Impacts Of Environmental Conditions On Fleas In Black-Tailed Prairie Dog Burrows, Julia E. Poje, Tonie Rocke, Michael D. Samuel

United States Geological Survey: Staff Publications

Sylvatic plague, caused by the bacterium Yersinia pestis and transmitted by fleas, occurs in prairie dogs of the western United States. Outbreaks can devastate prairie dog communities, often causing nearly 100% mortality. Three competent flea vectors, prairie dog specialists Oropsylla hirsuta and O. tuberculata, and generalist Pulex simulans, are found on prairie dogs and in their burrows. Fleas are affected by climate, which varies across the range of black-tailed prairie dogs (Cynomys ludovicianus), but these effects may be ameliorated somewhat due to the burrowing habits of prairie dogs. Our goal was to assess how temperature and precipitation …

How Do Monetary Incentives Influence Prosocial Fundraising? An Empirical Investigation Of Matching Subsidies On Crowdfunding, Zhiyuan Gao

Dissertations and Theses Collection (Open Access)

Monetary incentives, such as matching subsidies, are widely used in traditional fundraising and crowdfunding platforms to boost funding activities and improve funding outcomes. However, its effectiveness on prosocial fundraising is still unclear from both theoretical (Bénabou and Tirole, 2006; Frey, 1997; Meier, 2007a) and empirical studies (Ariely et al., 2009; Karlan and List, 2007; Rondeau and List, 2008). This dissertation aims to examine the effectiveness of matching subsidies on prosocial fundraising in the crowdfunding context. Specifically, I study how the presence of matching subsidies affects overall funding outcomes and funding dynamics in the online prosocial crowdfunding environment.

Albion Through Malleable Eyes: The Great Migration, Urban Renewal And Missed Opportunities, Demetrius R. Goodale

Masters Theses

Albion, Michigan’s African American community built a robust, diverse, and thriving city in the early 20th century. Jobs were plentiful and wages allowed for healthy communities to sprout up across the city’s landscape. During this period Albion’s overall population more than doubled, and its African American community grew exponentially over the course of six decades. However, for many in the African American community, societal and economic gains were overshadowed by a crippling shortage in viable housing options. Albion’s African American community experienced limited options to help remedy the community’s housing challenges. These limitations were due to discriminatory housing norms and …

Assessment Of Dopaminergic And Serotonergic Receptor Antagonists In Male Rats Trained To Discriminate 4-Methylmethcathinone (Mephedrone), Rachel L. Burroughs

Masters Theses

Preclinical drug discrimination studies of the synthetic cathinone, 4-methylmethcathinone (mephedrone) have demonstrated its effects are comparable to those of other popular psychostimulant drugs. Few studies have directly examined the contribution of specific neurotransmitter receptors to mephedrone’s discriminative stimulus effects. The present study investigated the role of dopamine and serotonin receptors in these effects. Eight adult male Sprague-Dawley rats were trained to discriminate 3.0 mg/kg mephedrone from saline. After dose-response curves were determined with mephedrone (0.375-3.0 mg/kg), a series of stimulus antagonism tests were conducted with dopamine antagonists (Sch 23390, haloperidol) and serotonin antagonists (WAY 100,635, MDL 100,907, pirenperone) administered as …

Exploring The Niche Of Rickettsia Montanensis (Rickettsiales: Rickettsiaceae) Infection Of The American Dog Tick (Acari: Ixodidae), Using Multiple Species Distribution Model Approaches, Catherine A. Lippi, Holly Gaff, Alexis L. White, Heidi K. St. John, Allen L. Richards, Sadie J. Ryan

Biological Sciences Faculty Publications

The American dog tick, Dermacentor variabilis (Say) (Acari: Ixodidae), is a vector for several human diseasecausing pathogens such as tularemia, Rocky Mountain spotted fever, and the understudied spotted fever group rickettsiae (SFGR) infection caused by Rickettsia montanensis. It is important for public health planning and intervention to understand the distribution of this tick and pathogen encounter risk. Risk is often described in terms of vector distribution, but greatest risk may be concentrated where more vectors are positive for a given pathogen. When assessing species distributions, the choice of modeling framework and spatial layers used to make predictions are important. …

Risk Factors Contributing To The Development Of Bronchopulmonary Dysplasia Among Preterm Infants, Caitlin E. Bradley

Graduate Doctoral Dissertations

Bronchopulmonary dysplasia (BPD) is a pulmonary disease that affects infants born < 32 weeks gestational age. Despite improved survival among preterm infants, the incidence and severity of BPD has not improved, rather the features and severity of BPD have evolved (Abman et al., 2017). BPD is a disease that has significant impact on the outcomes of preterm infants, including poor pulmonary and neurodevelopmental outcomes (Abman et al., 2017). Since its identification in 1967, and many iterations to its defining criteria, healthcare practitioners are unable to accurately predict infants’ risk of developing BPD. Further, there is significant family, social, and economic impacts from BPD. This dissertation research examined risk factors for BPD, as identified in a mid-range theory developed from a systematic review of the literature. This mid-range theory is framed using the Neuman Systems Model (NSM) (2011). The research utilized a secondary analysis of data from a database including a cohort of infants born at < 32 weeks’ gestation (n=455) treated at Boston Children’s Hospital. Findings from this research demonstrated that multiple intrapersonal risk factors are associated with development of BPD and the grades of BPD severity including gestational age, birth weight, surfactant administration, necrotizing enterocolitis, infections, mechanical ventilation duration, and patent ductus arteriosus. This research adds to the current body of research by demonstrating specific risks associated with BPD. Findings of this research could be used to identify maternal infant dyads that would benefit from early therapy(s) to reduce BPD risk.

We focus on benthic monitoring that took place within the BIWF. This monitoring allowed for assessments of spatiotemporal changes in sediment grain size, organic enrichment, and macrofauna, as well as the colonization of the jacket structures, up to four years post-installation. The greatest benthic modifications …

Robust Maximum Coverage Facility Location Problem With Drones Considering Uncertainties In Battery Availability And Consumption, Darshan Chauhan, Avinash Unnikrishnan, Miguel Figliozzi, Stephen D. Boyles

Civil and Environmental Engineering Faculty Publications and Presentations

Given a set of spatially distributed demand for a specific commodity, potential facility locations, and drones, an agency is tasked with locating a prespecified number of facilities and assigning drones to them to serve the demand while respecting drone range constraints. The agency seeks to maximize the demand served while considering uncertainties in initial battery availability and battery consumption. The facilities have a limited supply of the commodity being distributed and also act as a launching site for drones. Drones undertake one-to-one trips (from located facility to demand location and back) until their available battery energy is exhausted. This paper …

Taxes As Pandemic Controls, Ashley C. Craig, James R. Hines Jr.

Articles

Tax policy can play important roles in limiting the spread of communicable disease and in managing the economic fallout of a pandemic. Taxes on business activities that bring workers or customers into close contact with each other offer efficient alternatives to broad regulatory measures, such as shutdowns, that have been effective but enormously costly. Corrective taxation also helps raise the revenue required to cover elevated government expenditure during a pandemic. Moreover, the restricted consumer choice that accompanies a pandemic reduces the welfare cost of raising tax revenue from higher-income taxpayers, making it a good time for deficit closure. Current U.S. …

An Association Between Perceived Social Support And Posttraumatic Stress Symptom Severity Among Women With Lifetime Sexual Victimization: The Serial Mediating Role Of Resilience And Coping, Michiyo Hirai, Ruby Charak, Laura D. Seligman, Joseph D. Hovey, John M. Ruiz, Timothy W. Smith

Psychological Science Faculty Publications

This study examined the association between perceived social support and severity of posttraumatic stress symptoms, serially mediated by resilience and coping among women exposed to different patterns of sexual victimization experiences: childhood sexual abuse (CSA) only, adult sexual assault (ASA) only, and sexual revictimization (SR). A total of 255 sexually victimized women recruited from four U.S. universities completed self-report measures online; 112 participants reported provisionally diagnosable levels of symptoms of posttraumatic stress disorder (PTSD). The proposed model was largely supported in the CSA only group and the SR group. Different patterns of mediational effects were found across the three groups. …

Rethinking Resource Allocation: Fairness And Computability, Andrew Searns

Theses

In the field of multiagent systems, one important problem is fairly allocating items among a set of agents. The gold standard fairness property is envy-freeness whereby each agent prefers the bundle allocated to them over any other bundle. For indivisible goods, envy-freeness cannot be guaranteed: consider two agents and one item. In the context of indivisible goods, one key fairness notion which has gained significant attention in recent years is the maximin share guarantee (MMS). MMS extends the cut-and-choose protocol to multiple agents by guaranteeing each agent as much value as if they divided items into bundles but chose last. …
