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
Isuzu D-max pearl white - japanese dominator
No full textPanuje przekonanie, że jeśli coś jest do wszystkiego, to tak naprawdę jest do niczego. Zapewne jest w tej maksymie sporo racji, jednak nie można jej odnieść do pick-upów. Samochody w tej klasie w niesamowity sposób gwarantują wygodną jazdę w trasie, posiadając jednocześnie świetne predyspozycje do pracy. W dodatku, jeśli tym pick-upem jest Isuzu D-max Pearl White, do tego zestawu cech dołącza także oryginalny, nietuzinkowy wygląd, wyróżniający go na tle konkurencji.There is a widespread belief that if a thing is intended as good for everything, it is good for nothing. Perhaps this is quite right, but the saying connot be applied to pick-ups. Vehicles of this class guarantee in an amazing way comfortable ride on the road, while being perfectly fit for work purposes. In addition, if it is about Isuzu D-max Pearl White, this set of features is completed with an original, unconventional appearance, distinguishing it from the competition
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
The modified D-max is a valid lactate threshold measurement in veteran cyclists
No full textThe ageing process has the potential to impact upon the manner in which an athlete responds to training stimuli. This study investigated if power output (PO) and heart rate (HR) at the modified D-max lactate transition threshold (D-max) was comparable with the mean HR and power that could be sustained during a 30-min laboratory time trial (TT30) in veteran athletes. Nine veteran (¡Ý35 years) cyclists performed an incremental exercise test to determine PO and HR at D-max, and peak physiological values. Participants then performed a TT30 during which mean HR and PO were measured for comparison with D-max values. The PO and HR at D-max were significantly correlated with the mean PO and HR during the TT30 (r=0.95, p<0.001 and r=0.88, p=0.002, respectively). Bland and Altman plots revealed a close agreement between D-max and average values sustained during the time trials for PO (95% CI=−14 to +3W) and HR (95% CI=−6 to +3bpm). This study has demonstrated that in veteran cyclists the D-max is accurate in predicting the highest average PO and HR that can be sustained during a 30-min time trial
