Field-Scale Estimation Of Volumetric Water Content Using Ground-Penetrating Radar Ground Wave Techniques, Katherine R. Grote, Susan Sharpless Hubbard, Yoram N. Rubin Nov 2003

Field-Scale Estimation Of Volumetric Water Content Using Ground-Penetrating Radar Ground Wave Techniques, Katherine R. Grote, Susan Sharpless Hubbard, Yoram N. Rubin

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

Ground-penetrating radar (GPR) ground wave techniques were applied to estimate soil water content in the uppermost ∼10 cm of a 3 acre California vineyard several times over 1 year. We collected densely spaced GPR travel time measurements using 900 and 450 MHz antennas and analyzed these data to estimate water content. The spatial distribution of water content across the vineyard did not change significantly with time, although the absolute water content values varied seasonally and with irrigation. The GPR estimates of water content were compared to gravimetric water content, time domain reflectometry, and soil texture measurements. The comparisons of GPR-derived …

Oci-Based Group Communication Support In Corba, Dongman Lee, Dukyun Nam, Hee Yong Youn, Chansu Yu Nov 2003

Oci-Based Group Communication Support In Corba, Dongman Lee, Dukyun Nam, Hee Yong Youn, Chansu Yu

Electrical and Computer Engineering Faculty Publications

Group communication is a useful mechanism guaranteeing consistency among replicated objects. The existing approaches do not allow transparent plug-in of group communication protocols into CORBA. They either require modification of CORBA or OS, or provide no room for incorporating group communication transport protocols into CORBA. We thus propose a generic group communication framework that allows transparent plug-in of various group communication protocols with no modification of existing CORBA. We extend the open communications interface (OCI) to support interoperability, reusability of existing group communication, and independency on ORB and OS. We also define the group communication inter-ORB protocol (GCIOP) as a …

Sec Enforcement Heuristics: An Empirical Inquiry, Randall Thomas, James D. Cox Nov 2003

Sec Enforcement Heuristics: An Empirical Inquiry, Randall Thomas, James D. Cox

Vanderbilt Law School Faculty Publications

This Article examines the overlap between SEC securities enforcement actions and private securities fraud class actions. We begin with an overview of data concerning all SEC enforcement actions from 1997 to 2002. We find that the volume of SEC enforcement proceedings is relatively modest. We next examine the scope of the recently enacted "Fair Fund" provision that authorizes the SEC to designate civil penalties it recovers from defendants to benefit defrauded private investors. We conclude that this provision offers only limited potential relief for private investors. We complete this Part of the Article with an analysis of the serious resource …

Prospect Theory, Risk Preference, And The Law, Chris Guthrie Nov 2003

Prospect Theory, Risk Preference, And The Law, Chris Guthrie

Vanderbilt Law School Faculty Publications

To understand how people behave in an uncertain world - and to make viable recommendations about how the law should try to shape that behavior - legal scholars must employ a model or theory of decision making. Only with an understanding of how people are likely to respond to legal rules can legal scholars, judges, legislators, and regulators craft rules that are likely to encourage desirable behavior and discourage undesirable behavior. Rather than rely on rational choice theory, behavioral law and economics scholars (or legal decision theorists) have turned to Daniel Kahneman and Amos Tversky's "prospect theory" to inform their …

Effects Of Salts On Crystallization Kinetics And Rheological Behavior Of Concentrated , -Trehalose Solutions, Marina Cerdeira, M. C. Puppo, Silvana Martini, M. L. Herrera Nov 2003

Effects Of Salts On Crystallization Kinetics And Rheological Behavior Of Concentrated , -Trehalose Solutions, Marina Cerdeira, M. C. Puppo, Silvana Martini, M. L. Herrera

Nutrition, Dietetics, and Food Sciences Faculty Publications

The effect of addition of CaCl2 2H2O and MgCl2 6H2O on crystallization kinetics and the rheological behavior of a 70% trehalose solution was studied by polarized light microscopy and dynamic oscillatory rheometry. Salts caused a delay on nucleation with induction times for crystallization longer for Mg2+ than for Ca2+. Divalent cations were incorporated into crystals, changing the growth of certain faces preferentially, which resulted in changes in morphology. Addition of CaCl2 2H2O in a high salt/trehalose molar ratio dramatically increased complex modulus (G*), indicating a stronger viscoelastic behavior. A gel-like structure was formed when Ca2+ was added to trehalose solution. …

Newspaper Coverage Of Animal Abuse, Lara Jasmine Imbrock Nov 2003

Newspaper Coverage Of Animal Abuse, Lara Jasmine Imbrock

Student Work

The abuse of animals is an important social issue. Animals play a vital role in society, serving as companions and service animals for people. A qualitative content analysis was conducted to evaluate Midwest newspaper coverage of animal abuse in 1993, 1998, and 2002. The theories of social construction of reality, agenda setting, and priming were used to examine the effects of media coverage of animal abuse. Results showed that animal abuse has received increased coverage over the years.

The Effects Of Self-Efficacy And Locus Of Control On The Sexual Behaviors Of College Females, Michelle Noah Nov 2003

The Effects Of Self-Efficacy And Locus Of Control On The Sexual Behaviors Of College Females, Michelle Noah

Student Work

This research examined the relationship between self-efficacy, locus of control, and sexual behaviors among college females. The research null hypotheses suggest that; 1) There is no correlation between self-efficacy and responsible sexual behaviors, and 2) There is no correlation between locus of control and responsible sexual behaviors. Questionnaire data were collected from 109 undergraduate females at a Midwestern University. The sample was primarily Caucasian (89%), heterosexual (96.3%), and single (73.4%) with a mean age of 23 years. An investigator designed questionnaire, adapted in part, from the Rotter Internal-External Locus of Control Scale (RIELC), The General Self-Efficacy Scale (GSE), and a …

Midazolam And Thiopentone Co-Induction: Looking For Improvement In Quality Of Anaesthesia, M A. Khan, F A. Khan Nov 2003

Midazolam And Thiopentone Co-Induction: Looking For Improvement In Quality Of Anaesthesia, M A. Khan, F A. Khan

Department of Anaesthesia

Objective: To evaluate improvement in quality of anaesthesia induction using thiopentone and midazolam for co-induction of anaesthesia. An additional end point was taken as loss of response to a tetanic stimulation (50 Hz) delivered for 5 seconds after the loss of verbal contact and eyelash reflex.Methods: Ninety ASA I and II patients, within the age range of 20-60 years were studied. Patients were randomly divided into three equal groups; A, B and group C.Results: Onset of induction and loss of response to a tetanic stimulation was achieved earlier in group B as compared to the other study groups (p < 0.05).CONCLUSION: Co-induction with midazolam 0.02 mg x kg(-1) followed by thiopentone 3 mg x kg(-1) was superior to other two groups. Induction of anaesthesia in this group was found to be smoother and faster, provided better hemodynamic stability, better airway maintenance and with lesser incidence of untoward effects.

Issue Definition And The Opinion-Policy Link: Public Preferences And Health Care Spending In The Us And Uk, Stuart N. Soroka, Elvin T. Lim Nov 2003

Issue Definition And The Opinion-Policy Link: Public Preferences And Health Care Spending In The Us And Uk, Stuart N. Soroka, Elvin T. Lim

Research Collection School of Social Sciences

This article explores the extent to which yearly changes in health spending reflect yearly changes in public preferences. Time series modelling suggests that health care spending is remarkably more responsive to yearly changes in public opinion in the US than in the UK.A content analysis of party manifestos suggests the significant role of ‘issue definition’ in accounting for this difference. Health care issues in the US have more often been viewed as problems of expenditure, while UK policy-makers have tended to focus on efficiency. Results suggest that the responsiveness of health care expenditures to public preferences in the US and …

Defects In Death-Inducing Signalling Complex Formation Prevent Jnk Activation And Fas-Mediated Apoptosis In Du 145 Prostate Carcinoma Cells, James Curtin, Thomas Cotter Nov 2003

Defects In Death-Inducing Signalling Complex Formation Prevent Jnk Activation And Fas-Mediated Apoptosis In Du 145 Prostate Carcinoma Cells, James Curtin, Thomas Cotter

Articles

Androgen-independent prostate carcinomas are resistant to chemotherapy and cell lines derived from androgen-independent prostate carcinomas such as DU 145 cells are highly resistant to Fas-mediated apoptosis. The incubation of DU 145 cells with anti-Fas IgM agonistic antibody of Fas receptor fails to activate JNK, a stress kinase involved in regulating apoptosis. We have previously shown that JNK activation is sufficient and necessary to promote Fas-mediated apoptosis in DU 145 cells. We investigate the mechanisms by which JNK activation and apoptosis are abrogated. HSP27 is overexpressed in DU 145 cells and has previously been reported to sequester DAXX and prevent JNK …

Depressive Deficits In Forgetting, Paula T. Hertel, M. Gerstle Nov 2003

Depressive Deficits In Forgetting, Paula T. Hertel, M. Gerstle

Psychology Faculty Research

The aim of this study was to investigate whether difficulties in forgetting (like difficulties in remembering) are associated with depressive states. First, dysphoric and nondysphoric students learned 40 word pairs, each consisting of a positive or negative adjective and a neutral noun (target). Next, the students practiced responding with some targets and suppressing others, when given the adjective as cue, for a varied number of repetitions. On the final test, they were told to disregard the prior instruction to suppress and to recall the target associated with every cue. Compared with nondysphoric students, dysphoric students recalled similar percentages of targets …

Transfer Of Training Emotionally Biased Interpretations, Paula T. Hertel, A. Matthews, S. Peterson, K. Kintner Nov 2003

Transfer Of Training Emotionally Biased Interpretations, Paula T. Hertel, A. Matthews, S. Peterson, K. Kintner

Psychology Faculty Research

Non-anxious college students first performed a semantic-judgement task that was designed to train either threat-related or threat-unrelated interpretations of threat-ambiguous homographs (e.g. mug). Next they performed an ostensibly separate transfer task of constructing personal mental images for single words, in a series that included new, threat-ambiguous homographs. In two experiments, the number of threat-related interpretations in the transfer task significantly increased following threat-related experience during the training phase, compared to other training conditions. We conclude that interpretive biases typically shown by anxious people can be established in non-anxious students in ways that generalize to novel tasks and materials.

Daubert & Danger: The "Fit" Of Expert Predictions In Civil Commitments, Alex Scherr Nov 2003

Daubert & Danger: The "Fit" Of Expert Predictions In Civil Commitments, Alex Scherr

Scholarly Works

The opinions of experts in prediction in civil commitment hearings should help the courts, but over thirty years of commentary, judicial opinion, and scientific review argue that predictions of danger lack scientific rigor. The United States Supreme Court has commented regularly on the uncertainty of predictive science. The American Psychiatric Association has argued to the Court that "[t]he professional literature uniformly establishes that such predictions are fundamentally of very low reliability." Scientific studies indicate that some predictions do little better than chance or lay speculation, and even the best predictions leave substantial room for error about individual cases. The sharpest …

Time Dependent Seafloor Acoustic Backscatter (10-100khz), Daniel D. Sternlicht, Christian De Moustier Nov 2003

Time Dependent Seafloor Acoustic Backscatter (10-100khz), Daniel D. Sternlicht, Christian De Moustier

Center for Coastal and Ocean Mapping

A time-dependent model of the acoustic intensity backscattered by the seafloor is described and compared with data from a calibrated, vertically oriented, echo-sounder operating at 33 and 93 kHz. The model incorporates the characteristics of the echo-sounder and transmitted pulse, and the water column spreading and absorption losses. Scattering from the water–sediment interface is predicted using Helmholtz–Kirchhoff theory, parametrized by the mean grain size, the coherent reflection coefficient, and the strength and exponent of a power-law roughness spectrum. The composite roughness approach of Jackson et al. [J. Acoust. Soc. Am. 79, 1410–1422 (1986)], modified for the finite duration of …
