Micro-CT-assisted determination of the shattering and non-shattering phenotypes of charred rice spikelet bases from archaeological sites: a new methodological approach

The selection of a non-shattering phenotype is a pivotal change in the process of rice domestication. However, current research is heavily restricted by the preservation conditions of macro-plant remains in early and middle Neolithic sites, as very limited well-preserved rice spikelet bases could be retrieved. We present a non-destructive method based on micro-computed tomographic (CT) scanning, which could provide detailed visualization of the internal structures of charred spikelet bases and efficiently discriminate the shattering and non-shattering phenotypes of rice spikelet bases according to the abundance of fusiform echinate phytoliths. It could be widely applied in different contexts, especially those poorly preserved specimens and tempers in pottery sherds, greatly improving our knowledge of rice domestication.     

Rediscovering regional science: Positioning the field's evolving location in science and society

This study aims to provide a comprehensive examination of the evolution of regional science, a scholarly domain in the social sciences that applies analytical and quantitative approaches and methods to understand and address urban, rural, or regional problems. We conducted a bibliometric analysis of 8509 articles published in six regional science flagship journals (including the Journal of Regional Science, Annals of Regional Science, Regional Science and Urban Economics, Papers in Regional Science, Regional Science Policy and Practice, and International Regional Science Review) from 1958 to 2021. The analysis presents an objective data-driven and unprecedented visualization of the field's intellectual, social, and conceptual structure and trends from the beginning to the present. It also provides a rich portrayal of the epistemology of regional science and illuminates matters related to regional science education and training. We find that regional science has moved well beyond its origins, shifting away from a heavy focus on theory and abstraction to modeling/simulation, empirical analysis, and policy research. We also find that there has been increasing attention to “people” in regions and the spatial characteristics of social problems, and some important shifts in the regional science community itself, particularly in terms of patterns of collaboration and the geography of scholarship. The findings of this paper provide implications for future directions of research and education for regional science.     

英语世界的胡适研究

本文广泛收集和整理了英语世界的胡适研究成果,仔细阅读、推敲其中有代表性的著作,细致总结和概括出英语世界胡适研究成果的基本情况,划分和厘定了英语世界胡适研究史的不同发展阶段,以求在一个宏大的框架下更好地把握英语世界胡适研究的历史、现状及其走向。笔者发现自20世纪二三十年代起,英语世界就出现了零星的胡适传记和研究著作。五六十年代以来,与胡适相关的研究开始大量涌现:英语世界的研究者或在有关中国文学、哲学、史学、教育、外交、宗教等方面的著作中列专章,或者以专著、学术论文的形式对胡适进行研究,其中值得注意的是以胡适为专题的20多部博、硕士论文和专著。     

论木鱼书《花笺记》的伦理教化思想

中国传统文化强调儒道互补,而以儒家思想为主。儒家思想又富于浓厚的道德色彩,信奉的是伦理中心主义,因此伴随着儒家思想影响力的不断扩大,中国文化中一切精神层面的东西都蒙上了伦理的色彩,文学当然也不例外。以中国古代较早传入西方并引起很大反响的文学作品为例,如《好逑传》,之所以能得到歌德的好评,就是因为它以才子佳人的故事演绎了儒家“发乎情而止乎礼”的思想,富有东方道德的浪漫色彩。而《赵氏孤儿》除了与西方文学相类似的“复仇”主题外,其中蕴含的“忠”、“义”观念也成为西方人了解中国文化的一面镜子。我们因为深深浸淫于儒…

波斯早期犹大政策重探

传统的学术研究往往认为,居鲁士圆柱铭文和希伯莱《圣经》的有关记载可以相互印证,具有历史真实性;两者反映出居鲁士大帝鼓励被掳的犹大人回归故土,并全力支持他们重建圣殿。本文重新分析了铭文文本,指出它和犹大人回归并无直接关系。在此基础上解读《圣经》记载的波斯诏令,本文认为它们缺乏历史真实性,进而结合历史背景,提出波斯帝国早期(公元前539年到前5世纪中期)并未明确鼓励和支持犹大人的回归和重建圣殿。波斯所要求的只是犹大的政治稳定与缴纳赋税,其有限的宽容完全建立在自身利益诉求的基础上。
