    A comprehensive review of the literature and historical background of NASA established a need for an easy-to-implement technological improvement to displaying procedures which is cost effective and risk reducing. Previous unsuccessful attempts have led this team to explore the practicality of using a mobile handheld device. The major products, inputs, resources, constraints, planning and effort required for consideration of this type of solution were outlined. After analyzing the physical, environmental, life-cycle, functional, and socio-technical requirements, a Functional Analysis was performed to describe the top-level, second-level, and third-level functions of the system requirements. In addition, the risk/value proposition of conversion to a new technology was considered and gave a blueprint for transitioning along with the tasks necessary to implement the device into the Vehicle Assembly Building's (VAB) current infrastructure. A Work Breakdown Structure (WBS) described the elemental work items of the implementation. Once the viability of this system was confirmed, a device was selected through use of technical design comparison methods including the Pugh Matrix and House of Quality. Comparison and evaluation of the Apple iPhone, Motorola Q, Blackberry, PC Notebook, and PDA revealed that the iPhone is the most suitable device for this task. This paper outlines the device design/ architecture, as well as some of the required infrastructure

    Initial impacts of global risk mitigation measures taken during the combatting of the COVID-19 pandemic

    Get PDF
    This paper presents an analysis of risk mitigation measures taken by countries around the world facing the current COVID-19 outbreak. In light of the current pandemic the authors collated and clustered (using harmonised terminology) the risk mitigation measures taken around the globe in the combat to contain, and since March 11 2020, to limiting the spread of the SARS-CoV-2 virus known to cause the Coronavirus disease 2019 (COVID-19). This overview gathers lessons learnt, provides an update on the current knowledge for authorities, sectors and first responders on the effectiveness and may allow enhanced prevention, preparedness and response for future outbreaks. Various measures such as mobility restrictions, physical distancing, hygienic measures, socio economic restrictions, communication and international support mechanisms have been clustered and are reviewed in terms of the nature of the actions taken and their qualitative early-perceived impact. At the time of writing, it is still too premature to express the quantitative effectiveness of each risk mitigation cluster, but it seems that the best mitigation results are reported when applying a combination of voluntary and enforceable measures.JRC.E.7-Knowledge for Security and Migratio

    Performance Management and Performance Measurement in the Education Sector

    Get PDF
    The paper examines several outstanding issues on the interface between the measurement of performance in primary and secondary education and the management of improved performance in this nationally important sector. These issues relate to the clarification of the objectives of the education system, the impact of performance reward systems, such as Performance Related Pay, t he role of resources in influencing educational outcomes, the reliability of existing methods of assessing educational performance, such as Data Envelopment Analysis and multivariate regression, and the need for an improved national comparative database if progress is to be made in several of these directions.Performance management; performance measurement; education; data envelopment analysis; quality control; knowledge management.

    M-health review: joining up healthcare in a wireless world

    In recent years, there has been a huge increase in the use of information and communication technologies (ICT) to deliver health and social care. This trend is bound to continue as providers (whether public or private) strive to deliver better care to more people under conditions of severe budgetary constraint

    The need for a whole life framework in electrical power system asset management and the problems with individual silo like asset management system contributions.

    Get PDF
    The asset management of electrical power systems both in industry and academia currently offers up a wide spectrum of engineering practices and guidance to detect, diagnose and to combat asset deterioration. In doing so research largely aims to better enable enhanced decision or prediction making in single engineering applications such as partial discharge or dielectric condition measurements. This paper reviews the current state of the art as related to electrical asset management and sets out how todays engineering and maintenance heavy approaches are insufficient to meet the nature of the complex adaptive (Generation, Transmission & Distribution) systems. Furthermore this paper explains the need for a truly holistic governance framework capable of managing such complexities for power companies by using complex adaptive system science whilst grounded in the engineering, business and socio-technical attributes that applied engineering makes possible. In addition this paper outlines how utilising retroductive case study with hypothesis framework represents the best approach in creating such a fully holistic asset management capability for power companies

    'When food kills': a socio-technical systems analysis of the UK Pennington 1996 and 2005 E. coli O157 Outbreak Reports

    Get PDF
    In 1996 and 2005, two of the largest E. coli O157 outbreaks occurred in the UK. Many people were infected after consuming meat resulting in a number of deaths. In the present study we applied a systems approach to both the outbreak reports to analyse and compare the accidents. Using the Accimap method of systems analysis, this study investigates the human errors and organisational issues involved in the outbreaks and why accidents such as these occur in the food production domain. The systems analysis carried out in this study on the two outbreaks indicates that there are both common as well as unique factors associated with the two outbreaks. The study concludes that it is necessary to address food safety from a systemic point of view and identify and solve the various problems that could arise in the system, in the pre-incubation period before the outbreak actually occurs

    Visions, Values, and Videos: Revisiting Envisionings in Service of UbiComp Design for the Home

    Get PDF
    UbiComp has been envisioned to bring about a future dominated by calm computing technologies making our everyday lives ever more convenient. Yet the same vision has also attracted criticism for encouraging a solitary and passive lifestyle. The aim of this paper is to explore and elaborate these tensions further by examining the human values surrounding future domestic UbiComp solutions. Drawing on envisioning and contravisioning, we probe members of the public (N=28) through the presentation and focus group discussion of two contrasting animated video scenarios, where one is inspired by "calm" and the other by "engaging" visions of future UbiComp technology. By analysing the reasoning of our participants, we identify and elaborate a number of relevant values involved in balancing the two perspectives. In conclusion, we articulate practically applicable takeaways in the form of a set of key design questions and challenges.Comment: DIS'20, July 6-10, 2020, Eindhoven, Netherland
