Spatial and temporal variations in growth rates along active normal fault Systems: an example from the Lazio-Abruzzo Apennines, central Italy
No full textThe geometry, kinematics and rates of active extension in Lazio–Abruzzo, Italian Apennines, have been measured in order to gain a better
understanding of the spatial and temporal variations in fault growth rates and seismic hazards associated with active normal fault systems.
We present fault map traces, throws, throw-rates and slip-directions for 17 parallel, en e ́chelon or end-on active normal faults whose 20–
40 km lengths combine to form a soft-linked fault array ca. 155 km in length and ca. 55 km across strike. Throw-rates derived from
observations of faulted late-glacial features and Holocene soils show that both maximum throw-rates and throw-rate gradients are greater on
centrally-located faults along the strike of the array; total throws and throw gradients show similar spatial variations but with weaker
relationships with distance along strike. When summed across strike, throw-rates are increasingly high towards the centre of the array relative
to summed throws. We interpret the above to suggest that throw-rates have changed in the recent past (ca. 0.7 Ma) from spatially-random
fault growth rates (initiating at 2.5–3.3 Ma) to growth rates that are greater on centrally-located faults. We interpret this as evidence for fault
interaction producing throw-rate variations that drive throw profile readjustment on these crustal scale soft-linked faults. The results are used
to discuss seismic hazards in the region, which are quantified in a second paper in this issue
Fault scaling relationships, deformation rates and seismic hazards: an example from the Lazio-Abruzzo Apennines, central Italy
No full textSpatial variations in the number of seismic shaking events in a given time period (frequency) implied by measured throw-rates associated
with active normal faults in central Italy are investigated through comparison with models of fault growth and the historical record of
earthquake shaking for the region. Measured offsets of 18 ka glacial features provide a throw-rate database averaged over a time period much
longer than the reliable portion of the historical earthquake record for the region (,ca. 1 ka). Throw-rates are greatest in the centre of the
studied fault array and show a six-fold decrease from central to distal faults, implying spatial variations in the frequency of seismic shaking
events. We attempt to validate these observations by comparing them with throw-rates predicted by a calculation that takes into account the
growth patterns of normal fault systems that exhibit well-known scaling relationships between fault length and throw. We also convert the
measured throw-rates into a map of implied frequency of seismic shaking events and attempt to validate the map by comparing it with
the probably complete records of seismic shaking since 1349 A.D. that exist for 14 towns in the region. Our results confirm that the throwrate
database is compatible with both the record of historical seismic shaking and what we know about the growth of normal faults. The
results imply that knowledge of fault scaling parameters and geological determined deformation rates are valuable tools in seismic hazard
assessment
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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
Full text linkWe 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
