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.

This edited book presents scientific results of the International Semi-Virtual Workshop on Data Science and Digital Transformation in the Fourth Industrial Revolution (DSDT 2020) which was held on October 15, 2020, at Soongsil University, Seoul, Korea. The aim of this workshop was to bring together researchers and scientists, businessmen and entrepreneurs, teachers, engineers, computer users, and students to discuss the numerous fields of computer science and to share their experiences and exchange new ideas and information in a meaningful way. Research results about all aspects (theory, applications and tools) of computer and information science, and to discuss the practical challenges encountered along the way and the solutions adopted to solve them. The workshop organizers selected the best papers from those papers accepted for presentation at the workshop. The papers were chosen based on review scores submitted by members of the program committee and underwent further rigorous rounds of review. From this second round of review, 17 of the conference’s most promising papers are then published in this Springer (SCI) book and not the conference proceedings. We impatiently await the important contributions that we know these authors will bring to the field of computer and information science.

This book defines the nature and scope of insider problems as viewed by the financial industry. This edited volume is based on the first workshop on Insider Attack and Cyber Security, IACS 2007. The workshop was a joint effort from the Information Security Departments of Columbia University and Dartmouth College. The book sets an agenda for an ongoing research initiative to solve one of the most vexing problems encountered in security, and a range of topics from critical IT infrastructure to insider threats. In some ways, the insider problem is the ultimate security problem.

In this comprehensive and detailed analysis of recent research on encouraging reflective practices in TESOL, Farrell demonstrates how this practice has been embraced within TESOL and how it continues to impact the field. Examining a vast array of studies through his own framework for reflecting on practice, Farrell’s analysis comprises not only the intellectual and cognitive but also the spiritual, moral, and emotional aspects of reflection. Reflection questions at the end of each chapter provide a jumping-off point for researchers, scholars, and teachers to further consider and reflect on the future of the field. Providing a holistic picture of reflection, this book is an original compendium of essential research on philosophy and principles, instruments used in studies, and theory and practice.

Higher education is currently undergoing significant changes, and conditions in higher education reflect changing financial, social, and political conditions, which affect both faculty and students. Both the rising costs of education and changes from brick-and-mortar to technologically-driven programs often lead to a change from the traditional space-and-time bound institution to ones that offer cost-effective technologically enhanced programs. Online learning has become an integral and expansive factor in higher education?both in distance learning and as an adjunct to the traditional classroom. Understanding Online Instructional Modeling: Theories and Practices focuses on both theoretical and practical aspects of online learning by introducing a variety of online instructional models as well as best practices that help educators and professional trainers to better understand the dynamics of online learning.

There is an intrinsic conflict between creating secure systems and usable systems. But usability and security can be made synergistic by providing requirements and design tools with specific usable security principles earlier in the requirements and design phase. In certain situations, it is possible to increase usability and security by revisiting design decisions made in the past; in others, to align security and usability by changing the regulatory environment in which the computers operate. This book addresses creation of a usable security protocol for user authentication as a natural outcome of the requirements and design phase of the authentication method development life cycle.

Reflections on Language Teacher Identity Research is the first book to present understandings of language teacher identity (LTI) from a broad range of research fields. Drawing on their personal research experience, 41 contributors locate LTI within their area of expertise by considering their conceptual understanding of LTI and the methodological approaches used to investigate it. The chapters are narrative in nature and take the form of guided reflections within a common chapter structure, with authors embedding their discussions within biographical accounts of their professional lives and research work. Authors weave discussions of LTI into their own research biographies, employing a personal reflective style. This book also looks to future directions in LTI research, with suggestions for research topics and methodological approaches. This is an ideal resource for students and researchers interested in language teacher identity as well as language teaching and research more generally.

This book focuses on the impact of teachers’ leadership identity on their pedagogical and class management choices and proposes a new pedagogical framework, leaderful classroom practices which emerged through collective, concurrent, collaborative, and compassionate interactions between the teacher and students. The interdisciplinary aspect of the book appeals to a wide range of readers from different disciplines and gives readers the opportunity to take a moment and reflect on their leadership identity, recognize the limitations of their practices, and adopt a leaderful pedagogy in their respective disciplines. Establishing an open, democratic, and participatory learning environment for all learners is a major leadership responsibility of teachers, and this book demonstrates how to accomplish this mission both in theory and practice.
