Digital Behavior Intervention Plans: Effects On General Education Teacher Fidelity Of Implementation, Christopher G. Holcomb

UNLV Theses, Dissertations, Professional Papers, and Capstones

Students with disabilities often have behavior that interferes with classroom learning. Serious problem behaviors are identified as the most significant factor interfering with learning in the classroom. Unfortunately, chronic behaviors often lead to a student dropping out of school. Current research typically focuses on areas of intervention for these students with little attention towards teacher fidelity of implementation of these interventions. Because of this, student's behavior intervention plans may not show effectiveness (e.g., progress monitoring, data driven decisions). It is important that researchers begin to explore systematic improvements in fidelity of implementation of behavior intervention plan components for general education …

Spectral Decomposition Of The Scattered Light Due To Deposits On The Solar Panel Surface, And Cross Correlated To Power Loss, Suzanna Ho

UNLV Theses, Dissertations, Professional Papers, and Capstones

The electric energy generated by solar panels declines due to dust particulates, bird deposits, water spots, and other contaminants that inhibit sunlight absorption and promote light scattering. As part of our research, we use cameras to capture images of solar panels, and analyze the images to detect the amount of scattered light. The more scattered light there is, the less light there is to penetrate the solar panel glass and reach the part of the panel that converts incident light to electric energy; therefore, less energy is generated. In this paper, we discuss the classification algorithm we developed to classify …

Postural Sway And Brain Hemispheric Power Spectral Density Under Different Attentional Focus Conditions, Sharon Jalene

UNLV Theses, Dissertations, Professional Papers, and Capstones

The purpose of this study was to determine the differences, if any, in the root mean square error (RMSE) of postural sway and hemispheric power spectral density (PSD) in the alpha and beta bands (8-12Hz and 12-25Hz) during different conditions of attentional focus (i.e., internal focus (IF), and external focus (EF) and a control condition (C)). Previous studies have shown that the adoption of IF and EF significantly alter motor performance and that EF promotes automaticity (Wulf, 2013). Sports performance and balance studies utilizing EEG spectral analyses report increased alpha oscillations during expert performance and stable balance and increased beta …

Maritime Piracy And Armed Robbery Confrontations Across The Globe: Can Crew Action Shape The Outcomes?, Justin Stewart Lewis

UNLV Theses, Dissertations, Professional Papers, and Capstones

Abstract

The recent tightening of military budget constraints has called into question the feasibility of costly multilateral naval intervention used to combat maritime piracy off the eastern coast of Africa. Though past studies agree that the transformation of the Somali economy and government is crucial for a long-term solution to piracy in this part of the world, short to medium-run solutions are needed to bridge the gap. Such solutions should be fiscally sensible and serve as effective deterrents, as well as be applicable in addressing the problem of piracy and maritime armed robbery in other parts of the globe.

UNLV Theses, Dissertations, Professional Papers, and Capstones

In order to assess the impact of salt structures on paleotemperatures in adjacent sedimentary rocks, a field based study which quantified thermally driven diagenetic products as a function of distance from salt was undertaken. Several salt diapirs are now exposed at the surface of the Earth within the Lusitanian Basin and offered a unique opportunity to document paleothermal anomalies by studying thermally controlled diagenesis in adjacent, exposed Upper Jurassic rocks. Four transects were chosen within Upper Jurassic rocks that contained both sandstones and mudstones. Quartz cementation and albitization of feldspars, both of which are thermally driven processes, were quantified in …

An Examination Of Implicit Values In Cornerstone Student Affairs Textbooks, Nathan Slife

UNLV Theses, Dissertations, Professional Papers, and Capstones

The field of student affairs is properly cautious about indoctrination. Indoctrination, after all, clearly contradicts the field's ethical statements and standards. These cautions have led student affairs researchers to investigate explicit values in the field to prevent explicit forms of indoctrination. However, recent investigations of implicit values in the discipline of psychology have revealed a potential new source of indoctrination not currently studied in student affairs. Specifically, psychological researchers have identified a system of implicit values called liberal individualism that has been found to be pervasive throughout the psychological discipline. Given the widely acknowledged link between student affairs and psychology, …

Increasing Bridge Deck Service Life: Volume Ii—Economic Evaluation, Samuel Labi, Robert J. Frosch, Ashish Samdariya, Qing Ye

JTRP Technical Reports

Deterioration of bridge decks is a primary factor limiting the lifespan of bridges especially in cold climates where deicing salts are commonly used. While controlling deck cracking or decreasing the permeability and porosity of concrete can improve performance and service life, chloride and moisture ingress as well as cracking cannot be eliminated. Full-depth cracks which are caused by restrained shrinkage allow for corrosive conditions at early ages for both the top and bottom reinforcement mats. Therefore, the use of corrosion-resistant reinforcement is essential to mitigate deterioration of bridge decks. The objective of this research program to examine the efficacy of …

A Multivariate Stochastic Unit Root Model With An Application To Derivative Pricing, Offer Lieberman, Peter C.B. Phillips

Cowles Foundation Discussion Papers

This paper extends recent findings of Lieberman and Phillips (2014) on stochastic unit root (SUR) models to a multivariate case including a comprehensive asymptotic theory for estimation of the model’s parameters. The extensions are useful because they lead to a generalization of the Black-Scholes formula for derivative pricing. In place of the standard assumption that the price process follows a geometric Brownian motion, we derive a new form of the Black-Scholes equation that allows for a multivariate time varying coefficient element in the price equation. The corresponding formula for the value of a European-type call option is obtained and shown …

Identifying Latent Structures In Panel Data, Liangjun Su, Zhentao Shi, Peter C.B. Phillips

Cowles Foundation Discussion Papers

This paper provides a novel mechanism for identifying and estimating latent group structures in panel data using penalized regression techniques. We focus on linear models where the slope parameters are heterogeneous across groups but homogenous within a group and the group membership is unknown. Two approaches are considered — penalized least squares (PLS) for models without endogenous regressors, and penalized GMM (PGMM) for models with endogeneity. In both cases we develop a new variant of Lasso called classifier-Lasso (C-Lasso) that serves to shrink individual coefficients to the unknown group-specific coefficients. C-Lasso achieves simultaneous classification and consistent estimation in a single …

A Secure Communication System For Early Childhood Collaboration System, Hao Kang

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

The Early Childhood collaboration System (ECCS) is a distributed health data system which provides coordinated, de-identified healthcare information to various types of data consumers. To satisfy this requirement, the ECCS needs a matcher that utilizes Personal Identifying Information (PII) to coordinate information from a wide range of data sources. Due to the sensitivity of PII, the ECCS also needs to guarantee that only matcher can access PII. This report describes a reusable subsystem, called Medical Records Secure Messaging (MRSecureMessaging), which utilizes a reliable cryptographic algorithm to encrypt PII and other confidential data so that matcher and data consumers cannot access …

Training Paraeducators To Use Behavior Management Strategies: Implementation And Evaluation Of A Brief Targeted Intervention, Aubrey Whiting

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Training paraprofessionals to be highly qualified providers of services to students with disabilities is a requirement of the Individuals with Disabilities Education Improvement Act (IDEIA), although many special education paraprofessionals still lack the skills and knowledge to work with students with special education needs – particularly those who engage in disruptive behaviors. This project evaluated the use of one module of a 10-week online paraeducator inservice training (Morgan et al., 2004) that focused on behavioral interventions. Five paraprofessionals who currently work at a public school for students with significant behavior problems in a rural school district in the Western United …

Synergistic Inhibition Of Cyclooxygenases And Monoacylglycerol Lipase In Neuropathic Pain, Molly S. Crowe

Graduate Theses, Dissertations, and Problem Reports (ETD)

Neuropathic pain is caused by altered nerve function that often presents as allodynia, which is the painful perception of typically non-noxious stimuli. Neuropathic pain is commonly treated with GABA analogues, steroids, or non-steroidal anti-inflammatory drugs (NSAIDs). NSAIDs inhibit one or more cyclooxygenase (COX) enzymes and are effective, commonly used analgesics that have relatively fewer side effects than other treatments. However, chronic cyclooxygenase inhibition also causes gastrointestinal inflammation and increased risk of cardiac events. Like NSAIDs, cannabinoids have analgesic and anti-inflammatory properties and reduce neuropathic pain in preclinical models. The present study investigated the analgesic effects of inhibiting both monoacylglycerol lipase …

Empathic Accuracy And Aggression In Couples: Individual And Dyadic Links, Shiri Cohen, Marc S. Schulz, Sabrina R. Liu, Muhannad Halassa, Robert J. Waldinger

Psychology Faculty Research and Scholarship

This study examined links between intimate partner aggression and empathic accuracy – how accurately partners can read one another’s emotions – during highly affective moments from couples’ (N = 109) video recall of laboratory-based discussions of upsetting events. Less empathic accuracy between partners was generally related to higher levels of aggression by both partners. More specific patterns emerged based on the type of aggression and emotion being expressed. Women’s poorer ability to read their partners’ vulnerable and positive emotions was linked to both men’s and women’s greater physical and psychological aggression. Moreover, women’s inaccuracy in reading their partner’s hostility was …

Low-Impact Infrastructure: Development And Design Potential For Surface Application Alternatives For Subsurface Infrastructure In Yellowstone National Park's Upper Geyser Basin, Michael R. Pace

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

In sensitive and iconic landscapes, such as Yellowstone National Park’s Upper Geyser Basin, construction and expansion of visitor services is hindered, and often blocked, by the potential for environmental damage that could occur during the installation of subsurface utilities. These utilities, crucial to the success of development, require an alternative method of installation when placed in locations requiring special consideration and protection.

Yellowstone, in particular, is faced with the responsibility of protecting limited hydrothermal resources while also providing access to the general public. Sub-surface utilities threaten this responsibility due to the unknown nature of much of the subsurface
