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
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
Simulation: a learning pedagogy for nursing
Full text linkSimulation features strongly within the undergraduate nursing curriculum for many Universities. It provides a variety of opportunities for students as they learn and develop their clinical nursing skills (Berragan, 2011). The nurse education literature supports the use of simulation for helping students to feel more confident in performing clinical work (Leigh, 2008). However, self-confidence and self-efficacy are only part of the learning picture. Other important aspects of learning nursing include conceptual knowledge and skill development. This poster presentation considers the theoretical positioning and understanding of simulation as a learning approach for undergraduate nursing skills development. It offers an analysis of nursing simulation literature in relation to learning. My focus is to determine how learning is described and explored within the literature on simulation. My interest is also in the use of learning theory in the design and implementation of simulation for nursing students. This presentation is based on the work from part of the literature review for my current doctoral study with the University of the West of England. It has been inspired by my involvement with the facilitation and assessment of simulation within the faculty. My doctoral research explores the impact of simulation on learning for undergraduate adult nursing students. Literature reviews by Kaakinen and Arwood (2009) and Cant and Cooper (2010) and my own literature searches demonstrate that, although nascent, there is a developing body of literature, which has as its focus learning and simulation. This literature was examined in order to determine how learning was defined and understood within the field of simulation for nurse education. The learning theories and approaches explored include behaviourism, social learning theory, constructivism, adult learning theory, experiential learning, situated learning, activity theory and reflective practice. My analysis of the literature has shown that simulation offers very different ways of conceptualizing learning. A more explicit examination of theories of learning may therefore be useful in informing future practice and future research on simulation. This work highlights possibilities and raises questions in relation to learning through simulation, encouraging engagement with the conceptualization of learning through simulation. It is hoped that this will act as a catalyst to stimulate further debate in consideration of simulation as a learning pedagogy
Consultancy in nursing: Roles and opportunities
No full textThis paper considers the development of consultancy roles within nursing, specifically examining internal and external approaches to consultation. As consultancy in nursing develops there appear to be two major trends: external or independent consultancy where the incumbents focus purely upon this role as their 'job', and internal consultation where consultancy is seen as an integral part of their role and is a subrole of the advanced practitioner. In promoting consultancy as a means of developing and enhancing advanced practice, suggestions are made for future opportunities for consultancy in nursing and its role in the development of nursing practice
