The inspiration for his co-authored research paper, Brad Greenwood said, materialized rather organically.
“I was in the backseat of an UberX vehicle,” Greenwood said, “and I wrote myself a cell phone note: ‘Call Sunil about writing an Uber paper.’”
According to research by Greenwood and Sunil Wattal, professors at Temple University’s Fox School of Business, the introduction of UberX, a low-cost, ride-sharing service, has led to the reduction of alcohol-related vehicular fatalities in California.
Their research findings have been featured widely in mainstream national and international media outlets, including Newsweek, Fox News, Forbes, Canada’s Globe and Mail, Britain’s Daily Mail, Quebec’s La Presse, the Washington Post, the Los Angeles Times, Tech Times, and others. Their working paper, titled, “Show Me The Way To Go Home: An Empirical Investigation of Ride Sharing and Alcohol Related Motor Vehicle Homicide,” is under review for publication in an academic journal.
Uber is a mobile-app-based service through which consumers can call for transportation to and from any destination. The system requires credit card registration prior to usage, which means no physical money changes hands in the transaction. Available in more than 50 countries, Uber’s popularity has soared recently, and an August 2015 report from Reuters suggests that Uber’s bookings in 2016 could exceed $26 billion.
Greenwood and Wattal are believed to have written the first academic paper investigating the effects of Uber on reducing alcohol-related vehicular homicides.
“The issue is timely and fresh. Everyone is talking about Uber,” said Wattal, an Associate Professor of Management Information Systems (MIS) at Fox.
“There was evidence that Uber could be linked to such decreases in fatalities, but the question as to whether it could be tied together rigorously, and under certain circumstances, wasn’t yet known,” said Greenwood, an Assistant Professor of MIS.
Using publicly available data obtained from the California Highway Patrol’s Statewide Integrated Traffic Report System, for a period between January 2009 and September 2014, Greenwood and Wattal analyzed reports that included the blood-alcohol content of the driver, contributing factors like weather, speed, and environmental factors, and the number of parties involved in the accidents. Greenwood and Wattal said they chose to review California’s data because Uber is headquartered in San Francisco, and the ride-sharing service has been available in that state longer than in any other.
In their research, they found that alcohol-related deaths decreased by an average of 3.6-5.6 percent in cities where UberX service, the least-expensive service offered by Uber, is available. They also found limited evidence of change in conjunction with the use of Uber Black, the most-expensive service, which requires a luxury vehicle.
Other findings from the co-authored research paper include:
- The effects of UberX on the number of alcohol-related fatalities took hold, on average, from nine to 15 months following Uber’s introduction to a particular city, “after Uber has built up a network of customers and drivers in that marketplace,” Greenwood said.
- There was little to no effect in periods of likely surge pricing, a system that allows Uber to increase the cost of the services rendered dependent upon the consumer demand.
- There was no effect between Uber and overall deaths, indicating that the entry of Uber is not making roads more dangerous for sober people.
For Greenwood, who has previously studied the societal benefits of technologies, and Wattal, who has researched online crowdfunding and peer-to-peer economies, their research interests overlapped, which made this project a natural choice on which they could collaborate. Unsurprisingly, their Uber research, which was independently funded, has generated requests for follow-up studies.
“We could try to replicate this study in the context of other states to see if the data is robust,” Wattal said, “but that could take considerable time, given that Uber is not available everywhere and that data is not as readily available in other states.”
“The options are endless for this type of work,” Greenwood said.
Google “big data,” and the first search result returns the word, “dangerous.”
The irony of using a big data factory to discover the risks of its own data was not lost on researchers and experts attending the Privacy in an Era of Big Data workshop, funded by the National Science Foundation (NSF) and hosted by the Fox School of Business and Temple University’s Big Data Institute.
“Big data” is loosely defined as the collection and analysis of large data sets of complex information. As the scope of collected data increases, there is a significant need for advanced analytic techniques and the development of new methods of investigation. Temple’s Big Data Institute was established to harness the full potential of big data and enable further research on the subject with an interdisciplinary approach by bringing together seven related research centers across the university and the Fox Chase Cancer Center.
Co-founder of the Institute Dr. Paul A. Pavlou, Chief Research Officer and Associate Dean of Research, Doctoral Programs, and Strategic Initiatives, along with Dr. Sunil Wattal, Director of the Center on Web and Social Media Analytics and Associate Professor of Management Information Systems, were awarded a grant from the NSF to further their investigation into unexplored links between big data and privacy.
“This is a topic that’s on everyone’s minds, and we’re here to get some useful insight on it,” Wattal said.
The workshop, held April 22-23, was a part of a weeklong event to encourage big data research from industry, government, and academia on the future of big data and privacy. The goal of the workshop, Pavlou said, was “to create a forward-looking research agenda into the future of big data.”
A priority for attendees was establishing the balance of big data with privacy rights, in order to improve national security and further develop consumer marketing. Dr. Thomas Page, Technical Director for Core Infrastructure & Cloud Repositories at the National Security Agency, represented the government perspective on big data, with a keynote presentation.
“There’s a moral responsibility in this space. We’re doing this on behalf of the American people,” Page said.
Page called for a new focus when discussing big data. “Big Smart Data,” he said, avoids unnecessary or intrusive information from reaching analysts, and allows new public policy to be enacted that balances personal privacy and national security concerns.
Page’s keynote address raised concerns of a “zero sum game,” wherein consumers trade privacy for national security. Christina Peters, Chief Privacy Officer at IBM, noted that she believes the two are not equivalent. Citing instances of security breaches at Target and Home Depot, she indicated how a history of misuse or neglect has risked consumer information.
Hal Varian, Chief Economist at Google, discussed the trust contract held between consumers and big data collectors. He argued that big data factories have the most to lose. “Search engines have a lot more to lose than a human. When computers screw up they screw up big,” Varian said.
Google’s top search results for “how do I know” are: “if I’m pregnant,” “if I’m gay,” and “if I have AIDS,” all of which, Varian said, demonstrate Google’s desire to not only share a vast amount of information, but to also take seriously its responsibility as an online confidante.
“Search engines are the biggest privacy enhancers in the world. People won’t ask these questions to their lawyer, doctor, parents, or priest. This is the first time you can get this type of answer from a non-human,” said Varian, who also served as the featured keynote speaker at the Frederic Fox Lecture Series April 23, another event during Big Data Week.
Varian explained that the intended use of big data is to educate consumers on the difference between privacy and security. Since privacy is the restricted use of personal information, a responsibility of big data should be to protect the security of the data and manage the risks associated with personal data analytics.
A closing comment from the first day of the workshop was the idea that “big data is the new bacon,” as presented by Lael Bellamy, Chief Privacy Officer at The Weather Channel. Her support of improved data collection and consumer intelligence reinforced the notion that although big data is trending, it’s been around for a long time.
“It’s possible everyone can benefit from the Big Data revolution,” said Carnegie Mellon University professor Dr. Rahul Telang.
The bar graph is dead.
It’s a bygone relic of an era intimidated by 1.28 billion Facebook members and 3 billion computer users globally. These numbers are not as daunting as they once were; rather, they are now the tools used to determine anything from favorite food to political preference.
This is big data, the new face of statistical and computational analysis.
Big data is the collection of data sets so large that it is difficult to process them with traditional methods. As the volume, velocity and variety of these sets increases, so does the need for informed analytics.
The Fox School of Business created the Big Data Institute for just this purpose.
In existence for more than a year, and with the assistance of seed money provided by Temple University Provost Hai-Lung Dai, the Big Data Institute strives to blend several programs and encourage natural synergies among big data researchers, students and firms, while seeking to become a global leader in research, education, industry practice, and technology transfer of big data.
For Dr. Paul A. Pavlou, Senior Associate Dean of Research, Doctoral Programs, and Strategic Initiatives at the Fox School of Business, the Institute represents a year of work supporting students and professors engaged with large data.
“The amount of data created in just an hour or minute is tremendous. We need new techniques and approaches to make sense of this data,” Pavlou said.
The Institute has five centers with individual specializations that include big data usage in mobile analytics, social media, health sciences, oncology research, statistics and biomedical informatics. These centers have used big data to connect brain imaging to successful advertisements, to use technology to create vast amounts of DNA for clinical study, and, in the School Tourism Hospitality and Management, to decrease dissatisfaction in the leisure industry, among other research projects.
“One of the unique advantages we have is that the Statistics department is housed in Fox. We try to leverage that to have different conversations,” Pavlou said.
The Institute and its centers are funded by data enthusiasts from Temple University, the federal government, affiliated firms and commercial groups, as well as start-ups the Institute helped get off the ground. With the aid of these associates, and partners in the private sphere, the Institute seeks to continue its research into cutting-edge data analysis.
In its pursuit of this goal, the Institute’s Center for Web and Social Media Analytics has capitalized on the data generated each minute from the 74 percent of adults using social media.
For Dr. Sunil Wattal, Associate Professor of Management Information Systems (MIS), this data is critical. “There is not a whole lot of awareness of what firms can do with social media,” Wattal said. “The Center provides firms with a way to quantify the value of social media and use the data to derive some interesting insights about their business.”
The Center logs onto social media to help firms such as Aerospace to understand consumer tendencies at the microscopic level. Combing through Twitter or flicking through Instagram, the Center decrypts consumer preferences for the latest fitness craze to political party affiliation. This data is then synthesized into something that anyone, from pollsters to yogis, can use to further their goals.
A key area of research, said Wattal, is how a crowdfunding organization can convince more people to donate to campaigns. Chief among the Center’s findings is that, contrary to the belief that Internet popularity grows exponentially, the more popular a campaign, the less likely it is to receive more funding. Working with a particular company, the Center has proposed design changes to combat this issue.
“There’s a community that gets created on these sites, and you can measure how people influence each other,” said Wattal.
In 2015, the Center will use funds received from the National Science Foundation (NSF) to host a big data and privacy conference, bringing together federal agencies, online giants such as Google, and interested parties to discuss personal privacy in the Big Data age.
To keep students abreast of the latest in data analysis, the Fox School’s MIS department has introduced its newest university-wide course, Data Science. It is available to all students and has allowed business students to improve their data usage in the business world.
“We’re constantly surrounded by data. If you can get the average employee to take this data and get some insight on their own you can give them an advantage over the rest,” said Dr. David Schuff, Associate Professor of MIS and instructor for the Data Science and Data Analytics courses.
Schuff said he begins with the basics – teaching business majors and minors in his Data Analytics course how to use data-mining software, like SAS Enterprise Miner, to examine data and identify its pertinent characteristics.
“We want them to be able to look at cause-effect relationships in business data and use some basic tools to analyze that data and use the results to make better decisions,” Schuff said.
Using the basic skills Schuff teaches, students can use data to examine consumer preferences, such as using sales receipts to predict which goods are bought in tandem and how strategic sales can maximize profits. Broadening the scope, if politicians want to know a Facebook friend’s electoral value, they need someone who can use big data to decipher the sentiment behind a Facebook post. For Schuff, this person is someone who is, “comfortable with data,” and can fuse tools gleaned in business classes to decode the human psyche.
Data professionals “know what you can do with data and so they know how to support the marketing function. These people aren’t going to be just data scientists, …but business people who are working with data,” Schuff said.
Schuff aims for his students to move beyond the bar graph- and pie chart-models to create and analyze more sophisticated visualizations to better integrate data in their professional lives. These students get hands-on experience using SAS products, as well as Tableau software, both of which are currently used in the analytics industry.
“We really want people to touch the tools they would be using in industry so they can speak from experience,” Schuff said.
The National Science Foundation (NSF) has awarded Temple University’s Fox School of Business with a $50,000 grant, with which the School will fund a workshop workshop is to bring together experts in the domain of big data and privacy to develop a research agenda for better understanding and promoting privacy in an era of big data. The “Privacy in an Era of Big Data Workshop”(please link to fox.temple.edy/nsfworkshop) will take place at the university on April 22 and 23 of this year. Government officials, industry leaders, and notable academics will meet to discuss privacy issues surrounding big data, and to develop a forward-looking agenda for research on the legal, technological, social, behavioral, economic, and broader implications of Big Data and Privacy in academia, industry, and government.
Dr. Paul A. Pavlou, the Milton F. Stauffer Professor, as Principal Investigator, and Associate Professor of Management Information Systems Dr. Sunil Wattal, as Co-Principal Investigator, received the NSF grant. The objective of the NSF workshop is to demonstrate the merits in the pursuit of the potential for big data while respecting privacy rights.
In the proposal, Pavlou and Wattal argued that there are “unexplored links” between big data and privacy, and that the potential exists for breaches of privacy, particularly by corporations, malicious individuals or governments. The workshop, Pavlou and Wattal said, would unite individuals from multiple disciplines in an attempt to promote a “forward-looking agenda.”
“People often have very little control over the collection process, in terms of knowledge about what information is being collected and stored about them,” said Pavlou, a Co-Director of Temple’s Big Data Institute and the School’s Chief Research Officer. “They also are unaware of who has access to the information, and for what purpose the information will be used.
“Finding solutions to these big day and privacy problems must become a priority for this generation of interdisciplinary research.”
The NSF workshop will cover: the tradeoff between the benefits of big data and privacy protection; the legal, public policy and regulatory issues on privacy; privacy protection technologies; and social, behavioral and economical approaches to encouraging individual privacy practice.
Slated to take place in late Spring 2015, the workshop will be open to all centers that operate in conjunction with Temple’s Big Data Institute. Additionally, select global big-data experts from academia, industry, and government will be invited to attend. A date for the workshop has not yet been finalized.
