In this study, we wished to determine whether the observed reduction in quadriceps muscle oxygen availability, reported during repetitive bouts of isometric exercise in simulated sailing efforts (i.e. hiking), is because of restricted muscle blood flow. Six national-squad Laser sailors initially performed three successive 3-min hiking bouts followed by three successive 3-min cycling tests sustained at constant intensities reproducing the cardiac output recorded during each of the three hiking bouts. The blood flow index (BFI) was determined from assessment of the vastus lateralis using near-infrared spectroscopy in association with the light-absorbing tracer indocyanine green dye, while cardiac output was determined from impedance cardiography. At equivalent cardiac outputs (ranging from 10.3±0.5 to 14.8±0.86 L · min(-1)), the increase from baseline in vastus lateralis BFI across the three hiking bouts (from 1.1±0.2 to 3.1±0.6 nM · s(-1)) was lower (P = 0.036) than that seen during the three cycling bouts (from 1.1±0.2 to 7.2±1.4 nM · s(-1)) (Cohen's d: 3.80 nM · s(-1)), whereas the increase from baseline in deoxygenated haemoglobin (by ～17.0±2.9 μM) (an index of tissue oxygen extraction) was greater (P = 0.006) during hiking than cycling (by ～5.3±2.7 μM) (Cohen's d: 4.17 μM). The results suggest that reduced vastus lateralis muscle oxygen availability during hiking arises from restricted muscle blood flow in the isometrically acting quadriceps muscles. 相似文献

Literacy as a social practice has a fundamental role in children’s lives especially in the early years context, in which social interactions are in the centre of knowledge achievement. Several pieces of research investigate the positive contribution of the arts in children’s literacy development in the early years settings. However, most of them focus on the aspect of emergent literacy and phonological awareness, with some indirect arguments about literacy as a social practice. Having this in mind and the importance of literacy as a social practice, this project was designed. The purpose of this paper is to examine the effects of the arts in the development of literacy as a social practice in the early years settings. The intervention used the ‘Play and Learn through the Arts’ (PLA) programme for a full school year in a case study with 5–6-year-old children in Greece. The outcomes were measured using authentic assessment techniques and a semi-structure interview. The findings showed the positive contribution of the arts in the development of literacy as a social practice in the early years setting. 相似文献

AbstractThis study aims to identify, collect and critical review the research literature on Multilingual Digital Libraries in English language from 1997 to 2012.Design/methodology/approach: The present literature review has followed the rules of systematic review. In particular, the identified relevant papers were categorized based on their expressed aim on two core themes, that of system-centered and user-centered studies. The assigned papers were further analyzed and six sub-themes emerged for the system-centered studies and four for the user-centered studies. Additional categorization was also provided according to type of publication.Findings: The literature concerning Multilingual Digital Libraries is vast and mainly focuses on two aspects the “System” and the “Users”. The majority of papers tried to meet the challenges raised for enabling multilingual information retrieval in Digital Libraries. Unfortunately, these efforts undertaken by a small number of researchers or research groups apparently working in isolation and therefore resulting in the development of numerous different tools and techniques. Relatively few studies have focused on the user and aimed to explore users' behavior and expectations when interacting with Multilingual Digital Libraries. As a result, further research is needed to reach to some tangible and usable findings.Originality/value: This literature review captures the diversity of the research conducted regarding multilingual information access and retrieval in Digital Libraries. It organizes the vast literature in comprehensive themes and sub-themes enabling easy access to specific information.Limitations: This study reviews only papers in English due to language restrictions from 1997 to 2012. 相似文献

This paper reports on a study conducted among Greek kindergarten teachers aiming to explore their conceptual frameworks on a major environmental issue of our times: the ozone layer depletion. The choice of this particular issue was premised on its novelty, complexity and abstractness which present teachers with difficulties in its teaching. A free word association task was employed to identify the associative meaning of the issue among the participant teachers. The study’s results revealed the existence of a simplistic, linear, cause-and-effect scheme in the teachers’ conceptual frameworks, the two poles of which are “solar radiation” and “its harmful results for human health”. Some of the well-known misconceptions and misunderstandings already emerged in previous research also arise in this study. Prominent among them are the deeply rooted confusion between the “ozone hole” and “greenhouse effect”, a general fusion of ideas concerning all environmental problems and an overemphasis on the harmful consequences of the ozone depletion on human health. Implications for kindergarten teacher education are also discussed.The present study is part of a research project that is co-funded by the European Social Fund and National Resources – (EPEAEK II) PYTHAGORAS II. 相似文献

A written questionnaire was used to obtain information regarding Greek kindergarten teachers’ personal views on the concept of Environmental Education (EE). The questionnaire was also designed to obtain the teachers’ views relative to a series of theoretical and methodological issues concerning the application of EE. It was ascertained that the prevalent conception of the kindergarten teachers includes the following: (a) it is directed towards a knowledge-centered type of EE, (b) it is primarily centered on nature and its protection in terms of EE content, (c) it aims not only to shape citizens willing to adopt environmental measures recommended by the experts, but who will also actively participate in social actions for the protection of the environment, (d) it favors learning procedures in the environment with field study activities, (e) it must be compulsory in the kindergarten level. 相似文献

While research has focused on the role of racism in (re)producing ethnic/racial inequalities in education, there is very little research that investigates how variability in minority students’ responses to racism can be explained. By using an ecological approach to integrate existing research on actors’ responses to racism, this study finds that researchers have generally neglected factors and processes situated at the micro- and meso-levels of analysis. Qualitative interview data with Turkish–Cypriot children enrolled in schools in the predominantly Greek-speaking part of the Republic of Cyprus are used to investigate their strategies in response to racism and the factors that explain the observed variability in their responses. The findings suggest the importance of and interactions between factors situated at different levels of analysis, including the level of organizations and social groups and face-to-face interactions in explaining variability in young people’s responses to racism. 相似文献

Teaching culture in the foreign language classroom has been widely debated ever since its importance was recognized. Current research suggests that centralized ‘top down’ curricular policies can become potential constraints to teaching culture and points to the need for adapting curricula for culture-integrated language learning. This study analysed official curriculum documents published in 14 different countries to identify how the sociocultural component to Teaching English as a Foreign Language is reflected in the document. To date, there is scarce research on the place of culture in English as a Foreign Language curricula; hence, the present study aims at filling in a gap in this area. The study points to the following findings: curricula state the importance of culture in language learning and promote an integrative view of teaching language and culture; cultural objectives focus on appreciating cultural diversity, raising cultural awareness and reinforcing students’ positive cultural identity; teachers are portrayed as facilitators (rather than transmitters) of cultural knowledge yet, learners are described as acquiring (rather than discovering) cultural knowledge; curriculum documents focus on cultural knowledge and attitudes towards foreign cultures, rather than on the skills needed for successful interaction. These findings are elaborated and discussed, with potential implications for practice. 相似文献

This research aimed to explore the factors having an effect on enhanced active pupil participation in the context of the sustainable school. The research was applied during a school year to a primary school in Lavrion (Greece), with the participation of two teachers and pupils from two classes of the upper two grades. Action Research was the method selected to organise the research conducted in the framework of a school programme focusing on sustainable waste management. It involved activities both at school and within the local community. An analysis of research results showed that specific perceptions of both pupils and teachers, some of the features of the learning processes adopted, and the current school culture were the determining factors, either facilitating, or inhibiting active pupil participation. The action research enabled teachers not only to identify factors inhibiting active pupil participation, but also to intervene to manage them. 相似文献
