    Peace education in a time of war: the Museum of Peace in Rivne, Ukraine as a space of memory making and hope

    Get PDF
    Peace museums play an important role in peace education by offering visitors informal and non-formal education. As sites of remembrance, peace museums are rich pedagogical spaces for experiential learning and reflection. Educating children in the spirit of peace, tolerance and harmony between nations has been central to the work of the Museum of Peace in Rivne in Ukraine. Whilst peace museums usually engage in peacebuilding and memory making in times of peace, post conflict, this article reports on the work of the Museum in Rivne in a time of war. Wartime brings difficult questions about engaging in peacebuilding in the face of military aggression and about sustaining memory-making work when violent conflict makes memories too immediate and painful. As explained in the article, the reinvigorated peacebuilding effort at the Museum in Rivne demonstrates that, in a time of war, it is even more important to promote peace, in opposition to war. Through the annual event ‘I Vote for Peace’, the Museum has sought to create a network of schools committed to global tolerance and peacekeeping, as well as offer Ukrainian children a space for talking about their experiences and their hope for a peaceful future

    Three-dimensional micro structured nanocomposite beams by microfluidic infiltration

    Three-dimensional (3D) micro structured beams reinforced with a single-walled carbon nanotube (C-SWNT)/polymer nanocomposite were fabricated using an approach based on the infiltration of 3D microfluidic networks. The 3D microfluidic network was first fabricated by the direct-write assembly method, which consists of the robotized deposition of fugitive ink filaments on an epoxy substrate, forming thereby a 3D micro structured scaffold. After encapsulating the 3D micro-scaffold structure with an epoxy resin, the fugitive ink was liquefied and removed, resulting in a 3D network of interconnected microchannels. This microfluidic network was then infiltrated by a polymer loaded with C-SWNTs and subsequently cured. Prior to their incorporation in the polymer matrix, the UV-laser synthesized C-SWNTs were purified, functionalized and dispersed into the matrix using a three-roll mixing mill. The final samples consist of rectangular beams having a complex 3D skeleton structure of C-SWNT/polymer nanocomposite fibers, adapted to offer better performance under flexural solicitation. Dynamic mechanical analysis in flexion showed an increase of 12.5% in the storage modulus compared to the resin infiltrated beams. The nanocomposite infiltration of microfluidic networks demonstrated here opens new prospects for the achievement of 3D reinforced micro structures

    3^3He Structure and Mechanisms of p3p^3He Backward Elastic Scattering

    Get PDF
    The mechanism of p3p^3He backward elastic scattering is studied. It is found that the triangle diagrams with the subprocesses pd3pd\to ^3Heπ0 \pi^0, pd3pd^*\to ^3Heπ0 \pi^0 and p(pp)3p(pp)\to^3Heπ+ \pi^+, where dd^* and pppp denote the singlet deuteron and diproton pair in the 1S0^1S_0 state, respectively, dominate in the cross section at 0.3-0.8 GeV, and their contribution is comparable with that for a sequential transfer of a npnp pair at 1-1.5 GeV. The contribution of the d+ppd^*+pp, estimated on the basis of the spectator mechanism of the p(NN)3p(NN)\to ^3Heπ \pi reaction, increases the p3p^3He3\to ^3Hep p cross section by one order of magnitude as compared to the contribution of the deuteron alone. Effects of the initial and final states interaction are taken into account.Comment: 17 pages, Latex, 4 postscript figures, expanded version, accepted by Physical Review

    Heroes and villains of world history across cultures

Multidimensional scaling and factor analysis techniques found only limited forms of universality in evaluations across Western, Catholic/Orthodox, Muslim, and Asian country clusters. The highest consensus across cultures involved scientific innovators, with Einstein having the most positive evaluation overall. Peaceful humanitarians like Mother Theresa and Gandhi followed. There was much less cross-cultural consistency in the evaluation of negative figures, led by Hitler, Osama bin Laden, and Saddam Hussein. After more traditional empirical methods (e.g., factor analysis) failed to identify meaningful cross-cultural patterns, Latent Profile Analysis (LPA) was used to identify four global representational profiles: Secular and Religious Idealists were overwhelmingly prevalent in Christian countries, and Political Realists were common in Muslim and Asian countries. We discuss possible consequences and interpretations of these different representational profiles.This research was supported by grant RG016-P-10 from the Chiang Ching-Kuo Foundation for International Scholarly Exchange (http://www.cckf.org.tw/).

    Construction and demolition waste - a shift toward Lean Construction and Building Information Model

    Get PDF
    Waste in the construction industry is a devastating dilemma, especially that construction and demolition activities are considered as the highest waste generator globally. Countries have developed regulations: policy-makers and professional associations have provided norms and policies to manage C&D waste. Previous studies, however, have revealed insufficiencies in the current regulations and norms in incentivizing the industry practices toward waste prevention, since its culture is characterized by the gap in technological use, insufficient knowledge, poor planning, and poor information flow. This research provides a literature review on the current research findings and trends in managing C&D waste. Then based on design theory and theory of production, an exploratory research consisting of BIM and Lean construction concepts is provided. Lean can maximize the value of construction by addressing waste within portfolios, projects, and operations; BIM offers an enhanced collaborative platform with improved design practice and information management throughout buildings’ life cycle. The proposed conceptual framework enables economic, environmental, and social benefits to allow practitioners collaborate, analyze, and minimize construction waste throughout buildings’ life cycle.(undefined
