Spectral Measures And Perceptual Ratings Of Hypokinetic Dysarthria, Christopher Dromey

Faculty Publications

Ten individuals with Parkinson disease (PD) and hypokinetic dysarthria were compared with age-matched neurologically normal (NN) speakers on acoustic measures from speaking and vowel phonation tasks as well as on perceptual ratings of connected speech. Listeners identified differences between the groups when asked to judge the severity of vocal and articulatory impairment during reading. Several conventional acoustic measures failed to differentiate speakers with PD from NN speakers. However, measures of the shape (statistical moments) of the long term average spectrum (LTAS) revealed statistically significant differences between the groups across vowel phonation, reading and monologue tasks. The ease of computation of …

Parenting And Adult Development: Contexts, Processes, And Products Of Intergenerational Relationships, Rob Palkovitz, Loren D. Marks, David W. Appleby, Erin K. Holmes

Faculty Publications

For the past 50 years, parenthood has been discussed in social science literature as a context of adult development. Theories, anecdotes, and the opinions of laypersons are nearly unanimous: People who become parents and are involved in the raising of children are transformed and follow a different developmental trajectory from people who do not engage in parenting roles. Erickson (1950) suggested that positive adult development reflects care for the next generation, or "generativity," and that parenthood is "the first, and for many, the prime generative encounter" (Erickson, 1964, p. 130). More recently, parenthood has been described as a necessary but …

“Rocky Mountain Entrepreneur: Robert Campbell As A Fur Trade Capitalist.”, Jay H. Buckley

Faculty Publications

Between 1825 and 1835 Robert Campbell emerged as a fur trade entrepreneur. Campbell served as clerk for Ashley-Smith, as brigade leader for Smith, Jackson, and Sublette, and supplier and financier for the Rocky Mountain Fur Company. Campbell quickly became a dominant figure in the American fur trade. In addition to leading fur brigades, Campbell and his partner William Sublette built several trading posts (most notably Fort Laramie), supplied the annual rendezvous, and challenged John Jacob Astor's American Fur Company on the Missouri River. Through it all, Campbell's business acumen helped him pursue economic opportunities that paved the way for future …

Using Gis For Forest Recreation Planning On The Longleaf Ridge Special Area Of The Angelina National Forest, East Texas, I-Kuai Hung

Faculty Publications

Longleaf Ridge Special Area (LRSA) located in the Angelina National Forest is the westernmost example of a longleaf pine savanna community. Ecologically, the area is one of the most diverse communities in Texas. Due to its size, abundant natural and historical resources, numerous outdoor recreation opportunities exist. In this study, GIS was used to develop a forest recreation concept plan on LRSA. Most of the geospatial data came from public entities. Information for demand analysis on forest recreation was obtained from the 2000 National Survey on Recreation and the Environment database. U.S. Forest Service recreation fee envelope data were analyzed …

Predicting The Readability Of Transparent Text, Lauren F. V. Scharff, Albert J. Ahumada Jr.

Faculty Publications

Will a simple global masking model based on image detection be successful at predicting the readability of transparent text? Text readability was measured for two types of transparent text: additive (as occurs in head-up displays) and multiplicative (which occurs in see-through liquid crystal display virtual reality displays). Text contrast and background texture were manipulated. Data from two previous experiments were also included (one using very low contrasts on plain backgrounds, and the other using higher-contrast opaque text on both plain and textured backgrounds). All variables influenced readability in at least an interactive manner. When there were background textures, the global …

Association Of Swim Distance And Age With Body Composition In Adult Female Swimmers, Georgianna Tuuri, Mark Loftin, Jeffrey Oescher

Faculty Publications

Purpose: The purpose of this investigation was to examine the relationship between average weekly swimming distance and age with body composition in adult female endurance swimmers. Methods: Thirty-five women, aged 21-73 yr. volunteered to participate. Weekly swimming distance was determined from a self-reported exercise log. Body composition was estimated by dual-energy x-ray absorptiometry (DXA), waist circumference, abdominal sagittal diameter, and skinfold thickness measures. Associations between swimming distance and age with body composition were examined using regression analysis. Results: Swimming distance had shared variances as follows: 23% with percent body fat, 26% with waist circumference, 20% with abdominal sagittal diameter, and …

Urinary Excretion Of Dithiocarbamates And Selfreported Cruciferous Vegetable Intake: Application Of The ‘Method Of Triads’ To A Foodspecific Biomarker, Jay H. Fowke, James R. Hébert, Jed W. Fahey

Faculty Publications

Objective: Greater intake of Cruciferous vegetables (e.g. broccoli) may prevent cancer at several sites. Urinary excretion of isothiocyanate conjugates (dithiocarbamates, DTC) provides a specific biomarker of Cruciferous vegetable consumption suitable for epidemiological investigations. However, no gold-standard referent is available for evaluating urinary DTC levels as an estimator of Cruciferous vegetable consumption. We compared urinary DTC levels to intake as measured by two selfreported dietary assessment techniques. Design: Cruciferous vegetable consumption was measured before and after a behavioural dietary intervention using multiple 24-hour recalls (24HR), a foodcounting questionnaire (VFQ) and urinary DTC excretion levels. Analysis included a structural equation approach (Method …

Interrelationships Among Landscapes, Ndvi, And Stream Water Quality In The Us Central Plains, Jerry A. Griffith, Edward A. Martinko, Jerry L. Whistler, Kevin P. Price

Faculty Publications

During late spring through summer of 1994 and 1995, 290 randomly selected stream sites in Nebraska, Kansas, and Missouri were sampled once for several parameters including conductivity, turbidity, total phosphorus, nitrate-nitrite nitrogen, the index of biotic integrity, and a habitat index. Based on landscape data from watersheds that were delineated for each sampling location, interrelationships were examined between these water quality parameters and land use/land cover, the normalized difference vegetation index (NDVI), and vegetation phenological metrics derived from the NDVI. Statistically significant relationships were found between NDVI values and the derived metrics with the stream condition parameters (r values to …

Brain Potentials Elicited By Prose-Embedded Linguistic Anomalies, Mark D. Allen, Kayo Inoue, Judith Mclaughlin, Lee Osterhout

Faculty Publications

Linguistic theories distinguish between syntax (sentence form) and semantics (sentence meaning). Correspondingly, recent studies have shown that syntactic and semantic anomalies elicit distinct changes in the event-related brain potential (ERP). However, these results have been obtained with highly artificial methodologies and have not yet been generalized to more natural reading conditions. Here, we recorded ERPs while subjects read a naturalistic prose passage. The subjects either read for comprehension with no other task being assigned or read for comprehension and made acceptability judgments after each sentence. Consistent with prior work and regardless of the subjects’ assigned task, syntactic anomalies elicited a …

Relational And Physical Victimization Within Friendships: Nobody Told Me There'd Be Friends Like These, Nicki R. Crick, David A. Nelson

Faculty Publications

In past research, relational and physical forms of peer victimization have been identified that have been shown to be significantly associated with social–psychological maladjustment. These forms of victimization, although studied primarily within the group peer context, also occur within dyadic relationships such as friendships. Gender differences in friend victimization and the association between friend victimization and children's social–psychological adjustment were examined. Results showed that boys were more physically victimized by their friends than were girls. Girls were more relationally than physically victimized by their friends. Friend victimization was related to adjustment difficulties for both boys and girls; however, friend physical …

Nitrogen Loading Into An Urban Estuary: Lake Pontchartrain (Louisiana, U.S.A.), R. Eugene Turner, Q. Dortch, Dubravko Justic, Erick M. Swenson

Faculty Publications

We constructed a nitrogen loading budget for the Lake Pontchartrain watershed located north of New Orleans, Louisiana (U.S.A.). Water quality measurements, discharge estimates, and literature values were used to establish the annual and seasonal variations in loading rates for total nitrogen and nitrate. The relatively stable annual loadings (million kg N) are about 10× that of the pre-settlement nitrogen loading, and come from atmosphere (1.3), the watershed (7.8), pumped urban runoff from New Orleans (1.0), and leakage through the Bonnet Carré flood control structure (0.5–0.9). Relatively minor additional amounts come from nitrogen fixation in the Lake. Occasional openings of the …

Book Review: Law And Religion: Current Legal Issues 2001 - Volume 4, S. I. Strong

Faculty Publications

As volume four of Current Legal Issues demonstrates, commentary on the interplay between law and religion in the UK is growing, although the subject still attracts nowhere near the level of attention it does in other countries. The newest addition to the literature constitutes a welcome advance to lawyers working or interested in the field. For example, many existing collections of essays on law and religion focus primarily on sociological issues. This compilation, on the other hand, contains many essays that stress truly legal dilemmas, although sociological, philosophical and other approaches to the question are still well represented among the …

Activity Patterns And Correlates Among Youth: Differences By Weight Status, Wendell C. Taylor, James F. Sallis, Marsha Dowda, Patty S. Freedson, Karen Eason, Russell R. Pate

Faculty Publications

The purposes of the study were to assess differences in physical activity levels and correlates of physical activity among overweight (‡ 85th percentile of body mass index for their sex and age) and non-overweight (< 85th percentile) youth. The sample included 509 seventh through twelfth graders. Activity was measured by a 7-day, 46-item activity checklist. Overweight girls were more sedentary than non-overweight girls (p<.03), and non-overweight girls engaged in more vigorous physical activity than overweight girls (p<.03). For boys, there were no significant differences in activity. The regression analyses for vigorous activity yielded the largest total R²'s (R²=.049 for overweight and R²=.27 for non-overweight.) The significant factor for overweight youth was greater athletic coordination (p<.01). For non-overweight youth, the significant factors were greater family support (p<.05), greater peer support (p<.001), fewer barriers (p<.03), and greater athletic coordination (p<.01). Correlates of physical activity vary by weight status of young people.

Associations Between Cardiorespiratory Fitness And C-Reactive Protein In Men, Timothy S. Church, Carolyn E. Barlow, Conrad P. Earnest, James B. Kampert, Elisa L. Priest, Steven N. Blair

Faculty Publications

Objective - This study examined the association between cardiorespiratory fitness and C-reactive protein (CRP), with adjustment for weight and within weight categories.

Methods and Results - We calculated median and adjusted geometric mean CRP levels, percentages of individuals with an elevated CRP (≥2.00 mg/L), and odds ratios of elevated CRP across 5 levels of cardiorespiratory fitness for 722 men. CRP values were adjusted for age, body mass index, vitamin use, statin medication use, aspirin use, the presence of inflammatory disease, cardiovascular disease, and diabetes, and smoking habit. We found an inverse association of CRP across fitness levels (P for …

Measurement Of Diffractive Production Of D*±(2010) Mesons In Deep-Inelastic Scattering At Hera, S. Chekanov, D. Krakauer, S. Magill, B. Musgrave, J. Repond, R. Yoshida, Margarita C. K. Mattingly, P. Antonioli, G. Bari, M. Basile, L. Bellagamba, D. Boscherini, A. Bruni, G. Bruni, G. Cara Romeo, L. Cifarelli, F. Cindolo, A. Contin, M. Corradi, S. De Pasquale, P. Giusti, G. Iacobucci, A. Margotti, R. Nania, F. Palmonari, A. Pesci, G. Sartorelli, A. Zichichi, G. Aghuzumtsyan, D. Bartsch, I. Brock

Faculty Publications

Diffractive production of D*±(2010) mesons in deep inelastic scattering has been measured with the ZEUS detector at HERA using an integrated luminosity of 44.3 pb-1. Diffractive charm production is identified by the presence of a large rapidity gap in the final state of events in which a D*±(2010) meson is reconstructed in the decay channel D*+ → (D0 → K-π+)πs+ (+ charge conjugate). Differential cross sections when compared with theoretical predictions indicate the importance of gluons in such diffractive interactions. © 2002 Elsevier Science B.V. All rights reserved.

Unwarranted Variations In The Quality Of Health Care: Can The Law Help Medicine Provide A Remedy/Remedies?, Philip G. Peters Jr., John E. Wennberg M.D.

Faculty Publications

This article reviews the essential findings of studies of variations in quality of care according to three categories of care: effective care, preference-sensitive care, and supply-sensitive care. It argues that malpractice liability and informed consent laws should be based on standards of practice that are appropriate to each category of care. In the case of effective care, the legal standard should be that virtually all of those in need should receive the treatment, whether or not it is currently customary to provide it. In the case of preference-sensitive care, the law should recognize the failure of the doctrine of informed …

Fluid Dynamics Of Flapping Aquatic Flight In The Bird Wrasse: Three-Dimensional Unsteady Computations With Fin Deformation, Ravi Ramamurti, William C. Sandberg, Rainald Lӧhner, Jeffrey A. Walker Phd, Mark W. Westneat

Faculty Publications

Many fishes that swim with the paired pectoral fins use fin-stroke parameters that produce thrust force from lift in a mechanism of underwater flight. These locomotor mechanisms are of interest to behavioral biologists, biomechanics researchers and engineers. In the. present study, we performed the first three-dimensional unsteady computations of fish swimming with oscillating and deforming fins. The objective of these computations was to investigate the fluid dynamics of force production associated with the flapping aquatic flight of the bird wrasse Gomphosus varius. For this computational work, we used the geometry of the wrasse and its pectoral fin, and previously measured …

Mammalian Retroelements, Prescott L. Deininger, Mark A. Batzer

Faculty Publications

The eukaryotic genome has undergone a series of epidemics of amplification of mobile elements that have resulted in most eukaryotic genomes containing much more of this 'junk' DNA than actual coding DNA. The majority of these elements utilize an RNA intermediate and are termed retroelements. Most of these retroelements appear to amplify in evolutionary waves that insert in the genome and then gradually diverge. In humans, almost half of the genome is recognizably derived from retroelements, with the two elements that are currently actively amplifying, L1 and Alu, making up about 25% of the genome and contributing extensively to disease. …

Identification Of A Streptolysin S-Associated Gene Cluster And Its Role In The Pathogenesis Of Streptococcus Iniae Disease, Jeffrey D. Fuller, Alvin C. Camus, Carla L. Duncan, Victor Nizet, Darrin J. Bast, Ronald L. Thune, Donald E. Low, Joyce C.S. De Azavedo

Faculty Publications

Streptococcus iniae causes meningoencephalitis and death in cultured fish species and soft-tissue infection in humans. We recently reported that S. iniae is responsible for local tissue necrosis and bacteremia in a murine subcutaneous infection model. The ability to cause bacteremia in this model is associated with a genetic profile unique to strains responsible for disease in fish and humans (J. D. Fuller, D. J. Bast, V. Nizet, D. E. Low, and J. C. S. de Azavedo, Infect. Immun. 69:1994-2000, 2001). S. iniae produces a cytolysin that confers a hemolytic phenotype on blood agar media. In this study, we characterized the …

Empirical Evidence And Malpractice Litigation, Philip G. Peters Jr.

Faculty Publications

Critics of medical malpractice litigation believe that expert testimony is often anecdotal and biased. To remedy this problem, several have recently suggested that attorneys should provide and courts should seek reliable empirical evidence of actual clinical norms. Their suggestion should be welcomed. If our expectations are realistic and the design pitfalls are avoided, greater use of use of empirical research will improve the fairness of malpractice adjudication. At least in theory, it could be useful in both the "easy" cases (where it reveals that a consensus standard of care exists) and also some of the harder cases (where clinical practices …
