This study examined the utility of a stress/coping model of antenatal depressive symptomatology. The direct and moderating effects of appraisal, coping resources and coping strategies on depression were explored. A total of 242 primiparous women completed questionnaires during the third trimester of pregnancy. Predictors included life events, coping resources (social support, quality of women's earlier relationships with parents), appraisal (threat, self-efficacy) and coping strategies (wishful thinking, positive reappraisal, problem solving, emotional approach). Results of regression analyses indicated that higher depression was related to higher stressful life events, threat appraisal and wishful thinking coping, and lower positive reappraisal coping. The expected stress exacerbation effects of wishful thinking on depression were supported. There was no support for the expected stress buffering effects of coping resources and coping strategies on depression. Findings provide preliminary support for the use of a stress/coping model to guide future research into psychosocial predictors of antenatal depression.
Historical ecology has revolutionized our understanding of fisheries and cultural landscapes, demonstrating the value of historical data for evaluating the past, present, and future of Earth’s ecosystems. Despite several important studies, Indigenous fisheries generally receive less attention from scholars and managers than the 17th–20th century capitalist commercial fisheries that decimated many keystone species, including oysters. We investigate Indigenous oyster harvest through time in North America and Australia, placing these data in the context of sea level histories and historical catch records. Indigenous oyster fisheries were pervasive across space and through time, persisting for 5000–10,000 years or more. Oysters were likely managed and sometimes “farmed,” and are woven into broader cultural, ritual, and social traditions. Effective stewardship of oyster reefs and other marine fisheries around the world must center Indigenous histories and include Indigenous community members to co-develop more inclusive, just, and successful strategies for restoration, harvest, and management.
This thesis is concerned with the relationship between Holocene environmental changes and human behaviour in coastal southeast Queensland. The study region covers an area stretching from Fraser Island in the north to the border of northern New South Wales in the south, and possesses the best documented and intensively scrutinised coastal archaeological record in Australia. The archaeology of the area was a major focus from the late 1970s when the Moreton Regional Archaeological Project, a long-term multi-stage regional project, was established to coordinate archaeological investigations in southeast Queensland. The Cooloola Region Archaeological Project was established in the mid-1980s to explore the archaeology north of the Noosa River. These initial studies provided the basis for a regional chronology, as well as models of settlement and subsistence based on the exploitation of the area's rich marine resources.In the time since the original work was conducted the research foci for coastal archaeology, both in Australia and internationally, have moved toward more complex issues such as assessing the impact of humans on marine ecosystems, the identification of patterns in resource exploitation strategies, and the use of molluscs as proxy evidence in local and regional environmental reconstructions.Additionally, regionally-specific models of Holocene environmental change have been developed, in line with greater emphasis being placed on the ecology and biology of the constituent species in middens in addressing questions of spatial and chronological variations in site patterning.In view of these developments, midden deposits from five sites from differing locations in southeast Queensland were re-analysed, and a literature review of two further sites was also undertaken, with the aim of assessing human behavioural variability during the mid to late Holocene through the Publications during candidature No publications Publications included in this thesis No publications included. vi Contributions by others to the thesisNo contributions by others.

The project has taken a long time to come to fruition, delayed by a combination of protracted and ultimately fruitless negotiations with stakeholders, illness, and bereavement. There are many people to thank for helping me to eventually get over the line. Chris was an undergraduate student in one of the University of Queensland Field Archaeology viii classes on Bribie Island in the early 1990s. Even then his knowledge of lithics was scary. Chris kindly stepped in as my principal advisor when Pat moved to Sydney. I must confess some disappointment that the artefact assemblages in my study were not more exciting for him but, as he does most things, he has calmly taken it in his stride.
<p>Although the sea arrived in southeast Queensland around 8000 years ago, most estuarine middens date to the past 1000 years. An example is midden deposits dating to the past 400 years forming the upper levels of Sites 62 and 75b from Tin Can Inlet located immediately south of the Fraser Island (K’gari) World Heritage Area. Both sites were excavated and analysed in the 1980s. This paper revisits these results following a detailed re-analysis of midden materials and new insights on regional sea level changes. Taking an historical ecology approach, species-specific habitat requirements and associated substrate sediment dynamics help explain similarities and differences between the two midden shell assemblages. Environmental factors and the location of both sites on landforms that formed following sea level fall over the past 2000 years help explain why the basal levels of both sites are probably <1000–1500 years old. Documenting pre-2000-year-old Aboriginal use of Tin Can Inlet will need to target more elevated inland dune deposits (>5m ASL) fronting the mid-Holocene sea level highstand palaeoshoreline.</p>
