ABSTRACT Benue State Tractor Hiring Agency (BENTHA) is usually confronted with the problem of determining the optimum number of tractors to be allocated to different zones in the state. The number of tractors allocated to a zone is normally decided without any proper study of tractor needs of the zones. Sometimes allocation is based on merely political considerations. The problem of allocation is formulated and heuristic procedures are applied to optimally allocate the limited tractors.
ABSRACT Primarily, the project has focused on finding out the Online Buying trends and behavior of Maasai Mara university consumers with an age range of 18- 25 years. The proposed primary objective of the study was further divided into secondary objectives with an aiming of finding detailed information on the research topic. Precisely, information regarding buyer’s buying frequency, average spending, and famous product purchase was gathered. Since the objectives were quantifiable, a quantit...
ABSTRACT The research was conducted to find out whether applying fertilizer to tea at specific season of the year will affect the level of antioxidant. The main objective of the research was to determine the correlation between the level of antioxidant in tea and the season at which fertilizer was applied. Secondary data was obtained from James Finlay Kenya Limited with the authority of Applied Research Department. Trials of NPK fertilizer were conducted during the four seasons of the year: d...
ABSTRACT A measure of dispersion is a statistical tool used to define the distribution of various datasets mainly from measures of central tendency. Some notable measures of dispersion from the mean are; average deviation, mean deviation, variance, and standard deviation. However, from previous studies, it has been established that the aforementioned measures are not absolutely perfect in estimating average variation from the mean. For instance, variance gives estimates which are of different...
ABSTRACT Human Resource Management (HRM) practices will continually attract the attention of researchers in pursuit of better ways to counter the emerging challenges that can undermine the growth of the organizations. The research will be carried out to examine the influence of human resource management practices on the growth of Savings and Credit cooperative societies (Sacco societies) in South Rift Region. The study will examine the relationship among the factor variables which are; select...
ABSTRACT Income accrued from Retirement Benets Fund is an exceptionally important component of every working individual's life cycle globally. The major sources of such income are: unfunded state pensions; funded private pensions; mandatory schemes; and post-retirement work. The urgency and importance has made many countries to give it considerable attention by enacting enabling laws and policies to safeguard it. In Kenya, steps have been made by establishing the National Social Security Fund...
Abstract Trypanosomiasis is a debilitating disease which is a major constraint to livestock production in sub-Saharan Africa. It leads to loss of productivity in animals and without treatment it is frequently fatal. The economic and social repercussions it causes in areas where it is endemic, makes its control a priority operation. In this study we formulate three models; a basic model to understand the transmission dynamics of the trypanosomiasis in a cattle population, a model with treatmen...
ABSTRACT HIV/AIDS epidemic has endangered the development of countries in this new century, presenting one of the greatest challenges of this generation and threatening human development. To accomplish an efficient response requires many researches to find long term solutions. Though its prevalence has declined in the past years, it is still very high in particular regions due to various factors. This research analysed major factors associated with HIV/AIDS prevalence in Maseno Community. If ...
Abstract Economic activities in Lake Victoria Basin such as agriculture, sh- ing, mining and transportation depend's heavily on the climatic conditions of the Lake and its Basin. Global climatic change caused by Greenhouse Gas emission (GHG) has resulted in a disruptive and erratic weather pattern for these economic activities. This unpre- dictable weather variations is responsible for loss of life and destruc- tion of property. The primary cause of this negative impact is lack of a reliable ...
Abstract In this thesis, I investigate the application of various statistical methods towards analysing GPS tracking data collected using GPS collars placed on large mammals in Kruger National Park, South Africa. Animal movement tracking is a rapidly advancing area of ecological research and large amount of data is being collected, with short sampling intervals between successive locations. A statistical challenge is to determine appropriate methods that capture most properties of the data is...
Abstract. This study is a critical review of theoretical issues that underline the linear mixed effects (LME) and nonlinear mixed effects (NLME) models. These two areas are revisited under maximum likelihood and restricted maximum likelihood estimation frameworks. We also review methods of estimating parameters in both linear and nonlinear mixed effects models. In the case of LME, we consider different ways of developing the likelihood estimators, key among these methods are the “pseudo-dat...
Abstract This study set out to examine and map the spatial variation of infant mortality in Kenya. We used data from Demographic and Health Survey (DHS) database to explore spatial variation. Generalized linear mixed inodel(GLMM) with Enumeration Areas (EA) specific random effects was used to assess the effects of geographical heterogeneity and other covariates. The model based Geostatistical methods were used to quantify the spatial variations of the observations using the variograms and fit...
ABSTRACT Contraception allows women and couples to have the number of children they want, when they want them. This is everybody’s right according to the United Nations Declaration of Human Rights. Use of Contraceptive also reduces the need for abortion by preventing unwanted pregnancies. It therefore reduces cases of unsafe abortion,one of the leading causes of maternal death worldwide.According to Mohammed ,in 2012 an estimated 464,000 induced abortions occurred in Kenya. This translates ...
ABSTRACT Education progress plays a very important role in determining the future of a pupil and even in planning for the schools and education sector as a whole. Primary Education forms the basis of implementing Poverty Reduction Strategy by the government through the acquisition of basic literacy skills, which increases opportunities for employment and ability to be self-reliant, hence the need to monitor the pupils general progress from the time of entry in class one to graduation after th...
ABSTRACT Tea production is the mainstay of many people in Kenya. The contribution of tea sector to the Kenyan economy is enormous as it accounts for about 4% of Gross Domestic Product (GDP). Favourable product prices act as a trigger for any commercial activity over time and also suggest sustainability of the activity. Tea is a very significant crop in Kenya and it is one of the major agricultural exports of the country. However, the industry has experienced many challenges such as stiff comp...
