ABSTRACTThe purpose of this study was to explore the respiratory response of acute interval and continuous exercise (CE) of low and high intensity. Fourteen recreational athletes (7 men and 7 women; VO2max = 35.7 ± 6.1 mlkg–1min–1) performed a bout of continuous and a bout of interval exercise (IE) both consisted of 5-min cycling at low intensity [80% of the power output (W) of the predetermined gas exchange threshold (GET) (80%WGET)] and 5-min cycling at high intensity {WGET plus the work rate corresponding to 50% of the difference between peak power output (PPO) at oxygen uptake (VO2max) test and the WGET [WGET + 0.50 Δ(PPO – WGET)]}. CE compared to IE induced significant higher heart rate and ventilation as well as significant higher levels of mouth occlusion pressure for 0.1 s (P0.1) (P < 0.05) during low and high intensities. Our results indicate that CE stimulates respiration more than IE when the exercise is performed at the same relative intensity. 相似文献

This paper reports on the thoughts 6-year-olds and 9-year-olds have related to the serious issue of air and sea pollution. More specifically, twenty seven 6-year-olds and thirty 9-year-olds attending two state schools in Volos, a small provincial town in Greece participated in the research which assessed the students’ competence to think systemically about dealing with pollution. The study sheds light on whether students are able to identify interrelations between the components of pollution, and clarifies the mental models they hold. Data was collected through drawings and interviews, subsequent analysis of which indicates that students appeared to hold two mental models related to pollution; pollution is connected both spatially and temporally with visible pollutants; and, pollution is connected indirectly with invisible pollutants. The students seemed to exhibit a kind of systemic thinking, which was done unconsciously to a certain degree. Thus it is a challenge for education to enhance students’ systemic thinking in an attempt to bring it to a more conscious level, which will assist them to reconstruct their mental models of pollution. 相似文献

This paper focuses on 119 logotypes that are depicted on European football club kits. The football clubs were selected based on their participation in the first two rounds of the UEFA Champions League competitions and in specific in its first two rounds covering a period of time from 1993 to 2010. Our research interest focuses on the significance of ideological loading in terms of the codes occurring in team logos as symbols of collective identities. Our view was, firstly, that logotypes have absorbed and internalized values and stereotypes from the wider social sphere (paradigmatic axis) and, secondly, that there is a common structuring of logos in terms of codes (syntagmatic axis). Our research is based on socio-semiotic methodology, which is not confined to a formalistic approach of texts, but scrutinizes them as an integral part of a material, socio-economic and political context. The analysis led to a series of important data referring to the structuring of team logos as well as to how these logos are related. 相似文献

Thirty 6-year-olds from two public schools located in a small provincial town in Greece were used as a sample in an explorative study into the mental models young children hold concerning forest destruction and waste. The study also explored how these mental models might be interrelated either within each issue or between issues. The analysis of data collected in interviews indicates that the mental models held by young children appear to be oriented towards two different trains of thought: one that relates to direct actions for the short-term addressing of problems and one that relates to preventive actions and caring for sustainability. Furthermore, children’s own thoughts about their individual contributions to the two environmental problems under study, appear to interrelate with those of collective contributions. More specifically, children seem to share common ideas on the environmental issues discussed as they voiced the opinion, ‘I can help if I do something that addresses the issue'. Implications for education are also discussed in this paper. 相似文献

The aim of this paper is to explore whether in today's changing landscape libraries institutional repositories are used, in order to develop collections of locally produced geospatial data. Furthermore, this study will explore the use of policies in developing geospatial collections in order to reveal whether this tool is necessary for librarians who deal with geospatial collections. Finally, it will also detect the role of cooperation in respect to the development of geospatial collections.This research is addressed to librarians working on geospatial collections so as to ascertain their perceptions since they are considered to be the professionals leading changes. The results demonstrate that Map/GIS libraries, along with analog geospatial collections, tend to develop collections from the data their academic community produces. Librarians seem to be convinced that the formulation of policies, the open access to the data, and the establishment of cooperation among stakeholders will be the critical points to accomplish this goal. 相似文献

A pre-test questionnaire was conducted in a kindergarten and it showed that, although the children were able to give various examples of objects, from their everyday lives, that are similar to solid shapes, the examples they gave for plane figures were also tangible objects. Since it is suggested that geometry instruction has to begin early, children need rich experiences of the connections between plane figures and solid shapes. The researchers provided a picture book as an impetus for kindergartners’ mathematical thinking. We developed and shared a picture book, The Prints, as an auxiliary means for helping kindergarten children identify the print of a solid shape. Through the picture book—which presents plane figures as prints of solids real life objects—children could link plane figures and solid shapes. The research questions we posed were: (a) Can kindergarten children identify the origin of the plane figures presented? (b) Can they relate the objects presented to the plane figures presented? After sharing the picture book—through the storytelling tradition—and completing the related activities, the identification of the print of a solid shape became more accessible and more engaging to children. They were also able to give appropriate examples of plane figures from their everyday lives. This finding was affirmed by the post-test conducted. 相似文献

Research and Technology Organizations (RTOs) and universities are important elements of countries’ innovation systems. As they are both halfway between science and industry, they are often considered to be the same thing. However, recent studies have stressed the differences between the two. In this paper, we analyze the innovative characteristics (impacts and types of innovation and internal R&D investments) of firms that collaborate with RTOs versus universities. Our study is based on statistical analysis of Community Innovation Survey micro-data (CIS 2012). Our results suggest that firms that see RTOs as more important sources of knowledge than universities have a higher probability of developing service innovation, invest less in internal R&D but are less likely to introduce new, groundbreaking innovations into the market. These results have significant policy and management implications, especially regarding the different but complementary contributions offered respectively by RTOs and universities. 相似文献

This article explores the attitudes and opinions of Cypriot primary teachers about the use of the Internet for their personal development and as an educational tool. It also examines the teachers’ concerns about the implementation of the Internet in schools and their opinions about what has to be done in order to ensure its effective integration into the educational settings. The research revealed that Cypriot primary teachers had positive attitudes towards using the Internet both for their professional development and as an educational tool. The only factor that appeared to have a significant positive relationship with the attitudes of the teachers was the degree of confidence in using the Internet. Additionally, teachers considered training in the use of the Internet as the most important need for its effective implementation in primary schools. 相似文献

A recent special education legislation reform in Greece puts emphasis on the inclusion of pupils with special educational needs into mainstream schools. The purpose of the present study was to investigate knowledge of ASD among 67 mainstream nursery and primary classroom teachers, and evaluate the effectiveness of a half-day ASD awareness seminar in increasing their knowledge of the disorder. A self-report ASD Knowledge Questionnaire (ASD-KQ), developed for the purpose of this study, was used before and after the ASD awareness seminar. The results indicated a significant shift from low to moderate/high level of ASD knowledge among teachers with no previous training in special education and/or autism (58.7%), whereas this shift did not reach significance level in the teacher’s group with previous training (16.7%) after the seminar. The present findings have important implications for the development of training programmes of practising teachers. 相似文献
