A Controlled Evaluation Of A Comprehensive Mental Skills Program For Ncaa And Youth Club Swimmers, Kevin Matthew Lancer Jan 2003

A Controlled Evaluation Of A Comprehensive Mental Skills Program For Ncaa And Youth Club Swimmers, Kevin Matthew Lancer

UNLV Retrospective Theses & Dissertations

Previous studies have established that mental skills training is an effective intervention for improving performance in athletes. Relaxation, imagery, and mental preparation interventions have demonstrated efficacy in the improvement of athletic performance. However, relaxation combined with imagery is more effective than either one alone. Similarly, past studies have indicated mental preparation interventions may be more effective in the improvement of athletic performance when combined with other interventions. In team sports such as swimming, optimum performance has been found to improve cohesion. However, whether cohesion leads to improvements in sports performance is undetermined. In this study, a multiple baseline across team …

Recognition And Identification Of Form Document Layouts, Kai Luo Jan 2003

Recognition And Identification Of Form Document Layouts, Kai Luo

UNLV Retrospective Theses & Dissertations

In this thesis, a hierarchical tree representation is introduced to represent the logical structure of a form document. But different forms might have the same logical structure, so the representation will be ambiguous. In this thesis, an improvement is proposed to solve the ambiguity problem by using the physical information of the blocks. To fulfill the application of hierarchical tree representation and extract the physical information of blocks, a pixel tracing approach is used to extract form layout structures from form documents. Compared with Hough transform, the pixel tracing algorithm requires less computation. This algorithm has been tested on 50 …

"In That New World Which Is The Old": New World/Old World Inversion In Aldous Huxley's "Brave New World", Oliver Quimby Melton Jan 2003

"In That New World Which Is The Old": New World/Old World Inversion In Aldous Huxley's "Brave New World", Oliver Quimby Melton

UNLV Retrospective Theses & Dissertations

"'In That New World Which Is The Old': New World/Old World Inversion In Aldous Huxley's Brave New World" examines the inversion of the concepts Old World, specifically associated with England, and New World, specifically associated with America, in the novel Brave New World. After examining and denotatively defining the terms Old World and New World, this thesis argues that the New World/Old World inversion in Huxley's dystopian novel exists because of Anglo-American cultural and political events of the 1920s and early 1930s, namely, the United States' rise as a military, political, and cultural superpower following World War I and Great …

A Graphical Approach For Goodness-Of-Fit Of Poisson Model, Davin P Padilla Jan 2003

A Graphical Approach For Goodness-Of-Fit Of Poisson Model, Davin P Padilla

UNLV Retrospective Theses & Dissertations

Extensive work has been done on goodness-of-fit (GOF) tests for data assumed to have come from univariate continuous distributions; however, literature on GOF procedures for univariate discrete distributions is rather sparse in compariSon The Poisson distribution in particular has received much attention in the study of GOF tests due to its numerous applications as a model for observable phenomena. Hence, we survey existing GOF tests for Poissonity and present a useful guide to the most commonly used distribution-free GOF tests in practice. We then propose and investigate a graphical test of fit for the Poisson model that is based on …

Identification Of Headers And Footers In Noisy Documents, Qin Liu Jan 2003

Identification Of Headers And Footers In Noisy Documents, Qin Liu

UNLV Retrospective Theses & Dissertations

Optical Recognition Technology is typically used to convert hard copy printed material into its electronic form. Many presentational artifacts such as end-of-line hyphenations, running headers and footers are literally converted. These artifacts can possibly hinder proximity and exact match searching; This thesis develops an algorithm to extract running headers and footers from electronic documents generated by OCR. This method associates each page of the document with its neighboring pages and detects the headers and footers by comparing the page with its neighboring pages. Experiments are also taken to test the effectiveness of these algorithms.

Thesaurus-Aided Learning For Rule-Based Categorization Of Ocr Texts, Jeffrey Scott Coombs Jan 2003

Thesaurus-Aided Learning For Rule-Based Categorization Of Ocr Texts, Jeffrey Scott Coombs

UNLV Retrospective Theses & Dissertations

The question posed in this thesis is whether the effectiveness of the rule-based approach to automatic text categorization on OCR collections can be improved by using domain-specific thesauri. A rule-based categorizer was constructed consisting of a C++ program called C-KANT which consults documents and creates a program which can be executed by the CLIPS expert system shell. A series of tests using domain-specific thesauri revealed that a query expansion approach to rule-based automatic text categorization using domain-dependent thesauri will not improve the categorization of OCR texts. Although some improvement to categorization could be made using rules over a mixture of …

Power, Legitimation, And Drawing Distinctions: Rendering Of 'Public' And 'Private' In United States Domestic Violence Policymaking, Christina R Drum

UNLV Retrospective Theses & Dissertations

Contested claims about the public/private distinction have always been central to liberal democratic principles, to feminist ideologies, and (more narrowly) to domestic violence policymaKing Historically, treatment of domestic violence as a phenomenon that is relegated to the so-called 'private sphere' has served as justification for limiting such public policy remedies as prevention, intervention and recovery initiatives; From the grassroots battered women's movements of the 1970s to the current network of shelters, community agencies and advocacy groups, the last several decades have seen significant progress toward increasing public and political awareness of domestic violence. In the United States, many of these …

The Psychological Impact Of Carrier Status In Hereditary Disorders, Jane Elizabeth Karwoski Jan 2003

The Psychological Impact Of Carrier Status In Hereditary Disorders, Jane Elizabeth Karwoski

UNLV Retrospective Theses & Dissertations

Previous studies have indicated that carrier status has little effect on self-concept. However, rather than examine autosomal recessive illnesses, wherein genetic responsibility is shared by both parents, the present study samples women at risk of being sole carriers of an X-linked hereditary disorder, Duchenne muscular dystrophy. Previous research most often assessed global self-esteem, thus problems in particular domains (such as future parental role or desirability as a mate) have generally been overlooked. Herein, a stigmatizing process is hypothesized whereby one aspect of the self, genetic identity, may be spoiled through a diminished sense of worthiness to reproduce. Family attitudes toward …
