An Investigation Of The Cognitive And Perceptual Mechanisms Involved In Mania-Proneness, Kimberly Mercer

All Theses and Dissertations (ETDs)

The present research investigates the cognitive and perceptual mechanisms involved in mania-proneness. Building on the work of Depue and colleagues: Depue & Iacono, 1989; Depue & Zald, 1993) and Gray: 1994), which identifies links between the Behavioral Activation System: BAS) and the symptoms observed in mania, this research investigates the hypothesis that people who are prone to mania exhibit cognitive and perceptual biases in information processing when presented with achievement-oriented stimuli both at baseline, and after the receipt of a reward. These hypothesized biases were measured via an affective flanker task, a suboptimal priming task, and a judgment task about …

The Small Animals Of Maasai Settlements: Ethnoarchaeological Investigations Of The Commensalism Model, Lior Weissbrod

All Theses and Dissertations (ETDs)

This research was designed to test Tchernov's model of commensalism and the idea that remains of commensal species that today coexist with humans in settlement environments could be used to detect early sedentism in the archaeological record. The validity of the model has been questioned due to the lack of empirical knowledge on commensalism in a wide range of settlement environments including sedentary and more mobile ones. This study examined the commensalism model by focusing on seasonally occupied settlements of Maasai pastoralists in East Africa. Methods from ecology, ethnography, and archaeology were used to document the impact of Maasai settlements …

A Geometric Approach For Deciphering Protein Structure From Cryo-Em Volumes, Sasakthi Abeysinghe

All Theses and Dissertations (ETDs)

Electron Cryo-Microscopy or cryo-EM is an area that has received much attention in the recent past. Compared to the traditional methods of X-Ray Crystallography and NMR Spectroscopy, cryo-EM can be used to image much larger complexes, in many different conformations, and under a wide range of biochemical conditions. This is because it does not require the complex to be crystallisable. However, cryo-EM reconstructions are limited to intermediate resolutions, with the state-of-the-art being 3.6A, where secondary structure elements can be visually identified but not individual amino acid residues. This lack of atomic level resolution creates new computational challenges for protein structure …

Perception And Nonconceptual Apprehension, Arnon Cahen

All Theses and Dissertations (ETDs)

My dissertation articulates and resolves a problem at the heart of debates about how perception guides our actions and deliberations. The problem arises from the independent plausibility but mutual inconsistency of the following theses: * Some perceptions provide us reasons * Only belief-like states provide us reasons * No perception is belief-like I argue that this problem is deeper than has been acknowledged. Simply rejecting any one thesis leads to serious challenges. Nonetheless, I argue that we can unravel the link between having reasons and having belief-like states in a way that explains the initial plausibility of the first thesis. …

Genetic Influences On Preterm Birth, Jevon Plunkett

All Theses and Dissertations (ETDs)

Preterm birth: PTB) is a leading cause of mortality and disease burden globally; however, determinants of human parturition remain largely uncharacterized, making prediction and prevention of difficult. Genetic studies are one way in which we can attempt to better understand this disorder. We first sought to develop a model for the genetic influences on PTB to facilitate gene discovery. Study of standard measures of familial aggregation, the sibling risk ratio and the sibling-sibling odds ratio, and segregation analyses of gestational age, a quantitative proxy for preterm birth, lend support to a genetic component contributing to birth timing, since preterm deliveries …

Response Mapping In Evaluative Priming, Laura Scherer

All Theses and Dissertations (ETDs)

Recently, Scherer and Lambert: 2009) proposed a new model of priming, which they called the Response Mapping: RM) Model. That model assumes that under some circumstances, priming effects are the result of an unintentional tendency for participants to impose the target categorization task onto the primes: which they are supposed to ignore). In the present dissertation, the RM model is reviewed, and the implications and boundary conditions of the model are explored. In Experiments 1 and 2, it was predicted and found that response mapping processes can result in evaluative conditioning effects. That is, priming tasks do not always simply …

The Effect Of Equal Channel Angular Extrusion (Ecae) And Boron Additions On The Mechanical Properties Of A Biomedical Ti-Nb-Zr-Ta (Tnzt) Alloy, Gian Colombo

All Theses and Dissertations (ETDs)

New metastable-beta type titanium alloys based on the biocompatible elements Ti-Nb-Zr-Ta: TNZT) have been developed to address the shortcomings: e.g. incomplete biocompatibility, high modulus, etc.) of the traditionally used materials in joint replacement prostheses. Equal channel angular extrusion: ECAE) processing has the capability to improve the mechanical properties of these alloys to broaden their potential biomedical applications. The focus of this investigation is to evaluate and optimize the ECAE process to produce maximum property improvement, and explore the effectiveness of boron as a grain refining agent. Deformation mechanisms are identified for various processing conditions, and the strain distribution induced during …

Modeling And Dynamic Resource Allocation For High Definition And Mobile Video Streams, Abdel-Karim Al-Tamimi

All Theses and Dissertations (ETDs)

Video streaming traffic has been surging in the last few years, which has resulted in an increase of its Internet traffic share on a daily basis. The importance of video streaming management has been emphasized with the advent of High Definition: HD) video streaming, as it requires by its nature more network resources. In this dissertation, we provide a better support for managing HD video traffic over both wireless and wired networks through several contributions. We present a simple, general and accurate video source model: Simplified Seasonal ARIMA Model: SAM). SAM is capable of capturing the statistical characteristics of video …

The Relationship Between Hand-Nearness, Emotional Arousal, And Visual Processing, Christopher Davoli

All Theses and Dissertations (ETDs)

When an observer holds his or her hands near an object: hand-nearness), visual processing of that object differs in several ways from visual processing of an object far from the hands. Interestingly, the changes that visual processing undergoes during hand-nearness are the same as those that occur when an observer is emotionally aroused. In the present dissertation, three experiments examined whether hand-nearness and emotional arousal affect visual processing through a shared cognitive mechanism. More specifically, it was proposed that hand-nearness activates the same visual processing mechanism that is engaged during arousal. All experiments included replications of studies that have shown …

Light-Harvesting And The Primary Photochemistry Of Roseiflexus Castenholzii, Aaron Collins

All Theses and Dissertations (ETDs)

Photosynthetic organisms have evolved diverse antennas to harvest light of various qualities and intensities. Anoxygenic phototrophs can have bacteriochlorophyll Q_y antenna absorption bands ranging from about 700-1100 nm. This broad range of usable wavelengths has allowed many organisms to thrive in unique environments. Roseiflexus castenholzii is a niche-adapted, filamentous anoxygenic phototroph: FAP) that lacks chlorosomes, the dominant antenna found in all green bacteria. Light-harvesting is realized only in the membrane with BChl a and a variety of carotenoids. Through biochemical and spectroscopic methods, a model for the size and organization of the photosynthetic antenna is presented. Despite the wide …

The Staggered Chiral Perturbation Theory In The Two-Flavor Case And Su(2) Chiral Analysis Of The Milc Data, Xining Du

All Theses and Dissertations (ETDs)

As a part of the Standard Model: SM), Quantum Chromodynamics: QCD) is a widely accepted theory to describe the physics of quarks and gluons. Formulating QCD on finite discrete lattices in Euclidean space-time not only enables one to study the theory non-perturbatively, but also provides a framework analogous to statistical systems, in which numerical methods can be applied. In this work, we concentrate on one specific fermion formalism, staggered fermions. To interpret the data obtained from numerical simulations with staggered fermions, a particular version of chiral perturbation theory: χPT), rooted staggered χPT: rSχPT), is needed to incorporate the discretization effects, …

Development Of Atomistic Potentials For Silicate Materials And Coarse-Grained Simulation Of Self-Assembly At Surfaces, Brian Barnes

All Theses and Dissertations (ETDs)

This thesis is composed of two parts. The first is a study of evolutionary strategies for parametrization of empirical potentials, and their application in development of a charge-transfer potential for silica. An evolutionary strategy was meta-optimized for use in empirical potential parametrization, and a new charge-transfer empirical model was developed for use with isobaric-isothermal ensemble molecular dynamics simulations. The second is a study of thermodynamics and self-assembly in a particular class of athermal two-dimensional lattice models. The effects of shape on self-assembly and thermodynamics for polyominoes and tetrominoes were examined. Many interesting results were observed, including complex clustering, non-ideal mixing, …

Leveraged Buyouts, Long Term Relationship And Financial Contracting, Lei Gao

All Theses and Dissertations (ETDs)

In the first chapter of my dissertation, I study private equity sponsored leveraged buyouts. In this study, I identify and estimate two components of the created value: benefits of debt and influence of private equity. In the second chapter of my dissertation, I study repeated games with private monitoring in continuous time. I apply stochastic filtering theory to characterize the evolution of players' beliefs, which is difficult to do in discrete time. In the third chapter of my dissertation, I study the connection between financial contracting and staged financing in venture capital.

The Pursuit Of Accreditation In Children's Mental Health Care: Motivations, Experiences, And Perceptions, Madeline Lee

All Theses and Dissertations (ETDs)

Accreditation is a growing, worldwide phenomenon and thousands of mental health organizations spend considerable amounts of money and resources towards achieving and maintaining accreditation. Despite its widespread use, the empirical and theoretical literature on accreditation is sparse. This study is the first step towards examining accreditation's potential as an organizational intervention to improve the quality of mental health services. Using a mixed methods multiple case study design, this exploratory study aimed to 1) understand agencies' motivations to pursue accreditation, 2) explore agencies' experiences with the accreditation process, 3) identify mental health care workers' perceptions of how the accreditation process may …

Bodies Of Parchment: Representing The Passion And Reading Manuscripts In Late Medieval England, Sarah Noonan

All Theses and Dissertations (ETDs)

In a diverse range of late-fourteenth- and fifteenth-century devotional literature, Christ's body is metaphorically related to a book or a document at the moment of his crucifixion. His skin transforms into parchment, whips and scourges become pens, and a steady flow of blood, of ink, covers his body and the written page. And each word written onto his parchment body welcomes sustained study, acting as a potential meditative focal point for the devout reader. Through this metaphor and the accompanying materiality of the texts that include it, medieval authors and audiences could imagine intimately interacting with Christ's body during the …

Reducing False Hearing In The Elderly: Variability Training In Meta-Audition, Chad Rogers

All Theses and Dissertations (ETDs)

A large body of work supports the conclusion that older adults derive more benefit than young adults from the addition of contextual information in speech perception: Hutchinson, 1989; Pichora-Fuller, Schneider, & Daneman, 1995; Pichora-Fuller, 2008). More recent work by Rogers, Jacoby, and Sommers: in prep) showed that when contextual information and sensory information favored competing responses, older adults were more likely to falsely "hear" the word favored by context. The current research describes two experiments that attempt to mitigate this age-related increase on contextual reliance. Experiment 1 assessed whether the effects of context in Rogers, Jacoby, & Sommers: in prep) …

Thomas Hoccleve And The Poetics Of Reading, Elon Lang

All Theses and Dissertations (ETDs)

Thomas Hoccleve, the early fifteenth-century London poet who first promoted the notion that Chaucer was the father of English literature, demonstrates an acute awareness that readers would change the form of his own texts over time. Although many scholars consider Hoccleve's style to be derivative of his English predecessors, I argue that his awareness of readers contributed to an innovative style that casts writing and reading as mutually dependent acts of performance. Thus, in depictions of manuscript production and circulation processes, Hoccleve treats his audiences as his creative collaborators. The rich surviving manuscript history for Hoccleve reveals how his texts …

Exploring Tissue Microstructure In Healthy And Diseased Lung Tissue, Michelle Milne

All Theses and Dissertations (ETDs)

This thesis is divided into two parts. The first part examines diffusion in a number of human lung samples, while the second deals with diffusion in the more simplified environment of a single capillary tube. In the lung study we examine various types of lung samples: healthy and diseased) at a variety of diffusion lengths. Diffusion Magnetic Resonance Imaging: MRI) has been a very useful tool in the study of lungs and lung disease, particularly diffusion MRI using hyperpolarized gases, such as helium or xenon. However, since the polarized gas is difficult to prepare and, once prepared, suffers decay of …

Implicit And Explicit Racial Attitudes: Moderation Of Racial Typicality Evaluations, Elena Stepanova

All Theses and Dissertations (ETDs)

Previous research has shown that racial images representing more typical Afrocentric phenotypic characteristics result in more negative evaluations, whether assessed by explicit or implicit attitudes measures. However, the factors that define and moderate the perception of racial typicality have not been sufficiently explored. The current research investigated additive and interactive influences of skin tone and facial physiognomy on racial typicality evaluations, as well as the degree to which those effects were moderated by explicit and implicit racial attitudes, ethnicity of participants, and availability of cognitive resources. Using a 6-point scale ranging from very African American to very Caucasian, participants: N …

Orientation-Specific Control Of Attention, Feng Du

All Theses and Dissertations (ETDs)

Previous studies have shown that an irrelevant distractor matched to a sought-for color captures attention involuntarily, thus violating either temporal or spatial control of attention. However, whether an irrelevant distractor that matches a sought-for orientation can capture attention is still unknown. A task of rapid serial visual presentation: RSVP) was developed to examine whether an irrelevant distractor oriented in the same way as the target can capture attention. Participants were presented with a sequence of letters at fixation and were required to search for the target letter with a specific orientation. In all five experiments, six peripheral bars flanked the …

Frustrated Magnetism In Distorted Triangular Lattice Materials; & Extraordinary Electroconductance In Iii-V Metal Semiconductor Hybrid Structures, Jian Wu

All Theses and Dissertations (ETDs)

PART I: We have synthesized a series of spin S = 1/2 distorted triangular lattice materials Cu_2(1-x)Zn_2x(OH)₃NO₃and their long chain alkyl carboxylic group intercalated derivatives, Cu_2(1-x)Zn_2x(OH)₃(C₇H₁₅COO).mH₂O). Their structural properties, magnetic properties and specific heat have been carefully studied in this thesis. We found that antiferromagnetic-type long-range order develops in all the nitrate group compounds below the Neel temperatures T_N, which decreases with increasing Zn content. For the organic long chain intercalated samples, the temperature dependence of magnetic susceptibility …

Teaching News Literacy In The Age Of New Media: Why Secondary School Students Should Be Taught To Judge The Credibility Of The News They Consume, Elia Powers

All Theses and Dissertations (ETDs)

This paper involves two of the oldest institutions in America -- schools and the press -- and the preparation of informed citizens in the age of new media. I examine the manner and ways in which news literacy, the use of critical thinking skills to judge the reliability of news reports and news sources, is taught to secondary school students in the United States. It is axiomatic that a vigorous and independent press is critical to our democracy. Yet news literacy has not historically been included in the public school curriculum and continues to be widely absent, despite states vowing …

An Environment For Stroke Therapy Game Authoring, Simon Tam

All Theses and Dissertations (ETDs)

Stroke is the leading cause of disability in the industrialized world. The disabilities caused by stroke can significantly impact the quality of daily life for stroke survivors. Studies show that a high number of daily body movement repetitions can help recover lost motor functionality. However, many stroke patients do not perform the home exercises needed to reach this high number of repetitions. Games for rehabilitation have been shown to provide motivation to perform home exercises. However, because stroke can leave survivors with different levels of disability, custom games are required. Creating custom games, though, is time consuming and requires advanced …

A Study Of The Adjunct Faculty Experiences In The Creation Of A Teacher Work Sample, Anna L. Conway

Dissertations and Theses @ UNI

Part-time and adjunct faculty members have been present in institutions of higher learning since the founding of this country. These groups of faculty provide a variety of unique professional experiences to their students; they offer financial savings and scheduling flexibility for their colleges and on many levels, adjuncts offer a range of other valuable contributions to their institutions. The purpose of this study was to examine the experiences that community college adjunct faculty had with college teaching and implementation of the Teacher Work Sample. Another objective was to see how the completion of Teacher Work Sample contributed to the adjuncts' …

The Wisdom Of Crowds? Groupthink And Nonprofit Governance, Melanie B. Leslie

Articles

Scandals involving nonprofit boards and conflicts of interest continue to receive considerable public attention. Earlier this year, for example, musician Wyclef Jean's Yele Haiti charity became the target of intense criticism after the charity disclosed that it had regularly transacted business with Jean and entities controlled by Jean and other directors. Although scandals caused by self-dealing undermine public confidence in the charitable sector, they continue to erupt. Why do charitable boards sanction transactions with insiders?

This Article argues that much of the blame lies with the law itself. Because fiduciary duty law is currently structured as a set of fuzzy …

An Airloads Theory For Morphing Airfoils In Dynamic Stall With Experimental Correlation, Loren Ahaus

All Theses and Dissertations (ETDs)

Helicopter rotor blades frequently encounter dynamic stall during normal flight conditions, limiting the applicability of classical thin-airfoil theory at large angles of attack. Also, it is evident that because of the largely different conditions on the advancing and retreating sides of the rotor, future rotorcraft may incorporate dynamically morphing airfoils: trailing-edge flaps, dynamic camber, dynamic droop, etc.). Reduced-order aerodynamic models are needed for preliminary design and flight simulation. A unified model for predicting the airloads on a morphing airfoil in dynamic stall is presented, consisting of three components. First, a linear airloads theory allows for arbitrary airfoil deformations consistent with …

Envisioning Morality In Times Of Dynastic Change, Huan Jin

All Theses and Dissertations (ETDs)

The emphasis placed on morality became increasingly remarkable during late imperial China, especially at the junctures of dynastic change. This thesis explores the problem of the construction of morality, and I focus on two plays in which the idea of morality is presented in complicated ways: the late Yuan play Pipa ji τÉ╡τÉ╢Φ«░: The Lute) which primarily circulated during Ming and Qing Dynasties, and the early Qing play Taohua shan µíâΦè▒µëç: The Peach Blossom Fan) which deals with the late Ming period. In this thesis, I primarily treat these two plays as texts, and I try to answer how ideas …

Bayesian Multilevel Analysis Of Binary Time-Series Cross-Sectional Data In Political Economy, Xun Pang

All Theses and Dissertations (ETDs)

In this dissertation project, I propose a Bayesian generalized linear multilevel model with pth order autoregressive errors: GLMM-AR(p)) for modeling inter-temporal dependence, con-temporary correlation, and heterogeneity of unbalanced binary Time- Series Cross-Sectional data. The model includes two unnested sources of clustering in the unit- and time-dimensions for analyzing heterogeneities and contemporal corre- lation which are salient in the era of globalization. Group-level variations are further explained with unit- and time-specific characteristics. For handling dynamics in pol- itics and political economy, I apply the autoregressive error specification to analyze serial correlation which may not be fully captured by the selected covariates. …
