In a land of eagle-riding knights, bloodthirsty beasts, and a ruthless prince, no border is safe for long. And as smoke billows from the only blockade standing between the great city of Korindelf and certain doom, young Morlen races to escape the inevitable siege. Thrust from the chaos with thousands of snapping jaws on his trail, he discovers that the abilities he's buried all his life are awakening-and it could not have happened at a worse time. War has come, and he doesn't dare rely on his untested talents after stealing the coveted Goldshard, which makes strength and invincibility just a panicked whisper away. His dependency on it carries him through many dangers, until it becomes an enemy far worse than those he must fight hand-to-hand. And the allies he meets on his quest are just as troubled: a legendary warrior too afraid to leave his sheltered paradise, a wizard tormented by his past, and a disgraced king who has lost any hope of saving his people. A FACET FOR THE GEM brings Morlen from distant kingdoms to sprawling airborne battles, into the fiery breath of a stony dragon and side-by-side with a lady knight who is the last person in need of rescue. Follow him as his epic adventures culminate in a final showdown against swords, fangs, and greatest of all: his own fear.

The Discipline of Organizing: Professional Edition by Robert J. Glushko Pdf
Note about this ebook: This ebook exploits many advanced capabilities with images, hypertext, and interactivity and is optimized for EPUB3-compliant book readers, especially Apple's iBooks and browser plugins. These features may not work on all ebook readers. We organize things. We organize information, information about things, and information about information. Organizing is a fundamental issue in many professional fields, but these fields have only limited agreement in how they approach problems of organizing and in what they seek as their solutions. The Discipline of Organizing synthesizes insights from library science, information science, computer science, cognitive science, systems analysis, business, and other disciplines to create an Organizing System for understanding organizing. This framework is robust and forward-looking, enabling effective sharing of insights and design patterns between disciplines that weren’t possible before. The Professional Edition includes new and revised content about the active resources of the "Internet of Things," and how the field of Information Architecture can be viewed as a subset of the discipline of organizing. You’ll find: 600 tagged endnotes that connect to one or more of the contributing disciplines Nearly 60 new pictures and illustrations Links to cross-references and external citations Interactive study guides to test on key points The Professional Edition is ideal for practitioners and as a primary or supplemental text for graduate courses on information organization, content and knowledge management, and digital collections. FOR INSTRUCTORS: Supplemental materials (lecture notes, assignments, exams, etc.) are available at http://disciplineoforganizing.org. FOR STUDENTS: Make sure this is the edition you want to buy. There's a newer one and maybe your instructor has adopted that one instead.
The Complexity of Bird Behaviour by Paul M. W. Hackett Pdf
This book presents the facet theoretical framework as a tool for facilitating the conception of complex animal behaviour research and the design of research procedures through employing mapping sentences. Using the facet theoretical framework, this book takes a holistic view of bird behaviour. Components of bird behavior are identified and then reassembled to facilitate an understanding of the behaviour in the context of its natural occurrence. This provides new insight on both the parts of the behaviour and how these interact as a whole. The multi-faceted approach to designing, evaluating and understanding bird behavior presented offers a template that is adaptable for investigating a wide variety of avian species and different forms of behaviour. Behavioural biologists, animal and comparative psychologists, other natural and behavioural scientists, as well as students of these disciplines will find this book to be an interesting and enlightening read.
