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

The purpose of this study, to find out how much the relationship between power limbs, eye-hand coordination, and a sense of confidence with the results of the ability to shoot shoots on basketball.This research method uses a correlation method with product moment calculation techniques. The sample amounted to 20 people from all extra-basketball players / athletes in SMK Negeri 4 Kota Pontianak.The calculation results obtained show; 1). There is a positive relationship between Leg Power (X1) with the results of Lay-up Shoot (Y) skills of 68%. 2). There is a positive relationship between hand eye coordination (X2), with the results of Lay-up Shoot skills (Y ) of 42.2%. 3) There is a positive relationship between self-confidence (X3) and the results of Lay-up Shoot (Y) skills of 47.5%.Thus there is a positive relationship between power limbs (X1) eye-hand coordination (X2) and self-confidence (X3) together towards the results of the Lay-up Shoot skill (Y) obtained from the R correlation coefficient of 81.8% . So the conclusions from this study show that power limbs, eye-hand coordination, and self-confidence have a significant relationship with the results of basketball shoot lay-up capabilities.

The Effect Of Massage and Active Streching on Speeding up Blood Lactic Acid Recovery
Full text linkThe accumulation of blood lactic acid after high intensity activities is an acute effect that can contribute to fatigue for sportsmen, therefore it is necessary to do engineering to accelerate recovery. The purpose of this study was to determine the effect of massage and active stretching on the acceleration of blood lactic acid recovery. The research method used in this study is experimental. The research sample was 14 Physical Education students with the same subject design (within subject design) using the time difference between treatments for six days (washed out period). The data taken were blood lactic acid data before and after the engineering of recovery after the sample carried out high-intensity (anaerobic) activity in this study used the form of 30-50 meter interval running activities, then to accelerate the recovery of blood lactic acid after the sample did the activity, namely the recovery technique. massage and active stretching for 5 minutes. The first recovery technique is massage (shaking and tapotement) and the second recovery technique uses active stretching. The results of the first study, the data obtained from the calculation of Sig. 2-tailed (0,000) <0.05, meaning that there is an effect of massage on the acceleration of blood lactic acid recovery, both asym.sig. 2-tailed (0.002) <0.05, meaning that there is an effect of active stretching on the acceleration of blood lactic acid recovery, the three asym.sig. 2-tailed (0.382)> 0.05 means that there is no difference in the effect between massage and active stretching on the acceleration of lactic acid recover

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
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
