Spatial organization of the Gravettian mammoth hunters' site at Kraków Spadzista (southern Poland)

One of the largest and best known sites of the Central European Gravettian is the Kraków Spadzista site. This article summarizes archaeological, palaeontological, and zooarchaeological data from the site, obtained in the course of more than 40 years of excavations and studies. The site is known mainly from the discovery of the large mammoth bone accumulation in trench B. During field work conducted in a few trenches located close to this assemblage, numerous human artifacts and faunal remains were found. On the basis of analyses of lithic materials, faunal remains, and radiometric data it is concluded that the Krakow Spadzista site was frequently re-occupied during a few weeks or months, by groups of Gravettian hunters in the period 24–22,000 rcyBP This short-term camp site was related to mammoth hunting. The analysis allowed identification of three possible activity zones, characterized by the presence of different groups of flint tools, fireplaces, and different faunal assemblages: a camp area, a lithic workshop, and an animal-processing area, besides the well known accumulation of mammoth bones.

Age and sedimentological features of fluvial series in the Toruń Basin and the Drwęca Valley (Poland)

The deposits of the Toruń Basin are dominated by a few-metre thick sand series which fill up buried valley-like depressions. In many cases they underlie the Weichselian till which builds up the ice marginal streamway (pradolina) terraces or they are exposed at the basin slopes. As the results of the geological and sedimentological studies, as well as of the dating of the deposits at the sites in the Toruń Basin indicate, the deposits include two fluvial series accumulated before the advancement of the Leszno Phase ice sheet, i.e. in Middle Weichselian and at the beginning of Late Weichselian. The oldest fluvial series connected with the Saalian Glaciation was found at the mouth section of the Drwęca Valley. The fluvial system of the Toruń Basin during Middle Weichselian and at the beginning of Late Weichselian developed in two phases of the sand-bed braided river. During the first one the river channel were dominated by large mid-riverbed sandbars, while during the second phase the water flow was smaller and, as a result, low transverse sandbars and two-dimensional dunes developed. Other active river channel also showed low-energy flows, more intensive meandering than in the case of the braided rivers, as well as sandy side-bars. Analysis of the rounding and frosting of the quartz grains indicate that the studied series of the Weichselian sandy deposits represent alluvia of a river which were fed from two diverse sources. The first one might have represented the alluvia of a warm river which transformed its load, while the other one might have mainly carried the underlying Quaternary deposits.     

First ancient bovine DNA evidence from India: difficult but not impossible

Ancient DNA isolation from the tropical countries has been shown to be very difficult in the past. Here for the first time we have been successful in isolating ancient DNA from Indian cattle samples. We were able to obtain DNA and sequence the partial mitochondrial D-loop in 3 of the 15 bovine fossil samples ranging in age from 2000 BC to 1000 AD, and were able to further identify the most recent sample as being of Bos indicus origin. Our results on ancient DNA extraction from India will encourage other researchers in this field to carry out further studies of ancient DNA from Indian bovine samples. Our results represent the first successful extraction and amplification of bovine ancient DNA from India, and thus may pave the road for a better understanding of demographic and historical processes of cattle domestication that has taken place in this region.     

Luminescence dating of bricks from the gothic Saint James Church in Toruń

Saint James Church in Toruń is one of the most important gothic monuments in Poland. The date of the beginning of its construction is known from historical reports but the earlier history of the site remains undiscovered. During the archaeological excavations in years 2010 and 2011 five brick samples were collected for luminescence dating as well as four additional samples from the brick surroundings for the dose rate estimation. The equivalent dose was determined by TL and OSL methods. The TL results differ significantly from the OSL results but the last ones are verified by historical knowledge and radiocarbon dating. Establishing the dose rate from gamma rays needs a special attention because of the complex course of the foundations of the church. The details of the applied approach are presented in the current work. The results obtained indicate that a solid brick construction existed at the site of the presbytery of the Saint James Church before it was build.     

Distinguishing nonhuman predation on birds: pattern of damage done by the white-tailed eagle Haliaetus albicilla, with comments on the punctures made by the golden eagle Aquila chrysaetos

The study presents criteria to distinguish some of the nonhuman predation on birds whose remains may also be found at archaeological sites. Specifically, it deals with fragmentation patterns of bird bones in uneaten food remains of the white-tailed eagle Haliaetus albicilla and discusses perforations in victims' bones done by the white-tailed and golden eagles. The food remains show very low degree of fragmentation; bones of the pectoral girdle and wing predominate while head and leg elements are poorly represented. The proportion of perforated sterna differs between the two species of eagles and it is suggested that the differences are attributed to the species of prey rather than the way of handling them by the raptors.     

Geography of Hyperlinks—Spatial Dimensions of Local Government Websites

The purpose of this paper is to determine whether the connections in cyberspace relate in any way to borders as understood in geographical terms. This goal requires testing Tobler's First Law of Geography. Analyses of hyperlinks come under the domain of webometrics, which seeks to answer the fundamental question: Is it possible to measure the Web? This study identified all websites which have hyperlinked to the websites of local authorities in the region of Lower Silesia. These websites were classified by the geographical location of the entity determining their content and thematic category. On the whole, it can be said that connections in cyberspace largely reflect actual functional borders. However, the main functional node dominating cyberspace is a country's capital.     

Prioritizing Disaster Mapping Tasks for Online Volunteers Based on Information Value Theory

In recent years, online volunteers have played important roles in disaster response. After a major disaster, hundreds of volunteers are often remotely convened by humanitarian organizations to map the affected area based on remote sensing images. Typically, the affected area is divided using a grid‐based tessellation, and each volunteer can select one grid cell to start mapping. While this approach coordinates the efforts of volunteers, it does not differentiate the priorities of different cells. As a result, volunteers may map grid cells in a random order. Due to the spatial heterogeneity, different cells may contain geographic information that is of different value to emergency responders. Ideally, cells that potentially contain more valuable information should be assigned higher priority for mapping. This article presents an analytical framework for prioritizing the mapping of cells based on the values of information contained in these cells. Our objective is to provide guidance for online volunteers so that potentially more important cells are mapped first. We present a method that is based on information value theory and focus on road networks. We apply this method to a number of simulated scenarios and to a real disaster mapping case from the 2015 Nepal earthquake.     

Spatial restructuring of old industrial areas: Polish and former East German experiences

>This paper compares and contrasts the policy initiatives and the likely policy fortunes of two older, and heavily polluted, industrial regions — Upper Silesia in Poland and the Leipzig‐Halle district of the former East Germany. The involvement of local communities in the self‐regulation of structural planning is advocated in favour of state‐regulated planning, a version of which degraded these areas.     

Reconstruction of smelting conditions during 16th- to 18th-century copper ore processing in the Kielce region (Old Polish Industrial District) based on slags from Miedziana Góra,Poland

This study presents the first reconstruction of the smelting conditions in 16th- to 18th-century smelters from Miedziana Góra (Holy Cross Mountains, Poland). Based on geochemical (inductively coupled plasma mass spectrometry/emission spectrometry, X-ray fluorescence) and mineralogical analysis (X-ray diffractometry, scanning electron microscopy, electron probe micro-analysis) of historical slags, their chemical/phase composition and the basic smelting parameters (temperature, melt viscosity, and oxygen fugacity) were determined. Due to the differences in chemical and phase composition, slags from different smelting stages have been distinguished: hypocrystalline slags (MG6) from speiss/matte production and glassy (MG1–MG5) from matte conversion. In glassy slags, pyroxenes, quartz/cristobalite grains, and aggregates composed of metallic Cu and PbO are dispersed in the glass. Hypocrystalline slags are composed of wollastonites, anorthites, and metallic Cu. The temperature range at which the slags were formed was from ~1100°C (solidus temperature) to 1150–1200°C (liquidus temperature). The silicate melt's viscosity was from log η = 1.19 to 4.42 Pa s (at 1100–1200°C). The higher viscosity of MG1–MG5 slags indicates that, unlike MG6 slags, they were not formed during gravity separation. Information about the phase composition made it possible to determine the oxygen fugacity in the range of log fO₂ = −4 to −12 atm. High oxygen fugacity indicates the oxidizing nature of the smelting process.
