Biogeography-Based Optimization In Noisy Environments, Haiping Ma, Minrui Fei, Daniel J. Simon, Zixiang Chen

Electrical and Computer Engineering Faculty Publications

Biogeography-based optimization (BBO) is a new evolutionary optimization algorithm that is based on the science of biogeography. In this paper, BBO is applied to the optimization of problems in which the fitness function is corrupted by random noise. Noise interferes with the BBO immigration rate and emigration rate, and adversely affects optimization performance. We analyse the effect of noise on BBO using a Markov model. We also incorporate re-sampling in BBO, which samples the fitness of each candidate solution several times and calculates the average to alleviate the effects of noise. BBO performance on noisy benchmark functions is compared with …

Foresight Bias In Patent Law, Sean B. Seymore

Vanderbilt Law School Faculty Publications

Much of patent reform has focused on efforts to make it harder to obtain and enforce low-quality patents. The most straightforward way to achieve this goal is to raise the substantive standards of patentability. What is often ignored in discussions about raising patentability standards is that high-quality inventions can slip through the cracks. What is more troubling is that sometimes this happens because of bias. This Article draws attention to foresight bias, which occurs when a decision-maker lets over-pessimism and an oversimplified view of the future influence the patentability determination. Foresight bias leads to a patent denial regardless of the …

An Exposure-Effect Approach For Evaluating Ecosystem-Wide Risks From Human Activities, Am Knights, Gj Piet, Rh Jongbloed, Et Al

School of Biological and Marine Sciences

Ecosystem-based management (EBM) is promoted as the solution for sustainable use. An ecosystem-wide assessment methodology is therefore required. In this paper, we present an approach to assess the risk to ecosystem components from human activities common to marine and coastal ecosystems. We build on: (i) a linkage framework that describes how human activities can impact the ecosystem through pressures, and (ii) a qualitative expert judgement assessment of impact chains describing the exposure and sensitivity of ecological components to those activities. Using case study examples applied at European regional sea scale, we evaluate the risk of an adverse ecological impact from …

Disorders Of Sex Development: Lessons To Be Learned From Studies Of Spina Bifida And Craniofacial Conditions, Grayson N. Holmbeck, C L. Aspinall

Psychology: Faculty Publications and Other Works

The purpose of this review is to discuss research methods and clinical management strategies employed with other conditions (i. e., spina bifida and craniofacial conditions) and how these methods and strategies could be applied to youth with disorders of sex development (DSD). The review focuses specifically on the potential overlap between DSD and these other conditions across the following 3 areas: (1) developmentally- oriented theories that underlie the research base for chronic physical conditions; (2) research designs and methodological features that have proved fruitful in these areas; and (3) the potential applicability to DSD of clinical management practices for youth …

Exploring Water Indices And Associated Parameters: A Case Study Approach, Thushara Gunda, Laura Benneyworth, Emily Burchfield

Environment and Society Faculty Publications

In the past 20 years, over 50 water indices have been developed to characterize human-water systems within the frameworks of water scarcity, water poverty, water vulnerability, and water security. This study compares existing water indices in Bangladesh and Sri Lanka to better understand which parameters (or lack thereof) contribute to the usefulness of water indices. Drawing on knowledge about human-water interactions in Bangladesh and Sri Lanka, this exploration of indices at the parameter level highlights missing parameters, inadequate consideration of complex relationships between parameters, and inconsistencies in index nomenclature and units. This study reveals both the benefits and shortcomings of …

Intrinsically Disordered C-Terminal Tails Of E. Coli Single-Stranded Dna Binding Protein Regulate Cooperative Binding To Single-Stranded Dna, Alexander G. Kozlov, Elizabeth A. Weiland, Anuradha Mittal, Vince Waldman, Edwin Antony, Nicole Fazio, Rohit V. Pappu, Timothy M. Lohman

Biological Sciences Faculty Research and Publications

The homotetrameric Escherichia coli single-stranded DNA binding protein (SSB) plays a central role in DNA replication, repair and recombination. E. coli SSB can bind to long single-stranded DNA (ssDNA) in multiple binding modes using all four subunits [(SSB)₆₅ mode] or only two subunits [(SSB)₃₅ binding mode], with the binding mode preference regulated by salt concentration and SSB binding density. These binding modes display very different ssDNA binding properties with the (SSB)₃₅ mode displaying highly cooperative binding to ssDNA. SSB tetramers also bind an array of partner proteins, recruiting them to their sites of action. This is …

Unique Competitive Effects Of Lianas And Trees In A Tropical Forest Understory, Alexandra Wright, Michael F. Tobin, Scott A. Mangan, Stefan A. Schnitzer

Biological Sciences Faculty Research and Publications

Lianas are an important component of tropical forests, contributing up to 25 % of the woody stems and 35 % of woody species diversity. Lianas invest less in structural support but more in leaves compared to trees of similar biomass. These physiological and morphological differences suggest that lianas may interact with neighboring plants in ways that are different from similarly sized trees. However, the vast majority of past liana competition studies have failed to identify the unique competitive effects of lianas by controlling for the amount of biomass removed. We assessed liana competition in the forest understory over the course …

Isolation Of Diverse Members Of The Aquificales From Geothermal Springs In Tengchong, China, Brian P. Hedlund, Anna-Louise Reysenbach, Liuquin Huang, John C. Ong, Zizhang Liu, Jeremy A. Dodsworth, Reham Ahmed, Amanda J. Williams, Brandon R. Briggs, Yitai Liu, Weiguo Hou, Hailiang Dong

Biology Faculty Publications and Presentations

The order Aquificales (phylum Aquificae) consists of thermophilic and hyperthermophilic bacteria that are prominent in many geothermal systems, including those in Tengchong, Yunnan Province, China. However, Aquificales have not previously been isolated from Tengchong. We isolated five strains of Aquificales from diverse springs (temperature 45.2–83.3°C and pH 2.6–9.1) in the Rehai Geothermal Field from sites in which Aquificales were abundant. Phylogenetic analysis showed that four of the strains belong to the genera Hydrogenobacter, Hydrogenobaculum, andSulfurihydrogenibium, including strains distant enough to likely justify new species ofHydrogenobacter and Hydrogenobaculum. The additional strain may represent a …

"'The Law’S The Law, Right?' Sexual Minority Mothers Navigating Legal Inequities And Inconsistencies.”, Emily Kazyak

Department of Sociology: Faculty Publications

LGB parents face a number of legal inequities and confront a legal landscape that not only varies drastically by state but also quickly changes. Research has shown that some LGB parents and prospective parents have inaccurate knowledge about the laws relating to parenting. Drawing on data from 21 interviews, I ask how sexual minority mothers gain knowledge about the law. I found that people were very aware of the legal inequities they face and sought to become knowledgeable about the law before they had children. Sexual minority mothers reported using four primary methods to learn about the law: doing independent …

Using The New Dual-Polarimetric Capability Of Wsr-88d To Eliminate Anomalous Propagation And Wind Turbine Effects In Radar-Rainfall, Bong Chul Seo, Witold F. Krajewski, Kumar Vijay Mishra

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

This study addresses the effect that the interaction between anomalous radar beam propagation (AP) and wind turbines that are located far from the radar has on radar-rainfall estimates. The interference of wind turbines in radar observations may lead to significant errors in rainfall estimates since wind turbines are often clustered to form wind farms. In this study, we propose a novel approach - based on the polarimetric capability recently added to the WSR-88D NEXRAD radars - that identifies and eliminates wind turbine clutter along with common ground clutter AP effects. Our primary objective is to devise a physically meaningful and …

Becoming And Being: Atheism As A Social Experience In Egypt, Wael Ossama Al-Soukkary

Theses and Dissertations

This project involves discovering how some Egyptian atheists develop and manage their identity. The goal of the research is to demonstrate the different variables that influence the transformation to atheism. This research also seeks to explore the different ways Egyptian atheists deal with the stigma associated with their identity once they self-identity as atheists. Upon examination and analysis of my interlocutors' account it became clear that atheism is not only organic to the Egyptian culture but also a significantly fluid identity.

Explorations Of Perceived Product Efficacy, Veronika Ilyuk

Dissertations, Theses, and Capstone Projects

Prior research has largely treated perceived product efficacy as a one-dimensional construct. This research uniquely demonstrates that perceived product efficacy is comprised of several dimensions and focuses on one previously unexplored dimension that has significant implications for consumption frequency: perceived duration of product efficacy. The current research shows that consumers make biased duration judgments of product efficacy: consumers make shorter (vs. longer) duration judgments when they perceive a concurrent task to be relatively difficult (vs. easy). The effect of perceived task difficulty on duration judgments of product efficacy is (1) established with energy-enhancing products and medication, (2) shown to be …

Highly-Selective Chemiresistive Sensing And Analysis Of Vapors Using Functionalized Nanotubes, Deon Hines

Dissertations, Theses, and Capstone Projects

Specifically, the project involves the development of a diversified array of nanostructured gas-sensors comprised of selectively, novel surface-functionalized carbon nanotubes (for analyte selectivity by virtue of functionality). Harnessing carbon nanotubes with various electron withdrawing and donating groups help in determining their affinity toward certain prognostic gaseous markers thus increasing specificity of such created sensors. We have devised synthetic routes that have led to the facile production of covalently polyfunctionalized nanotubes in high yield. Seven carbon nanotube analogues were systematically considered and then chemically synthesized, from pristine single-walled nanotubes (SWNT's), for use as the main component of sensory units that was …

Performing Blackness In A Mulatto Society: Negotiating Racial Identity Through Music In The Dominican Republic, Angelina Maria Tallaj-García

Dissertations, Theses, and Capstone Projects

My dissertation analyzes Dominican racial and ethnic identity through an examination of music and music cultures. Previous studies of Dominican identity have focused primarily on the racialized invention of the Dominican nation as white, or non-black, often centering on the building of Dominican identity in (sometimes violent) opposition to the Haitian nation and to Haitian racial identity. I argue that although Dominicans have not developed an explicit verbal discourse of black affirmation, blackness (albeit a contextually contingent articulation) is embedded in popular conceptions of dominicanidad ("Dominicanness") and is enacted through music. My dissertation explores ways in which popular notions of …

Attention In Hiv, Kathleen Marie Van Dyk

Dissertations, Theses, and Capstone Projects

In contrast to the striking benefit of advances in antiretroviral therapy on longevity and health in the HIV+ population, mild cognitive disorders persist (Heaton, Clifford et al., 2010). Additional factors that may be related to cognitive decline and warrant consideration in this population are aging and physical health status. Among cognitive domains affected, attention and processing speed have emerged as particularly vulnerable to the effects of HIV. There are also age effects observed in these domains, and we proposed that reduced physical health can also impact cognition in these areas, comparably to pain. Sensitive measures of attention that vary attentional …

Eight students in grades 4-6 at Riverton Elementary School were selected for the study. The name Riverton Elementary School is a pseudonym. Pseudonyms were used in this study for the name and location of the school and also used for the names of students, teachers, and parents. This study asked what is it about highly achieving students' culture which makes them achieve at high levels despite the lack of parental involvement? What habits do these highly achieving students possess? …

Effects Of Colony Creation Method And Beekeeper Education On Honeybee (Apis Mellifera) Mortality, J Reed Findlay, Benjamin Eborn, Wayne Jones

Journal of Extension

The two-part study reported here analyzed the effects of beekeeper education and colony creation methods on colony mortality. The first study examined the difference in hive mortality between hives managed by beekeepers who had received formal training in beekeeping with beekeepers who had not. The second study examined the effect on hive mortality between hives that were initiated as nucleus or package colonies. Colonies created from package bees were more likely to survive for 1 year than nucleus colonies. Colonies managed by beekeepers who had received formal education also exhibited better survival rates than those managed by non-educated beekeepers.

Cell Viability Assessment Using The Alamar Blue Assay: A Comparison Of 2d And 3d Cell Culture Models, Franck Bonnier, Mark Keating, Tomasz P. Wrobel, Katarsyna Majzner, Malgorzata Baranska, Amaya Garcia, Alfonso Blanco, Hugh Byrne

Articles

Comparisons of 2D and 3D cell culture models in literature have indicated differences in cellular morphology and metabolism, commonly attributed the better representation of in vivo conditions of the latter cell culture environment. Thus, interest in the use of 3D collagen gels for in vitro analysis has been growing. Although comparative studies to date have indicated an enhanced resistance of cells on collagen matrices against different toxicants, in the present study it is demonstrated that non-adapted protocols can lead to misinterpretation of results obtained from classical colorometric dye-based cytotoxic assays. Using the well established Alamar Blue assay, the …

Sieve Instrumental Variable Quantile Regression Estimation Of Functional Coefficient Models, Liangjun Su, Tadao Hoshina

Research Collection School Of Economics

In this paper, we consider sieve instrumental variable quantile regression (IVQR) estimation of functional coefficient models where the coefficients of endogenous regressors are unknown functions of some exogenous covariates. We approximate the unknown functional coefficients by some basis functions and estimate them by the IVQR technique. We establish the uniform consistency and asymptotic normality of the estimators of the functional coefficients. Based on the sieve estimates, we propose a nonparametric specification test for the constancy of the functional coefficients, study its asymptotic properties under the null hypothesis, a sequence of local alternatives and global alternatives, and propose a wild-bootstrap procedure …

Background : Intracranial atherosclerotic disease (ICAD) is the most frequent subtype of ischemic stroke globally. It is important to describe the determinants of early ICAD as a strategy to prevent strokes from clinically evident and progressive ICAD. Our objective is to report the determinants of asymptomatic ICAD by linking the presence or absence of ICAD on magnetic resonance angiogram (MRA) with detailed risk assessment in asymptomatic adults.

Methods : This is an observational cross-sectional analytical study. We plan to recruit 200 adult participants from the radiology departments of two tertiary care centers of Karachi, Pakistan. The participants will first be …

Copper-Induced Intra-Specific Oxidative Damage And Antioxidant Responses In Strains Of The Brown Alga Ectocarpus Siliculosus With Different Pollution Histories, Ca Sáez, F Roncarati, A Moenne, Aj Moody, Mt Brown

School of Biological and Marine Sciences

Inter- and intra-specific variation in metal resistance has been observed in the ecologically and economically important marine brown macroalgae (Phaeophyceae), but the mechanisms of cellular tolerance are not well elucidated. To investigate inter-population responses of brown seaweeds to copper (Cu) pollution, the extent of oxidative damage and antioxidant responses were compared in three strains of the filamentous brown seaweed Ectocarpus siliculosus, the model organism for the algal class Phaeophyceae that diverged from other major eukaryotic groups over a billion year ago. Strains isolated from locations with different pollution histories (i.e. LIA, from a pristine site in Scotland; REP and Es524 …

Elucidation Of The Cellular And Molecular Mechanisms Of Missense Mutations Associated With Familial Exudative Vitreoretinopathy And Congenital Myasthenic Syndrome, Reham Mahmoud Mohammed Milhem

Dissertations

The endoplasmic reticulum (ER), within eukaryotic cells, is a hub for protein folding and assembly. Misfolded proteins and unassembled subunits of protein complexes are retained in the ER and degraded by a process termed endoplasmic reticulum associated degradation (ERAD). Frizzled class receptor 4 (FZD4) and muscle, skeletal, receptor tyrosine kinase (MuSK) are Wnt receptors. These proteins contain the frizzled cysteine-rich domain (Fz-CRD) required for dimerization in the ER. Mutations in FZD4 and MuSK genes are known to cause familial exudative vitreoretinopathy (FEVR, an autosomal dominant disease) and congenital myasthenic syndrome (CMS, an autosomal recessive disease), respectively. It was hypothesized that …

Estimating The Production Function For Human Capital: Results From A Randomized Control Trial In Colombia, Orazio P. Attanasio, Sarah Cattan, Emla Fitzsimons, Costas Meghir, Marta Rubio-Codina

Cowles Foundation Discussion Papers

We examine the channels through which a randomized early childhood intervention in Colombia led to significant gains in cognitive and socio-emotional skills among a sample of disadvantaged children aged 12 to 24 months at baseline. We estimate the determinants of parents’ material and time investments in these children and evaluate the impact of the treatment on such investments. We then estimate the production functions for cognitive and socio-emotional skills. The effects of the program can be explained by increases in parental investments, emphasizing the importance of parenting interventions at an early age.

"I Shall Not Fear:" Secure Attachment To G-D As A Buffer Against Anxiety, Peryl Agishtein

Dissertations, Theses, and Capstone Projects

Religion has a long and mixed history in the field of psychology. Historically, some leading figures in the field viewed religion as a source of neuroses and poor mental health; others saw a more positive spiritual resource. Recently, empirical data on religion and mental health has proliferated. There is now consensus that religion is associated with lower depression. However, the link between religion and anxiety is less clear-cut. This paper proposes that a) religion can have exacerbating or alleviating effects on anxiety depending on which aspect of religion is being studied and b) the primary religious variable that affects anxiety …

Population Genomic Inference Of Ecology, Conservation, Evolution, And Demographic History Of Atlantic Seahorses And Pipefishes (Syngnathidae), Joel Thomas Boehm

Dissertations, Theses, and Capstone Projects

In the Atlantic Ocean powerful directional ocean currents can play a significant role in the formation and persistence of marine species. Syngnathidae fishes have a sparse fossil record, high morphological plasticity, and many of these species are difficult to observe in the wild, therefore they frequently lack life history information and the status of regional lineages and species designations are often obscure. In this dissertation I explore the ecology, evolution, and conservation of primarily Atlantic seahorses (Hippocampus) and pipefish (Syngnathus) in four core chapters, using differing genetic datasets ranging from mitochondrial DNA to genome-wide RAD sequences. Most Synganthids have the …

"Beyond Chingones And Chingados: Performing Masculinities In Contemporary Mexican Theatre", Zaida Godoy Navarro

Dissertations, Theses, and Capstone Projects

The present investigation focuses on how masculinities are conformed and represented in the plays of two generations of Mexican playwrights, the New Dramatists of Mexico and the younger Sixth Generation in an attempt to reflect upon recent conceptualizations of gender as well as contemporary changes in society mainly due to globalization and the impact of feminism and gay movements. The limited literature focused on Mexican masculinities has overlooked the importance of theatre as a privileged and productive setting for the study of gender. Another common factor in studies dedicated to the representation of Mexican men in literature is the focus …

Physiological And Subjective Aspects Of Positive Mood In Relation To Executive Functioning: The Potential Moderating Role Of Personality, Luz Helena Ospina

Dissertations, Theses, and Capstone Projects

Positive affect has been demonstrated to improve aspects of cognition. However, recent studies reveal that positive affect may hinder the same cognitive processes, such as executive functioning, memory and creativity. These discrepant findings may be due to differing levels of physiological arousal, a component of the circumplex model of affect, which has been largely ignored in affective research. For example, one recent study suggests that positive valence coupled with varying levels of physiological arousal (i.e., low, moderate, and high) may differentially affect performance on tasks of verbal fluency and memory. Furthermore, one other explanation for these inconsistent findings may relate …
