Individual differences in affective responses to violence and sexual violence

The thesis aimed to identify and compare individual differences in anger related affective responses upon exposure to neutral, violent and sexually violent film. The findings revealed that both graphic and non-graphic sexually violent film content may have a stronger impact on viewers' anger levels than exposure to standard violent film. The portfolio examined in four case studies the utility of the Violence Risk Scale when seeking to identify factors associated with risk of violent recidivism and subsequent treatment targets for intellectually disabled offenders . Treatment indications must consider the impaired cognitive and adaptive abilities and the difficulties inherent in modifying the behavioural characteristics of intellectually disabled offenders.

Glycogen-protein associations in human skeletal muscle

The collective findings of this dissertation demonstrated little effect of exercise on the absolute or relative expression of glycogen regulatory proteins associated with a glycogen enriched fraction in human skeletal muscle. However the findings of this thesis help inform methodological approaches to future investigations into glycogen-protein associations.

Body image among Chinese-Australian and European-Australian men

Little is known about the body image concerns of non-European men living in Australia. In this research, Chinese-Australians demonstrated an "holistic" body image that included body shape, height, clothing and hairstyling concerns. Contrastingly, European-Australians separated muscularity concerns from general appearance considerations. Chinese-Australians utilised both Asian and Western internalisation/appearance comparison targets. The portfolio aims to critically evaluate the clinical utility of Evidence Based Practice (EBP). Four case studies analyse the practical advantages and disadvantages of EBP.

Dialectical behavior therapy in community mental health settings : an evaluation

Borderline personality disorder causes extreme and enduring suffering. Dialectical Behavior Therapy is a psychological intervention that has been developed to treat the disorder. Two studies were conducted to test the effectiveness of the treatment. Results showed that borderline personality disorder can be treated effectively in the public mental health system. The portfolio presents four case studies to examine the notion that Cognitive Behavior Therapy (CBT) is efficacious in the treatment of anxiety as a comorbid condition.

Being a palliative care volunteer

In this research volunteers' experiences in the field of palliative care were explored from the perspective of volunteers. The study made visible the skills, values and wisdom inherent in enactment of the volunteer role and provided new insights into the nature of relatedness between clients / families and volunteers.

Outcome after traumatic injury

The thesis' aim was to explore outcome after traumatic injury. Poorer physical health prior to injury and receipt of compensation explained variance in physical health 12 months after injury. Poorer mental health 3 and 12 months after injury was partly explained by stronger emotional reactions immediately after the injury, receipt of compensation, and lower perceived social support. The portfolio focuses on symptoms of depression and anxiety in those suffering chronic pain. Through four case studies who attended a pain management service, it is argued that psychological symptoms are able to be addressed concurrently with pain management strategies.

Factors facilitating successful engagement among patients with first-episode psychosis

This thesis investigated factors that facilitate successful engagement with psychiatric treatment among young patients experiencing first-onset psychosis. The results revealed the importance of the treatment setting and key relationships in achieving engagement. Service delivery implications include the need for a social relationship model between clinicians, patients, and their peers.

Students' perceptions of the value of the elements of an online learning environment : an investigation of discipline differences

This paper presents a large scale, quantitative investigation of the impact of discipline differences on the student experience of using an online learning environment (OLE). Based on a representative sample of 2526 respondents, a number of significant differences in the mean rating by broad discipline area of the importance of, and satisfaction with, a range of elements of an OLE were found. Broadly speaking, the Arts and Science and Technology discipline areas reported the lowest importance and satisfaction ratings for the OLE, while the Health and Behavioural Sciences area was the most satisfied with the OLE. A number of specific, systematic discipline differences are reported and discussed. Compared to the observed significant differences in mean importance ratings, there were fewer significant differences in mean satisfaction ratings, and those that were observed were less systematic than for importance ratings.

The association between physical activity and depression among young women

Young women experiencing depressive symptoms were shown to have different constraints to being active compared to young women without depressive symptoms, such as lower motivation and lower confidence in their ability to be active. Physical activity promotion initiatives may benefit from individually-tailored, multi-component programs rather than a 'one-fits-all', single-arm approach

Docosapentaenoic acid : its metabolism and effect on lipogenic gene expression

This thesis found that the omega-3 fatty acid, docosapentaenoic acid (DPA) down-regulates the expression levels of key lipogenic genes and proteins in vitro. In vivo studies with labelled DPA showed that, like docosahexaenoic acid, DPA is more conserved from oxidation compared with eicosapentaenoic acid.

Managing constipation in older people

The study consists of two parts: a systematic review that critically analysed existing Chinese medicine clinical trials in managing constipation and, a cluster randomised controlled trial investigating the effects of education and acupressure on constipation in older people. Participants in the experimental group reported significant improvements in their constipation symptoms.

Describing and understanding physical activity in desk-based work settings

This thesis investigated the physical activity behaviours of employees who commonly sit for work tasks. Specifically, this PhD explored the key influences on light-intensity physical activity during work hours and issues associated with subjectively assessing this behaviour. Overall, this PhD provided insights into a novel approach to address the important public health issue of physical inactivity.

Religiosity and subjective wellbeing in Christianity, Buddhism and Taoism

The relationship between three religions (Christianity, Buddhism and Taoism) and subjective wellbeing were studied. Religiosity and spirituality-religion satisfaction were significant predictors of subjective wellbeing. A new construct of religious self-esteem and a new scale of Christianity secondary control were found as useful in explaining subjective wellbeing.

Molting and reproduction in portunus pelagicus

This investigation describes ovarian maturation stages in the female reproductive system, evidence for histones in sperm nuclei and novel morphological changes that occur during spermiogenesis in the male blue swimming crab, portunus pelagicus. It also identifies dual functionality of the molt inhibiting hromone on molting and vitellogenesis through RNA inteference.

Psychological profiling of Tasmanian police officers using the COPS

This thesis examined selection processes for police candidates, and the impact of police work on well-being. Results revealed that policing impacts negatively on psychological well-being over time, and that many aspects of the stereotypic 'police personality' are not a result of selection processes, but develop over time in the role.
