Resistance training
The potential outcomes achieved by resistance training programme design depend on the relationship between training variables, such as volume, intensity, rest periods, duration and frequency of training, and the mechanical variables, namely selection and type of exercise, in addition to the devices used to provide resistance (Naclerio et al. 2011). Correct exercise technique is a basic but prerequisite requirement of all resistance training programmes, and it is not limited to the level of performance, the programme goal or expected outcomes (Colado and Garcia-Masso 2009). To guide participants through correct exercise technique, instructors must fully understand the limits of the secure range of motion, joint positions that increase the risk of injury (and how to avoid those positions), the training status and history of participants and the technical model of the desired movement.
Evidence accumulated over the last decade has demonstrated that injury risk in resistance training is significantly low compared to other activities such as team sports and gymnastic or fighting sports (Myer et al. 2009). When practiced regularly, following a well-designed programme, resistance training has been shown to be safe and effective (Jones et al. 2000; Myer et al. 2009). The level of safety is maximised when resistance exercises are performed under the supervision of qualified instructors who know how to effectively teach this type of training. Such professionals may provide the most effective interventional approach for reducing the probability of strength training–related injuries, regardless of the age of participants (adults, teenagers or children) (Faigenbaum et al. 2011; Colado and Garcia-Masso 2009). Some authors have made reference to contraindicated exercises, such as the dead lift or deep squat, that can be performed safely following a sound training process and within the optimal range of motion, volume and intensity and technical ability of the participant (Naclerio and Forte 2011). This chapter focuses on the importance of controlling exercise technique and maintaining correct posture during resistance exercises. It also analyses the mechanisms available for warm-ups and safety recommendations for controlling resistance training exercise. Finally it reviews the dose–response resistance training outcomes for athletes and recreational novice, intermediate and advanced practitioners
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
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
