Delay Discounting And Cannabinoid Enzyme Inhibitors, Devin Andrew Galdieri
Delay Discounting And Cannabinoid Enzyme Inhibitors, Devin Andrew Galdieri
Graduate Theses, Dissertations, and Problem Reports (ETD)
Delay discounting is a measure of impulsive choice that is correlated with maladaptive behavior and psychological disorders. Disruptions to serotonin and dopamine pathways can cause changes in delay discounting, as can lesions to the prefrontal cortex and nucleus accumbens. The endocannabinoid system modulates other neurotransmitter systems, including dopamine and serotonin pathways. Cannabinoid receptors type 1 are found in relatively high concentrations in the nucleus accumbens and the prefrontal cortex. These receptors are activated by endogenous cannabinoids, which are synthesized on demand and broken down by catabolic enzymes. The action of these enzymes can be inhibited by a class of drugs …
Schmick’S Frontier: Native American And Moravian Community Building In Colonial Pennsylvania, 1753-1765, Megan Trent Mcgee
Schmick’S Frontier: Native American And Moravian Community Building In Colonial Pennsylvania, 1753-1765, Megan Trent Mcgee
Graduate Theses, Dissertations, and Problem Reports (ETD)
This dissertation explores community building during times of violence. I argue that the intense violence in Colonial Pennsylvania during the 1750s and 1760s did not prevent the Moravians from building multi-ethnic communities, even as other groups (French, British, and Iroquois) pursuing their own political gains sought to tear such communities apart. The project focuses on community building and cohesion during a time of violence. Both the Moravians and the Native Americans were marginalized outsiders in mid-eighteenth-century Pennsylvania. The Moravians were outsiders because they were Europeans who failed to integrate culturally with their European neighbors. The Delaware, Mohicans, and smaller Native …
Effects Of Reinforcement Rate On The Aversive Function Of Timeout From Positive Reinforcement, Cory Whirtley
Effects Of Reinforcement Rate On The Aversive Function Of Timeout From Positive Reinforcement, Cory Whirtley
Graduate Theses, Dissertations, and Problem Reports (ETD)
Although the use of timeout from positive reinforcement is widespread and has been shown to be an effective punisher in clinical settings, the factors responsible for its effectiveness are not fully understood. The present experiment was designed to evaluate one of these factors, the reinforcement rate underway during periods of time-in. Rats’ lever pressing was maintained on variable-interval schedules of food reinforcement in a multiple schedule with two components. In one component, no timeouts were delivered. In the other component, when a variable-ratio schedule was met, lever presses were followed by a 30-s timeout during which a tone sounded, the …

An Interspecies Investigation Of Thyroid Plasma Hormone Concentrations, Histology, And Gene Expression, Emily A. Underwood
Graduate Theses, Dissertations, and Problem Reports (ETD)
A high prevalence of endocrine disrupting chemicals (EDCs) in Great Lakes Areas of Concern (AOCs) has raised concerns as to the health and fitness of fish and wildlife. It is not well understood to what extent existing contaminants, many with continuing inflows into the environment, may impact fish populations. This study provides an initial characterization of thyroid endocrine-related effects in two indigenous fish species sampled from Great Lakes AOCs. Biomonitoring was conducted on a pelagic, top predator species, smallmouth bass (Micropterus dolomieu) and benthic, omnivorous brown bullhead (Ameiurus nebulosus) at 7 sites in spring and fall …
Analysis Of Dimensionless Scaling Relationships For Rotating Free Flight Bodies, Shawn A. Smearcheck
Analysis Of Dimensionless Scaling Relationships For Rotating Free Flight Bodies, Shawn A. Smearcheck
Graduate Theses, Dissertations, and Problem Reports (ETD)
Though more obscure than traditional flight analysis, the tendency for a rigid body to flutter or tumble in flight during unstable conditions has been analyzed through physical experiments since the 1960s. In more recent years, similar conditions have been subjected to numerical simulation to further understand the effects of dimensionless properties on unstable body motion. It is important to understand dimensionless scaling relationships to compare properties of a body to that of a scaled model or for adjusting data when manufacturing limitations exist. For example, if the geometry of a scaled object could easily be manufactured, within tolerance, but material …

Watching You Watching Me: Lateral Surveillance In Singapore, Yan Song Lee
Watching You Watching Me: Lateral Surveillance In Singapore, Yan Song Lee
Graduate Theses, Dissertations, and Problem Reports (ETD)
Historically, top-down surveillance -- surveillance from the state and other organizations -- has dominated social life, but not anymore. Technological advances drove down the price of surveillance equipment which aided in the proliferation of devices such as dashboard cameras. The widespread use of affordable surveillance equipment gave rise to the phenomenon of lateral surveillance, whereby laypersons can employ surveillance techniques to monitor individuals around them. The Singapore metropolis provides an excellent example with the ubiquitous use of dashboard cameras for cars today. In this research, I focus on Singaporean rideshare drivers who are simultaneously subjected to traditional forms of top-down …
Beef Cattle Effluent Treatment In A Denitrifying Bioreactor., Bethani Chambers
Beef Cattle Effluent Treatment In A Denitrifying Bioreactor., Bethani Chambers
Graduate Theses, Dissertations, and Problem Reports (ETD)
Excess nutrient runoff, nitrates and phosphates, has led to the development of algal blooms and hypoxic zones worldwide. Based on a report from the Chesapeake Bay Foundation nearly half of all nutrient sources originate from agricultural production with a quarter of this resulting from improper management of manures. This project focuses on a novel adaption of a denitrifying bioreactor, which has demonstrated removals of agricultural nutrients, which may have implications on the treatment of manure nutrients. These subsurface bioreactors work by providing a substrate, usually wood based, to act as a carbon source to support denitrifying bacteria which in turn …
Choice Dynamics In Concurrent Ratio Schedules Of Reinforcement, Daniel Bell-Garrison
Choice Dynamics In Concurrent Ratio Schedules Of Reinforcement, Daniel Bell-Garrison
Graduate Theses, Dissertations, and Problem Reports (ETD)
Roughly 50 years of research has demonstrated that choice changes as a function of the amount of reinforcement available from two concurrently available schedules of reinforcement, and this function has been labeled the generalized matching law. The matching law, however, historically only accounts for choice between two variable-interval schedules of reinforcement. If the matching law is to be a general perspective for how organisms allocate behavior amongst several alternatives, then it ought to account for behavior when reinforcers depend on work requirements in addition to time requirements. To study these contexts, the present experiments employed concurrent ratio schedules that were …
Investigation Into Composting Efforts At Wvu: A Case Study., Marina Alexis Berry
Investigation Into Composting Efforts At Wvu: A Case Study., Marina Alexis Berry
Graduate Theses, Dissertations, and Problem Reports (ETD)
Institutional composting systems have been adopted by many land grant universities to help better manage their waste and protect the environment. West Virginia University (WVU) has yet to begin formally managing their animal manure and waste at the university farms. This investigation will look into what has been done at other land grant universities to see which methods could be applied at WVU. This could have environmental, economic, and social benefits and also serve as a living learning classroom. University composting systems have often started small and grown to accommodate campus food waste, which could also be a possibility for …

Assessment Of Melanistic Lesions In Smallmouth Bass ( Micropterus Dolomieu) Of The Chesapeake Bay, Usa, Kelsey T. Young
Assessment Of Melanistic Lesions In Smallmouth Bass ( Micropterus Dolomieu) Of The Chesapeake Bay, Usa, Kelsey T. Young
Graduate Theses, Dissertations, and Problem Reports (ETD)
Smallmouth bass (Micropterus dolomieu) are an important sportfish in the Susquehanna and Potomac River Basins of the Chesapeake Bay drainage. However, population declines in portions of the Susquehanna, fish kills and reports of visible abnormalities such as melanistic spots have raised concern among the public and resource managers. Although the etiology or risk factors associated with melanistic lesions are unknown, there is a propensity to attribute the abnormality to contaminants. Melanistic lesions of smallmouth bass were assessed using histopathology and gene expression analysis to evaluate the cellular and molecular changes compared to normal skin. The prevalence of melanistic …
"Squeezed Between The Gunshots And The Gentrifiers”: Urban Agriculture In Philadelphia's Kensington Neighborhood, Arianna Hall-Reinhard
"Squeezed Between The Gunshots And The Gentrifiers”: Urban Agriculture In Philadelphia's Kensington Neighborhood, Arianna Hall-Reinhard
Graduate Theses, Dissertations, and Problem Reports (ETD)
Urban agriculture (UA) is part of the broader alternative food movement and a potential avenue through which to “do” food justice work. UA projects in the urban Global North are frequently motivated by social and food justice goals. Despite these guiding ideals, UA projects in America are rife with internal contradictions, including those related to racial inequalities, complex gentrification dynamics, and funding realities. In this paper, I employ the conceptual frameworks of food justice and urban political ecology to consider how gentrification and UA project funding structures affect five specific UA projects in Philadelphia’s Kensington neighborhood. While the loss of …
Understanding Transgender Prejudice Through The Lens Of Emotion, Holly N. Fitzgerald
Understanding Transgender Prejudice Through The Lens Of Emotion, Holly N. Fitzgerald
Graduate Theses, Dissertations, and Problem Reports (ETD)
Transgender individuals report facing incidents of discrimination often in all aspects of their lives (James et al., 2016). A potential way to combat the discrimination transgender people face is through reducing transgender prejudice. However, it is not yet known what comprises transgender prejudice. Some research has found that emotions may be the more predominant determinant of prejudice, as opposed to stereotypes (Dasgupta, Desteno, Williams, & Hunsinger, 2009; Haddock, Zanna, & Esses, 1993a; Smith, 1993). Thus, the present research sought to identify the specific emotions associated with transgender prejudice. In Study 1, participants completed explicit and implicit measures of prejudice and …

A Lab-Based Study Of N95 Ffrs Against Cigarette Smoke Under Varying Concentrations And Sealing Conditions, Jacob Davis
Graduate Theses, Dissertations, and Problem Reports (ETD)
Respirators are a common form of protection when working in environments where workers are exposed to harmful agents. One exposure that has not been rigorously tested is cigarette smoke. Air sampling was conducted to test the effectiveness of four different respirators N95 Respirators for various concentrations of cigarette smoke and seal conditions and for different respirators. The Moldex 2200, Moldex 2300 (exhalation valve), Gerson 1730, and 3M 8210V (Exhalation valve) were used for testing. The set concentrations were 100,000: 200,000: and 400,000 cm3 with an error allowance of 20% for each concentration. Different flow rates (15, 30, 50, and 85 …
