Contextual Interference Effects In The Acquisition And Retention Of Motor Tasks By Individuals With Mild Mental Handicaps, William J. Vincent, Mary A. Painter, Kathleen B. Inman

Faculty Publications

The effects of contextual interference on motor skill acquisition and retention were examined in 24 subjects (mean age 13.9 years) with mild mental retardation and 24 chronologically age-matched subjects (mean age 13.11 years) with no disabilities. Subjects from each group were assigned randomly to either a blocked or a random practice schedule. All subjects performed 15 practice trials for each of three different beanbag throwing tasks, 45 trials total. Following a 10-min filled retention interval, 2 trials of each throw (6 total) were performed in a random order by all subjects. Accuracy scores were measured as absolute error from the …

Spiders: A New User Interface For Rotation And Visualization Of N-Dimensional Point Sets, William A. Barrett, Kirk L. Duffin

Comparison Of The S Genes And The Biological Properties Of Respiratory And Enteropathogenic Bovine Coronaviruses, X. Zhang, W. Herbst, K. G. Kousoulas, J. Storz

Faculty Publications

The nucleotide sequence of the S gene of the bovine respiratory coronavirus (BRCV) strain G95, which was isolated from nasal swabs of a calf suffering from respiratory disorders, was determined and compared with the S gene of the enteropathogenic bovine coronavirus (BECV) strain LY138. Sequence analysis revealed 98.7% nucleotide and 98.3% deduced amino acid identities between the S genes of BRCV-G95 and BECV-LY138 without any deletions or insertions. Nucleotide substitutions were distributed randomly throughout the gene. Five monoclonal antibodies specific for the S protein distinguished BRCV-G95 from BECV-L9, but failed to differentiate it from BECV-LY138 in Western blots under denatured …

Stature Change In Prehistoric Maya Of The Southern Lowlands, Marie E. Danforth

Faculty Publications

Since the 1950s, a decline in stature has been offered as evidence of increasing nutritional stress in prehistoric Maya populations, particularly during the Late Classic collapse. A review of the extant skeletal data, however, reveals very inconsistent support for such a decline. The primary explanation for the variation may reside in the small number of skeletal series that have representatives of more than one time period. Other possible explanations include methodological problems associated with stature reconstruction, reliability in sex determination, and variation in health response according to site size and location.

The Structure And Dynamics Of The Cs2 Molecular Ion, Karl Sohlberg, Chan Yibai

Faculty Publications

Several common elementary methods of computing molecular properties, prerequisite to molecular dynamics studies, are tested for their validity for CS+2. Judged sufficiently accurate, these methods are then used to aid in investigating the collisionally activated dissociation of CS+2 upon impact with xenon. Rice–Ramsperger–Kassel–Marcus (RRKM) unimolecular decay rate calculations are presented and compared to experimental studies employing collisional activation. RRKM theory is shown to reproduce the experimental results for collision energies near threshold. When corrected for vibrational anharmonicity, the RRKM calculation shows agreement with the experimental results over a slightly wider range of energies. A discussion is given on the applicability …

The Effects Of Gender On Career Decision Problems In Young Adults, Jeffry H. Larson, Mark Butler, Stephan Wilson, Nilufer Medora, Scot Allgood

Faculty Publications

The authors investigated gender differences in psychological problems in the career decision-making (CDM) process of young adults. Specifically, problems with decision anxiety, life-goal awareness, luck-fate orientation, authority orientation, and secondary gain motivation were investigated. Methodology involved administering the Career Decision Diagnostics Assessment (CDDA) instrument to 1,006 college students from four universities. Results indicated no gender differences in global levels of problems in CDM. Women reported more problems with life-goal awareness and authority orientation than did men. Men reported more problems with secondary gain motivations than did women. The results are discussed in terms of implications for gender-differentiated career counseling.

Thomas Hobbes's "A Discourse Of Laws", Noel B. Reynolds

Faculty Publications

The recent discovery that an anonymously published 1620 essay was an early writing of Thomas Hobbes invites investigation of his early thinking. Hobbes relied on mostly classical sources to advance a basically conventionalist theory of law and to anticipate twentieth century analyses of the principles of rule of law such as that made famous by F. A. Hayek.

Global Arrest Of Translation During Invertebrate Quiescence, Gretchen E. Hofmann, Steven C. Hand

Faculty Publications

Comparing the translational capacities of cell-free systems from aerobically developing embryos of the brine shrimp Artemia franciscana vs. quiescent embryos has revealed a global arrest of protein synthesis. Incorporation rates of [3H]leucine by lysates from 4-h anoxic embryos were 8% of those from aerobic (control) embryos, when assayed at the respective pH values measured for each treatment in vivo. Exposure of embryos to 4 h of aerobic acidosis (elevated CO2 in the presence of oxygen) suppressed protein synthesis to 3% of control values. These latter two experimental treatments promote developmental arrest of Artemia embryos and, concomitantly, cause acute declines in …

Double Jeopardy Issues In The Financial Sector; Outside Counsel, Richard L. Stone, Jay Facciolo

Faculty Publications

(Excerpt)

Double jeopardy issues arise regularly in the financial, banking and commodities industries where both civil and criminal statutes and penalties are used in successive prosecutions by federal and state governments to sanction the same conduct.

Recent Supreme Court and federal court decisions have established new standards for determining when civil fines and other civil penalties constitute “punishment” for purposes of the double jeopardy clause of the Fifth Amendment.

These decisions indicate that where a civil penalty imposed by a federal or state actor bears no “rational relation” to any actual damages caused, the penalty will be characterized as punishment …

Performance Analysis Of Antennas For Hand-Held Transceivers Using Fdtd, Michael A. Jensen, Yahya Rahmat-Samii

Faculty Publications

The design of antennas for hand-held communications devices depends on the implementation of simulation tools that can accurately model general topologies. The paper presents the analysis of small antennas mounted on hand-held transceivers using the finite-difference time-domain (FDTD) method. The key features of the FDTD implementation are discussed, with particular emphasis placed upon modeling of the source region. The technique is used to predict the gain patterns and broadband input impedance behavior of monopole, planar inverted F, and loop antenna elements mounted on the handset. Effects of the conducting handset chassis, the plastic casing around the device, and lumped elements …

Characterization Of The Near-Interface Region Of Chemical Vapor Deposited Diamond Films On Silicon By Backscatter Kikuchi Diffraction, Brent L. Adams, K. Kunze, S. Geier, R. Hessmer, B. Rauschembach, M. Schreck, B. Stritzker

Bollmeier is greatly appreciated. The lattice orientations near the interface of chemical vapor deposited diamond films on Si(001) have been studied by orientation imaging microscopy. This technique is based on the automated analysis of electron backscatter Kikuchi diffraction patterns. The electron beamhas been scanned in discrete steps over the reverse side of the diamond film after having removed the substrate. The obtained data have allowed us to determine the texture and to visualize quantitatively the …

The Asymptotic Structure Of Transient Elastodynamic Fields At The Tip Of A Stationary Crack, Xiaomin Deng

Faculty Publications

The asymptotic structure of the transient elastodynamic near-tip fields around a stationary crack is investigated for all three fracture modes. The transient fields are obtained as the sum of their quasi-static counterparts and corresponding transient correction terms, in terms of variable-separable expansions. By allowing the coefficients of terms in the quasi-static expansion to deviate from their quasi-static restrictions, the correction terms are shown to be the particular solutions of a set of first order (for mixed mode I and II) or second order (for mode III) ordinary differential equations with constant coefficients and non-homogeneous terms involving only sine and cosine …

A Functional Architecture For Automated Highway Traffic Planning, H.-S. Jacob Tsao

Faculty Publications

In a fully automated Automated Highway System (AHS), the roadside control system and the vehicles themselves are responsible for moving the large number of vehicles safely and efficiently. Therefore, the task of operating an AHS is drastically different from and much more complex than its conventional counterpart. Resulting from a large number of design options, there exist many possible ways to operate an AHS. Each of these possible operating scenarios will support a different set of functions. A crucial task in AHS R&D is to evaluate and compare these potentially large number of different AHS operating scenarios with respect to …

Providing An Escape For Inner-City Children: Creating A Federal Remedy For Educational Ills Of Poor Urban Schools, Amy J. Schmitz

Faculty Publications

Children in impoverished, urban areas attend dangerous and decrepit schools, where they receive low quality education which fails to prepare them for meaningful participation in the community. Many states, however, provide no legislative or judicial remedy for these children, who desperately need vocational and educational skills to enable them to escape from the deprivation of their urban landscape. Meanwhile, federal officials speak

Justice Defined - It Takes More Than A Single Opinion To Understand How Legal Reasoning And Personal Experience Shape A 24-Year Career, Richard C. Reuben

Faculty Publications

With his retirement in June after participating in more than 800 cases - including his career-identifying 7-2 opinion in Roe v. Wade legalizing abortion - the definition of Harry Blackmun's tenure lies in the seeming contradiction of commitment and flexibility. Along with a steadfast defense of the right to abortion in Roe, 410 U.S. 113 (1973), and successive cases, Blackmun's significance was in the power of his vote. Often overlooked in the public's emphasis on Roe is an appreciation of Blackmun's reflective, methodical, if not occasionally pointed, jurisprudence.

The Answering Machine Generation - Who Are They And What Problem Do They Pose For Survey Research, Robert W. Oldendick, Michael W. Link

Faculty Publications

Increased incidence of telephone answering machines and the use of such devices to screen calls pose a potential threat to the representativeness of samples in telephone surveys. Using data from nine statewide surveys, this analysis examines the extent to which answering machines are used to screen calls and the demographic characteristics associated with answering machine use and call screening. Results show that at most two to three percent of households use answering machines to screen calls, and that such screening is more likely to take place in households with higher family incomes, outside rural areas, and which include individuals who …

Aging And Exercise: A Health Perspective, Joanna L. Bokovoy, Steven N. Blair

Faculty Publications

Habitual exercise provides protection against fatal coronary heart disease, extends longevity, and enhances quality of life. National surveys show less physical activity in older men and women compared with middle-aged and younger persons; older women are particularly sedentary. Although there are still few longitudinal studies on exercise and physical activity in older individuals, the data support a positive relationship between physical activity and health function in older individuals. The data further show that with regular physical activity, health and fitness are maintained or even increased over time in older individuals. Studies on physical activity requirements for beneficial health effects in …

Mesostructure Of Photoluminescent Porous Silicon, David D. Allred, F. Ruiz, C. Vázquez-López, Jesus González-Hernández, G. Romero-Paredes, R. Peña-Sierra, G. Torres-Delgado

Faculty Publications

Scanning electron microscopy, atomic force microscopy, and Raman spectroscopy were used to characterize the microstructure of photoluminescent porous silicon (PS) layers formed by the anodic etching (HF:H2O:ethanol), at various current densities, of p-type (100) silicon wafers possessing resitivity in the range 1-2 Ω cm. Existing models for the origin of luminescence in PS are not supported by our observations. Cross-sectional as well as surface atomic force micrographs show the material to be clumpy rather than columnar; rodlike structures are not observed down to a scale of 40 nm. A three-dimensional model of the mesostructure of porous silicon is discussed. Room-temperature …
