An exhibition of paintings of the American Old West caught my attention one afternoon, after I had wandered across the street from our affiliate V.A. outpatient clinic to the Pennsylvania Academy of the Fine Arts. A popular theme among these romanticized views of the American frontier was the image of the trapper; alone, silent figure working at the nation\u27s interface with the unknown. Several paintings depicted a custom known as the rendez-vous, a semi-annual occurrence wherein the trappers gathered eastward to river outposts in order to socialize, trade information and hand-made maps, restock supplies, and display for sale the bounty gleaned from the previous season

As the Jefferson Journal of Psychiatry continues in its early growth phase, having accomplished a successful synthesis to become a national publication, we note its own apparent power of accommodation equal to the strain of fusing and adjusting internal and external changes. Psychiatric residency in itself demands such accommodation. A group of finishing second year residents were taking stock of the fir st half of this process: They noted the difficulty in reconciling their initial conceptions and intentions with the subsequent realization of the limits to knowledge or intervention; they called this disillusionment. Others spoke of a converse strengthening as better insight into the range of their abilities made them observe more clearly, act with more leverage. This is also disillusionment in the more positive sense

Tachinid (Diptera) parasitoids of Hyphantria cunea (Lepidoptera: Arctiidae) in its native North America and in Europe and Asia – a literature review

The polyphagous pest fall webworm, Hyphantria cunea (Drury), from North America has invaded at least 20 European, 2 Eurasian (Russia and Turkey) and 10 Asian countries since 1940. At least 54 species of tachinids (Diptera: Tachinidae) from 3 subfamilies, 10 tribes and 30 genera parasitise it. Forty six (85%) of the species are from the subfamily Exoristinae, and 17, 12 and 10 species are from 3 of its tribes, Goniini, Eryciini and Exoristini, respectively. Twenty eight of the 54 species are from 7 of the 30 genera: Exorista Meigen (7), Panzeria Robineau-Desvoidy (4), Blondelia Robineau-Desvoidy (4), Carcelia Robineau-Desvoidy (4), Hyphantrophaga Townsend (3), Lespesia Robineau-Desvoidy (3) and Zenillia Robineau-Desvoidy (3). The majority of the 30 genera either deposit microtype eggs that are consumed by the host or oviposit on the host

Advanced Programming Language Features for Executable Design Patterns "Better Patterns Through Reflection

The Design Patterns book [GOF95] presents 24 time-tested patterns that consistently appear in well-designed software systems. Each pattern is presented with a description of the design problem the pattern addresses, as well as sample implementation code and design considerations. This paper explores how the patterns from the "Gang of Four'', or "GOF'' book, as it is often called, appear when similar problems are addressed using a dynamic, higher-order, object-oriented programming language. Some of the patterns disappear -- that is, they are supported directly by language features, some patterns are simpler or have a different focus, and some are essentially unchanged

Efficient diagnosis of multiprocessor systems under probabilistic models

The problem of fault diagnosis in multiprocessor systems is considered under a probabilistic fault model. The focus is on minimizing the number of tests that must be conducted in order to correctly diagnose the state of every processor in the system with high probability. A diagnosis algorithm that can correctly diagnose the state of every processor with probability approaching one in a class of systems performing slightly greater than a linear number of tests is presented. A nearly matching lower bound on the number of tests required to achieve correct diagnosis in arbitrary systems is also proven. Lower and upper bounds on the number of tests required for regular systems are also presented. A class of regular systems which includes hypercubes is shown to be correctly diagnosable with high probability. In all cases, the number of tests required under this probabilistic model is shown to be significantly less than under a bounded-size fault set model. Because the number of tests that must be conducted is a measure of the diagnosis overhead, these results represent a dramatic improvement in the performance of system-level diagnosis techniques

On the existence of infinitely many closed geodesics on orbifolds of revolution

Using the theory of geodesics on surfaces of revolution, we introduce the period function. We use this as our main tool in showing that any two-dimensional orbifold of revolution homeomorphic to S^2 must contain an infinite number of geometrically distinct closed geodesics. Since any such orbifold of revolution can be regarded as a topological two-sphere with metric singularities, we will have extended Bangert's theorem on the existence of infinitely many closed geodesics on any smooth Riemannian two-sphere. In addition, we give an example of a two-sphere cone-manifold of revolution which possesses a single closed geodesic, thus showing that Bangert's result does not hold in the wider class of closed surfaces with cone manifold structures.Comment: 21 pages, 4 figures; for a PDF version see http://www.calpoly.edu/~jborzell/Publications/publications.htm

A Study of the Sensitivity of Plethodon cinereus (Caudata: Plethodontidae) to Damage-Released Cues from Conspecifics

Some prey species vary the intensity of antipredator responses according to the perceived level of threat associated with different concentrations of chemical cues related to predation. Here, we examine whether Red-Backed Salamanders (Plethodon cinereus) respond to different concentrations of damage-released cues from the tails of conspecifics in a threat-sensitive manner. We exposed salamanders either to a control or to damage-released cues from conspecifîcs at one of three different concentrations. We found that salamanders exposed to damage released cues significantly decreased their activity compared to salamanders exposed to a control. However, the intensity of the responses was not related to the concentration of the cue, suggesting that individuals of P. cinereus do not respond in a threat-sensitive fashion at the concentrations tested
