Predictors Of Social Physique Anxiety In Adolescent Swimmers With Physical Disabilities, Jeffrey J. Martin

Kinesiology, Health and Sport Studies

The purpose was to examine predictors of social physique anxiety (SPA) in adolescent swimmers with physical disabilities. Participants were 57 swimmers (27 females, 30 males, ages 16-19, M = 16.2) with various physical disabilities. A three-way ANOVA revealed significant differences in SPA between countries and among disabilities but not gender. Stepwise multiple regression results indicated that self-esteem and the self-identity subscale of the Athletic Identity Measurement Scale (AIMS) were the best predictors of SPA but that gender, country, and type of disability were not significant.

G99-1397 Motivating Your Employees, John E. Barbuto, Jr., Lance L. Brown

University of Nebraska-Lincoln Extension: Historical Materials

The ability to motivate employees is often the difference between extraordinary and mediocre leadership. This guide provides a useful tool for understanding and motivating employees.

Leaders who are able to motivate their workers will have a better chance of reducing the typical labor problems faced in today's economy (turnover, absenteeism and low productivity). In the past, when the state's economy was weaker than it is today, agricultural leaders didn't have to worry about these labor issues because there were plenty of workers to choose from. Because of the expansion of agricultural enterprises and Nebraska's exceptionally low unemployment rate, finding, keeping …

G99-1392 "Fighting Fair" In Marriage, Herbert G. Lingren

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide presents steps to follow to recognize and resolve marital conflicts through negotiation and finding mutually agreeable alternatives.

Do you ever use extreme or irrational tactics to gain your point (slamming doors, stomping around)?

Do you sometimes hurt your spouse in order to have the last word (sarcasm, name-calling)?

Do you store up grudges and use them to "hit" your partner over the head at a later time (revenge)?

Is your attitude "If I don't get what I want, I will quit cooperating?"

Do you continually expect others to do things the "right way" (your way)?

If you answered …

Caudal Distraction By Rat Snakes (Colubridae, Elaphe): A Novel Behavior Used When Capturing Mammalian Prey, Stephen J. Mullin

Faculty Publications

Caudal movement in snakes may serve either a predatory (e.g., caudal luring) or defensive (eg., rattling, aposematism) function. I describe a new behavioral pattern of tail movement in snakes. Gray rat snakes (Elaphe obsoleta spiloides) foraging on small mammals (Mus domesticus) moved their tails in an erratic, whiplike fashion after detecting their prey in the vicinity. The thrashing movement in the horizontal plane was audibly and visually obvious, resulting in displacement of leaf litter around the tail. All subjects displayed the behavior, but not in all foraging episodes. Shorter durations of caudal distraction resulted in greater …

Conditioned Food Aversions: Principles And Practices, With Special Reference To Social Facilitation, Michael H. Ralphs, Frederick D. Provenza

Behavioral Education for Human, Animal, Vegetation, and Ecosystem Management (BEHAVE)

Conditioned food aversion is a powerful experimental tool to modify animal diets. We have also investigated it as a potential management tool to prevent livestock from grazing poisonous plants such as tall larkspur (Delphinium barbeyi), white locoweed (Oxytropis sericea) and ponderosa pine (Pinus ponderosa) on western US rangelands. The following principles pertain to increasing the strength and longevity of aversions: mature animals retain aversions better than young animals; novelty of the plant is important, although aversions can be created to familiar plants; LiCl is the most effective emetic, and the optimum dose for cattle …

Behavioral Interactions And Conflict Among Domestic Dogs, Black-Tailed Prairie Dogs, And People In Boulder, Colorado, Marc Bekoff, Robert W. Ickes

Ethology Collection

Interactions among domestic dogs (Canis familiaris), black-tailed prairie dogs (Cynomys ludovicianus), and people were studied at Dry Creek, Boulder, Colorado. Our objective was to develop a basic understanding of the nature of dog–prairie dog interactions in this recreational area, because this is an issue that has high visibility and over which there is conflict in Boulder: There are those who want dogs to run free regardless of their impact on the behavior and lives of prairie dogs and those who want to protect prairie dogs and have dogs restrained or go elsewhere. We found that dogs clearly influenced the behavior …

The Effect Of Proximity On Landmark Use In Clark’S Nutcrackers, Kristy L. Gould-Beierle, Alan Kamil

Avian Cognition Papers

Clark’s nutcrackers, Nucifraga columbiana, store thousands of pine seeds during the autumn and retrieve them throughout the winter. It has been shown that these birds are able to use visual cues to relocate hidden food in the laboratory. In this set of experiments, we trained three groups of Clark’s nutcrackers to find a hidden food goal that was placed in the same spatial location relative to the testing room. During training, the location of two local cues in relation to the goal differed between the three groups. Group 1 learned the task with the cues closest to the goal, group …

Searching Image In Blue Jays: Facilitation And Interference In Sequential Priming, Alan B. Bond, Alan C. Kamil

Papers in Behavior in Biological Sciences

Repeated exposure to a single target type (sequential priming) during visual search for multiple cryptic targets commonly improves performance on subsequent presentations of that target. It appears to be an attentional phenomenon, a component of the searching image effect. It has been argued, however, that if searching image is an attentional process, sequential priming should also interfere with performance on subsequent nonprimed targets, and such interference has never been unequivocally demonstrated. In blue jays (Cyanocitta cristata) searching in an operant apparatus for targets derived from images of cryptic moths, detection performance was strongly facilitated in the course of …

Patterns Of Movement And Orientation During Caching And Recovery By Clark’S Nutcrackers, Nucifraga Columbiana, Alan Kamil, Russell P. Balda, Sally Good

Avian Cognition Papers

Clark’s nutcrackers regularly store large numbers of pine seeds and remember the locations of the cached seeds. Although they are very accurate, they do make some errors during recovery. In an attempt to determine whether any behaviours during caching predicted the occurrence of errors during recovery, we videotaped Clark’s nutcrackers while they cached and recovered seeds under laboratory conditions. We used the videotapes to develop complete, quantitative descriptions of caching and recovery behaviour, with an emphasis on body orientation and directions of movement. During caching, the birds showed the greatest change in their orientation and direction following cache creation. During …

How Do They, Indeed? A Reply To Biegler Et Al., Alan Kamil, Juli E. Jones

Avian Cognition Papers

We trained Clark’s nutcrackers, Nucifraga columbiana, to search halfway between two landmarks while varying the distance between the landmarks (Kamil & Jones 1997). We found that the birds learned the problem readily and generalized to novel interlandmark distances within the range of distances used during training. Unlike some other studies in which responses to proportional distance were obtained (e.g. O’Keefe & Burgess 1996; Tommasi et al. 1997), the nutcrackers showed very precise search and maintained this precision during the transfer test. The distributions of digging locations around the central position were concentrated within ±1–2 cm of the central location …

Sociality And Social Learning In Two Species Of Corvids: The Pinyon Jay (Gymnorhinus Cyanocephalus) And The Clark’S Nutcracker (Nucifraga Columbiana), Jennifer J. Templeton, Alan Kamil, Russell P. Balda

Papers in Behavior in Biological Sciences

The hypothesis that social learning is an adaptive specialization for social living predicts that social species should learn better socially than they do individually, but that nonsocial species should not exhibit a similar enhancement of performance under social learning conditions. The authors compared individual and social learning abilities in 2 corvid species: the highly social pinyon jay (Gymnorhinus cyanocephalus) and the less social Clark’s nutcracker (Nucifraga columbiana). The birds were tested on 2 different tasks under individual and social learning conditions. Half learned a motor task individually and a discrimination task socially; the other half learned …

Female Responses To Isolated Signals From Multimodal Male Courtship Displays In The Wolf Spider Genus Schizocosa (Araneae: Lycosidae), Eileen Hebets, George W. Uetz

Eileen Hebets Publications

Male wolf spiders within the genus Schizocosa display considerable variation in foreleg ornamentation as well as in courtship communication. Multiple modes of male signaling have evolved in a number of species. Divergence in courtship signals among species within this genus may be directly associated with variation in the sensory sensitivities of conspecific females. We isolated the visual and vibratory courtship cues of four species of Schizocosa and recorded conspecific female receptivity to each isolated cue. We also examined female receptivity to complete multimodal courtship signals. We found that the sensory sensitivities of conspecific females were associated with the predominant modes …

Influences Of Relative Humidity, Soil And Air Temperatures, And Lunar Phase On Occurrence Of Terrestrial Plethodontid Salamanders At High Elevation Sites, Jo Santiago

Theses, Dissertations and Capstones

Microhabitat environments and occurrences of terrestrial plethodontid salamanders including Plethodon nettingi Green, Plethodon cinereus (Green), Plethodon wehrlei Fowler and Dunn, Plethodon glutinosus (Green), and Desmognathus ochrophaeus Cope were monitored over a 15 month period at high elevation sites in the Stuart Knob area of the Monongahela National Forest in eastern West Virginia. Environmental data collected for eight equal-sized study plots (8m² ) included relative humidity, air and soil temperatures, and lunar phase. Five hundred and twenty-five salamanders were captured in diurnal and nocturnal searches, and an additional 52 individuals were observed. It was found that the most common occurring …

Responses Of Glossina Fuscipes Fuscipes (Diptera: Glossinidae) And Other Diptera To Carbon Dioxide In Linear And Dense Forests, M. M. Mohamed-Ahmed, S. Mihok

All Peer-Reviewed Publications

The responses of Glossina fuscipes fuscipes Newstead and other Diptera to carbon dioxide were studied in linear and dense forests along the shores of Lake Victoria, Kenya. Flies were caught in biconical traps and were intercepted with electric nets while in flight near traps. Carbon dioxide dispensed at a high rate (51 min-1) in linear forest failed to increase the numbers of tsetse attracted to or caught in traps. In contrast, catches of non-biting Muscidae, Stomoxyinae and Tabanidae were improved by up to 11 times. Inside dense forest, carbon dioxide released at half this rate increased both the numbers of …

Potential Associations Among Genetic Markers In The Serotonergic System And The Antisocial Alcoholism Subtype, E. M. Hill, S. F. Stoltenberg, M. Burmeister, M. Closser, R. A. Zucker

Department of Psychology: Faculty Publications

Alcoholism is transmitted in families. The complexity and heterogeneity of this disorder has made it difficult to identify specific genetic correlates. One design with the potential to do so is the family-based association study, in which the frequencies of genetic polymorphisms are compared between affected and nonaffected members. Reduced central serotonin neurotransmission is associated with features of an antisocial subtype of alcoholism, although a primary deficit has not been traced to a particular component. Genetic markers related to the serotonergic system have been identified, located, and cloned. If associations can be discovered, the development process for pharmacotherapy could be facilitated. …

Prediction Accuracy Of Young And Middle-Aged Adults In Memory For Familiar And Unfamiliar Texts, Sarah K. Johnson, Andrea R. Halpern

Faculty Journal Articles

This study investigated the influence of age, familiarity, and level of exposure on the metamemorial skill of prediction accuracy on a future test. Young (17 to 23 years old) and middle-aged adults (35 to 50 years old) were asked to predict their memory for text material. Participants made predictions on a familiar text and an unfamiliar text, at three different levels of exposure to each. The middle-aged adults were superior to the younger adults at predicting performance. This finding indicates that metamemory may increase from youth to middle age. Other findings include superior prediction accuracy for unfamiliar compared to familiar …
