The Classroom Environment: The Silent Curriculum, Brittany Allen, Katie Hessick

Psychology and Child Development

This senior project focused on the physical environment of elementary school classrooms, with a particular emphasis on how environmental factors influence behavior and academic achievement. Such environmental factors included lighting, color, acoustics, temperature, seating arrangements, space and crowding, and living kinds such as plants and animals. Previous research has demonstrated a connection between student behavior and the classroom environment. Taylor and Vlastos (2009) developed a theory regarding the relationship between environment and design within the classroom. They referred to the physical environment of the classroom as the “silent curriculum” and hold strongly to the belief that understanding the physical environment …

Speak Up! Promoting Interactions During Shared Reading Activities, Jennifer Singleton

Psychology and Child Development

Interactions during shared reading activities between parent and child have been shown to benefit a child’s expressive vocabulary, receptive vocabulary, and literacy development. Research has identified a number of variables that influence the quality, frequency, and type of interactions that occur during shared reading. Using this research, I have written and illustrated a children’s book that accounts for these variables. The result is a 56 page, hard-covered book that reads from both directions. One direction prompts children to provide their own answer to why animals are the way they are, while the other direction offers the leading theories from scientists …

A Review Of Museum Literature And A Personal Critique. Museology: The Evolution Of A Socially Conscious Institution, Mckenna N. Friend

Social Sciences

This paper explores the relatively recent critical literature published on the history, theory, culture, and politics of museums. The report shall focus on comparing and contrasting curatorial methods as well as the before-and-after effect of the so-called “paradigm shift”—the shift from museums that are object-centered to visitor-centered [1]. This project emphasizes museums of Natural History and Anthropology, either by selecting literature that already references them or by applying the valid information in other articles. This emphasis allows for close evaluation of the exhibition of human evolution, cultural material, and Native Americans. How and why would a museum emphasize science over …

Magnetostatic Modeling for Microfluidic Device Design

Kirsten Marie Jackson

For several years, biologists have used superparamagnetic beads to facilitate biological separations. More recently, researchers have adopted this approach in microfluidic devices [1-3]. This recent development and use of superparamagnetic particles in biomedical and biological applications have resulted in a necessity for methods that enable the understanding and prediction of their properties and actions during use. Typically, such methods would involve simple experimentation prior to in vitro experimentation, animal testing, and finally clinical testing. To better understand and unleash this technology, COMSOL®, which is a finite element analysis and multiphysics simulation …

Because of the multitude of practical applications, the development of an undergraduate polymer chemistry laboratory focused on polyurethane elastomers is developed and described herein. Polymer chemistry students are exposed to hydroxyterminated polybutadiene (HTPB) …

Developing Digital Field Guides For Plants: A Study From The Perspective Of Users, Emily Roseanne Schwarz

Master's Theses

A field guide is a tool to identify an object of natural history. Field guides
cover a wide range of topics from plants to fungi, birds to mammals, and shells to minerals. Traditionally, field guides are books, usually small enough to be carried outdoors . They enjoy wide popularity in modern life; almost every American home and library owns at least one field guide, and the same is also true for other areas of the world.

At this time, companies, non-profits, and universities are developing computer
technologies to replace printed field guides for identifying plants. This thesis
examines the state …

A Neural Network Receiver For Em-Mwd Communication, Timothy P. Whitacre

Master's Theses

Baseband digital communication in electro-magnetic measurement while drilling (EM-MWD) systems is often corrupted by non-white surface noise. The inability to reliably decode the transmitted signals in a noisy environment limits the depth at which EM-MWD systems can operate. Correlation receivers, which are optimal in the presence of additive white Gaussian noise, can be sub-optimal in the presence of various types of field noise at different drilling sites.

This thesis investigates the application of artificial neural networks (ANN) as communication receivers in EM-MWD baseband digital communication systems. The performances of various ANN architectures and training algorithms are studied and compared with …

Active Pen Input And The Android Input Framework, Andrew S. Hughes

Master's Theses

User input has taken many forms since the conception of computers. In the past ten years, Tablet PCs have provided a natural writing experience for users with the advent of active pen input. Unfortunately, pen based input has yet to be adopted as an input method by any modern mobile operating system. This thesis investigates the addition of active pen based input to the Android mobile operating system.

The Android input framework was evaluated and modified to allow for active pen input events. Since active pens allow for their position to be detected without making contact with the screen, an …

Short-Distance Translocation Of The Northern Pacific Rattlesnake (Crotalus O. Oreganus): Effects On Volume And Neurogenesis In The Cortical Forebrain, Steroid Hormone Concentrations, And Behaviors, Matthew L. Holding

Master's Theses

The hippocampus of birds and mammals has been shown to play a crucial role in spatial memory and navigation. The hippocampus exhibits plasticity in adulthood in response to diverse environmental factors associated with spatial demands placed on an animal. The cortical telencephalon of squamate reptiles has been implicated as a functional homologue to the hippocampus. This study sought to experimentally manipulate the navigational demands placed on free-ranging northern Pacific rattlesnakes (Crotalus o. oreganus) to provide direct evidence of the relationship between spatial demands and neuroplasticity in the cortical telencephalon of the squamate brain. Adult male rattlesnakes were radio-tracked …

Impact Of Exercise On Brain Responses To Visual Food Cues: An Fmri Study, Nero Erezi Evero

Master's Theses

On the basis of a strong body of data, the Institute of Medicine currently recommends at least 60 minutes of exercise per day to prevent body weight gain overtime.  Previous studies have shown that there is no compensatory increase in food intake with this dose of exercise. Ultimately, the brain decides whether to alter food intake.  Surprisingly, no published studies have assessed the impact of exercise on brain activation.  Using functional magnetic resonance imaging (fMRI) and an appetite questionnaire, we investigated the effects of a single bout of aerobic exercise on brain responses to visual food cues and subjective appetite …

Studying Milk Coagulation Kinetics With Laser Scanning Confocal Microscopy, Image Processing, And Computational Modeling, Richard Joseph Hennessy

Master's Theses

The kinetics of milk coagulation are complex and still not well understood. A deeper understanding of coagulation and the impact of the relevant factors would aid in both cheese manufacturing and also in determining the nutritional benefits of dairy products. A method using confocal microscopy was developed to follow the movement of milk fat globules and the formation of a milk protein network during the enzyme-induced coagulation of milk. Image processing methods were then used to quantify the rate of coagulation. It was found that the texture of the protein network is an indicator of the current status of the …

Characterization And Implementation Of A Decellularized Porcine Vessel As A Biologic Scaffold For A Blood Vessel Mimic, Aubrey N. Smith

Master's Theses

Every 34 seconds, someone in the United States suffers from a heart attack.  Most heart attacks are caused by atherosclerotic build up in the coronary arteries, occluding normal blood flow.  Balloon angioplasty procedures in combination with a metal stent often result in successful restoration of normal blood flow.  However, bare metal stents often lead to restenosis and other complications.  To compensate for this problem, industry has created drug-eluting stents to promote healing of the artery wall post stenting.  These stents are continually advancing toward better drug-eluting designs and methods, resulting in a need for fast and reliable pre-clinical testing modalities. …

The Ma-10 Cell Line As A Model Of Insl3 Regulation And Leydig Cell Function, Mary E. Strong

Master's Theses

Leydig cells produce testosterone in response to luteinizing hormone (LH) via the cyclic adenosine monophosphate (cAMP)/protein kinase A pathway. Additionally, these cells are responsible for producing insulin-like peptide 3 (INSL3), a peptide hormone that is essential for testicular descent. The insl3 promoter in Leydig cells can be activated by cAMP through the transcription factor Nur77, which has also been shown to regulate the promoters of the steroidogenic enzymes, cyp17 and 3b-hsd. While the mechanism of LH action on testosterone production is well characterized, the effect of LH on insl3 abundance has yet to be shown directly. The MA-10 …
