This Element aims to elucidate the concept of language teacher agency by exploring the 'what' question, offering major conceptualisations of agency and explaining how they shape the way we approach teacher agency. The authors then continue with the 'why' question, and elaborate on the reasons that language teacher agency matters, based on a discussion of the varied purposes of teacher agency at multiple levels. They also acknowledge that teacher agency does not operate alone, and discuss how it intersects with such concepts as teacher identity, emotion, belief and knowledge. Based on this, they identify ways to promote teacher agency through making changes to contexts and/or actors. They then introduce the concept of collective agency and propose a multi-layered model based on an illustrative study. The Element ends with a call for a trans-perspective on understanding language teacher agency so as to facilitate the professional development of language teachers.

This book presents up-to-date theory and methods of statistical hypothesis testing based on measure theory. The so-called statistical space is a measurable space adding a family of probability measures. Most topics in the book will be developed based on this term. The book includes some typical data sets, such as the relation between race and the death penalty verdict, the behavior of food intake of two kinds of Zucker rats, and the per capita income and expenditure in China during the 1978-2002 period. Emphasis is given to the process of finding appropriate statistical techniques and methods of evaluating these techniques.

This open access book provides a comprehensive overview of the author’s in-depth insights into the theory, prediction methods, and developmental trends of creep instability and failure in coal-rock masses within mining stopes. The content primarily covers topics such as creep instability of coal-rock masses in stopes, creep instability of surrounding rock in roadways, large-scale roof creep instability, creep instability of overlying strata in goaf, rockburst, gas outburst, and principles and prediction of roof creep instability in fully mechanized mining faces. Additionally, it explores theoretical advancements in analyzing the energy principles of coal-rock masses and acoustic wave monitoring of coal-rock systems. This book serves as a valuable reference for professionals and researchers in mining engineering, mine construction, underground space engineering, and geotechnical engineering, as well as for faculty and students in related fields.
