The dissertation thesis is focused on value based systems of remuneration. Importance and mission of remuneration systems at company management leading to increase in value for owners, respectively for stakeholders is investigated here. The dissertation thesis deals with the factors influencing both, employees, their performance and motivation for company´s aims achievement, and companies´ systems of remuneration. The subject of dissertation thesis is actually concurrent because employees´ performance increasing in a form of stimulation bonuses, an effort for possessing employees in the company, and dividing company´s profit for employees at the same time are very demanding managerial tasks in every stage of company´s development. At the dissertation thesis elaboration, the author has stemmed from theoretical backgrounds of scientific publications of Czech authors as well as of foreign authors, and also from realized investigations. Primary research has been realized by a combination of single techniques of quantitative research, i.e. by the means of questionnaires, personal interviews and telephonic interviews. Results of the primary research obtained have been analysed using the applications of Microsoft Excel, Portable Open Office Calc and XLStatistics software. Results obtained at elaboration of the dissertation thesis have been used with the aim to determinations of the most important factors influencing employees´ motivation for performance increasing and interestedness on company´s goals achievement. Moreover, the results obtained by primary research outcomes analysis have made possible the statistic verification of the hypotheses of dissertation. The partial outcome of dissertation thesis is the definition of premises of value oriented systems of remuneration use in small and medium-sized entities. Based on this definition of these systems implementation premises, the methodical order of implementation of value oriented system of remuneration into company´s practice. For elaboration of the value oriented system of remuneration proposal, first of all, it has been necessary to create the system of EVA quantification in a company, i.e. to divide company´s assets into responsibility centres, to calculate EVA of every single responsibility centre, and to propose a concept of employees´ interest on change of the EVA indicator value. The proposed methodology has been proved in condition of concrete company, and in the dissertation thesis, it is presented as a case study. This way, one can get complete information about characteristics of the presented model, in concrete about necessary adjustments of costs and revenues, about determination of the amount of invested capital and its valuation, and about division of created value for employees and owners as well. Elaborated case study provides a feedback on a possibility and demandingness of implementation of value based systems of remuneration in small and medium-sized entities. The conclusion of dissertation thesis is devoted to the summary of knowledge obtained, to the discussion of premises for the proposed methodology implementation into business practice, and to the discussion about possibilities of next scientific work in elaborated area.

Mettaoui, Mirjam Lanjri. "Remuneration in the Corporate Governance Systems from International Perspective." Doctoral thesis, Vysoká škola ekonomická v Praze, 2010. http://www.nusl.cz/ntk/nusl-161860.
Full textAbstract:
The following work is a contribution to the research in the field of remuneration and corporate governance. Main aim is to get answers on the question on the relationship between the disclosure of the remuneration system and the firm value. The first research question is, if there is a positive effect of the disclosure of remuneration information on the firm value. Second important research questions are how many companies have separate published remuneration reports and what the qualitative level of the remuneration reports is. The first part of the work gives a literature review of the State-of-the-Art-literature of Corporate Governance and Remuneration. The work includes an Empirical Study of a sample of 100 companies and the existence of separately on the companies' websites published remuneration reports. The contents and the structure of the reports are compared via an indicator-list. Main identified aspects are the remuneration approach, the concept of the report and the disclosure of remuneration. The Event Study method is used to test the relationship between the disclosure of the remuneration system and the firm value. The method is chosen to have the possibility to isolate the factor remuneration system from other influencing factors. Share price and target return, S&P 500 index and target return, abnormal return, standard deviation and differences are computed. The results are compared and indicate that there is a positive effect, because the firm value of the chosen companies are higher after the event than before the event, although the results are not statistically verified. A positive effect on the firm value would be an incentive for companies to publish the information of remuneration in future.

Full textAbstract:
Performance measurement and management (PMM) poses daunting challenges to organizations in terms of meeting multiple stakeholder objectives. Evaluation of these objectives, and hence performance is essential for many reasons such as monitoring and control, diagnosis, improvement, learning and decision-making of processes or enterprise systems. Performance measures as descriptors of performance are the key tools in this evaluation process. However, the multidimensionality of performance, the inter-dependencies among performance measures and the pursuit to manage many dimensions of performance complicate the PMM process. Furthermore, the uncertainty in terms of objectives satisfaction surrounding the business processes or enterprise systems adds further complexity. To deal with these issues, a process-centered value-risk based performance management system (VR-PMS) is proposed in the current research work. The purpose is to transform the expectations and fears of stakeholders into value and risk indicators respectively for informed decision making. For this purpose, a conceptual value-risk model is developed aimed at integrating consistently the concepts relevant to objectives, activities and risks in one framework and conceptualizing the idea of value and risk based performance management. In addition, a methodological framework is developed that divides the PMM process into three phases: performance modeling, assessment and decision-making. Each phase of the framework is instrumented with quantitative analysis methods and tools. The deliverable of the VR-PMS is a set of ranked solutions (i. E. Alternative business processes) evaluated against the developed value and risk indicatorsLa mesure et la gestion de la performance posent problème aux entreprises en termes d'atteinte des objectifs des multi parties prenantes. L'évaluation de ces objectifs et ainsi de la performance est essentielle pour plusieurs raisons : le contrôle et la surveillance, le diagnostic, l'amélioration, l'apprentissage et la prise de la décision de processus ou système d'entreprise. Les mesures de performance étant les descripteurs de la performance jouent un rôle important dans cette évaluation. Cependant, la multi-dimensionnalité de la mesure de performance, l'interdépendance entre elles et la recherche pour mesurer plusieurs dimensions de la performance compliquent le processus de mesure de performance. De plus, l'incertitude en ce qui concerne l'atteinte des objectifs atours du processus métiers ou système d'entreprise y ajoute encore de la complexité. Pour aborder cette situation, un système de mesure de performance basé sur l'indicateur du couple (valeur-risque) (appelé VR-PMS) orienté processus a été proposé. L'objectif est de transformer les atteintes et inquiétude des parties prenantes en un indicateur de la performance et un de risque respectivement pour prendre une décision en connaissance de cause. A cet effet, un modèle conceptuel de valeur/risque est proposé : il vise à intégrer les concepts associé aux objectifs, activités et risque dans un seul cadre et conceptualise l'idée de la gestion de performance basée sur la valeur et risque. En outre, un modèle méthodologique est élaboré et divise les processus de mesure de performance en trois étapes : la modélisation de performance, évaluation et prise de décision. Chaque phase du modèle est dotée d'outils et méthodes pour l'analyse quantitative. Le livrable de VR-PMS est un classement de solutions (c'est-à-dire alternatives de processus métier) évaluée vis-à-vis l'indicateur développé à partir de valeur et risque

Currently, program-funding allocation is based on program performance. Funding cuts commonly lead to a poor reflection on the program management assigned to the given program. If additional factors such as program risk and benefit are objectively factored in, this may lead to a more effective exit strategy for program capabilities, which are no longer required. An enterprise architecture analysis and applied framework case study were carried out to develop a methodology to quantify system-level value for the Office of the Assistant Secretary of the Air Force for Acquisition Research, Development, Test and Evaluation portfolio. Portfolio value is quantified in order to transition from a single program, single stakeholder value analysis to a program portfolio and stakeholder system composite analysis. This methodology is developed based on interviews, official organization literature, and a case study. The results of the applied framework case study on a portfolio of seven programs showed a positive correlation between quantitative capability, execution and risk data at the portfolio level and access to a more informed and objective identification of programs of greatest interest and concern as compared to a qualitative program-by-program analysis when allocating Air Force Acquisition resources. This system includes 17 stakeholder categories, which significantly influence the allocation of resources for a portfolio worth roughly 0.4% of the US GDP. Interviews include high-ranking leadership, including two 3-Star Generals in the US Air Force.

Full textAbstract:
Thesis (MPhil)--University of Stellenbosch, 2003.ENGLISH ABSTRACT: The historical development of the role of directors in public listed companies contains inherent tensions by reference to the fiduciary responsibility of directors and the method in which directors are remunerated. The nature of incentive based remuneration is such that it will compel directors, in certain circumstances, to weigh their interests against those towards whom they owe a duty of care and a moral responsibility to act with prudence and temperance. The modem day corporate environment is complex and calls for directors with strong ethical views. This assignment endeavours to identify some of the complexities that contribute towards directors finding it difficult to stay on the ethical "straight and narrow" and attempts to weigh the effect of those factors against the effect of incentive remuneration, both as detractors from ethical behaviour. Both the shareholder supremacy business model and the stakeholder approach are analysed to identify those factors present in each that may add to the ethical complexity that directors have to deal with. The advent of the stakeholder approach in particular, adds an enormous amount of complexity. The case studies deal with two South African financial services companies that have both ceased trading as a consequence of unethical behaviour. The incentive remuneration models of both companies have been found to have played a major contributing role in the decision making processes in the companies, and have contributed to the demise of these organisations. Lessons are taken from the case studies and applied against the backdrop of the various principles of ethical behaviour namely rights, utility, justice and the ethics of responsibility. The finding of this study is that there is a role for incentive remuneration of directors, provided that the ethical pitfalls that this causes are recognised and steps taken to address them. Some of these steps are identified.
AFRIKAANSE OPSOMMING: Die historiese ontwikkeling van die direkteursrol, en spesifiek van openbare genoteerde maatskappye bevat inherente teenstrydighede met verwysmg na direkteursvergoeding en die vertrouensverpligtinge wat op direkteure rus. Die aard van direkteursvergoeding met 'n aansporingskomponent is so dat dit 'n direkteur van tyd tot tyd in 'n posisie plaas waar hy tussen sy eie belange en die van die ander belanghebbendes in 'n maatskappy, aan wie hy dit verskuldig is om met verdrag en versigtig op te tree, moet kies. Die hedendaagse maatskappyomgewing is kompleks van aard, en vereis direkteure met sterk etiese oortuigings. Hierdie werkstuk poog om sommige van die komplekse faktore wat afbreuk doen aan 'n direkteur se vermoe om ten alle tye streng eties op te tree, te identifiseer en op te weeg teen die effek wat direkteursvergoeding speel - beide as items wat afbreuk doen aan etiese optrede. Hier word ondersoek ingestel na beide die sogenaamde "aandeelhouersmodel" asook die" belanghebbende" model waarvolgens besigheid bedryf word. Die ontsluimering van die belanghebbende model veroorsaak spesifiek 'n aansienlike hoeveelheid etiese kompleksiteit. Die gevallestudies behandel twee Suid Afrikaanse fmansiele instellings wat hul bedrywighede gestaak het as gevolg van onetiese optrede deur direkteure. Die aansporingskomponent van die vergoedingsrnodelle in daardie maatskappye blyk 'n groot bydraende faktor te wees in die onetiese besluitneming wat plaasgevind het, en wat uiteindelik tot die ondergang van die ondernemings gelei het. Laastens, word die lesse wat geleer is uit die gevallestudies, toegepas in gewysigde format, en getoets aan die hand van die verskillende beginsels wat etiese besluitneming onderhou, naamlik die beginsels van regte, regverdigheid, utiliteit en die beginsel van etiese verantwoordelikheid. Daar word tot die slotsom gekom dat daar wel ruimte vir aansporingskemas vir direkteure is, maar dat dit slegs eties regverdigbaar sal wees mits ag geslaan word op die lesse wat uit die gevallestudie voortspruit, tesame met die impementering van sekere korrektiewe maatstawwe.

Full textAbstract:
This research argues that the information security governance objectives should be grounded in the values of organizational members. Research literature in decision sciences suggest that individual values play an important role in developing decision objectives. Information security governance objectives, based on values of the stakeholders, are essential for a comprehensive security control program. The study uses Value Theory as a theoretical basis and value focused thinking as a methodology to develop 23 objectives for information security governance. A case study was conducted to reexamine and interpret the significance of the proposed objectives in an organizational context. The results suggest three emergent dimensions of information security governance for effective control structure in organizations: resource allocation, user involvement and process integrity. The synthesis of data suggests eight principles of information security governance which guides organizations in achieving a comprehensive security environment. We also present a means-end model of ISG which proposes the interrelationships of the developed objectives. Contributions are noted and future research directions suggested.

The Personal Router is a mobile communication device developed by the Advanced Network Architecture group at the MIT Laboratory for Computer Science. The Personal Router is able to select and negotiate connectivity with local providers for different kinds of services and interfaces. It needs payment procedures to support these services. As this device is designed to be used in many distinct unpredictable contexts, it cannot implement a single payment system. The complexity of existing payment systems has to be mapped into this new environment. A different payment system must be chosen each time, depending on many variables such as costs, environmental constraints, privacy, user and provider's needs and preferences. Privacy is a major issue for this device. In effect, getting wireless and mobile service everywhere will possibly leave an easily traceable trail; moreover, using this device supposes negotiating with many different untrusted providers and paying for the service. This can create huge potential threats for privacy and personal data management if this issue is not included in the early stage of the design. Legal requirements and user preferences and expectations for privacy in electronic transactions are therefore explored. Past attempts to enhance privacy in different environments are examined. Reasons why most of them have failed and some of them are struggling to stay alive are analyzed. New privacy threats faced by the Personal Router are considered. A new approach based on building blocks is made. Payment systems are split into primitive operations; each of them implements one step of a transaction. The combination of these building blocks replicates a payment protocol. The characteristics of a payment system can then be derived from the analysis of the implementation of each of these primitives. Users' preferences are defined by attributes. Payment systems can then be compared through their primitives and even slightly modified to be closer to users' ideal system by altering the primitives. The modular approach makes this easier. This framework is successfully tested on three major electronic payment systems. Several limitations of this approach and open issues related to the Personal Router are exposed.

The Earth Science and Applications decadal survey released by the National Research Council in 2007 presents both an ambitious engineering challenge and a challenge for the entire Earth science community to come together to reach a consensus on priorities that cross conventional disciplinary boundaries. The vision established by the decadal survey requires a paradigm shift for Earth system science: Societal benefits must be considered equally with purely scientific benefits to guide the development of the future NASA and NOAA Earth Observations Program. The decadal survey focused heavily on the needs and objectives of the Earth science community, while providing much less thorough treatment of the other relevant stakeholders. To address this, I conducted a stakeholder value network analysis for the Earth Observations Program that includes the development of a comprehensive qualitative and quantitative stakeholder model. The qualitative model includes a rigorous articulation of the needs and objectives of 13 major stakeholders; the development of a three-level stakeholder map including a baseline map, higher-level map, and lower-level map; and a complete stakeholder value network model with 190 individual value flows that capture the interactions between all the stakeholders. The quantitative model includes a method for assigning numeric scores to each value flow; the calculation of 1880 unique and valid "value loops" within the stakeholder value network; and an analysis of the value loops that yields useful insights about the Earth Observations Program. The value loop analysis reveals the most important stakeholders, value flows, and value loops within the stakeholder value network; as well as the most important outputs from and inputs to NASA and NOAA. The analysis also reveals the relative important of each of the six science categories representing the six science-themed panels of the decadal survey. The results from the stakeholder value network analysis provide insights regarding the value produced by the Earth Observations Program, as well as the value-added roles of each stakeholder within the network. The most important value loops and Program outputs are used to derive a set of high-level program goals, including goals that suggest what NASA and NOAA should do, as well as how they should conduct business. Finally, the insights and results from the analysis provide the foundation for a set of recommendations for the Earth Observations Program, which complement the recommendations put forth in the decadal survey.

Full textAbstract:
With extensive use of information systems in day-to-day business operations, many organizations are facing challenges to develop robust computer-based information systems that are secure and widely used by the user community. In order to develop information systems that are secure and useful, understanding what stakeholders consider important and value about the security and usability is critical. Security refers to confidentiality, integrity and availability and usability refers to efficiency, effectiveness and user satisfaction. Using Value Focused Thinking approach, this research first proposes the usability objectives based on the values of system developers and users. Using the security objectives proposed by Dhillon & Torkzadeh (2006) and the usability objectives, this research proposes hierarchies with the overall/over-arching goals of security (confidentiality, integrity, availability) and/or usability (efficiency, effectiveness and satisfaction). This research also analyzes a case of computer hacking and identifies which of the security and usability objectives that have not been met in that case study. The research contributions which include the usability objectives and security and usability hierarchies can be useful for theoretical as well as practical purposes.

Full textAbstract:
Data analysis has become a very important area for both companies and researchers as a consequence of the technological developments in recent years. Companies are trying to increase their profit by analyzing the existing data about their customers and making decisions for the future according to the results of these analyses. Parallel to the need of companies, researchers are investigating different methodologies to analyze data more accurately with high performance.
Recommender systems are one of the most popular and widespread data analysis tools. A recommender system applies knowledge discovery techniques to the existing data and makes personalized product recommendations during live customer interaction. However, the huge growth of customers and products especially on the internet, poses some challenges for recommender systems, producing high quality recommendations and performing millions of recommendations per second.
In order to improve the performance of recommender systems, researchers have proposed many different methods. Singular Value Decomposition (SVD) technique based on dimension reduction is one of these methods which produces high quality recommendations, but has to undergo very expensive matrix calculations. In this thesis, we propose and experimentally validate some contributions to SVD technique which are based on the user and the item categorization. Besides, we adopt tags to classical 2D (User-Item) SVD technique and report the results of experiments. Results are promising to make more accurate and scalable recommender systems.

Today's large-scale, high-performance, data-intensive applications put a tremendous stress on data centers to store, index, and retrieve large amounts of data. Exemplified by technologies such as social media, photo and video sharing, and e-commerce, the rise of the real-time web demands data stores support minimal latencies, always-on availability and ever-growing capacity. These requirements have fostered the development of a large number of high-performance storage systems, arguably the most important of which are Key-Value (KV) stores. An emerging trend for achieving low latency and high throughput in this space is a solution, which utilizes both DRAM and flash by storing an efficient index for the data in memory and minimizing accesses to flash, where both keys and values are stored. Many proposals have examined how to improve KV store performance in this area. However, these systems have shortcomings, including expensive sorting and excessive read and write amplification, which is detrimental to the life of the flash.
Another trend in recent years equips large scale deployments with energy-efficient, high performance co-processors, such as Graphics Processing Units (GPUs). Recent work has explored using GPUs to accelerate compute-intensive I/O workloads, including RAID parity generation, encryption, and compression. While this research has proven the viability of GPUs to accelerate these workloads, we argue that there are significant benefits to be had by developing methods and data structures for deep integration of GPUs inside the storage stack, in order to achieve better performance, scalability, and reliability.
In this dissertation, we propose comprehensive frameworks that leverage emerging technologies, such as GPUs and flash-based SSDs, to accelerate modern storage systems. For our accelerator-based solution, we focus on developing a system that features deep integration of the GPU in a distributed parallel file system. We utilize a framework that builds on the resources available in the file system and coordinates the workload in such a way that minimizes data movement across the PCIe bus, while exposing data parallelism to maximize the potential for acceleration on the GPU. Our research aims to improve the overall reliability of a PFS by developing a distributed per-file parity generation that provides end-to-end data integrity and unprecedented flexibility. Finally, we design a high-performance KV store utilizing a novel data structure tailored to specific flash requirements; it arranges data on flash in such a way as to minimize write amplification, which is detrimental to the flash cells. The system delivers outstanding read amplification through the use of a trie index and false positive filter.Ph. D.

Thesis (PhD)--University of Stellenbosch, 2003.ENGLISH ABSTRACT: The introduction of Outcomes Based Education in the South African school system brought about a new approach to education. The existing system of a multitude of subjects was replaced by a curriculum with eight learning areas. In this curriculum the focus is on attitudes, skills and values which replaced a content based approach with a process-based approach. Educators thereby became facilitators in the educational process. With the barriers of segregation removed in the South African society the diversity of the population created multi-cultural classrooms. Schools became the meeting place of many cultures and belief systems. Educators who facilitated learning in schools were not always prepared for the task of managing a multi-cultural and multi-religious school environment. This change within the school system required that educators make a paradigm shift regarding their role as educators. The introduction of Curriculum 2005 (1997); The Revised National Curriculum (2001) and the National Curriculum Statement (2002) was not without problems in South Africa. Many educators resisted change and had negative perceptions about the implementation of Outcomes Based Education in schools. These perceptions stemmed from inadequate training of educators for the implementation phase of the curriculum. The lack of skills to facilitate the content of the curriculum was also visible in the educators' inability to identify values in the curriculum. The multi-cultural and multi-religious classroom confronted educators with values from the different value and belief systems of learners. It is, therefore, important that educators should be able to identify values in order to attain the outcomes of the curriculum. Previous research indicated that educators did not play an active role in the teaching of values in schools. Neither were the educators participating in this research able to either identify or promote the values identified in the curriculum. The aim of this research was to develop an instrument to assist educators in identifying values from different belief systems in C2005 (1997); The Revised National Curriculum (2001) and the National Curriculum Statement (2002). Guidelines were developed for the facilitation of the identified values within the OBE curriculum. An empirical research was undertaken regarding the management of values in schools in the Western Cape during June 1999. Possible methods and approaches to values in education in general were identified and the suggested instrument and guidelines to assist educators with the identification of values was developed. The relevance of this study is to assist in-service and pre-service educators In identifying and facilitating different belief and value systems in an OBE education system.
AFRIKAANSE OPSOMMING: Die implementering van Uitkomsgebaseerde Onderwys (UGO) in die Suid-Afrikaanse skoolstelsel het 'n nuwe benadering tot onderwys gebring. Die veelvoudige vakkeuses van die vorige kurrikulum is vervang deur een met agt leerareas. 'n Nuwe kurrikulum wat gefokus is op gesindhede, vaardighede en waardes het op sy beurt die inhoudgebaseerde kurrikulum met 'n prosesbenadering vervang. Opvoeders het nou fasiliteerders van die leerproses geword. Die verwydering van skeidslyne in die Suid Afrikaanse samelewing het tot gevolg gehad dat die diversiteit van die S.A. bevolking tot multikulturele klaskamers gelei het. Skole het die ontmoetingsplek van vele kulture en waardestelsels geword. Die opvoeders wat die leerproses in skole moet fasiliteer, is nie altyd voorbereid op die multikulturele en multireligieuse skoolomgewing nie. Die verandering in die skoolwese vereis dat opvoeders 'n paradigmaskuif betreffende hulle rol as opvoeders moet maak. Die implementering van Kurrikulum 2005(Curriculum 2005,1997; Hersiene Nasionale Kurrikulum (Revised National Curriculum, 2001); Nasionale Kurrikulum Stelling (National Curriculum Statement, 2002) was geensins sonder probleme nie. Heelwat opvoeders het weerstand gebied en baie negatiewe persepsies is behou in verband met die implementering van Uitkomsgebaseerde Onderwys in skole. Die persepsies van opvoeders ten opsigte van die implementeringsfase van die kurrikulum word gemotiveer as gevolg van die onvoldoende opleiding in die voorbereidingsproses .. Die gebrek aan vaardighede om die inhoud van die kurrikulum te fasiliteer, is sigbaar in die opvoeders se onvermoë om waardes in die kurrikulum te identifiseer. Die multikulturele en multireligieuse klaskamer het opvoeders konfronteer met die leerders se waardes vanuit hul verskillende waarde- en oriënteringsomgewings. (belief systems). Dit word belangrik geag dat opvoeders hierdie waardes kan identifiseer sodat die uitkomste van die kurrikulum behaal kan word. Vorige navorsing het aangedui dat opvoeders nie 'n aktiewe rol in die fasilitering van waardes in die skool speel nie. Die opvoeders wat deel was van hierdie navorsing, kon ook nie waardes in die kurrikulum identifiseer of bevorder nie. Die doel van hierdie navorsing was om 'n instrument te ontwerp om opvoeders te help met die identifisering van waardes van die verskillende oriënteringsomgewings (belief systems) in C200S (1997); RNC (2001); NCS(2002) Riglyne is ontwerp vir fasilitering van die geïdentifiseerde waardes in die UGO kurrikulum. Empiriese ondersoek is onderneem met die doelom die hantering van waardes in Wes-Kaapse skole na te vors. Moontlike metodes en benaderings tot waardes in onderwys in die algemeen is geïdentifiseer en 'n instrument om opvoeders te help met die identifisering van waardes, is ontwikkel. Riglyne word voorgestelom opvoeders te help in hulle benadering tot waardes in die kurrikulum.

Full textAbstract:
Over the last two decades, sanitation policy and development has undergone a paradigm shift away from heavily-subsidized, supply-driven approaches towards behavioral-based demand-driven approaches. These current approaches to increase sanitation demand are multi-faceted, requiring multiple stakeholders with varying degrees of interest, knowledge, and capacity. Although efforts exist to increase sanitation access by incorporating engineering design principles with implementation planning approaches, these groups generally work independently without strong connections, thus reducing the potential of their impact. As a result, the design of appropriate sanitation technology is disengaged from the implementation of acceptable technology into communities, disconnecting user preference integration from sanitation technology design and resulting in fewer sanitation technologies being adopted and used. To address these challenges in developing successful interventions, this research examined how user preferences for specific attributes of appropriate sanitation technologies and their respective implementation arrangements influence their adoption and usage. Data for the study included interviews of 1002 sanitation users living in a peri-urban area of South Africa; the surveyed respondents were asked about their existing sanitation technology, their preferences for various sanitation technology design attributes, as well as their perspectives on current and preferred sanitation implementation arrangements. The data revealed that user acceptability of appropriate sanitation technology is influenced by the adoption classification of the users. Through the identification of motives and barriers to sanitation usage that were statistically significant, it exhibited the need to differentiate users who share private sanitation from those use communal sanitation facilities. Results also indicated that user acceptability of appropriate sanitation systems is dependent on the technical design attributes of sanitation. The development of utility functions detailed the significance of seven technical design attributes and determined their respective priorities. An agent-based simulation examined how user preferences for sanitation technology design and implementation influence its adoption and usage. Findings suggest that user acceptability of sanitation technology is dependent on both the technology design and the implementation arrangement being preferred.

Full textAbstract:
Despite the use of earned value management (EVM) techniques to track development progress, federal information (IT) software programs continue to fail by not meeting identified business requirements. The purpose of this logistic regression study was to examine, using IT software data from federal agencies from 2011 to 2014, whether a relationship between schedule variance (SV), cost variance (CV), and actual cost (AC) could predict the success of IT software program, as operationalized by meeting the identified business requirements. The population of interest was 132 IT software programs developed between 2011 and 2014 for federal agencies. The sample source was an archival database located at ITdashboard.gov. The theoretical framework for the study was earned value (EV) project management theory. The EV project management theory is a project performance measurement system that involves integrating cost, schedule, and performance elements for planning and control. EVM contributes to project success by providing early warnings when programs deviate from cost and schedule plans. This study found that only SV was significant (SV days, p = .002). The null hypothesis was rejected, suggesting that a relationship exists between IT program success and the SV, CV, and AC. This study may contribute to social change by increasing the program managers' understanding of EV in federal project management and by decreasing federal spending through successful programs and more cost-efficient use of taxpayers' money.

Full textAbstract:
Model-based systems engineering (MBSE) is an enterprising systems engineering methodology, which in replacing traditional, document-centric systems engineering methods, has the potential to reduce project costs, time, effort and risk. The potential benefits of applying MBSE on a project are widely discussed but are largely anecdotal. Throughout the System Engineering and Project Management industries, there is a strong desire to quantify these benefits, particularly within organizations that are looking to apply it to their complex, system of systems projects. The objective of this thesis was to quantify the benefits that model-based systems engineering presents, particularly in terms of project cost estimates. In order to quantify this qualitative data, statistical analysis was conducted on collected perceptions from industry experts and professionals. The results of this work led to identifying future research that should be completed in order to make MBSE an industry-wide standard for the development and estimation of projects.

Full textAbstract:
Corporate governance (CG) has recently received much attention because of the wave of financial scandals in the early 2000s and the more recent global financial crisis. CG reforms, including laws, codes and listing rules have been established to protect shareholders’ rights and restore investors’ confidence in the capital market. These reforms have largely contributed to the evolution of internal and external governance mechanisms that are aimed at mitigating agency conflicts between managers and shareholders. However, overemphasis has been placed on the monitoring and control dimensions of governance, which may hinder entrepreneurial activities, obscure business prosperity and contribute to a narrow perspective on CG. It has been argued that there is a need to broaden CG beyond compliance (conformance) to a set of rules and laws, to include the performance aspects of governance that focus on strategy and value creation. In other words, governance should not only focus on monitoring managerial performance to ensure accountability to shareholders, but also on mechanisms that motivate management to optimise shareholders’ wealth. Enterprise governance (EG) framework has been introduced to keep the balance between the conformance and performance dimensions of governance. However, few studies address the possible tension between conformance and performance. Moreover, there is no agreement among these studies on the relationship between conformance and performance in the governance context. Arguably, Value-based Management (VBM) is an appropriate approach to address the issue of EG. VBM adopts value creation as an overall objective, develops a strategy that contributes to value creation and integrates it into decision-making. In this way, VBM can act as an effective mechanism for motivating management to maximise shareholder wealth, which works in parallel with other CG mechanisms, to mitigate agency conflicts resulting from the separation between ownership and management. This study aims to develop a contingency framework of EG through operationalising the conformance using CG and performance using corporate entrepreneurship (CE). This framework examines the inter-relationships between VBM, compliance with the Combined Code on Corporate Governance (CCCG), CE and the ultimate effect on organisational performance. More specifically, the study empirically examines the effect of compliance with the CCCG on CE, and whether VBM can achieve a balance between compliance with the CCCG and CE, should a conflict exist. The study also examines whether a fit between contingency variables (company size, agency conflicts, uncertainty, strategy and decentralisation), VBM, compliance with the CCCG codes and CE is associated with organisational performance. To achieve the aim of this study a cross-sectional survey, based on a questionnaire, is conducted to identify the level of VBM implementation, contextual and organisational factors in the large and medium quoted companies in the UK. The questionnaire targets the Chief Financial Officers (CFOs) in these companies as key informants. In addition, a content analysis of the annual reports of the sampled companies is undertaken to measure the level of compliance with the CCCG. Financial data (e.g. organisational performance) have been obtained from the DataStream, Fame and Thomson One Banker databases. Partial Least Squares Structural Equation Modelling (PLS-SEM) is adopted for data analysis and hypotheses testing. The results suggest that VBM implementation is positively associated with agency conflicts, low cost strategies and decentralisation. Compliance with the CCCG is positively associated with agency conflicts and company size. CE is positively associated with company size, uncertainty and differentiation strategies. In addition, the fit between compliance with the CCCG and contingency factors significantly predicts the marketbased performance. The fit between CE and the contingency factors significantly predict the perceived performance. However, the results regarding the effect of VBM on organisational performance are mixed. While VBM has no significant direct effect on the market-based performance, VBM has indirect positive effect on the market-based performance acting through compliance with the CCCG as an intervening variable. VBM is significantly associated with compliance with the CCCG but not with CE. No evidence is found for negative association between compliance with the CCCG and CE. The results support a large number of the proposed relationships between the contingency factors, VBM, compliance with the CCCG and CE. The results also suggest that using both compliance with the CCCG and CE as intervening variables in the relationship between VBM and organisational performance contributes to explaining the mixed results in the VBM literature. In terms of the EG framework, VBM does not keep a balance between conformance and performance. VBM emphasises the compliance with the CCCG (conformance) at the expense of CE (performance). The results did not provide significant evidence of a conflict between compliance with the CCCG and CE, the area which lacks empirical evidence. This study contributes to the literature at different levels. At the theoretical level, this study develops a theoretical model that links a performance management system (PMS), i.e. VBM, to CG practices and CE. This model attempts to bridge the gap between different disciplines, including management accounting, CG and entrepreneurship. Furthermore, combining both the contingency theory and the agency theory lenses contributes to the development of a comprehensive model of EG. At the methodological level, unlike previous studies, this study measures VBM practices on a continuum, rather than categories. Multiple data collection methods are used, and a powerful statistical technique (PLS-SEM) is adopted for data analysis. At the empirical level, the study is conducted in the UK. Though it is different from the US in many aspects, very few studies have been conducted in this context in many research areas such as VBM, CG and CE.

Advanced information and communication technologies, social media, Internet, etc. have tremendously impact on flourishing Internet based Startup around the world. Although some Internet Startups e.g. Facebook, Google, Uber, Airbnb, and Amazon are very successful, but most of the startups fail in their early stage of journey. Previous research findings show that inadequate funding, fierce competition, lack of appropriate strategies and business model, etc. are main reasons for failure of startup firms. Researchers suggest that adequate fund and proper digital business strategies can significantly support these Startups to survive and grow. Digital technologies, which include hardware, software, applications, and interactive communication technologies can significantly enhance and increase capabilities of startups through creating values and competitive advantages. Although, now days digital capabilities in large organization is getting more importance to many researchers, however a few researchers are focusing on investigating the impact of digital capabilities of Internet based startups. The study is conducted to examine how digital technologies create values for Internet based Startups Consultancy. Besides, the study investigates the digital capabilities of and how digital technologies enhance and increase the capability of Internet based Startups Consultancy firms. Five Internet based startup consultancy firms have been investigated. Case based qualitative research methodology has been followed. As research method semi-structured and informal interviews, and observation with the companies have been conducted. The study finds that Internet based digital technologies profoundly facilitate startup companies. From businesss creation to service delivery, digital technologies have enormously increase digital capabilities of internet startup firms. In addition to academic researchers, the outcome of the research will be particularly important for existing startups firms and future entrepreneurs who has plan to establish new startup.

Full textAbstract:
A large number of not for profit organisations use Web technologies for community building, to improve services offered to their public or to generate income. However, the Internet is not a universal panacea and between the hype and counter-hype on the benefits of Web technologies, it is clear there are limits. Some third sector organisations are failing to make the most ofWeb technologies. Thus, it is important to develop a clear understanding of the process of deriving value from those technologies within a not-forprofit environment. This thesis aims at' understanding the way organisational value can be derived from investments in Web technologies within the museum context. Two in-depth case studies of Web projects' implementation processes and their financial, as well as non financial outcomes within two UK museums are presented. The data presented in this thesis was collected through a variety of methods including semi-structured interviews, observation, document review and an evaluation of the two websites. A theoretical approach that takes into account orga~isational and cultural issues embedded in Web-based systems was used in order to uhderstand better the process of acquiring value from the Web activities of the two museums. Thus, a synthesised conceptual framework based on the 'Mangle of Practice' and the 'Limits to Value' model was used for data collection. While the theoretical framework equipped the researcher with a sound basis upon which data collection was conducted, the framework did not offer much assistance in the task of data analysis. For this purpose, techniques were adapted from grounded theory. The two case studies show that although limited resources and the challenges of dealing with the digital content are very important issues for museums, Web systems planning aligned to the museum strategy and assigning the responsibility for the monitoring of Web related initiatives to a senior manager with a broad view of the organisation, as well as the power to initiate changes can improve the value obtained from those initiatives.

Full textAbstract:
Companies are expected to reduce the impact on society caused by its operations while at the same time, generate profit for its stakeholders. One way to satisfy both parts is by creating shared values. As the trend of servitization becomes more popular the ability of Product-Service Systems (PSS) to deliver additional value to customers arises. PSS provides an opportunity for developing a sustainable business model to benefit both the society and the stakeholders. A sustainable PSS can be based on the Triple Bottom Line dimensions, environment, economic, and social. Since the economic and environmental advantages have already been studied for PSS:s, the social aspect is yet to be studied in detail. This thesis focuses on the Occupational Safety and Health (OSH) theme of the social dimension, for PSS:s. Both the ability to improve the social dimension performance and the role it plays in the value proposition for PSS:s were studied. The thesis has been based on a case study on one company in a Business to Business market. It was found that customers seldom demanded or mentioned health and safety aspects for PSS:s, even when an increase of OSH was achieved by the PSS. However, it could also be concluded that all interviewed thought OSH was important for the company and the employees but there were divided opinions regarding OSH, if it would be put in the value proposition or not. By analysing the customer situation and how it operates, companies should use the customizability of PSS:s to better match their requirements and thus develop the value proposition for the PSS. Cost estimations for accidents have been done which showed that one single accident can cause very high costs. It is a good investment to prevent risks which should be communicated when selling PSS:s. Furthermore, it is important to communicate both internally within the firm, and externally to customers, about what health and safety benefits the PSS will contribute with.Företag förväntas att reducera påfrestningarna på samhället och miljön orsakade av deras verksamhet och samtidigt fortsätta generera värde till dess intressenter. Ett sätt att tillgodose båda parter är genom att skapa så kallade delade värden. Då trenden att tjänstefiera blir mer och mer populär finns det möjlighet för ett så kallat Produkt-Service System (PSS) att leverera mervärde till kunderna. PSS ger en möjlighet att utveckla en hållbar affärsmodell som gynnar både samhället och intressenterna. Ett hållbart PSS kan grundas på de tre byggstenarna för Triple Bottom Line, miljö, ekonomi och samhälle. Då de ekonomiska och miljömässiga fördelarna redan har studerats för PSS fokuserar denna studie på hur konceptet står sig för den samhälleliga aspekten. I denna rapport studeras arbetshälsa och säkerhet för PSS, både möjligheten att förbättra den samhälleliga aspekten i Triple Bottom Line samt vilken roll dessa värden spelar för en värdepropositionering för PSS. Rapporten har baserats på en fallstudie på ett företag inom marknaden för Business till Business. Det konstaterades att kunderna sällan efterfrågar eller nämner hälso- och säkerhetsaspekter i förhandlingar om PSS, även när en ökning av arbetshälsa och säkerhet uppnåddes. Hur som helst tyckte alla intervjuade att arbetshälsa och säkerhet var viktigt för företag och anställda men det var trots detta delade meningar om det borde vara en del av värdepropositioneringen eller inte. Genom att analysera kundernas situation och hur de arbetar borde företag använda anpassningsbarheten av PSS för att bättre matcha kundernas önskemål och således utveckla värdepropositioneringen för PSS. Kostnadsberäkningar för olyckor har genomförts som visar att en enskild olycka kan orsaka mycket höga kostnader. Det är en god investering att förebygga risker vilket borde kommuniceras vid försäljning av PSS:s. Det är viktigt att både kommunicera internt inom företaget samt externt till kunderna om de hälso- och säkerhetsaspekter som PSS bidrar med.

Master of Technology: Electrical Engineering

at the Cape Peninsula University of Technology
2014The IEC 61850 standard, “Communication networks and systems in substations” was promulgated to accommodate the need for a common communication platform within substations for devices from different vendors. The IEC 61850 standard proposes a substation automation architecture that is Ethernet-based, with a “station-bus” for protection devices within the substation and a “process bus” where raw data from the voltage and current transformers are published onto the data network using a device known as a Merging Unit. To date, most of the standardization efforts were focused at the station bus level where event-triggered messages are exchanged between the substation automation devices, commonly referred to as Intelligent Electronic Devices (IEDs). These messages are known as Generic Object Oriented Substation Event messages. Equipment from vendors to accommodate the “process bus” paradigm, however is still limited at present. The Centre for Substation Automation and Energy Management Systems was established within the Electrical Engineering Department at the Cape Peninsula University of Technology with one of its objectives being the development of equipment either for simulation or real-time purposes in compliance with the IEC 61850 standard. In order to fulfil this long-term objective of the Centre, an in-depth understanding of the IEC 61850 standard is required. This document details the efforts at acquiring the requisite knowledge base in support of the educational objectives of the Centre and the research project implements a simulation of a merging unit which is compliant with the functional behavior as stipulated by the standard. This limited functional implementation (i.e. non-real-time) of the merging unit, is achieved through the development of a virtualized data acquisition node capable of synthetic generation of waveforms, encoding of the data and publishing the data in a format compliant with the IEC 61850-9-2 sampled value message structure. This functional behavior of the virtual sensor node which was implemented has been validated against the behavior of a commercial device and the sampled value message structure is validated against the standard. The temporal behavior of the proposed device is commented upon. This research project forms the basis for future real-time implementation of a merging unit.

Full textAbstract:
In the last half century, the aerospace industry has seen a dramatic paradigm shift from a focus on performance-at-any-cost to product economics and value. The steady increase in product requirements, complexity and global competition has driven aircraft manufacturers to seek broad portfolios of advanced technologies. The development costs and cycle times of these technologies vary widely, and the resulting design environment is one where decisions must be made under substantial uncertainty. Modeling and simulation have recently become the standard practice for addressing these issues; detailed simulations and explorations of candidate future states of these systems help reduce a complex design problem into a comprehensible, manageable form where decision factors are prioritized. While there are still fundamental criticisms about using modeling and simulation, the emerging challenge becomes ``How do you best configure uncertainty analyses and the information they produce to address real world problems?”
One such analysis approach was developed in this thesis by structuring the input, models, and output to answer questions about the risk and economic impact of technology decisions in future aircraft programs. Unlike other methods, this method placed emphasis on the uncertainty in the cumulative cashflow space as the integrator of economic viability. From this perspective, it then focused on exploration of the design and technology space to tailor the business case and its associated risk in the cash flow dimension. The methodology is called CASSANDRA and is intended to be executed by a program manager of a manufacturer working of the development of future concepts. The program manager has the ability to control design elements as well as the new technology allocation on that aircraft. She is also responsible for the elicitation of the uncertainty in those dimensions within control as well as the external scenarios (that are out of program control). The methodology was applied on a future single-aisle 150 passenger aircraft design.
The overall methodology is compared to existing approaches and is shown to identify more economically robust design decisions under a set of at-risk program scenarios. Additionally, a set of metrics in the uncertain cumulative cashflow space were developed to assist the methodology user in the identification, evaluation, and selection of design and technology. These metrics are compared to alternate approaches and are shown to better identify risk efficient design and technology selections.
At the modeling level, an approach is given to estimate the production quantity based on an enhanced Overall Evaluation Criterion method that captures the competitive advantage of the aircraft design. This model was needed as the assumption of production quantity is highly influential to the business case risk. Finally, the research explored the capacity to generate risk mitigation strategies in to two analysis configurations: when available data and simulation capacity are abundant, and when they are sparse or incomplete. The first configuration leverages structured filtration of Monte Carlo simulation results. The allocation of design and technology risk is then identified on the Pareto Frontier. The second configuration identifies the direction of robust risk mitigation based on the available data and limited simulation ability. It leverages a linearized approximation of the cashflow metrics and identifies the direction of allocation using the Jacobian matrix and its inversion.

Full textAbstract:
This thesis answers how a circular economy-based offering can be designed for increased value creation and decreased environmental impact, compared to a current offering. The study concerns a case company and their current offering of a fire safety solution, namely a 6 kg powder fire extinguisher. The concept Product-Service Systems is used as a base for the research and a foundation of the result.Throughout the study, the method Life Cycle Assessment (LCA) is used as a tool to evaluate and compare the current and the suggested solution in the sense of environmental sustainability amongst different impact categories. It provides a holistic perspective within the study which has been proven by theory to be an important factor when providing a circular economy-based offering. Another important factor is customising the offering to the specific case. This is attended to through an investigation of the company characteristics, the current offering and provider and customer values to find opportunities for the suggested solution. Opportunities found was e.g. a demand for an environmentally sustainable solution and existing infrastructure which can create valuein the future.The process includes, apart from the LCAs, interviews, a workshop at the case company and a survey addressed to end users. The use of visualisation tools such as actors map and Product-Service Blueprint benefits the understanding of both current and suggested solution and provides insights, evaluation and possible improvements. A cost calculation is made to evaluate if the solution is financially making business sense to the provider. Through this thesis, a circular economy-based solution which designs out waste is found. It is proven through the study and LCAs that this solution decreases the investigated environmental impact categories compared to the current existing solution. The suggested solution is based on a refilling process for circulating material which is established through the thesis to be theoretically feasible, hence needs consideration in order to be implementable in reality and make business sense to the provider.Den här studien svarar på hur ett erbjudande baserat på cirkulär ekonomi kan designas för att öka värdeskapande och sänka miljöpåverkan i förhållande till ett existerande erbjudande. Studien baseras på ett företagsfall och deras nuvarande brandsäkerhetslösning, nämligen en 6 kg pulversläckare. I studien involveras teori om Product-Service Systems som en bas för forskningen och en grund för resultatet. Genom studien har metoden Livscykelanalys (LCA) använts som ett verktyg för att utvärdera och jämföra den nuvarande lösningen med den föreslagna i ett miljömässigt sammanhang och med flera olika påverkanskategorier. Detta skapar ett holistiskt perspektiv, vilket teorin visar är en viktig faktor under utvecklingen av ett erbjudande baserat på cirkulär ekonomi. En annan viktig faktor är att anpassa designen av erbjudandet till ett specifikt fall. Detta uppmärksammas genom en undersökning av företagets egenskaper, det nuvarande erbjudandet och leverantörs- och kundvärde för att finna möjligheter till en föreslagen lösning. Sådana möjligheter var till exempel en efterfrågan på miljömässigt hållbara lösningar och en existerande infrastruktur som kan gagna företagets värdeskapande i framtiden. Processen inkluderar, förutom LCA, intervjuer, en workshop, och en kundundersökning adresserad till slutanvändare. Användandet av visualiseringsverktyg, sådana som aktörskarta och Product-Service Blueprint, gynnar förståelsen för både den nuvarande och den föreslagna lösningen och skapar insikter kring utvärdering och möjliga förbättringar. En kostnadskalkyl görs för att utvärdera om lösningen är finansiellt bra för företaget. Genom denna avhandling upptäcks en cirkulär ekonomi-baserad lösning. Studien visar att denna lösning minskar miljöpåverkan för de valda påverkanskategorierna jämfört med den nuvarande lösningen. Den föreslagna lösningen är baserad på att återfylla brandsläckare och därigenom cirkulera material vilket är teoretiskt genomförbart. Dock behövs ytterligare övervägande för att lösningen ska vara implementerbar och för förföretaget realiserbart.

The Healthcare industry, just like any industry, is constantly racing to stay abreast with pace of technological innovations, especially at such a time where the industry is experiencing a strain on the global healthcare infrastructure. Specifically, the evolution of record management systems in the healthcare system has taken a slow and gradual transformation with each stage of transformation carrying over certain aspects and functions of previous stages. A survey of record management practices reveals that record management begun with paper-based records that have since partially been replaced with centralized Electronic Health Records (EHR). With the advent of Electronic Health Records enabled by distributed ledgers, we continue to see the inclusion of traditional paper-based functions beyond centralized EHR functions. Electronic data sharing in the healthcare ecosystem is constrained by interoperability challenges with different providers choosing to implement systems that respond to increasing their productivity. Prioritizing a patient-focused strategy during implementation of EHRs forces providers to implement systems that are more interoperable. A system engineering approach was adopted to guide the development and valuation of candidate architectures from Stakeholder analysis to concept generation and enumeration. Nine (9) key design decisions were selected with their combinations yielding 512 feasible hybrid architectures. In this paper, we proposed a hybrid EHR solution combining distributed ledger technologies and Internet of Medical Things, which contributes towards providing value-based healthcare. Leveraging properties of distributed ledgers and IoMT, the hybrid solution interconnects various data sources for health records to provide real-time record creation and monitoring whilst enabling data sharing and management in a secure manner.

Full textAbstract:
Cloud computing based technology is becoming increasingly popular as a way to deliver quality education to community colleges, universities and other organizations. At the same time, compared with other industries, colleges have been slow on implementing and sustaining cloud computing services on an institutional level because of budget constraints facing many large community colleges, in addition to other obstacles. Faced with this challenge, key stakeholders are increasingly realizing the need to focus on service quality as a measure to improve their competitive position in today's highly competitive environment. Considering the amount of study done with cloud computing in education, very little has been done in examining the needs and the satisfactions of the instructor customer. The purpose of this study was to examine the expectations and perceptions of instructors’ usage of cloud computing based technology on overall quality of service (QoS).
An extension and adaptation of the SERVQUAL model tailored to the higher education environment was introduced for this study. Using the established service quality (SERVQUAL) dimensions (tangibles, reliability, responsiveness, assurance, and empathy), the study investigated the relationship between instructors’ views (perception and expectation) and overall service quality received on their use of cloud computing based technology. A total of 301 online instructors at large Texas community colleges completed a Web-based survey containing previously validated and adapted items. The participants in this study completed four parts of the survey instruments that were used to measure service quality of academic cloud computing technology: Service Quality Expectations, Service Quality Perceptions, Perceived Service Quality and Demographic. The survey questions were answered using a seven-point Likert scale and the survey results were analyzed using descriptive and inferential statistical methods.
The results indicated that the difference between instructors’ perception and expectation affected their perceived service quality of cloud computing based systems. The differences between the expectation and perception on all five SERVQUAL dimensions load to the instructors’ perceived service quality; gender but not age, income or education has significant effect on instructors’ overall perceived service quality. The results of the study create an awareness of instructors’ needs and offer useful feedback to college administrators and institutional planners in their efforts to improve service quality of educational technology initiative in higher education.

Othman, Abdullah. "Exploring the business benefits of regulatory compliance : the case of AML/CFT systems for banking institutions in Malaysia." Thesis, Loughborough University, 2013. https://dspace.lboro.ac.uk/2134/12362.
Full textAbstract:
It has been widely accepted that the banking industry is highly dependent on information technology (IT). Due to its pervasiveness and intertwining nature in most aspects of banking business, IT has also significantly become one of the critical components that facilitate the ability of banking institutions to meet regulatory requirements in an efficient and a cost-effective way. For instance, in the effort to mitigate the activities of money laundering and terrorism financing (ML/TF), various information on banking customers are timely and accurately gathered and analysed through automation. Furthermore, in many instances, IT systems exclusively built to achieve a similar objective are frequently established, and comparable to most IT implementations in the banking institutions, they are often can be equally regarded as a significant investment as well. Viewed from the longstanding debate on the value of IT investments to organisations, empirical research within the IS domain seemed to have placed less emphasis on the possible contribution of regulatory IT implementations. While it is easy to conceive that these IT deployments were never intended to directly benefit banking business from the outset, a study from this perspective should not be disregarded, but instead, warrant to be equally explored. The rationale for this statement can be attributed to the aforementioned assertion regarding the potentially substantial monetary investments required. In addition to this, it may also be due to the high tendency of stringent regulations being enforced in the future, and hence, could inevitably place a significant demand on organisational resources, and further influence their associated opportunity costs. For that reason, this study has attempted to fill the identified research gaps by conducting an investigation from the standpoint of a topical issue regarding anti-money laundering and counter terrorism financing (AML/CFT) implementation efforts within banking institutions. Utilising a conceptual framework that leverages the resource-based view (RBV) to structurally analyse a list of research objectives, empirical evidence of business benefits and the associated capabilities through organisational AML/CFT efforts have indeed been discovered. The benefits are particularly in the form of having the opportunity to leverage various information and infrastructure that were established for regulatory purposes. Further evidence has also suggested that selected AML/CFT alerts have the potential of providing unique opportunity for the organisation to trigger time-critical event-based marketing activities, resulting in a possible improved competitive positioning (ICP). Importantly, by appreciating the insights obtained through the research, a conceptual framework is proposed, which may aid to structurally assess the possible benefits of any organisational regulatory IT implementations.

Full textAbstract:
Som en konsekvens av den tekniska utvecklingen levereras affärssystem alltmer som en molntjänst. Detta innebär att IT-konsulters värdeskapande förändras vid implementering av molnbaserade affärssystem. Besitter IT-konsulterna inte rätt expertis kan det leda till felaktiga beslut samt ineffektiva lösningar. Därmed är det av yttersta vikt att undersöka hur IT-konsulters värdeskapande förändras som konsekvens av implementeringen och användandet av molnbaserade affärssystem. Syftet med studien är att bidra med ny kunskap om hur IT-konsulters värdeskapande kompetens och aktiviteter förändras som konsekvens av implementeringen och användandet av molnbaserade affärssystem. Med hjälp av datadriven tematisk analys har studien undersökt hur IT-konsulters värdeskapande förändras. I studiens slutsats presenteras sex förändringar i hur IT-konsulters värdeskapande kompetens och aktiviteter förändras som konsekvens av implementeringen och användandet av molnbaserade affärssystem. Ett exempel är att IT-konsulters värdeskapande blir att anpassa kundorganisationers affärsprocesser snarare än systemets processer.Because of the technological development, Enterprise resource planning (ERP) systems are increasingly being delivered as a cloud service. This means that IT consultants' value creation may change when implementing cloud-based ERP-systems. If the IT consultants do not possess right expertise, it can lead to erroneous decisions and ineffective solutions. Thus, it is of the utmost importance to investigate how IT consultants' value creation has changed because of the implementation and use of cloud-based ERP-systems. The purpose of the study is to contribute new knowledge about how IT consultants' value-creating skills and activities changes because of the implementation and use of cloud-based ERP-systems. By using a data-driven thematic analysis the study examined how IT consultants' value creation changed because of cloud-based ERP-systems. The study's conclusion presents six changes in how IT consultants' value-creating skills and activities change because of the implementation and use of cloud-based ERP-systems. An example is that IT consultants' value-creation will be to adapt customer organizations' business processes rather than the system's processes.

Full textAbstract:
The current investigation is aimed at the reconstruction and analysis of genome-scale metabolic models. Specifically, it is focused on the use of mathematical-computational simulations to predict the cellular metabolism behavior towards bio-products production. The photosynthetic cyanobacterium Synechococcus elongatus PCC7942 was studied as biological system.
This prokaryotic has been used in several studies as a biological platform for the synthesis of several substances for industrial interest. These studies are based on the advantage of autotrophic systems, which basically requires light and CO2 for growth. The main objective of this thesis is the integration of different types of biological information, whose interaction can be extract applicable knowledge for economic interests. To this end, our study was addressed to the use of methods for modeling, analyzing and predicting the behavior of metabolic phenotypes of cyanobacterium.
The work has been divided into chapters organized sequentially, where the starting point was the in silico metabolic reconstruction network.
This process intent to join in a metabolic model of all chemical reactions codified in genome. The stoichiometric coefficients of each reactions, can be arranged into a sparse matrix (stoichiometric matrix), where the columns corresponds to reactions and rows to metabolites. As a result of this process the first model was obtained (iSyf646) than later was updated to another (iSyf714). Both were generated from data ¿omics published in databases, scientific reviews as well as textbooks. To validate them, each one of the stoichiometric matrix together with relevant constraints were used by simulation techniques based on linear programming. These reconstructions have to be flexible enough to allow autotrophic growth under which the organism grows in nature.
Once the reconstructions were validated, environmental variations can be simulated and we were able to study its effects through changes in outline system parameters. Subsequently, synthetic capabilities were evaluated from the in silico models in order to design metabolic engineering strategies. To do this a genetic variation was simulated in reactions network, where the disturbed stoichiometric matrix was the object of the quadratic optimization methods. As a results sets of optimal solutions were generated to enhanced production of various metabolites of energetic interest such as: ethanol, n-butanol isomers, lipids and hydrogen, as well as lactic acid as the compound which is an interest to the industry.
Furthermore, functionally coupled reactions have been studied and have been weighted to the importance in the production of metabolites. Finally, genome-scale metabolic models allow us to establish criteria to integrate different types of data to help of find important points of regulation that may be subject to genetic modification. These regulatory centers have been investigated under drastic changes of illumination and have been inferred operational principles of cyanobacterium metabolism.
In general, this thesis presents the metabolic capabilities of photosynthetic cyanobacterium Synechococcus elongatus PCC7942 to produce substances of interest, being a potential biological platform for clean and sustainable production.Triana Dopico, J.

Full textAbstract:
Reducing hospital readmissions is critical to the success and sustainability of both hospitals and the communities in which they reside. The purpose of this multiple case study was to explore organizational strategies hospital leaders use to reduce hospital readmissions. The study was limited to hospitals in Southwest Missouri with readmission rates below the state average. Complex adaptive systems was the conceptual framework for the study because of the complex nature and numerous stakeholders of the healthcare system. Data were collected from a purposive sample of 15 hospital leaders via semistructured interviews and an analysis of organizational artifacts. Member checking was used to increase reliability and validity of the results. Data analysis was conducted using Yin's 5 step process including qualitative analysis software to identify major and core themes. The major themes identified in the study included population health, hospital operations and patient interactions, leadership and mission, and barriers to reducing readmissions. The implications for positive social change include the potential to improve services hospital team members provide to patients, which may improve the overall health of the communities they serve. By promoting improved health outcomes for local communities, society benefits through reduction of costs to the federal government and an overall improvement in the health of communities.

Full textAbstract:
Innovating with digital technologies is becoming increasingly necessary as firms seek to remain competitive. Previous scholarship has showed how digital innovation can be managed to be competitive and gain value creation internally. However, the use of diverse digital resources in creating novel services has shaped an opportunity for research in Digital service innovation (DSI). To date, DSI have started to spread in Information System research. However, to understand DSI and its associated value creation dynamics – the relations between internal and external IT-based value creation are unreported. Therefore, in drawing on a qualitative case study of construction firm’s use of DSI capabilities through a Web-based 3D Configurator. This thesis aims to understand its role and dynamics between internal and external IT-based value creation. The results illustrate the role of the Web-based 3D configurator as a fundamental means for delivering both internal and external values. Contrasting previous research, the findings reveal how the firm first needed to achieve external IT-based value creation before internal IT-based values could be realized. This findings contributes to a deeper understanding of DSI and its value creation dynamics, which in the future can be a starting point for creation of new frameworks in managing DSI.

Full textAbstract:
Context: At the core of choosing what features and level of quality to realize, and thus offer a market or customer, rests on the ability to take decisions. Decision-making is complicated by the diverse understanding of issues such as priority, consequence of realization, and interpretations of strategy as pertaining to the short-term and long-term development of software intensive products. The complexity is further compounded by the amount of decision support material that has to be taken into account, and the sheer volume of possible alternatives that have to be triaged and prioritized; thousands or even tens of thousands of requirements can be the reality facing a company. There is a need to develop the functionality that is strategically most significant, while satisfying customers and being competitive, time efficient, cost effective, and risk minimizing. In order to achieve a balance between these factors, all the stakeholders, within an organization, need to agree on the strategic aspects and value considerations to be considered, and their corresponding relative importance. Objective: The objective of this thesis is to provide enhanced decision support for product managers faced with decision-making challenges. This involves, but is not limited to, enhancing the alignment between the product and portfolio management with respect to product strategies, and enabling the use of value as a basis for product management and development related decisions. Method: A number of empirical studies, set in industry, have been performed. The research methods used span from systematic mapping, and systematic reviews to case studies, all aligned to identify possibilities for improvement, devise solutions, and incrementally evaluate said solutions. Close collaboration with industry partners was at the core of the research presented in this thesis. Result: The MASS method presented in this thesis can be used to evaluate strategic alignment and identify possible root causes for misalignment. To strengthen strategic alignment, the Software Value Map and corresponding decision support material, proposed in the thesis, can be used by product managers for making effective and efficient strategic decisions in relation to portfolios, products and process improvement, following a systematic and aligned process. Conclusions: The area of software product management, in the context of market-driven software intensive product development, is a field with unique challenges. The specifics of the solutions are based on industry case studies performed to gauge state-of-the-art, as well as identify the main challenges. The decision support developed takes the form of maps and frameworks that support software product management on product and portfolio level decisions, strategic alignment, value-based requirements selection, and value-based process improvement.

Full textAbstract:
Prenumerationsmodellen är inget nytt fenomen, men har på senare tid spridit sig till nya branscher. Modellen har populariserats till följd av bland annat digitaliseringen, den ökade konkurrensen och nya framväxande kundvärden. Prenumerationsmodellen har fått positiv kritik för sina återkommande och förutsägbara intäkter, men för att det ska bli verklighet krävs det att kunderna stannar kvar. Flertalet prenumerationsföretag har låga utträdesbarriärer, vilket resulterar i att de kontinuerligt behöver skapa ett högt uppfattat värde för att kunderna ska stanna kvar. För att prestera väl och uppnå mål såsom att skapa ett högt uppfattat värde kan företag använda sig av prestationsmätning.Studiens syfte är att bidra med ny kunskap som förklarar hur företag med en prenumerationsmodell använder prestationsmätning i syfte att förlänga kundernas varaktighet.Studien har genomförts genom kvalitativa intervjustudier på fyra prenumerationsföretag inom olika branscher. Genom att studera likheter hos studieobjekten har slutsatser kunnat dras som kan förklara prenumerationsföretag generellt.Studien kom fram till att prenumerationsföretag, i syfte att förlänga kundernas varaktighet, använder prestationsmätning för de attribut som identifierats som särskilt värdeskapande för värdeerbjudandet. På så sätt kan prestationsmätningen användas mer optimalt för att skapa kundvärde och därmed förlänga kundernas varaktighet. Därtill fann studien att mål och mått i stor utsträckning är specifika för enskilda prenumerationsföretag. Studien fann även att värdeerbjudandet tycks påverka hur prenumerationsföretag använder sin prestationsmätning. Genom att prenumerationsföretag använder information från prestationsmätningen i syfte att agera på avvikelser, ökar deras möjlighet att förlänga kundernas varaktighet. Däremot tycks marknadsandel vara ett olämpligt mått för att besvara huruvida prenumerationsföretag skapar kundvärde och bör således inte användas i syfte att förlänga kundernas varaktighet. Slutligen fann studien att prenumerationsföretag använder en kombination av diagnostisk och interaktiv uppföljning och att det ständigt föränderliga kundvärdet innebär att uppföljningen till stor del är interaktiv.

Full textAbstract:
As information continues to grow at a very fast pace, our ability to access this
information effectively does not, and we are often realize how harder is getting to
locate an object quickly and easily. The so-called personalization technology is one
of the best solutions to this information overload problem: by automatically learning
the user profile, personalized information services have the potential to offer users a
more proactive and intelligent form of information access that is designed to assist
us in finding interesting objects. Recommender systems, which have emerged as a
solution to minimize the problem of information overload, provide us with
recommendations of content suited to our needs. In order to provide
recommendations as close as possible to a user&rsquos taste, personalized recommender systems require accurate user models of characteristics, preferences and needs. Collaborative filtering is a widely accepted technique to provide recommendations based on ratings of similar users, But it suffers from several issues like data sparsity and cold start. In one-class collaborative filtering, a special type of collaborative filtering methods that aims to deal with datasets that lack counter-examples, the challenge is even greater, since these datasets are even sparser. In this thesis, we present a series of experiments conducted on a real-life customer purchase database from a major Turkish E-Commerce site. The sparsity problem is handled by the use of content-based technique combined with TFIDF weights, memory based collaborative filtering combined with different similarity measures and also hybrids approaches, and also model based collaborative filtering with the use of Singular Value Decomposition (SVD). Our study showed that the binary similarity measure and SVD outperform conventional measures in this OCCF dataset.

Full textAbstract:
The objective of this thesis is to investigate the flow conditions that lead to coarse grain entrainment at near incipient motion conditions. Herein, a new conceptual approach is proposed, which in addition to the magnitude of hydrodynamic force or flow power, takes into account the duration of the flow event. Two criteria for inception of grain entrainment, namely the critical impulse and critical energy concepts, are proposed and compared. These frameworks adopt a force or energy perspective, considering the momentum or energy transfer from each flow event to the particle respectively, to describe the phenomenon.
A series of conducted mobile particle experiments, are analyzed to examine the validity of the proposed approaches. First a set of bench-top experiments incorporates an electromagnet which applies pulses of known magnitude and duration to a steel spherical particle in a controlled fashion, so as to identify the critical level for entrainment. The utility of the above criteria is also demonstrated for the case of entrainment by the action of turbulent flow, via analysis of a series of flume experiments, where both the history of hydrodynamic forces exerted on the particle as well as its response are recorded simultaneously.
Statistical modeling of the distribution of impulses, as well as conditional excess impulses, is performed using distributions from Extreme Value Theory to effectively model the episodic nature of the occurrence of these events. For the examined uniform and low mobility flow conditions, a power law relationship is proposed for describing the magnitude and frequency of occurrence of the impulse events. The Weibull and exponential distributions provide a good fit for the time between particle entrainments. In addition to these statistical tools, a number of Adaptive Neuro-Fuzzy Inference Systems employing different input representations are used to learn the nonlinear dynamics of the system and perform statistical prediction. The performance of these models is assessed in terms of their broad validity, efficiency and forecast accuracy.
Even though the impulse and energy criteria are deeply interrelated, the latter is shown to be advantageous with regard to its performance, applicability and extension ability. The effect of single or multiple highly energetic events carried by certain coherent flow structures (mainly strong sweep events) with regard to the particle response is also investigated.Ph. D.

Full textAbstract:
Les travaux de cette thèse portent sur l’estimation et la commande décentralisée des systèmes de grande dimension. L’objectif est de développer des capteurs logiciels pouvant produire une estimation fiable des variables nécessaires pour la stabilisation des systèmes non linéaires interconnectés. Une décomposition d’un tel système de grande dimension en un ensemble de n sous-systèmes interconnectés est primordiale. Ensuite, en tenant compte de la nature du sous-système ainsi que les fonctions d’interconnexions, des lois de commande décentralisées basées observateurs ont été synthétisées. Chaque loi de commande est associée à un sous-système qui permet de le stabiliser localement, ainsi la stabilité du système global est assurée. L’existence d’un observateur et d’un contrôleur stabilisant le système dépend de la faisabilité d’un problème d’optimisation LMI. La formulation LMI, basée sur l’approche de Lyapunov, est élaborée par l’utilisation de principe de DMVT sur la fonction d’interconnexion non linéaire supposée bornée et incertaine. Ainsi des conditions de synthèse non restrictives sont obtenues. Des méthodes de synthèse de loi de commande décentralisée basée observateur ont été proposées pour les systèmes non linéaires interconnectés dans le cas continu et dans le cas discret. Des lois de commande robuste H1 décentralisées sont élaborées pour les systèmes non linéaires interconnectés en présence de perturbations et des incertitudes paramétriques. L’efficacité et la validation des approches présentées sont testées sur un modèle de réseaux électriques composé de trois générateurs interconnectésThis thesis focuses on the decentralized estimation and control for large scale systems. The objective is to develop software sensors that can produce a reliable estimate of the variables necessary for the interconnected nonlinear systems stability analysis. A decomposition of a such large system into a set of n interconnected subsystems is paramount for model simplification. Then, taking into account the nature of the subsystem as well as the interconnected functions, observer-based decentralized control laws have been synthesized. Each control law is associated with a subsystem which allows it to be locally stable, thus the stability of the overall system is ensured. The existence of an observer and a controller gain matrix stabilizing the system depends on the feasibility of an LMI optimization problem. The LMI formulation, based on Lyapunov approach, is elaborated by applying the DMVT technique on the nonlinear interconnection function, assumed to be bounded and uncertain. Thus, non-restrictive synthesis conditions are obtained. Observer-based decentralized control schemes have been proposed for nonlinear interconnected systems in the continuous and discrete time. Robust Hinfini decentralized controllers are provided for interconnected nonlinear systems in the presence of perturbations and parametric uncertainties. Effectiveness of the proposed schemes are verified through simulation results on a power systems with interconnected machines

L'objectif de cette thèse est de développer des méthodes de synthèses d'observateurs et des contrôleurs basés sur un observateur pour les systèmes à retard. Différentes classes de systèmes ont été traitées avec différents types de retard. Trois méthodes ont été développées. La première méthode traite des systèmes non linéaires avec des non-linéarités lipschitziennes et consiste à transformer le système d'origine à un système LPV grâce à une reformulation de la propriété classique de Lipschitz. Cette technique est formulée pour les cas continu et discret, respectivement. Nous avons démontré, à travers des exemples numériques, que cette technique offre des conditions de synthèse moins restrictives par rapport aux résultats existants dans la littérature. La seconde méthode est développée pour une classe de systèmes singuliers avec des perturbations. La principale difficulté résidait dans la présence des dérivées des perturbations qui entravent l'analyse de la stabilité et pour laquelle deux approches ont été proposées: une approche Hinf en utilisant une fonctionnelle de Lyapunov-Krasovskii spéciale dépendante des perturbations et une approche basée sur l'utilisation d'un critère de performance W1;2. La dernière méthode est basée sur l'utilisation des matrices de pondération libres pour résoudre le problème de contrôle des systèmes non-linéaires à retards inconnus. La solution proposée fournit une condition de synthèse LMI garantissant la stabilisation du système en boucle fermée malgré la présence du retard inconnu, au lieu d'une inégalité matricielle linéaire itérative ILMI trouvée habituellement dans la littérature.

Full textAbstract:
Syftet med denna magisteruppsats har varit att utforska hur Covid-19 pandemin har påverkat ledarskapet och organisationens riktning. Covid-19 pandemin har påverkar olika delar av ledarskapet. Resultaten visar tydligt att chefer känner sig överbelastade eftersom de måste hantera många administrativa uppgifter och alternerande möten. På grund av brist på tid och balans mellan arbete och privatliv har förmågan att ha en helhetssyn, tolka och ta in perspektiv utifrån och in och inifrån och ut varit en utmaning för ledarna. Resultatet indikerar även på behovet av tydliga kommunikationskanaler mellan ledarna, de anställda och deras kunder om vilka åtgärder som krävs för att anpassa sig till den nya situationen som pandemin har medfört. Under pandemin har organisationerna tvingats att vidta snabba åtgärder baserat på föreskrifterna och begränsningarna från Folkhälsomyndigheten och regeringen. Etablerade digitala kanaler har använts men nya digitala kanaler har behövts identifieras för att skapa interaktion och relationer inom organisationen samt med kunderna. Den snabba omvandlingen till den digitala världen har påverkat organisationens riktning att tänka annorlunda, vara mer flexibel och anpassningsbar till nya oväntade förändringar, såsom pandemin. Organisationerna har använt nyckelindikatorer för att identifiera och få en tydlig bild av hur pandemin har påverkat organisationens riktning internt och externt gentemot sina kunder. Denna nya digitala omvandling har också tvingat kunderna att gå in på nya digitala plattformar och interagera online med organisationerna. Den nya digitala medvetenheten från kunderna har framkallat nya digitala krav och tjänster som i sin tur har resulterat i behov av nya digitala självservice tjänster och en högre och starkare digital kompetens från organisationens kundtjänst. En bidragande diskussion till organisationerna och samhället är att hänvisa till begreppet lönsamhet som en värdeskapande effekt som är hållbar över tid, kopplad till tre element: ledarskap, organisationens riktning och kundbehov.The purpose of this thesis has been to explore how the Covid-19 pandemic has affected the leadership and the direction of the organization. The Covid-19 pandemic has affected various parts of the leadership. The results clearly indicate that managers feel overloaded since they have to handle a lot of administrative tasks and alternating meetings. Due to lack of time and balance between work and private life, the ability to have a holistic view, interpret and take in perspectives from outside-in and inside-out has been a challenge for the leaders. The results also indicated the need for clear communication between the leaders and the employees and their customers about what actions are required in order to adapt to the new situation that the pandemic has imposed. During the pandemic the organizations were forced to take fast action based on the regulations and restrictions from the Public Health Agency and the government. Established digital channels were used but new digital channels had to be identified to create interaction and relations within the organization and with the customers. The fast transformation to the digital world has affected the direction of the organization to think differently and be more flexible and adaptable to new unexpected changes, such as the pandemic. The organizations have used key indicators to identify and get a clear picture of how the pandemic has affected the direction of the organization internally and externally towards its customers. This new digital transformational shift has also forced the customers to enter new digital platforms and interact online with the organizations. The new digital awareness from the customers has induced new digital requirements and services which in turn have resulted in the need for new digital self-services and a higher and stronger digital competence from the organizations customer service. A contributing discussion to the organizations and to the society is to refer to the concept of profitability as a value-creating effect sustainable over time, connected by three elements: leadership, direction of the organization and customer need.

University of Technology, Sydney. Faculty of Business.Knowledge Based Systems (KBSs) have the potential to automate a significant number of the decision making processes across organisations of all types. This represents a unique capability, not available to conventional information systems. It gives KBSs the potential to increase internal efficiency, and to enhance an organisation's competitive position. Despite these potential improvements, the impact of this capability upon an organisation introduces a host of new and complex management issues. Strategic planning for the use of KBSs in organisations is recognised as an important, but neglected area of KBS management research. In practice, KBS development methodologies are used to guide KBS strategic planning. Historically, KBS strategic planning efforts have been poor and are linked to the very high incidence of KBS failure in organisations. While KBS development methodologies may be able to identify potential KBS projects, they are unable to identify which projects have the highest organisational value. The core of the strategic planning problem is that KBS development methodologies adopt current valuation models which do not adequately assess whether investment in a KBS is worthwhile. These valuation models are designed for use in the domain of conventional information systems, but are problematic when applied to KBSs. The unique capability of KBSs to make decisions generates numerous tangible and intangible costs and benefits which cannot be captured by these current valuation models. In addition, these current valuation models fail in three key areas that are critical for adequately assessing KBSs value. First, they do not provide disaggregated information on costs and benefits, many of which are peculiar to KBSs. Second they do not classify these costs and benefits into categories that are meaningful to managers making KBS investment decisions. Third, despite the fact that current valuation models cannot measure intangible costs and benefits, they do not utilise the perceptions of KBS employees to measure them. Using employee perceptions to measure intangible costs and benefits is valid if a recognised psychological model is used to measure perceptions of value. A valuation model specifically designed for KBSs, which addresses these key areas, is needed by managers planning for an organisation's KBS strategy to enable them to identify KBS investments with the highest organisational value. The aim of this thesis is to propose and verify such a model. To achieve this, the case study research methodology was used. The chosen case is a large sales and manufacturing organisation. At the time of study this organisation was developing three KBSs and was interested in being able to measure the relative value of the systems. The study found that the proposed KBS valuation model presented in this thesis overcame the inadequacies of current valuation techniques. First, the results indicate that value of a KBS to an organisation can be assessed by measuring KBS value perceptions of three key employee groups involved in the KBS lifecycle. These groups were found to be: KBS project managers; knowledge domain experts; and KBS users. Employee perceptions of KBS value were measured by adapting the Theory of Reasoned Action (TRA) which reliably produced valid measures of perceived KBS value. Second, the results indicate that the KBS value perceptions were able to be expressed as disaggregated tangible and intangible costs and benefits. Third, these disaggregated costs and benefits were able to be classified into three categories of value found to be common to all KBSs and meaningful to management. These categories are: time; finances; and quality. Finally, a new graphical technique, termed a "KBS value graph", designed to visually portray to managerial decision makers, the perceived value of a KBS was developed. It lucidly portrays perceived KBS value while supporting the three critical areas of KBS valuation.

Multiple-input multiple-output orthogonal frequency division multiplexing (MIMO-OFDM) systems has been widely employed in various wireless communication systems these days. The demand for ever increasing throughput has motivated a lot of related research in this area. Among them, precoding technique has received much attention due to its effectiveness in mitigating the channel impairments and in enhancing the channel capacity. This calls for a closed-loop system where the channel state information (CSI) needs to be feedback from the receiver. By pre-compensating the channel effect at the transmitter, precoding technique can not only improves the bit error rate performance but also reduces the design complexity of MIMO signal detector at the receiver. For OFDM systems, precoding is applied to each sub-carrier. Given the channel matrix of a sub-carrier, a precoding scheme tries to decompose it into a product of three matrices, corresponding to the precoding matrix, equivalent channel matrix, and the receiver matrix, respectively. Popular precoding schemes include singular value decomposition (SVD), geometric mean decomposition (GMD), and uniform channel decomposition (UCD). In this thesis, we focus on the most widely SVD precoding scheme and present a unified design, which incorperates the QR decomposition (QRD) scheme for signal detection and the SVD scheme for precoding into the same hardware framework. The proposed design can support a 4 × 4 MIMO system with high throughput opeartions. The design starts with the algorithm development, where the computing complexity is largely reduced. A bi-diagonalization pre-processing is performed first followed by iterative nullification sweeps to achieve a diagonal matrix. To support a constant throughput implementation, the number of nullification sweeps is fixed but a convergence detection mechanism is employed. Once the iteration converges, a bypassing scheme is activated to suspend the remaining computations for power saving. The design is carefully scheduled and pipelined so that maximum degree of computing parallelism can be achieved with minimum hardware complexity. At the circuit level design, low complexity and pipelined coordinate rotations digital computers (CORDICs) modules are employed to implement the required trigonometric functions. The proposed design is capable of completing one 4 × 4 QRD or SVD computation every 4 clock cycles. The design is further implemented result using a TSMC 90-nm CMOS process technology. The result shows that the design consists of 451.53k logic gates and can operate up to 143 MHz. This suggests a throughput rate of 4 × 4 35.75M matrix decompositions per second. The total power consumptions are 93.54 mW and 164.48 mW for QRD and SVD mode computations, respectively.

Full textAbstract:
With the emergence of a new service delivery model, Software-as-a-Service (SaaS), interest in quality management in the planning and operation of SaaS systems is increasing significantly. Most current quality management approaches for SaaS focus primarily on the perspective of service provider. They largely ignore the perspective of service customer as well as the nature of ongoing business relationship between the service provider and customer. Based on an extensive exploration of this relationship, the thesis research makes contributions in the following four areas:
1. A theory of SaaS business relationships is introduced by integrating an adapted quality paradigm with the notion of value co-creation (co-value) for the service provider and customer. In the theory, we define a specification of four quality-based service types (Ad-hoc, Defined, Managed and Strategic).
2. The theory is used as the foundation for building a model that assists service customers in SaaS evaluation in support of service planning and ongoing operations.
3. Based on the model, an evaluation tool is designed and used in a particular service area. As an example, a case study is undertaken to assist the decision making of email service adoption in the University of Alberta.
4. Two surveys are conducted to assist in the building and evolution of the evaluation model, as well as in the use of an email service evaluation tool.
