Michelle Nunn’s midterm result shows that Georgia’s demographics may be shifting to favor the Democrats
No full textIn Georgia’s Senate race Republican David Purdue defeated Democrat Michelle Nunn by nearly eight points, despite polling that had shown a much closer contest. Jamie L. Carson, Joel Sievert, and Ryan D. Williamson reflect on Georgia’s midterm election results, writing that in gaining more than 40 percent of the vote, Nunn outperformed many previous Democratic candidates in the state. They argue that if the Democratic Party continues to field good candidates in Georgia, shifting demographics may mean that they will be able to take statewide races within a few election cycles

The SIEVERT system for aircrew Dosimetry
No full textInternational audienceFlight personnel are likely to receive an effective dose of several mSv in 1 y of professional activity. In France, the order of 8 December 2003 requires airline companies to monitor the exposure of their flight personnel. This is why public authorities have made the SIEVERT system (a system for evaluating exposure to cosmic radiation in air transport), available to French airlines, to evaluate doses. The SIEVERT system has been operational for use by airlines since the start of summer 2001. So far, more than 2.5 million flights have been processed at the request of more than 30 French airlines. Furthermore, this system was opened to the public in March 2002 (http://www.sievert-system.org), so that every passenger can calculate the dose received during a flight. © The Author 2009.

Replication Data for: Nationalization and the Incumbency Advantage
No full textLegislative scholars have investigated both the growth in the incumbency advantage since the early 1970s as well as its decline in recent decades, but there are several unanswered questions about this phenomenon. In this paper, we examine the incumbency advantage across a much wider swath of history to better understand its connection with changing levels of electoral nationalization. Based on an analysis of U.S. House elections extending back to the antebellum era, we find that the incumbency advantage fluctuates in predictable ways over time with changes in nationalization, which can be a product of both institutional and political conditions. We also demonstrate that the increased influence of local forces in congressional elections may not be strictly necessary nor sufficient for the existence of an incumbency advantage

Taming PITCHf/x Data with XML2R and pitchRx
No full textXML2R is a framework that reduces the effort required to transform XML content into tables in a way that preserves parent to child relationships. pitchRx applies XML2R’s grammar for XML manipulation to Major League Baseball Advanced Media (MLBAM)’s Gameday data. With pitchRx, one can easily obtain and store Gameday data in a remote database. The Gameday website hosts a wealth of XML data, but perhaps most interesting is PITCHf/x. Among other things, PITCHf/x data can be used to recreate a baseball’s flight path from a pitcher’s hand to home plate. With pitchRx, one can easily create animations and interactive 3D scatterplots of the baseball’s flight path. PITCHf/x data is also commonly used to generate a static plot of baseball locations at the moment they cross home plate. These plots, sometimes called strike-zone plots, can also refer to a plot of event probabilities over the same region. pitchRx provides an easy and robust way to generate strike-zone plots using the ggplot2 package
Interfacing R with Web Technologies for Interactive Statistical Graphics and Computing with Data
No full textThe following describes a collection of software interfaces for data acquisition and visualization. All of these interfaces are freely available as extension packages to the R language and leverage web technologies to support accessible and portable data science workflows. The majority of this work (LDAvis, animint, and plotly) focuses on interactive visualization. These interfaces fall roughly into two categories: (1) domain-specific (LDAvis) and (2) general purpose tools for interactive data visualization (animint and plotly). More specifically, the LDAvis package produces an interactive visualization to aid interpretation of Latent Dirichlet Allocation (LDA) model output. The animint and plotly packages are more general, and both aim to make interactive web graphics a practically useful tool for common exploratory data analysis tasks.</p
