Spatial Memory In Seed-Caching Corvids, Alan Kamil, Russell P. Balda Jan 1990

Spatial Memory In Seed-Caching Corvids, Alan Kamil, Russell P. Balda

Papers in Behavior in Biological Sciences

Our purpose in this article is to review the results of our studies of the mechanisms underlying cache recovery by members of the crow, jay, and nutcracker family. In this research program, we have combined psychological and ecological approaches to the study of memory, and the results demonstrate the utility of this interdisciplinary strategy. Unlike most psychological research on learning and memory, this research program originated in the study of how a particular species solves a particular ecological problem. It serves as an example of how natural history and ecology can provide the starting point for a research program that …


Evidence For Common Coding Of Temporal And Nontemporal Information In Pigeons, Stephen Bridson Jan 1990

Evidence For Common Coding Of Temporal And Nontemporal Information In Pigeons, Stephen Bridson

Theses and Dissertations (Comprehensive)

Two experiments found evidence that pigeons commonly code temporal and visual samples that are associated with the same comparisons in many-to-one matching. In Experiment 1, pigeons were trained to match temporal (2-sec and 8-sec keylight durations) and color (red and green) samples to line tilt comparisons (vertical and horizontal). Similar rates of forgetting were found for all samples. Furthermore, retention of sample information appeared more similar for samples which shared common comparisons than those that did not. In Experiment 2, pigeons learned new comparison (circle and triangle) associations with either temporal or visual samples from Experiment 1. When tested on …


Anaerobic Power Of A College Basketball Team Throughout One Season, Mark Frederick Ackerman Jan 1990

Anaerobic Power Of A College Basketball Team Throughout One Season, Mark Frederick Ackerman

Dissertations and Theses @ UNI

The purpose of this study was to describe the changes in anaerobic power of a NCAA Division I men's college basketball team over the course of a season using the Wingate Anaerobic Test.

Administered on a bicycle ergometer, the Wingate Anaerobic Test was given to 15 members of the University of Northern Iowa men's basketball team four different times over the course of a season. During the season the team participated in no specific conditioning program for anaerobic power and relied on regular practices and games for all conditioning.

The Wingate Anaerobic Test measured maximal anaerobic power, anaerobic capacity, and …


Nutritive And Nonnutritive Sucking And The Temporal Organization Of The Suckling Behavior Of Domestic Piglets, Jeffrey Rushen, David Fraser Dec 1989

Nutritive And Nonnutritive Sucking And The Temporal Organization Of The Suckling Behavior Of Domestic Piglets, Jeffrey Rushen, David Fraser

Feeding Behavior Collection

Detailed video recordings of the suckling behavior of one piglet from each of four litters were analyzed to determine how the components of piglet suckling behavior are organized in relation to the time of milk ejection and the temporal pattern of grunting by the sow. Early in the suckling episode, most piglets massaged the udder with their snouts, and then changed gradually to sucking the teats with slow mouth movements (1-2/sec). The piglets then had a distinct phase of sucking with rapid mouth movements (4-5/sec) which began suddenly and lasted about 5 to 15 sec. The weight gains of piglets …


Achilles Tendon Replacement By A Collagen Fiber Prosthesis: Morphological Evaluation Of Neotendon Formation., Arthur J. Wasserman, Y. Pedro Kato, David Christiansen, Michael G. Dunn, Frederick H. Silver Nov 1989

Achilles Tendon Replacement By A Collagen Fiber Prosthesis: Morphological Evaluation Of Neotendon Formation., Arthur J. Wasserman, Y. Pedro Kato, David Christiansen, Michael G. Dunn, Frederick H. Silver

Scanning Microscopy

Reconstituted type I collagen was processed into fibers which were subsequently severely dehydrated and cyanamide cross-linked. Fibers prepared by this method were stronger and more resistant to degradation than uncrosslinked fibers. When used as a tendon replacement prosthesis, morphological events occurred which were observed by light, scanning, transmission electron microscopy and electron histochemistry.

Resorption was the initial host response to the prosthesis and involved gradual biodegradation. Formation of a host-replacement tendon was the second response. Increased collagen fibril diameters and a transition in the proteoglycan/collagen fibril interactions occurred in the newly developing connective tissue between 3 and 10 weeks post-implantation. …

Living With A Hereditary Form Of Cancer: Experiences And Needs Of Men 2 Patients And Their Families, Marc P. H. D. Cleiren, Wil Oskam, Cornelis J. M. Lips Sep 1989

Living With A Hereditary Form Of Cancer: Experiences And Needs Of Men 2 Patients And Their Families, Marc P. H. D. Cleiren, Wil Oskam, Cornelis J. M. Lips

Henry Ford Hospital Medical Journal

Unlike the purely medical research done in multiple endocrine neoplasia type 2 (MEN 2) families, little work has been done on the psychosocial aspects of the disease. To assess the severely stressful influences and the consequences of that stress on the family network, a small-scale survey was carried out during a national meeting. The goal of the study was to obtain more information about the experiences and needs of MEN 2 patients and their relatives. Of the 59 respondents, 85% were satisfied with the medical information provided, 81% were satisfied with the medical knowledge of the specialist, but only 12% …


Quality Of Life After Bilateral Adrenalectomy In Men 2, M. Telenius-Berg, M. A. Ponder, B. Berg, B. A. J. Ponder, S. Werner Sep 1989

Quality Of Life After Bilateral Adrenalectomy In Men 2, M. Telenius-Berg, M. A. Ponder, B. Berg, B. A. J. Ponder, S. Werner

Henry Ford Hospital Medical Journal

Pheochromocytoma is a major cause of morbidity and mortality in the multiple endocrine neoplasia type 2 (MEN 2) syndrome. For the physician, surgical treatment seems well justified even though bilateral adrenalectomy will induce iatrogenically complete loss of adrenocortical function. For the patient this treatment may be a cause of medical problems as well as worry. We have evaluated quality of life after bilateral adrenalectomy in 27 MEN 2 patients through a combined oral and written approach. Mortality was low (one of 27), as was serious morbidity. Most patients had adapted well to the postadrenalectomy state. However, fatigue, worry, and noncompliance …

Simultaneous Determination Of 3-Methoxy-4-Hydroxyphenyl-Glycol, Homovanillic Acid, And 5-Hydroxyindoleacetic Acid In Plasma By High Performance Liquid Chromatography, Yung-Te Tseng

Chemistry & Biochemistry Theses & Dissertations

A rapid, reliable, and sensitive method for simultaneous determination of 3-methoxy-4-hydroxyphenylglycol (MHPG), Homovanillic acid (HVA), and 5-hydroxyindoleacetic acid (5- HIAA) in plasma is described. The method is based on high performance liquid chromatography with electrochemical detection. Samples were filtered with Amicon Centrifree micropartition systems and extracted with organic solvent before chromatography. Chromatographic separation of sample components was achieved isocratically in a C18 reverse-phase column. Quantitation was performed by measuring the peak height ratios of the sample components to an internal standard. Analytical recoveries ranged from 50.78 (SD 4.2%) to 67.94 (SD 3.28). Within-run coefficient of variations (CVs) ranged from 3.78 …


The Nebraska Natural Heritage Program: Two Year Progress Report, Mary Clausen, Mike Fritz, Gerry Steinauer Jun 1989

The Nebraska Natural Heritage Program: Two Year Progress Report, Mary Clausen, Mike Fritz, Gerry Steinauer

Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts

Since European settlement, human activities have totally eliminated the natural vegetation from approximately 50 percent of Nebraska’s landscape, and of that remaining most has been heavily impacted. As a result, numerous plants and animals have been extirpated from the state and many others are threatened.

The destruction of Nebraska’s natural diversity resulted in both public and private conservation groups recognizing the need for a centralized and accessible biological database for the state’s rare species and natural community types. Toward this end, the Nebraska Natural Heritage Program (NENHP) was established in August, 1987 through a cooperative effort between The Nature Conservancy …


Symbolic Interactionist And Neurophysiological Models Of Action Towards An Integration, David Spencer Fearon May 1989

Symbolic Interactionist And Neurophysiological Models Of Action Towards An Integration, David Spencer Fearon

Senior Scholar Papers

This research proposal introduces an integrated study of action and human conduct from the perspectives of symbolic interaction and neurophysiology. Because of their traditionally disparate subject matter, the fields of sociological social psychology and the neurosciences seldom meet; however, I have found significant common ground to justify an integrated approach to the study of action. Symbolic interactionists study human group life and conduct in society. The neurosciences deal with the physiology of the central nervous system, its structure and functions in behavior, its chemical composition, and electrochemical activity, and the effects damage has on behavior. Both fields analyze the same …

Using Computer Imaging To Assess Visual Impacts Of Forest Insect And Disease Pests, Daniel Rabin May 1989

Using Computer Imaging To Assess Visual Impacts Of Forest Insect And Disease Pests, Daniel Rabin

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Forest insect and disease pests alter the appearance of trees, thereby impacting visual resources. Because of the complexity of most forest landscapes, the degree of visual impact of pest-infested forest stands is difficult to quantify.

This paper describes a method of measuring visual impacts of pest-infested forest stands. Photographs of healthy Ponderosa pine trees were entered into a computer video-image-processing system. Using this system, images of trees were altered to simulate different degrees of infestation by limb rust, a forest pathogen.

The altered and unaltered images were shown to groups of observers who rated the scenes in terms of "scenic …


A Longitudinal Study Of Dietary Intake And Influence Of Iron Status On Infants' And Toddlers' Mental And Motor Development, Steven Matley Wood May 1989

A Longitudinal Study Of Dietary Intake And Influence Of Iron Status On Infants' And Toddlers' Mental And Motor Development, Steven Matley Wood

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Thirty-two non-anemic children were assessed clinically, biochemically and anthropometrically at six months, one year and two years of age to investigate the relationship of iron status to mental and motor development. Using dietary history and dietary record instruments, dietary iron was estimated and compared to the National Food Consumption Survey (1985) and the Recommended Dietary Allowances (RDA) for corresponding age groups. The Bayley Scales of Infant Development (which assess mental and motor development) and the Caldwell Home Inventory (which evaluates the environmental stimuli) were performed and correlated with blood iron parameters, anthropometric measurements and dietary nutrient intakes.

Nutrient intakes of …


In Vitro Identification Of The Effect Of Serotonin On Lymphocyte Dna Synthesis And Natural Killer Cell Activity, Kim Kartchener Kane May 1989

In Vitro Identification Of The Effect Of Serotonin On Lymphocyte Dna Synthesis And Natural Killer Cell Activity, Kim Kartchener Kane

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this study was to identify the effects of the neurotransmitter, serotonin (SE), on the immune function of peripheral blood mononuclear cells (PBMC) of normal, healthy subjects. This was done as a preliminary investigation to studies on the association of SE with immune changes in autistic subjects.

The PBMC isolated from normal male subjects were treated with various concentrations of SE for 48 hrs. Their incubation in SE at a concentration of 10-3 M induced about a 35% decrease in DNA synthesis. However, incubation of the cells in lower concentrations (10-4 to 10-10) of …

Specificity Of The Cardiac Response To Conspecific Vocalizations In Chimpanzees, Gary G. Berntson, Sarah T. Boysen Apr 1989

Specificity Of The Cardiac Response To Conspecific Vocalizations In Chimpanzees, Gary G. Berntson, Sarah T. Boysen

Sentience Collection

Heart rate measures were used to examine the functional response of young chimpanzees and orangutans to acoustic stimuli, including white noise and chimpanzee vocalizations (threat, stress, and alarm). The initial response of the animals to all stimuli was characterized by a prominent cardiac deceleration and an increase in heart period variability. The deceleratory responses persisted with repeated presentations of the noise, stress, and alarm stimuli. In contrast, the response of chimpanzees to the conspecific threat stimulus reverted over trials to a notable cardiac acceleration. This acceleratory response was not attributable to potential patterns of evoked somatic responses. The features of …


Numerical Competence In A Chimpanzee (Pan Troglodytes), Sarah T. Boysen, Gary G. Berntson Mar 1989

Numerical Competence In A Chimpanzee (Pan Troglodytes), Sarah T. Boysen, Gary G. Berntson

Sentience Collection

A chimpanzee (Pan troglodytes), trained to count foods and objects by using Arabic numbers, demonstrated the ability to sum arrays of 0-4 food items placed in 2 of 3 possible sites. To address representational use of numbers, we next baited sites with Arabic numbers as stimuli. In both cases performance was significantly above chance from the first sessions, which suggests that without explicit training in combining arrays, the animal was able to select the correct arithmetic sum for arrays of foods or Arabic numbers under novel test conditions. These findings demonstrate that counting strategies and the representational use of numbers …


Non-Breeder Asymmetry In Florida Scrub Jays, Jonathan P. Balcombe Mar 1989

Non-Breeder Asymmetry In Florida Scrub Jays, Jonathan P. Balcombe

Ethology Collection

The data of Woolfenden and Fitzpatrick (1984) show a statistically significant asymmetry in the sex ratio of non-breeders when one of the breeders is not the non-breeder's parent. 1 propose that the asymmetry is attributable to a combination of two factors acting on non-breeders: the value of inheriting a territory, and incest avoidance. Although natal territories are only occasionally inherited by non-breeders, and then apparently only by males, the rate of inheritance is significantly higher for parent/step-parent breeders (n = 6) than when both breeders are the non-breeder's parents (n = 1). An alternative hypothesis, that step-parents determine the non-breeder …

Effects Of Age On Motor Preparation And Restructuring, Paul Amrhein, Noreen Goggin, George Stelmach

Department of Psychology Faculty Scholarship and Creative Works

Age-related decrements in motor plan restructuring were investigated. In this experiment, older and younger adults performed a discrete aiming task that involved responses that were precued and responses that were modified at the time of an imperative signal. On 75% of the trials, the precue specified the response-stimulus (valid trials) with respect to the movement parameters of the arm (left or right) and direction (toward or away). On the remaining 25% of the trials, the response-stimulus was different from the precue (invalid trials) in that the subject was required to modify a planned movement by changing the arm to be …

Conspecific Recognition In The Chimpanzee (Pan Troglodytes): Cardiac Responses To Significant Others, Sarah T. Boysen, Gary G. Berntson Jan 1989

Conspecific Recognition In The Chimpanzee (Pan Troglodytes): Cardiac Responses To Significant Others, Sarah T. Boysen, Gary G. Berntson

Sentience Collection

The ability of a chimpanzee (Pan troglodytes) to recognize photographs of conspecifics was evaluated with heart-rate measures. Heart rate was recorded before, during, and after viewing photographs of an aggressive chimpanzee, a friendly companion animal, and an unfamiliar chimpanzee. The subject displayed a differential pattern of heart-rate response to the stimulus animals, without prior experience with the photographs. Responses to the aggressive animal were acceleratory, which suggests a defensive response. Respiratory sinus arrhythmia suggested that this response was associated with sympathetic activation. In contrast, responses to the familiar animal were minimal, whereas cardiac deceleration was observed in response to the …


Perceptions Of The Texas State And Federal Closures Among Inshore Shrimpers In Galveston Bay, Texas And Calcasieu Lake, Louisiana, Nina H. Garfield Jan 1989

Perceptions Of The Texas State And Federal Closures Among Inshore Shrimpers In Galveston Bay, Texas And Calcasieu Lake, Louisiana, Nina H. Garfield

Marine Affairs Theses and Major Papers

The inshore shrimp fisheries along the coast of the Gulf of Mexico represent a significant portion of the total shrimp harvest in the Gulf. The shrimp harvest is allocated to the offshore and inshore fisheries through the use of season closures. In 1981, the Gulf of Mexico Regional Fisheries Management Council began implementing a policy known as the Texas Closure; a seasonal closure of the waters of the Federal Conservation Zone concurrent with the traditional season closure of the state waters of Texas. One impact of the Texas Closure on the offshore fishery has been fleet displacement from Texas to …
