A protocol of intermittent exercise (shuttle runs) to train young basketball players
No full textThe purpose of this study was to set up a protocol of intermittent exercise to train young basketball players. Twenty-one players were asked to complete (a) an incremental test to determine maximal oxygen uptake (VO2max), the speed at the ventilatory threshold (vthr) and the energy cost of "linear" running (Cr) and (b) an intermittent test composed of 10 shuttle runs of 10-second duration and 30-seconds of recovery (total duration: about 6 minutes). The exercise intensity (the running speed, vi) was set at 130% of vthr. During the intermittent tests, oxygen uptake (VO2) and blood lactate concentration (Lab) were measured. The average pretraining VO2 calculated for a single bout (131 ± 9 ml · min(-1) kg(-1)) was about 2.4 times greater than the subjects' measured VO2max (54.7 ± 4.6 ml · min(-1) · kg(-1)). The net energy cost of running (9.2 ± 0.9 J · m(-1) · kg(-1)) was about 2.4 times higher than that measured at constant "linear" speed (3.9 ± 0.3 J · m(-1) · kg(-1)). The intermittent test was repeated after 7 weeks of training: 9 subjects (control group [CG]) maintained their traditional training schedule, whereas for 12 subjects (experimental group [EG]) part of the training was replaced by intermittent exercise (the same shuttle test as described above). After training, the VO2 measured during the intermittent test was significantly reduced (p < 0.05) in both groups (-10.9% in EG and - 4.6 in CG %), whereas Lab decreased significantly only for EG (-31.5%). These data suggest that this training protocol is effective in reducing lactate accumulation in young basketball player
Milano attraverso la crisi: lo sviluppo immobiliare, l’abitabilità, le politiche
No full textIl lungo ciclo della rigenerazione urbana “a leva immobiliare” tipi-co di molti sistemi urbani contemporanei ha contribuito a riplasmare il volto della città di Milano a partire dai primi anni ’90, dando visibilità e concretezza ai profondi cambiamenti che hanno accompagnato la transizione terziaria e la globalizzazione dell’economia.
Gli investitori privati sono stati i protagonisti di questa stagione di rinnovamento urbano caratterizzata dalla diffusione dei “programmi complessi” quali strumenti per coordinare tra loro interventi pubblici e privati, tesi a migliorare l’assetto e la qualità urba-na.
Le ricadute sul sistema dell’abitare e sulle opportunità di accesso all’abitazione per i cittadini sono al centro della prima parte di questo contributo. Nonostante il dinamismo che ha contraddistinto Milano in questa fase di trasformazione (che ha visto un brusco arresto con l’avvento della crisi economico-finanziaria del 2007) e alcuni ri-sultati positivi nel panorama dei programmi complessi, la chiave di lettura proposta assume che gli interventi di nuova edificazione o di recupero dell’esistente abbiano impattato su un sistema di accesso all’abitazione divenuto nel tempo molto rigido e selettivo. Negli ultimi anni, la domanda di abitazione è andata riarticolandosi attorno a nuove criticità rispetto al passato, portando in luce ampie zone di fra-gilità abitativa connotate da problemi di affordability e incertezza, a fronte di un complessivo miglioramento dei problemi di disagio più tradizionali legati alla qualità e alle dimensioni dell’alloggio.
La seconda parte del contributo presenta il recente passaggio da un modello di sviluppo connotato da un approccio additivo legato alla promozione degli interventi privati, ad una nuova stagione nella quale la visione progettuale generale (contenuta nel Piano di Governo del Territorio, 2012) si coniuga con una ricostruzione selettiva di stra-tegie pubbliche. Vengono qui discussi gli esiti, ancorché provvisori, delle sperimentazioni in atto nel campo della produzione di affordable housing, e segnalati gli aspetti mag-giormente innovativi e promettenti
Politiche abitative per gli stranieri nella Venezia Giulia
No full textIl testo ricostruisce la situazione della parte più interessata dal confine del Friuli Venezia Giulia dal punto di vista del rapporto tra politiche abitative, politiche di accoglienza degli stranieri, progetti e pratiche di integrazione. Osserva quindi se e come le idee di integrazione e multiculturalismo cha hanno nei secoli caratterizzato questi territori abbiano oggi, sui temi dell'inclusione e dell'accoglienza, anche abitativa, sviluppato esperienze di rilievo e potenzialmente interessanti anche per altri contesti nazionali
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
