Using keywords to analyze conflicts in doctor-patient consultations
No full textThis paper focuses on the function of conflict prevention performed by keywords and key-expressions within medical consultations.
Doctor-patient interaction within medical consultations can be interpreted as a problem-solving discussion, as it is oriented to the solution of a certain health problem. As such, medical consultations are based on an argumentative discussion, in which, roughly speaking, both parties try to reason together in order to find a solution for the patient s health problem. In this sense, a non-mixed dispute (van Eemeren and Grootendorst 2004) often arises, in which doctor and patient discuss a standpoint, normally advanced by the doctor, about the patient s diagnosis or therapy.
Problem-solving, however, is not the only possible interaction scheme (Rigotti and Rocci 2006) that can be involved in doctor-patient consultations. Indeed, other more confrontational interaction schemes are possible, which may also tend to real controversies; these cases are often triggered by the asymmetry of competences and knowledge which is typical of the relationship between doctors and patients. Such situations, of course, affect the quality of the consultation, because the issue at stake ceases to be the patient s health, and becomes the relationship between the patient and the doctor (in terms of trust, reliability, etc.). Ultimately, this may have negative effects on the patient s health and, thus, more in general, may contradict the raison d être of the health system. Thus during the medical consultation conflicts need to be avoided both by doctor and patient.
The choice of keywords and key-expressions appears to be a crucial step within a strategy of conflict prevention . In fact, thanks to their close link to the relevant endoxa, their ability to trigger inferences, and their centrality within the argumentative structure of persuasive texts, keywords can be very important tools in the creation of emotive arguments and the prevention of conflict. Relying on examples from real-life consultations, this paper shows how keywords and key-expressions realize this function

Iridomyrmex bigi is a very odd-looking Iridomyrmex: the combination of the very large eye, pointed node and the general confinement of the erect setae to the anterior margin of the antennal scape make it impossible to confuse this with any other ant in the genus. However, clypeal and mesosomal characters and preliminary molecular data place this ant close to the meat ants (I. purpureus species-complex), albeit as a sister to this complex. Shattuck (1993b) separated the form I. variscapus from I. bigi on the basis of the paler ground colour of the head and mesosoma and the colour of the scape in workers. However, when the workers from these two taxa used in the revision of the I. purpureus group were revisited in the current project, the variability in colour was found to be in conformity with intraspecific variation seen in other Iridomyrmex species. The centre of the antennal scape is much lighter than its edges in both taxa, and the flagellum is generally paler than the scape. The workers of I. variscapus, all of which come from a single nest in Sandringham, Queensland, share the same structural and setae patterns as I. bigi, and the morphometric measurements and indices used by Shattuck all overlap with those of I. bigi. Iridomyrmex variscapus therefore becomes a junior synonym of I. bigi in this monograph. This appears to be a rare species, and apart from one worker (without collection data) supplied by A. Andersen, no additional material has come to light since Shattuck’s (1993b) revision.Published as part of Heterick, Brian E. & Shattuck, Steve, 2011, Revision of the ant genus Iridomyrmex (Hymenoptera: Formicidae) 2845, pp. 1-174 in Zootaxa 2845 (1) on pages 51-52, DOI: 10.11646/zootaxa.2845.1.1, http://zenodo.org/record/528781
Dialogical functions of metaphors in medical interactions
No full textThis paper proposes a method for analyzing the dialogical functions of metaphors in communicative interactions, and more specifically in the context of medical interviews. The dialogical goals proposed and pursued by the interlocutors are coded using a coding scheme that captures seven mutually exclusive categories of dialogical moves. The functions of the moves, including metaphors, can be identified and correlated with other variables relevant to the type of communication under analysis. The coding scheme is used to analyze a corpus of 39 interactions between healthcare providers and patients affected by Type 2 diabetes. The exploratory quantitative analysis, for the purpose of determining the different distributions of metaphor uses between patients and providers, is combined with qualitative analysis in which the thematic areas of the metaphors are considered. The findings show how patients and providers use metaphors for pursuing different dialogical goals and meeting distinct communicative needs
Raman spectroscopy as a tool for provenancing black limestones (bigi morati) used in antiquity
No full textAmong precious stones used in antiquity, bigi morati stand out for their importance. They consist in black limestones mainly employed in sculptures and architectural heritages and quarried from several sites through the Mediterranean area. Their provenance is difficult to assess due to their similar appearance to the naked-eye observation and the possible confusion with black marbles (i.e., bigi antichi). Classical methods used for studying ancient marbles, such as minero-petrographic and stable isotopes analyses (δ13C and δ 16O), resulted to be powerful in provenancing these black lithotypes. However, these methods are microdestructive and cannot be always applied in the case of precious artefacts for which sampling is not allowed. Bearing carbonaceous matter conferring them the typical black-dark grey colour, Raman spectroscopy might support studies on these limestones, bringing important information about the structural state of organic/carbonaceous matter and their geological evolution. In this study, the potential of Raman spectroscopy in determining geological and geographic provenance of bigi morati was tested on quarry samples from six among the most famous ancient exploitation sources. The obtained results demonstrated that the use of Raman parameters typical of low-ordered carbon matter is an effective tool in discriminating provenance. Moreover, the laboratory-based approach lays the groundwork for future development and validation of the method for in situ measurements on artefacts by using portable equipment

Soil erosion in the Apennines is quite a relevant issue, being a cause of land degradation and reducing the land available to farming. Mountain areas abandonment worsened landscape situation, because of the lack of erosion direct and indirect control.
Estimates of soil erosion activity in a mountain basin are usually made with a significant degree of uncertainty, because usually few data are available to calibrate erosion models or to directly estimate eroded soil amount, thus leading to inability of taking decision in conservation policies.
In order to evaluate the suspended sediment yield (SSY) carried by the Gaiana torrent, a ~9 km2 basin in the Bologna Apennines, we applied a very simple linear model previously built on a geomorphologically similar watershed nearby, which has a very large SSY dataset. This model estimates average SSY from the maximum rainfall intensity on a storm event basis: the simplicity of the model allowed its application on scarcely gauged basins, where precipitation is the main erosive agent, giving reasonable estimates of soil loss.
According to the philosophy behind this approach, we applied the USLE model to the Gaiana catchment, in order to have a further estimate of the order of magnitude of the sediment yield and to test our methodology. We also realized a chart of geomorphology and soil erosion by air photo interpretation, in order to be able to locate the source areas of sediment production. Furthermore, a river monitoring station along with a water samples has been installed at the Gaiana basin outlet. The few collected data since December 2004 have been employed to further verify the linear model efficiency. GIS analysis has been fundamental for extracting USLE factor from the digital elevation model of the basin, and to analyse vegetation cover and geomorphology of the Gaiana basin, as well as for air photo elaboration
The power of Words : deliberation dialogue as a model to favor patient engagement in chronic care
No full textThe concept of patient engagement is attracting growing attention from scholars working on doctor-patient interactions. It refers to the condition in which patients are fully aware of their medical condition and willing to be active both in the relationship with their caregivers and towards the health care institutions. However, the operative steps necessary to achieve patient engagement have not yet been fully described. This chapter focuses on the communicative dimension of engagement. Communication is shown to be a pivotal means to improve patient self-efficacy and commitment, both fundamental components of engagement. In particular, the authors take a closer look at the process of decision making in chronic care settings, and propose a normative model to analyze and evaluate the quality of decision making in consultations. It is argued that the model can also be used as a blueprint to create training materials for clinicians
Discrete fracture network model of the vapor zone leakages at the Copahue geothermal field
No full textThe volcano-hosted geothermal system of Copahue is one of the most promising resources of renewable energy in Argentina. It is driven by a layered reservoir composed of a steam cap above a deep liquid-dominated reservoir. We study the surficial leakages of the shallow steam zone by performing a discrete fracture network model and a 3D forward strain-stress model of the upper caprock unit. The hydrothermal zones linked to steam cap leakages are subordinated to deep-rooted N60-striking faults. Associated damage zones exhibit higher values of fracture intensity, vertical and anisotropy of permeability than the host rocks. Joints and cross-joints likely control leakage zones, where the formers are subject to high dilation tendency. The Anfiteatro monocline might constitute the northwestern boundary of the shallow steam zone. Variations of H2O–CO2 ratio, helium isotopic signature, and CO2 between hydrothermal zones are explained in terms of petrophysical properties of the upper ignimbrites and changes in their structural control. Our results suggest that the upper caprock ignimbrite avoids the decompression of the reservoir because it provides the low fractured and low permeability layer that seals the geothermal system; conversely, ignimbrites affected by the extensional faults system enhance the shallow vapor zone given its high fracture density and permeability.Fil: Barcelona, Hernan.
