Dynamic Behavior And Player Types In Majoritarian Multi-Battle Contests, Alan Gelder, Dan Kovenock

ESI Working Papers

In a dynamic contest where it is costly to compete, a player who is behind must decide whether to surrender or to keep fighting in the face of bleak odds. We experimentally examine the game theoretic prediction of last stand behavior in a multi-battle contest with a winning prize and losing penalty, as well as the contrasting prediction of surrendering in the corresponding contest with no penalty. We find varied evidence in support of these hypotheses in the aggregated data, but more conclusive evidence when scrutinizing individual player behavior. Players’ realized strategies tend to conform to one of several “types”. …

Manchester Snow Emergency Analysis: Who Is Being Towed From Where And Why, Michael James Pelletier

Master's Theses and Capstones

This Capstone paper analyzes the City of Manchester, New Hampshire’s policy and community impacts when their Towing Snow Emergency procedures are implemented. While the public expects their city streets and sidewalks to be cleared of snow during and following snow storms, the process to do so in the city streets requires vehicles to be re-located from parking on the street. This process requires privately owned vehicles to be ticketed or towed during the worst of weather during the winter. Although the city administration has attempted to avoid having to tow vehicles as the report shows, there is still a historical …

Inefficiency In The Post Anesthesia Care Unit: A Quality Improvement Initiative, Ashley St. Martin

Master's Theses and Capstones

Background: The post anesthesia care unit (PACU) is a busy environment in which nurses communicate with patients, family members, and a large team of perioperative professionals. PACU nurses were experiencing an unmanageable number of work interruptions due to a higher patient census which increased the daily surgical caseload.

Aim: The purpose of this project was to improve efficiency and nurses’ job satisfaction by making work interruptions manageable in the PACU.

Methods: Based on Kotter’s Change Theory, a quality improvement initiative was implemented using a change in the communication process. Qualitative and quantitative data was gathered in the PACU and on …

High-Frequency Broadband Seafloor Backscatter In A Sandy Estuarine Environment, Eric J. Bajor

Master's Theses and Capstones

Seafloor backscatter collected with high-frequency (> 100 kHz) hydrographic echosounders has become an important aspect of seafloor characterization for benthic ecologists and other scientists. The mechanisms that control acoustic scattering at these high frequencies are not completely understood, although surficial roughness and the presence of discrete particles (e.g., shell hash) are likely contributors. To further our understanding of the impact these mechanisms have on seafloor scattering, broadband (100-250 kHz) acoustic measurements were taken at a grazing angle of 45° in a shallow-water, sandy environment with a known presence of shell hash. Stereo imagery was collected simultaneously to quantify the surficial …

Using Shock Index As A Predictor Of Icu Readmission: A Quality Iimprovement Project, Melissa Sykes

Master's Theses and Capstones

Background: Adverse events will occur in one-third of patients discharged from the intensivecare unit (ICU) and evidence shows that ICU readmissions increase a patient’s length of stay,
mortality, hospital costs, and nosocomial infections, as well as decrease long-term survival.Specific predictive factors that will accurately predict which patients are at risk of adverseevents requiring readmission are needed.Aim: The specific aim of this project was to identify if shock index (SI) values higher than 0.7at the time of transfer from the ICU are a useful predictor of ICU readmission.Methods: Using the Plan, Do, Study, Act (PDSA) framework, a retrospective chart review wasperformed …

These devices are now important tools contributing to a “culture of safety” defined by the Joint Commission. Reports from April 2015 indicated a 22% occurrence rate in which the devices were not correctly programmed before infusion.

AIM Statement: The global aim of this quality improvement project was to improve usage of the IV pump drug library by ensuring medication is correctly labeled before infusion. The specific aim was to increase the …

Prevention Of Icu Delirium Through Implementation Of A Sleep Promotion Bundle, Victoria Bennett

Master's Theses and Capstones

Background: Intensive care unit (ICU) delirium is the prevalence of delirium in ICU patientswho do not have a history of drug/alcohol abuse, an admission for a mental status change, or anadmission to the ICU for less than 24 hours. Serious adverse outcomes have been linked to thepresence of ICU delirium resulting in overall longer hospital lengths of stay, longer duration ofmechanical ventilation, higher rates of mortality, and long-term neuropsychological deficits afterdischarge. At the site of this quality improvement project, the prevalence of ICU delirium was92.3% in a population determined to be high risk using the PRE-DELIRIC screening tool. Aim: The …

A Culturally Appropriate Cognitive Assessment Screening For Bhutanese Refugees, Holly Milligan

Master's Theses and Capstones

Background: As the incidence of cognitive impairment continues to rise, timely and accuratediagnoses are essential. Aim: The aim of this quality improvement project was to evaluate the standard cognitiveassessment screening for Bhutanese refugees in a medical home, and compare an alternative,validated, and potentially more culturally appropriate tool. Also, an assessment of provider,nurse and interpreter satisfaction with the two tools was performed. Method: Mixed methods including qualitative observations and quantitative satisfaction surveysrelated to the implementation of a culturally appropriate cognitive assessment tool.

Be Seen And Heard Being Clean: A Patient-Centered Approach To Hand Hygiene At Concord Hospital, Ashley Pinkham

Master's Theses and Capstones

Background: Regular hand washing is recognized as the most effective means to combat the spread of infectious illness; however hand washing behavior amongst health care workers (HCW’s) is inconsistent. Furthermore, measurement of hand washing behavior is subject to bias.

Aim: This quality improvement project aimed to remove the Hawthorne effect and improve the behavior of HH at Concord Hospital.

Methods: A quasi-experimental, pre-posttest design was used to evaluate HH rates on a 32 bed med-surge unit at Concord Hospital. Baseline data was collected for 30 days by asking patients if they had seen or heard staff cleaning their hands. Using …

Implementing A Checklist & Hourly Huddles To Increase Situational Awareness During The Second Stage Of Labor-A Perinatal Quality Improvement Project, Kelly Knowles

Master's Theses and Capstones

Background: Current management of the second stage of labor often follows tradition-based routines rather than evidence-based practices. A lack of situational awareness and tunnel vision can limit medical decision-making. Northern New England Perinatal Quality Improvement Network (NNEPQIN) has listed Second Stage Situational Awareness as a priority initiative. Standardized checklists are useful for maintaining situational awareness. Regular debriefings using a standardized tool have been shown to improve communication and team based care, which generally leads to improved patient outcomes. Based on this evidence, developing a standardized checklist including regular hourly care team “huddles” is valuable and could result in improved birth …

City Profile Of Richmond, Julian Maxwell Hayter

Jepson School of Leadership Studies articles, book chapters and other publications

Cities are never blank slates. Every urban ranking and rating begs acknowledgement of lasting cultural legacies and histories. It is essential that any quantitative assessment not stand outside of context. At stake is the difference between possessing sheer quantities of information, on the one hand, and quality knowledge, or wisdom, on the other. In order to put data into a context for wise action, Thriving Cities has created distinct city profiles for its pilot cities.

These profiles are central in that they characterize a given pilot city in relation to the Project's distinctive "human ecology" framework and research design. In …

Review Of Sovereign Defaults Before International Courts And Tribunals, John A. E. Pottow, Emily Iversen

Reviews

This book review probes Michael Waibel’s new book, Sovereign Defaults Before International Courts and Tribunals. Waibel's project is ambitious, exploring international attempts to address sovereign defaults over the past century and a half. Through painstaking and comprehensive historical analysis, Waibel shows how we've been here before -- a sober reminder for those thinking Argentina is simply part of a new fad in financial default. With the UN now turning its attention to sovereign debt issues, this study is especially timely. Although somewhat disappointing in the lightness of its normative content, the book should nevertheless prove helpful to those considering the …

Ethical Decision Making And Leadership: Merging Social Role And Self-Construal Perspectives, Crystal L. Hoyt, Terry L. Price

Jepson School of Leadership Studies articles, book chapters and other publications

This research extends our understanding of ethical decision making on the part of leaders by merging social role and self-construal perspectives. Interdependent self-construal is generally seen as enhancing concern for justice and moral values. Across two studies we tested the prediction that non-leading group members’ interdependent self-construal would be associated with lower levels of unethical decision making on behalf of their group but that, in contrast, this relationship would be weaker for leaders, given their social role. These predictions were experimentally tested by assigning participants to the role of leader or non-leading group member and assessing the association between their …

Development Of 3-D Shear Wave Models Using A Multi-Objective Optimization Scheme, Lennox Emmanuel Thompson

Open Access Theses & Dissertations

Evidence of geologic activity still occurring in Rio Grande Rift (RGR) includes quaternary faulting, seismicity, and widening at a small rate. We map the crustal thickness and seismic velocity ratio to create crustal model cross sections that highlights the regional extension of the Southern Rio Grande Rift (SRGR). Specifically, we compute receiver functions and receiver function stacks for 147 USArray and previously collected data, and interpolate the crustal and velocity results using a kriging interpolation scheme. By incorporating gravity, magnetics, receiver functions, velocity models, and the interpretation of seismic reflection/refraction data, we produce a constrained crustal model that characterizes the …

The authors explore the representations and meanings of digital practices of public school students of a predominately working class neighborhood situated in the periphery of Buenos Aires, Argentina. Findings highlight different aspects of youth cultural consumption profile. Two themes were identified: a) children use computers for a multiplicity of different activities enacting multitasking practices; and b) …

Classroom Labels That Young Children Can Use: Enhancing Biliteracy Development In A Dual Language Classroom, Irasema Salinas-González, Iliana Alanis, María G. Arreguín-Anderson

Human Development and School Services Faculty Publications

This article focuses on biliteracy development of English and Spanish through the practical strategy of systematically labeling the classroom within the context of daily classroom activities and providing children with various opportunities to use the words throughout the day. Using the foundational work related to classroom labels from Pinnell and Fountas (1998, 2010), the authors adopt a definition indicating that a label consists of one or a few words on a card placed on or below an object or a spot in the classroom. Providing young dual language learners opportunities to use language in both the spoken and written form …

A Portable, Low-Cost Wheelchair Ergometer Design Based On A Mathematical Model Of Pediatric Wheelchair Dynamics, Jacob R. Rammer, Susan A. Riedel, Gerald F. Harris

Biomedical Engineering Faculty Research and Publications

Evaluation and training of wheelchair propulsion improves efficiency and prevents orthopaedic injury in pediatric manual wheelchair users. Ergometers allow static propulsion and emulate typical conditions. Currently available ergometers have deficiencies that limit their use in motion analysis. A new ergometer is developed and evaluated based on a model of wheelchair inertial dynamics that eliminates these deficiencies. This makes integrated motion analysis of wheelchair propulsion in current community, home, and international outreach efforts possible.

Technical Note: Phantom Study To Evaluate The Dose And Image Quality Effects Of A Computed Tomography Organ-Based Tube Current Modulation Technique, Diksha Gandhi, Dominic J. Crotty, Grant M. Stevens, Taly Gilat Schmidt

Biomedical Engineering Faculty Research and Publications

Purpose

This technical note quantifies the dose and image quality performance of a clinically available organ-dose-based tube current modulation (ODM) technique, using experimental and simulation phantom studies. The investigated ODM implementation reduces the tube current for the anterior source positions, without increasing current for posterior positions, although such an approach was also evaluated for comparison.

Methods

Axial CT scans at 120 kV were performed on head and chest phantoms on an ODM-equipped scanner (Optima CT660, GE Healthcare, Chalfont St. Giles, England). Dosimeters quantified dose to breast, lung, heart, spine, eye lens, and brain regions for ODM and 3D-modulation (SmartmA) settings. …

Virtual Capstone Design Teams: Preparing For Global Innovation (Journal Article), Jay R. Goldberg, Susannah Howe

Biomedical Engineering Faculty Research and Publications

Global innovation requires collaboration between groups of people located in different parts of the world, and is a growing trend in industry. Virtual teams are often used to manage new product development projects. These teams are similar to traditional teams but are geographically separated and rely heavily on virtual methods of communication (email, Skype, teleconferencing, etc.) instead of regular face-to-face meetings. Experience working as a member of a virtual capstone design team can help prepare students for this growing trend. To begin preparing students for work on virtual teams in industry, we co-advised two virtual capstone design projects with students …

Critical Changes In Cortical Neuronal Interactions In Anesthetized And Awake Rats, Anthony G. Hudetz, Jeannette A. Vizuete, Siveshigan Pillay, Kristina M. Ropella

Biomedical Engineering Faculty Research and Publications

Background: Neuronal interactions are fundamental for information processing, cognition, and consciousness. Anesthetics reduce spontaneous cortical activity; however, neuronal reactivity to sensory stimuli is often preserved or augmented. How sensory stimulus–related neuronal interactions change under anesthesia has not been elucidated. In this study, the authors investigated the visual stimulus–related cortical neuronal interactions during stepwise emergence from desflurane anesthesia.

Methods: Parallel spike trains were recorded with 64-contact extracellular microelectrode arrays from the primary visual cortex of chronically instrumented, unrestrained rats (N = 6) at 8, 6, 4, and 2% desflurane anesthesia and wakefulness. Light flashes were delivered to the retina …

Recent Developments In Osteogenesis Imperfecta, Joseph L. Shaker, Carolyne Albert, Jessica M. Fritz, Gerald F. Harris

Biomedical Engineering Faculty Research and Publications

Osteogenesis imperfecta (OI) is an uncommon genetic bone disease associated with brittle bones and fractures in children and adults. Although OI is most commonly associated with mutations of the genes for type I collagen, many other genes (some associated with type I collagen processing) have now been identified. The genetics of OI and advances in our understanding of the biomechanical properties of OI bone are reviewed in this article. Treatment includes physiotherapy, fall prevention, and sometimes orthopedic procedures. In this brief review, we will also discuss current understanding of pharmacologic therapies for treatment of OI.

Experimental Comparison Of Empirical Material Decomposition Methods For Spectral Ct, Kevin C. Zimmerman, Taly Gilat Schmidt

Biomedical Engineering Faculty Research and Publications

Material composition can be estimated from spectral information acquired using photon counting x-ray detectors with pulse height analysis. Non-ideal effects in photon counting x-ray detectors such as charge-sharing, k-escape, and pulse-pileup distort the detected spectrum, which can cause material decomposition errors. This work compared the performance of two empirical decomposition methods: a neural network estimator and a linearized maximum likelihood estimator with correction (A-table method). The two investigated methods differ in how they model the nonlinear relationship between the spectral measurements and material decomposition estimates. The bias and standard deviation of material decomposition estimates were compared for the two methods, …

Energy-Sharing (E,2e) Collisions: Ionization Of The Inert Gases In The Perpendicular Plane, F. K. Miller, H. R. J. Walters, Colm T. Whelan

Physics Faculty Publications

The triple differential cross section for ionization of the inert gases He, Ne, Ar, Kr, and Xe in energy-sharing perpendicular plane geometry is investigated. Encouraging agreement with recent experiments is found using the distorted-wave Born approximation (DWBA). Mechanisms are discussed which explain the He and Ne data but which seem to be masked by the greater distortion effects in the heavier targets. The inclusion of postcollisional interaction is explored using Gamow, N_ee, and Ward-Macek, M_ee, factors. While both help to improve the shape of the cross section for He and Ne at the lower energies, they …

Piecing Elections Together In The 21st Century: Social Media, Outreach Strategies, & Community Engagement, Joshua Acevedo

Open Access Theses & Dissertations

This Thesis analyzes the role of social media usage in campaigns and explores methods for operationalizing this campaign phenomenon. Understanding social media and its connection to politics is challenging, for countless researchers have found it difficult to try to explore a relationship between social media and political campaigns. While social media is relatively new and has been on the rise in recent years, there are challenges associated with measurement and capturing relationships. I will first provide a literature review noting key works on the subject that offer valuable insights on the importance of social media and its influence on the …

Versatility Of N-Peptidyl And N-Glycopeptidyl Nitroindolines For The Formation Of Peptide/Glycopeptide Acids, Amides, And Thioesters, Luis Alfonso Barrera

Open Access Theses & Dissertations

N-acyl-7-nitroindolines are photoreactive compounds that are known to acylate a number of nucleophiles in inert aprotic solvents under neutral conditions when illuminated at 350 nm. We have assembled a MUC1-derived peptide and Tn or STn-containing MUC1 glycopeptides with a C-terminal photoreactive 7-nitroindoline linker attached to Sieber amide resin by solid phase peptide synThesis using the Fmoc strategy. This type of construction allows for the cleavage of fully protected photoreactive peptides/glycopeptides from the resin with dilute trifluoroacetic acid, or for the direct photorelease of protected peptide/glycopeptide derivatives. Here we demonstrate that N-peptidyl and N-glycopeptidyl 7-nitrindolines can be photochemically converted into their …

Current-Induced Depairing In The Bi₂Te₃/Fete Interfacial Superconductor, M. N. Kunchur, C. L. Dean, N. Shayesteh Moghadam, J. M. Knight, Q. L. He, H. Liu, J. Wang, R. Lortz, I. K. Sou, Alex Gurevich

Physics Faculty Publications

We investigated current induced depairing in the Bi₂Te₃/FeTe topological insulator-chalcogenide interface superconductor. The measured depairing current density provides information on the magnetic penetration depth and superfluid density, which in turn shed light on the nature of the normal state that underlies the interfacial superconductivity.

A Comparison Of Self-Acceptance Of Disability Between Thai Buddhists And American Christians, Roy K. Chen, Wilaiporn Kotbungkair, Alicia D. Brown

School of Rehabilitation Services & Counseling Faculty Publications

Having a disability can significantly change a person’s life in many aspects. Research has shown that people with disabilities collectively have diminished access and fewer opportunities to pursue education, find gainful employment, and engage in intimate relationships. Self-acceptance of disability is, therefore, critical to help build resilience, confidence, and psychological well-being in this population. The purpose of the study was to compare the self-acceptance of disability in international settings, specifically in the context of religions. The sample of the study included 98 Thai Buddhists and 95 American Christians with neuromuscular disorders. Constructs used for the study included demographic characteristics, Hope …

The Electoral Costs Of Party Agenda Setting: Why The Hastert Rule Leads To Defeat, Jesse Richman

Political Science & Geography Faculty Publications

This study demonstrates that unconditional blocking of bills opposed by a majority of the majority party--as implied by the party cartel model and advocated by former Speaker Dennis Hastert--can produce conditions in which the majority party loses popular support and loses elections. The theoretical analysis and empirical results imply that the use of negative agenda power to block bills is circumscribed by this risk of electoral defeat. As a result, the opportunity for effective negative agenda control is conditional on majority party issue advantage, party polarization, and the distribution of status quo locations. In particular, majority party roll rates should …
