Libri sul tema "Sex role – scandinavia"

Abstract A myth about the end of the world, the Ragnarök, was told among Viking Age Scandinavians. It is here reconsidered against a comparative background. The signs of the end, the final battle, and the destruction and renewal of the world are the main themes distinguished. Eddic poems, above all the Vǫluspá, and the Prose Edda of Snorri Sturluson provide the main sources. These are studied in detail and new interpretations are offered. The myth was handed down in a Christian medieval context and the problem of Christian influence is thoroughly discussed. Particular attention is given to the Old Norse homilies as instruments of conveying Christian teachings to both the elites and the common people. The comparative framework is set up by traditions on the end of the world in early Judaism, Christianity, Islam, the Graeco-Roman world, Celtic Europe, as well as ancient Iran and India. The geographical area covered by these traditions formed a network of cultural contacts providing possibilities of various influences. These texts are studied in their own right to avoid superficial paralleling. The analogies with Iranian traditions are striking and include the idea of the cosmic tree, the role of the number ‘nine’, and the myth of the heavenly warriors. The pre-Christian origins of the Scandinavian myth are emphasized, and an Indo-European background is suggested.

As more and more equipment incorporates advanced technologies, usability -- the ability of equipment to take advantage of users' skills and thereby to function effectively in the broad range of real work situations -- is becoming an essential component of equipment design. Usability: Turning Technologies into Tools collects six essays that herald a fundamental shift in the way industry and researchers think about usability. In this new, broader definition, usability no longer means safeguarding against human error, but rather enabling human beings to learn, to use, and to adapt the equipment to satisfy better the demands and contingencies of their work. Following an introduction that develops some core concepts of usability, the subsequent chapters: -- describe the role of usability in guiding one of Xerox's largest strategic initiatives -- analyze a Monsanto chemical plant where a study of worker's conversational patterns contributed to the design of a more effective system of controls -- present an empirical study of equipment design practices in U.S. industry which contrasts technology-centered and skill-based design approaches -- summarize recent Scandinavian experiences with user participation in design, with specific reference to the DEMOS and UTOPIA projects -- analyze European experiences that suggest five key criteria for effective human-centered design of advanced manufacturing technology --offer an insightful discussion of the powerful, often hidden human and organizational resources that conventional design processes overlook. Today, three quarters of all advanced technology implementations in manufacturing fail to achieve their performance goals because of inadequate usability. By viewing the human being as a mechanistic system component, and not a particularly reliable one, the traditional "human factors" model of usability virtually ensures that the uniquely human qualities -- experience, adaptation, innovation -- will be neglected, and therefore that new technologies will realize little of their true potential. Usability: Turning Technologies into Tools answers the need for better usability criteria and more effective design and usability assurance processes. In so doing, it leads the way to making a new, broader concept of usability central to design. Its chapters will be of interest to managers and professionals in computer systems, manufacturing engineering, industrial design, and human factors, as well as researchers in disciplines such as computer science, engineering, design studies, sociology, organizational behavior and human resource management, industrial relations, education, and business strategy.
