未発効条約の実効性確保：CTBTを事例として
Get PDFapplication/pdf核実験禁止は、核兵器開発に不可欠な核実験を禁止することにより核兵器開発および質的改善を抑制する効果的な措置であることから、核軍縮・核不拡散分野における国際社会の最優先の目標のひとつとされ、これまで核実験禁止のための多数国間条約としては、部分的核実験禁止条約（PTBT）および包括的核実験禁止条約（CTBT）が作成されている。特に、CTBTについては核軍縮・不拡散体制の基礎となる核兵器不拡散条約（NPT）との関連でも重視されているにもかかわらず、1996年9月に署名開放されてから20年が経過した今日においても発効の見通しが立っておらず、CTBTの未発効状態に起因する法的問題を始めこれまでも多くの識者が取り上げている。本稿においては、CTBTO準備委員会の法的地位、CTBTの暫定適用、暫定実施および現在CTBTO準備委員会により行われているCTBTの検証制度の暫定運用を検討材料として、CTBTの未発効状態が今後も継続する可能性が高い中で、CTBTの趣旨と目的を達成することが可能かについて考察する。p.59の巻，出版年 (誤植) : Vol.6, 2015journal articl

Historical Study of Japanese Olympians Killed in War : Reconstructing the Roster Brought to Berlin by Kenkichi Oshima
No full textapplication/pdfThis study clarifies the number of Japanese Olympians killed in war or by violence. The Sports Museum in Berlin has been gathering the names of Olympians who have fallen victim to acts of violence or war in order to honor them and to appeal for a peaceful world. Currently, the museum has a roster with the names of only five Japanese victims. In 1982, Kenkichi Oshima (A member of the Japanese Olympic Committee) should have brought a list of 30 additional names to Berlin in order to add them to the pedestal of the Olympic bell at Berlin Olympic Stadium. However, it is impossible now not only to find the roster but even to locate the pedestal for the Olympic bell in Berlin. At the same time, Yasukuni Shrine has a list of 31 other Olympians from Japan who became war victims. We make it clear why it's different in three Lists. Our research compares and adjusts these three different lists. As a result, we propose that a new roster should be made with the names of 37 Japanese victims.journal articl
Extending the Peak Bandwidth of Parameters for Softmax Selection in Reinforcement Learning
Get PDFapplication/pdfSoftmax selection is one of the most popular methods for action selection in reinforcement learning. Although various recently proposed methods may be more effective with full parameter tuning, implementing a complicated method that requires the tuning of many parameters can be difficult. Thus, softmax selection is still worth revisiting, considering the cost savings of its implementation and tuning. In fact, this method works adequately in practice with only one parameter appropriately set for the environment. The aim of this paper is to improve the variable setting of this method to extend the bandwidth of good parameters, thereby reducing the cost of implementation and parameter tuning. To achieve this, we take advantage of the asymptotic equipartition property in a Markov decision process to extend the peak bandwidth of softmax selection. Using a variety of episodic tasks, we show that our setting is effective in extending the bandwidth and that it yields a better policy in terms of stability. The bandwidth is quantitatively assessed in a series of statistical tests.journal articl
