Promises And Expectations, Florian Ederer, Alexander Stremitzer

Cowles Foundation Discussion Papers

We investigate why people keep their promises in the absence of external enforcement mechanisms and reputational effects. In a controlled laboratory experiment we show that exogenous variation of second-order expectations (promisors’ expectations about promisees’ expectations that the promise will be kept) leads to a significant change in promisor behavior. We provide clean evidence that a promisor’s aversion to disappointing a promisee’s expectation leads her to keep her promise. We propose a simple theory of lexicographic promise keeping that is supported by our results and nests the findings of previous contributions as special cases.

The Pursuit Of High Academic Growth For Gifted Middle Level Learners, Linda Elizabeth Pfeiffer

Dissertations

The purpose of this study was to build an understanding of what should be present in schools to meet the academic growth needs of gifted middle-level learners. In times of financial difficulty it is important that educators find ways to meet the needs of all students while afforded little resources to do so. While understandable that finances be provided for struggling students, it should not be at the expense of those who come to school with content mastery already achieved but still eager to learn new material. The results of this study indicate that meeting the academic, high growth needs …

Synthesis Of Resveratrol Ester Derivatives, Daniel Ressler

Electronic Theses and Dissertations

The goal of this research project was to synthesize derivatives of transresveratrol. In order for resveratrol to be activated and used by the body it needs to bind to Human Serum Albumin (HSA), a protein in blood plasma. The derivatives were synthesized to improve the ability of resveratrol to enter cells as well as improve their ability to bind to HSA. The three derivatives that were synthesized have converted one of the hydroxyl groups on resveratrol to an ether with a methylene chain terminated by a carboxylic acid. By varying the lengths of the methylene chain we varied the water …

Actively Caring About The Actively Caring Survey: Evaluating The Reliability And Validity Of A Measure Of Dispositional Altruism, Philip Randall

Electronic Theses and Dissertations

Geller’s Actively Caring Survey (ACS) was theorized to measure person states deemed necessary to “Actively Care” or act altruistically toward others. Empirical research of the ACS has been limited, and this researcher sought to evaluate its reliability, validity, and factorial consistency. Undergraduate students (n = 1,095) completed the measure online. Hypotheses were partially supported. Unrotated primary component analysis found the ACS to be a unitary measure with 73.3% of the items loading onto the first factor. The ACS showed excellent internal consistency. Convergent and divergent validity with existing measures (i.e., the Big 5 Personality, Marlowe-Crowne Social Desirability, Cognitive Failures …

Physical Security Assessment Of A Regional University Computer Network, Nathan H. Timbs

Electronic Theses and Dissertations

Assessing a network's physical security is an essential step in securing its data. This document describes the design, implementation, and validation of PSATool, a prototype application for assessing the physical security of a network's intermediate distribution frames, or IDFs (a.k.a. "wiring closets"). PSATool was created to address a lack of tools for IDF assessment. It implements a checklist-based protocol for assessing compliance with 52 security requirements compiled from federal and international standards. This checklist can be extended according to organizational needs.

PSATool was validated by using it to assess physical security at 135 IDFs at East Tennessee State University. …

Instructor And Student Perceptions Of Online Courses: Implications Of Positioning Theory, Miriam S. Phillips

Electronic Theses and Dissertations

The increase in online course delivery in higher education has implications for students and instructors. In fall 2002, 1.6 million students took at least one online course and this number increased by the fall of 2012 to 6.7 million. The increase in the rate of enrollment in online courses in higher education provides an opportunity to examine the strategies and technologies used in course design and delivery and student engagement in the online culture. Two of the key factors in creating student engagement are the instructor's interaction with students and the course design and delivery itself. An examination of students’ …

Effect Of The Insecticide Lambda-Cyhalothrin On Rice Spider Populations In Southern Brazil, Everton N. L. Rodrigues, Milton De S. Mendonça Jr., Leila L. Fritz, Elvis A. Heinrichs, Lídia Fiuza

Department of Entomology: Faculty Publications

The adverse effect that insecticides have on spider populations is of major concern since these predators are a component in the biological control of rice insect pest populations. This study was designed to determine the effect of the pyrethroid insecticide Lambda-cyhalothrin on spider populations in rice fields. Treatments consisted of plots treated once with the insecticide and untreated plots (control). Spiders were sampled four times per crop year over a two-year period in each of three sites in the state of Rio Grande dol Sul, Brazil. Treatments were replicated four times. Sweep net sampling was conducted to sample the araneofauna. …

Remote Estimation Of Nitrogen And Chlorophyll Contents In Maize At Leaf And Canopy Levels, Michael Schlemmer, Anatoly A. Gitelson, James S. Schepers, Richard B. Ferguson, Y. Peng, J. Shanahan, Donald Rundquist

Department of Agronomy and Horticulture: Faculty Publications

Leaf and canopy nitrogen (N) status relates strongly to leaf and canopy chlorophyll (Chl) content. Remote sensing is a tool that has the potential to assess N content at leaf, plant, field, regional and global scales. In this study, remote sensing techniques were applied to estimate N and Chl contents of irrigated maize (Zea mays L.) fertilized at five N rates. Leaf N and Chl contents were determined using the red-edge chlorophyll index with R2 of 0.74 and 0.94, respectively. Results showed that at the canopy level, Chl and N contents can be accurately retrieved using green and red-edge Chl …

Optimal Copper Supply Is Required For Normal Plant Iron Deficiency Responses, Brian M. Waters, Laura C. Armbrust

Department of Agronomy and Horticulture: Faculty Publications

Iron (Fe) and copper (Cu) homeostasis are tightly linked across biology. Understanding crosstalk between Fe and Cu nutrition could lead to strategies for improved growth on soils with low or excess metals, with implications for agriculture and phytoremediation. Here, we show that Cu and Fe nutrition interact to increase or decrease Fe and/or Cu accumulation in leaves and Fe uptake processes. Leaf Cu concentration increased under low Fe supply, while high Cu lowered leaf Fe concentration. Ferric reductase activity, an indicator of Fe demand, was inhibited at insufficient or high Cu supply. Surprisingly, plants grown without Fe were more susceptible …

Repeated Elevational Transitions In Hemoglobin Function During The Evolution Of Andean Hummingbirds, Joana Projecto-Garcia, Chandrasekhar Natarajan, Hideaki Moriyama, Roy E. Weber, Angela Fago, Zachary A. Cheviron, Robert Dudley, Jimmy A. Mcguire, Christopher C. Witt, Jay F. Storz

School of Biological Sciences: Faculty Publications

Animals that sustain high levels of aerobic activity under hypoxic conditions (e.g., birds that fly at high altitude) face the physiological challenge of jointly optimizing blood-O₂ affinity for O₂ loading in the pulmonary circulation and O₂ unloading in the systemic circulation. At high altitude, this challenge is especially acute for small endotherms like hummingbirds that have exceedingly high mass-specific metabolic rates. Here we report an experimental analysis of hemoglobin (Hb) function in South American hummingbirds that revealed a positive correlation between Hb-O₂ affinity and native elevation. Protein engineering experiments and ancestral- state reconstructions revealed that this …

Reflections On The Metamorphosis At Robben Island: The Role Of Institutional Work And Positive Psychological Capital, Wayne F. Cascio, Fred Luthans

Department of Management: Faculty Publications

Nelson Mandela and other political prisoners from South Africa were imprisoned on notorious Robben Island from the mid-1960s until the end of the apartheid regime in 1991. The stark conditions and abusive treatment of these prisoners has been widely publicized. However, upon reflection and in retrospect, over the years, a type of metamorphosis occurred. Primarily drawing from firsthand accounts of the former prisoners and guards, it seems that Robben Island morphed from the traditional oppressive prison paradigm to one where the positively oriented prisoners disrupted the institution with a resulting climate of learning and transformation that eventually led to freedom …

Tiers 2 & 3 Intervention: Behavior Monitoring, Emily Moss, Ann O'Connor, Reece L. Peterson

Department of Special Education and Communication Disorders: Faculty Publications

Conclusion

Individual student behavior monitoring is useful at all grade levels as part of a behavior changes strategy, starting early in a child’s education and continuing throughout high school. Through monitoring and teaching students to set behavior goals, schools can expect improved behavior, and behavior monitoring is an essential element of efforts to change individual student behavior. Its use has strong research support when part of a more comprehensive plan to monitor and intervene to change individual behaviors.

School personnel can also use long term behavior monitoring as a way to identify student who are at risk for dropping out …

Turbulent Kinetic Energy And Coherent Structures In A Tidal River, Stefan A. Talke, Alexander R. Horner-Devine, C. Chris Chickadel, Andrew T. Jessup

Civil and Environmental Engineering Faculty Publications and Presentations

We investigate the relationship between turbulence statistics and coherent structures (CS) in an unstratified reach of the Snohomish River estuary using in situ velocity measurements and surface infrared (IR) imaging. Sequential IR images are used to estimate surface flow characteristics via a particle-image-velocimetry (PIV) technique, and are conditionally sampled to delineate the surface statistics of bottom-generated CS, or boils. In the water column, we find that turbulent kinetic energy (TKE) production exceeds dissipation near the bed but is less than dissipation in the midwater column and that TKE flux divergence closes a significant portion of the measured imbalance. The surface …

The Hearts Of Ovid's Heroines In Trojumanna Saga, Luke J. Chambers

Masters Theses

In western civilization no story has been retold more times than the Trojan War. Homer's works were known only by repute in western Europe after the fall of Rome. As such, the Middle Ages saw the blossoming of a new Troy tradition based on Dares Phrygius's De Excidio Troiae Historia (The History of the Destruction of Troy). Most countries of medieval Europe used this laconic work to retell the Troy story in each country's particular idiom.

The settlers of Iceland developed a sophisticated literary culture in the thirteenth century. No other people wrote narrative prose works on such a …

Origin Of High Levels Of Ammonium In Groundwater, Ottawa County, Michigan, Derrick Lingle

Masters Theses

Groundwater from wells located in and around Hemlock Crossing Park in Ottawa County, Michigan has elevated levels of ammonium. High ammonium concentrations in potable water wells are a common indicator of anthropogenic impact, such as landfill leachate or agricultural activity. Ammonium can also occur in groundwater through the decay of natural organic material. Along with the retrieval of a complete glacial sediment core via rotasonic drilling, numerous chemical and isotopic parameters were used to determine the source of ammonium in the impacted aquifer.

Buried organic material, deposited during the Athens subepisode interglacial period, is in contact with groundwater containing elevated …

Sensitivity And Species Specificity Of Bisulfite Modification And Pyrosequencing Technology Used To Identify Tissue-Specific Dna Methylation Patterns In Common Biofluids Foudn In Crime Scenes, Sitara Christian Shirwani

Master's Theses

In order to convict the guilty or exonerate the innocent in criminal cases, it is crucial to reconstruct the crime scene and/or determine the nature of the crime. Identifying the different biofluids found at a crime scene can help shed light on these aspects of forensic casework. Recently, DNA methylation has been used as a means of identifying biological materials, as opposed to conventional protein/enzyme based methods. DNA methylation is the addition of a methyl group to the 5' carbon on a cytosine base (C), which is directly followed by a guanine base (G) and are called CpG sites. The …

Assessing Respiration Rates And Nutrient Dynamics Of Aritifical Reef Biofilms And Bacterioplankton In The Mississippi Sound, Lynn Elizabeth Wilking

Master's Theses

Artificial reefs are primarily used to provide a suitable habitat for target fish populations, but the structures can also improve water quality and benefit non-target organisms. Laboratory incubation experiments were conducted in the presence of biofilm on rubble and in its absence to examine bacterial growth, community respiration, and nutrient dynamics at four artificial reef habitats in the Mississippi Sound. Biofilm samples were also collected from settlement plates deployed at each site and were analyzed for 813C and 81sN stable isotope content. Respiration rates were always higher in the presence of biofilm but bacterial abundance often declined over time, and …

Remote/Autonomous Sentry Gun Platform, Angelo Gagliardi, Dante Gagliardi

Electrical Engineering

This senior project involves the complete system design and construction of a "Nerf" sentry gun to replace an armed guard. We aimed to develop a compact and highly mobile defense system that allows operational flexibility. The sentry gun can autonomously track and shoot at moving targets, while also allowing a user to remotely access and control the gun via computer. The mobility, hardiness, and functionality of this system allows a reliable replacement for human beings in harsh and hostile environments; ultimately sparing a life.

Scanned Ion Beam Therapy For Thoracic Tumors, John Gordon Eley

Dissertations and Theses (Open Access)

Although frequently cured of Hodgkin lymphoma, adolescents and young adults can develop radiation induced second cancers. These patients could potentially benefit from scanned ion radiotherapy yet likely would require motion mitigation strategies. In theory, four-dimensional (4D) optimization of ion beam fields for individual motion states of respiration can enable superior sparing of healthy tissue near moving targets, compared to other motion mitigation strategies. Furthermore, carbon-ion therapy can sometimes provide greater relative biological effectiveness (RBE) for cell sterilization in a target but nearly equivalent RBE in tissue upstream of the target, compared to proton therapy. Thus, we expected that for some …
