Whither Peace Studies? Fragmentation to a New Integration?
In spite of the surface appearance of flourishing, peace studies now faces a crisis of dilution and fragmentation though concerned voices have long warned against it. The root of the crisis is traced back to the years around 1970, when Johan Galtung proposed the theory of structural violence. At that time, there were heated debates about whether to broaden the research agenda to include poverty and underdevelopment or not. It is shown that, though it was a great contribution to peace studies, the theory of structural violence also brought about the excessive expansion of the research agenda of the discipline, because, according to the theory, every important social problem could be a legitimate research subject of peace studies. More than two decades after the debates, however, there have appeared several symptoms which show the reorientation of the discipline toward the original narrower focus on war and conflict. Since a simple return to the past is impossible, it is suggested that, by focusing on the issues of war and conflict, peace studies should try to eliminate one of the major obstacles to the final goal of peace in the broadest sense of the word. To complicate the matter, however, there have recently been debates between the narrower and wider agendas in security studies. The wider agenda in security studies tends to broaden peace studies as well because an issue or problem like environmental degradation is claimed to be a peace studies issue on the ground that it is a security issue. Thus, peace studies will have to tackle with the same problem for some time to come.
Globalization and University Peace Education
Canada prides itself on its image as a peacemaker. But rhetoric is not the same as reality, and when one surveys the status of peace studies in Canadian universities the gap between them becomes obvious. While defense and strategic studies are well established and generously funded  elds, peace studies is a low public priority. There are a few university courses in con ict resolution, some with a decidedly military or corporate bent, and a sprinkling of course offerings on peace. And there is a handful of peace studies centers.
Multi-layer inpainting on Chinese artwork
Digital inpainting uses spatial or frequency information to restore partially damaged/removed photos and artworks. Most restoration algorithms take a picture as a single layer. We propose a new approach, which subdivides a Chinese painting into several layers. Each layer is inpainted separately. The layer fusion mechanism then finds the optimal inpaint among layers, which are restored layer-bylayer. We apply the algorithm on Chinese and western drawing. The result shows a high PSNR value as well as a high user satisfaction. The demonstration of our work is available at: http://www.mine.tku.edu.tw/demos/inpaint.
