A poorly performing database application not only costs users time, but also has an impact on other applications running on the same computer or the same network. SQL Tuning provides an essential next step for SQL developers and database administrators who want to extend their SQL tuning expertise and get the most from their database applications.There are two basic issues to focus on when tuning SQL: how to find and interpret the execution plan of an SQL statement and how to change SQL to get a specific alternate execution plan. SQL Tuning provides answers to these questions and addresses a third issue that's even more important: how to find the optimal execution plan for the query to use.Author Dan Tow outlines a timesaving method he's developed for finding the optimum execution plan--rapidly and systematically--regardless of the complexity of the SQL or the database platform being used. You'll learn how to understand and control SQL execution plans and how to diagram SQL queries to deduce the best execution plan for a query. Key chapters in the book include exercises to reinforce the concepts you've learned. SQL Tuning concludes by addressing special concerns and unique solutions to "unsolvable problems."Whether you are a programmer who develops SQL-based applications or a database administrator or other who troubleshoots poorly tuned applications, SQL Tuning will arm you with a reliable and deterministic method for tuning your SQL queries to gain optimal performance.

As Brandon Sanderson’s #1 bestselling Skyward series celebrates its third volume, Cytonic, travel back in time to the origin of Cytonics in the novella Defending Elysium. Centuries before Spensa looked skyward from the planet Detritus—back on Old Earth before it was lost—Jason Write faced a crucial question: was humanity ready to join galactic society? When faster-than-light communications were discovered by a small telephone company in 2071, alien species such as the Tenasi and Varvax overheard them and came to visit Earth. Because the Phone Company controls all communications with the aliens, their operatives like Jason operate above the law. Now, on the space platform Evensong, one of the Phone Company’s scientists has gone missing before surfacing in a hospital with amnesia, and Jason is sent to investigate. Right as he arrives, the body of a murdered Varvax ambassador is discovered, sure to cause a galactic incident. Coln Abrams of the United Intelligence Bureau seizes the opportunity to investigate Jason as he deals with the crisis. This could be the UIB’s chance to discover the Phone Company’s secrets—how does FTL communication work, and what is Jason hiding? Winner of Spain’s UPC Award for Science Fiction in 2007.

Gretchen Krueger's poignant narrative explores how doctors, families, and the public interpreted the experience of childhood cancer from the 1930s through the 1970s. Pairing the transformation of childhood cancer from killer to curable disease with the personal experiences of young patients and their families, Krueger illuminates the twin realities of hope and suffering. In this social history, each decade follows a family whose experience touches on key themes: possible causes, means and timing of detection, the search for curative treatment, the merit of alternative treatments, the decisions to pursue or halt therapy, the side effects of treatment, death and dying—and cure. Recounting the complex and sometimes contentious interactions among the families of children with cancer, medical researchers, physicians, advocacy organizations, the media, and policy makers, Krueger reveals that personal odyssey and clinical challenge are the simultaneous realities of childhood cancer. This engaging study will be of interest to historians, medical practitioners and researchers, and people whose lives have been altered by cancer.

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.

The second edition of a bestselling textbook, Using R for Introductory Statistics guides students through the basics of R, helping them overcome the sometimes steep learning curve. The author does this by breaking the material down into small, task-oriented steps. The second edition maintains the features that made the first edition so popular, while updating data, examples, and changes to R in line with the current version. See What’s New in the Second Edition: Increased emphasis on more idiomatic R provides a grounding in the functionality of base R. Discussions of the use of RStudio helps new R users avoid as many pitfalls as possible. Use of knitr package makes code easier to read and therefore easier to reason about. Additional information on computer-intensive approaches motivates the traditional approach. Updated examples and data make the information current and topical. The book has an accompanying package, UsingR, available from CRAN, R’s repository of user-contributed packages. The package contains the data sets mentioned in the text (data(package="UsingR")), answers to selected problems (answers()), a few demonstrations (demo()), the errata (errata()), and sample code from the text. The topics of this text line up closely with traditional teaching progression; however, the book also highlights computer-intensive approaches to motivate the more traditional approach. The authors emphasize realistic data and examples and rely on visualization techniques to gather insight. They introduce statistics and R seamlessly, giving students the tools they need to use R and the information they need to navigate the sometimes complex world of statistical computing.
