In 1950, when he commissioned the first edition of The Armed Forces Officer, Secretary of Defense George C. Marshall told its author, S.L.A. Marshall, that "American military officers, of whatever service, should share common ground ethically and morally." In this new edition, the authors methodically explore that common ground, reflecting on the basics of the Profession of Arms, and the officer's special place and distinctive obligations within that profession and especially to the Constitution.
The Noncommissioned Officer and Petty Officer BACKBONE of the Armed Forces. Introduction The Backbone of the Armed Forces To be a member of the United States Armed Forces--to wear the uniform of the Nation and the stripes, chevrons, or anchors of the military Services--is to continue a legacy of service, honor, and patriotism that transcends generations. Answering the call to serve is to join the long line of selfless patriots who make up the Profession of Arms. This profession does not belong solely to the United States. It stretches across borders and time to encompass a culture of service, expertise, and, in most cases, patriotism. Today, the Nation's young men and women voluntarily take an oath to support and defend the Constitution of the United States and fall into formation with other proud and determined individuals who have answered the call to defend freedom. This splendid legacy, forged in crisis and enriched during times of peace, is deeply rooted in a time-tested warrior ethos. It is inspired by the notion of contributing to something larger, deeper, and more profound than one's own self. Notice: This is a printed Paperback version of the "The Noncommissioned Officer and Petty Officer BACKBONE of the Armed Forces". Full version, All Chapters included. This publication is available (Electronic version) in the official website of the National Defense University (NDU). This document is properly formatted and printed as a perfect sized copy 6x9".
This updated and reorganized fourth edition of Software Testing: A Craftsman's Approach applies the strong mathematics content of previous editions to a coherent treatment of Model-Based Testing for both code-based (structural) and specification-based (functional) testing. These techniques are extended from the usual unit testing discussions to full coverage of less understood levels integration and system testing. The Fourth Edition: Emphasizes technical inspections and is supplemented by an appendix with a full package of documents required for a sample Use Case technical inspection Introduces an innovative approach that merges the Event-Driven Petri Nets from the earlier editions with the "Swim Lane" concept from the Unified Modeling Language (UML) that permits model-based testing for four levels of interaction among constituents in a System of Systems Introduces model-based development and provides an explanation of how to conduct testing within model-based development environments Presents a new section on methods for testing software in an Agile programming environment Explores test-driven development, reexamines all-pairs testing, and explains the four contexts of software testing Thoroughly revised and updated, Software Testing: A Craftsman’s Approach, Fourth Edition is sure to become a standard reference for those who need to stay up to date with evolving technologies in software testing. Carrying on the tradition of previous editions, it will continue to serve as a valuable reference for software testers, developers, and engineers.
How American bicyclists shaped the landscape and left traces of their journeys for us in writing, illustrations, and photographs. In the later part of the nineteenth century, American bicyclists were explorers, cycling through both charted and uncharted territory. These wheelmen and wheelwomen became keen observers of suburban and rural landscapes, and left copious records of their journeys—in travel narratives, journalism, maps, photographs, illustrations. They were also instrumental in the construction of roads and paths (“wheelways”)—building them, funding them, and lobbying legislators for them. Their explorations shaped the landscape and the way we look at it, yet with few exceptions their writings have been largely overlooked by landscape scholars, and many of the paths cyclists cleared have disappeared. In Old Wheelways, Robert McCullough restores the pioneering cyclists of the nineteenth century to the history of American landscapes. McCullough recounts marathon cycling trips around the Northeast undertaken by hardy cyclists, who then describe their journeys in such magazines as The Wheelman Illustrated and Bicycling World; the work of illustrators (including Childe Hassam, before his fame as a painter); efforts by cyclists to build better rural roads and bicycle paths; and conflicts with park planners, including the famous Olmsted Firm, who often opposed separate paths for bicycles. Today's ubiquitous bicycle lanes owe their origins to nineteenth century versions, including New York City's “asphalt ribbons.” Long before there were “rails to trails,” there was a movement to adapt existing passageways—including aqueduct corridors, trolley rights-of-way, and canal towpaths—for bicycling. The campaigns for wheelways, McCullough points out, offer a prologue to nearly every obstacle faced by those advocating bicycle paths and lanes today. McCullough's text is enriched by more than one hundred historic images of cyclists (often attired in skirts and bonnets, suits and ties), country lanes, and city streets.
Scores of talented and dedicated people serve the forensic science community, performing vitally important work. However, they are often constrained by lack of adequate resources, sound policies, and national support. It is clear that change and advancements, both systematic and scientific, are needed in a number of forensic science disciplines to ensure the reliability of work, establish enforceable standards, and promote best practices with consistent application. Strengthening Forensic Science in the United States: A Path Forward provides a detailed plan for addressing these needs and suggests the creation of a new government entity, the National Institute of Forensic Science, to establish and enforce standards within the forensic science community. The benefits of improving and regulating the forensic science disciplines are clear: assisting law enforcement officials, enhancing homeland security, and reducing the risk of wrongful conviction and exoneration. Strengthening Forensic Science in the United States gives a full account of what is needed to advance the forensic science disciplines, including upgrading of systems and organizational structures, better training, widespread adoption of uniform and enforceable best practices, and mandatory certification and accreditation programs. While this book provides an essential call-to-action for congress and policy makers, it also serves as a vital tool for law enforcement agencies, criminal prosecutors and attorneys, and forensic science educators.
Minnesota’s Twin Cities have long been powerful engines of change. From their origins in the early nineteenth century, the Twin Cities helped drive the dispossession of the region’s Native American peoples, turned their riverfronts into bustling industrial and commercial centers, spread streets and homes outward to the horizon, and reached well beyond their urban confines, setting in motion the environmental transformation of distant hinterlands. As these processes unfolded, residents inscribed their culture into the landscape, complete with all its tensions, disagreements, contradictions, prejudices, and social inequalities. These stories lie at the heart of Nature’s Crossroads. The book features an interdisciplinary team of distinguished scholars who aim to open new conversations about the environmental history of the Twin Cities and Greater Minnesota.
This book introduces SpecDB, an intelligent database created to represent and host software specifications in a machine-readable format, based on the principles of artificial intelligence and unit testing database operations. SpecDB is demonstrated via two automated intelligent tools. The first automatically generates database constraints from a rule-base in SpecDB. The second is a reverse engineering tool that logs the actual execution of the program from the code.
