Russian Parenting Styles And Family Processes: Linkages With Subtypes Of Victimization And Aggression, Craig H. Hart, David A. Nelson, Clyde C. Robinson, Susanne F. Olson, Mary Kay Mcneilly-Choque, Christin L. Porter, Trevor R. Mckee Jan 2000

Russian Parenting Styles And Family Processes: Linkages With Subtypes Of Victimization And Aggression, Craig H. Hart, David A. Nelson, Clyde C. Robinson, Susanne F. Olson, Mary Kay Mcneilly-Choque, Christin L. Porter, Trevor R. Mckee

Faculty Publications

Political changes in the former Soviet Union have allowed social scientists to explore a variety of family and child development issues that were closed to systematic investigation for many decades (Maddock, Hogan, Antonov, & Matskovsky, 1994). Prior Soviet psychological research focused on cognitive rather than socioemotional processes for political reasons (Kerig, 1996). Therefore, Western researchers had little opportunity to conduct research on children’s social development in the context of the family in the former Soviet Union.

Leveraging Analysis Operators In Incremental Generation, Deryle W. Lonsdale Jan 2000

Leveraging Analysis Operators In Incremental Generation, Deryle W. Lonsdale

Faculty Publications

This paper discusses the integration of an operator-based generation component with a similarly-designed natural-language comprehension system. It begins by sketching the cognitive theory and modeling system that frame both systems. A brief summary of the comprehension system and its characteristics follows, including the relevant operators. The generation system with its own operators and processing stages is then introduced. The degree to which these two systems exhibit shared functionality is then explored, and ongoing work is mentioned.

Jorgensen, T. Thomsen, M. Davidson, U. Goldbourt, S. Yaari, G. Cao, R. Cooper, R. Durazo-Arvizu, Z. Li, Y. Liao, D. Mcgee, T. E. Prewitt, C. Sempos

Faculty Publications

The authors examined the impact of smoking status on the relation between body mass index (weight (kg)/height (m)2) and mortality across a group of 15 diverse observational studies. The studies included a heterogeneous sample of national samples, cohort studies with mortality follow-up, and clinical trials. Consideration of the data according to natural strata resulted in the formation of 42 analytic cohorts. The authors examined survival through the end of follow-up for each study, as influenced by body mass index, age, and current smoking status at baseline, using a proportional hazards model to describe the relation between body mass index and …

Influence Of The Medium Length On High-Order Harmonic Generation, C. Delfin, C. Altucci, F. De Filippo, C. De Lisio, M. B. Gaarde, A. L'Huillier, L. Roos, C. G. Wahlström Nov 1999

Influence Of The Medium Length On High-Order Harmonic Generation, C. Delfin, C. Altucci, F. De Filippo, C. De Lisio, M. B. Gaarde, A. L'Huillier, L. Roos, C. G. Wahlström

Faculty Publications

We study high-order harmonic generation using a 110 fs Ti:sapphire laser loosely focused into a variable-length gas cell filled with neon or argon at 5 mbar pressure. The harmonic intensity is recorded as a function of the medium length, varying between 2 and 21 mm. Several cases are examined, the 17th and the 29th harmonic in argon, and the 29th and 51st harmonic in neon, at the same intensity 4 × 1014 W cm-2. We find that the length which maximizes the harmonic yield varies from 10 mm to more than 20 mm. We discuss the different effects affecting the …

Simulation And Density Functional Study Of A Simple Membrane Separating Two Restricted Primitive Model Electrolytes, Richard L. Rowley, Dezso Boda, Douglas Henderson, Stefan Sokolowski Nov 1999

Simulation And Density Functional Study Of A Simple Membrane Separating Two Restricted Primitive Model Electrolytes, Richard L. Rowley, Dezso Boda, Douglas Henderson, Stefan Sokolowski

Faculty Publications

A simple membrane, supporting charge densities on its inner and outer surfaces, is considered. In addition to the electrostatic potential, the membrane interacts with the surrounding fluid by a short range van der Waals-like potential. The fluid beyond the outer surface is a three-component restricted primitive electrolyte consisting of two cations and one anion. The membrane is impermeable to one of the cations so that the fluid in the membrane and beyond the inner surface is a two-component restricted primitive electrolyte. We use Monte Carlo simulations and density functional theory to study the density profiles of the electrolyte and the …

Regulation Of The Dolichol Pathway In Human Fibroblasts By The Endoplasmic Reticulum Unfolded Protein Response, William T. Doerrler, Mark A. Lehrman Nov 1999

Regulation Of The Dolichol Pathway In Human Fibroblasts By The Endoplasmic Reticulum Unfolded Protein Response, William T. Doerrler, Mark A. Lehrman

Faculty Publications

Accumulation of unfolded proteins within the endoplasmic reticulum (ER) of eukaryotic cells triggers the unfolded protein response (UPR), which activates transcription of several genes encoding ER chaperones and folding enzymes. This study reports that conversion of dolichol-linked Man2-5GIcNAc2 intermediates into mature Glc3Man9GlcNAc2 oligosaccharides in primary human adult dermal fibroblasts is also stimulated by the UPR. This stimulation was not evident in several immortal cell lines and did not require a cytoplasmic stress response. Inhibition of dolichol-linked Glc3Man9GlcNAc2 synthesis by glucose deprivation could be counteracted by the UPR, improving the transfer of Glc3Man9GlcNAc2 to asparagine residues on nascent polypeptides. Glycosidic processing …

Nutrient Cycling In The Water Column Of A Subtropical Seagrass Meadow, Susan Ziegler, Ronald Benner Nov 1999

Nutrient Cycling In The Water Column Of A Subtropical Seagrass Meadow, Susan Ziegler, Ronald Benner

Faculty Publications

The cycling of nutrients was studied over a 16 mo period to determine how processes occurring between the water column and benthos influenced nutrient dynamics in a Thalassia testudinum dominated seagrass meadow. Nutrient concentrations were low and ranged from below detection to 0.59 µM ammonium (NH4+), 0.04 to 0.29 µM nitrate plus nitrite (NO3- + NO2-), and below detection to 0.22 µM soluble reactive phosphate (SRP). Water column and benthic fluxes of NO3- + NO2- and SRP were usually below detection. The benthic fluxes of NH4+ …

Validity Of The Previous Day Physical Activity Recall (Pdpar) In Fifth-Grade Children, Stewart G. Trost, Dianne S. Ward, Ben Mcgraw, Russell R. Pate Nov 1999

Validity Of The Previous Day Physical Activity Recall (Pdpar) In Fifth-Grade Children, Stewart G. Trost, Dianne S. Ward, Ben Mcgraw, Russell R. Pate

Faculty Publications

This study evaluated the validity of the Previous Day Physical Activity Recall (PDPAR) self-report instrument in quantifying after-school physical activity behavior in fifth-grade children. Thirty-eight fifth-grade students (mean age, 10.8 ± 0.1; 52.6%; female; 26.3% African American) from two urban elementary schools completed the PDPAR after wearing a CSA WAM 7164 accelerometer for a day. The mean within-subject correlation between self-reported MET level and total counts for each 30-min block was 0.57 (95% C.I., 0.51-0.62). Self-reported mean MET level during the after-school period and the number of 30-min blocks with activity rated at > 6 METs were significantly correlated with the …

Accuracy Of Scatterometer-Derived Winds Using The Cramer-Rao Bound, David G. Long, Travis E. Oliphant Nov 1999

Accuracy Of Scatterometer-Derived Winds Using The Cramer-Rao Bound, David G. Long, Travis E. Oliphant

Faculty Publications

A wind scatterometer makes measurements of the normalized radar-backscatter coefficient O of the ocean surface. To retrieve the wind, a geophysical model function (GMF), which relates O to the near-surface wind, is used. The wind vector can be estimated using maximum-likelihood techniques from several O measurements made at different azimuth angles. The probability density of the measured O is assumed to be Gaussian with a variance that depends on the true O and therefore, depends on the wind through the GMF. With this model for wind estimation, the Cramer-Rao (C-R) bound is derived for wind estimation, and its implications for …

The optical transient of the faint gamma-ray burst GRB 990308 was detected by the QUEST camera on the Venezuelan 1 m Schmidt telescope starting 3.28 hr after the burst. Our photometry gives V= 18.32 ± 0.07, R = 18.14 ± 0.06, B = 18.65 ± 0.23, and R = 18.22 ± 0.05 for times ranging from 3.28 to 3.47 hr after the burst. The colors correspond to a spectral slope of close to fv ∝ v1/3. Within the standard synchrotron fireball model, this requires that the external medium be less dense than 104 cm-3, the electrons contain more than 20% …

High Crimes And Misdemeanors: Defining The Constitutional Limits On Presidential Impeachment, Frank O. Bowman Iii, Stephen L. Sepinuck Oct 1999

High Crimes And Misdemeanors: Defining The Constitutional Limits On Presidential Impeachment, Frank O. Bowman Iii, Stephen L. Sepinuck

Faculty Publications

This Article had its genesis in a statement by the authors submitted to the House Judiciary Committee during its proceedings regarding the impeachment of President Clinton. This final much expanded version appears after the conclusion of the Clinton impeachment proceedings in the Senate, and it is certainly informed by the course those proceedings took. Strictly speaking, however, this is not an article “about” the Clinton impeachment. Although this Article draws some conclusions from the treatment by the House and Senate of the fundamental allegations against President Clinton, it does not address in detail the specific facts underlying those allegations.

(Seven Principles For Good Practice In Legal Education): Principle 5: Good Practice Emphasizes Time On Task, R. Lawrence Dessem Oct 1999

(Seven Principles For Good Practice In Legal Education): Principle 5: Good Practice Emphasizes Time On Task, R. Lawrence Dessem

Faculty Publications

Time plus energy equals learning. Efficient time-management skills are critical for students and professors alike. Allocating realistic amounts of time means effective learning for students and effective teaching for faculty. How an institution defines time expectations for students, faculty, administrators, and other professional staff can establish the basis for high performance for all. The fifth principle for good practice in undergraduate education is almost a truism: good practice emphasizes time on task. In their original statement of the seven principles, Arthur W. Chickering and Zelda F. Gamson expressed this as a mathematical formula: “Time plus energy equals learning.” Time on …

Why In-House Live Client Clinics Won't Work In Romania: Confessions Of A Clinician Educator, Rodney J. Uphoff Oct 1999

Why In-House Live Client Clinics Won't Work In Romania: Confessions Of A Clinician Educator, Rodney J. Uphoff

Faculty Publications

Romanians eat our Big Macs, wolf down pizza slices at Pizza Hut, and guzzle Coca-Cola. They wear baseball caps, Nike clothing, and tennis shoes. They listen to American rap and pop music, see American movies with Romanian subtitles, and watch all of our old television shows. Romanians of all ages, but especially the young, hunger and thirst for all things Western, particularly from the United States. Doesn't it follow, then, that Romanian law schools ought to have - and, indeed, Romanian law professors would want - that symbol of an innovative, modern American law school curriculum: a live client clinical …

Faculty Publications

We present multicolor optical and two-frequency radio observations of the bright BeppoSAX event GRB 990510. Neither the well-sampled optical decay nor the radio observations are consistent with simple spherical afterglow models. The achromatic steepening in the optical band and the early decay of the radio afterglow, which both occur at t ∼ 1 day, are evidence for hydrodynamical evolution of the source and can be most easily interpreted by models in which the gamma-ray burst ejecta are collimated in a jet. Employing a simple jet model to explain the observations, we derive a jet opening angle of θ0 = 0.08(n/l …

Negotiated Development Denial Meets People's Court: Del Monte Dunes Brings New Wildcards To Exactions Law, Jonathan M. Davidson, Ronald H. Rosenberg, Michael C. Spata

Faculty Publications

The United States Supreme Court Answered "YES" to the $1.45 million over exaction question for 1999. In City of Monterey v. Del Monte Dunes at Monterey Ltd., a unanimous court extended the scope of compensatory takings review beyond land dedication conditions into the realm of regulatory denial. Justice Kennedy's opinion vitalized the "legitimate state interests" test from Agins v. City of Tiburon to sustain an inverse condemnation conclusion and damage award to the frustrated developer. A majority of the court also concurred that the trial court may delegate this takings conclusion to the jury under federal civil rights law. The …

Factitious Disorders And Trauma-Related Diagnoses, Daniel Brown, Alan Scheflin Oct 1999

Factitious Disorders And Trauma-Related Diagnoses, Daniel Brown, Alan Scheflin

Faculty Publications

The recent plethora of lawsuits involving allegations of iatrogenically implanted memories of satanic ritual abuse and other traumas has highlighted the existence of a unique group of psychiatric patients. Although these patients are often successful at deceiving therapists (and sometimes juries), the case studies in this special issue reveal the chronic nature of their propensity to invent traumatic identities and past histories. The core clinical features of affect dysregulation, somatization, and impaired object relations, together with frequent histories of alcohol and substance abuse, parallel the psychiatric co-morbidity frequently found in genuine trauma victims. These case studies also point to early …

Toward The Development Of A Pursuit Decision Calculus: Pursuit Benefits Versus Pursuit Cost, Thomas J. Madden, Geoffrey P. Alpert Oct 1999

Toward The Development Of A Pursuit Decision Calculus: Pursuit Benefits Versus Pursuit Cost, Thomas J. Madden, Geoffrey P. Alpert

Faculty Publications

To make unbiased decisions about whether to pursue a fleeing vehicle, officers must understand both the costs and the potential benefits of a pursuit. This manuscript describes an approach that identifies and assesses the impact of pursuit characteristics on pursuit costs. Data from official pursuit forms generated by officers in the Miami-Dade police department were used as a basis of the study. Log-linear models were used to identify direct and interactive effects of the pursuit characteristics. Upon finding significant effects, odds ratios were calculated. The findings indicate that there are certain pursuit characteristics, including number of units and speed, that …

Evaluation Of The Use Of Optical Fiber Thermometers For Thermal Control Of The Quench Module Insert, Matthew R. Jones, Jeffery T. Farmer, Shawn P. Breeding Sep 1999

Evaluation Of The Use Of Optical Fiber Thermometers For Thermal Control Of The Quench Module Insert, Matthew R. Jones, Jeffery T. Farmer, Shawn P. Breeding

Faculty Publications

Issues regarding the use of optical fiber thermometers to control heater settings in a microgravity vacuum furnace are addressed. It is desirable to use these probes in environments such as the International Space Station, because they can be operated without re-calibration for extended periods. However, the analysis presented in this paper shows that temperature readings obtained using optical fiber thermometers can be corrupted by emissions from the fiber when extended portions of the probe are exposed to elevated temperatures.

The Spectrum Of Grb 930131 ("Superbowl Burst") From 20 Kev To 200 Mev, Volker Bromm, Bradley E. Schaefer Aug 1999

The Spectrum Of Grb 930131 ("Superbowl Burst") From 20 Kev To 200 Mev, Volker Bromm, Bradley E. Schaefer

Faculty Publications

We have constructed a broadband spectrum for GRB 930131 (the "Superbowl Burst"), ranging from 20 keV to 200 MeV, by combining spectral information from the Gamma Ray Observatory's BATSE, COMPTEL, and EGRET instruments. We present general methods for combining spectra from different time intervals obtained by the same instrument as well as for combining spectra from the same time interval taken by different instruments. The resulting spectrum is remarkably flat (in vFv-space) up to high energies. We find that the spectral shape can be successfully fitted by the shocked synchrotron emission model of Tavani. We present evidence that the flatness …

Combining Cross-Validation And Confidence To Measure Fitness, Tony R. Martinez, D. Randall Wilson Jul 1999

Combining Cross-Validation And Confidence To Measure Fitness, Tony R. Martinez, D. Randall Wilson

Faculty Publications

Neural network and machine learning algorithms often have parameters that must be tuned for good performance on a particular task. Leave-one-out cross-validation (LCV) accuracy is often used to measure the fitness of a set of parameter values. However, small changes in parameters often have no effect on LCV accuracy. Many learning algorithms can measure the confidence of a classification decision, but often confidence alone is an inappropriate measure of fitness. This paper proposes a combined measure of Cross- Validation and Confidence (CVC) for obtaining a continuous measure of fitness for sets of parameters in learning algorithms. This paper also proposes …

Cross Validation And Mlp Architecture Selection, Timothy L. Andersen, Tony R. Martinez Jul 1999

Cross Validation And Mlp Architecture Selection, Timothy L. Andersen, Tony R. Martinez

Faculty Publications

The performance of cross validation (CV) based MLP architecture selection is examined using 14 real world problem domains. When testing many different network architectures the results show that CV is only slightly more likely than random to select the optimal network architecture, and that the strategy of using the simplest available network architecture performs better than CV in this case. Experimental evidence suggests several reasons for the poor performance of CV. In addition, three general strategies which lead to significant increase in the performance of CV are proposed. While this paper focuses on using CV to select the optimal MLP …

Seeking Causal Explanations In Social Epidemiology, Jay S. Kaufman, Richard S. Cooper Jul 1999

Seeking Causal Explanations In Social Epidemiology, Jay S. Kaufman, Richard S. Cooper

Faculty Publications

Social factors are associated with a wide variety of health outcomes. Social epidemiology has successfully used the traditional methods of surveillance and description to establish consistent relations between social factors and health status. Epidemiology as an etiologic science, however, has been largely ineffective in moving toward causal explanations for these observed patterns. Using the counterfactual approach to causal inference, the authors describe several fundamental problems that often arise when researchers seek to infer explanatory mechanisms from data on social factors. Contrasts that form standard causal effect estimates require implicit unobserved (counterfactual) quantities, because observational data provide only one exposure state …
