Discriminative Stimulus Effects Of (+)-7-Oh-Dpat In Rats: Importance Of D3 Receptors, April J. Christian

Masters Theses

Despite the reported relatively high binding affinity of 7-OH-DPAT to dopamine D₃ receptors, results of recent investigations with the highly selective 03 receptor antagonist, PNU-99194A have questioned the importance of 03 receptors in the discriminative stimulus effects of 7-OH-DPAT. In the present study, sixteen male Sprague- Dawley rats (N=8/group) were trained to discriminate (+)- 7-OH-DPAT (0.03 mg/kg, sc) from saline in a two-lever operant procedure using a fixed-ratio 20 schedule of water reinforcement. After stable performance was established, substitution tests were conducted with the D₃-prefering agonist, (+)-PD-128907 and the psychostimulant cocaine. Additionally, antagonism were conducted with the …

Comparing Outcome Of Residential And Intensive Outpatient Treatment Services For Substance Dependence, Shawn E. Channell

Dissertations

The past 20 years have witnessed a significant increase in the number of published studies comparing inpatient with outpatient substance dependence treatment The majority of these studies have reported no benefit for those recipients receiving more intensive treatment However, the outpatient treatment investigated in these studies has typically been day treatment often involving 27 hours a week of participation, and not intensive outpatient treatment (IOP), which involves 12 or fewer hours of participation per week. Additionally, few published studies have compared alcohol and cocaine dependent populations. This study was designed to compare effectiveness of the residential and intensive outpatient levels …

Family And Child Psychosocial Functioning Of Infant Heart Transplant Recipients, Kimberly R. Freeman

Loma Linda University Electronic Theses, Dissertations & Projects

With the advancement of medical procedures, heart transplantation has become a viable alternative for infants born with congenital or acquired heart disease. Although these children are thought to experience much improvement in their overall physical functioning post-transplantation, the long-term psychological functioning of these children and their families is currently unknown. This study examines the long-term family functioning and psychosocial development of infant heart transplant recipients in comparison to children with congenital heart disease (CHD) and non-clinical control children. Results indicate that infant heart transplant recipients and their families experience fewer overall problems as compared to the CHD group, and more …

The Spiritual Dimension Of Social Work Practice In And Through Research, Education, And Life Experience, Pauline Kay Burthwick

Electronic Theses and Dissertations

This study was conducted among middle school principals in Virginia to determine their perceptions of job-related stress factors. The entire population of middle school principals (grades 6, 7, 8) was selected to participate in the study. The Administrative Stress Index was used to assess factors that cause principals stress on the job and to measure their stress levels. A demographic data form was used to collect data on the variables of age, gender, administrative experience, assistant principal support, student enrollment, adults supervised, percentage of students receiving free or reduced lunch, location of school, type of school, experience as a middle …

Predicting Post-Disaster Adjustment After The Red River Flood: An Analysis Of Resource Loss And Pre-Flood Preventative Behaviors, Holly J. Hegstad

Theses and Dissertations

The Conservation of Resources theory postulates that individuals will act to obtain, retain, or protect those resources that are of value to them (Hobfall, 1989). Natural disasters often result in depletion of resources, the extent of which has been found to be a robust predictor of post-disaster adjustment (Freedy, Hobfall, & Ribbe, 1994; Freedy, Shaw, Jarrel, & Masters, 1992; Norris & Uhl, 1993; Smith & Freedy, 1994). Three-hundred-four victims (131 males, 171 females) of the 1997 flood of the Red River returned surveys assessing their levels of preparation, resource losses, and psychopathology 12 to 16 months after the flood. It …

Predicting Flock Vigilance From Simple Passerine Interactions: Modelling With Cellular Automata, David B. Bahr, Marc Bekoff

Ethology Collection

Vigilance in flocks can be described and modelled as a plausible set of local interactions between neighbouring birds. Each bird in the modelled flock chooses to feed or to scan based solely on whether or not its neighbours are feeding or scanning. This simple model has the ability both to reproduce observations that have not been previously explained and to predict flock behaviours that might be confirmed with future field studies. Examples include simulations showing decreased vigilance with increased flock size (as observed in the field), greater time spent scanning when obstacles such as trees are present (as observed) and …

Asymmetry And Fighting Performance In The Shore Crab Carcinus Maenas, Lynne U. Sneddon, John P. Swaddle

Veterinary Science and Medicine Collection

Fluctuating asymmetries (left–right differences in symmetric traits) can be negatively related to fitness parameters in a number of biological systems. Hence, it has been suggested that symmetric individuals should outcompete asymmetric individuals during intraspecific agonistic encounters. However, there is a lack of experimental evidence for such a relationship. We investigated the relationship between trait asymmetry (both directional and fluctuating asymmetry) and the outcome of agonistic encounters among size-matched male shore crabs. Our findings indicate that cheliped (‘weapon claw’) directional asymmetry is not related to the outcome of fights, whereas fluctuating asymmetry in the fifth pereiopod, but not the second pereiopod, …

Anger And Alcohol Use: A Model Of Coping Styles, Alcohol Expectancies And The Experience And Expression Of Anger, Shauna Willard

Masters Theses & Specialist Projects

The researcher investigated the relationship between anger experience and expression, coping styles, and expectancies regarding the effects of alcohol in a young male population. Anger experience and expression was measured using the State-Trait Anger Expression Inventory, coping styles were assessed using the Coping Response Inventory, alcohol expectancies were determined using the Alcohol Effects Questionnaire-2, and alcohol use was measured using the Alcohol Use Inventory. The results indicated that young males who abuse alcohol utilize less effective coping styles, such as cognitive avoidance. Alcohol abusing males also believe alcohol will increase their power and aggression. A linear regression demonstrated that males …

The Relationship Between Homicidal Fantasies And Dangerousness, James C. Peterson

All-Inclusive List of Electronic Theses and Dissertations

Aggressive behavior is a serious problem in the United States and has been studied from a variety of perspectives. Psychologists in many different settings are frequently asked to assess the risk of future dangerous behavior by individuals. Due to their important role, research into the prediction of dangerousness has dramatically increased in the past ten years. However, to date, research has offered few reliable predictors that can be used in such assessments. This exploratory study was designed to examine whether homicidal fantasies can be used to reliably discriminate between violent and non-violent individuals. Undergraduate male students (N=l42) completed a questionnaire …

Modifications Of Nitric Oxide And Sexual Behavior In Prenatally Stressed Male Rats, Stephen D. Miller

Master's Theses

Normal male sexual differentiation is the culmination of perfectly timed, prenatal gonadal hormone release. Prenatal stress (PS) has a detrimental effect upon this process, obstructing the natural development of brain structures and sexual behavior. Prenatally-stressed male rats exhibit many physiological and neuroendocrinological differences when compared to control males. PS has a particularly harmful effect upon male sexual behavior, to which the neurotransmitter nitric oxide (NO) has been shown to be intimately involved. The present experiment examined whether PS reduces nNOS, the rate limiting enzyme of NO, in the medial preoptic area (rnPOA) of male rats, and whether administration of the …

Single Parents And Organizational Commitment, Absenteeism, And Internal Motivation: An Initial Investigation, Melissa D. Broughton

Masters Theses and Doctoral Dissertations

This study examined the relationship between group membership (by maritalstatus and sex) and the salience of the family role identities of caregiver and provider. It was expected that both the provider and caregiver roles would be salient for single parents. Results indicated that mothers identified with the caregiver role to a greater extent than fathers. However, no support was found for the idea that custodial single fathers identify with the caregiver role to the same extent as mothers. Results marginally supported the idea that custodial single mothers identify with the provider role as highly as fathers do, whereas married mothers …

Trait Anxiety As A Moderator Of Problem Structuring Effects On Solution Generation, Judith A. Wightman

Student Work

This study investigated the effects of problem structuring and anxiety on the quantity and quality of solutions generated for ill-structured, complex problems. Trait anxiety, the tendency to feel anxious across a wide variety of situations, has been shown to impair problem solving performance in certain conditions. Trait anxiety was examined as a possible moderator of the relationship between problem structuring and solution generation. Participants were 184 undergraduate psychology students. Participants completed a trait anxiety measure (State-Trait Anxiety Inventory; Spielberger, 1983) and generated solutions to an ill-structured problem, with varying levels of structuring (no objectives, one-objective-at-a-time, conflicting objectives). The quantity and …

Analysis Of The Caloric Expenditure Of Students In Middle School Physical Education Classes, Wendy Granum Frappier

Theses and Dissertations

According to the recent Surgeon General's Report guidelines, all Americans including children need to bum a minimum of 150 calories in daily physical activity or approximately 1,000 calories a week to meet minimum healthy activity standards. The purpose of the study was to assess the caloric expenditure of students in middle school physical education classes to determine if they were expending a sufficient amount of calories in physical education classes to meet the minimum healthy activity recommendations. More specifically, the study determined the differences in caloric expenditure and various physical activities, the relationship between heart rate and caloric expenditure, sex …

Take My Thesis…Please! The Art Of Stand-Up Comedy, Kyle J. Dukart

Theses and Dissertations

In my thesis, I explore the artistry of stand-up comedy primarily by concentrating on five aspects of the genre that one generally uses to discuss literature: theme, persona, language, narrative structure, and audience. My purpose is to critically analyze a mode of artistic expression that is rarely given serious academic consideration

To accomplish this purpose I researched various theories of comedy and then proceeded to listen to and read about dozens of stand-up comedians. Using my own and other's knowledge of comedy and literature, I then closely analyze parts of routines from ten of the comedians I studied, including Lenny …

Overcoming Response Bias Using Symbolic Representations Of Number By Chimpanzees (Pan Troglodytes), Sarah T. Boysen, Kimberly L. Mukobi, Gary G. Berntson

Sentience Collection

We previously reported that chimpanzees were unable to optimally select the smaller of two candy arrays in order to receive a larger reward. When Arabic numerals were substituted for the candy arrays, animals who had had prior training with numerical symbols showed an immediate and significant improvement in performance and were able to select reliably the smaller numeric representation in order to obtain a larger reward. Poor performance with candy arrays was interpreted as reflecting a response bias toward the intrinsic incentive and/or perceptual features of the larger array. In contrast, the Arabic numerals represent numerosity symbolically and appear to …

A Three-Choice Drug Discrimination Procedure Differentiates The Stimulus Effects Of D-Amphetamine And Mdma, Amy K. Goodwin

Masters Theses

(±)-3,4-Methylenedioxymethamphetamine (MDMA) produces effects in humans that are reportedly similar to those of CNS stimulants. However, drug discrimination studies in nonhumans have yielded inconsistent results regarding the similarities between MDMA and d-amphetamine. Sixteen male Sprague-Dawley rats were trained to discriminate d-amphetamine, MDMA, and saline in a three-lever drug discrimination procedure. In addition, differential outcomes were employed during drug discrimination training with eight of the rats but this did not appear to facilitate the acquisition of the discrimination. Cocaine (0.25-10.0 mg/kg) produced dose dependent increases in d-amphetamine-appropriate responding with complete substitution at the highest dose administered. LSD (0.02-0.16 mg/kg), produced dose …

Retention Of Academic Skills Over The Summer Months In Alternative And Traditional Calendar Schools, Christy Nofsinger

Masters Theses & Specialist Projects

Alternative calendar schools are increasingly popular alternatives to the traditional nine-month school year and a three-month summer vacation. One purported advantage of a shorter summer vacation is the greater retention of academic material because there is less time to "forget" what was learned. While alternative calendar schools appear to be increasing in number, little research has been conducted to actually measure academic differences in these schools. The purpose of this research was to systematically compare the retention of academic skills of students in traditional and alternative calendar schools over the summer months. Three county-wide school districts participated in this study. …

Local And Global Stereopsis In The Horse., B Timney, K Keil

Brain and Mind Institute Researchers' Publications

Although horses have laterally-placed eyes, there is substantial binocular overlap, allowing for the possibility that these animals have stereopsis. In the first experiment of the present study we measured local stereopsis by obtaining monocular and binocular depth thresholds for renal depth stimuli. On all measures, the horses' binocular performance was superior to their monocular. When depth thresholds were obtained, binocular thresholds were several times superior to those obtained monocularly, suggesting that the animals could use stereoscopic information when it was available. The binocular thresholds averaged about 15 min arc. In the second experiment we obtained evidence for the presence of …

The Dna Sequence From A Cloned 15 Kilobase Fragment Of The Chlamydomonas Acidophila Mitochondrial Genome And Rna Transcript Production In Response To Cadmium, Scott A. Hoffman

Theses and Dissertations

Chlamydomonas acidophila is a unicellular green alga of the order Chlamydomonadales. Our research efforts were allied along two lines: (1) Characterization of the C. acidophila mitochondrial genome (mtDNA) and (2) Elucidation of any molecular events responsible for C. acidophila's heavy metal tolerance. The mitochondrial genomes of the protists have been underrepresented in the sequence databases. Among the protists, the alga genera Chlamydomonas shows a reduced mtDNA content with a highly rearranged gene structure. It was decided to sequence C. acidophila's mtDNA to further elucidate the evolutionary paths among the Chlamydomonads and add to the protist sequence database. A 15 kb …

"Billy Yank" On The Northern Plains: The Lives Of Union Soldiers On The Minnesota-Dakota Frontier From The Great Sioux Uprising To 1866, Darrin F. Boehm

Theses and Dissertations

This thesis will tell the generally forgotten story of the Civil War era soldiers on the Minnesota-Dakota frontier who fought in the Great Sioux Uprising from 1862 to 1865. It will also compare the frontier soldiers’ campaign experience with the experiences of Bell Irvin Wiley’s Civil War ‘'Billy Yanks.”

This thesis covers enlistment procedures, food, clothing, shelter, discipline, disease, boredom, combat, the “galvanized” Yankees, the Dakota landscape, and the role of the cavalry. This story of the frontier soldiers’ expeditions against the Sioux on the northern plains is told using direct quotations from frontier soldiers’ diaries and manuscripts, along with …

The Effects Of Thought Suppression On Later Recall Of Valenced, Self-Referenced Adjectives, Danial S. Sturgill

Theses and Dissertations

This study examined the effects of thought suppression on later recall of valenced material. According to Wegner's (1994) theory of ironic mental processes, effortful attempts at thought suppression result in an increased accessibility of the to-be-suppressed thought under conditions of high cognitive load. Participants (N = 180) received an induced-sadness manipulation before being asked to concentrate on associations between visual images (either a white bear or an brown rabbit) and 28 adjectives (14 positively-valenced, 14 negatively-valenced). After a five minute period of suppressing thoughts of one of the visual images, participants were asked to remember as many of the 28 …
