Determinants of Child Mortality and Morbidity in South Sudan.

ABSTRACT  The main objective of this study was to examine factors associated with childhood mortality and morbidity in South Sudan. The specific objectives were to establish childhood mortality, examine the effect of childhood factors on morbidity as well as examining the contribution of mother factors on childhood mortality and morbidity. The study used both descriptive and inferential analysis using secondary data from Second South Sudan household health survey (SSHHS2). Using univariate, ...

Five Child-killer Diseases and Under-five Mortality in Yola Adamawa State, Nigeria (2001-2015)

Abstract The study was set out to investigate the prevalence of the five-child killer diseases and its cause effect on under-five mortality. It was driven by four major objectives; Determining the prevalence rate of the five child-killer diseases; Determining the proportion of mortality due to the five child-lciller diseases to the total under-five mortality in the studying area; Examining the correlation between the five child-killer diseases and under-five mortality and Determining the caus...

Seven-Factor Central Composite Design Robust to a Pair of Missing Observations

ABSTRACT In this work, the seven-factor central composite design () is studied in respect of a pair of missing values using the minimax loss criterion. It was observed empirically that seven-factor central composite design with k = 7 , = 128 f n , = 14 a n , = 3 c n and n = 145 is robust at a = 2.6 and variance robust at a = 2.45. We also observed that the loss effect of missing a pair of factorial points is a decreasing function of increasing a , while the loss effect of a pair of axial poin...

Integer Programming approach to Staff Scheduling of Resource Persons to a Polytechnic: A case study of NBTE’s Accreditation team

Abstract In this work,we applied an Integer Programmingapproach to schedulingof resource persons on National Board for Technical Education (NBTE) accreditation team to a Polytechnic. The level of compliance of the institution to national minimum benchmark for academic standards with respect tostaff mix was deduced.The use of Integer Programming approach and Lingo software in solving the model developed, resulted in considerable drop in accreditation cost from four million, seven hundred and f...

Methodological Models for Optimal Control of Marine Oil Spill

Abstract The frequency of accidental discharge of oil into aquatic environment has presented a significant threat to marine biota with related adverse effects on the supply of products and services of importance to human cultures. This threat of economic and environmental devastation led to the development of a number of monitoring and clean-up alternatives such as remote sensing and chemical dispersants, respective. This study proposed a new possible research direction in marine oil spill mo...

On Optimal Complete Replicated Rotatable, Orthogonal, Efficient and Relative Efficient Central Composite Designs

ABSTRACT Replication is the repetition of the treatments under investigation to different experimental unit. Replication is essential for obtaining a valid estimate of the experimental error and to a greater extent, increasing the precision of estimating the pairwise difference among the treatment effects. It is on this note that when full replication (replication of cube and star point) is made, there exists need for optimal replication for the purpose of minimizing biasedness. Some variatio...

Agricultural Production and Economic Growth in Somalia from 1986 to 2016

ABSTRACT The study aimed at examining the effect of agricultural production on economic growth in Somalia from the period of 1986 to 2016 using time series data. Specifically, the study examined the causality and the effect of agricultural production on GDP growth. The objective was motivated by the fact that the problem statement emphasized that agricultural production has not yielded expected economic growth in Somalia. The study hypothesized that no casualty between agricultural production...

Determinants of Maternal Mortality of Somalia in the Period 1990 to 2012

ABSTRACT This study investigated the influence of gross domestic product per capita, total fertility rate and HIV/AIDS prevalence rate (termed as determinants) on maternal mortality of Somalia in the period 1990-2012. This model is dedicated from demographic transition theory-derived from modernization theory. Secondary data between 1990 and 2012 inclusive collected from the publications of United Nations Statistics Division (UNSD) and World Health Organization (WHO) was used for this study. ...

Population Growth and Youth Unemployment in Somalia (1991-2017)

ABSTRACT he purpose of the study was to investigate the relationship between the population growth and youth unemployment in Somalia. The specific objectives of the study were; to examine the long-run relationship, causation, and effect of population growth on youth unemployment rate. The study used a descriptive, correlation and longitudinal design and only employed the Quantitative research approach. L~ie study was carried out using secondary 4ata collected from 1991 to 2017. Augmented Dick...

Health Service Delivery and Maternal Survival at Banadir Hospitals for 2001 — 2010 in Mogadishu, Somalia

Abstract This study was set out to establish the relationship between health service delivery and maternal survival at Banadir hospitals for 2001 up to 2010 in Mogadishu, Somalia the study wanted to establish the foUowing to determine the trend and level of health service delivery for 2001 to 2010 at Banadir Hospitals, to establish the trend and the level of maternal survival-for 2001 to 2010 at Banadir Hospitals, and to investigate the relationship between the health service delivery and mat...

Assessing the Effects of Geographical Expansion of Consumer Price Index on Inflation in Uganda

ABSTRACT  This study details the effects of increasing Consumer Price Index (‘CPI,) geographical coverage on inflation in the country. The study looked at the level 0/significance of Headline inflation and its related components, bejbre and a/icr geographical coverage increment. A comparison ofanalytical results obtained with two diffrreni CPI coverage, inflation numbers with Fort Portal Centre included in the computations and inflation numbers without Fort Portal Centre. The study applied...

Private Sector Investment and Economic Growth in Uganda (1985-2014)

ABSTRACT The study aimed at examining the effect of private sector investment on economic growth in Uganda from the period of 1985 to 2014 using time series data. Specifically, the study examined the casuality, the long-run relationship between private sector investment and economic growth and also the impact of private sector investment on GDP growth. The objective was motivated by the fact that the problem statement emphasized that private sector investment has not yielded expected economic...

Population Growth and Youth Unemployment in Somalia (1991-2017)

ABSTRACT The purpose of the study was to investigate the effect of population growth on youth unemployment in Somalia from 1991 to 2016. The specific objectives of the study was to examine the long-run relationship, causation, and effect of population growth on youth unemployment rate. The study used crosssectional and longitudinal research design for the data obtained from World Bank where stationarity test was conducted using ADF tests prior to estimation.
