Topic Modeling and Text Analysis for Qualitative Policy Research

This paper contributes to a critical methodological discussion that has direct ramifications for policy studies: how computational methods can be concretely incorporated into existing processes of textual analysis and interpretation without compromising scientific integrity. We focus on the computational method of topic modeling and investigate how it interacts with two larger families of qualitative methods: content and classification methods characterized by interest in words as communication units and discourse and representation methods characterized by interest in the meaning of communicative acts. Based on analysis of recent academic publications that have used topic modeling for textual analysis, our findings show that different mixed‐method research designs are appropriate when combining topic modeling with the two groups of methods. Our main concluding argument is that topic modeling enables scholars to apply policy theories and concepts to much larger sets of data. That said, the use of computational methods requires genuine understanding of these techniques to obtain substantially meaningful results. We encourage policy scholars to reflect carefully on methodological issues, and offer a simple heuristic to help identify and address critical points when designing a study using topic modeling.     

《明实录》建文朝科举书写及其意涵

科举是建文历史的重要内容,也是其"文治"的具体表现。然而,《明实录》书写的建文朝科举,既缺乏三级科举考试的正面记载,又大体上掩盖了附传传主建文年间科举中式的信息。本不属于政治敏感性问题的科举史事,因其体现了建文帝泽被天下士子的恩典、妨碍了朱棣"文治"的弘扬,遭到了《明实录》的排斥。这表明实录对建文历史的讳饰,不只限于政治敏感性问题,而是一切有利于建文帝形象的史事。值得注意的是,史官在实录编修中采用春秋笔法披露了建文朝科举的蛛丝马迹,使得相关史事并没有在"国史"话语体系中完全被湮没。这反映出史官与君主在建文历史的认识、评价方面,存在一定的差异,此种现象并非晚明才出现,而是明初已露端倪。     

A new sociology of nationalism: The sociology of property and nation

In this essay, I will reflect upon what has been sociology's contribution to understanding the emergence and development of nationalism and how sociology can contribute to understanding nationalism's present and future through a property rights perspective. The essay will discuss, in particular, how historical sociological analysis of property rights and property rights regimes may be central to understanding nationalism past and future. After a general and brief discussion on the current, so‐called return of nationalism, the essay starts with discussion of some late enlightenment proto‐sociologists, suggesting that these writers actually analysed some crucial early dynamics of property and sovereignty which is central to understanding nationalism. The essay then moves on to suggests why a property rights focus might be a useful perspective to understanding nationalism in the 21st century.     

汉代漆器的剖析

通过制备并分析一系列模拟漆膜样品。建立了有助于鉴定汉代漆器成分的剖析方法。经裂解气相色谱、差热分析、色谱一红外联用等现代分析技术对出土的汉代漆器残片样品的综合分析,证实在西汉漆器制造中已使用桐油或其它的添加剂,并依据剖析的结果,对某些汉代漆器的原材料差异作了初步探讨。     

饱水木质文物的风冷干燥脱水研究

许多出土饱水木质文物因其降解严重、含水率较高,容易在脱水过程中出现不可逆的收缩变形以及开裂现象,从而遭到严重破坏。因此,饱水木质文物脱水方法的研究是文物保护工作中的重要课题。为探究风冷冷冻法对饱水木质文物脱水的效果,以一批无法复原的出土饱水木质文物为研究对象,在对其材种、含水率、基本密度及化学成分进行了测定和分析后,使用一台风冷电冰箱在-18℃条件下对样品进行了风冷干燥脱水处理,记录脱水时间和脱水效果,并分析了该方法的传质传热特点,证明了风冷干燥法用于饱水木质文物的脱水干燥能够取得良好效果,并且具有对文物干预小、适用性广、操作简便、成本低廉等优点,为饱水木质文物的脱水处理提供了一种新的思路。     

New Philadelphia: using augmented reality to interpret slavery and reconstruction era historical sites

Does a historical site lose its significance or become less worthy of interpretation if there are no surviving buildings? Can technology help present the stories of disadvantaged and disenfranchised groups whose heritage lacks well-preserved architecture or material culture? The emerging technology of augmented reality (AR) offers new ways of designing and shaping the public’s experience when visiting landmarks by enabling an unprecedented means to combine 3D historical visualization with historical landmarks. This especially applies to underrepresented groups whose heritages have not been well served by traditional modes of preservation and interpretation due to a variety of factors. These range from disadvantages relating to material culture to a greater emphasis on intangible heritage which have placed them outside the bounds of what archaeologist Laurajane Smith calls authorised heritage discourse. A project at the New Philadelphia National Historic Landmark, located in Pike County Illinois, seeks to address these issues through AR. The technology, while offering opportunities for historical interpretation, poses challenges in terms of designing AR systems that coordinate content presentation with specific locations as well as developing virtual historical content with varying levels of source materials.     

ANTHROPOCENE TIME

Beginning with the question of how a sense of geological time remains strangely withdrawn in contemporary discussions of the Anthropocene in the human sciences and yields place to the more human‐centered time of world history, this article proceeds to discuss the differences between human‐historical time and the time of geology as they relate to the concept of the Anthropocene. The article discusses the difficulty of developing a mode of thinking about the present that would attempt to hold together these two rather different senses of time and ends with a ground‐clearing exercise that might enable the development of such thought.     

Loyalist,patriot, or colonizer? The three faces of Zheng Chenggong in Meiji Japan and late Qing China

ABSTRACT

This article examines the transformation of Zheng Chenggong’s image in Meiji Japan and late Qing China. Prior to the mid-nineteenth century, Zheng Chenggong was often depicted as a Ming dynasty loyalist in Chinese narratives and as a Japanese hero adventuring in a foreign land in Japanese narratives. The two groups of narratives converged in the late nineteenth and early twentieth centuries, transforming Zheng Chenggong into a patriot, an anti-imperialist hero, and a conqueror and developer of Taiwan. Underlying the convergence of Chinese and Japanese narratives of Zheng Chenggong was surging nationalist sentiment in response to different forms of imperialism. This study aims to show how different nationalist agendas activated efforts to recreate Zheng Chenggong’s image in China and Japan at the turn of the nineteenth century.
