High-Speed Networks: A Tutorial (Practical Networking)
by Elias Bou-Harb Jorge Crichigno Elie Kfoury Nasir GhaniThis book provides practical knowledge and skills on high-speed networks, emphasizing on Science Demilitarized Zones (Science DMZs). The Science DMZ is a high-speed network designed to facilitate the transfer of big science data which is presented in this book. These networks are increasingly important, as large data sets are now often transferred across sites. This book starts by describing the limitations of general-purpose networks which are designed for transferring basic data but face numerous challenges when transferring terabyte- and petabyte-scale data. This book follows a bottom-up approach by presenting an overview of Science DMZs and how they overcome the limitations of general-purpose networks. It also covers topics that have considerable impact on the performance of large data transfers at all layers: link layer (layer-2) and network layer (layer-3) topics such as maximum transmission unit (MTU), switch architectures, and router’s buffer size; transport layer (layer-4) topics including TCP features, congestion control algorithms for high-throughput high-latency networks, flow control, and pacing; applications (layer-5) used for large data transfers and for maintenance and operation of Science DMZs; and security considerations. Most chapters incorporate virtual laboratory experiments, which are conducted using network appliances running real protocol stacks. Students in computer science, information technology and similar programs, who are interested in learning fundamental concepts related to high-speed networks and corresponding implementations will find this book useful as a textbook. This book assumes minimal familiarity with networking, typically covered in an introductory networking course. It is appropriate for an upper-level undergraduate course and for a first-year graduate course. Industry professionals working in this field will also want to purchase this book.

Higher Education 4.0: The Digital Transformation of Classroom Lectures to Blended Learning
by Kevin Anthony Jones Sharma RavishankarThis book chronicles a 10-year introduction of blended learning into the delivery at a leading technological university, with a longstanding tradition of technology-enabled teaching and learning, and state-of-the-art infrastructure. Hence, both teachers and students were familiar with the idea of online courses. Despite this, the longitudinal experiment did not proceed as expected. Though few technical problems, it required behavioural changes from teachers and learners, thus unearthing a host of socio-technical issues, challenges, and conundrums. With the undercurrent of design ideals such as “tech for good”, any industrial sector must examine whether digital platforms are credible substitutes or at best complementary. In this era of Industry 4.0, higher education, like any other industry, should not be about the creative destruction of what we value in universities, but their digital transformation. The book concludes with an agenda for large, repeatable Randomised Controlled Trials (RCTs) to validate digital platforms that could fulfil the aspirations of the key stakeholder groups – students, faculty, and regulators as well as delving into the role of Massive Open Online Courses (MOOCs) as surrogates for “fees-free” higher education and whether the design of such a HiEd 4.0 platform is even a credible proposition. Specifically, the book examines the data-driven evidence within a design-based research methodology to present outcomes of two alternative instructional designs evaluated – traditional lecturing and blended learning. Based on the research findings and statistical analysis, it concludes that the inexorable shift to online delivery of education must be guided by informed educational management and innovation.
Higher Education Computer Science: A Manual of Practical Approaches
by Jenny Carter Michael O’Grady Clive RosenThe march towards on-line and blended teaching—present before the Covid-19 pandemic—has been accelerated by it, and there is no going back. Students and staff may object, but the economic drive towards “greater productivity” will inevitably result in less face-to-face (f2f) instruction. Therefore, it is incumbent for those delivering this precious, in-person resource to make maximum use of time…which raises the question, “how”?The second edition of Higher Education Computer Science offers some potential answers. It also addresses other questions, such as “why have f2f teaching at all?” “what is the purpose of f2f?” and “what is the appropriate balance between the two?” The first edition began to offer suggestions for optimising limited opportunities to get together with students. Aligned with that, this unique new volume examines how to use the technology available to maximum advantage: For example, resources such as Moocs and other on-line instructional materials can provide invaluable pedagogic support. In addition, the book addresses ‘problem-based learning,’ using robotics in the teaching of programming, and a multidisciplinary approach to data science. Although it includes a chapter on distance learning, there is greater emphasis placed on the soft, transferable skills and employability skills that are best delivered in person. Further, the work provides several examples of putting theory into practice when teaching computer science at both undergraduate and postgraduate levels. Written by experienced practitioners, each chapter tackles a particular teaching activity or topic within computing, presented in such a way that other practitioners can use. As such, this new volume will be an invaluable resource to those who want to protect and optimise in-person teaching.
Higher Education ICT Integration in Africa: Readiness, Implementation and Trajectory (ISSN)
by Ke Yu Reuben DlaminiThis multidisciplinary, edited volume examines higher educations’ ICT integration in Africa, contributing a new and inclusive change readiness framework to better understand how to manage ICT or other technological disruptions in resource-restrained contexts.Tackling ICT incorporation in HEIs from different levels, chapters document case studies from countries such as Uganda, South Africa, Rwanda, Eswatini and Zimbabwe to demonstrate both the complexity of integration but also the successes it has enabled and under which conditions. The cases included in this book also exhibit better incorporation of both change content and process, while some cases also make explicit reference to other technology adoption models. Ultimately, the book highlights conceptual and empirical research to inform practices and policy development in Africa, improving multi-level success or change readiness in ICT incorporation in HEIs in Africa.Addressing various gaps in existing literature and proposing innovative solutions like the multilevel change readiness model, this book will therefore be of interest to scholars, researchers and academics in the fields of higher education, ICT integration, and educational technology more broadly.The Open Access version of this book, available at http://www.taylorfrancis.com, has been made available under a Creative Commons Attribution-Non Commercial-No Derivatives (CC-BY-NC-ND) 4.0 license.

Higher Education and Technological Acceleration: The Disintegration of University Teaching and Research
by Ingrid M. HoofdThis book critically examines the relationship between new media technologies, research ethics, and pedagogical strategies within the contemporary university. It debates whether recent transformations of higher education, rather than an effect of neo-liberalization, are actually an outflow of the technological acceleration of the university's own contradictory ideals around knowledge and democracy. The book sets up this argument by likening the university to a "vision machine" which quest for total scientific and social transparency has recently caved in on itself, negatively affecting staff and student well-being. The book asserts that this situation reveals the essential tension at the heart of the university system, and explores the acceleration of this tension by analyzing a variety of teaching and research advances from Europe and Asia. Examining among other issues the call for creativity and critical thinking in the curriculum, the push for e-learning, and the advent of the digital humanities, this text offers a key analysis of the university's founding ideals and its constitutive relationship to technological acceleration.

Higher Education in the Digital Age
by William G. Bowen Kevin M. GuthrieTwo of the most visible and important trends in higher education today are its exploding costs and the rapid expansion of online learning. Could the growth in online courses slow the rising cost of college and help solve the crisis of affordability? In this short and incisive book, William G. Bowen, one of the foremost experts on the intersection of education and economics, explains why, despite his earlier skepticism, he now believes technology has the potential to help rein in costs without negatively affecting student learning. As a former president of Princeton University, an economist, and author of many books on education, including the acclaimed bestseller The Shape of the River, Bowen speaks with unique expertise on the subject. Surveying the dizzying array of new technology-based teaching and learning initiatives, including the highly publicized emergence of "massive open online courses" (MOOCs), Bowen argues that such technologies could transform traditional higher education--allowing it at last to curb rising costs by increasing productivity, while preserving quality and protecting core values. But the challenges, which are organizational and philosophical as much as technological, are daunting. They include providing hard evidence of whether online education is cost-effective in various settings, rethinking the governance and decision-making structures of higher education, and developing customizable technological platforms. Yet, Bowen remains optimistic that the potential payoff is great. Based on the 2012 Tanner Lectures on Human Values, delivered at Stanford University, the book includes responses from Stanford president John Hennessy, Harvard University psychologist Howard Gardner, Columbia University literature professor Andrew Delbanco, and Coursera cofounder Daphne Koller.
