Prosocial decisions may lead to unequal payoffs among group members. Although an aversion to inequity has been found in empirical studies of both human and nonhuman primates, the contexts previously studied typically do not involve a trade-off between pro-sociality and inequity. Here we investigate the apparent coexistence of these two factors, specifically the competing demands of prosociality...

This paper addresses a current issue in environmental valuation, namely, the extent to which environmental preferences depart from the usual economic paradigm to incorporate some lexicographic elements. After a theoretical discussion the paper reviews attempts to explore this question empirically by supplementing contingent valuation analyses with an exploration of the motives behind willingnes...

This work incorporates Selectional Preferences (SP) into a Semantic Role (SR) Classification system. We learn separate selectional preferences for noun phrases and prepositional phrases and we integrate them in a state-of-the-art SR classification system both in the form of features and individual class predictors. We show that the inclusion of the refined SPs yields statistically significant i...

Each month many women experience an ovulatory cycle that regulates fertility. Whereas research finds that this cycle influences women’s mating preferences, we propose that it might also change women’s political and religious views. Building on theory suggesting that political and religious orientation are linked to reproductive goals, we tested how fertility influenced women’s politics, religio...

Many preference aggregation problems are not, by nature, one-shot. In these settings, voter preferences need to be repeatedly aggregated as a function of the underlying pool of options that are being voted over. For example, imagine that a firm votes an offer to a candidate. If the offer is declined, then the pool of options shrinks, votes are aggregated once more, and a subsequent offer is mad...

Consider two graphs G and H. Let H[G] be the lexicographic product of H and G, where H is the lexicographic product of the graph H by itself k times. In this paper, we determine the spectrum of H[G] and H whenG andH are regular and the Laplacian spectrum ofH[G] andH for G and H arbitrary. Particular emphasis is given to the least eigenvalue of the adjacency matrix in the case of lexicographic p...

Regardless of their name (dictionary, glossary, encyclopaedia, or even ‘leximat’, in the case of a new generation of online, semi-automated lexicographic tools), subject-field, purpose, or medium (paper or cyber), lexicographic reference works should be regarded as functional information tools that are solely designed to cater to the information needs of their users in different usage situation...
