New report recommends technology, policy changes to better protect older children and adolescents in crashes
2013 A research report released today from The Children's Hospital of Philadelphia (CHOP) provides specific recommendations for optimizing the rear seat of passenger vehicles to better protect its most common occupants children and adolescents. By bringing technologies already protecting front seat passengers to the rear seat and modifying the geometry of the rear seat to better fit this age group, the US could achieve important reductions in serious injury and death. Motor vehicle crashes remain the leading cause of death for children older than 4 years and resulted in 952 fatalities in 2010 for children age 15 and younger.
"Our review of the current science and data regarding rear seat occupant safety found clear evidence that use of a child restraint system (CRS) is protective for younger children. However, older children who have outgrown child safety seats and booster seats are at greater risk of injury," says Kristy Arbogast, PhD, lead author of the report and director of engineering at the Center for Injury Research and Prevention at CHOP. "Many technologies that protect front seat passengers, such as load limiters and pretensioners, are not commonly found in the rear seat even though sled tests and computer modeling suggest that these seat belt features have the potential to reduce the risk of serious head and chest injury for rear seated occupants."
In addition to front seat restraints, CHOP researchers suggest that cues can be taken from booster seat design to determine how to keep kids who have outgrown boosters properly positioned in vehicle seat belts so the restraint can perform properly. They propose that adjustments to the geometry of the rear seat including shorter seat cushions, lower seat belt anchorages and contoured seats could increase comfort, keep the shoulder belt in position and, in side impact crashes, reduce lateral movement.
"For children under age 13, the rear seat is still the safer seating position as compared to the front seat of passenger vehicles," says Dr. Arbogast. "But we can do a better job at protecting children who have outgrown add-on restraints."
The report authors recommend the development of regulatory procedures or vehicle performance assessment programs for consumers that evaluate protection of rear seat occupants. Common vehicle rating systems do not evaluate the safety of rear seat occupants in frontal crashes. In addition to engineering solutions, the report also recommends policies and programs to increase rear seat restraint use, which remains lower than front seat restraint use and is a key risk factor for dying in a crash. Additional research is needed to further inform these priorities.

Police swarmed a Boston suburb this morning as an “armed and dangerous” suspect of the Boston marathon bombings is at large. The drama unfolded last night after the two suspects, brothers from Chechnya, were in a gun battle that left one officer dead at the MIT campus. The two marathon bombers are brothers from Chechyna. ...
At the beginning of this month, a judge in New York City demanded removal of the age restriction on the morning-after pill birth control prescription. The consequential legal battle has raised the following question: Is it ethical to give girls under the age of 17 access to the morning-after pill, or are these individuals not yet mature enough to use such a contraceptive?
Hapyrus has launched FlyData, technology that enables it to automatically upload and migrate data to Amazon Redshift, the data-warehouse service that can scale to petabyte size. Amazon has claimed that Redshift will increase the speed of query performance when analyzing any size data set, using the same SQL-based business intelligence tools analysts use today. Hapyrus Co-Founder Koichi Fujikawa says their service, a big data router, makes Redshift even more effective and an alternative to Hadoop and Hive, the most widely recognized combination used for processing and analyzing data. After setup, FlyData runs in the background, moving the data to Redshift. Fujikawa said Hapyrus sets up a virtual private cloud on AWS. Customers can integrate their own virtual private network to transfer the data. Hapyrus competes against the likes of Informatica and Talend. Its current focus is on integrating with AWS, but going forward it will integrate data from a variety of sources. Fujikawa said in an email that Informatica and Talend provide complex data-integration solutions for big enterprise customers — mainly for on-premise systems. “We provide our data-integration service for cloud components like Redshift for any size of companies, from startups to relatively big organizations,” he said. Fujikawa says Redshift can be 10 times faster than?Hadoop?and Hive. Customers he hears from say they are seeking alternatives for the everyday kind of work that needs to get done. They can get stymied by the time and the expense that a query takes when using Hadoop and Hive. But there are also complexities with using Redshift, as Airbnb discovered: First, in order to load your data into Redshift, it has to be in either S3 or Dynamo DB already. The default data loading is single threaded and could take a long time to load all your data. We found breaking data into slices and loading them in parallel helps a lot. On its nerd blog, Airbnb said Redshift lacks some of the features that come with Hadoop. But data analysts are liking it so much that they want to use it pretty much exclusively. The Airbnb nerd blog makes the point that, in the end, Redshift and Hadoop may be more compatible than anything else. “Redshift, as a data warehouse, should be compared to Vertica, Greenplum, AsterData, Impala, Hadapt, and CitusData,” said Drawn to Scale Co-Founder Bradford Stephens in a recent email interview. “They’re just different things.” The smallest of startups take
Tumblr has let go of the four-person editorial team behind Storyboard, an experimental initiative to highlight users and organizations on the blogging platform, less than one year after the project went live. In a blog post, Tumblr founder and CEO David Karp said “what we?ve accomplished with Storyboard has run its course for now, and our editorial team will be closing up shop and moving on. I want to personally thank them for their great work. And please join us in wishing them well.” Storyboard was launched last May, with Chris Mohney as its first editor-in-chief and Jessica Bennett as executive editor. Both came with plenty of publishing experience–Mohney was previously the editor of Gawker and Gridskipper and oversaw Blackbook magazine, while Bennett had formerly worked at The Daily Beast. The other two members of the team are editorial producer?Sky Dylan-Robbins and editorial director Christopher Price.?Storyboard’s initial features included one on the companion Tumblr set up by New York Times’ photo archive, an interview with pianist and Tumblr user Dotan Negrin, and an infographic charting the many “Fuck Yeah” blogs set up on the platform. In an interview with Fast Company just after Storyboard’s launch last year, Mohney said “this is the first thing Tumblr has done that has a significant outward-facing goal.” Mohney added monetization wasn’t an initial goal of the project and there were few immediate benefits for sponsors on Storyboard: “Tumblr?s revenue plan is to find partners who are interested in doing creative stuff on Tumblr as opposed to just bringing in banner ads. If (advertisers) are doing something great as part of their sponsorship program, they?ll get a lot more recognition out of that than from our editorial recognition.” It seems like Storyboard’s lofty but less-than-lucrative directive may have fallen by the wayside as six-year-old Tumblr focuses on finally turning its first annual profit after allowing advertisers to pay for more prominent posts on its Web version and mobile app. Inside of using banner ads and keywords–or placement on Storyboard–Twitter’s advertising system gives sponsors the chance to get more views and reblogs. Twitter’s vice president Derek Gottfrid recently told Bloomberg that Tumblr’s mobile users have quadrupled over the past six months, bringing the total closer to the number of Web users and making the advertising initiative more important. Tumblr has been emailed for comment.
