What makes this book different from others on database design? Many resources on design practice do little to explain the underlying theory, and books on design theory are aimed primarily at theoreticians. In this book, renowned expert Chris Date bridges the gap by introducing design theory in ways practitioners can understand—drawing on lessons learned over four decades of experience to demonstrate why proper database design is so critical in the first place.Every chapter includes a set of exercises that show how to apply the theoretical ideas in practice, provide additional information, or ask you to prove some simple theoretical result. If you’re a database professional familiar with the relational model, and have more than a passing interest in database design, this book is for you.Questions this book answers include:Why is Heath’s Theorem so important?What is The Principle of Orthogonal Design?What makes some JDs reducible and others irreducible?Why does dependency preservation matter?Should data redundancy always be avoided? Can it be?Databases often stay in production for decades, and careful design is critical for avoiding subtle errors and processing problems over time. If they’re badly designed, the negative impacts can be incredibly widespread. This gentle introduction shows you how to use important theoretical results to create good database designs.

The central argument of On Being Normal and Other Disorders is that psychic identity is acquired through one's primary intersubjective relationships. Thus, the diagnosis of potential pathologies must also be founded on this relation. Given that the efficacy of all forms of treatment depends upon the therapeutic relation, a diagnostic of this sort has wide-ranging applications. The author's critical evaluation of the contemporary DSM-diagnostic shows that the lack of reference to and governing metapsychology impinges on the therapeutic value of the DSM categories. In response to this problem, the author sketches out the foundations of such a metapsychology by combining a Freudo-Lacanian approach with contemporary empirical research. Close attention is paid to the processes of identity acquisition to show how the self and the Other are not two separate entities. Rather, subject formation is seen as a process in which both the subject's and the Other's identity, as well as the relationship between them, comes into being.

Asperger's Syndrome, often characterized as a form of "high-functioning autism," is a poorly defined and little-understood neurological disorder. The people who suffer from the condition are usually highly intelligent, and as often as not capable of extraordinary feats of memory, calculation, and musicianship. In this wide-ranging report on Asperger's, Lawrence Osborne introduces us to those who suffer from the syndrome and to those who care for them as patients and as family. And, more importantly, he speculates on how, with our need to medicate and categorize every conceivable mental state, we are perhaps adding to their isolation, their sense of alienation from the "normal." -This is a book about the condition, and the culture surrounding Asperger's Syndrome as opposed to a guide about how to care for your child with Aspergers. -Examines American culture and the positive and negative perspectives on the condition. Some parents hope their child will be the next Glenn Gould or Bill Gates, others worry that their child is abnormal and overreact.

In Glen Canyon waters rose, inundating petroglyphs and creating Lake Powell. Now the Colorado River basin is experiencing the longest dry spell in modern history—one that shows alarming signs of becoming the new normal.   In A New Form of Beauty photographer Peter Goin and writer Peter Friederici tackle science from the viewpoint of art, creating a lyrical exploration in words and photographs, setting Glen Canyon and Lake Powell as the quintessential example of the challenges of perceiving place in a new era of radical change. Through evocative photography and extensive reporting, the two document their visits to the canyon country over a span of many years. By motorboat and kayak, they have ventured into remote corners of the once-huge reservoir to pursue profound questions: What is this place? How do we see it? What will it become?   Goin’s full-color photographs are organized in three galleries—Flora and Fauna, Artifacts, and Low Water—interspersed with three essays by Friederici, and an epilogue gallery on Fire. The book includes two foldout photographs, which allow readers to fully see Lake Powell at high water and low water points Contemplating humanity’s role in the world it is creating, Goin and Friederici ask if the uncertainties inherent in Glen Canyon herald an unpredictable new future for every place. They challenge us to question how we look at the world, how we live in it, and what the future will be.
