Changes in body image perception after an outdoor physical education program
Full text linkDescription of the problem and aims Body image is a complex construct that significantly affects people’s quality of life. Body image is related to perceptions and thoughts about one’s own body through an evaluation of size and attractiveness. This construct has been mainly treated in terms of psycho-attitudinal outcomes but there is growing evidence regarding the role of physical education on positive body image. Although there are several studies related to this topic, few researchers focused on how physical education in an outdoor setting may influence body image. This study examines changes in body image of adolescents who followed a twelve-week outdoor physical education program based on walking and running activities compared to equivalent indoor activities. Methodology Self-reported data were collected. Subjects were asked to indicate their Current Body Shape and their Ideal Body Shape by means of a Figure Rating Scale (CDRS) based on drawn silhouettes ranging from extreme thinness to severe obesity. Body Shape Questionnaire 14 (BSQ-14) was also administered to assess the overall body shape dissatisfaction. Conclusions Results showed an improvement after the intervention in body image scores(CDRS and BSQ-14) in those subjects engaged in the outdoor program compared to those who participated in indoor activities who showed a non-significant decrease of the scores. The results indicate that an outdoor physical education program may have a positive effect on how youngsters perceive their body image compared to activities carried out in an indoor traditional classroom context. Outdoor education may facilitate the process of body image perception and representation through self-acceptance and enjoyment of the activity
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
Improvement of the expression of upper limb muscle strength and balance in a group of patients with multiple sclerosis, through a proprioceptive rehabilitation protocol combined with the application of photon emission devices.
Full text linkIn multiple sclerosis (MS) patients, symptoms such as: fatigue, lack of physical energy, spasticity, difficulty in performing movements, and motor coordination disorders, and with tremors, dizziness and postural instability are among the most common complications. Cattaneo et al. (2007) studied the effects of stability training on MS patients and described it as an effective intervention in reducing falls risk, improving stability, and strength. Therefore, the present study aimed to confirm early observations by the application of a proprioceptive rehabilitation program targeting balance and strength on MS patients. 13 subjects with MS, 5 male and 8 female, volunteered in the study. A MAP hand dynamometer was used to determine the handgrip strength, as the maximum isometric grip (MIG), recognized as an important health indicator for determining musculoskeletal function, as well as weakness and disability. Sensor Medica® systems allowed us to carry out baropodometric and stabilometric measurements using the associated program (Freestep® by Sensor Medica®). The device consists in a pressure platform with resistive sensors with conductive rubber. The rehabilitation protocol included: A) 10 minutes of Motomed; B) 10 minutes of Human Tecar proprioceptive path; C) 15 minutes in total of physical exercises; D) 15 minutes of massage therapy of the whole spine All patients wore the photon emission devices TAOPATCH by TAO technologies, according to a protocol used in a previous study (Amato et al., 2021). Testing procedures were carried out before and after the rehabilitation protocol. The paired sample t-test revealed statistically significant improvements for the baropodometric measures (p<0.05) associated with the intervention. In particular, plantar surface pressure, forefoot and hindfoot pressure improved significantly, as well as the maximal and mean foot pressures and the forefoot and hindfoot loads (figure 1a). In addition, the intervention induced a statistically significant improvement in the right (p = 0.023) and left (p = 0.021) handgrip strength (figure 1b). The combination of an adequate and specific rehabilitation protocol combined with the application of the photon emission devices Taopatch, emerged as a valid protocol to improve handgrip strength of the upper limbs and the expression of the body weight on the ground in contrast with the force of gravity. Thus, determining improvements in a cluster of parameters severely decompensated in MS patients
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
BECOMING “PHYSICALLY EDUCATED” TO IMPROVE HEALTH AND WELLBEING: THE MEANINGS OF “EDUCATION” AND “PHYSICAL” IN PHYSICAL EDUCATION
Full text linkIn this contribution, we explained the meanings of “Education” and “Physical” in Physical Education (PE) in the
international framework, as there is a global confusion among PE practitioners. To date, there’s a risk of doing
sports, physical activity, and obesity prevention without Education, or acquiring theoretical knowledge without
movement. Research indicated that social, emotional, physical, and cognitive dimensions are enhanced through PE
and Physical Literacy, that is educating through movement. Thus, laying a strong “physical dimension” platform is
necessary to achieve a “health and physically educated” child. In conclusion, to optimise wellbeing children must be first "physically educated
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
