Extinction Of Fear-Potentiated Startle: Blockade By Infusion Of An Nmda Antagonist Into The Amygdala, Michael Davis, William A. Falls, Mindy Miserendino

Psychology Faculty Publications

Data derived from in vitro preparations indicate that NMDA receptors play a critical role in synaptic plasticity in the CNS. More recently, in vivo pharmacological manipulations have suggested that an NMDA-dependent process may be involved in specific forms of behavioral plasticity. All of the work thus far has focused on the possible role of NMDA receptors in the acquisition of responses. However, there are many examples in the behavioral literature of learning-induced changes that involve the reduction or elimination of a previously acquired response. Experimental extinction is a primary example of the elimination of a learned response. Experimental extinction is …

Ichthyosis: A Teacher's Manual, Deborah Brewster Vilas

Graduate Student Independent Studies

"Ichthyosis: A manual For Teachers" addresses the needs of children born with a rare, congenital skin disorder. Not unlike children with cancer, asthma or diabetes, children with ichthyosis have special needs regarding their physical comfort and safety in the educational setting. This manual addresses these needs along the developmental continuum. Using Erik Erikson's eight stages of man as a guideline, this manual addresses the physical, medical and psychosocial needs of the ichthyotic child from infancy through adolescence.

Included in this manual is an explanation of the disorder, it's symptoms and treatments. Practical tips for day care workers, teachers, school nurses …

Vocal Recognition In Mexican Free-Tailed Bats: Do Pups Recognize Mothers?, Jonathan Balcombe, Gary F. Mccracken

Sentience Collection

Mother Mexican free-tailed bats, Tadarida brasiliensis mexicana, produce 'directive' calls while searching for pups inside cave maternity roosts. These calls consist of highly repetitive pulses of sound uttered in rapid sequence. Calls are sufficiently intense that they are perceptible above the substantial background noise within roosts at distances of at least 1m. Calls are stereotyped within individuals, and statistically discriminable between individuals. These characteristics are expected for vocalizations that function for mother-pup reunions, and are shared with directive calls described previously in other bats. Mother T. b. mexicana directive calls are statistically no less discriminable than are the isolation calls …

The Ethical Judgment Of Animal Research, Shelley L. Galvin, Harold A. Herzog

Experimentation Collection

One hundred sixty subjects acted as members of a hypothetical Institutional Animal Care and Use Committee and evaluated five proposals in which animals were to be used for research or educational purposes. They were asked to approve or reject the proposals and to indicate what factors were important in reaching their ethical decisions. Gender and differences in personal moral philosophy were related to approval decisions. The reasons given for the decisions fell into three main categories: metacognitive statements, factors related to the animal, and factors related to the design of the experiment.

The Creation Of Transgenic Animal “Models” For Human Genetic Disease, Bernard Rollin

Biomedicine and Animal Models in Research Collection

Transgenic animals will be created to study human genetic disease as soon as the technological capability exists to do so. Extant laws permit such animals to be created. The mindset of the research community makes it inevitable. It is also clear that such diseases can cause enormous amounts of pain and suffering. Responsible researchers need to explore all possible avenues for controlling such pain and suffering. Thus far the research community has not engaged this issue vis a vis animals. The development of methodologies for controlling pain and suffering is likely to be exportable to numerous areas of animal research, …

G92-1078 Work And Family: Today's Juggling Act, Hrebert G. Lingren

University of Nebraska-Lincoln Extension: Historical Materials

Working families are under stress as they try to balance demands of job, children and spouse. Strategies are needed to prevent stress overload and burnout.

Over the past 25 years, women's and men's roles have changed dramatically. Today's women are better educated, have better paying jobs and are having fewer children. Women represent 45 percent of the labor force, nearly 80 percent work outside the home and 75 percent of mothers of young children are employed.

As women have entered and stayed in the work force in ever-increasing numbers, the dual-earner family has emerged. Married couple earners comprise more than …

G92-1117 The Sandwich Generation: A Cluttered Nest, Herbert G. Lingren, Jayne Decker

University of Nebraska-Lincoln Extension: Historical Materials

The needs of three generations and solutions to resolve their stresses are covered here.

Lisa and Bruce both have careers. They have a teen-age son, a college student daughter, a recently divorced daughter with a one-year-old child, and an elderly mother who needs an increasing amount of caregiving, all living in the same household. They are classic members of the sandwich generation.

In the 1990s, people live longer, they postpone marriage, more children are living at home to go to college, and an increasing number of adult children are returning home after a divorce or loss of job. Consequently, larger …

Social Preference Of Four Cross-Foster Reared Sandhill Cranes, Thomas A. Mahan, Brenda S. Simmers

Proceedings of the North American Crane Workshop

Four greater sandhill cranes (Grus canadensis tabida) were hatched and reared individually by 4 non-sandhill crane pairs: 2 by white-naped crane (G. vipio) pairs, 1 by a Siberian crane (G. leucogeranus) pair, and 1 by a red-crowned crane (G. japonensis) pair. After 1 year the sandhill cranes (2 male and 2 female) were placed in enclosed pens adjacent to an oppositesexed, same-age bird of the foster species on 1 side and an opposite-sexed, same-age conspecific on the other side. Data were collected throughout 1 year and included proximity between test and choice …

Methodology, description of the students, results, and personal responses to the fitness program are described. outcomes include a slight decrease in body fat and an increase in cardiovascular fitness as measured by oxygen intake. Although a formal measure of self esteem did not show changes over the course of the study, students report positive attitude changes. An …

Territorial Behavior Of Florida Sandhill Cranes In The Okefenokee Swamp, Laurel A. Bennett, Alan J. Bennett

Proceedings of the North American Crane Workshop

Intraspecific and territorial interactions of adult Florida sandhill cranes (Grus canadensis pratensis) were studied in the Okefenokee Swamp, Georgia 1985-87. Adult pairs occupied exclusive and defended territories year round. We did not observe social behavior or flocking by adult cranes. Reproductive success did not influence the fidelity of pairs to their territories or aggressiveness toward other cranes. Females that lost mates retained their territories and eventually re-paired. Territorality was most intense during fall and winter and may have been necessary to maintain feeding areas. Habitat conditions in the Okefenokee Swamp may dictate territorality, not sociality, as a strategy …

Trypanosome Infection Rates In Tsetse Flies (Diptera: Glossinidae) And Cattle During Tsetse Control Operations In The Kagera River Region Of Rwanda, Steve Mihok, Leonard H. Otieno, Christopher S. Tarimo

All Peer-Reviewed Publications

Trypanosome infections were monitored in three species of tsetse fly (Glossina pallidipes Austen, G. morsitans centralis Machado, and G. brevipalpis News-tead) at four locations in the Kagera River region of Rwanda from May 1989 to September 1990. Two of the four areas (Mpanga Ranch and Bukora Ranch) were subjected to tsetse fly suppression operations with odour-baited traps. Proboscis infections of the Trypanosoma congolense and T. vivax types accounted for roughly equal numbers of the 207 mature infections detected (3.8%). Variation in infection rates was area-specific rather than tsetse species-specific. Order of magnitude differences in tsetse fly densities among areas were …

Oviposition, Larval Arrest And Establishment Of Chilo Partellus (Lepidoptera: Pyralidae) On Maize Genotypes During Anthesis, Harish Kumar

All Peer-Reviewed Publications

The oviposition, larval arrest and establishment by the stem borer Chilo partellus (Swinhoe) were measured on different maize genotypes during anthesis. The maize genotypes tested were: Inbred A (Susceptible), Mp 704, MBR-8637, MBR-8650, MBR-8668, Poza Rica 7832, ER-29 SVR, Katumani Composite B, MMV 400, Bulk CG 4141, and ICZ2-CM. The moths oviposited on the middle leaves of the plant and the neonate larvae moved to leaf sheaths and ear husks to feed (arrest). As they grew older, the larvae invaded the stem, ear shanks and tassel to complete feeding (establishment) and to pupate. The response of the stem borer differed …

Bulletin No 4131- Electric Fencing, Dean Maughan

Bulletins 4000 -

Fencing has always been an integral part of our agricultural system. We need fences for stock control and pasture management. Traditionally, fences have been strong and robust physical barriers. The strength and height of the fence kept domestic animals confined. For many years, conventional fences have served the farmer well. However because returns from livestock over the past ten years have been variable and because of the current cost/ price squeeze, electric fencing, as a cheaper form of fencing, has gained popularity.

Strike-Induced Chemosensory Searching: Variation Among Lizards, Royce E. Ballinger, Nathaniel R. Coady, Joseph M. Prokop, Julio A. Lemos-Espinal

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Strike-induced chemosensory searching (SICS) was found in two families of lizards (Teiidae, Anguidae) but not in two other lizard families (Scincidae, Iguanidae). Experiments on another family (Xenosauridae) were inconclusive as to its possession of SICS. The rate of tongue-flicking was significantly increased after a simulated prey strike compared to controls in Cnemidophorus sexlineatus and Barisia imbricata. SICS may be part of a complex foraging strategy evolved in certain reptiles rather than part of a generalized chemosensory behavior because two species of skinks did not exhibit SICS in spite of a well developed vomeronasal olfactory apparatus and known abilities to …

Disruption Of Glossina Morsitans Morsitans (Diptera: Glossinidae) Eclosion Behaviour: A Novel Method For Evaluating The Action Of Neurotoxic Agents, J. Ždárek, D. L. Denlinger

All Peer-Reviewed Publications

As the tsetse fly, Glossina morsitans morsitans Westwood extricates itself from the puparium and moves upward through the soil the ptilinum expands and contracts rhythmically and thus generates a stereotypic behavioural pattern that persists for up to 10 h if the tsetse fly remains confined. The response, which is easily recorded tensometrically from the movements of the ptilinum, can be exploited as a tool for evaluating the behavioral response of tsetse flies to various neurotoxic agents. The behavioural assay proves useful in providing precise information about the latency of the response and lethal time, and can suggest likely modes of …

Factors Affecting Seasonal Dispersal Of The Tsetse Flies Glossina Pallidipes And G. Longipennis (Diptera: Glossinidae) At Nguruman, South-West Kenya, R. Brightwell, R. D. Dransfield, B. G. Williams

All Peer-Reviewed Publications

Seasonal changes in the distribution of the tsetse flies, Glossina pallidipes Austen and G. longipennis Corti, along a transect from riverine thickets out into open plains were monitored along with tsetse density, climatic factors, vegetation and host abundance. Dispersal of tsetse into open country was quantified using the mean spread. During and after the rains both species extended their distribution out into open country up to at least 3.5 km from riverine thicket areas. The mean spread of G. longipennis was greater than that of G. pallidipes. The spread of males and females was very similar, as was the spread …

Charles Rueben Keyes And The History Of Iowa Archaeology, William Green

Journal of the Iowa Academy of Science: JIAS

Charles Reuben Keyes (1871-1951) achieved recognition during his lifetime as the "founding father" of Iowa archaeology, and later assessments confirmed and reemphasized Keyes' stature as Iowa's pioneer archaeologist. The collections and documents Keyes compiled, his interpretive publications, and the records of field work he coordinated have proven more valuable to Midwest and Plains archaeology every year. This article emphasizes Keyes' involvement in the development of professionalism in American archaeology and Iowa’s position in the growth of the discipline from 1920 to 1950. Keyes' contacts with the principal archaeologists of his era ensured Iowa’s involvement in the development of survey methods …

Evidence That Nicotine Can Acutely Desensitize Central Nicotinic Cholinergic Receptors In Vivo, John Randolph James

Theses and Dissertations

Current concepts concerning nicotine's central nervous system (CNS) mechanism(s) of action suggest that this drug is producing its effects via an interaction at nicotiniccholinergic receptors (nAChRs) which open a membrane cation channel. Following initial opening of the channel, nicotine appears to induce a rapid desensitization of the nAChRs, closing the channel and resulting in a cessation of nicotine's effects. Research presented here will provide evidence of this secondary desensitization process in vivo by demonstrating nicotine's ability to induce acute tolerance in the discriminative stimulus (DS) paradigm. The ability of nicotine to elicit DS control of behavior was significantly reduced via …

The Effects Of Ingested Carbonation On Oxygen Transport And Ventilation In Trained Distance Runners, Stacy Jean Ingraham

Dissertations and Theses @ UNI

The purpose of this study was to examine the effect of consumption of carbonated beverages on maximal aerobic capacity, as measured by maximal oxygen consumption (VO2MAX), and respiratory physiology, as measured by ventilation frequency (f), ventilatory equivalent for oxygen and carbon dioxide (O2VE, co2VE), expired minute ventilation (VE), carbon dioxide output (VCO2), respiratory exchange ratio (RER), and tidal volume (VT).

Thirteen male high school, collegiate and post collegiate distance runners from the local community performed two maximal treadmill tests exactly one week apart, following two different fluid ingestion treatments. The subjects were randomly assigned to a carbonated beverage or noncarbonated …

Consumption Of Solid Food By Suckling Pigs: Individual Variation And Relation To Weight Gain, Edmond A. Pajor, David Fraser, Donald L. Kramer

Feeding Behavior Collection

Individual daily consumption of supplementary solid food ('creep feed') was measured from Day 10 to weaning at Day 28 for 39 piglets in four litters, and its relationship to body weight and weight gain up to Day 42 was investigated. Individual consumption was measured by combining the weight of the feed removed from the dispensers (monitored electronically) and a video image of piglet activity at the feeder. Creep feed consumption varied greatly, both between and within litters. On average, pigs began feeding on Day 12 (range Day 10-28), intake was relatively low (usually < 5 g day ^‒1) until Day 20 but increased …
