タイトル: Non-state violence and political order in democratized Indonesia著者: Okamoto, Masaaki抄録: In addition to the formal coercive apparatus of the state, the military, and the police, numerous groups and organizations that use or threaten to use violence to further their interests exist in every country. These include completely illegitimate organizations such as mafias and terrorist groups and more legitimate ones such as security companies, militias, and officially sanctioned vigilante groups that operate on the margins of legality and illegality. Using Indonesia as a case study, I focus on such violent groups, which have existed under every political regime in the country's history. Violent groups not only play a role in maintaining stability and order according to the state's expectations but also, during the democratization era, actively participate in formal politics, thus highlighting the importance of violence as a political resource. By examining the relationshi ...

タイトル: 基底関数展開による変位場推定における ボックスカー関数と3次B-スプライン関数の比較著者: 野末, 陽平; 深畑, 幸俊抄録: Present day crustal displacement rates are accurately observed by global navigation satellite system (GNSS). In estimating continuous displacement fields from spatially discrete GNSS data, the method of basis function expansion is a powerful tool. As basis functions, the boxcar function is the easiest to be implemented, while the cubic B-spline function has good nature in estimating continuous and smooth fields. In this study, we quantitatively compare the performance of the boxcars with that of the cubic B-splines, changing the basis-function interval

タイトル: Effect of Glass Composition on Luminescence and Structure of CsPbBr₃ Quantum Dots in an Amorphous Matrix著者: Zheng, Ruilin; Ueda, Jumpei; Shinozaki, Kenji; Tanabe, Setsuhisa抄録: Glass matrix embedding is an efficient way to improve the chemical and thermal stability of the halide perovskite QDs. However, CsPbX₃ QDs exhibit distinct optical properties in different glass matrixes, including photoluminescence (PL) peak position, PL peak width, and optical band gap. In this work, the temperature-dependent PL spectra, absorption spectra, high-energy X-ray structure factor S(Q), and pair distribution function (PDF) were integrated to analyze the structural evolution of CsPbBr₃ QDs in different glass matrixes. The results show that the lattice parameters and atomic spacing of CsPbBr₃ QDs are affected by the glass composition in which they are embedded. The most possibility can be attributed to the thermal expansion mismatch between CsPbBr₃ QDs and the glass matri ...
