黄河岸边菜花香

Advancing through the expansive land alongside the south bank of the Yellow River,the snow-covered lofty mountains in the distance seemed to bring a slight,jarring chill as we moved forward along the gravel road.Sopa took this opportunity to point out the cultivated land alongside both the right and left flanks of the road to me.     

检疫、种族与租界政治——1910年上海鼠疫病例发现后的华洋冲突

1910年10月初,上海公共租界发现鼠疫病例,由于"不卫生"的华人被视为疾病蔓延的温床,外人市政当局采取了带有明显种族偏见的检疫措施,华洋关系骤然紧张,引发了多起华人下层民众的街头骚动。为了防止事态进一步恶化,华人精英提出自主检疫的主张,与外人进行协调和谈判,同时努力说服普通民众和平抗争,迫使外人最终不得不做出让步。在此后的检疫和救治过程中,华人精英一丝不苟,普通民众主动配合,不但让外人刮目相看,且也使华人增加了参与租界政治的信心。联系事态的连锁反应和后续发展,此次华人争取自主检疫的抗争,可视为推动英帝国威权在上海租界渐次崩衰的重要一环。     

新疆阿勒泰地区早期铁器时代铜器的科学分析研究

阿勒泰地区位于新疆的最北端,与欧亚草原之间存在丰富的文化交流,而冶金技术的发展与人类文明紧密相关,为探究新疆阿勒泰地区的冶金发展情况,选取9件草原游牧文化的代表性器物——铜鍑和马具,使用金相显微镜、扫描电子显微镜和X射线能谱仪及双通道电感耦合等离子体发射光谱仪,对16个样品进行金相组织分析和成分分析,并探讨其制作技术特征。研究发现阿勒泰地区的早期铁器时代铜器普遍采用范铸工艺,其成分主要为红铜、砷铜、铅砷青铜。该分析结果为研究新疆阿勒泰地区的冶金发展提供了重要参考。     

Pierre Marie: gifted intellect,poor timing and unchecked emotionality

Pierre Marie was a prominent member of the French neurological world of the early twentieth century. Having been trained by the celebrated physician, J-M Charcot, Marie remained influenced by his teacher throughout his career. Because of this influence, his career can be logically divided into three phases: first, the early years under the direct mentorship of Charcot (1878-1893); secondly, the aftermath of Charcot's death when Marie left his teacher's institution, the Salpêtrière hospital and established himself at the Bicêtre hospital in southern Paris (1893-1918); and finally, Marie's return to the Salpêtrière to assume the original Charcot chaired professorship, albeit as an aged man (1918-1925). This essay examines Marie's career with an emphasis on documentation of the combined attributes of a gifted intellect as well as a heated emotionality. In the context of his time, these elements prompted Marie to enter into controversies and medico-political battles that advanced neurological knowledge, but likely disadvantaged him in his career successes.     

Low-Fired Earthenwares in the African Diaspora: Problems and Prospects

Local earthenware associated with enslaved African populations in the Americas, variously called Colono-Ware, Afro-Caribbean Ware. Yabbas, and Criollo ware, has received considerable attention from researchers. What unifies this disparate group of ceramics is not method of manufacture, design and decoration, or even form and function but the association or potential association with African diaspora populations. The ceramics incorporate some skills and techniques possibly brought by African potters to the Americas, as well as skills reflecting European and Native American traditions, and local adaptations in form, function, and manufacture. Analogies linking African ceramic traditions to American industries have at times been employed uncritically and have relied on generalized characteristics to infer overly specific meanings. With particular reference to low-fired earthenwares from Jamaica, this paper examines the historical and cultural context of these ceramics and the methodological and theoretical problems faced in their interpretation.     

SO2与水分综合影响下的云冈石窟砂岩劣化研究

气体污染物SO₂是造成云冈石窟文物本体劣化的重要因素之一。为厘清SO₂与水分耦合作用下的云冈砂岩劣化规律，开展不同SO₂浓度、相对湿度以及降水条件下的室内模拟风化试验，测定试样质量、表面特征和化学成分变化。结果表明：SO₂易与砂岩中的碳酸盐矿物(如方解石)和长石发生化学反应，产物包括CaSO₄·2H₂O、MgSO₄·7H₂O和高岭石等，且随着相对湿度增加，反应程度增大，造成试样的质量、色差值、可溶盐含量上升及硅铝比下降；液态水的参与能显著加快SO₂与砂岩的相互作用过程，不但增加了各项指标的变化幅度，还加大了SO₂入侵深度。研究成果可为砂岩质文物的科学认知和预防性保护提供参考。     

Sharpening Advocacy Coalitions

The concept of “advocacy coalitions” is the bedrock of the Advocacy Coalition Framework (ACF), one of the most established and successful approaches for understanding policy processes across the globe. This article revisits and sharpens the conceptual definition of advocacy coalitions. We summarize the lessons from its theoretical emphases under the ACF and specify its five attributes (policy actors, shared beliefs, coordination, resources, and stability). Through this specification, we identify the ideal coalition type and several coalition subtypes. We then clarify and make a distinction between how we think about coalitions as a concept and how we approach coalitions empirically. This article sharpens the lens for describing and explaining coalitions toward better observations, theorizing, and measurements. It ends with next steps for further deepening and broadening knowledge about advocacy coalitions.
