Feedback-Related Neuronal Processing During Motor Learning
Get PDFMotor learning has been widely examined using electroencephalography (EEG) to record event related potentials (ERP). ERPs occur in response to given stimuli and represent underlying neural processes that are either modifying or being modified by motor learning. This study seeks to examine how movement feedback changes neural activity (i.e. ERPs) in the motor cortex, and more specifically, if feedback-related neuronal activity is modified by motor learning and visual feedback. A novel visuomotor rotation task was employed in which participants adapted their movement to a 30- degree counter-clockwise rotation. Feedback was given through the presence or absence of the trajectory line of participants’ movement. Surface EEG was utilized to record cortical neural activity throughout the motor task. Event related potentials were obtained at electrodes Cz and FCz. Behavioral data shows that participants successfully learned the visuomotor task over time. There was a significant difference in amplitude of ERPs between conditions where visual feedback was present and conditions where visual feedback was absent. However, the average ERPs amplitudes were not changed by learning. These results suggest that feedback-related neuronal activity contributes to processing visual sensory feedback, but not motor adaptation, during the task
A Comprehensive Examination of University of Mississippi Early Entry Students’ Perceptions of Mental Illness
Get PDFMental disorders affect nearly 1 in 5 adults in the United States in a given year, and that number is steadily increasing. Pharmacists, being some of the most accessible and frequently contacted health care professionals, must be prepared to provide support for these patients. They can play a key role in whether or not there is a positive patient outcome. Education can play a role in pharmacists’ comfort with and knowledge of mental illness. The primary objective of this study was to determine if University of
Mississippi early-entry pharmacy students’ mental illness knowledge, familiarity, and acceptable social distance affected their attitude towards mental illness patients. The secondary objectives of this study were to test for differences in knowledge, social distance, and attitude towards mental illness based on gender, year in school, work experience in a pharmacy, and previous courses addressing mental illness. The study employed a descriptive, cross-sectional survey to collect study data from 95 early-entry pharmacy students. The respondents reported their lifetime knowledge of mental illness
just above average. A majority of the respondents reported their familiarity with mental illness on the lower extremity of the spectrum. Most respondents had observed a person, in passing, who they believed to have a severe mental illness but had never lived with a person with a mental illness. The respondents were more willing to have some social distance between someone with a mental illness. They were more willing to work alongside that person but less willing to share an apartment with that person. Overall, the respondents had a positive attitude towards individuals with mental illness. However, there was still a slight negative stigma. This could be improved by adding more courses that address mental illness into the curriculum
Archaeological Investigations at Rowan Oak: Searching for Evidence of Antebellum Slavery
Get PDFAlthough best-known as the home of William Faulkner, Rowan Oak and a number of associated outbuildings were built by Robert Sheegog, a wealthy individual who owned multiple plantations and dozens of slaves. Sheegog held seven to nine slaves at Rowan Oak, renting some out to the University of Mississippi for labor-intensive tasks such as constructing the Lyceum and other campus buildings. Although it is known that enslaved individuals lived and worked on the property of Rowan Oak, the location of their housing remains a mystery. Through the use of archaeological survey methods, structural evidence beyond the extant buildings has been uncovered
[FEMALE]: A Collection of Profiles Featuring Influential, Inspiring, Modern American Women Who Have Made History
Get PDF[FEMALE] is a collection of profiles that feature the stories of some of the most influential and inspiring modern American women and how they have influenced the world. The profiles look into the lives and careers of female athletes, entrepreneurs, political figures and entertainers who are currently alive in 2019. Each profile includes dialogue from recorded interviews with the featured women.
The idea for this project came from wanting to learn more about the successful, influential role models in my life. To learn about the hardships and odds they overcame in order to achieve their dreams and become the women they are today. I chose a diverse range of women to feature in hopes that anyone that reads this collection would be able to identify a woman they can emulate. I believe in women and I hope these profiles serve as a reminder that women are capable of changing the world, one story at a time
Economic Advancement Across the European Playing Field
Get PDFThis project seeks to examine the relationship between economic history, soccer, and economic institutions in countries who have attained varying levels of success on the soccer field and economically. The work of several influential scholars in recent decades has drawn attention to the need for a shift in the goal for economic achievement from industrialization to institutional effectiveness. This study develops a model to further understand the relationship between economic achievement and soccer success. It then includes case studies of three countries from the model in order to further understand the impact of the institutions that have a significant presence in the model’s most successful country. This study finds a noteworthy correlation between soccer performance and national GDP and population. Furthermore, case studies of Germany, Croatia, and Serbia reaffirm the importance of economic institutions and their contribution to economic success and soccer success
Frames, Fallacies, and the Market for Lemons
Get PDFThe purpose of this thesis is to illustrate the impact of an “endowment frame” on
risk behavior in games of asymmetric information. Akerlof’s (1970) description of a
“market for lemons” led to the creation of a modified screening game into which the
endowment frame could be placed. The game was subsequently computerized and
administered to 18 test subjects in the Mississippi Experimental Research Laboratory. At
the beginning of the experiment, test subjects were randomly assigned to either a control
or treatment group. Each participant played 20 rounds of the game and was compensated
based on his or her performance. The term “endowment frame” refers to the $0.50
endowment that was granted to treatment group participants at the beginning of each
round. Despite the presence of this endowment, the payoff structure was designed so that
the expected value of both bid types, high and low, were the same for both experimental
conditions. Therefore, in theory, both groups should have produced the same bid
selection profiles. However, empirically the treatment group subjects were more likely to
select the lower, “riskier” bid. This is consistent with the presence of an endowment

6th-12th grade math teachers and their experiences with the Mississippi College- and Career-Readiness Standards
Get PDFThis thesis identifies and describes 6th-12th grade math teachers and their experiences with the Mississippi College- and Career- Readiness Standards. There are two parts to this thesis: 1) a survey distributed to public school math teachers across the state and 2) the written thesis. In my thesis, I craft teacher narratives from the quantitative and qualitative results of the survey. Listening to the teachers’ narratives provides beneficial insights to the implementation of the MCCRS at the classroom level. Teachers have many different experiences. My thesis offers policy recommendations, based on the teacher narratives, to three levels of education: teachers, schools and school districts, and policy makers. It is evident that teachers’ experiences are essential in improving our education. I hope this thesis may serve as a bridge between all levels and actors of public education in Mississippi
El hip-hop cubano: An Agent of Social and Political Change in Cuba?
Get PDFCuba experienced two distinct periods during which Afro-Cubans encountered various constraints and opportunities. During the Revolutionary Period, the Cuban government outlawed all forms of discrimination and created many opportunities for Afro-Cubans to participate in society. However, these new opportunities came with the
price of outlawing discussion of racial discrimination and political and social organization along racial lines. Afro-Cubans who still experienced racial inequality faced
the threat of political imprisonment if they spoke out against discrimination. In contrast, during the Special Period, Cuban experienced a devastating economic collapse in 1991. Government policies created in response to the collapse removed many of the opportunities for equality that the Cuban Revolution created, and as a result, many Afro
Cubans faced greater levels of inequality. Due to new policies allowing for greater artistic expression, Afro-Cubans, inspired by the American genre hip-hop, created a Cuban hip-hop genre of their own. Cuban rappers used hip-hop to form a movement known as The Cuban Hip-Hop Movement to speak about racial inequality, poverty, and socioeconomic
issues and to bring racial discrimination to the political discussion. This thesis presents the contrast between the Revolutionary Period and the Special Period and the opportunity or lack thereof to influence political discourse and policies regarding racial inequality
United States Suicide Analysis: 1999-2016
Get PDFThe purpose of this thesis is to create information visualizations surrounding suicide trends from 1999-2016 in the United States. The original data was obtained from the Centers for Disease Control and Prevention’s Compressed Mortality Database. This database permits users to download several fields of information regarding deaths for the years given. Using this information, many graphs below show trends and patterns for suicide. One notable trend includes the higher proportion of male to female suicides for all categories explored including: age group, race, and metro/nonmetro status. The goal is to bring awareness and understanding surrounding the suicide epidemic in the United States
On a Generalization of Lucas Numbers
Get PDFIn this paper, we consider a generalization of Lucas numbers. Recall that Lucas numbers are the sequence of integers defined by the recurrence relation:
L_n = L_{n−1} + L_{n−2} with the initial conditions L_1 = 1 and L_2 = 3(or L_0 = 1 and L_1 = 3 if the first subscript is zero). That is, the classical Lucas number sequence
is 1, 3, 4, 7, 11, 18, .... The goal of the present paper is to study properties of certain generalizations of the Lucas sequence. In particular, we consider the following
generalizations of the sequence: l_n =
al_{n−1} + l_{n−2} if n is even;
bl_{n−1} + l_{n−2} if n is odd,
for n = 3,4,5,..., where a and b are any nonzero real numbers, with the initial conditions l_0 = 1 and l_1 = 3 (see Section 2.0.1) and l_n = (−1)^nl_{n−1} + l_{n−2} for n = 3, 4, 5, ... with the initial conditions l_1 = 1 and l_2 = 3 (see Section 3.1.2). More precisely, we will determine the generating function and a Binet-like formula for {ln}^∞_{n=0} and demonstrate numerical simulations for {ln^∞_{n=1}, proving some relations using Principle of Mathematical Induction
