Le temps-discours, les temps-images. Pluralisation et ouverture de l'organisation temporelle de la vie quotidienne
No full text«The Time-Discourse, the Time-Images. Pluralization and Opening of the Temporal Organization of the Everyday Life».
Heidrun Friese [39-64].
The question of time takes up a main place in the social theory. The author examines particularly the place of the construction of time in the theories of action in the work of Bourdieu and Giddens. Pointing out their deficiencies, the author describes the multiplicity of strategies in the construction of a splited temporality in the ordinary person everyday acts (the article relies on an ethnographie survey in Sicily). She pleads for the integration in a renewed sociology of time of this irreducible plurality of time (biographical time, historical local time, historical universal time), which characterizes all the local practices.«Le temps-discours, les temps-images.

La question du temps occupe une place centrale dans la théorie sociale. L'auteur examine en particulier la place de la construction du temps dans les théories de l'action de Bourdieu et de Giddens. Pointant leurs insuffisances, l'auteur - en s'appuyant sur une enquête ethnographique menée en Sicile (dont elle a par ailleurs tiré un ouvrage) - décrit les multiples stratégies de construction d'une temporalité éclatée à l'œuvre dans l'agir quotidien des personnes et plaide pour l'intégration de cette pluralité irréductible (temps biographique, temps historique local, temps historique universel), qui caractérise toute pratique locale, dans une théorie sociologique du temps renouvelée.Friese Heidrun.

Risky locations: refugee settlement patterns and conflict
No full textAlthough constructed for safety, many refugee settlements today encounter violence, becoming risky locations for refugees and hosts. This dissertation investigates why some of these refugee settlements experience violence and not others. Heidrun Bohnet argues that the geographical location and distribution of refugees are influential factors in determining refugee-related conflict. While previous research has highlighted that refugees can become involved in new conflict situations in the host country, little comparative analysis exists that investigates the link between refugees and conflict. By using new quantitative refugee data on Africa from 1999-2010, this dissertation shows that the geographical space occupied by refugees is closely related to the risk of conflict. The author contends that a disaggregated approach towards refugees needs to be taken to understand refugee-related conflict within refugee settlements and beyond them
Unmyelinated tactile afferents have opposite effects on insular and somatosensory cortical processing
No full textA previous functional magnetic resonance imaging (fMRI) study of an A-beta deafferented subject (GL) showed that stimulation of tactile C afferents (CT) activates insular cortex whereas no activation was seen in somatosensory cortices. Psychophysical studies suggested that CT afferents contribute to affective but not to discriminative aspects of tactile stimulation. We have now examined cortical processing following CT stimulation in a second similarly deafferented subject (IW), as well as revisited the data from GL. The results in IW showed similar activation of posterior insular cortex following CT stimulation as in GL and so strengthen the view that CT afferents underpin emotional aspects of touch. In addition, CT stimulation evoked significant fMRI deactivation in somatosensory cortex in both subjects supporting the notion that CT is not a system for discriminative touch
Multiscale Modeling of the Åre 6.2 Thief Zones in the Heidrun Field: Its Potential for Fluid Flow Predictions
No full textThe upper reservoir intervals of the Lower Jurassic Åre Formation in the Heidrun Field (Offshore mid-Norway) are very heterolithic and have the lowest oil recovery factor of the field despite significant amounts of remaining reserves. One of these reservoir zones is the formation Åre 6.2, which is mainly composed of tide-dominated heterolithic channel belt deposits. It contains particular layers that have excellent properties with permeabilities up to 10 Darcy. These layers are predicted to affect the production results as they can act as ‘thief zones’ within the low permeable heterolithic facies causing large quantities of water to flow through, leading to poor sweep efficiency and early water breakthrough. This study focuses on constructing conceptual depositional models of the Åre 6.2 and building detailed geological models to investigate the effect of the thief zones on overall fluid flow predictions.Conceptual depositional models were constructed by determining the characteristics of the reservoir and its depositional environment. Seven cored wells were used as the primary data to interpret lithofacies and facies associations. The study showed that Åre 6.2 mainly consisted of structured sandstones and heterolithic lithofacies with features that indicate that tidal process play an important role in the deposition. The influence of tidal process on deposition is further exemplified by the identification of two different types of channel facies associations, which are tidal and distributary channels. The thief zones were found in both facies associations, suggesting that the thief zones were formed during high freshwater discharge into the channels supplying coarse sandy material influx during a phase of high-energy deposition. To make detailed models of the tidal and distributary channels, multiscale modeling techniques were utilized to better represent the reservoir heterogeneities at the lithofacies and facies association scales.At the lithofacies scale, models were built in SBEDTM and the upscaled values of each lithofacies were obtained by applying the Representative Element Volume (REV) concept. The upscaled values were then used as input in the facies association scale models in order to represent the heterogeneities at the lithofacies scale to the next heterogeneity level. This step is essential since heterogeneities at a smaller scale may affect reservoir flow properties. Two different channel models were built in ReservoirStudioTM based on the conceptual depositional model and using outcrop analogue data from the Gule Horn Formation (Neill Klinter Group) in the Albuen area (Greenland). Flow-based upscaling was used to analyze the model uncertainties and determine a proper upscaling grid size. Finally, streamline simulations were performed to identify the effect of the thief zones. The simulation confirms that the thief zones influence fluid flow in the reservoir zone significantly as most flow was concentrated in the thief zones.Petroleum Engineering and Geo-science
Functional role of unmyelinated tactile afferents in human hairy skin: sympathetic response and perceptual localization
No full textIn addition to A-beta fibres the human hairy skin has unmyelinated (C) fibres responsive to light touch. Previous functional magnetic resonance imaging (fMRI) studies in a subject with a neuronopathy who specifically lacks A-beta afferents indicated that tactile C afferents (CT) activate insular cortex, whereas no response was seen in somatosensory areas 1 and 2. Psychophysical tests suggested that CT afferents give rise to an inconsistent perception of weak and pleasant touch. By examining two neuronopathy subjects as well as control subjects we have now demonstrated that CT stimulation can elicit a sympathetic skin response. Further, the neuronopathy subjects' ability to localize stimuli which activate CT afferents was very poor but above chance level. The findings support the interpretation that the CT system is well suited to underpin affective rather than discriminative functions of tactile sensation

Biographical Storytelling in the Context of Counseling and Therapy
No full textA precondition for any hermeneutic analysis of biographies is that the interview partners generate life history narratives. The same applies to a counseling practice that is sensitized by biographical analysis. On the one hand, clients' narratives of their own experiences provide the counselor with information on their biographical self-constructions and the processes of the sedimentation of the experiences of their life history. On the other hand, such narratives are not only of diagnostic use for the counselor, but also contribute to the clients' self-understanding. The author works in a psychosocial counseling center for university students. The article describes the transfer and potential of a style of counseling which encourages and is sensitized by biographical narratives in the context of an institution with a specific task.

Nürnberger Glasschnitt im Detail. Neue Zuschreibungskriterien für den Nürnberger Glasschnitt im 17. und beginnenden 18. Jahrhundert und ihre Anwendbarkeit erörtert am Bestand des Germanischen Nationalmuseums
No full textThe author develops in this thesis new Criteria of Ascription for Nuremberg Wheel engraved Glasses of the 17th and 18 th Century.Nürnberg erlebte im 17. und 18. Jahrhundert eine Blütezeit der Technik des Glasschnitts: Die Oberflächen – meist die von Hohlgefäßen aus Glas – wurden mit feinen Darstellungen veredelt. Zu den häufigsten Motiven zählen Wappen, Patrizier- und Adelssitze und Szenen aus der Emblematik. Einige ihrer Werke signierten die Nürnberger Glasschneider mit einem Griffel mit Diamantspitze. Diesen wenigen signierten Gefäßen steht allerdings eine große Menge an unsignierten Arbeiten gegenüber. In der vorliegenden Forschungsarbeit werden durch systematische Untersuchung signierter Arbeiten von sechs Nürnberger Glasschneidern Zuschreibungskriterien entwickelt. Bei diesen handelt es sich vor allem um feine Details des Schnitts, wie z. B. die spezifische Laubgestaltung oder die Gestaltung der Körper miniaturhafter Staffagefiguren. Die Anwendbarkeit dieser Kriterien wird in einem zweiten Schritt erprobt: Dazu dienen die Gläser des Germanischen Nationalmuseums, deren Zuschreibung kritisch überprüft und entsprechend der Untersuchungsergebnisse angepasst werden. Wichtiges Werkzeug für die Untersuchungen sind Fotografien im Makrobereich, die im Abbildungsteil wiedergegeben sind
