Wilczek appointed founding director of the Tsung-Dao Lee Institute in China

September 20, 2017

Nobel laureate Frank Wilczek, a Distinguished Origins Professor at Arizona State University, was appointed founding director of the Tsung-Dao Lee Institute at the Shanghai Jiao Tong University in Shanghai, China, on Sept. 14.

The institute was set up with the direct involvement of Xi Jinping, president of China, and the decision to nominate Wilczek was made at the government level. $man in front of screen with a fractal on it$ ASU Professor Frank Wilczek lectures to freshmen at School of Physics and Astronomy at Shanghai Jiao Tong University.

Tsung-Dao Lee Institute will be the first institution built at a new Science City, located centrally in the Pudong area between downtown and Pudong airport. The total area of Science City is 94 square kilometers, and it will eventually contain eight research facilities. The institute aims to be a world-leading center for pure science and will have both theoretical activities and experimental activities. It will conduct public outreach and pursue technological ventures, which include public lectures, summer schools, and science, art and interdisciplinary ventures.

At the inauguration event, Zhongqin Lin, president of Shanghai Jiao Tong University, discussed the future opportunities and national level goals of the university: “This is one of the most exciting developments in China,” he said.

The birth of the institution began when Tsung-Dao Lee donated his archives — including a Nobel medal — to Shanghai Jiao Tong University from 2009 to 2012. In 2014, he wrote a personal letter to President Xi and proposed a creation of a unique scientific institution in Shanghai. The inauguration of Tsung-Dao Lee Institute took place on Nov. 28, 2016, with encouragement and support from President Xi.

Wilczek is also chief scientist at the Wilczek Quantum Center, a theory group at Shanghai Jiao Tong University, which is aligned with (but independent of) Tsung-Dao Lee Institute.

ASU team takes cyberbullying app public

Washington, D.C. West campus

September 20, 2017

BullyBlocker an interdisciplinary effort, goes beyond abilities of other apps by combining risk factors with keywords to alert parents

Last December, as other teens were looking forward to the holiday season and planning outings with friends and family, Houston-area high school student Brandy Vela was feeling so overwhelmed by online harassment that she held a gun to her chest and pulled the trigger.

Vela's death is an extreme example of what can happen as a result of cyberbullying, but a 2016 paper co-authored by Yasin Silva, associate professor of computer science at Arizona State University, cites a statistic that more than half of adolescents have been bullied online.

Just this month, Silva and his New College of Interdisciplinary Arts and Sciences team of faculty and students announced the public availability of BullyBlocker, a smartphone application that allows parents and victims of cyberbullying to monitor, predict and hopefully prevent incidents of online bullying.

The first version of the app is currently available for free in the Apple app store, and the ASU team has received a nearly $300,000 grant from the National Science Foundation to continue research and development of subsequent versions.

While there are other cyberbullying applications available, BullyBlocker is different in that it is the first and only application so far to do more than just flag potentially harmful posts and comments.

Existing apps comb through content on a person’s social-media profile looking for keywords or phrases that could indicate bullying and alert the user of the app — the user of the app can be a parent, guardian or even the victims themselves.

“We are going beyond that,” Silva said. “That’s just step number one in our process.”

BullyBlocker not only identifies those kinds of threats, it combines that information with risk factors (also called states of vulnerability) that have been shown to increase the probability of bullying, such as whether a person has recently moved schools, their socioeconomic status or their race. The app calculates the probability that an adolescent is being bullied based on keywords and risk factors, then alerts the app user — who most likely would be a parent or guardian, helping them to be aware of what is happening in their child's life.

“We’re trying to use a more holistic approach to really consider all the different signs and factors that might be involved in cyberbullying,” Silva said.

Doing so has been a truly interdisciplinary undertaking. When the idea for BullyBlocker came about in 2013, Silva quickly realized that in order to have the best, most accurate model, the application would need input from areas other than applied computing.

“From the computer science side, we are experts in terms of data analysis and creating computational models and so on,” Silva said. “But we didn’t know much initially, and I think still our understanding is limited, in terms of what is the nature of cyberbullying? How does it happen? And when it happens, what are the factors involved?”

So he approached Deborah Hall, ASU assistant professor of psychology, who was excited to collaborate. Hall and her psychology students were able to provide insights Silva and his computer science students may not have considered.

At a recent BullyBlocker meeting, the team was discussing the risk-factors portion of the app. They were considering adding sexual orientation to the list, as many LGBT youth experience a higher rate of bullying than their heterosexual peers. Hall pointed out that there could be an issue if the LGBT youth had not come out to their parents, who may be operating the application.

“With each meeting, my knowledge of the computer science and applied computing side of things is getting incrementally larger,” Hall said. “But what attracted me to the project in the first place … was the potential to take some of the research literature and findings from psychology that have been published in more traditional academic outlets and find a way to incorporate them in a meaningful way that will have some real-world consequences.”

BullyBlocker came about from the desire to make a positive social impact through use-inspired research. More than one of the student team members have been supported by NCUIRE, New College’s Undergraduate Inquiry and Research Experiences program.

One of them, Rusty Conway, said that along with giving him real-world experience that has helped build his computing skills, working with the BullyBlocker team has been meaningful because “it’s going to have some kind of social impact that I can be a part of and hopefully be beneficial to people.”

The first version of BullyBlocker that is available now works in conjunction with Facebook. Future iterations are in development to incorporate other social-media platforms like Instagram and Twitter. Funding from the NSF grant will be helpful to that end, Silva said, as well as making further interdisciplinary collaboration possible.

“I really enjoy watching the interactions and how [we all] grow in understanding of relevant theories,” he said. “I see the potential of even greater impact coming out of these collaborations.”
