Multi-scale Mechanics of 2D Triaxially Braided Composites: Characterization, Mechanics and Machine-Learning Based Modelling presents the latest advances in this important research field. The book begins with a brief introduction to these materials including their mechanical features, damage and failure mechanisms and typical applications. The contents are then divided into three main sections on experimental characterization; mechanics-based modeling and machine-learning based modeling approaches. By taking a multi-scale modeling approach, that includes progressive damage and impact simulation, as well as theoretical modelling, machine-learning and multi-scale mechanics aspects, the author presents key findings in this important field. A systematic introduction is given to the multi-scale and machine-learning based modeling approach, along with their corresponding source codes for the progressive damage model. Then an up-to-date theoretical model is also presented, as well as, high-efficient finite element mesh of the unit cell, for conducting multi-scale analysis and design of these materials and structures. Numerical examples are also presented to illustrate the application of presented methods for quasi-static and impact problems. To enhance the reader’s understanding numerous engineering case studies are also included, together with examples of material/structure optimization. The book provides the latest knowledge and methodology for the design and analysis of aerospace structures and other materials technologies, guiding the researcher to understand this cutting-edge research framework.Presents experimental, analytical, and numerical studies of two-dimensional triaxially braided compositesProvides cutting-edge knowledge on progressive failure simulationIncludes clarification of failure mechanisms under various loading conditionsPresents the latest advances on multi-scale modeling methodsDiscusses challenges and future prospectives on multi-scale mechanics of textile composites

Public Relations Planning: A Practical Guide for Strategic Communication provides students with an in-depth understanding of the steps involved in planning and executing a successful PR campaign. Taking a strategic approach to the subject, the authors bring years of practical experience to the project, helping students see how theoretical elements fit together in reality, and preparing them for the workplace. At the same time, the book goes beyond an introductory discussion of the theory of PR planning, incorporating material from cutting-edge research in the field.This fully updated second edition explores current trends and consequences surrounding the COVID-19 pandemic; covers the latest technological tools and techniques, as well as the ever-changing landscape of social media; and examines the role of data analytics in the PR decision-making process. Examples and vignettes have been updated so that they reflect the current state of the global PR environment, whilst learning objectives, key term definitions, and chapter exercises facilitate comprehension.Providing a solid foundation to the PR planning process, this text is core reading for advanced undergraduate, postgraduate, and executive education students studying Public Relations Strategy, Public Relations Campaigns, and Strategic Communications.Online resources include PowerPoint lecture slides, a test bank, answers for end-of-chapter questions, and instructor notes for the case studies.Public Relations Planning is featured on the International Public Relations Association website.

This book adopts a qualitative research methodology to explore novice teachers’ professional development (TPD) under the background of the New Curriculum Reform in mainland China. With a purposeful sampling strategy, in-depth, semi-structured interviews were employed to collect data from twelve novice primary school teachers. As the specific design of the qualitative method and research procedures have been demonstrated, this book could be reading material for courses such as Qualitative Research Methodology and would be beneficial for undergraduate and postgraduate students learning qualitative research.In addition, this book provides suggestions for pre-service and novice teachers. The study found that although TPD programs and better welfare are desirable, collegial support from seniors, internet resources and online courses, and self-reflection were more direct and effective in enhancing professional growth and reducing negative emotions that developed from challenges in classroom management, workload, and accountability. This book also suggests three directions for the future development of TPD to school leaders and policymakers. First, more training on classroom management and time management is helpful as poor classroom management and excessive workload were the causes of teacher burnout. Second, more school-level mentoring is wanted because it is considered more effective than the state and individual-level opportunities of TPD. Third, more development opportunities for teachers in rural areas are required to improve their professional competence and narrow their gap with their urban counterparts.
