A geocultural power competition in UNESCO's Silk Roads project: China's initiatives and the responses from Japan and South Korea

Since Chinese President Xi Jinping announced the Belt and Road Initiative in 2013, China has increasingly engaged in UNESCO's Silk Roads project. China's emphasis on its western routes signals its strategic interest in the reconstruction of its historical connections that matches China's global networking in Eurasia, the Middle East, and Europe. However, whether China will successfully reformulate the international visions of the past, present, and future for its benefit remains an open question. This article focuses on the responses from Japan and South Korea, both of which hold critical positions as the owners of eastern Silk Roads heritage and the funders of UNESCO's Silk Roads heritage studies and World Heritage nomination assistance. Extending the conceptual framework of memory infrastructure to the study of heritage politics and diplomacy highlights the competitive aspect of a transnational heritage project in shaping and reshaping historical and contemporary geographical landscapes

Global Norm Diffusion in East Asia: How China and Japan Implement the Responsibility to Protect

This article addresses the problem of global norm diffusion in international relations with particular reference to the implementation of ‘the responsibility to protect’ (R2P) in East Asia. Exposing the limits of previous work on norm localization, we develop the framework of the norm diffusion loop. Rather than understanding norm diffusion as a linear top-down process, we demonstrate that the reception of R2P has evolved in a far more dynamic way that can best be described as a feedback loop. We first look into the processes and causal mechanisms that helped to construct R2P as an emerging transnational soft norm; then we analyse the challenges of diffusing R2P from the global to the regional and domestic levels; and, finally, we examine the variation of norm effects within the same region across states, investigating in particular how R2P has shaped Chinese and Japanese policy responses respectively.Jochen Prantl would like to acknowledge the generous support for his research by the British Academy (CSG-49402), the ESRC (RES-061-23-0126), and the Zvi Meitar/Vice Chancellor Oxford University Prize in the Social Science

University Administrators’ Visions for the Recovery of International Student Exchange in a Post–COVID-19 World

Objectives: Little is known about how international functions of higher education, such as exchange programmes, can be resumed during recovery from a disruptive global crisis, such as COVID-19. We collected the opinions of administrators of international exchange programmes regarding their plans to resume their exchange programmes in the recovery phase and identified variations in the responses concerning institution type (public vs. private) and the presence or absence of a medical school. Method: We used multiple-choice survey questions in our study, resulting in 180 valid responses. We examined overall patterns using descriptive statistics and institutional uniqueness using Fisher’s exact test. Results: Governing organisations and domestic university networks are expected to initiate the resumption of student exchange programmes. Respondents indicate that they would rely on infection prevention experts at their institutions as sources of information for their decision-making. Public universities would rely more extensively on their staff’s opinions whilst private universities would consult with external experts. Universities with a medical school indicated a greater likelihood of referring to the opinions of experts at their institutions. Implication for Theory and/or Practice: Higher education systems vary across nations. However, extant studies have shown some shared features, and the findings may have implications for higher education institutions internationally. Policy incentives and support may encourage public universities to participate in the global recovery of international education. During global public health infectious crises, institutions without a medical school may require more government support. Conclusions: Institutional variations should be considered to effectively encourage universities to adapt to changing dynamics in the recovery of international education.

Effect of Honeycomb β-TCP Geometrical Structure on Bone Tissue Regeneration in Skull Defect

The effect of the geometric structure of artificial biomaterials on skull regeneration remains unclear. In a previous study, we succeeded in developing honeycomb beta-tricalcium phosphate (beta-TCP), which has through-and-through holes and is able to provide the optimum bone microenvironment for bone tissue regeneration. We demonstrated that beta-TCP with 300-mu m hole diameters induced vigorous bone formation. In the present study, we investigated how differences in hole directions of honeycomb beta-TCP (horizontal or vertical holes) influence bone tissue regeneration in skull defects. Honeycomb beta-TCP with vertical and horizontal holes was loaded with BMP-2 using Matrigel and Collagen gel as carriers, and transplanted into skull bone defect model rats. The results showed that in each four groups (Collagen alone group, Matrigel alone group, Collagen + BMP group and Matrigel + BMP-2), vigorous bone formation was observed on the vertical beta-TCP compared with horizontal beta-TCP. The osteogenic area was larger in the Matrigel groups (with and without BMP-2) than in the Collagen group (with and without BMP-2) in both vertical beta-TCP and horizontal beta-TCP. However, when BMP-2 was added, the bone formation area was not significantly different between the Collagen group and the Matrigel group in the vertical beta-TCP. Histological finding showed that, in vertical honeycomb beta-TCP, new bone formation extended to the upper part of the holes and was observed from the dura side to the periosteum side as added to the inner walls of the holes. Therefore, we can control efficient bone formation by creating a bone microenvironment provided by vertical honeycomb beta-TCP. Vertical honeycomb beta-TCP has the potential to be an excellent biomaterial for bone tissue regeneration in skull defects and is expected to have clinical applications

本稿は、現段階における感染症制御後の大学間学生交流再開の方針、留学形態（対面やオンライン）の見通し、国内での合意形成に関して、学校種類別による比較検討を行い、日本のニューノーマル期の大学間学生交流再開の傾向を明らかにすることを目的としている。大学を代表する立場である担当教職員による179校からの回答を、国公私立別、大学規模別、SGU校別、病院の有無別に分析を行った。その結果、国際交流について大学種類別の特徴が明らかとなった。また、日本の大学は全体的に国内での合意形成を重視しない傾向がある。そのため、今後は、国内の大学同士の情報共有をより活発に行うことが、日本におけるニューノーマル期の大学間学生交流の再開のために重要であることが示唆された。調査報

Determination of specific ion positions of Cr³⁺ and O²- in Cr₂O₃ thin films and their relationship to exchange anisotropy at Co/Cr₂O₃ interfaces

The structures of antiferromagnetic Cr₂O₃(0001) thin films with perpendicular exchange bias were investigated using reflection high-energy electron diffraction, X-ray reflectivity, and synchrotron X-ray diffraction. We mainly investigated the specific ion positions of Cr³⁺ and O²- in the corundum structure and discussed their relationship to the magnetic anisotropy of Cr₂O₃. The Cr₂O₃(0001) thin film grown on a Pt(111) buffer layer exhibited a perpendicular exchange anisotropy density of 0.42 mJ/m², in which the Cr³⁺ position is the primary factor in the enhancement of magnetic anisotropy due to dipolar-interaction. In contrast, the single-crystalline Cr₂O₃(0001) film grown on a α-Al₂O₃(0001) substrate featured a low exchange magnetic anisotropy of 0.098 mJ/m². In this film, the Cr³⁺ position parameter is an insignificant factor, leading to low magnetic anisotropy. The O²- ion position also differs between the two types of films, which can affect both the magnetic anisotropy energy originating from fine structures and the magneto-electric properties of Cr₂O₃.Yu Shiratsuchi, Yuuta Nakano, Nobuhito Inami, Tetsuro Ueno, Kanta Ono, Reiji Kumai, Ryoko Sagayama, and Ryoichi Nakatani, Journal of Applied Physics 123, 103903 (2018); https://doi.org/10.1063/1.5020620
