There should be a German word for that feeling when you desperately need to be somewhere on time, and the traffic lights seem like they’re conspiring against you. When the greens feel especially short, the reds especially long, and both appear as if they’re in cahoots to keep you idling.
It’s not a conspiracy, but it is something called fixed time control. Most intersections, if they don’t have embedded sensors under the road, abide by traffic light timing determined by observed data from years or months past. Fixed time control based on historical data is usually pretty accurate for specific intersections, but what if entire cities coordinated their traffic lights to cut down on mass commute times and fuel use?
The thermometer showed a 103.5-degree fever, and her 10-year-old’s asthma was flaring up. Mary Bolender, who lives in Las Vegas, needed to get her daughter to an emergency room, but her 2005 Chrysler van would not start.
The cause was not a mechanical problem — it was her lender.
Ms. Bolender was three days behind on her monthly car payment. Her lender, C.A.G. Acceptance of Mesa, Ariz., remotely activated a device in her car’s dashboard that prevented her car from starting. Before she could get back on the road, she had to pay more than $389, money she did not have that morning in March.
Big data is affecting on-the-floor work among caregivers in numerous ways. One of them is in the decision-making process, bedside.
“With the advent of [electronic medical records],” said Mickey Lynch, director of commercial strategy and innovation at Cadient Group, “a physician has a much broader set of information upon which to establish a path forward. Meaning that now he or she can quickly view notes from previous visits, quickly access lab values and access test results perhaps administered by other physicians. All of which provides the physician with a far more robust clinical view of the patient.”
Another way big data is making changes — how medical facilities are managed and leveraged to optimize resources around patient-traffic trends.
“I no longer look at somebody’s CV to determine if we will interview them or not,” declares Teri Morse, who oversees the recruitment of 30,000 people each year at Xerox Services. Instead, her team analyses personal data to determine the fate of job candidates.
She is not alone. “Big data” and complex algorithms are increasingly taking decisions out of the hands of individual interviewers – a trend that has far-reaching consequences for job seekers and recruiters alike.
What is big data?
It’s a bit of a misnomer: “Ex-Guardian writer Simon Rogers once said, ‘Big data is data that is one bit too much for you to be comfortable’, and this is probably the best definition I’ve read.
“The volume of data is not irrelevant, but not as important as it sounds. More important is the ability to link diverse datasets with each other.”
– Giuseppe Sollazzo, senior systems analyst at St George’s, University of London, and member of the open data user group
It’s about time we dropped the “big” jargon: “It’s just data. Data volume and velocity is exponentially increasing, but has always been too big to easily store and process … One thing that has changed in the last few years is the recognition from decision makers – not just analysts – that data is a valuable resource.”
– Tom Smith, director of the Oxford Consultants for Social Inclusion
Why is it important for government?
“Joining up public sector data sources can make government more efficient, save money, identify fraud and help public bodies better serve their citizens.”
– Claire Vyvyan, executive director and general manager of public sector at Dell UK
“Data can enable government to do existing things more cheaply, do existing things better and do new things we don’t currently do.”
– Tom Heath, head of research at the Open Data Institute
The importance of algorithms in our lives today cannot be overstated. They are used virtually everywhere, from financial institutions to dating sites. But some algorithms shape and control our world more than others — and these ten are the most significant.
Just a quick refresher before we get started. Though there’s no formal definition, computer scientists describe algorithms as a set of rules that define a sequence of operations. They’re a series of instructions that tell a computer how it’s supposed to solve a problem or achieve a certain goal. A good way to think of algorithms is by visualizing a flowchart.
