Art Criticism

v. : ill. ; 22 cm (original analog pub.),If Art Criticism meets some of its editors’ hopes for it, we shall be able to claim the appearance of some art criticism, with subjects arising from the writers’ or editors’ decisions, rather than the art market’s. Articles on individual critics and on current groups and tendencies will lead towards the adequate history of art criticism so badly needed in relation to art and in relation to the literature of other disciplines.

Short Term Memory For Tempo In A Motor Timing Experiment, Sari Hooper

Open Access Master's Theses

This study investigated the role of short term memory in the motor reproduction of tempo. Seven undergraduate students participated in a finger-tapping experiment, in which retention intervals were incorporated into the classic continuation tapping paradigm. A two-way within-subjects design was employed, where subjects listen to and then attempt to reproduce a set tempo at 25 sub-second levels after retention intervals of 5 or 25 seconds. Musical Instrument Digital Interface (MIDI) software (Collyer, Boatright-Horowitz, & Hooper, 1997) was used to present stimulus tempos and record subjects tapping. Analyses of the inter-response intervals (IRls) indicated an effect of retention interval on the …

The Learning Spiral: Taking The Lead From How Young Children Learn, Martha Taylor Dever

Teacher Education and Leadership Faculty Publications

The questions at right, asked by 2nd-graders, launch a scientific inquiry about owls. As the 7-year-olds investigate stuffed owl specimens, they express their need to know. Some children continue to stroke the owls' feathers, touch a sharp claw, and ask questions about the mouth, while others immediately turn to printed materials to clarify their questions. This new experience with owls ignites the children's sense of wonder, and the intrinsically motivated scientific inquiry begins.

Shifting Paradigms In Island Biology, Sherwin Carlquist

Aliso: A Journal of Systematic and Floristic Botany

The ease of travel by jet aircraft has opened up island areas not only for study but also for introduction of weeds, pests, and pathogens. We are at a critical juncture in the study of island organisms, which have become more accessible at the same time that they are vanishing. With the urgency for study of island organisms, we have many new tools, especially molecular ones, which have validated the existence of long-distance dispersal in unexpected ways. These tools, together with the ease of staying for longer periods on islands, have permitted us to understand many aspects of evolutionary adaptation …

Conserving Plants As Evolutionary Entities: Successes And Unanswered Questions From New Zealand And Elsewhere, Ian A. E. Atkinson

Aliso: A Journal of Systematic and Floristic Botany

Saving a species from extinction may not insure that its future will continue as before, even when the surviving population is in a wild habitat. Former selection forces may be missing or replaced by others so that the species develops along a different evolutionary pathway. Such disruption of evolutionary direction may be particularly important for island taxa given that modification by humans and their introduced organisms is making many islands more similar to continental habitats. In restoring habitats for island species, special attention should therefore be given to identify ing the major selective forces likely to have been operating during …

Landscape Management Challenges On The California Channel Islands, William L. Halvorson

Aliso: A Journal of Systematic and Floristic Botany

Managing for sustained biodiversity and restoration of natural habitat has become increasingly important over the last two decades, first as mitigation for development (especially in wetlands), and , more recently in natural areas. The latter has come about as land managing agencies like the Department of Defense and Bureau of Land Management have seen the need to reverse the impact of past land uses and agencies like the National Park Service and The Nature Conservancy have taken on the responsibility for less-than-pristine lands.

On the California Channel Islands, the need for restoring and managing biodiversity is great, but this restoration …

A Floristic Study In The Diamond Creek Drainage Area, Gila National Forest, New Mexico, Eric H. Roalson, Kelly W. Allred

Aliso: A Journal of Systematic and Floristic Botany

The Diamond Creek drainage is one of the major watershed systems of the Gila National Forest in southwestern New Mexico. The purposes of this study were to catalog the vascular plants of a portion of this drainage area, describe the vegetation zones, locate any threatened, endangered, or sensitive plant species, and assess plant regeneration in areas that have been burned. The study area is located in the eastern portion of the Gila National Forest along the Black Range in the northwest corner of Sierra County. It covers approximately 5600 hectares (14000 acres) and ranges in elevation from 2250 to 3000 …

Ecophysiological Observations On Lane Mountain Milkvetch, Astragalus Jaegerianus (Fabaceae), A Proposed Endangered Species Of The Mojave Desert, Arthur C. Gibson, M. Rasoul Sharifi, Philip W. Rundel

Aliso: A Journal of Systematic and Floristic Botany

Astragalus jaegerianus, the Lane Mountain milkvetch, a perennial herbaceous legume, is a rare and very narrow endemic of the central Mojave Desert in San Bernardino County, California, and currently proposed to be listed as an endangered species. This herb grows in the protection of low shrubs. Anatomical observations revealed that leaflets are amphistomatic and have isolateral mesophyll, typical of full-sun desert leaves, and the green stem is an important photosynthetic organ, having abundant stomata and a cylinder of cortical chlore nchyma. Ecophysiological studies showed that this species requires high PFD (1400-1500 μmol m^-2s^-1) to achieve …

Phylogeny And Adaptation In The Encelia Alliance (Asteraceae: Helliantheae), Curtis Clark

Aliso: A Journal of Systematic and Floristic Botany

The three related genera Encelia, Enceliopsis, and Geraea comprise the alliance. The first consists primarily of shrubs and the latter two of herbaceous perennials and an annual. With the exception of two Encelia species of arid South America, all inhabit southwestern North America. Enceliopsis and Geraea are sister groups, and together form the sister group to Encelia, which includes two major clades. Especially in Encelia, there are diverse morphologies and a variety of ecological strategies marked by differences in habitat, vestiture, water balance, and photosynthetic parameters. The North American species of all three genera are obligate …

Cheilanthoid Ferns (Pteridaceae: Cheilanthoideae) In The Southwestern United States And Adjacent Mexico-A Molecular Phylogenetic Reassessment Of Generic Lines, Gerald J. Gastony, David R. Rollo

Aliso: A Journal of Systematic and Floristic Botany

Cheilanthoids are the most commonly encountered fern species of the arid southwest and other xeric habitats throughout the world. Cheilanthes, Notholaena, Pellaea, and Bommeria are the best known southwestern genera, but some authors recognize segregate genera such as Argyrochosma, Aspidotis, Astrolepis, and Pentagramma. Others reject distinctions among some of these genera as artificial, leaving cheilanthoid generic concepts in a state of flux. This unsettled taxonomy is often attributed to morphological homoplasy associated with adaptation to xeric habitats, suggesting the need for new analyses that do not depend on potentially misleading morphology. Nucleotide sequences …

Magnetostratigraphy Of Cueva Del Aleman, Isla De Mona, Puerto Rico And The Species Duration Of Audobon's Shearwater, Bruce C. Panuska, John M. Mylroie, Darrell Armentrout, Donald A. Mcfarlane

WM Keck Science Faculty Papers

Magnetostratigraphic analysis of deposits exposed in Cueva del Aleman shows two reversed and two normal chronozones. The lower normal polarity event is observed in a clastic dike and probably predates initial cave formation. Sediments deposited inside the cave proper show a R-N-R sequence and probably date to at least 1.8 Ma. A fossiliferous clastic dike contains normal polarity with an overlying reversed magnetozone. Audubon’s Shearwater (bird) bones occur in the dike, which is tentatively correlated with the lower N polarity zone predating cave formation. If this correlation is correct, the Audubon’s Shearwater (Puffinus lherminieri) range can be extended back to …

Sister Chromatid Exchange In Cultured Humanlymphocytes Treated With Carbosulfan, Ethlycarbamate And Ethly Methanesulfonat Separatelyand In Mixtures, Eyyüp Rencüzogullari, Mehmet Topaktas

Turkish Journal of Biology

The aim of this study was to investigate the ability of Carbosulfan (the effective ingredient in Marshal, a carbamate insecticide/nematocide), Ethyl Carbamate (EC=carcinogen and Ethyl Methanesulfonat (EMS=mutagen) separately and in mixtures to induce sister chromatid exchange (SCE) in human lymphocytes and to nivestigate whether the test substances, as a mixture had any syn-ergistic or antogonistic effect. Carbosulfan separately weakly induced SCE during the 48 hour treat-ment. Although EC separately could not induce SCE, EMS separately induced dose-dependently SCE at 24 and 48 hour treatments. EC increased the RI, while Carbosulfan and EMS decreased it during the 48 hour treatment. The …
