东北地区城乡结构的演变机理与统筹发展

由于历史、文化、政治、经济和地理等方面的原因,东北地区的城乡二元结构是我国最突出、最奇特的地区。本文简要回顾了计划经济时期的二元城乡结构,然后从经济结构、居民收入与消费、城乡规模结构和社会发展水平等方面深入分析了改革开放后东北地区城乡结构的演变过程与动力机制。最后从区域经济结构调整、城乡发展战略和制度创新等方面,提出了促进城乡统筹发展的策略。     

中国海外劳务移民的发展变迁与管理保护——以移民工人维权和争议处理为中心的分析

论文从移民工人维权和劳动争议处理这一新视角,较为系统地分析中国海外劳务移民的历史发展与管理体制,深入剖析中国劳务移民管理的法律政策框架及维权和争议处理机制,比较借鉴劳务移民典型国家的经验做法,并对实现中国劳务移民有效管理的对策与措施,提出了四点建议:一是完善相关国内立法,构建多边合作协议框架;二是确立劳动行政部门主管,建立多部门政策协调机制;三是强化政府公共服务职能,加强海外劳务移民监管;四是加大工会组建、培训和维权力度,充分发挥工会组织的作用。     

两种主张的较量与战后德国经济发展

战后德国经济是在左和右,即主张国家干预和自由经济,这两股社会和政治势力交互作用下发展起来的。前者主由社民党体现,后者由基民彤社民盟主张。最初这两股势力形成了有效互补,使得德国社会和经济进入高发展期,后来由于这两股势力彼此抗衡过度,失落了有效互补,社会体制失去活力,经济和社会进入发展低迷期。如今,德国经济一直挣扎在这样的发展困境中。     

Mobility-driven cultural transmission along the forager-collector continuum

Hunter-gatherers mobility regimes are often treated as discrete adaptive strategies. Here we present a model of forager mobility which treats collectors and foragers as two ends of a continuous spectrum. We show that a mobility regime can be situated along this spectrum by specifying the number of foraging moves a group makes before returning to its home base. The model allows us to explore the behavioural space between forager (i.e. residential mobility) and collector (logistical mobility) adaptations. We discuss the heuristic value of the model by showing how it can be used to make testable predictions about the impact of mobility strategies on archaeological measures such as occupation intensity and raw-material transportation distance. We then use the model to investigate the impact of mobility on rates of cultural transmission. We show that mobility-driven cultural transmission may be equivalent to a Poisson process and that the time it takes for a cultural behaviour to be transmitted between two mobile groups is optimized when the mobility regime is somewhere between pure forager and pure collectors adaptations. In addition, we find that rates of cultural transmission decline in a very regular way, as the inverse of the square root of the number of moves made before returning to home base. This suggests that there is a mechanistic connection between the mean-squared displacement of hunter-gatherers in space and the transmission of cultural traits.     

唐代周边国家和地区的“遣唐生”与唐文化的传播

唐朝是中国封建社会发展的巅峰时期,是举世瞩目的封建王朝。唐代发达的经济和文化,以及对外开放政策,吸引了亚洲邻国和边疆少数民族政权竞相派遣遣唐生前来学习。本文从唐代周边国家和地区派遣遣唐生的规模、遣唐生教育形式、体制等方面,探讨唐代遣唐生教育发达的原因,研究遣唐生教育在唐文化传播中的作用。

De la carte au territoire: Portée et usages des outils cartographiques au sein de la Première Nation des Pekuakamiulnuatsh Entrevue avec Michel Nepton,membre de la Première Nation des Pekuakamiulnuatsh et conseiller en aménagement du territoire

From map to territory: Scope and uses of mapping tools within the Pekuakamiulnuatsh First Nation Interview with Michel Nepton, member of the Pekuakamiulnuatsh First Nation and land use and planning advisor While the mapping of Indigenous territories has long been at the heart of land-grabbing strategies orchestrated by the colonial powers, these tools are now largely mobilized by Indigenous communities through the processes of claiming, negotiation, and affirmation. The specific context of land claiming in Canada has also contributed in a significant way to the increasing use of these tools by communities seeking to demonstrate their historical occupation of land. In any case, the translation of Indigenous knowledge into exogenous geographical language remains subject to criticism and caution, particularly by the tenants of critical mapping. In order to shed new light on these issues, the following interview was conducted with the land use and planning advisor Michel Nepton, working in the Pekuakamiulnuatsh Takuhikan Land rights and protection board (Council of the Pekuakamiulnuatsh First Nation, Mashteuiatsh). Bringing forward his experience and use of mapping tools within his professional practice, his thoughts reveal the role and scope they have in the specific context of his community.     

Managing mass migration after the war: The case of Sarajevo’s unification in 1996

This study analyses the immediate consequences of the transition from war to peace in Sarajevo, the capital city of Bosnia–Herzegovina. It focuses on the management of a tense security situation related to the postwar unification of the city, which was divided between warring belligerents during the Bosnian conflict. Firstly, it shows how ethno-nationalist leaders' visions and practices of ethnic homogenization continued after the end of the war as the result of the Dayton Peace Agreement (DPA). The principal tool of their postwar ‘ethnic engineering’ endeavour was to maintain and generate an atmosphere of fear, based on anticipated discrimination, maltreatment, and persecution from former belligerents. Secondly, this study explores how experienced wartime violence and related transformations in personal identities and social positioning activated latent boundaries between groups and made individuals more disposed to forms of group identification. As a result, the mass migration of people out and into Sarajevo strengthened the grip over the territories assigned to former adversaries by the DPA. This article argues that studying the mutually constitutive roles of the elite's ethnic engineering as well as ordinary people's experiences is necessary to understand how organised wartime violence transformed into structural, institutional, and other less visible forms during the postwar period. Ethno-nationalists’ discourses and points of view demonstrate how wartime violence channelled the postwar lives of Sarajevo's residents into a desired spatio-political arrangement.     

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。
