The in situ preservation of archaeological remains: using lysimeters to assess the impacts of saturation and seasonality

Recent research has studied the effects of seasonal variability on waterlogged burial environments. In a new approach to the study of archaeological contexts, the use of controlled laboratory conditions via lysimeters has enabled new insights into the nature of short term fluctuations in saturation, and the impact that these can have on burial contexts. In addition, the protocols used have facilitated interesting insights into burial environments and the way in which fluctuations in saturation and seasonality can impact on the contained organic components within them.     

Southwest Scottish Crannogs: using in situ studies to assess preservation in wetland archaeological contexts

This paper presents the results of in situ monitoring of waterlogged burial contexts in southwest Scotland. The sites investigated are Iron Age crannogs (lake dwellings) which have a proven waterlogged archaeological component, and which are being assessed as part of a national program of study by the Scottish Wetland Archaeology Programme (SWAP) team. A monthly monitoring program commenced in July of 2004. To date, monitoring of water levels, pH, and redox potential, has been undertaken for a period of 17 months in order to encompass any seasonal variability at the sites studied. The results have proven robust in that an ‘ideal’ site for in situ preservation has been identified from the five sites investigated, and the monitoring has highlighted external variables and seasonal impacts that have the potential to influence the long-term in situ preservation at the remaining sites studied. In general, these results have expanded upon our knowledge of the potential for the preservation of existing archaeological remains within such contexts. This study represents the first stage of monitoring aimed at developing a holistic understanding of in situ conditions at the crannog sites studied in southwest Scotland.     

农村居民点用地整治潜力测算研究——以广东省五华县为例

以广东省五华县为例,以行政村为单元,在政策指标测算法的基础上,从自然环境状况、经济保障能力和社会因素等3方面构建理论潜力修正模型,将理论潜力修正为可实现潜力,并根据土地适宜性评价估算增加耕地潜力,以期为科学编制农村土地整治规划提供依据。研究表明,五华县农村居民点用地布局分散、规模小、空间差异显著,呈现出沿河谷、沿交通线路分布的典型特征。到2020年,农村居民点整治理论潜力为5683.91 hm²,北部村庄的整治潜力较大;可实现潜力修正系数为0.54,与理论潜力相差较大,各行政村之间差异明显;新增耕地潜力系数介于0.32-0.94,预计新增耕地1943.41 hm²,琴江、五华河沿线村庄的新增耕地潜力较大。建议实施差别化的农村居民点整治对策,推进五华县农村土地整治。     

Identifying the geochemical taphonomy of the osteological material from Katsambas rockshelter

We report analytical work undertaken in order to identify the geochemical taphonomy of the osteological collection (human and animal bones) recovered from a 1950s excavation at Katsambas, a small cavity in the marly limestone on the west bank of Kairatos River, Crete. The site had funerary use and yielded material of Neolithic and Minoan age with poor stratigraphical association. Disintegration of provenance labels from bags has introduced further uncertainty about the contexts of recovery. Samples of human and animal bones that macroscopically appear to belong to three taphonomic categories were studied by means of FT-IR spectroscopy, TEM microscopy and REE analysis to explore the taphonomical processes the bones have undergone. Although not novel in palaeontological research the use of REE opens a new path to investigating poorly provenanced osteological collections from old excavations. Such geochemical work offers a proxy to their relative dating through the evaluation of the time span bones have remained in the sediments and their respective taphonomic histories.     

基于空间特征的秦巴山区农村居民点整理分区与潜力测算

整理分区划定和整理潜力测算是农村居民点整理的核心内容。本文综合地形位、缓冲区、可达性、景观指数和Voronoi 图,引入空间分异特征指数,定量分析农村居民点用地特征,实现整理区合理划分;改进潜力测算模型,结合经济社会、土地利用、农户意愿因素,构建整理潜力综合评价指标体系,以秦巴山区竹溪县为例进行实证研究。结果表明：竹溪县农村居民点空间分异特征指数值位于0.0433-0.8038 之间;全县农村居民点可分为优先整理区、重点整理区、优化调控区和城镇发展区,现实潜力904.63 hm²,仅为传统潜力的65.42%;根据各乡镇潜力系数,划分为3 级潜力区。空间分异的潜力测算、整理区和潜力区划分,为确定因地制宜的整理模式和符合实际的整理时序提供依据。     

挖掘初中作文教学的学生潜力

学生作文语意表达不清,枯燥无味,主要是头脑中积累的词汇句子太少。只有让学生多读,才能开拓学生的思路,提高学生的写作能力。知识积累是过程,熟练运用是目的。在习作中,要教育学生恰当运用多种修辞手法表达语意,增强文章的感染力和语言的说服力,使抽象的内容具体形象生动。     

中国省域旅游业发展潜力的比较研究

对区域旅游产业发展潜力的测评,可以反映区域旅游产业发展的后续能力和未来前景。通过构建区域旅游产业发展潜力评价指标体系,运用因子分析法,借助SPSS统计分析软件,从旅游业产业发展角度出发,对我国31个省、市、自治区旅游业发展潜力的差异进行了量化研究。研究表明,我国东部大部分省域具有较强的旅游产业发展潜力,中部大部分省份旅游产业发展潜力居中,而西部大多省份的旅游产业发展潜力较弱,这与我国经济发展的差异基本上相似。同时,研究也发现,旅游发展潜力的强弱分布基本上与旅游竞争力的强弱分布是一致的。     

Unexpected Wind Power ‘Potentials’: The Art of Planning with Inherited Socio-Geographical Configurations (France)

Abstract

The deployment of wind power induces deep changes in landscapes and territories. The politicization of wind power generates new ad hoc collectives. In the French case, because of the institutional framing resulting from landscape and wind power policies (centralization, feed-in tariffs, private developers), collectives of emerging wind power landscapes are regularly set apart from wind power planning processes. This paper explores the extent to which these recompositions and new collectives could be part of emerging wind power potentials. The empirical evidence stemming from our case studies shows that wind power technology, like any other technology, is not endowed with a potential per se. Wind power potentials differ – ‘capitalistic’, ‘controversial’, ‘negotiated’, ‘conditional’ – depending on planning processes and inherited configurations. The notions of striated space and smooth space enable us to adopt a relational perspective on these emerging collectives and to account for the role of inherited socio-geographical configurations and planning processes.     

Holocene paleoshorelines,water levels and submerged prehistoric site potential of Rice Lake (Ontario,Canada)

Rice Lake, located in the eastern Great Lakes of North America, has a high density of prehistoric (11–0.5 ka BP) terrestrial archaeological sites. It has been speculated that a large number of sites are submerged on the lakebed, as lake levels have risen >9 m since the arrival of Early Paleoindian peoples (∼11 ka BP). In order to better understand the submerged landscape and its archaeological potential, a detailed bathymetric survey and sediment-coring program was conducted across a 30-km² area of northeastern Rice Lake. Changes in Holocene water levels and shoreline positions were reconstructed by integrating core data with a digital elevation and bathymetric model (DEBM) that accounted for differential isostatic uplift and basin sedimentation. The DEBM was used to generate a series of maps showing changes in the lake paleobathmetry and paleogeography and areas of prehistoric archaeological potential.
