ABSTRACT The study attempts to determine whether the mood of teachers have any direct bearing on the academic performance of students in class. The study area was Morso D/A J.H.S. A sample size of forty students from form two was used for the study. The affect theory by Tomkins and the behavioral theory by Bandura was adopted as framework for this study. The random sampling technique was employed to select the samples into two groups of students each comprising of twenty, the groups were tau...
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...
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...
ABSTRACT BACKGROUND: Developing countries including Namibia are experiencing a rapid increase in non-communicable diseases. Blood pressure is estimated to instigate round about 60 percent of deaths around the world, of which 80 percent occur in developing countries.
Abstract The accident risks of drivers and the factors affecting the risks were analyzed using survival models. The data consisted detailed records of fatal accidents in the years 2007 - 2009, generated by the Motor Traffic and Transport Unit (MTTU) of the Ghana Police Service, Northern region. The data on fatal accidents contained 398 drivers. The objectives of the study included both analysis and explanation of driver accident risk factors and investigation of how survival modeling method ...
Abstract Motor Vehicle Traffic Crashes (MVTC) are one of the leading causes of death and disability in the world, especially in developing countries. Despite Namibia having a well- developed road network, MVTC are the third highest cause of death in the country with 23.9 per 100 000 MVTC fatality rate recorded. This study was conducted in Namibia to model factors affecting the severity of injuries from MVTC. The study purpose was to examine the effects of human, crash/accident types, environ...
Abstract -. "Since. statisticians do not usually perform an experiment, their claim to attention when they write on experimentation requires some explanations", William Cochran and Gertrude Cox (1957). Block designs are widely used in many fields of research. Their most common type is the randomized (complete) block design. It is not applicable in all circumstances. If the numbers of (elements are too large to preserve homogeneous conditions within complete blocks or the sizes of blocks are d...
ABSTRACT This study examines exchange rate volatility with Generalised Autoregressive Conditional Heteroscedastic (GARCH) models using monthly exchange rate data from the bank of Ghana from January 1990 to November 2013. The data was converted to returns to enhance their statistical properties and the returns used to fit a mean equation. The ARCH LM test of the mean equation revealed the presence of conditional heteroscedasticity. The returns were therefore modeled using ARCH (3), GARCH (2,3)...
ABSTRACT Poverty amongst elderly persons is a phenomenon experienced worldwide, Namibia included. The government of Namibia has come up with various social safety nets programmes which include old age pension, disability grant and child maintenance grant to alleviate poverty. Although these interventions were introduced to reduce poverty among the targeted groups, statistics reveal that poverty still exists amongst those receiving old age pension. The aim of the study was to examine factors ...
Abstract Fingerprint emerged as an important system within the security agencies, government offices and court of law in the late 19th century, when it replaced anthropometric measurements as a more reliable method for identifying persons. No two fingerprints have ever been found identical in billions of human and automated computer comparisons. Fingerprint is thus claimed to outperform DNA and all other human identification systems. However, genetic mutation and effect of certain drugs have...
ABSTRACT The research is based on financial time series modelling with special application to modelling inflation data for Ghana. In particular the theory of time series is explored and applied to the inflation data spanning from January 1965 to December 2012 which were obtained from the Ghana Statistical Service. Three Autoregressive Conditional Heteroscedastic (ARCH) family type models (traditional ARCH, Generalized ARCH (GARCH), and the Exponential GARCH (EGARCH)) models were fitted to the...
ABSTRACT The study focused on the assessment of stakeholders participation as a determinant for effective land use plans implementation in the Tamale Metropolis of Northern Region of Ghana. Primary data was then collected from households and institutions and analyzed. The study revealed that those factors such as leadership qualities, transparency, resources availability and centralization of decisions affect successful stakeholders’ participation in implementation of land use plans. The ...
ABSTRACT Acute respiratory infection (ARI) range, in spectrum, from mild colds and coughs to life threatening pneumonias. ARI particularly pneumonia is the major cause of morbidity and mortality among young children under five in developing countries with Ghana not an exception. In this study, we compared the linear SARIMA Model and the nonlinear two regime SETAR Model in predicting pneumonia cases in northern region of Ghana. Data on monthly pneumonia cases obtained from the Tamale Teachin...
ABSTRACT This thesis investigates the Application of Queuing theory to customer services at selected branches of the Standard Chartered Bank in Accra. The problem investigated was to determine among other things whether the customer service points of the bank functions well without bottlenecks or undue delays. That is this thesis intends to investigate, (a) If the bank current system of operation at the customer service points is satisfactory. (b) If not what changes are required to improve t...
ABSTRACT Acquired Immune deficiency Syndrome (AIDS) is a disease caused by a virus known as Human Immunodeficiency virus (HIV). This virus attacks a person's immune system (white blood cells) and as such weakens the immune system and making the person vulnerable to opportunistic diseases e.g. tuberculosis, diarrhoea, to mention a few. HIV was first diagnosed more than twenty years ago and up to now there is no known cure for the disease. The rate at which HIV is spreading in sub-Sahara ...
