Saying ‘No’: A Biographical Analysis Of The Experiences Of Women With A Genetic Predisposition To Developing Breast/Ovarian Cancer Who Reject Risk Reducing Surgery, Doreen Molloy

Theses: Doctorates and Masters

Background: Genetic technologies have identified some of the genes implicated in cancer susceptibility. Women with mutations in breast/ovarian cancer-susceptibility genes (BRCA1 and 2) have a lifetime combined risk of breast/ovarian cancer of more than 80%. Risk reducing surgery (RRS) reduces cancer risk by as much as 90% in high risk populations. Despite this, some BRCA1/2 mutation-positive women say no to RRS.

Purpose: To illuminate an understanding of why women at high risk of developing breast/ovarian cancer say no to risk reducing surgery (RRS).

Design: Denzin’s (1989) interpretive biography was combined with Dolby-Stahl’s (1985) literary folkloristic methodology to provide a contextualised …

Accessibility Of Thai University Websites: Awareness, Barriers And Drivers For Accessible Practice, Rattanavalee Maisak

Theses: Doctorates and Masters

Governments and organizations have to respond to a range of legislative and policy initiatives intended to promote equal opportunity for all. The Thai government has passed a number of laws which aim to protect its citizens from discrimination and from breaches of their human rights by government departments and agencies. The Persons with Disabilities Education Act B.E. 2551 (2008) and the Thailand Information and Communication Technology (ICT) Policy Framework (2011-2020) required government agencies to delivery equal education and access to online information for all Thais. Most Thai universities receive government subsidies, and therefore have an obligation to contribute to national …

Motherhood First: An Interpretive Description Of The Experience Of Mature Age Female Students With Dependent Children At One Regional University Campus In Australia, Amanda Draper

Theses: Doctorates and Masters

This study explored the experience of mature age female students with dependent children at one regional university campus in Western Australia, Edith Cowan University South West (ECUSW). These students are one of many student groups whose experience differs to that of more traditional students such as young, unmarried, and well-supported school-leaver students. Although all students enter university with experiences that make them valuable to the university institution, mature age female students with dependent children enter university with unique knowledge, experiences and attitudes making them potentially valuable contributors to their own and others’ learning (Martins & Anthony, 2007). Whilst at university, …

Early Intervention Of Parent-Infant Interactions In Preterm Infants: A Systematic Review, Stacey Osborne

Theses : Honours

Every year approximately 15 million babies are born preterm. These infants are at an increased risk of language, and other developmental delays due to their immature brain development and higher incidence of brain abnormalities. They also have poorer health outcomes in the early stages of life which may go on to hinder successful parent-infant interactions. Successful parent-infant interactions are important for infant developmental outcomes such as language, cognition and behaviour. While interventions targeting the promotion of positive interactions have been found to have positive effects in a number of populations to date, interactions involving preterm infants have not been explored. …

Ambiguous Optimistic Fair Exchange: Definition And Constructions, Qiong Huang, Guomin Yang, Duncan S. Wong, Willy Susilo

Research Collection School Of Computing and Information Systems

Optimistic fair exchange (OFE) is a protocol for solving the problem of exchanging items or services in a fair manner between two parties, a signer and a verifier, with the help of an arbitrator which is called in only when a dispute happens between the two parties. In almost all the previous work on OFE, after obtaining a partial signature from the signer, the verifier can present it to others and show that the signer has indeed committed itself to something corresponding to the partial signature even prior to the completion of the transaction. In some scenarios, this capability given …

Research Collection Yong Pung How School Of Law

Montgomery v Lanarkshire Health Board (“Montgomery”)1 is about a baby being born with severe disabilities. Expectant mothers of small build and suffering from diabetes,2 such as the plaintiff, run the risk of shoulder dystocia, that is – the situation of the baby’s shoulders being unable to pass through the pelvis in a normal delivery.3 In this case, the patient was not told of the risk of shoulder dystocia as, in the doctor’s opinion, the possibility was very small. The doctor was not inclined to warn as most mothers, if told would opt for a ceasarean section and that would deprive …

Semiparametric Analysis In Conditionally Independent Multivariate Mixture Models, T. Wrobel, Denis H. Y. Leung, J. Qin, T. Hettmansperger

Research Collection School Of Economics

The conditional independence assumption is commonly used in multivariate mixture models in behavioral research. We propose an exponential tilt model to analyze data from a multivariate mixture distribution with conditionally independent components. In this model, the log ratio of the density functions of the components is modeled as a quadratic function in the observations. There are a number of advantages in this approach. First, except for the exponential tilt assumption, the marginal distributions of the observations can be completely arbitrary. Second, unlike some previous methods, which require the multivariate data to be discrete, modeling can be performed based on the …

State-Owned Enterprises In Singapore: Historical Insights Into A Potential Model For Reform, Cheng-Han Tan, Dan W. Puchniak, Umakanth Varottil

Research Collection Yong Pung How School Of Law

This article argues that the Singapore GLC Model is so closely intertwined with Singapore’s idiosyncratic history and unique regulatory culture that, although the model has been extremely successful within Singapore, transplanting it to China could be difficult. The article also explores the extent to which the success of the Singapore GLC Model and China’s ambition to emulate it challenge notions that corporate governance systems are converging towards a market-oriented (American) model of the shareholder centric corporation and the extent to which the success of the Singapore GLC Model challenges the basic conception that private enterprise rather than the state is …

Improving Internet Security Through Mandatory Information Disclosure, Qian Tang, Andrew B. Whinston

Research Collection School Of Computing and Information Systems

Although disclosure has long been considered as a solution to internalize externalities, mandatory security information disclosure is still in debate. We propose a mandatory disclosure mechanism based on existing data. The information is disclosed as straightforward rankings of organizations for users to understand, interpret, and make comparisons. As a result, the disclosure can influence organizations through reputational effects. We created a public website to disclose information regularly and conducted a quasi-experiment on outgoing spam to test the effectiveness of our mechanism on four matched country groups. For each treated country, we released the ranking list of top 10 most spamming …

Solving Uncertain Mdps With Objectives That Are Separable Over Instantiations Of Model Uncertainty, Yossiri Adulyasak, Pradeep Varakantham, Asrar Ahmed, Patrick Jaillet

Research Collection School Of Computing and Information Systems

Markov Decision Problems, MDPs offer an effective mechanism for planning under uncertainty. However, due to unavoidable uncertainty over models, it is difficult to obtain an exact specification of an MDP. We are interested in solving MDPs, where transition and reward functions are not exactly specified. Existing research has primarily focussed on computing infinite horizon stationary policies when optimizing robustness, regret and percentile based objectives. We focus specifically on finite horizon problems with a special emphasis on objectives that are separable over individual instantiations of model uncertainty (i.e., objectives that can be expressed as a sum over instantiations of model uncertainty): …

Are Features Equally Representative? A Feature-Centric Recommendation, Chenyi Zhang, Ke Wang, Ee-Peng Lim, Qinneng Xu, Jianling Sun, Hongkun Yu

Research Collection School Of Computing and Information Systems

Typically a user prefers an item (e.g., a movie) because she likes certain features of the item (e.g., director, genre, producer). This observation motivates us to consider a feature-centric recommendation approach to item recommendation: instead of directly predicting the rating on items, we predict the rating on the features of items, and use such ratings to derive the rating on an item. This approach offers several advantages over the traditional item-centric approach: it incorporates more information about why a user chooses an item, it generalizes better due to the denser feature rating data, it explains the prediction of item ratings …

Alternative Investment Markets Under Criticism: Reasons To Be Worried? Lessons From Gowex, Aurelio Gurrea-Martinez

Research Collection Yong Pung How School Of Law

The recent financial scandal of Gowex in the Spanish Alternative Investment Market (MAB) has reopened the debate about the dangers of lightly regulated markets and their optimal level of regulation. This article argues that Gowex’s collapse was not a failure of these markets but a failure of the gatekeepers in charge of overseeing Gowex’s activities. Therefore, we propose that regulators should focus on providing mechanisms to encourage gatekeepers to do their work in an effective and credible way. Namely, we propose that regulators should enhance the role and effectiveness of Nominated Advisers, since these players have been created precisely for …

Research outputs 2014 to 2021

The stability of post-traumatic growth overtime and the relationship between post-traumatic growth and traditional distress outcomes remains unclear. We tracked post-traumatic growth in a population-based sample of colorectal cancer patients from soon after diagnosis to five years subsequently to assess the heterogeneity of a post-traumatic growth response to cancer over time and describe the simultaneous and longitudinal relationships between post-traumatic growth and psychological distress. 1966 colorectal patients who were five months post diagnosis were assessed six times over a five year period. There was considerable heterogeneity associated with both psychological distress and benefit finding scores over time. However, both for …

Failure Of Science, Death Of Nature, H.F. Recher

Research outputs 2014 to 2021

As a people, Australians have lost contact with the world of nature, Risking the collapse of civilization. One factor in the alienation of nature in Australia is the failure of the scientific community to take responsibility for the technology created by the knowledge generated from scientific research. Science has failed to protect Australia's flora and fauna. Scientists must communicate more widely with society, but need to be educated on how to communicate and on their ethical responsibilities to others and other species. Government needs to show leadership in environmental management and nature conservation, while conservationists need to 'invert the paradigm', …
