The relevance of media in football coaching: the case of José Mourinho’s leadership approach     

Fernando Ilharco 《Soccer & Society》2019,20(2):307-324

This article examines the leadership approach of the football coach José Mourinho, particularly of the relevance of the media for his top performance at Porto (2002–2004), Chelsea (2004–2007), Inter Milan (2008–2010) and Real Madrid (2010–2013). The perspective from which we analyse the work of Mourinho in that period, and his presence in the media, is based on what science calls the paradigm of complexity. This is a relational perspective which, in this case, means not only focusing upon the actions ‘central’ to the activity in question – the technique, tactics, physical preparation and so on – but, with particular relevance, detail and in an integrated fashion, also focusing on the media and the cultural context in which the activity takes place. Key to the transformational work of José Mourinho is his presence in the media, the managing of fame, the challenges and ambitions of the players, the fans and the general public. At stake is a personification of a global system of significance.  相似文献   

High-Resolution Ultrasonic Imaging of Artworks with Seismic Interferometry for Their Conservation and Restoration     

Deyan Draganov  Jürg Hunziker  Karel Heller  Karin Gutkowski  Fernando Marte 《文物保护研究》2018,63(5):277-291

Artworks are an inseparable part of the cultural heritage of societies and provide us with a unique look at cultural developments through time and space. For the best possible conservation, it is paramount to know the constituent materials, condition, and construction techniques of the objects (e.g. painting on wood, fresco, sculpture). Such information is required not only for the surfaces of the objects, but also for the interiors; in the imaging discipline, this is known as depth imaging. Here, we introduce a new method for non-invasive depth imaging as an alternative to traditional non-invasive methods when the latter cannot be used to obtain the required information. We use ultrasonic transverse-wave transmission measurements and turn them into virtual reflection measurements. We achieve this by applying seismic interferometry with active sources. Obtaining reflection measurements by seismic interferometry allows us to apply an advanced imaging technique – prestack depth migration, as used in seismic exploration – to produce a high-resolution depth image of an object. We apply our method to ultrasonic data recorded on a mockup of a painting on a wooden support. We validate our method by comparing our results with an image from X-ray computed tomography.  相似文献

Development and initial validation of a scale to measure emotional abuse among school children aged 13-15 years in Sri Lanka     

Fernandopulle S  Fernando D 《Child abuse & neglect》2003,27(10):1087-1099

OBJECTIVE: To develop a scale to measure emotional abuse among school children aged 13-15 years in Sri Lanka that can be used in field settings. METHOD: Emotional abuse was defined based on available literature. Review of literature and discussions with a panel identified 85 items indicating abusive behaviors. Content validity and social acceptability were achieved by getting the views of this same panel and parents, respectively. Item analysis and assessment of validity were carried out based on the responses to the draft instrument by 105 children aged 13-15 years attending a school in an urban slum area. The test-retest reliability of the scale was assessed using the responses from 144 students from a different school. Criterion validity was established by comparing the independent assessments of a psychiatrist for the presence or absence of emotional abuse with the respective scores of the children on the scale. RESULTS: The scale developed to assess emotional abuse included 46 items having a Cronbach alpha of .89. The test-retest reliability was .73. A cutoff score of 95 was identified at a sensitivity of 76.9% and a specificity of 51.4%. CONCLUSIONS: A scale that had a satisfactory level of reliability and validity was socially acceptable, which could be used in school settings in Sri Lanka was developed to enable identification of emotional abuse among school children aged 13-15.  相似文献   

Preconceptions and relations used by children in the construction of food chains     

Leticia Gallegos  Maria E. Jerezano  Fernando Flores 《科学教学研究杂志》1994,31(3):259-272

This study shows two aspects: the predator–prey relations and the preconceptions held by children (9–10 years old) on the construction of food chains. The subjects of the study were 506 fourth-, fifth-, and sixth-grade children from the Mexican education curriculum. The conclusions are based on a single application of an instrument after a lecture in the classroom. The instrument consists of three tasks. The outcome showed that the classification of herbivorous and carnivorous is based in children's preconceptions of size and ferocity. These preconceptions guide the children's selection of the higher-level predator in the construction of a food chain. Another element used by children is the predator-prey relation in the construction of a food chain. The results shed light on the difficulties students have at higher education levels in the resolution of food webs and the relationships with ecosystems.  相似文献   

Knee joint position sense of roller hockey players: a comparative study     

João Venâncio  Diogo Lopes  Joaquim Lourenço  Fernando Ribeiro 《Sports biomechanics / International Society of Biomechanics in Sports》2016,15(2):162-168

This study aimed to compare knee joint position sense of roller hockey players with an age-matched group of non-athletes. Forty-three male participants voluntarily participated in this cross-sectional study: 21 roller hockey players (mean age: 23.2 ± 4.2 years old, mean weight: 81.8 ± 9.8 kg, mean height: 180.5 ± 4.1 cm) and 22 age-matched non-athletes (mean age: 23.7 ± 3.9 years old, mean weight: 85.0 ± 6.2 kg, mean height: 181.5 ± 5.0 cm). Knee joint position sense of the dominant limb was evaluated using a technique of open-kinetic chain and active knee positioning. Joint position sense was reported using absolute, relative and variable angular errors. The main results indicated that the group of roller hockey players showed significantly lower absolute (2.4 ± 1.2º vs. 6.5 ± 3.2º, p ≤ 0.001) and relative (1.7 ± 2.1º vs. 5.8 ± 4.4º, p ≤ 0.001) angular errors in comparison with the non-athletes group. In conclusion, the results from this present study suggest that proprioceptive acuity, assessed by measuring joint position sense, is increased in roller hockey players. The enhanced proprioception of the roller hockey players could contribute to injury prevention and improved performance during sporting activities.  相似文献   

REEARCH REPORT

This paper addresses the concept of geological time as used by students who face tasks that demand three types of skills: to locate events in time, to order them according to time calendar, and to manage time intervals. The empirical study consisted of asking high school students as well as technical school students to carry out tasks that required the use of the three previously mentioned components. It was found, first, that students frequently used erroneous temporal labels, which shows a lack of knowledge that would allow them to locate events within the context of geobiologic data. Second, the students did not store the representation of a succession of events, but were nevertheless able to create it by means of the deductive use of previous knowledge. Finally, the importance of having an appropriate representation of geological time intervals became patent while observing the students' difficulties in understanding geologic changes.  相似文献   

On not being able to read or speak Malayalam: language and region in Kerala     

Fernando Rosa 《Inter-Asia Cultural Studies》2013,14(2):214-234

Abstract

This paper attempts to read aspects of language, history, and literariness historically from the perspective of both Brazil and Kerala. It is also an attempt to compare two very distinct places from within a framework centred on the South. Initially, region and nation are discussed, as well as modernity and development, and the issue of thinking South–South connections from an anthropological perspective. Next, the matter of the complex connected histories of Kerala within the Indian Ocean is mentioned, including Portuguese colonial history. The image and influence of Latin America in Kerala is briefly brought up, especially in what concerns literary influence. There follows an extended discussion of issues of literacy and the rise of the novel in Kerala as well as the historical intricacies of the construction of Malayalam as a modern medium. A contrast with the literary construction of modernity in Brazil is made, and the importance of English in Kerala is accordingly highlighted as well as the issue of the coloniality of the Portuguese within Brazil's complex creolized history. An analysis of the pioneering novel of Chandumenon is offered, and a comparison with a novel in Brazil is subsequently sketched. The different historical contexts of nineteenth century Brazil and Kerala are stressed. The close interrelatedness between issues of language, nation, and region is emphasised as well as the internal complexities of modernity in both regions.  相似文献   

The core musculature in male prepubescent tennis players and untrained counterparts: a volumetric MRI study     

Joaquin Sanchis-Moysi  Fernando Idoate  David Álamo-Arce  José A.L. Calbet  Cecilia Dorado 《Journal of sports sciences》2017,35(8):791-797

The effects of exercise on the core musculature have not been investigated in prepubescents. The main purpose of the present study was to determine the volume and degree of asymmetry of rectus abdominis, obliques and transversus abdominis, quadratus lumborum, iliopsoas, gluteus and paravertebralis muscles in prepubescent tennis players and in untrained boys. The muscle volume was determined using magnetic resonance imaging (MRI) in 7 male prepubescent tennis players and 10 untrained controls (mean age 11.0 ± 0.8 years, Tanner 1–2). After accounting for height and body weight as covariates, the tennis players had 14–34% greater volume than the controls in all the muscles analysed (P < 0.05) except in paravertebralis, dominant quadratus lumborum and non-dominant gluteus, which had similar volumes in both groups (P = NS). Compared to controls, the tennis players displayed a greater degree of asymmetry in quadratus lumborum and rectus abdominis (3% vs. 15%, P < 0.01 and 8% vs. 17%, P = 0.06, respectively). The level of asymmetry of obliques and transversus abdominis, iliopsoas, gluteus and paravertebralis muscles was similar in both groups (P = NS). In conclusion, tennis playing at prepubertal ages induces a selective hypertrophy of the core musculature and exaggerates the degree of asymmetry of quadratus lumborum and rectus abdominis compared to untrained boys.  相似文献   

Representation of the cell and its processes in high school students: An integrated view     

Fernando Flores  Ma Eugenia Tovar  Leticia Gallegos 《International Journal of Science Education》2013,35(2):269-286

This paper presents an integrated view of the ideas and conceptual problems of high school students with respect to the cell, its processes, structure and relation to the functions of multicellular organisms. The theme of cell has divided into eight topics, with a questionnaire for each topic. In these topics, different levels of representation and understanding are distinguished between general considerations about plants and animals, those connected with processes at organ and system levels and, finally, the level of cell processes. Data from 1200 students were analysed. Results show that students have an analogical mechanism that establishes an isomorphism between the representation of the functioning of multicellular organisms of cell processes. A series of problems in understanding was also shown. Results imply that these problems are mainly due to students' lack of differentiation between some processes at organism and organ level, and have important implications for learning this subject. Finally, some suggestions are made for teaching.  相似文献
