Średniowieczne wierzenia – nieczysta siła w kulturze Słowian

Książka jest zbiorem tekstów prezentujących szeroki wachlarz zagadnień dotyczących historii średniowiecznej Polski i Europy. W czterech działach – na wybranych, konkretnych przykładach – podjęto tematykę dotyczącą monarchów i ich rodzin, społeczeństwa i jego poczynań, sztuki, architektury i artefaktów życia codziennego, jak również światopoglądu ludzi wieków średnich. Tak różnorodne problemy badawcze zaciekawią wszystkich, którzy interesują się historią średniowiecza, w tym heraldyką, genealogią, archeologią czy historią sztuki

Ajdukiewicz o stosowalności czystej logiki do zagadnień filozoficznych

Ajdukiewicz about the applicability of pure logic to philosophical issues the paper is an analysis of the arguments contained by Kazimierz Ajdukiewicz in his article On the applicability of pure logic to philosophical issues (1934). the author argues that philosophers in support of their claims can not use pure logic statements as evidence. Because theses formulate their common language, they can only appeal to the logic of everyday language, an alternative to the modern systems of symbolic logic

Cross Recurrence Plot Based Synchronization of Time Series

The method of recurrence plots is extended to the cross recurrence plots (CRP), which among others enables the study of synchronization or time differences in two time series. This is emphasized in a distorted main diagonal in the cross recurrence plot, the line of synchronization (LOS). A non-parametrical fit of this LOS can be used to rescale the time axis of the two data series (whereby one of it is e.g. compressed or stretched) so that they are synchronized. An application of this method to geophysical sediment core data illustrates its suitability for real data. The rock magnetic data of two different sediment cores from the Makarov Basin can be adjusted to each other by using this method, so that they are comparable.Comment: Nonlinear Processes in Geophysics, 9, 2002, in pres

Palaeolimnology of Lake Sapanca and identification of historic earthquake signals, Northern Anatolian Fault Zone (Turkey)

Lake Sapanca is located on a strand of the Northern Anatolian Fault Zone (NAFZ, Turkey), where a series of strong earthquakes (Ms >6.0) have occurred over the past hundred years. Identifying prehistoric earthquakes in and around Lake Sapanca is key to a better understanding of plate movements along the NAFZ. This study contributes to the development of palaeolimnological tools to identify past earthquakes in Lake Sapanca. To this end several promising proxies were investigated, specifically lithology, magnetic susceptibility, grain size (thin-section and laser analysis), geochemistry, pollen concentration, diatom assemblages, 137Cs and 210Pb. Sedimentological indicators provided evidence for reworked, turbidite-like or homogeneous facies (event layers) in several short cores (<45 cm). Other indicators of sediment input and the historical chronicles available for the area suggest that three of these event layers likely originated from the AD 1957, 1967 and 1999 earthquakes. Recent changes in sediment deposition and nutrient levels have also been identified, but are probably not related to earthquakes. This study demonstrates that a combination of indicators can be used to recognize earthquake-related event layers in cores that encompass a longer period of time

Sedimentation rates in the Makarov Basin, central Arctic Ocean: A paleomagnetic and rock magnetic approach

Three long sediment cores from the Makarov Basin have been subjected to detailed paleomagnetic and rock magnetic analyses. Investigated sediments are dominated by normal polarity including short reversal excursions, indicating that most of the sediments are of Brunhes age. In general, the recovered sediments show only low to moderate variability in concentration and grain size of the remanence-carrying minerals. Estimations of relative paleointensity variations yielded a well-documented succession of pronounced lows and highs that could be correlated to published reference curves. However, together with five accelerator mass spectrometry C-14 ages and an incomplete Be-10 record, still two different interpretations of the paleomagnetic data are possible, with long-term sedimentation rates of either 1.3 or 4 cm kyr(-1) However, both models implicate highly variable sedimentation rates of up to 10 cm kyr(-1), and abrupt changes in rock magnetic parameters might even indicate several hiatuses

Osadnictwo mezolityczne w południowej części Pojezierza Łagowskiego

Despite a growing recognition of late Palaeolithic and Mesolithic settlement in recent years, the area of Pojezierze Łagowskie still represents one of less known regions of western Poland, both in terms of Old and Middle Stone Age settlement and reconstruction of of contemporary environmental conditions. The article provides results of technological, typological, functional analyses, as well as that of raw materials used in stone industry of Mesolithic communities occupying sites 13 and 16 in Wilenko. Majority of functional tools is characterised by use-wear traces, which should be interpreted as results of variability of meat, bone, antler, and leather processing activities or game hunting. In the article an attempt has been made to reconstruct environmental conditions, on the basis of the results of pollen analysis

Gender differences in colour naming

Gender differences in colour naming were explored using a web-based experiment in English. Each participant named twenty colours selected from 600 Munsell samples, presented one at a time against a neutral background. Colour names and typing onset response times were registered. For the eleven basic colour terms, elicitation frequency was comparable for both genders. Females demonstrated more elaborated colour vocabulary, with more descriptors in general and more non-basic monolexemic terms; they also named colours faster than males. The two genders differ in the repertoire of frequent colour terms: a Bayesian synthetic observer revealed that women segment colour space linguistically more densely in the “warm” area whereas men do so in the “cool” area. Current “nurture” and “nature” explanations of why females excel in colour naming behaviour are considered
