Identifying the African wintering grounds of hybrid flycatchers using a multi-isotope (δ2H, δ13C, δ15N) assignment approach

Migratory routes and wintering grounds can have important fitness consequences, which can lead to divergent selection on populations or taxa differing in their migratory itinerary. Collared (Ficedula albicollis) and pied (F. hypoleuca) flycatchers breeding in Europe and wintering in different sub-Saharan regions have distinct migratory routes on the eastern and western sides of the Sahara desert, respectively. In an earlier paper, we showed that hybrids of the two species did not incur reduced winter survival, which would be expected if their migration strategy had been a mix of the parent species' strategies potentially resulting in an intermediate route crossing the Sahara desert to different wintering grounds. Previously, we compared isotope ratios and found no significant difference in stable-nitrogen isotope ratios (δ15N) in winter-grown feathers between the parental species and hybrids, but stable-carbon isotope ratios (δ13C) in hybrids significantly clustered only with those of pied flycatchers. We followed up on these findings and additionally analyzed the same feathers for stable-hydrogen isotope ratios (δ2H) and conducted spatially explicit multi-isotope assignment analyses. The assignment results overlapped with presumed wintering ranges of the two species, highlighting the efficacy of the method. In contrast to earlier findings, hybrids clustered with both parental species, though most strongly with pied flycatcher.

Service providers' experiences and needs in working with refugees in the Geelong region: a qualitative study

Service providers in Geelong, one of the priority locations for the resettlement of refugees in regional Australia, were interviewed to explore their perceptions of the health and wellbeing needs of refugees, and the capacity of service providers in a regional area to meet these. In all, 22 interviews were conducted with health and human service professionals in a range of organisations offering refugee-specific services, culturally and linguistically diverse (CALD) services in general, and services to the wider community, including refugees. The findings revealed that a more coordinated approach would increase the effectiveness of existing services; however, the various needs of refugees were more than could be met by organisations in the region at current resource levels. More staff and interpreting services were required, as well as professional development for staff who have had limited experience in working with refugees. It should not be assumed that service needs for refugees resettled in regional Australia will be the same as those of refugees resettled in capital cities. Some services provided in Melbourne were not available in Geelong, and there were services not currently provided to refugees that may be critical in facilitating resettlement in regional and rural Australia.

Don't eat that, you'll get fat! Exploring how parents and children conceptualise and frame messages about the causes and consequences of obesity

Family interactions about weight and health take place against the backdrop of the wider social discourse relating to the obesity epidemic. Parents (and children) negotiate complex and often contradictory messages in constructing a set of beliefs and practices around obesity and weight management. Despite this, very little research attention has been given to the nature of family-unit discourse on the subject of body weight and it's potential influence on the weight-related behaviours of family members. This includes the broad influence that dominant socio-cultural discourses have on family conceptualisations of weight and health. Using in-depth qualitative interviews with 150 family 'groups' comprised of at least one parent and one child in Victoria and South Australia, we explored how parents and children conceptualise and discuss issues of weight- and health-related lifestyle behaviours. Data were analysed using Attride-Stirling's (2001) thematic network approach. Three thematic clusters emerged from the analysis. First, both parents and children perceived that weight was the primary indicator of health. However, parents focused on the negative physical implications of overweight while children focused on the negative social implications. Second, weight and lifestyle choices were highly moralised. Parents saw it as their responsibility to communicate to children the 'dangers' of fatness. Children reported that parents typically used negatively-framed messages and scare tactics rather than positively-framed messages to encourage healthy behaviours. Third was the perception among parents and children that if you were thin, then eating habits and exercise were less important, and that activity could provide an antidote to food choices. Results suggest that both parents and children are internalising messages relating to obesity and weight management that focus on personal responsibility and blame attribution. These views reflect the broader societal discourse, and their consolidation at the family level is likely to increase their potency and make them resistant to change.

Student knowledge: curriculum, assessment and reporting

At a time when national and international high-stakes testing has assumed such prominence, one might begin to wonder about the status of teacher judgement when assessing and reporting on children’s knowledge and skills against the descriptors specified in curriculum standards. Were standardised test results congruent with the judgements that teachers make when reporting on students’ achievement, concern about how one type of judgement might compare with another would perhaps be unwarranted. This article draws on research that has investigated whether standardised assessments in the state of Victoria, Australia are actually comparable with teacher’s judgements about their students’ work to illustrate that discrepancies do exist. These results have been interpreted within an analytical framework that derives from Aristotle’s (350BC/2000) distinction between three types of knowledge, namely epistemic, technical and phronetic knowledge.

Resolving the value of the dingo in ecological restoration

There is global interest in restoring populations of apex predators, both to conserve them and to harness their ecological services. In Australia, reintroduction of dingoes (Canis dingo) has been proposed to help restore degraded rangelands. This proposal is based on theories and the results of studies suggesting that dingoes can suppress populations of prey (especially medium- and large-sized herbivores) and invasive predators such as red foxes (Vulpes vulpes) and feral cats (Felis catus) that prey on threatened native species. However, the idea of dingo reintroduction has met opposition, especially from scientists who query the dingo's positive effects for some species or in some environments. Here, we ask 'what is a feasible experimental design for assessing the role of dingoes in ecological restoration?' We outline and propose a dingo reintroduction experiment-one that draws upon the existing dingo-proof fence-and identify an area suitable for this (Sturt National Park, western New South Wales). Although challenging, this initiative would test whether dingoes can help restore Australia's rangeland biodiversity, and potentially provide proof-of-concept for apex predator reintroductions globally.

Program outcomes in youth justice outcomes: the PLUS+ program review

This report provides a methodology to assess the outcomes of rehabilitation programs that are delivered to young offenders in South Australia. A method of assessing change is described that can be applied across a number of different programs, but is illustrated in relation to one particular program, the PLUS+ program. PLUS+ is a group-based cognitive skills program which employs cognitive-behavioural methods of problem-solving, skills-training, and self-management to rehabilitate young offenders. It is one of the most intensive and best established programs to have been implemented in South Australia. Based on a review of this program a number of recommendations are made to enhance the future delivery and evaluation of PLUS+.
