Why are humans so vulnerable to pain in interpersonal relations and can so easily hurt others physically and emotionally? We theoretically examine whether being offensively strong but defensively weak can evolve as a strategic trait that fosters cooperation. We study a population comprised of “thick-skinned” and “thinskinned” agents by using an indirect evolution model that combines rational ch...

How science and policy interact has been a major research focus in the International Relations (IR) tradition, using the epistemic community (EC) concept, as well as in the alternative perspective of Science and Technology Studies (STS). Should science be autonomous and as apolitical as possible in order to ‘speak truth to power’, as suggested by EC or should the inevitable entanglement of scie...

We present an unsupervised connectionist model for grounding color, shape and spatial relations of two objects in 2D space. The model constitutes a two-layer architecture that integrates information from visual and auditory inputs. The images are presented as the visual inputs to an artificial retina and fiveword sentences describing them (e.g. “Red box above green circle”) serve as auditory in...

Near equilibrium, Green-Kubo relations provide microscopic expressions for macroscopic transport coefficients in terms of equilibrium correlation functions. At their core, they are based on the intimate relationship between response and fluctuations as embodied by fluctuation-dissipation theorem, a connection generically broken far from equilibrium. In this work, we identify class perturbations...

Interpersonal relations are in constant flux; close friendships often dissolve into enmity. We examine linguistic cues augur transitions from friendly bonds into hostile relations through conversations from online strategy games. We look at betrayal from two perspectives in a classification framework: we characterize the difference between friendships that break and friendships that last, and w...

Interpersonal communication represents one of the most important aspects in the process of education. Its role may be seen at multiple levels. It can also be considered as a generator of interpersonal relations in the educational process as well as a consequence of the established interpersonal relations at the subject level in the educational process. In other words, interpersonal communicatio...

We consider stability concepts for random matchings where agents have preferences over objects and objects have priorities for the agents. When matchings are deterministic, the standard stability concept also captures the fairness property of no (justified) envy. When matchings can be random, there are a number of natural stability / fairness concepts that coincide with stability / no envy when...

Tarski showed that mathematics can be built up in the equational theory EqRA of relation algebras (RA's), hence EqRA is undecidable. He raised the problem "how much associativity of relation composition is needed for this result." Maddux defined the classes NA 3 WA "J SA D RA by gradually weakening the associativity of relation composition, and he proved that the equational theory of SA is stil...
