underreact in the short run. The underreaction means that the momentum traders can profit by trendchasing. However, if they can only implement simple (i.e., univariate) strategies, their attempts at arbitrage must inevitably lead to overreaction at long horizons. In addition to providing a unified account

Philosophers writing about the rationality of an agent's intentions often understand rationality in one of two ways. According to one way, rational intentions are those intentions an agent has along with beliefs whose truth would provide sufficient reason for having those intentions. This understanding of rationality is often associated with the work of Derek Parfit, from whom I'll borrow an example to illustrate the idea: if one falsely believes the hotel is on fire and intends to jump into the canal, the intention to jump into the canal is rational, since were the belief true – that is, were the hotel on fire – one would have sufficient reason to intend to jump into the canal. 1 On this understanding of rationality, when one has no false beliefs, the intentions it is rational for one to have are just those one has sufficient reason to have. For instance, when one knows that the hotel is on fire, it is rational, and one has sufficient reason, to intend to jump into the canal. According to a second way of understanding the rationality of intentions, rational intentions are those intentions that do not violate any of the requirements of practical

Snakes provide a unified account of a number of visual problems, in-cluding detection of edges, lines, and subjective contours; motion tracking; and stereo matching. We have used snakes successfully for interactive interpretation, in which user-imposed constraint

. Cases where scalar items and presupposition triggers co-occur are also accounted for. The main focus is the unification between various phenomena: scalar implicatures, free choice effects and presupposition projection. Yet, the system can be split

In an attempt to establish both phenomena with the same stimuli—and account for them with the same model—we asked observers to identify (as clockwise or anticlockwise of vertical) slightly tilted targets surrounded by tilted distractors.

A hallmark of the English verb lexicon is the availability of multiple argument realization options for many English verbs. Studies of the English verb lexicon have drawn attention to one facet of this phenomenon: the availability of a range of object alternations (Levin 1993)—alternate realizations of the VP-internal arguments of apparently triadic verbs. One of the best-known of these alternations is the locative alternation, which comes in “putting ” and “removing ” subtypes, as illustrated in (1) and (2). (1) Locative Alternation — “putting ” subtype: a. Jill sprayed paint on the wall. b. Jill sprayed the wall with paint. (2) Locative Alternation — “removing ” subtype: a. Jack wiped crumbs off the counter. b. Jack wiped the counter. There are many studies of object alternations, particularly the locative and dative alternations, yet few of them consider the full spectrum of object alternations,

Abstract. In this paper I shall propose an analysis of the Hausa bound genitive marker which unifies its use in possessives and partitives with that in gerundive and pre-nominal adjectival constructions (see Newman, 2000 and Jaggar (2001) for a detailed overview). I shall provide evidence
