The perceptual – Cognitive skills of combat sports athletes: A systematic review
Full text linkThe aim of this review is to provide evidence of how practicing combat sports can shape the perceptual – cognitive skills of athletes. This is because they must be adept at selecting the relevant stimuli in order to anticipate the attack and decide how counterattack their opponent in order to achieve victory. A systematic search was conducted on PsycINFO, Scopus and Web of Science via the combination of specific keywords. 31 research articles were included. Different aspects of perceptual–cognitive skills were analysed, such as complex cognitive skills and basic cognitive functions. The investigations were divided by the methods and stimuli used. The results are reported in three chapters: one analysed the research conducted with realistic stimuli (videos/pictures), another chapter investigated the studies with simulated scenarios, while the last chapter examined the basic cognitive functions. Following this is a chapter which, instead, analysed an important aspect for future studies: perceptual–cognitive training. The studies revealed better general anticipation skills with real and simulated stimuli, and better cognitive functions with regards to attention for experts than novices. However, a comprehensive analysis is needed to understand the results which emerged from the investigation. Moreover, the review aims to encourage possible future research in the topic area

No full textThe role of the extra physical activity on memory storage and psychosocial features
Full text linkThe present research investigated the role of the physical activity on cognitive functions and psychosocial characteristics. Pre-adolescent children of a middle School of Rimini participated to extra physical activities (EPA) organised by the school. They performed a Free Recall memory Test (Nielson, Radtke & Jensen, 1996) and filled the self-esteem questionnaire (Rosenberg, 1965) and their results were compared with a group of students that did not performed the activity proposed (non-EPA). Moreover, to control the level of physical activity of the sample, participants filled the International activity questionnaire. The results showed that the students who participated to the extra physical activities had high self-esteem compared to the non-EPA group, while no differences between the groups emerged from the Free Recall Memory test
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
Breaking the sedentary: investigating the effects of active breaks on physical Activity and psychosocial well-being in primary school children
No full textPurpose: Sedentary behavior is a growing concern and has been linked to various health problems (Janssen et al., 2010). Moderate to vigorous Physical Activity (PA) Active Breaks (ABs), performed during sedentary periods, may be helpful in promoting physical activity and well-being in developmental ages. However, despite promising results, ABs are not widely used in schools (Biddle et al. 2016; Roset et al., 2020). Therefore, this study investigated the effect of an ABs intervention on PA levels and psychosocial aspects in primary school children.
Methods: A non-randomized controlled design was employed. The sample consisted of 67 primary school children (35 F and 32 M—avg. age 8.79 ± 0.94 y.). Throughout a three-month duration, children were engaged in 10-min ABs sessions twice a day during the cur- ricular school activities. PA levels were measured using the Physical Activity Questionnaire for Children (PAQ-C), and an ad-hoc ques- tionnaire was created to measure well-being and time-on-task behavior before and after ABs intervention. The questionnaire con- tained three subscales: well-being, concentration, and learning. Results: Results showed an increment in the PA levels (F = 19.80, p \ 0.001) and a higher scores on the Classroom Behavior Ques- tionnaire in the well-being subscale (F = 4.18, p = 0.04). Concentration subscale did not reveal differences between the pre- and post-intervention (F = 1.67, p [ 0.05) while learning subscale revealed lower score in the post- compared to the pre-intervention (F = 18.81, p < 0.001).
Conclusions: Even though this study follows a non-randomized controlled design, in accordance with existent literature (e.g., Janssen et al., 2010), its results offer compelling evidence for the effectiveness of ABs in promoting PA and psychosocial well-being among primary school children. This evidence is important for the classroom climate and the quality of the teaching–learning processes. However, the learning and concentration subscales did not produce the expected results, and they could be influenced by other variables. Therefore, our further investigations are orienteed to gain a com- prehensive understanding of this phenomenon.

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
Exploring the Interplay Between Sport Modality and Cognitive Function in Open- and Closed-Skill Athletes
Full text linkThe degree to which each sport modality relies on cognitive visual skills is hitherto under-researched. This study sought to further understanding of the relationship between sport modality and visual search ability, visual working memory, and reasoning. Ninety-five participants took part in the present study. In order to assess visual search ability, we employed the Visual Search Task. Visual working memory was assessed through the Corsi Block Tapping – Backwards Task. Reasoning abilities were assessed through the Cognitive Reflection Task. Results indicate that visual search skills appear to benefit to a higher extent from open-skill sports when compared to closed-skill sports. It is important to emphasize, however, that this result was associated with a small effect size. Moreover, the present findings indicate that closed-skill athletes do not differ in terms of visual search abilities, working memory, and reasoning abilities when compared to control individuals
Intermittent training: The benefits in football
Full text linkThe aim of this study is to verify the effectiveness of an intermittent training methodology in groups of boys belonging to the "Giovanissimi" category of 9-a-side football. The sample is made up of 10 athletes aged 14-15. The sporting season was divided following phases, that is, starting from a preparatory phase and then arriving at the competitive phase, the agonistic one. For the evaluation of the qualitative and quantitative data, each athlete was subjected to anthropometric tests (height, weight, BMI) and spinal flexibility tests both at entry and exit; for the evaluation of endurance, strength, speed, speed and agility the following tests were used: yo-yo Test, Sargent test, T-Test Agility, M test (20m adapted), Speed test 5m, 10m and 20mThrough the statistical model of the t-test for dependent samples, the effectiveness of the method used is evident. The data reveals significant increases for yo-yo Test, Sargent test, M (20m) test, T-Test agility. For the other tests carried out at the exit, there are no significant increases, because they are short-distance tests that show little increase, as the rapidity and speed, in this period of the developmental age, do not produce improvements for the morpho-functional adaptations specific. It has been shown how young boys, sedentary or moderately trained, can obtain benefits thanks to the proposed training, following an adequate programming and planning of training sessions according to their needs
