The Kingdom of Saudi Arabia (KSA) has experienced increase in health expenditure and the demand for healthcare services. Health statistics indicate inefficiency in resource utilization within the healthcare system, particularly in the hospital sector. This thesis assessed the ef…
The study began with the understanding that knowledge management is critical but presents a challenge to accurately measure the outcome of individual knowledge management and at the same time distinguishes the various activities that attribute to knowledge management. The resear…
The last decade witnessed the rapid increase in the interest of the cesium lead halide perovskites (Cs-LHPs) and their successful applications in optoelectronic devices and photovoltaics. Increasing interest in perovskites arises from their extraordinary features such as having …
Recently emerged perovskite materials show superior features like high efficiency, defect tolerance, facile synthesis, bandgap tunability and wide color gamut over their rivals in photonics applications. On the other hand, metals have interesting characteristics as they go small…
Many studies have focused on the insurance industry in the US and other developed countries. Few studies have investigated the efficiency and organizational form in developing countries. This is particularly true for the Takaful insurance industry. Takaful insurance is mutual in…
This thesis consists of two research problems in the air conditioning (A/C) area. For the first problem, the aim is to model and simulate a variable refrigerant flow (VRF) air conditioning system. The coefficient of performance (COP) for refrigeration or heat pump system is one …
Saudi stock market (SSM) has witnessed various market regulations and transformations taking place over the past decade. However, the impact of these reforms on market efficiency has not been addressed in the literature. Furthermore, idiosyncratic features of the market can play…
A high level of competition in the food industry, specifically in the Middle East and the UK has forced companies to improve their processes by reducing lead time, waste, and costs and increasing production efficiency. The main challenge to the achievement of the process improve…
This dissertation investigates the effects of alternative methodological approaches on estimates of farm efficiency. A meta-analysis is performed to examine the effects of factors such as functional form, sample size, type of product, number of variables in the model, and estima…
In the first essay, productive efficiency and some of the main factors affecting it in 11 countries in the Middle East and North Africa region were evaluated over the period 1980–99 using Färe's non-parametric approach. The results indicate that Oil producing countries are more …
James Clerk Maxwell's theories of electromagnetism are uniquely Victorian products. Maxwell and his physics have traditionally been viewed as aloof and disinterested, dating to the mid-to-late-19th century, but not party to the cultural, industrial, political, economic, and envi…
With the rapid development of battery technologies, battery energy storage systems (BESSs) have been allocated as great candidates for various types of ancillary service application in the power systems. On the other hand, many power systems around the world have opened their an…
Participation: the new tyranny?

Type: Book
In many countries around the world, in NGOs, private concerns and other organisations, participation is a buzz-word that fails to live up to expectations. These essays explore how participatory schemes fail and how to rectify the situation.
The 7 habits of highly effective people is recognised as one of the most influential books ever written. In this seminal work, Stephen R. Covey presents a holistic, integrated, principle-centred approach for solving personal and professional problems. With penetrating insights a…
Written by researchers from a wide variety of disciplines, this report explores the two most influential theoretical discourse traditions, namely Discourse Theory and Critical Discourse Analysis. Based on numerous Swedish and Scandinavian case studies, this account reveals the u…
The key unifying conceptual tool of this important entry in the study of efficiency and productivity is the directional distance function. In New Directions the authors take up this new performance measure while also maintaining their "traditional" axiomatic production theoretic…
