The Rear-End Collision — Soma Or Psyché?, Hugh A. Clarke Sep 1977

The Rear-End Collision — Soma Or Psyché?, Hugh A. Clarke

Henry Ford Hospital Medical Journal

Rear-end collisions represent 25% of all vehicular accidents. On occasion, the patients become more disabled by the diagnosis of "whiplash" than by the injury. During the past three years, 100 patients were referred for neurological examination and disposition following rear-end collisions. Appropriate neurological testing, included the Minnesota Multiphasic Personality Inventory Test (MMPI). A minority of these patients required hospitalization. The incidence of disc rupture requiring surgical decompression was less than 1%. The psychological tests were of limited aid in helping the physician to treat this group of patients. The middle-aged patient without concomitant arthritic change, having secured conservative treatment in …


The Treatment Of Chronic Pain: Program Of The Community Hospital Rehabilitation Center For Pain, Karl L. Manders Sep 1977

The Treatment Of Chronic Pain: Program Of The Community Hospital Rehabilitation Center For Pain, Karl L. Manders

Henry Ford Hospital Medical Journal

After approximately three years' experience, the use of multiple modality treatment appears to be the most advantageous for individuals who have not responded satisfactorily to routine medical and surgical treatment. Alleviation of pain, discontinuance of narcotic medication, and return to both social and vocational activities has been accomplished in most patients of this center for the treatment of chronic pain.

Aboriginal Exploitation Of Marine Food Resources, Alan J. Osborn Jul 1977

Aboriginal Exploitation Of Marine Food Resources, Alan J. Osborn

Department of Anthropology: Theses and Student Research

Anthropological interest in human exploitation of resources has increased considerably during the last decade. Archaeological and ethnological literature concerning man's utilization of the world's oceans is relatively abundant and there are now several on-going anthropological research programs, e.g., Aleutian Islands, Pacific Northwest Coast, California, Hawaii, Australia, New Zealand, Peru, Ecuador, Chile, and Southern Africa which focus primarily on maritime adaptations. The purpose of this study is threefold: (1) to suggest that anthropological assumptions regarding marine food resources and their use are inadequate; (2) to examine marine ecosystems with respect to structure and dynamics, primary productivity, ecological efficiencies, distributional and quantitative …

Clinical Uses Of Biofeedback: A Review Of Recent Research, Richard M. Lee, Scott E. Baldwin, Julia A. Lee Jun 1977

Clinical Uses Of Biofeedback: A Review Of Recent Research, Richard M. Lee, Scott E. Baldwin, Julia A. Lee

Henry Ford Hospital Medical Journal

Biofeedback refers to a special type of operant conditioning (ie, a category of learning) in which subjects acquire control over physiological processes through the feedback of information. Its methodology is based upon principles of behavioral science developed in the laboratory through experimentation. It has been conclusively demonstrated that humans (and other animals) can learn to control such actions as EKG parameters, blood pressure, body temperature, EEG, individual motor units, and glandular secretions. Clinically, biofeedback has been applied to a wide variety of psycho-physiologic disorders in which a measurable response requires alteration. The best established applications are tension and migraine headaches, …


Forage Preferences Of Mule Deer In The Lodgepole Pine Ecosystem, Ashley National Forest, Utah, Joseph A. Deschamp May 1977

Forage Preferences Of Mule Deer In The Lodgepole Pine Ecosystem, Ashley National Forest, Utah, Joseph A. Deschamp

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

During the summer of 1976, five tame, trained mule deer (Odocoileus hemionus hemionus) were used to determine botanical composition and relative preference of mule deer diets on five habitat segments in the lodgepole pine (Pinus contorta) ecosystem of northeastern Utah. Diets were statistically analyzed according to estimated weight consumption per unit of time spent feeding on the different segments. Habitat segments sampled were: clearcut forest, dry and wet meadow, mature forest, and stagnated forest.

Diets differed between segments mainly because of differences in plant species available and their abundance. The diets in the non-forested segments averaged …


Influence Of Angler Motivations, Expectations, And Opinions On Fishery Management Practices In The United States, James E. Brogdon May 1977

Influence Of Angler Motivations, Expectations, And Opinions On Fishery Management Practices In The United States, James E. Brogdon

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

This report is concerned with the behavioral inputs into the decisions concerning fishery resource management. Topics discussed are motives, expectations, and opinions of fishermen concerning the fishing experience and present-day fishery management practices and regulations; how management agencies and sportsmen organizations have dealt with recreational fishing; the need for managers to utilize this behavioral information in forming management decisions; and where past people-wildlife research has been and where it must lead in the future. Material for this paper came from copies of published articles and library research.


A Field Study In The Use Of Dietary And Urinary Variables In Determining Osteoporosis In Elderly People, Jane Steger Osborn May 1977

A Field Study In The Use Of Dietary And Urinary Variables In Determining Osteoporosis In Elderly People, Jane Steger Osborn

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Three-day dietary records were analyzed for nutrient content and 24 hour urine samples were analyzed for calcium, phosphorous, total nitrogen, and free alpha-amino nitrogen for 210 elderly people. Dietaries and urine samples were collected twice, October and March at five month intervals, for each subject. Increases were found in both dietary intake and urinary components October to March. Based on a criteria of high dietary protein, low dietary calcium, high urinary nitrogen and low calcium, 23 subjects were selected as osteoporotic and and 25 were selected as non-osteoporotic. This method of prediction was not supported by radiological evaluations.

Subtle Teratogenic Effects Of Locoweed In Rats, Benjamin K. Nelson May 1977

Subtle Teratogenic Effects Of Locoweed In Rats, Benjamin K. Nelson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Locoweed, a well-known teratogenic plant affecting livestock, is prevalent in mountain regions of the Western United States. Two common species (Astragalus lentiginosus and A. wootoni), administered to pregnant rats, induced behavioral deviations in their offspring. Treated mothers consumed less feed and gained less wieght during gestation than controls when gavaged locoweed at the rate of 1 gram whole plant per day on days 7 through 17 of gestation. A. lentiginosus reduced pup weight at birth (13% less than controls) and this weight reduction (as much as 29% less than controls) continued at least four weeks. A. lentiginosus also …


Sex-Linked Mental Retardation Without Physical Stigmata (Martin-Bell Or Renpenning Type) : A Genetic And Psychometric Approach, Craig L. Hanis Apr 1977

Sex-Linked Mental Retardation Without Physical Stigmata (Martin-Bell Or Renpenning Type) : A Genetic And Psychometric Approach, Craig L. Hanis

Theses and Dissertations

Screening the Utah State Training School (a resident institution for the mentally retarded) for kindreds having at least two institutionalized sibs generated 54 sib groups. Of these, 20-male only sibships had histories compatible with sex-linked mental retardation without physical stigmata (Martin-Bell or Renpenning type). Affected males had no characteristic physical stigmata (an appreciable number did have speech problems and/or seizure disorders) and exhibited IQs ranging from 5 to 74 with a mean of 34.2. Obligate carrier females had a mean IQ score of 91.9 (range, 79 to 106), which is as would be predicted due to random X-inactivation. Carrier females …

Colorado Deer Hunting Experiences, Perry J. Brown, Jacob Hautaluoma, S. Morton Mcphail Mar 1977

Colorado Deer Hunting Experiences, Perry J. Brown, Jacob Hautaluoma, S. Morton Mcphail

Forest Management Faculty Publications

Those responsible for managing environmental resources, like big game, have often posed questions regarding how best to manage and allocate the resource to “provide benefits to people.” One approach to obtaining information for answering these questions is based on consumer behavior concepts and research.

Our consumer-oriented approach to deriving management information for environmental resources, particularly game and other recreational resources, rests on ideas conceptualized by Wagar (1966) and having their theoretical base in psychology’s expectancy-value theory (Lawler 1973). The general theoretical orientation we follow is described in Driver and Brown (1975). We also acknowledge a debt to the multiple satisfactions …


A Study Of Dietary Calcium And Phosphorus Intakes In Relation To Residual Ridge Resorption, Rita L. Sørensen Mar 1977

A Study Of Dietary Calcium And Phosphorus Intakes In Relation To Residual Ridge Resorption, Rita L. Sørensen

Loma Linda University Electronic Theses, Dissertations & Projects

Resorption of alveolar bone, a characteristic observed in periodontal disease, in the totally edentulous mouth and in generalized osteoporosis, is a common world-wide phenomenon in man. Calcium deficiency and calcium-phosphorus imbalance are implicated as plausible factors in all three instances.

A compilation of recent investigations strongly suggests that oral bone loss, whether in periodontal disease or in the residual ridges, is an early manifestation of osteoporosis; and that osteoporosis, in general, is associated with disturbed calcium homeostasis.

This study, patterned after that of Wical and Swoope, was conducted on 55 subjects who had been totally edentulous for at least three …


Social Communication In Canids: Evidence For The Evolution Of A Stereotyped Mammalian Display, Marc Bekoff Jan 1977

Social Communication In Canids: Evidence For The Evolution Of A Stereotyped Mammalian Display, Marc Bekoff

Ethology Collection

The variability in the duration and form of the canid play bow was studied in infant coyotes, wolves, wolf-dog hybrids, beagles, and adult free-ranging dogs. Both duration and form showed marked stereotypy. It appears that the role of this context-specific social signal in the communication of play intention has been fostered by selection for "morphological" stereotypy.

Visual Detection Of Cryptic Prey By Blue Jays (Cyanocitta Cristata), Alexandra T. Pietrewicz, Alan Kamil Jan 1977

Visual Detection Of Cryptic Prey By Blue Jays (Cyanocitta Cristata), Alexandra T. Pietrewicz, Alan Kamil

Avian Cognition Papers

Blue jays learned to respond differentially to the presence or absence of Catocala moths in slides. This detection of the moths by the jays was affected by the background upon which the moth was placed and its body orientation, thus providing an objective measure of crypticity. These procedures are useful for the study of visual detection of prey.


The Effects Of Forebrain Ablations On Some Behaviors In Xenopus Laevis, Lawrence Paul Kunstadt Jan 1977

The Effects Of Forebrain Ablations On Some Behaviors In Xenopus Laevis, Lawrence Paul Kunstadt

Dissertations, Theses, and Capstone Projects

In order to further elucidate the hypothesis that the telencephalon of ectothermic vertebrates functions primarily as a non-specific arousal mechanism, facilitating lower brain areas, (the Arousal Hypothesis) the South African clawed frog, Xenoous laevis, was studied in four behavioral situations before and after telencephalon ablation, olfactory bulb ablation or sham surgery. Particular attention was paid to measurements of the temporal aspects of the behaviors studied.

The behaviors studied were:

1. Habituation to an acoustic-vibratory stimulus

2. The optomotor response

3. Escape from shallow water

4. Feeding behavior

In the habituation experiment no changes were found in the number of …
