Y. Skwame, I. J. Bulus, J. Sabo. Department of Mathematics, Adamawa State University, Mubi
The application of multiple off mesh implicit first and second order backward differentiation formula for the solution of stiff ordinary differential equations was developed via interpolation and collocation methods in this paper. In deriving the methods, we use the power series as a basis function to obtain the main continuous schemes.The analysis of the method was study and it was found to be consistent, convergent and zero?stabile with stability regions. The newly constructed methods was applied to on four systems of ordinary differential equations. We further compare first derivative with second derivative on each problems. It is obvious that, the second derivative performs better than the first derivative on all the problems.

IMPACT OF CONVEXITY IN NON-LINEAR CONSTRAINED, * OPTIMIZATION PROBLEMS IN R . A CASE STUDY OF OVASON MOLDING COMPANY.
Mark Ugo Department of Statistics, School of ICT. Federal Polytechnic Auchi, Edo State
In our production sectors, the knowledge of optimization problems is paramount and cannot be over emphasized. It is one of the bed rocks for manufacturers and decision makers in various fields of discipline to make accurate and precise judgment on real world problems that can be recast as optimization problem. To achieve such laudable objectives, various methodologies have been adopted and applied, hence this research work. In this research work, one of the methods adopted is the application of the Lagrangean function that satisfied Kuhn and Tucker conditions on the real world problems extracted from Ovason Molding Company. The problem as extracted from the company is a Non-Linear Constrained Optimization Problems that is based on finite 4 dimensional space in . In this problem, we specifically examined ?Impact of R Convexity? on the cost minimization problem of the company in producing at least one low tension (LT) of concrete electric pole and hence applied the Lagrangean function that satisfied Kuhn and Tucker conditions for optimal solution. The solution obtained is based on characterization (continuity and differentiability) of convex and concave functions. From our findings it is discovered that the result of the problem actually depicts reduction in price for producing one low tension (LT) of concrete electric pole, as against the market price of the company. The result of the problem indeed stands to correct among other things wrong impressions created by the manager of the company about prices of such commodity.

1 Kigira, Yakubu Sa’adu Department of Educational Foundations, Nasarawa State University, Keffi Nasarawa State 2 Bode-Oke Olusala National Commission for Colleges of Education (NCCE) Abuja 3 Innocent Ikpa PhD Nigeria Security and Civil Defense Academy Katsina, Katsina State, Nigeria Abstract
This paper examines social networking sites use among fresh undergraduate students of Nasarawa State University Keffi as predictors of social adjustment to University environment. Arandomly selected 346 (male=173 and female=173) students participated in the study. Quantitative research design was employed to analyze the data. An adopted version student adaptation to college questionnaire (SACQ) developed by Baker and Sirkyk (1989) and a scale to measure the propensity for students to use social networking sites (SNS ) S for positive collaboration (Lampe, Wohn, Vitack, Ellison & Wash, 2011) were used for data collection. Each of them had five points Likert typed response. The instrument was validated by three experts in the Department of Educational Foundations, Nasarawa State University Keffi. Reliability of the instrument was determined by pilot study which yielded the Cronbbach’s alpha reliability of .84 and .87 respectively. Data collected were analysed using descriptive statistics( frequencies, percentages, means and standard deviation), Pearson product moment correlation, standard multiple regression and t- test via Statistical Package for the Social Sciences (SPSS) version 21. The findingsrevealed thatstudents were more familiar with face book and least with instagram. There was a significant negative relationship between SNSs and student social adjustment to university environment. SNSs use did not significantly predict fresh undergraduate students to university environment. There was statistically significant sex difference in SNSs and social adjustment in favour of girls. Based on the findings, the study concluded that other variables not considered in the study played significant roles in contributing to fresh undergraduate students of Nasarawa State University Keffi. It was recommended among others that Universities should take some responsibilities for encouraging students to utilize the SNSs use to foster their social adjustment to university environment.

Samuel Nariochukwu Owhondah, Ph.D Department Of Educational Management, Faculty Of Education, Ignatius Ajuru University Of Education, Rumuolumeni, Port Harcourt, Rivers State
The study determined the demand and supply of education and price discrimination in private secondary schools in Rivers State.Three research questions guided the study. The descriptive survey design was adopted for the study. The population constituted ninety-nine private secondary schools in the area while the sample was ten schools which represented 10% of the target population. The Demand, Supply of Education and Price Discrimination Inventory (DS PDI) of Private Secondary Schools and the a document analysis were used for data collection. Using the Cronbach alpha, reliability index of 0.77 was obtained. The averages of the data generated were computed. The results revealed that the demand for education was low and supply was high due to discriminatory prices (fees), and with a low student-teacher ratio. It was therefore concluded that private schools that charged high fees also had high teacher supply and that culminated in low student-teacher ratio and impacted quality education in those schools. It is recommended that private schools should be made affordable for students to attract high demand, and supply should be regularly checked with demand to maintain the approved student-teacher ratio for the attainment quality education. Besides, more private individuals should be encouraged to invest in private secondary schools at reduced fees to avert imbalance and augment public secondary education.
