Deductive and Analogical Reasoning on a Semantically Embedded Knowledge Graph

Representing knowledge as high-dimensional vectors in a continuous semantic vector space can help overcome the brittleness and incompleteness of traditional knowledge bases. We present a method for performing deductive reasoning directly in such a vector space, combining analogy, association, and deduction in a straightforward way at each step in a chain of reasoning, drawing on knowledge from diverse sources and ontologies.Comment: AGI 201

Reproductive Differences among Delmarva Grass Shrimp (Palaemonetes pugio and P. vulgaris) Populations

Populations of female grass shrimps (Palaemonetes pugio and P. vulgaris) were sampled from five coastal embayments in Delaware, Maryland, and Virginia (Delmarva) and compared with respect to reproductive and life history attributes. We observed interspecific differences in timing of reproduction, carapace length, ratio of carapace length to total body length, body weight, clutch weight, clutch size, and egg volume. Onset of reproduction in P. vulgaris lagged behind P. pugio. Although there was no difference in the relationship between clutch size and carapace length for the two species, carapace length/total body length in P. pugio was greater than that in P. vulgaris. A multivariate analysis of variance indicated significant differences in carapace length, clutch weight, body weight, clutch size, and egg volume attributable to effects of species, population, and interactions between them. At all sites, P. pugio produced larger eggs than P. vulgaris. Although the two species did not differ in reproductive effort, both species exhibited increases in reproductive effort with latitude. Clutch size also tended to increase with latitude for both species. In populations where both species were abundant, adult females of P. pugio were longer and heavier and produced heavier egg masses comprised of fewer, larger eggs

From School to Adult Living: A Forum on Issues and Trends

This is the publisher's version, also found here: http://www.sped.org/EDITORS' NOTE: This article presents a forum for the personal views of four significant contributors to the conceptualization and implementation of transition programming as it exists in this country today. These individuals were selected from among a number of active contributors to the transition movement as representative spokespersons for the field. The questions posed by the guest editors were- developed from ideas and concerns that surfaced in the many manuscripts submitted for consideration in this special issue. Some of the issues raised in the questions reflect concerns expressed openly by professionals in the field, while others were inferred from more subtle or cautious statements. Each contributor received a set of questions to address. Each question was given to at least two contributors. They were encouraged to respond not only to their own set, but to any question of interest contained in other contributors' sets as well. As a result, a few questions were addressed by all four contributors. Their responses appear to reflect some consensus regarding the importance of the issues and trends suggested in the questions. Even so, the substance of their responses reflects a range of positions that would provoke keen consideration by readers
