The notion of post-Chineseness is enlisted to analyze Vietnamese Sinology as a comparative agenda. Post-Chineseness refers to the cultural preparation and the political process of mutual acknowledgement among those who consider one another sharing (some kind of) Chineseness, practically defined according to the context and its trajectories, at each time and each site. Chineseness can thus have various, if not entirely irrelevant, meanings. Vietnamese Sinologists have relied on different kinds of post-Chineseness to make sense of their relationship with the encountered Chinese to select and determine the mode of self-understanding, the purpose and a strategy to reconnect, and the normative criterion to assess and manage the relationship. Chinese Vietnamese are significantly less numerous than Chinese Malaysian, Thai, and Indonesians. However, the history of Vietnam is considerably closer to China than are those of Korea and Japan, in terms of length of merger. The post-Chineseness of Vietnamese scholarship therefore complicates its role-identity vis-à-vis China, intellectually as well as practically.  相似文献

ABSTRACT

Historic Japanese textiles from over 1000 years ago generally show marked deterioration and only very rare examples show their original forms and much information about textile reproduction has been lost. The replication of textile braids lacks systematic methodology and is still being practiced by only few individual braiding experts. The recreation of original braids as close as possible to original braids is a part of Japan’s intangible cultural heritage. The aim of this study is to clarify the decision-making procedure through which the braiding experts can decipher the original braiding structures. As a preliminary study of this project, interviews of a braid researcher and a replicating expert, Makiko Tada were performed regarding her working practices. It is important to clarify the braiding parameters for structural analysis such as the number of transits and the balance of ridges, and it became clear that the orientation of multiple colored threads plays an important role. The expert’s replicate works were also analyzed using a text-mining statistical technique to clarify the relationship of braiding parameters. The relationship between each braiding parameter and production method such as loop manipulation and Taka-dai became clear. As a result, the process of deciphering the original braid structure has been compiled in simplified workflows, which could contribute to the standardization and improvement in efficiency of replication of cultural property braids.  相似文献

Problem-based learning (PBL) emerged during the 1970s in response to demands for active learning methods capable of developing transferable knowledge and skills in the training of doctors. Over succeeding decades, PBL was gradually adopted in other fields of education. This systematic review aimed to identify key streams of theory and empirical research that have emerged over time in PBL research and practice. The review sourced 12,036 Scopus-indexed documents published between 1974 and 2019. Science mapping was used to reveal the ‘intellectual structure’ or key research themes that have evolved in this literature over the past 45 years. The science mapping tool used in this review was author co-citation analysis conducted in VOSviewer software. Author co-citation analysis identified three schools of thought that together describe the intellectual structure of the PBL knowledge base: Design of PBL Curriculum and Instruction; PBL Effectiveness; Theory and Practice in Active Learning. In addition to portraying the intellectual structure of the literature as a whole, the review also conducted longitudinal analyses aimed at highlighting structural changes in this field over time. These analyses found that although the size and impact of schools of thought associated with Design of PBL Curriculum and Instruction and PBL Effectiveness increased over time, they remained stable in terms of theoretical foci. However, the Active Learning school evolved from a small school of authors associated with Cognitive Learning Theories prior to 2000 into the largest school of thought during the most recent decades. These findings both reaffirm the theoretical underpinnings of the PBL knowledge base and highlight its increasing integration with other forms of active learning.  相似文献

液滴撞击固体壁面现象常见于动力机械、喷雾冷却和薄膜材料沉积制备等工业生产中。将石墨烯和碳纳米管作为分散颗粒,应用超声波分散技术制备均匀性与稳定性良好的树脂基纳米流体。利用高速摄像技术,研究纳米流体液滴撞击固体壁面的动力学行为。基于有限元法,通过修正的幂律黏度模型耦合纳米流体的剪切变稀特性,采用水平集方法捕捉相界面的移动,建立纳米流体液滴撞击固体壁面的数值模型。模拟结果与实验结果较好一致,验证了数值模型的正确性与准确性。研究发现实验配制的纳米流体表现出非牛顿剪切变稀特性,纳米颗粒的加入抑制了液滴撞击固体壁面过程中的铺展和回缩行为。随着幂律指数m的减小,液滴撞击固体壁面后的铺展范围变大。随着表面张力的增大,液滴的无量纲直径在铺展阶段无明显变化,但在回缩阶段逐渐减小。  相似文献

以海阳大秧歌中的民俗武术活动“斗秧歌”仪式为个案,运用田野调查等方法,从民俗学视角对“斗秧歌”的过程及民俗语境进行分析。认为:海阳大秧歌吸收了军事武术中的兵法谋略与民间武术技术动作,族群生存斗争与比武较技是“斗秧歌”吸收武术元素的重要动因,其逻辑形式表现为礼法约束下由“文斗”到“武斗”的递进,“文斗”体现兵法谋略智慧,武术是“武斗”的主要支撑力量。“斗秧歌”受到礼法约束,以强化乡间社会秩序的稳定,反映了中国传统社会治理中的礼法并施思想。剖析其民俗语境发现,“斗秧歌”是族群生存抗争的仪式手段、护卫生存环境的民间演习、展示个人魅力的艺术舞台,也是地域武术传播的民俗载体。武术与“斗秧歌”之间的融合互动关系,显示武术与民俗活动深厚的历史渊源及武术具有的多元价值属性。  相似文献

我国作为大体沿袭大陆法系立法的国家,在信托法与物权法的衔接上存在着物权请求权的唯一性与对受益人保护的衡平这二者之间的矛盾。其解决方式就是确定信托财产上物权请求权的归属以及给予非信托财产所有权人以物权的保护方式。  相似文献
