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
The Interrelationship of Status and Health in the Tellico Reservoir: A Biocultural Analysis
Get PDFAnthropologists have been interested in the interaction of health and status in prehistoric populations for many years. Utilizing a biocultural perspective, this paper will investigate how social stratification affected health at sites from the Tellico Reservoir in eastern Tennessee. These sites, Citico (40MR7), Toqua (40MR6), and Tomotley (40MR5), were occupied in the late Mississippian period in Tennessee, during the Dallas phase (A.D. 1300-1600) (Schroedl, 1998). Skeletal indicators of stress were used to determine the health of the people interred at the three sites, and burial location was utilized to establish the status of these people.
Intra-site and inter-site analyses were conducted on the data collected from 649 skeletal remains from the three sites. The intra-site analysis compared the occurrence of stress markers between mound burials and village burials at Citico and at Toqua, while the inter-site analysis compared stress indicator incidence between the two mounds, among the three villages, and between combined mound data and combined village data. A comparison of stress marker occurrence was also performed between males and females to determine whether gender differences affected the amount of stress endured.
The determination of status was another area of focus for this paper. Analyses were conducted in order to ascertain whether classes of burial goods based on raw material were correlated in any manner with the stress indicators. Positive and negative correlations could then be used to establish the status of an individual. Correlation tests were also used to analyze the association between periostitis and anemia. The two are thought to have a synergistic relationship, in which the presence of one stress increases the susceptibility to the other stress.
The results of these various analyses indicate that there are differences in the incidence of stress markers based on status; individuals buried in mounds were less affected than individuals buried in villages. This outcome is probably due to differential distribution of food. Individuals in the Toqua mound were more stressed than those in the Citico mound, which may be the result of population size, and, therefore, food availability. Toqua village had the most stress of the three villages, which is possibly a function of political structure and food distribution. The results of the gender analysis suggest that both females and males were comparably stressed.
The correlation tests reveal that no significant relationship exists between stress markers and the classes of burial goods. As a result, the class of burial goods based on raw material cannot be used to determine the status of an individual. Finally, the correlation tests indicate that there is, indeed, a synergistic relationship between anemia and periostitis
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

Fetal paleopathology: an impossible discipline?
Get PDFThis chapter introduces the concept of fetal paleopathology in archaeological material, highlighting the limitations and potential of such research to inform us about the lives of mothers and their babies in the past. Problems with terminology, aging methods, preservation and recognizing lesions in skeletal remains are discussed, before potential new sources of research are highlighted
