Seismotectonic analysis around the Mont Terri rock laboratory (Switzerland): a pilot study

For this pilot study we used recorded seismic events from the SED permanent network and data from a dedicated SNS network to improve the seismotectonic understanding of very weak seismicity in the vicinity of the Mont Terri underground laboratory. We combined field data on faults with microseismic events and modelling of stress and focal mechanisms. Eighty-six events with very low magnitudes (ML ≈ −2.0 to 2.0) recorded between July 2014 and August 2015 were located within a radius of 10 km of the underground laboratory and used for modelling. We compiled 234 fault/striation data from laboratory tunnels and regional geology, and also from seismic/borehole data on basement faults. With this database we defined seven groups of main faults in the cover and four groups in the basement. For each of these groups we computed a synthetic focal mechanism that was subsequently used to determine a synthetic P-phase waveform. The synthetic waveforms were then correlated with the microseismic events of the cover and the basement respectively. Of these, 78 events yielded satisfactorily correlation coefficients that we used for a regional seismotectonic interpretation. The synthetic focal mechanism can be linked to the main regional structural features: the NNE–SSW-oriented reactivated faults associated with the Rhine Graben development, and the NE–SW-oriented reverse faults related to the thrust development of major folds such as the Mont Terri anticline. The results for this pilot study confirm that our affirmative method can be used to augment local and regional seismotectonic interpretations with very weak-intensity earthquake data

Sports tribes and academic identity: teaching the sociology of sport in a changing disciplinary landscape

Using data from 15 semi-structured interviews with UK-based early/mid-career academics, this paper offers an empirically informed assessment of how lecturers teaching/researching the sociology of sport are managing their careers in a changing higher education landscape. Those interviewed were involved in the delivery of sociological content to a range of sports-themed courses with the interviews focusing on the changing fashions in studying sport (including a rapid increase in enrolment on certain sports-themed courses), and on the nature of the relationships with colleagues working in the same area (i.e. sport), but who teach/research it from a different discipline. The paper draws upon the processes of individualisation which lay at the root of reflexive modernisation to better understand the lived experiences of those interviewed. Using the metaphors of tribes, doors and boundaries, I assess the extent to which those interviewed felt there were opportunities for an interdisciplinary pedagogic approach to ‘sport’. The paper explores the relationship between the sociology of sport and its parent discipline (i.e. sociology) and where it might feature in a future (post-disciplinary?) landscape

INTERACTIONAL PATTERNS OF ELDERLY INDIVIDUALS: IMPLICATIONS FOR SUCCESSFUL ADAPTATION TO AGING

This investigation explores the interactive behavior of individuals over the age of sixty-five as it relates to life satisfaction. Three communicative elements which covary with life satisfaction are examined: (1) The frequency with which elderly individuals enter into interaction; (2) the closeness felt by the elderly toward those interactants; and (3) the content of the interaction. Several communicator characteristics, the individual\u27s age, sex, living environment, and interactive partner, mediate the relationship between interaction and life satisfaction. Elderly individuals living in three separate living environments participated in this study. In all, one-hundred and twenty individuals over sixty-five years of age completed the Adult Communication Survey. This survey documented their communication behavior and measured their level of life-satisfaction. Three research questions were tested within this investigation. Results from the research questions support the contention that the interactive behavior of elderly individuals covaries with levels of life satisfaction. This relationship is complex, mediated by such factors as living environment and the parnter of the interaction. The relationship between interaction and life satisfaction is differentially explained by three prevelant aging theories. These theories are presented to introduce potential connections to the three communication variables. Overall, results from this study indicate the importance of interactive behavior in the elderly population. Implications of these results are discussed

Using gaze information to improve image difference metrics

This is the copy of journal's version originally published in Proc. SPIE 6806. Reprinted with permission of SPIE: http://spie.org/x10.xml?WT.svl=tn7We have used image difference metrics to measure the quality of a set of images to know how well they predict perceived image difference. We carried out a psychophysical experiment with 25 observers along with a recording of the observers gaze position. The image difference metrics used were CIELAB _DEab, S-CIELAB, the hue angle algorithm, iCAM and. A frequency map from the eye tracker data was applied as a weighting to the image difference metrics. The results indicate an improvement in correlation between the predicted image difference and the perceived image difference

Regression based characterization of color measurement instruments in printing applications

This is the copy of journal's version originally published in Proc. SPIE 7866: http://spie.org/x10.xml?WT.svl=tn7. Reprinted with permission of SPIE.In the context of print quality and process control colorimetric parameters and tolerance values are clearly defined. Calibration procedures are well defined for color measurement instruments in printing workflows. Still, using more than one color measurement instrument measuring the same color wedge can produce clearly different results due to random and systematic errors of the instruments. In certain situations where one instrument gives values which are just inside the given tolerances and another measurement instrument produces values which exceed the predefined tolerance parameters, the question arises whether the print or proof is approved or not accepted with regards to the standard parameters. The aim of this paper was to determine an appropriate model to characterize color measurement instruments for printing applications in order to improve the colorimetric performance and hence the inter-instrument agreement. The method proposed is derived from color image acquisition device characterization methods which have been applied by performing polynomial regression with a least square technique. Six commercial color measurement instruments were used for measuring color patches of a control color wedge on three different types of paper substrates. The characterization functions were derived using least square polynomial regression, based on the training set of 14 BCRA tiles colorimetric reference values and the corresponding colorimetric measurements obtained by the measurement instruments. The derived functions were then used to correct the colorimetric values of test sets of 46 measurements of the color control wedge patches. The corrected measurement results obtained from the applied regression model was then used as the starting point with which the corrected measurements from other instruments were compared to find the most appropriate polynomial, which results in the least color difference. The obtained results demonstrate that the proposed regression method works remarkably well with a range of different color measurement instruments used on three types of substrates. Finally, by extending the training set from 14 samples to 38 samples the obtained results clearly indicate that the model is robust
