    This paper describes the two-year implementation evaluation of a problem-based engineering design challenge held in a virtual world. The team-based challenge was designed and facilitated by an aerospace research and education institute for middle and high school student competitors in both classrooms and afterschool programs across the U.S. An independent evaluation team examined participant experiences to consider the strengths of the challenge, as well as recommendations to enhance the effectiveness and efficiency of future challenges. Overall, the evaluation team found that the problem-centered design challenge offered the student competitors a unique and valuable opportunity to engage in real-life science and engineering problems with the support of advanced science, technology, and engineering resources and college-level and professional experts. Recommendations centered on needed adjustments to achieve and prepare for growth, support for teams, assessment refinement, and collaboration and other technology enhancement

    Aquest article se centra en una dimensió poc discutida, però important, de les experiències dels migrants i les minories a Anglaterra i Gal·les: els cementiris i crematoris de què disposen. Basat en una àmplia investigació amb comunitats locals i proveïdors de serveis en quatre ciutats casos d’estudi, aquest article ex-plora les diverses necessitats funeràries culturals i religioses a Anglaterra i Gal·les, els reptes que hi estan associats i les formes en què tant les comunitats com els proveïdors de serveis (p. ex.: planifica-dors i directors funeraris) hi responen. Destaquen vuit temes clau: i)l’oferta de cementiris; ii)l’oferta de crematoris; iii)l’oferta desigual per diferents grups migrants i minoritaris; iv)la diversitat en la diversitat; v)els canvis de patrons de repatriació;vi)el foment del diàleg;vii)la comprensió entre professionals icomunitats, i viii)la planificació dels cementiris com aespais de trobada.Este artículo se centra en una dimensión poco discutida pero importante de las experiencias de los migrantes y las mi-norías en Inglaterra y Gales: los cemen-terios y crematorios de que disponen.

It highlights seven key themes, namely:i)cemetery provision;ii)crematorium provision;iii)unequal provision across migrantand minority groups;iv)diversity within diversity;v)changing patterns of repatriation; vi)fostering dialogue;vii)understanding between profession-als and communities; and viii)planning for cemeteries as spacesof encounter. / Este artículo se centra en una dimensión poco discutida pero importante de las experiencias de los migrantes y las mi-norías en Inglaterra y Gales: los cemen-terios y crematorios de que disponen.

    Rules, Norms and Practices – A Comparative Study Exploring Disposal Practices and Facilities in Northern Europe

    We identify and analyse practices and management regimes around burial and handling of ashes across eight case study towns within six Northern European countries. We analyse management of cemeteries and crematoria gardens, majority practices and provision for minority communities, including various burial types, cremated remains, the re-use of graves, and costs for interments. Comparative data is drawn from analysis of national and local regulations, interviews with stakeholders, and observations at cemeteries and crematoria gardens. The findings show significant variation in national and local regulations and practices for burial and cremation particularly around the re-use of graves, handling of ashes and costs for grave space and cremation. We identify the opportunities and constraints of these variations in terms of accessibility, diversity and equality; and argue for national directions to avoid unequal treatment within nations. Furthermore, we stress the importance of a liberal and inclusive management of European cemeteries and crematoria gardens

    Muddled Boundaries of Digital Shrines

    International audienceBased on an online ethnography study of 274 YouTube videos posted during the Virginia Tech or the Newtown massacres, this article discusses how users resort to participatory media during such mediatized events to create a digital spontaneous shrine. The assemblage of this sanctuary on a website hosting billions of user-generated contents is made possible by means of folksonomy and website architecture, and a two-fold social dynamic based on participatory commitment and the institutionalization of a collective entity. Unlike “physical” spontaneous shrines erected in public spaces, these digital shrines connect the bereaved with provocative or outrageous contributions, notably tributes from school shooting fans using participatory media to commemorate the killer’s memory. This side effect, generated by the technical properties of the platform, compromises the tranquility of the memorial and muddles the boundaries and the contents of such sanctuaries

    Transformation of Cs-IONSIV® into a ceramic wasteform by hot isostatic pressing

    A simple method to directly convert Cs-exchanged IONSIV® IE-911 into a ceramic wasteform by hot isostatic pressing (1100 °C/190 MPa/2 hr) is presented. Two major Cs-containing phases, Cs2TiNb6O18 and Cs2ZrSi6O15, and a series of mixed oxides form. The microstructure and phase assemblage of the samples as a function of Cs content were examined using XRD, XRF, SEM and TEM/EDX. The chemical aqueous durability of the materials was investigated using the MCC-1 and PCT-B standard test methods. For HIPed Cs-IONSIV® samples, the MCC-1 normalised release rates of Cs were <1.57 × 10−1 g m−2 d−1 at 0–28 days, and <3.78 × 10−2 g m−2 d−1 for PCT-B at 7 days. The low rates are indicative of a safe long-term immobilisation matrix for Cs formed directly from spent IONSIV®. It was also demonstrated that the phase formation can be altered by adding Ti metal due to a controlled redox environment

    Intelligence within BAOR and NATO's Northern Army Group

    Get PDF
    During the Cold War the UK's principal military role was its commitment to the North Atlantic Treaty Organisation (NATO) through the British Army of the Rhine (BAOR), together with wartime command of NATO's Northern Army Group. The possibility of a surprise attack by the numerically superior Warsaw Pact forces ensured that great importance was attached to intelligence, warning and rapid mobilisation. As yet we know very little about the intelligence dimension of BAOR and its interface with NATO allies. This article attempts to address these neglected issues, ending with the impact of the 1973 Yom Kippur War upon NATO thinking about warning and surprise in the mid-1970s. It concludes that the arrangements made by Whitehall for support to BAOR from national assets during crisis or transition to war were - at best - improbable. Accordingly, over the years, BAOR developed its own unique assets in the realm of both intelligence collection and special operations in order to prepare for the possible outbreak of conflict
