A Study Of The Effect Of Reception Of Works Of Art Through An Interactive Cd-Rom, László Halász, Károly Hantos, Balázs Faa Sep 2001

A Study Of The Effect Of Reception Of Works Of Art Through An Interactive Cd-Rom, László Halász, Károly Hantos, Balázs Faa

CLCWeb: Comparative Literature and Culture

In their article, "A Study of the Effect of Reception of Works of Art through an Interactive CD-ROM," Halász, Hantos, and Faa collected data on the aesthetic impact of art objects through multimedia. They constructed a CD-ROM out of various images, sounds and text. Items were offered to 135 secondary school subjects in the framework of directed interactive polychrome variations. The effect was studied partly by measuring viewing (reading) times for each item, and partly by semantic differential and attitude scales. The data for viewing time and phases, and of items of the semantic differential and attitude scales were analyzed …

Roots Of Identity: The National And Cultural Self In Présence Africaine, Marga Graf Jun 2001

Roots Of Identity: The National And Cultural Self In Présence Africaine, Marga Graf

CLCWeb: Comparative Literature and Culture

In her article, "Roots of Identity: The National and Cultural Self in Présence Africaine," Marga Graf investigates some of the difficulties African, American, Brazilian, and Caribbean Blacks of the mid-twentieth century encountered in their attempts to voice their cultural and racial self-understanding, a self-understanding struggling to a large extent to challenge the established dichotomy between black racial inferiority versus white superiority. After the Second World War, black intellectuals meeting at the Sorbonne in Paris founded the journal Présence Africaine, a journal that became the voice of blacks investigating their history and culture throughout the different regions of Africa as well …

Improved Statistics Estimation And Feature Extraction For Hyperspectral Data Classification, Bor-Chen Kuo, David Landgrebe Jun 2001

Improved Statistics Estimation And Feature Extraction For Hyperspectral Data Classification, Bor-Chen Kuo, David Landgrebe

Department of Electrical and Computer Engineering Technical Reports

For hyperspectral data classification, the avoidance of singularity of covariance estimates or excessive near singularity estimation error due to limited training data is a key problem. This study is intended to solve problem via regularized covariance estimators and feature extraction algorithms. A second purpose is to build a robust classification procedure with the advantages of the algorithms proposed in this study but robust in the sense of not requiring extensive analyst operator skill. A pair of covariance estimators called Mixed-LOOCs is proposed for avoiding excessive covariance estimator error. Mixed-LOOC2 has advantages over LOOC and BLOOC and needs less computation than …

Comparativist Interpretations Of The Frontier In Early American Fiction And Literary Historiography, Barbara Buchenau Jun 2001

Comparativist Interpretations Of The Frontier In Early American Fiction And Literary Historiography, Barbara Buchenau

CLCWeb: Comparative Literature and Culture

In her article, "Comparativist Interpretations of the Frontier in Early American Fiction and Literary Historiography," Barbara Buchenau points towards problematic processes of selection and narrative positioning at work in historiographical studies when analyzing and synthesizing early American frontier fiction. Apart from selecting only a small number of literary texts from the large pool of frontier fiction, these over-arching narratives tend to reduce the meaning of the literary works selected to those characteristics that are understood to be of importance for the emerging national literature. Concentrating on two novels long excluded from the American canon, Catharine Maria Sedgwick's Hope Leslie (1827) …

From Redskin To Redneck: Atrocity And Revenge In American Writing, Terence Martin Jun 2001

From Redskin To Redneck: Atrocity And Revenge In American Writing, Terence Martin

CLCWeb: Comparative Literature and Culture

In his article, "From Redskin to Redneck: Atrocity and Revenge in American Writing," Terence Martin argues that one of the basic narrative patterns in American writing is that of revenge for the violation of innocence. Martin explores in his study Robert Montgomery Bird's Nick of the Woods, Brian Garfield's Death Wish, and John Grisham's A Time to Kill, texts in which ambiguities of the pattern are expressed in a dramatic and disquieting fashion. After brutality to innocent victims precipitates the action, each of these novels identifies predators and revenge figures and thus sets in motion an escalating spectacle of retribution. …

A Comparative Analysis Of Studies On Heat Transfer And Fluid Flow In Microchannels, Choondal B. Sobhan, Suresh V. Garimella Apr 2001

A Comparative Analysis Of Studies On Heat Transfer And Fluid Flow In Microchannels, Choondal B. Sobhan, Suresh V. Garimella

CTRC Research Publications

The extremely high rates of heat transfer obtained by employing microchannels makes them an attractive alternative to conventional methods of heat dissipation, especially in applications related to the cooling of microelectronics. A compilation and analysis of the results from investigations on fluid flow and heat transfer in micro- and mini-channels and microtubes in the literature is presented in this review, with a special emphasis on quantitative experimental results and theoretical predictions. Anomalies and deviations from the behavior expected for conventional channels, both in terms of the frictional and heat transfer characteristics, are discussed.

Investigating Probabilistic Constraint Dependency Grammars In Language Modeling, Wen Wang, Mary P. Harper Apr 2001

Investigating Probabilistic Constraint Dependency Grammars In Language Modeling, Wen Wang, Mary P. Harper

Department of Electrical and Computer Engineering Technical Reports

This technical report concerns the development of a probabilistic Constraint Dependency Grammar (CDG) language model for speech recognition tasks. We have developed methods to quickly annotate a medium-sized carpus of sentences and extract high quality CDGs. We have also evaluated the quality of these grammars. Using the corpus of CDG parses, we have constructed and evaluated a language model that incorporates syntactically a.nd semantically enriched Part-of-Speech (POS) tags. The N-gram language model based on the enriched tags improves the perplexity and word error rate on the test corpus compared to a standard word-based N-gram language model and an N-gram POS-based …

Gender, Literature, And Film In Contemporary East Central European Culture, Anikó Imre Mar 2001

Gender, Literature, And Film In Contemporary East Central European Culture, Anikó Imre

CLCWeb: Comparative Literature and Culture

In her article, "Gender, Literature, and Film in Contemporary East Central European Culture," Anikó Imre discusses gender, literature, and film in Hungary in the context of East Central European national cultures of the 1980s and 1990s. Anikó Imre analyzes the analogous gender structures that underlie both nation and literature in these transitional cultures. She challenges both social science studies of post-communist transitions and studies of East Central European literatures and cultures for their traditional neglect of gendered desire as a political factor. Thereby, Imre adopts a deconstructionist, feminist, and post-colonial approach to Hungarian "postmodernist" literature and film, which, similar to …

International Monetary Trade And The Law Of One Price, Gabriele Camera, Johannes Winkler Jan 2001

International Monetary Trade And The Law Of One Price, Gabriele Camera, Johannes Winkler

Purdue CIBER Working Papers

We endogenize circulation of currencies and price formation in a decentralized monetary trading environment with two countries and two currencies. In equilibrium sellers of homogenous goods may post prices in the national or also in the foreign currency, given unobservable buyers. valuations. We prove that, under different monetary regimes, the absence of well integrated international goods markets doesn.t necessarily imply a violation of the law of one price. We also illustrate the behavior of prices across regimes characterized by different degrees of monetary integration.

Gresham's Law Versus Currency Competition, Gabriele Camera, Ben Craig, Christopher J. Waller Jan 2001

Gresham's Law Versus Currency Competition, Gabriele Camera, Ben Craig, Christopher J. Waller

Purdue CIBER Working Papers

We develop a dual currency search model where agents can hold currency portfolios to buy goods, and analyze an agent's choice to spend safe dollars or risky home currency for internal trade. We focus on two equilibria: a currency competition equilibrium, in which the 'good' currency (dollars) is spent first and the 'bad' (risky home) currency is kept for later purchases, and a Gresham's Law equilibrium in which agents do the reverse. We prove that for the Gresham's Law equilibrium to prevail, trading frictions and the home currency risk must be small. Otherwise, extensive currency substitution occurs and the currency …

Parameter Estimation And Measures Of Fit In A Global, General Equilibrium Model, Jing Liu, Channing Arndt, Thomas Hertel Jan 2001

Parameter Estimation And Measures Of Fit In A Global, General Equilibrium Model, Jing Liu, Channing Arndt, Thomas Hertel

GTAP Working Papers Archive

Computable General Equilibrium (CGE) models have been widely used for quantitative analysis of global economic issues. However, CGE models are frequently criticized for resting on weak empirical foundations. This paper builds on recent work in macro-econometric estimation, developing an approach to parameter estimation for a widely employed global CGE model, the Global Trade Analysis Project (GTAP) model. An approximate likelihood function is developed and the set of optimum elasticity values is obtained by maximizing this approximate likelihood function in the context of a back casting exercise. In addition, two statistical tests are performed. The first of these tests compares the …

Time As A Trade Barrier, David Hummels Jan 2001

Time As A Trade Barrier, David Hummels

GTAP Working Papers Archive

International trade occurs in physical space and moving goods requires time. This paper examines the importance of time as a trade barrier, estimates the magnitude of time costs, and relates these to patterns of trade and the international organization of production. Estimates indicate that each additional day spent in transport reduces the probability that the US will source from that country by 1 – 1.5 percent. Conditional on exporting country, estimates directly identify a willingness-to-pay for time savings using variation across exporters and commodities in the relative price / speed tradeoff for air and ocean shipping. Each day saved in …

Consensus Evidence Evaluation In Resuscitation Research: Analysis Of Type I And Type Ii Errors, Charles F. Babbs Jan 2001

Consensus Evidence Evaluation In Resuscitation Research: Analysis Of Type I And Type Ii Errors, Charles F. Babbs

Weldon School of Biomedical Engineering Faculty Publications

Objective: This paper addresses the following statistical question: ‘if genuine improvements in cardiopulmonary resuscitation (CPR) were discovered that doubled the probability of resuscitation success in a series of randomized clinical trials, would they be recognized and incorporated into consensus guidelines?’ Methods: Statistical powers for hypothetical individual clinical trials comparing experimental and control CPR were computed as a function of the study N when the true probabilities for immediate survival, 24 h survival, and discharge survival in the experimental group were twice those in the control group. Next, the binomial distributions describing the numbers of statistically significant studies in a series …

Simulating Quasi-Ballistic Transport In Si Nanotransistors, Kausar Banoo, Jung-Hoon Rhew, Mark S. Lundstrom, Chi-Wang Shu, Joseph W. Jerome Jan 2001

Simulating Quasi-Ballistic Transport In Si Nanotransistors, Kausar Banoo, Jung-Hoon Rhew, Mark S. Lundstrom, Chi-Wang Shu, Joseph W. Jerome

Department of Electrical and Computer Engineering Faculty Publications

Electron transport in model Si nanotransistors is examined by numerical simulation using a hierarchy of simulation methods, from full Boltzmann, to hydrodynamic, energy transport, and drift-diffusion. The on-current of a MOSFET is shown to be limited by transport across a low-field region about one mean-free-path long and located at the beginning of the channel. Commonly used transport models based on simplified solutions of the Boltzmann equation are shown to fail under such conditions. The cause for this failure is related to the neglect of the carriers' drift energy and to the collision-dominated assumptions typically used in the development of simplified …
