The evolution of social media has introduced novel possibilities for work and interaction in organizations. The wiki technology is one important kind of social media technologies that is often used to facilitate the creation and sharing of organizational knowledge within communities. Using an affordance lens, we seek to understand the relationship between social media and organizations through ...

Ratioing describes when a reply earns more likes than an original post on social media. They also offer influencers opportunities to convert audience attention into political actions capable of temporarily shaping online discourse. Ratios are then one many influencer-driven strategies that leverage platform features and affordances direct audiences specific amplify the influencer’s content in c...

An autonomous robot should be able to evaluate the affordances that are offered by a given situation. Here we address this problem by designing a system that can densely predict affordances given only a single 2D RGB image. This is achieved with a convolutional neural network (ResNet), which we combine with refinement modules recently proposed for addressing semantic image segmentation. We defi...

The paper examines the notion that Information and Communication Technologies (ICT) have affordances that epitomize the features of our late modern age (Giddens, 1991) and explores whether these affordances (Salomon, 1993, p. 51) can be used to facilitate particular approaches to educational practice. It argues that a clear articulation of these affordances would enable us to understand how the...

The field of functional recognition or affordance estimation from images has seen a revival in recent years. As originally proposed by Gibson, the affordances of a scene were directly perceived from the ambient light: in other words, functional properties like sittable were estimated directly from incoming pixels. Recent work, however, has taken a mediated approach in which affordances are deri...

Clinical observations of kinesia paradoxica and freezing in patients with Parkinson's disease suggest that the automatic activation of motor programmes by visual stimuli may not require intact basal ganglia function, and that an increased sensitivity to such object affordances may contribute to some symptoms of the disease. Employing a paradigm that measures the degree of interference from obje...
