Buccal Bone Changes Following Rapid Maxillary Expansion (Rmf), Long-Term Results, Elena S. Iacob

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this study was to use Cone Beam Computed Tomography (CBCT) images to quantitatively evaluate buccal bone changes of maxillary first premolar (P1), second premolar (P2) and first molar (M1) shortly after Rapid Maxillary Expansion (RME) and at the end of orthodontic treatment, as well as to evaluate the variables that may be associated with the short-term and long-term changes. Forty-seven consecutive patients (25 males and 22 females) with a mean age of 14.5years and who required RME as part of their orthodontic treatment and had pre-RME (T1) and post-RME (T2) CBCT images available were used for the …

Making A Connection Between Student Achievement, Teacher Accountability, And Quality Classroom Instruction, Kelli Ballard, Alan Bates

The Qualitative Report

The importance of standardized test results is becoming more prevalent in the structure of classroom instruction and the operation of schools throughout the nation due to pressure on educators and students from various levels of authority. This study looks at the relationship between classroom instruction and standardized test content and the effects this has on students, parents, and teachers. Seventeen fourth grade students, fourteen parents of fourth graders, and fifteen elementary teachers completed surveys. The study describes several positive and negative aspects to standardized tests, along with ideas of who is responsible for test performance. Standardized tests provide comparisons and …

Increased Myocardial Susceptibility To Repetitive Ischemia With High-Fat–Diet-Induced Obesity, Geeta D Thakker, Nikolaos G Frangogiannis, Pawel T Zymek, Saumya Sharma, Joe L Raya, Philip M Barger, Heinrich Taegtmeyer, Mark L Entman, Christie M Ballantyne

Faculty, Staff and Student Publications

Obesity and diabetes are frequently associated with cardiovascular disease. When a normal heart is subjected to brief/sublethal repetitive ischemia and reperfusion (I/R), adaptive responses are activated to preserve cardiac structure and function. These responses include but are not limited to alterations in cardiac metabolism, reduced calcium responsiveness, and induction of antioxidant enzymes. In a model of ischemic cardiomyopathy inducible by brief repetitive I/R, we hypothesized that dysregulation of these adaptive responses in diet-induced obese (DIO) mice would contribute to enhanced myocardial injury. DIO C57BL/6J mice were subjected to 15 min of daily repetitive I/R while under short-acting anesthesia, a protocol …

Coordinated Changes In Mrna Turnover, Translation, And Rna Processing Bodies In Bronchial Epithelial Cells Following Inflammatory Stimulation, Yuxin Zhai, Zhenping Zhong, Chyi-Ying A Chen, Zhenfang Xia, Ling Song, Michael R Blackburn, Ann-Bin Shyu

Faculty, Staff and Student Publications

Bronchial epithelial cells play a pivotal role in airway inflammation, but little is known about posttranscriptional regulation of mediator gene expression during the inflammatory response in these cells. Here, we show that activation of human bronchial epithelial BEAS-2B cells by proinflammatory cytokines interleukin-4 (IL-4) and tumor necrosis factor alpha (TNF-alpha) leads to an increase in the mRNA stability of the key chemokines monocyte chemotactic protein 1 and IL-8, an elevation of the global translation rate, an increase in the levels of several proteins critical for translation, and a reduction of microRNA-mediated translational repression. Moreover, using the BEAS-2B cell system and …

A Simple, Anatomically Based Correction To The Conventional Ankle Joint Center, Dustin A. Bruening, Ashlie N. Crewe, Frank L. Buczek

Faculty Publications

Background

Conventional motion analysis studies define the ankle joint center as the midpoint between the most medial and lateral aspects of the malleoli, yet research points toward a more distal joint center location. The purpose of this study was to develop and evaluate an anatomically based correction that would move the conventional ankle joint center to a more accurate location.

Methods

Lower extremity radiographs from 30 pediatric patients were analyzed retrospectively. An offset between the conventional and more accurate ankle joint centers was measured and correlated to other common anatomical measures based on conventional skin mounted marker positions. The best …

Bystanders' Reactions Towards Co-Punishment Events In The Taiwanese Military: Examining The Moderating Effects Of Organizational Norms, Shu-Cheng S. Chi, Hsin-Hsin Lo, Tsai Ming-Hong, Brian P. Niehoff

Research Collection School of Social Sciences

The present study examined bystanders' justice perceptions about co-punishment events. In a sample of 169 logistic officers in the Taiwanese military, responsibility attributions (i.e. liability attributed to co-punished persons) had a negative relationship with perceived harshness, and a positive relationship with perceived procedural justice. In addition, the effects of responsibility attributions on procedural justice were weaker if the person perceived stronger rather than weaker organizational norms of co-punishment.

Compared To What? A Comment On "A Robust Transformation Procedure For Interpreting Political Text" By Martin And Vanberg, Kenneth Benoit, Michael Laver

Research Collection School of Social Sciences

In “A Robust Transformation Procedure,” Martin and Vanberg (2007, hereafter MV) propose a new method for rescaling the raw virgin text scores produced by the “Wordscores” procedure of Laver, Benoit, and Garry (2003, hereafter LBG). Their alternative method addresses two deficiencies they argue exist with the transformation of virgin text scores proposed by LBG: First, that the LBG transformation is sensitive to the selection of virgin texts, and second, that it distorts the reference metric by failing to recover the original reference scores when reference texts are scored and transformed as if they were virgin texts. Their proposed alternative is …

Managerial Ownership, Corporate Monitoring And Audit Pricing, Soongsoo Han, Julia Higgs, Tony Kang

Research Collection School Of Accountancy

We study whether managerial ownership and corporate monitoring (board quality and analyst coverage) relate to audit pricing. Managerial ownership has been identified as a fraud risk factor under SAS 99. However, the role of ownership is not clear. Under an alignment view, high levels of stock ownership align management with shareholders. Under an entrenchment view, high levels of ownership may motivate management to be self interested. Corporate monitoring, as measured by analyst coverage and overall board quality (Gomper’s index), are associated with information quality. Audit pricing will be affected to the extent that auditors perceive monitoring as being relevant to …

Managerial Ownership And Firms' Information Environment, Soongsoo Han, Tony Kang, Gerald Lobo

Research Collection School Of Accountancy

We examine the relation between managerial stock ownership and the firm’s information environment. We focus on three dimensions of the information environment: total, public, and private information precision (Barron, Kim, Lim and Stevens 1998). Our results suggest that firms’ total and public information precision are positively related to managerial ownership. In contrast, there is no clear pattern in private information precision across different levels of managerial ownership. We also observe that managerial ownership has a greater impact on the firm’s public information environment after the implementation of Regulation Fair Disclosure, suggesting that the regulation was effective in improving the firms’ …

Ambiguous Optimistic Fair Exchange, Qiong Huang, Guomin Yang, Duncan S. Wong, Willy Susilo

Research Collection School Of Computing and Information Systems

Optimistic fair exchange (OFE) is a protocol for solving the problem of exchanging items or services in a fair manner between two parties, a signer and a verifier, with the help of an arbitrator which is called in only when a dispute happens between the two parties. In almost all the previous work on OFE, after obtaining a partial signature from the signer, the verifier can present it to others and show that the signer has indeed committed itself to something corresponding to the partial signature even prior to the completion of the transaction. In some scenarios, this capability given …

Chinese Visions Of World Order: Post-Hegemonic Or A New Hegemony?, William A. Callahan

Research Collection School of Social Sciences

Lately, there has been increasing interest among international relations (IR) scholars in Chinese thought, both as an alternative to Eurocentric IR, and because the PRC as an emerging power will soon have the institutional power to promote its view of the world. Rather than look for suitable Chinese parallels to "international," "security," or other mainstream concepts, this article will examine the concept of "Tianxia All-under-Heaven" to understand Chinese visions of world order. Tianxia is interesting both because it was key to the governance and self-understanding of over two millennia of Chinese empire, and also because discussion of Tianxia is becoming …

The Right To Silence Helps The Innocent: A Response To Critics, Alex Stein

Cardozo Law Review

This Article responds to the numerous critics of Daniel J Seidmann & Alex Stein, The Right to Silence Helps the Innocent: A Game-Theoretic Analysis of the Fifth Amendment Privilege, 114 HARV. L. REV. 430 (2000). Under Seidmann and Stein's theory, the right to silence protects innocents who find themselves unable to corroborate their self-exonerating accounts by verifiable evidence. Absent the right, guilty criminals would pool with innocents by making false self-exonerating statements. Factfinders would consequently discount the probative value of all uncorroborated exculpatory statements, at the expense of those innocents who cannot corroborate their true accounts. The right to …

Multiple Radar Data Merging In Hydro-Nexrad, Witold F. Krajewski, Bong Chul Seo, Anton Kruger, Piotr Domaszczynski, Gabriele Villarini, James A. Smith

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

The Hydro-NEXRAD merging algorithms include two options: (1) data-based merging; and (2) product-based merging. Data-based merging algorithm takes volume scan reflectivity data from all radars involved through preprocessing algorithm that performs volume data quality control, interpolates data to synchronize temporal scale between individual radars, and finally combines data onto a common geographic grid. Reflectivity values for a given location are assigned by a weighting function with respect to the distance from the radar. This single reflectivity field is then converted to rainfall amounts using a user-requested standard approach. In product-based merging algorithm reflectivity data from multiple radars are all converted …

On Step Sizes, Stochastic Shortest Paths, And Survival Probabilities In Reinforcement Learning, Abhijit Gosavi

Engineering Management and Systems Engineering Faculty Research & Creative Works

Reinforcement learning (RL) is a simulation-based technique useful in solving Markov decision processes if their transition probabilities are not easily obtainable or if the problems have a very large number of states. We present an empirical study of (i) the effect of step-sizes (learning rules) in the convergence of RL algorithms, (ii) stochastic shortest paths in solving average reward problems via RL, and (iii) the notion of survival probabilities (downside risk) in RL. We also study the impact of step sizes when function approximation is combined with RL. Our experiments yield some interesting insights that will be useful in practice …

Proper Orthogonal Decomposition In The Generation Of Reduced Order Models For Interconnects, Wu Zhong Lin, Yao Jiang Zhang, Er Ping Li

Electrical and Computer Engineering Faculty Research & Creative Works

In this paper, reduced order models are generated using the technique of proper orthogonal decomposition (POD), also known as Karhunen-Loève decomposition (KLD) for the simulations of interconnect problems. Model order reduction is achieved by projecting the state-space of the original problems onto a subspace spanned by a few numbers of proper orthogonal modes (POMs) extracted by the POD procedure from an ensemble of system responses at a series of selected frequencies. the proper orthogonal values (POVs) corresponding to the POMs indicate the level of the importance of each POM and provide a guidance for the number of POMs to be …

Time-Domain Receiver Design For Mimo Underwater Acoustic Communications, Jun Tao, Yahong Rosa Zheng, Chengshan Xiao, T. C. Yang, Wen Bin Yang

Electrical and Computer Engineering Faculty Research & Creative Works

In this paper, we propose a time-domain receiver design scheme for high data rate single carrier multiple-input, multiple-output (MIMO) underwater acoustic communications. in this scheme, each received packet is artificially partitioned into blocks for processing. the MIMO channel is initially estimated using training blocks at the front of transmitted packets from all transducers. with the estimated MIMO channel, one data block following the training blocks is equalized. the phase rotation in the equalized data block is compensated by a group-wise phase correction operation, before symbol detection. the newly detected data block along with K - 1 previous data (or pilot) …

Advent Of Denial Of Death In Children's Literature, Marvin Tyler Sasser

College of Graduate Studies: Theses & Dissertations

After creating and sustaining highly Romanticized notions of childhood, society begins to protect children from the dangers that supposedly exist exclusively in adult reality, particularly death. Taking into consideration society's attitude towards childhood, this thesis closely examines the different ways in which authors deny death in children's literature. Nineteenth-century authors often use enchantment to create ways for children to survive in an otherwise cruel and deadly Victorian world. As social issues slowly begin to improve, death in children's literature moves away from an event that without magic cannot be ignored, to an occurrence far less likely to happen during childhood. …

"As-Yet-Still-Forgiven Past": Dylan Thomas And Nostalgia, David Bradley Bailey

College of Graduate Studies: Theses & Dissertations

Dylan Thomas exhibited a variety of nostalgic influences within his poetry. A careful study of his life will reveal a nostalgia that evolved from adolescent musings upon an ideal past, to a self-destructive urge to return to innocence through death. Thomas incorporates a variety of historical influences within this nostalgia, but his primary influence is ultimately his own tormented past. This study not only focuses on the personal nostalgia of one man, but the variety of ways nostalgia can affect people, history and society as sociological force.
