    Instanton filtering for the stochastic Burgers equation

    Full text link
    We address the question whether one can identify instantons in direct numerical simulations of the stochastically driven Burgers equation. For this purpose, we first solve the instanton equations using the Chernykh-Stepanov method [Phys. Rev. E 64, 026306 (2001)]. These results are then compared to direct numerical simulations by introducing a filtering technique to extract prescribed rare events from massive data sets of realizations. Using this approach we can extract the entire time history of the instanton evolution which allows us to identify the different phases predicted by the direct method of Chernykh and Stepanov with remarkable agreement

    This research provides the first thorough investigation into, and analysis of, the literature on e-government metrics and has opened up the topic and literature to the practitioner community. The research focuses on English local government, in response to what the researcher had experienced as haphazard implementation of e-government. Supplementary explorations included official and unofficial reasons for the adoption of e-government, along with the role of politics and Politics – local, national and international. Until this research, the main focus for e-government measurement had been on targets or large and complex analyses suitable only for central government. Instead, this research proposes parsimonious measurement. Such measurement, reliant upon collating citizen feedback across delivery channels, will assist improvement to services and assist channel migration. This had never been examined before. Since the subject of the research was electronic government, an action research methodology was employed, using electronic research instruments to deliver surveys, provide survey results and to house research models and background. The researcher is a practitioner within the field, so the instruments were designed to cross-fertilize the academic and practitioner thinking on the subject. It is expected that the research tool, in the form of the weblog, will continue (in the longer term) to assist professionals in debating the use of metrics. Ongoing research will continue to stretch across the academic and practitioner boundaries. This research makes original contributions to knowledge by revealing the most appropriate mechanism for the management and use of e-government, amongst other mechanisms for service delivery in the public sector, especially considering smaller authorities

    Intelligence Studies: some thoughts on the state of the art

    Get PDF
    The paper is not intended to be a comprehensive review of the field of Intelligence Studies but summarises the major currents in research in this area, in the last twenty years. In addition, it suggests directions for future research concluding that Intelligence Studies represents a healthy and growing activity of great relevance to contemporary security governance. There are identified a few challenges for the development of the domain, mainly the fact that Anglo-American authors and subject matter continue to dominate the literature, and the fact that the relations between the academic institutions and intelligence agencies, the civil-military relations, have not always been easy

    What does the UK Police National Database tell us about the future of police intelligence?

    Developments in technology are transforming society, creating more opportunities for offenders and complicating the policing landscape. The challenge for law enforcement is to identify criminal patterns from an offender’s electronic traces and to provide actionable intelligence. However, these traces are held by diverse police forces and are rarely connected. In 2011, to overcome this challenge, the Police National Database (PND) was launched to provide a national intelligence overview from local data. This study examines the database, using a mixed-methods approach. Descriptive and inferential analyses of PND usage data highlight that different forces use the PND, and its various capabilities, with different levels of frequency. Thematic analyses of interviews and focus groups with PND users identified: specific examples of PND use, as well as its perceived strengths, perceived deficiencies, and future considerations. Implications for policing practice are discussed

    Work in progress: a novel method of creating an academic content repository

    Get PDF
    This paper outlines a project aimed at addressing the issue of the scalability of online academic support. This project is being run during the Autumn semester at the University of Southern Queensland (USQ) Toowoomba Australia, in conjunction with the Australian Digital Futures Institute. The study attached to the project will use Design-Based Research to evaluate the effectiveness of a simple, but innovative academic content and metadata creation tool referred to as Academic Assist. Academic Assist has been recently developed at USQ as a plug-in block for the moodle-based Learning Management System employed at USQ for its several hundred online subjects. The pilot project and associated study now extends over nine subjects, including three consecutive subjects in computer engineering; and covers faculties of Engineering, Education, Business, Science and Arts. Some preliminary results are presented here. Complete results of the study including acceptance surveys, expert reviews and usage statistics will be presented at FIE 2009

    Cooperative actors in domestic abuse and their association with prosecution: implications for the criminal justice system

    Get PDF
    Suggestions to increase prosecution rates in domestic abuse cases often focus on improving victim cooperation and evidence gathering. This study explores the impact of persons involved in abuse investigations by modelling five variables (victim cooperation; witness cooperation; presence of children; suspect admission; and presence of physical evidence) across 540 cases of domestic abuse. The presence of physical evidence, as well as victim and witness cooperation, all increased the likelihood of a charge against the suspect. However, suspect confession often resulted in a police caution, meaning no successful charge. The implications of these findings to improve investigation and prosecution are discussed

    Language Use Affects How Much an Immigrant Earns
