Boy Student/Girl Student: Exploring Early Childhood Teacher Perceptions Of Gender And Their Influence On Children's Learning, Elizabeth Oliver

HIM 1990-2015

Brain development in children has always been fascinating to me; it was the reason I chose to major in Early Childhood Education. I have often wondered how the expectations and behavior of parents and teachers affect young children academically. Specifically, how do early gender messages from adults, peers, and the popular media have a powerful impact on the development of young brains? The professional responsibility of all educators is to help every child reach their full potential. This thesis explored the potential impact early childhood educators have in developing and reinforcing stereotypes that can affect children academically by surveying teachers …

At The Frontlines Of The Kulturkampf: Social Policy Positions Of Undergraduate Students At A Large University In The Southeastern United States, Julio Montanez

HIM 1990-2015

Social policy concerns groups. Specifically, social policies have been implemented as a means to affect the well-being of sexual and gender minorities, including areas such as health, employment, violence, and many others. Undergraduate student opinions on such policies are an understudied area of survey research. Possible correlates of support for such policy areas include, but are not limited to, sexual prejudice, attributions, increased contact with the minority group, gender, Para-social contact, and many others. This research administered a 55-item survey to undergraduate students at the University of Central Florida. With a sample of 210 individuals, this study aimed to answer …

The Effects Of Stress On Distance Perception, Monica Rosen

HIM 1990-2015

Although there has been a great deal of research on binocular distance perception (Foley, 1980; Gogel, 1977), a number of questions remain unexplored. One such question involves how our ability to perceive distances is influenced by fitness and stress (internal and external). Previous research has shown that kinesthetic stress (via backpack weight) influences a person’s ability to accurately guess distances (Proffitt, Bhalla, Gossweiler, & Midgett, 2003). This research did not only attempt to replicate previous work, but also extend it by exploring potential interactions between fitness level and mental stress on distance perception, a combination that is often encountered by …

Precision Measurement Of The Lambda_B Baryon Lifetime, Bilas Kanti Pal

Dissertations - ALL

The ratio of the Lambda_b baryon lifetime to that of the B0 meson is measured using data corresponding to an integrated luminosity of 3.0 /fb collected with the LHCb detector using pp collisions at the LHC. The Lambda_b baryon is observed in the decay mode Lambda_b ->J/psi p K-, while the B0 meson decay used is the well known B0->J/psi pi+ K- mode, where the pi+K- mass is consistent with that of the K*0(892) meson. The ratio of lifetimes is measured to be 0.971+/-0.007+/-0.005, in agreement with theoretical expectations based on the heavy quark expansion. Using previous determinations …

Retrieval Of Free Space Radiation Patterns Through Measured Data In A Non-Anechoic Environment, Weixin Zhao

Dissertations - ALL

Antenna pattern measurements are usually carried out in an anechoic chamber. However, a good anechoic chamber is very expensive to construct. Previous research has attempted to compensate for the effects of extraneous fields measured in a non-anechoic environment to obtain a free space pattern that would be measured in an anechoic chamber. Existing compensation techniques are like the Test Zone Field compensation method, the Fast-Fourier-Transform-based method, the Matrix Pencil method, and the Antenna Pattern Comparison technique.

This work illustrates and extends a deconvolution methodology which allows the antenna measurement under a non-anechoic test environment and retrieves the free space radiation …

Experimental Investigation Of The Active Flow Control On A Two-Dimensional Wind Turbine Airfoil, Guannan Wang

Dissertations - ALL

Wind turbine blades experience unsteady aerodynamic loading under various off-design conditions. The fatigue loading reduces the operational time of the wind turbine hence leads to an increase in the Cost of Energy (CoE) of the wind power. In this study, active flow control with unsteady blowing actuators was applied to a two-dimensional wind turbine airfoil to alleviate the unsteady aerodynamic loading and improve the aerodynamic performance, particularly under large scale freestream disturbances. A low speed, open jet aeroacoustic wind tunnel was designed and constructed based on an existing anechoic chamber for this investigation. A theoretical analysis based on a Blade …

Recombinant Expression, Purification, And Characterization Of An Hiv-1 Tat-Human Cyclin T1 Chimera, Collin Lesley Fischer

Dissertations - ALL

Efficient transcription of the human immunodeficiency virus type 1 (HIV-1) requires the interaction of the viral protein Tat with the trans-activation response (TAR) stem-loop of the long-terminal repeat (LTR) portion of nascent viral RNA. The production of viable transcripts is enhanced dramatically by the interaction of HIV-1 Tat with the host protein human Cyclin T1. Interaction with hCycT1 remodels Tat protein contributing a single cysteine residue that is critical to the formation of the second of two zinc fingers (Zn2). Here we suggest that it is the presence of this critical cysteine residue and not the presence of arginine residues …

Barriers To Membership In The American Dental Hygienists’ Association In The State Of Georgia, Brandy Henderson

Electronic Theses and Dissertations

Professional associations must have a significant level of membership to be effective. Georgia membership is increasingly low; therefore, ADHA cannot represent dental hygienists’ interests. This study determined factors that caused dental hygienists to continue to forgo membership in the ADHA. Several theoretical views of professional membership were considered. The sample was acquired from an unbiased systematic sampling of 50% (3,270) of registered dental hygienists and a convenience sampling of ADHA nonmembers at 2 continuing education seminars in Georgia. Data collection procedures included an electronic cover letter, consent form, and survey via Survey Monkey or hard copies for seminars. Three hundred …

Comparing Resiliency In Early And Late-Life Bereavement., Janna Lynn Imel

College of Arts & Sciences Senior Theses

Bereavement is the state of dealing with a significant loss (M.S. Stroebe, Hansson, Schut, & Stroebe, 2008). Although evidence suggests that there are differences in the bereavement and coping styles of older and younger adults, few studies have been done focusing solely on the differences. The lack of research on this topic merits further study. The purpose of this project was to examine the differences in negative emotions, affective complexity, and repressive coping, between bereaved younger and older adults. We hypothesized that bereaved older adults would report fewer negative emotions, have greater emotional complexity, and use repressive coping more than …

Symptoms In Early And Long-Term Breast Cancer Survivors Who Have Completed Primary Therapy, Faith Strunk

Dissertations and Theses (Open Access)

Background

Many breast cancer survivors continue to have single or multiple symptoms after they have completed primary cancer therapy. The quantifiable, subjective experience of multiple symptoms and their impact is defined as symptom burden. Previous research has focused on symptoms during primary therapy or shortly after completion of treatment.

Objectives

Our study objectives were to determine whether symptom burden differed according to survivor status (early as opposed to long-term survival) and/or use of endocrine or hormonal adjuvant therapy. We hypothesized that there would be no difference in the symptoms expressed among early- and long-term survivors.

Methods

In this cross-sectional study, …

5-Azido-2-Aminopyridine, A New Nitrene/Nitrenium Ion Photoaffinity Labeling Agent That Exhibits Reversible Intersystem Crossing Between Singlet And Triplet Nitrenes, Maxim S. Panov, Valentyna D. Voskresenska, Mikhail N. Ryazantsev, Alexander N. Tarnovsky, R. Marshall Wilson

Chemistry Faculty Publications

The photochemistry of a new photoaffinity labeling (PAL) agent, 5-azido-2-(N,N-diethylamino)pyridine, was studied in aprotic and protic solvents using femtosecond-to-microsecond transient absorption and product analysis, in conjunction with ab initio multiconfigurational and multireference quantum chemical calculations. The excited singlet SI state is spectroscopically dark, whereas photoexcitation to higher-lying singlet excited S-2 and S-3 states drives the photochemical reaction toward a barrierless ultrafast relaxation path via two conical intersections to S-1, where N-2 elimination leads to the formation of the closed-shell singlet nitrene. The singlet nitrene undergoes intersystem crossing (ISC) to the triplet nitrene in aprotic and protic solvents as well as …

When Isaac Was A Priest, John W. Fadden

Verbum

In lieu of an abstract, below is the essay's first paragraph.

"On his deathbed, the patriarch Isaac received the important men from the city to talk to him. Among these men was an unnamed priest of God who requested Isaac to tell him a word (T. Isaac 4.8). In this moment, the Testament of Isaac¹¹ depicts Isaac as a priestly authority who is able to instruct priests. If you have not read ancient narratives in which Isaac plays a role, but have only read Genesis, you might be confused: Why does it represent Isaac in this manner? Was …
