Across cities, one observes similarities in poverty and earnings of individuals within the same neighbourhood. Are these similarities due to causal influences neighbours exercise upon each other or to spatial sorting? We analyse this within the frame of a fixed effects model, estimated on a register-based panel covering all residents of two urban areas in Norway over the years from 1997 to 2011. We find a significant depressing effect of the share of low-earners in the neighbourhood on individual earnings in the capital region - Oslo. Our estimates of the impact of neighbourhood poverty are small in magnitude compared to what is found in other studies. In the other, less central area studied, we do not find any such effect. It is tempting to speculate that sorting and neighbourhood effects are less intense in urban regions with a smaller menu of neighbourhood choices.

存世印谱中比较常见的一类病害是印蜕中印油老化导致的渗化问题。研究表明,印油渗化不仅会在印蜕四周形成黄色或棕色的油渍,而且会导致纸张pH值降低,影响印谱的长久保存。通过对印泥中常用的蓖麻油、菜籽油、茶油、调和印油等六种油脂进行模拟老化实验,发现油脂老化后普遍存在变色、pH值下降和渗化问题。采用气相色谱-质谱联用技术分析老化前后的油脂样品,发现油脂在老化过程中,不饱和脂肪酸含量降低,饱和脂肪酸占比增加,并形成了壬二酸等脂肪族羧酸。油脂老化过程中的成分变化,导致了变色、酸化、渗化等一系列问题。在印谱实物样品中也发现了饱和脂肪酸。在印谱的保护工作中,应对油脂的老化进行有针对性的处理。 相似文献

ABSTRACT This paper investigates the extent to which house–price uncertainty affects the transition of renter households into homeownership. Using a 14‐year household panel from the Panel Study of Income Dynamics during the years 1984–1997 and measures of the time‐varying risk and return to owner‐occupied housing, we estimate a Cox proportional hazard model of the effect of house–price volatility on the transition into homeownership. Results indicate that house–price uncertainty has a negative and dramatic impact on transitions into homeownership. In addition, we find that the low‐wealth renters are particularly sensitive to house–price risk. 相似文献

ABSTRACT. This paper contributes to debates on decolonizing geography, by reflecting on the ethical and political considerations involved in research on indigenous music in Australia. The research collaboration involved two non-indigenous researchers—an academic geographer and a music educator—engaging with indigenous music and musicians in a number of ways. The paper reflects on these engagements, and draws attention to a series of key binaries and boundaries that were highlighted and unsettled: 'outsider/insider'; 'traditional/contemporary'; 'authenticity/inauthenticity'. It also discusses the politics of publishing and draws attention to the ways in which the objects of our work—in this case a book—influence decisions about representation, subject matter, and interpretations of speaking positions. Rather than seeking validation for attempts to 'speak for' or 'speak to' indigenous musical perspectives, contemporary Aboriginality was understood as a field of intersubjective relations where multiple voices, representations and interventions are made. I discuss some ways in which the authors sought to situate their own musical, and geographical, knowledges in this problematic, and inherently political, research context. 相似文献

ABSTRACTIn 1771, Daniel Paterson entered into a publishing agreement with the bookseller Thomas Carnan to print and publish a travel itinerary known as Paterson’s Roads. This book was to become the most enduringly popular practical road book of the period. However, Paterson and Carnan were soon embroiled in litigation. This article examines the legal cases that arose when the geographical information contained in Paterson’s Roads was re-used, and improved upon, in a subsequent publication. It explores the background to the cases, focusing on what they reveal about the inner workings of the book and map trade of the period, as well as considering some of the broader historical ramifications. The article also demonstrates that these cases are of ongoing legal significance because they played an important role in developing some of the doctrines and principles of copyright law that continue to be controversial today. 相似文献

ABSTRACT The philosopher Anne Conway (1631-1679) owned a large library, and her reading and book ownership shaped her intellectual life in distinctive ways. Until now, however, almost nothing has been known about the details of her reading or her book collection. Current scholarship assumes that her library, like that of her husband, the third Viscount Conway (c. 1623–1683), was lost or dispersed after her death. This article presents previously unrecognised evidence of Conway’s book ownership, and identifies, for the first time, the only books currently known to survive from her personal library. It traces their path to their current location in the Old Library of Jesus College, Cambridge, through the library of the soldier, book collector, and Cambridge Fellow Francis Sterling (c. 1652-1692). The article demonstrates that the newly identified books reveal previously unknown patterns of intellectual exchange amongst Conway’s family, and argues that they have significant implications for our understanding of her early intellectual development. 相似文献

Be Part of the Story: A popular geopolitics of war comics aesthetics and Royal Air Force recruitment
This paper provides an analysis of images associated with the British Royal Air Force's recent ‘Be Part of the Story’ war comic-styled military recruiting campaign. Set around literatures in popular geopolitics, the paper builds on the concept of comic book visualities to suggest that the ‘Be Part of the Story’ images reproduce longstanding war comics conventions, and coherently represent the complex, relational and spatially disparate battlespaces of the present. The paper, firstly, provides a detailed history of war comics as they have mediated war to publics, and argues that war comics should figure more strongly in future studies of popular geopolitics. Secondly, it argues that more than simply part of a pervasive ‘cultural condition’ of militarization, military recruitment is a vital medium through which states and militaries view, and choose to represent their role in the world. Lastly, it demonstrates that ‘Be Part of the Story’ reproduces the violent visions, metaphors and cultural designations integral to state-centric narratives of global politics, and specifically, spatial principles inherent to network-centric warfare. 相似文献

作为世界第二和第三的大能源消费国,中国和日本在分散竞争的条件下承受了过多的进口成本。本文在分析能源商品的价格决定因素基础上,探讨中日两国进行能源联合议价的成本与收益。认为这种努力可以在消除能源的亚洲溢价、减少能源竞争成本、促进亚洲能源期货市场发展、增强区域经济联系等方面获得显著收益。同时,联合议价的经济成本比较小,国家安全成本和政治成本则在两国之间存在不对称性,并且难以量化。 相似文献
