晚清时期南洋地区中华商会的角色定位及其实践

论文聚焦于晚清南洋各埠中华商会的创办及其在保障当地华人华商权益、增进海内外同胞沟通与交流等方面所发挥的作用,从章程文书和案例两个视角剖析南洋中华商会的角色定位。20世纪初,清政府倡导创办商会,南洋各埠华商积极响应。由于清政府在海外的护侨保侨作用有限,南洋中华商会在近代海外华人社会中扮演着多重角色。它不仅是商业联合组织,更是维护海外华侨权益、增进海内外同胞交流的重要支柱。早期中华商会的一系列努力奠定了其在海外华侨社会中的影响与地位,并延续至今。     

从近20年《历史地理学杂志》的相关文章看西方历史动物地理研究的新动向与启示

东西方历史学、地理学的不同特点及发展方向,使双方历史动物地理的研究也有所不同。通过对2000—2018年英国《历史地理学杂志》所刊历史动物地理相关文章的分析,可以发现近年来西方历史动物地理有议题与方法的多样化、关注与人类密切接触的常见动物、关注中小尺度具体空间下的动物这三个研究动向。在此基础上,相关研究成果不仅填补了历史研究中的一些空白,更对一些历史问题提出了新解,在推动史学研究的同时,也进一步突破了人类中心主义思想。这些研究长处值得我国历史动物地理研究在坚持自身优势的基础上加以借鉴。     

环南海区域跨境航空网络空间结构演化

本研究收集2000、2010、2018年环南海区域各国家/地区间国际机场的跨境客运、货运航线和航班数目,探究近20年该区域跨境航空客运和货运网络的整体结构与空间格局演化特征,并综合客运和货运网络分析枢纽机场体系演化。研究发现：①该区域跨境航空网络的整体结构具有覆盖范围扩大、“小世界”效应明显和“无标度”特征显著的特点,但客、货运网络的演化存在差异。②该区域跨境航空客运网络具有明显的轴—辐组织结构特征,并呈现“多核心化”的演化趋势,而货运网络中以香港、新加坡为枢纽的轴—辐组织结构与局部性的“点—点”航空货运联系并存,尚未形成全局性的轴—辐组织结构。③该区域的区域客、货运枢纽机场发展呈现综合化、专业化趋势,香港（HKG）和新加坡（SIN）长期以来保持优势地位。     

土质文物盐害中硫酸钠的研究——从微观到宏观

土遗址和壁画遗址可溶盐主要为NaCl和Na_2SO_4,其中Na_2SO_4是破坏程度最严重的盐。一般认为,硫酸钠只有在温度、湿度变化时才不稳定,才发生得失结晶水引起的晶型及体积变化。为研究土质文物盐害的形成机制及内在原因,调研了全国几处典型土遗址和壁画遗址的盐害状况并取样分析。分析发现:1)土遗址和壁画遗址中硫酸钠的形貌、结构是动态变化的(无论在任何极端干燥环境甚至真空条件下);2)环境因素如温度、相对湿度的变化只是加剧上述变化进程。硫酸钠结晶析出时,其体积膨胀约4倍。这一系列的过程,深刻影响着硫酸钠的相变复杂性和对依存土质文物本体的破坏性。本工作从微观和宏观两个层面探讨了这些发现,并通过不同盐分(不同浓度氯化钠、硫酸钠)侵蚀破坏模拟试验、不同温度条件下模拟试验、不同相对湿度下模拟试验,从宏观层面印证了上述微观机制在土遗址和壁画遗址本体的外在表现。本研究发现土遗址中硫酸钠的形貌、结构是动态变化的,该工作弥补了以往研究和认识上的局限。本研究将对阻止、延缓及预测土质文物盐害的发生、发展提供科学参考。     

《馆藏文物防震规范》关键技术——防震安全设计研究

《馆藏文物防震规范》WW/T 0069-2015,基于馆藏文物防震安全提出馆舍、展陈和文物全系统防震安全理念、设计方法和具体措施。本研究针对馆藏文物防震设计方法、适用范围、展柜及文物安全性判别等关键技术问题展开研究。首先,提出了"地震波+馆舍+展柜+文物"的全过程全系统防震设计理念;其次,针对浮放展柜及文物,进行地震作用下安全性分析研究;第三,与Getty博物馆研究成果对比,验证本研究理论的正确性与可靠性。分析得出:文物防震安全与文物高宽比、支撑接触面摩擦系数、安放处加速度峰值等因素有关;引入了抗滑动安全系数和抗倾覆安全系数进行设计,可充分保证文物安全性。     

The first fossil record of Nandeva Wiedenbrug,Reiss & Fittkau (Diptera: Chironomidae) in early Eocene Fushun amber from China

Gi?ka, W., Zakrzewska, M., Baranov, V., Wang, B. &; Stebner, F., May 2016. The first fossil record of Nandeva Wiedenbrug, Reiss &; Fittkau (Diptera: Chironomidae) in early Eocene Fushun amber from China. Alcheringa 40, xxx–xxx. ISSN 0311-5518

The first fossil representative of the extant chironomid genus Nandeva Wiedenbrug, Reiss &; Fittkau, 1998 Wiedenbrug, S., Reiss, F. &; Fittkau, E.J., 1998. Nandeva, gen. nov., a new genus of Chironomini (Insecta, Diptera, Chironomidae). Spixiana 21, 59–68. [Google Scholar] is described based on a specimen found in early Eocene (50–53 Ma) Fushun amber from China. The adult male of Nandeva pudens sp. nov. has the long RM vein as a continuation of M and R₄₊₅, the bare squama, the strongly reduced anal area of the wing and hypopygial characters typical of extant species of the genus. Following the systematic concept based on adult male morphology and characters examinable in fossil specimens, we present N. pudens as a possible member of the Tanytarsini, arguing that Nandeva is part of this tribe or a possible sister group to the tribe. This is the first record of Nandeva from the Palaearctic region.

New Chinese psocids from Eocene Fushun amber (Insecta: Psocodea)

Zhang, Q., Nel, A., Azar, D. & Wang, B. April 2016. New Chinese psocids from Eocene Fushun amber (Insecta: Psocodea). Alcheringa 40, xxx–xxx. ISSN 0311-5518

Two new Psocodea, Sinopsyllipsocus fushunensis gen. et sp. nov. and Eotriplocania sinica gen. et sp. nov., are described from Eocene amber of Fushun City, China. They are distinctly different from all known Psocodea from Fushun amber in their three-segmented tarsi. Sinopsyllipsocus fushunensis is the second unequivocal fossil of Psyllipsocidae. Eotriplocania sinica is the first Asiatic and oldest representative of the Neotropical family Ptiloneuridae, and reveals a formerly global distribution of the family. The discovery of these two families in Eocene Fushun amber suggests a rather warm palaeoclimate for the Fushun amber locality.

The oldest silken fungus beetle from the Early Cretaceous of southern China (Coleoptera: Cryptophagidae: Atomariinae)

Cai, C.-y. & Wang, B., 2013. The oldest silken fungus beetle from the Early Cretaceous of southern China (Coleoptera: Cryptophagidae: Atomariinae). Alcheringa 37, 1–4. ISSN 0311-5518

Atomaria cretacea sp. nov., a new silken fungus beetle, is described and figured based on an impression fossil from the Lower Cretaceous Shixi Formation at a locality near Qingxi Town, Jiangxi Province, southern China. The new species can be referred to the extant family Cryptophagidae as supported by the tiny body size, the clubbed antenna with dilated antennomere 1, closely spaced antennal insertions, and abdominal ventrite 1 being longer than the remaining ventrites. It is placed in the extant subfamily Atomariinae based on the presence of a frontoclypeal suture and the absence of gular sutures; and tentatively in Atomaria based on its body size, sub-parallel body shape, and the presence of a frontoclypeal suture.

浙江杭州出土《僧璨砖塔铭》刊刻年代献疑

出土于浙江杭州的《僧璨砖塔铭》,被学界认为是研究中国佛教禅宗传灯体系的一件重要资料。笔者通过大量文献资料的研究,尤其是对唐代相关石刻的分析对比,认为该塔铭刊刻年代并非自题的所谓"大隋开皇十二年",很可能是唐代禅宗兴起之后禅宗信徒们伪造出的一件反映禅宗传灯世系的实物,刊刻时间不早于九世纪后期。
