The Phenomenon of Gemination in English and Arabic (Published)

Gemination is a phonetic phenomenon whereby two identical /sounds/ co-occur in one word or at words boundaries. The co-occurrence of two identical sounds doesn’t matter, what matters is their pronunciation. Whether to pronounce them as one sound or two sounds is a matter treated differently across languages that have geminate sounds. As the present paper restricts itself to two languages only, Arabic and English, it investigates how gemination occurs in the two languages and how it can be represented? Is it restricted to consonants only or it can also occur with vowels? What type of gemination each language exhibits? These questions beside some more others are the main concern of the present paper in which the phenomenon of gemination is clarified in general, then a study of gemination is presented in English and Arabic respectively. There is a common view point which holds that English does not have gemination, but in fact it appears that English has gemination at certain conditions. Although it is unlike Arabic in its realization, but it can be said that gemination exists in English.

Minimization Comparison of Surface Roughness Drilling Value of Mild Steel, Stainless Steel and Brass: An Application of One-Way Anova Technique (Published)

The study investigated on minimization comparison of surface roughness drilling value of mild steel, stainless steel and brass using one-way analysis of variance (ANOVA) technique so as to check for significant difference between the workpiece in their value of surface roughness using the same process parameters irrespective of their material properties. The experimental data used in the comparison were conducted nine (9) times for each of the workpiece. The descriptive statistics and the Tukey post hoc test of the ANOVA revealed that there were no statistically significant differences between the minimization surface roughness value of mild steel, stainless steel and brass. The result implies that irrespective of the material properties of the workpiece under the same process parameters condition, there are equal significant variation of surface roughness on mild steel, stainless steel and brass. The study concludes that regardless of the material properties for machining investigation using the same parameters, it is possible to have the same quality effect of surface roughness in terms of it minimization target.

On the Comparison of Statistical Curvature with Gaussian Curvature (Published)

Efron [1] introduced the new statistical curvature to measure the shape of a one-parameter exponential family.  This family, through the sample space of all possible probability distributions, can be considered a “straight line”. In this paper, using the student t-distribution, we compare this new statistical curvature with the classical Gaussian curvature. Efron’s defined curvature has greatly reduced the quantities of curvature. In order to compare Efron’s statistical curvature with the Gaussian curvature this paper will look at the degree of freedom.

COMPARISON OF STANDARD FOUR PUPILS’ ACADEMIC PERFORMANCE IN PUBLIC AND PRIVATE PRIMARY SCHOOLS AFTER THREE YEARS OF FREE PRIMARY EDUCATION (F.P.E.) IMPLEMENTATION (Published)

In Kenya, basic education is provided through public and private institutions. . This paper focused on class 4 pupils admitted in class 1 the year 2003 when Free Primary Education (F.P.E.) programme was implemented. The purpose of this study was to compare the academic performance of these pupils in Private and Public Primary Schools. The research made use of ex post facto research design. Simple random sampling was used to select eight public and eight private primary schools in Kitale Municipality. A test was given to class four pupils of the year 2006 in both private and public primary schools and used to assess academic performance. The study used descriptive statistics to compute data for academic performance. The tests of significance showed disparity in academic performance of both boys and girls in private school from those of the public. There is need for education and policy assurance officers to step up inspection to enhance effectiveness among public primary school teachers.
