The drawbacks of data transparency Jake Moser News Editor

The Public Library of Science announced Monday that researchers must be more transparent with their findings. The nonprofit publisher reversed its data-sharing policy and will now require researchers to provide their data immediately upon publication. Data, according to the PLOS website, include spreadsheets, sequence reads, verbatim responses from qualitative studies, software code, image files used to create figures and datasets. Eric Stone, associate professor in the College of Sciences, said the idea of data transparency is beneficial overall, but there are some potentially harmful implications. Stone, who has published research in PLOS journals and many other publications, said the new datasharing policy isn’t unfamiliar to the field of biology, where he does most of his research.

“We’re just going to have to figure out the best way to do it so that everybody benefits.” Emily Meineke, graduate student in entomology

“The PLOS issued a pretty strong message, but it’s not that different from how [biology researchers] feel,” Stone said. “Typically, what we’re supposed to do is make data freely available when we publish. If our project is federally funded, it’s a mandate. We’re expected to make data publically available, and there’s nobody forcing us to do it before the fact.” For publications that aren’t completely open-source, if someone wants specific data from a research article, they will either find them in supplementary material or request

them from the author directly, Stone said. Now, PLOS wants everything to be available immediately. “Researchers are used to this concept, but not with this degree of stringency and dogma,” Stone said. However, requiring data transparency can lead to privacy issues when researchers use human medical data, for example. According to Stone, even if this type of data is summarized, it can still present a problem if made publically available, and the privacy of research participants has been compromised in the past. “Would you want your own DNA sequence out there and available? I personally wouldn’t,” Stone said. “If someone was doing research involving medical records, should they make it publically available? No one thinks they should.” “No one” includes the PLOS, which lists personal medical re-

Researchers at N.C. State recently developed a breakthrough in smart sensor technology by combining vanadium dioxide with an advanced computer chip. The discovery allows the material to have a wide range of applications, some geared toward military use. Jay Narayan, a professor in material science and a senior author of the paper about the smart sensors, said the researchers’ work will improve upon existing technology. “The military is already talking to us,” Narayan said. “They have a device that doesn’t work as well, and I think with this device they will have considerable improvement.” According to Narayan, the smart sensor will help the military develop better infrared sensors because the current models are too bulky. “A soldier has to carry a computer with a sensor that is hardwired by a physical wire,” Narayan said. “Our discovery has put all of this in one

chip, so the computer and the sensor are together. Sensing, manipulation and responding are all on a single chip.” In addition to being used as an infrared sensor, the material can also create something called a smart window. When heated, the material becomes highly reflective and blocks incoming sunlight. “You can set the temperature above which you don’t want the sunlight to come in and, through the optical transmission, it goes from transparent to highly ref lective,” Narayan said. The smart window technology can be applied for everyday use, not just military use, and can perhaps eliminate the need for window blinds. “A big problem here at Centennial Campus is that when we get a lot of sunlight, it heats up the room,” Narayan said. “If you had a smart window, you could set it to 70 degrees, and then the sunlight would be reflected back.”

Comcast-TWC merger could improve service Estefania Castro-Vazquez Assistant News Editor

The proposed merger between Comcast and Time Warner Cable has received a lot of critical attention from both customers of both companies as it could potentially alter prices and quality, but not all outcomes may be detrimental to Raleigh residents, according to Michael Walden, William Neal Reynolds Distinguished Professor & Extension Economist at N.C. State. The merger would make Comcast the largest provider of cable and internet services in the East Coast,

according to an article in The New York Times. Customers are concerned with the Comcast-Time Warner merger due to fears of limited competition that could potentially lead to higher prices, Walden said. “If there are no viable competitors, there’s not much motivation to do things better and to innovate,” Walden said. However, Walden said he has heard that in comparison to Time Warner, Comcast has better technology, faster speeds and more innovation techniques, and if that’s

Speaker stresses link between technology, financial success Jacob Fulk Staff Writer

“How many of you want to be a geek?” said Victor Fetter, CIO of LPL Financial, to about 25 people during a lecture on Centennial Campus Tuesday night. Fetter’s presentation was titled “Recognizing the Power of Technology to Unlock Value and Enable Dreams,” and during his speech, Fetter discussed emerging technologies and their applications in the world of finance. The act of “enabling dreams,” is exactly what LPL Financial strives to do, Fetter said. As a statement of LPL Financial’s purpose, Fetter said that LPL Financial wants to help millions of Americans through independent financial advice. Concerning what sets LPL Financial apart from other financial consulting firms, Fetter said his

company’s advisors provide experience as well as personal advice and conversation to get to know their patrons. Much of Fetter’s presentation emphasized the adaptation of the financial world to modern technologies. Fetter challenged those in the audience to question how popular social media applications, such as Facebook and Whatsapp, make money. He said that interesting ideas only have value when they have a practical or problem-solving application. “Technology for technology’s sake is useless,” Fetter said. “Technology has to have an endgame in mind.” According to Fetter, if you don’t think about the applications of a technology while creating it, then you’ve missed the mark. Fetter said that innovation is one
