This book uses case studies to show how and why eight social service organizations adopted computers. Computerized information systems can be destructive or constructive for organizations and staff. However, the impact of a system cannot be predicted from its logical design alone: one must analyze how well the design fits the needs, interests, and existing practices of those who are likely to use it.
Plagues in World History provides a concise, comparative world history of catastrophic infectious diseases, including plague, smallpox, tuberculosis, cholera, influenza, and AIDS. Geographically, these diseases have spread across the entire globe; temporally, they stretch from the sixth century to the present. John Aberth considers not only the varied impact that disease has had upon human history but also the many ways in which people have been able to influence diseases simply through their cultural attitudes toward them. The author argues that the ability of humans to alter disease, even without the modern wonders of antibiotic drugs and other medical treatments, is an even more crucial lesson to learn now that AIDS, swine flu, multidrug-resistant tuberculosis, and other seemingly incurable illnesses have raged worldwide. Aberth's comparative analysis of how different societies have responded in the past to disease illuminates what cultural approaches have been and may continue to be most effective in combating the plagues of today.
The Georgian period 1714 to 1837 was a key stage in our modern history so some understanding of it is essential for family historians who want to push their research back into the eighteenth century and beyond, and John Wintrip's handbook is an invaluable introduction to it. In a sequence of concise, insightful chapters he focuses on those aspects of the period that are particularly relevant to genealogical research and he presents a detailed guide to the variety of sources that readers can consult as they pursue their research.While fewer sources are available than for more recent history, obstacles in the way of further research can often be overcome through knowledge of a wide range of sources and a greater understanding the historical context, together with the use of sound research techniques. So the author provides not only a historical overview of relevant topics but he also describes the records of the period in detail.This expert guide to researching the Georgians will open up the field for experienced researchers and for newcomers alike.
Lecturers, request your electronic inspection copy This sharp, innovative book champions the rising significance of ethnographic research on the use of digital resources around the world. It contextualises digital and pre-digital ethnographic research and demonstrates how the methodological, practical and theoretical dimensions are increasingly intertwined. Digital ethnography is central to our understanding of the social world; it can shape methodology and methods, and provides the technological tools needed to research society. The authoritative team of authors clearly set out how to research localities, objects and events as well as providing insights into exploring individuals’ or communities’ lived experiences, practices and relationships. The book: Defines a series of central concepts in this new branch of social and cultural research Challenges existing conceptual and analytical categories Showcases new and innovative methods Theorises the digital world in new ways Encourages us to rethink pre-digital practices, media and environments This is the ideal introduction for anyone intending to conduct ethnographic research in today’s digital society.
The most up-to-date coverage of welding metallurgy aspects and weldability issues associated with Ni-base alloys Welding Metallurgy and Weldability of Nickel-Base Alloys describes the fundamental metallurgical principles that control the microstructure and properties of welded Ni-base alloys. It serves as a practical how-to guide that enables engineers to select the proper alloys, filler metals, heat treatments, and welding conditions to ensure that failures are avoided during fabrication and service. Chapter coverage includes: Alloying additions, phase diagrams, and phase stability Solid-solution strengthened Ni-base alloys Precipitation strengthened Ni-base alloys Oxide dispersion strengthened alloys and nickel aluminides Repair welding of Ni-base alloys Dissimilar welding Weldability testing High-chromium alloys used in nuclear power applications With its excellent balance between the fundamentals and practical problem solving, the book serves as an ideal reference for scientists, engineers, and technicians, as well as a textbook for undergraduate and graduate courses in welding metallurgy.
