Drawing on data from the Korea Labour and Income Panel Study 1998?2008, this article attempts to assess the impact of female labour force participation on childbirth decisions in South Korea. To control for the dynamic processes through which soon-to-be mothers choose to get out of the labour force to give birth, empirical datasets using three different birth-month lag scenarios are examined: no lag; five-month lag; and eight-month lag. In addition parity-specific effects for the first and second childbirth are evaluated in consideration of previous findings showing different effects by birth order. Results suggest that, regarding the first birth, female labour force participation does not seem to have significantly diminished transition probability to first birth. Female labour force participation, however, appears to affect the second childbirth decision in a negative direction, although the impacts are not as great as have been widely publicised.  相似文献

Museums of History and Art provide accounts of the past and the transition of nations into their current situation. They follow a certain line of interpretation of past events which reflect the dominant belief system in a nation. These narratives told in this process leave room for interpretation. Which particular string of the available narratives is followed while neglecting the others, and is influenced by the current self‐understanding of a nation and its political considerations. Latvia and Lithuania, two Baltic Nations, were planning to set up museums of contemporary art in 2009 and in 2011, respectively. Due to the financial crisis at this time, however, both projects have been put on hold. Based on interviews with key personnel and experts, the paper shows how the museums in both countries interpret their Soviet past and align it with the new European master narratives.  相似文献

Abstract

Cahokia (a.d. 800–1400), located near the confluence of the Mississippi and Missouri rivers, was the largest settlement in ancient North America. Monks Mound occupies the center of Cahokia and provides both a modern and ancient focal point for the site. Past investigations of Monks Mound explored issues of mound chronology and use. Recent soil coring around the perimeter clarifies the geological context and degree of preparation necessary before the mound was built. The results suggest that the mound is not optimally positioned for stability and its location may ultimately accelerate deterioration. Moreover, evaluation of the mound features and fill indicates that maximization of the geotechnical potential of sediments was not a primary concern for the Cahokians. Although poorly engineered relative to modern standards, the suitability of the mound as a platform may have been secondary to other design choices made while building the largest single mound in ancient North America.  相似文献

Increasing interest in the Victorians' relationships with the material world has led many critics to turn to periodical publications and, in particular, to process articles and other forms of industrial writing as sources for new insight. This article contributes to this growing body of scholarship by examining narratives of doll production. Because dolls are objects that Victorians celebrated for their imaginative potential and that were often not intended to be treated as ordinary commodities, such narratives can shed light on the intricate relationships between materiality and the imagination. In revealing the process of production, these narratives deconstruct dolls, reducing them to a collection of material parts. By some accounts, these parts are brought to life through a specialized process of manufacture that dehumanizes the workers who make them and robs them of their imaginative agency. While this deconstructive exploration can be seen as an extension of the ‘melancholy and gloom’ that Baudelaire describes as the result of children's destructive compulsion to see the insides of their toys, it could also generate new imaginative possibilities. By inviting readers to behold commodities in a state of transformation, I argue, narratives of doll production demand a more imaginative attitude towards commodities as objects shaped by their material histories.  相似文献

内蒙古阿尔山森林资源枯竭型城市转型战略决策量化分析   总被引:1,自引:0,他引:1  
本文通过对阿尔山市实际情况分析基础上,采用层次分析法(Analytical Hierarchy Process),通过建模、计算,对阿尔山市资源枯竭转型战略作了定量化分析,得出以下结论:在相当长的时期内,阿尔山追求生态效益应是第一位的,因此加强森林资源环境的保护与生态治理是首要战略目标,且加强森林养护与生态功能建设是第一重要的发展战略;当前亟待解决的首要发展问题是森林资源枯竭及生态环境恶化、林业系统体制矛盾及资金欠账严重,应采取的重要措施是依托国家政策尽快建立生态补偿机制及衰退产业援助机制,加快阿尔山林业企业的资产剥离重组,理顺政府与林业局关系,进而培育以"绿色"为主题的接续产业体系。  相似文献

On reductionism and emergence in geomorphology   总被引:1,自引:0,他引:1  
Much geomorphological enquiry has been devoted to the understanding of landscapes via the construction of models based on the relationships between process and form. This paper examines the philosophical, theoretical and practical problems involved in bridging the gap between studies of geomorphological processes and explanations of landscape development. It argues that process geomorphology is essentially reductionist and discusses the practical and logical limitations of such an approach to science. It suggests that landscapes are emergent phenomena and, by drawing from the philosophical and practical lessons derived from the physics of non-linear systems, demonstrates that they are not amenable to reductionist explanations.  相似文献

中国古代地缘政治空间结构过程及模式研究   总被引:1,自引:0,他引:1  
姚晓瑞 《人文地理》2008,23(1):69-74
中国古代地缘政治的发展过程具有一种长周期内的重复态势。地理环境是空间结构存在的大尺度控制和自然基础。空间结构的动态过程包括秦以前结构的发生、发展和演变,秦以后结构的融合、扩散和模式化,反映中国古代地理政治化和政治地理化的两个阶段。结构模式的静态分析,初步揭示了结构的一些重要功能特性,主要有强大的整体功能,独特的边缘效应和通过圈层同构,结构复制所展现出来的稳定性的复杂表现。对中国古代地缘政治空间结构的分析,是大尺度的整体轮廓研究,随着空间结构研究尺度的细化,可进一步对中国古代政治过程的诸多特性做出结构主义的揭示,从而推动中国古代政治历史研究的深化。  相似文献

An archaeological case of clay‐shoveler's fracture was observed in an adult male exhumed from a Roman necropolis dated to the 1st–3rd century AD and located in the city of Barcelona, Spain. Clay‐shoveler's fracture is a breakage of a lower cervical or upper thoracic spinous process as a result of mechanical stress. Different mechanisms have been related to this injury, generally in labour‐related contexts. This paper reviews the literature concerning this uncommon finding, focusing especially on its mechanism and on activity‐related lesions. Copyright © 2006 John Wiley & Sons, Ltd.  相似文献
