    Collective action involving public and private actors (e.g. public institutions, foreign and domestic investors) faces difficulties even in developed economies, let alone in economies that are still developing their institutions. Especially for the latter this lack of collective action in bringing public and private actors together in order to enhance policy making processes for viable and better policymaking performance is paramount. Oman is one such economy which, like many other economies endowed with natural resources, is trying to grow its non-hydrocarbon (non-oil-gas) sectors. Although there is a growing literature concerning the use of systems approaches in enhancing public and private sector governance there is a gap concerning the availability of such approaches in their simultaneous policymaking process; especially in developing economies and Oman in particular.Accordingly, the aim and objectives for this thesis were laid down to develop a methodological framework, based on a systems approach (viz. the viable system model-VSM) that could aid policymaking processes in Oman, respective institutional developments (ID), and ultimately growth in the non-hydrocarbon sectors. Developing in particular the kind of institutions required to foster collective action between the relevant public institution representatives (PIRs), foreign, and domestic investors.To investigate the above empirically 30 face-to-face interviews were held with foreign and domestic investors; whereas two focus groups were held with a 14 government institutional representatives. Their results are used to demonstrate the operation of the aforementioned methodological framework.This thesis is thus making an original and substantial contribution to the body of knowledge concerned with ID, collective public-private action, through the successful use of VSM. Filling thus the aforementioned gap identified in the literature, within the Omani context

    \ua9 2017 Intisar Al Alawi et al. Globally, end-stage kidney disease (ESKD) is a huge burden on health care systems. The aims of this study were to perform a comprehensive epidemiological and etiological report of ESKD patients commencing RRT in Oman with an emphasis on genetic causes and inherited kidney disease. All newly registered Omani patients with ESKD commencing RRT from 2001 until 2015 (n=2,922) were analysed using the RRT register in Oman. All potentially genetic or inherited causes of ESKD were reviewed. In Oman, ESKD is more prevalent in males (57.1%) than females (42.9%) with a median age of incident ESKD of 53 years. Diabetic nephropathy was the most prevalent cause of ESKD (46%), followed by hypertensive nephropathy (19%), glomerulonephritis (15%), and inherited kidney disease (5%). For patients less than 20 years of age inherited kidney disease accounted for 32.5% of cases. Of this cohort with inherited renal disease, 40.3% had autosomal dominant polycystic kidney disease, 11.5% had congenital anomalies of the kidney and urinary tract, 9.4% had Alport syndrome, and 7.2% had autosomal recessive polycystic kidney disease. This study represents a comprehensive population-based epidemiological and etiological report of ESKD patients in Oman commencing RRT. Inherited kidney disease was the leading cause of paediatric ESKD

    The current fast track urban growth is an important characteristic of the emerging city of Doha. Such a growth is marked by intensive infrastructure projects, high rise clusters of glass towers, new cultural facilities and art museums, emerging residential environments on the periphery of the city, as well as hall mark events. However, very few studies have addressed several important growth aspects, including the examination of the way in which the inhabitants comprehend and react to their built environment and the resulting spatial experience. This paper examines the inhabitants' spatial experience in key urban open spaces in the city by applying cognitive and behavioural mapping procedures coupled with an attitude survey. Applying the cognitive mapping technique, 108 responses were received, analysed, and classified under three categories a) living, working, and visiting patterns; b) comprehension of home range, home zone, and movement; and c) ethnic affiliation: Qataris and other Arab expatriates. Implementing direct systematic observation and behavioural mapping of key urban open spaces reveals important outcomes that include absence of physical aspects amenable for effective use while offering a pleasant experience for visitors. The findings contribute to an in-depth understanding of the inhabitants' spatial experience of the everyday urban environment of Doha. A conclusion is established to emphasise that by developing knowledge generated from research findings that are derived from the direct experience of inhabitants, the various aspects of how certain areas work within the urban structure of the city can be elucidated, while seeking means for improving the qualities of the everyday urban environment

    The amount of Arabic electronic information is growing drastically on the web. Statistics shows that the number of Internet users in the Middle East has increased enormously since the year 2000 due to increase in ICT awareness and its importance within Arab countries. As a result this has raised the need to find effective methods and techniques for allocating and retrieving the Arabic-based content from the web. This paper presents major Information Retrieval (IR) tools and techniques and it highlights few challenges in this regard

    Experiential assessment of urban open spaces in Doha

    Get PDF
    The current fast track urban development process is an important characteristic of the city of Doha. No exploration or examination of its urban spaces, however, has been done before. This paper offers an experiential assessment of three key urban open spaces by examining their spatial and physical characteristics while implementing direct systematic observation and behavioural mapping procedure. Assessment results reveal important outcomes that include absence of physical aspects amenable for effective use while offering a pleasant experience for visitors. The findings contribute to an in-depth understanding of the qualities of the three spaces and the resulting use, activities, and behaviour representative of the inhabitants' spatial experience in those spaces. While the overall experience of users appear to be satisfactory, the results convey that there is an absence of landscape features and a dearth of green spaces and appropriate outdoor furniture, absence of adequate shaded areas and shading devices and a lack of children's facilities or specially designated areas for children. Addressing the lack of features that enhance people's activities and use of these spaces would contribute to making the spaces more conducive for use by different types of users and at different days and times

    Despite the current fast track urban development process that characterizes the city of Doha, very few studies have addressed several important growth aspects, including the examination of the way in which its inhabitants comprehend and react to its built environment and the resulting spatial experience. This paper examines inhabitants' spatial experience in the city by applying cognitive mapping procedures coupled with an attitude survey. 108 responses were received, analyzed, and classified in three categories a) living, working, and visiting patterns; b) comprehension of home range, home zone, and movement; and c) ethnic affiliation: Qataris and other Arab expatriates. The findings contribute to an in-depth understanding of the inhabitants' spatial experience. The study concludes with an emphasis that by establishing knowledge generated from research findings that are derived from direct experience of inhabitants including movement patterns and the rhythm of geographical locations within the city, the various aspects of how certain areas work within the urban structure of the city can be elucidated

    Get PDF
    Traditional souqs in the Arabian Peninsula continue to be major focal points of trade, commerce, exchange, entertainment and social interaction. Souq Mutrah, in Muscat, Sultanate of Oman is one of these important regional souqs. This paper develops an experiential walkthrough assessment of three selected urban spaces - market places within Souq Mutrah by examining their spatial and socio-cultural aspects while implementing direct systematic observation and behavioral mapping procedure. The findings contribute to an in-depth understanding of the qualities of the three spaces and the resulting use, activities, and behavior representative of the inhabitants' spatial experience in those spaces. Assessment results reveal important outcomes that include that safety and security is the significant missing factor in Souq Mutrah spaces, which if provided, can attract more users while supporting their needs

    Enhanced aspect level opinion mining knowledge extraction and representation

    There is a need to find more effective techniques to extract, classify, represent and summarize customers’ online opinions on products and services for better sentiment analysis. The aim of this thesis is to enhance aspect level opinion extraction and representation. This study uses SentiWordNet lexical resource which is specifically built for opinion mining and widely used in sentiment analysis. This research introduces an approach using adjectives, verbs, adverbs and nouns (AVAN) which analyses all opinion word types for sentiment analysis and not only limited to adjectives and adverbs as have been conventionally done. SentiWordNet is used in this thesis to identify and analyze all word types for opinion extraction and representation. Opinion representation is enhanced by capturing key elements of opinions into predicates that consists of opinion word, strength, score and category in order to improve the opinion representation and classification. Then it further enhances the mining by introducing opinion accounting which summarizes opinion scores at various group levels. In addition, this thesis introduces a new concept called opinion strength which classifies opinions into degrees. An enhanced score is assigned to opinion based on the strength at which these opinions are expressed. Furthermore, as opinions are fuzzy in nature, this study shows that fuzzy logic is an effective technique to address opinion vagueness since human-like logic is fuzzy. This is important as opinions should not only be categorized in classical Boolean sentiments. This study identifies SentiWordNet, AVAN, Opinion Strength and fuzzy logic as classification features to classify customer reviews into a 5-class prediction model (Excellent, Good, Fair, Poor and Very Poor ). The results show an accuracy of 92% using Sequential Minimal Optimization classifier for these features, outperforming previous works that implemented Support Vector Machine and Logistic Regression. Moreover, combination of AVAN, Opinion Strength and fuzzy logic outperformed SentiWordNet alone by a 30% accuracy
