This volume was primarily intended to present selected papers from the workshop on Theory and Applications of Nested Relations and Complex Objects, held in Darmstadt, FRG, from April 6-8, 1987. Other papers were solicited in order to provide a picture of the field as general as possible. Research on nested relations and complex objects originates in the late seventies. The motivation was to obtain data models and systems which would provide support for so-called complex objects or molecular structures, i.e., for hierarchically organized data, thereby overcoming severe shortcomings of the relational model. This theme of research is now maturing. Systems based on those ideas are beginning to be available. Languages of various natures (algebras, calculi, graphical, logic-oriented) have been designed and a theory is slowly emerging. Finally, new developments in database technology and research are incorporating features of models involving complex objects. A variety of approaches is represented in this volume. The first three papers give overviews of major pioneering implementation efforts. The fourth paper is devoted to the important issue of implementation of storage structures. The next three papers propose excursions in the foundations of nested relations and complex objects. The following six contributions are all devoted to modeling of complex objects. The area of database design is represented by the last four papers.
Researchers studying the health of migrants frequently use standard quantitative instruments to assess psychological constructs. Such instruments are often validated only in the respective source population of migrants. For example, when studying Turkish migrants in Germany, instruments validated in Turkey are applied. However, considerable differences in culture and language may have developed between migrants and their source population. These differences limit the validity and reliability of quantitative instruments, a problem that is often overlooked. Using the example of the Revised Illness Perception Questionnaire (IPQ-R), the authors demonstrate that instruments known to be valid and reliable in source populations may lead to biased results when applied to migrant populations.
Avian Surgical Anatomy: Thoracic and Pelvic Limbs by Orosz, Ensley and Haynes, was published in 1992 and has served as a standard guide for those performing orthopedic surgery on birds. That foundational work is out of print but the need for a concise source of avian surgical anatomy has not changed. Our objective in this edition has been to recapture the musculoskeletal anatomy of the original work and to expand the scope to include comprehensive coverage for the clinical management of common fractures of the long bones of birds, primarily raptors. The procedures described have been honed over two decades of development and refinement by clinicians at the Raptor Center at the University of Minnesota. In addition, we have included details of the vascular anatomy of the limbs, further informing the surgeon and clinician. The class Aves includes thousands of species with countless anatomic variations. Although it is impractical to represent every species, birds commonly encountered in private practice and rehabilitation medicine including poultry, pigeons, parrots and birds of prey were chosen for this book. Details of the vascular anatomy of the limbs were obtained by high resolution digital computed tomography imaging of the appendicular skeleton of several diverse bird species. These images provide a unique comparative aspect that clinicians will find useful in conducting surgical procedures. This new information is intended to help the reader better understand skeletal and vascular anatomy, and thus improve interpretation, reporting of findings, treatment and teaching. This new information is intended to help the reader better understand relationships between musculoskeletal and vascular anatomy, helping the surgeon preserve vasculature during complex orthopedic procedures. It is our hope that it will enrich the interpretation, reporting of findings, development of treatment methods and the teaching of management procedures for orthopedic issues in birds. Since publication of the first edition, numerous advances have been made and published relative to avian orthopedics. In this edition, you will find comprehensive discussion of orthopedic conditions, and clinical management that represents best treatment options and current practices. The title of the book has been changed to reflect inclusion of that information. As our knowledge of avian anatomy, health and disease progresses, so does the need for improved resources that convey this valuable information. Over time the information contained herein will also need to be expanded and updated. The authors humbly submit this work to the veterinary and scientific community for review and scrutiny. We hope that it will contribute to the betterment of avian care.
One of the highest-paid studio contract directors of his time, George Cukor was nominated five times for an Academy Award as Best Director. In publicity and mystique he was dubbed the “women’s director” for guiding the most sensitive leading ladies to immortal performances, including Greta Garbo, Ingrid Bergman, Judy Garland, and—in ten films, among them The Philadelphia Story and Adam’s Rib—his lifelong friend and collaborator Katharine Hepburn. But behind the “women’s director” label lurked the open secret that set Cukor apart from a generally macho fraternity of directors: he was a homosexual, a rarity among the top echelon. Patrick McGilligan’s biography reveals how Cukor persevered within a system fraught with bigotry while becoming one of Hollywood’s consummate filmmakers.
The main underlining conviction, throughout the book, is the importance of dynamical and systemic approaches to innovation policies. The first part of the book provides the theoretical background for the subsequent more empirical contributions. In the second part, a series of three papers analyse each the development or diffusion of a specific technology developed in the frame of a procurement policy. They explain the success of mission-oriented policies (the development of digital switching systems in the telecom sector, the development of high-speed trains in Germany and the diffusion of military technologies). The three papers contained in the third part explore the impact of incentive tools (R&D tax credits, R&D cooperative agreements and university-industry relations) on the innovation potentialities of firms and of economic systems (regions). The chapters in the last part of the book are all based around the question of how is it possible to design an innovation policy, applicable throughout Europe, bearing in mind the diversity of innovation behaviours and strategies.
This book represents a classic compilation of current knowledge about mouse development and its correlates to research in cell biology, molecular biology, genetics, and neuroscience. Emphasis is placed on the research strategy, experimental design, and critical analysis of the data, disguishing this from other books that only focus on protocols for mouse developmental research. Selected chapters are indexed to electronic databases such as GeneBank, GenBank, Electronic Mouse Atlas, and Transgenic/Knockout, further increasing the utility of this book as a reference. *Broad-based overview of mouse development from fundamental to specialist levels*Extensive coverage of a wide range of developmental mutations of the mouse*Excellent benchmark illustrations of brain, craniofacial, gut and heart development*In-depth experiment-based assessment of concepts in mammalian development*Focus on models of specific relevance to human development*Comprehensive reference to key literature and electronic databases related to mouse development*High-quality full-color production
This book, first published in 1993, examines in detail the bureaucratic and political manoeuvring surrounding the enactment of banking and monetary reforms in the 1930s. Although banking reform influenced the politics of both the Hoover and Roosevelt presidencies, most surveys devote only a few pages to monetary disturbances and the reforms passed as a result.
