场域织补:旅游传统村落更新理论新议

文章引入织补理论和场域理论，采用理论演绎与概念诠释方法，从场域织补视角出发对旅游传统村落更新理论进行思辨。研究发现，旅游重构了传统村落更新方向与逻辑，村落“碎片化”提供了织补理论应用的复杂性与矛盾性条件；旅游引发传统村落场域解构为旅游、生活、生产三大子场域，资本分化和竞争加大场域内外压力并引致场域失调；在保持村落复杂性前提下，场域织补可通过调适场域而作用于旅游传统村落更新过程。研究认为，场域织补的基本内容包括文化场域织补和关系场域织补，可运用资本调适作为场域织补的技术工具。     

Geochemical characterization of ochre from central coastal British Columbia,Canada

The use of ochre and its presence in archaeological contexts is well documented archaeologically, ethnographically and historically. Elemental analysis of ochre is becoming increasingly common as a method for identifying ancient quarrying and mining practices, and for identifying patterns of resource use, trade and exchange. As this type of work has become more common it has become apparent that two critical issues need to be considered: (1) the need for systematic identification of trends and patterns in ochre geochemistry using appropriate statistical analyses, and, (2) consideration of geographic and geologic scale in relation to ochre chemistry. Because ochre is a heterogeneous material relative to other raw material types, it is necessary to apply multivariate and discriminant statistics to differentiate geochemical groups within a sample set. However, caution must be taken when interpreting statistical results at face value. Local geologic and geomorphologic conditions play a significant role in ochre chemistry and need to be taken into account when interpreting analytical results. The purpose of this project was to determine if geochemically distinct groups of ochre could be distinguished through neutron activation analysis (NAA) of archaeological and geological ochres from the central coast of British Columbia, Canada. The results show that it is possible to satisfy the provenance postulate and to differentiate chemical groups through elemental characterization and using multivariate statistical methods.
