中国乡村城市化研究:起源、概念、进展与展望

本文回顾了20世纪80年代以来我国乡村城市化研究的起源,对乡村城市化和自下而上城市化两个概念进行了辨析,对近20年来乡村城市化研究的内容、进展以及存在的主要问题进行了评述,并对未来乡村城市化研究的方向作出了展望。     

论张学良与“西北国防政府”计划

张学良自成局面的设想和中共先行建立地区性国防政府的策略 ,是促成“西北国防政府”计划产生之两大要素。但在该计划的实施步骤及是否反蒋、如何打通苏联等问题上 ,张与中共间存在着某些潜在分歧 ,加之中共的政策由反蒋抗日急剧转向逼蒋抗日 ,打通苏联亦未能成功 ,从而导致该计划终归流产     

博物馆文物的防震保护研究（一）——传统抗震措施与现代隔震技术

通过对博物馆内物浮放物体的地震危害性分析,指出了物防震的一些主要问题。归纳总结了馆藏物的传统抗震措施。阐述了现代隔震技术的发展、研究现状以及隔震装置在物防震工作中的应用情况。同时给出了博物馆物防震保护的设计方案。     

《张家山汉墓竹简·二年律令》中诸律的制作年代试探

对《二年律令》中《户律》、《赐律》、《秩律》、《置后律》及《收律》等的制作年代进行考证,证明《二年律令》中的诸律并非制作于同一时期,从而为正确运用《二年律令》提供了可供参考之处。     

温敏型淀粉酶产生菌的分离、分子生物学鉴定及特性研究

我国博物馆里有许多珍贵的书画文物,然而这些书画文物由于材质易损,年代久远,在修复过程中,揭裱是一个难题。揭裱过程中,书画与背纸之间的浆糊是导致书画文物揭裱困难的主要障碍。利用淀粉酶可以有效分解浆糊淀粉,提高揭裱效率,但揭裱后残留在文物上的淀粉酶会影响后续的重新装裱,因此开发温度敏感型淀粉酶有助于揭裱后的重新装裱。本研究取样于东北寒地土壤,并通过分离、筛选得到了一株产温敏型淀粉酶菌株,且命名为BWL1025。通过分子生物学方法,确定了该菌株为枯草芽孢杆菌(Bacillus subtilis)。并且通过DNS法测定目标菌株所产淀粉酶的最适pH及其稳定性、最适酶活温度、最低失活温度和最短失活时间。实验结果表明,在40℃时,酶活达到最高值,为0.839 IU/mL;在60℃时,处理25 min后,酶活基本消失。此外,本研究对该菌株的发酵条件进行优化,发现以木糖和酵母粉为最佳碳源和氮源时,酶活最高达到1.63 IU/mL。本研究结果为书画文物的修复提供了新型的温敏型淀粉酶来源。     

故宫博物院藏宋代铜凤凰的修复保护与研究

文物修复保护及研究是一项涵盖多学科、多因素的系统性工作,不同文物中所包含的历史信息、文化价值和病害情况等都有其独特性。对文物的观察和研究,既能够发现、研究其中有价值的问题,又能够决定如何具体开展文物修复保护工作。本文以故宫博物院藏的一件宋代铜凤凰修复保护及研究工作为例,以时间发展和问题递进两个方面为顺序,对铜凤凰进行了信息调查、元素成分、形态结构、制作工艺等方面的综合研究,科学地、具体地、整体地分析在此项工作过程中所遇到的问题,根据实际情况提出与之相适应的解决方案并加以实施,对问题的发现过程与形成因素给出尽可能详细的解释,直观呈现对这件文物完整的修复保护及研究。在整个工作的过程中,思考使用问题导向思维作为文物修复保护中开展工作的底层逻辑,使所做工作都尽可能做到知其然也知其所以然。     

国外对零售业及其附生——衍生的营业性娱乐场所的空间关系研究

零售业及其附生-衍生的营业性娱乐场所是城市居民日常生活(闲暇娱乐)行为的四大场所之一,零售业中附生-衍生的娱乐场所的类型、结构与空间模式是揭示城市社会-生活空间质量的重要方面,本文从城市社会地理学以及人类文化生态学等多学科的研究角度,分析与总结国外学者对零售业及其附生-衍生的营业性娱乐场所的研究现状、内容以及其在城市中的空间作用与(社会)空间关系。     

Alfred Walter Campbell’s return to Australia

Alfred Walter Campbell (1868–1937) established the basic cytoarchitectonic structure of the human brain while he was working as a pathologist at the Rainhill Lunatic Asylum near Liverpool in the United Kingdom. He returned to Australia in 1905 and continued doing research while establishing a neurological practice. His research over the next 17 years focused on four topics: (a) localisation in the cerebellum, (b) the neuroses and psychoses in war, (c) localisation in the cerebral cortex of the gorilla, and (d) the causes and pathology of the mysterious Australian “X” Disease (later known as Murray Valley encephalitis). In this article, I elaborate on his research in these areas, which provided evidence (a) against Louis Bolk’s thesis that variation in the size of the cerebellar cortex reflected variation in the amount of cortex controlling various groups of muscle, (b) against the view that the neuroses and psychoses in war were different from those in civilian life, (c) for a parcelation of the cortex of the gorilla brain that supported his earlier findings in the higher apes, and (d) on the cause and pathophysiology of Australian “X” disease. Much of this research was overlooked, but it remains of considerable value and historical significance.     

The estimation of size in sardines (Sardina pilchardus) from amphorae in a wreck at Randello,Sicily

Large quantities of sardine (Sardina pilchardus) bones from amphorae in a wreck at Randello, Sicily, were examined. Methods of estimation of size of the fish represented using the lower jaw bone (dentary) and the gill cover (operculum) by comparison with those of modern fish are given. Both methods give comparable results; from dentaries 108–171 mm and from opercular bones 116–176 mm total length.     

From folklore to patriotic and protest songs: Music,youth, and Basque identity during the 1960s

Taking a bottom‐up approach to the study of nationalism, the following pages constitute an attempt to shed light on the role singing played for a young generation of Basques who actively participated in the process of construction of Basque collective identity during the cultural revival movement of the 1960s. In doing so, this article aims at showing the fundamental role of active audiences, as well as their changing political and social context, in conforming the meaning of “Basque songs” as means to promote Basque nationalism and sustain opposition to the Franco regime. The study of the production, reception, and reinterpretation of Basque music during the cultural revival of the 1960s presented here intends to emphasize the interest of focusing on how ordinary people contribute to the recreation of the nation through their appropriation and interpretation of cultural symbols and practices.
