Counter-terrorism across the policing continuum

Over the past two decades private and hybrid forms of policing have grown considerably in Australia. As a result, governments have begun to recognize the role played by non-state police agencies and personnel in the provision of public order and safety, further extending and legitimizing non-state policing. In addition, the private ownership of critical infrastructure and 'communal spaces' has led to a central role for non-state police in the area of 'high policing' counter-terrorism. In response to changes to the auspices and providers of policing, state police were beginning to explore new ways of working with private and hybrid forms of policing, with the emergence of a new type of experiment in policing partnerships, the Police-Private Security Committee (POLSEC). This paper examines these trends and implications for ongoing developments in Australian policing.

Finding a 'safe' place on the risk continuum: a case study of pregnancy and birthing in Lao PDR (Lao People's Democratic Republic)

This paper addresses two questions. Firstly: are the risk regimes faced, and perceived, by pregnant women in rural Lao PDR substantially different from those experienced by pregnant women in western societies? Secondly, if the Lao experiences and perceptions are different, can improvements in maternal health in Lao PDR be achieved without Laotians inheriting the risk regimes of late modernity experienced by many women in western societies? Secondary analysis is undertaken of data collected in 2005 for the evaluation of a pilot maternity waiting home in Bolikhan, Lao PDR. The results suggest significantly different risk perceptions and experiences between Lao and western communities, based on contrasting views of embodiment, identity construction and cosmologies. In the Lao rural communities studied, there is little evidence yet of 'risk society' despite the introduction of western technologies and practices to improve maternal mortality and morbidity. It is argued that 'risk society' can be avoided.

The diet of powerful owls (Ninox strenua) and prey availability in a continuum of habitats from disturbed urban fringe to protected forest environments in south-eastern Australia

This study investigates the diet of six breeding pairs of powerful owls in the Yarra Valley Corridor in Victoria, Australia, and compares prey consumption with prey availability. The six sites represent a continuum of habitats, ranging from urban Melbourne, through the urban fringe interface to a more forested landscape. We found that powerful owls in the Yarra Valley Corridor are reliant almost exclusively on arboreal marsupial prey as their preferred diet, with 99% of their overall diet comprising four arboreal marsupial species. These four species (the common ringtail possum, common brushtail possum, sugar glider and greater glider) were also the most abundant species observed while spotlighting; however, their abundance varied along the continuum. There was a strong positive relationship with the presence of these species in the diet and their site-specific availability, indicating that the powerful owl is a generalist hunter, preying on the most available prey at a given site and in a given season. This study suggests that food resources are high in these disturbed urban fringe sites and it is unlikely that food availability in urban environments will limit the potential survival of urban powerful owls.

Healthcare in continuum for an ageing population: national self monitoring or remote offshore monitoring for Australia?

Australia is a country, similar to other developed nations, confronting an ageing population with complex demographics. Ensuring continued healthcare for the ageing, while providing sufficient support for the already aged population requiring assistance, is at the forefront of the national agenda. Varied initiatives are with foci to leverage the advantages of lCTs leading to e-Health provisioning and assisted technologies. While these initiatives increasingly put budgetary constraints on local and federal governments, there is also a case for offshore resourcing of non-critical health services, to support, streamline and enhance the continuum of care, as the nation faces acute shortages of medical practitioners and nurses. However, privacy and confidentiality concerns in this context are a significant issue in Australia. In this paper, we take the position that if the National and state electronic health records system initiatives, are fully implemented, offshore resourcing can be a feasible complementary option resulting in a win-win situation of cutting costs and enabling the continuum of healthcare.

Is tendon pathology a continuum? A pathology model to explain the clinical presentation of load-induced tendinopathy

Overuse tendinopathy is problematic to manage clinically. People of different ages with tendons under diverse loads present with varying degrees of pain, irritability, and capacity to function. Recovery is similarly variable; some tendons recover with simple interventions, some remain resistant to all treatments.

The pathology of tendinopathy has been described as degenerative or failed healing. Neither of these descriptions fully explains the heterogeneity of presentation. This review proposes, and provides evidence for, a continuum of pathology. This model of pathology allows rational placement of treatments along the continuum.

A new model of tendinopathy and thoughtful treatment implementation may improve outcomes for those with tendinopathy. This model is presented for evaluation by clinicians and researchers.

Comparison of mechanical behaviour of thin film simulated by discrete dislocation dynamics and continuum crystal plasticity

3D finite element simulations of 9-grain multicrystalline aggregates are performed within the framework of the classical continuum crystal plasticity and discrete dislocation dynamics. The results are processed in a statistical way by ensemble averaging. The comparison is made at three levels: macroscopic stress–strain curves, average stress values per grain, local values of stress and plastic strain. The comparison shows that some similarities are observed in the stress and strain distributions in both simulations approaches. But there are also large discrepancies caused by the discrete nature of plasticity in DDD. The DDD simulations provide higher stress levels in the aggregate due to the small number of dislocation sources and to the stress field induced by individual dislocations.

Matching objects across the textured-smooth continuum

The problem of 3D object recognition is of immense practical importance, with the last decade witnessing a number of breakthroughs in the state of the art. Most of the previous work has focused on the matching of textured objects using local appearance descriptors extracted around salient image points. The recently proposed bag of boundaries method was the first to address directly the problem of matching smooth objects using boundary features. However, no previous work has attempted to achieve a holistic treatment of the problem by jointly using textural and shape features which is what we describe herein. Due to the complementarity of the two modalities, we fuse the corresponding matching scores and learn their relative weighting in a data specific manner by optimizing discriminative performance on synthetically distorted data. For the textural description of an object we adopt a representation in the form of a histogram of SIFT based visual words. Similarly the apparent shape of an object is represented by a histogram of discretized features capturing local shape. On a large public database of a diverse set of objects, the proposed method is shown to outperform significantly both purely textural and purely shape based approaches for matching across viewpoint variation.

A global heterothermic continuum in mammals

Aim: The ability of endotherms to physiologically regulate body temperature (Tb) is presumed to be important in the adaptive radiation of birds and mammals. Recently, attention has shifted towards determining the extent and energetic significance of Tb variation documented in an ever-expanding list of species. Thus, we provide the first global synthesis of ecological and evolutionary correlates of variation in mammalian Tb. Location: World-wide Methods: We conducted a phylogenetically informed analysis of Tb variation using two complementary metrics, namely Thermoregulatory Scope (TS) and Heterothermy Index (HI), that treat Tb variation as a continuous variable. We included morphological (e.g. body mass), ecological (e.g. food habits) and environmental (e.g. latitude) correlates in the analysis. Results: Among 560 mammal species included in the TS analysis, Tb relates most strongly to body mass (included in all models), season (relative parameter weight: 0.95), absolute latitude (0.80) and hoarding behavior (0.72), with small-bodied, high latitude and non-hoarding species expressing the most Tb variation. Small-bodied and high latitude species also express a greater range of thermoregulatory patterns than large-bodied and low latitude species. Results were generally similar in HI analysis, but in summer the extent of heterothermy decreases with latitude. Main conclusions: Mammalian heterothermy is related to evolutionary history, climate conditions constraining minimum Tb, resource conditions mediating energy supply for maintaining high Tb, and latitudinal variation in the nature of seasonality. Our analysis further shows that traditional classification of mammals as hibernators, daily heterotherms or homeotherms is clouded or possibly misleading.
