This book addresses the fundamental theory and key technologies of narrowband and broadband mobile communication systems specifically for railways. It describes novel relaying schemes that meet the different design criteria for railways and discusses the applications of signal classification techniques as well as offline resource scheduling as a way of advancing rail practice. Further, it introduces Novel Long Term Evolution for Railway (LTE-R) network architecture, the Quality of Service (QoS) requirement of LTE-R and its performance evaluation and discusses in detail security technologies for rail-dedicated mobile communication systems. The advanced research findings presented in the book are all based on high-speed railway measurement data, which offer insights into the propagation mechanisms and corresponding modeling theory and approaches in unique railway scenarios.It is a valuable resource for researchers, engineers and graduate students in the fields of rail traffic systems, telecommunication and information systems.

Understanding the Dynamics of Teacher Agency, Resilience, and Identity in the Neoliberal Age focuses on the complexity of teachers' agency, resilience, and identity across various contexts. Neoliberal educational policy technologies have been constantly (re)shaping educational professionalism, subjectivity, teaching, and evaluation. Within this climate, teacher agency, resilience, and identity are vital factors for maintaining teachers' well-functioning and well-being. Moreover, teacher agency, resilience, and identity do not exist independently but reinforce each other constitutively, which enable teachers to see beyond challenge and fluctuating confidence and withstand pressure. The educational contexts in this book encompass rural, immigrant, preservice education, special education, internationalized school contexts, etc. Theoretically, this book disentangles the conceptual understandings and methodological considerations of teacher agency, resilience, and identity. Practically, the contributors from various countries and regions explore how various contexts influence teacher agency, resilience, and identity in the neoliberal age.
