Taphonomic analysis of leporid remains obtained from modern Iberian lynx (Lynx pardinus) scats

Distinguishing leporid bones accumulated by diurnal raptors, owls, mammals and humans is essential to understand not only past human subsistence activities but also past ecology. This is particularly relevant in Iberian Palaeolithic sites where leporid remains usually constitute the most abundant taxon. As far as terrestrial mammal carnivores are concerned, the Iberian lynx (Lynx pardinus) would be the main leporid predator in the Iberian Peninsula. Up until now its contribution as a rabbit bone accumulator in archaeological sites has never been properly assessed. In order to investigate the taphonomic signature of this predator the analysis of 33 samples of modern Iberian lynx scats was carried out. Results show that leporid remains consumed by this carnivore appear very fragmented and exhibit a strong degree of corrosion digestion. Cranial elements are most abundant followed by long bones. Whereas there seem to be clear differences in relation to breakage and digestion alteration caused by owls, some of the patterns obtained are closest to those established with diurnal raptors.     

Structural Integrity of Stone Blocks From Charles Bridge in Prague

The Charles Bridge is the oldest, still-standing gothic bridge that crosses the Vltava River in Prague and up to now has belonged among the most sought-after historical monuments in the Czech Republic. The bridge has been repeatedly damaged due to floods and has been repaired several times. In the reconstructions, damaged sandstone blocks were substituted in facing. This experimental study focused on nonlinear ultrasonic spectroscopy for testing stone blocks that were extracted from the historical bridge structure. The objective of these experiments was verifying whether the methods can be applied to evaluating the internal structure of blocks, which are built-in in the structure in situ. Intact-structure blocks, blocks that had been repaired in the past, and damaged-structure blocks were measured. Two methods of nonlinear ultrasonic spectroscopy were applied—the method with single harmonic ultrasonic signal and with two harmonic ultrasonic signals. Measurement results of both applied methods proved resulting parameters correlation with block structure integrity quality.     

Seismic Vulnerability Assessment of the Urban Building Environment in Nablus,Palestine

ABSTRACT

This article describes a specifically developed framework to produce a seismic physical vulnerability model of residential buildings in Nablus (Palestine) within the European project SASPARM2.0. Based on the structural taxonomy of the territory, two different forms were defined to collect geometrical and structural data of buildings by different stakeholders (citizens and practitioners). This data was then employed to produce fragility curves using the mechanics-based procedure SP-BELA. To estimate seismic risk, the developed fragility model was combined with a hazard curve for the corresponding location. The described procedure is implemented in a WebGIS platform that allows to georeference and assess the surveyed buildings and define retrofitting strategies. Finally, the article carries out a comparison between the fragility curves of buildings in Nablus and the ones calculated for similar building typologies within a UNDP Jordan project aiming at the integrated risk assessment in Wadi Musa and surroundings.     

Attempts at thermoluminescence dating of fired materials from the Przeworsk Culture settlements

The thermoluminescence (TL) dating method has a significant measurement error margin reaching almost 10%. Due to this fact it could be considered as little effective in case of such sites from the Roman period as burial grounds with many artefacts useful for archaeological dating. However, for many settlements from this period, where pottery is the only kind of artefacts, the TL method can give notable results. The main purpose of the study was to make an attempt at TL dating of pottery and clay daub samples from the Nieszawa Kolonia and Kręcieszki sites and to compare the obtained dates with the results of archaeological dating of selected features from the Przeworsk Culture settlements. In the Kręcieszki site the fragments of burnt clay daub were dated by the TL method for the first time in the Lublin laboratory. It turned out that clay daub is an equally good dating material as pottery. It can be found that the TL dating of pottery from Nieszawa Kolonia confirms two stages of settlement. The first settlement stage is related to the phases B2-B2/C1-C1a of the Roman period, i.e. from the beginning of the 2^nd to the beginning of the 3^rd century. The second group of TL dates corresponds to the phases C2D that is to the second stage of settlement, from the second half of the 3^rd century to the half of the 5^th century AD. The results of TL dating of pottery and clay daub in the Kręcieszki site are rather similar and correspond to the phase B1/B2 of the period of Roman influence, determined from pottery style, but can also indicate the phase B2/C1.     

Tourism in a nature-based destination: the human versus the ecological perspectives

In the tourism studies literature, wilderness has been addressed from two perspectives. From the first, human, perspective wilderness is a social, subjective construction that exists only in the mind of its users. From the second, ecological, perspective it is a material, objective reality. Here, we compare these two perspectives based on data collected in one of Poland's most popular nature-based destinations, The Great Masurian Lakes region, and develop a methodological framework which would operationalise this comparison and make it measurable. The research approach combined a survey of tourists and mapping of natural features. The data was analysed, first, to verify whether stated preferences regarding nature and the natural features surrounding tourist accommodation were coherent; this resulted in the construction of a Coherence Index (CI). Second, we analysed how stated preferences with respect to nature were linked to outdoor recreational activities; this was measured by a Nature Cruciality Index (NCI). Finally, both indexes were mapped and their spatial distributions were analysed. The findings showed that the subjective, social construction of wilderness does not always correspond to objective reality. Although tourists declared natural environment to be very important to them, in some cases the analysis found a lack of consistency between expressed preferences and the natural features found around accommodation. The phenomenon was mainly found in towns, where tourists were most nature-indifferent. Moreover, they were not interested in activities with high NCI. In some cases, however, the two perspectives were coherent, especially among nature-oriented tourists who stayed near lakes and those who stayed in villages (who were most conscious of their choices). Tourists who stayed near lakes undertook the most nature-crucial activities. These findings can be used to enhance local planning, management and marketing strategies for nature tourism.     

Key variables for developing integrated rural tourism

Considering how important tourism development is as an element of economic recovery in rural areas, one of its objectives should be sustainability. The starting point must therefore be the existence of partnerships and cooperation between stakeholders. Such cooperation would enable the integration of tourism development through the endogeneity, complementarity, and embeddedness of the resources and the empowerment of the residents. The objective of this research is to determine the basic types of relationships to be developed in order to achieve integrated rural tourism. Initially, we verify the variables involved in integrated rural tourism by determining the measurement models, and subsequently we propose a model that reflects the relationships between the variables under study. Our research shows that there must be two types of collaboration between stakeholders. First, there must be collaboration to develop a tourism product, and second, there must be collaboration to provide adequate information about the existing tourism activities. Due the nature of tourism, various types of businesses must work together, but if information is not subsequently provided about the product, then tourism cannot develop as desired. Collaboration as a whole also favours the development of rural tourism in which tourism activities complement the traditional activities of an area, consequently increases the embeddedness of the product and the endogeneity of the resources. Furthermore, the opinions of the various stakeholders in tourism development must be taken into account, especially the residents, which takes place through empowerment. Finally, collaboration means that residents and tourists must coexist and come into contact, therefore sharing public services and entertainment and leisure locations. All the aforementioned factors consequently provide the basis for integrating the rural tourism that is developed in an area, which will favour the economic, sociocultural, and environmental sustainability of that area.
