Becoming Exceptional: Exploring selves and assemblages in the National Exceptional Teaching in Disadvantaged Schools program

This paper explores the work of ‘becoming exceptional’ amongst a group of preservice teachers taking part in the National Exceptional Teaching for Disadvantaged Schools program (NETDS). The NETDS program is directed towards mentoring and supporting outstanding preservice teachers to transition into the schools where they can make a significant difference. For us, as teacher educators leading the teaching of our University’s NETDS program, the most important questions became ones of self and transformation for the participating preservice teachers. To begin these explorations we make use of concepts provided by Deleuze and Guattari, and expanded upon by Braidotti; the notions of ‘becoming’ and ‘collective assemblages’. These concepts help us explore the work of becoming exceptional within the collective assemblage and space of the NETDS program

Inferring the eccentricity distribution

Standard maximum-likelihood estimators for binary-star and exoplanet eccentricities are biased high, in the sense that the estimated eccentricity tends to be larger than the true eccentricity. As with most non-trivial observables, a simple histogram of estimated eccentricities is not a good estimate of the true eccentricity distribution. Here we develop and test a hierarchical probabilistic method for performing the relevant meta-analysis, that is, inferring the true eccentricity distribution, taking as input the likelihood functions for the individual-star eccentricities, or samplings of the posterior probability distributions for the eccentricities (under a given, uninformative prior). The method is a simple implementation of a hierarchical Bayesian model; it can also be seen as a kind of heteroscedastic deconvolution. It can be applied to any quantity measured with finite precision--other orbital parameters, or indeed any astronomical measurements of any kind, including magnitudes, parallaxes, or photometric redshifts--so long as the measurements have been communicated as a likelihood function or a posterior sampling.Comment: Ap

Trade Secret Law and Information Systems: Can Your Students Keep a Secret?

The impact of intellectual property (IP) law on information systems (IS) professionals in business cannot be overstated. The IS 2010 model curriculum guidelines for undergraduate IS programs stress the importance of information security and knowledge about IP. While copyright and patents are the most well-known types of IP, another, trade secrets, which involve confidential information generated by business to secure financial success, poses a unique challenge partly because IS professionals are often less familiar with trade secrets as a form of IP. Just as important is the crucial role IS plays in actually creating trade secrets. Information must not only be vital and proprietary but also its secrecy must be actively protected and maintained against data security challenges, including unethical behavior by disgruntled employees, corporate espionage, and inadvertent disclosure. Failure to do so results in a determination that information is not legally a protected trade secret. Unlike copyrights and patents, information cannot publically be designated as a trade secret prior to a challenge. Instead, organizations must prove the information is actually a trade secret. Critical to this proof are processes and internal systems businesses use to maintain information secrecy, which determine whether legal remedies exist if the trade secret is wrongfully divulged. This paper discusses trade secret law, methods used to secure trade secrets, and the role of IS in supporting and/or developing those methods. A class exercise provides IS students with insights into trade secret law and acceptable, ethical conduct of IS professionals who protect trade secrets

School exclusion in children with psychiatric disorder or impairing psychopathology: a systematic review

This is an Accepted Manuscript of an article published by Taylor & Francis in Emotional and Behavioural Difficulties on 20 August 2014, available online: http://wwww.tandfonline.com/10.1080/13632752.2014.945741Childhood psychiatric disorders are associated with a wide range of adverse outcomes including poor academic attainment. For some children these difficulties are recognised through school Special Educational Need procedures (SEN) but many others may remain unidentified and/or unsupported. In Britain, government data suggests disproportionate representation of children with a SEN among children permanently excluded from school. This review asks whether school-aged children with impairing psychopathology were more likely to be excluded from school than those without. Databases covering education, social sciences, psychology and medicine were searched, experts were contacted and bibliographies of key papers were hand-searched. Studies were included if the population covered school-aged children, and if validated diagnostic measures had been used to assess psychopathology. Children with impairing psychopathology had greater odds of exclusion compared to the rest of the school-age population: odds ratios range from 1.13 (95% CI: 0.55–2.33) to 45.6 (95% CI: 3.8–21.3). These findings however need to be considered in light of the paucity of the literature and methodological weaknesses discussed.National Institute for Health Research (NIHR) Collaboration for Leadership in Applied Health Research and Care (CLAHRC) for the South West Peninsula

Data logging and performance analysis software for teachers of indigenous New Zealanders: early results

Technology, in the form of personal computers, is making inroads into everyday life in every part of every nation. It is frequently assumed that this is 'a good thing'. However, there is a need for the people in each cultural group in each nation to appropriate technology for themselves. Indigenous people, such as the Maori of New Zealand/Aotearoa, are in danger of losing their language because technology has a European face. Yet despite the fact that the Maori are currently experiencing a cultural renaissance, there are no commercially available products that are specifically designed for Maori-speaking people

Non-pharmacological interventions for ADHD in school settings: an overarching synthesis of systematic reviews

OBJECTIVE: This overarching synthesis brings together the findings of four systematic reviews including 138 studies focused on non-pharmacological interventions for ADHD used in school settings. These reviews considered the effectiveness of school-based interventions for ADHD, attitudes toward and experience of school-based interventions for ADHD, and the experience of ADHD in school settings. METHOD: We developed novel methods to compare the findings across these reviews inductively and deductively. RESULTS: Key contextual issues that may influence the effectiveness and implementation of interventions include the relationships that pupils with ADHD have with their teachers and peers, the attributions individuals make about the etiology of ADHD, and stigma related to ADHD or intervention attendance. CONCLUSION: Although we found some positive effects for some outcomes and intervention categories, heterogeneity in effect size estimates and research evidence suggests a range of diverse contextual factors potentially moderate the implementation and effectiveness of school-based interventions for ADHD.National Institute for Health Research Health Technology Assessment (NIHR HTA) programNIHR Collaboration for Leadership in Applied HealthResearch and Care South West Peninsula (PenCLAHRC

Time Protection: the Missing OS Abstraction

Timing channels enable data leakage that threatens the security of computer systems, from cloud platforms to smartphones and browsers executing untrusted third-party code. Preventing unauthorised information flow is a core duty of the operating system, however, present OSes are unable to prevent timing channels. We argue that OSes must provide time protection in addition to the established memory protection. We examine the requirements of time protection, present a design and its implementation in the seL4 microkernel, and evaluate its efficacy as well as performance overhead on Arm and x86 processors

The process, outcomes, and challenges of feasibility studies conducted in partnership with stakeholders: A health intervention for women survivors of intimate partner violence

Feasibility studies play a crucial role in determining whether complex, community-based interventions should be subject to efficacy testing. Reports of such studies often focus on efficacy potential but less often examine other elements of feasibility, such as acceptance by clients and professionals, practicality, and system integration, which are critical to decisions for proceeding with controlled efficacy testing. Although stakeholder partnership in feasibility studies is widely suggested to facilitate the research process, strengthen relevance, and increase knowledge transfer, little is written about how this occurs or its consequences and outcomes. We began to address these gaps in knowledge in a feasibility study of a health intervention for women survivors of intimate partner violence (IPV) conducted in partnership with policy, community and practitioner stakeholders. We employed a mixed-method design, combining a single-group, pre-post intervention study with 52 survivors of IPV, of whom 42 completed data collection, with chart review data and interviews of 18 purposefully sampled participants and all 9 interventionists. We assessed intervention feasibility in terms of acceptability, demand, practicality, implementation, adaptation, integration, and efficacy potential. Our findings demonstrate the scope of knowledge attainable when diverse elements of feasibility are considered, as well as the benefits and challenges of partnership. The implications of diverse perspectives on knowledge transfer are discussed. Our findings show the importance of examining elements of feasibility for complex community-based health interventions as a basis for determining whether controlled intervention efficacy testing is justified and for refining both the intervention and the research design
