The Effect On Feeding And Wheel Running Behaviours Of Housing Rats In Pairs, Roison M. O'Connor

Theses and Dissertations (Comprehensive)

The effects on feeding of moving animals from individual- to pair-housing were explored in the present three experiments. Wheel access is known to result in a temporary suppression of feeding. The move to pair-housing was compared with the effect of wheel access. In Experiment l, a group of rats was moved from individual to pair-housing (IP group) and compared to a group of individually-housed rats (IND group) and a group of chronically pair-housed rats (PAIR group). The animals in the IP group showed a temporary (three days) suppression in feeding (initially 23%). When half of the IND and PAIR group …

An Examination Of Environmental Sensitivity Among Supporters Of An Outdoor Recreation Area, Rodney James Blackman

Dissertations and Theses @ UNI

The environment as an issue has been prominently before the public for over three decades. Yet the question of how much people know about the natural environment and how committed they are to the environment has seldom been considered in research literature. Research of this nature is needed because without it individuals interested in the preservation and conservation of the environment cannot be sure how their efforts to increase people's environmental sensitivity should be applied. The purpose of this study was to examine the level and extent of environmental sensitivity among supporters of an outdoor recreation area/facility in northeast Iowa. …

Competitive Orientations And Motives Of Adult Sport And Exercise Participants, Diane L. Gill, Lavon Williams, Deborah A. Dowd, Christina M. Beaudoin, Jeffrey J. Martin

Kinesiology, Health and Sport Studies

Participants in four different adult sport and exercise programs (running club, exercise classes, cardiac rehabilitation program, senior games) completed measures of competitive orientation and participation motivation. Our samples were older and more diverse than samples of previous research, and their competitive orientations and motives were similarly diverse. Multivariate analyses revealed gender and sample differences. Males were higher than females on competitiveness and win orientation, and runners were less win-oriented than other groups, but overall, all groups were similar to previous college-age samples in competitive orientation. Groups varied on specific motives, with females rating fitness, flexibility, affiliation, and appearance higher than …

Genomics: Past & Future

AT THE END OF THE ROAD in Little Cottonwood Canyon, near Salt Lake City, Alta is a place of near-mythic renown among skiers. In time it may well assume similar status among molecular geneticists. In December 1984, a conference there, co-sponsored by the U.S. Department of Energy, pondered a single question: Does modern DNA research offer a way of detecting tiny genetic mutations—and, in particular, of observing any increase in the mutation rate among the survivors of the Hiroshima and Nagasaki bombings and their descendants? In short the answer was, Not yet. But in an atmosphere of rare intellectual fertility, …

Immunolesions Using Site Specific Injections Of 192-Lgg Saporin Into The Basal Forebrain Fail To Affect Radial Arm Maze Performance In The Male Rat, Lesley J. Hickman '96

Honors Projects

In this study I investigated the effects of 192-lgG saporin injections into the medial septal area.(MSA) and nucleus basalis magnocel/ularis (NBM) on radial arm maze performance in the male rat. The results of the present study reveal that combined injections of 192-lgG saporin into the basal forebrain failed to disrupt RAM performance when compared to vehicle-injected controls. In addition, intraperitoneal injections using a muscarinic receptor blocker, scopolamine, failed to reveal a compensatory response of the cholinergic basal forebrain that may have explained the lack of behavioral effects of 192IgG saporin. Consequently, the results of this study suggest that a selective …

Social Assemblages And Mating Relationships In Prairie Dogs: A Dna Fingerprint Analysis, Steven E. Travis, Con Slobodchikoff, Paul Kefan

Reproductive Behavior Collection

Mating system characterizations have been hindered by difficulties in accurately assigning parentage to offspring. We investigated the relationship between social assemblages and mating relationships in a territorial harem polygynous mammal, the Gunnison's prairie dog, using a combination of behavioral and molecular analyses. We demonstrate multiple paternity and an extraordinarily high incidence of extraterritorial fertilizations (i.e., 61% of all progeny), in combination with the existence of female kin groups. On this basis, we conclude that social assemblages alone provide a poor description of the Gunnison's prairie dog mating system, and suggest several potential reasons for the maintenance of territoriality in this …

Physiological Responses To Various Durations And Intensities Of Warmup, Susan J. Hanson

Student Work

Warmup has been a general practice for most athletes to engage in prior to a practice or competitive race. However, there has been little scientific evidence, specifically for the endurance athlete concerning the appropriate duration, intensity, or a combination of duration and intensity needed to enhance performance. Therefore, the purpose of this study was to determine how different combinations of durations and intensities of warmup affect heart rate (HR), lactic acid· (LA), minute ventilation (VE), respiratory exchange ratio (R) and rating of perceived exertion (RPE) during a 5 minute treadmill run at 80% VO2 max. Subjects included four male and …

Bad Ethics, Good Ethics And The Genetic Engineering Of Animals In Agriculture, Bernard Rollin

Genetics Collection

Genetic engineers have been remiss in addressing ethical and social issues emerging from this powerful new technology, a technology whose implications for agriculture are profound. As a consequence of this failure, society has been uneasy about genetic engineering of animals and has had difficulty distinguishing between genuine and spurious ethical issues the technology occasions. Many of the most prominent concerns do not require a serious response. On the other hand, concerns about a variety of possible risks arising from genetic engineering of animals require careful consideration and dialogue with the public. Such concerns are an admixture of ethics and prudence. …

A Rodent For Your Thoughts: The Animal Model Strategy In Psychology, Kenneth J. Shapiro

Experimentation Collection

In this second of three essays, I describe how the early modern psychologists adopted the strategy of further transforming rats and other species into models of human thought, feeling, and behavior, and, particularly, of disorders of these - in effect taking "a rodent for your thoughts." In the third essay I will provide a critique and empirically-based evaluation of animal model research. Here I indicate what the model strategy in the biomedical sciences, properly understand, is intended to achieve and how, by contrast, particular models are presented to the public and funding agencies. Finally, I describe how they are utilized …

The Ingrown World Of Animal Model Research In Psychology, Kenneth J. Shapiro

Experimentation Collection

In the previous essay, I described the proper function of models in science as heuristic, as a way of generating hypotheses about the actual object of study. Turning to animal models in psychology, I offered a general characterization of that enterprise using sham feeding, an animal model of the eating disorder called bulimia, as an example. In this final of three essays, I offer an evaluation of this animal model strategy that largely employs the tools of social science. I close with a recommendation and a prediction.

Quantity-Based Interference And Symbolic Representations In Chimpanzees (Pan Troglodytes), S. T. Boysen, G. G. Berntson, M. B. Hannan, J. T. Cacioppo

Sentience Collection

Five chimpanzees with training in counting and numerical skills selected between 2 arrays of different amounts of candy or 2 Arabic numerals. A reversed reinforcement contingency was in effect, in which the selected array was removed and the subject received the nonselected candies (or the number of candies represented by the nonselected Arabic numeral). Animals were unable to maximize reward by selecting the smaller array when candies were used as array elements. When Arabic numerals were substituted for the candy arrays, all animals showed an immediate shift to a more optimal response strategy of selecting the smaller numeral, thereby receiving …

Mechanisms Of American English Vowel Production In A Grey Parrot (Psittacus Erithacus), Denice K. Warren, Dianne K. Patterson, Irene M. Pepperberg

Sentience Collection

Parrots are known for their capacity to reproduce the sounds of human speech, but few studies have investigated their mechanisms for producing such vocalizations. Using three methods of noninvasive video imaging (Super VHS video, infrared, X-ray radiography), we examined correlations between several elements of a Grey Parrot's (Psittacus erithacus) vocal-tract configuration and the bird's production of two vowels, /i/ ("eat") and /a/ ("rock"). This parrot uses mechanisms that both resemble and differ from those used by: (a) humans to produce English speech; and (b) some avian species to produce conspecific vocalizations. This Grey Parrot, for example, uses its vocal apparatus …

Gender Differences In Attitudes Toward Animal Research, Jennifer J. Eldridge, John P. Gluck

Experimentation Collection

Although gender differences in attitudes toward animal research have been reported in the literature for some time, exploration into the nature of these differences has received less attention. This article examines gender differences in responses to a survey of attitudes toward the use of animals in research. The survey was completed by college students and consisted of items intended to tap different issues related to the animal research debate. Results indicated that women were more likely than men to support tenets of the animal protection movement. Likewise, women were more likely than men to favor increased restrictions on animal use …

Semantic And Schematic Similarities Between Database Objects: A Context-Based Approach, Vipul Kashyap, Amit P. Sheth

Kno.e.sis Publications

In a multidatabase system, schematic conflicts between two objects are usually of interest only when the objects have some semantic similarity. We use the concept of semantic proximity, which is essentially an abstraction/mapping between the domains of the two objects associated with the context of comparison. An explicit though partial context representation is proposed and the specificity relationship between contexts is defined. The contexts are organized as a meet semi-lattice and associated operations like the greatest lower bound are defined. The context of comparison and the type of abstractions used to relate the two objects form the basis of a …
