Vocal Learning In Grey Parrots (Psittacus Erithacus): Effects Of Social Interaction, Reference, And Context, Irene M. Pepperberg

Sentience Collection

For many passerines, the extent,timing, and even presence of allospecific vocal learning can be influenced by the form of input that is received. Little data exist, however, on vocal learning in parrots (Psittacidae). I have previously proposed that such vocal learning proceeds most readily when input is (1) referential, (2) contextually applicable, and (3) interactive. The referential aspect demonstrates the meaning of the code to be taught, the contextual aspect demonstrates the use that can be made of the information contained in the code, and the interactive aspect provides explicit training that is constantly adjusted to the level of the …

Technology Transfer: A View From The Trenches, Harvey Drucker

RISK: Health, Safety & Environment (1990-2002)

Dr. Drucker, who has lab-wide responsibility for technology transfer at Argonne National Laboratory, argues that transferring rights in discoveries made through tax supported research to private entities can contribute to public welfare in many ways.

Numerical Competence In An African Gray Parrot (Psittacus Erithacus), Irene M. Pepperberg

Sentience Collection

An African gray parrot (Psittacus erithacus), Alex, trained to label vocally collections of 1-6 simultaneously presented homogeneous objects, correctly identified, without further training, quantities of targeted subsets in heterogeneous collections. For each test trial Alex was shown different collections of 4 groups of items that varied in 2 colors and 2 object categories (e.g., blue and red keys and trucks) and was asked to label the number of items uniquely defined by the conjunction of 1 color and 1 object category (e.g., "How many blue key?"). The collections were designed to provide maximal confounds (or distractions) and thus replicate the …

The Relationship Between Creep Feeding Behavior Of Piglets And Adaptation To Weaning: Effect Of Diet Quality, David Fraser, J. J.R. Feddes, E. A. Pajor

Feeding Behavior Collection

Individual variation in creep feed intake and its relation to adaptation to weaning were studied in piglets weaned at 4 wk of age. The animals received either a "low-complexity" creep-starter diet based on corn, barley and soybean meal (12 litters), or a "high-complexity", medicated, commercial diet without soybean meal (12 litters). Diets were fed as creep feed during the 2 wk before weaning, and as the sole diet during the 2 wk after weaning. Creep feeding behavior of piglets was monitored by video recording. Pigs fed the high-complexity diet consumed more creep feed (P < 0.05), tended to gain more during the week before weaning (P < 0.10), and converted feed more efficiently and gained more weight in the 2 wk after weaning (P < 0.01). Use of creep feed varied greatly among individual littermates. Multiple regression analysis showed that on the high-complexity diet, pigs that used creep feed more than their littermates tended to be those with low gains in weeks 1-3 after birth (P < 0.001), and tended to gain more weight during the week before and during the 2 wk after weaning (P < 0.01). The trends were consistent but weaker with the low-complexity diet. However, predictive power was low, with creep feeding accounting for only 4% of individual variation in post-weaning gain on the high-complexity diet and 1% on the low. Regardless of diet quality, therefore, creep feeding remained highly variable and only weakly related to weight gains during the 2 wk after weaning.

The Effects Of Requiring Different Response Strategies Following Caching In Clark’S Nutcrackers (Nucifraga Columbiana), Alan Kamil, Russell P. Balda, Deborah J. Olson

Papers in Behavior in Biological Sciences

Clark’s nutcrackers use spatial memory to recover stored food in the field and have performed very well in laboratory tests of spatial memory. During the present experiment, two groups of nutcrackers cached seeds every 4 days. Following each cache session, the stay group was tested with seeds in their caches; the shift group found seeds in novel sites. The stay group performed accurately throughout the experiment, but the shift group gave no indication of being able to learn to avoid sites where they had stored seeds. These results suggest that although nutcrackers can learn to shift away from remembered locations …

Public Attitudes Toward Animal Research: Some International Comparisons, Ralph Pifer, Kinya Shimizu, Linda Pifer

Attitudes Toward Animal Research Collection

A comparative analysis was made of the public's attitudes toward the use of animals in scientific research in 15 different nations. The intensity of opposition to animal research was found to vary from relatively low levels in Japan and the United States to much higher levels in France, Belgium, and Great Britain. More women than men were opposed to animal research in all 15 nations. Scientific knowledge, or the lack of knowledge, was not found to have a consistent relationship with attitudes toward animal research. Concern about the environment was found to be related to opposition to animal research in …

Concepts Of Animal Well-Being And Predicting The Impact Of Procedures On Experimental Animals, D. J. Mellor, C. S. W. Reid

Experimental Research and Animal Welfare Collection

1. We argue that:

• in their application to non-human animals, 'welfare' and 'well-being' are interchangeable words; and that

• good welfare/well-being is the state of being manifest in an animal when its nutritional, environmental, health, behavioural and mental needs are met.

2. These latter are essentially the 'five freedoms' formulated by the Farm Animal Welfare Council of the United Kingdom.

3. Using the five freedoms as a basis, we have developed a system for assessing the impact of a proposed animal experiment or usage. The freedoms are now transformed into 'domains of potential compromise' and are redefined better to …

Predicting The Past, Recounting The Future: Human Ecology And A Prehistory Of Consciousness, Paul Faulstich

Pitzer Faculty Publications and Research

This paper is concerned with the organic derivation and primary meaning of Pleistocene finger flutings; I propose that in order to gain insight into the significance of the flutings, we must attempt an understanding of the physical and mental contexts in which they emerged. I suggest that finger flutings provided a cultural record in the Pleistocene which documented thought and action, and made it ready for reflection. Through the process of finger fluting, the human 'self' was objected and reality was modified in the experience of self-consciuosness. I argue that finger flutings, like language, were employed to discover and convey …

G94-1227 Preparation For Retirement: Planning When Still Employed, George P. Rowe

University of Nebraska-Lincoln Extension: Historical Materials

Retirement preparation includes planning for financial security, health maintenance, a social network, and meaningful activities.

Retirement is defined as partial or complete withdrawal from career work accompanied by a change in the sources and amount of income. Most persons choose to retire today between the ages of 62 and 66 since eligibility for partial Social Security benefits begins at age 62 with full benefits available by age 65. Full benefits will begin later for Americans born after 1959 when they reach age 67 in 2027. For most occupations, there is no mandatory age at which people have to quit working. …

A Biosystematic Study Of Three Plant Pathogenic Fungi, Richard James Langham

Masters Theses

Isolates of Chalara australis, Eucalypt Ceratocystis, and Ceratocystis virescens were grown on Potato Dextrose Agar, Malt Extract Agar, and Czapek Agar and examined as part of a biosystematic study on these fungi. Basic micromorphological and macromorphological data on the cultures were recorded and the taxa were found to be morphologically similar. Tissue isolates and single spore isolates were crossed within these taxa and an interspecific cross performed. Chalara australis was found to be either asexual or have only one mating type present in the cultures studied. Eucalypt Ceratocystis was found to have a mating system characteristic of bipolar …

Detection Of Trypanosome Infections In The Saliva Of Tsetse Flies And Buffy-Coat Samples From Antigenaemic But Aparasitaemic Cattle, P. A.O. Majiwa, R. Thatthi, S. K. Moloo, J. H.P. Nyeko

All Peer-Reviewed Publications

Relatively simple protocols employing non-radioactive DNA probes have been used for the detection of African trypano-somes in the blood of mammalian hosts and the saliva of live tsetse flies. In combination with the polymerase chain reaction (PCR), the protocols revealed trypanosomes in buffy-coat samples from antigenaemic but aparasitaemic cattle and in the saliva of live, infected tsetse flies. Furthermore, the protocols were used to demonstrate concurrent natural infections of single tsetse flies with different species of African trypanosomes. © 1994, Cambridge University Press.

Bulletin 4270 - Meat Quality In Beef Cattle, Brian Mcintyre

Bulletins 4000 -

Meat quality is the sole concern of the consumer once the product reaches the supermarket shelf. Breeding, feeding or any other factors that may have been important to the beef producer have no influence over the buyer's choice. Meat quality can be divided into two components — appearance and eating quality.

Performance Of Four Seed-Caching Corvid Species In The Radial-Arm Maze Analog, Alan Kamil, Russell P. Balda, Deborah J. Olson

Papers in Behavior in Biological Sciences

Four seed-caching corvid species were tested in an open-room analog of the radial-arm maze. During Experiment 1, the species more dependent on stored food, Clark’s nutcrackers (Nucifraga columbiana) and pinyon jays (Gymnorhinus cyanocephalus), acquired the task more quickly and to higher accuracy levels than either scrub jays (Aphelocoma coerulescens) or Mexican jays (A. ultramarina). During Experiment 2, performance after retention intervals was tested. When intervals of 30-210 min were tested in ascending order, species differences observed during acquisition were again obtained. However, when intervals of 5-300 min were tested in random order, …

Toward An Understanding Of Alzheimer's Disease: The Effects Of B-Amyloid(1-42) And Ibotenic Acid On The Retention Of A Spatial Learning Task In Rats F:Ollowing Multiple Injections Into The Hippocampus, Jason Pequette '94

Honors Projects

Neuropathologically, Alzheimer's disease (AD) is characterized by neuritic plaques and neurofibrillary tangles. Evidence has suggested that a protein called B-amyloid (BA) is a major component of the neuritic plaques and may playa role in the neurodegeneration seen in AD. The cellular mechanisms by which BA induces neurotoxicity, however, are still unclear. Recent evidence suggests that the aggregational state of BA may be relevant to its neurotoxicity. Whether portions of the BA protein or the entire sequence produces neurotoxicity in neurons, however, remains a controversy. Still another controversy is whether BA is directly neurotoxic to neurons or whether it increases the …

Distribution And Sampling Of Chilo Partellus (Lepidoptera: Pyralidae) In Maize And Sorghum On The Kenya Coast, W. A. Overholt, K. Ogedah, P. M. Lammers

All Peer-Reviewed Publications

The seasonal occurrence and spatial distribution of the crambine stem borer, Chilo partellus (Swinhoe) were investigated in maize, Zea mays, and sorghum, Sorghum bicolor, fields at the Kenya coast. During the vegetative growth stage, small-sized larvae were typically found behind leaf sheaths and in whorls in maize and sorghum. In reproductive and senescent maize, small-sized larvae were also found feeding in ears. Later immature life stages were located predominantly in stems in sorghum, and in the stems and ears in maize. Density and variance estimates of small, medium-, and large-sized larvae and pupae in maize and sorghum were fitted to …

Comparative Evaluation Of Commercially Grown Lupin And Mung Sprouts, Sant B. Kaur

Theses: Doctorates and Masters

More than one million tonnes of lupin seed are produced per annum in Western Australia. Lupin can be considered as an alternative to staple pulse food items such as soybeans, peas, chick peas and mung beans. This research was designed to provide potential investors with objective scientifically obtained evidence of the feasibility, and marketing potential, of using lupin as a basis for the commercial development of value added foods, in this case commercially grown lupin sprouts. Sprouts were selected because sprouted lupins are comparable with mung bean sprouts, the market leader, as regards yield and consumer acceptance as a food …

Co-Sensitization Of Dopamine And Serotonin Receptors Occurs In The Absence Of A Change In The Dopamine D1 Receptor Complex After A Neonatal 6-Ohda Lesion, Li Gong

Electronic Theses and Dissertations

To test whether SKF 38393 could ontogenetically sensitize dopamine (DA) D$\sb1$ receptors and whether this sensitization would be associated with biochemical changes, intact and neonatal 6-hydroxydopamine (6-OHDA)-lesioned rats (200 $\mu$g i.c.v.) were treated daily from birth with SKF 38393 (3.0 mg/kg i.p. x 28 days) or its vehicle. In DA D$\sb1$ neonatally sensitized 6-OHDA rats, enhanced locomotor responses were observed with the first SKF 38393 challenge dose (3.0 mg/kg i.p.) at 6 weeks. This response increased further with weekly SKF 38393 treatments. Enhanced stereotyped behaviors were seen in both lesioned and sensitized rats at 8 weeks. There was no change …
