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
Mechanical properties of rock units from the Pompeii archaeological site
No full textThe definition of compatible conservation interventions on the archaeological built asset requires a comprehensive knowledge of physical, chemical and mechanical properties of the ancient masonry structures and their components. However, information on the mechanical properties of units, mortars and masonry assemblages are still lacking especially with reference to one of the most popular UNESCO World Heritage Sites in Italy, the Pompeii archaeological site. Thus, the paper focuses on the mechanical characterization of original rock specimens collected within the new archaeological excavation work area in Regio V of the Pompeii site. Ultrasonic pulse velocity tests (UPV) and Schmidt hammer rebound test were carried out on ten units of three different rock types: three travertine, five lava and two foam lava (i.e. “calcare del Sarno”, “lava” and “cruma”). Then, UPV were carried out on 51 cubic specimens obtained from the cut of the units, both at ordinary moisture content and after drying. Finally, uniaxial compression tests were carried out on 32 cubic specimens. In the following, the results of non-destructive tests are discussed and compared with those provided by destructive tests in terms of compressive strength
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
SEISMIC BEHAVIOR OF ARCHAEOLOGICAL MULTIDRUM COLUMNS AT THE POMPEII SITE
No full textFree-standing multidrum stone columns are widespread elements in archaeological areas. The
present study aims at investigating the behavior of these elements under seismic excitations. The
dynamic behavior of free-standing multidrum columns is greatly affected by geometrical properties,
constitutive materials, state of preservation, and amplitude and frequency of the seismic action. The
first step of the research involved a wide and detailed survey for the definition of the mean
geometrical properties affecting the seismic behavior of these columns in the archeological Pompei
site. To this end, a wide range of grey-tuff columns (103 elements) from four different areas of the
site involving private and public areas, were investigated. Then, numerical analyses were carried out
based on the Finite Element Method (FEM) to investigate the seismic behavior of such elements. A
column from the tetrastyle atrium of Casa del Fauno was selected for the analysis. The house is one
of the largest and most visited private buildings at the Pompeii archeological site. The selected
column presented deep degradation and needed specific and urgent attention for its assessment. In
the following, the detailed survey and the modeling phases of the investigated element are described
and the outcomes of the numerical analysis are reported and discussed
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
