Inherited structures and slope evolution: the case of the left slope of the Ridnaun Valley.
No full textThe left slope of the Ridnaun Valley (Sterzing/Vipiteno, South Tyrol, Italy), set on the crystalline units of the
Austoalpine Nappe of the alpine orogenic wedge, shows evidence of quaternary gravitational evolution which
highly depends on the interaction between the slope trend and the brittle/ductile structural setting. The slope is
carved within the paragneisses rocks of the Oetztal - Stubai Unit and the micaschists of the Schneeberg Unit.
These two units are separated by a NNW gentle dipping tectonic contact (mylonites and cataclasites), which
obliquely intersects the E–W slope, and is well described by ultracataclasitic layers following the regional low
angle north-dipping schistosity. Folds with sub-horizontal E–trending axes induce the change in the dip direction
of the regional schistosity from N dipping to SE dipping. NNE–SSW and N–S trending faults, having a mean 1m
thick incoherent fault breccia, affect the entire slope. These, as well as the folds and the ultracataclastic layers, has
significant consequences on rock mass mechanical properties and on mechanisms and timing of the gravitational
phenomena that developed along the slope.
The results obtained by field work and the analysis of the LiDAR-derived digital elevation model clearly revealed
different gravitational movements. A fully evolved gravitational collapse, having the typical features of a Rock
Avalanche (RA), characterizes the central part of the slope; whereas to the east and west of the RA, deep seated
gravitational slope deformations still involve the slope. The RA, whose deposit covers an area of about 2.4 km2,
had obstructed the valley, resulting in a rock avalanche – dammed lake. This has been breached and run out
at an interval of time not yet defined. An ongoing gravitational deformation involves the uphill sections of the
slope, next to the crown area. In addition, to the west and east of the RA, morphostructural features as double
ridge, scarps – counterscarps, trenches are evident. PS and DS - SAR (Synthetic Aperture Radar) interferometry
data (derived ERS, ENVISAT and RADARSAT scenes), generated by the Tele-Rilevamento-Europa (TRE) and
provided to the EURAC-Institute for Applied Remote Sensing for the EU-FP7 Project ’SAFER’, with the purpose
of an integration of the Inventory of Landslide Phenomena in Italy (IFFI Project), testify an ongoing movement on
both the DSGSDs bordering the RA, highlighting a most unstable area at the western sector.
The heterogeneous behavior of the slope is most likely controlled by the interaction between the ductile and brittle
structures: on one hand the folds coupled with the non–parallelism between the tectonic contact trend and the
slope, ease the DSGSD formation and evolution and act as releasing factor for the RA crown area. On the other
hand, the recognized fault network act as the lateral release of the unstable areas, and play a major role as a predisposing
factor for gravitational failures because of the increasing degree of damage approaching each principal fault

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
