Modele niepełnosprawności jako determinanty przeobrażeń struktury podażowej rynku turystycznego dostępnego dla osób niepełnosprawnych

The research aims to answer a fundamental question: which of the disability models currently in use is optimal for creating “accessible tourism-oriented” amenities, as well as more detailed problems: (1) what is disability and what determines different disability models? (2) what types of tourism market supply available for the disabled do the different disability models suggest? (3) are the disability models complementary or mutually exclusive? (4) is the idea of social integration and inclusion of people with disabilities (PWD) while on tourist trips supported of the society? Data sources comprise selected literature and results of a survey conducted using the face-to-face method and the SurveyMonkey website from May 2013 to July 2014. The surveyed group included 619 people (82% were Polish, the other 18% were foreigners from: Russia, Germany, Portugal, Slovakia, Canada, Tunisia and the United Kingdom). The research showed that the different disability models – medical, social, geographical and economic – are useful when creating the tourism supply for the PWD. Using the research results, the authors suggested a model of “diversification of tourism market supply structure available for the disabled”, which includes different types of supply – from specialist to universal. This model has practical usage and can help entrepreneurs with the segmentation of tourism offers addressed to the PWD. The work is innovative, both in its theoretical approach (the review of disability models and their practical application in creating tourism supply) and empirical values – it provides current data for the social attitude towards the development of PWD tourism. Especially the presentation of a wide range of perception of disability as well as the simple classification of tourism supply that meets the varied needs of PWD, is a particular novelty of this chapter.

Turystyka i rekreacja a jakość życia mieszkańców Leszna

The quality of life (QOL) is currently one of the main fields of study for researchers around the world. Its complex nature makes it a topic of interest for many different fields, such as philosophy, ethics, medicine, economics, sociology and physical culture sciences. Despite the differences in the way various researches define the QOL, the general agreement is that any measurement of QOL should encompass the following dimensions: objective QOL and subjective QOL (well-being). Particularly noteworthy, for any complex research is the mutual relationship between the QOL and tourism and recreation. The increase of tourism and recreation should entail a simultaneous development of local communities, as emphasized by Crouch and Ritchie this implies that the inhabitants of an area that serves a function of tourism and recreation should profit from the increased number of tourists. This benefits should be reflected in the objective QOL conditions and the subjective sense of satisfaction of the residents. The city of Leszno and it’s tourism and recreation-oriented development strategy were used to form a basis for theoretical study on QOL and to calculate the Tourism-Recreation QOL Index.

Percepcja walorów turystycznych przez osoby niesłyszące na tle słyszącej części społeczeństwa w Polsce

The article aims at showing similarities and differences in the perception of tourist attractions among tourists with and without hearing impairment. The first part depicts perception problems from the theoretical point of view. Complexities of studies on the perception system have been described. The perception itself is channelled via senses, including mainly sight (reception of approximately 87% of outside factors), hearing (7%), smell (3–5%), touch (1–5%) and taste (1%) (Visual Landscape… 1994, after: Pietrzak 2008). The data suggests that people with hearing impairment, owing to dominative position of sight perception and to other senses (except hearing), should perceive outside factors similarly to people with no hearing impairment, also in terms of tourist attractions. Is this really a fact? The attempt to answer this question resulted in conducting questionnaire study among the tourists, both with and without hearing impairment. The data was collected, based on questionnaire study, conducted nationwide in years 2004–2010 among the 292 deaf (for whom Polish Sign Language is the main method of communication) and 1780 people without hearing impairment. The aim of this study was to reveal, if tourists with hearing dysfunction have different tourist preferences than those without any hearing disabilities and to indicate which tourist attractions are the most significant for tourists with hearing impairment. The percentage values and the level of signi-ficance (p), calculated on the basis of Pearson’s chi-square test (with border value of p ≤ 0.05), were used in the analysis It was determined, that in case of perception of natural tourist attractions, there is a major similarity (both, people with and without hearing impairment indicated such attractions as sea, lake, clean natural environment, natural landscape, climate and diversified land relief, including mountains). As far as cultural attractions are concerned, a similarity in perception of both studied groups can also be observed. The most popular attractions include those, which can be perceived with sight: monuments, historic landmarks, museums, open-air museums, places of worship and modern architecture. The biggest differences are related to culture and entertainment, which indicates a social aspect of the disability of people with hearing impairment (a discomfort of being in environ-ment, where sound is the main carrier of information). The conclusions from the conducted analyses are applicative in their nature. They contain hints for tour operators, involved in creating tourist offer for people using Polish Sign Language, taking into account their preferences, perception abilities and ensuring pleasant tourist experience.

Attitudes of Future Tourism Sector Employees Towards Organise Accessible Tourism

The aim of this paper is to show a theoretical approach to the evolution of concepts perceiving disability, taking into account the medical, social, and geographical models, as the basis for the development of principles concerning the organisation of accessible tourism for people with disabilities (PwD). The main research objective was to identify the current attitudes of future, potential employees in the tourism (tourism and recreation students at the time of the study) towards accessible tourism. The study was based on surveys performed in May 2013 at the Adam Mickiewicz University in Poznań (UAM, Poland) and the State University in Irkutsk (ИГУ, Russia), a total sample of 216 people. The main section of the survey contained four questions regarding issues such as: optimal ways to organise tourism products for people with a disability; attitudes towards spending leisure time together with people with a disability; and specific requirements concerning the introduction of various types of improvements in tourism products aimed at people with a disability. In both cases, the results revealed that future tourism employees hold attitudes which are prevailingly open and positive towards the needs of tourists with disabilities. However, the hypothesis that the main factor influencing a reluctance to enter into contact with PwD is a lack of experience in this area, resulting in insufficient knowledge of what conditions the behaviour of PwD was also confirmed. This is a highly significant conclusion which should consider if mandatory educational programmes in the field of tourism and recreation studies are to be improved.

Sedimentary archives of climate and sea-level changes during the Holocene in the Rhone prodelta (NW Mediterranean Sea)

A 7.38 m-long sediment core was collected from the eastern part of the Rhone prodelta (NW Mediterranean) at 67 m water depth. A multi-proxy study (sedimentary facies, benthic foraminifera and ostracods, clay mineralogy, and major elements from XRF) provides a multi-decadal to century-scale record of climate and sea-level changes during the Holocene. The early Holocene is marked by alternative silt and clay layers interpreted as distal tempestites deposited in a context of rising sea level. This interval contains shallow infra-littoral benthic meiofauna (e.g. Pontocythere elongata, Elphidium spp., Quinqueloculina lata) and formed between ca. 20 and 50 m water depth. The middle Holocene (ca. 8.3 to 4.5 ka cal. BP), is characterized, at the core site, by a period of sediment starvation (accumulation rate of ca. 0.01 cm yr−1) resulting from the maximum landward shift of the shoreline and the Rhone outlet(s). From a sequence stratigraphic point of view, this condensed interval, about 35 cm-thick, is a Maximum Flooding Surface that can be identified on seismic profiles as the transition between delta retrogradation and delta progradation. It is marked by very distinct changes in all proxy records. Following the stabilization of the global sea level, the late Holocene is marked by the establishment of prodeltaic conditions at the core site, as shown by the lithofacies and by the presence of benthic meiofauna typical of the modern Rhone prodelta (e.g. Valvulineria bradyana, Cassidulina carinata, Bulimina marginata). Several periods of increased fluvial discharge are also emphasized by the presence of species commonly found in brackish and shallow water environments (e.g. Leptocythere). Some of these periods correspond to the multi-decadal to centennial late Holocene humid periods recognized in Europe (i.e. the 2.8 ka event and the Little Ice Age). Two other periods of increased runoffs at ca. 1.3 and 1.1 ka cal. BP are recognized, and are likely to reflect periods of regional climate deterioration that are observed in the Rhone watershed.

The Ponto-Caspian basin as a final trap for southeastern Scandinavian Ice-Sheet meltwater

This paper provides new data on the evolution of the Caspian Sea and Black Sea from the Last Glacial Maximum until ca. 12 cal kyr BP. We present new analyses (clay mineralogy, grain-size, Nd isotopes and pollen) applied to sediments from the river terraces in the lower Volga, from the middle Caspian Sea and from the western part of the Black Sea. The results show that during the last deglaciation, the Ponto-Caspian basin collected meltwater and fine-grained sediment from the southern margin of the Scandinavian Ice Sheet (SIS) via the Dniepr and Volga Rivers. It induced the deposition of characteristic red-brownish/chocolate-coloured illite-rich sediments (Red Layers in the Black Sea and Chocolate Clays in the Caspian Sea) that originated from the Baltic Shield area according to Nd data. This general evolution, common to both seas was nevertheless differentiated over time due to the specificities of their catchment areas and due to the movement of the southern margin of the SIS. Our results indicate that in the eastern part of the East European Plain, the meltwater from the SIS margin supplied the Caspian Sea during the deglaciation until ∼13.8 cal kyr BP, and possibly from the LGM. That led to the Early Khvalynian transgressive stage(s) and Chocolate Clays deposition in the now-emerged northern flat part of the Caspian Sea (river terraces in the modern lower Volga) and in its middle basin. In the western part of the East European Plain, our results confirm the release of meltwater from the SIS margin into the Black Sea that occurred between 17.2 and 15.7 cal kyr BP, as previously proposed. Indeed, recent findings concerning the evolution of the southern margin of the SIS and the Black Sea, show that during the last deglaciation, occurred a westward release of meltwater into the North Atlantic (between ca. 20 and 16.7 cal kyr BP), and a southward one into the Black Sea (between 17.2 and 15.7 cal kyr BP). After the Red Layers/Chocolate Clays deposition in both seas and until 12 cal kyr BP, smectite became the dominant clay mineral. The East European Plain is clearly identified as the source for smectite in the Caspian Sea sediments. In the Black Sea, smectite originated either from the East European Plain or from the Danube River catchment. Previous studies consider smectite as being only of Anatolian origin. However, our results highlight both, the European source for smectite and the impact of this source on the depositional environment of the Black Sea during considered period.

Safety and risk factors for difficult endoscopist-directed ERCP sedation in daily practice: a hospital-based case-control study

Background: There are limited data concerning endoscopist-directed endoscopic retrograde cholangiopancreatography deep sedation. The aim of this study was to establish the safety and risk factors for difficult sedation in daily practice. Patients and methods: Hospital-based, frequency matched case-control study. All patients were identified from a database of 1,008 patients between 2014 and 2015. The cases were those with difficult sedations. This concept was defined based on the combination of the receipt of high-doses of midazolam or propofol, poor tolerance, use of reversal agents or sedation-related adverse events. The presence of different factors was evaluated to determine whether they predicted difficult sedation. Results: One-hundred and eighty-nine patients (63 cases, 126 controls) were included. Cases were classified in terms of high-dose requirements (n = 35, 55.56%), sedation-related adverse events (n = 14, 22.22%), the use of reversal agents (n = 13, 20.63%) and agitation/discomfort (n = 8, 12.7%). Concerning adverse events, the total rate was 1.39%, including clinically relevant hypoxemia (n = 11), severe hypotension (n = 2) and paradoxical reactions to midazolam (n = 1). The rate of hypoxemia was higher in patients under propofol combined with midazolam than in patients with propofol alone (2.56% vs. 0.8%, p < 0.001). Alcohol consumption (OR: 2.674 [CI 95%: 1.098-6.515], p = 0.030), opioid consumption (OR: 2.713 [CI 95%: 1.096-6.716], p = 0.031) and the consumption of other psychoactive drugs (OR: 2.015 [CI 95%: 1.017-3.991], p = 0.045) were confirmed to be independent risk factors for difficult sedation. Conclusions: Endoscopist-directed deep sedation during endoscopic retrograde cholangiopancreatography is safe. The presence of certain factors should be assessed before the procedure to identify patients who are high-risk for difficult sedation.

Transcriptional profiling in Saccharomyces cerevisiae relevant for predicting alachlor mechanisms of toxicity

Alachlor has been a commonly applied herbicide and is a substance of ecotoxicological concern. The present study aims to identify molecular biomarkers in the eukaryotic model Saccharomyces cerevisiae that can be used to predict potential cytotoxic effects of alachlor, while providing new mechanistic clues with possible relevance for experimentally less accessible eukaryotes. It focuses on genome-wide expression profiling in a yeast population in response to two exposure scenarios exerting effects from slight to moderate magnitude at phenotypic level. In particular, 100 and 264 genes, respectively, were found as differentially expressed on a 2-h exposure of yeast cells to the lowest observed effect concentration (110 mg/L) and the 20% inhibitory concentration (200 mg/L) of alachlor, in comparison with cells not exposed to the herbicide. The datasets of alachlor-responsive genes showed functional enrichment in diverse metabolic, transmembrane transport, cell defense, and detoxification categories. In general, the modifications in transcript levels of selected candidate biomarkers, assessed by quantitative reverse transcriptase polymerase chain reaction, confirmed the microarray data and varied consistently with the growth inhibitory effects of alachlor. Approximately 16% of the proteins encoded by alachlor-differentially expressed genes were found to share significant homology with proteins from ecologically relevant eukaryotic species. The biological relevance of these results is discussed in relation to new insights into the potential adverse effects of alachlor in health of organisms from ecosystems, particularly in worst-case situations such as accidental spills or careless storage, usage, and disposal.

A comparative study of the structural, mechanical and tribological characteristics of TiSiC-Cr coatings prepared in CH4 and C2H2 reactive atmosphere by cathodic vacuum arc

TiSiC-Cr coatings, with Cr and Si as additional elements, were deposited on Si, C 45 and 316 L steel substrates via cathodic arc evaporation. Two series of coatings with thicknesses in the range of 3.6–3.9 μm were produced, using either CH4 or C2H2 as carbon containing gas. For each series, different coatings were prepared by varying the carbon rich gas flow rate between 90 and 130 sccm, while maintaining constant cathode currents (110 and 100 A at TiSi and Cr cathodes, respectively), substrate bias (–200 V) and substrate temperature (∼320 °C). The coatings were analyzed for their mechanical characteristics (hardness, adhesion) and tribological performance (friction, wear), along with their elemental and phase composition, chemical bonds, crystalline structure and cross-sectional morphology. The coatings were found to be formed with nano-scale composite structures consisting of carbide crystallites (grain size of 3.1–8.2 nm) and amorphous hydrogenated carbon. The experimental results showed significant differences between the two coating series, where the films formed from C2H2 exhibited markedly superior characteristics in terms of microstructure, morphology, hardness, friction behaviour and wear resistance. For the coatings prepared using CH4, the measured values of crystallite size, hardness, friction coefficient and wear rate were in the ranges of 7.2–8.2 nm, 26–30 GPa, 0.3–0.4 and 2.1–4.8 × 10−6 mm3 N−1 m−1, respectively, while for the coatings grown in C2H2, the values of these characteristics were found to be in the ranges of 3.1–3.7 nm, 41–45 GPa, 0.1–0.2 and 1.4–3.0 × 10−6 mm3 N−1 m−1, respectively. Among the investigated coatings, the one produced using C2H2 at the highest flow rate (130 sccm) exhibited the highest hardness (45.1 GPa), the lowest friction coefficient (0.10) and the best wear resistance (wear rate of 1.4 × 10−6 mm3 N−1 m−1).

« Nous vivons parmi des Tabors! » Logiques d’ancrage spatial chez les Roumains-Bayashes nord-carpatiques

À l’heure des migrations contemporaines liées au travail, la flexibilité spatiale des groupes tsiganes n’est plus considérée comme une « déviation » par rapport à la sédentarité, paradigme dominant pour penser l’espace. Le « nomadisme » tsigane dévoile aujourd’hui un visage nouveau : celui d’une mobilité de travail complexe qui produit, elle aussi, certaines formes d’ancrage spatial. Dans le champ des études tsiganes, ce sont surtout les diverses trajectoires et pratiques de déplacement des groupes « nomades » qui ont retenu l’attention des spécialistes. Dans cette thèse, nous préférons nous appuyer sur la phénoménologie des formes tsiganes d’ancrage spatial. À partir d’une approche ethnologique directe des 15 communautés roumaines-bayashes de la région des Carpates du Nord, dans l’Ukraine occidentale et au Sud-Est de la Slovaquie, nous interrogeons plus particulièrement le rapport qui existe entre le tabor — terme émique pour désigner les camps tsiganes est-européens — et le concept de territoire. Notre analyse porte notamment sur le tabor en tant que forme de localisation temporaire, de découpage social et culturel de l’espace et ce, dans une perspective qui tient compte des changements que les processus de sédentarisation communiste et postcommuniste lui ont fait subir. De nouvelles logiques spatiales sont mises en oeuvre, c’est pourquoi certains concepts opératoires — plus adaptés aux réalités contemporaines du tabor — sont discutés.
