Cyberspace And Real-World Behavioral Relationships: Towards The Application Of Internet Search Queries To Identify Individuals At-Risk For Suicide, Casey C. Miller
Cyberspace And Real-World Behavioral Relationships: Towards The Application Of Internet Search Queries To Identify Individuals At-Risk For Suicide, Casey C. Miller
Theses and Dissertations
The Internet has become an integral and pervasive aspect of society. Not surprisingly, the growth of ecommerce has led to focused research on identifying relationships between user behavior in cyberspace and the real world - retailers are tracking items customers are viewing and purchasing in order to recommend additional products and to better direct advertising. As the relationship between online search patterns and real-world behavior becomes more understood, the practice is likely to expand to other applications. Indeed, Google Flu Trends has implemented an algorithm that accurately charts the relationship between the number of people searching for flu-related topics on …
Comparative Analysis Of Two Biological Warfare Air Samplers Using Live Surrogate Agents, James C. Enderby
Comparative Analysis Of Two Biological Warfare Air Samplers Using Live Surrogate Agents, James C. Enderby
Theses and Dissertations
The United States Air Force has several high-volume biological air samplers, including the XMX/2L-MIL and the Biocapture 650. Limited information is available on either in terms of its collection of viruses and bacteria. However, previous research on the XMX/2L-MIL has determined that modifications to the secondary flow rate and the use of a virus preserving collection media may provide improved virus collection rates. In this thesis, these modifications were investigated to determine their impact on the collection of viral and bacterial aerosols. Additionally, relative collection rates were compared against those for the Biocapture 650. MS2 bacteriophage was the viral surrogate …
Probabilistic Model For Laser Damage To The Human Retina, David R. Wooddell
Probabilistic Model For Laser Damage To The Human Retina, David R. Wooddell
Theses and Dissertations
Understanding how lasers interact with media during propagation is a premiere field of physics. The subject area known as laser bioeffects explores laser interactions with biological cells, tissues, organs, and bodies. This research includes laser applications used in medicine, establishes safe exposure limits for industry and academia, and generally studies the many effects of laser light on living creatures. The bioeffects community relies heavily on deterministic modeling and simulation tools to support experimental research into damage thresholds and laser effects. However, recent laser applications require a probabilistic approach to support risk management and analyses methodologies. Some probabilistic models exist, but …
Influence Of Ph On The Transport Of Silver Nanoparticles In Saturated Porous Media: Laboratory Experiments And Modeling, Jason R. Flory
Influence Of Ph On The Transport Of Silver Nanoparticles In Saturated Porous Media: Laboratory Experiments And Modeling, Jason R. Flory
Theses and Dissertations
Given the ubiquity of silver nanoparticles (AgNPs), the largest and fastest growing category of nanomaterials, and their potential for toxic effects to both humans and the environment, it is important to understand their environmental fate and transport. The purpose of this study is to gain information on the transport properties of unmodified AgNP suspensions in a glass bead-packed column under saturated flow conditions at different solution pH levels. Commercial AgNPs were characterized using high resolution transmission spectroscopy (HRTEM), dynamic light scattering (DLS) and ultraviolet (UV) visible spectroscopy. Transport data were collected at different pH levels (4, 6.5 and 9) at …
The Effects Of Cognitive-Behavioral Motivation For Health Improvement On Anthropometric Measurements In High Risk Individuals, Aimee T. Kirchner
The Effects Of Cognitive-Behavioral Motivation For Health Improvement On Anthropometric Measurements In High Risk Individuals, Aimee T. Kirchner
Theses and Dissertations
Unhealthy lifestyles cost businesses, governmental organizations, and the United States military billions of dollars every year. To fight this rising cost as well as potentially save lives this study sought to understand if a cognitive-behavioral motivation treatment could positively affect the cognitive variables (attitude, self-efficacy, and locus of control) that induce long term behavior change. Anthropometric measurements, specifically body mass index, abdominal circumference, and abdominal height, were used to determine if long term behavior change resulted from the treatment. The Theory of Planned Behavior was the basis of this thesis' model, while the Valence, Instrumentality, and Expectancy (VIE) theory was …
A Proposed Mediation Model Of The Effects Of Motivation For A Healthy Lifestyle: Impacts On Emotional Exhaustion, Medication Regimens, And Low-Density Lipoprotein, Nathan M. Leuthold
A Proposed Mediation Model Of The Effects Of Motivation For A Healthy Lifestyle: Impacts On Emotional Exhaustion, Medication Regimens, And Low-Density Lipoprotein, Nathan M. Leuthold
Theses and Dissertations
This research addressed the following question: "How are behavioral indicators related to physiological responses?" Three theories -- Conservation of Resources, Planned Behavior, and Achievement Motivation -- were employed to build a proposed model of the effects that an individual's motivation for a healthy lifestyle would have on his/her emotional exhaustion, daily medication usage, and low-density lipoproteins. Motivation for a healthy lifestyle was hypothesized to have a negative relationship with emotional exhaustion when using body mass index as a partial mediator. Emotional exhaustion was hypothesized to have positive relationships with daily medication usage and low-density lipoproteins. The model was tested using …
