    Primary objective To assess the extent to which presentation to the individual of images of their own body created during medical imaging procedures increases or decreases health behaviours such as: 1. dietary fat intake; 2. physical activity levels; 3. smoking; 4. alcohol use; 5. damaging exposure to sunlight or other sources of ultraviolet radiation. This will be considered in comparison to the impact of communicating the same findings in a way which does not involve showing the person the source images derived from the imaging procedure (such as solely through oral feedback, or a written report). Secondary objective A secondary objective is to determine the impact of this feedback on consumers': 1. understanding of the relevant condition and of the risk information they have been given; 2. perceived severity and risk of disease; 3. perceived control over the disease risk; 4. perceived effectiveness of the risk-reducing behaviour; 5. emotional response, including general anxiety and condition-specific worry

    Aconitum in Central Europe : from Linnean taxonomy to molecular markers

    Get PDF
    A role of the Linnaean taxonomy in the arising of historical-biogeographical hypotheses is envisioned. The first example concerns the presumed hybrid origin of an Eastern-Sudetic endemic Aconium plicatum subsp. sudeticum. It was described on the basis of a unique character set including glandular hairiness of the indumentum. A PCR-RAPD+ISSR fingerpriting confirmed the supposition based on the morphological analysis. The second example is dealt with the marginal populations. They are of special interest because of the ecological and population genetic phenomena, including genetic drift and subsequent schizoendemism (endemovicarism), a form of the peripatric speciation. Aconitum bucovinense occurs in two marginal, isolated populations in the Western Bieszczady Mts. (E Carpathians). They form a unique morphotype recognized by a taxonomic revision. A PCR-ISSR protocol was used to check a hypothesis on the genetic distinctness of the small, isolated populations. In the effect the lowering by 13% of genetic diversity in the marginal populations, in comparison to the core population, was noted. However, the genetic depauperation was accompanied by the existence of unique bands leading to the distinct genetic stocks in the marginal populations

    Aconitum moldavicum Hacq. (Ranunculaceae) i jego mieszańce w Karpatach i przyległych obszarach

    Herbarium and field studies on Aconitum moldavicum Hacq. in Poland, Ukraine Romania, and partially in Slovakia, were carried out. The species consists of two geographical races circumscribed in the rank of subspecies: subsp. hosteanum (Schur) Graebn. et P. Graebn. and subsp. moldavicum. The pattern of geographical distribution confirms Szafer’s (1930) hypothesis on the eastern Podolo-Volhynian glacial refugium, and the Western Carpathian refugium of the species. The common occurrence of the hybridogenous morphotypes A. m. subsp. hosteanum × subsp. moldavicum in the Małopolska Upland is elucidated by a migratory hypothesis. Other taxa distinguished are putative hybrids scattered across the Carpathians in the sympatric areas of their presumed parents. The key for determination of supraspecific taxa and their hybrids is provided

    Perception of Complexity Area in Management–an Exploratory Study in Poland

    Get PDF
    The purpose of this article is presentation theoretical and empirical analysis about complexity perception in organization. We propose following thesis: "perception of complexity in company is possible by separating complexity levels of particular areas of company activity". Taking into account the general aspect of perception and complexity perception in management to the understanding this concept we use the Cynefin model. We accept the assumption that the recognition complexity levels in selected areas create value in decision making processes. Theoretical considerations are supplemented by results of the study in 157 Polish SMEs. The study was conducted in May 2015

    Podejmowanie ryzyka jest kluczową cechą przedsiębiorczości i rozwoju biznesu. Niedostateczne zarządzanie ryzykiem biznesowym często prowadzi do utraty konkurencyjności w wyniku porażki biznesowej, a przeciwieństwie do sytuacji, gdy ryzyko jest skutecznie zarządzane - wpływa na poprawę trwałości biznesu. Celem badań było wskazanie wiodących koncepcji i trendów w studiach dotyczących problematyki podejmowania ryzyka (risk-taking) w obszarze zarządzania przy wykorzystaniu analizy sieci współwystępowania słów kluczowych. Do mapowania wiedzy w tym zakresie wykorzystano metodę analizy bibliometrycznej. Przeanalizowano 2912 rekordów z bazy danych Scopus odnoszących się do problematyki podejmowania ryzyka w badaniach z zakresu zarządzania z wykorzystaniem oprogramowania VOSviewer. W szczególności przeprowadzono analizę sieci oraz współwystępowania słów kluczowych w celu wizualizacji danych, tematów i trendów badawczych w zakresie podejmowania ryzyka w kontekście zarządzania.Risk-taking is a pivotal feature of entrepreneurship and business development. Poor management of business risk often leads to the loss of competitiveness with the consequence of business failure, and in contrast, it improves business sustainability when risks are managed effectively. The aimof thisresearch is to identify leading concepts and trends in research on risk-taking in organizationalmanagement researchby network analysis of keywords co-occurrence. Mapping knowledge domain was used as a useful method in bibliometrics. We analyzed 2912 records from Scopus database to risk-taking in organizational management research with the help of VOSviewer software tool. In particular, keywords co-occurrence analysis to visually explore knowledge bases, topic distribution, research fronts and research trends in the field of risk-taking research in a management context were adopted

    A phenetic study on Aconitum ×hebegynum DC. (Ranunculaceae) in the Eastern Carpathians

    The aim of the study was to re-evaluate the taxon limits of the putative hybrid A. ×hebegynum (A. degenii × A. variegatum). The nothospecies was described on the specimen originated from a region of the Swiss Alps. Its occurrence in the Eastern Carpathians is controversial since one of the putative parents A. variegatum is extremely rare there. A phenetic analysis using quantitative and qualitative floral and leaf morphology characters in 159 herbarium specimens (OTUs) of Aconitum sect. Aconitum ser. Variegata (A. variegatum), ser. Toxicum (A. degenii and A. lasiocarpum and putative hybrid A. ×gayeri) and nser. Toxigata (A. ×hebegynum) from the Eastern Carpathians was carried out. The analyses included Detrended Correspondence Analysis (DCA), Canonical Correspondence Analysis (CCA), Monte Carlo permutation tests, and description statistics. This confirmed the intermediate position of the nothospecies in a morphospace delimited by the putative parents. One of the morphotypes showed introgression towards species of the ser. Toxicum. The other, relatively rare morphotype , was similar to that occurring in the Alps. The Helmet Index of the nothotaxon was exactly between the values found for the putative parents. The findings did not directly point to the existence of the genetic hybrid in the Eastern Carpathians; more molecular DNA and cytogenetic data are needed. They pointed to the existence of distinct morphotypes which, in the case of the rejection of the hypothesis of nothotaxon existence in the region, should be circumscribed in a low-rank taxon within A. degenii

    Greek landscapes through the spectrum of crisis. An ethnographic approach to perceptions and meanings of insular landscape in times of recession

    Get PDF
    The Greek crisis in 2010 was a rupture spread across all aspects of the country’s social milieu causing a discontinuity in its evolutionary course. This abrupt shift of society was transmitted to its produced space, namely landscape, through the changes in institutional structures, livelihood and both individual and collective cognition. My thesis’ aim is to examine the interplay between landscape perception and spatial practice within the emerged reality of crisis. I focused on the crisis impact upon two interconverted phenomena, the way people perceive and experience their landscapes and the way they act upon them. The main interest was the process they (perception and practice) inform each other by reciprocal reactions, producing and reproducing the landscape. The spotlight was on landscapes that are both rural and tourist, on the premise that Greece, without an industrial economy, has been promoting agriculture and tourism as the crisis exodus plan, —both significant factors of landscape change. My research centred on the island of Naxos, where agriculture and tourism have an equal share in local life and economy, defining the island’s landscape; also, tourism is not overdeveloped like in adjacent islands. In my thesis, landscape is construed as Lefebvre’s spatial triad (1991) of perceived, conceived and lived: (society’s) spatial practice, (experts’) representations of space and (users’) representational spaces. On this basis, I aimed to explore the Naxiótes’ perceptions of their landscapes, their assigned meanings and their translation into landscape practice and impact, within the social context of crisis. My theoretical apparatus was Moscovici’s theory of social representations (1963) assisted by Vaisey’s dual process model of culture in action (2009). I employed ethnographic methods: a six-month stay on site as a marginal native in 2013, gathering data via participation, observation, in-depth interviews (unstructured, go-along, casual individual and group conversations) and local media. In addition, I spent two weeks on the island in 2017, for a follow-up, to add a temporal aspect to my research. My field experiences were also a vital part of my research, hence I incorporated them in my thesis. Data analysis unveiled three groups of social representations that feed into landscape perceptions and meanings: attachment, production and relations. Attachment included topophília, connection to the land and local identity; production consisted of self-sufficiency, entrepreneurship and short-termism; kinship, collectivity and conflict were under relations. Common among all groups was the crisis representation in 2013: the island’s immunity to it as no effect had endured. This narrative was reversed in 2017 among the farming and tourism stakeholders, but not the administrative ones. The umbilical cord to their tópos, as home, roots and identity, was broken by escapism. Self-sufficiency as a recipe for entrepreneurship and success was mutated into a survival path. So did short-termism, by converting from a representation of otherness to an open life strategy. Relation dynamics exhibited tension too, predominantly the representation of conflict. In contrast, kinship and collectivity remained as significant as in 2013. A distinct outcome that emerged from my analysis above was the discrepancies between people’s verbal accounts and habitual practices, which I discussed through Vaisey’s heuristic. The social representations that I identified as informative to the meaning the Naxiótes assign to their landscape, were forced into a transformative process by the crisis. People’s discursive consciousness (justification) had adapted to the new reality, however, their practical consciousness (motivation) was yet to attune. Their landscape perception has been changing, but not their landscape practice; yet
