The impact of privatization on management control systems in less developed countries : comparative case study from EgyptDerbala, Ahmed Khairy mohamed January 2014 (has links)
The current research is motivated by the controversy between the proponents and opponents of privatizing SOEs in LDCs concerning its impact on the MCSs designed and implemented in these companies. On the one hand, proponents expect privatization to foster the design and implementation of market-based, consensual and transparent MCSs. On the other hand, opponents are more critical about the ‘actual’ changes that privatization might entail to SOEs’ MCSs as they expect it to entail the design and implementation of non-transparent, coercive MCSs. When examined closely, this conflict was found to be rooted in the different theoretical perspectives adopted by each side. While proponents base their arguments, mostly, on ‘traditional’ agency and property-rights theories that underplay the role of structure in shaping the MCSs designed and implemented in privatized companies, many of the opponents base their arguments on neo-Marxist theories that underplay the role of agency in that process (namely labour process theory- LPT). The current research contributes to this debate through developing a power-informed theoretical model that acknowledges the role of both agency and structure in shaping the nature of the pre- and post-privatization MCSs designed and implemented in companies operating in LDCs. The model provides an attempt to develop the Hopper et al (2009) model through integrating into it a theory of power informed by the works of Lukes (1974 and 2005) and Gaventa (1980 and 2007) while adopting the integrative agency-structure approach suggested by Mahoney and Snyder (1999).Once developed, the model is used to guide the analysis of the relevant literature pertaining to Egypt’s supra-national and national power relations and structural factors throughout its state and market capitalism eras as a first step towards comparatively analysing the pre- and post-privatization power relations and MCSs manifesting in two Egyptian companies. The empirical data was mainly collected through conducting semi-structured interviews in the two companies and with some of the government officials involved in their privatization. Other sources of data include the companies’ internal records and financial reports, government publications, and newspapers. The comparative analysis shows how the power-informed model can help shed more light onto the nature of, and the dynamics of change in, MCSs transformations in LDCs; without having to abandon LPT as one of the main theoretical perspectives informing the analysis. While doing so, the nature of a company’s MCSs (be it coercive, consensual, or irrelevant) is found to reflect the power relations manifesting in that company (namely, powerful management, comparatively powerful management and labour, or powerful labour, respectively). Furthermore, as the comparative analysis shows, it is found that privatization is more likely to result in changing the nature of a SOE’s MCSs when it entails altering the power relations shaping these MCSs.

Evaluation of replacing fixed with controllable line reactors in mature power systems overlaid with higher voltage linesNojozi, Hactor Ma-Ande 27 May 2013 (has links)
M.Ing. (Electrical and Electronic Engineering) / Shunt reactors are used in power system amongst other things, to suppress overvoltages in the network during network switching, auto reclosing of transmission lines and under low loading condition of the network. Traditionally, shunt reactors of fixed type have been used and these have been permanently connected to the system. This research work investigated the feasibility of replacing the fixed shunt line reactors with a reactor, whose parameters are automatically varied depending on the system reactive power requirements, in a mature power system overlaid with high voltage lines to improve amongst, other things voltage stability. However, in a mature system overlaid with parallel higher voltage lines, power tend to flow on the matured system rather than higher voltage system as predetermined by various impedances of the power system. It is therefore desirable that loading of higher voltage lines be increased because of their higher power transfer capability and fact that higher voltage networks generate capacitive power which is substantially more than for each line at the original voltage. However, replacing a large number of fixed line reactors, at low loadings of higher voltage lines, even when system collapse is averted by increasing the number of reactors inserted into the system, overvoltage problems may still be an issue, until a certain number of must-run reactors, operating at full reactance, are put into service. If too much inductive reactance is removed from the system when the loading levels are extremely low, the power system will collapse. Therefore, there was no economic benefit in replacing all the fixed shunt line reactors with controllable type when the loading was still relatively low. Thus, the majority of the converted reactors were operating in their full rating as there was still more reactive power to be absorbed. However, when the power was diverted to flow on the higher voltage system through the use of series compensation of the higher voltage system, there was a possibility of making some fixed shunt line reactors on the higher voltage network controllable. This also allowed more power to be transferred in the higher voltage system thus improving its utilisation. Also, a positive impact on active system losses was realised.

Application of catastrophe theory to transient stability analysis of multimachine power systemsParsi-Feraidoonian, Raiomand January 1990 (has links)
Transient stability analysis is an important part of power planning and operation. For large power systems, such analysis is very time consuming and expensive. Therefore, an online
transient stability assessment will be required as these large power systems are operated close to their maximum limits. In this thesis swallowtail catastrophe is used to determine the transient stability regions. The bifurcation set represents the transient stability region in terms of power system transient parameters bounded by the transient stability limits. The system modelling is generalized in such, that the analysis could handle either one or any number of critical machines. This generalized model is then tested on a three-machine as well as a seven-machine system. The results of the stability analysis done with the generalized method is compared with the time solution and the results were satisfactory. The transient stability regions determined are valid for any changes in loading conditions and fault location. This method is a good candidate for on-line assessment of transient stability of power systems. / Applied Science, Faculty of / Electrical and Computer Engineering, Department of / Graduate

Domestic Violence, A study of men's violence in close relationshipChristensen, Katherine Batenga January 2018 (has links)
The Aim of this study is to examine violence in close relationship and to explore the different explanation on men's violence as well as the factors that contribute to their violent behavior. Violence in close relationships can occur in different forms and anyone can fall as a victim of both physical and mental abuse. Violence and discrimination against women violates the principles of equal rights and respect for human dignity. In Sweden, men's violence against women and violence in close relationships is still a major problem that requires great work and attention. It is one of Sweden's responsibility to meet all people's equal values and rights and to fight violence in close relationship.
