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 …

Automated Rating Of Esl Essays, Deryle W. Lonsdale, Diane Strong-Krause

Faculty Publications

To date, traditional NLP parsers have not been widely successful in TESOLoriented applications, particularly in scoring written compositions. Re-engineering such applications to provide the necessary robustness for handling ungrammatical English has proven a formidable obstacle. We discuss the use of a nontraditional parser for rating compositions that attenuates some of these difficulties. Its dependency-based shallow parsing approach provides significant robustness in the face of language learners’ ungrammatical compositions. This paper discusses how a corpus of L2 essays for English was rated using the parser, and how the automatic evaulations compared to those obtained by manual methods. The types of modifications …

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 …

An Evaluation Of Factors Related To The Disproportionate Representation Of Children Of Color In Santa Clara County’S Child Welfare System: Child And Family Characteristics And Pathways Through The System Phase 2, Alice Hines, Peter Lee, Laurie Drabble, Lonnie Snowden, Kathy Lemon Osterling

Faculty Publications

While child abuse and neglect appears to affect children of all racial and ethnic origins (US Department of Health and Human Services, 1998; Sedlack & Broadhurst, 1996), an analysis of national, California and Santa Clara County data on the ethnicities of children in out of home placement reveals that, compared to their presence in the general population, there is a disproportionate involvement of children of color in the public child welfare system (CWS). In Santa Clara County, in particular, when compared to the general population, African American, Hispanic/Latino and Native American children are overrepresented in the CWS, while Asian American/Pacific …

Interdisciplinarity: The Road Ahead For Education In Digital Libraries, Anita Coleman

Faculty Publications

This article reviews the state of education in digital libraries and curriculum planning documents from professional associations in two areas: Library and Information Science; and Computing. It examines suggestions for integration and interdisciplinarity in education for digital libraries curricula using definitions of a discipline, interdisciplinarity, and the transdisciplinary structure of a university in order to discover how such integration may be successfully accomplished. A plan to use learning communities and develop an interdisciplinary curriculum for Knowledge Organization is briefly discussed.

Machine-Learned Contexts For Linguistic Operations In German Sentence Realization, Eric K. Ringger, Simon Corston-Oliver, Michael Gamon, Robert Moore

Faculty Publications

We show that it is possible to learn the contexts for linguistic operations which map a semantic representation to a surface syntactic tree in sentence realization with high accuracy. We cast the problem of learning the contexts for the linguistic operations as classification tasks, and apply straightforward machine learning techniques, such as decision tree learning. The training data consist of linguistic features extracted from syntactic and semantic representations produced by a linguistic analysis system. The target features are extracted from links to surface syntax trees. Our evidence consists of four examples from the German sentence realization system code-named Amalgam: case …

Improving Speech Recognition Learning Through Lazy Training, Tony R. Martinez, Michael E. Rimer, D. Randall Wilson

Faculty Publications

Multi-layer backpropagation, like most learning algorithms that can create complex decision surfaces, is prone to overfitting. We present a novel approach, called lazy training, for reducing the overfit in multiple-layer networks. Lazy training consistently reduces generalization error of optimized neural networks by more than half on a large OCR dataset and on several real world problems from the UCI machine learning database repository. Here, lazy training is shown to be effective in a multi-layered adaptive learning system, reducing the error of an optimized backpropagation network in a speech recognition system by 50.0% on the TIDIGITS corpus.

Legal Theory And The Rule Of Law, Noel B. Reynolds

Faculty Publications

In "Legal Theory and the Rule of Law" Noel Reynolds maintains that the rule of law can be understood as a set of conditions that rational actors would impose on any authority they would create to act in their stead in creating and administering legally binding rules. The authority and obligation associated with law derive from this fundamental convention, and the principles of the rule of law are the conditions of that agreement, which become thereby governing principles to which legislatures, judges, and enforcement agencies can be held in their official actions. These generally recognized standards are inherent in this …

Brandenburg And The United States War On Incitement Abroad: Defending A Double Standard, Lyrissa Lidsky

Faculty Publications

While it is perfectly legitimate for the United States to attempt to persuade foreign citizens and media not to engage in advocacy of violent acts, the administration's rhetoric suggests that the United States expects foreign governments to take action against speech that would be protected by the First Amendment in the United States. What explains this apparent hypocrisy? Is this simply another example of the United States touting democracy at home while supporting despotism abroad? Or is the Brandenburg incitement standard so socially and culturally contingent that it is not appropriate for export, at least to the Arab Middle East? …

Ethnic-Difference Markers For Use In Mapping By Admixture Linkage Disequilibrium, Heather E. Collins-Schramm, Carolyn M. Phillips, Darwin J. Operario, Jane S. Lee, James L. Weber, Robert L. Hanson, William C. Knowler, Richard Cooper, Hongzhe Li, Michael F. Seldin

Faculty Publications

Mapping by admixture linkage disequilibrium (MALD) is a potentially powerful technique for the mapping of complex genetic diseases. The practical requirements of this method include (a) a set of markers spanning the genome that have large allele-frequency differences between the parental ethnicities contributing to the admixed population and (b) an understanding of the extent of admixture in the study population. To this end, a DNA-pooling technique was used to screen microsatellite and diallelic insertion/deletion markers for allele-frequency differences between putative representatives of the parental populations of the admixed Mexican American (MA) and African American (AA) populations. Markers with promising pooled …

Are Plurals Derived Or Stored?, David Eddington, Patricia Lestrade

Faculty Publications

The ability to produce and comprehend human language involves at least two processes: the storage of units and the computations performed on those units. The role that storage and computation play in the processing of inflectional morphology is highly debated. At one end of the spectrum is the full storage model, which holds that all known words, whether morphologically complex or not, have separate entries in the mental lexicon (Jackendoff 1975, Manelis and Tharp 1977, Butterworth 1983, Bybee 1985, 1988, Rumelhart and McClelland 1986, McClelland 1988, Stemberger 1994, Rueckl, Mikolinski, Raveh, Miner, and Mars 1997). This position puts an enormous …

Corporate And Products Identity In The Post-National Economy: Rethinking U.S. Trade Laws, Lan Cao

Faculty Publications

In the global economy, a General Motors automobile may involve South Korean assembly; Japanese engines; German design and style engineering; Taiwanese, Singaporean, and Japanese small components; British advertising and marketing; and Irish and Barbadian data processing. What is the country of origin of this product? How should U.S. trade laws evaluate a product's origin, if it is a global composite with research, assembly, processing, and manufacturing performed in different countries? Similarly, corporations have become increasingly global in orientation and operations. Even "national" corporations have lost their territorial ties to the state of their nationality. Through a phenomenon termed "global outsourcing" …

The Many Uses Of Digitized Oral History Collections: Implications For Design, Dagobert Soergel, Douglas W. Oard, Samuel Gustman, Lydia Fraser, Jinmook Kim, Joan Meyer, Elizabeth Proffen, Theresa Sartori

Faculty Publications

Oral history - and spoken word collections generally - are assuming increasing importance in digital libraries as the storage, transmission and reproduction infrastructure improves. This paper describes three synergistic approaches to user needs analysis, explains how they are being applied to guide the design of systems to provide access oral history collections (using a s test bed the Shoah Foundations collection of over 50,000 videotaped oral history interviews), presents preliminary results from so -called “discount requirements analysis” and an analysis of “early access” requests, and draws some design implications. The results show a wide variety of users and uses of …

The Influence Of Pitch And Loudness Changes On The Acoustics Of Vocal Tremor, Christopher Dromey, Paul Warrick, Jonathan Irish

Faculty Publications

The effect of tremor on phonation is to modulate an otherwise steady sound source in its amplitude, fundamental frequency, or both. The severity of untreated vocal tremor has been reported to change under certain conditions that may be related to muscle tension. In order to better understand the phenomenon of vocal tremor, its acoustic properties were examined as individuals volitionally altered their pitch and loudness. These voice conditions were anticipated to alter the tension of the intrinsic laryngeal muscles. The voices of 10 individuals with a diagnosis of vocal tremor were recorded before participating in a longitudinal treatment study. They …

Peppering Knowledge Sources With Salt: Boosting Conceptual Content For Ontology Generation, Deryle W. Lonsdale, Yihong Ding, David W. Embley, Alan Melby

Faculty Publications

This paper describes work done to explore the common ground between two different ongoing research projects: the standardization of lexical and terminological resources, and the use of conceptual ontologies for information extraction and data integration. Specifically, this paper explores improving the generation of extraction ontologies through use of a comprehensive terminology database that has been represented in a standardized format for easy tool-based implementation. We show how, via the successful integration of these two distinct efforts, it is possible to leverage large-scale terminological and conceptual information having relationship-rich semantic resources in order to reformulate, match, and merge retrieved information of …

A Categorial Grammar Fragment For Lushootseed, Deryle W. Lonsdale

Faculty Publications

This paper establishes a basic framework for a Categorial Grammar (CG) description ofLushootseed morpho syntax and semantics. After a brief review of English CG principles, a preliminary attempt is made to apply these fundamentals to Lushootseed free and bound morphemes. Several sample derivations are presented. including one rather complex syntactic ambigiuty previously noted in the literature with its alternative descriptions. Once the syntactic elements have been put in place a short overview is presented of how semantic interpretation can be established in tandem with syntactic composition principles. Finally, the implementation of this framework within the Attribute Logic Engine environment is …

Why Quantitative?, David Eddington

Faculty Publications

It is generally the case that special volumes include studies on a narrowly defined topic of linguistic investigation from a single theoretical standpoint. A glance at the table of contents of the present issuem on the other hand, reveals an eclectic group of papers with topics ranging from second-language acquisition to feature theory. In addition to the variety of topics covered, it should be noted that a wide variety of theoretical frameworks is represented. The present volume contains the work of researchers who assume structuralist, generative, functionalist, and psycholinguistic perspectives. Nevertheless, the thread that ties these studies together is that …

Maternal Psychological Control And Preschool Children’S Behavioral Outcomes In China, Russia, And The United States, Susanne Frost Olsen, Chongming Yang, Craig H. Hart, Clyde C. Robinson, Peixia Wu, David A. Nelson, Larry J. Nelson, Shenghua Jin, Jianzhong Wo

Faculty Publications

A growing body of Western literature has demonstrated the importance of three domains of socialization—connection with significant others, regulation of behavior, and the facilitation of psychological autonomy—in predicting outcomes in adolescents and children (Barber, 1997a, 1997b; Gray & Steinberg, 1999; Hart, Newell, & Olsen, in press; Nelson, 1997; Steinberg, Dornbusch, & Brown, 1992). Psychological control—parenting that does not allow children psychological autonomy, as has been defined elsewhere in this volume, has received increased attention in the past decade (for a discussion of definitions and research, see chapter 2, this volume).
