Spatial and temporal variation in the breeding of Masked Lapwings (Vanellus miles) in Australia

Spatial and temporal variation in the breeding of Masked Lapwings (Vanellus miles) in Australia were examined using data from Birds Australia’s Nest Record Scheme (NRS; 1957–2002), the Atlas of Australian Birds (1998–2006), and climatic data (1952–2006). Breeding in north-western Australia was concentrated in summer, while in other regions the peak of breeding occurred during spring. Breeding success varied between regions and years but was generally highest in Tasmania. Clutch-size (mean 3.57 eggs ± 0.033 s.e., n = 549 clutches) did not vary regionally or temporally. In the north-east, breeding became earlier over time (~1.9 days per year, NRS), while in the south-east, breeding became later (~0.9 days per year); in other regions temporal trends were not evident. Only Tasmania showed a significant temporal change in breeding success (decrease of ~1.5% per year). All regions experienced warming climates, and annual rainfall increased in north-western regions and decreased in eastern regions. There were weak or no relationships between the amount or success of breeding, clutch-size and the climatic variables considered (with the possible exception of Tasmania), suggesting either that data limitations precluded us from detecting subtle effects or that Masked Lapwings have been little influenced or are resilient to changes in climate over most of their range.

Terrestrial detritus supports the food webs in lowland intermittent streams of south-eastern Australia : a stable isotope study

1. Large amounts of terrestrial detritus enter many low-order forested streams, and this organic
material is often the major basal resource in the metazoan food webs of such systems. However,
despite their apparently low biomass, algae are the dominant food of organisms in a number of
aquatic communities which conventionally would have been presumed to be dependent on
allochthonous detritus, particularly those in the tropics and also in lowland intermittent streams
in arid Australia.
2. The dual stable isotope signatures (d13C and d15N) of potential primary food sources were
compared with the isotopic signatures of common aquatic animals in lowland intermittent
streams in south-eastern Australia, in both spring and summer, to determine whether
allochthonous detritus was an important nutritional resource in these systems. The isotopic
signatures of the major potential allochthonous plant food sources (Eucalyptus, Phalaris and
Juncus) overlapped, but were distinct from algae and the dominant macrophytes growing in the
study reaches. The isotopic signatures of biofilm were more spatially and temporally variable
than those of the other basal resources.
3. Despite allochthonous detritus having relatively high C : N ratios compared to other
potential basal resources, results from ISOSOURCE mixing model calculations demonstrated
that this detritus, and the associated biofilm, were the major energy sources assimilated by
macroinvertebrate primary consumers in both spring and summer. The importance of these
energy sources was also reflected in animals higher in the food web, including predatory
macroinvertebrates and fish. These resources were supplemented by autochthonous sources of
higher nutritional value (i.e. filamentous algae and macrophytes, which had relatively low
C : N ratios) when they became more prolific as the streams dried to disconnected pools in
summer.
4. The results highlight the importance of allochthonous detritus (particularly from Eucalyptus)
as a dependable energy source for benthic macroinvertebrates and fish in lowland intermittent
streams of south-eastern Australia. This contrasts with previous stable isotope studies
conducted in lowland intermittent streams in arid Australia, which have reported that the fauna
are primarily dependent on autochthonous algae.

Habitat requirements of the yellow-footed antechinus (Antechinus flavipes) in box–ironbark forest, Victoria, Australia

Understanding the habitat requirements of a species is critical for effective conservation-based management. In this study, we investigated the influence of forest structure on the distribution of the yellow-footed antechinus (Antechinus flavipes), a small dasyurid marsupial characteristic of dry forests on the inland side of the Great Dividing Range, Australia. Hair-sampling tubes were used to determine the occurrence of A. flavipes at 60 sites stratified across one of the largest remaining tracts of dry box–ironbark forest in south-eastern Australia. We considered the role of six potential explanatory variables: large trees, hollow-bearing trees, coppice hollows, logs, rock cover and litter. Logistic regression models were examined using an information-theoretic approach to determine the variables that best explained the presence or absence of the species. Hierarchical partitioning was employed to further explore relationships between occurrence of A. flavipes and explanatory variables. Forest structure accounted for a substantial proportion of the variation in occurrence of A. flavipes between sites. The strongest influence on the presence of A. flavipes was the cover of litter at survey sites. The density of hollow-bearing trees and rock cover were also positive influences. The conservation of A. flavipes will be enhanced by retention of habitat components that ensure a structurally complex environment in box–ironbark forests. This will also benefit the conservation of several threatened species in this dry forest ecosystem.

Building research capacity in General Practice : Incorporating research as a component of GP vocational training

Aims & rationale/Objectives : Australian research shows that most GP registrar supervisors lack confidence to support registrar research projects and themselves have little or no research experience. Assisting registrars to develop critical thinking skills and an understanding of research methods sufficient to enable active use of these tools in general practice is one of the curriculum statements in the RACGP Training Program Curriculum. A University Department of Rural Health (UDRH) and a General Practice Education and Training (GPET) organisation formed a partnership to: Engage basic term registrars in group research and concurrent research skills training program; Improve research skills, confidence, and knowledge; and Contribute research findings relevant to general practice.

Methods : Registrars' initial research knowledge and confidence was measured by a questionnaire. In addition to a final focus group, feedback via evaluation forms was sought from the 11 registrars and two GPET supervisors at the conclusion of each research training session.

Principal findings : Approaches

Implications : Research skills development training and involvement in research can be successfully integrated into a GP vocational training program.

Hair braiding : working the boundaries of methodology in globalisation research

This paper engages the constitutive as well as the representative role of metaphor in research. Metaphors are understood to provide possibilities for representations and conceptualisations. The use of metaphorical redescription permits us to 'use familiar words in unfamiliar ways' (Rorty, 1989, p. 18) and provides new language that deters the use of repeated ways of knowing. It invites us to see things differently and to act differently. Lakoff and Johnson (1980) argue that metaphor does more than represent: 'New metaphors have the power to construct a new reality' (p. 145). I have drawn on both these understandings of metaphor. In qualitative research, metaphorical analysis has a well-established history. Researchers analyse metaphors used by research participants and apply metaphors to participant actions and understandings (Koro-Ljungberg, 2001; Gregory & Noblit, 1998). Researchers also use metaphors to reflect or represent their methodological decision-making (Richardson, 2003; Gadamer, 1989). In this article, I have nudged the conceptual boundaries of methodology. I have argued the constructive nature of metaphor in methodological positioning and decision making. I use the writing of a doctoral thesis to argue this role of metaphor. There, the metaphor of hair braiding constructed and communicated my methodological decision-making and my researcher stance as a braider.

Critical analysis of action research-based inservice teacher education : four case histories

Changing the nature of institutionalised education is the central theme of the thesis. The potential for radical changes to classroom teaching and to inservice teacher education is considered through four curriculum and teaching reform projects structured by action -research. The problems explored through the thesis are at the levels of teaching, institutional and research practices. It is argued that the professional activity of teachers, administrators, consultants, teacher educators and researchers can be understood to be tightly bound and determined by rules for acceptable professional ways of acting which are often unquestioned and unexamined by educators themselves. It is further argued that institutionalised education is dominated by ways of thinking and acting that are inherently individualistic. The thesis analyses the ideological character of this 'individualistic1 structuring of educational practice, identifying belief systems that hold the lived reality of educators and students in place. The thesis endeavours to show that the bureaucratic character of institutionalised education primarily serves and maintains the interests of dominant groups. The thesis examines the possibilities for radical reform in classroom teaching, the support teachers need when embarking on curriculum and teaching change processes, and the possible outcomes of such reform. The thesis also examines the interaction between the institutional practices of schools, universities and regional offices in the Ministry of Education in Victoria, Australia on these reform processes in classrooms. Finally, the thesis examines the potential of action research as a research and educative process in the professional development of educators who are both critically aware of the ideological nature of institutionalised education and committed to collective social action. From the analyses of the four action research projects the thesis concludes that action research has the potential to transform institutionalised education when its own practice is firstly, developed as a liberating pedagogy and not as research projects structured by individualistic and paternalistic interests; secondly, is driven by a commitment to the political struggle for equity and social justice; and thirdly, is itself an expression of communitarian work. The thesis concludes that the transformative processes associated with action research under these conditions hold the promise of democratising the 'individualistic' character of institutional education.

Ecological value of riparian zones to birds in forest landscapes

Riparian zones are a characteristic component of many landscapes throughout the world and increasingly are valued as key areas for biodiversity conservation. Their importance for bird communities has been well recognised in semi-arid environments and in modified landscapes where there is a marked contrast between riparian and adjacent non-riparian vegetation. The value of riparian zones in largely intact landscapes with continuous vegetation cover is less well understood. This research examined the importance of riparian habitats for avifauna conservation by investigating the ecological interactions contributing to the pattern of bird assemblages in riparian and adjacent non-riparian habitats. Specifically, the focus is on the bird assemblages of riparian zones and those of adjacent non-riparian vegetation types and the influence that associated differences in resource availabilities, habitat structure and conditions have on observed patterns. This study was conducted in the foothill forests of the Victorian Highlands, south-east Australia. Mixed-species eucalypt (genus Eucalyptus) forests dominate the vegetation of this region. Site selection was based on the occurrence of suitable riparian habitat interspersed within extensive, relatively undisturbed (i.e. no recent timber harvesting or fire events) forest mosaics. A series of 30 paired riparian and non-riparian sites were established among six stream systems in three forest areas (Bunyip State Park, Kinglake National Park and Marysville State Forest). Riparian sites were positioned alongside the stream and the non-riparian partner site was positioned on a facing slope at a distance of approximately 750 m. Bird surveys were carried out during 29 visits to each site between July 2001 and December 2002. Riparian sites were floristically distinct from non-riparian sites and had a more complex vegetation structure, including a mid-storey tree layer mostly absent from non-riparian sites, extensive fine litter and coarse woody debris, and dense ground-layer vegetation (e.g. sedges and ground ferns). The characteristic features of non-riparian habitats included a relatively dense canopy cover, a ground layer dominated by grasses and fine litter, and a high density of canopy-forming trees in the smaller size-classes. Riparian zones supported a significantly greater species richness, abundance and diversity of birds when compared to non-riparian habitats. The composition of bird assemblages differed significantly between riparian and non-riparian habitats, with riparian assemblages displaying a higher level of similarity among sites. The strongest contributors to observed dissimilarities between habitat types included species that occurred exclusively in either habitat type or species with large contrasts in abundance between habitat types. Much of the avifauna (36%) of the study area is composed of species that are common and widespread in south-east Australia (i.e. forest generalists). Riparian habitats were characterised by a suite of species more typical of wetter forest types in south-east Australia and many of these species had a restricted distribution in the forest mosaic. Some species (7%) occurred exclusively in riparian habitats (i.e. riparian selective species) while others (43%) were strongly linked to these habitats (i.e. riparian associated species). A smaller proportion of species occurred exclusively (2%) in non-riparian habitats (i.e. non-riparian selective species) or were strongly linked to these habitats (10%; i.e. non-riparian associated species). To examine the seasonal dynamics of assemblages, the variation through time in species richness, abundance and composition was compared between riparian and non-riparian sites. Riparian assemblages supported greater richness and abundance, and displayed less variation in these parameters, than non-riparian assemblages at all times. The species composition of riparian assemblages was distinct from non-riparian assemblages throughout the annual cycle. An influx of seasonal migrants elevated species richness and abundance in the forest landscape during spring and summer. The large-scale movement pattern (e.g. coastal migrant, inland migrant) adopted by migrating species was associated with their preference for riparian or non-riparian habitats in the landscape. Species which migrate north-south along the east coast of mainland Australia (i.e. coastal migrants) used riparian zones disproportionately; eight of eleven species were riparian associated species. Species which migrate north-south through inland Australia (i.e. inland migrants) were mostly associated with non-riparian habitats. The significant differences in the dynamics of community structure between riparian and non-riparian assemblages shows that there is a disproportionate use of riparian zones across the landscape and that they provide higher quality habitat for birds throughout the annual cycle. To examine the ecological mechanisms by which riparian assemblages are richer and support more individual birds, the number of ecological groups (foraging, nest-type and body mass groups) represented, and the species richness of these groups, was compared between riparian and non-riparian assemblages. The structurally complex vegetation and distinctive habitat features (e.g. aquatic environments, damp sheltered litter) provided in the riparian zone, resulted in the consistent addition of ecological groups to riparian assemblages (e.g. sheltered ground – invertebrates foraging group) compared with non-riparian assemblages. Greater species richness was accommodated in most foraging, nest-type and body mass groups in riparian than non-riparian assemblages. Riparian zones facilitated greater richness within ecological groups by providing conditions (i.e. more types of resources and greater abundance of resources) that promoted ecological segregation between ecologically similar species. For a set of commonly observed species, significant differences in their use of structural features, substrates and heights were registered between riparian and non-riparian habitats. The availability and dynamics of resources in riparian and non-riparian habitats were examined to determine if there is differential availability of particular resources, or in their temporal availability, throughout the annual cycle. Riparian zones supported more abundant and temporally reliable eucalypt flowering (i.e. nectar) than non-riparian habitats throughout the annual cycle. Riparian zones also supported an extensive loose bark resource (an important microhabitat for invertebrates) including more peeling bark and hanging bark throughout the year than at non-riparian sites. The productivity of eucalypts differed between habitat types, being higher in riparian zones at most times for all eucalypts combined, and for some species (e.g. Narrow-leaved Peppermint Eucalyptus radiata). Non-riparian habitats provided an abundant nectar resource (i.e. shrub flowering) at particular periods in the annual cycle. Birds showed clear relationships with the availability of specific food (i.e. nectar) and foraging resources (i.e. loose bark). The demonstration of a greater abundance of resources and higher primary productivity in riparian zones is consistent with the hypothesis that these linear strips that occupy only a small proportion of the landscape have a disproportionately high value for birds. Riparian zones in continuous eucalypt forest provide high quality habitats that contribute to the diversity of habitats and resources available to birds in the forest mosaic, with positive benefits for the landscape-level species pool. Despite riparian and non-riparian habitat supporting distinct assemblages of birds, strong linkages are maintained along the riparian-upslope gradient. Clearly, the maintenance of diverse and sustainable assemblages of birds in forest landscapes depends on complementary management of both riparian and non-riparian vegetation.

Lay healing practices in the household

This thesis explores the power-knowledge relationship underlying lay healing practices in the household; a non-traditional area of study in public health. Lay knowledge continues to be discounted as illegitimate and !non-expert' by policymakers, health professionals and academics. Given the absence of theory on lay knowledge and decision-making, an eclectic theoretical approach was undertaken in this study. Theory is drawn from medical anthropology, sociology of the body, health economics, gender studies, social theory, psychology, nursing, ethics, philosophy and history of medicine in order to contribute to and advance debate. Operating within the genre of a 'multi-sited ethnography' (working across different sites), methods for data collection included 'anthropology at home' by undertaking fieldwork in Geelong, Victoria, Australia. I conducted interviews and focus group discussions with, and administered a questionnaire to, 98 participants who are parents of young children. They were recruited via primary schools and snowball sampling. The quantitative data presents a socio-demographic 'picture' of 78 women and 20 men (representing 98 households) from urban, rural and coastal areas of the region. The qualitative data contains case studies as well as narratives, analysed for their content and discourses. Additional methods included maintenance of a 'reflexive journal', inter-sectoral consultations and public health policy analysis. Research findings indicate laypeople's conceptualisations of the body, self, health and illness rest upon a notion of the embodied self and health that is physical, mental and spiritual. Lay people have a substantial knowledge base on health and ill-health that derives from many sources, is both generalised and specialised, and is set within the context of everyday life. Laypeople make diagnoses and treat illness and injury within the household. They also exercise substantial agency in determining their choice of healer(s) for therapeutic intervention and management of ill-health outside the household. This study has substantial implications for public health in terms of healers' clinical practices, research and policy.

Australia and Japan in the South Pacific island countries : a general appraisal through the concepts of structural power

This study examines several specific fields of activity of Australia and Japan in the areas of security, production, finance, development assistance, information, education and regional organization. Using the concept of structural power, it observes the sources of Australian and Japanese strenght in the region, the growing imbalance in the bilateral Australia-Japan relationship, and also the coexistence of affinities and differences in the development opportunities opened to the South Pacific Island Countries.

Illness representations and cancer screening in older women

This research investigated why some older women do not obtain screening mammograms and Pap smear tests. In-depth interviews found many beliefs which are contrary to screening and influenced the women's screening behaviour.

Crossbreeding generated viable progeny and differences were found between strains in reproductive performance, sex ratios, morphology and overall genetic divergence measured by DNA sequencing.

Revolt and discovery : towards an understanding of practice as research through Kristevan aesthetics

This paper will examine Kristeva’s conceptions of revolution and revolt to demonstrate the significance of her work for practitioners and researchers working in the emerging field of creative arts practice as research, a field of research that is burgeoning in the UK, Australia, Canada and Scandinavia. I will argue that Kristeva’ thought elaborates the aesthetic underpinnings of discovery and provides a rationale for the methodologies used in artistic research.

In her later work on interpretation, Kristeva places a greater emphasis on the need for analysis or theory, since the art and culture of revolt produce unfamiliar or mutant meanings that are difficult for audiences to grasp in terms of their potency for engendering social change and individual empowerment. However, she places the responsibility for this analysis and interpretation on the art critic. But what if (as is the case with the advent of artistic practice as research), the maker and the “critic” become one and the same? Can this shift in the status of artistic practice within the knowledge economy, be understood in terms of Kristeva account of the sense and nonsense of revolt? I will address these questions by revisiting aspects of Kristeva thinking on experience-in practice and examining her more recent and extended elaboration of revolutionary practice. The paper will explore how her thinking can provide practitioners with a framework for understanding creative arts research as the production of new knowledge. If as Kristeva argues, that art and literature are amongst the few means of revolt and renewal, it seems appropriate to turn to her thinking in order to articulate a rationale and argument for claiming that practice as research can operate as a driver of change and innovation in contemporary culture.

The first part of this task will involve tracing what Kristeva sees as three forms of revolt made possible through aesthetic experience. This will involve a closer examination of the notions of transgression and art as experience. Following on from this discussion, I will discuss how Kristeva’s work constitutes both an implicit and explicit critique of science allowing us to conceive of artistic research as an alternative and performative production of knowledge. Finally in this paper, I will apply and illustrate these ideas through an analysis of a selection of a number of research projects successfully completed by artistic researchers in Australia. I hope to show that artistic practice as a mode of enquiry, reveals the inextricable and necessary relationship between practice and theory, interpretation and making, art and life. I suggest that it is this interrelationship, that underpins what Kristeva describes as creative and revolutionary practice. In the context of creative arts practice as research, Kriteva’s account of experience–in-practice indicates that interpretation and analysis must fall to the practitioner-researcher himself or herself - rather than to another person who has been external to the procedures of making - to trace the significant experiential, subjective and emergent processes involved in the production of the work that allows it to reveal the new. This is necessary if the generative and revolutionary impact of artistic research is to be fully understood in the wider research arena.

A critical analysis of central bank independence and governance in Australia and Bangladesh

This study examines central bank independence and governance (CBIG) in Bangladesh and Australia. It applies a unique index model of Ahsan, Skully and Wickramanayake (2008) to assess their respective legal, political, price stability objectives, exchange rate policies, monetary policy and deficit financing practices, transparency and accountability positions from 1991 to 2008. While the model shows CBIG is much weaker in Bangladesh than in Australia, the Bangladesh Bank’s CBIG shown considerable improvement over the period. These findings suggest that the Government of Bangladesh might learn from Australia’s experience with Reserve Bank of Australia and delegate further power and authority to Bangladesh Bank as well as lessen its political interference.

Using constructed-response and multiple-choice questions in undergraduate examinations

This paper looks at the use of constructed-response and multiple-choice questions in first year management examinations involving 2364 students over a three semester period in 2008-9. It also compares student’s performance in research and analytical assignments with their results in Multiple-Choice tests. The results show that students who perform poorly in non-multiple-choice tests are slightly advantaged by multiple-choice tests. However, students who display high distinction scores in other pieces of assessment do not receive any advantage from multiple-choice testing. Interestingly, the research also highlighted that female students perform better in their articulation of management techniques overall, but do not gain the same comparative advantage from multiple choice testing. The analysis of the assessment methods was extremely useful in predicting the level of failures for the unit in the subsequent year. Finding the right balance of assessment tasks in first year university business courses is extremely difficult, using multiple-choice tests can be useful tool as part of the assessment mix in management units.

New Zealand and its competitors in the knowledge economy

In the US, Australia, the United Kingdom, Canada, Finland, Ireland and other countries, the growth of the Internet and other related new technologies have become the catalyst for the creation of ‘knowledge economies’. The new information and communication technologies have created global markets for goods and services. Countries that have encouraged their people through education and life-long learning and by investing heavily in research and development (R&D) are well positioned to take advantage of these new global markets. Along with globalisation has come the death of distance. Thanks to the Internet, New Zealand is no longer remote from the rest of the world.

But New Zealand’s economy is still too dependent on producing commodities for export. While efforts over the last fifteen years to diversify markets have been very successful, we still need to expand our limited range of products. We must take the next important step and transform New Zealand from a pastoral economy into a knowledge-driven economy. For New Zealand, the Internet is the modern equivalent of the freezer ship that revolutionised our economy last century. If New Zealanders do not seize the opportunities provided by the knowledge economy, we will survive only as an amusement park and holiday land for the citizens of more successful developed economies.

This article puts New Zealand into world perspective by assessing its knowledge economy benchmarks against its competitors. It outlines the theoretical background to ‘‘new growth theory'' and delineates the lessons of that theory, especially for New Zealand. It treats the key issues for New Zealand’s emergence as a knowledge economy, including education, the M ori dimension, immigration, research and development, venture capital, export policy and telecommunications regulation.
