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
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
Antisense RNA Design, Delivery, and Analysis
Full text linkThis open access volume gathers a variety of models, delivery systems, and approaches that can be used to assess RNA technology for exploiting antisense as a therapeutic intervention. Beginning with a section on the design of antisense technology and their delivery, the book continues by covering model systems developed to evaluate efficacy, both in vivo and in vitro, as well as methods to evaluate preclinically the toxicity associated with these new potential drugs, and intellectual property considerations. Written for the highly successful Methods in Molecular Biology series, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Authoritative and practical, Antisense RNA Design, Delivery, and Analysis provides basic knowledge and a large collection of methods to facilitate the work of newcomers to this vibrant and expanding field. This book was conceived thanks to the network DARTER (Delivery of Antisense RNA Therapeutics). DARTER is funded by the EU Cooperation of Science and Technology (COST), which aims to enhance interaction and collaborations between researchers in Europe and other countries

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

Molecular Therapies for Inherited Retinal Diseases
Full text linkFollowing the implementation of next-generation sequencing technologies (e.g., exome and genome sequencing) in molecular diagnostics, the majority of genetic defects underlying inherited retinal disease (IRD) can readily be identified. In parallel, opportunities to counteract the molecular consequences of these defects are rapidly emerging, providing hope for personalized medicine. ‘Classical’ gene augmentation therapy has been under study for several genetic subtypes of IRD and can be considered a safe and sometimes effective therapeutic strategy. The recent market approval of the first retinal gene augmentation therapy product (LuxturnaTM, for individuals with bi-allelic RPE65 mutations) by the FDA has not only demonstrated the potential of this specific approach, but also opened avenues for the development of other strategies. However, every gene—or even every mutation—may need a tailor-made therapeutic approach, in order to obtain the most efficacious strategy with minimal risks associated. In addition to gene augmentation therapy, other subtypes of molecular therapy are currently being designed and/or implemented, including splice modulation, DNA or RNA editing, optogenetics and pharmacological modulation. In addition, the development of proper delivery vectors has gained strong attention, and should not be overlooked when designing and testing a novel therapeutic approach. In this Special Issue, we aim to describe the current state of the art of molecular therapeutics for IRD, and discuss existing and novel therapeutic strategies, from idea to implementation, and from bench to bedside
