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
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
Zdravje športnikov v uradnih zapisih mednarodnih športnih zvez udeleženk olimpijskih iger v Tokiju leta 2021
No full textThe International Olympic Committee sets the direction for the development of sport, and international sports federations are responsible for incorporating that direction into their rules to maintain their presence at the Olympics. At the 2021 Tokyo Olympic Games, 33 international sports federations represented with their sports. We have analyzed the statutes of 33 international sports federations based on the keywords "health", "medicine", "doping" and "injuries". Doping is mentioned in all major documents, health is omitted by 30% of federations, medicine is not mentioned by 21% of federations, and only eight international sports federations mention injuries, representing 24% of federations. From the data on doping and injuries in sports, we can conclude that doping is a minor problem compared to injuries. The main reason for acute and chronic injuries could be related to the technical rules for practicing the sport, not to the constitution. If the number of injuries is to be reduced, the technical rules should be changed first, as the injury statistics per sport show.Mednarodni olimpijski komite določa smer razvoja športa, mednarodne športne zveze so odgovorne za vključitev te usmeritve v svoja pravila za ohranitev prisotnosti na olimpijskih igrah. Na olimpijskih igrah v Tokiu 2021 je bilo 33 mednarodnih športnih zvez zastopano s svojimi športi. Analizirali smo statute 33 mednarodnih športnih zvez na podlagi ključnih besed "zdravje", "medicina", "doping" in "poškodbe". Doping je omenjen v vseh pomembnih dokumentih, zdravje ni omenjeno pri 30 % zvez, medicine ne omenja 21 % zvez, le osem mednarodnih športnih zvez omenja poškodbe, kar predstavlja 24 % zvez. Iz podatkov o dopingu in poškodbah v športu lahko sklepamo, da je doping manjša težava v primerjavi s poškodbami. Glavni razlog za nastanek enkratnih in ponavljajočih poškodb bi lahko bil povezan s tehničnimi pravili za udejstvovanje s športom in ne s statutom. Če želimo zmanjšati število poškodb, se morajo spremeniti tehnična pravila, kot kaže statistika poškodb po športih
The Functional Movement Screen’s Relation to Young Tennis Players’ Injury Severity
No full textThis study aimed to explore the relationship between functional movement screen (FMS) scores and injury severity in young tennis players. Additionally, we investigated the effect of the characteristics of the training programme on injury severity. During the annual testing and screening, we assessed 181 tennis players aged between 12 and 18. The Functional Movement Screen was used to measure multiple movement factors, to detect deficits in gross movement quality, to identify movement asymmetries, and to predict general musculoskeletal injury risk. The cohorts’ mean composite FMS score was 16.02 ± 1.98. Players scored higher in shoulder mobility and active straight leg raise, while the lower scores were obtained in the deep squat and rotary stability. We found that the FMS composite scores were higher for players who had not been injured and lower for players who had not trained or competed for >4 weeks due to injury. There was a significant association between the FMS composite score and injury severity. Namely, the group of players who had been injured for >4 weeks, reached the lower average FMS score (14.95). It was found that more hours of tennis practice per week increased, significantly, the injury severity, while more hours of fitness and conditioning practise decreased significantly the injury risk for the 6-months following the FMS testing.El objetivo de este estudio fue explorar la relación entre las puntuaciones de las Pruebas de Movimiento Funcional (FMS) y la severidad de las lesiones en jóvenes jugadores de tenis. Además, se investigó el efecto de las características del programa de entrenamiento sobre la severidad de la lesión. Durante las pruebas y exámenes anuales evaluamos a 181 jugadores de tenis de entre 12 y 18 años de edad. La FMS se utilizó para medir múltiples factores de movimiento, para detectar deficiencias en la calidad del movimiento amplio, para identificar asimetrías de movimiento y para predecir el riesgo general de sufrir lesiones músculo esqueléticas. La puntuación promedio del FMS compuesto del grupo fue de 16,02 ± 1,98. Los jugadores obtuvieron una puntuación más alta en la movilidad de los hombros y en el levantamiento activo de la pierna estirada, mientras que las puntuaciones más bajas se dieron en la sentadilla profunda y la estabilidad rotatoria. Se ha constatado que los jugadores que no se habían lesionado obtuvieron puntuaciones compuestas de la FMS mayores, mientras que las más bajas las obtuvieron los jugadores que no habían entrenado o competido durante más de 4 semanas debido a una lesión. Se encontró una asociación significativa entre la puntuación compuesta de la FMS y la duración de la lesión. Concretamente el grupo de jugadores que había estado lesionados durante más de 4 semanas alcanzaron la puntuación media de FMS menor (14,95). Los jugadores que participaron en más entrenamientos y sesiones de preparación física se ausentaron con menos frecuencia de los entrenamientos y torneos
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
