    To “Sketch-a-Scratch”

    A surface can be harsh and raspy, or smooth and silky, and everything in between. We are used to sense these features with our fingertips as well as with our eyes and ears: the exploration of a surface is a multisensory experience. Tools, too, are often employed in the interaction with surfaces, since they augment our manipulation capabilities. “Sketch-a-Scratch” is a tool for the multisensory exploration and sketching of surface textures. The user’s actions drive a physical sound model of real materials’ response to interactions such as scraping, rubbing or rolling. Moreover, different input signals can be converted into 2D visual surface profiles, thus enabling to experience them visually, aurally and haptically

    Editorial: global entrepreneurial talent management challenges and opportunities for HRD

    Get PDF
    This special issue of the International Journal of HRD Practice, Policy and Research brings together on-going work from the Global Entrepreneurial Talent Management3 (GETM3) project. GETM3 is a European Union Research Innovation and Staff Exchange (RISE) project investigating the HRD implications of the way existing and future talent can be managed at work, harnessing the entrepreneurial attitudes and skills of young people. The project is both interdisciplinary and international, exploring the key challenges of managing this entrepreneurial talent within organizations. The scope and content of the project align neatly with the intent of the Journal of International Journal of HRD Practice, Policy and Research, not least the emphasis on practical HRD implications. Indeed, at the heart of GETM3 is an appreciation that true understanding and impact can only come from engagement with multiple stakeholders. This editorial provides a brief contextual overview of GETM3, focusing on its relevance for HRD, before providing a brief review of the articles and opinion/forum pieces that make up the special issue. Such explorations are certainly timely. Deloitte’s recent Global Human Capital survey highlights that organizations must re-invent their ability to learn. Indeed, the top rated trend for 2019, reflected by 86% of respondents, was the need to improve learning and development (Deloitte, 2019: 77). Related to this is the requirement for more dedicated evidence exploring the nature and impact of HRD (Gubbins, Harney, van der Werff, & Rousseau, 2018; Mackay, 2017), coupled with more directed attention to the process, rather than the content, of HRD interventions (Staats, 2019). The papers in this special issue certainly make a contribution to enhanced understanding and equally to bridging the seemingly ever widening theory-practice gap (Holden, 2019)

    Ghera: A Repository of Android App Vulnerability Benchmarks

    Full text link
    Security of mobile apps affects the security of their users. This has fueled the development of techniques to automatically detect vulnerabilities in mobile apps and help developers secure their apps; specifically, in the context of Android platform due to openness and ubiquitousness of the platform. Despite a slew of research efforts in this space, there is no comprehensive repository of up-to-date and lean benchmarks that contain most of the known Android app vulnerabilities and, consequently, can be used to rigorously evaluate both existing and new vulnerability detection techniques and help developers learn about Android app vulnerabilities. In this paper, we describe Ghera, an open source repository of benchmarks that capture 25 known vulnerabilities in Android apps (as pairs of exploited/benign and exploiting/malicious apps). We also present desirable characteristics of vulnerability benchmarks and repositories that we uncovered while creating Ghera.Comment: 10 pages. Accepted at PROMISE'1

    Designing a Design Thinking Approach to HRD

    Get PDF
    This article considers the value of design thinking as applied to a HRD context, Specifically, it demonstrates how design thinking can be employed through a case study drawn from the GETM3 programme. It reports on the design, development, and delivery of a design thinking workshop which was created to draw out and develop ideas from students and recent graduates about the fundamental training and skills requirements of future employment. While design thinking has been widely deployed in innovation and entrepreneurship, its application to HRD is still very much embryonic. Our overview illustrates how the key characteristics of the design thinking process resonate with those required from HRD (e.g. focus on end user, problem solving, feedback, and innovation). Our contribution stems from illuminating a replicable application of design system thinking including both the process and the outcomes of this application. We conclude that design thinking is likely to serve as a critical mind-set, tool, and strategy to facilitate HRD practitioners and advance HRD practice

    Exploring Research through Design in Animal-Computer Interaction

    Get PDF
    This paper explores Research through Design (RtD) as a potential methodology for developing new interactive experiences for animals. We present an example study from an on-going project and examine whether RtD offers an appropriate framework for developing knowledge in the context of Animal-Computer Interaction, as well as considering how best to document such work. We discuss the design journey we undertook to develop interactive systems for captive elephants and the extent to which RtD has enabled us to explore concept development and documentation of research. As a result of our explorations, we propose that particular aspects of RtD can help ACI researchers gain fresh perspectives on the design of technology-enabled devices for non-human animals. We argue that these methods of working can support the investigation of particular and complex situations where no idiomatic interactions yet exist, where collaborative practice is desirable and where the designed objects themselves offer a conceptual window for future research and development

    Reconfigurable Intelligent Surfaces for Rich Scattering Wireless Communications: Recent Experiments, Challenges, and Opportunities

    Full text link
    Recent advances in the fabrication and experimentation of Reconfigurable Intelligent Surfaces (RISs) have motivated the concept of the smart radio environment, according to which the propagation of information-bearing waveforms in the wireless medium is amenable to programmability. Although the vast majority of recent experimental research on RIS-empowered wireless communications gravitates around narrowband beamforming in quasi-free space, RISs are foreseen to revolutionize wideband wireless connectivity in dense urban as well as indoor scenarios, which are usually characterized as strongly reverberant environments exhibiting severe multipath conditions. In this article, capitalizing on recent physics-driven experimental explorations of RIS-empowered wave propagation control in complex scattering cavities, we identify the potential of the spatiotemporal control offered by RISs to boost wireless communications in rich scattering channels via two case studies. First, an RIS is deployed to shape the multipath channel impulse response, which is shown to enable higher achievable communication rates. Second, the RIS-tunable propagation environment is leveraged as an analog multiplexer to localize non-cooperative objects using wave fingerprints, even when they are outside the line of sight. Future research challenges and opportunities in the algorithmic design and experimentation of smart rich scattering wireless environments enabled by RISs for sixth Generation (6G) wireless communications are discussed.Comment: 7 pages, 5 figures, submitted to an IEEE Magazin
