Abstract

The essays in this volume of the Journal continue its proud tradition of presenting cutting-edge research with a wide chronological and geographical, range, from eleventh-century Georgia (David IV's use of the methods described in De velitatione bellica) to fifteenth-century England and France (a detailed analysis of the use of the under-appreciated lancegay and similar weapons). Iberia and the Empire are also addressed, with a study of Aragonese leaders in the War of the Two Pedros, a discussion of Prince Ferdinand's battle-seeking strategy prior to the battle of Toro in 1476, and an analysis and transcription of a newly-discovered Habsburg battle plan of the early sixteenth century, drawn up for the war against Venice. The volume also embraces different approaches, from cultural-intellectual history (the afterlife of the medieval Christian Warrior), to experimental archaeology (the mechanics of raising trebuchets), to comparison of 'the face of battle' in a medieval illuminated manuscript with its depiction in modern films, to archivally-based administrative history (recruitment among the sub-gentry for Edward I's armies).

Abstract

While some books present “ideal” ethnographic field methods, Inside Ethnography shares the realities of fieldwork in action. With a focus on strategies employed with populations at society’s margins, twenty-one contemporary ethnographers examine their cutting-edge work with honesty and introspection, drawing readers into the field to reveal the challenges they have faced. Representing disciplinary approaches from criminology, sociology, anthropology, public health, business, and social work, and designed explicitly for courses on ethnographic and qualitative methods, crime, deviance, drugs, and urban sociology, the authors portray an evolving methodology that adapts to the conditions of the field while tackling emerging controversies with perceptive sensitivity. Their judicious advice on how to avoid pitfalls and remedy missteps provides unusual insights for practitioners, academics, and undergraduate and graduate students.

Abstract

"In 1969, Princeton physicist Gerard O'Neill began looking outward to space colonies as the new frontier for humanity's expansion. A decade later, Eric Drexler, an MIT-trained engineer, turned his attention to the molecular world as the place where society's future needs could be met using self-replicating nanoscale machines. These modern utopians predicted that their technologies could transform society as humans mastered the ability to create new worlds, undertook atomic-scale engineering, and, if truly successful, overcame their own biological limits. The Visioneers tells the story of how these scientists and the communities they fostered imagined, designed, and popularized speculative technologies such as space colonies and nanotechnologies. Patrick McCray traces how these visioneers blended countercultural ideals with hard science, entrepreneurship, libertarianism, and unbridled optimism about the future. He shows how they built networks that communicated their ideas to writers, politicians, and corporate leaders. But the visioneers were not immune to failure--or to the lures of profit, celebrity, and hype. O'Neill and Drexler faced difficulty funding their work and overcoming colleagues' skepticism, and saw their ideas co-opted and transformed by Timothy Leary, the scriptwriters of Star Trek, and many others. Ultimately, both men struggled to overcome stigma and ostracism as they tried to unshackle their visioneering from pejorative labels like "fringe" and "pseudoscience." The Visioneers provides a balanced look at the successes and pitfalls they encountered. The book exposes the dangers of promotion--oversimplification, misuse, and misunderstanding--that can plague exploratory science. But above all, it highlights the importance of radical new ideas that inspire us to support cutting-edge research into tomorrow's technologies"--

Abstract

This specialist edition features key innovations in the science and engineering of new grinding processes, abrasives, tools, machines, and systems for a range of important industrial applications. Topics written by invited, internationally recognized authors review the advances and present results of research over a range of well-known grinding processes. A significant introductory review chapter explores innovations to achieve high productivity and very high precision in grinding. The reviewed applications range from grinding systems for very large lenses and reflectors, through to medium size grinding machine processes, and down to grinding very small components used in MEMS . Early research chapters explore the influence of grinding wheel topography on surface integrity and wheel wear. A novel chapter on abrasive processes also addresses the finishing of parts produced by additive manufacturing through mass finishing. Materials to be ground range from conventional engineering steels to aerospace materials, ceramics, and composites. The research findings highlight important new results for avoiding material sub-surface damage. The papers compiled in this book include references to many source publications which will be found invaluable for further research, such as new features introduced into control systems to improve process efficiency. The papers also reflect significant improvements and research findings relating to many aspects of grinding processes, including machines, materials, abrasives, wheel preparation, coolants, lubricants, and fluid delivery. Finally, a definitive chapter summarizes the optimal settings for high precision and the achievement of centerless grinding stability.

Abstract

Recent years have witnessed an upsurge in global health emergencies-from SARS to pandemic influenza to Ebola to Zika. Each of these occurrences has sparked calls for improved health preparedness. In Unprepared, Andrew Lakoff follows the history of health preparedness from its beginnings in 1950s Cold War civil defense to the early twenty-first century, when international health authorities carved out a global space for governing potential outbreaks. Alert systems and trigger devices now link health authorities, government officials, and vaccine manufacturers, all of whom are concerned with the possibility of a global pandemic. Funds have been devoted to cutting-edge research on pathogenic organisms, and a system of post hoc diagnosis analyzes sites of failed preparedness to find new targets for improvement. Yet, despite all these developments, the project of global health security continues to be unsettled by the prospect of surprise.

Abstract

Metrology is the science of measurement, which can be divided into three overlapping activities: (1) the definition of units of measurement, (2) the realization of units of measurement, and (3) the traceability of measurement units. Manufacturing metrology originally implicates the measurement of components and inputs for a manufacturing process to assure they are within specification requirements. It can also be extended to indicate the performance measurement of manufacturing equipment. This Special Issue covers papers revealing novel measurement methodologies and instrumentations for manufacturing metrology from the conventional industry to the frontier of the advanced hi-tech industry. Twenty-five papers are included in this Special Issue. These published papers can be categorized into four main groups, as follows: Length measurement: covering new designs, from micro/nanogap measurement with laser triangulation sensors and laser interferometers to very-long-distance, newly developed mode-locked femtosecond lasers. Surface profile and form measurements: covering technologies with new confocal sensors and imagine sensors: in situ and on-machine measurements. Angle measurements: these include a new 2D precision level design, a review of angle measurement with mode-locked femtosecond lasers, and multi-axis machine tool squareness measurement. Other laboratory systems: these include a water cooling temperature control system and a computer-aided inspection framework for CMM performance evaluation.
