Digital Difference

A sense of disquietude seems ever present when discussing new digital practices. The transformations incurred through these can be profound, troublesome in nature and far-reaching. Moral panics remain readily available. Discussing the manner in which digital culture within education might differ from its ‘analogue’ predecessors incurs the risk of resorting to increasingly roadworn meta¬phors of new frontiers, ‘cyber’ domains, inter-generational conflicts and, inevitably, the futurist utopias and dystopias characterised by Western media throughout the twentieth century. These imaginings now seem to belong to an earlier era of internet thinking. We are freer, over two decades on, to re-evaluate digital difference from new perspectives. Are digital learning environments now orthodox, or do the rapidly emerging technologies hold a new promise and a new arena of difference for pedagogical practice? What are the points of rift, and the points of continuity, between virtual learning spaces and their equivalents in the real? What qualities of difference should concern us now? The writings in this collection from three continents reflect a complex embrace of culture, power and technology. Topics range from social questions of consumption, speed, uncertainty, and risk to individual issues of identity, selfhood and desire. Ethical issues arise, involving equity and authority, as well as structural questions of order and ambiguity. From these themes emerges an engaging agenda for future educational research and practice in higher education over the coming decade. The book will interest teachers, practitioners and managers from all disciplines, as well as educational researchers.

W. Russell Neuman examines how the transition from the industrial-era media of one-way publishing and broadcasting to the two-way digital era of online search and social media has affected the dynamics of public life. The issues range from propaganda studies and Big Brother to information overload and Internet network neutrality.

Accurately differentiate between errors that are related to second-language influence or are due to a communication disorder. Is your student having difficulty because they have an impairment or because they are learning a second language? Improve instructional targets for culturally and linguistically diverse students in the general education classroom as well as make gains and improve referrals for special education. The framework used in this book makes it easy for any education professional to distinguish between language differences and language disorders regardless of your own language background.

A case-based reference for digital mammography Practical Digital Mammography provides breast imagers with a systematic, problem-solving approach to detecting and assessing the most subtle signs of breast cancer malignancies. The book opens with concise coverage of the fundamentals, including physics, equipment, and normal anatomy. Separate chapters provide straightforward descriptions and clear illustrations of the digital mammographic characteristics of benign and malignant calcifications, masses, asymmetry, and architectural distortion. The author presents the clinical workup of the most difficult mammographic findings and provides recommendations about the optimizing the techniques for localizing each finding. Features: 103 illustrated cases help readers gain a firm understanding of how to interpret digital mammographic findings Summary tables provide succinct descriptions of digital mammographic findings correlated to the American College of Radiology's BI-RAD assessment categories Practical discussion of the advantages of digital mammography over screen-film techniques and equipment enables readers to compare technologies and systems "Pearls and Pitfalls" review key points and considerations with its broad coverage and emphasis on clinical techniques, this book is indispensable for radiologists, residents, and technologists confronting the challenges of a digital mammographic imaging center.
