The Potential Role Of Local Ethical Committees In The Moderation Of Experiments On Animals In Britain, D. P. Britt

Experimentation Collection

Scientists working with laboratory animals in Britain are made aware forcibly that a serious ethical dilemma surrounds the use of animals in experiments. Certain vociferous sections of the community press the issue on the attention of the general public and media sources tend to propagate views expressed by the most extreme parties, while neglecting coverage of mature, rational opinion. It is, perhaps no bad thing for the scientific community to be frequently reminded to take a responsible attitude to the use of animals but recent overt, even illegal, activity on the part of extremist animal protectionist groups has encouraged a …

Environmental Psychology And Great Ape Reproduction, Terry L. Maple

Zoos and Aquariums Collection

At the 1980 Great Ape Infertility Workshop, we concluded that "physical and social environments must be improved if not optimized if great apes are to reproduce satisfactorily ... " In 1982, the trend toward improvement continues and there are some promising signs that reproduction has been enhanced as predicted. The problem of designing and evaluating captive environments which will facilitate interaction, reproduction, appropriate parenting, and socialization is well within the scope of Environmental Psychology. I intend to illustrate the promise of this applied research field in the remarks that follow.

Review Of Literature On Use Of T-61 As An Euthanasic Agent, Laura Dalia Barocio

Veterinary Science and Medicine Collection

The tools of evaluating the degree of distress in animals being killed include electroencephalography (EEG), electrocardiography (ECG), and measurement of blood pressure and respiration. Sound clinical and behavioral observations should also not be abandoned in the evaIuation process.

There are many methods which may be employed to reach the same end results, but the ideal method should satisfy several criteria: 1. It should be painless; 2. It should cause unconsciousness instantaneously and death within minutes; 3. It should not cause undue anxiety, alarm, fear, panic, behavior, struggling, vocalization, muscle spasms or clinical signs of automatic activation (e.g., convulsions) before unconsciousness; …

Prostaglandin F2a Induced Nest Building Behavior In The Non-Pregnant Sow, And Some Welfare Considerations, Judith K. Blackshaw

Agribusiness Collection

Nest building behavior, induced with intramuscular injections of prostaglandin F2_a (PGF2_a), was studied in non-pregnant sows. Acute effects, which included salivation, scratching, vomiting, defaecation and ataxia, were also recorded. Sows (Large White x Landrace) were housed in two different environments; six sows in bare pens and six sows in pens provided with bedding material. In all cases except one (bare pen) nest building sequences of differing intensities were recorded. Welfare suggestions include questioning the justification of using a drug (PGF2_a) in pig husbandry, which has unpleasant acute effects, and the suggestion that the provision of …

Effects Of Moose, Alces Alces, On Aquatic Vegetation In Sibley Provincial Park, Ontario, D. Fraser, H. Hristienko

Feeding Behavior Collection

The effect of Moose (AIces aIces) on aquatic vegetation was studied in Sibley Provincial Park, Ontario. Two small exclosures were built in preferred feeding lakes to protect vegetation from Moose. Both exclosures developed a dense growth of plants. In one, species palatable to Moose were much more abundant than in unprotected areas. The other lake supported very little vegetation outside the exclosure. Aquatic vegetation in a large preferred lake underwent a series of changes from the 1960's to 1980. Nuphar variegatum and Potamogeton filiformis largely disappeared, leaving the lake sparsely vegetated in some years and dominated by annuals in others. …

Heg83-181 Managing Conflict Successfully, Herbert G. Lingren

University of Nebraska-Lincoln Extension: Historical Materials

This publication describes the differences between conflict and disagreement, and provides procedures for resolving them successfully.

How do you typically respond when you seriously disagree with someone? Do you...

1. get mad inside but keep quiet and give the other the "silent" treatment?

2. withdraw to a safe distance because you don't like to argue?

3. get angry, criticize, call names, use sarcasm or some other aggressive behavior?

4. give in; say "I guess you are right" with a big sigh, be submissive in order to avoid conflict.

5. deny or pretend that "everything is okay"--no conflict exists.

These are …

Dynamic Effects Of Food Magnitude On Interim-Terminal Interaction, Alliston K. Reid, Robert H.I. Dale

Scholarship and Professional Work - LAS

We tested the assumption of a facilitatory relation between periodic food presentation and schedule-induced drinking by examination of (a) elicited drinking, (b) drinking in anticipation of food delivery, and (c) possible indirect effects of food delivery on drinking. We exposed rats to a fixed-time 60-second schedule in which interfood intervals ended in either one or four food pellets with equal probability. In Phases 1 and 3, a stimulus signaled the magnitude of upcoming food presentation. In Phase 2, the stimulus was eliminated. Changes in drinking and "head-in-feeder" distributions within interfood intervals demonstrated that head-in-feeder was controlled directly by food presentation, …

The Foraging Behavior Of Lacewing Larvae On Vertical Rods, Alan B. Bond

Alan Bond Publications

The foraging behavior of lacewing larvae (Chrysopa carnea Stephens, Chrysopidae, Neuroptera) on vertical lucite rods was observed under a variety of experimental conditions to investigate the decision processes responsible for the distribution of foraging effort. Food deprivation increased the duration of searching on all parts of the rod, whereas contact with prey at the rod tip induced only a local enhancement of searching activity. Searching at the rod tip did not decline with repeated trials on the same rod, but the duration of searching on the rest of the rod was reduced, evidently reflecting recognition and avoidance of previously-searched …

The Relationship Between Whole Brain Catecholamine Depletion In Carassius Auratus And The Exposure To Inescapable Shock In A Learned Helplessness Paradigm, Roderick J. Misunis

Masters Theses

Learned helplessness is a psychological concept that describes the subsequent escape-avoidance behavior of experimental subjects who are exposed to uncontrollable stressors. Subjects after treatment are unable to respond in situations where escape is possible. Two major theorists, Seligman and Weiss, have proposed explanations concerning the phenomena. Seligman feels that the subject is unable to respond due to the fact that the exposure to an uncontrollable stressor has caused him to learn to be "helpless". Weiss feels that the inability to respond can best be described by alterations in the subject's brain neurochemistry, specifically the neurotransmitter norepinephrine. This paper is an …

Linguistic Competence, John Tienson

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

The notion of linguistic competence as a cognitive system that produces knowledge not antecedently present in the mind of the subject, e.g., knowledge of grammatical relations in response to certain stimuli is an important contribution to philosophical understanding of linguistics, and of cognitive psychology in general. This notion has not been as well received as it should have been, in part because of certain false things that have been said about it. In particular, it has been said that a grammar of a language, conceived as a theory of linguistic competence, is an idealization, and that speakers know the …

Optimal Foraging Theory And The Psychology Of Learning, Alan Kamil

Avian Cognition Papers

The development of optimization theory has made important contributions to the study of animal behavior. But the optimization approach needs to be integrated with other methods of ethology and psychology. For example, the ability to learn is an important component of efficient foraging behavior in many species, and the psychology of animal learning could contribute substantially to testing and extending the predictions of optimal foraging theory.

Visual Search And Selection Of Natural Stimuli In The Pigeon: The Attention Threshold Hypothesis, Alan B. Bond

Papers in Behavior in Biological Sciences

During visual search for samples of varying proportions of familiar, natural food grains displayed against a complex gravel background, pigeons exhibited “matching selection,” a tendency to overselect the more common grain. The matching selection effect was decreased at low levels of stimulus/background contrast and reversed when the grains were highly conspicuous. The results were consistent with the hypothesis that stimulus detectability should be enhanced by recent experience with a particular grain type, but they showed no convincing indications of a corresponding effect on the response criterion. An explanatory model, termed the attention threshold hypothesis, argues that the mean latency of …

Habitat Selection Related To Resource Availability Among Cavity-Nesting Birds, Timothy Brush

School of Integrative Biological & Chemical Sciences (Formerly Dept. of Biology)

Variation in snag species and abundance appeared to explain most of the habitat selection patterns observed in five cavity-nesting riparian species over a three-year period. All species except Ash-throated Flycatchers were most common in areas with cottonwood or willow snags, which have relatively soft wood and are preferred nest sites. Classification of habitats on the basis of nest-site characteristics was useful and should be considered in other habitat selection studies.

Aquatic Feeding By Moose: Seasonal Variation In Relation To Plant Chemical Composition And Use Of Mineral Licks, D. Fraser, B. K. Thompson, D. Arthur

Feeding Behavior Collection

Activity of moose (Alces alces) was studied at aquatic feeding areas and at natural, sodium-rich licks during four periods covering late May to early September. Aquatic feeding increased from period 1 (late May and early June) to period 2 (late June and early July) and had declined by late July. Major activity at mineral licks occurred earlier in the season than aquatic feeding, especially for males. Chemical composition of aquatic plants showed no seasonal changes corresponding to the peak of aquatic feeding in period 2, although the sodium content of some species declined in period 3. We suggest that moose …

Parental Foraging In Chipping Sparrows (Spizella Passerina), Dora Elisa Perez

Masters Theses

During the breeding season of 1982, the population of Chipping Sparrows ( Spizella passerina) that inhabits the Western Michigan University's campus was chosen to study the use of foliage and other foraging sites. Three pairs were selected to be observed intensively.

During the time the female is foraging and when the male is either foraging or in territorial advertisement activities both sexes choose needleleaf trees out of proportion to their availability.

It is also likely that in the later stages of caring for young, when food demands were highest, the birds become less selective and forage on needleleaf trees as …

The Effects Of Pentazocine And Tripelennamine On Analgesia And Locomotion, James Philip Cleary

Dissertations

The effects of pentazocine and tripelennamine, alone and in combination, were assessed on measures of analgesia (hot plate test) and locomotion (open field) in rats and mice. In Experiment 1, the combination of pentazocine and tripelennamine was found to produce analgesia at doses which were not analgesic when the drugs were given alone. This combination also reestablished analgesia in subjects made tolerant to pentazocine's effects. In Experiment 2, development of tolerance to the analgesic effects of pentazocine was delayed by addition of tripelennamine. In Experiment 3, locomotion was decreased by pentazocine at the highest dose. A similar reduction was produced …

Parallel-Arm Maze Performance Of Sighted And Blind Rats: Spatial Memory And Maze Structure, Robert H.I. Dale

Scholarship and Professional Work - LAS

Sighted and peripherally blinded groups of rats learned to obtain a small reward from each arm of an eight-arm parallel maze, and a sighted group was similarly trained on a radial maze. The parallel-sighted and parallel-blind groups were equally slow, and much slower than the radial-sighted group, to attain criterion performance. The three groups shared several response characteristics: selectively avoiding the most recently entered arms, frequently choosing adjacent arms, and an absence of 'spatial generalization' among the arms. The findings support a simple model proposing how subjects identify and choose among the maze-arms.

Compression Of The Duodenum By The Root Of The Mesentery, Peter A. Haas, Jawaid Akhtar, Lester Kobylak

Henry Ford Hospital Medical Journal

Compression of the duodenum by the root of the mesentery is a rare pathological entity that has caused much controversy because it has been mistakenly identified as the "superior mesenteric artery syndrome" or the "vascular compression of the duodenum." We discuss the pathological anatomy and the diagnosis of the disease, and report an illustrative case. Some authors report many cases of the syndrome, while others doubt its existence. Before surgery is considered, the diagnosis should be established beyond doubt and a prolonged period of observation, medical treatment, and nutritional support should be provided. The barium contrast swallowing test combined with …
