The Impact Of Food Insecurity On Quality Of Life In Windhoek Informal Settlements: A Structural Equation Modelling

ABSTRACT Namibia is experiencing an increase in its population living in urban areas due to rapid urbanisation. However, this growth has not been the same in all parts of the country. Currently the biggest growth rate is experienced in Windhoek, which is home to about 16% of the total population. Due to rapid population growth, Windhoek has been facing a number of challenges such as high unemployment rate, illegal land occupation, and development of informal settlements among others. As a res...

Modeling Of Road Traffic Fatalities In Namibia: A Generalized Linear Model Approach

Abstract Fatalities caused by road traffic accidents have become a major concern worldwide and road traffic accidents happen almost every day on Namibian national roads claiming lives of many road users. It is predicted that by 2030, road crash fatalities would be the fifth most frequent cause of death worldwide. Many efforts have been made to prevent loss of lives and to curb down the MVA expenses on compensations due to road traffic accident; however, road traffic fatalities are still on th...

Shared-Component Model With Application To Mapping Gender Specific Pattern In Hiv Testing And Condom Use In Namibia

Abstract The main objective of the study was to examine gender-specific and shared spatial variation in HIV testing and condom use in Namibia for targeted health promotion interventions. The study used data from the Namibia Demographic and Health Survey (NDHS) carried out between 2006 and 2007. Bayesian hierarchical spatial mapping techniques were applied to generate specific and shared spatial patterns in HIV testing and condom use. Particularly, a number of Bayesian Structured Additive Regr...

Head Tilt Classification Using Fft-Pca/Svm Algorithm

ABSTRACT The complexity of a face’s components originates from the constant variations in the facial component that occur with respect to time. Notwithstanding these variations, humans recognize a person very easily using physical characteristics such as face, voice, gait, etc. Automatic face recognition deals with extracting these essential features from an image, placing them into a suitable representation and performing some kind of recognition on them. This study presents an assessment...

Statistical analysis of socio-economic determinants on child labour and schooling in ghana.

ABSTRACT The objective of this study was to find the socio-economic determinants of child labour and schooling in Ghana. To this end, the 2003 Ghana Child Labour Survey data was analysed. The main techniques used were the simple logistic regression and multilevel logistic regression analysis. Results of the analysis showed that gender of head of household, marital status of parents, father’s occupation, mother’s occupation, relationship to head of household, place of residence, literacy ...

Infant And Child Feeding Practices: Analyses Of Exclusive Breastfeeding And Complementary Feeding In Namibia

ABSTRACT Malnutrition remains a factor, directly or indirectly, in 60% of 11 million deaths of children aged less than five years globally each year. Hence, proper nutrition during infancy and early childhood is fundamental to the development of a child’s potential for normal growth, development, and survival of infants and children, particularly in developing. This study intent was to examine feeding patterns, practices and factors associated with exclusive breastfeeding and complementary...

Food insecurity and quality of life in informal settlements of Katutura, Windhoek, Namibia.

ABSTRACT  Globally, with rapid urbanization in most cities of the World, more people are now living in urban areas than in rural areas. The housing backlog coupled with a shortage of housing subsidies means that for many there is no alternative but to live in informal settlements. Urban food insecurity is often overlooked since, at the aggregate level, economic and social conditions in urban areas are much better than those in rural areas. The urban poor often live in neighbourhoods with poo...

Zero-Augmented Models For Exploring The Factors Affecting The Pass Rate Of Grade 10 Learners In Khomas Region In 2016

ABSTRACT The poor performance of grade 10 learners has been a big concern over the last few years and in the effort to understand this phenomenon there has been efforts to present models that explain it. Modelling semi-continuous data with the presence of excess zeros has become a common phenomenon in real life situations. Common models such as linear models cannot handle zero-inflated data. This study aimed at exploring the factors which influence Khomas Region grade 10 learners’ pass rat...

The Application Of Multivariate Statistical Techniques In The Analysis Of Stock Market Data

Securities were first traded in the sixteenth century and it is reasonable to assume that si~ce that time investors have always devoted attention to research into the relative merits and demerits of individual stock market ventures. In the nineteenth and twentieth centuries, ma~ has placed increasing emphasis on numerical and statistical analysis, and it was only a matter of time before these two related approaches focussed their attention on the problems of stock market research. As early as...

Understanding and Supporting Pricing Decisions using Multicriteria Decision Analysis: An Application to Antique Silver in South Africa

Abstract This dissertation presents an application of multicriteria decision analysis to understand and support pricing decisions in fields where goods are unique and described by their characteristics. The specific application area of this research is antique silver objects, where a complete iteration of the multicritia decision process is performed. This includes two problem structurings using SODA which provide rich detail into this application area. Multi-attribute additive models are con...

Sequential Nonparametric Estimation via Hermite Series Estimators

Abstract Sequential Nonparametric Estimation via Hermite Series Estimators Michael Jared Stephanou Algorithms for estimating the statistical properties of streams of data in real time, as well as for the efficient analysis of massive data sets, are becoming particularly pertinent given the increasing ubiquity of such data. In this thesis we introduce novel approaches to sequential (online) estimation in both stationary and non-stationary settings based on Hermite series density estimators. In...

Complementary Power Series Exponentiated Nadarajah-Haghighi Distribution

ABSTRACT   A new class of distributions, called complementary power series exponentiated Nadarajah-Haghighi distribution was developed in this study by compounding the exponentiated Nadarajah-Haghighi distribution with zero truncated power series distributions. The new class of distributions were developed using the concepts of latent complementary risk scenario, in which the lifetime associated with a particular risk is not observable; rather we observe only the maximum lifetime value amon...

Multiscale Spatial Modelling Of Diabetes And Hypertension In Namibia

ABSTRACT In Namibia, non-communicable diseases are on the increase. Statistics on noncommunicable diseases (cancer, diabetes, cardiovascular diseases, hypertension etc.) as a cause of morbidity and mortality indicate that it is a public health concern although population based estimates in the area are lacking. The Ministry of Health and Social Services stated that between 2004 and 2008, hospital based mortality due to cancer (all types) increased from 3.2% to 54.7%, cardiovascular diseases ...

A Statistical Approach To Automated Detection Of Multi-Component Radio Sources

Abstract Advances in radio astronomy are allowing for deeper and larger observations than ever before. Source counts of future radio surveys are expected to number in the tens of millions. Source finding techniques are used to identify sources in a radio image, however, these techniques identify single distinct sources and are unable to identify multi-component sources, that is to say, where two or more distinct sources belong to the same underlying physical phenomenon, such as a radio galaxy...

Survival And Prognostic Factors Of Hiv/Aids, Tb And Co-Infection In Pru District

ABSTRACT Survival analysis is a method for analysing the occurrence of a given event. This research seeks to evaluate the survival of HIVIAIDS, TB and co-infected patients and to identify the major prognostic factors that influence their survival. In this study, survival data for HIV/AIDS, TB and HIVITB co infection patients were obtained from St. Mathias Hospital in Yeji, Pru District of Brong Ahafo Region of Ghana. The data was fitted using both the Cox model and accelerated failure time mo...
