Information Sharing: Hackers Vs Law Enforcement, David P. Biros, Mark Weiser, Jim Burkman, Jason Nichols

Australian Information Warfare and Security Conference

The fields of information assurance and digital forensics continue to grow in both importance and complexity, spurred on by rapid advancement in digital crime. Contemporary law enforcement professionals facing such issues quickly discover that they cannot be successful while operating in a vacuum and turn to colleagues for assistance. However, there is a clear need for greater IT-based knowledge sharing capabilities amongst law enforcement organizations; an environment historically typified by a silo mentality. A number of efforts have attempted to provide such capabilities, only to be met with limited enthusiasm and difficulties in sustaining continued use. Conversely, the hacker community …

SWARM has been deployed on six major corridors and operates during the morning and afternoon peak hours. This report presents results of a "before" and "after" evaluation of the performance of two freeway corridors as part of ongoing efforts to measure the benefits of the new SWARM system, as compared to the pre-timed system. The study benefited from using the existing regional data, surveillance and communications infrastructure in addition to a …

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 …

Note: this full-text download is the accepted and/or submitted version of this work.

Social movements have been viewed as vehicles through which the concerns of poor and marginalized groups are given greater visibility within civil society, lauded for being the means to achieve local empowerment and citizen activism, and seen as essential in holding the state to account and constituting a grassroots mechanism for promoting democracy. However, within development studies little attention has been paid to understanding how social movements can affect trajectories of development and rural livelihood in given spaces, and how these effects are related to movements' internal …

Are Delay Discounting, Probability Discounting, Time Perception, And Time Perspective Related? A Cross-Cultural Study Among Latino And White American Students, Ana Amelia L. Baumann Neves

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The present study aimed to evaluate (a) the extent to which different impulsivity measures would be related to each other and to a risk taking measure, (b) the extent to which impulsivity, risk taking, time perception and time perspective are related to each other, and (c) the extent to which these processes differ in Latino and White American students. Experiment I was conducted at Utah State University. One hundred and forty-three participants were exposed to the delay discounting, probability discounting and temporal bisection procedures, and answered the Barratt Impulsiveness Scale (BIS-11) and the Zimbardo Time Perspective Inventory (ZTPI). Results showed …

Forensic And Anti-Forensic Techniques For Object Linking And Embedding 2 (Ole2)-Formatted Documents, Jason M. Daniels

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Common office documents provide significant opportunity for forensic and anti-forensic work. The Object Linking and Embedding 2 (OLE2) specification used primarily by Microsoft’s Office Suite contains unused or dead space regions that can be over written to hide covert channels of communication. This thesis describes a technique to detect those covert channels and also describes a different method of encoding that lowers the probability of detection.

The algorithm developed, called OleDetection, is based on the use of kurtosis and byte frequency distribution statistics to accurately identify OLE2 documents with covert channels. OleDetection is able to correctly identify 99.97 percent of …

Application Of Structural Control For Civil Engineering Structures, Abdollah Shafieezadeh

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study presents the application of control methods in seismic mitigation of structural responses. The study consists of two parts. In the first section, fractional order filters are utilized to enhance the performance of the conventional LQR method for optimal robust control of a simple civil structure. The introduced filters modify the state variables fed back to the constant gain controller. Four combinations of fractional order filter and LQR are considered and optimized based on a new performance criterion defined in the paper. Introducing fractional order filters is shown to improve the results considerably for both the artificially generated ground …

Synthesis And Characterization Of Lactose-Amines With Respect To Oil-In-Water Emulsion Stability, Nidhi Garg

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Fatty amines (hexadecyl-amine) can be esterified to lactose via Schiff-base formation at temperatures of 60° C. Extending the time of the reaction results in a darker colored product due to the Maillard reaction. Due to the amphiphilic properties of the lactose-amines, the emulsion stabilization characteristics were investigated.

In this study, synthesis of lactose-amines was done at four different heating and cooling cycles from 4 to 24 hours. Lactose-amines processed for 24 hours and 12 hours of constant heating and cooling cycles are named as 24H and 12H, respectively. Lactose-amines 4H and 8H were processed for 4 and 8 hours of …

The Effect Of Teacher Education Level, Teaching Experience, And Teaching Behaviors On Student Science Achievement, Danhui Zhang

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Previous literature leaves us unanswered questions about whether teaching behaviors mediate the relationship between teacher education level and experience with student science achievement. This study examined this question with 655 students from sixth to eighth grade and their 12 science teachers. Student science achievements were measured at the beginning and end of 2006-2007 school year. Given the cluster sampling of students nested in classrooms, which are nested in teachers, a two-level multilevel model was employed to disentangle the effects from teacher-level and student-level factors. Several findings were discovered in this study. Science teachers possessing of advanced degrees in science or …

The purpose of this study was to assess the influence of program requirements on employability of Utah State University's (USU) marriage and family therapy (MFT) program graduates, the training and employability of USU MFT graduates, and whether or not there is anything that sets these graduates apart from graduates of other MFT programs. Nineteen employers participated in this study. Twelve of these employers were known to have hired USU MFT graduates as the graduates' first employment post-graduation, and seven of the participants were considered potential employers: those who could hire MFTs in the future. Questions were asked to these participants …

Gene Expression Analysis Of Immobilized Saccharomyces Cerevisiae, Ryan Michael Summers

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Immobilization is an effective method to increase ethanol production, as proven by previous research. Results almost exclusively demonstrate an increase in ethanol production by and decrease in reproduction rate of immobilized Saccharomyces cerevisiae cells. Recently, research has been conducted to determine the cause of this change. The extreme variance in results due to lack of technology makes it difficult to determine the cellular changes induced by immobilization. With the advent of new technology, specifically gene expression analysis, the RNA content of cells can be easily and rapidly analyzed.

S. cerevisiae cells were immobilized in 3% (w/v) calcium alginate beads and …

Rank-Data Distribution Method (R-D Method) For Daily Time-Series Bayesian Networks And Total Maximum Daily Load Estimation, Joon-Hee Lee

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Daily time series-based models are required to estimate the higher frequency fluctuations of nutrient loads and concentrations. Some mechanistic mathematical models can provide daily time series outputs of nutrient concentrations but it is difficult to incorporate non-numerical data, such as management scenarios, to mechanistic mathematical models. Bayesian networks (BNs) were designed to accept and process inputs of varied types of both numerical and non-numerical inputs.

A Rank-Data distribution method (R-D method) was developed to provide large time series of daily predicted flows and Total Phosphorus (TP) loads to BNs driving daily time series estimates of T-P concentrations into Hyrum and …

The Evaluation Of Synchronous Online Tutoring For Students At-Risk Of Reading Failure, Eleazar Vasquez Iii

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Both legislative mandates such as those of No Child Left Behind (NCLB), and developments in the provision of reading instruction such as Response to Intervention (RTI), increase the demand for high quality tutoring services. However, the U.S. Department of Education and state officials report that access to intensive supplemental tutoring may be limited in rural and urban areas due to limited availability of qualified providers. Online tutoring may be one way to provide supplemental reading instruction to students identified as at-risk of reading failure.

Researchers have focused on distance education since the 1920s. The authors of recent meta-analyses report near …

Measuring And Modeling Of Plant Root Uptake Of Organic Chemicals, Erik Dettenmaier

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Determining the root uptake of xenobiotic organic chemicals into plants is critical for assessing the human and ecological health risks associated with the consumption of plants growing in contaminated environments. Root uptake of xenobiotic organics occurs passively in conjunction with transpiration and the transport from root to shoot is ultimately controlled by passage through one or more lipid root membranes. The transpiration stream concentration factor (TSCF), the ratio between the concentration of a chemical in the xylem to that in the solution used by the roots, is used to describe the relative ability of an organic chemical to be passively …

Angles-Only Navigation For Autonomous Orbital Rendezvous, David Charles Woffinden

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The proposed thesis of this dissertation has both a practical element and theoretical component which aim to answer key questions related to the use of angles-only navigation for autonomous orbital rendezvous. The first and fundamental principle to this work argues that an angles-only navigation filter can determine the relative position and orientation (pose) between two spacecraft to perform the necessary maneuvers and close proximity operations for autonomous orbital rendezvous. Second, the implementation of angles-only navigation for on-orbit applications is looked upon with skeptical eyes because of its perceived limitation of determining the relative range between two vehicles. This assumed, yet …

Generalized Event Tree Algorithm And Software For Dam Safety Risk Analysis, Anurag Srivastava

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Event tree analysis is a most commonly used method in dam safety risk analysis modeling. Available software tools for performing event tree analyses lack the flexibility to efficiently address many important factors in dam safety risk analysis. As a result of these practical limitations, spreadsheets have been used, sometimes including Visual Basic macros, to perform these analyses. However, this approach lacks generality and can require significant effort to apply to a specific dam or to modify the event tree structure. In response to these limitations, here a generalized event tree analysis tool, DAMRAE (DAM safety Risk Analysis Engine), has been …

Application Of Resiliency Theory And Adaptive Cycles As A Framework For Evaluating Change In Amenity-Transition Communities, Scott L. Hoffmann

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In recent decades, many rural, natural resource-dependent communities have experienced ubiquitous and oftentimes substantial economic decline due to downturns in their commodity-oriented industries. In spite of this, communities with access to varying forms of natural capital have experienced an upsurge in activities such as recreation, tourism, second home growth, and retirement in-migration. If managed properly, amenity-oriented development has potential to reverse economic decline by attracting tourists, entrepreneurs, younger and more educated workers, and retirees, and may ultimately generate economic diversification, local growth, and an improved quality of life for residents. While there are literally thousands of potential measures of well-being, …

The introduction gives an overview of the contemporary significance of social movements for rural development dynamics in the region, and of the principal insights of the section papers and the broader research program of which they were a part. This significance varies as an effect of two distinct and uneven geographies: the geography of social movements themselves and the geography of the rural political economy. The effects that movements have on …

Optimization Of A Hardware/Software Coprocessing Platform For Eeg Eyeblink Detection And Removal, Matthew Alan Chaudhuri

Theses

The feasibility of implementing a real-time system for removing eyeblink artifacts from electroencephalogram (EEG) recordings utilizing a hardware/software coprocessing platform was investigated. A software based wavelet and independent component analysis (ICA) eyeblink detection and removal process was extended to enable variation in its processing parameters. Exploiting the efficiency of hardware and the reconfigurability of software, it was ported to a field programmable gate array (FPGA) development platform which was found to be capable of implementing the revised algorithm, although not in real-time. The implemented hardware and software solution was applied to a collection of both simulated and clinically acquired EEG …
