Statistical Estimation Of Strain Energy Release Rate Of Delaminated Composites, Rajesh Vijayaraghavan

Graduate Theses, Dissertations, and Problem Reports (ETD)

An improved two-sublaminate model based on first-order shear deformation theory is implemented in a general-purpose finite element software (ANSYS) to study delaminated composite plates. Double cantilever beam and end-notched flexure models of unidirectional and multidirectional composite plates with mid-plane and offset delaminations are analyzed. The total strain energy release rate and the mode-I, mode-II and mode-III components are evaluated using a plate-theory-based crack-closure technique.;The effects of variation of material properties, ply thickness, fiber orientation, coefficient of friction between the crack surfaces, finite element mesh density and virtual crack-closure length and applied load on the mixed-mode strain energy release rates are …

Efficient Simulation Of Communication Systems On A Desktop Grid, Raja Sekhar Katuri

Graduate Theses, Dissertations, and Problem Reports (ETD)

Simulation is an important part of the design cycle of modern communication systems. As communication systems grow more sophisticated, the computational burden of these simulations can become excessive. The need to rapidly bring systems to market generally precludes the use of a single computer, and drives a demand for parallel computation. While this demand could be satisfied by the development of dedicated infrastructure, a more efficient option is to harness the unused computational cycles of underutilized desktop computers located throughout the organization.;In this thesis, a new paradigm for parallelizing communication simulations is proposed and developed. A desktop grid is created …

The Smith-Mundt Act's Ban On Domestic Propaganda: An Analysis Of The Cold War Statute Limiting Access To Public Diplomacy, Edward L. Carter, Allen W. Palmer

Faculty Publications

For more than fifty years, the U.S. Code has authorized the federal government to disseminate messages about America to international audiences. For at least thirty years, federal law has also prohibited those international propaganda messages from being disseminated within the United States. Given the realities of the acceleration and dispersion of information flow across international borders in the twenty-first century, a ban on dissemination of information that is tied to geographic boundaries raises both practical and policy issues. The domestic dissemination ban may have outlived its usefulness and relevance. Further, futile enforcement of the statute contradicts general U.S. policy promoting …

Variability In Selecting Lateral Cephalometric Landmarks In Two Cbct Image Modes, Dana Nguyen

Loma Linda University Electronic Theses, Dissertations & Projects

Purpose: The purpose of this study was to determine the variability of lateral cephalometric landmark selection in two cone beam computed tomography (CBCT) lateral cephalometric simulations: 1) a mean projection image (MPI) and 2) a serial sagittal slice image (SSSI).

Methods: A MPI is a two-dimensional (2D) image obtained from the NewTom 3G^TM CBCT that resembles the conventional lateral cephalogram. A SSSI is a 2D image also obtained from CBCT data, but is created by superimposing a series of selected thin sagittal slices containing the required cephalometric landmarks. This study compared the Ricketts and Steiner analysis of the MPI …

The Qualitative Report

This inquiry applied an innovative sociocultural framework to examine transformations in preservice teachers’ professional development as they worked with children at-risk in a summer literacy camp. The camp incorporated a community of practice model in which teams of master’s and doctoral students mentored small groups of preservice teachers. The study examined preservice teachers ’ learning following Rogoff’s (1995, 1997) notions of the personal, interpersonal, and community planes of analysis. The research also employed a postmodernist crystallization imagery to capture multiple perspectives on the preservice teachers’ growth. The study assigns importance to the contextual dimensions in which learning takes place, and …

Student Scholarship

The purpose of this research study was to investigate how practitioners' of the durable consumer goods industry make resource allocation decisions in technical innovation, in an industry shaped by high uncertainty and low barriers to entry. Few studies have been conducted that generated qualitative data that allowed for comparisons between prescriptive models and the actual lived-world experiences of practitioners. During the investigation we conducted interviews with executives of the industry that allowed us to better understand how practitioners derived at decisions and why certain organizations were able to innovate more successfully than others. This analysis leveraged the theories of the …

The Impact Of Organization Destruction On Social Capital Value, R. Drew Sellers

Student Scholarship

This paper links social capital dynamics and value with organization destruction. It produces the finding that organizational destruction may in some cases increase the value of social capital. A key theoretical contribution of this study is extending the metaphor of social capital to encompass asset recoverability. Based upon cases studies of 15 individuals who lived through the destruction of Arthur Andersen, this paper examines the persistence and value of an individual's social capital when an organization destructs. It explores the question, "Is the value of an individual's investment in organization-specific social capital a recoverable asset post-destruction?" Interviews with Andersen alumni …

Culturally Adapted Mental Health Interventions: A Meta-Analytic Review, Timothy B. Smith, Derek Griner

Faculty Publications

There is a pressing need to enhance the availability and quality of mental health services provided to persons from historically disadvantaged racial and ethnic groups. Many previous authors have advocated that traditional mental health treatments be modified to better match clients? cultural contexts. Numerous studies evaluating culturally adapted interventions have appeared, and the present study used meta-analytic methodology to summarize these data. Across 76 studies the resulting random effects weighted average effect size was d = .45, indicating a moderately strong benefit of culturally adapted interventions. Interventions targeted to a specific cultural group were four times more effective than interventions …

Autoethnographical Inquiry Into Joyful Teaching: Explorations With National Teachers Of The Year, Camille Lowe Shirah

College of Graduate Studies: Theses & Dissertations

Presently, schools in the United States are held within the tight grip of No Child Left Behind, signed into law in 2001. Since accountability is high, some teachers experience burnout and succumb to disenchantment with the profession (Palmer, 1998). Others find their commitments to education so diminished that they abuse their position and fail terribly in their charge to educate our youth. There are some, however, who find ways to continually affirm and sustain their commitments to education. Within the following autoethnographical inquiry, the lives of three National Teachers of the Year are examined with the hope of finding out …

Query-Based Watermarking For Xml Data, Xuan Zhou, Hwee Hwa Pang, Kian-Lee Tan

Research Collection School Of Computing and Information Systems

As increasing amount of XML data is exchanged over the internet, copyright protection of this type of data is becoming an important requirement for many applications. In this paper, we introduce a rights protection scheme for XML data based on digital watermarking. One of the main challenges for watermarking XML data is that the data could be easily reorganized by an adversary in an attempt to destroy any embedded watermark. To overcome it, we propose a query-based watermarking scheme, which creates queries to identify available watermarking capacity, such that watermarks could be recovered from reorganized data through query rewriting. The …

Implication Of Comprehensive Income Disclosure For Future Earnings And Analysts' Forecasts, Jong-Hag Choi, Yoonseok Zang

Research Collection School Of Accountancy

This paper examines the association of comprehensive income with subsequent period net income as well as analysts’ earnings forecasts. Our results support the notion that comprehensive income is incrementally useful in predicting subsequent period changes in net income. We also document that comprehensive income is associated with analysts’ earnings forecast revisions and forecast errors. The evidence is consistent with analysts’ failure to fully utilize the information disclosed in comprehensive income. The result suggests that analysts revise their year t+1’s forecast downward when comprehensive income is smaller than net income but they do not revise the forecast upward when comprehensive income …

The Association Between Earnings Quality And Regulatory Report Opinions In The Accounting Industry, Tracey Chunqi Zhang, Katherine Gunny

Research Collection School Of Accountancy

We compare the outcome of two different information systems – self regulation versus private sector regulation – in the accounting industry. Under the Sarbanes-Oxley Act, Public Company Accounting Oversight Board (PCAOB) inspections replaced American Institute of Certified Public Accountants (AICPA) peer reviews of auditors. Peer review opinions are useful with respect to decisions about hiring and firing of auditors (Hilary and Lennox, 2005); therefore, the question remains what are the benefits of incurring the cost to replace a selfregulatory system with a private regulatory agency. We examine the usefulness of these two information systems at distinguishing earnings quality at firms …

Escalation And De-Escalation Of Commitment To Information Systems Projects: Insights From An Approach-Avoidance Process Model, Gary Pan, Shan Ling Pan

Research Collection School Of Accountancy

We view escalation and de-escalation of commitment as processes involving recurring instances of approach-avoidance conflict. This paper outlines an approach-avoidance process model for describing and analyzing escalation and de-escalation of commitment in information systems projects. In the model, the sequential mapping of project events is integrated with a model of approach-avoidance conflict that identifies periods of gradual evolution at two separate levels of social analysis (project and work) that are punctuated by sudden, revolutionary periods of rapid change. By conceiving the processes of commitment escalation and de-escalation as sequences of events involving approach-avoidance conflicts, researchers may develop a deeper understanding …

Reiterated Commemoration: Hiroshima As National Trauma, Hiro Saito

Research Collection School of Social Sciences

This article examines historical transformations of Japanese collective memory of the atomic bombing of Hiroshima by utilizing a theoretical framework that combines a model of reiterated problem solving and a theory of cultural trauma. I illustrate how the event of the nuclear fallout in March 1954 allowed actors to consolidate previously fragmented commemorative practices into a master frame to define the postwar Japanese identity in terms of transnational commemoration of "Hiroshima." I also show that nationalization of trauma of "Hiroshima" involved a shift from pity to sympathy in structures of feeling about the event. This historical study suggests that a …

Insider Trading And Voluntary Disclosures, Qiang Cheng, Kin Lo

Research Collection School Of Accountancy

We hypothesize that insiders strategically choose disclosure policies and the timing of their equity trades to maximize trading profits, subject to the litigation costs associated with disclosure and insider trading. Accounting for endogeneity between disclosures and trading, we find that when managers plan to purchase shares, they increase the number of bad news forecasts to reduce the purchase price. In addition, this relation is stronger for trades initiated by chief executive officers than for those initiated by other executives. Confirming this strategic behavior, we find that managers successfully time their trades around bad news forecasts, buying fewer shares beforehand and …

After The Catastrophe: Disaster Relief For Hospitals, Elizabeth Weeks Leonard

Scholarly Works

Disaster planning for health care providers following the September 11, 2001, terrorist attacks and, more recently, Hurricane Katrina, focuses on preparing hospitals and other emergency services to respond to victims' medical needs. But little attention has been paid to the challenges that providers would face resuming normal operations after responding to the catastrophe. A large-scale catastrophe could create unprecedented demand for health care and emergency services. Hospitals already struggle to fulfill the high demand for and high costs of emergency care. Following a major disaster, hospitals would face additional financial challenges. Strained capacity and financial reserves, may force hospitals to …

Federal Court Self-Preservation And Terri Schiavo, Jack M. Beermann

Faculty Scholarship

If the federal court in Florida had granted preliminary relief to allow itself more time to consider the constitutional claims that Terri Schiavo's parents brought on her behalf, and if, as expected, those claims were ultimately rejected, the federal court would have been placed in the unenviable position of having to be the institution that made the final decision to terminate Terri Schiavo's feeding and other treatment. Although I have no way of knowing whether this fact, which has not been noted in the commentary,' actually entered into the mind of any of the federal judges who considered the case, …

Teaching Music Theory In The Traditional Wind Band Rehearsal: A Rationale, Survey Of Materials, And Recommendations, Eric Lynn Harris

Dissertations

Band programs in today’s schools are facing pressures unheard of in the early days of the public school band movement. While budget limitations have always been a part of the public school dilemma, never before have directors been forced to fight so hard for the very existence of their programs. School administrators facing district, state, and federal testing pressures are spending more and more of the annual budget in an attempt to raise test scores. This means programs in the arts and even athletics are being greatly reduced (and in some cases eliminated) in school systems across the country. To …

On The Use Of Modis Evi To Assess Gross Primary Productivity Of North American Ecosystems, Daniel A. Sims, Abdullah Rahman, Vicente D. Cordova, Bassil Z. El-Masri, Dennis D. Baldocchi, Lawrence B.

[1] Carbon flux models based on light use efficiency (LUE), such as the MOD17 algorithm, have proved difficult to parameterize because of uncertainties in the LUE term, which is usually estimated from meteorological variables available only at large spatial scales. In search of simpler models based entirely on remote‐sensing data, we examined direct relationships between the enhanced vegetation index (EVI) and gross primary productivity (GPP) measured at nine eddy covariance flux tower sites across North America. When data from the winter period of inactive photosynthesis were excluded, the overall relationship between EVI and tower GPP was better than that between …

The Importance Of Continuity In First Language Education For Learning A Second Language, Stephen M. Shepherd

Theses and Dissertations - UTB/UTPA

Scores from the Texas Reading Proficiency Tests in English (RPTE) for ninety-four Newcomer ESL students were analyzed to understand the differences between students who had attended school continuously and those who had discontinuity in their first language (LI) education in their home country. This research was performed in the Rio Grande Valley of South Texas, a few miles from the border with Mexico. The hypothesis is that students who have gaps in their L1 education will not learn to read as quickly in English as those who had none since the former are lacking cognitive skills which the latter already …

A Two-Stage Realized Volatility Approach To Estimation Of Diffusion Processes With Discrete Data, Peter C. B. Phillips, Jun Yu

Research Collection School Of Economics

This paper motivates and introduces a two-stage method of estimating diffusion processes based on discretely sampled observations. In the first stage we make use of the feasible central limit theory for realized volatility, as developed in [Jacod, J., 1994] and [Barndorff-Nielsen, O., Shephard, N., 2002], to provide a regression model for estimating the parameters in the diffusion function. In the second stage, the in-fill likelihood function is derived by means of the Girsanov theorem and then used to estimate the parameters in the drift function. Consistency and asymptotic distribution theory for these estimates are established in various contexts. The finite …
