Effective interventions for working with young people who are homeless or at risk of homelessness

This literature review was commissioned by the Commonwealth Department of Families, Housing, Community Services and Indigenous Affairs (FaHCSIA). The aim of the review is to assess the current state of evidence about what interventions are most effective in working with young people who are homeless or at risk of homelessness. This literature review was produced in order to inform a broader project that identifies the range of interventions and strategies that are applied by Reconnect services and situates these practices within the existing evidence base (see separate report, Reconnect: working with young people who are homeless or at risk of homelessness). Reconnect is a community-based early intervention program for young people who are homeless or at risk of homelessness. It was established in 1998 as an early intervention response to youth homelessness. Reconnect uses early intervention strategies to help young people to stabilise and improve their housing, achieve family reconciliation, and improve their level of engagement with work, education, training and community. FaHCSIA funds Reconnect services to deliver services to young people aged 12–18 years (newly arrived young people 12–21 years) who are homeless or at risk of homelessness, and their families. Some Reconnect services focus on working with specific population groups, for example: Indigenous young people (Aboriginal or Torres Strait Islander people); young people experiencing mental health issues; and newly arrived young people. This review is guided by the key research question: ‘what are effective intervention strategies for working with young people who are homeless or at risk of homelessness?’ The literature review begins with a brief overview of youth homelessness as an issue of concern, its identified relevant risk and protective factors, and the relevance of early intervention. It then outlines the strategy for undertaking this literature review and presents the findings of the review

Understanding Individual Experiences of Chronic Illness with Semantic Space Models of Electronic Discussions

Electronic discussion groups provide a convenient forum for individuals to share their experiences of chronic illness. The language use of individual participants, and the way their language shifts over time, may provide implicit indications of important shifts in sense-of-self. This paper relates experience with application of the hyperspace analogue to language (HAL) model for automatic construction of a dimensional model from a corpus of text. HAL is applied to 17 months of discussion on a closed list of 20 women coping with chronic illness. The discussion group was moderated for a focus the phenomenon of "Transition' - how people can learn to incorporate the consequences of illness into their lives. The current phase of research focuses on identification of clusters of words that can represent key aspects of Transition. The HAL models for two participants have been analyzed by experts in Transition to form candidate clusters. These clusters are then used as a basis for contrasting the language usage of an individual participant over time as compared to the entire corpus. We have not yet found a reliable basis for identifying transitions in an individual based on their entries into a discussion forum, although the clusters may have some inherent value for introspection on individual experiences and Transition in general. We report challenges for interpretation of the HAL model related to the correlation of dimensions and the impact of group dynamics

ARC Discovery Grant Project: Challenges, possibilities and future directions : A national assessment of Australia's children's courts. ACT Report

This report summarises the findings of the Australian Capital Territory (ACT) component of the Australian Research Council funded Discovery Project: Challenges possibilities and future directions: a National Assessment of Australia’s Children’s Courts. This project was funded by an Australian Research Council Discovery Grant. The ACT study was one of nine parallel studies – one covering each state and territory and the ninth, based on the eight others, focusing on Australia as a whole. Each study had its own set of Chief Investigators and in the ACT these were Professor Peter Camilleri and Professor Morag McArthur. A book, published by Springer, is under preparation which will outline the findings of each jurisdiction and of the national research project

The Dilemma of Foraging Herbivores: Dealing with Food and Fear

For foraging herbivores, both food quality and predation risk vary across the landscape. Animals should avoid low-quality food patches in favour of high-quality ones, and seek safe patches while avoiding risky ones. Herbivores often face the foraging dilemma, however, of choosing between high-quality food in risky places or low-quality food in safe places. Here, we explore how and why the interaction between food quality and predation risk affects foraging decisions of mammalian herbivores, focusing on browsers confronting plant toxins in a landscape of fear. We draw together themes of plant–herbivore and predator–prey interactions, and the roles of animal ecophysiology, behaviour and personality. The response of herbivores to the dual costs of food and fear depends on the interplay of physiology and behaviour. We discuss detoxification physiology in dealing with plant toxins, and stress physiology associated with perceived predation risk. We argue that behaviour is the interface enabling herbivores to stay or quit food patches in response to their physiological tolerance to these risks. We hypothesise that generalist and specialist herbivores perceive the relative costs of plant defence and predation risk differently and intra-specifically, individuals with different personalities and physiologies should do so too, creating individualised landscapes of food and fear. We explore the ecological significance and emergent impacts of these individual-based foraging outcomes on populations and communities, and offer predictions that can be clearly tested. In doing so, we provide an integrated platform advancing herbivore foraging theory with food quality and predation risk at its core

Auxetic response of additive manufactured cubic chiral lattices at large plastic strains

Auxetic lattices exhibit a negative Poisson’s ratio and excellent energy absorption capability. Here, we investigate the compressive performance of auxetic cubic chiral structures. By utilising finite element analysis (FEA) verified by interrupted mechanical testing and x-ray computed tomography, the auxeticity and failure mechanisms at the large strain deformation have been evaluated. The FEA results show that the initial elastic–plastic response agrees with the prediction of the classic scaling laws of bending-dominated lattices. At increasing plastic deformation, the energy absorption and auxeticity are dependent on relative density, i.e., the slenderness ratio, of the constitutive struts. In the plastic regime, the auxeticity decreases with relative density. Ductile fracture precedes densification in relative densities above 1.2%, thus dictating a new scaling law for the variation of the maximum energy absorbed with density. The numerical model predicts the scaling of mechanical properties, fracture strains, and energy absorption of the constitutive unit cell and finite-sized specimens in the relative density ranging from 0.3% to 6.5%. However, to accurately model the failure mechanism, geometrical imperfections should be included. The scaling laws derived from this work may aid the design of next generation auxetic lattices with tailored mechanical properties

Scotland's Energy Future

Objectives and Approach • No energy policy, no matter how well considered, will ever solve all of the problems and paradoxes of energy supply and use. • Those developing policy must ask how best to address the competing issues of the ‘energy quadrilemma’: addressing climate change; ensuring affordability; providing energy security; and developing energy policy which is acceptable to the public, economically sustainable and just. • Decision makers will need to be honest with the public about what is achievable, what choices must be made, and what changes will need to occur

ω-Conotoxin GVIA mimetics that bind and inhibit neuronal Cav2.2 ion channels

The neuronal voltage-gated N-type calcium channel (Cav2.2) is a validated target for the treatment of neuropathic pain. A small library of anthranilamide-derived ω-Conotoxin GVIA mimetics bearing the diphenylmethylpiperazine moiety were prepared and tested using three experimental measures of calcium channel blockade. These consisted of a 125I-ω-conotoxin GVIA displacement assay, a fluorescence-based calcium response assay with SH-SY5Y neuroblastoma cells, and a whole-cell patch clamp electrophysiology assay with HEK293 cells stably expressing human Cav2.2 channels. A subset of compounds were active in all three assays. This is the first time that compounds designed to be mimics of ω-conotoxin GVIA and found to be active in the 125I-ω-conotoxin GVIA displacement assay have also been shown to block functional ion channels in a dose-dependent manner
