Elite football on artificial turf versus natural grass: movement patterns, technical standards, and player impressions     

Andersson H  Ekblom B  Krustrup P 《Journal of sports sciences》2008,26(2):113-122

The aim of the present study was to examine the movement patterns, ball skills, and the impressions of Swedish elite football players during competitive games on artificial turf and natural grass. Time - motion analyses (36 observations) and technical analyses (16 team observations) were performed and 72 male and 21 female players completed a questionnaire. No differences were observed between artificial turf and natural grass in terms of total distance covered (mean 10.19 km, s = 0.19 vs. 10.33 km, s = 0.23), high-intensity running (1.86 km, s = 0.10 vs. 1.87 km, s = 0.14), number of sprints (21, s = 1 vs. 22, s = 2), standing tackles (10, s = 1 vs. 11, s = 1) or headers per game (8, s = 1 vs. 8, s = 1), whereas there were fewer sliding tackles (P < 0.05) on artificial turf than natural grass (2.1, s = 0.5 vs. 4.3, s = 0.6). There were more short passes (218, s = 14 vs. 167, s = 12) and midfield-to-midfield passes (148, s = 11 vs. 107, s = 8) (both P < 0.05) on artificial turf than natural grass. On a scale of 0-10, where 0 = "better than", 5 = "equal to", and 10 = "worse than", the male players reported a negative overall impression (8.3, s = 0.2), poorer ball control (7.3, s = 0.3), and greater physical effort (7.2, s = 0.2) on artificial turf than natural grass. In conclusion, the running activities and technical standard were similar during games on artificial turf and natural grass. However, fewer sliding tackles and more short passes were performed during games on artificial turf. The observed change in playing style could partly explain the male players' negative impression of artificial turf.  相似文献

Students’ Differential Text Production in the Regulative Context of the Classroom     

Ana M. Morais  Helena Antunes 《British Journal of Sociology of Education》1994,15(2):243-263

The research reported in this article is focused on the regulative context of the classroom and attempts to analyse the differential text production by students with different backgrounds (social class, race) and submitted to three different pedagogic practices. These practices, differing in power and control relations, required from the students specific socio‐ affective dispositions. The study explores the extent to which children possessed the specific coding orientation at the level of a given regulative pedagogic practice and also the underlying reasons. Bernstein's conceptual instruments of pedagogic code and also of recognition and realization rules were used to develop the analysis.  相似文献

How students perceive teachers’ nonverbal and verbal communication at agricultural universities in Austria,Slovenia and Albania     

Marija Klopčič  Renata Bažok  Helena Virić Gašparić  Karmen Erjavec 《The Journal of Agricultural Education and Extension》2018,24(5):473-483

Purpose: This study attempts to close the research gap created by the fact that existing studies neglect the problem of how effectively agricultural professors from different European countries communicate. The aim is to identify similarities and differences in the numbers of agricultural professors perceived by students as engaging in verbal and nonverbal immediacy communication.

Methodology: An online survey was conducted among students of agricultural universities from Austria, Slovenia and Albania.

Findings: The results show that professors of agriculture from Austria, Slovenia and Albania should generally not be satisfied with their own communication patterns and should thus try to improve their communication. The result also reveals cultural differences in the shares of agriculture professors employing different communication patterns in Austria, Slovenia and Albania. Compared to Austrian and Slovenian students, their Albanian peers perceive that most of their professors use nonverbal immediacy communication. According to Austrian students, the majority of their professors use verbal immediacy. On the contrary, Albanian students assessed that some of their professors employ verbal immediacy.

Practical Implications: The results show the professors of agriculture should improve the way they communicate to students. In particular, the Albanian professors should improve their verbal communication especially in terms of providing timely and quality feedback to students.

Theoretical implications: The study reveals differences in immediacy communication among countries (Austria, Slovenia and Albania) which the scientific literature considers to have a high-context culture.

Originality/Value: Given that no study has yet examined how students perceive professors’ communication in different European countries, this research helps understand the characteristics of agricultural professors’ communication.  相似文献

Anti-bullying procedures for schools in Ireland: principals’ responses and perceptions     

Mairéad Foody  Helena Murphy  Paul Downes  James O’Higgins Norman 《Pastoral Care in Education》2018,36(2):126-140

The role of the principal is imperative in creating a school climate that nurtures differences and equality at the same time. Policy and legislation in Ireland dictates the responsibility of school principals in preventing and intervening in issues relating to bullying. The current research investigates the extent to which principals consider the impact of bullying on their students and the strategies they take to combat it in their schools. We consider how principals respond to bullying and what supports they feel are missing for them to adhere to relevant policy. A sample of 918 principals from a range of schools across Ireland completed an online survey. The results demonstrated some positive actions by principals such as the provision of anti-bullying policies. However, they also document areas that need more action such as increased access to counsellors and appointing a specific staff member to deal with and tackle bullying in each school. Guidance from the Department of Education and Skills in Ireland on the development and provision of an anti-bullying programme is called for. Results are discussed in light of the current Anti-Bullying Procedures established by the Department of Education and Skills and the Action Plan for Bullying 2013.  相似文献   

Positive teacher–student relationships go beyond the classroom,problematic ones stay inside     

Luce C. A. Claessens  Jan van Tartwijk  Anna C. van der Want  Helena J. M. Pennings  Nico Verloop  Perry J. den Brok 《The Journal of educational research》2017,110(5):478-493

The authors voice teachers' perceptions of their interpersonal experiences with students in both positive and problematic relationships. Interview data from 28 teachers were examined by coding utterances on teacher and student interactions. Results indicate that teachers defined the quality of the relationship mostly by the level of communion (friendly vs. hostile), instead of by the level of agency (in control vs. powerless). Analyses of mentioned teacher and student behavior show a friendly interactional pattern for positive relationships and a hostile pattern for problematic ones. In teachers' perceptions, positive and problematic relationships also differed in context where encounters take place and topic of talk. Contrary to interactions in problematic relationships, encounters in positive relationships were mostly situated outside the classroom context and conversations during these encounters covered a wide range of topics. Implications for teacher education programs are discussed.  相似文献   

“Why Have You Bought a Black Doll?” How Young Children Talk about Diversity     

Helena Stockinger 《Religious education (Chicago, Ill.)》2019,114(3):328-341

Abstract

The qualitative Early Childhood research project analyzes how children, aged five to six years, talk about the dimensions of diversity they recognize in their kindergarten and how two kindergartens in Austria deal with diversity. The children talk about age, gender, size, language, religion, different countries of origin, and skin colors. With regard to the kindergarten organization, there is a tendency toward normativity in dealing with some dimensions of diversity. Religious education may contribute to develop safe and brave spaces where differences are allowed and discrimination against children is avoided.  相似文献
