A first-person camera, placed at the person’s head, captures our visual sensorimotor object interactions. Can a single first-person image tell us about our momentary visual attention and motor action with objects, without a gaze tracking device or tactile sensors? To study the holistic correlation of visual attention with motor action, we use the concept of action-objects—objects that capture p...

Theoretical models suggest that social networks influence the evolution of cooperation, but to date there have been few experimental studies. Observational data suggest that a wide variety of behaviors may spread in human social networks, but subjects in such studies can choose to befriend people with similar behaviors, posing difficulty for causal inference. Here, we exploit a seminal set of l...

On an everyday basis, we communicate with one another using various technological media, such as text messaging, social networking tools, and electronic mail, in work, educational, and personal settings. As a consequence of the increasing frequency of use and importance of computer-supported interaction, social scientists in particular have heeded the call to understand the social processes inv...

We develop predictive models of pedestrian dynamics by encoding the coupled nature of multi-pedestrian interaction using game theory, and deep learning-based visual analysis to estimate person-specific behavior parameters. Building predictive models for multi-pedestrian interactions however, is very challenging due to two reasons: (1) the dynamics of interaction are complex interdependent proce...

C ontinuing progress in microelectronics has allowed the embedding of sensing, processing, and wireless communications capabilities in familiar physical objects. This enables the creation of smart environments, where communication and computation technologies facilitate interactions between people and their surroundings, instead of just person-to-person or person-to-server communication. In a c...

Many problems in nature can be conveniently framed as a problem of evolution of collective cooperative behaviour, often modelled resorting to the tools of evolutionary game theory in well-mixed populations, combined with an appropriate N-person dilemma. Yet, the well-mixed assumption fails to describe the population dynamics whenever individuals have a say in deciding which groups they will par...

Abstract Several studies recommend language-based strategies for communication with persons living dementia. Language-based improve coherence, clarity, reciprocity, and continuity of interactions. Person-centered (PCC) are the gold standard, including facilitation, recognition, validation, negotiation. Only one study has examined overlap between PCC in long-term care. Little is known about whic...

Physician racial bias can negatively affect Black patients' reactions to racially discordant medical interactions, suggesting that racial bias is manifested in physicians' communication with their Black patients. However, little is known about how physician racial bias actually influences their communication during these interactions. This study investigated how non-Black physicians' racial bia...

The array of ethical issues facing the food industry is extensive. It includes fair and just treatment to food industry employees, especially as disproportionate numbers of minorities take jobs in food processing and food service. Issues of food distribution and hunger continue to be important. In the calendar year 1992, however, these issues pale in comparison to those raised by food safety an...
