Download or read book The Spartan Scytale and Developments in Ancient and Modern Cryptography written by Martine Diepenbroek and published by Bloomsbury Publishing. This book was released on 2023-11-16 with total page 265 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers a comprehensive review and reassessment of the classical sources describing the cryptographic Spartan device known as the scytale. Challenging the view promoted by modern historians of cryptography which look at the scytale as a simple and impractical 'stick', Diepenbroek argues for the scytale's deserved status as a vehicle for secret communication in the ancient world. By way of comparison, Diepenbroek demonstrates that the cryptographic principles employed in the Spartan scytale show an encryption and coding system that is no less complex than some 20th-century transposition ciphers. The result is that, contrary to the accepted point of view, scytale encryption is as complex and secure as other known ancient ciphers. Drawing on salient comparisons with a selection of modern transposition ciphers (and their historical predecessors), the reader is provided with a detailed overview and analysis of the surviving classical sources that similarly reveal the potential of the scytale as an actual cryptographic and steganographic tool in ancient Sparta in order to illustrate the relative sophistication of the Spartan scytale as a practical device for secret communication. This helps to establish the conceptual basis that the scytale would, in theory, have offered its ancient users a secure method for secret communication over long distances.

Download or read book Theory and Practice in Second Language Teacher Identity written by Karim Sadeghi and published by Springer Nature. This book was released on 2022-09-16 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book brings together the current theory, research and practical perspectives from different parts of the world on language teacher identity in an attempt to better understand the nature of identities teachers in different contexts develop. By linking theory to pedagogy, the book examines how second language teacher identities are shaped and explores the various links between teacher identities and variables that affect the formation of identities. Theory and Practice in Second Language Teacher Identity includes a foreword by Jack Richards (University of Sydney and RELC), an afterword by Peter de Costa (Michigan State University) and holds 20 invited chapters by established and active scholars and teacher educators to discuss the various aspects of in-service and pre-service second language teacher identity development. It also addresses the way the COVID-19 pandemic has impacted teacher identities and examines under-researched issues, such as the intersection between gender and race in second language teacher identity development and identity construction in second languages other than English. What does it mean to be a teacher of English as a second language in an age of globalization, new media, technological revolution and de-institutionalized knowledge? How do teachers gain pre-service and in-service expertise, a sense of professional identity, and educational integrity? And how have they dealt with the extra-burden imposed by the pandemic? This thought-provoking volume offers valuable perspectives on these important issues in the professional development of English teachers worldwide. — Prof. Claire Kramsch, University of California, Berkeley, USA. The way we see ourselves and are seen by others influences our social and professional interactions. Teacher identity and sense of agency is therefore not merely a matter of research interest for it impacts learners and learning, which makes the topic of this book extremely important. With chapters located in a wide range of countries – from USA to Australia via UAE, Thailand and others – and drawing on a variety of research methods, the book synthesizes extant research and develops many new research avenues. It does so not only with theory in mind but with practical lessons for teachers and teacher educators and thus becomes an essential volume for our libraries and studies. — Prof. Michael Byram, University of Durham, UK. In this compelling collection, co-edited by Karim Sadeghi and Farah Ghaderi, the authors address key questions about language teacher identity in contemporary applied linguistics: What is the relationship between language teacher identity and language teacher agency? To what extent does ideology impact language teacher identity? How do language teachers navigate an increasingly globalized and unequal world? Authors from different regions of the world draw on diverse methodologies to share insightful research on both pre-service and in-service language teacher identity, making an important contribution to applied linguistics and TESOL at a time of great social and educational change. — Prof. Bonny Norton (FRSC), University Killam Professor and Distinguished University Scholar, University of British Columbia, Canada. “Theory and Practice in Second Language Teacher Identity” captures recent thinking about language teacher identity. The broad array of excellent chapter contributions explores multiple dimensions of identity, from teacher agency and emotions to the disruptive effects of the Covid pandemic on teachers’ professional lives and practices. The studies draw on a number of theoretical perspectives and demonstrate the use of both familiar and innovative research methodologies. The relevant topics, the up-to-date bibliographic sources, and the useful research findings make this edited volume an essential addition to your bookshelf. — Prof. Gary Barkhuizen, University of Auckland, New Zealand.

Download or read book Writing and Identity written by Roz Ivani? and published by John Benjamins Publishing. This book was released on 1998 with total page 389 pages. Available in PDF, EPUB and Kindle. Book excerpt: Writing is not just about conveying 'content' but also about the representation of self. (One of the reasons people find writing difficult is that they do not feel comfortable with the 'me' they are portraying in their writing. Academic writing in particular often poses a conflict of identity for students in higher education, because the 'self' which is inscribed in academic discourse feels alien to them.)The main claim of this book is that writing is an act of identity in which people align themselves with socio-culturally shaped subject positions, and thereby play their part in reproducing or challenging dominant practices and discourses, and the values, beliefs and interests which they embody. The first part of the book reviews recent understandings of social identity, of the discoursal construction of identity, of literacy and identity, and of issues of identity in research on academic writing. The main part of the book is based on a collaborative research project about writing and identity with mature-age students, providing: - a case study of one writer's dilemmas over the presentation of self;- a discussion of the way in which writers' life histories shape their presentation of self in writing;- an interview-based study of issues of ownership, and of accommodation and resistance to conventions for the presentation of self;- linguistic analysis of the ways in which multiple, often contradictory, interests, values, beliefs and practices are inscribed in discourse conventions, which set up a range of possibilities for self-hood for writers.The book ends with implications of the study for research on writing and identity, and for the learning and teaching of academic writing.The book will be of interest to students and researchers in the fields of social identity, literacy, discourse analysis, rhetoric and composition studies, and to all those concerned to understand what is involved in academic writing in order to provide wider access to higher education.
