Salivary and plasma cortisol and testosterone responses to interval and tempo runs and a bodyweight-only circuit session in endurance-trained men

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.     

Teachers’ experience with inclusive education in Singapore

Teachers’ positive attitude is most critically and consistently associated with successful inclusion. However, little is known about teachers’ first-hand encounters with inclusive education in Singapore. We present findings from a qualitative study on inclusion based on focus group interviews with 202 teachers from 41 resourced primary schools. The data were transcribed and coded using Interpretive Phenomenological Analysis and NVIVO software. Two broad clusters identified were teachers’ positive and negative experiences in implementing inclusion. More reference was made to negative than positive experiences. The most dominant negative experience was stress from challenging behaviours and instructional difficulties of catering adequately for diverse needs in the same classroom. The most salient positive experience was satisfaction with pupils’ progress and new learning for teachers. Classroom practices that facilitated inclusion and the value of training in shaping teachers’ attitudes towards inclusion were highlighted.     

The Brazilian experience with agroecological extension: a critical analysis of reform in a pluralistic extension system

ABSTRACT

Purpose: To analyze the Brazilian experience in designing and implementing a recent extension policy reform based on agroecology, and reflect on its wider theoretical implications for extension reform literature. Design/methodology/approach: Using a critical public analysis we characterize the evolution of Brazilian federal extension policy between 2004 and 2015, using political and legal documents as well as recent academic studies for policy frame characterization and implementation analysis. Findings: The case reveals the difficulty of implementing an agroecological extension approach as part of the endogenous development proposal expressed in 2004 PNATER. The agroecological proposal tended to be impaired by a more general demand for diverse public policy programs implementation, facing a series of institutional constraints. A policy reframing process led to a search for alternatives to make it compatible with a federal centralization trend and public administration rules, resulting in a contracting out emphasis. Theoretical implications: The study shows the political economy aspects of extension reform, and how original plans are influenced by path dependence and different and contrasting demands. Practical implications: The study points to the importance of considering political and institutional environments in extension reforms, and indicates a necessity for additional reflection about strategies for scaling up proposals for agroecological and sustainability oriented extension. Originality/value: Few studies are dedicated to understanding the political economy of extension reform, and reform of Brazilian rural extension systems.     

Introducing the Microcomputer into English. II. An evaluation of WILT as a program using a problem-solving approach to learning spelling

Use of the spelling program WILT with a class of mixed-ability third-year secondary-level pupils as part of an evaluation study of programs for language development is reported. The behaviour and language activities characteristic of pupils using WILT are described and 14 categories of language activity identified. The results of an analysis of the language activities of four groups are presented, and the types of learning that are encouraged by WILT are identified. Differences between the pupils' and the class teacher's evaluations of WILT are examined, and the educational value of the program assessed.     

The Word Witch at Work in New Zealand’s <Emphasis Type="Italic">School Journal</Emphasis>, 1960s–1980s: Margaret Mahy’s Writing as a Reflection of Pedagogy and the Spirit of the Times

Between 1961 and 1984 the renowned New Zealand writer, Margaret Mahy, wrote over seventy-five pieces for the School Journal (a graded reading book provided free to New Zealand primary schools since its inception in 1907). It was a liberal humanist period in New Zealand education during which the 1940s’ and 1950s’ rolling reforms implemented by Clarence Beeby had had time to settle, and John Dewey’s progressive system, influenced by ideas associated with European romanticism, had taken hold. With a new appreciation of nationhood and the arts, School Publications sought to publish material that was not only instructional, but also of high literary quality, by reputable New Zealand authors such as Margaret Mahy. Indeed, the School Journal provided Mahy not only with an opportunity to publish her vividly imagined poetry and prose, but also with the additional challenge of writing for an audience of Māori and Pākehā primary school children who needed to learn to read. This article considers ways in which Mahy’s Journal work reflected (or did not reflect) the spirit of the times.     

Introducing the Microcomputer into English. III. An evaluation of TRAY as a program using problem-solving as a strategy for developing reading skills

The models of reading and learning that underlie TRAY are examined, and criteria for selecting texts for classroom use identified. The kinds of language activities characteristic of groups using TRAY are described, and 15 categories of language activity are identified. The results of an analysis of the language activities of three groups are presented. The kinds of learning that are encouraged by TRAY are considered. Pupil and teacher evaluations are found to be favourable. TRAY is concluded to be an example of a good, content-free, problem-solving language development program.     

Maurice Gee’s Brilliant Borrowings of Maurice Gee and Significant Others: Realism and Postmodernism in Gee’s Books for Children and Adults

This paper examines the work of one of New Zealand’s most acclaimed writers, Maurice Gee, and the use of his children’s fiction as an experimental ground for postmodernist techniques further developed in his writing for adults. In particular, it considers Gee’s borrowings of his own and others’ non-fictional and fictional material, to produce richly literary, historical novels. The paper argues that realist and postmodernist features are woven into the children’s and adult books, but that the balance is differently skewed in each. It thus addresses an area largely atypical of the children’s novel, but one that should be of concern to children’s literature critics.
