- Description: "Group decision-making usually involves a process of discussion and evaluation of alternatives. Important aspects of a group decision support system are: freedom to participate; the ability to explicitly present points of view; the ability to augment or oppose views by supporting evidence and reasoning; and the ability to use and consider other additional views .... The overall aim of this work is to develop an approach that can alleviate some of the problems associated with group commuication and consensus decision-making by effectively supporting group discussions towards consensus. Towards achieving this goal we have developed an approach called ConSULT (Consensus based on a Shared Understanding of a Leading Topic) as a computer-mediated framework to allow argumentation, collection and evaluation of discussion and group decision-making. This approach employs existing theories and techniques in computer-mediated communication, argumentation, Delphi and voting." -- Abstract.

- Description: "Longitudinal studies, where data is collected by measuring the same experimental units several times over a relatively long period, are becoming increasingly common. Conventional statistical approaches have limitations when applied to the analysis of longitudinal data ... Practical limitations of longitudinal analysis that relate to missing data and large data set sizes were explored in this thesis with the application of a sampling technique known as Ranked Set Sampling (RSS). We developed this sampling method, which has not previously been applied to longitudinal data, for fixed and mixed-effects models. This thesis also illustrated inference techniques to estimate these models after selecting sample units by RSS."

Statistical detection techniques to reduce confounding by association (co-medication) and confounding by indication in the Australian spontaneous reporting system
- Authors: Barty, Simon
- Date: 2005
- Type: Text , Thesis , PhD
- Full Text: false
- Description: This research is the incorporation and melding of classical and Bayesian statistical techniques into an iterative methodology aimed at reducing two major confounding issues in Adverse Drug Reactions (ADRs), confounding by association (drug therapy) and confounding by indication (medical condition) to assist in the detection of signals. [...] This study highlights the ability of the STATFILE algorithm to detect drugs that are potential signals. More importantly, it also flags those drugs that are considered to be bystander drugs or noise, consequently reducing confounding by association. [...] This work highlights the significance and viability of an automated signal detection system and its practical application for the Australian spontaneous reporting of ADRs scene and potentially the international scene.

Manifestation of token behaviours on corporate boards; a qualitative study
- Authors: Bhardwaj, Sneh
- Date: 2021
- Type: Text , Thesis , PhD
- Full Text: false
- Description: As boards are central to organisational performance, an ineffective board functioning has long remained a matter of concern among corporate governance researchers, board practitioners, policy makers and the media not only in India – the context of this study – but also across the regions of Asia-Pacific, Africa, Europe, and the Americas. An important aspect of boards’ ineffective working concerns directors’ token board behaviours. This debate in corporate governance circles however continuously adheres to a gender/minority-focused approach, attributing token board behaviours to the gender of minority directors on corporate boards (i.e., women directors). The study aims to examine, firstly, the selection process and criteria for corporate board directors’ appointments in India. Secondly, this thesis examines how the quota appointees are being recruited, integrated, and treated by corporate boards in India, to explain the ensuing participation of quota appointees. The third contribution is (from the third and fourth study aims) a more nuanced explanation of token board behaviours of Indian men and women directors (beyond the commonplace explanation of token board behaviours based on the number of minority directors on corporate boards) from an in-depth examination of directors’ board conduct. The research draws on three theories. Firstly, the resource dependence theory (RDT) lens is used to review the literature on board appointments. RDT supports an argument that board composition impacts board processes, dynamics, and culture, and vice versa. Secondly, the token theory, which identifies the inclusion of minority groups as a perfunctory gesture, is used as a putative explanation for effective/ineffective board participation of directors. Thirdly, the institutional theory is applied to examine the findings related to directors’ quota-based board appointments in response to institutional pressures, namely, coercive, normative, and mimetic. An interpretative phenomenological approach informs this study’s research design. I developed four research questions and, to answer these, conducted twenty-seven semi-structured interviews with Indian board directors to obtain first-hand narration of lived experiences in this context. The findings indicate that a majority of directors consider the pre-, during and post-meeting board dis-engagement, impaired board culture, poorly structured board processes, lacunae in director selection including those of the law-supported women directors and board inexperience of directors as determinants of token behaviour on boards, rather than attributing this understanding to the gender of board minorities alone. These results provide an enhanced understanding of token behaviours manifested by board directors. In so doing, new proposals for restructuring directors’ selection processes, quota law’s implementation, directors’ board roles and boards’ internal functioning are offered. The research has implications for regulators, companies, and governments attempting to enhance the corporate governance effectiveness of corporate boards by putting an end to directors’ token behaviours.

Organisational engagement of individuals with younger-onset dementia : maximising beneficial workplace outcomes
- Authors: Carino, James
- Date: 2023
- Type: Text , Thesis , PhD
- Full Text: false
- Description: This thesis concerns individuals who develop dementia symptoms before 65 years of age (called younger-onset dementia, or YOD) while employed, which has significant personal, financial and social effects due to the commitments and responsibilities of families and work. This thesis aims to identify employment-related work strategies to allow people with dementia to continue to work. Four linked studies consistent with the study aim were designed and implemented. In Chapter 3, Study 1, a review of employer approaches to employees with dementia, evaluated nine studies related to dementia and work. The main analysis extracted, grouped and classified employer actions towards employees with dementia in these studies. Two in three employer responses to employees with dementia were ineffective in supporting employees. Poor understanding of the difficulties of those living with dementia appeared to be the main cause. Better knowledge among individuals experiencing dementia symptoms and their employers is needed. In Chapter 4, Study 2, a review of guidance materials related to dementia in the workplace sought to identify and review the availability, structure and content of information to support employees or employers dealing with dementia. Guidance information published by dementia organisations in English-speaking countries such as Australia, Canada, New Zealand, Singapore, the United Kingdom (England, Scotland and Ireland) and the United States of America was analysed and compiled. Dementia websites were found to offer relevant, high-quality content, but this can be fragmented and difficult to find. Few organisations covered the range of relevant content. Most information was aimed at employees with dementia symptoms rather than their employers. Information gaps for employees with dementia included the importance of early diagnosis and assistive technology applications. Employer information gaps included workplace identification of dementia, employee retention and managing the wider work team around the person with dementia. Chapter 5 addressed Study 3, employer approaches to employees with dementia at work. This chapter extended existing research exploring the experience of dementia at work. Four groups were engaged in semi-structured interviews: (1) employers and human resource (HR) managers; (2) professionals supporting employers such as HR consultants; (3) employees with dementia who were working or had left work within the past two years; and (4) professionals supporting people living with dementia. The study identified employee and employer actions and assessed how dementia could be managed using relevant information and approaches to maintain viable employment. As well as the need for greater awareness of workplace cognitive impairment, this study identified solutions to prolong employment. Suggestions included using relevant expertise and external peer support, implementing self-management and personal strategies, raising employer awareness of employee rights and employer responsibilities, employee engagement in decisions about them and their work and assistance with the transition from work. An analytical approach, considering the person, task and organisation may assist in devising more effective employer implementation approaches. Study 4, guidance model document feedback (presented in Chapter 6), evaluated two model guidance documents (one for employers, the other for employees) developed from Studies 1, 2 and 3. This study aimed to determine the relevance and completeness of the content and identify potential enhancements. Study 3 participants were recontacted for this study. The proposed documents were received positively. Suggested improvements included care in the use of terms such as ‘dementia’, moving beyond ‘dementia friendly’ to inclusivity and clearer specification of the responsibilities of HR practitioners and employers. Chapter 7 placed the findings across the four studies into the context of increased workplace and societal attention to mental health, wellbeing, cognitive fitness and neurodiversity. Growing awareness of these issues is argued to be positive for future workplace understanding, acceptance and management of conditions such as dementia and cognitive impairment. HR leadership and expertise in dealing with dementia in the workplace are pertinent to achieving this goal. This thesis elaborates on the practical importance of information and communication in understanding cognitive impairment at work. Awareness that individuals in the early stages of cognitive difficulties maintain the capacity to continue to work can be improved. A review of information designed to support workplace decision-making has identified content and pathways to improve workplace knowledge and awareness. In conclusion, dementia at work can be managed by integrating awareness of dementia with mental health and cognition in workplaces. Greater attention to the diversity of cognitive abilities and processes in organisations can improve the life experience of employees living with dementia, their contribution to work, overall work performance and satisfaction.

The effect of website, face-to-face, and combined programs on physiological, psychological, and lifestyle risk variables for cardio-vascular disease
- Authors: DeAraugo, Jodi
- Date: 2005
- Type: Text , Thesis , PhD
- Full Text: false
- Description: "Although a multitude of preventative programs have been utilised worldwide to modify cardiovascular risk factors, none have included internet based interventions. Study 1 aimed to compare internet based (n = 21), face-to-face (n = 27), and combined (n = 21) treatment groups with a naturally occurring control group (n = 24) on physiological, psychological, and lifestyle risk variables for cardiovascular disease across 6-months, and to determine if there were relationships between changes in the psychological and physiological variables over time. Results indicated that the internet based group had significantly greater social reciprocity than the face-to-face group. Significant time effects were noted for heart rate, stress, depression, anxiety, reciprocity, anger expression-out, anger expression-in, anger control-out, and anger control-in. Results also demonstrated that increases in reciprocity and anxiety, and decreases in anger expression-out, were related to increases in heart rate. "In contrast, less anger suppression was a significant predictor of greater systolic blood pressure. However, there were no significant results for group, time, or predictive value for the other psychological, physiological, and lifestyle risk variables. A follow-up study examined the effects of unstructured (n = 13) and highly structured (n =14) internet based programs on physiological, psychological, and lifestyle risk variables for coronary heart disease over 6-months. It also investigated if there were relationships between changes in the psychological and physiological variables over time. Participants stages of change were assessed in relation to psychological and lifestyle risk variables. Results showed that the unstructured group scored significantly higher on anger-expression-out than the highly structured group and that the unstructured groups alcohol usage significantly reduced over time. "The remaining psychological, physiological and lifestyle risk variables did not produce significant group, time, or predictive changes. The stage of change results indicated no significant group or time effects. Results indicated that greater angry reaction scores were predictive of higher heart rate and increased stress scores were predictive of higher diastolic blood pressure. The critical psychological variables predictive of poorer cardiovascular functioning should be targeted in future interventions."

'You Beauty' Alex Jesaulenko An historical exploration of the migrant who became a legend
- Authors: Eddy, Daniel
- Date: 2019
- Type: Text , Thesis , PhD
- Full Text: false
- Description: The Austrian-born Alex Jesaulenko played football in the Victorian Football League (VFL) from 1967 to 1981. His rise to national prominence emerged during a period of great change within both Australian society and Australian rules football. This thesis, through a critical biographical approach, examines for the first time Jesaulenko’s early life, looking at his migrant experience and the role that Australian rules football played in aiding his integration into Australian society. It is not a kick-and-handball analysis of Jesaulenko’s entire football career; that has been extensively covered within copious amounts of primary and secondary sources. Instead, it explores his migrant journey – an important aspect of Jesaulenko’s life which has been largely overlooked – and the key developmental years of sporting education prior to emerging as a VFL champion. It concludes with one of, if not the most, iconic moments in the game’s history: Jesaulenko’s mark in the 1970 VFL grand final, which cemented his name within the Australian sporting consciousness. Australian rules football, and sport more generally, holds a unique place within society. Footballers, it can be argued, are archetypes for our daily dreams and aspirations; exalted figures that we afford status which few will experience in their everyday lives. Therefore, it is through the prism of Jesaulenko’s journey that we can learn more about the role Australian rules football has played for migrants integrating into Australian society.

Barley non-starch polysaccharide content and its relationship with kernel hardness and water uptake
- Authors: Gamlath, Jayantha
- Date: 2009
- Type: Text , Thesis , PhD
- Full Text: false
- Description: Harder kernels in barley are thought to be a factor affecting the modification of the endosperm during malting by restricting water and enzyme movement within the endosperm. The traditional method used in the malting industry to determine barley endosperm vitreousness is by visual assessment. Since this method is subjective, laborious and requires training, an alternative method is needed. Similarly, the causes and factors influencing kernel hardness are uncertain. The prime objectives of this study were: to identify an appropriate method to quantify kernel hardness; investigate the relationship between kernel hardness and endosperm composition; and to investigate the relationship between barley variety and environmental influences on endosperm composition in relation to the kernel hardness of malting barley.

‘A life less ordinary’ : to downshift or not to downshift : why people make or don’t make decisions to change their lives?
- Authors: Goulding, Carmel
- Date: 2022
- Type: Text , Thesis , PhD
- Full Text: false
- Description: A fundamental condition of modernity is the expansion of choice, with the range of options widening on how we live our lives, and whom we spend our time with. We are no longer defined by a clear set of social ties which bind us to our life situation. We can choose our friends, geographic locality, employment and, perhaps, our gender and that of our children. We can if we choose, substantially alter the way we live, and some people do as is evidenced by the phenomenon popularly known as downshifting. Downshifting involves a voluntary reduction in working time and income, in return for a slower pace of life and increased free time and is generally conceived as a conscious change in ways of consuming, working and relating. This thesis seeks to explore the questions why people downshift and how the decision is sustained over the life course. It does this through a two-staged, longitudinal qualitative study of people who have downshifted in Australia and the United Kingdom. The thesis is built on the assumption that downshifting is a rational choice. People do calculate risk and constraints and the range of options as part of the decision process. However, explanations of action firmly rooted in economic rationality do not adequately account for what influences and shapes preferences and pays little attention to the micro worlds of individual choice-making. This dissertation offers an account of social action built around the concept of bounded rationality whereby the fluid, linked communities evident in modern life, act as a mediating factor in the initial choice and as well as over the downshifter life course. To date, there has been limited empirical research on the life course of downshifters. This doctoral study fills the knowledge gap.
