United States Geological Survey: Staff Publications

The Gulf Sturgeon, Acipenser oxyrinchus desotoi, is an anadromous species of Acipenseridae and native to North America. It currently inhabits and spawns in the upper reaches of seven natal rivers along the northern coast of the Gulf of Mexico from the Suwannee River, Florida, to the Pearl River, Louisiana, during spring to autumn. Next to the Alligator Gar (Atractosteus spatula), the Gulf Sturgeon is currently the largest fish species occurring in U.S. Gulf Coast rivers, attaining a length of 2.35 m and weights exceeding 135 kg, but historically attained a substantially larger size. Historically, the spawning populations existed in additional …

Viral Zoonoses That Fly With Bats: A Review, Alfonso Calderon, Camilo Guzman, Jorge Salazar-Bravo, Luiz Tadeu Figueiredo, Salim Mattar, German Arrieta

MANTER: Journal of Parasite Biodiversity

Emerging infectious diseases are a growing threat to human health and a great challenge for global medical attention systems. Governmental agencies in tropical regions with abundant zoonotic pathogens should implement an active vigilance/monitoring model in bat reservoir populations because of their species richness, abundance and dispersal capabilities. Chiropterans represent approximately 20% of all mammal species, the second largest order in terms of number of species after rodents. Importantly, bats constitute natural reservoirs for potential infection of humans of several infectious disease agents such as Coronavirus, Filovirus, Lyssavirus, Paramyxovirus, and Flavivirus. Local disease outbreaks caused by new pathogens can …

Detection And Characterization Of Circulating Tumor Associated Cells In Metastatic Breast Cancer., Zhaomei Mu, Naoual Benali-Furet, Georges Uzan, Anaëlle Znaty, Zhong Ye, Carmela Paolillo, Chun Wang, Laura Austin, Giovanna Rossi, Paolo Fortina, Hushan Yang, Massimo Cristofanilli

Department of Medical Oncology Faculty Papers

The availability of blood-based diagnostic testing using a non-invasive technique holds promise for real-time monitoring of disease progression and treatment selection. Circulating tumor cells (CTCs) have been used as a prognostic biomarker for the metastatic breast cancer (MBC). The molecular characterization of CTCs is fundamental to the phenotypic identification of malignant cells and description of the relevant genetic alterations that may change according to disease progression and therapy resistance. However, the molecular characterization of CTCs remains a challenge because of the rarity and heterogeneity of CTCs and technological difficulties in the enrichment, isolation and molecular characterization of CTCs. In this …

Models And Methods In Cultural And Social Evolution, Elliot G. Aguilar

Dissertations, Theses, and Capstone Projects

Chapter 1 The mathematical study of genealogies has yielded important insights in population biology, such as the ability to estimate the time to the most recent common ancestor (MRCA) of a sample of genetic sequences or of a group of individuals. Here we introduce a model of cultural genealogies that is a step toward answering similar questions for cultural traits. In our model individuals can inherit from a variable, potentially large number of ancestors, rather than from a fixed, small number of ancestors (one or two) as is typical of genetic evolution. We first show that, given a sample of …

Probing The Structure And Photophysics Of Porphyrinoid Systems For Functional Materials, Christopher D. Farley

Dissertations, Theses, and Capstone Projects

Porphyrins (Pors) and their many cousins, including phthalocyanines (Pcs), corroles (Cors), subphthalocyanines (SubPcs), porphyrazines (Pzs), and naphthalocyanines (NPcs), play amazingly diverse roles in biological and non-biological systems because of their unique and tunable physical and chemical properties. These compounds, collectively known as porphyrinoids, can be employed in any number of functional devices that have the potential to address the challenges of modern society. Their incorporation into such devices, however, depends on many structural factors that must be well understood and carefully controlled in order to achieve the desired behavior. Self-assembly and self-organization are key processes for developing these new technologies, …

The Role Of Individual Cognitive And Behavioral Ontogeny In Organization And Evolution Of Social Systems, Andrew G. Fulmer

Dissertations, Theses, and Capstone Projects

Exploration and explanation of the relationship between individual variation in behavior and the composition and adaptive success of social groups or populations are crucial problems in the fields of behavioral ecology, ethology, and comparative psychology. These questions have been the subject of a longstanding discussion at both the proximate and ultimate levels of inquiry. Adaptive mechanisms explaining social decision making, both in terms of affiliative and competitive partner choices, are at the center of such discussions. Inclusive fitness, kin-selection, handicap or prestige, risk seeking and risk avoiding strategies, pay-to-stay/reward principles, as well as other theories have been proposed and supported …

Computerized Classification Of Surface Spikes In Three-Dimensional Electron Microscopic Reconstructions Of Viruses, Younes Benkarroum

Dissertations, Theses, and Capstone Projects

The purpose of this research is to develop computer techniques for improved three-dimensional (3D) reconstruction of viruses from electron microscopic images of them and for the subsequent improved classification of the surface spikes in the resulting reconstruction. The broader impact of such work is the following.

Influenza is an infectious disease caused by rapidly-changing viruses that appear seasonally in the human population. New strains of influenza viruses appear every year, with the potential to cause a serious global pandemic. Two kinds of spikes – hemagglutinin (HA) and neuraminidase (NA) – decorate the surface of the virus particles and these proteins …

Seeking Holiness: The Contribution Of Nine Vernacular Narrative Texts From The Twelfth To The Fourteenth Centuries, Stephanie Grace Petinos

Dissertations, Theses, and Capstone Projects

Spirituality has been increasingly studied to determine the laity’s role within Church history in the Middle Ages. However, secular literature is often overlooked as a source of understanding lay spirituality, even though it is a crucial aspect of cultural and social history. I fill this gap by analyzing nine important vernacular texts to uncover several distinctive definitions of holiness, all of which blend the religious and the secular. Close reading of these texts reveals various paths to holiness, which undermine the Church’s attempts at sole control over spirituality. This study demonstrates that secular authors were concerned with exploring spiritual matters; …

Adult Neurogenesis In Avian Auditory Cortex, Caudomedial Nidopallium (Ncm): Lateralization And Effects Of Statins, Shuk C. Tsoi

Dissertations, Theses, and Capstone Projects

In the first part of this paper, we investigated the basic relationship between learning, memory and adult neurogenesis using zebra finches. We found that in the auditory cortex, the left hemisphere had more new neurons than the right hemisphere. This lateralization was correlated with song learning and memory. In the second part, we used juvenile zebra finches as a model organism to study the effects of Lipitor on learning, memory and neurogenesis. We found that Lipitor impaired song learning and memory storage. Lipitor treatments also changed the morphology of new neurons and size of old neurons, suggesting statins may affect …

In Search Of Argentinidad: Identity Affirming Bodies In Movement In Latino-America, Melissa Maldonado-Salcedo

Dissertations, Theses, and Capstone Projects

This project is a multi-sited investigation into the production of Argentinidad (the embodied feeling of Argentine national identity) post the economic crisis of 2001 known as el Argentinazo. A special attention is paid to the role of the body as a culturally and socially mediated site of identity formation. Additionally, this project engages with the intersections of cultural and psychoanalytic theories that have influenced Argentinean self-identity in addition to social identities that are negotiated in moments of personal and national crisis. This project examines the roles and relationships of family and migration within Argentinean diasporic communities originating from the Provinces …

Feeling Political: Affect, Emotion, And Ethics In Western Political Theory, John Mcmahon

Dissertations, Theses, and Capstone Projects

What conceptual and methodological resources would it take for political theory to be able to more deeply analyze the emotional and affective dimensions of political life? In this dissertation, I articulate interdisciplinary work on affect and emotion into political theory in order to realize four linked objectives: first, to develop a method of reading and interpreting political theory capable of tracing the theoretical work done by affect and emotion in works of political thought; second, to reassess the boundaries of the political theory canon in terms of the thinkers that ‘count’ as part of that canon as well as the …

Seeing And Perceptual Content, Ben S. Phillips

Dissertations, Theses, and Capstone Projects

There are two widely held assumptions about perception: ascriber-independence (the view that the facts regarding what a subject perceives, as well as what her perceptual states represent, are independent of the interests of those attributing the relevant states to her), and determinacy (the view that perceptual content is relatively determinate). I challenge both of these assumptions, and develop a new approach to perceptual content, with implications for theories of mental content more broadly. In chapter one, I address the question of whether, in addition to low-level features, vision represents ordinary objects. I argue that there is just no fact of …

Sex Differences In Stress, Burnout And Coping In Emergency Medical Service Providers, Celia R. Sporer

Dissertations, Theses, and Capstone Projects

The physical and psychological wellbeing of emergency medical service (EMS) providers is important for sustaining the overall model of emergency responding as well as providing consistent quality patient care. Despite the importance of the role, very little research has been undertaken for this occupational group. In particular, very little research on stress, burnout and coping have been undertaken. The failure to examine these areas fully has resulted not only in gaps in the literature but also practical failure for providers and the populations they serve. The assumption that EMS providers work under stressful circumstances which can result in burnout and …

Examining Relationships Between Basic Emotion Perception And Musical Training In The Prosodic, Facial, And Lexical Channels Of Communication And In Music, Jamie Twaite

Dissertations, Theses, and Capstone Projects

Research has suggested that intensive musical training may result in transfer effects from musical to non-musical domains. There is considerable research on perceptual and cognitive transfer effects associated with music, but, comparatively, fewer studies examined relationships between musical training and emotion processing. Preliminary findings, though equivocal, suggested that musical training is associated with enhanced perception of emotional prosody, consistent with a growing body of research demonstrating relationships between music and speech. In addition, few studies directly examined the relationship between musical training and the perception of emotions expressed in music, and no studies directly evaluated this relationship in the facial …

Emotion Regulation In Relation To Cognitive Functioning In The Preclinical Stages Of Dementia, Erica P. Meltzer

Dissertations, Theses, and Capstone Projects

Emotion regulation (ER) is essential for effective functioning in daily life. Research suggests that ER improves in older adulthood despite concomitant declines in cognition and the presumed neural substrates of ER. The current understanding of ER in older adulthood, and particularly of the relationship between ER and cognition in older adulthood, is limited. This is likely because the construct of ER is challenging to operationalize and, therefore, difficult to study.

The current study investigates ER in relation to cognitive functioning, specifically executive functioning and memory, in individuals with varying degrees of cognitive difficulties (i.e., in the preclinical stages of dementia). …

Medication Management In Pediatric Chronic Illness: Should Patient Anxiety Be Considered?, Claire J. Hoogendoorn

Dissertations, Theses, and Capstone Projects

Introduction: There is growing support that psychological symptoms can impact various aspects of disease, well-being, and medical treatment for those with a chronic illness like Crohn’s disease (CD). Yet, almost no studies have examined whether psychological symptoms can influence management or efficacy of patient medication regimens. The aims of this project were to examine whether anxiety predicted pediatric patients’ level of medication management, medication prescription changes, and corticosteroid prescription and duration.

Method: A total of 105 pediatric patients ages 8-18 (M=14.5, SD=2.3) completed a validated anxiety questionnaire during a GI office visit (baseline). Prescribed IBD …

Screening Male Crisis: A Comparative Analysis Of The Alternative Coming-Of-Age Motion Picture, Matthew J. Tesoro

Dissertations, Theses, and Capstone Projects

This thesis will identify how the principle male character in select film narratives transforms from childhood through his adolescence in multiple locations and historical eras. The primary film narratives include Satyajit Ray’s Apu Trilogy: Pather Panchali (1955), Aparajito (1956), and Apur Sansar (1959), François Truffaut’s "Antoine Doinel" cycle: Les Quatre cents coups (1959), Antoine et Colette (1962), Baisers volés (1968), Domicile conjugal (1970), and L’Amour en fuite (1979), and Richard Linklater’s Boyhood (2014). These images of experience/maturation in motion are all intended to exemplify how the boy physically and psychologically changes over an extended period of time. The concept of …

Possible Underlying Mechanisms Of Hyperactivity In Children With Adhd, Nicole Feirsen

Dissertations, Theses, and Capstone Projects

Conceptualizations of Attention-Deficit/Hyperactivity Disorder (ADHD) have evolved significantly over the years. Historically, early conceptualizations of ADHD described hyperactivity as the core symptom of the disorder. However, when the third version of the Diagnostic and Statistical Manual of Mental Disorders (DSM) was published (1980), hyperactivity became a specific qualifier of the disorder and was no longer necessary for a diagnosis. Despite this shift in conceptualization of the disorder, there is an abundance of empirical evidence, both recent and historical, supporting the fact that hyperactivity is an enduring and clinically impairing symptom domain in ADHD. Despite having numerous validated instruments available to …

Identity In Sociocultural Context: Life Stories Of Korean Youth In New York City, Hannah Hyunkyung Kim

Dissertations, Theses, and Capstone Projects

Despite the increasing number of Korean immigrants and children of Korean parents in the United States, there has been a dearth of research on these youth. The identity of Korean American youth has gained even less attention despite of its developmental importance. This research started from a recognition that the identity of Korean American youth has never been studied through their life stories. Thus, the goal of this research was to understand the identity of Korean youth in New York City through their life stories. I investigated how their life stories developed and what influences affected their identities while growing …

Perspectives On Iraq's Past, Present, And Future In The Works Of Muhammad Baqir Al-Sadr And Yusuf Salman Yusuf, Amnah Almukhtar

Dissertations, Theses, and Capstone Projects

Through a look at the writings of Muhammad Baqir al-Sadr and Yusuf Salman Yusuf, I argue that Iraq’s communists and Islamists during the middle of the twentieth century could not escape a common language, common circumstances and conditions which framed their conceptions of the relationship between their pasts, presents, and futures. Their political visions did not come from their disparate traditions, although couched in those terms, but from their common circumstances and struggles towards the establishment of a sovereign, independent Iraqi nation. Despite their disagreements or variously framed answers, they were guided by similar questions. Yusuf Salman Yusuf, also known …

The Islamic Law Perspective Of Precautionary Principle On Transboundary Movement Of Living Modified Organisms (Lmos), Sri Wartini

Jurnal Hukum & Pembangunan

The aim of the research is to examine the Islamic law perspective of precautionary principle on transboundary movement of living modified organisms (hereinafter LMOs) based on maslahah mursalah (public interest) and sadd al-dhara’i (blocking the means). The international trade of LMOs may affect the human health and environment in the importing states. Most of the importing states are Muslim states. Thus, it is important to examine the transboundary movement of LMOs from the Islamic law perspective. In order to elaborate on the issue, the reseach addresses the following questions: First, how is the relationship between man and nature (khalīfahand nature)? …

Electronic, Optical, And Magnetic Neural Interfaces, Polina Anikeeva

Amgen Seminar Series in Chemical Engineering

Mammalian nervous system contains billions of neurons that exchange electrical, chemical and mechanical signals. Our ability to study this complexity is limited by the lack of technologies available for interrogating neural circuits across their diverse signaling modalities without inducing a foreign-body reaction. My talk will describe neural interface strategies pursued in my group aimed at mimicking the materials properties and transduction mechanisms of the nervous system. Specifically, I will discuss (1) Fiber-based probes for multifunctional interfaces with the brain and spinal cord circuits; (2) Magnetic nanotransducers for minimally invasive neural stimulation; and (3) Active scaffolds for neural tissue engineering and …

Intellectual Property Rights For New Seed Technologies: Balancing Farmers’ And Breeders’ Rights, Preethi Krishnan, Andrew Raridon, Leigh Raymond, Mangala Subramaniam

Purdue Policy Research Institute (PPRI) Policy Briefs

Many cite improved seed technologies as vital to addressing the challenge of food insecurity, especially when faced with combined stresses of global climate change, population growth, and natural resource depletion (Anthony and Ferroni 2012; Lipton 2007). As improved seeds find their way into the developing world, policymakers are struggling to find the appropriate institutional mechanisms to regulate their creation and use. Arguments over intellectual property rights (IPR) are central to this debate. Some activists in the Global South are distrustful of any IPR regime that creates private ownership over seeds, whereas international financial institutions such as the World Trade Organization …

Review Of The Gender And Social Impacts Of Improved Seed Technology In Developing Countries: Policy Implications, Preethi Krishnan, Andrew Raridon, Leigh Raymond, Mangala Subramaniam

Purdue Policy Research Institute (PPRI) Policy Briefs

Experts have acknowledged the limits to growth that the processes of climate change, population expansion, and resource depletion will place on agricultural producers in the 21^st century (FAO 2012). In response, scientists are employing biotechnology to create new improved seed varieties. However, developing improved seed technology (IST) involves complex and controversial issues that span across disciplines in the biological and social sciences (see Box 1). In this policy brief, we emphasize the need to better examine the gender and social impacts of advancements in seed technology. Based on a detailed review of the literature, we determine that despite recent …
