Engaging the theme of appearance dissatisfaction expressed by women who had undergone cosmetic surgery, and its subsequent impacts upon body image and self-perception, this study concludes that shame and narcissism are interrelated processes, whereby the evaluations and amendments to appearance, and the notions of self and social acceptance which underpin it, are negotiated.
This book provides comprehensive insights into the theory, models, and unique characteristics of intelligent reflecting surface (IRS) and its appealing applications in wireless information and power transmission for B5G/6G. It is organized as follows: Chapter 1 gives an overview of the fundamentals of IRS, including the signal and channel models of IRS, its hardware architecture, advantages and practical constraints. Chapter 2, 3 and 4 focus on how to optimize the joint design of active and passive beamforming for three types of IRS-aided wireless information/energy transmission systems, namely IRS-aided power transfer (WPT), IRS-aided simultaneous wireless information and power transfer (SWIPT) and IRS-aided wireless powered communication networks (WPCN). Chapter 2 specifically presents a general framework design for IRS-aided WPT systems from the perspectives of energy beamforming design and channel estimation, while the dynamic IRS beamforming design is also discussed. Chapter 3 thoroughly studies the IRS-aided SWIPT for achieving better R-E trade-off, wherein two different designs based on weighted sum-power maximization at energy users (EUs) and under individual quality-of-service (QoS), requirements at both information users (IUs) and EUs are investigated. Chapter 4 presents three paradigms of IRS-aided WPCN, i.e., IRS-aided half-duplex (HD) WPCN, IRS-aided full-duplex (FD) WCPN and IRS-aided multiple-input-multiple-output (MIMO) FD WPCN. The authors present some related emerging topics, e.g., active IRS aided wireless communications and IRS-aided unmanned aerial vehicle (UAV) communications in chapter 5. This book targets postgraduate students studying electrical engineering and computer science, and can be used as a secondary textbook. Professionals, researchers and engineers working in wireless networks will also find this book useful as a reference.
Student Empowerment in Higher Education brings together the accumulated knowledge and experience of many accomplished teachers and students from higher education institutions around the world, and has much to offer those who are engaged in higher education, as students, teachers or support staff. The authors offer personal reflections in teaching, learning, mentoring, assessment, hands-on activities, course design and student identities in higher education across the globe, supported by academic research and scholarship. Readers are provided with a window into tried and tested empowering practices in varying contexts, enabling them to see what works and what does not, alongside the challenges and possibilities. A distinctive feature of this book, and its paramount strength, is that it explores best practices in student empowerment, whilst reflecting on matters of teaching and learning that are familiar to students and teachers alike, and also explores practices in a variety of disciplines. The intention of these volumes, therefore, is not only to inform readers about the diverse learning and teaching approaches of the authors, but, most importantly, to facilitate processes of student empowerment and promote reflection on teaching and learning practices. "In recent decades, higher education policy discourse has persistently implied that a university education is 'delivered' to students under the impersonal banner of 'the student experience'. Not only does this commodify the diverse, individual experiences of students into one marketable product, it also creates false barriers and power dynamics between students and their teachers. In Student Empowerment in Higher Education, the students and lecturers who collaborated to write this important volume have literally blown such misleading notions out of the window! I highly recommend each varied and autonomous chapter to learn what really inspires confidence and success in university students." Professor Sarah Hayes, Professor of Higher Education Policy, University of Wolverhampton "The two volumes of Student Empowerment in Higher Education offer the reader rich and varied examples and understandings of student empowerment from around the world. The authors provide reflective accounts of learning and teaching from diverse perspectives and disciplines, which focus on many different areas of practice in higher education. It is this variety that will appeal to many readers, as the source of ideas and inspiration for numerous possible routes to empowerment. With many chapters co-authored by students and staff, the book models the collective responsibility students and staff have for enhancing student empowerment."

"During her 70-year ministry the author spoke, through her pen, to young people, to church members, and to the world in the The Youth's Instructor, the Review and Herald, and The Signs of the Times. Selections for this book have been drawn from these three periodicals as well as from her books and previously unpublished manuscripts and letters"--Foreword.
The Common European Framework of Reference for Languages (CEFR) and its Companion Volume have established themselves as an indispensable reference point for all aspects of second and foreign language education. This book discusses the impact of the CEFR on curricula, teaching/learning and assessment in a wide range of educational contexts, identifies challenges posed by the Companion Volume and sheds light on areas that require further research and development. Particular attention is paid to three features of the two documents: their action-oriented approach, their focus on plurilingualism, and the potential of their scales and descriptors to support the alignment of curricula, teaching/learning and assessment. The book suggests a way forward for future engagement with the CEFR, taking account of new developments in applied linguistics and related disciplines.
