Activist forest monks,adult learning and the Buddhist environmental movement in Thailand 1

In the tradition of grassroots environmental movements worldwide, activist Buddhist monks in rural Thailand have, since the late 1980s, led a popular movement to protect local forest, water and land resources while at the same time challenging dominant state and corporate ‘economist’ development paradigms. Most famously, these ‘development monks’ (phra nak phathanaa) and ‘ecology monks’ (phra nak anuraksaa) have led local villagers and NGO activists in the symbolic ordaining of large trees and forests (buat paa). They do this in the hope that they will not only protect forests from logging, but also teach local people the value of conserving forest resources. This paper charts the history, philosophy and practice of the activist forest monk movement in Thailand, its contribution to our collective knowledge of adult education in new social movements, and its value to environmental adult education.     

Changes in mechanical properties of sprinting during repeated sprint in elite rugby sevens athletes

This study aimed to analyse fatigue-induced changes in mechanical sprinting properties during a specific repeated-sprint test in elite rugby sevens athletes. Twenty elite rugby sevens players performed ten 40?m sprints on a 30?s cycle with participant’s running back and forth in a marked lane. Radar was used to assess maximal overground sprint performance over each 40?m. Macroscopic mechanical properties (maximal horizontal force (F₀), maximal horizontal power (P_max), maximal ratio of horizontal force (RF_peak), decrease in the ratio of horizontal-to-total force (D_RF), total force and maximal sprinting velocity (v₀)) were drawn from horizontal force velocity relationships, using a validated method applied to the speed–time data. Fatigue-induced changes were analysed comparing the first sprint to an average of 2^nd-4^th, 5^th-7^th and 8^th-10^th. Repeated-sprint ability (RSA) testing induced substantial changes in the maximal velocity component, with a decrease (–15%) in v₀ (effect size (ES)?=?–2.46 to –4.98), and to a lower extent (–5.9%) in the maximal force component F₀ (ES?=?–0.59). D_RF moderately decreased (14%; ES=–0.76–1.11), and RF_peak largely decreased in the later sprints (ES?=?–0.32 to –1.27). Fatigue observed in this RSA test appeared to have a greater effect on the technical ability to produce horizontal force at high velocities, likely due to an alteration in the ability to maintain horizontally oriented force application when velocity increases rather than during the initial acceleration phase, but also the overall force production capacity. The ability to maintain forward-oriented force at high velocities is of central importance for identifying fatigue and monitoring load.     

Crossing the communication divide: Intergroup contact and the desire to learn the outgroup’s language

This paper explores the role of ethnolinguistic vitality and intergroup contact in changing attitudes and the interest to learn Hungarian among Slovak-speaking secondary school students in Southern Slovakia (N?=?225). Several indirect paths linking the all these variables were found. In general, lower local ethnolinguistic vitality of Hungarian decreased intergroup anxiety and increased the quality of contact with members of the Hungarian minority, which led to a more positive attitude toward the Hungarian minority, and enhanced the interest to learn Hungarian.     

How did Light Acquire a Velocity?

We discuss how light acquired a velocity through history, from the ancient Greeks to the early modern era. Combining abstract debates, models of light, practical needs, planned research and chance, this history illustrates several key points that should be brought out in science education.
