  • Two-Stage Artificial Neural Network Regression Modelling for Wheezing Risk
           Factors Among Children - A Case Study of Gatundu Hospital, Kenya

    • Authors: Thomas Mageto; John Onyango
      Pages: 38 - 47
      Abstract: In Kenya wheezing that leads to asthma development in most cases remain under-diagnosed and under-treated. Currently there is no public supported wheezing and asthma care programmes to optimize care for patients with asthma which greatly compounds diagnosis and treatment of the disease. The aim of this study is therefore to consider and analyse the covariates of childhood wheezing among children below 10 years of age in Kenya, a case study of Gatundu hospital in order to improve the provision of wheezing and asthma care services in medical facilities. The possible risk factors in the study are selected from three major groups of demographic, socioeconomic and geographical location factors related to childhood wheezing. The longitudinal secondary data obtained from Gatundu hospital in Kenya were collected and a total of 584 complete cases were recorded. The predictor variables considered in the study include age of children in months, gender, exclusive breastfeeding, exposure to tobacco smoking, difficult living conditions, residence, atopy, maternal age and preterm births. Due to the binary nature of response variable in which data is recorded as presence or absence of wheezing, the risk factors were modelled using multiple logistic regression and Artificial Neural Network Models. Simple random samples of sizes n = 385 without replacement were selected and p-values at 5% level of significance for the variables were recorded. In multiple logistic regression, the five variables identified as possible risk factors for modelling with p-value less than or equal to 0.05 were selected that includes age of children, exclusive breastfeeding, exposure to tobacco smoking, difficult living conditions and residence that recorded p-values of 0.0151, 0.0000, 0.0071, 0.0274 and 0.0410. The best multiple logistic linear regression model selected was based on Akaike Information Criterion (AIC) criterion that recorded null deviance, residual deviance and AIC of 502.44, 179.57 and 191.57 respectively. The precision and accuracy of the multiple logistic regression model were recorded as 89.2% and 93.3% respectively. The Artificial Neural Network was considered for modelling as well, the model with one-hidden layer with four neurons in the hidden layer recorded precision of 97.1% and accuracy of 39.4% while the rest of the models with one hidden layer recorded precision and accuracy of 0.0% and 65.1% respectively. The Artificial Neural Network model with two-hidden layers were also considered and the Network with one neuron in both layers was selected as better performing model with precision and accuracy of 88.2% and 93.3%. The developed two-stage logistic Artificial Neural Network was found to have better performance compared to multiple linear logistic regression and Artificial Neural Networks since it recorded precision and accuracy of 97.1% and 99.0% respectively and hence recommended for consideration in modelling the risk factor of wheezing among children in Kenya.

  • Generalised Rational αs-Meir-Keeler Contraction Mapping in S-metric
           Spaces

    • Authors: Shanu Poddar; Yumnam Rohen
      Pages: 48 - 52
      Abstract: In this paper, we introduce the concept of generalised rational αs-Meir-Keeler contraction mapping on S-metric spaces. The existence of fixed points is also discussed.

  • On the Applications of Ricatti Differential Equations to Some Special
           Cases of the Two-Body Problem with Variable Masses

    • Authors: Ilhan M. Izmirli
      Pages: 53 - 56
      Abstract: In this paper, we obtain the solution of the two-body problem with variable masses by posing some assumptions on the classical equation and thereby reducing the solution of the problem to investigating the solutions of some Ricatti type differential equations. Along this process, we also give a simple proof of the well-known Mestscherskii Theorem and establish some related formal relations under these assumptions.

  • Post Hoc Analysis of Life Expectancy in West Africa

    • Authors: Jonathan Iworiso
      Pages: 57 - 65
      Abstract: This paper investigates the effect of country, gender and the associated interaction term on life expectancy in West African countries. The empirical analysis revealed that country and gender have statistically significant effect on life expectancy in West Africa, while the associated interaction term has no significant effect on life expectancy. Thus the removal of the nuisance interaction term seems to improve the predictive task of the statistical model. The empirical findings in this paper revealed that Cape Verde has the highest average life expectancy among all the West African countries, which also ranks highest in the United Nations index of West Africa. The Tukey HSD tests provide statistically significant differences between countries with higher life expectancy and countries with lower life expectancy. This accounts for the variation in life expectancy between the West African countries. Contrary to the notion in some previous reports which believed that countries with higher GDP tend to have a higher life expectancy, and that the difference in life expectancy per difference in GDP per capita is higher for poorer than for richer countries; this paper reveals that most West African countries endowed with natural resources resulting to higher GDP tend to have lower life expectancy.

  • Common Fixed Point of Generalized αs-ψ-Geraghty Contractive
           Mappings on b-metric Spaces

    • Authors: Jianju Li; Hongyan Guan
      Pages: 66 - 74
      Abstract: In this paper, we study the existence and uniqueness of common fixed point of generalized αs-ψ-Geraghty contractive mapping in the framework of b-metric spaces. We give an example to prove the validity of our conclusion.
