The aim of this study was to quantify the type of offensive sequences that result in goals in elite futsal. Thirty competitive games in the Spanish Primera Division de Sala were analysed using computerised notation analysis for patterns of play that resulted in goals. More goals were scored in positional attack (42%) and from set pieces (27%) compared to other activities. The number of defence to offense “transitions” (n = 45) and the start of offensive plays due to the rules of the game (n = 45) were the most common type of sequences that resulted in goals compared to other patterns of play. The central offensive zonal areas were the most common for shots on goal, with 73% of all goals scored from these areas of the pitch compared to defensive and wide zones. The foot was the main part of the body involved in scoring (n = 114). T-pattern analysis of offensive sequences revealed regular patterns of play, which are common in goal scoring opportunities in futsal and are typical movement patterns in this sport. The data demonstrate common offensive sequences and movement patterns related to goals in elite futsal and this could provide important information for the development of physical and technical training drills that replicate important game situations. 相似文献

The protective action of remote ischaemic preconditioning (RIPC) has been demonstrated in the context of surgical interventions in cardiology. Application of RIPC to sports performance has been proposed, but its effect on the electrocardiogram (ECG) during exercise remains unknown. This exploratory study aims to measure the changes in ventricular repolarization observed during exercise following RIPC in healthy subjects. In an experimental randomized crossover study, 17 subjects underwent two bouts of constant load exercise tests at 75% and 115% of gas exchange threshold (GET). Prior to exercise, they were allocated to either control or RIPC intervention with four cycles of 5?min of ischaemia followed by 5?min of reperfusion. ECG was continuously recorded during the protocol. QT and RR intervals were measured every 30?s (on an average tracing of the preceding 10?s). Although the time course of RR intervals did not differ between the two interventions (p?=?.56 at 75% GET and p?=?.74 at 115% GET), a significant shortening of QT intervals (measured from Q onset to T end) was observed during exercise (mean?±?standard deviation of RIPC vs. control: ?32?±?19?ms at 75% GET (p?.001) and ?34?±?12?ms at 115% GET (p?.001)) as well as during recovery (?21?±?8?ms at 75% GET (p?.001) and ?16?±?11?ms at 115% GET (p?.001)). This effect was not present at rest. These RIPC-related changes were clearly identifiable on the QT–RR loops after hysteresis reduction. RIPC therefore induces heart rate-independent shortening of QT intervals that is revealed during exercise. 相似文献

This study analyses the university choices of male and female students in Italy over the 2003–2012 period and for two sub-periods before (2003–2008) and after (2009–2012) the 2008 financial crisis. The analysis is guided by human capital, signalling and preference theories and implemented through a competing destinations model that controls for the socio-economic features of both the region of origin and destination. The findings show that in the post-crisis period, males became more career-oriented in their university choices due to increasingly constrained and competitive labour markets. The constrained post-crisis labour markets led females to focus more on the educational experience than on future employability prospects. Our results suggest that the financial crisis maintained or even widened gendered social roles as they relate to university choices; specifically, males assumed an even greater career-centred family role, whereas females adopted more adaptive lifestyles that potentially place them at a disadvantage in the labour market and in society in years to come. 相似文献

This study is an item analysis of the Matching Familiar Figures Test-20. We examined error scores in the Matching Familiar Figures Test-20 to determine the influence of the difficulty of the test on the assessment of reflection–impulsivity. The sample included 700 participants aged between 6 and 12 years. The results obtained from the corrected item–total correlation showed moderate but significant values for the discrimination index in all age groups, although the lowest values were found in the 6-year-old group. The item difficulty data show that the test is quite difficult for 6-year-old participants and quite easy for 12-year-old participants, and more likely to show individual differences between these ages. The results suggest that the difficulty of the MFFT20 is appropriate for children between 6 and 12 years. However, because of some floor and ceiling effects, the results of this test for ages 6 and 12 should be interpreted very cautiously, especially for the 6-year-old group. 相似文献

Inequality of opportunity for educational achievement in Latin America: Evidence from PISA 2006–2009
We evaluate how far away six Latin American countries stand from a normative goal of equality of opportunity for educational achievement in PISA 2006–2009. We work with alternative characterizations of types: gender, school type (public or private), parental education, and their combinations. Following Checchi–Peragine's (2010) non-parametric method, we find that inequality of opportunity for educational achievement in Latin America ranges from less than 1% to up to 25%, depending on the year, the country, the subject and the specification of circumstances. These magnitudes are substantial with respect to what is found in comparator countries. Parental education and school type prove to be important sources of inequality of opportunity, contrary to gender. By means of sensitivity analyses, while most results show small to moderate variation in terms of magnitudes, in ordinal terms (rankings) they remain quite stable. Brazil stands out as the most opportunity-unequal country of the sample. 相似文献

This study presents the results of a web‐based questionnaire administered to 166 second language teachers and designed to obtain information about their use and needs of information and communication technologies (ICTs) as related to language learning (LL). Analyses revealed that, although teachers believe that second language acquisition is primarily driven by social interaction, they seldom use computers as a means to foster collaboration or interaction. ICTs are thought to be very helpful in individual learning scenarios but not for the interactive dimension of LL. Very few teachers incorporate interaction‐oriented digital tools in their language teaching, probably due to their self‐acknowledged deficient training in ICTs. However, instructors stated that they would like to introduce new interaction tools in their computer‐aided courses, which clearly shows the need for both teachers’ training in ICT and the technological development of proper interactive functionalities. Die Auswertung computervermittelter Technik von Zweit‐Sprachlehrern: Kollaboration und Interaktion in CALL Diese Studie zeigt die Ergebnisse einer Umfrage, die dafür entworfen wurde, Information darüber zu erhalten, die etwa Zweit Sprachlehrer verwenden, und den Bedarf an Informations‐ und Kommunikationstechniken (ICTs), die mit Sprachlernen (LL) generell verbunden sind. Analysen ergaben, dass, obwohl Lehrer glauben, dass der Erwerb einer zweiten Sprache in erster Linie von sozialer Interaktion angetrieben wird, sie selten Computer als Hilfsmittel verwenden, um Kollaboration oder Interaktion zu fördern. Es wird angenommen, dass ICTs sehr in einzelnen Lernzenarien, aber nicht für die interaktive Dimension von LL hilfreich sein kann. Sehr wenige Lehrer integrieren interaktionsorientierte digitale Werkzeuge in ihre – möglicherweise durch ihre selbstanerkannte unzulängliche Ausbildung in ICT – eigene Sprachlehre. Jedoch gaben Ausbilder an, dass sie neue Interaktionswerkzeuge in ihren computergestützten Verläufen einführen möchten. Das zeigt den Bedarf nach Ausbildung beider eindeutig: Lehrer in ICT und der technologischen Entwicklung von korrekten interaktiven Funktionalitäten. L’évaluation dela technologie informatisée chez les professeurs de langue seconde :collaboration et interaction dans l’enseignement des langues assisté par ordinateur (CALL) Cette étude présente les résultats d’une enquête conçue pour recueillir des renseignements sur la façon dont les professeurs de langue seconde utilisent et ont besoin des TICE spécifiques pour l’apprentissage linguistique. Des analyses ont révélé que les professeurs utilisent rarement les ordinateurs pour stimuler la collaboration et l’interaction et ce, bien qu’ils croient que l’acquisition d’une langue seconde est avant tout entraînée par l’interaction humaine. Ils pensent que les TICE sont très utiles dans des situations d’apprentissage individuel mais pas pour la dimension interactive de l’apprentissage des langues. Très peu nombreux sont les professeurs qui intègrent des outils numériques à orientation interactive dans leurs cours de langues, ceci étant probablement dÛ à une formation informatique déficiente qu’ils reconnaissent eux‐mêmes. Certains professeurs ont toutefois indiqué qu’ils voudraient introduire de nouveaux outils interactifs dans leurs cours assistés par ordinateur ce qui fait clairement apparaître le double besoin de formation aux TICE pour les professeurs et d’un développement technique de fonctionnalités interactives appropriées. Una evaluación de la tecnología basada en ordenadores por parte de los profesores de la segunda lengua: colaboración y interracción en aprendizaje de idiomas asistido por ordenador Esta investigación presenta los resultados de una encuesta diseñada para conseguir información sobre las necesidades específicas para el aprendizaje de lenguas y el uso de las tecnologías de la información y la comunicación (TICs) por parte de 166 profesores de segunda lengua. Los análisis han revelado que, aunque los profesores creen que la adquisición de una segunda lengua está fundamentalmente impulsada por la interacción social, en realidad hacen poco uso del ordenador para incentivar la colaboración y la interacción. Los docentes piensan que las TICs son muy útiles para la modalidad de aprendizaje individual pero no para la dimensión interactiva del aprendizaje de idiomas. Son pocos los profesores que incluyen herramientas digitales con orientación interactiva en sus cursos de idiomas, probablemente, como confiesan ellos mismos, debido a las carencias de su propia formación digital. No obstante, algunos profesores señalan que quieren introducir nuevas herramientas interactivas dentro de sus cursos asistidos por ordenador, lo que claramente demuestra la necesidad tanto de una buena formación en TICs para los profesores como del desarrollo tecnológico de nuevas funcionalidades interactivas adecuadas. 相似文献
