    Maker Movements, Do-It-Yourself Cultures and Participatory Design: Implications for HCI Research

    Get PDF
    Falling costs and the wider availability of computational components, platforms and ecosystems have enabled the expansion of maker movements and DIY cultures. This can be considered as a form of democratization of technology systems design, in alignment with the aims of Participatory Design approaches. However, this landscape is constantly evolving, and long-term implications for the HCI community are far from clear. The organizers of this one-day workshop invite participants to present their case studies, experiences and perspectives on the topic with the goal of increasing understanding within this area of research. The outcomes of the workshop will include the articulation of future research directions with the purpose of informing a research agenda, as well as the establishment of new collaborations and networks

    Tritium Beta Decay, Neutrino Mass Matrices and Interactions Beyond the Standard Model

    The interference of charge-changing interactions, weaker than the V-A Standard Model (SM) interaction and having a different Lorentz structure, with that SM interaction, can, in principle, produce effects near the end point of the Tritium beta decay spectrum which are of a different character from those produced by the purely kinematic effect of neutrino mass expected in the simplest extension of the SM. We show that the existence of more than one mass eigenstate can lead to interference effects at the end point that are stronger than those occurring over the entire spectrum. We discuss these effects both for the special case of Dirac neutrinos and the more general case of Majorana neutrinos and show that, for the present precision of the experiments, one formula should suffice to express the interference effects in all cases. Implications for "sterile" neutrinos are noted.Comment: 32 pages, LaTeX, 6 figures, PostScript; full discussion and changes in notation from Phys. Lett.

    Gender and the European town: sites of political activity and citizenship

    No full text
    This volume offers an integrated set of local studies exploring the gendering of political activities across a variety of sites ranging from print culture, courts, government and philanthropic bodies and public spaces, outlining how a particular activity was constituted as political and exploring how this contributed to a gendered concept of citizenship. The comparative and transnational perspectives revealed through combining such work contributes to establishing new knowledge about the relationship between gender, citizenship and the development of the modern town in Northern Europe

    Wave Loadings acting on an innovative breakwater for energyproduction.

    The paper reports on 2D small scale experiments conducted to investigate wave loadings acting on a pilot project of device for the conversion of wave energy into electricity. The conversion concept is based on the overtopping principle and the structure is worldwide known with the acronym SSG. The hydraulic model tests have been carried out at the LInC laboratory of the University of Naples Federico II using random waves. Results indicate wave overtopping is able to cause a sudden inversion of vertical force under wave crest, so that it is alternatively upward and downward directed over a short time interval. It is also shown that two calculation methods widely employed in the Japanese design practice of vertical face breakwaters, namely Goda (1975) and Hiroi (1919), could be used to achieve safe estimates of the hydrodynamic loadings
