Mobile Ads Move Passengers on Crowded Subway
What do irritable, squished riders on a crowded train do? According to a forthcoming study in the INFORMS journal Marketing Science, they often immerse themselves in their mobile phones to escape the crowd. And they shop and buy more in response to mobile ads in the crowded train.
Riders on Crowded Trains Key on Mobile Ads: Marketing Science Study
A recent university study on the effect of hyper-contextual targeting and physical space found that passengers on crowded subway cars shop and buy more in response to mobile ads than those in less crowded cars.
A key takeaway is that riders in crowded subway trains are good targets for mobile advertising...
The study is published in the INFORMS journal Marketing Science.

Management Science Makes List of Top 25 STEM Majors
Finding the optimal way to use a workforce is not an art — it’s a science. In small groups a missing employee can cause sleepless nights when deadlines approach, while an extra employee can result in missed performance metrics. In large groups, such as Fortune 500 companies, these same problems can cost a company billions of dollars or result in thousands of lost jobs. Management science applies the principles of mathematics to the modern office to streamline processes, cut costs and grow revenue.
O.R. Makes List of Top 5 STEM Professions Employing Women
Have a look for yourself at the five jobs with the highest percentage of women working in the profession...
3. Operations Research Analysts
- Percentage of women employed: 55.4%
- Mean annual wage: $82,940
These analysts use mathematical and analytical methods to help organizations solve complex problems, from using statistics to help inform decisions to gathering input from employees. Most operations research analysts have master’s degrees in operations research, engineering, computer science, mathematics or physics. Some entry-level positions are open to those with bachelor’s degrees.
This field only has 55.4% female workers, but that is still a considerable amount when looking at women in STEM. The reason for this, says analyst Laurie M. Orlov in her article on cio.com, is that jobs in the business technology arena capitalize on women’s greatest strengths in the workplace: “communication, collaboration and problem solving.”
Imperative for Ethical Standards in Analytics: The CAP Model
An established code of ethical behavior for analytics professionals already exists.
That code is part and parcel of the Certified Analytics Professional Program (CAP) – a highly regarded professional certification for analytics practitioners managed by INFORMS – the largest international association of professionals in analytics and operations research.
Among other things, the code establishes certain standards for those who call themselves analytics professionals and guidelines for how they should behave and be judged by their peers and employers.
Data Scientist Hottest Job of 2016
Data scientist, named the best job in America for 2016 by job site Glassdoor, is the sexy mashup of traditional careers from data analysis, economics, statistics, computer science and others.
But it goes beyond collecting and analyzing data. It's a job for the curious, for the intuitive and for those who like to not just solve problems but figure out the problem. It's part science, part art.
The rise of data science is due to the explosive growth of data collection — or big data — and the need for companies to make sense of the mishmash of new types of data from smartphones, images, human behavior and even handwriting.

Healthcare Analytics Trends for the New Year
Analytics continues to bring dramatic change to the healthcare industry in the United States and other countries, offering advances and challenges for the year ahead. Following are 10 trends to chart in 2016.
2016 Analytics Trends to Watch For
My view of the world is shaped by where I stand, but from this spot the future of analytics for 2016 looks pretty exciting! Analytics has never been more needed or interesting.
Temptation Bundling at the Gym
Lack of motivation may also play a large role in the reason why 68.8 percent of Americans are overweight or obese.
So are we all screwed? Or is there a way to keep motivation consistently flowing?
The process pairs two activities—one you should do, but avoid; and one you enjoy, but isn’t necessarily productive, explains lead study author Katherine Milkman, associate professor of Operations, Information, and Decisions at The Wharton School.
High Debt Load Tough for Union Negotiators
Why are unions having a tough time in this country? One reason is that companies are getting leverage. A recent study found that companies with a higher debt load were less likely to experience a strike during contract negotiations, particularly at companies with large unions, worse financial prospects, or underfunded pension plans. Some companies seem to anticipate this and load up on debt before contract negotiations, whereas companies that didn’t do this and experienced a strike subsequently add a ton of debt, particularly if the union won the strike. The debt gives the company a bargaining advantage by limiting how much earnings can be shared with workers vis-à-vis lenders, and often takes the form of stock buybacks, to avoid bringing money into the company.
Bed Net Plan for Underfed Kids Curbs Malaria Deaths
Giving extra bed nets to children weakened by lack of food could significantly curb child deaths from malaria, according to a mathematical model revealed last month.
A study published in the Malaria Journal found that distributing insecticide-treated bed nets and supplementary food to undernourished children aged from six months to five years could help prevent their deaths from malaria. This is because children with malnutrition are much more likely than healthy children to succumb to the disease, the paper states.
The model proposed by Milinda Lakkam and [former Operations Research Editor-in-Chief and INFORMS Fellow] Lawrence Wein, two mathematicians at Stanford University in the United States, shows that such targeted distribution of insecticide-treated bed nets is better at reducing malaria deaths than random distribution. In one tested scenario, where malaria transmission was pegged as seasonal and intermittent, the distribution of bed nets specifically to undernourished children achieved a 69 per cent reduction in malaria mortality.
Detecting Sick Milk in China
In 2008, thousands of children in China fell ill after drinking milk that had been adulterated with the chemical melamine.
This scandal inspired Liying Mu, University of Delaware assistant professor of operations management, to study ways to eliminate this dangerous and common problem.
“Milk adulteration, such as by adding, water, detergent or starch to milk, has been widely reported in many developing countries,” Mu said. “What are the reasons for those adulterations? And how can we solve the problem?”
In two papers published in top journals Management Science and Production and Operations Management, Mu’s team found three key reasons behind the milk adulteration problem, as well as a number of creative solutions.
Portfolios and Their Debt to an O.R. Nobel Winner
During WWII, academics developed “Operations Research” techniques involving statistics and linear programming to hunt enemy submarines, supply troops on the ground and deliver ordnance to targets. Soon after the war ended, Operations Research academics began to apply their methodologies to investing. In 1952 Harry Markowitz, a graduate student at the University of Chicago, published a paper on portfolio selection in the Journal of Finance. Markowitz’s quantitative approach to investment theory was radically different from the conventional stock market wisdom at the time, which focused on picking winning stocks and concentrating stock holdings to maximize return. Investors knew that holding stocks meant taking risks, and they were led to believe that the only way to reduce risk was to become more competent at picking stocks. Some investors were following the advice of Gerald M. Loeb, the co-founder of brokerage firm E.F. Hutton, who wrote “once you obtain competency, diversification is undesirable.” Markowitz’s work along with others gave birth to what is now known as Modern Portfolio Theory (MPT). MPT provided investors quantitative ways to reduce risk and optimize their return.
How to Improve Decision Making in Supply Chains
David Simchi-Levi, MIT Professor, INFORMS Fellow and Former Editor-in-Chief of Operations Research (INFORMS Journal)
The ability to understand a combination of historical behavior, market conditions and future needs drives decision making. New analytic capabilities that combine machine learning and optimization can take into account historical characteristics and competitor behavior to determine future demand that will allow optimization for the best results - such as profit, market share or revenue.
Examples of decisions where this approach can be used is assortment, pricing, sourcing strategies for new products, predictive maintenance using process sensors.
New light on top sports accomplishments: Liberatore et al:
Peyton Manning could break Brett Favre’s NFL record for most career passing yards if he throws for at least 284 yards against the Indianapolis Colts on Sunday.
But in the universe of sports’ greatest feats, is this record really that impressive?
A study published in October in the “Journal of Sports Analytics” suggests otherwise. The study, by Villanova professors Matthew Liberatore, Bret Myers and Robert Nydick and Temple professor Howard Weiss, attempts to quantify and rank the best MLB, NBA, NHL and NFL records of all time. It includes single-game, season, career and consecutive-streak records.
The best record of all belongs to Barry Bonds—but it’s not for hitting home runs.
