An In Vitro Evaluation Of The Elements Apex Locator Using The Endo Q System, Steven Andrew Brofsky

Theses and Dissertations

The objective of this study was two-fold: 1) to determine the accuracy of the Elements Apex Locator and 2) to compare the accuracy of the alginate and Endo Q models as in-vitro apex locator testing devices. Twenty teeth were decoronated at the CEJ and triplicate measurements were made using the Elements Apex Locator. All measurements were made to the apex reading of the apex locator. True length was established by visualizing the file tip at the apex with a dental operating microscope. Measurements were then taken with the teeth mounted in an alginate model and then in the Endo Q …

Soul Hunting, Guido Esteban Alvarez

Theses and Dissertations

According to the Webster's unabridged dictionary, a mania is an excessively intense enthusiasm, interest, or desire; a craze. I experience a mania on a daily basis: I take photographs. I trap photographs inside flat, airless fish tanks where time stands still. The creatures captured inside the tanks resurrect every time I see them to remind me of a sound, an odor, a flavor, and, ultimately, a feeling I once experienced and now cherish. This project will attempt to show the energy captured in my photographic archives as a journey through my memories using an experimental interactive method.

Human Genetic Variation And Health: New Assessment Approaches Based On Ethnogenetic Layering, Fatimah Linda Collier Jackson

Department of Biology Faculty Publications

Human genetic variation is often biologically relevant, particularly when it influences (or is influenced by) health outcomes. For example, human genetic variation can modulate disease aetiology as in the case ofhomozygous beta sickle gene (βS/βS or sickle cell) pathology. Conversely, health outcomes, such as the frequency and duration of homozygous sickle cell pathology, can change affected group gene frequencies by selectively targeting and culling specific genotypes in a group, such as clinically more severe βS Bantu/βS Bantu versions of the βS gene, thereby changing future patterns of genetic variation in this gene.

A Historical Geography Of The Bayswater Foreshore, Swan River, Susan Hames

Theses : Honours

This study examines the historical and present extents of native wetland-floodplain vegetation along the Swan River foreshore in the City of Bayswater, within the Perth metropolitan area. As a geographical history of native vegetation it is largely concerned with the contribution cultural values and modifications have made to ecological changes in foreshore biodiversity and the sustainability of the ecosystem. Adopted into the urban psyche, the Swan River forms a central artery in the cultural landscape and natural ecosystem; evocative and practical in combination. However, the contemporary foreshore is a modified environment with native vegetation, in terms of biodiversity and land …

Imagining The Performance Zone: Overcoming Ambiguity In Consumer Based Electronic Performance Support Systems, Jason Simons

Theses : Honours

The locus of performance support implementation was once the domain of large corporations where its principles offered an attractive alternative to traditional methods of training within the scope of contemporary business practices. Due to economies of scale the large corporations were able to build effective performance support through the precise identification of the PERFORMANCE ZONE. This zone is created through the defining of the three attributes of performance, 1) the nature of the worker, 2) the nature of the task, and 3) the type and amount of support needed. lncreasingly the principles of performance-centred design have been adopted within diverse …

The Reporting Of The Tampa Incident In Australian And Norwegian Newspapers, Lene Sjobrend

Theses : Honours

The M/S Tampa in August 2001 was turned by the Australian government into a tool to fight the increasing numbers of boat people heading for Australia. But more importantly, it was a fight to win back votes before the upcoming federal election. Also in Norway an election was imminent, and even though the incident did not become an important part of the Norwegian election campaign, it played a role in Norway's involvement in the case. The media has a tendency to listen to authoritative voices, which can make the media a victim of political spin. Since the governments in Norway …

Social Integration Of Older Immigrants In 21st Century America, Janet Wilmoth

Center for Policy Research

There are various reasons for the burgeoning interest in detailed research into the determinants of social well-being among older immigrants in this country. As a result of shifting federal government policies, the total volume of immigrants has increased significantly, the countries from which they migrate have changed, and more immigrant families have brought their parents into the United States than ever before. Consequently, the older adult population is becoming more diverse due in part to the aging-in-place of younger immigrants and an increasing number of immigrants who are older upon arrival in the United States. These trends create challenges for …

Duration Data From The National Long-Term Care Survey: Foundation For A Dynamic Multiple-Indicator Model Of Adl Dependency, James N. Laditka, Douglas A. Wolf

Center for Policy Research

This report describes preparation of data from the National Long-Term Care Survey (NLTCS) fur use in a dynamic multiple-indicator model of dependency in Activities of Daily Living (ADLs). The data set described makes use of all functional status information available across four NLTCS waves for six ADLs, including information from screening interviews, detailed interviews in the community, and institutional interviews. Importantly, it also captures all available information elicited from respondents about the *duration* of any impairment in these ADLs. The data was prepared as described in this report to enable the calculation of improved estimates of the probabilities that an …

Welfare State Expenditures And The Distribution Of Child Opportunities, Irwin Garfinkel, Lee Rainwater, Timothy M. Smeeding

Center for Policy Research

This paper estimates the redistributive effects of welfare state expenditures on social and economic disparities in the economic well-being of citizens in ten nations. Data from the Organization for Economic Cooperation and Development (OECD) and other sources for cash and non-cash social welfare benefits (health and education benefits from third parties) are used to describe differences in the size and nature of welfare states and their distributional effects. The OECD data are combined with micro data on household incomes from the Luxembourg Income Study (LIS) both to estimate the redistributive effects of the expenditures and taxes and to construct measures …

Taxes, Deadweight Loss And Intertemporal Female Labor Supply: Evidence From Panel Data, Anil Kumar

Center for Policy Research

Very few existing studies have estimated female labor supply elasticities using a U.S. panel data set, although cross-sectional studies abound. Also, most existing studies have done so in a static framework. I make an attempt to fill the gap in this literature by estimating a lifecycle-consistent specification with taxes, in a limited dependent variable framework, on a panel of married females from the PSID. Both parametric random effects and semi parametric fixed effects methods are applied. I find evidence of larger substitution effects than found in female labor supply literature with taxes, suggesting considerable distortionary effects from income taxation. The …

How Much More Does A Disadvantaged Student Cost?, William D. Duncombe, John Yinger

Center for Policy Research

This paper provides a guide to statistically based methods for estimating the extra costs of educating disadvantaged students, shows how these methods are related, and compares state aid programs that account for these costs in different ways. We show how pupil weights, which are included in many state programs, can be estimated from an education cost equation, which many scholars use to obtain an education cost index, and we devise a method to estimate pupil weights directly. Using data from New York, we show that the distribution of state aid is similar with statistically based pupil weights and an educational …

Maternal Employment And Adolescent Self-Care, Leonard M. Lopoo

Center for Policy Research

Mounting evidence shows that self-care produces deleterious consequences for adolescents in the U.S. Since descriptive evidence suggests that maternal employment is the primary explanation for adolescent self-care, maternal employment, it is frequently argued, is harming children. Heretofore, very little empirical research has actually investigated the impact of maternal employment on adolescent self-care, however, calling into question this assertion. This paper aims to fill this gap. The author uses the National Education Longitudinal Survey of 1988 supplemented by the National Longitudinal Survey of Youth-1979 to estimate the relationship between maternal employment and adolescent self-care. Unlike prior research, the author employs a …

Electrospinning As A Processing Method For Electroactive Polymers And Composites, Kristin Joy Pawlowski

Theses and Dissertations

Electrospinning was examined for its potential to create functional materials. Three distinct electroactive materials were electrospun into fibers and fiber mats and then characterized with the intent of determining their utility in aerospace and biomedical applications such as micro-air vehicles and the cardiovascular system. Electrospun Graft Elastomers demonstrated potential as actuators, as electromechanical strain testing showed comparable response to the film form of this material. Further improvement of electroactive response was realized with high dielectric inclusions and fiber orientation. Electrospin processing imparted piezoelectric properties to the fibers of poly(vinylidene fluoride). Differential scanning calorimetry and infrared spectroscopy indicated a degree of …

Gender And Ethnic Differences In Perceived Stress As A Predictor Of Smoking Behaviors In Rural Adolescents, Lashanda R. Jones

Theses and Dissertations

Cross-sectional and longitudinal analyses were conducted to examine the impact of perceived stress on current and future smoking behaviors of rural Virginia middle school students. Data were analyzed for 685 sixth grade students and 554 seventh grade students. Sixth grade students were 52% male, 53% Caucasian American (CA), and 47% African American (AA). For 7th graders, the sample was 53% female and 56% CA (44% AA). Of the 685 sixth grade students, 7% reported that they had smoked cigarettes at least once during the past 30 days (n=46,63% male and 67% CA). By the 7th grade, the percentage of smokers …

Rabies In Virginia, 1989-2003: With Particular Attention To Animals, Geographic Distribution, And Virus Variant, William Andrew Holzgrefe

Theses and Dissertations

Objectives: The description of the raccoon rabies epizootic in Virginia over fifteen years (1989-2003). Methods: Using simple statistical methods and a geographic information system (GIS)-based approach, and fifteen years worth of animal surveillance data, the progress of this epizootic has been charted in terms of the geographic spread of the disease, the major animal species affected by the disease and its spread, and the exposure and risk to humans and livestock animals presented by the expansion of the geographic range. Results: The resulting descriptive study illustrates the eastward expansion of the epizootic, the mushrooming of the disease in the northern …

Molecular Characterization Of Immunoglobins A, G, And M Heavy Chains In The Atlantic Bottlenose Dolphin, Tursiops Truncatus, Holly Ann Gefroh

MUSC Theses and Dissertations

The dolphin immune system is not well characterized, unlike the human and mouse immune systems. As a sentinel species of the marine ecosystem, an understanding of the dolphin immune system will not only contribute to conservation and management of the species, but also contribute to an understanding of the status of the marine ecosystem. cDNA sequences encoding IgA and IgG heavy chains and IgM transmembrane segment of the Atlantic bottlenose dolphin, Tursiops truncatus, were obtained using a combination of reserve transcription of mRNA, PCR amplification using degenerate primers, and 3' and VH-FR3 anchored 5' RACE. Analysis of dolphin γ gene …

Dis-Patch: Practice As. . . Practice And Research, Jonathan Mustard, Chrissie Parrott

Creative Connections Symposium @ BEAP2004 September 4, 2004

Dis-Patch is the title of a dance work that was partly the outcome of research into ways in which movement in space might successfully correlate to the parameters of sound. The process of making the work in workshops, rehearsals and performance both altered our view of, and added to the background research. It became evident in this process that certain outcomes, whilst alien to musically conventional ears, were nevertheless valid and interesting sonic translations of the choreography. The performance demonstrated how issues within and between disciplines can be re-problematised through the creative and innovative use of technology. It is our …

Lego Mindstorms As A Training Tool For Software Development Methodology In Multimedia Education., Elias Wyber

Creative Connections Symposium @ BEAP2004 September 4, 2004

This paper outlines an approach to educating multimedia practitioners utilizing Lego MindStorms® which evolved out of a desire to bridge the technical and aesthetic worldviews. The approach focuses on three aspects of the development process. First, it examines the linguistic model of code production. In order to convey the act of writing code as a linguistic task, the students are introduced to several aspects of linguistic theory, with examples illustrating their application in spoken, programmed and Lego MindStorms® based languages. The second area of focus is object theory. Adopting a similar approach to the previous section, but giving only Lego …

Phillip Adams, Nanette Hassall

Creative Connections Symposium @ BEAP2004 September 4, 2004

This paper explores the importance of narrative in Phillip Adams’ work. Despite the fact that he is seen by the critics as a member of the ‘post moderns’ in dance in Australia there are significant ways in which we see him depart from the traditional understandings of those terms in order to develop a more idiosyncratic and personal style.

Basic Communication Course Annual

Now 16 years old, the Basic Communication Course Annual continues to hold a unique and instrumental status among peer communication journals. Notably, the Annual is the only national communication journal devoted to research and scholarship pertaining to the basic communication course. What started as an infant in 1988 has grown into a bright young-adult with an admirable sense of self.

The success of the Annual is entirely attributable to the community of scholars who have supported the journal over the years. All of us should be thankful for the leadership provided by the previous editors: Deanna Sellnow, Craig Newburger, and …

Bias In The Evaluation Process: Influences Of Speaker Order, Speaker Quality, And Gender On Rater Error In The Performance Based Course, Paul D. Turman, Matthew H. Barton

Basic Communication Course Annual

This study examines how variations in speaker order increase the potential for rater error in the performance based course. Seventy-six undergraduate raters were randomly assigned to one of eight treatment groups and asked to grade eight-week training course. Speaker order and presentation quality varied across groups and an ANOVA was used to examine significant differences across rater assessments, feedback quality and rater gender. Significant main effects were identified in each of the eight treatment groups suggesting that speaker order influenced rater scoring.

Written Speech Feedback In The Basic Communication Course: Are Instructors Too Polite?, Dana L. Reynolds, Stephen K. Hunt, Cheri J. Simonds, Craig W. Cutbirth

Basic Communication Course Annual

The present study investigates written performance feedback through the lens of politeness theory. Study 1 examined the types of comments instructors offer to students when they provide written feedback on speeches as well as the relationship between these comments and students' grades.

Results demonstrate that instructors used an overabundance of positive politeness messages and virtually no negative politeness messages. Students who received a higher grade were more likely to receive fewer face threats and more positive politeness messages than those students' who received a lower grade. The results also suggest that instructors are more willing to threaten a students' negative …
