Toyin Gideon Okedayo, Ayodele Olakiitan Owolanke, Olaseni Taiwo Amumeji, Muyiwa Philip Adesuyi
Open Access Library Journal (OALib Journal) , 2018, DOI: 10.4236/oalib.1104565
Abstract:
In this paper, block procedure for some k-step linear multi-step methods, using the Legendre polynomials as the basis functions, is proposed. Discrete methods were given which were used in block and implemented for solving the initial value problems, being continuous interpolant derived and collocated at grid points. Some numerical examples of ordinary differential equations were solved using the derived methods to show their validity and the accuracy. The numerical results obtained show that the proposed method can also be efficient in solving such problems.
Vision 20:2020 and the Challenges of Infrastructural Development in Nigeria
Mobolaji Olaseni,Wale Alade
Journal of Sustainable Development , 2012, DOI: 10.5539/jsd.v5n2p63
Abstract: Nigeria is the most populous black nation on planet earth and sets a great vision to be among the top 20 economies in the world by 2020 with a minimum GDP of $900 billion and a per capita income of no less than $4000 per annum. This paper argues that infrastructural development is critical to achievement of the vision. Consequently, a discourse on theoretical framework and review of literature on the role of infrastructure in economic development was undertaken. The paper also places the country’s economy in a global context and assessed the state of infrastructural development in the country. Also, factors responsible for the current state of infrastructural development in the country were examined. The paper reveals that two years into the vision, the country’s economy is growing at a very low pace than envisaged. It also reveals that the quantity and quality of infrastructure needed to propel a rapid economic development are absent. The paper recommended adequate funding of infrastructure in critical sector, transparency and good governance, population control and physical planning of settlements among others for the realization of the vision. The paper concluded that the war of economic transformation through infrastructural development in the country would be lost or won in our settlements where productive economic activities are located; hence physical planning that will propel infrastructure development in major settlements and across the regions of the country is germane to the realization of the 2020 vision.
An Appraisal of Road Condition Effect on Rural Transportation in Sekyere Central District of the Ashanti Region of Ghana  [PDF]
Adewunmi Taiwo, Francis Kumi
Journal of Transportation Technologies (JTTs) , 2013, DOI: 10.4236/jtts.2013.34028
Abstract:

The objective of this study was to assess the condition of the road network within the district with a view to find out if and how they affect the transportation costs. Four sets of primary and secondary data on the district’s road surface types, road condition mix, cost of transportation of farm produce and humans on the road network were collected, collated and subjected to statistical analysis using a Completely Randomized Design. The results indicated that the road conditions had high significant effects on the transportation costs of both human and agricultural produce. The road network of the district consists of 21 roads with a total length of 176.6 kilometers out of which 8 were classified as poor, 7 as fair and only 6 as good. The highest agricultural produce transportation cost of \"\" 1.46 per tonne-kilometer was obtained from 3 of the poor roads while the lowest cost of \"\" 0.86 per tonne-kilometer was obtained from only 1 of the 6 good roads. The highest passenger transportation cost of \"\" 0.3 per passenger kilometer was obtained for 1 of the 8 poor roads while the lowest cost of \"\" 0.1 per passenger kilometer was obtained for all the 6 good roads and 4 of the fair roads. In conclusion, transportation cost of passengers on the poor and fair roads was 2 - 3 times as high as the cost of transportation on the good roads. Transportation cost of agricultural produce on the poor roads was 70% higher than it was on the good roads.

Modern Economy (ME) , 2014, DOI: 10.4236/me.2014.52014
Abstract:

This study examined the relationship between insurance and economic growth in sub-Saharan Africa over the period 1986-2011. Pooled OLS, Fixed Effect Model and Generalized Method of Moment Panel Model were employed in the estimation. The estimations of the dynamic panel-data results show that insurance has positive and significance impact on economic growth in sub-Saharan Africa. This shows that premium contributes to economic growth in sub-Saharan Africa which means that a well-developed insurance sector is necessary for the economic development, as it provides long-term investments for economic growth and simultaneously strengthening risk-taking abilities. The results also show that human capita has positive significant impact on economic growth. Openness and interest rate have negative and statistical significant on economic growth.

Predictors of psychopathology among Nigerian adolescents: the role of psychosocial, demographics, personality and medical condition reports domains

African Health Sciences , 2011,
Abstract: Background: Psychopathology among adolescents has become a global concern in the last decade. Objective: The aim of this study was to identify the predictors of psychopathology among adolescents in Ibadan region using a multi-theoretical approach. Methods: Eight hundred and eighty-nine (889) male and female adolescents drawn from different parts of Ibadan region of the South-West Nigeria, participated in the study. The study is a cross-sectional survey and adopted an ex-post facto design. A questionnaire divided into six sections, with two versions was used for data collection. Analysis of data involved multiple/stepwise regressions, F-test & T-test. SPSS 10.0 computer programme was utilized for all analyses. Results: Data showed that all the predictors jointly contributed 37% (P<0.0001) to the prediction of reported psychopathology. The domains of psychosocial, personality, demographic and medical condition reports all independently and significantly predicted psychopathology among the adolescents but psychosocial domain had the highest contribution of 16% (P<0.0001). Prevalence rate for psychopathology among the sampled adolescents was 0.152 (15.2%) at the criteria of one standard deviation above the mean. Conclusion: It is concluded that a multi-theoretical approach to the understanding of psychopathology among adolescents will be more appropriate in the Nigerian community. Results have implication for further assessment and treatments. Parents are advised to report any behavioural dysfunction observed in their wards to experts early enough to avoid degeneration to greater psychopathology in the later years.
A Socio-cultural Analysis of Yoruba Discourse Patterns in selected Child Welfare Clinics in Southwestern Nigeria

Abstract: This paper is the report of a study that examined discourse patterns in the discourse of nurses and mothers at some Child Welfare Clinics (CWCs) in Southwestern Nigeria. It describes and analyzes significant elements of recorded discourse chunks in breastfeeding, ORS/ORT and General cleanliness; as well as discourse strategies employed by interactants of both classifications (nurses and mothers) involved in the socio-linguistic activity, exemplifying how language is used to exercise and buttress relationships in the clinics. The study reveals that communication is primary to effective health care; while both parties were willing to cooperate in order to achieve their main goal. The implication of all these is pointed out while it notes that communication whether in English, the mother tongue or the “father tongue”, is crucial and in this case, effective, educative and entertaining. The study concludes that in order to cope with short-staffing, literacy and education constraints, resorting to indigenous Yoruba discourse patterns and discourse modalities is a viable option in the pursuit of the goals of the PHC. Key words: Discourse patterns; Primary Health Care; Poverty-related challenges
Response Elicitation in English-medium Christian Pulpit Discourse (ECPD)
Taiwo, Rotimi
Linguistik Online , 2006,
Abstract: The study is an investigation into the various ways pulpit preachers in Christian religion elicit responses from their congregation. The data for the study consists of messages delivered from the pulpit at denominational, non-denominational and interdenominational Christian services in South-Western Nigeria. Working within the framework of Sociolinguistics and Discourse Analysis, the analyses reveal that preachers control the discourse, while the worshippers share in the process of creation of the text as it unfolds. For instance, they determine what responses are given, how they should be given and when to give them. It was also observed that response elicitation is done through the use of interrogatives, declaratives and imperatives, and such responses may come in forms of speech, physical action, and mental behaviour. Our analyses reveal a preponderance of spoken responses in the data. Five kinds of spoken responses are identified in the data, namely: Conventional Answer (CA), Response to Prayers (RP), Repeated Statements (RS), Gap Filling (GF), and Corrected Statement (CS). The study concludes that despite that the way responses are elicited depends largely on the practices of any religious community, certain patterns of elicitation are common in ECPD. The degree of control and the kind of response elicited by a preacher are determined by the language expectations of the community. Such expectations include knowledge of the language code, principles, norms, use, situation and the world of such religious communities.

Managing Language Testing in Nigerian Large Classes: Processes and Prospects
Taiwo Abioye
English Language Teaching , 2010, DOI: 10.5539/elt.v3n2p82
Abstract: The demand for literacy in a developing country like Nigeria has multiple results such as the expansion, by leaps and bounds, of the average Nigerian classroom. This paper highlights the reasons for large classes in Nigerian secondary schools, the educational and psychological dimensions of language testing in large classes, the challenges of such classes and how they affect achievement and in the long run, the standard of education. It also tasks the proficiency levels of English Language teachers especially in the area of testing and points out new paradigms in language testing, particularly in large classes from the two perspectives of human and infrastructural development, and teacher empowerment and initiatives. The study suggests methods of improving language testing in large classes through pragmatic techniques.
