Sobre "fenomenología" y "hermenéutica". Aproximación a los conceptos de empatía y comprensión.

El trabajo parte de una consideración de la hermenéutica como filosofía que cuestiona el sentido de la experiencia en la configuración del mundo histórico-social e intenta mostrar conexiones entre el desarrollo de esta corriente y posibles aportaciones de la Fenomenología.El objetivo de la investigación es analizar la presencia de algunos motivos fenomenológicos en las actuales propuestas de superación del planteamiento hermenéutico elaborado por Gadamer y de raíz heideggeriana, atendiendo a algunos de los debates a los que ha dado lugar y destacando el interés del tema de la empatía en relación con el de la comprensión. Estas nociones indicarán formas específicas de abordar el problema de la experiencia en el contexto intersubjetivo del mundo social.

Unnatural Mothers, Mothering Unnaturally: Technologies of Reproduction and the Politics of Maternity in Hiromi Goto's "Hopeful Monsters"

Through scientific discourse and reproductive technologies, the reproductive body and the maternal body continue to be constructed as ‘natural’. At the same time,these technologies have begun to blur the boundaries between what is consideredan acceptable reproductive body, and consequently an acceptable maternal body,and an unnatural or a socially undesireable one. As science purports to offerwomen greater control over how and when they choose to procreate, through methods which range between delaying or eliminating the possibility of contraception to those which extend the possibility of conception to postmenopausal or infertile women, these same procedures raise questions about thenature and ‘naturalness’ of reproduction. Added to these concerns are thesuitablility of the reproductive body as a maternal body. Consequently, and moreand more frequently, bodies which defy ideals about maternity and motherhoodemerge, and questions about what it means to mother are raised. Bodies whichcontest the construction of motherhood as natural are frequently represented asmonstrous or freakish, and the debate between science and nature is heightened.Hiromi Goto’s short story ‘Hopeful Monsters’ resists the construction of the‘natural’ maternal body by highlighting the way in which women’s bodies areshaped by scientific discourse. In turn, images of ‘monstrous’ mothers emerge andare challenged, suggesting the need to reimagine what it means to mother and whatit means to be a mother. Through reading a selection of the stories this paper willinterrogate possible alternatives to constructions of the ‘natural’ maternal body and motherhood, suggesting that the Goto’s ‘monsters’ are perhaps only monstrous as a result of scientific discourse which constructs them as such.

Origin of CO2 and carbonate veins in mantle-derived xenoliths in the Pannonian Basin

The origin and evolution of CO2 inclusions and calcite veins in peridotite xenoliths of the Pannonian Basin, Hungary, were investigated by means of petrographic investigation and stable isotope analyses. The fluid inclusions recovered in paragenetic olivine and clinopyroxene belong to distinct populations: type A (texturally early) inclusions with regular shapes (often with negative crystal forms) forming intragranular trails, type B (texturally late) inclusions defining randomly oriented trails that reach grain boundaries Type B inclusions are often associated with silicate melt (type C) inclusions Stable carbon isotope compositions in inclusion-hosted CO2 were obtained by vacuum crushing followed by conventional dual inlet as well as continuous flow mass spectrometry in order to eliminate possible lab artifacts. Olivines, clino- and orthopyroxenes of the host peridotite have oxygen isotope compositions from 5.3 to 6.0 parts per thousand (relative to V-SMOW). without any relationship with xenolith texture. Some of the xenoliths contained calcite in various forms veins and infillings in silicate globules in veins, secondary carbonate veins filling cracks and metasomatic veins with diffuse margins The former two carbonate types have delta C-13 values around -13 parts per thousand (relative to V-PDB) and low Sr contents (<05 wt %), whereas the third type,veins with high-temperature metasomatic features have a delta C-13 value of -5 0 parts per thousand and high Sr contents up to 34 wt.% In spite of the mantle-like delta C-13 value and the unusually high Sr content typical for mantle-derived carbonate, trace element compositions have proven a crustal origin. This observation supports the conclusions of earlier studies that the carbonate melt droplets found on peridotite xenoliths in the alkaline basalts represent mobilized sedimentary carbonate. The large delta C-13 range and the C-12-enrichment in the carbonates can be attributed to devolanlization of the migrating carbonate or infiltration of surficial fluids containing C-12-rich dissolved carbon Carbon isotope compositions of inclusion-hosted CO2 range from -17 8 to -4.8 parts per thousand (relative to V-PDB) with no relation to the amount of CO2 released by vacuum crushing. Low-delta C-13 values measured by stepwise heating under vacuum suggest that the carbon component is pristine and not related to surficial contamination, and that primary mantle fluids with delta C-13 values around -5 parts per thousand were at least partly preserved in the xenoliths Tectonic reworking and heating by the basaltic magma resulted in partial CO2 release and local C-13-depletion.

Constraining 3-D electrical resistance tomography with GPR reflection data forimproved aquifer characterization

Surface-based ground penetrating radar (GPR) and electrical resistance tomography (ERT) are common tools for aquifer characterization, because both methods provide data that are sensitive to hydrogeologically relevant quantities. To retrieve bulk subsurface properties at high resolution, we suggest incorporating structural information derived from GPR reflection data when inverting surface ERT data. This reduces resolution limitations, which might hinder quantitative interpretations. Surface-based GPR reflection and ERT data have been recorded on an exposed gravel bar within a restored section of a previously channelized river in northeastern Switzerland to characterize an underlying gravel aquifer. The GPR reflection data acquired over an area of 240×40 m map the aquifer's thickness and two internal sub-horizontal regions with different depositional patterns. The interface between these two regions and the boundary of the aquifer with then underlying clay are incorporated in an unstructured ERT mesh. Subsequent inversions are performed without applying smoothness constraints across these boundaries. Inversion models obtained by using these structural constraints contain subtle resistivity variations within the aquifer that are hardly visible in standard inversion models as a result of strong vertical smearing in the latter. In the upper aquifer region, with high GPR coherency and horizontal layering, the resistivity is moderately high (N300 Ωm). We suggest that this region consists of sediments that were rearranged during more than a century of channelized flow. In the lower low coherency region, the GPR image reveals fluvial features (e.g., foresets) and generally more heterogeneous deposits. In this region, the resistivity is lower (~200 Ωm), which we attribute to increased amounts of fines in some of the well-sorted fluvial deposits. We also find elongated conductive anomalies that correspond to the location of river embankments that were removed in 2002.

Londres, terra promesa: l'emigració de joves universitaris titulats catalans a Londres

L’alta taxa d’atur juvenil a Catalunya i la precarització persistent del mercat laboral per als joves, han provocat que molts d’ells es plantegin marxar a l’estranger per a provar sort. Segons l’INE, al 2012 van emigrar 10791 catalans i el 35,7% són joves d’entre 16 i 34 anys. El Regne Unit va ser la tercera destinació preferida, amb 958 catalans emigrants reconeguts. La globalització ha difuminat les fronteres i ha obert els horitzons a empreses i treballadors. Les experiències internacionals són cada cop més necessàries si volem formar part d’aquest món, però tenen les seves contrapartides. La present investigació estudia el cas de 10 joves catalans amb titulacions universitàries que han marxat a Londres a la recerca d’aquesta experiència internacional, tot desitjant assentar les bases d’una carrera professional exitosa. El focus d’estudi és conèixer les motivacions de l’emigració que han trobat a la ciutat anglesa i quines són les expectatives de futur

Confined brownian ratchets

We analyze the dynamics of Brownian ratchets in a confined environment. The motion of the particles is described by a Fick-Jakobs kinetic equation in which the presence of boundaries is modeled by means of an entropic potential. The cases of a flashing ratchet, a two-state model, and a ratchet under the influence of a temperature gradient are analyzed in detail. We show the emergence of a strong cooperativity between the inherent rectification of the ratchet mechanism and the entropic bias of the fluctuations caused by spatial confinement. Net particle transport may take place in situations where none of those mechanisms leads to rectification when acting individually. The combined rectification mechanisms may lead to bidirectional transport and to new routes to segregation phenomena. Confined Brownian ratchets could be used to control transport in mesostructures and to engineer new and more efficient devices for transport at the nanoscale.

Phylogenetics of Olea (Oleaceae) based on plastid and nuclear ribosomal DNA sequences: tertiary climatic shifts and lineage differentiation times.

BACKGROUND AND AIMS: The genus Olea (Oleaceae) includes approx. 40 taxa of evergreen shrubs and trees classified in three subgenera, Olea, Paniculatae and Tetrapilus, the first of which has two sections (Olea and Ligustroides). Olive trees (the O. europaea complex) have been the subject of intensive research, whereas little is known about the phylogenetic relationships among the other species. To clarify the biogeographical history of this group, a molecular analysis of Olea and related genera of Oleaceae is thus necessary. METHODS: A phylogeny was built of Olea and related genera based on sequences of the nuclear ribosomal internal transcribed spacer-1 and four plastid regions. Lineage divergence and the evolution of abaxial peltate scales, the latter character linked to drought adaptation, were dated using a Bayesian method. KEY RESULTS: Olea is polyphyletic, with O. ambrensis and subgenus Tetrapilus not sharing a most recent common ancestor with the main Olea clade. Partial incongruence between nuclear and plastid phylogenetic reconstructions suggests a reticulation process in the evolution of subgenus Olea. Estimates of divergence times for major groups of Olea during the Tertiary were obtained. CONCLUSIONS: This study indicates the necessity of revising current taxonomic boundaries in Olea. The results also suggest that main lines of evolution were promoted by major Tertiary climatic shifts: (1) the split between subgenera Olea and Paniculatae appears to have taken place at the Miocene-Oligocene boundary; (2) the separation of sections Ligustroides and Olea may have occurred during the Early Miocene following the Mi-1 glaciation; and (3) the diversification within these sections (and the origin of dense abaxial indumentum in section Olea) was concomitant with the aridification of Africa in the Late Miocene.

Specificity of psychosis, mania and major depression in a contemporary family study.

There has been increasing attention to the subgroups of mood disorders and their boundaries with other mental disorders, particularly psychoses. The goals of the present paper were (1) to assess the familial aggregation and co-aggregation patterns of the full spectrum of mood disorders (that is, bipolar, schizoaffective (SAF), major depression) based on contemporary diagnostic criteria; and (2) to evaluate the familial specificity of the major subgroups of mood disorders, including psychotic, manic and major depressive episodes (MDEs). The sample included 293 patients with a lifetime diagnosis of SAF disorder, bipolar disorder and major depressive disorder (MDD), 110 orthopedic controls, and 1734 adult first-degree relatives. The diagnostic assignment was based on all available information, including direct diagnostic interviews, family history reports and medical records. Our findings revealed specificity of the familial aggregation of psychosis (odds ratio (OR)=2.9, confidence interval (CI): 1.1-7.7), mania (OR=6.4, CI: 2.2-18.7) and MDEs (OR=2.0, CI: 1.5-2.7) but not hypomania (OR=1.3, CI: 0.5-3.6). There was no evidence for cross-transmission of mania and MDEs (OR=.7, CI:.5-1.1), psychosis and mania (OR=1.0, CI:.4-2.7) or psychosis and MDEs (OR=1.0, CI:.7-1.4). The strong familial specificity of psychotic, manic and MDEs in this largest controlled contemporary family study challenges the growing assertion that the major types of mood disorders are manifestations of a common underlying diathesis.

Se_nos gener@ mujeres La construcción discursiva del pecho femenino en el ámbito médico

El objetivo de este artículo es reflexionar sobre el impacto de los mandatos de género en los cuerpos de las mujeres en el contexto biomédico. Exploramos cómo se construye discursivamente la mamoplastia en tres grupos de mujeres: que han padecido cáncer de pecho, trans y que se intervienen por motivos estéticos. Mediante el análisis del discurso estudiamos cómo profesionales de la salud especialistas en los tres casos elaboran la distinción entre ellos, cómo otorgan diferentes grados de legitimidad a la demanda y cómo justifican si su coste se debe cubrir públicamente. Resultado de este análisis detectamos que se establecen dos fronteras entre los cuerpos susceptibles de recibir esta intervención: una relativa a la necesidad y otra a la legitimidad de la demanda.

Tourism destination zoning in rural regions: a consumer-based approach in Terres de l’Ebre

This document puts into question the conventional way of delineating tourism destinations. It intends to show a model of spatial analysis, to find new interpretations of the reality, more balanced and more optimized, in comparison with other territorial views most of them based on administrative boundaries. This paper portrays a methodological exercise that aims to structure tourism geographies into new tourism areas on the basis of visitor’s consumption patterns, which would be better fitted to the needs of tourist demand

Predictive analysis and mapping of indoor radon concentrations in a complex environment using kernel estimation: an application to Switzerland.

PURPOSE: The aim of this study was to develop models based on kernel regression and probability estimation in order to predict and map IRC in Switzerland by taking into account all of the following: architectural factors, spatial relationships between the measurements, as well as geological information. METHODS: We looked at about 240,000 IRC measurements carried out in about 150,000 houses. As predictor variables we included: building type, foundation type, year of construction, detector type, geographical coordinates, altitude, temperature and lithology into the kernel estimation models. We developed predictive maps as well as a map of the local probability to exceed 300 Bq/m(3). Additionally, we developed a map of a confidence index in order to estimate the reliability of the probability map. RESULTS: Our models were able to explain 28% of the variations of IRC data. All variables added information to the model. The model estimation revealed a bandwidth for each variable, making it possible to characterize the influence of each variable on the IRC estimation. Furthermore, we assessed the mapping characteristics of kernel estimation overall as well as by municipality. Overall, our model reproduces spatial IRC patterns which were already obtained earlier. On the municipal level, we could show that our model accounts well for IRC trends within municipal boundaries. Finally, we found that different building characteristics result in different IRC maps. Maps corresponding to detached houses with concrete foundations indicate systematically smaller IRC than maps corresponding to farms with earth foundation. CONCLUSIONS: IRC mapping based on kernel estimation is a powerful tool to predict and analyze IRC on a large-scale as well as on a local level. This approach enables to develop tailor-made maps for different architectural elements and measurement conditions and to account at the same time for geological information and spatial relations between IRC measurements.

Une carte des zones de cisaillement ductiles des Alpes Centrales

The main deformation structures due to the Tertiary continental collision in the Western Swiss Alps are ductile shear zones. Four main shear zones can be recognized on the structural map, each characterised by a different shear direction. The first D I shear zone with a X I, SE (transverse) stretching direction has been created during the under-thrusting towards the SE of the European plate under the Adriatic plate. This took place mainly by ductile deformation of the upper part of the European continental basement with the formation of the external massifs basement folds and the Penninic foldnappes. The second D II shear zone (Simplon ductile shear zone) is characterized by a XII stretching, dipping from 0 to 30-degrees to the SW (longitudinal stretching). It is approximately 10 km wide, and crosses the Alpine nappes in an oblique direction. It corresponds to a relative SW transport direction of the upper units together with the Adriatic plate. This dextral transpression zone is also responsible for the stretching parallel to the elongation of the Alpine belt. The third D III shear zone is made of mylonites with a steep stretching direction and corresponds to the hanging wall of the Canavese reverse fault. The D IV shear zones, dextral wrench zones combined with underthrusting movement, are characterised by a W and SW stretching direction. They were formed during and after the S facing backfolding which for instance made the Mischabel fold and the Boggioleto fold. Actually it occupies two narrow areas of more ductile rocks between the Mischabel backfold to the N and the Monte Rosa nappe to the S and allong the Canavese Line. These dextral shear zones represent probably the western continuation of the Tonale Line dextral wrench fault. The D I to IV ductile shear zone were formed under greenschist and amphibolite facies conditions during the Tertiary orogenic metamorphism. Their regional distribution is limited to the metamorphic ductile zone representing the deep part of the Alpine belt, between 10 and 30 km depth. The emplacement and orientation of the shear zones was also directed by the geometry of the boundaries of the European and Adriatic plates. The analysis of the superposed Central Alpine shear zones permits thus to propose a model of the history of the relative convergent and wrench movements which took place between the European and Adriatic plates during the Alpine Tertiary continental collision.

The Role of Magnesium in Concrete Deterioration, HR-355, Appendix, 1994

In the main report concerning the role that magnesium may have in highway concrete aggregate, over 20,000 electron microprobe data were obtained, primarily from automated scans, or traverses, across dolomite aggregate grains and the adjacent cement paste. Representative traverses were shown in figures and averages of the data were presented in Table II. In this Appendix, detailed representative and selected analyses of carbonate aggregate only are presented. These analyses were not presented in the main report because they would be interesting to only a few specialists in dolomite· rocks. In this Appendix, individual point analyses of mineral compositions in the paste have been omitted along with dolomite compositions at grain boundaries and cracks. Clay minerals and quartz inclusions in the aggregate are also not included. In the analyses, the first three column headings from left to right show line number, x-axis, and y-axis (Line number is an artifact of the computer print-out for each new traverse. Consecutive line numbers indicate a continuous traverse with distances between each point of 1.5 to a few μ-m. X-axis and y-axis are coordinates on the electron microscope stage). The next columns present weight percent oxide content of FeO, K20, CaO, Si02, Al203, MgO, SrO, BaO, MnO, Na20, and C02 (calculated assuming the number of moles of C02 is equal to the sum of moles of oxides, chiefly CaO and MgO), TOTAL (the sum of all oxides), and total (sum of all oxides excluding COi). In many of the analyses total is omitted.

Progress in front propagation research

We review the progress in the field of front propagation in recent years. We survey many physical, biophysical and cross-disciplinary applications, including reduced-variable models of combustion flames, Reid's paradox of rapid forest range expansions, the European colonization of North America during the 19th century, the Neolithic transition in Europe from 13 000 to 5000 years ago, the description of subsistence boundaries, the formation of cultural boundaries, the spread of genetic mutations, theory and experiments on virus infections, models of cancer tumors, etc. Recent theoretical advances are unified in a single framework, encompassing very diverse systems such as those with biased random walks, distributed delays, sequential reaction and dispersion, cohabitation models, age structure and systems with several interacting species. Directions for future progress are outlined
