Detecting Radiation Reaction At Moderate Laser Intensities., Thomas Heinzl, Chris Harvey, Anton Ilderton, Mattias Marklund, Stepan S. Bulanov, Sergey Rykovanov, Carl B. Schroeder, Eric Esarey, Wim P. Leemans

School of Engineering, Computing and Mathematics

We propose a new method of detecting radiation reaction effects in the motion of particles subjected to laser pulses of moderate intensity and long duration. The effect becomes sizable for particles that gain almost no energy through the interaction with the laser pulse. Hence, there are regions of parameter space in which radiation reaction is actually the dominant influence on charged particle motion.

Adverse Childhood Experience And Asthma Onset: A Systematic Review, Daniel Exley, Alyson Norman, Michael Hyland

School of Psychology

Adverse childhood experiences such as abuse and neglect are associated with subsequent immune dysregulation. Some studies show an association between adverse childhood experiences and asthma onset, although significant disparity in results exists in the published literature.We aimed to review available studies employing a prospective design that investigates associations between adverse childhood experience and asthma. A search protocol was developed and studies were drawn from four electronic journal databases. Studies were selected in accordance with pre-set inclusion criteria and relevant data were extracted.12 studies, assessing data from a total of 31 524 individuals, were identified that investigate the impact of a …

3d Fea Modelling Of Laminated Composites In Bending And Their Failure Mechanisms, M. Meng, H. R. Le, M. J. Rizvi, S. M. Grove

School of Engineering, Computing and Mathematics

Abstract This paper developed three-dimensional (3D) Finite Element Analysis (FEA) to investigate the effect of fibre lay-up on the initiation of failure of laminated composites in bending. Tsai-Hill failure criterion was applied to identify the critical areas of failure in composite laminates. In accordance with the 3D FEA, unidirectional ([0]16), cross-ply ([0/90]4s) and angle-ply ([±45]4s) laminates made up of pre-preg Carbon Fibre Reinforced Plastics (CFRP) composites were manufactured and tested under three-point bending. The basic principles of Classical Laminate Theory (CLT) were extended to three-dimension, and the analytical solution was critically compared with the FEA results. The 3D FEA results …

The Fake Bad Scale: Malingering Or Litigation Response Syndrome -- Which Is It?, David S. Nichols, Carlton S. Gass

Archives of Assessment Psychology

This report examines the similarity of items on the MMPI-2 and MMPI-2-RF versions of the Lees-Haley, et al. (1991) Symptom Validity (formerly Fake Bad) Scale (FBS; FBS-r) with emotional and somatic symptoms described in an earlier article by Lees-Haley as credible stress reactions to litigation involvement: the Litigation Response Syndrome (Lees-Haley, 1988). Substantial overlap was found between the FBS items and these earlier symptom descriptions, with a majority of the litigation-based stress items found on both the FBS and FBS-r. The probable impact of credible symptom reporting on FBS/FBS-r scores in personal injury litigation is discussed.

A New Characterization Of Fine Scale Diffusion On The Cell Membrane, Flor A. Espinoza, Stanly L. Steinberg

Faculty Articles

We use a large single particle tracking data set to analyze the short time and small spatial scale motion of quantum dots labeling proteins in cell membranes. Our analysis focuses on the jumps which are the changes in the position of the quantum dots between frames in a movie of their motion. Previously we have shown that the directions of the jumps are uniformly distributed and the jump lengths can be characterized by a double power law distribution. Here we show that the jumps over a small number of time steps can be described by scalings of a single double …

Millennial-Scale Variability In The Indian Monsoon And Links To Ocean Circulation, Kimberly Anne Delong

Master's Theses and Capstones

Millennial-scale variability in the Indian monsoon was temporally linked to changes in global ocean circulation during the last glacial period, as evidenced by planktic-benthic foraminiferal stable isotope and trace element results from an intermediate depth sediment core from the northwestern Bay of Bengal (Core NGHP-01-19B; 18°58'N, 85°39'E; 1,422 m). Paired planktic foraminiferal Mg/Ca and d18Oc of G. ruber constrain sea surface temperatures and isolate millennial-scale variations in the d18O of surface waters (d18Osw) which resulted from changes in river runoff in the northwestern Bay. Concurrently with low d18Osw events, benthic foraminiferal d13C of Cibicidoides spp. decreased, suggesting an increased influence …

Separations Of Wealth: Inequality And The Erosion Of Checks And Balances, Kate Andrias

Faculty Scholarship

American government is dysfunctional: Gridlock, filibusters, and expanding presidential power, everyone seems to agree, threaten our basic system of constitutional governance. Who, or what, is to blame? In the standard account, the fault lies with the increasing polarization of our political parties. That standard story, however, ignores an important culprit: Concentrated wealth and its organization to achieve political ends. The only way to understand our current constitutional predicament – and to rectify it – is to pay more attention to the role that organized wealth plays in our system of checks and balances.

This Article shows that the increasing concentration …

Learning To Teach English Learners: Instructional Coaching And Developing Novice High School Teacher Capacity, Felice Atesoglu Russell

Faculty Articles

The number of English learners (ELs) in our schools continues to increase, and at the same time, the academic achievement of ELs consistently lags behind the achievement of native-English-speaking peers (Goldenberg & Coleman, 2010). These second language learners bring with them a set of special needs for teaching and learning, especially for mainstream content area teachers, who often have little or no specialized training for meeting these needs (Bunch, 2010). Although there is not yet extensive empirical work focused on how mainstream content teachers at the secondary level typically teach ELs or how they learn to more effectively teach these …

Predictors Of Enrolling In Online Courses: An Exploratory Study Of Students In Undergraduate Marketing Courses, Renee J. Fontenot, Richard E. Mathisen, Susan S. Carley, Randy S. Stuart

Faculty Articles

An exploratory study of undergraduate students enrolled in marketing courses at a Southeastern regional university was conducted to determine the motivations and characteristics of marketing students who plan to be online learners and examined for differences between those who have taken and those who have not taken online classes. An online survey of Likert scales, openended questions and demographic questions was sent via class learning management websites. A total of 165 students of the 438 invited to participate completed the survey. A structural model was developed using SMART-PLS to estimate the relationships of constructs that predict taking online courses. Results …

Secured Credit In Religious Institutions' Reorganizations, Pamela Foohey

Scholarly Works

Scholars increasingly assume that most businesses enter Chapter 11 with a high percentage of secured debt, which leads to a high percentage of cases ending in the sale of the debtor’s assets under section 363 of the Bankruptcy Code rather than with confirmation of a reorganization plan. However, evidence and discussions about “the end of bankruptcy” center on secured creditors’ role in the reorganizations of very large corporations. The few analyses of cross-sections of Chapter 11 proceedings suggest that secured creditor control is not nearly as omnipresent as asserted and that 363 sales are not as dominant as assumed.

Design Optimization And Optical Characterization Of A High Temperature Solar Receiver, Samia Afrin

Open Access Theses & Dissertations

Concentrated solar power (CSP) is a fast forwarding technology in power generation sector because of its' competitive price, abundance in nature and the most important fact is its' energy storage capability. Among the four types of available CSP technology, central receiver has more potential concerning with high temperature, power block efficiency and levelized cost of energy (LCOE). Other than conventional type of receiver design, the concept of this work is very particular in a sense of its design novelty.

National Renewable Energy Laboratory (NREL) come up with a new concept of high temperature solar receiver called near black body (NBB) …

A Comparative Assessment Of Electrophysiological And Behavioral Performance In Individuals With Aphasia Responding To Spoken And Written Sentence Length Commands, Sha-Renae Alexander

Open Access Theses & Dissertations

The aim of this study is to investigate whether deficits in processing affect auditory and reading comprehension in the same manner. This study compared the behavioral and electrophysiologic performance of four individuals with aphasia and four participants with no brain damage responding to spoken and written sentence length commands using a modified version of the Revised Token Test (McNeil & Prescott, 1978). Electrophysiological responses were recorded from the scalp using event related potentials (ERP). The latency and amplitude of the N400 ERP component were measured and analyzed. Behavioral reaction times and correct responses were collected and examined. Performance differences between …

Dynamic Triggering In The Coso Geothermal Field, 2004-2013, Richard A. Alfaro-Diaz

Open Access Theses & Dissertations

We take advantage of EarthScope’s USArray Transportable Array (TA), regional seismic networks to investigate 154 M ≥ 7 earthquakes over a ten-year period (2004- 2013), in search of remotely triggered seismicity within the continental United States. We conduct an automated search to detect high frequency signals (which may indicate triggering of small local earthquakes) using a time window of 5 hours before and after each mainshock. The automated detection applies a short-term average (STA) to long-term-average (LTA) algorithms, to create a catalogue of detections. Using the catalog we search for an increase in detection rates after each main-shock. Sharp increases …

Acculturation, Psychological Distress, And Smoking In Latinos Living With Hiv/Aids, Jessica Armendariz

Open Access Theses & Dissertations

In the United States smoking cigarettes is the leading cause of preventable death, and smoking is of particular health concern among people living with HIV. Depression has been consistently linked to smoking in the literature, and data indicate that acculturation to the U.S. is associated with increased depression among Latinos.

This study examined if acculturation moderates the impact of depression on smoking behavior among Latinos living with HIV through the mediating effect of social support. The results may extend to the sociopsychological construct of culture. We studied 300 Latinos who live with HIV on the U.S./Mexico border.

Results demonstrated there …

Restraint Stress Alters Pro-Inflammatory Cytokine Expression And Increases Superoxide Dismutase In The Rat Hypothalamus And Hippocampus, Kristina Isabel Barron

Open Access Theses & Dissertations

The impact of restraint stress on changes in cytokine expression and oxidative stress markers in hippocampal (Hipp) and hypothalamic (Hyp) regions of the brain, were assessed in a rat model. In addition, immune and inflammatory variables were assessed in peripheral blood. Male Wistar rats were acutely (30 min) or repeatedly (30 min/d for 14 consecutive days) exposed to a restraint stress, or maintained as non-stressed controls. At the time of sacrifice, whole blood and brain tissues enriched in Hyp or Hipp regions were collected; blood was collected with EDTA as an anticoagulant and centrifuged to yield plasma. All tissue samples …

Challenges In Assessing College Students' Conception Of Duality: The Case Of Infinity, Grace Olutayo Babarinsa-Ochiedike

Open Access Theses & Dissertations

Interpreting students' views of infinity posits a challenge for researchers due to the dynamic nature of the conception. There is diversity and variation among students' process-object perceptions. The fluctuations between studentsâ?? views however reveal an undeveloped duality conception. This study examined college students' conception of duality in understanding and representing infinity with the intent to design strategies that could guide researchers in categorizing students' views of infinity into different levels.

Data for the study were collected from N=238 college students enrolled in Calculus sequence courses (Pre-Calculus, Calculus I through Calculus III) at one of the southwestern universities in the U.S. …

Three Essays On Global Ict Phenomenon: Productivity Paradox, Organizational Ict Use, And Privacy In Social Networks, Faruk Arslan

Open Access Theses & Dissertations

This Dissertation aims to investigate the global diversity in information systems by studying three distinctive phenomena. The first essay investigates the existence of "IT Productivity Paradox" within firms operating in developing countries using an empirical approach. IT Productivity Paradox has been a widely investigated topic within the context of developed countries and primarily studied within the context of developing countries using a single country. Our research addresses a gap in the literature, which is the study of IT Productivity Paradox across several developing countries with diverse characteristics. The second essay studies the contextual factors (firm characteristics and perception of external …

Salt And Mineral Recovery From High Salinity Waters, Osvaldo Alejandro Broesicke

Open Access Theses & Dissertations

Natural salt springs in the Salt Fork Basin in Crosby County, Texas, result in the natural salt pollution of the Brazos River, rendering it unusable for most potable purposes. Previous research indicates that by intercepting the source of the pollution, water quality of the Brazos River can be greatly improved. This paper investigates and assesses two strategies for salt and mineral recovery using natural brine collected from the Salt Fork Basin, the first of which is presented in a separate work.

The research described in this paper evaluates the potential of a desulfation, soda-caustic softening, acidification/decarbonation, and evaporation process to …

Evaluating Methods Of Field-Based 3d Visualization And Their Application To Mapping Metamorphic Terranes: An Example From The Panamint Mountains, California, Jade Ashley Brush

Open Access Theses & Dissertations

Field geology has traditionally relied on 2D, paper-based workflows, but digital mapping techniques are rapidly replacing these outdated methods because they allow for more efficient and accurate mapping. This research applies digital mapping techniques and two terrestrially-based 3D visualization technologies, photogrammetry and Light Detection and Ranging (LiDAR), to the study of metamorphic terranes in the Panamint Mountains, California. This study reports on the spatial accuracy of TINs (triangulated irregular networks) generated from both photogrammetry and ground-based LiDAR using a terrestrial laser scanner (TLS) and discusses how spatial accuracy can be increased. Two levels of comparison were used to test spatial …

Evaluation Of Point Of Use Drinking Water Treatment Systems For Colonias In The Southwest United States, Isaac Campos Flores

Open Access Theses & Dissertations

Clean drinking water is often taken for granted in first world countries, such as the United States. However, thousands of colonias residents (settlements in the Southwest US that lack access to basic infrastructure) still lack access to clean drinking water. Such is the case in the Paso Del Norte Region. In Doña Ana County, NM, and El Paso County, TX, colonia residents typically rely on shallow domestic wells and hauled water, respectively. However, both water sources can pose health concerns from elevated total dissolved solids and microbiological contamination. With connection to centralized water treatment and distribution still years away, colonias …

Reinterpretation Of The Mesozoic Thrust Complex Of The Southern Spring Mountains, Nevada, Warren Harding Allen

Open Access Theses & Dissertations

The east verging Keystone thrust fault in the southern Spring Mountains west of Goodsprings, Nevada, is mapped with a sharp bend in its trace near Keystone Wash. This bend was previously explained in the context of out-of-sequence thrusting and a salient-recess relationship along the thrust system; a simple redirection of the Keystone thrust to a north verging thrust. Recent geochronological studies indicate that the east verging Keystone thrust to the north of Keystone Wash formed between 83-103Ma. Approximately 5 kilometers to the east a north verging branch of the fault system overlies rocks as young as 99Ma. At the location …

Health And Stress Symptoms In University Professors And Their Relationship With The Process Of Obtaining A Permanent Position, Irene Concepcion Carrillo-Saucedo

Open Access Theses & Dissertations

This research study used a quantitative, correlational method to examine health and stress symptoms in university professors and their relationship with the process of obtaining a permanent position and participation in a merit pay program. The Stress Profile Inventory (PEN) was used to measure professors’ health habits, social support network, Type A behavior, cognitive hardiness, coping styles and psychological well-being. An original measure with a Likert-type scale was used to measure health status. The questionnaires were distributed to 104 professors from the Universidad Autónoma de Ciudad Juárez (UACJ) who provided voluntary participation. Based on the results of the study, certain …
