26 Hibler, Michael J.Notes on thread models in Mach 3.0During the Mach In-Kernel Servers work, we explored two alternate thread models that could be used to support traps to in-kernel servers. In the "migrating threads" model we used, the client's thread temporarily moves into the server's task for the duration of the call. In t h e "thread switching" ...Thread models; In-kernel servers; Thread switching; Mach 3.01993
27 Coley, Phyllis D.; Kursar, Thomas A.Colonization of tropical rain forest leaves by epiphylls: effects of site and host plant leaf lifetimeIn humid tropical regions, leaves are frequently colonized by epiphylls (Richards 1954, Pocs 1978, 1982). Lichens and liverworts usually dominate, although mosses, algae, and cyanobacteria can also occur (Winkler 1971, Smith 1982). The interactions between epiphylls and host leaves have not been wel...Tropical forest; Epiphylls; Panama; Hybanthus prunifolius; Light interception1993
28 Miller, Jan D.Surface phase transitions of adsorbed collector molecules as revealed by in-situ FT-IR/IRS spectroscopyIt has been shown by inspection of FT-IR/IRS spectra that the alkyl conformation of adsorbed collectors can be determined. The conformations of adsorbed collectors were interpreted in terms of bulk solution phases of the collectors. Such analysis was performed on the CaF2/oleate, A1203/SDS and KC1/...Oleates; Micellar; In situ analysis; Adsorption1993
29 Sobh, Tarek M.; Henderson, Thomas C.Intermediate results in active inspection and reverse engineeringIn previous work [18], we have proposed a new design for inspection and reverse engineering environments.

31 Lindstrom, Gary E.Modules as values in a persistent object storeWe report on an object manager (OM) providing persistent implementations for C ++ classes. Our OM generalizes this problem to that of managing persistent modules, where the module concept is an abstract data type (ADT).

32 Newton, MariaRelationship of task and ego orientation to performance: cognitive content, affect, and attributions in bowlingThe purpose of the present study was to examine the relationship of individual differences in goal orientation to mid-activity cognitive content and affect and post-performance attributions across three games of bowling. Forty-seven undergraduate students enrolled in bowling activity classes were r...Goal-directed behavior; Task and Ego Orientation in Sport Questionnaire; Sport psychology1993
33 Davidson, Diane W.Ant-plant symbioses in Africa and the neotropics : history, biogeography and diversitySymbiotic ant-plant relationships afford an excellent opportunity to analyze the effects of both historical and ecological factors on the evolution of mutualisms. Occurring in tropical forests throughout the world, all myrmecophytic plants provide food and permanent housing to ants; the ants, in t...Ant-plant symbiosis; Africa; Neotropics; Myrmecophytes; Plant-ants1993

35 Fogel, Alan DaleDeveloping through relationships origins of communication, self, and cultureI began to consider the study of relationships as an intellectual vocation in 1970, the result of two years of college teaching that was part of my work as a United States Peace Corps volunteer in Bogota, Colombia. After another year I began my doctoral training in the Department of Education at th...1993
36 Lindstrom, Gary E.Modular language processors as framework completionsThe conceptual and specificational power of denotational semantics for programming language design has been amply demonstrated. We report here on a language implementation method that is similarly semantically motivated, but is based upon object-oriented design principles, and results in flexible an...Modular language processors; Denotational semantics; Framework completions1993
37 Clayton, Dale H.Common grackle anting with lime fruit and its effect on ectoparasitesAnting is stereotyped behavior in which birds ex- pose themselves to fluid-secreting ants or other pun- gent substances. During "active" anting a bird crush- es an ant in the bill and rubs it frenetically through its plumage (Rothschild and Clay 1952). During "passive" anting a bird entices ants to ...Quiscalus quiscala; Columbicola columbae; Anting; Ectoparasites1993
38 Morse, Michael DavidSpectroscopic studies of jet-cooled AINiResonant two-photon ionization spectroscopy has been used to interrogate diatomic AlNi produced by laser vaporization of a 1:l alloy target in a supersonic molecular beam of helium. Although a large density of states in this molecule prohibits a concise elucidation of its electronic structure, the p...1993
39 Olivera, Baldomero M.; ; McIntosh, J. MichaelLocalization of [125I] ω-conotoxin GVIA binding in human hippocampus and cerebellumTHE peptide toxin ω-conotoxin GVIA (ω-CgTx) has been shown to be a high affinity ligand for N-type calcium channels in the brain. We have employed [125I]ω-CgTx to localize N-type channels in human hippocampus and cerebellum using autoradiography. Ten micron thick slidemounted tissue sections of...Conotoxins; Peptide toxins1993
40 Couldwell, William T.Penetrating craniocerebral injury resultant from gunshot wounds: gang-related injury in children and adolescentsWE PROSPECTIVELY AND retrospectively reviewed a series of 780 patients who presented to the University of Southern California/Los Angeles County Medical Center with a diagnosis of gunshot wound to the brain during an 8-year period.
