Exercise intensity and energy expenditure during a mini-trampoline rebounding exercise session in overweight women
Objectives The purpose of this study was to estimate the exercise intensity and energy expenditure during a mini-trampoline rebounding training session in a group of overweight women to assess whether such fitness activity meets the guidelines for exercise prescription in adults of the American College of Sports Medicine (ACSM) and whether it can be recommended for an overweight female population. Equipment and methods To achieve the aims of our study, eighteen overweight women (36.7 ± 10.6 years, BMI: 26.8 ± 1.6 kg/m2), were enrolled. All the participants underwent a maximal cardiopulmonary exercise test and the main physiological variables were recorded. Afterwards, the subjects performed a mini-trampoline rebounding exercise session where exercise intensity and energy expenditure were measured with a heart rate monitor, a rating perceived exertion scale and a portable armband device, respectively. Successively, the physiological responses obtained from these two activities were compared. Results The average heart rate throughout the mini-trampoline exercise session, lasting 46.1 ± 5.0 min, was 132.3 ± 7.7 bpm, corresponding to 72.2 ± 3.3% of that obtained in the preliminary maximal test. The estimated energy expenditure of participants to mini-trampoline rebounding exercise session was 6.9 ± 0.8 kcal/min, corresponding to a total of 317.3 ± 45.7 kcal for the duration of the entire session. Conclusions Our results showed that mini-trampoline rebounding exercise is a vigorous physical activity, which can be identified as an effective way to achieve an optimal level of training, as indicated by the ACSM guidelines
Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
Verso la macroregione adriatico-ionica?
Questo contributo parte considerando la regione adriatico-ionica come “unità nella varietà”: nonostante le differenze e le divisioni storiche, infatti, essa appare accomunata da un patrimonio imponente di risorse, attrazioni e infrastrutture. È da questo patrimonio che sembra partire la macro-regione, un’idea ed uno strumento che ambiscono a dare un valore aggiunto in chiave di sviluppo ed in particolare di sviluppo turistico. Tale strumento, promuovendo la collaborazione intercostiera e interregionale, può quindi rafforzare la competitività adriatico-ionica in un mercato turistico sempre più globale ed agguerrito.
Il mio contributo parte da quest’ultimo aspetto: nel turismo di oggi, nell’età globale in cui viviamo, le comunità locali e le regioni hanno più opportunità di “essere sé stesse” ed offrire le proprie peculiarità sul mercato. Queste peculiarità, infatti, oggi sono più facilmente conoscibili grazie alla diffusione e circolazione delle informazioni, ma anche più facilmente accessibili grazie allo sviluppo dei trasporti.
In questo quadro introduco l’idea della macro-regione, ripercorrendone brevemente la storia ed alcuni sviluppi concreti negli ultimi anni. Illustro inoltre alcuni programmi e prodotti turistici che sono sorti nella prospettiva di valorizzare l’aspetto intercostiero e lo sviluppo regionale.
Ciò che emerge è un quadro ricco di esperienze ed iniziative, in cui hanno un ruolo chiave i programmi finanziati dall’Unione Europea ma anche tanti attori regionali. L’idea di macro-regione, dopo un calo negli anni scorsi, sembra quindi tornata alla ribalta, fermi restando alcuni limiti e problematiche che la rendono ancora un “progetto incompiuto”
Appropriate Similarity Measures for Author Cocitation Analysis
We 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
We 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
We 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
