Prediction Of Stress Appraisals From Mastery, Extraversion, Neuroticism, And General Appraisal Tendencies, S. H. Hemenover, Richard A. Dienstbier

Department of Psychology: Faculty Publications

Several personality dimensions (mastery, extraversion, and neuroticism) and a new General Appraisal Measure were used to predict stress appraisals made by college students in specific situations. Using multiple-regression techniques, mastery and general appraisal tendencies predicted appraisals for an intellectual task. Path analysis supported a structural model with general appraisal tendencies as a mediator between mastery and specific appraisal. In the second study mastery, extraversion, neuroticism, and general appraisal tendencies predicted appraisals for an academic stressor. Path analysis again supported the mediational nature of general appraisal tendencies from personality variables to specific appraisal. We discuss a potential causal mechanism between personality …

Use Of Folk Healing Practices By Hiv-Infected Hispanics Living In The United States, Mariana Suarez, Marcela Raffaelli, Ann O'Leary

Department of Psychology: Faculty Publications

In the absence of a medical cure for AIDS, HIV-infected individuals may seek alternative treatments that are consistent with cultural and social beliefs. This paper examines beliefs about, and use of, folk healing practices by HIV-infected Hispanics receiving care at an HIV/AIDS clinic in inner-city New Jersey. Anonymous individual interviews were conducted with 58 male and 18 female HIV-infected Hispanics aged 23-55, primarily of Puerto Rican origin (61%) or descent (29%). The majority of respondents believed in good and evil spirits (73.7%); among the 56 believers, 48% stated that the spirits had a causal role in their infection, either alone …

The Right To A Family Environment For Children With Disabilities, Victoria Weisz

Department of Psychology: Faculty Publications

To access services for children with disabilities, the children often have been required to leave their families of origin. However, social science evidence indicates that there are substantial psychological benefits for children to remain with their families whenever possible. The UN Convention on the Rights of the Child (UN General Assembly, 1989) supports policies and programs that enable children with disabilities to receive services without leaving their family environment. This article briefly reviews the social science literature and the UN. Convention, and it documents trends in US. law consistent with the implications of the scientific evidence and international consensus. The …

The Effects Of An Appraisal Manipulation: Affect, Intrusive Cognitions, And Performance For Two Cognitive Tasks, Scott H. Hemenover, Richard A. Dienstbier

Department of Psychology: Faculty Publications

We examined the relationship between trait measures of general appraisal and test anxiety, state measures of stress appraisals, affect, and intrusive cognition, andperformance measures on two cognitive tests (mental math and Raven matrices). Participants were randomly assigned to threat, challenge, or control conditions that were created by manipulating both primary and secondary appraisals. We predicted that the threat condition would lead to more negative affect, stress appraisals, intrusive cognitions, and more errors. While our manipulated conditions led to inconsistent effects, path analyses tended to confirm predictions that negative task appraisals and trait test anxiety lead to negative affect and to …

The Relations Of Children’S Dispositional Prosocial Behavior To Emotionality, Regulation, And Social Functioning, Nancy Eisenberg, Richard A. Fabes, Mariss Karbon, Bridget C. Murphy, Marek Wosinski, Lorena Polazzi, Gustavo Carlo, Candy Juhnke

Department of Psychology: Faculty Publications

The purpose of this study was to examine the relations of a measure of children’s dispositional prosocial behavior (i.e., peer nominations) to individual differences in children’s negative emotionality, regulation, and social functioning. Children with prosocial reputations tended to be high in constructive social skills (i.e., socially appropriate behavior and constructive coping) and attentional regulation, and low in negative emotionality. The relations of children’s negative emotionality to prosocial reputation were moderated by level of dispositional attentional regulation. In addition, the relations of prosocial reputation to constructive social skills and parent-reported negative emotionality (for girls) increased with age. Vagal tone, a marker …

Lung And Nasal Lesions Caused By A Swine Chlamydial Isolate In Gnotobiotic Pigs, Douglas G. Rogers, Arthur A. Andersen, Breck D. Hunsaker

School of Veterinary and Biomedical Sciences: Faculty Publications

The objective of this study was to determine whether a chlamydial isolate recovered from nasal swabs from swine with pneumonia could cause pneumonia and rhinitis in gnotobiotic pigs. The identity of the isolate currently is unknown, but it shares characteristics with Chlamydia trachomatis. After propagation in Vero cells and preparation of the inoculum (2.5 x 1010 inclusion-forming units/ml), Chlamydiae were instilled into nostrils (1.0 ml/nostril) and lungs (2.0 ml intralaryngeally) of 15 anesthetized 3-day-old gnotobiotic piglets. Five age-matched gnotobiotic piglets were anesthetized and sham infected with uninfected cell culture lysates. Two treated piglets were moribund and 2 were severely …

Intestinal Lesions Caused By Two Swine Chlamydial Isolates In Gnotobiotic Pigs, Douglas G. Rogers, Arthur A. Andersen

School of Veterinary and Biomedical Sciences: Faculty Publications

The objective of this study was to determine whether 2 distinct chlamydial isolates recovered from the intestines and feces of diarrheic nursery pigs could cause intestinal lesions in gnotobiotic pigs. Both isolates share biological characteristics with Chlamydia trachomatis. Chlamydial isolates R27 and R19 were propagated in Vero cells or embryonated eggs, respectively, and suspended in sucrose-phosphate-glutamine buffer with 10% fetal bovine serum for inoculation. Sham inocula were prepared from uninfected cell culture lysates and from uninfected eggs. Each piglet was fed 1 ml of inoculum or sham inoculum at 3-4 days of age. Ten piglets were each fed 10 …

Communicating Violence Risk Assessments, Thomas Grisso, Alan Tomkins

Department of Psychology: Faculty Publications

Recent developments in the law have made the assessment of risk of violence a required professional ability for every clinical psychologist. About 30 years ago, laws controlling involuntary civil commitment evolved to require more than merely a finding of mental illness. They also required evidence that patients, if not committed, would be dangerous to themselves or to others. During that era, states also developed laws that made it mandatory for clinicians to report evidence if their child clients, the children of their adult clients, and disabled or older adults were in danger of abuse by their caretakers.

Clinicians’ obligations to …

Current Issues In Rabies Prevention In The United States: Health Dilemmas, Public Coffers, Private Interests, Charles E. Rupprecht, Jean S. Smith, John Krebs, Michael Niezgoda, James E. Childs

Other Publications in Zoonotics and Wildlife Disease

Over the last 100 years, rabies in the United States has changed dramati~ally. More than 90% of all animal rabies cases reported annually to the CDC now occur in wildlife, whereas before 1960 the majority were in domestic animals. The principal rabies hosts today are wild carnivores and bats infected with several viral variants. Annual human deaths have fallen from more than a hundred at the turn of the century to one to two per year despite major outbreaks of animal rabies in several geographic areas. Modem day prophylaxis has proven nearly 100% successful; most human fatalities now occur in …

The Course Of Aggression In First-Grade Children With And Without Comorbid Anxious Symptoms, Nick Ialongo, Gail Edelsohn, Lisa Werthamer-Larsson, Lisa J. Crockett, Sheppard Kellam

Department of Psychology: Faculty Publications

We studied the course of aggressive behavior in an epidemiologically defined sample of first graders with and without comorbid anxious symptoms. Our primary purpose in doing so was to understand whether the stability of aggression in young children was attenuated or strengthened in the presence of comorbid anxiety. Previous studies of older children and adolescents had produced equivocal findings in this regard. Data on anxious symptoms were obtained through an interview of the children, whereas aggressive behavior was assessed through the use of a teacher interview and peer nominations. Assessments were performed in the fall and spring of first grade. …

Second-Order Conditioning Detects Unexpressed Morphine-Induced Salt Aversion, Rick A. Bevins, Timothy A. Delzer, Michael T. Bardo

Department of Psychology: Faculty Publications

Morphine failed to condition a salt taste aversion at a dose (15 mg/kg) sufficient to produce a robust aversion to a saccharin taste. Indeed, three different concentrations of salt (1%, 1.5%, and 2%) paired with the same morphine dose yielded no direct evidence for conditioned aversion. Yet, when a novel saccharin taste was paired in compound with the previously conditioned salt conditioned stimulus, we found evidence for a conditioning to the saccharin cue alone in three separate experiments. Control groups eliminated alternative accounts such as neophobia and differential exposure to morphine. Combined, these findings indicate that morphine conditioned a salt …

The Latency-Related Gene Of Bovine Herpesvirus 1 Encodes A Product Which Inhibits Cell Cycle Progression, L. M. Schang, Ashfaque Hossain, Clinton J. Jones

School of Veterinary and Biomedical Sciences: Faculty Publications

Bovine herpesvirus 1 (BHV-1) establishes a latent infection in the sensory ganglionic neurons of cattle. The exclusive viral RNA expressed in a latent infection is the latency-related (LR) RNA, suggesting that it regulates some aspect of a latent infection. During the course of a productive infection, alphaherpesviruses induce certain events which occur during cell cycle progression. Consequently, we hypothesized that a BHV-1 infection might induce events in neurons which occur during cell cycle progression. In agreement with this hypothesis, cyclin A was detected in neurons of trigeminal ganglia when rabbits were infected. Neuronal cell cycle progression or inappropriate expression of …

Longitudinal Adjustment Patterns Of Boys And Girls Experiencing Early, Middle, And Late Sexual Intercourse, C. Raymond Bingham, Lisa J. Crockett

Department of Psychology: Faculty Publications

This study examined the association between psychosocial development and the timing of first sexual intercourse in a sample of White, rural adolescents. Two theoretical models were tested. The first model, derived from problem behavior theory, proposed that earlier timing of first sexual intercourse is associated with longitudinal patterns of transition proneness and poor psychosocial adjustment. The second model, the stage termination model, proposed that early first sexual intercourse interferes with subsequent development, thereby resulting in negative developmental outcomes. problem behavior theory was supported. For both boys and girls, earlier timing of first sexual intercourse was associated with longitudinal patterns of …

Ultrasound Three- Dimensional Velocity Measurements By Feature Tracking, Gregory R. Bashford, Olaf T. Von Ramm

Biomedical Imaging and Biosignal Analysis Laboratory

This article describes a new angle-independent method suitable for three-dimensional (3-D) blood flow velocity measurement that tracks features of the ultrasonic speckle produced by a pulse echo system. In this method, a feature is identified and followed over time to detect motion. Other blood flow velocity measurement methods typically estimate velocity using one- (1-D) or two-dimensional (2-D) spatial and time information. Speckle decorrelation due to motion in the elevation dimension may hinder this estimate of the true 3-D blood flow velocity vector. Feature tracking is a 3-D method with the ability to measure the true blood velocity vector rather than …

Comments On The Distribution Of Botrychium Lunarioides (Ophioglossaceae) In Texas, W. C. Holmes, T. L. Morgan, Jeffrey R. Stevens, R. D. Gooch, J. R. Singhurst

Department of Psychology: Faculty Publications

Botrychium lunarioides (Michx.) Sw. (Ophioglossaceae) is now known to be widespread and abundant throughout the eastern portion of Texas. In 1996, Do, et al. reported ten additional county records in the central portion of the Post Oak Savannah of Texas, thereby extending the known distribution of the species up to 273 km to the west. Additional field studies during 1996 have yielded nineteen new county records for the species in Texas. These new reports are primarily from the Post Oak Savannah, Pineywoods, and Blackland Prairies of northeast Texas and from the southern portion of the Post Oak Savannah. The most …

Conditioned Stimulus Determinants Of Conditioned Response Form In Pavlovian Fear Conditioning, Stephen D. Kim, Steven Rivers, Rick A. Bevins, John J. B. Ayres

Department of Psychology: Faculty Publications

Four experiments using barpress conditioned suppression in rats found that tone evoked more freezing (immobility) than did light. Still, tone and light appeared to have similar conditioned value as assessed by suppression in Experiments 1, 2, and 3, and by blocking, second-order conditioning, and over-conditioning assays in Experiments 1, 2, and 3, respectively. Experiment 4 arranged for tone to evoke less suppression than light but more freezing. Results suggest that in fear conditioning, the nature of the conditioned stimulus affects the form of conditioned responding (strong vs. weak freezing). This conclusion extends one drawn by P. C. Holland (1977) on …

Identification Of A Brazil-Nut Allergen In Transgenic Soybeans, Julie A. Nordlee, Steve L. Taylor, Jeffrey A. Townsend, Laurie A. Thomas, Robert K. Bush

Department of Food Science and Technology: Faculty Publications

Background: The nutritional quality of soybeans (Glycine max) is compromised by a relative deficiency of methionine in the protein fraction of the seeds. To improve the nutritional quality, methionine-rich 2S albumin from the Brazil nut (Bertholletia excelsa) has been introduced into transgenic soybeans. Since the Brazil nut is a known allergenic food, we assessed the allergenicity of the 2S albumin. Methods: The ability of proteins in transgenic and nontransgenic soybeans, Brazil nuts, and purified 2S albumin to bind to IgE in serum from subjects allergic to Brazil nuts was determined by radioallergosorbent tests (four subjects) and …

Envy And Jealousy As Discrete Emotions: A Taxometric Analysis, Nick Haslam, Brian H. Bornstein

Department of Psychology: Faculty Publications

Envy and jealousy may differ in kind or only by degree. In a study of emotion episodes recalled by 291 subjects, two forms of taxometric analysis were used to test between categorical and dimensional models of the two emotions. The two emotions yielded strong convergent evidence of discreteness, and commonly co-occurred. However, although subjects rated their episode to contain similar levels of “envy” and “jealousy,” both terms were equally correlated with the presence of envy features and neither term was correlated substantially with the presence of jealousy features. Implications are drawn for the study of categorical distinctions between emotions, and …

Allergenic Foods, Susan L. Hefle, Julie A. Nordlee, Steve L. Taylor

Department of Food Science and Technology: Faculty Publications

Virtually all food allergens are proteins, although only a small percentage of the many proteins in foods are allergens. Any food that contains protein has the potential to cause allergic reactions in some individuals. However, a few foods or food groups are known to cause allergies on a more frequent basis than other foods. At a 1995 consultation on food allergies sponsored by the Food and Agriculture Organization, a group of international experts confirmed that peanuts, soybeans, crustacea, fish, cow’s milk, eggs, tree nuts, and wheat are the most common allergenic foods. These foods are responsible for more than 90% …

Comparison Of Gross Pathology, Histopathology, And Mycobacterial Culture For The Diagnosis Of Tuberculosis In Elk (Cervus Elaphus), Elizabeth B. Rohonczy, Arumuga V. Balachandran, Thomas W. Dukes, Janet B. Payeur, Jack C. Rhyan, Dennis A. Saari, Terry L. Whiting, Susan H. Wilson, Jerald L. Jarnagin

Michigan Bovine Tuberculosis Bibliography and Database

Using the isolation of Mycobacterium bovis as the reference standard, this study evaluated the sensitivity, specificity and kappa statistic of gross pathology (abattoir postmortem inspection), histopathology, and parallel or series combinations of the two for the diagnosis of tuberculosis in 430 elk and red deer. Two histopathology interpretations were evaluated: histopathology I, where the presence of lesions compatible with tuberculosis was considered positive, and histopathology II, where lesions compatible with tuberculosis or a select group of additional possible diagnoses were considered positive. In the 73 animals from which M. bovis was isolated, gross lesions of tuberculosis were most often in …

Timing Of First Sexual Intercourse: The Role Of Social Control, Social Learning, And Problem Behavior, Lisa J. Crockett, C. Raymond Bingham, Joanne S. Chopak, Judith R. Vicary

Department of Psychology: Faculty Publications

Prior research has pointed to several distinct processes that may affect the timing of first intercourse among adolescents. In the present study, the role of six hypothesized processes was assessed in a sample of 289 rural adolescent boys and girls. Results support the importance of family socialization and problem behavior for both sexes, the role of biological factors for boys, and the role of social control processes for girls. Two other hypothesized influences--social class and poor psychosocial adjustment--were not supported in either gender. These results indicate that multiple processes influence the timing of first intercourse; thus, they underscore the need …

A Cross-National Study On The Relations Among Prosocial Moral Reasoning, Gender Role Orientations, And Prosocial Behaviors, Gustavo Carlo, Silvia H. Koller, Nancy Eisenberg, Marcia S. Da Silva, Claudia B. Frohlich

Department of Psychology: Faculty Publications

This research examined the correlates of prosocial moral reasoning (PMR) in 2 studies. Study I investigated age, gender, and culture group differences in PMR in Brazilian children and adolescents (n = 265) and U.S. adolescents (n = 67). Relations between PMR and both prosocial behaviors and gender role orientations in Brazilian adolescents (n = 136) were explored in Study 2. Self-reflective, internalized reasoning was positively related, and hedonistic reasoning was negatively related, to peer ratings of prosocial behaviors. Femininity was associated with more self-reflective, internalized concerns and with less concerns regarding gaining others’ approval. In general, age …

Intentional Versus Unintentional Use Of Contingencies Between Perceptual Events, Kieth A. Carlson, John H. Flowers

Department of Psychology: Faculty Publications

In three experiments we studied human ability to use statistical contingencies between visual stimuli (flankers and targets) to improve performance in a letter–digit classification task. We compared the performance of explicitly informed subjects with that of subjects who were told nothing of the contingencies. Simultaneous presentation of flankers and targets (Experiment 1) produced evidence of unintentional contingency use by both informed and uninformed subjects. When stimuli on trial n predicted target stimuli on trial n + 1 (Experiment 2) there was no evidence of unintentional processes, but informed subjects showed strong evidence of using intentional prediction strategies. When flanker onset …

Evaluation Of Commercial Latex Reagents For Identification Of O157 And H7 Antigens Of Escherichia Coli, Evangeline G. Sowers, Joy G. Wells, Nancy A. Strockbine

Public Health Resources

Agglutination reactions obtained with three commercial latex reagents for detecting Escherichia coli O157 antigen (Oxoid Diagnostic Reagents, Hampshire, England; Pro-Lab Inc., Richmond Hill, Ontario, Canada; and Remel Microbiology Products, Lenexa, Kans.) and one for detecting H7 antigen (Remel) were compared with those obtained by standard serologic methods by using the Centers for Disease Control and Prevention (CDC) reference antisera for O157 and H7 antigens. For 159 strains of E. coli and related organisms, the Oxoid, Pro-Lab, and Remel O157 latex reagents each had a sensitivity and specificity of 100% compared with the CDC reference antiserum. For 106 strains of E. …

Cattle, Co-Wives, Children, And Calabashes: Material Context For Symbol Use Among The Il Chamus Of West-Central Kenya, Alan J. Osborn

Department of Anthropology: Faculty Publications

This paper examines systemic contexts for symbol use among the Maa-speaking Il Chamus in the Lake Baringo region of west-central Kenya. The systemic context for symbols and material culture consists of the environmental constraints and behavioral responses that characterize pastoralist life in East Africa. The author's interest in this problem developed in response to Ian Hodder’s work among the Il Chamus, Pokot, and Tugen in the Baringo District. Unlike Hodder, however, the author argues that symbols and their use in East Africa can be more productively explained from a materialist perspective. Specifically, it is proposed that symbols affixed to certain …

“Introduction” To Perspectives On Anxiety, Fear, And Panic, Debra Hope

Department of Psychology: Faculty Publications

In recent years the Nebraska Symposium on Motivation has returned explicitly to the theme of motivation. The 43d volume is no exception. In the spring of 1995, leading researchers and theorists came together in Lincoln, Nebraska, to offer their perspectives on anxiety, panic, and fear. Clearly, the theme of this year's symposium is closely tied to motivation.

The Effects Of Task Demands On The Equivalence Of Visual And Auditory Representations Of Periodic Numerical Data, Kimberly D. Turnage, Terri L. Bonebright, Dion C. Buhman, John H. Flowers

Department of Psychology: Faculty Publications

The equivalence of visual and auditory graphical displays was examined in two experiments. In Experiment 1, multidimensional scaling techniques were applied to paired comparison similarity judgments of both auditory and visual displays of simple periodic wave forms. In Experiment 2, a subset of perceptually similar pairs of wave forms was selected as the stimulus set for an AB–X discrimination task in both auditory and visual modalities. Results suggest much greater apparent visual– auditory equivalence for the similarity rating task than for the more difficult discrimination task, implying that one should consider the demands of the task when deciding whether auditory …
