Dear St
udent Researchers,


Thank you for cont ri but i ng t o t he
22
nd

Annual Student Research Forum. It is our pleasure to attend
this event and learn of the interesting research our students are doing. One of the most critical goals
of higher education is to encou
rage intellectual inquiry and critical thinking. Research provides
significant hands
-
on experience in these areas as you’ve discovered in your own projects. Whether
you pursue a research
-
related career or not, the skills you have learned in carrying out
your projects
will serve you well.

Research skills are valuable life skills in our increasingly information
-
rich
world.

The ability to define a question,
to
collect and organize information relevant to that question,
and to
evaluate and ultimately use the
new knowledge will be useful in many facets of your lives.


Congratulations on your achievements.

Your project is a testament of your hard work,
determination, perseverance, and commitment, and a monument to the dedication of your faculty
mentors.

We hope
you enjoy this year’s research forum and
wish

you

continued success.


Sincerely,

Dear Judges,


On

behalf of all those involved in organizing and presenting this year’s Student Research Forum,
and on behalf of the students participating in this year’s event, I’d like to thank all of you for giving
so graciously of your time and expertise.


The judges
for this forum come from a wide variety of disciplines and scholarly traditions.

One of
the advantages of an event such as this is the opportunity it provides for students to interact with
faculty and gain valuable feedback on their projects.

Hopefully thi
s experience will also be
beneficial to you by providing you with exposure to the wide range of interests pursued by students
at The University of Memphis, and by giving you a preview of the future of your respective fields
and disciplines.


Again, thanks

to each of you for participating in this year’s Student Research Forum.

Without your
cooperation, support, and enthusiasm
,

our students would miss a wonderful opportunity to interact
with and learn from the highly skilled faculty here at The University of

Memphis.


Sincerely,

The Country i s Gone: Fl annery O'Connor's South i
n
Wise Blood


Elizabeth Allen (English), Presenter


Flannery O’Connor’s
Wise Blood

contains a large amount of cultural and social
commentary. The novel depicts the South in the late 1940s as urban centers grow and rural towns
disappear. Upon returning from

World War II, Hazel Motes discovers that his hometown, Eastrod,
Tennessee, has vanished. He is then forced to live in the city. O’Connor presents a displaced rural
character in a chaotic, media
-
saturated urban environment. Throughout the novel, O’Connor
p
rovides her reader with images of a transformed Southern landscape and culture as rural space
evaporates and urban space transforms the region.



Strengthening Communities Initiative: Old Town Millington


Holly Hendrix (Architecture), Presenter


The City o
f Millington has recently become involved in a situation forcing citizens to
patronize either local historic businesses or large corporations on bordering highways. This has led
to vacancy and disrepair in the Old Town historic area, but Millington has beg
un to put faith in the
Main Street revitalization model. Will this model be applicable to Millington or will its re
-
invention
be necessary? Our goal is to identify commonalities between Old Town Millington and cities of
similar size, economic situation, an
d demographics that have implemented this model while
proposing methods of its reinterpretation for the needs of Millington.

thoughts and behaviors. However, research shows that only one in four college students are actually
knowledgeable about suicide prevention resources. This study investigates whe
ther knowledge
about suicide prevention resources, especially campus

approach,
first,
we estimate t
he effects of migration
due to h
urricane Katrina on crime rates across the United States between 2003 and 2007. To
account for possible endogeneity between the socio
-
economic characteristics of a host

city and
evacuees, we instrument the number of evacuees going to a certain metropolitan area by
its

distance

to New Orleans, LA. The results show
more than
a
13

percent increase in murder and non
-
negligent
manslaughter,
almost

a
3 perc
ent increase in robb
ery, and
a
4.1

percent increase in motor vehicle
theft.

Secondly, we examine Houston, home for a large number of comparatively more
disadvantaged evacuees, and find dramatic increases in murder (27 percent) and aggravated assault
(28 percent) coupled with
increases in illegal possession of weapons (32 percent) and arson (41
percent)
in areas lived by evacuees. O
verall, Katrina is associated with a 4 percent increase in
violent crime or 8 additional offenses per month. However, there
is no information on whe
ther the
crimes were committed by evacuees, or we
re triggered by their presence.

remitting multiple sclerosis (RRMS) is a chronic disease affecting about 400,000
people in the US. Interferon betas are first line agents used to treat RRMS. Objective: The s
tudy
explored the impact of patient adherence to interferon
-
beta therapy on MS relapse rates and
healthcare resource utilization. Methods: A non
-
experimental, retrospective cohort design was used.
The sample population (N=1,606) was followed for three year
s. Results: Adherent patients tended
to have a lower risk of relapses, emergency room visits, and inpatient admissions over 3 years than
non
-
adherent patients. Conclusion: Opportunities exist to reduce healthcare resource utilization and
costs among RRMS p
atients.

The method ensued was a series of qualitative interviews
spanning five weeks with six participants.

As a result of this qualitative study, four themes are
relative to the review of literature: (1) understanding and knowing; (2) confidence; (3) convenie

and
(4) recollection.

Two areas of discussion emerged regarding the results

the results as relevant
to the literature and the results as relevant to the retention of adult learners in the community college
classroom.




Psychosocial Model to Explore G

Caroline Hart (Psychology), Presenter


This study focused on antecedents to school delinquency while giving special attention to
factors derived from Hirschi’s (1969) social bond theory and to gender differences. Pa
th model
analyses highlighted stronger bond to school as the most influential factor in combating school
delinquency for both genders. For boys, the second most influential variable was higher
socioeconomic status (SES) followed by higher parental involvem
ent, greater involvement, lower
commitment to sport activities, stronger beliefs and greater commitment to non
-
sport activities. For
girls, the second most influential variable was stronger parental involvement followed by higher
SES, greater commitment to

non

PMMA Bone Cement Formulation


Jennifer Brooks (Biomedical Engineering), Presenter


When a physician
-
directed antibiotic
-
loaded polymethylmethacrylate bone cement
formulation is used in total hip and knee arthropl
asties, current practice in the United States can
involve an arbitrary choice of the antibiotic loading.

This project defines an approach to developing
a rational method for determining this loading.

Daptomycin, a cyclic lipopeptide antibacterial agent
act
ive against Gram
-
positive bacteria, was mixed into bone cement at various concentrations and
made into test specimens.

Fatigue, elution behavior, and activity testing were performed.

Based on
this data, a nonlinear optimization determined that 1.36 grams o
f daptomycin blended with 40
grams of cement powder produces an optimum blend.

Efficacy of Fr

Paul Young June Kim (Electrical and Computer Engineering), Presenter


In this work, we propose a novel fractal
-
based technique to analyze pseudo 2D
representation of 1D retinal nerve fiber layer (RNFL) thi
ckness measurement data vector set for
early detection of glaucoma. In our proposed technique, we first convert the 1D RNFL data vector
sets into pseudo 2D images and then exploit 2D fractal analysis (FA) technique to obtain the
representative features. Th
ese 2D fractal
-
based features are further processed using principal
component analysis (PCA) and the final classification between normal and glaucomatous eyes is
obtained using Fischer’s linear discriminant analysis (LDA). An independent dataset is used fo
r
training and testing the classifier. The technique is used on randomly selected GDx variable corneal
compensator (VCC) eye data from 227 study participants (116 patients with glaucoma and 111
patients with healthy eyes). We compute sensitivity, specifici
ty and area under receiver operating
curve (AUROC) for statistical performance comparison with other known techniques. Our
classification performance shows that fractal
-
based technique is superior to the standard machine
classifier Nerve Fiber Indicator (N
FI).

application. Our goals were to assess the quality of the microchannels and evaluate their usage for
chemical sensing with an optical detector. Results indicate the channels lack reproducibility and

Duong T. Nguyen (Biomedical Engineering), Presenter


Bone scaffolds serve as a temporary three

dimensional (3D) environment a
nd template for
bone cell growth and bone formation. Scaffold designs incorporate essential biological and
biomechanical characteristics similar to that of bone for gradual integration and degradation. The
aim of this study is to characterize the change in

compressive modulus of a novel composite
chitosan and calcium phosphate scaffold during enzymatic degradation for 21 days. Two types of
scaffolds were fabricated from air
-
dried microspheres and lyophilized microspheres. For the
combination scaffolds, line
ar regression showed increase degradation correlating to decreased
compressive modulus. The air
-
dried microsphere scaffolds had no significant loss in compressive
modulus with increased degradation.

women continued their struggle for
recognition in the public realm of American society. No longer willing to allow m

represent the women of that era who found their voices and raised them to expand the authority,
credibility, and acceptance of women in the publ

Their significant though unexplored
discourse remains as a rich area of study for the field of rhetoric.

Amanda Gresens, Jennifer Jackson,

Ashley Olberding (Communication), Presenters



Much of women’s entrance into the public sphere revolves around activism in the suffrage
movement.

Often forgotten, however, are other issues of women’s public discourse.

Margaret
Higgins

Sanger, advocate for birth control rights
;

Charlotte Perkins Gilman
,

author of “The Yellow
Wallpaper
;
” Eleanor Roosevelt, first lady and political activist
;

and Dorothy Day, peace activist and
founder of the Catholic Worker Movement
;

were women who worked

outside suffrage striving to
effect societal and political change.

Each of these figures contributed to American women’s
rhetorical tradition and are worthy of recognition and further study.



Women’s Voices in an Electronic Age


Charlotte Nau, Melody Leh
n, Meagan Elam, Karen Schiefer,

and Adam Johnson (Communication), Presenters


Without question, the advent of radio and television has enabled women to participate more
fully in public life and to communicate more effectively with the masses. Bringing tog
ether diverse
women

a first lady, an activist, a politician, a writer, and an entertainer

this project explores the
various ways women have used the media to create and share messages personal, political, and
sometimes both. In doing so, we will consider i
mportant features of their discourse, including the
establishment of credibility, rhetorical style, the nature of arguments, delivery, and how and why
these discourses fit into a larger women’s oratorical tradition.



From Personal Experiences to Political

Platforms


Michele Scott, Lauren Prather, Staci Thomasson, and

Katrina LeVine (Communication), Presenters


Our project

involves the combined efforts of both a graduate student and three
undergraduate students. Specifically, Sojourner Truth, Angelina Grim
ke, Elizabeth Cady Stanton,
and Victoria Claflin Woodhull will be examined.

And, although the vast differences in both the
rhetorical styles and personal life experiences of these women are undeniable, one key factor ties
these pioneers of women’s rhetoric

together: the use of such personal experiences to create a most
salient form of ethos in their speaking.

Criterion Validity of Accelerometer

Derived Peak Power

Obtained During Loaded J
ump Squats


Christina R. Feldmann (Health and Sport Sciences), Presenter


This study was designed to determine the reliability, precision, and criterion validity of an
accelerometer device for assessing peak power. Fifty
-
two subjects performed countermovem
ent and
static jump squats at 20, 30, and 40% of their back squat 1RM. The criterion measure was acquired
from direct measures of velocity and force. Predicted peak power was obtained using an
accelerometer. Stability reliability was high (r
>

0.76), preci
sion was good (CV
<

14.5%), and
criterion validity was high (r
>

0.73) in most conditions. Therefore, the accelerometer appears to be
a convenient alternative for measuring peak power in most loaded jump squats.

On the Tradeoffs of FIB Aggregation Algorithms


Yaoqing Liu (Computer Science), Presenter


The global routing table has been increasing rapidly, outpacing the upgrad
e cycle of router
hardware. Recently aggregating the size of Forwarding Information Base (FIB) emerges as a
promising solution since it reduces FIB size significantly in the short term as well as be compatible
with any long
-
term architectural solutions. In

this paper, we evaluate and compare several FIB
aggregation algorithms using recent routing tables from RouteViews. The results highlight the fact
that any FIB aggregation algorithm has to make a tradeoff among three factors: table size,
computation time,

and extra routable space. The quantification of pros and cons of different
algorithms will help operators choose FIB aggregation algorithms best suited for their networks.

Mahbubur Rahman a

Behavioral scientists are often interested to find relationship between stress and different
contexts. Two such related contexts are smoking and having conversations. For example, people
may smoke due to me
ntal stress. Again, conversation can also affect the stress level. We, in this
work, aim to infer these contexts. We develop a conversation and smoking detection module as a
part of a stress inferencing application implemented in Android G
-
1 cell phone. Sp
eaking and
smoking has significant effect on the respiration. We use a chest band where
a
respiration sensor is
placed to capture the respiration signal. It measures the lung volume. We collect respiration signal

from different subjects in natural environ

Impact of the Percepti on of Mascul ini ty on Acceptance of

Homosexual i ty Among Afri can Ameri can Mal es


Al i sha M. Harvey (
Co
unseling Educational Psychology and Research
), Presenter


In the African

American community, especially, the dichotomy between masculinity and
homosexuality seems especially troublesome. Many African

American homosexuals have been
burdened with trying to m
aintain their status as masculine while acknowledging their sexuality. The
coveted status of masculine, which historically has been taken from them, has continued to
psychologically emasculate the African

American male in American society. Because of these

deep
-
rooted issues, and in an attempt to establish their manhood in society, African

American males have
been statistically more likely to conform to a more traditional interpretation of masculinity. This
outlook undoubtedly influences their views on perv
ersions and especially homosexuality.



Infant Mortality and Racial Residential Segregation: an Odds Ratio Analysis


Rachel Kannady (Sociology), Presenter


Currently in the United States there is a major health care controversy.

The lack of
comprehensive h
ealth care directly influences infant mortality.

It would follow that as racial
residential segregation in standard metropolitan statistical areas increases infant mortality in race
minorities would increase as well.

U
.
S
.

black infant mortality has consist
ently been twice, or more,
than that of whites and this disparity may be due, in part, to racial residential segregation patterns in
the U.S.

This study evaluates racial residential segregation using the Cutler/Glaeser/Vigdor
segregation data dissimilarity

index from 2000.

Using period and cohort data from 1996
-
2005
linked birth/infant death data compiled by the National Center of Health Statistics of Centers for
Disease Control and Prevention as part of the National Vital Statistics System, this data will
be
evaluated based on infants being born in the United States only.

Kati e Lang (Psychol ogy), Presenter


Dri nki ng among col l ege st udent s i s a prevai l i ng concern t hat resul t s i n seri ous
consequences. Despi t e t he dangerous out comes, Park (2004) found t hat 90% of part i ci pant
s
consumed alcohol in the past month, suggesting that there may also be positive effects of drinking
(PED; Murphy et al.
,

2005). The present study looked at the frequency of PED in a sample of 207
college drinkers from the University of Memphis to assess i
f they are a predicting factor of risky
drinking. The most common identified positive effects was telling a “funny joke/story” and weekly
drinking significantly predicted PED (
t

= 7.47;
p

< .001).

Houston Hagewood (Psychology), Presenters


This study assessed the role of avoidant sympt
oms as a mediator between negative network
orientation and depression. Model 1: NOS was significantly associated with greater CAPS AVD.
CAPS AVD demonstrated a strong association with higher BDI
-
II scores independent of NOS. The
product of these associatio
ns was a significant indirect relationship between the NOS and BDI
-

through CAPS AVD. Model 2: NOS was associated with greater IES

Female, CD
-
1 mice were exposed to 0, 2, 20, or 200 µg/kg/day Bisphenol
-
A (BPA) or 5
µg/kg/day ethinyl estradiol (EE2) throughout gestation and lactation.
The behavioral activating
effects of acute and chronic cocaine were assessed in one male and female
/litter during adolescence.
No differences in the motor
-
stimulating effects of acute cocaine were found among the exposure
groups. Control mice did not exhibit cocaine behavioral sensitization to repeated dosing, and
exposure to BPA or EE2 did not alter t
his outcome. Overall, these results indicate developmental
BPA
-
exposure does not alter the motor
