The Role Of Cognitive Differentiation In Conceptual Systems Theory, Mary Flume

Student Work

A cognitive approach to theory and research in personality proposes that individuals develop relatively enduring cognitive schemas for experiencing and organizing their .social world. Cognitive schemas are templates through which information is filtered or transformed.

It may be understood that cognitive personality theory emphasises the structure of cognition rather than its content. Such an emphasis is based on the assumption that structural variables are relatively enduring and invariant across situations, whereas the content of personality is expected to fluctuate markedly. Cognitive personality theory should provide the researcher with an efficient basis for describing the actions of a person and lead …

Memory For Persons, Encounters And Sex, William Sturgill

Student Work

Recognition of previously seen persons and recall of the circumstances of their encounter were tested in a situation' where subjects were unaware of the subsequent recognition task. Subjects encountered four: persons, one of each sex. in. two separate encounters. Prior to a lineup one week later, only 51 subjects (N = 145) failed to' recall either the number and/or the sex of the persons encountered, while only 28. correctly recalled both the number and sex and that it was two different persons in each encounter. Results from the lineup confirmed, previous suggestions that subjects (N = 155) are better able …

The Influence Of Press Variables And The Measurement Of Show Through Of Paper, William Nourse

Theses

Several fundamental questions are discussed relating to show through of ink on paper. These questions relate to (a) the significance of ink and press variables in regard to show through; (bj the correlation between the light reflectivity of an ink film thickness and the show through of the ink; (c) the correlation between the percentage of pigment in the ink, and the show through of ink; (d) the interchangeability of various instruments for the measurement of show through. Data is obtained using a standard offset ink in combination with several different kinds of paper. Several, different known ink film thicknesses …

The Effectiveness Of Various Omission Training Procedures As A Function Of Reinforcement History, Mary Patricia Brockman

Student Work

This experiment analyzed the relative effectiveness of three forms of omission training (OT 20 sec, OT 5 sec, and gradual OT with a time-dependent criterlor) in reducing a bar press response following three different reinforcement histories. Thirty-six children between the ages of 4% and 11 years were initially trained to press a bar according to a VR 35 schedule of reinforcement. The different omission training conditions were introduced directly following the VR 35 baseline, following a lengthened history of VR, and following a DRL intervention condition designed to enhance the effectiveness of the OT condition.

Effects Of Polyox In Fountain Solution, Jacob Varughese

Theses

"Polyox" is a polymer of ethylene oxide. It is soluble in water and commercially available. The effects of Polyox in fountain solutions were studied and evaluated. The same concentration (one-half percent of Polyox in water) at different pH and blending times, was tested for physical properties and printability. The physical property tests made were of viscosity, surface tension and contact angle. The printability tests were conducted as roll-up, ability to clean up the plate, resistance to scumming, printing sharpness and resolution properties. The experiments were conducted under controlled press conditions and the properties of each test solution were reported. Roll-up, …

An Analysis Of Generalization In A Parent Training Program From A Laboratory To Home Setting, Carol Mindell

Student Work

A mother was trained in a structured laboratory setting, through written and verbal instructions and daily verbal feedback, to modify specific components of her attention to her 4-yr-old daughter’s behavior during an instruct ion-following task. Examinations were made of the effectiveness of parent training in changing the mother’s behavior in the structured laboratory setting, as well as the extent of generalized change in mother’s responses in three other settings in which no training was conducted: 1) a similar structured period in the home, 2) a dissimilar unstructured period in the laboratory, and 3) a-dissimlar unstructured period in the home. The …

Solution Of The Transonic Potential Flow Equation By Finite Differences For The Hydraulic Analogy, Ewan Choroszylow

Theses

A numerical procedure is presented for the solution of the transonic potential flow equation around an isolated airfoil, for the hydraulic analogy. The numerical method used was the finite difference method, appropriately modified for a mixed elliptichyperbolic system of equations. Potential flow analysis was used, since for all practical purposes, the flow is inviscid throughout the flow field, except for wake regions and boundaries. The mixed finite difference scheme has proven to be an effective technique in the solution of elliptic and hyperbolic flow problems. For conditions near the wave propagation velocity (sonic velocity), difficulties have arisen in proper solution …

Situational Determinants Of A Crying Response: Their Interrelations With Cognitive Structure And Level Of Sex-Role Identification, Richard Paul Votta

Student Work

An attempt was made to assess the relationships between an individual's level of sex-role identification, degree of cognitive complexity or simplicity, and reported crying behavior. One hundred sixty six students from an introductory sociology class at the University of Nebraska at Omaha were administered three scales: the Bern Sex Role Inventory to assess their level of sex-role identification; the Millimet Rep Test (Version 1) to assess the degree of cognitive complexity, and the Votta Crying Scale-an instrument devised by the author to measure an individual's propensity to crying and the four major types of situations that will elicit the behavior. …

Developmental Aspects Of Nonverbal Communication, Richard Norris

Student Work

Developmental differences in encoding and decoding abilities were investigated in this study with subjects ranging from 5 years to 88 years of age. The 94 white, middle-class males and females were placed into five age groups. Subjects were asked to encode each of six emotional expressions, after which they were presented with three decoding tasks. The video tape mode required subjects to decode the same six common nonverbal expressions of emotion (i.e., anger, surprise, fear, happiness, sadness, disgust). A second decoding task consisted of four expressions (anger, fear, sadness, happiness) which were schematically depicted. Subjects' decoding of affect in a …

The Effects Of Values-Clarification Strategies On School Attitudes In Seventh Grade English, James C. Gaffney

Student Work

Educational systems are constantly faced with the question "What should students be taught?" Traditionally, the answer has been skills and concepts in basic subject areas used most often in life. Consequently, curricula center around facts about these subject areas, skills used by people in these areas, and concepts on which the subjects are based. New ways of presenting facts, skills, and concepts are continually being explored in the hope that students will internalize and apply them when the need arises. Student and parent involvement in the learning process, individualized instruction, high interest learning media, and various groupings of students in …

A Quantitative Method Of Pre-Setting The Ink Distribution Keys Of An Offset Duplicator Using A Photoelectric Estimating Unit, Martin Marino

Theses

The purpose of this study was to study the feasibility of quantitatively pre-setting the ink key distribution on an off-set press. Presently the pre-settings of the ink keys has been left to the pressmens' ability and experience. This, in many cases, involves much "trial and error" work along with lengthy makeready times. This study attempted to reduce makeready time by quantitatively pre-setting ink keys from data obtained from an estimating unit and use of a set of calibration curves. A photoelectric estimating unit was designed and constructed to read integrated densities of copy to be printed. There was one reading …

An Investigation Into The Emulsification And Determination Of Water In Lithographic Ink Emulsions, Thomas Saczawa

Theses

A study of the emulsification process of lithographic ink and water was conducted to investigate methods for determining the water content of lithographic ink and water emulsions. Experiments using infra-red spectroscopy and analysis of the hydroxyl and carbonyl absorption bands revealed several variables which must be considered when attempting to use infra-red spectroscopic methods for the determination of the water content of ink emulsions. These factors include the choice of pigment, (either transparent or opaque), the type of cell medium, and methods for dispersing added water into an ink. The initial problem encountered was a lack of reproducibility when attempting …

Image Intensification By A Low Level Light Exposure Before, During, And After An Image Exposure, Robert Rippstein

Theses

The purpose of this thesis is to study the effects on the shape and position of the characteristic curve due to a low level uniform exposure to white light. This was accomplished using a special camera which produced an image of a neutral density -wedge on a film strip. One half of this image was covered while the other half was uniformly exposed to a low level light exposure. In some cases the low level exposure was first applied to half of the film strip with the image exposure occurring second. The density differences between the two halves of the …

The Effect Of Patterned Visual Stimulation On Visual Activity And Feeding Behavior During The Feeding Period In Human Newborn Infants, Robert H. Anderson

Student Work

The relationship between patterned visual stimulation and behavior in newborn human infants has been studied in a variety of situations (Fantz, 196 3; Hershenson, 1965; Haith, 1965; Bruner, 1968; Salapatek, 1968; Wagner, 1972; Friedman 1972; Boismier, 1972). Typically, the effect of visual stimulation on the behavior of newborn infants during the feeding period has not been studied. This omission may in part be related to studies by Haith (1965) and Bruner (1968) who, in the investigation of the effects of visual stimulation on nonnutritive.sucking rates, concluded that newborns are virtually incapable of looking and sucking at the same time. Bruner, …

A Descriptive Study Of The Listening Skills Of Chief Probation Officers For The State Of Nebraska, Patricia A. Crosby

Student Work

Twenty years ago the place of listening in our educational system was neglected. Instruction in listening skills, even at the college level, was virtually nonexistent. Today, at all educational levels, training in listening is "coming of age." Listening is beginning to be recognized as an area of important communication skills. More important, it is being considered as fundamental skills which can and must be taught.
