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
PredictiveEcology/SpaDES.core: v1.0.8
No full textKnown issues: https://github.com/PredictiveEcology/SpaDES.core/issues
version 1.0.8
new features
Plots function can be used like Plot, but with types specified.
The devices to save on disk will have some different behaviours to the screen representation, since "wiping" an individual plot on a device doesn't exist for a file device.
version 1.0.7
new features
Plots function that will produce zero to 4 types of items that are relevant for plotting: 1) Visual on screen, 2) The plot object saved to disk, 3) The raw data that went into the plot and 4) The plot as one or more image files, e.g., .png or .pdf via ggsave
spades now accepts an events argument, which will limit the events that are run to those specified in the argument. This seems to be most useful for the init case, e.g., spades(sim, events = "init"). See ?spades.
messaging during simInit now is prefixed with Sys.time() and "simInit"
messaging during spades is simplified to take up fewer characters: INFO:: has been removed
simInit now checks for minimum version of SpaDES.core needed in a module and stops if it fails, giving instructions how to upgrade.
several human-readable only elements of a module metadata are no longer enforced, including spatialExtent, as they are not used by the spades algorithms
new function: anyPlotting to test whether plotting of one form or another should occur
line-by-line messaging during spades call is now more informative, including module name (by default shortened -- can be changed with options("spades.messagingNumCharsModule")))
defineParameter can now accept a vector of "class", so a parameter can be more than one class.
Presumably this should generally not be used, but a good reason could be, say, c("numeric", "function"), where the use can pass either a numeric or a function that would calculate that numeric.
new helper function simFile to generate file names for use with e.g., saveSimList
zipSimList is now exported
spades will now attempt to load reqdPkgs, which is already done in simInit.
In cases where simInit was not run, e.g., Cache(simInitAndSpades, ..., events = "init"), then modules will not have access to packages.
For cases where simInit was called, then this should add very little overhead.
saveSimList will now convert file-backed Raster* class objects to memory if fileBackend = 0.
Previously, it left them as is (on disk if on disk, in memory if in memory).
For code/documentation contributors, markdown syntax is now turned on and can be used when writing function documentation
The first event will now run if it is scheduled to be prior to time(sim) in the case where it is equal to or after end(sim). Previously, this would not run any events if time(sim) >= end(sim) && events(sim)[[1]] < time(sim).
minor documentation modifications
Add optional .seed parameter for modules (#163)
Bugfixes
defineParameter was throwing is.na(default) warning when a parameter was not an atomic.
recovery mode did not work correctly if the file-backed rasters were in the temporary directory, as it would collide with the temporary directory of the recovery mode mechanism. Now recovery mode uses a dedicated temporary directory
