ABSTRACT The deficit of domestic fish supply necessitates importation of frozen fish to supplement protein intake of Nigerians. Adequate quality standards and control measures are in place for frozen fish at the point of entry to the country. However, there is dearth of information on quality control along the distribution chain to the final consumer. Therefore, quality and handling procedures of imported frozen fish within Oyo State were investigated. Three-stage sampling procedures were us...
Abstract The COVID-19 pandemic has had a profound impact on global health and has highlighted the importance of understanding the transmission dynamics of infectious diseases. This study aimed to construct a COVID-19 transmission matrix in Kenya using the Markov chain and to examine the equilibrium distribution and steady states for COVID-19 transmission in Kenya. The study utilized data from the Ministry of Health in Kenya and other sources to estimate the transition probabilities used in t...
Abstract/Overview Volatility is the measure of how we are uncertain about the future of stock or asset prices. Black-Scholes model formed the foundation of stock or asset pricing. However, some of its assumptions like constant volatility and interest among others are practically impossible to implement hence other option pricing models have been explored to help come up with a much reliable way of predicting the price trends of options. The measure of volatility and good forecasts of futu...
ABSTRACT Contaminated milk is responsible for up to 90% of all dairy-related diseases of humans. A cross sectional study was carried out in Lushoto and Handeni districts of Tanga, Tanzania to determine the milk handling practices, bacterial contamination and selected milk-borne zoonotic pathogens along the dairy value chain. A total of 93 respondents were interviewed and 184 milk and milk product samples were collected. Laboratory analysis of total and coliform plate counts, detection of Esc...
Traditional processed camel meat (Nyirinyiri) is a ready to eat meat product prepared traditionally from dehydrated camel meat that is deep fried in fat. The processed product is stored in the same fat and consumed little by little as required because of its long shelf life with desirable taste which pastoral households use in their diets, snack or sell for income. This study analyzed the biochemical, chemical and nutritional status of camel Nyirinyiri from production area in Isiolo Coun...
ABSTRACT Background: Routine empiric antibiotic therapy is common in patients living with HIV/AIDS. Such routine antibiotic regimen could lead to selection of multidrug resistance especially ESBLs in hitherto drug sensitive intestinal colonizing flora. There is paucity of data to describe intestinal carriage of ESBL-producing enterobacteria in HIV/AIDS patients. Aim: This study was designed to examine HIV/AIDS patients for faecal carriage with extendedspectrum beta-lactamase producing enterob...
Abstract Background. Giardia duodenalis causes sporadic or epidemic infections in humans. The parasite comprises assemblages A-H with A and B subdivided further into AI-IV and BI-IV subassemblages. Attempts aimed at linking these genotypes with sources and gastrointestinal manifestations of the infection are largely unexplored in rural communities. Methods. In this cross-sectional study, G. duodenalis infection was genotyped and associated with sources, and gastrointestinal signs and symptom...
ABSTRACT The poor are not evenly distributed within the country and they do not share the same socio-economic and demographic characteristics. It is against this background that analysis of the characteristics that differentiate the poor from the non-poor in Ghana cannot be underestimated. Poverty indicators make it possible to analyze the likely determinants and are, therefore, essential for formulating policy interventions that may contribute directly or ...
ABSTRACT The purpose of this study was to explore the management and coping strategies of hypertensive patients seeking treatment at Brong Ahafo Regional Hospital, and to examine participants’ experiences of living with the condition. A mixed method design was used and all 508 consenting patients were selected for the quantitative aspect, and 16 were conveniently sampled for the qualitative one. Instruments (questionnaire and in-depth interview guide) derived from five pre-existing ones wer...
Abstract This paper describes the socioeconomic determinants of primary school dropout in Uganda with the aid of a logistic model analysis using the 2004 National Service Delivery Survey data. The Objectives were to establish the; household socioeconomic factors that influence dropout of pupils given free education and any possible policy alternatives to curb dropout of pupils. Various logistic regressions of primary school dropout were estimated and these took the following dimensions; rural...
ABSTRACT Malaria is a major contributor of ill health and death particularly among infants and pregnant women in sub-Saharan Africa. The infected erythrocytes sequester in the placenta and may be present throughout the whole pregnancy period. Although microscopy is the gold standard method currently acceptable in diagnosis of malaria in hospital, it is unreliable because during pregnancy, malaria parasites disappear from peripheral circulation and remain undetectable through microscopic exami...
Abstract Evaluation of customer satisfaction differs from one study to another. Studies have been differing with their focus and coverage. Most of studies focused on evaluating factors influencing customer satisfaction or associate customer satisfaction and quality of services. This paper used logistic regression to develop customer satisfaction model for Precision Air. Five dimensions or variables have been considered: on time performance; aircraft safety; schedule integrity; on board servi...
Abstract: We present a new class of distributions called the Topp-Leone-G Power Series (TL-GPS) class of distributions. This model is obtained by compounding the Topp-Leone-G distribution with the power series distribution. Statistical prop erties of the TL-GPS class of distributions are obtained. Maximum likelihood estimates for the proposed model were obtained. A simulation study is carried out for the special case of Topp-Leone Log-Logistic Poisson distribution to assess the performance o...
ABSTRACT Sweet potato with a negligible amount of vitamin A has been consumed for a long time in Sub-Saharan African (SSA)countries including Tanzania. The production and consumption of improved sweet potato varieties including orange fleshed sweet potato (OFSP) with high Vitamin A content has been promoted due to its potential to combat Vitamin A Deficiency (VAD). Adding value to OFSP will increase both its shelf-life and market demand. This study was conducted toassess consumer acceptabilit...
ABSTRACT Several strategies have been put in place in an attempt to reduce childhood mortality in Ghana, however the proportions of death among neonates are still quite high. The study therefore seeks to model neonatal mortality using survival analysis approach. The data used for the study was obtained from the neonate’s folders at St. Jude Hospital in Obuasi in the Ashanti Region between January 1, 2012 and December 31, 2015. Data on maternal characteristics was also obtained. Neonates who...
