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
Child Abuse and Eating Disorders: a systematic review and meta-analysis. PROSPERO International prospective register of systematic reviews.
No full textIn recent years there has been a resurgence of interest in the contribution of abuse to the development of subsequent psychopathology (de Groot, 1999; Smolak, 2002). Although the literature tends to focus on one specific form of abuse, typically sexual, more than one type can be found within families: physical and emotional abuse are in fact also common; they tend to interact and exacerbate each other. Research on the relationship between childhood abuse and EDs has been contradictory and inconclusive and seems to suggest that, if there is a relationship between abuse and eating disorders, it is causally complex. This study had the goal to examine the magnitude and consistency of the association among different types of child abuse – sexual (CSA), physical (CPA), emotional (CEA) - and eating disorders (EDs) in the literature to date. Meta-analysis was used to examine the question. Electronic databases through January 2014 were searched. Studies reporting rates of sexual, physical, emotional abuse, in people with anorexia nervosa, bulimia nervosa and BED were retrieved. Child Sexual, Physical or Emotional abuse rates as well as demographic, clinical, and methodological variables were extracted from each publication independently by two authors. Data were pooled according to random effect model.
50 of 1714 studies assessed for eligibility met the inclusion criteria, comprising a total of individuals with Anorexia Nervosa, Bulimia Nervosa, and Binge Eating Disorders and documenting different type of abuse. The pooled association effect for a form of abuse in people with ED were statistically significant (p< 0.05).
Altough many theoretical perspectives have tried to explain the link between abuse and EDs, the controversy in the literature regarding the associations between abuse and EDs arises first from the methodological variability - diagnostic criteria for EDs, definitions of abuse, assessment techniques - and second from the limitations of the studies (Pope, 1992). Research will have to direct to more complex models that might expatiate these links in the context of complex interplay of other antecedent and moderating factors (Jenkins, 2013)
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
Social network confidants, duration of untreated psychosis and cannabis use in people with first episode psychosis: An exploratory study
No full textAim: Reduced social network (SN) might be associated with a longer duration of untreated psychosis (DUP) in people with first episode psychosis (FEP). We aimed at exploring the specific role of SN confidants on DUP, taking into account cannabis misuse, which is known to influence DUP and might be associated with social functioning. Methods: People with FEP recently referred to an inner London Early Intervention Service were assessed with standardized instruments exploring SN characteristics, DUP and cannabis misuse. Results: Taking into account cannabis misuse, we found an association between confidants and DUP (P = 0.020), with the higher the number of confidants, the shorter the DUP. Conclusions: Confidants may provide access to, and perceptions of, social support and this may increase early engagement for people with FEP, reducing DUP and possibly improving outcomes. Future research should identify correlates of small networks of confidants, which could inform early detection community initiatives
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
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
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
