Contains 11 relevant, practice-oriented topics including conductive hearing loss in children; congenital cystic neck masses; common solid and vascular neck masses in children; pediatric facial and paranasal sinus infections; infectious and inflammatory processes of the orbits in children; and more.  Provides in-depth clinical reviews on pediatric head and neck imaging, offering actionable insights for clinical practice.  Presents the latest information on this timely, focused topic under the leadership of experienced editors in the field. Authors synthesize and distill the latest research and practice guidelines to create clinically significant, topic-based reviews. 

World War II is raging when virtually an entire squadron of new fighter planes depart Tarawa for a seven hundred mile flight south.

It's supposed to be a routine trip, but only Lt. Jack Page, a member of the Marine Corps Reserves, makes it to his destination. Twenty-two other pilots are missing, and it's up to Major Rum Collins to find out what went wrong.

With so many messages rocketing across the Pacific, it is hard to track down any of the pilots. Collins wonders where they are, why no emergency radio signals were detected and if it's possible that the Japanese somehow took the pilots as prisoners.

While Collins and his close circle of fellow Marines know that they are investigating one of the worst disasters in aviation history, they keep the story under wraps. The investigation is labeled top secret, and everyone waits for the truth to be discovered in "Sea Eagle Down."

This study examines several unexplored aspects of Robert Frost’s poetry—proverbs, riddles, and names—and shows how they contribute to the reader's experience. Timothy D. O'Brien argues that while they often shape Frost’s poems as sites of inviting wisdom and play, these features also open up the poems to radical doubt about identity, authorship, and reality. This book offers the most extensive research to date of the relationship between Frost’s poetry and the visual art that often accompanied it and sheds new light on the work of one of the twentieth century’s most highly regarded poets.    

Urban Informatics: Using Big Data to Understand and Serve Communities introduces the reader to the tools of data management, analysis, and manipulation using R statistical software. Designed for undergraduate and above level courses, this book is an ideal onramp for the study of urban informatics and how to translate novel data sets into new insights and practical tools. The book follows a unique pedagogical approach developed by the author to enable students to build skills by pursuing projects that inspire and motivate them. Each chapter has an Exploratory Data Assignment that prompts readers to practice their new skills on a data set of their choice. These assignments guide readers through the process of becoming familiar with the contents of a novel data set and communicating meaningful insights from the data to others. Key Features: The technical curriculum consists of both data management and analytics, including both as needed to become acquainted with and reveal the content of a new data set. Content that is contextualized in real-world applications relevant to community concerns. Unit-level assignments that educators might use as midterms or otherwise. These include Community Experience assignments that prompt students to evaluate the assumptions they have made about their data against real world information. All data sets are publicly available through the Boston Data Portal.

This fully revised second edition of Top 3 Differentials in Radiology provides a comprehensive core exam review of frequently encountered imaging gamuts in all major radiological subspecialties. Author William O'Brien utilizes the widely acclaimed format of his first edition, with 330 new and updated radiology cases organized into 12 core subspecialty sections. The last section, "Roentgen Classics," includes cases from each of the previous core sections, with imaging findings characteristic of a single diagnosis. This book reflects content included in the current radiology board examinations with accurate and concise descriptions of key differentials, which are integral to acing the boards. Each case is formatted as a two-page unit. The left page features clinical images, succinctly captioned radiographic findings, and pertinent clinical history. The right page includes the key imaging gamut, differential diagnoses rank-ordered by the Top 3, additional diagnostic considerations, and clinical pearls. Key Features More than 700 high quality images, including advanced imaging techniques Rank ordered differentials organized into the Top 3 and additional diagnostic considerations A high-yield review of important imaging and clinical manifestations for all entities on the list of differentials Imaging pearls at the end of each case provide a quick review of key points This outstanding resource provides radiologists and trainees with a solid foundation of core radiology topics and a wide spectrum of key imaging findings encountered in clinical practice. It is a must-have for radiology residents preparing for board examinations. Veteran radiologists looking for a comprehensive review of critical topics in radiology will also find this book invaluable.

The future of smart cities has arrived, courtesy of citizens and their phones. To prove it, Daniel T. O'Brien explains the transformative insights gleaned from years researching Boston's 311 reporting system, a sophisticated city management tool that has revolutionized how ordinary Bostonians use and maintain public spaces. Through its phone service, mobile app, website, and Twitter account, 311 catalogues complaints about potholes, broken street lights, graffiti, litter, vandalism, and other issues that are no one citizen's responsibility but affect everyone's quality of life. The Urban Commons offers a pioneering model of what modern digital data and technology can do for cities like Boston that seek both prosperous growth and sustainability. Analyzing a rich trove of data, O'Brien discovers why certain neighborhoods embrace the idea of custodianship and willingly invest their time to monitor the city's common environments and infrastructure. On the government's side of the equation, he identifies best practices for implementing civic technologies that engage citizens, for deploying public services in collaborative ways, and for utilizing the data generated by these efforts. Boston's 311 system has narrowed the gap between residents and their communities, and between constituents and local leaders. The result, O'Brien shows, has been the creation of more effective policy and practices that reinvigorate the way citizens and city governments approach their mutual interests. By unpacking when, why, and how the 311 system has worked for Boston, The Urban Commons reveals the power and potential of this innovative system, and the lessons learned that other cities can adapt.
