DETERMINING THE SEASON OF MISSISSIPPIAN HOUSE CONSTRUCTION FROM PLANT IMPRESSIONS IN DAUB

Abstract

It has been suggested that Mississippian farmsteads in some parts of the Southeast were abandoned in the late fall/early winter, with concomitant population concentration in large, palisaded villages. This assertion is contradicted by published data on plant impressions in daub which indicate farmstead house construction during the fall. Missing from this debate has been information on the season of house construction at mound centers. Plant impressions in daub from a structure at the Lyon’s Bluff site (22OK520) in Mississippi indicate that house construction took place during early to midspring. When coupled with other data, year-round construction at this mound and village complex is suggested. Although these results do not solve the question of the season of house construction at farmsteads, they do suggest that house construction at mound sites was not confined to any particular season of the year, as might be expected with seasonal influxes of farmstead inhabitants.     

AN ANALYSIS OF TWO-CENTER COMPETITION

This paper analyzes the competition between the two centers which belong to different hierarchical levels. A two-center competition model is constructed by applying the Lotka-Volterra equations. This model includes as parameters the scale economies of central places, the consumer's outflow from the region, as well the distance between centers. As it is assumed in this model that the carrying capacity of the region will be affected by the consumer's outflow rate from it, the outflow rate is estimated by a demand generation model and then incorporated into the two-center competition model.     

AN EXAMINATION OF POPULATION-GROWTH-MANAGING COMMUNITIES

This paper examines the fiscal, social, economic and environmental characteristics of 228 cities and counties. Using cluster analysis, 210 communities were classified into eleven types of communities. The empirical typings appear to support the proposition that communities control population growth to avoid adverse fiscal and environmental impacts and maintain the social and economic character of the community.     

试论灾害旅游的伦理均衡

灾害旅游作为汶川灾后重建的一种发展思路而受到关注,而这必然会涉及伦理问题。本文基于伦理学视角,用系统的方法分析了作为灾害旅游中矛盾双方的旅游者和旅游地在各方面表现出的冲突及伦理问题,即各自在道德和利益两方面的矛盾。通过伦理视角来审视灾害旅游的发展,具有一定创新性。本文认为,在灾害旅游的开发过程中,需要兼顾旅游者与旅游地,道德和利益之间的均衡关系;需要通过加强制度建设,用外在的力量来约束各利益主体的行为,并通过教育,以加强自律的方式引导各个利益主体的行为。

高新技术产业布局特征分析

影响高新技术产业布局的区位因子主要是知识、技术、资金和信息。地方政府对高新技术产业的扶持因素和对外开放条件对高新技术产业区位选择的影响越来越大。高新技术产业区位具有智力密集、良好的外部发展条件、对外开放度高和交通方便、生产和生活环境质量相对较高、位于大中城市等特征。高新技术产业布局存在着区域集聚与扩散两种过程。
