Although several multi-dimensional models of strategic decision-making processes (SDMPs) have been examined in the literature, these studies have paid insufficient attention to the public sector context and Gulf Cooperation Council (GCC) region. SDMP in the public sector and the State of Qatar can vary to SDMP in the private sector due to institutional and socio-cultural differences respectively. Therefore, more research is urgently needed to better understand SDPM within this context. To contribute to filling this void, this study develops and tests a multi-dimensional SDMP model including SDMP dimensions, implementation, and outcome. The study model examines (𝑖) the impact of four SDMP dimensions—procedural rationality, intuition, constructive politics, and participation—on the implementation success of the strategic decision; (𝑖𝑖) the impact of the successful implementation of SD over the SD quality; (𝑖𝑖𝑖) the mediation role of the implementation success of SD; (𝑖𝑣) the moderation effect of stakeholder uncertainty. The model was analysed using Partial Least Square Structural Equation Modelling (PLS-SEM) and tested using data from multiple informants on 170 strategic decisions in 38 Qatari public organisations. The study finds that procedural rationality, constructive politics, participations, and the implementation Success of SD plays a significant and positive role on SDMP and its overall outcome. Finally, the study provides substantial and original contributions to the knowledge of SDMP in the public sector; implications for decision-makers and directions for future research.

Thesis (MEng)--Stellenbosch University, 2014. / Construction projects have developed over several decades through the advancement of technology, increased scarcity of resources and the ever increasing pressure of time and cost constraints. Because of new technology and modern construction methods, construction projects have become increasingly complex. These complexities inherently bring new risks that must be dealt with accordingly. A contract is the primary method through which risks are allocated between the Employer and the Contractor. The conditions allocating the risks legally bind both parties to accept responsibility of those risks, therefore it is important to understand the aspects of law that has bearing on contracts. In this thesis the scope is restricted to construction contracts. Because of the role that a contract plays, especially in the construction industry context, it is important to know the requirements of a modern contract to ensure the successful completion of projects and the continued sustainability of Employer-Contractor relationships. In South Africa, the Construction Industry Development Board (CIDB) is a body that monitors developments in the construction industry. The CIDB has the authority to enforce legislation to ensure that contracts conform to a standard that protects the interests of both the Employer and the Contractor. One of the procurement documents endorsed by the CIDB is the General Conditions of Contract for Construction Works published by the South African Institution of Civil Engineering (SAICE). The first edition of the GCC was published in 2004 (GCC 2004) and a revised second edition was published in 2010 (GCC 2010). In this study the GCC 2010 and the GCC 2004 are compared first through a content analysis, to establish the effect the revisions on the bias of the document (or favouring a particular party) and then by means of a survey. The objectives are: a. To test whether revisions to the GCC from the 2004 edition to the 2010 edition resulted in a change in bias (assuming it exists) and compliance with the requirements of the modern contract; b. To determine the extent and effect of alterations to standard clauses of the GCC 2010 on the way in which the contract favours a particular party; c. Providing recommendations for future revisions that would potentially improve project success, relationship building and reduce the need for significant alterations to the standard clauses. Although a construction contract is undertaken between the Employer and the Contractor, the Consultant (who is not party to the contract) commonly drafts the contract on behalf of the Employer. The findings of the study show that the revision had a significant impact on improving the clarity of the roles of the Employer and the Contractor. A marginal improvement was found in the area of payment operating mechanisms. The perceived fairness of the document neither increased nor decreased. Clauses on claims and disputes and risk and related matters were the two areas that respondents identified as having the most bias that may be detrimental to the success of a construction project. Despite survey respondents finding the GCC 2010 procurement document to be fair, clauses are still altered by Employers (probably through Consultants) resulting in a biased contract favouring the Employer. Employers and Consultants should thus be educated more on bias and fairness in contracts and on the implications of shifting more risk to Contractors by altering clauses. Ultimately, the success of any construction project is dependent on the attitudes of the participants. Even the most fair procurement document is not a substitute for a relationship built on honesty and trust.

The global water crisis has often been presented as a crisis of governance and attributed to various factors, including the slowness of institutional adjustments to rapid structural challenges such as demographic growth, resource degradation and economic difficulties (UNU-INWEH, 2012). Despite the rapid growth of cities around the world and a fast increase in the use of desalination for freshwater supply (WHO, 2011), the dynamics of institutional change in desalinated urban water governance have never been researched. This thesis investigates the drivers, barriers and counter-forces to a major institutional change - privatisation - in the desalinated water governance of the coastal cities of the Gulf Cooperation Council (GCC) region. Through the cases of public private partnerships (PPPs) in Abu Dhabi and Doha and the failed attempt to implement similar PPPs in Kuwait City, this research investigates the diverse forces that have led to the implementation of this new institutional arrangement in order to question - both empirically and theoretically - the literature’s general assumption that privatisation reforms in urban water services in the South arise from structural issues, e.g. a water crisis, an economic crisis and/or a governance crisis. The three main schools of comparative studies are used systematically to test hypotheses about causal relationships between selected variables. The structural approach is applied to examine the influences of the redistributive rentier state, oil price fluctuations and regional energy integration over the privatisation process. Adopting a Post-colonial perspective, the political culture approach is used to examine critically the contemporary influences of traditional cultural features, key local institutions and foreign cultural influences over the fluctuating roles of both the State and the markets in the local urban water supply since the late 19^th century. Finally, the rational agency theory is used to examine the role in the recent privatisation process of key political figures from the ruling families. This research demonstrates that the privatisation process of desalination units in Abu Dhabi and Doha was not driven by structural factors during the 2000s, a period of high oil prices, but was initiated in the 1990s and driven the following decade by the agency of a reforming elite wanting to privatize the water sector as part of a broader dynamic of construction of a neoliberal post-rentier economy – i.e. an intermediary political economic paradigm that aims to mediate the transition from rentierism to a fully liberalized economy. The political culture approach shows that these privatisations were facilitated by a gradual shift from pure rentierism towards a post-rentier form of neoliberalism in the political philosophy of liberal water technocrats on the one hand, and towards a regional trend of ‘pious neoliberalism’ (Atia, 2011) among practicing Sunni Muslims. Nevertheless, the enduring rentier mentality has constituted a strong counter-force to privatisation dynamics. The PPPs were implemented in Abu Dhabi and Doha because the local ruling elites situated the political bargaining within the tribal institutional milieus that they mastered completely through the control of the rent and related benefits. In Kuwait however, negotiations between the ruling elites and the leading political forces, the tribes and the opposition, were situated in a parliamentary institutional milieu that the ruling elite could not control and where the opposition and tribal MPs have opposed all reforms of the rentier ruling bargain. These findings illustrate that institutional changes in desalinated water governance are not neutrally driven by uncontrollable structural forces, but are the product of political bargaining between and among various rational political actors and their coalitions. This thesis also shows that in non-democratic or semi-democratic settings, the choice of a specific institutional milieu by the authorities is critical to the successful bargaining of institutional reforms, since it determines whether some key actors - along with structural factors (e.g. rent) and cultural factors (e.g. tribal influence) - will support the process or will be able to act against it.

In today's increasingly competitive business environment, the use of knowledge to gain a competitive advantage has become a serious concern for all organisations. However, some industries have been affected more acutely than others in the transition to a knowledge-based economy. Despite the increasing number of studies relating to Knowledge Management (KM), few have explored this concept within the Airline Industry (AI). As all the studies and model of this research have built on the relationship between KM and organisational performance (OP), the AI is the context of the study within the area of Gulf Cooperative Countries (GCC). This area has been chosen as it provides a good airlines-based industry which is mature. A comprehensive and critical assessment of different KM models was made through a review of the available studies in order to evaluate KM and to identify the processes that affect OP. This research proposes a conceptual model that represents KM processes and OP measurements. This research adopts a qualitative research approach through a case study strategy to identify and test a conceptual model proposed from the literature review. Four international airlines companies were investigated through extensive face-to-face semi-structure interviews, followed by observations, and documentation with managers, senior managers, general managers (GMs) and vice presidents (VPs) to produce accurate results. Data findings were then reported and analysed. The main finding revealed that most studies relating to knowledge management processes and their effect on organisational performance took place in different sectors other than the AI. Also, KM processes and their effect on OP appear to be neglected, leading to conflicts in KM adoption. However, KM processes are applicable in the AI and these processes are not only used and implemented, but are also perceived as important in influencing positive OP. The only KM processes that generally received less support from the participants in terms of perceived effectiveness in affecting positive OP were knowledge translation/repurposing and knowledge disposal. The main contribution of this research is a novel model for KM processes and OP. This model serves as a guideline for the stakeholder and decision maker to be adopted in organisations to lead to more effective implementation and adoption of KM disciplines. It also provides a practical guideline for future KM research which at present seems fragmented within the AI. The suggestion for future research is to further validate and improve the generalisability of the KM processes model to the entire AI in the world and across other industries. Moreover, due to the time constraints and lack of funding, there were no attempts made in this research to assemble a sample that is representative of all the airlines in the world. In order to increase the generalisability of the results of this study, the sample size needs to be expanded and quantitative research might be considered.

The Convention on the Elimination of All Forms of Discrimination against Women (CEDAW) which was adopted in 1979, and the 1995 Beijing Declaration and Platform for Action have generated global and regional momentum in the advance of equal gender opportunities. This research explores the increased presence of women in higher education and their subsequent entry into the workforce in the United Arab Emirates. The government has attempted to reduce its citizens' dependency on public sector employment and promote opportunities in the private sector. Governmental efforts have included improving the education system, granting women access to education and introducing funding schemes to encourage employment initiatives. Yet, despite these efforts, unemployment across the UAE remains at a high level, with public sector favoured by Emirati nationals. The country's drive to nationalise the labour force reflects the necessity of utilising the capabilities of Emirati nationals, both men and women, to diversify the rentier state economy. Emiratisation is a national government strategy in the United Arab Emirates that aims to reduce the country's reliance on expatriate labour and increase the participation of nationals in the labour market, both in the public and private sectors. The research for this thesis begins by exploring the inadequacy of classical rentier state theory and examining Mathew Gray's theory of late rentierism within the context of the United Arab Emirates. It further builds on the late rentierism model with a particular focus on the role of women, education and youth participation. The methodological approach used in this research is primarily qualitative, including interviews with final year university students, and professionals in the banking sector of both sexes. These groups were chosen to highlight the practical implications of governmental Emiratisation policies aiming to increase job opportunities across the United Arab Emirates. To date, very little research has been conducted on the issues of gender, work life balance policies and new workforce trends in the UAE.
