Over-Imitation In Four-To-Six-Year-Old Children With Autism And Typically Developing Children, Tamara Henschell

Rehabilitation, Human Resources and Communication Disorders Undergraduate Honors Theses

This study is a follow-up based on research conducted by Horner and Whiten in 2005. Nearly identical methods and materials from that study were used to compare the over-imitation behaviors of preschool children with autism to age-matched typically developing (TD) children. Contrary to the hypothesis, the children with autism were found to over-imitate at the same rates as the TD group. However, several limitations were found in this study that may have influenced the results, including small sample size, test location, and previous training. Keywords: autism spectrum disorders, imitation, over-imitation, emulation

Design Science In Human-Computer Interaction: A Model And Three Examples, Nathan Prestopnik

School of Information Studies - Dissertations

Humanity has entered an era where computing technology is virtually ubiquitous. From websites and mobile devices to computers embedded in appliances on our kitchen counters and automobiles parked in our driveways, information and communication technologies (ICTs) and IT artifacts are fundamentally changing the ways we interact with our world. Indeed, the world itself changing, becoming ever more artificial. It is a designed world that we have created for ourselves.

Human-computer interaction (HCI) scholars are concerned with the interactions that occur between people and technology in this new world: how do IT artifacts impact the human experience, and how can knowledge …

An Investigation Of Digital Reference Interviews: A Dialogue Act Approach, Keisuke Inoue

School of Information Studies - Dissertations

The rapid increase of computer-mediated communications (CMCs) in various forms such as micro-blogging (e.g. Twitter), online chatting (e.g. digital reference) and community- based question-answering services (e.g. Yahoo! Answers) characterizes a recent trend in web technologies, often referred to as the social web. This trend highlights the importance of supporting linguistic interactions in people's online information-seeking activities in daily life - something that the web search engines still lack because of the complexity of this hu- man behavior. The presented research consists of an investigation of the information-seeking behavior of digital reference services through analysis of discourse semantics, called dialogue acts, …

Genetic Structure In The Coral, Montastraea Cavernosa: Assessing Genetic Differentiation Among And Within Mesophotic Reefs, Daniel A. Brazeau, Michael P. Lesser, Marc Slattery

Pharmaceutical Sciences Faculty Publications

Mesophotic coral reefs (30–150 m) have recently received increased attention as a potential source of larvae (e.g., the refugia hypothesis) to repopulate a select subset of the shallow water (,30 m) coral fauna. To test the refugia hypothesis we used highly polymorphic Amplified Fragment Length Polymorphism (AFLP) markers as a means to assess small-scale genetic heterogeneity between geographic locations and across depth clines in the Caribbean coral, Montastraea cavernosa. Zooxanthellae-free DNA extracts of coral samples (N = 105) were analyzed from four depths, shallow (3–10 m), medium (15– 25 m), deep (30–50 m) and very deep (60–90 m) from Little …

Climate Change Tipping Points: A Point Of No Return?, Elise Lequire

Joint Fire Science Program Digests

Summer 2012 saw records fall for intensity of drought and number, size, and cost of wildfires in the Central and Western United States, and the climate forecast calls for more of the same in the near and distant future. When wildfire breaks out, emergency responders decide their immediate strategy based on past experience and quick judgment calls. But in the long term, land managers need to plan for a warmer climate on a time scale of decades, or even a century or more, to better reflect the life span of trees and forests. Studies supported by the Joint Fire Science …

An Assessment Of The Economics Of Natural And Built Infrastructure For Water Resources In Maine, Charles S. Cogan Phd, Damon Yakovleff Mcpd, Samuel B. Merrill Phd

Water

Dispersed population growth has spread the need for new systems across the landscape, creating stresses on both the quantity and quality of Maine’s historically abundant groundwater and surface water supplies. Steps to address the inadequacies of these systems to manage stormwater flows are long overdue.

This report concludes that there are numerous opportunities for Maine to meet the demands for new, upgraded, and expanded water resources management and to do so at much lower costs than is often thought (or feared) possible. Four aspects of water resources are examined in the report: 1. Maintaining drinking water quality 2. Mitigating good …

Diabetic Db/Db Mice Exhibit Central Nervous System And Peripheral Molecular Alterations As Seen In Neurological Disorders., A. Ernst, Ajaykumar Narayan Sharma, Khalid M. Elased, P. C. Guest, H. Rahmoune, S. Bahn

Pharmacology and Toxicology Faculty Publications

The db/db mouse is a widely used preclinical model in diabetes research. Recent studies have shown that these mice also display aspects of psychosis and depression-like behaviors as seen in some psychiatric disorders. Here, we have performed multiplex immunoassay and liquid chromatography mass spectrometry profiling of the plasma and brain samples from db/db and control mice to identify altered pathways, which could be related to these behavioral abnormalities. This is the first study to carry out profiling of the brain proteome in this model. Plasma from the db/db mice had increased levels of leptin and insulin, decreased levels of peptide …

Habitat Characterization, Habitat Use And Associated Growth Of Juvenile Spotted Seatrout (Cynoscion Nebulosus) In A Mississippi Bay System: Implications For Stock Enhancement Practices, Joseph Read Hendon

Dissertations

The spotted seatrout (Cynoscion nebulosus) is the most targeted recreational fishery species in Mississippi coastal waters. Consequently, the Seatrout Population Enhancement Cooperative stock enhancement program was initiated to investigate methods for supplementing this heavily exploited population. Given ecological data needs for both wild and hatchery-reared (HR) juveniles of the species, habitat mapping, directed sampling and a caging study were conducted. Submerged aquatic vegetation (SAV), oyster shell and non-vegetated substrates were mapped at water depths < 2 m in Point aux Chenes Bay, Mississippi, using a sidescan sonar, which provided more accurate estimations of habitat coverage, particularly for SAV, compared to point-based sampling. Applying habitat strata delineated from sidescan mapping, late-juvenile spotted seatrout [125 - 275 mm total length (TL)] were sampled in SAV, marsh-edge and non-vegetated habitats as part of a seasonal gill net survey conducted in 2011 and 2012. Spotted seatrout ranging from 138 to 485 mm TL were collected using a smallmesh gill net, and 65% of collected individuals fell within the targeted late-juvenile size range. Overall mean catch-per-unit-effort of C. nebulosus did not differ for abundance or biomass between years, but both metrics were significantly higher in SAV habitats. Employing cage enclosures that …

Community Metrics And Trophic Dynamics In Tidal Creeks In An Anthropogenically Fragmented, Coastal Landscape, Michael Robert Lowe

Dissertations

Salt marsh landscapes are among the most anthropogenically altered ecosystems in the world. Urbanization (i.e., accumulation of impervious cover and man made structrues) of the coastal landscape can disrupt the delivery of numerous ecosystem services. Among the many services provided by salt marsh habitats, they serves as the primary habitats for distinct macroinfauna (i.e., benthic and epibenthic macrofauna) and nekton (i.e., fish and decapod crustaceans) assemblages. In this dissertation, I used a number of metrics to test the overarching hypothesis that coastal urbanization has negative consequences for salt marsh faunal assemblages. Chapter I uses a landscape ecology approach to show …

Deposition And Fate Of Atmospheric Mercury In Forested Landscapes Of The Adirondack Park, Ny, Bradley Blackwell

Civil and Environmental Engineering - Dissertations

In this dissertation, I investigated the deposition and fate of atmospheric mercury (Hg) to forested landscapes of the Adirondack region in Upstate New York. Despite the fact that forests are the dominant land cover in North America, there has been relatively little research on the deposition, transport, and fate of Hg within forested ecosystems. The objective of this dissertation was to quantify pathways of Hg deposition in forested sites in the Adirondack Park and to examine spatial and geographic patterns of Hg deposition and fate.

The research for this dissertation was conducted in three phases. In Phase One, I compared …

I. Stereochemical Control Of Chiral Assembly And Liquid Crystal Phase Formation Of Nonamphiphilic Molecules In Water Ii. Control Bacterial Quorum Sensing And Quorum Sensing-Mediated Activities Using Small Unnatural Molecules, Sijie Yang

Chemistry - Dissertations

The primary goal of this research is to utilize organic synthesis as a tool to prepare small molecules that find potential application in different areas including colloidal and material science, biological chemistry, and medicinal chemistry.

Chapter 1 describes the interpretation of the conformation of nonamphiphilic mesogen disodium cromoglycate (5´DSCG) when it exists as part of an assembly in water. The study of thermodynamic incompatibility and miscibility suggest that a previously proposed model for the assembly of 5´DSCG may be applicable to nonamphiphilic organic dyes and other mesogens.

Chapter 2 presents a study of stereochemical control on assembly and liquid crystal …

Coping With College Stress: Does Sense Of Coherence Influence The Use Of Alcohol And Otc Medication?, Rebecca Silver

Psychology - Dissertations

The combination of stress and psychological symptoms (e.g., anxiety, depression) have been associated with alcohol consumption and the nonindicated use of over the counter (OTC) medications. However, some people have personal resources that contribute to a successful management of the stress response. Antonovsky's (1987) salutogenic theory proposes that a person's sense of coherence (SOC) buffers the relationship between stress appraisal and stressor-induced reactions. This study examined the SOC in relation to associations of stress-related indices with substance-related coping behaviors. One hundred and sixty-five college student participants completed questionnaires that assessed their demographics, stressors, perceived stress, SOC, psychological/physical symptoms, as well …

Molecular Sensing With Protein And Solid-State Nanopores, David John Niedzwiecki

Physics - Dissertations

In the past 15 years nanopore sensing has proven to be a successful method for probing a variety of molecules of biological interest, such as DNA, RNA and proteins. Of particular appeal is this technique's ability to probe these molecules without the need for chemical modification or labeling, to do so at physiological conditions, and to probe single molecules at a time, allowing the possibility for results masked in bulk measurements to come to light. In this thesis these advantageous properties will be used in work on both a synthetic (solid-state) nanopore system and an engineered biological nanopore. I will …

Cell Mechanics: From Cytoskeletal Dynamics To Tissue-Scale Mechanical Phenomena, Shiladitya Banerjee

Physics - Dissertations

This dissertation explores the mechanics of living cells, integrating the role of intracellular activity to capture the emergent mechanical behavior of cells. The topics covered in this dissertation fall into three broad categories : (a) intracellular mechanics, (b) interaction of cells with the extracellular matrix and (c) collective mechanics of multicellular colonies. In part (a) I propose theoretical models for motor-filament interactions in the cell cytoskeleton, which is the site for mechanical force generation in cells. The models predict in a unified manner how contractility, dynamic instabilities and mechanical waves arise in the cytoskeleton by tuning the activity of molecular …

Hybrid Seeker Optimization Algorithm For Global Optimization, Milan Tuba, Ivona Brajevic, Raka Jovanovic

Applied Mathematics & Information Sciences

Swarm intelligence algorithms have been succesfully applied to hard optimization problems. Seeker optimization algorithm is one of the latest members of that class of metaheuristics and it has not yet been thorougly researched. Since the early versions of this algorithm were less succesful with multimodal functions, we propose in this paper hybridization of the seeker optimization algorithm with the well known artificial bee colony (ABC) algorithm. At certain stages we modify seeker’s position by search formulas from the ABC algorithm and also modify the inter-subpopulation learning phase by using the binomial crossover operator. Our proposed algorithm was tested on the …

Brown Algal Diversity In Bermuda Revealed Using Molecular Tools, Alyssa L. Rogers

Senior Honors Projects

For nearly 60 years there has been very little investigation of the marine algal flora in Bermuda, which is an ideal location for a biodiversity assessment due to its size and location. Residing approximately 1000km off the coast of North Carolina, Bermuda is influenced by the cool water from the north during winter and by the warm water eddies that spin off the Gulf Stream for the much of the other seasons. The Bermuda Seaweed Project aims to extensively survey the marine algal flora in Bermuda and generate morphological and molecular data for all three major groups of macroalgae present. …

A secondary purpose was to determine what their beliefs and perceptions were in regards to lifting weights. Participants were college-aged females ranging in age from 17-29 years. Observations of weight lifting activities were conducted during peak hours of operation (Mondays, Wednesdays, and Fridays from 3- 6pm) in the fitness facility. A total of 60 hours of observations were conducted over a period of four weeks. In addition to observations, two focus groups were conducted. Participants were divided into two specific groups: I …

Deconstructing Mtor Complexes In Regulation Of Glioblastoma Multiforme And Its Stem Cells, Meena Jhanwar-Uniyal, Dhruve Jeevan, Jayson Neil, Craig Shannon, Ladislau Albert, Raj Murali

NYMC Faculty Publications

Atypical serine-threonine kinase, mTOR (mechanistic target of Rapamycin; originally coined "mammalian TOR"), exists in two distinct multi-protein complexes termed mTOR complex 1 (mTORC1) and 2 (mTORC2), that senses and integrates a variety of environmental signals to control organism growth and homeostasis via non-overlapping signaling pathways. mTOR belongs to the phosphoinositide 3-kinase (PI3-K)-related kinase family, and an aberrant activation of mTORC1 is a potential contributing factor in uncontrolled cell growth, proliferation, and survival of tumor cells via specific effects on cap-dependent translation initiation, as well as in a more sustained manner via advancing ribosome biogenesis. It is thereby shown to be …

Grandma's "Pill", Whitney Mills

Perspectives

This is a qualitative study that explores the experiences of women and the creation of the birth control pill. The study results from interviews with three women over the age of sixty-five, all of which were of reproductive age during the unveiling of the contraceptive pill in the United States. Results from the study suggest that the creation of the pill was an empowering historical event for womanhood in the United States. This paper explores the multifaceted freedom that the pill brought to women during the mid to late 20th century, and also suggests that the introduction of the contraceptive …
