Since publication of Unequal Treatment by the Institute of Medicine in 2003, there has been a growing recognition of the role of provider implicit racial bias in patient care. Provider implicit racial bias has been consistently negatively associated with both care satisfaction and provider trust among racial/ethnic minority patients. This suggests provider implicit racial bias likely manifests through their communication behaviors, which in turn may offer a means of addressing racial disparities in healthcare and ultimately in health. However, identifying provider communication behaviors that mediate the links between provider implicit racial bias and patient outcomes is challenging. In this paper, we argue that identifying these provider communication behaviors requires (1) taking into account findings from social psychology research of implicit racial bias and (2) incorporating the perspectives of racial/ethnic minority patients into patient-provider communication research. We discuss the utility of mixed methods research designs as a framework for resolving this complex scientific question. Research that draws on social psychology research of implicit racial bias and incorporates the racial/ethnic minority patient perspectives can inform the development of communication skills training programs for students and residents in various healthcare fields. Such programs are one element of a broader effort to reduce racial/ethnic disparities in healthcare. [ABSTRACT FROM AUTHOR]

This paper develops a principled approach to accurately identify interesting places in a city through social sensing applications. Social sensing has emerged as a new application paradigm, where a crowd of social sources (humans or devices on their behalf) collectively contribute a large amount of observations about the physical world. This paper studies an interesting place finding problem, in which the goal is to correctly identify the interesting places in a city. Important challenges exist in solving this problem: (i) the interestingness of a place is not only related to the number of users who visit it, but also depends upon the travel experience of the visiting users; (ii) the user's social connections could directly affect their visiting behavior and the interestingness judgment of a given place. In this paper, we develop a new Social-aware Interesting Place Finding Plus (SIPF+) approach that addresses the above challenges by explicitly incorporating both the user's travel experience and social relationship into a rigorous analytical framework. The SIPF+ scheme can find interesting places not typically identified by traditional travel websites (e.g., TripAdvisor, Expedia). We compare our solution with state-of-the-art baselines using two real-world datasets collected from location-based social network services and verified the effectiveness of our approach.

The paper establishes the exponential stability of a micropolar thermoelastic homogeneous and linear body with frictional dissipation and thermal conduction of hyperbolic type, allowing for second sound. Existence and uniqueness are proved within the semigroup framework and stability is achieved thanks to a suitable Lyapunov functional. [ABSTRACT FROM AUTHOR]

The carbon fiber/polymer matrix interphase region plays an important role in failure initiation and accurate modeling techniques are integral to study the effects of this complex region on the composite response. In composites infused with nanoparticles such as carbon nanotubes (CNT), the interphase region is more complex due to the presence of multiple constituents and their interactions with each other. An atomistic methodology to simulate the constituent interphases in carbon fiber reinforced CNT/epoxy nanocomposites is presented in this paper. The interphase model consisting of voids in multiple graphene layers enable the simulation of physical entanglement between the polymer matrix and the irregular carbon fiber surface. The voids in graphene layers are generated by removing carbon atoms and hydrogenating the end carbon atoms, which better represent the roughness of the carbon fiber surface. The epoxy curing studies and the response of fiber/matrix interphase under mechanical loading are investigated through molecular dynamic (MD) simulations with appropriate classical/harmonic and bond order-based force fields. Furthermore, the atomistic force-displacement behavior is also extracted to formulate a traction-separation law for interface cohesive zone models. The cohesive behavior determined from molecular models is parameterized in equations that can be integrated with an atomistically informed multiscale modeling framework. [ABSTRACT FROM AUTHOR]

Abstract: In this paper, I introduce the hypothesis that there are two levels of mindreading. The first level refers to automatic-preconceptual phenomena that specify a primitive understanding of another person''s mind. It is based on early-imitation, action and emotion recognition. The second level of mindreading is conceptual and voluntary. It is based on intentionality, empathy, and higher depths of reasoning. The activities in both levels are generated by internal simulative mechanisms. This hypothesis is based on human and nonhuman neuroscientific evidence. [Copyright &y& Elsevier]
