Operations Research And Organizational Decision-Making In Academic Libraries, Therrin C. Dahlin Jan 1991

Operations Research And Organizational Decision-Making In Academic Libraries, Therrin C. Dahlin

Faculty Publications

Operations research entered the library scene in the 1960s and '70s, and has attracted much interest from librarians. This paper examines the assumptions made by selected operations researchers concerning organizational decision-making in academic libraries. The assumptions then are compared to Richard L. Daft's contingency framework of organizational decision-making to determine the appropriateness of applying operations research assumptions and methods to organizational decision-making in an academic library setting. A review of the operations researchers' assumptions and Daft's framework suggests that the operations research approach may be appropriately applied to only a relatively narrow category of problems in academic libraries that match …


Teacher Education: Student Teacher Views Vs. Those Of Cooperating Teachers, Richard Stahlhut, Lynn Williford, Richard Hawkes, Joseph Fratianni Jan 1991

Teacher Education: Student Teacher Views Vs. Those Of Cooperating Teachers, Richard Stahlhut, Lynn Williford, Richard Hawkes, Joseph Fratianni

Faculty Publications

A survey was conducted on the quality of preparation in teacher education of student teachers at the University of Northern Iowa and their performance level during student teaching. Student teachers were asked to assess teacher education program contributions to 29 competencies relevant to teaching effectiveness; plus their overall teacher effectiveness. Similarly; cooperating teachers were asked to assess the same competencies as exhibited by the student teachers they supervised. Of the 369 (78.5 percent) questionnaires returned; 192 were from student teachers and 177 were from cooperating teachers. Data analysis was based on matched pairs of responses. An overall summary of the …


Effects Of Visual/Verbal Associations, Anna C. Martin Jan 1991

Effects Of Visual/Verbal Associations, Anna C. Martin

Faculty Publications

Different effects of instructional strategies on recall and comprehension of terms frequently used in formal analysis of art were examined. The study looked at a synthesis of three theoretical positions: dual-coding theory; schema theory; and elaboration theory. Two-hundred and fifty sixth-grade students were randomly assigned to three groups: control subjects; graphic subjects; and transformational subjects. Instruments consisted of Raven's Standard Progressive Matrices (RSPM) and the Art Vocabulary Test (AVT). The program consisted of three phases: (1) a 10-minute study session; (2) an interactive discussion; and (3) a drawing task. The results suggested that imagery strategies help students form and retain …

Analysis Of Bacterial Genome Organization And Replication Using Pulsed-Field Gel Electrophoresis, A. Dingwall, L. Shapiro, Bert Ely Oct 1990

Analysis Of Bacterial Genome Organization And Replication Using Pulsed-Field Gel Electrophoresis, A. Dingwall, L. Shapiro, Bert Ely

Faculty Publications

The techniques described in this chapter provide a framework with which to begin an analysis of important features of bacterial genome organization and gene function. In this report we describe the preparation of chromosomal DNA, conditions for digestion with restriction endonucleases, and electrophoretic methods that result in the optimal resolution of large DNA restriction fragments. The sizes of the separated fragments can be summed to accurately determine genome size. The fragments can also be probed in hybridization experiments to produce low-resolution genomic restriction maps, and the precise locations of insertion or deletion mutations can be rapidly identified. In addition, PFGE …

The Extended Tracking Network And Indications Of Baseline Precision And Accuracy In The North Andes, Jeffrey T. Freymueller, James N. Kellogg Mar 1990

The Extended Tracking Network And Indications Of Baseline Precision And Accuracy In The North Andes, Jeffrey T. Freymueller, James N. Kellogg

Faculty Publications

The CASA UNO Global Positioning System (GPS) experiment (January-February 1988) included an extended tracking network which covered three continents in addition to the network of scientific interest in Central and South America. The repeatability of long baselines (400-1000 km) in South America is improved by up to a factor of two in the horizontal vector baseline components by using tracking stations in the Pacific and Europe to supplement stations in North America. In every case but one, the differences between the mean solutions obtained using different tracking networks was equal to or smaller than day-to-day rms repeatabilities for the same …

Faculty Publications

The CASA UNO GPS (Global Positioning System) experiment (January-February 1988) has provided the first epoch baseline measurements for the study of plate motions and crustal deformation in and around the North Andes. Two dimensional horizontal baseline repeatabilities are as good as 5 parts in 108 for short baselines (100-1000km), and better than3 parts in 108 for long baselines (>1000km). Vertical repeatabilities are typically 4 -6 cm, with a weak dependence on baseline length. The expected rate of plate convergence across the Colombia Trench is 6-8 cm/yr, which should be detectable by the repeat experiment planned for 1991. …

Red-Cockaded Woodpeckers Vs Rat Snakes: The Effectiveness Of The Resin Barrier, D. Craig Rudolph, Howard Kyle, Richard N. Conner Jan 1990

Red-Cockaded Woodpeckers Vs Rat Snakes: The Effectiveness Of The Resin Barrier, D. Craig Rudolph, Howard Kyle, Richard N. Conner

Faculty Publications

Red-cockaded Woodpeckers (Picoides borealis) excavate resin wells in the immediate vicinity of roost and nest cavity entrances. Resin wells are worked regularly, resulting in a copious and persistent resin flow that coats the tree trunk, especially below cavity entrances. Red-cockaded Woodpeckers also scale loose bark from cavity trees and closely adjacent trees. These two behaviors result in smooth, sticky surfaces surrounding cavity entrances. Climbing experiments on cavity, scaled, and control trees using rat snakes (Elaphe obsoleta) demonstrate that these behaviors produce a resinous barrier that is highly effective in preventing predatory snakes from gaining access to active Red-cockaded Woodpecker cavities.


Experimental Reintroduction Of Red-Cockaded Woodpeckers, D. Craig Rudolph, Howard Kyle, Richard N. Conner Jan 1990

Experimental Reintroduction Of Red-Cockaded Woodpeckers, D. Craig Rudolph, Howard Kyle, Richard N. Conner

Faculty Publications

The Red-cockaded Woodpecker (Picoides borealis) is an endangered species endemic to the pine forests of the southeastern United States (Jackson 1971). Deforestation and habitat alteration have severely affected Red-cockaded Woodpecker populations; current populations are isolated and most are declining (Jackson 1971, Lennartz et al. 1983, Conner and Rudolph 1989, Costa and Escano 1989). The species has been extirpated from significant areas of suitable or potentially suitable habitat.


Emergency In The Constitutional Law Of The United States, William B. Fisch Jan 1990

Emergency In The Constitutional Law Of The United States, William B. Fisch

Faculty Publications

In the following report I shall concentrate on the law as pronounced by the United States Supreme Court, which has, within the sphere of judicial competence, the last say on the interpretation of the Constitution. The volume of significant litigation on the subject which stops below the Supreme Court has been relatively light, and the constitutional law declared by the lower courts has played a less significant role than is the case in many other issues. Indeed, as we shall see, the Supreme Court itself has had less to say on the topic than might be hoped for. I shall …

A New Chloroplast Protein Is Induced By Growth On Low Co2 In Chlamydomonas Reinhardtii, Catherine B. Mason, Livingston J. Manuel, James V. Moroney Jan 1990

A New Chloroplast Protein Is Induced By Growth On Low Co2 In Chlamydomonas Reinhardtii, Catherine B. Mason, Livingston J. Manuel, James V. Moroney

Faculty Publications

The biosynthesis of a 36 kilodalton polypeptide of Chlamydomonas reinhardtii was induced by photoautotrophic growth on low CO2. Fractionation studies using the cell-wall-deficient strain of C. reinhardtii, CC-400, showed that this polypeptide was different from the low CO2-induced periplasmic carbonic anhydrase. In addition, the 36 kilodalton polypeptide was found to be localized in intact chloroplasts isolated from low CO2-adapting cultures. This protein may, in part, account for the different inorganic carbon uptake characteristics observed in chloroplasts isolated from high and low CO2-grown C. reinhardtii cells.


Distribution And Rate Of Methane Oxidation In Sediments Of The Florida Everglades, G. M. King, P. Roslev, H. Skovgaard Jan 1990

Distribution And Rate Of Methane Oxidation In Sediments Of The Florida Everglades, G. M. King, P. Roslev, H. Skovgaard

Faculty Publications

Rates of methane emission from intact cores were measured during anoxic dark and oxic light and dark incubations. Rates of methane oxidation were calculated on the basis of oxic incubations by using the anoxic emissions as an estimate of the maximum potential flux. This technique indicated that methane oxidation consumed up to 91% of the maximum potential flux in peat sediments but that oxidation was negligible in marl sediments. Oxygen microprofiles determined for intact cores were comparable to profiles measured in situ. Thus, the laboratory incubations appeared to provide a reasonable approximation of in situ activities. This was further supported …


The Burden Of Responsibility In The Libro De Buen Amor, Lynn Williams Jan 1990

The Burden Of Responsibility In The Libro De Buen Amor, Lynn Williams

Faculty Publications

In three of the early sections of the Libro de buen amor, Juan Ruiz explains to his public how, for various reasons, he is conditioned to love women. In stanzas 71-76 he uses the unimpeachable authority of Aristotle to argue that men and animals are biologically determined to seek 'juntamiento con fenbra plazentera' (st. 71d), and since he is a man like any other, it is natural, perhaps even inevitable, that from time to time he too should feel the attraction of the opposite sex. Paraphrasing St Paul (I Thessalonians 5.21), the Archpriest tells us rather cheekily that one must …


Tetracycloalkenyl-Meso-Tetraphenylporphyrins As Models For The Effect Of Non-Planarity On The Light Absorption Properties Of Photosynthetic Chromophores, Craig J. Medforth, M. Dolores Berber, Kevin M. Smith, John A. Shelnutt Jan 1990

Tetracycloalkenyl-Meso-Tetraphenylporphyrins As Models For The Effect Of Non-Planarity On The Light Absorption Properties Of Photosynthetic Chromophores, Craig J. Medforth, M. Dolores Berber, Kevin M. Smith, John A. Shelnutt

Faculty Publications

As the size of the cycloalkenyl ring in synthetic C5-C7 tetracycloalkenyl-meso-tetraphenylporphyrins (TCnTPP) is increased the porphyrin core changes from planar to non-planar, showing that porphyrins with well-defined degrees of ruffling can be synthesized for use in systematic studies to determine the effects of non-planarity. © 1990.


Dynamics And Controls Of Methane Oxidation In A Danish Wetland Sediment, Gary M. King Jan 1990

Dynamics And Controls Of Methane Oxidation In A Danish Wetland Sediment, Gary M. King

Faculty Publications

Abstract The patterns and controls of methane oxidation in a Danish wetland sediment have been determined using a combination of slurry and intact core techniques. Results from slurries indicated that methane oxidation was effectively inhibited by low concentrations of nitrapyrin (9 μM) and acetylene (0.5 μM) but that oxidation was relatively insensitive to pH between 6 and 8; in addition, high concentrations of ammonia (1 mM) decreased oxidation, especially at alkaline pH. Kinetic analyses of methane oxidation in slurries indicated that Vmax was high relative to values reported for other sediments, that Vmax changed seasonally, that Km was consistently low …


Lévy Laplacian Of Generalized Functions On A Nuclear Space, Hui Hsiung Kuo, Nobuaki Obata, Kimiaki Saitô Jan 1990

Lévy Laplacian Of Generalized Functions On A Nuclear Space, Hui Hsiung Kuo, Nobuaki Obata, Kimiaki Saitô

Faculty Publications

The Lévy Laplacian ΔF(ξ) = limN→∞N-1∑n = 1N 〈F″(ξ),en⊗ en〉 is shown to be equal to (i) ∝TF″s″(ξ;t)dt, where Fs″ is the singular part of F″, and (ii) 2limρ{variant}→0ρ{variant}-2(MF(ξ,ρ{variant})-F(ξ)), where MF is the spherical mean of F. It is proved that regular polynomials are Δ-harmonic and possess the mean value property. A relation between the Lévy Laplacian Δ and the Gross Laplacian ΔGF(ξ) = ∑n = 1∞=〈F″(ξ),en⊗ en〉 is obtained. An application to white noise calculus is discussed. © 1990.
