In TEST VALIDATION IN EMPLOYMENT SETTINGS, industrial psychology expert witness Robert Rose, PhD, and his partner at Rose Porterfield Group, Inc., Robyn W. Porterfield, PhD, write on employment testing. They have co-written articles including a column for the Dallas Business Journal titled “C-level coach.

If a selection procedure is challenged for adverse impact its validity becomes important. “Validity” is the extent to which test results are related to performance on the job. And, legal issues aside, it is best for the organization to have valid procedures. There are a few key points you need to consider if involved in litigation around testing issues and/or advising clients to avoid issues.

Everything you use to hire or promote is a test. Period. If all you do to hire is interview you have to show that the interview is valid – and that may be difficult.

Bus and truck accident expert witnesses may consult regarding transportation accidents, bus accidents, truck safety, and bus safety. This weekend, investigators said that the FedEx truck that slammed into a tour bus full of students in Orland, CA, could have been on fire right before the deadly crash. The truck crossed a median into oncoming traffic which resulted in the death of 10 people. Highway Safety Investigator Robert Accetta will serve as the The National Transportation Safety Board investigator-in-charge. The NTSB website includes Safety Studies.

NTSB Safety Studies are examinations on topics such as the effectiveness of, or need for, actions by a Government agency in reducing transportation losses, the technical aspects of a transportation system, analysis of accident data, or the history and progress of transportation safety improvements. The study results in the issuance of a narrative report on the facts, conclusions and any applicable recommendations.

One of these reports is Crashes Involving Single-Unit Trucks that Resulted in Injuries and Deaths. Safety Study NTSB/SS-13/01. Washington, DC.

In The Internet of Things, for Better or Worse, internet security expert witness Steve Burgess writes on networked devices. Burgess Forensics has offered computer forensic and electronic discovery as well as expert witness testimony since 1985.

What kinds of devices make up the Internet of Things (“IoT”)? Anything Internet-connected, which can currently include everything from computer to coffeemaker, from range to refrigerator, from baby monitor to burglar alarm, from car to crockpot. And because they’re Internet-connected some people are afraid that these devices may be subject to malware that will cause them to become zombies.

And indeed, unauthorized use of internet-connected devices has already begun. Around the end of 2013, about 100,000 such devices were used to send about 750,000 spam messages. Seven messages per device is not much, but it is indicative of a real problem. And the low number per device may have been by design, so as to avoid detection. What to do?

A transportation safety expert witness testified in the case against General Motors brought by the parents of Brooke Melton. The expert reported that information recorded in the black box in the fatal accident showed the key had slipped from the “on” to the “accessory” position three seconds before the accident, shutting off her power steering and power brakes.

On April 1, 2014, General Motors’ CEO Mary Barra will testify before a congressional subcommittee about the widening safety recall on GM pre-2008 ignition switches. Ignition switches moving from the “run” position to the “accessory” or “off” position during a crash may disable the air bag sensing system. The recall follows 12 deaths and 31 crashes in 2005-07 Chevrolet Cobalts, 2003-07 Saturn Ions and several other pre-2008 models with the same ignition switch. As a precaution, NHTSA urges owners of recalled GM vehicles – 2005-07 Chevrolet Cobalt, 2007 Pontiac G5, 2003-07 Saturn Ion, 2006-07 Chevrolet HHR, 2006-07 Pontiac Solstice, 2007 Saturn Sky – to follow GM recommendation to “use only the ignition key with nothing else on the key ring” and get repairs as soon as parts are available from GM.

An armed intruder approaches your building – what kind of resistance will they encounter?

Effective access control, automated communication, and rehearsed emergency plans are your best defenses against workplace violence. These measures may not prevent an aggressor from entering your building, but they will create necessary delays in a situation where every second counts.

In Child Abuse Pediatrician’s Role, Child Abuse Pediatrics & Forensic Medicine Experts explains failure to thrive.

Failure to Thrive is a condition whereby children either do not receive or are unable to properly utilize adequate nutrition for sufficient growth. There are two categories of causality for Failure to Thrive: organic and non-organic. Organic Failure to Thrive is the type caused by medical conditions. Non-organic Failure to Thrive is caused by either insufficient provision of food, or complex psychosocial factors that impair a child’s ability to accept food provided.
