Figure-ground assignment to a contour is a fundamental stage in visual processing. The current paper introduces a novel, highly general dynamic cue to figure-ground assignment: "Convex Motion." Across six experiments, subjects showed a strong preference to assign figure and ground to a dynamically deforming contour such that the moving contour segment was convex rather than concave. Experiments...

We will argue that this construction combines semantic and syntactic quirks that necessitate a constructional analysis. Further, we will show that specifying the pragmatic properties of the construction (and in particular the presuppositions that introduces) allows for a particularly elegant account of the construction’s distribution. This, in turn, provides further support for the sign-based v...

In this paper, I investigate the interaction of clause-modifying adjuncts, such as because clauses, with negation and the licensing of negative polarity items. I show how an account in which because clauses are adjuncts which can be basegenerated adjoined to either IP or VP explains the ambiguity of examples containing because clauses and negation, and how, in conjunction with the roofing theor...

E lizabeth Blackburn is the leading lady of telomere biology. Her discovery of telomerase with her graduate student Carol Greider in 1985 revealed for the fi rst time how the complex, repetitive ends of chromosomes—regions that normal DNA replication machinery can't cope with—are maintained (1).< I D > J C B 1 8 0 6 p i 1. e p s < / I D > Without telomerase, our chromosomes would shorten increm...

This paper is not very interesting. It briefly describes the motivation and implementation of banal,1 a format checker for PDF documents. Banal deduces the format specification of a document (e.g., font size, margins, etc.) and, optionally, compares the document formatting against a set of rules and reports any violations. Banal is most useful as part of a conference management system for confe...

Fig 1. Dr Robert Murray Ricketts, the early years. Ilay down principles and crystallize the information of their day. Such a scholar was Dr Robert Murray Ricketts (1920-2003) (Fig 1). His influence continues to contribute to our understanding of the biologic and mechanical enigmas that challenge us. His writings stimulate the student and promote advancements in his beloved specialty of orthodon...

We argue that the choice and composition of the Board of Directors is determined by the constituents of the ownership types within a firm. We categorize ownership in three distinct types-individual, corporate and institutional. We hypothesize and empirically link each ownership type to a type of Board Director. The board of directors is considered to be an important component of governance of a...
