Decomposition Patterns And Nitrogen Dynamics Of Black Mangrove (Avicennia Germinans)Leaf Litter In Disturbed Estuaries Linked To The Lower Laguna Madre, Texas, Mario Alberto Marquez

Theses and Dissertations - UTB/UTPA

Estuaries are among the most productive aquatic systems in the world but are subject to both anthropogenic and natural disturbances. With increasing environmental concerns, efforts have become commonplace in assessing the status and trends of environmental conditions. In this study, an assessment of ecosystem status of various estuaries affected by different disturbances, was attempted through the examination of key functional processes such as leaf litter decomposition and nutrient dynamics during decay. Three estuaries located along the Brownsville Ship Channel near the southern terminus of the Lower Laguna Madre in Texas were studied. The overlying goal of this study was to …

Design And Configuration Of Laser Tweezers Microscopy For Force Measurements On Single Dna Molecules, Carlos Jeziel Gonzalez Banuelos

Theses and Dissertations - UTB/UTPA

In this study, a detailed description of the optical tweezers microscopy technique is presented, as well as the methodologies used to prepare the DNA molecule for mechanical measurements at the nanoscale. The main objective is to initiate and extend the experimental biophysical studies on the DNA-proteins interactions at the University of Texas at Brownsville (UTB). DNA-binding proteins control almost all aspects of cellular function, such as transcription; chromosome maintenance, replication and DNA repair depend on the interaction of proteins with DNA. In view of such an important role played by DNA–protein interactions, various techniques have evolved over the years to …

Awareness And Usage Of Collaboration And Communication Technologies In Student Teamwork , Manouchehr Tabatabaei, Marco Lam

Journal of International Technology and Information Management

In this study, we investigate students’ awareness and usage of collaboration and communication technologies (CCTs). Coordination and communication are two of the key processes for effective teamwork that have been identified in the literature. We find significant differences in awareness of CCTs between various student groups. However, when controlling for awareness, we find no difference in usage. While the proportion of students that are aware of various CCTs is high, the reported usage of CCTs is low. Because of the increased emphasis on teamwork, students need to be taught the technologies they need to use for collaboration and communication in …

WCBT Faculty Publications

This study examined the relationships between selling teams (STs) and customer satisfaction within the mission critical power design industry. The literature indicates that STs, which are considered a state of the art sales model, deserved further research. The SERVQUAL survey was used to measure customer satisfaction with EYP Mission Critical’s most strategic customers. The difference in customer satisfaction for customers serviced by STs and traditional sales personnel were compared. The investigation found support indicating that a ST approach had a positive relationship to increased customer satisfaction levels. Based on the results of the study, it is recommended that sales leaders …

Sources Of Nutrient And Fecal Microbe Pollution In Otter Creek, Madison County, Kentucky, Kandice L. Smith, Walter S. Borowski

EKU Faculty and Staff Scholarship

We measured nutrient (nitrate, ammonium, phosphate) and fecal microbe concentrations in surface waters of the Otter Creek watershed, Madison County, Kentucky to access sources of these contaminants. The watershed is approximately 12.5 miles long covering ~169 km² (41,832 acres). The watershed includes East Fork, West Fork, and Dreaming Creek, all tributaries to the main trunk of Otter Creek. The upper portion of the main trunk and Dreaming Creek drain urban areas of Richmond, but 85% of total watershed area is agricultural land, used mainly for grazing cattle. Rural residential areas and woodlands also occur.

The principle contaminants are nutrients …

Modeling Acute Respiratory Illness During The 2007 San Diego Wildland Fires Using A Coupled Emissions-Transport System And General Additive Modeling, Brian Thelen, Nancy H. F. French, Benjamin W. Koziol, Michael Billmire, Robert Chris Owen, Jeffrey Johnson, Michele Ginsberg, Tatiana Loboda, Shiliang Wu

Michigan Tech Research Institute Publications

Background

A study of the impacts on respiratory health of the 2007 wildland fires in and around San Diego County, California is presented. This study helps to address the impact of fire emissions on human health by modeling the exposure potential of proximate populations to atmospheric particulate matter (PM) from vegetation fires. Currently, there is no standard methodology to model and forecast the potential respiratory health effects of PM plumes from wildland fires, and in part this is due to a lack of methodology for rigorously relating the two. The contribution in this research specifically targets that absence by modeling …

Detecting Stable Communities In Large Scale Networks, Sriram Srinivasan

Student Work

A network is said to exhibit community structure if the nodes of the network can be easily grouped into groups of nodes, such that each group is densely connected internally but sparsely connected with other groups. Most real world networks exhibit community structure.

A popular technique for detecting communities is based on computing the modularity of the network. Modularity reflects how well the vertices in a group are connected as opposed to being randomly connected. We propose a parallel algorithm for detecting modularity in large networks.

However, all modularity based algorithms for detecting community structure are affected by the order …

How Much Is That Lawsuit In The Window? Pricing Legal Claims, Maya Steinitz

Vanderbilt Law Review

Assessing the value of legal claims is the sixty-four thousand dollar question (no pun intended) of civil litigation. Clients, as every litigator knows, often come into their attorneys' offices with a belief that they know how much their claim is worth. The attorney is then asked to validate that number. Alternately, clients can come to their attorneys with a grievance-I have been injured, a counter-party breached its contract with me, I have been fired, our rainforest has been devastated by a mining company-and ask the attorney for an assessment of how much their grievance might be worth. Contingency lawyers, who …

Performance Analysis Of Non-Linear Adaptive Control Laws Using Hardware In The Loop Of An Unmanned Aerial System, Brendon Lyons

Doctoral Dissertations and Master's Theses

In practical applications, an Unmanned Aerial System's (UAS) baseline performance is dictated by how well it can follow a given trajectory with limited stress on the actuators. However, these can be insufficient performance metrics when the UAS is allowed to adapt to an unpredicted external influence such as turbulence or actuation failure, while maintaining a satisfactory baseline performance.

In this thesis, different control laws based on the formation flight geometry problem, nonlinear dynamic inversion and an artificial immune system adaptive mechanism , are implemented in hardware-in-the-loop as a precursor for in-flight testing. These controllers are compared based on three performance …

Early Career Change Among Millennial Us College Graduates, Gina Sian

College of Liberal Arts & Social Sciences Theses and Dissertations

With employers reporting high turnover among millennial employees, there is a need for better understanding of employment characteristics of this generation of workers. By analyzing the job history of 1,000 American millennials who participated in the National Longitudinal Survey of the Youth, this study found that 26% of millennial US college graduates changed careers within the first five years after obtaining their degree, but no more than past generations when they were young. Analysis also found that flexibility and optimism are not significant predictors of early career change but openness to risk has a strong positive association with early career …

Towards Automated Network Configuration Management, Khalid Elmansor

College of Computing and Digital Media Dissertations

Modern networks are designed to satisfy a wide variety of competing goals related to network operation requirements such as reachability, security, performance, reliability and availability. These high level goals are realized through a complex chain of low level configuration commands performed on network devices.

As networks become larger, more complex and more heterogeneous, human errors become the most significant threat to network operation and the main cause of network outage. In addition, the gap between high-level requirements and low-level configuration data is continuously increasing and difficult to close. Although many solutions have been introduced to reduce the complexity of configuration …

A Subelliptic Analogue Of Aronson-Serrin's Harnack Inequality, Luca Capogna, Giovanna Citti, Garrett Rea

Mathematics Sciences: Faculty Publications

We study the Harnack inequality for weak solutions of a class of degenerate parabolic quasilinear PDE,(Formula presented.) in cylinders Ω × (0,T) where Ω ⊂ M is an open subset of a manifold M endowed with control metric d corresponding to a system of Lipschitz continuous vector fields X=(X_1,..., X_m) and a measure dσ. We show that the Harnack inequality follows from the basic hypothesis of doubling condition and a weak Poincaré inequality in the metric measure space (M,d,dσ). We also show that such hypothesis hold for a class of Riemannian metrics gε collapsing to a sub-Riemannian metric limε → …

Relationships Between Body Roundness With Body Fat And Visceral Adipose Tissue Emerging From A New Geometrical Model, Diana M. Thomas, Carl Bredlau, Anja Bosy-Westphal, Manfred Mueller, Wei Shen, Dympna Gallagher, Yuna Maeda, Andrew Mcdougall, Courtney M. Peterson, Eric Ravussin, Steven B. Heymsfield

Department of Mathematics Faculty Scholarship and Creative Works

Objective To develop a new geometrical index that combines height, waist circumference (WC), and hip circumference (HC) and relate this index to total and visceral body fat. Design and Methods Subject data were pooled from three databases that contained demographic, anthropometric, dual energy X-ray absorptiometry (DXA) measured fat mass, and magnetic resonance imaging measured visceral adipose tissue (VAT) volume. Two elliptical models of the human body were developed. Body roundness was calculated from the model using a well-established constant arising from the theory. Regression models based on eccentricity and other variables were used to predict %body fat and %VAT. Results …

Computer Science: Faculty Publications and Other Works

How can we rethink the definition of algorithm, and through that, produce another age of enlightenment in modern scientific programming and software development in general? Removing these limitations in our own thoughts is the key for expanding the possibilities in alternative paradigms and exploiting parallel and next-generation hardware.

Citizenship Education In The Social Science Subjects: An Analysis Of The Teacher Education Curriculum For Secondary Schools, Aaron T. Sigauke

Australian Journal of Teacher Education

Citizenship education is widely acknowledged as a necessary part of the school curriculum for various reasons. For young people, it is assumed that citizenship can best be learnt through the school curriculum. This means that teachers need to thoroughly understand what citizenship means and how to pass this knowledge on to students.

This paper examines the nature of civics and citizenship education offered in the social sciences teacher education program at a teacher education institution in Australia. It analyses ten social science subject syllabuses to find out how pre-service teachers are trained about teaching citizenship education in schools when they …

Teaching Behaviour And Well-Being In Students : Development And Concurrent Validity Of An Instrument To Measure Student-Reported Teaching Behaviour., Patrick Possel, Kathleen Moritz Rudasill, Jill L. Adelson, Annie C. Bjerg, Don T. Wooldridge, Stephanie Winkeljohn Black

Faculty and Staff Scholarship

Teaching behavior has important implications for students’ emotional well-being. Multiple models suggest students’ perceptions of teaching behaviors are more critical than other measures for predicting well-being, yet student-report instruments that measure concrete and specific teaching behavior are limited. The purpose of the present studies is to develop an instrument to assess students’ perceptions of concrete and specific teaching behavior and to test which teaching behavior is associated students’ well-being. Construct validity and internal consistency for the 37-item Teaching Behavior Questionnaire (TBQ-S), composed of instructional, negative teaching, socioemotional, and organizational behavior were examined using data from two independent samples (Study 1: …

What You Want Is Not What You Get: Predicting Sharing Policies For Text-Based Content On Facebook, Arunesh Sinha, Li Yan, Lujo Bauer

Research Collection Lee Kong Chian School Of Business

As the amount of content users publish on social networking sites rises, so do the danger and costs of inadvertently sharing content with an unintended audience. Studies repeatedly show that users frequently misconfigure their policies or misunderstand the privacy features offered by social networks. A way to mitigate these problems is to develop automated tools to assist users in correctly setting their policy. This paper explores the viability of one such approach: we examine the extent to which machine learning can be used to deduce users' sharing preferences for content posted on Facebook. To generate data on which to evaluate …

Top Quark Production, Nikolaos Kidonakis

Faculty Articles

I discuss top quark production in hadronic collisions. I present the soft-gluon resummation formalism and its derivation from factorization and renormalization-group evolution, and two-loop calculations of soft anomalous dimensions in the eikonal approximation. I discuss the contributions of next-to-next-to-leading order (NNLO) soft-gluon corrections to the total cross sections and top-quark transverse momentum and rapidity distributions for top-antitop pair production, and for single-top production in the t and s channels and in association with a W boson or a charged Higgs boson.

Gathering “Wild” Food In The City: Rethinking The Role Of Foraging In Urban Ecosystem Planning And Management, Rebecca J. Mclain, Patrick T. Hurley, Marla R. Emery, Melissa R. Poe

Institute for Sustainable Solutions Publications and Presentations

Recent “green” planning initiatives envision food production, including urban agriculture and livestock production, as desirable elements of sustainable cities. We use an integrated urban political ecology and human–plant geographies framework to explore how foraging for “wild” foods in cities, a subversive practice that challenges prevailing views about the roles of humans in urban green spaces, has potential to also support sustainability goals. Drawing on research from Baltimore, New York City, Philadelphia, and Seattle, we show that foraging is a vibrant and ongoing practice among diverse urban residents in the USA. At the same time, as reflected in regulations, planning practices, …

The Effects Of A Red Tide, Karenia Brevis Episode On The Benthic Macroinvertebrate Communities Of South Padre Island, Texas, Liana Lerma

Theses and Dissertations - UTB/UTPA

South Padre Island, Texas has experienced increasing frequency of harmful algal blooms (Karenia brevis) since the 1900’s, many of which resulted in massive fishes kills. In addition, shorebirds and other terrestrial wildlife deaths have been linked to K. brevis blooms prompting investigations of potential pathways by which brevetoxins may be transmitted to higher trophic levels. The benthic macrofanual community inhabiting the swash zone of sandy beaches consists primarily of filter feeding invertebrates which may serve as toxin bioaccumulators to secondary consumers of both marine and terrestrial food webs. The first reported mass mortality of swash zone benthic macrofauna on the …
