Maize And Stone A Functional Analysis Of The Manos And Metates Of Santa Rita Corozal, Belize, Lisa Glynns Duffy Jan 2011

Maize And Stone A Functional Analysis Of The Manos And Metates Of Santa Rita Corozal, Belize, Lisa Glynns Duffy

Electronic Theses and Dissertations

The manos and metates of Santa Rita Corozal, Belize are analyzed to compare traditional maize-grinding types to the overall assemblage. A reciprocal, back-and-forth grinding motion is the most efficient way to process large amounts of maize. However, rotary movements are also associated with some ground stone implements. The number of flat and trough metates and two handed manos are compared to the rotary-motion basin and concave type metates and one-handed manos to determine predominance and distribution. Flat is the predominant type and, together with the trough type, these grinding stones make up the majority of metates at the site. Manos …

Effects Of 3d Stereoscopy, Visuo-Spatial Working Memory, And Perceptions Of Simulation Experience On The Memorization Of Confusable Objects, Joseph R. Keebler

Electronic Theses and Dissertations

This dissertation investigated the impact of active stereoscopic 3-dimensional (3D) imagery equipment and individual differences in visuo-spatial working memory (VSWM) capacity on retention of a set of similar, novel objects (i.e., armored military vehicles). Seventy-one participants were assessed on their visuo-spatial working memory using the Visual Patterns Test (Della Sala, Gray, Baddeley, & Wilson, 1997). They were then assigned to one of four different conditions (3D high VSWM, 3D low VSWM, 2D high VSWM, 2D low VSWM) based upon their visuo-spatial working memory. Participants were then trained to identify military vehicles using a simulation that presented the training stimuli in …

Use Of Vegetative Mulch As Daily And Intermediate Landfill Cover, Assal Edwar Haddad Jan 2011

Use Of Vegetative Mulch As Daily And Intermediate Landfill Cover, Assal Edwar Haddad

Electronic Theses and Dissertations

Management of yard waste is a significant challenge in the US, where in 2008 13.2% of the 250 million tons of municipal solid waste (MSW) was reported to be yard waste. This study describes research conducted in the laboratory and field to examine the application of vegetative mulch as daily and intermediate landfill cover. Mulch was found to exhibit stronger physical properties than soil, leading to a more stable landfill slope. Compaction of mulch was found to be significantly greater than soil, potentially resulting in airspace recovery. Degradation of mulch produced a soil-like material; degradation resulted in lower physical strength …

A Contextual Approach To Learning Collaborative Behavior Via Observation, Cynthia L. Johnson Jan 2011

A Contextual Approach To Learning Collaborative Behavior Via Observation, Cynthia L. Johnson

Electronic Theses and Dissertations

This dissertation describes a novel technique to creating a simulated team of agents through observation. Simulated human teamwork can be used for a number of purposes, such as expert examples, automated teammates for training purposes and realistic opponents in games and training simulation. Current teamwork simulations require the team member behaviors be programmed into the simulation, often requiring a great deal of time and effort. None are able to observe a team at work and replicate the teamwork behaviors. Machine learning techniques for learning by observation and learning by demonstration have proven successful at observing behavior of humans or other …

Intelligent Design, Jillian Amistoso Dudziak

Electronic Theses and Dissertations

As human beings we are designed and created in a fabric that is profound and complex. We are built with a framework where mind and body work in a concerted effort to maintain our lives automatically. A deep and defining part of our existence as humans is not just the innate desire to live but to live in consistent well-being--emotionally, physically, and mentally. I believe when we incorporate our knowledge of human physiology into our creative process then we allow ourselves a greater opportunity to create an authentic connection with our intended audience. My work during the past three years …

Somali Piracy And The Introduction Of Somalia To The Western World, Daniel A. Jean-Jacques Jan 2011

Somali Piracy And The Introduction Of Somalia To The Western World, Daniel A. Jean-Jacques

Electronic Theses and Dissertations

This thesis investigates the origins of the modern phenomenon of Somali piracy within a deeper historical context. More specifically, this analysis concentrates on the development of piracy in the north of the country. It is here contended that Somali piracy is, in fact, the product of the confluence of three historical currents. The first of these currents is the progressive degeneration of traditional Somali institutions due to exposure to the colonial and global markets. The second is the increasing reliance of northern Somalis on maritime resources due to over exploitation of the land and the fishing initiatives of the Barre …

Bayesian Model Selection For Classification With Possibly Large Number Of Groups, Justin Kyle Davis Jan 2011

Bayesian Model Selection For Classification With Possibly Large Number Of Groups, Justin Kyle Davis

Electronic Theses and Dissertations

The purpose of the present dissertation is to study model selection techniques which are specifically designed for classification of high-dimensional data with a large number of classes. To the best of our knowledge, this problem has never been studied in depth previously. We assume that the number of components p is much larger than the number of samples n, and that only few of those p components are useful for subsequent classification. In what follows, we introduce two Bayesian models which use two different approaches to the problem: one which discards components which have “almost constant” values (Model 1) and …

A Sense Of Place Ethnographic Reflection On Two Palestinian Life Histories, Patrick H. Barrett Jan 2011

A Sense Of Place Ethnographic Reflection On Two Palestinian Life Histories, Patrick H. Barrett

Electronic Theses and Dissertations

There is a labyrinth of complex social connections between people and places that deserves careful anthropological reflection. People do not simply occupy places; they experience them, infusing them with life and social meaning. Basso (1996:53) argues that ethnography has reported little about the complex ways in which people are “alive to the world around them.” Anthropology is currently experiencing a resurging emphasis on place that seeks to account for its remarkably social features. Rather than primarily thinking about place when determining a location for fieldwork, emerging anthropological reflection shows the discipline is repositioning itself to explore the complex and often …

An Analysis Of Factors That Influenced Brevard Students To Drop Out And Why They Returned To Earn Their General Education Development (Ged) Diploma, B L. Spadaccini Jan 2011

An Analysis Of Factors That Influenced Brevard Students To Drop Out And Why They Returned To Earn Their General Education Development (Ged) Diploma, B L. Spadaccini

Electronic Theses and Dissertations

Dropping out of high school almost guarantees a life of hardship. The absence of a diploma contributes to poverty, increased crime rates and weakens the economy. To that end, school districts have a moral and ethical responsibility to bring an end to the dropout epidemic. This study was based on an analysis of more than 26,000 Brevard public school students. The researcher used 2006-2007, 2007-2008 and 2008-2009 student data to determine the relationship between race, grade level, ESE status, ELL status, SES, type of promotion and dropping out of school. In addition, the researcher reviewed Student Exit Survey data and …

Development Of Molecular And Cellular Imaging Tools To Evaluate Gene And Cell Based Therapeutic Strategies In Vivo, Jixiang Xia Jan 2011

Development Of Molecular And Cellular Imaging Tools To Evaluate Gene And Cell Based Therapeutic Strategies In Vivo, Jixiang Xia

Electronic Theses and Dissertations

Molecular imaging modalities are important tools to evaluate the efficacy of gene delivery systems and cell-based therapies. Development and application of these modalities will advance our understanding of the mechanism of transgene expression and cell fate and functions. Physical gene transfer methods hold many advantages over viral vectors among gene therapeutic strategies. Here, we evaluated the efficacy of biolistic (“gene gun”) gene targeting to tissues with non-invasive bioluminescence imaging (BLI) methods. Plasmids carrying the firefly luciferase reporter gene were transfected into mouse skin and liver using biolistics, and BLI was measured at various time points after transfer. With optimized DNA …

New Perspectives On The Quatrefoil In Classic Maya Iconography The Center And The Portal, Rachel K. Egan Jan 2011

New Perspectives On The Quatrefoil In Classic Maya Iconography The Center And The Portal, Rachel K. Egan

Electronic Theses and Dissertations

The quatrefoil is a pan-Mesoamerican symbol with considerable time-depth. For the Maya, use of the symbol peaked during the Classic Period, reaching its highest frequency and largest geographical spread. Consequently, understanding its meaning has the potential to illuminate information about Precolumbian Maya worldview. While there have been several studies that focus on Preclassic Period quatrefoils, a similar study is lacking for Classic Period. Furthermore, the evaluations of the quatrefoil that do exist for the Classic Period are limited, often focusing on a select few examples. This thesis attempts to rectify the gap in extant research through an examination of the …

Art In The Light Of Knowing A Cognitive Approach To The Creative Process, Victor M. Knoe Jan 2011

Art In The Light Of Knowing A Cognitive Approach To The Creative Process, Victor M. Knoe

HIM 1990-2015

Art can be an elusive concept. Neither an outsider nor a professional artist is immune to abstractions in the attempt to describe it. Every individual must necessarily come from their own, unique perspective. The obstacles that we experience in defining the essence of art can be better understood if we see them as a gauge for our historical period. Given the limits of our contemporary conditions, it seems impossible that we may ever overcome the vast chasms that imprison us. We are discouraged to build bridges, at almost every turn, by the suggestive hopelessness of the abysmal distances between us. …

Crmp5 Regulates Generation And Survival Of Newborn Neurons In Olfactory And Hippocampal Neurogenic Areas Of The Adult Mouse Brain, Alexandra Veyrac, Sophie Reibel, Joelle Sacquet, Mireille Mutin, Jean-Philippe Camdessanche, Pappachan Kolattukudy, Jerome Honnorat, Francois Jourdan Jan 2011

Crmp5 Regulates Generation And Survival Of Newborn Neurons In Olfactory And Hippocampal Neurogenic Areas Of The Adult Mouse Brain, Alexandra Veyrac, Sophie Reibel, Joelle Sacquet, Mireille Mutin, Jean-Philippe Camdessanche, Pappachan Kolattukudy, Jerome Honnorat, Francois Jourdan

Faculty Bibliography 2010s

The Collapsin Response Mediator Proteins (CRMPs) are highly expressed in the developing brain, and in adult brain areas that retain neurogenesis, ie: the olfactory bulb (OB) and the dentate gyrus (DG). During brain development, CRMPs are essentially involved in signaling of axon guidance and neurite outgrowth, but their functions in the adult brain remain largely unknown. CRMP5 has been initially identified as the target of auto-antibodies involved in paraneoplasic neurological diseases and further implicated in a neurite outgrowth inhibition mediated by tubulin binding. Interestingly, CRMP5 is also highly expressed in adult brain neurogenic areas where its functions have not yet …

Social Implications From Agricultural Taskscapes In The Southwestern Amazon, John H. Walker Jan 2011

Social Implications From Agricultural Taskscapes In The Southwestern Amazon, John H. Walker

Faculty Bibliography 2010s

Across the Americas, but particularly in the Amazon Basin, precolumbian farmers invested their labor in features such as canals, causeways, and raised fields, creating agricultural landscapes. These landscapes required organized action in order to build and maintain them. Such actions can be usefully described as "tasks" to draw specific connections between communal work and landscape features (Ingold 1993). Using two parallel examples front the precolumbian Bolivian Amazon, this article presents landscape features as correlates of the variety and scale of tasks that compose the processes of creating and managing them. Data come from remote sensing and pedestrian survey. The execution …

Direct Patterning Of Coplanar Polyethylene Glycol Alkylsilane Monolayers By Deep-Ultraviolet Photolithography As A General Method For High Fidelity, Long-Term Cell Patterning And Culture, Kerry Wilson, Maria Stancescu, Mainak Das, John Rumsey, James Hickman

Faculty Bibliography 2010s

This manuscript details a general method for patterning coplanar alkylsilane monolayers using deep-ultraviolet photolithography that has broad application for high fidelity patterning of cells of varying phenotype in long-term cultures. A polyethylene glycol monolayer was formed on a silica substrate and then patterned using 193 nm light from an ArF excimer laser. The regions of photoablation were then rederivatized with (3-trimethoxysilyl propyl) diethyltriamine (DETA), yielding high contrast cytophilic islands that promoted cell adhesion and growth. Rat hippocampal neurons, motoneurons, and myoblasts were then cultured in a defined, serum-free medium on the patterned surfaces for periods in excess of 40 days. …

The Accuracy Of Climate Models' Simulated Season Lengths And The Effectiveness Of Grid Scale Correction Factors, Wade E. Winterhalter Jan 2011

The Accuracy Of Climate Models' Simulated Season Lengths And The Effectiveness Of Grid Scale Correction Factors, Wade E. Winterhalter

Faculty Bibliography 2010s

Global climate change is expected to impact biological populations through a variety of mechanisms including increases in the length of their growing season. Climate models are useful tools for predicting how season length might change in the future. However, the accuracy of these models tends to be rather low at regional geographic scales. Here, I determined the ability of several atmosphere and ocean general circulating models (AOGCMs) to accurately simulate historical season lengths for a temperate ectotherm across the continental United States. I also evaluated the effectiveness of regional-scale correction factors to improve the accuracy of these models. I found …

Evaluation Of Biolistic Gene Transfer Methods In Vivo Using Non-Invasive Bioluminescent Imaging Techniques, Jixiang Xia, Angela Martinez, Henry Daniell, Steven N. Ebert

Faculty Bibliography 2010s

Background: Gene therapy continues to hold great potential for treating many different types of disease and dysfunction. Safe and efficient techniques for gene transfer and expression in vivo are needed to enable gene therapeutic strategies to be effective in patients. Currently, the most commonly used methods employ replication-defective viral vectors for gene transfer, while physical gene transfer methods such as biolistic-mediated ("genegun") delivery to target tissues have not been as extensively explored. In the present study, we evaluated the efficacy of biolistic gene transfer techniques in vivo using non-invasive bioluminescent imaging (BLI) methods. Results: Plasmid DNA carrying the firefly luciferase …

Crmp5 (Collapsin Response Mediator Protein 5) Regulates Dendritic Development And Synaptic Plasticity In The Cerebellar Purkinje Cells, Naoya Yamashita, Bedrich Mosinger, Arpita Roy, Mari Miyazaki, Kozue Ugajin, Fumio Nakamura, Yukio Sasaki, Kazuhiko Yamaguchi, Pappachan Kolattukudy, Yoshio Goshima

Faculty Bibliography 2010s

Collapsin response mediator protein 5 (CRMP5) is one of the CRMP members that expresses abundantly in the developing brain. To examine the in vivo function of CRMP5, we generated crmp5-deficient (crmp5(-/-)) mice. Anti-calbindin immunofluorescence studies of crmp5(-/-) mice revealed aberrant dendrite morphology; specifically, a decrease in the size of soma and diameter of primary dendrite of the cerebellar Purkinje cells at postnatal day 21 (P21) and P28, but not at P14. Coincidentally, CRMP5 is detected in Purkinje cells at P21 and P28 from crmp5(+/-) mice. In cerebellar slices of crmp5(-/-) mice, the induction of long-term depression of excitatory synaptic transmission …

Expression And Characterization Of Antimicrobial Peptides Retrocyclin-101 And Protegrin-1 In Chloroplasts To Control Viral And Bacterial Infections, Seung-Bum Lee, Baichuan Li, Shuangxia Jin, Henry Daniell

Faculty Bibliography 2010s

Retrocyclin-101 (RC101) and Protegrin-1 (PG1) are two important antimicrobial peptides that can be used as therapeutic agents against bacterial and/or viral infections, especially those caused by the HIV-1 or sexually transmitted bacteria. Because of their antimicrobial activity and complex secondary structures, they have not yet been produced in microbial systems and their chemical synthesis is prohibitively expensive. Therefore, we created chloroplast transformation vectors with the RC101 or PG1 coding sequence, fused with GFP to confer stability, furin or Factor Xa cleavage site to liberate the mature peptide from their fusion proteins and a His-tag to aid in their purification. Stable …

Participation Of Mcp-Induced Protein 1 In Lipopolysaccharide Preconditioning-Induced Ischemic Stroke Tolerance By Regulating The Expression Of Proinflammatory Cytokines, Jian Liang, Jing Wang, Yasser Saad, Logan Warble, Edilu Becerra, Pappachan E. Kolattukudy

Faculty Bibliography 2010s

Background: Lipopolysaccharide (LPS) preconditioning-induced neuroprotection is known to be related to suppression of the inflammatory response in the ischemic area. This study seeks to determine if monocyte chemotactic protein-induced protein 1 (MCPIP1), a recently identified CCCH Zn finger-containing protein, plays a role in focal brain ischemia and to elucidate the mechanisms of LPS-induced ischemic brain tolerance. Methods: Transcription and expression of MCPIP1 gene was monitored by qRT-PCR and Western blot. Mouse microglia was prepared from cortices of C57BL/6 mouse brain and primary human microglia was acquired from Clonexpress, Inc. Wild type and MCPIP1 knockout mice were treated with LPS (0.2 …

Post-Transcriptional Regulation Of Igf1r By Key Micrornas In Long-Lived Mutant Mice, Ruqiang Liang, Amit Khanna, Senthilkumar Muthusamy, Na Li, Harshini Sarojini, John J. Kopchick, Michal M. Masternak, Andrzej Bartke, Eugenia Wang

Faculty Bibliography 2010s

Long-lived mutant mice, both Ames dwarf and growth hormone receptor genedisrupted or knockout strains, exhibit heightened cognitive robustness and altered IGF1 signaling in the brain. Here, we report, in both these long-lived mice, that three up-regulated lead microRNAs, miR-470, miR-669b, and miR-681, are involved in posttranscriptional regulation of genes pertinent to growth hormone/IGF1 signaling. All three are most prominently localized in the hippocampus and correspond to reduced expression of key IGF1 signaling genes: IGF1, IGF1R, and PI3 kinase. The decline in these genes expression translates into decreased phosphorylation of downstream molecules AKT and FoxO3a. Cultures transfected with either miR-470, miR-669b, …
