胡人发型:中古“剪头胡雏”艺术形象试解

古人发型是文化界长期关注的一个重要现象。发型不仅是时代的特征与时尚的符号,也是各个族群的辨识标志。从北朝到隋唐的中古社会,"剪头胡雏"的文物图像屡屡出现,一般来说,此类胡人形象是剪发而不是束发,在当时以"高髻为尚"的社会习俗中,"剪头胡雏"发型是有着"阶级感"的存在,是有关底层胡人的直观艺术产物。也说明当时入华胡人还没有彻底"汉化",仍然保留着本族群的发型特征。该发式是胡人与汉人的区别,也是其身份归属的象征。     

明清丝绸之路哈密—吐鲁番段“沙尔湖路”研究

明清丝绸之路哈密—吐鲁番段存在一条自哈密西南沙尔湖转西北至鄯善进而抵达吐鲁番的“沙尔湖路”,它与“黑风川道”“小南路”等传统路线均不同。利用《蒙古山水地图》等文献,可对沙尔湖路具体行经进行考证复原。该路沿线地形平坦,有泉水与植被,在明廷与吐鲁番、清廷与准噶尔在哈密的政治和军事对峙阶段曾广泛使用,后因泉湖干涸、气候炎热而中断。     

HISTORY MAKING AND ETHICS—AN INTEGRAL RELATIONSHIP?

In this review essay, I examine the arguments made by Marnie Hughes-Warrington, with Anne Martin, in Big and Little Histories: Sizing Up Ethics in Historiography. While I find much to praise in this history, I also ask critical questions about the impact of non-Western ethics on historical writing, the role of ethics in historical writing generally, the need to further investigate the everyday lifeworlds of history makers in order to fully understand their ethical dispositions, and the relationship between the ethics of history making and engaged forms of historical writing. I conclude this review essay by offering some reflections on the interrelationship between history and memory and the ethics involved in both.     

Evidence on economies of scale in local public service provision: A meta-analysis

The standard theory of optimal jurisdictional size hinges on the existence of economies of scale in the provision of local public goods and services. However, despite its relevance for forced local amalgamation programs and related policies, the empirical evidence on the existence of such economies of scale remains elusive. The main goal of this paper is to produce an updated and comprehensive quantitative review of the existence of economies of scale in the provision of local public goods using a meta-analysis approach to systematize the wide range of empirical approaches and modeling frameworks found in the previous literature. Our analysis confirms the presence of moderately increasing to constant returns to scale in the provision of local services with no reduction in the average costs of production in the delivery of most local public services beyond a certain, modest jurisdictional size, which many studies have estimated at 10,000 residents. Also, the potential for economies of scale differs at least across three traditional services: education, water and sanitation, and garbage collection, being highest for education and lowest for garbage collection. Our analysis also offers guidelines for future empirical research in this area. Physical output and production cost data should be used, together with translog specifications for the modeling of cost functions. Last, we find evidence that the determinants of output cost elasticity include bidirectional publication bias and population density but do not include the presence or absence of modern “lean” production technologies or the (perceived) capital intensity of the sector, contrary to conventional wisdom. These findings have significant policy implications for countries considering jurisdictional consolidation programs.     

Pram mobilities: affordances and atmospheres that assemble childhood and motherhood on-the-move

The child-friendly city advocates for children's ‘right to the city’. Much of this advocacy focuses on the independent child, with little attention paid to the accompanied experiences of younger children, such as those travelling in prams. This paper draws on a material feminist perspective to help address this gap. We offer the concept of mother–child–pram assemblage to bring to the fore the corporeal dimensions of everyday pram journeys. By analysing sensory ethnographic materials collected with mothers and young children living in Wollongong, Australia, this paper highlights how the ‘affective affordances’ and ‘affective atmospheres’ of pram mobilities shape urban experience by reference to how motherhood and childhood are achieved on-the-move. We conclude with policy-relevant insights for the child-friendly city.     

Sunflowers,youthful protestors and political achievements: lessons from Taiwan

ABSTRACT

In 2014, an interesting youth movement collective started small p political and big P Political action and resistance in Taiwan. Their protest was against the way a major trade agreement proposed between China and Taiwan was being non-democratically pushed through the Taiwanese legislature. In this article, we provide an analysis of the activities of the Sunflower Student Movement (SSM) as a means to record a relatively little-known youthful and youth-centric successful uprising. It serves to place the SSM, and other East Asian-based protests, on the map of young people’s political geographies, and explores the paradoxical political and spatial practices pursued by young Taiwanese. This case study makes visible the interconnectedness of big P/small p politics of everyday youth geographies within an Asian context.     

The voting strategies of young people: a conceptual framework

This study offers a new framework for understanding the decision-making strategies of first-time voters. Using data from in-depth interviews with young people prior to the 2013 Australian federal election, the paper explores the extent to which our participants were knowledgeable about the upcoming election and the degree to which they invested cognitive effort into making their voting choice. The analysis reveals five distinct voting strategy typologies, which we use to construct a conceptual model that identifies and describes different voting approaches employed by young people. The findings show that young people are not a homogenous group of disinterested and disengaged voters. Instead, within a population of young citizens there are varying levels of interest and effort being invested into electoral participation.     

从“良渚全考古”到“良博全展示”——以良渚博物院2018年改陈策展为例

良渚考古工作历经八十余年,考古内涵不断丰富,考古价值不断提升,已进入到"良渚全考古"时代,是边发现、边研究、边保护、边利用、边传承的模式。2018年良渚博物院改陈,进入"良博全展示"阶段。现有的展览全面展示良渚考古成果,全面呈现良渚文化内涵,全面阐释良渚文明价值,全面解读良渚遗存信息。良渚的展示除了依靠文物本身或图文所呈现和传递的信息,还采用过程性展示、功能性展示、复原性展示、对比性展示、演变性展示、场景性展示等多种手段,多角度、全方位地解读和展示遗物,力图将良渚文物的故事讲清楚、讲明白。     

人流联系和经济联系视角下区域城市关联比较——基于手机信令数据和企业关联数据的研究

手机信令数据所代表的人流联系与国内外研究常用的企业关联数据在测度城市关联存在何种差异,尚缺乏明确的研究。本文以江西省北部地区为研究对象,分别以手机信令数据、企业关联数据测度城市关联,比较了两种城市关联与城市之间空间距离、人口规模的关系,比较了两种城市关联网络的层级、结构、腹地。主要研究发现：人流联系不仅集中在城市周边地区,而且集中于较高等级城市之间;经济联系则主要集中在较高等级城市之间。人流联系、经济联系受到城市人口规模影响均较小。人流联系显著地符合幂函数空间衰减规律。手机信令数据和企业关联数据是两种不同的城市关联数据,但可互为补充,较为全面地反映城市关联。
