Undressing and redressing the harlequin: An Australian designer\u27s perspective

In undressing and redressing the Harlequin from an Australian designer’s perspective, the question is why has the Harlequin costume endured for over 500 years and in locations far away from its country of origin? Why do we associate its lozenge pattern with energetic joyous mischief? What are the Harlequin costume codes and how have they been manifested in Australia? The thesis components are divided as follows: The Designer’s Notebook is a pictorial and historical review of the iconic costume, which is made up of a complex patchwork of triangles where colour placements form a diamond pattern called a lozenge. The Harlequin, a stock character from commedia dell’arte, who emerged in Italy and France during the 1500s, wears the lozenge costume. The notebook traces possible connections and reasons for the emergence of both the costume and the Harlequin figure prior to his catalyzation as a character in commedia dell’arte. Having arrived at the manifestation of Harlequin and his lozenge costume, the focus moves to the forms of expression in which he has participated and the mutations which have occurred in the costume. Harlequin High Jinks Down Under is concerned with the manifestation of both the harlequinesque figure and its associated costume codes in circus and the harlequinades in Australia from the 1850s, when a kind of Australian larrikinism began to develop as the national identity. From this unique environment a century later sprang the satirist, Dame Edna Everage and the social and political comic, Joel Salom, associated with Circus OZ. On the international front, these Australian performers have joined comic book characters in keeping the harlequinesque costume codes alive, but something deeper is happening with the Harlequin and his lozenge attire. For instance, some philosophers have come to accept Harlequin as a visual code for the union of multi-nationalities. The Research additionally explores the enduring contribution of the lozenge code not only through the historical tracing of harlequinesque imagery but also through the designing of a 2 square meter art–piece created at an international residency in Vietnam to reflect the energetic universality of the lozenge form. Here Harlequin’s liminality is explored. Finally two new costume designs have been created for the Australian performers, Everage and Salom, to further the design of the harlequinesque into an imagined future

'[email protected]', an Auto/Biographical Study of Relationships with Food.

Popular discourses and current government policy focus on the need for individuals and families to make healthy food choices, without acknowledging the social and cultural milieu in which these are embedded. A neo-liberal focus on responsible individualism is part of a middle class habitus that ensures foodwork and foodplay are located within distinct heteronormative cultural fields. In my thesis I explore narratives from seventy-five mainly middle class respondents who engaged in a series of asynchronous online interviews over nine months beginning in November 2010. The themes that emerged aligned with public policy debates on the family, healthy eating, eating disorders, ‘fat’ bodies and elite foodways. Hence, feeding the family ‘healthy’ meals ‘prepared from scratch’ was considered a means of acquiring social, symbolic and cultural capital. ‘Fat’ talk and ‘lipoliteracy’ or learning to read the body were ways of performing femininity, whilst elite foodways were utilised as forms of hegemonic masculinities. Hence, in a challenge to the individualisation thesis my research demonstrates the complexity of food relationships beyond individual consumer choice. Throughout I adopt an auto/biographical approach that stresses the interconnectedness of biography and autobiography, focuses on researcher reflexivity and is sensitive to respondent subjectivities. Respondents used a common vocabulary of individuality, whilst simultaneously embedding themselves in family and kinship relations. Indeed, family, gender, and class, were the means of anchorage in a sea of remembering that engendered a sense of ontological security. Foodways are, thus, part of a habitus that is gendered, classed, temporal and historical. Women in the study conformed to cultural scripts of heteronormative femininity, whilst men resorted to hegemonic masculinities to distance themselves from feminised foodways and care work. These identities were not part of a negotiated family model, but located in cultural fields that reinforced and naturalised gendered divisions, they were bound by gender and class

The First Battle for Scottish Independence: The Battle of Dunnichen, A.D. 685.

This study is an examination of the historiography of the ancient-medieval texts that record events related to the Northumbrian and the Pictish royal houses in the seventh century. The Picts, the Scots and the Celtic Britons fell into subjugation under the control of the expansionist Northumbrian kings and remained there for most of the seventh century. Northumbrian expansion was halted by Bridei, king of the picts, when he put down the advancing Northumbrian forces of king Ecgfrith at the Battle of Dunnichen, also known as Nechtansmere, in the year A.D. 685. The outcome of the battle not only stopped Northumbrian expansion to the north, but began its reversal. The battle also allowed the Picts to gain back the lands they had lost to their Northumbrian enemy. For the Northumbrians, the battle had political and ecclesiastical implications that may have contributed to the later decline of their kingdom

Measurement properties of the Disability Rating Index in patients undergoing hip replacement

Objective. The aim of this study was to establish and validate the measurement properties of the Disability Rating Index (DRI) in a population of adults undergoing hip replacement. Methods. One hundred and twenty-six adults participating in a randomized controlled trial completed the Oxford Hip Score, Harris Hip Score, DRI and EuroQol Group–Five Dimensions (EQ-5D) questionnaires at four time points. The structural validity of the DRI was assessed using principal component analysis. Cronbach’s α was used to determine the internal consistency and scale reliability was also assessed. Correlation between the DRI and the other functional and health-related quality of life scales was used to check criterion validity. DRI responsiveness was estimated and the interpretability of the scale was also assessed by checking for edge effects. Results. Results of analyses showed that the DRI was internally consistent (Cronbach’s α = 0.92), had good association with both function-specific and general health-related quality of life scores and was sensitive to change (smallest detectable change = 2.7). No evidence of edge effects was found. Furthermore, structural assessment of the DRI revealed two novel subscales representing simple tasks and difficult tasks. Conclusions. The DRI is structurally valid, responsive and concurs with functional assessment in adults undergoing hip replacement

Scavenging vs hunting affects behavioral traits of an opportunistic carnivore

Background. Human-induced changes to ecosystems transform the availability of resources to predators, including altering prey populations and increasing access to anthropogenic foods. Opportunistic predators are likely to respond to altered food resources by changing the proportion of food they hunt versus scavenge. These shifts in foraging behavior will affect species interactions through multiple pathways, including by changing other aspects of predator behavior such as boldness, innovation, and social structure. Methods. To understand how foraging behavior impacts predator behavior, we conducted a controlled experiment to simulate hunting by introducing a prey model to captive coyotes (Canis latrans) and compared their behavior to coyotes that continued to scavenge over one year. We used focal observations to construct behavioral budgets, and conducted novel object, puzzle box, and conspecific tests to evaluate boldness, innovation, and response to conspecifics. Results. We documented increased time spent resting by hunting coyotes paired with decreased time spent active. Hunting coyotes increased boldness and persistence but there were no changes in innovation. Our results illustrate how foraging behavior can impact other aspects of behavior, with potential ecological consequences to predator ecology, predator-prey dynamics, and human-wildlife conflict; however, the captive nature of our study limits specific conclusions related to wild predators. We conclude that human-induced behavioral changes could have cascading ecological implications that are not fully understood

Microplastics interact with benthic biostabilization processes

J A H and D R P would like to acknowledge partial funding from Horizon 2020 European Research Council Consolidator Award (GEOSTICK, Grant 725955).Marine microplastics (MPs) accumulate in sediments but impacts on ecosystem functions are poorly understood. MPs interactions with stabilizing benthic flora/fauna or biostabilization processes, have not been fully investigated, yet this is critical for unraveling MPs effects on ecosystem-scale processes and functions. This is also vital for understanding feedback processes that may moderate the stock and flow of MPs as they are transported through estuaries. The relationships between sedimentary MPs, biota, environmental properties and sediment stability from field sediments, were examined using variance partitioning (VP) and correlation analyses. VP was used to identify common and unique contributions of different groups of variables (environmental, fauna and microplastic variables) to sediment stability. The influence of microplastic presence (fragment/fiber abundances and microplastic diversity) on sediment stability (defined using erosion thresholds and erosion rates) was demonstrated. Furthermore, MPs appeared to mediate the biostabilizing effects of environmental properties (including microorganisms) and fauna. Environmental properties and sediment stability could also explain the variation in MPs across sites suggesting biostabilizing properties may mediate the abundance, type and diversity of MPs that accumulate in the bed. The potential for MPs to influence biota and biostabilization processes and mediate microplastic resuspension dynamics within estuaries is discussed.Publisher PDFPeer reviewe

Effects of early‑life experience on innovation and problem‑solving in captive coyotes

Early-life experience often shapes behaviors like innovation and exploration. These behaviors are important to animals encountering novel food resources in diverse habitats, such as mesocarnivores in urban areas. To understand if early-life experiences impact later-life behavior, we examined how coyotes (Canis latrans) responded to a multi-access puzzle box at two life stages: pup (~ 7 weeks) and dispersal (~ 10 months). We first exposed pups, still living with their parents and littermates, to a baited puzzle box. At dispersal age, we again tested both these pups and an age-matched control group that was not exposed to the puzzle box as pups, both as individuals and with their pair-mate. We quantified problem-solving capability, latency to approach, and time spent in proximity to the puzzle box. Most pup litters solved two of the three access points, but no dispersal-age coyotes solved any access point. The amount of time dispersal-age coyotes spent near the box during pair-testing increased with (1) more time spent near the box during single-testing, (2) more time their pair-mate spent near the box during pair-testing, and (3) if their pair-mate came from a litter that previously solved the box. These results suggest that early-life experience and social interactions influence exploratory behavior at dispersal age, but coyotes exhibit increased avoidance behavior at this life stage, which corresponds with the life stage that overall survivorship decreases. Our study provides insight into how early-life experiences shape adult behavior in mesocarnivores

Effect of hydro-climate variation on biofilm dynamics and its impact in intertidal environments

Funding: This research has been supported by the European Research Council under the European Union's Horizon 2020 research and innovation program (grant no. 725955).Shallow tidal environments are very productive ecosystems but are sensitive to environmental changes and sea level rise. Bio-morphodynamic control of these environments is therefore a crucial consideration;however, the effect of small-scale biological activity on large-scale cohesive sediment dynamics like tidal basins and estuaries is still largely unquantified. This study advances our understanding by assessing the influence of biotic and abiotic factors on biologically cohesive sediment transport and morphology. An idealised benthic biofilm model is incorporated in a 1D morphodynamic model of tide-dominated channels. This study investigates the effect of a range of environmental and biological conditions on biofilm growth and their feedback on the morphological evolution of the entire intertidal channel. By carrying out a sensitivity analysis of the biomorphodynamic model, parameters like (i) hydrodynamic disturbances, (ii) seasonality, (iii) biofilm growth rate, (iv) temperature variation and (v) bio-cohesivity of the sediment are systematically changed. Results reveal that key parameters such as growth rate and temperature strongly influence the development of biofilm and are key determinants of equilibrium biofilm configuration and development under a range of disturbance periodicities and intensities. Long-term simulations of intertidal channel development demonstrate that the hydrodynamic disturbances induced by tides play a key role in shaping the morphology of the bed and that the presence of surface biofilm increases the time to reach morphological equilibrium. In locations characterised by low hydrodynamic forces, the biofilm grows and stabilises the bed, inhibiting the transport of coarse sediment (medium and fine sand). These findings suggest biofilm presence in channel beds results in intertidal channels that have significantly different characteristics in terms of morphology and stratigraphy compared abiotic sediments. It is concluded that inclusion of bio-cohesion in morphodynamic models is essential to predict estuary development and mitigate coastal erosion.Publisher PDFPeer reviewe
