Implementation and evaluation of a new methane model within a dynamic global vegetation model: LPJ-WHyMe v1.3.1

Abstract: . For the first time, a model that simulates methane emissions from northern peatlands is incorporated directly into a dynamic global vegetation model. The model, LPJ-WHyMe (LPJ Wetland Hydrology and Methane), was previously modified in order to simulate peatland hydrology, permafrost dynamics and peatland vegetation. LPJ-WHyMe simulates methane emissions using a mechanistic approach, although the use of some empirical relationships and parameters is unavoidable. The model simulates methane production, three pathways of methane transport (diffusion, plant-mediated transport and ebullition) and methane oxidation. A sensitivity test was conducted to identify the most important factors influencing methane emissions, followed by a parameter fitting exercise to find the best combination of parameter values for individual sites and over all sites. A comparison of model results to observations from seven sites resulted in normalised root mean square errors (NRMSE) of 0.40 to 1.15 when using the best site parameter combinations and 0.68 to 1.42 when using the best overall parameter combination.

Intercultural Communication: A Critical Introduction

Abstract: Combining perspectives from discourse analysis and sociolinguistics, the second edition of this popular textbook provides students with an up-to-date overview of the field of intercultural communication. Ingrid Piller explains communication in context using two main approaches. The first treats cultural identity, difference and similarity as discursive constructions. The second, informed by bilingualism studies, highlights the use and prestige of different languages and language varieties as well as the varying access that speakers have to them.The new edition includes:A new chapter devoted to intercultural communication in school that will explore intercultural communication in teaching and learningAn overview of key theoretical discussions related to language in super-diverse contextsLearning objectives, key points, exercises and suggestions for further reading in each chapterCase studies from around the world

Students’ experiences of active engagement through cooperative learning activities in lectures:

Abstract: This article reports on students’ experiences of lectures which included many opportunities for active engagement through cooperative learning activities. At the end of a 13-week semester-long unit, 113 students completed a questionnaire which contained five open-ended questions focusing on the extent to which the students thought that the lecture activities helped them to learn and understand the course content and to maintain their interest and attention during the sessions. Results indicate that students valued the mix of traditional lecturing and cooperative learning tasks, particularly the variety of activities, the opportunities for small-group and whole-class discussions, the clear focus on one or two central ideas, and the authenticity of the tasks.
