Changes In The Midgut Of Female Amblyomma Americanum As A Result Of Feeding Upon Hosts Expressing Different Levels Of Acquired Anti-Tick Resistance, Mildred E. Voss-Mccowan

Theses and Dissertations

Previous studies have demonstrated that host acquired resistance resulted in reduced numbers of engorged ticks, restricted engorgement, reduced numbers and viability of ova, longer duration of feeding, and in some instances, the death of the tick. It is currently not understood how ticks are adversely affected by feeding on hosts expressing acquired tick resistance.

Examination of the midgut and diverticulae of adult female Amblyomma americanum allowed to engorge on guinea pigs acquiring and expressing tick resistance revealed changes in the gut epithelium as well as in the cellular composition of the blood meal. Engorging females were removed from hosts at …

The Relationship Of Obsessive-Compulsive Characteristics To Impression Accuracy And Perceptions Of Self And Others, Jill M. Plevell-Omdahl

Theses and Dissertations

The identification of methodological and statistical difficulties in previous impression accuracy research has necessitated that the role of personality in impression accuracy be reinvestigated. The present research addressed: (1) the impact of obsessive-compulsive personality traits on impression accuracy; and (2) subject perceptions of actual self, ideal self, others, and others' perceptions of them.

This study utilized a 2 x 2 x 2 design. Independent variables included: (1) judge vs. observer status; (2) high vs. low obsessive-compulsive traits; and (3) first vs. second session. Dependent variables included subject ratings on the OSCARS (Versions 1-4), designed to measure the obsessive-compulsive tendencies in …

Music As Communication: A Rhetorical Perspective Based On Susanne Langer's Theory Of Aesthetic Symbolism, Deanna D. Sellnow

Theses and Dissertations

The purpose of this dissertation is to create a rhetorical perspective by which to understand and analyze music as aesthetic communication. Specifically, this study extends Susanne Langer's theory of aesthetic symbolism as it relates to music as a mode of communication. Once the rhetorical perspective for analyzing music as communication has been depicted, the perspective is operationalized to analyze music from two contemporary social movements in the United States. The music analyzed in this dissertation comes from the Neo-Nazi Skinhead movement and the New Age movement. By approaching music as aesthetic communication in this way, the reader is able to …

Student's Perceptions And Experiences Of Sexual Harassment At The University Of Tennessee At Chattanooga, Wendy W. Davis

Honors Theses

This research was conducted to examine students' perceptions and experiences of sexual harassment in higher education. The study was designed and administered in such a way as to address four concerns which have not been effectively handled in previous studies. These specific concerns are as follows: (a) the nonrandom selection of students, (b) the exclusion of males in samples, (c) the limited number of research methods used, and (d) the lack of a standardized definition for sexual harassment. The first three issues focus on the need to obtain representative samples of the college population.

Consumption Of Solid Food By Suckling Pigs: Individual Variation And Relation To Weight Gain, Edmond A. Pajor, David Fraser, Donald L. Kramer

Feeding Behavior Collection

Individual daily consumption of supplementary solid food ('creep feed') was measured from Day 10 to weaning at Day 28 for 39 piglets in four litters, and its relationship to body weight and weight gain up to Day 42 was investigated. Individual consumption was measured by combining the weight of the feed removed from the dispensers (monitored electronically) and a video image of piglet activity at the feeder. Creep feed consumption varied greatly, both between and within litters. On average, pigs began feeding on Day 12 (range Day 10-28), intake was relatively low (usually < 5 g day ^‒1) until Day 20 but increased …

Use Of A Commercially Available Flight Simulator During Aircrew Performance Testing, S. A. Shappell, B. J. Bartosh

Publications

Investigations of aircrew sustained operations (SUSOPS) have been criticized for employing tasks with no apparent external validity. Because measures obtained directly from aviators flying high-performance aircraft are difficult to obtain, a laboratory compromise is needed. High-fidelity flight simulators used for aircrew training offer the most realistic simulation, but their availability is limited. Personal computer-based flight simulators may provide adequate simulation in, the laboratory at a reasonable cost. This report describes a representative research protocol using a commercially available flight simulator during a simulated aircrew SUSOP.

The Organizational Impact Of Smoke Break Management In Strategic Air Command, Glenn G. Hinken

Theses and Dissertations

This study investigated the organizational impact of smoke break management in Strategic Air Command. Analysis of data from a survey questionnaire showed that although the smoking and smoke break issues touched the majority of the people in SAC and almost every smoker surveyed reported taking smoke breaks, just 27 percent of respondents reported their organization had a smoke break policy. Most of these respondents indicated the policies were lenient in terms of regulating the time and duration of the breaks. Smokers reported spending an average 41.09 minutes per day taking smoke breaks. This figure differed significantly from the time smokers …

Dysfunctional Attitudes, Life Stress And Coping Processes, Deborah Desalliers

Loma Linda University Electronic Theses, Dissertations & Projects

The findings of recent investigations earmarked chronic daily stressors as being highly related to stress levels. In addition, researchers are promoting a more integrative model of stress. The stress response is no longer thought of in strictly linear terms, i.e. an event causes stress. Rather, cognitive factors, existing within the human mind itself, strongly influence our coping processes and the chronic stress we experience.

Canonical correlation analysis was used to study how dysfunctional attitudes, a negative cognitive factor, were related to individuals' daily hassles and coping processes. An increase in dysfunctional attitudes was found to correspond to an increase in …

Temporal Contiguity As A Defining Feature Of The Terms Reinforcer And Discriminative Stimulus: A Survey Of Journal Editorial Staffs, Julie Ann Fillhard

Masters Theses

Behavior analysis is a science that requires a consistent set of terms to describe independent and dependent variables and the relations between them. However, a review of literature indicates that behavior analysis is plagued by terminological inconsistencies, even with such basic terms as reinforcer and discriminative stimulus.

In the present study, 193 journal editorial staff members were surveyed to determine the importance of temporal contiguity in defining the terms reinforcer and discriminative stimulus. Eighty-seven editors (45%) responded to the survey which described two hypothetical scenarios and contained a series of questions relevant to each.

The results of the study indicate …

The Effects Of Goal Setting And Supervisory Feedback On Staff Performance In A Human Service Setting, Michael D. Mack

Masters Theses

Goal setting and supervisory feedback were examined to determine their relative effects on the performance of direct care staff. The performance of five staff from a day treatment program for developmentally disabled adults was measured. The specific performance measure of interest was staff implementation rates of daily training programs with clients. The results demonstrated that adding performance feedback to goal setting had minimal impact on staff performance. Yet, goal setting alone as an initial technique was effective in improving the performance of staff. Unfortunately, the long-term effects of goal setting alone may be less desirable than these initial data indicate. …

The Effects Of Daily And Weekly Supervisor Feedback On The Performance Of University Clerical Staff, Christopher Benjamin Turla

Masters Theses

Weekly and daily feedback were compared. Employees self-recorded the quantity and type of tasks completed throughout the study. In feedback condition 1, the supervisor delivered feedback once a week to two employees and everyday to three employees. In feedback condition 2, feedback frequencies were switched such that employees who first received weekly feedback received daily feedback, and employees who first received daily feedback received weekly feedback. Job satisfaction was measured before …

The Drama Of Alienation: An Interpersonal Examination Of Edward Albee's The Zoo Story And Sam Shepard's Buried Child, Lisa Arnold

Theses and Dissertations

This study examined alienation from an interpersonal communication perspective in order to find a connection between aspects of alienation and interpersonal communication.

Alienation occurs at two levels according to scholars in sociology and psychology. At the social level, one's culture influences behavior in interpersonal relations. At the psychological level, one's perception of self worth influences interpersonal relations. This study used Srole's five aspects of alienation (isolation, estrangement, powerlessness, unpredictability, and meaninglessness) to analyze interpersonal relationships between those alienated on both levels.

Two plays were chosen to exemplify how alienated people need close interpersonal communication. The Zoo Story, by Edward Albee …

The Relation Between Maternal Behavior And Childrearing Goals And Child Outcomes In Low-Income Black Children, Dawn D. Wimbush

Psychology Theses & Dissertations

The present study examined the relation between maternal goals and practices and preschool children's cognitive development and behavioral compliance. Fifty low-income Black mothers of three- to five— year-old children were interviewed and completed several questionnaires that assessed childrearing goals and practices. The HOME, a measure of maternal stimulation was also assessed. Children were administered the McCarthy Scales of Children's Abilities and an achievement test. Child compliance to maternal requests was observed in the home. Considerable diversity was found in maternal childrearing goals. For the most part, maternal goals were not related to child outcomes; however, indirect-internal techniques (Sears, Maccoby, & …

Gender Effects On Recall, Clinical Judgement And Treatment Recommendations For A Combination Of Major Depression And Alcohol Dependence Symptoms, Jodi L. French

Psychology Theses & Dissertations

This study investigated the effect of client gender on several aspects of clinical decision-making processes and clinical judgement when a client presented with a combination of depressive and alcohol-dependent symptoms. Forty-four male and 44 female clinicians, who came from various mental health disciplines (i.e., psychology, social work, counseling, nursing, and psychiatry), volunteered to participate as subjects.

The subjects were assigned to hear one of four audiotapes (two male tapes and two female tapes) in which mock clients gave the same initial presentation of symptoms and problems. After listening to the tapes, the clinicians were asked to engage in a number …

Determinants Of Feedback-Seeking Behaviors, Melinda J. Montgomery

Psychology Theses & Dissertations

The purpose of the present research was to evaluate the effects of the level of task difficulty, the value of the goal, and the amount of effort required to obtain feedback on the frequency of feedback-seeking behaviors (FSB). The design was a 2 (task difficulty) x 2 (goal value) x 2 (effort) x 3 (day) mixed model analysis of variance. Eighty undergraduates were randomly assigned to one of eight experimental conditions.

Contrived Versus Natural Reinforcers In The Acquisition Of A Verbal Repertoire By Adult Learners, Lisa Ann Leblanc

Dissertations

Previous research suggests that by making classroom contingencies for verbal responding more like those in the natural environment, i.e., by using motivative variables to evoke verbal responses which are followed by specific actions on the part of listeners, verbal repertoires can be taught more effectively to children and language impaired individuals. The present study examines the role of specific versus generalized conditioned reinforcement following adult students' question-asking on the acquisition of a verbal repertoire in a classroom setting and on the generalization of this repertoire to a more natural verbal environment.

Subjects were 32 university students in two American Sign …

The Effects Of Quality Contingent Extrinsic Rewards On Intrinsic Motivation, Kimberly Ann Filler O'Connor

Masters Theses

Although many studies have shown that performance-contingent rewards increase performance quantity, few have examined whether quality contingent rewards increase quality. One objective of the present study was to determine whether quality contingent rewards would improve quality.

A second, independent objective was to determine whether extrinsic quality contingent rewards would decrease a person's intrinsic interest in and quality performance of a task following termination of those rewards. To date, no other studies have examined the effects of quality contingent rewards on intrinsic interest and quality performance.

The results indicated that quality performance-contingent rewards do improve quality. Quality contingent rewards increased quality …

The Effects Of Self-Esteem, Performance Feedback, And Behavioral Verifiability On Self-Serving Biases, Diana C. Slatopolsky

Master's Theses

The present study examined the psychological processes underlying the self-serving bjas, the tendency to portray one's own qualities as more favorable then those of others. Subjects were asked to predict future success on a behavioral task for themselves and for the average student at their university after receiving performance feedback on the same task. It was proposed that self-enhancing predictions would be moderated by subject's self-esteem (high or low), the verifiability of task performance (high or low), and performance feedback (success or failure). The results revealed that subjects with high self-esteem displayed a self-serving bias regardless of performance verifiability or …

Predictors Of Change For Parents Who Perceive Improvement In Their Family Functioning Following A Parent-Training Program, Linda Gayle Moore

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of the present study was to determine if perceptions of improved family functioning following a behavioral parenting program could be predicted by educational background, income, and pretest knowledge of behavioral principles. Subjects for the study were parents of elementary-school-aged children who volunteered for the parenting classes. Parents who perceived their families as dysfunctional, as measured by the pretest FACES II, were selected as subjects for the study. Parents whose perceptions of their families improved after the parenting class were then compared with parents who did not perceive improvement in their families on the predictor variables.

The results demonstrated …

The Development Of An Instrument For The Assessment Of Obesity-Related Cognitions, David E. Christian

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This dissertation involved the design and validation of the Obesity Cognitions Inventory (OCI) which was intended to quantify cognitions associated with obesity. An initial pool of 117 items was refined through expert ratings, a pilot test involving 59 subjects, and a major test and validation using 217 subjects.

The resulting 56-item instrument contains scales measuring five types of cognitions: Personal Control, Dietary Restraint, Cost-Benefit Beliefs, Health Knowledge, and Self-Concept. Test-retest reliabilities for these scales range from .69 to .83 and Cronbach alphas range from .57 to .82. Concurrent criterion validity of the OCI was assessed through two methods (a) correlations …

Using Direct Instruction To Teach Compliance To Seriously Noncompliant Students, Hans M. Michielsen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This research study investigated the effectiveness of a direct instruction program (Treatment 2) for increasing compliance with teachers' instructions in students for whom manipulation of conventional antecedent stimuli and consequences (Treatment 1) had not resulted in adequate compliance. Five students participated in this study. A multiple baseline design across participants was used to evaluate treatment effectiveness. Introduction of Treatment 2 was followed by an increase in compliance by all five participants. The relationship between compliance and other appropriate classroom behaviors, as well as the relationship between compliance and qualitatively good and qualitatively poor instructions, was also investigated. Those relationships were …
