Home-fitness and active ageing: A review
No full textThe global aging of the population will lead to an increase in social and economic demands, so keeping the elderly active has become a priority. According to the WHO Guidelines, regular physical activity is essential for staying active and healthy and often the best opportunity to do this is at home. Strength activities are frequently set aside because they are considered useless or even risky, but on the contrary have great importance for maintaining of the physical well-being Home-Fitness is an excellent effective and accessible tool for everyone because it brings benefits on a physical and cognitive level, while staying at home. The objective to deepen all aspects related to physical exercise at home in ageing, through a systematic review of the scientific literature, investigating what are the evidence of greatest interest. The evidence determines in depth the relationship between physical activity at home and the elderly, concluding that, those who exercise regularly have a higher quality of life compared to less active subjects. The current COVID-19 pandemic should serve as an impetus for progress in this fiel
Virtual reality and functional recovery
Get PDFWhile there are numerous traditional, non-three-dimensional software, proposed for the rehabilitation purpose, the number of software, based on virtual reality, used to aid the functional recovery of motor and cognitive skills, are drastically low in number even though, in recent years, their use is progressively expanding in all sectors, especially in the one of the health-motor. The benefits of these new technologies compared to traditional techniques alone in motor recovery following neurological traumas have been investigated. VR interventions provide enriched opportunities for integrating goal-oriented tasks and make repeated movements. The use of the headset is necessary to provide a more visually immersive environment (Weber, 2019). The results of functional recovery via immersive VR, have been shown to improve upper limb functions and self-care skills (Abant, 2019). The most interesting thing that emerged from these studies is a better involvement of those who carry out VR activities due to the full immersion of HMDs. It would be interesting in the future to carry out studies concerning motor activity in a VR environment in places with environmental limitations such as penitentiary facilities and retirement homes, also given the simplicity of learning that has emerged from the studies carried out
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
