Evaluating Recommendations Versus Utilization Of Essential Components Of A Functional Analysis Procedure, Alissa Conway

Dissertations

Functional behavior assessment (FBA) has been identified as an essential process for behavior analytic practitioners to identify the variables maintaining challenging behaviors (BACB Professional and Ethical Compliance Code for Behavior Analysts (PECC), 3.01ab, 2014). FBAs include a range of strategies, including indirect measures (e.g., interviews and questionnaires) and direct measures of behavior (descriptive and experimental strategies). Functional analysis (FA) is typically considered the most sophisticated of the options subsumed under FBAs in that it involves both direct measures of behavior and experimental manipulation of hypothesized controlling variables to identify controlling variables for challenging behaviors. The results of FAs allow practitioners …

An Improved Method For The Analysis Of Fiber Evidence Using Polarized Light Microscopy, Samuel F. Kaplan

Student Theses

Using the basic fundamentals of polarized light microscopy, a new and improved method for identifying synthetic fibers is presented in this thesis. Using the equation of an ellipse in spherical coordinates, an EXCEL™ (Microsoft Inc., Seattle, WA) spreadsheet was developed that generated tables of data that provide a foundation for a new and more efficient method in fiber analysis. Intermediate refractive index values for each subclass of textile fibers were calculated based on the fiber's principal refractive index values. The angles of refractive index matching to known refractive index fluids vary from 0 to 90 degrees upon rotation of the …

A Climatology Of Precipitation Days Throughout The Continguous United States, Rudy J. Bartels

LSU Doctoral Dissertations

Over the last century, scientists have raised questions about climate change and one of the more important variables that may undergo change is precipitation. Precipitation can affect many sectors including agriculture, socio-economic activities and hazard management. This dissertation addresses the temporal aspect of precipitation using 167 first order stations in the contiguous United States from 1951-2015. The three objectives of this dissertation are to perform (1) an annual analysis of the frequency of rain days in the United States and changing magnitudes of daily rainfall, (2) seasonal rain day frequency in the United States, and (3) use an artificial neural …

Utilization Of Digital Image Correlation Technique In Asphalt Testing, Alejandra Escajeda

Open Access Theses & Dissertations

Over 90% of the roads in the United States are paved with hot mix asphalt (HMA). These asphalt pavements include many mix types, such as permeable friction course (PFC), stone mastic asphalt (SMA) and conventional dense graded mixes. The performance of the HMA is an important factor in pavement design programs used by many departments of transportation. The type of HMA selected not only influences the performance of the pavement structure, but also the pavement's life cycle cost. The performance life of an HMA mix is to be studied further with experimental data in order to contribute and expand on …

Analysis Of Evacuation Behaviors And Departure Timing For October 2016’S Hurricane Matthew, Erika O. Pham

Theses and Dissertations

During a hurricane, an individual’s risk perception does not remain static. Spatial and temporal variations of a hurricane will shift perceptions of risk, and complicating this dynamic are information-seeking processes increasingly reliant on the individual’s self-motivated interpretation of information sources. Initial evacuation resistance or willingness could change even after evacuations are ordered, affecting evacuation preferences and departure times. Because Hurricane Matthew’s continually shifting track had virtually nonstop coverage, evacuation decisions were also being modified as residents either grew more or less certain of their safety.

This research investigates the evacuation behaviors associated with Hurricane Matthew in October of 2016. It …

An Economic Framework Of Collective Action During The Korean War, Nicole C. Ruiz

Open Access Theses & Dissertations

Collective action, the coordinated effort between multiple actors, continues to play a role in the international community. In an increasingly complex operational environment, understanding the dynamics of these coordinated efforts is necessary for intelligence analysts. This research seeks to address the question: How can economic methodology be used to understand collective action during the Korean War for future use in intelligence analysis? The Korean War consisted of two different collective action groups going against each other militarily and ultimately diplomatically, which is why it is a suitable case study for understanding the nature of collective action. The research provides an …
