Caratteristiche antropometriche e composizione corporea di atleti praticanti il bodybuilding e la kickboxing
No full textIn this paper athletes practising bodybuilding and kickboxing were compared, as in these two disciplines weight and body composition have a great importance. The research was carried out on a sample from Sardinia (Italy) constituted by 22 subjects practising bodybuilding and 24 practising kickboxing. The following anthropometric measurements were taken: height, weight, circumferences and skinfold thickness, from which different anthropometric indices were calculated: Body Mass Index (BMI), Waist Hip Ratio (WHR), Arm Muscle Area (AMA), Arm Fat Area (AFA). The percentage of fat mass (FAT%%) was evaluated through skinfold techniques, using Jackson and Pollock (3 skinfolds) and Durnin and Womersley (4 skinfolds) equations. The average value of total height of athletes under scrutiny (172.94±6.45 cm for kickboxers and 172.06±8.98 cm for bodybuilders) was slightly higher than the average value of Sardinians (173.3 cm). Mean BMI for both groups fell within the range of normal weighted, but with a value significantly higher for (24.14±1.71 vs 22.76±1.71, p < 0.05). The two groups of athletes showed a different distribution of muscle mass, located prevalently in the upper limbs for the bodybuilders, in fact they presented higher values of arm circumference and AMA and lower values of biceps and triceps skinfold thickness. Kickboxers presented a lower distribution of subcutaneous fat in the trunk. Moreover, low percentage of fat mass characterize both kickboxers (3 skinfolds=7.70±2.32%; 4 skinfolds=11.53±2.99%) and bodybuilders (3 skinfolds=8.35±3.35%; 4 skinfolds=13.14±3.15%), and it is probably due to the intensive physical activity practised: 7.80±0.79 hours a week for kickboxers and 6.50±1.77 hours a week for bodybuilders.In questo lavoro si sono voluti mettere a confronto sportivi praticanti bodybuilding e la kickboxing, attività per le quali il peso e la composizione corporea assumono una valenza significativa. La ricerca è stata condotta su un campione, di origine sarda, di 22 atleti di bodybuilding e 24 atleti di kickboxing. Sono state rilevate le seguenti misure antropometrici: peso, statura, circonferenze e pliche, con i quali sono stati calcolati: l¿indice di massa corporea (BMI, Body Mass Index), il rapporto vita/fianchi (WHR, Waist Hip Ratio), l¿area muscolare e adiposa del braccio (AMA, Arm Muscle Area e AFA, Arm Fat Area). Il grasso percentuale (FAT%) è stata stimato tramite plicometria, utilizzando le formule Jackson e Pollock (3 pliche) e Durnin e Womersley (4 pliche). Il valore medio della statura totale degli atleti esaminati (172,94±6,45 cm nei kickboxer e 172,06±8,98 cm nei bodybuilder) è di poco superiore alla media regionale sarda di 171,3 cm. Il BMI medio rientra, per entrambi i gruppi, nel range di normopeso, ma con un valore significativamente superiore nei bodybuilder (24,14±1,71 vs 22,76±1,71, p < 0,05). Tra i due gruppi di atleti si è evidenziata una differente distribuzione della muscolarità, localizzata per i praticanti bodybuilding maggiormente nell¿arto superiore, essi registrano infatti valori più alti della circonferenza del braccio e dell¿indice di muscolarità AMA e più bassi valori delle pliche bicipitale e tricipitale, i kickboxer presentano una minor distribuzione di grasso sottocutaneo a livello del tronco. Si è riscontrato inoltre una ridotta massa grassa sia nei kickboxer (3 pliche=7,70±2,32%; 4 pliche=11,53±2,99%) che nei bodybuilder (3 pliche=8,35±3,35%; 4 pliche= 13,14±3,15%), dovuta sicuramente alla rilevante attività fisica praticata: 7,80±0,79 ore a settimana per i kickboxer e 6,50±1,77 ore a settimana per i bodybuilder

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
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
