An empirical comparison of supervised machine learning techniques in bioinformatics

Research in bioinformatics is driven by the experimental data. Current biological databases are populated by vast amounts of experimental data. Machine learning has been widely applied to bioinformatics and has gained a lot of success in this research area. At present, with various learning algorithms available in the literature, researchers are facing difficulties in choosing the best method that can apply to their data. We performed an empirical study on 7 individual learning systems and 9 different combined methods on 4 different biological data sets, and provide some suggested issues to be considered when answering the following questions: (i) How does one choose which algorithm is best suitable for their data set? (ii) Are combined methods better than a single approach? (iii) How does one compare the effectiveness of a particular algorithm to the others

Topics in Supersymmetry: Implications for Cosmology and Non-Perturbative Studies on a Spacetime Lattice

Moduli fields, scalar fields which parametrize different vacuum states of a given theory, are commonly predicted to exist within compactifications of UV complete theories, and in particular those theories exhibiting supersymmetry. But if such theories\u27 dynamics are present during the inflationary phase of the universe and thereafter, what are the implications for cosmology and the evolution of the universe? In this thesis a review is presented on generic consequences of the presence of these scalar fields during inflation and the post-inflationary era of the universe. An unexpected consequence arises in the study of dark matter production, where a deviation from the usual thermal production mechanism is shown to be required. In addition to studies in cosmology, the dynamics of a twisted construction of supersymmetric lattice quantum field theory is explored. An analysis of the fermionic sign problem is presented and it is shown to be absent in the studied formulation. A first study of the phase structure of supersymmetric N = 4 supersymmetric gauge theory is also presented

Professionalising public relations: A history of Australian public relations education, 1985 - 1999

This thesis is concerned with public relations education in Australia. It focuses on 1985–1999, as in these years there was significant growth in education and the Public Relations Institute of Australia (PRIA) sought greater regulation and jurisdiction over public relations activity. Existing historical scholarship focuses on the evolution of the Australian public relations industry towards professional status, and tertiary education is perceived to confirm the field’s professional standing. In contrast, I consider the development of public relations education in a broader social context and the involvement of the PRIA in tertiary education. This thesis aims to investigate the role of public relations education in the professionalisation of public relations in Australia. It uses a qualitative approach, combining archival research, focusing on the previously unstudied archives of the PRIA’s National Education Committee, and interviews with practitioners and educators. This thesis provides an analysis of how, and why, the PRIA sought to regulate public relations education. The use of historical sociology allows the findings to be interpreted in relation to broader societal structures and institutional processes, such as the expansion of the Australian higher education sector, the PRIA’s preoccupation with professional status, and the increase in female practitioners. In developing a critical account of Australian public relations education, this thesis argues that higher education was pivotal to the PRIA’s professional project. The findings confirm the constitution of public relations knowledge and its institutionalisation in the Australian academy were dynamic and contested, and that the PRIA’s professional drive informed its attempts to regulate the transmission of that knowledge. A significant finding is the ambivalent attitudes towards gender and education, given the increasing number of female graduates. These findings contribute a unique Australian perspective to the global public relations scholarship on history and professionalisation and allow a reconceptualisation of the development of public relations in Australia

Outer suburban/interface services and development committee inquiry into liveability options in outer suburban Melbourne

This report presents a range of options for enhancing the liveability of Melbourne’s outer suburbs. Melbourne has an international reputation as one of the world’s most liveable cities. However, many areas within Melbourne’s outer suburbs currently lag behind the rest of Greater Melbourne on a range of liveability measures. On a number of those measures, the gap is growing. This situation is primarily due to the rapid pace at which Melbourne’s outer suburbs have expanded in recent years. There are a range of options for preserving and enhancing the liveability of Melbourne’s outer suburbs, many of which are increasingly being adopted by residents, community groups and local governments. The Government of Victoria has also indicated that preserving and enhancing the liveability of Greater Melbourne will be a major priority for the new Melbourne Metropolitan Planning Strategy
