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
Food abuse : Mealtimes, helplines and 'troubled' eating
No full textFeeding children can be one of the most challenging and frustrating aspects of raising a family. This is often exacerbated by conflicting guidelines over what the ‘correct’ amount of food and ‘proper’ eating actually entails. The issue becomes muddier still when parents are accused of mistreating their children by not feeding them properly, or when eating becomes troubled in some way. Yet how are parents to ‘know’ how much food is enough and when their child is ‘full’? How is food negotiated on a daily level? In this chapter, we show how discursive psychology can provide a way of understanding these issues that goes beyond guidelines and measurements. It enables us to examine the practices within which food is negotiated and used to hold others accountable. Like the other chapters in this section of the book, eating practices can also be situations in which an asymmetry of competence is produced; where one party is treated as being a less-than-valid person (in the case of family practices, this is often the child). As we shall see later, the asymmetry can also be reversed, where one person (adult or child) can claim to have greater ‘access’ to concepts such as ‘appetite’ and ‘hunger’. Not only does this help us to understand the complexity of eating practices; it also highlights features of the parent/child relationshipi and the institutionality of families
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
Construction and action in food evaluation : conversational data
No full textThis study engages both social psychological research on 'attitudes' and discursive work on 'evaluative practices.' Methodological constraints in both of these fields have resulted in a relative lack of attention to everyday interaction. By using conversational data, the current study extends discursive research and highlights the constructive and constructed nature of food evaluations. Family mealtimes were audiotaped, transcribed, and analyzed using discursive and conversational analytic procedures. Direct evaluative expressions such as 'like' and 'nice' were examined in terms of their construction and placement in the talk. The rhetorical organization of these expressions highlighted the extent to which food evaluations are oriented to actions such as accounts, compliments, and offers of food. Examples of these activities are discussed in relation to the interactional construction of evaluations. Implications of the study for the fields of food preferences and health promotion are also addressed
Adult and child use of love, like, don't like and hate during family mealtimes : subjective category assessments as food preference talk
No full textFood preference is now a ubiquitous concept in eating research, and closely associated with actual consumption, particularly in relation to children's food preferences. Research in this area is beginning to reveal the effects of parent–child interaction on eating practices though relatively little attention has been paid to the discursive and lexical processes involved. Food preferences are typically associated with the terms ‘likes’ and ‘dislikes’ in food preference research. By contrast, adults and children typically use the terms ‘love’, ‘like’, ‘don’t like’ and ‘hate’ to construct and manage food preferences in everyday meal conversations. A corpus of 270 video- and audio-recorded English and Scottish family mealtimes, involving children aged 1–17 years, was searched and analysed for any and all occurrences of subjective category assessments (SCAs; e.g., ‘I like X’), featuring the terms ‘love’, ‘like’, ‘don’t like’ and ‘hate’. Discursive psychology was used to analyse the transcripts and recordings, and illustrated the disparity between adult and child use of SCAs and food preference talk. Within the data set, parents typically made claims about what their children like, and in doing so claimed epistemic primacy over their children's food preferences. Children, by contrast, typically made claims about their own ‘don’t likes’ and likes, and these were frequently countered by their parents or treated as inappropriate claims. Implications for how parents and researchers might reorient to the food preferences lexicon are discussed
