Professor D'Arcy W. Thompson has recently revived a conjecture of Lauth on Geoponica, XIII, 8, 1, which runs as follows: εις οκ σονται ν χωρ ν νθιονἢ ρτεμσιον ἢ βρτονον περ τν πα$$υλιν υτεσς. τος δ ντας λσεις ν . The conjecture is that ντας is the Egyptian hontasu, ‘lizard.’ That this would make sense is obvious; but the usage of the Geop. itself, to say nothing of other authors, indicates that the word is simply what it appears to (...) be, namely the pres. part, of εμ. Thus we find in X, 46 τ ςκα σκληκας ¿ π¿ισειν μλλων φυτεειν μπξς σκλλ τν κλδ¿ν, τ¿ς δ ντας ναιρες ν κ.τ.λ. Here the explanation ‘lizards’ would hardly be reasonable; still more cogent, however, is XII, 8, 2–3, ¿κ σονται … τς δ οσας κμπας διαθερς, where no such conjecture is possible. Not dissimilar is XII, 19, 9, τς τε γρ οσας ψλλας θερεικα λλας οκ γενσθαι. All these extracts are taken from authors of the second and third centuries A.D., though we have no means of knowing how closely their actual wording is followed; it is therefore in point to cite a passage of Galen, the opening paragraph of the tractate περ αρσεων Medicine, he says, has for its aim health, and a physician must know how to bring about health if absent and preserve it if present . καλεται δ, he continues, τ μν ργαζμενα τν μ οσαν γειατν τε καβοηθματα, τ δ φυλττοντα τν οσαν γιειν διαιτματα. In other words, ὢν can be used in much the same sense as παρν. This is no novelty of Roman times, for we may compare, for instance, Soph. Ant. 1109, ο ' ντες ο τ'πντες, and El, 305 τς οσας … κα τς ποσας λπδας. (shrink)

This is a field-based disguised case which describes a dilemma faced by the protagonists; do they continue to do business with a land developer who has assisted them in the past when now the developer chooses to, against their recommendations, also do business with their ex-business partner? The problem for the characters in question is whether or not to work on a project that will yield them a net profit of $4 million dollars given the fact it would require them (...) to work in the same development as their former business associate. The central characters are afraid that their ex-partner will be a destabilizing factor in the development of the project and that their work sites will be in jeopardy of being vandalized. Several factors complicate this situation including: the developer’s desire for a quick land purchase, the developer’s changing the discount rate from 20% to 10% perhaps based upon difficulties that surrounded the first land deal, the protagonists’ plans to build their own homes in this new development, and the negative relationship between the protagonists and the ex-business partner. The case has a difficulty level appropriate for a sophomore or junior level course. The case is designed to be taught in one class period and is expected to require between three to five hours of outside preparation by students. (shrink)

According to the theory of lexical access presented by Levelt, Roelofs & Meyer, processing of semantic–syntactic information and phonological information proceeds in a strictly discrete, serial manner. We will evaluate this claim in light of recent evidence from the literature and unpublished findings from our laboratory.

The locomotor pattern of a goldfish may be described by 17 locomotor variables whose time series are known to exhibit distinct patterns of autocorrelation. The present model reduces the set of 17 variables to a set of seven predictor variables which optimize the prediction of future locomotor behavior. These seven variables are then grouped into two clusters by a dendogram analysis, and it is shown that the clusters are also characterized by their strength of prediction. A locomotor control model is (...) then formulated where one cluster is interpreted to be a level of activity factor and the other is hypothesized to be a turning behavior factor. (shrink)

The traditional Dung networks depict arguments as atomic and study the relationships of attack between them. This can be generalised in two ways. One is to consider various forms of attack, support, feedback, etc. Another is to add content to nodes and put there not just atomic arguments but more structure, e.g. proofs in some logic or simply just formulas from a richer language. This paper offers to use temporal and modal language formulas to represent arguments in the nodes of (...) a network. The suitable semantics for such networks is Kripke semantics. We also introduce a new key concept of usability of an argument. This is the beginning of a continuing research for adding contents to the nodes of an argumentation network. This research will allow us to address notions like ?what does it exactly mean for a node to attack another? or ?what does it mean for a network to be consistent? or ?can we give proper proof rules to manipulate networks?, and more.

In orthodox quantum mechanics, it has virtually become the custom to identify properties of a physical system with operationally testable propositions about the system. The causes and consequences of this practice are explored mathematically in this paper. Among other things, it is found that such an identification imposes severe constraints on the admissible states of the physical system.

The focus of this study was to analyze the content, distribution, and comparative genome relationships of 996 chromosome bin-mapped expressed sequence tags accounting for 2266 restriction fragments on the homoeologous group 3 chromosomes of hexaploid wheat. Of these loci, 634, 884, and 748 were mapped on chromosomes 3A, 3B, and 3D, respectively. The individual chromosome bin maps revealed bins with a high density of mapped ESTs in the distal region and bins of low density in the proximal region of the (...) chromosome arms, with the exception of 3DS and 3DL. These distributions were more localized on the higher-resolution group 3 consensus map with intermediate regions of high-mapped-EST density on both chromosome arms. Gene ontology classification of mapped ESTs was not significantly different for homoeologous group 3 chromosomes compared to the other groups. A combined analysis of the individual bin maps using 537 of the mapped ESTs revealed rearrangements between the group 3 chromosomes. Approximately 232 of the consensus mapped ESTs matched sequences on rice chromosome 1 and revealed large- and small-scale differences in gene order. Of the group 3 mapped EST unigenes ∼21 and 32% matched the Arabidopsis coding regions and proteins, respectively, but no chromosome-level gene order conservation was detected. (shrink)
