ABSTRACT

This research work investigated the geotechnical properties of lateritic soil stabilized with cassava peel ash. The natural soil sample was gotten from Landmark University, Omu-Aran, Nigeria, and were subjected to preliminary soil tests such as natural moisture content, specific gravity and atterberg limit at its natural state. Engineering tests such a direct shear test, permeability and unconfined  compressive strength tests were also carried out on the lateristic soil at their natural states  and at when the cassava peel ash were added to the soil at varying proportions of 0,2,4,6,8 and 10% by weight of soil. The result of the strength tests showed that cassava peel ash enhanced the strength of the interitic soil. The unconfined compressive strength improved from 16.7kN/m2 at natural state to 298.7 kN/m2 at 10% cassava peel ash. The cohesion values also increased from 63 kN/m2  at natural state to 115 kN/m2  at 8% cassava peel ash. The coefficient of permeability values of the modified soil indicates its potential as an embankment fill material with good drainage capacity. The microstructural images of the natural soil and stabilized soil also gave an indication to the effect of cassava peel ash on the soil fabric. Cassava peel ash has a promising potential for stabilizing and improving the properties of lateritic soil.

ABSTRACT

Amblyopia causes impairment of visual acuity, depth perception, and contrast sensitivity and this leads to loss of binocular single vision. This study was conducted to determine the prevalence of amblyopia among primary school pupils in Enugu East Local Government Area of Enugu State, Nigeria. This was a cross-sectional study. A simple random sampling technique was used to select 500 primary school pupils who were examined. Data was obtained using ocular examinations which included visual acuity and pin hole visual acuity testing, cover test. Subjective refraction and fundoscopy were also performed. Amblyopia was defined as best corrected visual acuity<6/9 in one eye or both eyes without ocular pathology in either eye. Data obtained was analysed using the Statistical Package for Social Sciences version 25 and was tested using the Chi-square test with p-value set at 0.05 (p<0.05). A total of 500 pupils participated in the study, out of which 248 (49.6%) were males and 252 (50.4%) females. The mean age of the participants was 8.95 +2.16 years and the age range was from 5-15 years with 307 (61.4%) pupils within the ages of 5 to 9 years and 193 (38.6%) pupils within the ages of 10 to 15 years. Amblyopia was detected in 21 (4.2%) of the screened pupils. Amblyopic subjects were significantly older than non-amblyopic children (P=0.002). The female pupils were more amblyopic than their male counterparts, although the gender variation was not statistically significant. Isometropic amblyopia (n=8, 38.1%) was the most common type of amblyopia (p=0.001). Bilateral amblyopia was observed in 61.9% of the amblyopic pupils. The prevalence of amblyopia in this study was high and therefore adequate public enlightenment about the causes, consequences and prevention of amblyopia should be advocated by eye care service providers and the government.

ABSTRACT

Instructional materials promote efficiency of education by improving the quality of teaching and learning, yet one of the major problems teachers and students encounter in our educational system in Nigeria includes inadequate teaching and learning materials. Hence, this study explores the availability and utilization of instructional materials. The study adopts a descriptive survey design. Instrument for data collection was a check-list and two set of questionnaires for the students and tutors. The sample for the study was arrived at using Yamane’s formula where a total of thirty-one (31) tutors and one hundred and nineteen (119) students responded to the questionnaires. Data collected was analyzed using SPSS version 24.0 where a four scale Likert chat was interpreted using a mean standard of three (3) as reference point for accepting or rejecting each average mean. Findings among others show that apart from white boards for makers and anatomical models of various human organs that are adequately available, only few (35.5%) instructional materials are available and majority (67.2%) of the tutors do not utilize instructional materials in the course of teaching. The study concluded that tutors should be encouraged and monitored on the utilization of instructional materials and It was recommended that adequate instructional materials should be provided by the management of the institution in the course of teaching-learning Nursing.

ABSTRACT: This study examines the empirical analysis of board structure and composition as well as firm performance. Using a sample of 30 UK listed companies, the results confirms that there is no positive relationship between board structure, composition and firm performance in these 30 UK listed firms. It is worth noting that, the major characteristics of corporate governance identified in this research paper are board structure, board composition and firm performance. These results neither did support agency theory, resource dependence and stewardship theory. The empirical evidence of outside board directors and firm performance is mixed. However, some studies such as daily and Dalto(1992), Tian and Lau (2001) and Luan and Tang (2007) concluded in their findings that having more outside independent directors on their boards improves firm performance hence supporting agency theory.  It is not surprising to expect such negative relationship between board structure and composition and firm performance considering the limited sample size of 30 UK listed companies used in the research. The findings of this research shows  that board composition is inversely related to the corporate value because the advantages of monitoring larger boards are outweighed by problems associated with the growing asymmetric information, and additionally larger board sizes are likely to have raised coordination costs, which lessens effective monitoring.  Secondly there are other variables other than the ones the researcher   used to measure firm performance for example corporate social responsibility.

ABSTRACT: Time series plot of a realization of daily exchange rates of South African Rand and Nigerian Naira from April 2017 to December, 2017shows the occurrence of an intervention on 4th August, 2017. This research work has an aim of proposing an intervention model to explain the impact of this intervention believed to be due to the economic recession in Nigeria. Pre-intervention series is observed to be stationary by the Augmented Dickey Fuller Test. Following the shown autocorrelation structure of the series, an adequate subset ARMA (12, 2) model is fitted to it. On the basis of this model forecasts are made for the post-intervention period. Difference between these forecasts and their corresponding actual observations are modeled to obtain the intervention transfer function and the desired overall intervention model. Management of these exchange rates may be made on the basis of this model.

ABSTRACT:

Aggregates and Cement, which are the most important constituents used in concrete production, are the most essential materials needed for the construction industry. This certainly led to a continuous and increasing demand of natural materials used for their production. A large quantity waste is produced annually in the world especially in the construction industry. Because, construction and demolition waste contribute the highest percentage of construction waste. Furthermore, ceramic materials contributes the highest percentage of waste within the construction industry and demolition waste of about 54%. In order to be environmentally friendly post-use, it was considered desirable to use this large amount of waste enumerating from construction industry as a useful raw material to replace coarse aggregate, while mixing the concrete, we used a m ix ratio of 1:2:4, and a water-cement ratio of 0.55 due to the compressive strength of the concrete. We replaced the coarse aggregate with ceramic tiles in three batches plus one batch of the concrete while served as control mix, so as to compare their properties with the aid of some tests. The replacement was in 10%, 15% and 25%. The concrete molds were cast and tested for compressive strength and split tensile strength after a curing period of 7, 14, 28 days. The result shows that increasing maximum compressive and split tensile strength are achieved as replacement percentage increased at 5% interval, the 25% replacement was the maximum in the study.

ABSTRACT:

This study examined the effects of compensation plan on employee performance in the telecommunication industry of MTN and Glo Nigerian, Umuahia. The research adopted the survey research design, using simple random sampling techniques, descriptive statistics and inferential statistics. A total number of eighty-eight (88) questionnaires were issued out by the researcher to the staff of MTN and GLO network providers. 17 respondents representing 21.3% strongly agreed that Prompt payment of salaries has influenced employee performance in the telecommunication industrys, 42 respondents representing 52.5% agreed the same, 7 respondents were undecided, 10 respondents disagreed, while 6 respondents strongly disagreed that the development of the enterprises has increased their access to credit from financial institutions. Also 18 respondents representing 22.5% strongly agreed that Commission has impacted employee productivity in the telecommunication industry, 35 respondents representing 43.8% agreed the same, 9 respondents were undecided, 3 respondents disagreed, while 15 respondents strongly disagreed that Commission has impacted employee productivity in the telecommunication industry. From the regression analysis, the coefficient of bonus and salary are positive and significant at 1%. The p-values of bonus and salary is 0.0064 and 0.0000 is less than the t-statistic value of 2.799 and 9.084 and  the standard error value of 0.0785 and 0.0782 is less than the t-statistic value respectively. The adjusted R2 0.67 or 67% which revealed that the variables in the equation jointly explained 67% of the variations in the equation while the remaining 33% is explained by other variables not included in the equation.  In other words, the R-square value of 67%  expresses the percentage effect of remuneration dimension on employees’ performance jointly explained by salaries/wages and bonus/incentives on employees performance. Therefore, the findings indicates that, (i) Prompt payment of salaries has no significant effect on employee performance in the telecommunication industry. (ii) Commission has no significant effect on employee’s level of satisfaction in the telecommunication industry.
