Numerical Solution of Systems of Integro Differential Equations Using Polynomial Collocation Method
No full textThis paper deals with the development of a new numerical scheme to solve systems of linear integro differential equation under mixed conditions. The new method adopted the use of standard collocation points to transform the state equations into linear algebraic equations. These equations are then solved using MATLAB programming through the matrix inversion technique to obtain the unknowns. The convergence of the method is established and numerical examples are solved and compared with existing results to confirm the efficiency of the new method
CAPTURING EXCESS ZEROS IN MODELING AUTO-INSURANCE CLAIMS IN AN INDIGENOUS INSURANCE FIRM USING ZERO INFLATED MODELS AND HURDLE MODELS
No full textCount data occur naturally in a number of disciplines ranging from economics and social sciences to finance as well as medical sciences. Most count data are plagued with over-dispersion and excess zeros making it difficult to model them with vanilla linear models. Different models have been proposed to capture this peculiarity in count data viz.: A number of classical regression models such as the generalized Poisson and negative binomial have been used to model dispersed count data. Hurdle and zero-inflated models are also said to be able to capture over-dispersion and excess zeros in count data.
In this paper, we compare the performance of Poisson and Negative Binomial hurdle models, zero-inflated Poisson and Negative Binomial models, classical Poisson and Negative Binomial regression models as well as the zero-inflated compound Poisson generalized linear models to modelling frequency of auto insurance claims in a typical emerging market.
The model parameters are estimated using the method of maximum likelihood. The models performances are compared based based on some model selection criteria, including: Akaike and Bayesian information Criteria (AIC and BIC), and Gini index. The zero-inflated compound Poisson generalized linear models performed better than the other models considered
Coronavirus: One word, Many Pronunciations among Nigerians
No full textCoronavirus (Covid-19) is a disease that affects the respiratory tract. Since the emergence of this disease in Wuhan province of China towards the end of 2019, it has spread to all parts of the world including a multilingual nation, Nigeria with over 500 languages. Articulation of foreign medical terms is not always easy among the basilect English speakers in Nigeria. Consequently, the interactions and discussions of Coronavirus have generated various pronunciations that this study is set to examine. A total of 50 short real-life videos and audio clips made up of 30 adult males, 17 adult females, 2 teenagers (1 male and 1 female) and 1 pupil were gathered online. The data were analyzed using the socio-phonetics method. Results show that the word Coronavirus has eighteen pronunciation types among Nigerians. Strategies employed in trying to adapt to the pronunciation of Coronavirus includes sound substitution, sound deletion, sound insertion, and other forms of neologism. This study has established various phonetic interventions in the COVID-19 discourse in Nigeria. The study concludes by advocating for official adaptation of medical terms such ‘Coronavirus’ and the ‘likes’ into local languages
There’s a TINGLING IN MY THROAT: IS that you CORONA?
No full textIt's the tenth day of the lockdown over the coronavirus pandemic. It‟s been a dreadful ten days, and I‟ve just exhausted my stock of groceries. The government told us to prepare for a fourteen-day lockdown in the first instance. I prepared. I purchased enough food stuff and toiletries to last fourteen days. There are at least four more days to endure the "stay at home‟ order. If we are lucky. The Lagos state government is threatening to extend the lockdown “if Lagosians don‟t behave themselves.” I‟m an obedient Lagosian. I obey the rules. I endure the anxiety and paralysing fear of getting infected. There are rumours that the virus could be airborne. So I shut my windows and cascade in sweat, even when there‟s no electricity to power the fan or air conditioner that have become basic necessities. These measures, as tough as they are fail to take away the fear in me. Each time I feel a tingling in my throat, I ask: Corona, is that you? I jump around panicking, and pace about my room until I collapse into bed in exhaustion. I have been sufficiently educated to know that the virus comes stealthily with tingling. Then, it makes your throat itch, and consolidates its invasion by making you sneeze and cough before it takes total possession of your lungs. I self-regulate, stifling any sneezes and coughs attempt to betray my discipline. Traitors. Although I‟m far away from the instruments for testing, each time I feel a tingling in my throat, I tell myself repeatedly that Corona will not invade my lungs
CONSCIENTIZATION: A CRITICAL ELEMENT FOR FEMALE GENITAL MUTILATION ABANDONMENT AMONG WOMEN IN RURAL COMMUNITIES IN NIGERIA
No full textDespite its cultural importance, FGM has drawn considerable criticism because of its potential for both short- and long-term medical complications, as well as harm to reproductive health and infringement on women’s rights. FGM, according to WHO, (2023) involves the numbing, burning, piercing, partial or total removal of the female external genitalia provokes medical, emotional, social, legal and economic repercussions at all levels of society; and many survivours of FGM often have to endure the negative effects of the practice to their sexual, reproductive health and overall wellbeing. Over the years, world leaders, international and national organisations and Non-Governmental Organisations have put a lot of effort and resources into ending FGM which is internationally recognised as a violation of human rights, and an extreme form of violence against girls and women.

No full textThe development of Augmented Reality (AR) for learning Geographical Information System (GIS) involves several challenges pertaining usability. Thus, this study conducted usability assessment during development of AR package for learning GIS (ArGIS) for undergraduate students in Gombe State, Nigeria. The study was based on design and development using pre-test and post-test. The population for the study comprised 194 undergraduate students from two universities in the state. The participants were purposively sampled using two intact classes of 84 in experimental group and 110 in control group. A sample of 15 experts from Instructional Design, GIS and Computer Science were involved in the study. A 3rd version Post-Study System Usability Questionnaire (PSSUQ) widely used in Human Computer Interaction (HCI) was adopted for the study. The PSSUQ was a standardized tool with 0.90, 0.91 and 0.83 reliability coefficients for system usefulness, information and interface quality respectively. The PSSUQ was administered both during and after development of the package. The findings revealed that the ArGIS was rated 94.875% and 97.35% usable by experts and students respectively. The study concluded that usability assessment of mobile package depends on the users, their characteristics and skills, the task they want to perform as well as the context of use. It was therefore recommended that usability assessment should be carried out throughout AR package development process for satisfying the desired learning needs in GIS and remote sensing task

TEACHERS' SELF-EFFICACY AND USE OF DIGITAL TOOLS IN MATHEMATICS INSTRUCTION IN SELECTED SECONDARY SCHOOLS IN ABUJA
No full textDigital tools have become integral devices for teaching and learning in today's education system. The use of digital devices in the classroom has been linked to enhanced student engagement and improved learning outcomes. However, the successful integration of digital devices into the educational process relies heavily on the teachers' self-efficacy. This study, therefore, investigates the teachers' level of self-efficacy and utilization of digital tools in mathematics instruction. The study adopted the descriptive survey research design. The design exploited mostly quantitative approach. Population of the study consisted of one hundred and sixteen (116) teachers from five secondary schools in Bwari Area Council, FCT- Abuja. The Mathematics Achievement Test (MAT) was used to gather data and was verified by professionals. The reliability testing was carried out using Cronbach Alpha to obtain a reliability index of 0.78. Statistics such as mean, standard deviation, and t-test were used to examine the collected data. The data were analyzed using Pearson product-moment correlation coefficient statistics. The findings reveal a significant positive correlation between teachers' self-efficacy scores and their actual utilization of digital tools in mathematics instruction. Teachers who demonstrated higher levels of self-efficacy in using digital tools were more likely to incorporate them into their teaching practices actively. These results highlight the importance of nurturing teachers' self-efficacy beliefs in technology integration. The study emphasizes the need to provide targeted professional development programs and resources to enhance teachers' technological skills and confidence. Empowering educators and fostering their self-efficacy in digital tool utilization can lead to more effective and innovative mathematics instruction. Future research and educational initiatives should continue to explore strategies to enhance teachers' self-efficacy beliefs and investigate the impact of technology integration in mathematics education. The findings of this study contribute to our understanding of the role of self-efficacy in teachers' utilization of digital tools and provide valuable insights for educational institutions and policymakers seeking to promote effective technology integration in mathematics instruction
