  dod annual security awareness refresher test answers: Cyber-Security and Threat Politics Myriam Dunn Cavelty, 2007-11-28 This book explores the political process behind the construction of cyber-threats as one of the quintessential security threats of modern times in the US. Myriam Dunn Cavelty posits that cyber-threats are definable by their unsubstantiated nature. Despite this, they have been propelled to the forefront of the political agenda. Using an innovative theoretical approach, this book examines how, under what conditions, by whom, for what reasons, and with what impact cyber-threats have been moved on to the political agenda. In particular, it analyses how governments have used threat frames, specific interpretive schemata about what counts as a threat or risk and how to respond to this threat. By approaching this subject from a security studies angle, this book closes a gap between practical and theoretical academic approaches. It also contributes to the more general debate about changing practices of national security and their implications for the international community.

  dod annual security awareness refresher test answers: Improving Diagnosis in Health Care National Academies of Sciences, Engineering, and Medicine, Institute of Medicine, Board on Health Care Services, Committee on Diagnostic Error in Health Care, 2015-12-29 Getting the right diagnosis is a key aspect of health care - it provides an explanation of a patient's health problem and informs subsequent health care decisions. The diagnostic process is a complex, collaborative activity that involves clinical reasoning and information gathering to determine a patient's health problem. According to Improving Diagnosis in Health Care, diagnostic errors-inaccurate or delayed diagnoses-persist throughout all settings of care and continue to harm an unacceptable number of patients. It is likely that most people will experience at least one diagnostic error in their lifetime, sometimes with devastating consequences. Diagnostic errors may cause harm to patients by preventing or delaying appropriate treatment, providing unnecessary or harmful treatment, or resulting in psychological or financial repercussions. The committee concluded that improving the diagnostic process is not only possible, but also represents a moral, professional, and public health imperative. Improving Diagnosis in Health Care, a continuation of the landmark Institute of Medicine reports To Err Is Human (2000) and Crossing the Quality Chasm (2001), finds that diagnosis-and, in particular, the occurrence of diagnostic errorsâ€has been largely unappreciated in efforts to improve the quality and safety of health care. Without a dedicated focus on improving diagnosis, diagnostic errors will likely worsen as the delivery of health care and the diagnostic process continue to increase in complexity. Just as the diagnostic process is a collaborative activity, improving diagnosis will require collaboration and a widespread commitment to change among health care professionals, health care organizations, patients and their families, researchers, and policy makers. The recommendations of Improving Diagnosis in Health Care contribute to the growing momentum for change in this crucial area of health care quality and safety.
  dod annual security awareness refresher test answers: Partnership for the Americas: Western Hemisphere Strategy and U.S. Southern Command James G. Stavridis, Radm James G Stavridis, 2014-02-23 Since its creation in 1963, United States Southern Command has been led by 30 senior officers representing all four of the armed forces. None has undertaken his leadership responsibilities with the cultural sensitivity and creativity demonstrated by Admiral Jim Stavridis during his tenure in command. Breaking with tradition, Admiral Stavridis discarded the customary military model as he organized the Southern Command Headquarters. In its place he created an organization designed not to subdue adversaries, but instead to build durable and enduring partnerships with friends. His observation that it is the business of Southern Command to launch ideas not missiles into the command's area of responsibility gained strategic resonance throughout the Caribbean and Central and South America, and at the highest levels in Washington, DC.

  dod annual security awareness refresher test answers: Pain Management and the Opioid Epidemic National Academies of Sciences, Engineering, and Medicine, Health and Medicine Division, Board on Health Sciences Policy, Committee on Pain Management and Regulatory Strategies to Address Prescription Opioid Abuse, 2017-09-28 Drug overdose, driven largely by overdose related to the use of opioids, is now the leading cause of unintentional injury death in the United States. The ongoing opioid crisis lies at the intersection of two public health challenges: reducing the burden of suffering from pain and containing the rising toll of the harms that can arise from the use of opioid medications. Chronic pain and opioid use disorder both represent complex human conditions affecting millions of Americans and causing untold disability and loss of function. In the context of the growing opioid problem, the U.S. Food and Drug Administration (FDA) launched an Opioids Action Plan in early 2016. As part of this plan, the FDA asked the National Academies of Sciences, Engineering, and Medicine to convene a committee to update the state of the science on pain research, care, and education and to identify actions the FDA and others can take to respond to the opioid epidemic, with a particular focus on informing FDA's development of a formal method for incorporating individual and societal considerations into its risk-benefit framework for opioid approval and monitoring.

Over thirty years ago, sociologist and University of California, Berkeley professor Arlie Hochschild set off a tidal wave of conversation and controversy with her bestselling book, The Second Shift. Hochschild's examination of life in dual-career housholds finds that, factoring in paid work, child care, and housework, working mothers put in one month of labor more than their spouses do every year. Updated for a workforce that is now half female, this edition cites a range of updated studies and statistics, with an afterword from Hochschild that addresses how far working mothers have come since the book's first publication, and how much farther we all still must go.

  dod annual security awareness refresher test answers: A Historical Review and Analysis of Army Physical Readiness Training and Assessment Whitfield East, 2013-12 The Drillmaster of Valley Forge-Baron Von Steuben-correctly noted in his Blue Book how physical conditioning and health (which he found woefully missing when he joined Washington's camp) would always be directly linked to individual and unit discipline, courage in the fight, and victory on the battlefield. That remains true today. Even an amateur historian, choosing any study on the performance of units in combat, quickly discovers how the levels of conditioning and physical performance of Soldiers is directly proportional to success or failure in the field. In this monograph, Dr. Whitfield Chip East provides a pragmatic history of physical readiness training in our Army. He tells us we initially mirrored the professional Armies of Europe as they prepared their forces for war on the continent. Then he introduces us to some master trainers, and shows us how they initiated an American brand of physical conditioning when our forces were found lacking in the early wars of the last century. Finally, he shows us how we have and must incorporate science (even when there exists considerable debate!) to contribute to what we do-and how we do it-in shaping today's Army. Dr. East provides the history, the analysis, and the pragmatism, and all of it is geared to understanding how our Army has and must train Soldiers for the physical demands of combat. Our culture is becoming increasingly ''unfit, due to poor nutrition, a lack of adequate and formal exercise, and too much technology. Still, the Soldiers who come to our Army from our society will be asked to fight in increasingly complex and demanding conflicts, and they must be prepared through new, unique, and scientifically based techniques. So while Dr. East's monograph is a fascinating history, it is also a required call for all leaders to better understand the science and the art of physical preparation for the battlefield. It was and is important for us to get this area of training right, because getting it right means a better chance for success in combat.

  dod annual security awareness refresher test answers: Lying to Ourselves Leonard Wong, Stephen J. Gerras, Strategic Studies Institute, 2015-12-22 One of the hallmarks of a true profession is its ability to assess and regulate itself, especially with respect to adherence to its foundational ethos. Such self-examination is difficult and often causes discomfort within the profession. Nonetheless, it is absolutely necessary to enable members of the profession to render the service for which the profession exists. U.S. military professionals have never shied away from this responsibility, and they do not today, as evidenced by this riveting monograph. Discussing dishonesty in the Army profession is a topic that will undoubtedly make many readers uneasy. It is, however, a concern that must be addressed to better the Army profession. Through extensive discussions with officers and thorough and sound analysis, Drs. Leonard Wong and Stephen Gerras make a compelling argument for the Army to introspectively examine how it might be inadvertently encouraging the very behavior it deems unacceptable.

  dod annual security awareness refresher test answers: National cyber security : framework manual Alexander Klimburg, 2012 What, exactly, is 'National Cyber Security'? The rise of cyberspace as a field of human endeavour is probably nothing less than one of the most significant developments in world history. Cyberspace already directly impacts every facet of human existence including economic, social, cultural and political developments, and the rate of change is not likely to stop anytime soon. However, the socio-political answers to the questions posed by the rise of cyberspace often significantly lag behind the rate of technological change. One of the fields most challenged by this development is that of 'national security'. The National Cyber Security Framework Manual provides detailed background information and in-depth theoretical frameworks to help the reader understand the various facets of National Cyber Security, according to different levels of public policy formulation. The four levels of government--political, strategic, operational and tactical/technical--each have their own perspectives on National Cyber Security, and each is addressed in individual sections within the Manual. Additionally, the Manual gives examples of relevant institutions in National Cyber Security, from top-level policy coordination bodies down to cyber crisis management structures and similar institutions.--Page 4 of cover.
