ABSTRACT. This paper aims to explore the (re)construction of identities in three regions adjacent to the Russian–Ukrainian border. The article analyses the areas' historical and political development and argues that placing such areas within a mega‐region term such as ‘eastern Ukraine’ fails to recognise important differences between them. Content analysis of regional history textbooks reveals that the ‘official’ state historical narrative found in school history textbooks is heavily negotiated, with regional elites in each area ‘picking and choosing’ which parts of the ‘official’ state narrative to accept and which parts to reject. In this way, the article demonstrates how the notions of ‘inclusion’ and ‘exclusion’ are highly debated topics in the Ukrainian classroom as the central and local state elites are both part of the dynamic process of (re)definition of national identities.  相似文献

A long‐term pump test was conducted in the KTB pilot borehole (KTB‐VB), located in the Oberpfalz area, Germany. It produced 22 300 m3 of formation fluid. Initially, fluid production rate was 29 l min?1 for 4 months, but was then raised to an average of 57 l min?1 for eight more months. The aim of this study was to examine the fluid parameters and hydraulic properties of fractured, crystalline crusts as part of the new KTB programme ‘Energy and Fluid Transport in Continental Fault Systems’. KTB‐VB has an open‐hole section from 3850 to 4000 m depth that is in hydraulic contact with a prominent continental fault system in the area, called SE2. Salinity and temperature of the fluid inside the borehole, and consequently hydrostatic pressure, changed significantly throughout the test. Influence of these quantities on variations in fluid density had to be taken into account for interpretation of the pump test. Modelling of the pressure response related to the pumping was achieved assuming the validity of linear Darcy flow and permeability to be independent of the flow rate. Following the principle ‘minimum in model dimension’, we first examined whether the pressure response can be explained by an equivalent model where rock properties around the borehole are axially symmetric. Calculations show that the observed pressure data in KTB‐VB can in fact be reproduced through such a configuration. For the period of high pumping rate (57 l min?1) and the following recovery phase, the resulting parameters are 2.4 × 10?13 m3 in hydraulic transmissivity and 3.7 × 10?9 m Pa?1 in storativity for radial distances up to 187 m, and 4.7 × 10?14 m3 and 6.0 × 10?9 m Pa?1, respectively, for radial distances between 187 and 1200 m. The former pair of values mainly reflect the hydraulic properties of the fault zone SE2. For a more realistic hydraulic study on a greater scale, program FEFLOW was used. Parameter values were obtained by matching the calculated induced pressure signal to fluid‐level variations observed in the KTB main hole (KTB‐HB) located at 200 m radial distance from KTB‐VB. KTB‐HB is uncased from 9031 to 9100 m and shows indications of leakage in the casing at depths 5200–5600 m. Analysis of the pressure record and hydraulic modelling suggest the existence of a weak hydraulic communication between the two boreholes, probably at depths around the leakage. Hydraulic modelling of a major slug‐test in KTB‐HB that was run during the pumping in KTB‐VB reveals the effective transmissivity of the connected formation to be 1 to 2 orders of magnitude lower than the one determined for the SE2 fault zone.  相似文献

Carbon and nitrogen stable isotope analyses were undertaken on human and faunal remains from two Neolithic sites in Southern Germany; the LBK settlement at Herxheim and the middle Neolithic cemetery at Trebur. Stable isotope data were used to reconstruct the diets of individuals buried at these sites and to look at dietary variation between groups classified by their sex, age, grave goods and cultural affiliation. Overall there was surprisingly little variation in the diet between the groups, as described by the stable isotope analysis, despite significant differences in the composition of grave goods. Also surprising, considering the archaeological evidence for extensive grain cultivation in this region during the Neolithic, was that the majority of individuals had δ15N values consistent with the consumption of significant amounts of animal protein.  相似文献

Why do citizens choose to attend or not to attend community public meetings about possible cancer clusters? To answer this question, we examine self‐report data collected during a series of mail surveys conducted in six communities experiencing current health investigations into suspect levels of cancer or cancer clusters. We analyze the data using quantitative content analysis while also providing qualitative summaries and categorizations of survey participants' reasons for attending or not attending a specific public meeting in their community. In addition, we use survey data related to respondents' past participation and sociodemographic characteristics. The results found that rational reasons (e.g., to get information) dominated citizens' justifications for attending the public meetings, whereas socioeconomic and mobilization factors (e.g., did not hear about meeting, too busy) were most commonly cited as reasons for not attending. Less common but still present were relational considerations, such as believing the people in charge were fair. Taken together, the findings suggest that the majority of citizens who attended the public meetings could be categorized as the curious, the fearful, and the available. In comparison, the majority of citizens who did not attend could be described as the uninformed, the indifferent, the occupied, and the disaffected.  相似文献

Peyote, a psychoactive cactus native to the Chihuahuan Desert, has been preserved from excavations at only two archaeological sites: Shumla Caves in the Lower Pecos region of southwest Texas and shelter CM-79 near Cuatro Ciénegas in Coahuila, Mexico. We determined three indistinguishable radiocarbon ages of 5160 ± 45, 5200 ± 35, and 5210 ± 35 14C years BP, yielding a mean age of 5195 ± 20 14C years BP for the three specimens from Shumla Caves. For one of the Cuatro Ciénegas specimens we obtained the first direct radiocarbon date of 835 ± 35 14C years BP. This study demonstrates the use of peyote by inhabitants of the Lower Pecos region of the Chihuahuan Desert about 6000 calendar years ago, and confirms its use by inhabitants of the Cuatro Ciénegas region of the Chihuahuan Desert in Late Prehistoric times. The Shumla Caves' specimens are composed of an aggregate of ground peyote mixed with other plant material, i.e., they appear to be manufactured peyote effigies, and are definitely not intact peyote buttons.  相似文献

We successfully combined ultrastructure and chloroplast DNA analysis for single specimens of Concentricystis isolated from Holocene sediment by a palynology method based on filtration, progressive sieving and percoll-gradient sedimentation to concentrate fossil cells. We compared our method with the traditional harsh chemical treatment commonly used to isolate fossil pollen and spores. With our method, the cytoplasm of Concentricystis was sufficiently preserved to distinguish several cell structures by light and electron microscopy. DNA analysis of Concentricystis involved PCR amplification using specific primers for a spacer region of the chloroplast genome. Significant homologies were found with the Angiosperm chloroplast genome by BLAST DNA search for PCR product sequences.  相似文献

A piston-type mud sampler is described. It is a development of the Livingstone corer and was designed to extract cores for DNA analysis of sediments. Prevention of contamination was paramount. As the entire system is self-contained and the sample is retained in the corer, it was found ideal for extracting very soft sediments which could not be captured by existing corers.  相似文献
