ABSTRACT Tungiasis is a parasitic skin disease caused by sand flea Tungapenetrans. The disease is endemic in Latin America, the Caribbean and Africa.In Kenya, little data has been published regarding tungiasis generally. In Nambale health centre, tungiasisaccounted for 4% of total morbidities at the outpatient department. The prevalence of tungiasis among residents of Musokoto sub-location, the risks factors associated with tungiasis infestations and treatment methods used by Musokotoresident...
Abstract Diagnosing cardiac diseases by using an advanced statistical classifying model is vitally important for cardiac diseases which are viewed as serious diseases which can put an end to a patient’s life, therefore, early diagnosis should be done through classification and to differentiate among the cardiac patients and non-cardiac ones based on the factors that can cause the cardiac diseases by using technologies such as logistic regression and discriminative analysis. This study aime...
Abstract Tuberculosis (TB) is one of the most important public health problems in Tanzania and was declared as a national public health emergency in 2006. Community and individual knowledge and perceptions are critical factors in the control of the disease. The objective of this study was to analyze the knowledge and perception on the transmission of TB in Tanzania. Multinomial Logistic Regression analysis was considered in order to quantify the impact of knowledge and perception on TB. The ...
Abstract Over the last decade major global efforts mounted to address the HIV epidemic has realized notable successes in combating the pandemic. Sub Saharan Africa (SSA) still remains a global epicenter of the disease, accounting for more than 70% of the global burden of infections. Despite wide spread use of various intervention strategies that act as mediation factors in Human Immunodeficiency Virus (HIV) prevention, HIV prevalence still remains a challenge especially in some geographic ar...
Vegetation-environment (soil) was studied in fallow plots in Uyo, ranging from 0-year-old to 6-year-old. Systematicsampling method was used to sample both vegetation and soil. The parameters determined for vegetation included; Height,Frequency, Basal area and Crown cover for all species. The soil physical and chemical properties were also determined.Results obtained showed that there were eight (8) plant species in the 0-year old plot, 12 species in the 2-year old plot,20 species of plants in...
ABSTRACT Effective supply chain management (SCM) has become a potentially valuable way of securing competitive advantage and improving organizational performance since competition is no longer between organizations, but among supply chains. This research conceptualizes and develops three dimensions of SCM practice (strategic supplier partnership. customer relationship, information sharing.) and tests the relationships between SCM practices. competitive advantage, and organizational performanc...
ABSTRACT Differential Item Functioning (DIF) is the different probability of responding to a test item by individuals with the same ability level, but from two different groups. The groups may be based on gender, race or disability. DIF can be detected by methods such as Mantel-Haenszel (MH) and Logistic Regression (LR) which classify DIF items into negligible, moderate, and large DIF. Conditions such as Sample size, Ability distribution and Test length may have a significant effect on DIF de...
ABSTRACT Issues of international borders have been of security concern to governments particularly, in the post 9/11 era. The securitization discourse has taken centre stage as governments move towards tightening their border controls against ‘perceived threats’ such as terrorism. Many African countries face the difficult task of securing their borders. Numerous challenges encountered in this regard means that borders have become transnational crime zones. In recent times, transnational s...
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 As a result of poor performance in statistics introductory course among the students in the universities; the study wanted to find out the factors that influence the performance of students. The purpose of the study was to conceptualize and empirically test ordinal logistic model on the factors affecting students’ statistics performance in public universities. Students’ performance was indicated by the grades they scored in the past statistical courses they undertook. The predict...
Abstract/Overview Differential equations have been used to create mathematical models of real world systems in which rates of change are involved, for example in the study of how population grows or shrinks. One of the earliest models by Thomas Malthus has been found to be unrealistic since it predicts that population will grow exponentially and without bound – a prospect that defies physical limitations. Verhulst in his logistic population model developed a generalized version of the M...
ABSTRACT Human resource management is one of the most important practices which help to ensure retention of staffs in organisations. The National Disaster Management Organisation (NADMO) in Ghana has been under intense pressure by citizens to revamp their workforce in order to achieve high performances. However, the institution has failed to be proactive in its responses to disaster management in the country. This study therefore examines the effect of employee turnover on performance of NAD...
ABSTRACT This research was designed to investigate the factors affecting efficacy of assessment centres in assessing children with special educational needs in Winneba, Hohoe and Accra centres. One of the major research questions that guided the study examined the material and logistics used in assessing children with special educational needs in the assessment centres. One hundred and twenty respondents sampled took part in the study. Structured questionnaires and interview guide were used t...
ABSTRACT In this article, a time truncated life test based on two-stage group acceptance sampling plan is proposed for lifetime of an item follows odd generalized exponential log-logistic distribution (OGELLD). The ability about the lot acceptance can be made in the first or second stage according to the number of failures from each group. The optimal parameters for the proposed plan are determined such that both producer’s as well as consumer’s risks are contented simultaneously for the...
Abstract Pharmaceuticals together with salaries consume 60-80% of the health budgets of most counties in Kenya, therefore improving performance of the pharmaceutical commodity supply chain is one of the key activities aimed at improving health systems in Kenya. An efficient supply chain system reduces wastage and ensures availability of and accessibility to essential medicines, namely the right product in the right quality, in the right condition, at the right place, at the right time and a...
