The events of January 6, 2021, when violent rioters attacked the Capitol building in Washington in order to disrupt validation of the 2020 presidential election, forced an unprecedented reckoning with the state of American politics. Members of Congress struggled to account for the rhetoric that gave rise to the event; law enforcement grappled with the challenge of holding accountable those who perpetrated the violence; and journalistic outlets wrestled with reporting a complex web of conspiracy theories and disinformation that gave rise to the insurrection. But for senior military leaders, the question was how to explain the troubling presence of active duty servicemembers and veterans in the first attack on the American seat of government in two centuries. The result is a profound and urgent discussion in U.S. civil-military relations.  相似文献

The American defense establishment has come to think of itself as the victim of complex and demanding threats, political irresponsibility and public apathy. While true, such conditions are often the case in American history. “Don’t fight the problem” is a standard instruction in war games. The Department of Defense should adopt that approach with its budget and strategy: stop submitting budgets in excess of legislated limits and devise a strategy consistent with them. It should explore alternative ways to achieve policy objectives, develop a concrete means of assessing risk, and on that basis build greater support for its preferred strategy.  相似文献

America's military has proven incredibly effective and adaptive to the threats of the 9/11 era. It has not, however, been particularly cost-conscious. Insolvency is our gravest national security threat, and – thankfully – the Congress has finally gotten serious about dealing with it. Defense is in for a decade of austerity, of a magnitude that cannot be accommodated within current strategy and forces. Much higher risk will need to be accepted in how we fight our wars and address threats of lesser magnitude or longer lead times unless we find more innovative approaches. Foregoing counterinsurgencies, simplifying our war aims, protecting our advantages in creativity, restructuring military benefits, shifting greater responsibility to allies and emphasizing cost-exchange ratios in our operations will be necessary. It is a daunting list, and wearying to a military that has shouldered the burdens of wars for a decade with little contribution from our broader society. But it, or something like it, will also be necessary to redress the dangerous vulnerability or our debt.  相似文献

Recently, cloud point extraction (CPE) coupled with back extraction (BE) has been suggested as a promising alternative to liquid-liquid extraction. In CPE, non-ionic surfactants in aqueous solutions form micelles and the solution becomes turbid when heated to the cloud point temperature. Microwave- or ultrasonic-assisted BE can be performed after CPE and before injection of the sample for instrumental analysis by ultraviolet-visible spectroscopy, high-performance liquid chromatography, gas chromatography, gas chromatography-mass spectrometry, or liquid chromatography-mass spectrometry. This article reviews selected published scientific research on the application of CPE-BE to the determination of alkaloids, drugs and organophosphorus compounds from several complex matrices. This method could be scaled-up for use in forensic science.  相似文献

A Midwestern state’s child welfare agency contracted with a university to evaluate a 5-year Title IV-E Waiver Demonstration Project. As part of the process study, evaluators employed case study analysis to investigate Waiver knowledge and effects as reported by Regional and Executive Managers across 4 years of the demonstration period. Data from 78 interviews reveal enhanced levels of manager–evaluator rapport and integrated Waiver knowledge across years of data collection. This study highlights the value of middle managers as rich data sources, studying process through qualitative methods in child welfare evaluation, and how consistent relationships can support partnerships over time.  相似文献
