At first glance, many of the children at a nutrition treatment center in São Paolo look anything but hungry. Most, in fact, are overweight. But they’re also malnourished – a troubling sign, experts say, of Brazil’s move from a traditional diet heavy on rice, beans, protein, fruits, and vegetables to one dominated by fast and processed food. A Kellogg Institute faculty fellow and visiting guest scholar from Brazil are now combining technology, psychology, and the social sciences in an effort to combat child malnutrition in the South American country.
Anthropologists have debated for decades whether humans living in tribal communities thousands of years ago were more or less violent than societies today. Researchers at the University of Notre Dame wonder if the question of more or less violence is the wrong one — what if it’s a matter of scale?
A paper by graduate students Maria Glenski, Corey Pennycuff, and Prof. Tim Weninger from the University of Notre Dame that was published via IEEE Transactions on Computational Social Systems suggests that 73 percent of the users that vote on a particular Reddit post haven’t actually clicked through to view the content.
Society has always used materials as the “building blocks” for civilization. Roads, homes, electronics and medicines — everything was fashioned from available substances. Today researchers are creating totally new materials for a variety of applications. More precisely, they are designing materials with specific properties to address distinct tasks. Engineers and scientists are not only creating these novel materials, but they are also documenting their processes and the results, along with related patents and publications.
Aastha Nigam, a doctoral student in the Department of Computer Science and Engineering, placed second in the graduate division of the Association for Computing Machinery’s (ACM) Student Research Competition (SRC) held Oct. 4-6 during the recent Grace Hopper Celebration (GHC) in Orlando, Fla.
The Army Research Office (ARO) has Prof. Dong Wang and Prof. Tim Weninger with Young Investigator Program (YIP) awards for 2017. The ARO YIP awards are among the most prestigious honors awarded by the Army to outstanding researchers beginning their independent careers. The goal of this program is to attract outstanding early career faculty to pursue fundamental research in areas relevant to the Army, to support their research in these areas, and to encourage their teaching and research careers.
Alumni Yuxiao Dong receives Honorable Mention for the 2017 Doctoral Dissertation Award at KDD'17 for his dissertation "Computational Lens on Big Social and Information Networks". PhD Advisor: Prof. Nitesh Chawla.
Network-based representation has quickly emerged as the norm in representing rich interactions in complex systems. For example, given the trajectories of ships, a global shipping network can be constructed by assigning port-to-port traffic as edge weights. However, the conventional first-order (Markov property) networks thus built captures only pairwise shipping traffic between ports, disregarding the fact that ship movements can depend on multiple previous steps. The loss of information when representing raw data as networks can lead to inaccurate results in the downstream network analyses. We have developed Higher-order Network (HON), which remedies the gap between big data and the network representation by embedding higher-order dependencies in the network. This project website shows how existing network algorithms including clustering, ranking, and anomaly detection can be directly used on HON without modification, and influence observations in interdisciplinary applications such as modeling global shipping and web user browsing behavior. Video demo, source code in Python and testing data are also available.
In humans and other mammals, the cerebral cortex is responsible for sensory, motor, and cognitive functions. A new study shows that the global architecture of the cortical networks in large-brained primates and small-brained rodents is organized by common principles. However, primate brains have weaker long-distance connections, which could explain why large brains are more susceptible to mental illnesses including schizophrenia and Alzheimer's disease.

Mobile money platforms are key in promoting cohesion and reducing barriers to social inclusion, a new study by three American university researchers shows. Professor Sibel Kusimba of the American University in Washington D, Nitesh Chawla and Yang Yang of the University of Notre Dame, Indiana, say the platforms help reinforce pre-existing forms of emotional support and social relationships — like in the case where family and friends bail out each other.
In an ageing world, a growing market for technological innovations for the elderly is giving Logan a Run for his money.
Fitbits, the activity tracking wristbands, have become a popular identifying feature of Notre Dame freshmen this year. Five hundred Fitbit-wearing freshmen are participating in a study called NetHealth, which aims to explore the relationship between social networks and health.
Cellphones, any parent can attest, play a central role in the lives of college students. Studies show that nearly all college students own a cellphone, and most of those students use text messaging as their main form of communication. Researchers from the University of Notre Dame used the centrality of cellphones in college students’ lives to delve deep into students’ usage habits and how their social networks affect their everyday lives.
New technology and old folks aren't known to have a good connection, but a new app developed by researchers at Notre Dame is bridging that gap. eSeniorCare is being used by a group of residents at Heritage Place to better manage their health needs.
