The Effect Of Adult Sportsmanship And Pro-Social Behavior Modeling On Child Self-Competence In Youth Football Programs, Bryan Scott Wilson Dec 2010

The Effect Of Adult Sportsmanship And Pro-Social Behavior Modeling On Child Self-Competence In Youth Football Programs, Bryan Scott Wilson

Communication & Leadership Dissertations and Theses

Youth sports are viewed as a prime venue for teaching social values and life skills. By virtue of their organizing and leadership positions, adults play a critical role in communicating these lessons. Although there is little debate on the criticality of positive sportsmanship, there has been a serious trend in increasingly unsportsmanlike behaviors at youth events. In response, many organizations have implemented programs designed to increase positive adult sportsmanship communications and pro-social behaviors. While studies have shown that training does result in increased sportsmanship, less information is available on the impacts of such programs beyond increasing the “fun factor.” This …

Piedras Blancas Clock Works, Andrew James, Andrew Jupin, Matt Weber Dec 2010

Piedras Blancas Clock Works, Andrew James, Andrew Jupin, Matt Weber

Mechanical Engineering

In 1875, the Piedras Blancas Lighthouse was built to warn ships sailing the California coast of the hazards of the rocky shore. In 1949 a fierce storm damaged the top portion of the lighthouse and the eight ton cast iron and brass assembly had to be replaced by a much lighter piece that still served the purpose of warning oncoming vessels. The former top portion came to rest in downtown Cambria and is still there today, enclosed in a glass room to be observed by visitors and townspeople. Today, the Piedras Blancas Light station is cared for by the Bureau …

A Dynamic Approach To Determine The Product Flow Nature In Apparel Supply Chain Network, Mohammed Marufuzzaman, Ahmed M. Deif Dec 2010

A Dynamic Approach To Determine The Product Flow Nature In Apparel Supply Chain Network, Mohammed Marufuzzaman, Ahmed M. Deif

Industrial Technology and Packaging

This paper presents a novel metric, product flow number, to determine the product flow nature across the supply chain of apparel industries. The metric is based on mapping the dynamics of fluid flow across a pipe to product flow across a supply chain. Numerical analysis is conducted to examine the impact of the different metric parameters on the product flow. Results showed that smooth dynamics can be achieved through scaling production and extending delivery times, while undesirable dynamics are tied to complex product designs and increasing number of suppliers. Finally, the paper demonstrated how the new metric can be used …

We present a measurement of the WW+WZ production cross section observed in a final state consisting of an identified electron or muon, two jets, and missing transverse energy. The measurement is carried out in a data sample corresponding to up to 4.6fb⊃-1 of integrated luminosity at √s=1.96TeV collected by the CDF II detector. Matrix element calculations are used to separate the diboson signal from the large backgrounds. The WW+WZ cross section is measured to be 17.4±3.3pb in agreement with standard model predictions. A fit to the dijet invariant mass spectrum yields a compatible cross section measurement. © 2010 The American …

The Laser Interferometer Gravitational Wave Observatory (LIGO) is a network of three detectors built to detect local perturbations in the spacetime metric from astrophysical sources. These detectors, two in Hanford, WA and one in Livingston, LA, are power-recycled Fabry-Perot Michelson interferometers. In their fifth science run (S5), between November 2005 and October 2007, these detectors accumulated one year of triple coincident data while operating at their designed sensitivity. In this paper, we describe the calibration of the instruments in the S5 data set, including measurement techniques and uncertainty estimation. © 2010 Elsevier B.V. All rights reserved.

A trade-off between growth and mortality rates characterizes tree species in closed canopy forests. This trade-off is maintained by inherent differences among species and spatial variation in light availability caused by canopy-opening disturbances. We evaluated conditions under which the trade-off is expressed and relationships with four key functional traits for 103 tree species from Barro Colorado Island, Panama. The trade-off is strongest for saplings for growth rates of the fastest growing individuals and mortality rates of the slowest growing individuals (r2 = 0.69), intermediate for saplings for average growth rates and overall mortality rates (r 2=0.46), and much weaker for …

Identification and characterization of the genetic variants underlying type 2 diabetes susceptibility can provide important understanding of the etiology and pathogenesis of type 2 diabetes. We previously identified strong evidence of linkage for type 2 diabetes on chromosome 22 among 3,383 Hypertension Genetic Epidemiology Network (HyperGEN) participants from 1,124 families. The checkpoint 2 (CHEK2) gene, an important mediator of cellular responses to DNA damage, is located 0.22 Mb from this linkage peak. In this study, we tested the hypothesis that the CHEK2 gene contains one or more polymorphic variants that are associated with type 2 diabetes in HyperGEN individuals. In …


Interrogating Local Population Structure For Fine Mapping In Genome-Wide Association Studies, Huaizhen Qin, Nathan Morris, Sun J. Kang, Mingyao Li, Bamidele Tayo, Helen Lyon, Joel Hirschhorn, Richard S. Cooper, Xiaofeng Zhu Dec 2010

Interrogating Local Population Structure For Fine Mapping In Genome-Wide Association Studies, Huaizhen Qin, Nathan Morris, Sun J. Kang, Mingyao Li, Bamidele Tayo, Helen Lyon, Joel Hirschhorn, Richard S. Cooper, Xiaofeng Zhu

Faculty Publications

Motivation: Adjustment for population structure is necessary to avoid bias in genetic association studies of susceptibility variants for complex diseases. Population structure may differ from one genomic region to another due to the variability of individual ancestry associated with migration, random genetic drift or natural selection. Current association methods for correcting population stratification usually involve adjustment of global ancestry between study subjects.Results: We suggest interrogating local population structure for fine mapping to more accurately locate true casual genes by better adjusting the confounding effect due to local ancestry. By extensive simulations on genome-wide datasets, we show that adjusting global ancestry …


Semantic Enrichment Of Text Representation With Wikipedia For Text Classification, Hiroki Yamakawa, Jing Peng, Anna Feldman Dec 2010

Semantic Enrichment Of Text Representation With Wikipedia For Text Classification, Hiroki Yamakawa, Jing Peng, Anna Feldman

Department of Computer Science Faculty Scholarship and Creative Works

Text classification is a widely studied topic in the area of machine learning. A number of techniques have been developed to represent and classify text documents. Most of the techniques try to achieve good classification performance while taking a document only by its words (e.g. statistical analysis on word frequency and distribution patterns). One of the recent trends in text classification research is to incorporate more semantic interpretation in text classification, especially by using Wikipedia. This paper introduces a technique for incorporating the vast amount of human knowledge accumulated in Wikipedia into text representation and classification. The aim is to …


Characteristics Of Effective Interpreter Education Programs In The United States, Lisa Ann Boegner Godfrey Dec 2010

Characteristics Of Effective Interpreter Education Programs In The United States, Lisa Ann Boegner Godfrey

Masters Theses and Doctoral Dissertations

The general purpose of this study was to investigate effective practices of interpreting education programs in the United States as measured by the readiness to credential gap. The increasing demand for interpreters has created an environment with under-credentialed interpreters and this is compounded by the fact that the field of interpreter education is relatively new and little research has been done regarding interpreter education. There has been much dispute as to the content and experiences sign language interpreting programs need to include, but there have been no clearly identified characteristics of successful interpreter education program s shown to result in …

Agreement Between Clinician And Patient Ratings Of Adaptive Functioning And Developmental History, Jared A. Defife, Rebecca Drill, Ora Nakash, Drew Westen

School for Social Work: Faculty Publications

Objective: Psychiatric researchers rely heavily on patient report data for clinical research. However, patient reports are prone to defensive and self-presentation biases. Recent research using practice networks has relied on clinician reports, and both forensic and personality disorder researchers have recently turned to quantified data from clinically expert observers as well. However, critics have raised legitimate concerns about the reliability and validity of data from clinician informants. The aim of this study was to assess the validity and diagnostic efficiency of clinician reports of their patients' adaptive functioning and developmental histories, using patient reports as the comparative standard traditionally used …

Survey results found that less than half of the sample was aware of any one of the programs. A logit model was developed …


Synthesis Of Reversible Circuits For Large Reversible Functions, Marek Perkowski, Nouraddin Alhagi, Maher Hawash Dec 2010

Synthesis Of Reversible Circuits For Large Reversible Functions, Marek Perkowski, Nouraddin Alhagi, Maher Hawash

Electrical and Computer Engineering Faculty Publications and Presentations

This paper presents a new algorithmMP (multiple pass) to synthesize large reversible binary circuits without ancilla bits. The well-known MMD algorithm for synthesis of reversible circuits requires to store a truth table (or a Reed-Muller - RM transform) as a 2n vector to represent a reversible function of n variables. This representation prohibits synthesis of large functions. However, in MP we do not store such an exponentially growing data structure. The values of minterms are calculated in MP dynamically, one-by-one, from a set of logic equations that specify the reversible circuit to be designed. This allows for synthesis of large …


The Supreme Court’S Assault On Litigation: Why (And How) It Could Be Good For Health Law, Abigail R. Moncrieff Dec 2010

The Supreme Court’S Assault On Litigation: Why (And How) It Could Be Good For Health Law, Abigail R. Moncrieff

Law Faculty Articles and Essays

In recent years, the Supreme Court has narrowed or eliminated private rights of action in many legal regimes, much to the chagrin of the legal academy. That trend, although certainly not limited to health law, has had a significant impact on the field; the Court's decisions have eliminated the private enforcement mechanism for at least three important healthcare regimes: Medicaid, employer-sponsored insurance, and medical devices. In a similar trend outside the courts, state legislatures have capped non-economic and punitive damages for medical malpractice litigation, weakening the tort system's deterrent capacity in those states. This Article suggests that the trend of …

A Fiber Bragg Grating-Based All-Fiber Sensing Systems For Telerobotic Cutting Applications, Ginu Rajan, Dean Callaghan, Yuliya Semenova, Mark Mcgrath, Eugene Coyle, Gerald Farrell

Articles

A fiber Bragg grating (FBG)-based strain sensing system for minimally invasive telerobotic cutting applications is presented in this paper. Investigations assume that a scissor blade can be approximated as a uniformly tapered cantilever beam. A replica of the scissor blade is produced and strain characterization has been carried out using an FBG sensor system. Results are validated against measurements obtained using conventional electrical resistance strain gauges. The scissor blade experiences both direct and lateral forces during cutting, hence the system is characterized for a direct load range of 0-30 N and a lateral load range of 0-10 N. The results …

A confirmatory method has been developed to allow for the analysis of fourteen prohibited medicinal additives in pig and poultry compound feed. These compounds are prohibited for use as feed additives although some are still authorised for use in medicated feed. Feed samples are extracted by acetonitrile with addition of sodium sulphate. The extracts undergo a hexane wash to aid with sample purification. The extracts are then evaporated to dryness and reconstituted in initial mobile phase. The samples undergo an ultracentrifugation step prior to injection onto the LC-MS/MS system and are analysed in a run time of 26 minutes. The …
