I am not on the Facebook wagon but I found the controversy over Facebook’s Beacon interesting. Users were inadvertently displaying their online purchases to their friends on Facebook. Facebook claims that users could opt-out of showing this information but many users said it was not obvious. Here are some before and after screenshots [from the NYT blog entry]:
The new math and physics building is going up outside my window at North Carolina State. I see the workers out there each day, and as the building gets higher they are obviously required to don different safety gear.
The fuzzy picture below shows two workers on the top level (7th floor) and the green highlight is my outline of the full body harness and safety cord the man is wearing. Indeed, it seemed necessary as whatever tool he is using seems to push him off balance with every use (some sort of nail gun?)
However. Unlike the man behind him, this worker has not attached his safety cord to anything. It merely drags along behind him as he walks around the platform and crawls in and out of the scaffold. In fact, it seems to get in his way when the clasp on the cord catches on the corrugated surface of the platform.
Enjoy this video of expert team performance. I note that the post-er says these Marines “cut a lot of corners.” I’d be very interested to know how this differs from what they “should” be doing and what is optimal.
This from comments on the video: “Chief, what are you doing?! That was one jacked up fire mission. Are you trying to get your guys killed in a training mission? Not swabbing the breach or checking the bore while firing slow burning greenbag?! And what are you doing in the way between the trails? Didn’t do FCATS, did you? Don’t trust the quadrant on the gunner’s side?”
Verizon wireless interpreted an accessibility requirement to require they trigger a notification when the user dials 911. Verizon chose to do this audibly… exactly what you DON’T want when you’re calling the police during an emergency!
“The tone our customer experienced is our interpretation of Section 255 of the Telecommunications Act calling for a provider of telecommunications service to offer service that is accessible and usable by individuals with disabilities. The tone, indicating that 911 has been dialed, is one of several features designed to make wireless service is accessible and easy to use, especially for those with disabilities. Other features include a voice command key where customers can use their voice to dial by name or number; a voice echo feature so that a person who can’t see can hear the number or letter if sending a text; read back text messages and speech output of signal strength, battery strength, missed calls, voicemail, roaming, time and date.”
There sure seem to be lots of medical errors in the news lately. No mention of human factors:
The most recent case happened Friday when, according to the health department, the chief resident started brain surgery on the wrong side of an 82-year-old patient’s head. The patient was OK, the health department and hospital said.
In February, a different doctor performed neurosurgery on the wrong side of another patient’s head, said Andrea Bagnall-Degos, a health department spokeswoman. That patient was also OK, she said.
But in August, a patient died a few weeks after a third doctor performed brain surgery on the wrong side of his head. That surgery prompted the state to order the hospital to take a series of steps to ensure such a mistake would not happen again, including an independent review of its neurosurgery practices and better verification from doctors of surgery plans.
We can surmise from the short news article that the source of the problem seems to be working memory??
In addition to the fine, the state ordered the hospital to develop a neurosurgery checklist that includes information about the location of the surgery and a patient’s medical history, and to put in place a plan to train staff on the new checklist.
LOS ANGELES – The recent chatter on a popular social networking site dealt with a problem often overlooked in medicine: mistakes in patients’ medical charts.The twist was the patients were doctors irked to discover gaffes in their own records and sloppy note-taking among their fellow physicians.
Errors can creep into medical charts in various ways. Doctors are often under time pressure and may find themselves taking shortcuts or not fully listening to a patient’s problems. Others rely on their memory to update their patients’ files at the end of the day. Other mistakes can arise from illegible handwriting or coding problems.
The latest comes from Tanzenia where confusion about patient names earned brain surgery for a twisted knee, and knee surgery for a migraine sufferer.
Mr Didas who had been admitted for a knee operation after a motorbike accident is still recovering from the ordeal – he ended up unconscious in intensive care after his head was wrongly operated on. And chronic migraine sufferer Emmanuel Mgaya is likewise, still recovering from his unplanned knee surgery. The blunder was blamed on both patients having the same first name.
But a hospital official, Juma Mkwawa said it was the worst scandal that had happened at Muhimbili hospital and that, “sharing a first name cannot be an excuse”. The two surgeons responsible have been suspended. (BBC)
It is easy to be the bearer of sad stories and ill tidings. I would rather on a note for a hopeful future. Below are researchers and companies dedicated to identifying and eliminating causes of medical error.
Eye-tracking studies arehot in the web design world, but it can be hard to figure out how to translate the results of these studies into real design implementations. These are a few tips from eye-tracking studies that you can use to improve the design of your webpage.
Authorities on the densely populated Indonesian island of Java concluded in mid-October that the threat was imminent enough to require sending troops to forcibly evacuate tens of thousands of villagers living on the mountain’s slopes, directly in the way of volcanic ash falls, mudslides and perhaps even lava flows …
… that didn’t come. The government said on Thursday that the threat had now subsided enough for most evacuees to return to their homes and lands, and learn whether they had been looted or ruined over the weeks they were left untended.
In just two days, we’ve gotten two more big datapoints for the age-old quandary facing public officials around the world about where to set the threshold for public warnings of less-than-certain disaster.
There doesn’t seem to have been a crying-wolf issue in either case: both Mount Kelud eruptions and North Sea storm-surge floods have wrought devastation in living memory, and the authorities could offer plenty of objective physical grounds for their concerns.
Still, erring on the safe side takes its own toll, both material — the evacuated Indonesians apparently had ample cause to worry about looting — and psychological. Even when they are issued in good faith for good reason, every false alarm can drain some of the menace, and some of the effectiveness, out of the next warning.
