Does migration of hybrids contribute to post-zygotic isolation in flycatchers?

In the face of hybridization, species integrity can only be maintained through post-zygotic isolating barriers (PIBs). PIBs need not only be intrinsic (i.e. hybrid inviability and sterility caused by developmental incompatibilities), but also can be extrinsic due to the hybrid's intermediate phenotype falling between the parental niches. For example, in migratory species, hybrid fitness might be reduced as a result of intermediate migration pathways and reaching suboptimal wintering grounds. Here, we test this idea by comparing the juvenile to adult survival probabilities as well as the wintering grounds of pied flycatchers (Ficedula hypoleuca), collared flycatchers (Ficedula albicollis) and their hybrids using stable isotope ratios of carbon (δ13C) and nitrogen (δ15N) in feathers developed at the wintering site. Our result supports earlier observations of largely segregated wintering grounds of the two parental species. The isotope signature of hybrids clustered with that of pied flycatchers. We argue that this pattern can explain the high annual survival of hybrid flycatchers. Hence, dominant expression of the traits of one of the parental species in hybrids may substantially reduce the ecological costs of hybridization.

State–Chaebol relations in the post-crisis period

This article examines contemporary Korean capitalism via an analysis of state-chaebol relations in the post-crisis period. The Korean state played a prominent role in industrial and financial restructuring after the crisis. Some scholars argue that a 'new' state has emerged in Korea, with the activism during the financial crisis representing only a temporary diversion from the shift towards a 'competition state'. Others claim that the Korean state still seeks to directly shape economic outcomes: some policy instruments have changed, but strategic intent, defined here as the will to directly manage investment flows and shape economic structures, has not. The transition of Korean capitalism from the developmental state system towards neo-liberalism, this article argues, is far from complete. Emphasizing the situated choices of state elites and the challenging political context in which they find themselves, we presume a condition of mutual dependence between the state and chaebols. Given incidences of conflict in the post-crisis context, we argue that the state has not fully reasserted its will over the chaebols. The restructuring of chaebols ('Big Deals') are best understood as symbolic measures intended to garner external support for the Korean state rather than unfettered exercise of strategic intent. At the same time, we go beyond existing accounts of 'state decline' by highlighting the place of economic performance by the chaebols as the preeminent criteria for state support. The state and chaebols remain central to Korean capitalism, even in its current hybrid and somewhat dysfunctional form.

Dual audiences, double pedagogies : representing family literacy as parental work in picture books

Narrative for a dual audience of children and adults is a field of expanding interest among children’s literature scholars. A great deal of the extant research is implicitly or explicitly informed by longstanding anxieties about the status of children’s fiction, a context that shifts the parameters of the analysis to questions of literary sophistication. Whilst some attention is paid to the readersubject position of the child reader, rather less is given to the positioning of the adult reader in relation to the pedagogical agendas of such texts. This article examines picture books featuring parents reading to preschool children. In the context of family literacy, it is an instance in which the pedagogical address to the adult reader is as significant as the address to the child. Drawing on distinctions between double and dual address, the article examines the ways in which representations of parents.

Post-war migrant built heritage in Melbourne : from assimilation to multiculturalism

If place identities are created by ascribing subjective meaning to sites and buildings it follows that diverse groups will consider place meaning differently. This poses a challenge for the selection and interpretation of heritage sites in plural societies where notions of architectural significance are likely to conflict. Basing heritage policy on the premise of a shared heritage is particularly challenging when the cultural traditions of the past underlie definitions of architectural significance in a more culturally diverse present. This paper presents an introduction to research exploring the inclusion of twentieth century migrant built heritage in Australia. Through selected examples of recently recognised heritage sites in Melbourne, the paper considers how migrant heritage is included and what this reveals about the cultural traditions underlying Australian heritage discourses. The inclusion of migrant places suggests that there is an initial shift in heritage discourses where notions of architectural significance have expanded to include the history of post-war migration. However, the examples raise questions about the nature of cultural inclusivity in heritage frameworks.

A pilot study of a telephone-based parental intervention to increase fruit and vegetable consumption in 3-5 year old children

Objective : To examine the potential efficacy of a brief telephone-based parental intervention in increasing fruit and vegetable consumption in children aged 3–5 years and to examine the feasibility of intervention delivery and acceptability to parents.

Design : A pre–post study design with no comparison group. Telephone surveys were conducted approximately 1 week before and following intervention delivery.
Setting Participants were recruited through pre-schools in the Hunter region, New South Wales, Australia.

Subjects : Thirty-four parents of 3–5-year-olds received four 30-min interventional telephone calls over 4 weeks administered by trained telephone interviewers. The scripted support calls focused on fruit and vegetable availability and accessibility within the home, parental role modelling of fruit and vegetable consumption and on implementing supportive family eating routines.

Results : Following the intervention, the frequency and variety of fruit and vegetable consumption increased (P = 0·027), as measured by a subscale of the children's dietary questionnaire. The intervention was feasible to be delivered to parents, as all participants who started the intervention completed all four calls, and all aspects of the interventional calls, including the number, length, content, format and relevance, were considered acceptable by more than 90 % of parents.

Conclusions : A brief telephone-based parental intervention to encourage fruit and vegetable consumption in pre-school-aged children may be effective, feasible and acceptable. Further investigation is warranted in a randomised controlled trial.

Post-colonial states, ethnic minorities and separatist conflicts : case studies from Southeast and South Asia

Post-colonial states in the Asian region have frequently been subject to political tensions derived from their multi-ethnic make-up and, what some have argued to be, the failure of states to adequately represent the interests of their ethnic minorities. This article will look at examples of where states in Asia have failed to adequately represent or otherwise incorporate their ethnic minorities as full and equal citizens. It also considers the range of responses to such perceived or actual state failure in adequately incorporating all citizens, including inter-ethnic and racial violence and separatist conflict. The article will conclude by considering conceptual and actual models of state organization intended to resolve racial and ethnic tensions in the Asian region.

Parental influences on adolescent fruit consumption : the role of adolescent self-efficacy

The aims of this study were to examine whether adolescent self-efficacy mediates the associations between parental control, perceptions of the importance of healthy nutrition for child health and barriers to buying fruits and vegetables and adolescent fruit consumption using a theoretically derived explanatory model. Data were drawn from a community-based sample of 1606 adolescents in Years 7 and 9 of secondary school and their parents, from Victoria, Australia. Adolescents completed a web-based survey assessing their fruit consumption and self-efficacy for increasing fruit consumption. Parents completed a survey delivered via mail assessing parental control, perceptions and barriers to buying fruit and vegetables. Adolescent self-efficacy for increasing fruit consumption mediated the positive associations between parental control and perceptions of the importance of healthy nutrition for child health and adolescent fruit consumption. Furthermore, adolescent self-efficacy mediated the negative association between parental barriers to buying fruits and vegetables and adolescent fruit consumption. The importance of explicating the mechanisms through which parental factors influence adolescent fruit consumption not only relates to the advancement of scientific knowledge but also offers potential avenues for intervention. Future research should assess the effectiveness of methods to increase adolescent fruit consumption by focussing on both improving adolescents’ dietary self-efficacy and on targeting parental control, perceptions and barriers.

Application of power functions to chromatographic data for the enhancement of signal to noise ratios and separation resolution

Chromatographic detection responses are recorded digitally. A peak is represented ideally by a Guassian distribution. Raising a Guassian distribution to the power ‘n’ increases the height of the peak to that power, but decreases the standard deviation by √n. Hence there is an increasing disparity in detection responses as the signal moves from low level noise, with a corresponding decrease in peak width. This increases the S/N ratio and increases peak to peak resolution. The ramifications of these factors are that poor resolution in complex chromatographic data can be improved, and low signal responses embedded at near noise levels can be enhanced. The application of this data treatment process is potentially very useful in 2D-HPLC where sample dilution occurs between dimension, reducing signal response, and in the application of post-reaction detection methods, where band broadening is increased by virtue of reaction coils. In this work power functions applied to chromatographic data are discussed in the context of (a) complex separation problems, (b) 2D-HPLC separations, and (c) post-column reaction detectors.

Reducing parental anxiety using a family based intervention for youth mental health : a randomized controlled trial

This paper presents findings on parent anxiety and attachment relationship style from the Deakin Family Options (DFO) pilot study, a randomized controlled pilot study comparing a family-based treatment (BEST Plus), versus a youth only treatment (CBT) versus a group who received both of these treatments (COMBINED). Eligible participants were families with a young person (aged 12 - 25 years) with a high prevalence mental health problem. Youth from participating families scored in the clinical or subclinical range for depression, anxiety and/or substance misuse symptoms on standardized measures during the initial assessment. The collected sample was drawn from regional and urban centers in Victoria, Australia and allocated to treatment condition using a simple randomization procedure (parallel design). It was hypothesized that families receiving the BEST Plus would experience greater reductions in youth and parent mental health symptoms, and improved parent-child relationships, compared with those in the CBT condition. This paper describes and discusses changes in parent anxiety and parent attachment, according to whether the parent participated in a treatment (BEST Plus) or did not (NONBEST Plus). Participants were blind to the study hypotheses. In total 71 parent participants returned pre data and were allocated to a treatment group. In this paper, data from parent participants who completed pre and post measures (n = 48) and pre, post, and 6-month follow-up measures (n = 28) on anxiety and attachment were analyzed by group (BEST Plus versus NONBEST Plus). The results of this study suggest that parent anxiety decreased significantly more following parent involvement in a group treatment, than for parents that did not receive treatment. Unexpectedly, avoidant attachment increased in the no treatment group, but remained relatively stable following the BEST Plus group. There were no significant findings in relation to compulsive traits and anxious attachment. These findings are discussed in light of the study limitations.

A review of flight-initiation distances and their application to managing disturbance to Australian birds

Disturbance - the response of birds to a stimulus such as the presence of a person - is considered a conservation threat for some Australian birds. The distance at which a bird flees from perceived danger is defined as the flight-initiation distance (FID), and could be used to designate separation distances between birds and stimuli that might cause disturbance. We review the known FIDs for Australian birds, and report FIDs for 250 species. Most FIDs are from south-eastern Australia, and almost all refer to a single walker as the stimulus. Several prominent factors correlated with FID are discussed (e.g. body mass and the distance at which an approach begins). FIDs have not been used extensively in the management of disturbance, for a variety of reasons including lack and inaccessibility of available data. We call for standardised data collection and greater application of available data to the management of disturbance.

How parental and school responses to choice policies reconfigure a rural education market in Victoria, Australia

Market principles now dominate the education and social policies of many Anglophone countries, including Australia, but articulate differentially within specific contexts. Existing historical legacies, local economic and social conditions, and geographical settings interact with federal and state funding and transport policies to shape the nature of regional education markets and the choices families make in a rural school market in Australia. Through two school case studies, this article explores the effects of policy shifts on parental choice and student movement within a regional Victorian community. Informed by policy sociology, the article views the policy as a dynamic, often ad hoc process with contradictory effects. It indicates how an ensemble of federal and state funding and conveyancing policies enable some schools to develop marketing practices that reconstruct the local education market to their advantage through the introduction of transport and flexi-boarding policies. It demonstrates that education markets are not confined to urban settings and that while choice is not a new phenomenon in this rural area, federal and state funding and transport policies have reconfigured local markets and intensified the market work undertaken by schools and parents with, in this instance, unequal effects on the provision of schooling in a rural region.

Tribes and conflict management in Iraq

Since the US-led invasion of Iraq in 2003, this country has witnessed an unprecedented sectarian atmosphere. The newly installed political system by the US has institutionalised the ethno-sectarian nature of the political “democratic” scene and the influx of al-Qaida and other militia were exacerbating the violent context. The post- invasion formed State apparatus has been crippled and not been capable of taking control, enforcing law, restoring order and establishing sustainable reconciliation. Within this context, tribes have emerged as a powerful disciplinary social structure that is capable of conflict management and national reconciliation. Based on empirical data collected from Iraq, this paper discusses the roles of Iraqi tribes in peaceful reconciliation processes. It further engages with the tribal discourses and communication methods used in this process to contribute to bringing stability to the country. Tribes have applied different modes of communications and methods of conflict management at different individual, communal and national levels.
