This dissertation provides a review of the relevance of operational risk in the banking industry and attempts to determine whether operational risk management is perceived as a moderating factor on the relationship between critical success factors and competitive advantage in banking industry. A survey was of 399 senior managers of fully licensed banks in Hong Kong. They were asked to indicate the perceived critical success factors, which include operational risk management as one of the variables in the banking industry. In addition, they were also asked to evaluate the relevance of operational risk in their industry and describe their bank's operational risk management practice. / Thesis (DBusinessAdministration)--University of South Australia, 2006.

The outsourcing market, especially Business Process Outsourcing (BPO), is growing every year. For decades, companies have successfully used outsourcing to generate significant savings. However, discussions with any employee will reveal some resentment of outsourcing. The aim of the study has been first to improve the understanding of some salient difficulties in Business Process Outsourcing relationships, with special reference to the perceived challenges of managing and monitoring Service Legal Agreements in Swiss banking, and second to assist outsourcing banks and service providers in formulating and managing their outsourcing contracts. The study was designed to obtain, through interviews, descriptions and perceptions of experts in Swiss Banking Business Process Outsourcing. Given the nature of the topic but also because of practical constraints, the investigator elected to use a qualitative, interpretative, social constructionist research framework. An extensive review of the literature revealed that a variety of definitions of in- and out-sourcing exist. Some of these terms were used in academic writings and the business press interchangeably and had to be defined. Twenty-two practitioners were interviewed. The data were analysed and interpreted with the help of qualitative analysis software (NVivo). Subsequently, I compared my findings with those of the literature reviewed. Furthermore, a gap in the literature, namely that it generally does not deal with the perceived quality of the relationship, could be addressed and practical approaches for managing BPO relationships are suggested. / Thesis (DoctorateofBusinessAdministration)--University of South Australia, 2007.

Digital filter banks have found in a wide variety of applications in data compression, digital communications, and adaptive signal processing. The common objectives of the filter bank design consist of frequency selectivity of the individual filters and perfect reconstruction of the filter banks. The design problems of filter banks are intrinsically challenging because their natural formulations are nonconvex constrained optimization problems. Therefore, there is a strong motivation to cast the design problems into convex optimization problems whose globally optimal solutions can be efficiently obtained. The main contributions of this dissertation are to exploit the convex optimization algorithms to design several classes of the filter banks. First, the two-channel orthogonal symmetric complex-valued filter banks are investigated. A key contribution is to derive the necessary and sufficient condition for the existence of complex-valued symmetric spectral factors. Moreover, this condition can be expressed as linear matrix inequalities (LMIs), and hence semi-definite programming (SDP) is applicable. Secondly, for two-channel symmetric real-valued filter banks, a more general and efficient method for designing the optimal triplet halfband filter banks with regularity is developed. By exploiting the LMI characterization of nonnegative cosine polynomials, the semi-infinite constraints can be efficiently handled. Consequently, the filter bank design is cast as an SDP problem. Furthermore, it is demonstrated that the resulting filter banks are applied to image coding with improved performance. It is not straightforward to extend the proposed design methods for two-channel filter banks to M-channel filter banks. However, it is investigated that the design problem of M-channel cosine-modulated filter banks is a nonconvex optimization problem with the low degree of nonconvexity. Therefore, the efficient semidefinite relaxation technique is proposed to design optimal prototype filters. Additionally, a cheap iterative algorithm is developed to further improve the performance of the filter banks. Finally, the application of filter banks to multicarrier systems is considered. The condition on the transmit filter bank and channel for the existence of zero-forcing filter bank equalizers is obtained. A closed-form expression of the optimal equalizer is then derived. The proposed filter bank transceivers are shown to outperform the orthogonal frequency-division multiplexing (OFDM) systems.
