Crisis of meanings : divergent experiences and perceptions of the marine environment in Victoria, Australia

The oceans of the world are regularly depicted as under threat from human exploitation with the problem portrayed as being of 'global' concern. In a world market characterised by the division of labour, many of those who eat fish do so without directly experiencing the ocean as a domain of productive utility. Rather, their encounters are with representations that depict the 'natural' world as an aesthetic object of contemplation, and environmentalist discourses that identify human activities as' threatening marine ecosystems. So prevalent is this experience that tangible institutions, such as state fisheries management bodies, have emerged, acting to reinforce the ontology of this 'contemplated' ocean, giving weight to the illusion that humans can, and should, appreciate it only from afar. In this representation, commercial fishers are regularly depicted as transgressing a 'natural' boundary between humans and the environment. It is when the world is simultaneously encountered as an object of consumptive utility and aesthetic utility that the human role in the environment becomes ambiguous and a sense of crisis arises. This paper investigates disjunctions in experiences and understandings that contribute to environmental anxiety, and debates over the appropriate use of the ocean.

Ecological response to environmental flows in two lowland rivers

Environmental disturbances in the Glenelg and Wimmera Rivers have been exacerbated by low flows. Consequently, environmental flows have been recommended although there is little empirical evidence of their effects. This thesis has shown that environmental flows are potentially beneficial in rivers subject to disturbances such as salinisation and sedimentation.

Sentencing pathways for offenders in Victoria : clinical influences and considerations

This portfolio aims to review aspects of the sentencing of violent offenders under Victoria's criminal justice system. Focuses on a critique of current legislation, the way the rights of special needs offenders are acknowledged and enshrined in law, how these provisions are expressed in practice, and the clinical factors that contribute to, and influence, the dispositions individuals receive.

Palaeontological aspects of the Permian Broughton Formation, Sydney Basin, Australia

An abundant, low diversity cool-water macroinvertebrate fauna from the Middle Permian Broughton Formation in the Sydney Basin, eastern Australia, was investigated. The fauna was described and identified, which assisted in regional and global correlation of the Broughton Formation, as well as palaeogeographical and palaeontological research.

Grouper aquaculture in three Asian countries : farming and economic aspects

The study focussed on three key suppliers of fingerlings and live fish in Asia. Grouper hatchery businesses are lucrative even at low survival rates. The findings indicate that farming practices across these countries are similar. Most farmers adopt traditional practices and lack incentives to reduce cost, but remain proce focussed.

The legal response to problem gambling in Victoria

The thesis analyses judgments from the higher criminal courts in Victoria involving problem gamblers charged with serious crimes, investigates actions brought by gamblers against gaming establishments in the civil courts and examines the legislation governing gambling in Victoria and the effectiveness of recently introduced harm minimisation measures.

Influence of disturbance on threatened fauna and associated habitat, Victoria

Results of fauna and vegetation surveys conducted around Portland Aluminium smelter between 1979 and 2004 found small mammal abundance and diversity had declined and changes in vegetation communities were related to changes in fire patterns, vegetation fragmentation and weed invasion. Small mammal numbers were greater in nearby National Parks.

Aspects of the life history of skates from southeastern Australia

The age and growth, reproduction and diet of several skate species in south-east Australia were studied. From studying these life history characteristics it was determined that skates have a relatively low productivity and may therefore be at risk of local extinction if increasingly exploited without appropriate management.

Literature and environmental ethics

This thesis contends that literature which reflects, and is informed by (whether consciously or not), reconstructive postmodern ecology is not a static literature but by representing and confronting the underpinning causes that have led humanity to violence, literature generates new engagements and the potential to reconstruct - ethically, cognitively, perceptually- alternative ways of being-in-the-world for political ends.

Health beliefs and behaviours of home economics teachers in Victoria

Data from questionnaires mailed to post-primary home economics teachers suggests that they possess untapped knowledge and expertise that could be used in intersectoral approaches to health promotion outside classroom teaching.

Invoice methodology

An innovative method for measuring the impact of an environmental food service intervention on the nutritional quality of the food supply was developed and implemented at five food services in Victoria as part of a Catering Improvement Program trial. This study used the invoice data to investigate changes in food supply at these food services.

Contextualising learning through the participatory construction of an environmental education programme

Strengthening links between school and community is critical for improving people's participation in environmental issues. However, Mexican education programmes are generally unrelated to rural students' life experience and are planned without considering either teachers' or students' opinions. This article describes the participatory construction of a preparatory school environmental education (EE) programme in Ixtlan de Juarez, a Mexican indigenous community internationally recognised for sustainable forest management. The qualitative research methods used are based on the action research methodology. Results from interviews conducted with the preparatory school's headmaster, the coordinator, and nine teachers provided the needed documentation of the school site for contextualising learning activities. Feedback during focus groups with six students, three teachers, five local communal authorities, and two researchers highlighted that all participants perceived the need for creating an educational programme focused on local forest management. The contents and activities of the programme were designed by the focus group's participants. The programme has been continuously taught by teachers and forest workers since 2005 and was officially integrated with the preparatory school science curriculum in 2006. This participative educational experience has thus transformed the mandatory school curriculum in Ixtlan.

Personal, social and environmental correlates of healthy weight status amongst mothers from socioeconomically disadvantaged neighborhoods : findings from the READI study

Background

Socioeconomically disadvantaged mothers are at high risk of obesity, yet the aetiology of obesity in this group remains poorly understood. The aim of this study was to examine the perceived personal, social and physical environmental factors associated with resilience to obesity among mothers from socioeconomically disadvantaged neighbourhoods.
Methods

Survey data were provided by a cohort of 1840 women aged 18-46 years with dependent children (aged 0-18 years) from 40 urban and 40 rural socioeconomically disadvantaged neighbourhoods across Victoria, Australia. Mothers responded to a number of questions relating to personal, social and environmental influences on their physical activity and eating habits. Mothers' weight status was classified as healthy weight (BMI: 18.5-24.99), overweight (BMI: 25-29.99) or obese (BMI: 30+).
Results

Mothers' weight status was bivariably associated with factors from all three domains (personal, social and physical environmental). In a multivariable model, mothers' perceived ability to make time for healthy eating (OR = 1.34) and physical activity (OR = 1.11) despite family commitments, and the frequency with which families ate healthy low-fat foods with mothers (OR = 1.28) remained significantly positively associated with healthy weight status. The frequency with which families encouraged eating healthy low-fat foods remained negatively associated (OR = 0.81) with weight status; ie greater encouragement was associated with less healthy weight status.
Conclusions

Drawing on the characteristics of mothers resilient to obesity might assist in developing intervention strategies to help other mothers in socioeconomically disadvantaged neighbourhoods to manage their weight. Such strategies might focus on planning for and prioritising time for healthy eating and physical activity behaviours, and including family members in and encouraging family mealtimes.
