Around the globe, democracy is under assault. For a dozen years, global freedom has followed a downward slope, according to Freedom House. Once viewed as the world's model of freedom, the United States has slipped in world ratings of democracy. For a rising portion of the world's population, faith in democracy is flagging. At the same time, a wave of nationalism and xenophobia is rising in the West, questioning democracy's ability to meet the needs of its citizens. The contributors to this volume examine democracy's discontent from a variety of perspectives. What forces have produced the extreme partisanship and polarization roiling America's civic life and politics? How has today's populist movement challenged democratic norms and institutions? What role has social media played in democracy's discontent and its defense? How do we overcome persistent racism in the face of emboldened White supremacist and anti-immigrant agitation? Across the pages of this book, teachers, teacher educators, and education policy makers will recognize a common theme in responding to democracy's discontent - the need to rebuild the nation's civic infrastructure. Research on best practices in civic learning and engagement serve as a guide to transforming how we prepare citizens for democratic deliberation and civic action. Creative and effective teaching materials and approaches await only the will to invest the needed time and support. Repairing our civic infrastructure will help to restore confidence in our civic capabilities and trust in our ability to work together for the public good. Without a serious recommitment to the civic mission of schools, the nation will be ill prepared to defend against those within and beyond our borders who are intent on undermining democracy.

New Techniques in Cardiothoracic Imaging emphasizes emerging methods in computed tomography, magnetic resonance imaging, positron-emission tomography, and similar technology. Effective use of these tools can facilitate the identification, analysis, and treatment of diseases and disorders commonly encountered in daily clinical practice. The contributors to this volume discuss: PET-CT Cardiac CT Multidetector-row helical CT High-resolution CT of the lungs Cardiac MR Functional MR Digital chest radiography Bringing readers to the forefront of the field with expert assessments of new and emerging technologies that are impacting cardiothoracic imaging, the book presents the work of seasoned experts who have developed a thorough clinical and basic knowledge in this evolving discipline and provide practical guidance on incorporating new techniques from the laboratory to the clinical practice. More than 250 highly-detailed scientific images enhance the text.

Based on the learning goals of the Society of Thoracic Radiology Curriculum in Cardiac Radiology, Cardiac Imaging presents core knowledge that must be learned to accurately and effectively interpret cardiac imaging studies. This book imparts essential facts about all imaging modalities and the basics of interpretation and technique in a concise and readable format. Part of the Rotations in Radiology series, this book offers a guided approach to imaging diagnosis. Each pathology is covered within a targeted discussion that reviews the definition, clinical features, anatomy and physiology, how to approach the image, what not to miss, differential diagnosis, clinical issues, key points, and key references. The book's manageable size is ideal for Residents' use during training on a specific rotation and for exam review, or as a quick refresher for the established Radiologist.
