The Nigeria Start-up Act 2022 as a Catalyst for Technological Development and Economic Growth in Nigeria

This century has heralded technological advancement in human history, particularly in Africa. The influx of technological advancement currently in play all over the world and the economic benefits that come with such advancement has necessitated the need for some regulations. Hence, stakeholders particularly, governments all over the world have made efforts to regulate and support investments in technology. These supports include laws, policies and other incentives that promote technology. Recently, the Nigerian National Assembly passed the Nigeria Start-up Act (NSA), 2022 to provide a regulatory framework for the development of start-ups as well as to provide an enabling environment for the establishment, development, growth and operation of start-ups and technology-related talents in Nigeria. The Act also seeks to position Nigeria’s start-ups ecosystem as a leading digital technology centre in Africa in terms of excellent innovators with exportable skills and capacity. It is projected that the NSA will immensely contribute to technological development for Nigerian start-up companies to compete with their counterparts at the regional and international scene. This article examines the nature of start-ups and the Nigeria Start-up Act, 2022. It further analyses the pre-enactment of the Start-up Act era in Nigeria, the emergence of the Start-up Act, the impacts the Start-up Act might have on technological development, the challenges of the Act as well as the general challenges faced by start-ups in Nigeria. The article argues that the NSA is a welcome and commendable effort for technological development and economic growth in Nigeria

Parental Involvement as a Determinant of Academic Performance of Gifted Underachieving Students in Akinyele Local Government Area of Oyo State

Extensive research has shown that the underachievement of capable children is an area of concern for many parents and educators. This study investigated the role of parents in enhancing academic performance of underachieving students in Akinyele Local Government Area of Oyo State, Nigeria. The study adopted a descriptive survey design. A sample size of one hundred (100) was randomly selected using stratified random sampling technique with forty nine (49) males and fifty one (51) females. Majority of the subjects used fell within the ages of seventeen (17) and nineteen (19). A structured questionnaire and verbal interview method were used to collect data from the selected subjects. Three hypotheses were tested using percentiles and normal distribution as statistical tools for data analysis. The findings showed that there was no significant difference between the academic performance of underachieving students with single parent and those with both parents (Crit – t = 1.96, Cal. t = 0.798, df = 98, P > 0.05 level of significance). The findings also showed that there was no significant difference between the academic performance of underachieving students whose parents live in the urban area and those whose parents live in rural area (Crit – t = 1.96, Cal. t = 0.186, df = 98, P > 0.05 level of significance). Finally, the result also indicated that there was no significant difference between the academic performance of underachieving students whose parents are of low socio-economic status and those whose parents are of high socio-economic status (Crit – t = 1.96, Cal.t = 0.135, df = 98, P > 0.05 level of significance). Keywords: Parental involvement, Academic performance, Gifted Underachieving students

Multivariate Regression of Liver on Intestine of Mice: A Chemotherapeutic Evaluation of Plant Extracts

Mice infected with 50 cercariae of Schistosoma mansoni in unequal group sizes were challenged with some doses of Zingiber officinale extracts, Cremophore and Praziquantel. Data were available for the number of maleand female parasites, weights of liver and intestine, and egg per gramme liver and intestine tissues. Using an analysis of covariance model, the effectsof the extracts and compound on intestine were predicted. The findings revealed, with the aid of likelihood-ratio statistic, a marked improvement inthe precision of the estimates of the effects on intestine when the liver was taken into consideration.Key Words: Shistosomiasis; Multivariate Regression; Likelihood-RatioStatistics

A Simple Proof of the Generalization of the Binomial Theorem Using Differential Calculus

The binomial theorem is a simple and important mathematical result, and it is of substantial interest to statisticalscientists in particular. Its proof and applications appear quite often in textbooks of probability and mathematicalstatistics. In this article, a new and very simple proof of multinomial theorem is presented. The new proof isbased on a direct computation involving partial derivatives.Key Words: Binomial distribution; Combinatorial Analysis; Mathematical Induction; Multinomial theorem;Partial derivatives

Relevance of the Mathematics Education Programmes of the Nigerian Colleges of Education to the Teaching of Junior Secondary Mathematics

The education system in Nigeria is faced with a mirage of defects which hinged on man power used in carrying out the teaching and learning process. This study considers the relevance of the mathematics education programmes of the Nigerian Colleges of Education (NCE) to the teaching of junior secondary mathematics. This was with a view to providing necessary information for later mathematics education curriculum revision in NCE. The subjects of the study included Heads of departments of mathematics in five Colleges of Education in Southwestern Nigeria as well as 179 teachers of 49 secondary schools with the region. The employed a survey design with two instruments namely: Content Analysis Discrepancy Model (CADM) and Mathematics Teachers’ Questionnaire (MTQ) used to obtain the closeness of Colleges of Education mathematics curriculum with that of NCE and used to enquire which of the mathematics contents in JSS the teachers were equipped to teach, respectively. Findings from the descriptive analysis of data revealed that mathematics education programme run by the Colleges of Education was 96.36% relevant to the junior secondary mathematics curriculum. It is also revealed that all the NCE teachers can teach up to 70% of the JSS mathematics topics. The findings bring into focus the need that 82% of the experienced NCE and 18% less experienced NCE teachers wanted a review of the mathematics education programme of the Nigerian Colleges of Education.
