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
Competing narrations around visual representations of environmental conflicts and protests
No full textAgainst the backdrop of green cultural criminology and drawing on a radical interactionist perspective, in this contribution we suggest the importance of considering the ephemeral, ambiguous, and ever-changing borders of meanings around images shared online, especially in the context of socio-environmental conflicts. In particular, we address the multiple and competing discourses that emerge from a video shared online depicting a conflict between an activist and a police officer, as reflected in the comments and interpretations by environmental activists in an online community. We conclude by suggesting that a green cultural criminology informed by radical interactionism can lead to a more comprehensive understanding of the complexity of socio-environmental conflicts and protests
Il “dominio” penale come cosmogonia. Critica della violenza e “bisogno interiore del diritto”
No full textIn modern and especially late-modern society occurrence and prevalence of violent behaviours are related to an increased "need" of legal regulations, and vice versa, it is such need to foster violent behaviours.according to the circular mechanisms which are paramount in explaining social phenomena. To this relationship the mass media contribute massively, also through the legal formats they attribute to their story telling of violence.The area of violence and overbearing need of law may be reduced fundamentally enlarging, through opportunities of communicative and narrative interactions among individuals and communities,the mutual truth
Conveying environmental harms through music: some directions for green cultural criminology
No full textThis chapter contributes to the perspective of green-cultural criminology, which was pioneered by Nigel South and Avi Brisman with an agenda-setting article and a book published ten years ago (Brisman and South, 2013, 2014). Drawing on our previous work in Italy on the criminalised NoTap eco-justice movement and the environmental disaster of Casale Monferrato, we aimed to show how green-cultural criminology can extend its study of representations of environmental harms to music, as the latter can be an important conveyor of harms and resistance while also being a powerful healing tool. We conclude our tribute to a great scholar, friend and music lover with a coda-conclusion where we reinforce the need to study music within green-cultural criminology, also identifying directions for future research in this area
How a local active force modifies the structural properties of polymers
Full text linkWe study the dynamics of a polymer, described as a variant of a Rouse chain, driven by an active terminal monomer (head). The local active force induces a transition from a globule-like to an elongated
state, as revealed by the study of the end-to-end distance, the variance of which is analytically predicted under suitable approximations. The change in the relaxation times of the Rouse-modes produced by the local self-propulsion is consistent with the transition from globule to elongated conformations. Moreover, also the bond–bond spatial correlation for the chain head are affected by the self-propulsion and a gradient of over-stretched bonds along the chain is observed. We compare our numerical results both with the phenomenological stiff-polymer theory and several analytical predictions in the Rousechain approximation
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
