Livestock Feeding: What Small Feeders Are Doing In Nebraska, Allen C. Wellman, Jeffrey L. Jorgensen Jun 1972

Livestock Feeding: What Small Feeders Are Doing In Nebraska, Allen C. Wellman, Jeffrey L. Jorgensen

University of Nebraska-Lincoln Extension: Historical Materials

Specific data about how smaller Nebraska feeders are marketing their livestock has not been readily available. This is a report of a survey which was conducted in order to analyze the marketing practices of these livestock feeders and the changes in their marketing practices over a five-year period.

The objectives of this study are (1) to determine whether direct sales of fed cattle to packers is increasing in Nebraska as national trends indicate, (2) to obtain a general picture of the current state of the livestock marketing system for small feeders in Nebraska, and (3) to forecast possible trends for …

Professor Leo Moser -- Reflections Of A Visit, Walter E. Mientka Jun 1972

Professor Leo Moser -- Reflections Of A Visit, Walter E. Mientka

Department of Mathematics: Faculty Publications

Professor Leo Moser' was known throughout the Mathematical Community as a significant researcher and excellent lecturer. I first met Leo during the Summer Research Institute in the Theory of Numbers held at the University of Colorado in 1959. After talking with him and hearing his lectures during the Institute, I felt that arrangements would have to be made in the near future for a visit to Nebraska. During the academic year 1962-63 while Professor Moser was on a lecture tour for the MAA, I invited him to present two research lectures to the Nebraska Section on May 3 and 4, …

Three-Configuration Matching-To-Sample In The Pigeon, Alan Kamil, Robert A. Sacks May 1972

Three-Configuration Matching-To-Sample In The Pigeon, Alan Kamil, Robert A. Sacks

Papers in Behavior in Biological Sciences

Pigeons were trained on a zero-delay matching-to-sample procedure during which only three of the four possible stimulus configurations were presented. Subsequently, all birds were exposed to all four configurations as a transfer test. A high degree of negative transfer from the three training configurations was obtained in Experiment 1. The results of Experiment 2 indicated that three-configuration training produced differential position-preference effects. During the transfer test, responding after one sample stimulus was apparently based on position, while responding after the other sample was based on color.


Schottky Defects In Alkali Halides, Paul D. Schulze, John R. Hardy Apr 1972

Schottky Defects In Alkali Halides, Paul D. Schulze, John R. Hardy

John R. Hardy Papers

The method of lattice statics and the deformation-dipole model have been applied to Schottky defects in ionic crystals in approximations higher than zero order. For an isolated vacancy, all host-lattice-ion potential energy functions for short-ranged repulsive and Coulomb-defect forces were expanded to terms quadratic in the displacements and dipole moments, and the resulting forces were allowed to act on the first and/or second neighbors to the vacancy. The zero-order Coulomb force was allowed to act on the remainder of the host-lattice ions past first and/or second neighbors. The vacancy and Schottky-pair-formation energies in the 12 Na, K, Rb halides have …


The Role Of Anxiety And Arousal Attribution In Cheating, Richard A. Dienstbier Apr 1972

The Role Of Anxiety And Arousal Attribution In Cheating, Richard A. Dienstbier

Department of Psychology: Faculty Publications

Previous research indicated that anticipating arousal symptoms (rather than benign) from a placebo pill reduced inhibiting emotion in men, resulting in more cheating. The effect did not occur for women. Using 180 males, Study I tested whether the placebo effect was due to mere attention to arousal symptoms, or whether attribution to the pill was required. In the placebo- attribution condition the arousal placebo facilitated cheating (p < .02). The effect did not occur for symptom-attention controls who received no pill, and the conditions differed (p < .02).Study II tested whether women failed to respond to the placebo manipulation due to higher anxiety. Under one of four stress levels, each of 240 women received the benign or arousal placebo. More cheated with the arousal placebo only under low stress (p <.035), and stress conditions differed (p < .025). The interaction of attribution manipulations with the conflicting emotions of the cheating situation is discussed.


Lyly's Midas As An Allegory Of Tyranny, Stephen S. Hilliard Apr 1972

Lyly's Midas As An Allegory Of Tyranny, Stephen S. Hilliard

Department of English: Faculty Publications

John Lyly's Midas is structured in terms of traditional allegorizations of the Ovidian myth that represent Midas as an avaricious and ignorant tyrant. Lyly is thus concerned with a theme popular in the public theater, but he treats it in allegorical manner distinctive in its focus on theme rather than character or action. The play first portrays Midas's mistaken choice of a private end, the accumulation of wealth for its own sake and as a means of financing lechery and aggression, then suggests the difficulties this causes in the governing of his kingdom. The episode in which Midas judges the …


The Social And The Causal Concepts Of Responsibility, Nelson T. Potter Jr. Apr 1972

The Social And The Causal Concepts Of Responsibility, Nelson T. Potter Jr.

Department of Philosophy: Faculty Publications

The causal and the social concepts of responsibility share the notions of (a) a causal agent, and (b) some effect for which the agent is a cause. But William L. Blizek argues that the social concept has an additional element not shared by the causal concept: that of an adjudicator, someone who imputes responsibility. Thus he writes, “social responsibility is not a relationship between cause and effect, but a relationship between an agent and some consequence, as prescribed by an adjudicator.” He points out that our judgments of the different kind of social responsibility may change, as the society changes; …


Iterative Nonlinear Pulsations In Massive Stars. I. The Iterative Approach, Norman R. Simon Mar 1972

Iterative Nonlinear Pulsations In Massive Stars. I. The Iterative Approach, Norman R. Simon

Norman R. Simon Papers

We consider "soft" pulsations in a massive main-sequence star, and attempt to investigate the regime in which the motion is nonlinear but not strongly so. The star is assumed to begin its finite amplitude pulsation in the linear fundamental mode. The adiabatic equation of motion is expanded (schematically) to third order in the radial amplitude, and a solution sought in the form of a Fourier series over an interval which turns out not to deviate much from the fundamental period of pulsation. Arguments based on the size of successive terms are used to isolate a set of five equations, the …


Iterative Nonlinear Pulsations In Massive Stars. Ii. Terms Up To Second Order, Norman R. Simon Mar 1972

Iterative Nonlinear Pulsations In Massive Stars. Ii. Terms Up To Second Order, Norman R. Simon

Norman R. Simon Papers

An iterative technique is used to calculate radial adiabatic pulsational amplitudes up to second order in a very massive main-sequence star. The second order terms are displayed, and discussed in detail. A possible connection between the qualitative structure of these terms and the absence of observed massive main-sequence pulsators is suggested. Finally, we discuss the resonance properties of the present model and consider their effect on the iterative calculation.


Resonance Effects In Polytropes, Norman R. Simon, V. K. Sastri Mar 1972

Resonance Effects In Polytropes, Norman R. Simon, V. K. Sastri

Norman R. Simon Papers

Second-order anharmonic pulsational amplitudes are investigated for a variety of polytropic models. It is found that the qualitative behavior of these amplitudes is decisively affected by the existence of resonances - this remaining true even when a given model is itself not in a resonant situation. An empirical asymptotic formula is given for the normal mode spectra of polytropes. The question of resonances is discussed for real stars, and a suggestion made for classifying Cepheid-type pulsators on the basis of resonant properties. Finally, invalid numerical results from an earlier work (Simon, 1971) are corrected in the Appendix.


Depth Perception As A Function Of Age, Benjamin Bell M.D., Ernst Wolf Ph.D., Charles D. Bernholz Mar 1972

Depth Perception As A Function Of Age, Benjamin Bell M.D., Ernst Wolf Ph.D., Charles D. Bernholz

University of Nebraska-Lincoln Libraries: Faculty Publications

Binocular depth perception was investigated in 164 healthy Ss of the Normative Aging Study, in connection with a model of ocular aging which explains change in the dioptric media in the forties on the basis of mechanical change and later change in the retina on the basis of metabolic change. A modified Verhoeff stereopter was used. The results showed a marked diminution to make stereoptic judgments occurred in the forties decade. This is in accordance with the model. In a companion paper, retinal field shrinkage will be explored as an illustration of later metabolic age change.


A Modified Belief Theory Of Prejudice Emphasizing The Mutual Causality Of Racial Prejudice And Anticipated Belief Differences, Richard A. Dienstbier Mar 1972

A Modified Belief Theory Of Prejudice Emphasizing The Mutual Causality Of Racial Prejudice And Anticipated Belief Differences, Richard A. Dienstbier

Department of Psychology: Faculty Publications

The belief theory of prejudice introduced by M. Rokeach stated that racial prejudice is the result of the anticipation of belief differences. The unidirectional causal relationship implied is criticized as oversimplified. Research, supporting the belief theory is examined, with conceptual and experimental deficiencies noted. A new formulation is proposed which emphasizes mutual causality between racial prejudice and anticipated belief differences. Two studies supporting that view are presented in which belief communications were presented as tape-recorded interviews or speeches, with the race and social class of the communicator first having been manipulated. The interrelationships between communicator’s race, specific communication topic, and …

Good Practice Statements−Developing Guidelines For The Safe And Efficient Use Of Pesticides, Harold S. Stein Jr. Mar 1972

Good Practice Statements−Developing Guidelines For The Safe And Efficient Use Of Pesticides, Harold S. Stein Jr.

Vertebrate Pest Conference Proceedings: 5th (1972)

Because pest control, vertebrate and invertebrate, is an applied science, a disciplined technology is mandatory. The National Pest Control Association, through its technical committees, is developing guidelines for the safe and efficient use of pesticides and for the execution of specific forms of pest control. These guidelines known as "Good Practice Statements" not only reveal a methodology utilizing the cooperative efforts and experiences of commercial pest control operators, representatives of the scientific community, and specialists from pertinent governmental regulatory agencies, but in them-selves as physical documents add to the total expertise of everyone connected with the problems and responsibilities of …


The Influence Of Attractants And Repellents On The Feeding Behaviour Of Rattus Norvegicus, J. O. Bull Mar 1972

The Influence Of Attractants And Repellents On The Feeding Behaviour Of Rattus Norvegicus, J. O. Bull

Vertebrate Pest Conference Proceedings: 5th (1972)

Poison baits are extensively used for commensal rodent control; considerable folk lore exists regarding the use of additives to induce rodents to come to and eat poison baits. This paper describes a rational evaluation of attractants and the influence of different odours in inducing Rattus norvegicus to feed at given locations. The influence of certain repellents was also examined. Tests consisted of attempts to induce rats to feed at non-preferred sites or to repel them from preferred sites. Place preference was the dominant factor in feeding by rats, and odours failed to influence feeding activity significantly.


Keynote Address - Vertebrates: A Resource Needing Management, Donald A. Spencer Mar 1972

Keynote Address - Vertebrates: A Resource Needing Management, Donald A. Spencer

Vertebrate Pest Conference Proceedings: 5th (1972)

A veritable storm of concern for wildlife - approaching biotechnology - is currently sweeping the nation. Some of this concern has a sound basis. But the very best of ideas and programs can be carried so far that they become irrational. We appear to be driving head-on into irrational actions with respect to environmental good housekeeping. The vegetative cover in the United States has changed markedly as the result of Man's occupancy, reducing the habitat on which some wildlife species depend and greatly enhancing that of others. Competition, a no-holds-barred struggle, continues unabated between all living things for the finite …

Echinococcus Vogeli Sp. N. (Cestoda: Taeniidae) From The Bush Dog, Speothos Venaticus (Lund), Robert L. Rausch, J. J. Bernstein

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Echinococcus vogeli sp. n., from a bush dog, Speothos venaticus (Lund), captured in the Province of Esmeraldas, Ecuador, differs morphologically from the three species of Echinococcus recognized as valid. E. vogeli sp. n. is distinguished from E. granulosus (Batsch 1786) by its larger rostellar hooks, different proportions of the strobila, tubular, sac-like gravid uterus, and different arrangement of the female genital ducts. from E. multilocularis Leuckart 1863 by its larger rostellar hooks, different proportions of the strobila, position of genital pore, and greater number of testes; from E. oligarthrus (Diesing 1863) by different proportions of the strobila, position of genital …


Testing A Planning And Control Model In Nonprofit Organizations, Charles A. Reimnitz Mar 1972

Testing A Planning And Control Model In Nonprofit Organizations, Charles A. Reimnitz

Department of Management: Faculty Publications

This study utilizes a planning and control model abstracted from the conceptual framework of general management knowledge to test the relative efficiency of administrators in three educational service organizations. The hypothesis that subordinates' perceptions of administrators' relative proficiency will be a function of the administrators' education, training, experience, and conscious use of management techniques appears to be substantiated.

Eutrophication Factors In North Central Florida Lakes, H. D. Putnam, Patrick L. Brezonik, Earl E. Shannon

United States Environmental Protection Agency: Publications

A small Florida lake has been receiving a regimen of nutrient addition equivalent to 500 mg/m3-yr N and 43 mg/m3-yr P since 1967. Data has been accumulated through 1969. The effect on the lacustrine ecosystem of various biogenes includes production by primary producers, species diversity of plankton and certain production estimates at the secondary trophic level using natural populations of planktivorous fish. Plankton production using isotopic carbon is ca. 58 grms/m2-yr; Species diversity is slowly changing to a mixed chlorophycean and yellow-green. Biomass of benthic green filamentous types has increased slightly. Nutrient addition has …

Residential Environment Studies Relevant For Research Programs. An Annotated Bibliography. Economic, Aesthetic And Environmental Aspects Of Family Housing, Florence S. Walker

Nebraska Agricultural Experiment Station: Historical Research Bulletins

At the time NCR-54 Committee was activated in 1966, the membership was charged with recommending new directions for housing research by home economists and others associated with Agricultural Experiment Stations. Basic to this charge, the committee determined to compile a list of housing research publications which had had an impact on the teaching and research responsibilities as perceived by the committee members. The compilation took the form of abstracts of research on selected aspects of housing: i.e., design and aesthetic, physical-physiological and socioeconomic, as well as influential general studies.

An Argument For The Open Ocean Siting Of Coastal Thermal Electric Plants, Clarence M. Tarzwell Jan 1972

An Argument For The Open Ocean Siting Of Coastal Thermal Electric Plants, Clarence M. Tarzwell

United States Environmental Protection Agency: Publications

A great deal of research is yet to be done before we will definitely know all the effects of thermal electric generating plants. It is evident, however, that the chlorination of the intake water is definitely lethal to a high percentage of planktonic and other organisms; that thermal shock is detrimental to some of the more sensitive forms; that the continued exposure to high temperatures after thermal shock is lethal to many forms, especially the zooplankton; that the screening and turbulence in such plants is lethal to larval fishes and several invertebrates, and that immense amounts of waters are put …
