    The focus of the present research was to investigate how Local Governments in Queensland were progressing with the adoption of delineated DM policies and supporting guidelines. The study consulted Local Government representatives and hence, the results reflect their views on these issues. Is adoption occurring? To what degree? Are policies and guidelines being effectively implemented so that the objective of a safer, more resilient community is being achieved? If not, what are the current barriers to achieving this, and can recommendations be made to overcome these barriers? These questions defined the basis on which the present study was designed and the survey tools developed.\ud \ud While it was recognised that LGAQ and Emergency Management Queensland (EMQ) may have differing views on some reported issues, it was beyond the scope of the present study to canvass those views.\ud \ud The study resolved to document and analyse these questions under the broad themes of: \ud \ud • Building community capacity (notably via community awareness).\ud • Council operationalisation of DM. \ud • Regional partnerships (in mitigation/adaptation).\ud \ud Data was collected via a survey tool comprising two components: \ud \ud • An online questionnaire survey distributed via the LGAQ Disaster Management Alliance (hereafter referred to as the “Alliance”) to DM sections of all Queensland Local Government Councils; and\ud • a series of focus groups with selected Queensland Councils\u

    Power law violation of the area law in quantum spin chains

    The sub-volume scaling of the entanglement entropy with the system's size, nn, has been a subject of vigorous study in the last decade [1]. The area law provably holds for gapped one dimensional systems [2] and it was believed to be violated by at most a factor of log(n)\log\left(n\right) in physically reasonable models such as critical systems. In this paper, we generalize the spin1-1 model of Bravyi et al [3] to all integer spin-ss chains, whereby we introduce a class of exactly solvable models that are physical and exhibit signatures of criticality, yet violate the area law by a power law. The proposed Hamiltonian is local and translationally invariant in the bulk. We prove that it is frustration free and has a unique ground state. Moreover, we prove that the energy gap scales as ncn^{-c}, where using the theory of Brownian excursions, we prove c2c\ge2. This rules out the possibility of these models being described by a conformal field theory. We analytically show that the Schmidt rank grows exponentially with nn and that the half-chain entanglement entropy to the leading order scales as n\sqrt{n} (Eq. 16). Geometrically, the ground state is seen as a uniform superposition of all ss-colored Motzkin walks. Lastly, we introduce an external field which allows us to remove the boundary terms yet retain the desired properties of the model. Our techniques for obtaining the asymptotic form of the entanglement entropy, the gap upper bound and the self-contained expositions of the combinatorial techniques, more akin to lattice paths, may be of independent interest.Comment: v3: 10+33 pages. In the PNAS publication, the abstract was rewritten and title changed to "Supercritical entanglement in local systems: Counterexample to the area law for quantum matter". The content is same otherwise. v2: a section was added with an external field to include a model with no boundary terms (open and closed chain). Asymptotic technique is improved. v1:37 pages, 10 figures. Proc. Natl. Acad. Sci. USA, (Nov. 2016

    THE ECONOMIC CONTRIBUTION OF AGRICULTURE IN DELAWARE

    The decreasing share of production agriculture in the U.S. economy in general and Delaware in particular has raised questions about the amount of government resources being spent on the local agricultural sector. A basic question in the debate is: "What is the real economic contribution of agriculture?" This study looks at the economic role of agriculture in Delaware, presenting different perspectives of what agriculture is and what it contributes to the state economy. Based on three definitions of agriculture, the economic impacts as measured by shares to total employment, output, and value added were estimated using IMPLAN, an input-output modeling software. In each economic impact measure, the share of the local agricultural sector to the total Delaware economy ranged from around 2% to 6% in 1991.Agribusiness,

    Connectivity and Conflict in Periods of Austerity: What do we Know about Middle Class Political Activism and its Effects on Public Services?

    Get PDF
    There is concern that the middle classes enjoy advantages over less affluent social groups in relation to public service provision. Research on this question is, however, fragmented across policy fields and disciplines. This paper presents the results of a realist synthesis of academic research from the UK, US and Scandinavia since 1980. It shows that there is indeed evidence of middle class advantage in relation to public services, with the evidence most secure with respect to the UK, especially schooling, health and land use planning. It also notes, however, that there is insufficient evidence to identify the scale or import of additional benefit. The paper identifies four causal theories derived from the evidence which appear to explain how this advantage comes about. It offers an overview assessment of the strength of the evidence base in relation to both the mechanisms which underpin advantage, and the contexts which support these. It argues that middle class advantage accrues as a result of the interplay between the attitudes and activities of service users, service providers and the broader policy and social context. The paper argues for a more concerted research effort designed to determine the nature, extent and import of middle class advantage.

    Bourdieu and the Big Society: empowering the powerful in public service provision?

    Get PDF
    here is concern that the 'localism' promoted by the UK Coalition Government will further empower the already powerful. This paper uses Bourdieu's theory of practice to theorise middle-class public service use. Building on a previous evidence review (Matthews and Hastings, 2013) it considers whether the habitus of the middle-classes enables them to gain disproportionate benefit from public services. Service provision is understood as a 'field' marked by a competitive struggle between social agents who embody class-based power asymmetries. It finds that engagement with the state is a classed practice producing benefits to those already empowered and that localism may exacerbate inequalities

    Public-private partnership in disaster management: a case study of the Gold Coast

    Get PDF
    Public-private partnership has important roles to play in disaster management, including building business and community resilience, developing community risk awareness and providing essential services. This paper reports on two recent initiatives in public-private partnerships on Queensland's Gold Coast. The first is an initiative by a local community group 'Varsity Lakes Community Limited' to prepare a disaster management guide for the masterplanned community of Varsity Lakes with support from NRMA insurance company and the local council. The second is the 'Community Watch' program initiated by the Gold Coast City Council to involve local community groups in various parts of the City for building disaster resilience. These two examples provide insights on evolving disaster management public-private partnerships that are more communitybased and bottom-up by nature. The study indicates that there is potential for including an additional layer of 'community' when conceptualising the existing fourtiered (commonwealth, state, district and local government) disaster management framework of Queensland

    Miniaturized atmospheric ionization detector

    Get PDF
    A small scintillator-based detector for atmospheric ionization measurements has been developed, partly in response to a need for better ionization data in the weather-forming regions of the atmosphere and partly with the intention of producing a commercially available device. The device can measure both the count rate and energy of atmospheric ionizing radiation. Here we report results of a test flight over the UK in December 2017 where the detector was flown with two Geiger counters on a meteorological radiosonde. The count rate profile with height was consistent both with the Geigers and with previous work. The energy of incoming ionizing radiation increased substantially with altitude.Comment: Proc 18th Conference on Atmospheric Electricity, Nara, Japan, June 201
