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
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
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

Get PDFDie Narzisstische Persönlichkeitsstörung (NPS) wird aufgrund der inkonsistenten Konzeptualisierung stark diskutiert. Ziel der Studie war es, NPS-Patienten zu untersuchen, um mit empirischen Daten die Validität und klinische Relevanz der NPS zu diskutieren. Es wurden zwei epidemiologische Studien durchgeführt. Studie 1 betrachtet die allgemeine psychische Belastung und Komorbidiätsraten, Studie 5 schaut auf die Stabilität und Remissionsrate der Diagnose und der diagnostischen Kriterien. Studie 1 fand eine erhöhte allgemeine psychische Belastung und hohe Komorbiditätsraten für affektive Störungen und Störungen durch Substanzkonsum, Studie 5 fand eine moderate Remissionsrate von 53%. In Studie 2 und 3 wurden selbstbezogene Kognitionen und Emotionen untersucht. Studie 2 erforschte die explizite und implizite Selbstwertschätzung. Es zeigte sich, dass die NPS mit einem niedrigen expliziten aber einem unbeeinträchtigten impliziten Selbstwert einhergeht. Studie 3 betrachtete Schamneigung bei der NPS. NPS-Patienten zeigten eine höhere explizite und implizite Schamneigung. Das indiziert, dass die narzisstische Vulnerabilität (niedriger expliziter Selbstwert, hohe explizite und implizite Schamneigung) bei NPS-Patienten eine Rolle spielt. In Studie 4 wurde die kognitive und emotionale Empathie untersucht. NPS-Patienten zeigten eine niedrigere emotionale Empathie aber eine unbeeinträchtigte kognitive Empathie. Die Ergebnisse passen zur aktuellen Kritik, dass die diagnostischen Kriterien zu eng sind, um die NPS adäquat zu beschreiben. Studien 1–3 geben Hinweise für die narzisstische Vulnerabilität, die nicht in den diagnostischen Kriterien repräsentiert wird, Studie 4 bringt Hinweise für eine ungestörte kognitive Empathie, was konträr zum diagnostischen Kriterium „Empathiemangel“ ist, und Studie 5 stellt die Beschreibung der NPS als stabiles andauerndes Muster in Frage. Implikationen für weitere Forschung und für die klinische Praxis werden diskutiert.Narcissistic personality disorder (NPD) is discussed due to its inconsistent conceptualization. The aim of this study was to investigate a sample of NPD patients to collect empirical evidence and discuss the validity and clinical relevance of NPD. Two epidemiological studies are included in this thesis. Study 1 focused on the general mental stress of NPD patients and assesses comorbidities, Study 5 looks at the stability and remission rate of the diagnosis and its criteria. Study 1 found that NPD is associated with general mental stress and high comorbidity rates for affective disorders and substance use disorders, Study 5 found that NPD demonstrates a moderate remission rate of about 53%. In Study 2 and 3, self-related cognitions and emotions were examined. Study 2 investigated explicit and implicit self-esteem. It was determined that NPD is associated with a lower explicit self-esteem and an unaffected implicit self-esteem. Study 3 focused on shame-proneness in NPD. Patients with NPD showed significantly higher explicit and implicit shame-proneness. These results indicate that the narcissistic vulnerability characterized by low explicit self-esteem and high explicit and implicit shame-proneness is necessary in inpatients with a NPD. In Study 4 cognitive and emotional empathy were examined. NPD patients displayed impairment in emotional empathy while cognitive empathy was unaffected. In summary, the findings are in line with the critique that the diagnostic criteria are too narrow to describe the entire manifestation of the disorder. Study 1-3 presented evidence for the narcissistic vulnerability that is not represented by the current diagnostic criteria, Study 4 provided evidence for an unaffected cognitive empathy that is contrary to the seventh diagnostic criteria “lack of empathy”, and Study 5 calls the stable pattern of long duration into question. Implications for further research and clinical practice are discussed
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
Advancing the personalized advantage index (PAI): a systematic review and application in two large multi-site samples in anxiety disorders
No full textAbstract Background The Personalized Advantage Index (PAI) shows promise as a method for identifying the most effective treatment for individual patients. Previous studies have demonstrated its utility in retrospective evaluations across various settings. In this study, we explored the effect of different methodological choices in predictive modelling underlying the PAI. Methods Our approach involved a two-step procedure. First, we conducted a review of prior studies utilizing the PAI, evaluating each study using the Prediction model study Risk Of Bias Assessment Tool (PROBAST). We specifically assessed whether the studies adhered to two standards of predictive modeling: refraining from using leave-one-out cross-validation (LOO CV) and preventing data leakage. Second, we examined the impact of deviating from these methodological standards in real data. We employed both a traditional approach violating these standards and an advanced approach implementing them in two large-scale datasets, PANIC-net ( n = 261) and Protect-AD ( n = 614). Results The PROBAST-rating revealed a substantial risk of bias across studies, primarily due to inappropriate methodological choices. Most studies did not adhere to the examined prediction modeling standards, employing LOO CV and allowing data leakage. The comparison between the traditional and advanced approach revealed that ignoring these standards could systematically overestimate the utility of the PAI. Conclusion Our study cautions that violating standards in predictive modeling may strongly influence the evaluation of the PAI's utility, possibly leading to false positive results. To support an unbiased evaluation, crucial for potential clinical application, we provide a low-bias, openly accessible, and meticulously annotated script implementing the PAI
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
