Methods for collecting dietary intakes of free-living individuals have been studied over the past century and there are many limitations. Collection of dietary intakes from individuals is best done in food diary format and researchers have investigated both written and photographic records. The purpose of this study was to add to the body of literature on studies of collecting dietary intakes by comparing written food records (FR), digital food records (DP), written and digital food records combined (FRDP), and digital food records with limited documentation (DPR) to one another and to a known, criterion value. This study included 50 Registered …

Assessing Data Quality In A Sensor Network For Environmental Monitoring, Gesuri Ramirez

Open Access Theses & Dissertations

Assessing the quality of sensor data in environmental monitoring applications is important, as erroneous readings produced by malfunctioning sensors, calibration drift, and problematic climatic conditions, such as icing or dust, are common.Traditional data quality checking and correction is a painstaking manual process, so the development of automatic systems for this task is highly desirable.

This study investigates machine learning methods to identify and clean incorrect data from a real-world environmental sensor network, the Jornada Experimental Range, located in Southern New Mexico. We evaluated several learning algorithms and data replacement schemes, and developed a method to identify the problematic sensor. The …

Impact Of Science And Engineering Graduates On Key Economic Indicators, Nathaniel V. Robinson

Open Access Theses & Dissertations

There are clear trends in the USA with regard to a stagnant growth in science and engineering, particularly engineering, and in greater contrast when considered per capita. Meanwhile certain Asian counties, such as China and Taiwan, have experienced growth in science and engineering graduates beyond mere population growth. This has caught the eye of alarmists and so discussions have ensued over offshoring, national security, economic loss and future impact in the United States. Alarmists and proponents of policies promoting more science, engineering and math have pointed out the trends in overseas growth and US offshoring with a flurry of statistics …

Open Access Theses & Dissertations

Self-reacting friction stir welding is the latest FSW tool configuration developed, it employs two shoulders--one on top and one on the bottom of the workpiece-- this tool configuration offers many advantages over conventional welding techniques. However, the current lack of information and specifications limits its understanding and application. This investigation analyzed the effect of process parameters on temperature distribution, microstructure evolution, and final mechanical properties of 6061-T651 SR-FS welds. A factorial experiment was carried out, in which three-process parameters were analyzed--rotational speed, travel speed, and tool plunge force-- three levels were analyzed for each parameter, except for a tool plunge …

An Evolutionary Approach Based On Viral Replication For Solving Combinatorial Optimization Problems, Claudia Evangelina Valles Sosa

Open Access Theses & Dissertations

A new multi-objective evolutionary algorithm that mimics the way viruses replicate is presented. The purpose of viral replication is to allow the reproduction and survival of its kind. The algorithm is able to produce a large number of solutions to be evaluated by imitating the way viral replication and the infection process work. The well-known multi-objective redundancy allocation problem is used to show the performance of this new viral-based evolutionary approach. The algorithm considers the maximization of system reliability, the minimization of system cost, and the minimization of system weight to be optimized simultaneously. The solution to the multi-objective optimization …

Development Of Load Balancing Algorithm Based On Analysis Of Multi-Core Architecture On Beowulf Cluster, Damian Valles

Open Access Theses & Dissertations

In this work, analysis, and modeling were employed to improve the Linux Scheduler for HPC use. The performance throughput of a single compute-node of the 23 node Beowulf cluster, Virgo 2.0, was analyzed to find bottlenecks and limitations that affected performance in the processing hardware where each compute-node consisted of two quad-core processors with eight gigabytes of memory. The analysis was performed using the High Performance Linpack (HPL) benchmark.

In addition, the processing hardware of the compute-node was modeled using an Instruction per Cycle (IPC) metric that was estimated using linear regression. Modeling data was obtained by using the Tuning …

Effects Of The Usage Of Parallel Hardware Architectures In The Simulation Of Artificial Neural Networks Training Process, Carlos Beas

Open Access Theses & Dissertations

Long training times and non-ideal performance have been a big impediment in further continuing the use of Artificial Neural Networks for real world applications. Current research is currently focused on two areas of study that aim to address this problem. The first approach seeks to overcome large training times by devising faster learning algorithms where a set of interconnection weights for which the network produces negligible error takes a less amount of computation to find [Sun98]. The second approach aims to address the impediment by implementing existing training algorithms but on parallel hardware architectures.

While both approaches provide promising advances …

Teachers Perspectives: An Understanding Of Adhd In A Predominantly Hispanic School District, Heriberto Jesus Oronoz

Open Access Theses & Dissertations

The current study examined problems that teachers encounter when trying to cope with Attention Deficit Hyperactivity Disorder (ADHD) in the classroom, teachers' perceptions and beliefs about ADHD, as well as their ideas for how to improve services to children with ADHD. To do so, ten in- depth interviews were conducted with teachers from the Canutillo Independent School District in El Paso, TX regarding these topics. Findings reveal that teachers encounter difficulties defining ADHD, dealing with ADHD in the classroom, establishing the proper chain of command for diagnosing children, and with inadequate parental involvement. Further, the study found variability in teachers' …

The Role Of Perceptual Processes In The Use Of And Willingness To Use Professional Health Care Services, Luis Omar Rivera

Open Access Theses & Dissertations

To better address ethnic health disparities, it is imperative that we understand the psychological processes that shape people's use of and willingness to use professional health care services. The current research proposes and tests a model in which people's attentional orientation toward context discourages them from seeking professional health care services because (a) attentional orientation toward context encourages people to attribute symptoms of illness to external/environmental factors and (b) attributing symptoms of illness to external/environmental factors is associated with less use of professional health care services. The results of two studies show mixed support for the proposed model. Consistent with …

Seismological Studies In South-Central Alaska And Northern Mexico, Oscar Mario Romero De La Cruz

Open Access Theses & Dissertations

The work in this study is focused on two different areas, south-central Alaska and northern Mexico. In the first study area, I calculated dynamic stress drops for moderate sized earthquakes and performed receiver function analyses. The goal of the stress drop studies was to determine if events occurring within the more strongly coupled portion of the subducting slab have higher stress drops. My results shows that higher stress drops correspond to the locked and strongly coupled region in Prince William Sound, and lower stress drops are associated with the Cook Inlet region, a zone of relaxation of the plate interface. …

The Relationship Between Divided Government And Real Per Capita Gross State Product, Adrian Christopher Villasenor

Open Access Theses & Dissertations

This paper analyzes the relationship between divided government and real per capita gross state product in U.S. states using a panel study of data from all of the contiguous U.S. states, except Nebraska, for the period of 1990 to 2007. Some literature can be found on the relationship between divided government and economic growth at the national level. There is a lack of study of this relationship at the state level. Real per capita gross state product is the dependent variable in this study. Divided government, partisan control of the governor's office, partisan control of the state legislature, combined federal …

Bab Edh-Dhra', Numeira, And The Biblical Patriarchs: A Chronological Study, Kris J. Udd

Dissertations

Problem. Bab edh-Dhra' and Numeira have been identified by archaeologists as possible candidates for two of the biblical cities of the plain, but their existence in the Early Bronze Age III is too early to match the biblical narrative (Gen 19) by many chronologies of ancient Canaan. This study sought to determine if there is sufficient flexibility in the archaeological and biblical chronologies to make the identification of Bab edh-Dhra' and Numeira with the cities of the plain a viable interpretation.

Method. The range of dates possible for both the archaeological data and the biblical narratives was analyzed. …

A Novel Countermeasure Against The Reaction Time Index Of Countermeasure Use In The P300-Based Complex Trial Protocol For Detection Of Concealed Information, Alexander Sokolovsky, Jessica Rothenberg, Elena Labkovsky, John B. Meixner Jr., J. Peter Rosenfeld

Scholarly Works

A P300 deception detection protocol was tested using simultaneous versus serial countermeasures and stimulus acknowledgment responses. Previously, P300 showed recognition and elevated reaction time identified countermeasure use. Probe-irrelevant P300 differences were significant in both countermeasure groups and control group. Detection rates were 11/12 for controls, 10/12 for serial countermeasure users, and 11/13 for simultaneous countermeasure users. Reaction time detected countermeasure use in serial responders, but not simultaneous responders. The simultaneous response reaction times were indistinguishable from controls.

Prosecutorial Discretion And The Neglect Of Juvenile Shielding Statutes, Andrea L. Dennis

Scholarly Works

When legislatures enact statutes, furtherance of legislative intent depends on the behavior of actors in the executive and judicial branches of government. In the criminal justice system, prosecutors may frustrate legislative intent when they exercise prosecutorial discretion. This Article examines an instance in which prosecutors’ choices work to the detriment of children.

This Article reviews the failure of juvenile shielding statutes to take hold in the prosecution of cases involving child witnesses because of prosecutors’ discretionary decisions not to use these statutes. The Article investigates prosecutors’ pragmatic and doctrinal justifications for not utilizing juvenile shielding statutes and concludes that the …

Big 4 Auditor Affiliation And Accruals Quality In Bangladesh, M. Humayun Kabir, Divesh Sharma, Md Ainul Islam, Amiros Salat

Faculty Articles

Purpose – Bangladesh is an emerging economy and international audit firms operate there through affiliated local audit firms. The Bangladesh audit market can be characterized as an intensely competitive small audit market with relatively poor demand for high-audit quality. In addition, Bangladesh has a relatively small and under developed but growing capital market that is characterized by poor corporate regulation and weak investor protection. The purpose of this paper is to examine the association between Big 4 affiliated auditors and accruals quality in Bangladesh.

Design/methodology/approach – Following prior literature, this paper uses both absolute discretionary accruals and signed discretionary accruals …

Environmental Law, Eleventh Circuit Review, Travis M. Trimble

Scholarly Works

Relatively few environmental cases were decided in the United States Court of Appeals for the Eleventh Circuit in 2010. The court decided a case holding that the portion of the Omnibus Appropriations Act of 2009, which funded a mile-long bridge in the Everglades, repealed the National Environmental Policy Act of 1969, Endangered Species Act, and other environmental laws to the extent they applied to the construction project. Additionally, the court decided that the leadbased paint hazard warning required to be included in residential leases pursuant to the Residential Lead-Based Paint Hazard Reduction Act had to be reproduced in such leases …

Substance, Procedure, And The Divided Patent Power, Joseph S. Miller

Scholarly Works

The Patent Office has the power to issue rules that “shall govern the conduct of proceedings in the Office,” 35 U.S.C. § 2(b)(2), but not the power to issue substantive rules. It has been this way since 1870, when Congress first granted the Office this regulatory power, in nearly these same words. Just how broad is this grant? How should a reviewing court determine whether a challenged Patent Office rule is procedural (and thus valid) or substantive (and thus invalid)? It is remarkable that in 2010, 140 years after Congress gave the Patent Office this power, the proper sorting standard …

Law Asks For Trust, Nathan Chapman

Scholarly Works

This Article offers a reading of chapters 1 and 2 of the book of Genesis, informed by concerns for the social effects of law. Part I considers the implications of God's method of creating the world by speech in the first chapter of Genesis. Part II turns to God's prohibition against eating the fruit of the tree of the knowledge of good and evil. The content of the prohibition and the nature of the threatened penalty suggest that the prohibition is a rule against disobedience generally, paradigmatic of a general claim by God to be the ruler. With the creation …

Class Matters, Erica J. Hashimoto

Scholarly Works

Poor people constitute one of the most overrepresented categories of people in the criminal justice system. Why is that so? Unfortunately, we simply do not know, in large part because we have virtually no information that could provide an answer. As a result of that informational vacuum, policymakers either have ignored issues related to socioeconomic class, instead focusing on issues like drug addiction and mental illness as to which there are more data, or have developed fragmented policy that touches on socioeconomic class issues only tangentially. The bottom line is that without better data on the profile of poor defendants, …

Corporate Governance In An Age Of Separation Of Ownership From Ownership, Usha Rodrigues

Scholarly Works

The shareholder empowerment provisions enacted as part of the recent bailout legislation are internally incoherent because they fail to address the short-termist realities of shareholder ownership today. Ownership has separated from ownership in modern corporate America: individual investors now largely hold stock through mutual funds, pension funds, and hedge funds. The incentives of these short-term financial intermediaries only imperfectly reflect the interests of their long-term holders - an imbalance only exacerbated by the bailout’s corporate governance legislation. The bailout’s focus on shareholder empowerment tactics - such as proxy access, say-on-pay, and increased disclosure - makes little sense if shareholders are …

Resolving Interstate Conflicts Over Same-Sex Non-Marriage, Hillel Y. Levin

Scholarly Works

States have adopted several different regimes of recognition for same-sex couples. A few states allow same-sex couples to marry; several others offer marriage-like partnerships (usually called civil unions), which provide all or nearly all of the substantive rights and responsibilities associated with marriage; still others offer marriage-lite partnerships (sometimes called reciprocal benefits arrangements), which provide a small subset of the rights and responsibilities associated with marriage; and, of course, others offer no recognition at all.

What happens when these regimes of recognition collide? For example, what happens when a couple marries in Massachusetts and then moves to a marriage-like state, …

Time And Change In Judge-Made Law: Convergence, Divisions Of Authority, And The Restatement, Michael Wells

Scholarly Works

In his contribution to Wake Forest Law School’s 2009 Symposium on the Restatement (Third) of Torts, Professor Kenneth Abraham starts with two propositions, one descriptive, the other normative. The descriptive claim is that “tort law . . . is mature and largely stable,” and that “[o]ver time, the law of different states will converge.” As he points out, “The formation of the American Law Institute (“ALI”) itself, and the project of restating the law that the ALI . . . undertook” depends on these premises.

The project of restating the law also depends on a normative premise, namely that …

Congenital Cardiac Defect In A Pygmy Goat (Capra Hircus), Fulvio Laus, Ilenia Copponi, Matteo Cerquetella, Alessandro Fruganti

Turkish Journal of Veterinary & Animal Sciences

Congenital cardiac defects are anatomic conditions present at birth. Few references to such conditions in goats are available in the current scientific literature. This report describes, for the first time, a congenital cardiac disease clinically characterized by polypnea from birth and exercise intolerance in a 2-month-old pygmy goat. An atrioventricular dysplasia known as Ebstein's anomaly, an atrial septal defect, and a mild subaortic stenosis were ultrasonographically diagnosed.

De Novo Characterization Of The Gametophyte Transcriptome In Bracken Fern, Pteridium Aquilinum, J. P. Der, M. S. Barker, N. J. Wickett, C. W. Depamphilis, Paul G. Wolf

Biology Faculty Publications

Because of their phylogenetic position and unique characteristics of their biology and life cycle, ferns represent an important lineage for studying the evolution of land plants. Large and complex genomes in ferns combined with the absence of economically important species have been a barrier to the development of genomic resources. However, high throughput sequencing technologies are now being widely applied to non-model species. We leveraged the Roche 454 GS-FLX Titanium pyrosequencing platform in sequencing the gametophyte transcriptome of bracken fern (Pteridium aquilinum) to develop genomic resources for evolutionary studies.

The Evolution Of Chloroplast Genes And Genomes In Ferns, Paul G. Wolf, J. P. Der, A. M. Duffy, J. B. Davidson, A. L. Grusz, K. M. Pryer

Biology Faculty Publications

Most of the publicly available data on chloroplast (plastid) genes and genomes come from seed plants, with relatively little information from their sister group, the ferns. Here we describe several broad evolutionary patterns and processes in fern plastid genomes (plastomes), and we include some new plastome sequence data. We review what we know about the evolutionary history of plastome structure across the fern phylogeny and we compare plastome organization and patterns of evolution in ferns to those in seed plants. A large clade of ferns is characterized by a plastome that has been reorganized with respect to the ancestral gene …

Aggregate Litigation: Critical Perspectives, Roger H. Trangsrud

GW Law Faculty Publications & Other Works

While aggregate litigation has become an integral part of the U.S. civil justice system, it is often the cause of intense controversy among the private bar, the bench, and the academy. In 2009, the American Law Institute completed a project on the Principles of the Law of Aggregate Litigation, whose goal was to identify good procedures for handling aggregate lawsuits. The completion of these Principles spurred a host of reactions from attorneys, judges, and scholars. At a symposium hosted by The George Washington University Law School, the questions that were posed included: What is the optimal level of aggregation? When …
