    Benefits and risks of emphasis adaptation in study workflows

    Get PDF
    This paper looks at the effect of highlighting in a study plan, represented as a workflow with prerequisites. We compare the effectiveness of highlighting when the adaptation was correct (participants responded quicker and more correctly), and when it did not highlight the most relevant tasks (detrimental effect). False statements took longer to process than positive statements (deciding about things that were not in the plan), but also surprisingly had lower error rates than positive statements. These findings imply that when the system makes errors in the adaptation this is harmful, and may cause students to incorrectly believe that they do not need to do certain tasks

    SecFlow: Adaptive Security-Aware Workflow Management System in Multi-Cloud Environments

    Full text link
    In this paper, we propose an architecture for a security-aware workflow management system (WfMS) we call SecFlow in answer to the recent developments of combining workflow management systems with Cloud environments and the still lacking abilities of such systems to ensure the security and privacy of cloud-based workflows. The SecFlow architecture focuses on full workflow life cycle coverage as, in addition to the existing approaches to design security-aware processes, there is a need to fill in the gap of maintaining security properties of workflows during their execution phase. To address this gap, we derive the requirements for such a security-aware WfMS and design a system architecture that meets these requirements. SecFlow integrates key functional components such as secure model construction, security-aware service selection, security violation detection, and adaptive response mechanisms while considering all potential malicious parties in multi-tenant and cloud-based WfMS.Comment: 16 pages, 6 figure

    Designing knowledge-matching facilities for scaling climate-smart agriculture: A proposal for accelerating food systems’ transformation in a changing climate

    Get PDF
    The brief talks about designing knowledge-matching facilities for scaling climate-smart agriculture. This is a priority discussed in the International Workshop on Scaling up and out of Climate-smart Technologies and Practices for Sustainable Agriculture (an initiative initiating from 2019-MACSG20), as well as of numerous CCAFS partners in the governments, research, donor, financial and policy institutions, civil society and private sectors. CCAFS proposes to join efforts, and outlines a way forward to develop and/or shape knowledge matching facilities for accelerating food systems transformation in a changing climate. This document is intended to be a living document that informs members and interested stakeholders about intermediate results and the planned or next steps

    Why climate change adaptation in cities needs customised and flexible climate services

    Get PDF
    AbstractCities are key players in climate change adaptation and mitigation due to a spatial concentration of assets, people and economic activities. They are thus contributing to and especially vulnerable to climate change. Identifying, planning, implementing and monitoring respective measures in cities is challenging and resource consuming. The paper outlines challenges for adaptation, discusses most common approaches and argues why implementation of theoretical methods has its shortcomings. Based on case studies, an innovative, practice-oriented approach has been tested to develop a climate service prototype product. It provides a general framework that allows a flexible and customised support for cities to adapt to expected impacts of a changing climate

    ATM automation: guidance on human technology integration

    Get PDF
    © Civil Aviation Authority 2016Human interaction with technology and automation is a key area of interest to industry and safety regulators alike. In February 2014, a joint CAA/industry workshop considered perspectives on present and future implementation of advanced automated systems. The conclusion was that whilst no additional regulation was necessary, guidance material for industry and regulators was required. Development of this guidance document was completed in 2015 by a working group consisting of CAA, UK industry, academia and industry associations (see Appendix B). This enabled a collaborative approach to be taken, and for regulatory, industry, and workforce perspectives to be collectively considered and addressed. The processes used in developing this guidance included: review of the themes identified from the February 2014 CAA/industry workshop1; review of academic papers, textbooks on automation, incidents and accidents involving automation; identification of key safety issues associated with automated systems; analysis of current and emerging ATM regulatory requirements and guidance material; presentation of emerging findings for critical review at UK and European aviation safety conferences. In December 2015, a workshop of senior management from project partner organisations reviewed the findings and proposals. EASA were briefed on the project before its commencement, and Eurocontrol contributed through membership of the Working Group.Final Published versio

    The need for a system view to regulate artificial intelligence/machine learning-based software as medical device

    Get PDF
    Artificial intelligence (AI) and Machine learning (ML) systems in medicine are poised to significantly improve health care, for example, by offering earlier diagnoses of diseases or recommending optimally individualized treatment plans. However, the emergence of AI/ML in medicine also creates challenges, which regulators must pay attention to. Which medical AI/ML-based products should be reviewed by regulators? What evidence should be required to permit marketing for AI/ML-based software as a medical device (SaMD)? How can we ensure the safety and effectiveness of AI/ML-based SaMD that may change over time as they are applied to new data? The U.S. Food and Drug Administration (FDA), for example, has recently proposed a discussion paper to address some of these issues. But it misses an important point: we argue that regulators like the FDA need to widen their scope from evaluating medical AI/ML-based products to assessing systems. This shift in perspective—from a product view to a system view—is central to maximizing the safety and efficacy of AI/ML in health care, but it also poses significant challenges for agencies like the FDA who are used to regulating products, not systems. We offer several suggestions for regulators to make this challenging but important transition
