What happens in a tradition that links citizenship with soldiering when women become citizens? Citizen Soldiers and Manly Warriors: Military Service and Gender in the Civic Republican Tradition provides an in-depth analysis of the theory and practice of the citizen-soldier in historical context. Using a postmodern feminist lens, Snyder reveals that within the citizen-soldier tradition, citizenship and masculinity are simultaneously constituted through engagement in civic and martial practices. Seeking to sever the connection between masculinity and citizenship, Snyder calls for women to make 'gender trouble' by engaging in the practices traditionally constitutive of masculine republican citizenship. However, in order to reconstitute the Citizen-Soldier traditionDthe only tradition we have that holds the military up to democratic standardsDwe must not only 'trouble' but also reconfigure our understandings of gender and citizenship. Thus gender parity in the American military is not enough. We must also change the type of masculinity produced by the military, reintroduce the military to its civic purposes, expand the 'citizenship of civic practices' to include other non-martial forms of service, and give citizens a greater role in political decision making.
This classic work has helped shape the field of international relations and especially influenced scholars interested in how foreign policy is made. At a time when conventional wisdom and traditional approaches are being questioned, and when there is increased interest in the importance of process, the insights of Snyder, Bruck and Sapin have continuing and increased relevance. Prescient in its focus on the effects on foreign policy of individuals and their preconceptions, organizations and their procedures, and cultures and their values, "Foreign Policy Decision-Making" is of continued relevance for anyone seeking to understand the ways foreign policy is made. Their seminal framework is here complemented by two new chapters examining its influence on generations of scholars, the current state of the field, and areas for future research.
The latest edition of the authoritative reference to HPLC High-performance liquid chromatography (HPLC) is today the leading technique for chemical analysis and related applications, with an ability to separate, analyze, and/or purify virtually any sample. Snyder and Kirkland's Introduction to Modern Liquid Chromatography has long represented the premier reference to HPLC. This Third Edition, with John Dolan as added coauthor, addresses important improvements in columns and equipment, as well as major advances in our understanding of HPLC separation, our ability to solve problems that were troublesome in the past, and the application of HPLC for new kinds of samples. This carefully considered Third Edition maintains the strengths of the previous edition while significantly modifying its organization in light of recent research and experience. The text begins by introducing the reader to HPLC, its use in relation to other modern separation techniques, and its history, then leads into such specific topics as: The basis of HPLC separation and the general effects of different experimental conditions Equipment and detection The column—the "heart" of the HPLC system Reversed-phase separation, normal-phase chromatography, gradient elution, two-dimensional separation, and other techniques Computer simulation, qualitative and quantitative analysis, and method validation and quality control The separation of large molecules, including both biological and synthetic polymers Chiral separations, preparative separations, and sample preparation Systematic development of HPLC separations—new to this edition Troubleshooting tricks, techniques, and case studies for both equipment and chromatograms Designed to fulfill the needs of the full range of HPLC users, from novices to experts, Introduction to Modern Liquid Chromatography, Third Edition offers the most up-to-date, comprehensive, and accessible survey of HPLC methods and applications available.
Gradient elution demystified Of the various ways in which chromatography is applied today, few have been as misunderstood as the technique of gradient elution, which presents many challenges compared to isocratic separation. When properly explained, however, gradient elution can be less difficult to understand and much easier to use than often assumed. Written by two well-known authorities in liquid chromatography, High-Performance Gradient Elution: The Practical Application of the Linear-Solvent-Strength Model takes the mystery out of the practice of gradient elution and helps remove barriers to the practical application of this important separation technique. The book presents a systematic approach to the current understanding of gradient elution, describing theory, methodology, and applications across many of the fields that use liquid chromatography as a primary analytical tool. This up-to-date, practical, and comprehensive treatment of gradient elution: * Provides specific, step-by-step recommendations for developing a gradient separation for any sample * Describes the best approach for troubleshooting problems with gradient methods * Guides the reader on the equipment used for gradient elution * Lists which conditions should be varied first during method development, and explains how to interpret scouting gradients * Explains how to avoid problems in transferring gradient methods With a focus on the use of linear solvent strength (LSS) theory for predicting gradient LC behavior and separations by reversed-phase HPLC, High-Performance Gradient Elution gives every chromatographer access to this useful tool.
In the 1700s, Amsterdam was just a small trading village in upstate New York. Utilizing its superior location astride critical waterways, the village grew during the westward expansion of the early 1800s to become an industrial powerhouse. By the 20th century, Amsterdam had become America's foremost rug-making center, nicknamed the "Carpet City," and the seventh largest city in New York. Waves of Dutch, German, Irish, Italian, and eastern European immigrants were drawn to the city for work. Some became mill workers while others became millionaires. The vintage postcards in Amsterdam tell the story of an American dream created, lost, and still pursued on what was once America's frontier.
Over the last 15 years, high-performance liquid chromatogra phy (LC) has made the transition from an instrument used only by experts in research labs to a tool used for routine applications by relatively unskilled workers. With this transition have come in instrumentation and column technology. In major advances the past, the operator had to be a jack-of-all-trades, with a screw driver, soldering iron, and various wrenches as constant compan ions in the LC lab. Today, many instruments contain micropro cessors as powerful as those of mainframe computers of earlier days. With this technology has come a variety of self-diagnostic tools that allow the LC system to locate many of its own prob lems. Traditionally, well-honed LC troubleshooting skills have been a result of years of work at the bench. Today the LC system itself often can do a better job of troubleshooting than the operator can. Yet many of the problems of the past are still the major problems of today: air bubbles, check valves, detector lamps, and, of course, problems with the separation. An added pressure on the operator of today's LC system is that of productivity-the lab often cannot afford unnecessary downtime. This means that the operator has to be a troubleshooting expert, or has to have that expertise at his or her fingertips. The present book was written to provide this expertise in an easy-to-use format for users at all levels of experience.
While White parents raising Black children has become increasingly salient in the last 20?30 years, the experience of those who grow up in these cross?racial families is much more complicated. Indeed, much of the adoption studies literature has privileged White parent voices, further silencing crossracially raised Black?identified children. “Is That Your Mom?” challenges the dominant narrative that love trumps race (and racism) in family dynamics, and reasserts the need for critical voices of those most impacted by being cross?racially raised: the very people who face extreme racism that is both similar to, and uniquely different from, that faced by people of color more broadly. “Is That Your Mom?” centers the voices of Cross Racially Raised individuals of the African Diaspora to illustrate that racial socialization is a process in which individuals have agency in their racial development. In this book, Cross Racially Raised adults, both those who were adopted and those who were raised in cross?racial birth families, share their stories regarding experiences with racism in the following three ways: (1) encounters with racism within and beyond educational settings, (2) perceptions of parents or guardians’ efforts toward racial socialization, and (3) strategies used to navigate racially hostile environments (which sometimes are the families themselves). The voices of the individuals in this book illuminate a deeper conceptual understanding of how racial socialization practices are linked with one’s ability to cope with racism and ways of addressing racism, particularly among those families that contradict monoracial assumptions of racial socialization processes. The book concludes with a discussion of how schools, educators, and parents can help Cross Racially Raised children and youth develop skills necessary to cope and remain resilient in the face of racism, particularly if the immediate family is not offering those supports.

Larvatus prodeo," announced René Descartes at the beginning of the seventeenth century: "I come forward, masked." Deliberately disguising or silencing their most intimate thoughts and emotions, many early modern Europeans besides Descartes-princes, courtiers, aristocrats and commoners alike-chose to practice the shadowy art of dissimulation. For men and women who could not risk revealing their inner lives to those around them, this art of incommunicativity was crucial, both personally and politically. Many writers and intellectuals sought to explain, expose, justify, or condemn the emergence of this new culture of secrecy, and from Naples to the Netherlands controversy swirled for two centuries around the powers and limits of dissimulation, whether in affairs of state or affairs of the heart. This beautifully written work crisscrosses Europe, with a special focus on Italy, to explore attitudes toward the art of dissimulation in the sixteenth and seventeenth centuries. Discussing many canonical and lesser-known works, Jon R. Snyder examines the treatment of dissimulation in early modern treatises and writings on the court, civility, moral philosophy, political theory, and in the visual arts.
The 'rediscovery' in sixteenth-century Italy of Aristotle's Poetics marks a crucial moment in the development of Western thought about literature, for the flood of new and controversial works that accompanied this event laid the foundations of modern literary criticism and theory. This is a study of the main literary theories of the late Italian Renaissance that seek to define a poetics of dialogue. The author contends that dialogue - among the most popular of all prose forms in Italy to develop a new theory of literature, because it seems to subvert the conventional Renaissance understanding of what is 'literary' and what is not. With its close ties to dialectic and to Platonic philosophy on the one hand, and its equally vital links to imaginative fiction on the other, dialogue in the Renaissance stands at the crossroads of the discourses of cognition and fiction. Writing the Scene of Speaking examines the different solutions offered by sixteenth-century Italian theorists to the problem posed by the hybrid textuality of dialogue, and sets them in the context of a culture in a dramatic state of transition.

The story of the Cheasapeake and Ohio Canal during the Civil War is a tale of the company's struggle to operate a transportation line in one of the of the country's major theaters of war. The canal's position along Maryland's southern border with Virginia left it in a unique position to experience the war first-hand, and indeed records show that the company was drawn into the conflict within days after the surrender of Fort Sumter ... An examination of the canal company during this period allows readers to see how the company responded to the many threats it faced, including the seizure and destruction of its property, military interference in its operations, and a chronic shortage of operating funds. Existing records are such that on some occasions the reader can determine how the canal company responded to a challenge -- such as a Confederate invasion -- on nearly a day-to-day basis, providing a glimpse into the operations of a company during the Civil War that few other accounts provide"--P. xv.
