The broad field of “computers in education” includes a diversity of approaches to using computers for learning. Each approach is based on an epistemology: a theory of how knowledge is gained. In this presentation, I will characterize the uses of technology and their corresponding epistemologies. I will single out intersubjective epistemologies as timely for research and practice, and call for d...

Recent team boundary spanning literature has recommended a shift toward assessing the role of virtual tools – such as social media. Simultaneously the proliferation of Enterprise Social Media (ESM) points to the need to theorize and investigate the supra-individual usage of these tools, such as their usefulness for organizational groups. This paper responds to both mandates through a theoretica...

Contemporary semantic theories can be classified along two dimensions: (i) the way and time-course in which contextual factors influence sentence truth-conditions; and (ii) whether and to what extent comprehension involves sensory, motor and emotional processes. In order to explore this theoretical space, our ERP study investigates the time-course of the interaction between the lexically specif...

Figure 1: We present a view-based convolutional network that produces local, point-based shape descriptors. The network is trained such that geometrically and semantically similar points across different 3D shapes are embedded close to each other in descriptor space (left). Our produced descriptors are quite generic — they can be used in a variety of shape analysis applications, including dense...

Citation: Makris S (2015) Commentary: Viewing photos and reading nouns of natural graspable objects similarly modulate motor responses. Marino et al. (2014) in their paper (Frontiers in Human Neuroscience) have tried to investigate how the semantic processing of graspable objects involves an activation of the motor cortex in line with the affordance hypothesis originally proposed by Gibson (197...

In the second half of 20th century, ecological theory perception presented a new concept according to which it is not one-sided process within perceiver, in form representation and interpretation sensory data obtained from environment, but direct continuous interaction between percipient environment. Opposing almost intuitive acceptance numerous dualities based on traditionally accepted separat...

This paper reports an empirical study comparing the roles of representations in supporting face to face versus distance collaborative learning. Findings indicate that while face to face collaborators primarily use knowledge representations to summarize verbal reasoning, distributed collaborators also use knowledge representations to propose ideas before they are discussed, particularly ideas su...

Online review has become an important repository for consumers to make online buying decisions. However, writing online reviews is a voluntary behavior lacking guidelines and it is hard to guarantee the review quality generated. How to improve online review quality has become a challenge to online retailers and review aggregators. In this study, we explore the design of review writing interface...

General value functions (GVFs) in the reinforcement learning (RL) literature are long-term predictive summaries of outcomes agents following specific policies environment. Affordances as perceived action possibilities with valence may be cast into predicted policy-relative goodness and modeled GVFs. A systematic explication this connection shows that GVFs especially their deep-learning embodime...

Abstract Drawing from the social capital framework and socioemotional selectivity theory, this study examines how individuals’ future time perspective (FTP) alters their processes, which further influences well-being. A two-wave survey was conducted across WeChat users possessing different FTPs. The findings showed that bonding bridging accumulation were attributed to differential affordances, ...
