The implementation of corporate environmental management system has become an essential part of running any business to attempt to achieve sustainable development. No previous studies in Saudi Arabia have been conducted to explore the use of environmental management systems. The objective of...

Nigeria is one of the countries most affected by the HIV/AIDS pandemic, third only to India and South Africa. With about 10% of the global HIV/AIDS cases estimated to be in the country, the public health and socio-economic implications are enormous.This thesis has two broad aims: the first is to...

Scotland is entering a transition period for its environment and economy as it decides which path to follow in meeting its energy and electric power needs over the coming decades. This thesis describes and evaluates several of the major dimensions which will contribute to those decisions and see...

This thesis aims to develop the foundations for a new validation strategy for route-based road weather forecasts that will enable validation of route-based models at a vastly improved spatial and temporal resolution, and in doing so provide a tool for rapid appraisal of new model...

Many medical studies involve modelling the relationship between an outcomevariable and a series of one or more continuous/interval scaled discrete explanatoryvariables. It is common practice in many of these studies for some, or indeed all, ofthe continuous/interval scaled discrete explanatory...

The stopping rules in sequential methods have posed a lot of difficulties inanalyzing the efficiencies of sequential procedures. The exact distributionsof the stopping points and the statistics related to those stopping rules arehardly available explicitly. Woodroofe (1976), (1977), Lai and...

This thesis develops several Generalized Method ofMoments (GMM) estimators for analysing Not Missing at Random (NMAR) data, which is commonly referred to as the self-selection problem in an economic context. We extend the semiparametric estimation procedures of Ramalho and Smith (2003) to...

The aim of this thesis is to investigate Generalised Empirical Likelihood (GEL) and related informational theoretical methods for estimation and inference of parameters of models that satisfy unconditional and conditional moment restrictions. Three topics in this field are studied. Firstly, the...
