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
Analysis of Experimental Wood Chipper Trauma on Bone
Get PDFIn the literature and research relating to human corpse dismemberment and mutilation, there are few studies focusing on wood chipper induced trauma. Most of what is known about wood chipper trauma is based on a handful of documented cases in which wood chippers were used for dismemberment. In pop culture media such as movies, television, and the internet, body disposal via wood chipper is portrayed as a quick and effective method of getting rid of a body and eliminating evidence while avoiding detection. This thesis addresses these shortcomings by providing thorough case reviews and a preliminary study on wood chipper induced trauma. Several case studies are analyzed in which wood chippers were used in criminal cases to dispose of bodies. From these we learn that when wood chippers are used to dispose of human remains and that small potentially difficult to recover bone fragments are produced. Furthermore, a laboratory experiment was designed to test the trauma produced when domestic pig (Sus scrofa) limbs were inserted into a home model wood chipper. Results show that bone fragment sizes range from 45 mm to less than 1 mm. Many of the larger fragments have one or two cuts with those cuts creating fragments with consistent diameters. This wood chipper also produced bone alterations including square, V-shaped, and W-shaped kerfs that were dissimilar to other types of sharp force trauma. Some of these defects may be class characteristics associated with this model of wood chipper while others may be individual characteristics due to wear-related defects of the specific wood chipper used. This thesis will assist the forensic community by providing information regarding trauma that can expected to be observed following dismemberment via wood chipper thereby facilitating event reconstruction, victim identification, and conviction of perpetrators
Combining a Line Search with an Alternate Light Source When Searching for Skeletal Remains
Get PDFSearches for human remains in outdoor wooded settings are typically done during the day to allow for the best possible light. As part of the process of decomposition, the skeletal system begins to become disarticulated; this natural process is sometimes altered by scavengers. In all cases, it is important to attempt collection of as many remains as possible. In the cases when remains may be fragmented and/or scavenged, it is important to ensure as many fragments are located and collected as possible. For these scenarios, it would be advantageous to make use of the fluorescent properties of bone. Once the crime scene recovery is complete, to include measurements and mapping of the incomplete skeletal fragments found during the daylight, searchers would find that returning to the scene at night and using an alternate light source (ALS) to locate any final remains is to their benefit. This research involves the comparison of day, night, and combination day/night searches. Upon completion of the data collection, it can be stated that any search involving the use of an ALS will outperform a search that does not use the ALS. When comparing the night search to the combination day/night search there are minimal differences, it is the comparison of the day search to the combination day/night search that shows significant differences in the number of remains collected. For bone fragments less than 1.5 inches, a greater proportion (p<0.001) of bones were located when combining a daytime line search with a nighttime ALS search when compared with a daytime line search alone
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
