公共交通可达性分析方法进展

公共交通可达性拥有空间属性、时间属性、社会属性和经济属性,它是一种衡量区位价值的综合性指标,不仅可以反映城市空间特征,同时对城市中生活的人的社会经济属性和生活习惯,具有一定的解释力。为了不断适应新形势下的交通发展要求,减少环境负担,早日实现低碳绿色发展,创新公交都市规划与分析方法迫在眉睫。本文对基于个人的、基于效用的、基于基础设施的和基于位置的可达性研究进行了回顾,并归纳了七种公共交通可达性的分析方法,分别为：基于缓冲区的公共交通站点可达性、基于供需模型的公共交通面状可达性、基于网络分析法的公共交通网络可达性、基于成本栅格法的公共交通可达性、基于成本栅格与网络分析的集成法的公共交通可达性、基于高性能图形数据库的公共交通高精度可达性、基于开放地图 API 的公共交通高精度可达性。 以期为我国未来公共交通可达性的分析方法提供指引和借鉴。     

Alfred Russel Wallace as ancestor figure: Reflections on anthropological lineage after the Darwin bicentennial (Respond to this article at http://www.therai.org.uk/at/debate)

The article argues that anthropology might look to Alfred Russel Wallace as an ancestor figure for three reasons. First, it is under‐recognized that he was an accomplished and sympathetic ethnographic fieldworker. Second, evidence is emerging that his intuitions were surer than were Darwin's as to evolutionary mechanisms. Third, he was willing to appear as a “crank” on questions of ontology. These last two issues animate anthropology as we presently know it, and Wallace's stances on both may serve as a salutary inspirations.     

Ideological Migration and War Resistance in British Columbia’s West Kootenays: An Analysis of Counterculture Politics and Community Networks among Doukhobor,Quaker, and American Migrants during the Vietnam War Era

This paper addresses migration, war resistance, and counterculture activity in the West Kootenays region of British Columbia during the 1960s and 1970s. Through a combination of perspectives including S.N. Eisenstadt’s discussion of “multiple modernities,” it reveals an ongoing pattern of alternative, values-based migration we refer to as “ideological migration.” Most immediately associated with the influx of thousands of young Americans who came to the West Kootenays during the Vietnam War, this pattern, in fact, began much earlier, first with the arrival of the Doukhobors beginning in 1908, and subsequently in the 1950s with the development of a community of American Quakers at the north end of Kootenay Lake. From there, we show how common experiences of marginalization along with with shared values of pacifism, war resistance, community-building, and self-sufficiency facilitated the arrival of this new group, and with them the entrenchment in the region of a vibrant counterculture identity.     

The way we wear makes the difference: residue analysis applied to Mesolithic personal ornaments from Hohlenstein-Stadel (Germany)

Research conducted by Newell et al. (1990) has lead to propose that during the Mesolithic, the Upper Danube region was inhabited by a “Fish Teeth Band”, characterized by the use of carp fish teeth and exogenous fossil shells as ornaments. However, technological data on these personal ornaments drastically lacked and especially for the fish teeth associated to the Mesolithic burial of Hohlenstein-Stadel that remained completely undescribed until now. The aim of this paper is to establish how the carp teeth from Hohlenstein-Stadel were modified and worn before being deposited in the burial. High-resolution microscopic analysis identifies use-wear traces and a red compound adhering to the surface of the teeth. Structural and elemental analysis of the residue combining light and scanning electron microscopy, infrared spectroscopy, and Raman analysis identify a suspension technique that uses an adhesive composed of an organic binder mixed with charcoal and minerals including hematite, dolomite, and quartz. Ethnological inquiry reveals that this system of suspension, commonly used in traditional societies, is for the first time documented, at Hohlenstein-Stadel, in an archaeological context.     

Seasonality and season of birth of modern and late Neolithic sheep from south-eastern France using tooth enamel δO analysis

Stable oxygen isotopic analysis of tooth enamel was used to investigate seasonality and season of birth in sheep. Analyses were performed on the teeth of eight modern sheep bred at the Carmejane farm in south-eastern France and born in different periods of the year. This reference data set confirms that oxygen isotopic records in the second and third molars can be used to differentiate between sheep born in late winter and those born in early autumn. The results show that inter-individual variability in the timing of tooth formation is low for the second lower molar and more pronounced for the third lower molar in this population. The duration of the process of enamel mineralization has been estimated at approximately six months. The teeth of four sheep and two goats from the late Neolithic site of Collet-Redon in south-eastern France were analyzed using the same methodology. At this site, lambing occurred between the late winter and early spring. A slight difference appears in the seasonal sequence recorded in sheep and goat, although it cannot be determined, whether this is due to different timing of tooth development, or an actual shift in the birth period. From the distribution of slaughter ages and birth period, it is suggested that domestic caprines were killed throughout the year and that Collet-Redon was probably a permanent settlement.
