Abstract

The aim of this study was to examine the acute response to plasma and salivary cortisol and testosterone to three training protocols. Ten trained endurance athletes participated in three experimental trials, such as interval training (INT), tempo run (TEMP) and bodyweight-only circuit training (CIR), on separate days. Blood and saliva samples were collected pre- and 0, 15, 30 and 60 min post-exercise. Peak post-exercise salivary cortisol was higher than pre-exercise in all trials (P < 0.01). After INT, salivary cortisol remained elevated above pre-exercise than 60 min post-exercise. Salivary testosterone also increased post-exercise in all trials (P < 0.05). Plasma and salivary cortisol were correlated between individuals (r = 0.81, 0.73–0.88) and within individuals (r = 0.81, 0.73–0.87) (P < 0.01). Plasma and salivary testosterone was also correlated between (r = 0.57, 0.43–0.69) and within individuals (r = 0.60, 0.45–0.72), (P < 0.01). Peak cortisol and testosterone levels occurred simultaneously in plasma and saliva, but timing of post-exercise hormone peaks differed between trials and individuals. Further investigation is required to identify the mechanisms eliciting an increase in hormones in response to CIR. Furthermore, saliva is a valid alternative sampling technique for measurement of cortisol, although the complex, individual and situation dependent nature of the hormone response to acute exercise should be considered.  相似文献   

Functional reading difficulties in Denmark     

Carsten Elbro  Susan Møller  Elisabeth Munk Nielsen 《Reading and writing》1995,7(3):257-276

In this first Danish study of adult reading skills, 1124 adults between 18 and 67 years of age participated in an interview about reading habits and skills, and 445 were tested individually at home using six common texts. Great care was taken to ascertain that subjects were representative of the whole adult population and that the texts covered most types of everyday reading. Three percent of the participants were found to have severe functional reading difficulties and a further 9 percent to have moderate difficulties. Regression analyses found several unique predictors of reading difficulties: age (adults over 45 years reading more poorly than younger adults), limited basic education, no vocational training nor higher education, and a small amount of reading needed at work. The rate of poor readers was about four times higher among persons with low income than among others. Men and women read equally well although men tended to rate themselves lower as readers than women did. Methodological issues and some educational implications are discussed.  相似文献

Towards Competent Systems in Early Childhood Education and Care. Implications for Policy and Practice     

Mathias Urban  Michel Vandenbroeck  Katrien Van Laere  Arianna Lazzari  Jan Peeters 《European Journal of Education》2012,47(4):508-526

The close connection between the quality of provision for young children and professionaliation of the field has long been supported by international research. That the two are inseparable aspects of one picture is beginning to become accepted at European policy level, as evident in recent high level EU policy documents. This article explores the reciprocal relationship between quality and professionalisation, drawing on the findings of the study on ‘competence requirements in early childhood education and care’ (CoRe), jointly conducted by the University of East London and the University of Gent, and funded by the European Commission. Based on a review of literature in several European languages and data from a 15-country survey and seven in-depth case studies, CoRe has identified systemic conditions for a professionalisation of the entire early childhood system, beyond the formal qualification levels of individual practitioners. The article argues for a critical and systemic reconceptualisation of professional practice in a competent system.  相似文献   

Self‐assessment methods in writing instruction: a conceptual framework,successful practices and essential strategies     

Kristen Nielsen 《Journal of Research in Reading》2014,37(1):1-16

Student writing achievement is essential to lifelong learner success, but supporting writing can be challenging for teachers. Several large‐scale analyses of publications on writing have called for further study of instructional methods, as the current literature does not sufficiently address the need to support best teaching practices. Self‐assessment methods in writing instruction present meaningful ways to promote student writing achievement through reflection and meta‐cognition during the writing process. Self‐assessment practices are described in publications across the academic disciplines where writing is required, and close investigations of the methods are also published in the research fields of literacy, English education and composition. This study aims to bridge these fields to construct a clear and comprehensive understanding of self‐assessment methods. Self‐assessment encompasses a wide range of practices and varied terminology. It is essential to clarify effective methods of self‐assessment and to disseminate practical information to educators. This paper presents the findings of an analysis of the literature yielding: (1) a theoretical framework for self‐assessment methods in writing instruction; (2) an overview of concepts/practices; (3) a list of literature‐supported strategies for effective classroom use derived from a study of a vast body of literature. Results strongly support self‐assessment as a means to foster student writing achievement, middle school through higher education. Delineated strategies can assist instructors with self‐assessment implementation.  相似文献   

Today's news — tomorrow's context: A dynamic model of news processing     

Hans Mathias Kepplinger  Gregor Daschmann 《广播与电子媒介杂志》2013,57(4):548-565

We are proposing a feedback model of news processing, assuming that news reception is guided by media input as well as by existing cognitive structures. However, these structures are in turn shaped by former media coverage. In our study we examine viewers’ processing of TV news, comparing objective news content (content analysis) to subjective meaning of news stories (viewer interviews). Results show that viewers interpret information about new events in the context of past events, themselves mainly a reflection of former media coverage.  相似文献   

The Most Important Thing: Students with Reading and Writing Difficulties Talk About their Experiences of Teachers' Treatment and Guidance     

Cecilia Nielsen 《Scandinavian Journal of Educational Research》2013,57(5):551-565

Dyslexia is a well-known phenomenon and help and assistance are offered to pupils and students who experience literacy difficulties on a regular basis. But what help do they need and want? In this article the responses people with reading and writing difficulties/dyslexia give to this question are discussed. What, if we take the student's own viewpoint, is the most important thing the teacher can do? The students never mention any particular teaching methods. What appears as important to them is that the teacher sees them as individuals, not just as dyslectics, understands the special difficulties with which each individual must grapple, and provides the students with suitable tools for their learning as well as necessary time and space.  相似文献   

Scaffold instruction at the workplace from a situated perspective     

Klaus Nielsen 《Studies in Continuing Education》2013,35(3):247-261

This article proposes the need to address scaffold instructions from a situated learning perspective. Based on an empirical study of how apprentice bakers learn their trade, it is claimed that studies of learning at the workplace yield important insights into our understanding of scaffold instructions. Seen from the perspective of the apprentices, scaffold instruction represents access to more responsibility in practice, it supports their identities as future bakers and they learn bodily know-how. When scaffold instruction failed, it was often in relation to situations where the apprentices were placed in marginal positions in the community of practice or in relation to a central workplace situation.  相似文献   

Changes in BSc Business Administration and Psychology students’ learning styles over one,two and three years of study     

Tine Nielsen 《Studies in Educational Evaluation》2013

Knowledge on general or discipline-specific changes in the learning styles of university students can be utilised in the design and execution of courses, but little is known of such changes. The study examined the changes in the learning styles of three year groups of BSc Business Administration and Psychology students from admittance to one, two and three years later for the three year groups respectively. Learning styles were measured using the Danish Self-Assessment Learning Styles Inventory, which is an adaptation of Sternberg's MSG Thinking Styles Inventory within the theory of mental self-government. The Hierarchic and Oligarchic learning styles decreased significantly for all three year groups. The Judicial learning style increased significantly for the year groups who had studied for two and three years. The Global learning style increased significantly for the year group who had studied for one year. The findings are discussed in relation to comparable research.  相似文献   

Diagrams of Europeanization: European education governance in the digital age     

Mathias Decuypere 《教育政策杂志》2013,28(6):851-872

Abstract

European education governance is increasingly affected by and effectuated through digital means. This article presents an analysis of the way in which Europe is increasingly deploying digital technologies, and more specifically websites, in order to shape and communicate its education policies. Drawing on the notion of the diagram as the multimodal combination of texts and visuals into a single plane, the article scrutinizes two websites that play a central role in the production and distribution of policy data: first, the European Commission’s Directorate Education and Culture website presenting the Education and Training monitor; second, the Open Education Europa website stimulating the deployment of Open Education practices in Europe. Conceived as active devices, various diagrams on these websites are analyzed in view of the operations they perform. It is argued that these diagrams portray related interplays of absence and presence, enact specific spaces into being, and call for specific ways of taking action upon the reality they purport to represent. As such, diagrams have become an integral part of European education governance in the digital age.  相似文献
