Factors of party system fragmentation: A cross-national study

This article uses a representative sample of elections held in 82 countries of the world (1993–2012) for a statistical analysis of factors that explain the number of parties in national legislative elections. The analysis confirms that the proliferation of candidates and/or parties at the district level contributes to the number of national parties, but the other crucial determinant is party system nationalisation. Several factors that are believed to have an impact on party system fragmentation, such as economic wealth, federalism, linguistic fractionalisation and population size, exert their influence on the number of national parties indirectly, by affecting either the number of district parties or party system nationalisation. At the same time, the significance of many other factors, especially those pertaining to electoral systems and the general political–institutional context, can be properly estimated only if the strongest determinants of system-level fragmentation are controlled for.

本文使用了世界82个国家选举（1993—2012）的代表性样本,对国家立法选举中决定政党数量的因素进行了统计分析。作者认为,地区层次的候选人以及/或政党层出不穷,对全国性政党的数量有所影响,而政党体系的全国化也是一个关键因素。有几个因素估计对政党体系的碎片化有影响,像经济财富、联邦主义、语言及人口规模等等便通过影响地区政党的数量或政党体系的全国化,而对全国性政党的数量产生了间接的影响。与此同时,其他许多因素,尤其是涉及选举制度以及一般政治—体制环境的因素,也可以进行恰当地评估,但要以决定了体制层面碎片化的最强因素作为对照。     

Liberal party performance and polarisation

Nagel and Wlezien's ‘vacant centre’ theory suggests that parties close to the centre tend to do better when a political system is highly polarised, creating an empty space in the political market. Cross-nationally, this does not seem to be true when overall system polarisation is used as the independent variable: indeed, there seems to be a slight negative relationship. The farther apart conservative and social democratic parties are, however, the better that liberal parties tend to do. This parallels Nagel and Wlezien's findings for Great Britain specifically.

纳格尔和乌勒子安的“空虚中心”理论指出,在政治体系高度两极化、形成政治市场某种空虚的情况下,接近中心的政党可以做得更好。跨国地看,如果把整个系统的两极化看做自变量的话,这种说法不确,二者之间倒是有些负相关。不过,保守党和社会民主党背道而驰得越远,自由党就干得越好。这倒接近纳格尔和乌勒子安对英国情况的总结。     

Application of Particle Motion Technique to Structural Modal Identification of Heritage Buildings

Determining the behavior of a structure estimated by means of finite elements analysis requires not only an in-depth knowledge of its geometry and dynamic properties but also an experimental validation to corroborate the adequacy of the characteristics of the structure. Most of the current structural identification techniques are based on linear methods that call for many measurement points and/or a relative simple structure. Complex structures are somewhat still an unexplored field due to the difficulties with the finite element method and the experimental corroboration of its results. This study presents the use of particle motion computation applied to each structural vibration mode to improve the identification of its dynamic properties, and its application to the Gothic Cathedral of Palma de Majorca (Spain).     

曹魏薄葬考

曹魏时期的薄葬是相对秦汉厚葬而言,薄葬与厚葬在考古遗存上各有具体的体现,曹魏通过对汉代地面标记性设施和祭祀性设施、地下居室性设施和随葬明器的简省,开创了以薄葬为特征的新的丧葬模式,并影响着魏晋南北朝时期的丧葬。     

Developing Complex Societies in Southeast Asia: Using Archaeological and Historical Evidence

A number of archaeologists are making significant advances in the historical archaeology of Southeast Asia. The papers presented in this issue, and the one that preceded it, provide new insights and exciting directions for future research.     

Recent British research on prehistoric territorial boundaries

The British Isles are very rich, compared to the rest of Europe, in prehistoric boundary earthworks. There are difficulties in deducing prehistoric territories from them, mainly because of the incompleteness of other evidence of settlement patterns. Fortunately, in the past two decades there have been major advances in territorial studies, in particular, of the pattern defined by the reaves (long walls) on Dartmoor in Southwest England and in the Anglo-Saxon pattern in Southern England defined by boundaries in legal documents (charters). These studies enable some general principles of early land divisions to be deduced, particularly the relations of boundaries to the natural features of the terrain. These principles can be applied to the study of other early boundary earthworks, and, in some cases, reasonable deductions on the nature of the prehistoric estates can be made. The paper concludes with a discussion of major problems, namely, the dating of earthworks, the continuity of boundaries between prehistoric and historic eras, the functions of boundary markers, their chronological development, and their social implications.     

International rivers as border infrastructures: En/forcing borders in South Asia

Rivers have long been convenient yet troublesome borders. Inherently itinerant, rivers routinely defy cartographic depictions of borders as static, territorially bounded formations. Such dynamism poses material and conceptual challenges to state regulatory activities, resulting in increasingly heterodox attempts to fix waterbodies through various securitizing mechanisms. I examine the dialectical relationship between rivers and borders through the concept of the river-border complex. I ask how the Ganges River shapes the form and function of the Indo-Bangladeshi border and how, in turn, bordering practices in India regulate flows along the river, which comprises 129 km of India's border with Bangladesh. Drawing on archival records, in-person interviews, and river data, I find that the border and efforts to secure it mediate many flows along the river. The study corroborates previous work within critical border studies that securitizing cross-border flows has the perverse effect of generating greater insecurity in adjoining countries. Crucially, historical analysis of sediment, information, and human flows reveals how international rivers also determine patterns and processes of circulation and thereby warrant reconceptualization as border infrastructures, rather than as merely being subject to them.     

多情境下城市时空间行为的社会分异——以北京不同住房来源居民为例

近年来,居民时空间行为的社会分异已成为学者们广泛关注的话题。然而,已有关于居民时空间行为的社会分异研究中,缺少对于居民活动情境的社会分异的研究。因此,本研究基于时间地理学中对人类活动的情境嵌入性与情境的不同维度的相关理论,以北京清河街道为例,分析不同住房来源居民在日常情境、地理情境和社会情境下的时空间行为的社会分异,尝试从多个情境维度拓展对时空间行为社会分异的理解。研究发现,市场性住房居民“朝九晚五”的活动特征明显,活动同伴选择外向性突出;单位性住房居民职住相对接近,在社区空间内分配时间最长且活动目的多样;安置性住房居民活动较为分散,地理情境与社会情境都呈现出“家庭内向性”特征;保障性住房居民非工作活动的“滞后性”明显,对社区空间的时间分配总体较低。除住房来源因素与个人社会经济因素外,建成环境因素对于居民对社区空间的使用有显著影响。
