The Effects Of An Individualized Instruction Workshop And Its Related Follow-Up Program On The Attitudes And Behavior Of Selected Elementary Teachers And Their Students: Final Report, Helen Dell, Warren Kallenbach Nov 1972

The Effects Of An Individualized Instruction Workshop And Its Related Follow-Up Program On The Attitudes And Behavior Of Selected Elementary Teachers And Their Students: Final Report, Helen Dell, Warren Kallenbach

Faculty Publications

The effects of an individualized instruction workshop and its related follow-up program on the attitudes and behavior of selected elementary teachers and their students were discussed in this report. Participants were teachers in a four-day workshop on individualizing instruction. The workshop included training in classroom procedures, managing physical facilities, utilizing human resources, and developing techniques for encouraging students to be self-managing. Evaluation methods, questionnaires and observation indicated a favorable change in teacher behavior. The effects of the inservice program for teachers indicated little or no affect on student attitude and independent work habits. (Appendixes of related program material and a …


Magnetic And Thermometric Properties Of Na3[Ce(C7h3no4)3] ·15h2o In The Millikelvin Range, Richard A. Webb, J. C. Wheatley Oct 1972

Magnetic And Thermometric Properties Of Na3[Ce(C7h3no4)3] ·15h2o In The Millikelvin Range, Richard A. Webb, J. C. Wheatley

Faculty Publications

Measurements of the 16-Hz susceptibility of a powdered Na3[Ce(C7H3NO4)3] · 15H2O (CDP) sample, in the shape of a right-circular cylinder with diameter equal to height, have been made as a function of the Johnson noise temperature TJ of a resistor in the range 2 to 20 mK. Pure liquid 3He was used for thermal contact between the CDP and the noise thermometer in a demagnetization cell. The results are compared with similar data for cerium magnesium nitrate (CMN). CDP appears, like CMN, to have an anomalously …

X-Ray Diffraction Studies On Liquids At Very High Pressures Along The Melting Curve Ii. Sodium, Keith H. Brown, J. Dean Barnett Sep 1972

X-Ray Diffraction Studies On Liquids At Very High Pressures Along The Melting Curve Ii. Sodium, Keith H. Brown, J. Dean Barnett

Faculty Publications

Coherent x-ray diffraction patterns for liquid Na have been extracted from measured patterns at 0.5, 7.5, 17, and 43 kbar along the melting curve. The experimentally determined liquid structure factor and resulting radial distribution function are given at each pressure. The position of the principal x-ray intensity peak is reproducible to within 0.5% and shows shifts of the order of 12%. The resulting nearest neighbor distance in the radial distribution function also shifts 12% but is reproducible only to approximately 2%. The distribution functions obtained at points along the melting curve suggest a simple dimensional compression or scaling; however, a …


X-Ray Diffraction Studies On Liquids At Very High Pressures Along The Melting Curve. I. Methods And Techniques, Keith H. Brown, J. Dean Barnett Sep 1972

X-Ray Diffraction Studies On Liquids At Very High Pressures Along The Melting Curve. I. Methods And Techniques, Keith H. Brown, J. Dean Barnett

Faculty Publications

A technique using the tetrahedral anvil high-pressure x-ray system has been developed to extract coherent x-ray intensity patterns of liquids near melting from measured scattering curves in the presence of high-background counts. Radial distribution functions for liquids along the melting curve to pressures of at least 50 kbar can be obtained. At each pressure scattering curves are recorded for the liquid and solid on opposite sides of the melting curve and a subtraction is made to eliminate background and incoherent scattering. Theoretical estimates of the thermal diffuse scattering from the solid are added to the appropriately corrected difference patterns to …

Β-Delayed Proton Decay Of 9c, David D. Allred, John E. Esterl, J. C. Hardy, R. G. Sextro, Joseph Cerny Jul 1972

Β-Delayed Proton Decay Of 9c, David D. Allred, John E. Esterl, J. C. Hardy, R. G. Sextro, Joseph Cerny

Faculty Publications

The delayed-proton spectrum following the β decay of 9C (t1/2=126.5±1.0 msec) was found to consist primarily of a continuum extending from 13 to 1.5 MeV, the latter being the lowest energy observed. In addition to the previously observed peaks at 9.28 and 12.30 MeV (C.M.), possible peaks between 3 and 7 MeV have been tentatively identified.

Wells And Streams: Relationship At Law, Peter N. Davis Apr 1972

Wells And Streams: Relationship At Law, Peter N. Davis

Faculty Publications

Groundwater constitutes one of the major sources of water for municipalities, irrigators, and rural dwellers. Conflicts between groundwater users are bound to arise from time to time, as is evidenced by a recent Missouri case, Higday v. Nickolaus, discussed elsewhere in this issue.' Such conflicts may increase in frequency in the future as the demand for groundwater increases. Although a majority of cases will involve allocation of groundwater between users of that class of water, many groundwater diversion cases will involve adverse effects on the flow of water in streams. It is –to the latter situation that this article is …


On The Mechanism Of Low-Temperature Termolecular Atomic Recombination, Russell T. Pack, Richard L. Snow, Wesley D. Smith Jan 1972

On The Mechanism Of Low-Temperature Termolecular Atomic Recombination, Russell T. Pack, Richard L. Snow, Wesley D. Smith

Faculty Publications

A simple theory of gas-phase termolecular atomic recombination kinetics is presented which treats the bound-complex (BC) mechanism in a fashion which parallels the Roberts, Bernstein, and Curtiss resonance theory of the energy-transfer (ET) mechanism. The ET rate constant has a low temperature maximum, but the BC rate constant does not. The contributions of the two mechanisms to the low-temperature recombination of hydrogen atoms, with He, Ar, and H2 as third bodies, are estimated and compared. The presence (absence) of a low-temperature maximum in the observable total rate constant is determined by absence (presence) of bound vibrational levels of the hydrogen-third …

An Assessment Of The Differences Between High And Low Achieving Students. Final Report, Ralph Scott, Jon A. Ford

Faculty Publications

Primarily a longitudinal and quantitative analysis of achievement functioning; this experiment sought to identify factors which promote or impair the learning of individual children. The 683 Junior High students were divided into one of eight groups according to sex; race and whether their seventh grade Iowa Test of Basic Skills Composite score was above or below that expected from their Kindergarten Metropolitan Readiness Test performance. The incidence of males and females making unexpected gains (Ups) or losses (Downs) was approximately the same; but a significantly greater proportion of black children made greater than expected achievement gains. Thirty-three Up Ss were …

High-Pressure Equation Of State For Nacl, Kcl, And Cscl, Daniel L. Decker Jul 1971

High-Pressure Equation Of State For Nacl, Kcl, And Cscl, Daniel L. Decker

Faculty Publications

A calculation of the equation of state for NaCl from a Mie-Grüneisen equation was repeated using more accurate values of the zero-pressure compressibility. It was also extended to KCl and CsCl. An analysis of this approach to pressure calibration indicates that it will yield pressures with about the same accuracy as can be presently achieved by experimental measurements above 25 kbar, and thus furnishes a temporary practical pressure scale.

Lamb-Mössbauer Factor Of Sodium Ferrocyanide, Daniel L. Decker, L. E. Lortz Feb 1971

Lamb-Mössbauer Factor Of Sodium Ferrocyanide, Daniel L. Decker, L. E. Lortz

Faculty Publications

Using a set of commercially prepared sodium ferrocyanide absorbers enriched to 91.2% Fe57 the Lamb-Mössbauer factor was measured to be 0.28±0.03. The thickness of Fe57 for these absorbers was measured using x-ray absorption techniques and was found to be considerably smaller than that advertised by the manufacturer even after correcting for the size of the ferrocyanide particles in the absorbers.

Theories Of Water Pollution Litigation, Peter N. Davis Jan 1971

Theories Of Water Pollution Litigation, Peter N. Davis

Faculty Publications

The common law has traditionally provided the rules that govern relationships among landowners in their use of watercourses. These rules are embodied in the eastern United States in the doctrine of riparian rights, which addresses itself both to water quantity, and to water quality. Persons complaining of pollution of waters abutting their lands have, in addition to redress by complaint to the state pollution control agency, redress by lawsuit against the alleged polluter. This common law supplements the body of statutory law regulating the waters of the state for the benefit of the people.
