC UNIVERSITIES IN NIGERIA
Get PDFInadequate funding of the Nigeria’s public universities had become an unresolved problem in the educational body polity. When the students’ enrolment trend is on the increase without a commensurate funding inflow, it portends great dangers particularly for academic performance. The thrust of this paper was to propose effective fund utilisation and enrolment control as determinants of good academic performance among the public universities in Nigeria. The study adopted a descriptive survey design. Twenty-one public universities in Nigeria was selected through stratified random sampling technique from three out of six geo-political zones viz south west, north central and north west. The study participants comprised key university administrator including Bursary, Directors of Academic Planning and Directors of Students Affairs of selected universities. Three instruments: University Funding and Fund Utilisation Inventory, University Enrolment Inventory and University Students Academic Performance Inventory were used for quantitative data collection. Research hypotheses were tested at 0.05 level of significance. Data were analysed using descriptive statistics and Multiple Regression Analysis. Fund utilisation of public universities on academic related matters had a positive but not significant correlation with students academic performance. Direct and indirect academic (b=0.42; t=165; p>0.05) and library and ICT development expenses (b=0.41; t=0.61; p>0.05). The combination of the predictors however, explain 17.6% of the total variance observed in the students academic performance. The linear combination of fund generation, fund utilisation (academic and non-academic matters) and students’ enrolment had significant influence on students’ academic performance in public universities in Nigeria (F(3,10)=15.16, p<0.05). The higher enrolment was noticed among the older Federal Universities when compared with their state-owned counterparts during the period of study. The students’ enrolment in the public universities had significant negative correlation with their students’ academic performance (r=0.89, p<0.05). Funding and fund utilisation in isolation do not have significant influence in improving students’ academic performance. Students’ enrolment is a significant determinant of academic performance, while the linear combination of funding, fund utilisation and enrolment had significant influence on students’ academic performance in Nigeria’s public universities. Hence, both the Federal and State Governments should always endeavour to put in place regulatory mechanism for optimum students enrolments and effective fund utilisation for academic programmes by educational manager
ISSUES AND CHALLENGES OF QUALITY ASSURANCE IN OPEN AND DISTANCE LEARNING INSTITUTIONS IN NIGERIA
Get PDFThis paper gives an insight into the meaning of quality, assurance, quality assurance and quality assurance in ODL. To the relativists, quality is like beauty that lies in the eyes of the beholder while the objectivists believed that quality can be specific attributes that can be identified. Quality is the responsibility of everyone in an educational institution and it should be a continuous process and not considered as one-time activity. However, assurance is primarily about ensuring accountability to stakeholders. It is a confidence that one has about a thing after all possible doubt has been eliminated. Quality assurance is a process through which a higher education institution guarantees to itself and its stakeholders that its teaching, learning and other services consistently reach a standard of excellence. Quality assurance could be internal or external. Quality assurance in ODL includes developing and producing learning materials, academic programmes, service and support, as well as standards of students learning. The paper also identified competition, customers’ satisfaction, maintaining standards, accountability, improving employee’s morale, motivation, credibility, prestige and status and image and visibility as some of the issues in ODL. While contribution to national development, devising a credible and universally set of quality assurance, fostering global competencies among students, inculcating a value system in students, promoting the use of technology, quest for excellence and availability of practitioners are some of the challenges of quality assurance in ODL institutions in Nigeria
THE INFLUENCE OF SOME DEMOGRAPHIC VARIABLES, PARENTAL AND PEER FACTORS ON BULLYING BEHAVIOUR AMONG SENIOR SECONDARY SCHOOL STUDENTS IN IBADAN, OYO STATE
Get PDFThis study investigated the influence of gender, age, religion, family size, family income, parental and peer influence on bullying behaviour among senior secondary school students in Ibadan, Oyo state. A sample of two hundred and fifty adolescent students was selected using stratified random sampling from five senior secondary schools in Ibadan city. Fifty respondents were selected from each school. Bullying Rating Scale, Parental and Peer Influence Rating Scales were used in eliciting information. Three research hypotheses were tested. The data were analysed using multiple regression analysis and Pearson product moment correlation analysis. Result showed that bullying is positively correlated with gender, family type, religion, family size, parental influence, peer influence, age. Parental influence made the most significant contribution to the prediction of bullying behaviour. Based on the findings of this study, helping students learn how to understand and manage their feelings may provide them with tools to avoid escalating negative feelings so as to avoid serious confrontations with other students, teachers, and administrators
SUPERVISORY ROLE OF PRINCIPALS AND QUALITY ASSURANCE IN SECONDARY SCHOOL SCIENCE EDUCATION PROGRAMME
Get PDFIn this study, the author assessed teachers’ perception of principals’ supervisory role in quality assurance in secondary school science education programme. The study was based on the assumption that if school principals properly supervise teaching and learning activities in science classes then teachers will teach very well and students’ learning outcomes will improve. One hundred and seventy-nine science teachers who were randomly selected from 58 secondary schools in Ibadan City, Oyo State, Nigeria participated in the study. One valid and reliable questionnaire titled “Teachers Perception of Principals Supervisory Role (TPoPSR)” was used to gather data. Three research questions were answered. Data were analysed by using mean, standard deviation, frequency counts and percentages. For the interpretation of the results, a bench mark of 2.5 was set for the mean values of the participants’ responses to each of the 19 items contained in Part A and Part B of TPoPSR. On the basis of bench mark set, the teachers were of the opinion that principals were performing their role in the area of classroom inspection. Results also show that the teachers expected their principals to do more in the area of checking teacher’s note of lesson, teacher’s mark book and students’ notebook. More importantly, results show that teachers do not expect their principals to make informal visits to their classroom and evaluate teachers’ content knowledge. The results of the study have brought to focus the level at which secondary school principals perform their supervisory role. The results of this study show that teachers expected their principals to play more supervisory role than they do at present, especially in the area of monitoring teachers’ and students’ written work.
