Seasonal- and sex-specific correlations between dispersal and exploratory behaviour in the great tit

While the importance of personality in explaining individual dispersal strategies is increasingly recognized, limited information is still available on how patterns of personality-dependent dispersal may develop, hampering our understanding of the ecological significance of behavioural dispersal syndromes. Here, we examine the relative importance of personality at different stages of dispersal in the great tit, by analysing the sex-specific relationship between exploratory behaviour (EB; quantified in a novel environment) and dispersal distances in different seasons over the course of the first year of life (summer, autumn, winter, and until the first breeding attempt). In females, we found that EB was an important predictor of dispersal distances in summer and autumn, but only a weak to moderate correlation remained for females captured in winter or for natal dispersal distances based on first breeding records. We obtained a contrasting pattern at the population level, whereby male (but not female) immigrants captured in summer and autumn had higher EB scores than locally born birds, while this was not the case in birds captured in winter and those recruited as breeders into the population. In addition to providing further evidence for the existence of a behaviour dispersal syndrome in birds, our results show that correlations between EB and dispersal appear strongest at the early stages of the dispersal process, rather than being developed gradually. These findings show the importance of analysing the effect of phenotypic attributes on dispersal across different stages of the dispersal phenomenon and in each sex separately.

Duty and service in the Great War

One hundred years ago many Australian men valiantly went to fight in the Great War. They went for King and country, travel and adventure but there were also many, for very good and different reasons, who chose not to go. Historian Bart Ziino explores some of the conflicting and complex attitudes towards duty and service.

Family history and the Great War in Australia

The boom in family history that is a hallmark of so much historical activity around the globe over the last three decades is one contributor to the resurgence of interest in the Great War itself. In Australia, as elsewhere in the western world, family history and the resources dedicated to it have been expanding rapidly. This chapter investigates recent practices of family history of the Great War in Australia. Our aim is to examine the role of family history in producing and reproducing knowledge of the Great War within Australian families, and the relationship between the conduct and transmission of family history on the one hand, and the contours of cultural memory on the other.

The ‘great unwatched’ and the ‘lightly touched’: surveillance and stock market fraud

This chapter examines financial corporate crime, specifically the discontinuitiesand asymmetries in power that condition the differential uses of surveillance andsurveillance technologies in the governance of stock market fraud. It studiesstate and non-state control ('rule at a distance') (Rose and Miller 1992), theresistance practiced by the powerful economic actors who make up national andinternational equity trading markets, and the control efforts of regulatory agenciescharged with preventing, regulating and enforcing laws to counter stockmarket crime. At a theoretical level the study critiques the claims of surveillanceliteratures that technologically mediated surveillance, 'the new transparency',renders all social fields visible, and therefore knowable, manageable and governable(Haggerty and Ericson 2000), by documenting and interrogating how codeis used by powerful bankers, lawyers, accountants and stock brokers to construct'visibility covers' (Williams 2008: 1; Snider 2009; Braithwaite 2005).

Visual effects in great bowerbird sexual displays and their implications for signal design

It is often assumed that the primary purpose of a male's sexual display is to provide information about quality, or to strongly stimulate prospective mates, but other functions of courtship displays have been relatively neglected. Male great bowerbirds (Ptilonorhynchus nuchalis) construct bowers that exploit the female's predictable field of view (FOV) during courtship displays by creating forced perspective illusions, and the quality of illusion is a good predictor of mating success. Here, we present and discuss two additional components of male courtship displays that use the female's predetermined viewpoint: (i) the rapid and diverse flashing of coloured objects within her FOV and (ii) chromatic adaptation of the female's eyes that alters her perception of the colour of the displayed objects. Neither is directly related to mating success, but both are likely to increase signal efficacy, and may also be associated with attracting and holding the female's attention. Signal efficacy is constrained by trade-offs between the signal components; there are both positive and negative interactions within multicomponent signals. Important signal components may have a threshold effect on fitness rather than the often assumed linear relationship.

Great 'app-eal' but not there yet: a review of iPhone nutrition applications relevant to child weight management

Aims: There is increasing interest in the use of smartphone applications (apps) for delivering child obesity management interventions and supporting lifestyle behaviour change; however, there has been very little academic research on their development. Our aim is to review nutrition-related apps designed for children currently available in Australia for their usefulness in education or support behavioural interventions for child obesity. Methods: Apps available for download in iTunes Australia between 2 April and 3 June 2013 which were suitable for children >12 years were identified. Key words were chosen to identify apps applicable to children, focusing on nutrition. Results: A total of 27 apps were included. Most apps (24/27) were not based on evidence-informed recommendations. A third of apps were developed in the USA (n = 10; 37%) and were free (67%), nine apps required upfront payment, with a mean cost of $A2.80 (range $A0.99-$A7.49). The most common nutrition features were the promotion of energy balance (n = 12 apps) and guidance on appropriate portion size (n = 15). The most common behaviour change feature was goal setting (n = 15). The five apps that scored most highly against the characteristics reviewed were: Calorie Counter Pro by My Net Diary, Weight Watchers, Swap It Don't Stop It, Control My Weight by CalorieKing and Rate What I Ate-Photo Diet Tracker. Conclusions: Very few apps were identified that could be used in education or support behavioural interventions for child obesity. There is a need to harness this technology and evaluate the applicability and use within childhood obesity research interventions.

The Great War In Victorian Private Life - Mildura

Join Dr Bart Ziino as he examines the private experience of the Great War in Victoria, drawing on personal letters and diaries to tell a story of the war as an individual, familial, and communal trial. Through an examination of anxieties over loved ones at the front, and tensions over who was bearing the greater burden. This talk offers new ways of understanding the costs of the war, the capacities of Victorians to meet and endure its demands, and its increasingly corrosive social effects within their communities.

Illusions vary because of the types of decorations at bowers, not male skill at arranging them, in great bowerbirds

Many animals use extended phenotypes to attract mates, but the availability of suitable resources in the environment can affect the size and form of these signals, with unknown consequences for honest signalling. In some populations of the great bowerbird, Ptilonorhynchus nuchalis, males arrange decorations by size, with smaller decorations placed closer to the bower entrance than larger decorations. This may create a more even background pattern from the female's viewpoint within the bower than if decorations were arranged randomly. Males show consistent, individual variation in the size-distance gradient, which could reflect variation among males in the cognitive skills needed to arrange decorations. We examined whether individual consistency in gradient characteristics is related to a male's skill at decoration arrangement or the types of decorations at bowers. We paired 18 males and switched bower decorations between pairs. We measured gradient characteristics before switching and 4 and 8 days after switching. Gradient characteristics after switching were related to those of the bower from which decorations were received, not to those of the male's own bower before switching. Gradient characteristics were also related to the types of decorations received, including bones and snail shells. These results suggest that variation among males in the size-distance gradient is explained by differences in the availability of decorations at bowers, not the cognitive skills required to arrange decorations. Although variation in gradient characteristics could indicate the male's ability to locate and transport particular decorations, it could also reflect local availability of objects, with no relationship to male quality.

At home with the war: The Great War in Victorian private life. The 2014 Augustus Wolskel lecture

This article examines the Great War in Victoria through the lens of private sentiment. It exposes not only the diversity of perspectives and sentiment surrounding the war, but also the stresses endured by Victorians trying to reconcile their commitment to the war with personal and familial needs.Their experience was dominated by a confrontation with powerful currents of anxiety over the war and their loved ones, and increasing tensions within their communities over who was bearing the greater burdens of the war. Investigating private experience of total war at home allows us to see how Victorians made as well as endured the Great War, as their communities struggled to remain cohesive, and individuals struggled to cope with its demands.
