An Archaeological Study of a Streetcar Suburb: The East Main Streetcar Barns and Hayward-Hobbie Subdivisions,City of Rochester,New York

ABSTRACT

In order to appreciate the social dimensions of the industrial past, any research examining how working people both laboured and lived must recognise that sites of production and distribution may share a close relationship with the household, a relationship that will influence consumption and settlement patterns. Using artefactual and documentary evidence, this paper examines the initiation and growth of the Beechwood neighbourhood, a former streetcar suburb, located in the eastern section of the City of Rochester in western New York State. Streetcar suburbs in cities throughout the United States have received attention from geographers and urban historians for some time. This paper builds on previous studies by considering how transportation infrastructure — here, a maintenance facility and railyard for repairing inter-urban and intra-urban trolley cars — influenced the demographic and material patterns in one section of the neighbourhood in the first decades of the 20th century.     

Influence of Taoism on the invention of the purple pigment used on the Qin terracotta warriors

Until the 19th century, most pigments were based on naturally occurring colored minerals and dyes, with three significant exceptions: Egyptian Blue, Chinese Blue/Purple and Maya Blue. The former two are alkaline-earth copper silicates, and because of this similarity it has been proposed that the Chinese pigments were derived from Egyptian Blue. Herein, we analyzed clumps of pigment from the Qin warriors and discovered that in spite of the structural similarity to Egyptian Blue, the micro-structural morphology of Chinese Purple is very different. Therefore, we believe that the synthesis technology for the Chinese pigments was a by-product of high-refractive index glasses (artificial jades) produced by Taoist monks. Further, the disappearance of these pigments from Chinese art and monuments concurrently with the decline of Taoism not only substantiates the link between the two, but also gives a striking example of how cultural changes in the society affected the scientific developments in ancient China.     

驰骋西北的平阳商帮

平阳商帮作为晋商的一支,明清两代是其发展的重要阶段,清末民初逐渐由繁盛走向衰落。平阳商帮经贸西路,其经营地点基本为丝绸之路沿线城市如西安、兰州、银川、武威、酒泉、西宁等,其经营行业涉及盐业、冶铁业、布业、烟业及茶叶等。明朝"开中法"的实施为平阳商人经贸西路拉开了序幕,丝路贸易的繁荣吸引平阳商人前去经商,"互通有无"的商业模式给平阳商人提供了商机,便利的交通亦是平阳商人经贸西路的重要条件。     

Modern roads as UNESCO World Heritage sites: framework and proposals

There has been noticeable development in the protection of linear infrastructure by UNESCO, whether on its cultural, technological or historical merits. However, with the exception of other means of transport incorporated within the field of industrial archaeology or recognised by the CIIC under the category of cultural routes, little or no consideration has been given to roads built from the mid-eighteenth century to the early part of the twentieth century. In view of this situation, this paper has the following aims. Firstly, to define the concept of ‘modern road’ and provide a brief analysis of the historical development and current situation of the same. Secondly, to assess the main contributions made to date regarding the heritage dimension of modern roads. Thirdly, to reconstruct the process of defining linear cultural landscapes, historic transportation corridors, cultural routes and heritage canals, railways and roads, in accordance with the considerations raised by ICOMOS and UNESCO. Finally, to contribute to the debate on the definition, characterisation and assessment of modern roads as world heritage assets, both intrinsically and in relation to established heritage categories.     

How does transportation shape intrametropolitan growth? An answer from the Regional Express Rail

This paper analyzes the influence of transportation infrastructure, and in particular of the Regional Express Rail (RER), on employment and population growth in the Paris metropolitan area between 1968 and 2010. In order to make proper causal inference, we rely on historical instruments and control for all other transportation modes that could be complement or substitute to the RER. Our results show that proximity to an RER station increases employment and population density and, in particular, employment and population growth. The latter effects are higher in municipalities located near RER stations and close to employment (sub)centers. They are also found to be particularly strong for jobs in the service sector, for factory workers, and for highly educated population. We find no impact of the RER expansion on employment growth during the first part of the period, while the effect on population growth appears earlier but declines over time.     

The Transportation Sector of India's Economy: Dry Ports as Catalysts for Regional Development

Two East Asian specialists review the development of dry ports in India as part of a broader national program to eliminate transportation bottlenecks, improve transport efficiency, and spur the economic development of interior regions by lowering road and rail freight tariffs, and thus decreasing the costs of imports (and making exports more competitive). A key focus is on comparing the relative efficiency of public- versus private-sector operation of dry ports, and on examining the effects on dry port efficiency of current Indian Government policy. The authors test two hypotheses relating to the efficiency of port operations using information derived from their field study/interviews at 28 dry ports in Northwest India (reflecting three different types of ownership/operation combinations) as well as quantitative data measuring port efficiency.     

毛泽东对中国社会主义现代化战略的思考与选择

以毛泽东为代表的中国共产党人总结了历史经验和教训,开辟了一条先谋求民族独立、创造现代化的前提条件,再集中力量进行现代化建设的正确的救国之路;改革开放以前中国虽没有全面实现现代化,但中国共产党第一代领导集体也已经制定了一个适合国情的发展战略,并在此基础上进行了艰辛的探索,奠定了中国经济、社会继续发展的坚实基础。     

清代新疆冰岭道建置考

冰岭道作为乾隆平回之后为屯田伊犁而设的首条官方台路,其重要性自不待言。然而,长期以来,学界对这一问题的研究却较为缺乏。近年来,虽有学者对冰岭道做了专门探讨,但对于此路最为重要且变化最为剧烈的建置初期的情形,却由于汉文史料的匮乏而论述简略,考证失实。有鉴于此,本文在吸收前人经验的基础上,充分利用满汉文史料,对冰岭道的建置情形进行了考察。首先,证实了冰岭道建置初期并非仅有两阶段,而是有着层次分明的三个阶段。其次,对三阶段中所设台站的兴废增减进行了梳理,并阐明其调整过程不仅反映了台站职能的变化,更体现了清廷对新疆统治思想的变迁。最后,考证出伊犁驻防建设初期,伊犁地区与外界沟通的官方台路仅有冰岭道一条。     

近代皖北交通中心变迁再探--以津浦铁路淮河大桥选址变更为中心

临淮关凭借传统交通与商业中心的地位,成为津浦铁路淮河大桥桥址的首选之地,但由于该处地势低洼,不易建桥,桥址最终选定在蚌埠。蚌埠得津浦铁路和淮河水运之利,迅速崛起,成为皖北地区新的交通与商业中心,而临淮关则渐趋衰落,最终成为淮河岸边一个普通小城镇。究其原因,主要是由于桥址变更,引起交通区位优势的转换,蚌埠的交通优势转化为产业优势;铁路与淮河水运在蚌埠的有机结合以及政治因素的助推。     

城市化进程中交通公平的研究进展

在系统分析城市化进程中交通公平内涵的基础上,从弱势群体与社会排斥、交通公平评估与改善策略等方面,梳理交通公平的相关研究成果。结果表明,当前城市交通公平性研究还需从以下几个方面进行完善:交通公平内涵应更加注重改善快速城市化地区居民群体的出行环境;系统分析快速城市化进程中交通公平的演化模式,改善交通公平的基本测度方法;构建交通公平评估的空间分析方法,从经济成本可达性角度剖析交通公平性;关注快速城市化地区交通公平的改善策略,提出可操作性的交通公平优化方法。
