A Message from the Graduate Student Council Executive Board

Dear Conference Participants,

Thank you for attending the annual Graduate Student Council Interdisciplinary Research Conference! We
are thrilled to be sharing this event with so many talented members of the university community. This
year over 100 graduate and undergraduate students are participating in twenty panel sessions and nearly
fifty poster presentations. It is our hope that through this conference new connections will be forged that
will result in shared knowledge and collaboration. To that effect, we encourage you to attend as many
presentations and visit as many posters as is possible for your schedule.

As you may well know, the Graduate Student Council provides $250 travel grants to graduate students in
order to present their research at conferences. These grants are distributed on a first-come first-serve basis
throughout the academic year. Last year we gave around 500 grants, providing nearly $125,000 in travel
funding to graduate students at the university. Each graduate student is eligible to receive one grant per
academic year. We are currently in the process of completing our transition to a web-based application
system that will ease the process of applying for these grants. We are thrilled that so many of you who
have received travel grants have decided to share your presentations with the university community by
presenting at today's conference. Those of you who have not received funding, we hope you will apply in
the future and will share your presentations at conferences specific to your field.

We would like to thank the many faculty who are also participating today. Your feedback on student
presentations provides an important professionalization experience. Thank you also to those of you who
are able to stay for lunch to eat with conference participants. Thank you for your concern for graduate
student development and your willingness to extend the learning process outside of the classroom.

Our most heartfelt thanks go to the conference committee, whose dedication, energy and enthusiasm to
planning this event have been particularly impressive. Yingyan Lou controlled the pace of the planning
and took care of numerous small details. Erin Tobin has been involved since the very first meeting and
has handled nearly all contact with participants. Joe Wilson was very helpful in brainstorming and
oversaw the taxing process of assigning papers to panels and Siqian (May) Shen has been primarily in
charge of food. Thank you also to Rajeev Mohata, who handles all details related to the website. You
guys put the "commit" in committee! We can't thank you enough!

Finally, we would like to acknowledge a food scholarship from Classic Fare Catering that has graciously
provided morning refreshments.

Enjoy the conference! And we hope to see many of you presenting again next year!

Latin American History and Culture
Discussants: M. Elizabeth Ginway, Associate
Professor, and Gillian Lord, Assistant Professor,
Department of Spanish and Portuguese Studies,
College of Liberal Arts and Sciences
1 Mariel Boatlift
Jany Martinez andAriel Martinez, Department of
Political Science, College ofLiberal Arts and
Miami is more than a place for tourists to come and
vacation for the summer. It is an area that has
undergone major ethnographic changes in the past
thirty years. It shares local government authority with
Dade County. Miami is one of the major cities that
have suffered through an accelerated transformation
phase because of the rapid influx of Latin refugees.
One of the major changes that have occurred in
Miami is due to "The Mariel boatlift" in 1980.
2 The Cabanagem and the Political Crisis of the
Brazilian Regency
Sarah Kernan, Department of History, College of
Liberal Arts and Sciences
Though it is a particularly important episode in
Brazil's history, few scholars outside of Brazil have
devoted any serious attention to the Cabanagem, a
rebellion in the province of Grio-Pard in Amazonia
from 1835-1841. This is particularly startling, as it
was the most deadly uprising in all of Brazil's history,
with estimates of over 30,000 casualties. Politically,
the Cabanagem affected a larger amount of national
territory than any other uprising, and was a
substantial threat to the Imperial government in Rio
de Janeiro.
3 Cuban Architecture in South Florida
Ariel Martinez andAniel Martinez, Department of
Architecture, College ofArchitecture
Vast scrublands, swamps, and pine flats, southern
Florida remained mostly unpopulated until just over a
hundred years ago when Cuban influence spiked a
boom in the regions population and architectural
richness. The first Cuban exodus occurred at the
onset of the Ten Years War, as Cuba struggled to
gain its independence from Spain. The hundreds of
Cubans that were constantly arriving at Key West
were soon finding jobs in the cigar industry
organized by Don Vicente Martinez Ybor. Five years
after the first exodus, Cubans made up the majority
of the population in Key West. The growing majority
asserted their presence by establishing cultural
landmarks and monuments in south Florida.

Session 3B

Africa Studies
Discussant: Yang Jiao, Department of Anthropology,
College of Liberal Arts and Sciences
1 Chinese Entrepreneurial Safari: The Case in
Yang Jiao, Department ofL 1, 1 ,,.l 'i. '.. ', College
ofLiberal Arts and Sciences
China's increasing economic presence in Africa has
attracted extensive attractions in recent years. A
broad range of issues have been previously studied.
However, in-depth ethnography of multiple
stakeholders and the processes in which they
encounter, cooperate and network in a specific site is
widely felt as the most insufficient and sorely needed.
This paper draws on a pilot fieldwork conducted in
2008 summer to discuss the status quo of the Chinese
investment in the Accra metropolis district and Tema
district of Ghana, and provides a context specific
perspective for our understanding of the current
phenomenon of Chinese investment in Africa.
2 Re-conceptualizing Anthropology's Colonial
Encounter: Max Gluckman's Africa and
British Structural Functionalism
Joseph Feldman, Department of iit.' '.i ...'.,
College ofLiberal Arts and Sciences
This paper examines the theoretical contributions of
Max Gluckman in light of critiques of British
structural functionalism. Contemporary observers
have drawn attention to the relationship between
structural functionalism as a theoretical paradigm and
the colonial context of British anthropologists'
research on African societies in the post-World War
II era. I present Gluckman as an anthropologist of
this period who embraced aspects of structural
functionalism but defied convention by incorporating
the power relations of colonial rule into his analyses
of African societies.

Entomology and Nematology
1 Organic and Inorganic Mulches: Impact on
Soil Inhabiting Pests
Harsimran K. Gill, Department ofEntomology
and Nematology, College ofAgriculture and Life
Mulches have been an important component of pest
management programs. Studies were conducted to
test the hypothesis if mulches have effect on soil

Schedule and Abstracts

organisms. Various organic mulches were evaluated
for their effect on soil inhabiting insects, weeds and
nematodes. Six plastic sheets were also tested against
nematodes and weeds. Sampling was done using
Berlese traps, pitfall traps and wooden boards.
Sunhemp was found to be more resistant to
degradation and effective against insect population
compared to other mulches tested. Also, polydak
plastic did better in terms of durability and
effectiveness against weeds among other plastics. No
significant difference was found in nematode
populations among various plastics.

Operations Research and Network
Discussant: Tathagata D Goswami, Department of
Electrical Engineering, College of Engineering
1 Expectation and Chance-constrained-based
Models and Algorithms for Insuring Critical
Siqian Shen, Department of Industrial and
Systems Engineering, College ofEngineering
We consider a class of two-stage stochastic
optimization problems arising in the protection of
vital arcs in a critical path network, where one must
trade off costs in insuring arcs with expected
penalties from late completion times. We analyze
different penalty function cases, provide various
formulations, and employ RLT to remodel the
problem to be amenable to solution via Benders
decomposition. We also consider a chance-
constrained formulation of the problem, and propose
the solving algorithm. We employ SAA for scenario
generation and demonstrate the computational
efficacy of our approach.
2 Optimum Node Activation for Geographic
Transmissions in Wireless Channels
To triu.,,ti, D Goswami, Department of Electrical
Engineering, College ofEngineering
Wireless communications is often subject to random
channel fluctuations, known as fading. In such a
scenario, geographic transmission strategies often
perform better than conventional routing approach.
But they require additional receiving energy. We
consider the design of optimal distributed strategies
for determining whether a radio should activate to try
to receive a message to enhance the performance of
communication. Our approach offers significant
performance advantages over previous approaches,
and allows us to address related questions involving

transmission rate and power allocation among
transmission and reception.
3 A Robust Approach to Discrete Network
Design with Demand Uncertainty
Yingyan Lou, Department of Civil and Coastal
Engineering, College ofEngineering
This paper considers discrete transportation network
design problem under demand uncertainty. The
future travel demand is assumed to take on nominal
or one of several other values, where the occurrence
probability of each value is unknown. An uncertainty
set is developed to model the random future demand.
The set allows demands for a limited number of
origin-destination pairs to deviate from their nominal
values simultaneously. We formulate the robust
discrete network design problem as a mathematical
program with complementarity constraints and
propose an efficient and effective algorithm for large

Asian Studies
Discussant: Ching-Yu Louisa Chang, Department of
Sociology, College of Liberal Arts and Sciences
1 A New Look at Electoral Reform in Japan:
from 1982 to the 2007 House of Councillors
Alexander Kanrazes, Department ofPolitical
Science, College ofLiberal Arts and Sciences
In light of recent events in Japanese politics,
exploratory research is conducted and a new theory is
presented which suggests that the often overlooked
1982 House of Councillors electoral reform may have
had a significant impact on the balancing of Japan's
party system. By focusing on the 1982 reform, this
paper hopes to present a new perspective through
which future studies of Japan's electoral systems can
take place.
2 Discipline the Ideal Women: The Lived
Experiences of Female Taiwanese Flight
( l,,Ii- Yu Louisa ( I.I, -. Department of
Sociology, College ofLiberal Arts and Sciences
Flight attendant is known to be a glamorous
occupation in Asia. Different from our previous
understandings of the female-dominated jobs, this
occupation has strict criteria on its qualification.
Voices of Asian women engaging in this occupation
are less revealed from their subjective position.
Therefore examining Taiwanese female flight
attendants' lived experiences will bridge the gap in

the current Western literature on the intersections
between gender and work. Informed by the concepts
of doing gender and the emotional labor, this paper
studies contemporary Taiwanese female flight
3 Intermarriage and Ethnicity among the Hui
and Han in Qiaocheng, China
Zhongzhou Cui, Department of i, thp. .-.',
College ofLiberal Arts and Sciences
This paper is to examine intermarriage between the
Hui, the largest Islamic ethnic group in China, and
majority Han in Qiaocheng, a city in northwest Anhui
Province, and how it affects ethnic identity of the Hui.
This paper will examine the factors to influence
Hui's and Han's preference to intermarriage,
including government favorable ethnic policies,
ethnic education, population distribution, economic
conditions, parent's attitudes, religious affiliation,
and natural affection feeling. This paper concludes
that the Hui's ethnicity is deeply influenced through
intermarriage and ethnoreligiosity is not best term to
represent their ethnicity.

Interdisciplinary Studies of Wildlife and
1 Community Forestry in Mesoamerica, from
Mayan forests to Embera's jungles: an
interdisciplinary approach to sustainable
Ricardo Brown-Salazar, School ofNatural
Resources and Environment
Governments in Mesoamerica have made efforts to
increase the number of protected areas, and to
generate policies and strategies that promote
conservation and reforestation. These efforts have
continually failed to stop the deforestation process
when they not include local communities. Guatemala
and Honduras has been implementing successfully
community-based forest management and based on
these models five communities in Darien, Panama are
starting to manage 26,720 ha of tropical forest. An
interdisciplinary analysis of the forestry sector in
Darien is presented.
2 Input Driven Population Synchrony in Lobster
Olfactory System: A Point Process Modeling
II "Memming" Park, Department of Biomedical
Engineering, College ofEngineering
Perception of odor landscape is vital for marine
organisms such as lobsters to locate and track a food

source, or conspecifics. Due to the turbulence, the
spatio-temporal structure of the odor is discontinuous
and intermittent. It has been suggested that lobsters
detect frequency of odor contact to predict the
distance to the odor source. On the other hand,
recently a new type of olfactory sensory neuron is
discovered in lobsters. Using a computational model
based on a modified renewal process, we tested the
hypothesis that the population of these neurons is
sensitive to input stimulation frequencies in order to
sense the distance of the odor source.

1 Calling home in the global village- The use of
language exchange communities in language
Sam Schramski, Department of Geography, Cem
Balcikanli, Center for European Studies, College
ofLiberal Arts and Sciences
In line with current developments in language
learning, multimedia applications provide language
teachers and learners with effective means to make
language acquisition and learning more viable and
more independent (Tschirer 2001, Wolff 1994).
More specifically the language exchange
communities including My Language Exchange,
Mixxer, xLingo, LiveMocha and Worldia provide an
appropriate framework for more authentic and
learning experiences. In this workshop we will
present examples of language exchange communities
and some of best practices employed to faciliate
language acquisition
2 Interrogative Constructions in Kavalan
Dong-Yi Lin, Department of I f,,,, iin,. College
ofLiberal Arts and Sciences
Four types of interrogative constructions are attested
in Kavalan. The first type applies only to oblique-
case-marked nominal wh-words. Secondly, questions
concerning abosolutive wh-words must be formed via
a pseudo-cleft construction. Thirdly, some wh-words
can never stay in-situ but must serve as predicates
directly without pseudo-cleft formation. Finally,
interrogatives like tanian 'where' and quni 'how'
behave as a typical verb. The distinct syntactic
behaviors of Kavalan interrogatives have significant
implications for the typology of question formation in
terms of how and where wh-words can move in the
syntactic derivation cross-linguistically.

3 On the topicality of topical markers
Sean A. Witty, Department of l ,,oi, n,. ...
College ofLiberal Arts and Sciences
One of the most difficult aspects for non-native
speakers of Korean to master is when to mark
subjects I-i/-kal and when to mark them |-(n)eunl.
Korean grammars routinely refer to these morphemes
as "nominative (subject)" and "topical" markers,
respectively; but a ready understanding of the
topicality of the topical marker and the implicature of
the nominative marker is often left assumed by the
learner. This paper examines various proposals for
topic marking in other languages and tests their
appropriateness for Korean.

1 Conveying Distinct Impressions to Different
Audiences Simultaneously: Examining the
Moderators of Success and Confidence in the
Multiple Audience Problem
Austin Lee Nichols, Department ofPsychology,
College ofLiberal Arts and Sciences
At times, people may find themselves in a
challenging self-presentational predicament-
wanting to convey conflicting impressions to
different audiences in the same social situation. To
date, empirical and theoretical work on this "multiple
audience problem" has been limited. In this
presentation, we describe the reactions of both actors
and audience members from multiple audience
situations created with different methodologies such
as in-lab social situations and role-playing scenarios.
In all, this research provides insight that, combined
with past research, offers valuable direction for future
theoretical and empirical considerations of the
multiple-audience problem.

Session 6B
12:50pm-1:40pm Room 285

English Literature and Poetry
Discussant: Marsha Bryant, Associate Professor,
Department of English, College of Liberal Arts and

1 "The Funerall": John Donne's Treatise on
Katherine Ruark, Department ofEnglish, College
ofLiberal Arts and Sciences
"The Funerall" by John Donne seems to address a
fairly common romantic theme: the speaker wishes to
be buried with a lock of his beloved's hair. The lock
of hair takes on a central emblematic role in the
relationship between lovers within the poem, but the
true significance of the lock is much more complex.
By exploring the lock of hair as a symbol using a
combination of metaphors and complementary rhyme
scheme, Donne examines the function and ambiguity
of symbolism in the realms of love, religion, and
2 Arguing for salvation: The use of logic in
Donne's "Holy Sonnets"
Maia Schuster, Department ofEnglish, College of
Liberal Arts and Sciences
Donne uses the 'art' of logic in his "Holy Sonnets" in
order to present an argument in two parts: first the
problem, then the logical solution. Logical reasoning
in Donne's poetry indicates a shift from Catholicism
to Anglicanism, in that he is deciphering religious
ideas on his own rather than waiting for the church
leaders to tell him what to do. However, Donne uses
his own reasoning to conclude that he is forgiven by
God. Therefore, the "Sonnets"' use of logical
reasoning is the key in exhibiting this time of
religious change in England.
3 Donne's Attitudes Towards the Death of a
Katherine Deirdre Holmes, Department of
English, College ofLiberal Arts and Sciences
John Donne is well known for his poetic theory of
love. He believes that lovers are inextricably
connected with one another; each is the other's entire
world. Donne often relates this concept using the
Ptolemaic system of spheres and other elements of
imagery. His most interesting use of these techniques
comes in his description of love which is confronted
with the death of one lover, but the survival of the
other. In "The Feaver" and "The Dissolution,"
Donne relates the grief the survivor feels. Together
these poems form a complete picture of grief; it is felt
as both an overwhelming burden and as a dramatic
loss. The Ptolemaic system of spheres and a
common imagery in the poems support this message.

4 The Borders of Masculinity: Intersections of
space, gender and identity in Chaucer's dream
Christopher Ramos, Department ofEnglish,
College ofLiberal Arts and Sciences
I discuss Chaucer's use of space in his dream visions
to show that he conflates space with gender and
power. I argue that he uses allusions to male Greco-
Roman explorer-conquerors and their female
counterparts, various narrative structures, character
interactions, and various tropes that pose masculinity
as absolute and spatially unbounded, both physically
and epistemologically, against "abject" identities like
femininity and foreignness that are conversely,
bounded objects to the male Subject.

Alcohol, Drugs and Crime in Society
Discussant: Ryan O' Mara, Department of Health
Education and Behavior, College of Health and
Human Performance
1 Exploring the Immigration and Crime Link:
The Case of Chicago Neighborhoods
Zahra Shekarkhar, Department ofSociology,
College ofLiberal Arts and Sciences
This current study attempts to explore the
immigration and crime relationship in one heavily
populated immigrant city, Miami, FL. This work
provides a theoretical framework through which this
relationship can be examined and serves as a guide
for further research in this area. The frameworks
presented here (social disorganization, conflict theory,
labor/economic theory, and assimilation theory) all
try to explain this relationship by moving away from
the idea of immigrants as inherently criminal, but
through social, structural, and economic reasons. This
present research seeks to study the effects of
immigration on overall city crime rates, during the
distinct immigrant waves in the city's history.
2 Field Methodology for Assessing Late-Night
Drinking, Drug Use and Related Risk
Behaviors in College Bar Distracts
Sara Gullet, Department ofFamily, Youth, and
Community Sciences, College ofAgricultural and
Life Sciences, Miranda Tsukamoto and Henry
Lewis, Department of Health Education and
Behavior, College of Health and Human
Alcohol misuse is a common problem in the
American college student population. The most
frequent cases of alcohol consumption take place at
on-premise alcohol establishments where patrons can

obtain and consume alcoholic beverages such as bars,
clubs, and restaurants. Most of the published
researches rely heavily on retrospective, self-report
survey data. Our research adopts field methods,
where data is collected within natural drinking
settings. Field methods minimize the duration of
recall asked of respondents, and corroborate self-
report with biological and observational data.
Between December 2006 and April 2008, our
research team conducted four field studies in the
college bar districts of a campus community located
in the southeastern United States.
3 Examining the Association between Price of
Alcohol and Intoxication among Patrons of a
College Bar District
Ryan O' Mara, Department ofHealth Education
and Behavior, College ofHealth and Human
Performance, Matthew Rossheim, Department of
Economics, College ofBusiness Administration,
Brian Cruddas, Department of Health Science,
College of Public Health and Health Professions
Econometric research has established that decreasing
the price of alcohol is accompanied by an increase in
alcohol consumption and alcohol-related problems in
the general population. This population-level effect
appears to be especially pronounced in young adults
(18-24 years of age). However, the evidence base for
this relationship at the consumer level is not well-
developed at this time. This field study examined the
direct association between cost per gram of alcohol
and breath alcohol concentration (BrAC) among a
sample of patrons exiting college bars.
4 Assessing Compliance with Outdoor Smoke-
Free Policies
Samantha Carino, Department ofBiology,
College ofAgricultural and Life Sciences
Public smoke-free policies can facilitate lasting,
positive changes in health behavior. Assessing
compliance with such polices can present
methodological challenges, resulting in reliance on
self-report data. This study piloted an objective
methodology to evaluate compliance with outdoor
smoke-free policies. Two neighboring college
campuses in Florida were assessed. Campus A
actively enforced its smoking policy whereas
Campus B only passively responded to complaints.
We tested the hypothesis that Campus A would have
fewer violations than Campus B, controlling for
potentially confounding variables.

1 Role of Integrin Mac-1 in Macrophage-
Mediated Inflammatory Response to
Toral Zaveri, Department ofBiomedical
Engineering, College ofEngineering
Upon implantation, biomaterials or wear debris
particles generated in the body are coated with
proteins which spontaneously adsorb from
physiologic fluids. Macrophages interact with
implanted biomaterials and wear particles through
these adsorbed proteins. The integrin family of cell
surface receptors mediates cell adhesion to
biomaterials through adsorbed adhesive proteins.
Integrin binding to biomaterial-adsorbed proteins has
been shown to direct cell function and mediate
ensuing inflammatory responses. Integrins such as
Mac-1 (aM32) present on macrophages direct various
inflammatory processes such as phagocytosis; hence
they serve as therapeutic targets for modulating the
macrophage inflammatory response.
2 Central Administration of Angiotensin 1-7 is
Cerebroprotective in a Rat Model of Ischemic
Adam P. Mecca, Department ofPhysiology and
Functional Genomics, College of Medicine
Recent progress in cardiovascular therapy suggests
that stimulation of Angiotensin Converting Enzyme 2
(ACE2), production of Angiotensin 1-7 (Ang 1-7),
and activation of the Ang 1-7 receptor, Mas, are
viable targets for disease prevention and treatment.
We proposed that central administration of Ang 1-7
via lateral ventricular cannula will provide
cerebroprotection in a rat model of Endothelin-1 (ET-
1)-induced middle cerebral artery occlusion (MCAO).
Ang 1-7 treatment reduced neurological deficits and
infarct size compared to aCSF treatment at 72 h after
MCAO induction. This evidence provides the first
demonstration of the cerebroprotective properties of
Ang 1-7 during ischemic stroke.

3 Comaprison of Reproductive Performance of
Cows Bred by Timed Artificial Insemiantion
or Natural Service
Fabio Lima, Department of Large Animal
Clinical Sciences, College of Veterinary Medicine
The objective was to compare reproductive
performance of lactating dairy cows bred by natural
service (NS) or timed AI (TAI). One thousand and
fifty-five cows were blocked by parity and enrolled
to receive either NS or TAI. In conclusion, we
attribute the greater proportion of pregnant cows
observed in the NS group to a greater opportunity for
breeding to occur compared with the TAI. The PR21
was not different between treatments, indicating that
within each estrous cycle, both breeding systems
responded similarly in obtaining pregnant cows.

1 Internal Harmony: The Dual Personalities of
the Conductor
Phillip J. Klepacki,School of Music, College of
Fine Arts
In her 2006 book, Listening to the Sirens, Judith
Peraino (invoking Magnus Hirschfeld) posits that
homosexuals hold a position of advantage in music,
both as performer and audience. Peraino's reading of
Hirschfeld conflicts with his own claim that
homosexuals are rarely found on the podium, due to
their inability to manage large groups of people. My
paper examines Hirschfeld's claims as they apply to
the conductors Dmitri Mitropoulos and Leonard
Bernstein. My research shows that the crucial
distinction was Mitropoulos's openness about his
homosexuality. I argue that the greatest hindrance to
professional success for homosexual conductors is
not an internal inability to lead, but rather is found
externally, in the performers, managers, and audience.
2 The Autobiographical Aspects of Robert
Schumann's "Davidsbiindler," Op.6
Ling Fung Chan, School of Music, College of
Fine Arts
Davidsbiindler, Op.6 is one of Robert Schumann's
early piano works. It has a strong affiliation with the
ideology of Schumann's "Davidsbund", his partly real,
partly imaginary band of musicians and critics. In
addition, Schumann wrote Davidsbtindler, with the
intention of honoring his future wife Clara Wieck.
Therefore, Davidsbtindler, is highly autobiographical
in nature. To exemplify the autobiographical features,

I first discuss Schumann's troublesome romantic
relationship with Clara. Secondly, I provide an
explanation of the influence of the "Davidsbund" in
this work. Finally, I present all the musical motifs
and other types of symbolism associated with Clara,
which indicate Schumann's love for her in this crucial
example of romanticism.
3 Critical Thinking Inclusion in Music Classes:
Teachers' Self-Reports: An Exploratory
Survey Conducted in Alachua County Public
Lyndel Bailey, School of Music, College ofFine
The purpose of this study was to gain some insight
from music teachers' self-reporting as to the degree
to which they engage students in critical thinking and
to gather data on some of the ways they foster this
important skill. Data were gathered from a sample of
music teachers in the Alachua County public school
system in Florida through an online survey. Analysis
revealed that the majority of the teachers who
participated seem to have an accurate understanding
of what critical thinking basically entails and how it
can be cultivated through activities in the music

1 The EP Elections the Second Order National
Model revisited with evidence from Romania
and Bulgaria
Magda Giurcanu, Department ofPolitical
Science, College ofLiberal Arts and Sciences
This paper complements previous studies on EP
elections in three distinct ways. First, it tests the
second-order model against data from the most recent
elections: the 2007 EP elections in Romania and
Bulgaria. Second, it assesses the findings for Bulgaria
and Bulgaria against data from all post-communist
countries. Furthermore, the study addresses an
alternative explanation for the familiar findings of the
second-order model. It can be argued that politicians
have much lower stakes in European than in national
elections, and this is what leads to the familiar
outcomes of lower popular mobilization and turnout.

2 Venezuela and Alliance Formation with Russia
and China after 2002: A Balance-of-Threat
David Lopez, Department of Political Science,
College ofLiberal Arts and Sciences
Venezuela, under Hugo Chavez, has turned to Russia
and China to formulate a series of strategic
agreements, thus challenging U.S. influence in the
region. This paper analyzes Venezuela's alliance
formation through the lens of the "balance-of-threat"
model developed by Stephen Walt. This study
challenges prevailing notions about C lu\ ci/' foreign
policy. It suggests that Venezuela's alliances are
motivated by its security concerns. The study shows
that Venezuela, by allying with China and Russia, is
displaying a foreign policy consistent with a balance-
of-threat framework.
3 The Institutionalization of Cooperation:
Bicameral Politics and Bipartisanship
Jordan Michael Ragusa, Department of Political
Science, College ofLiberal Arts and Sciences
Congressional conference committees serve a crucial
legislative purpose: to reconcile bicameral
disagreement. The present research offers a
perspective guided by and consistent with this
description. A new theory of conference committee
politics is proposed where the institutionalization of
bicameral cooperation is the central feature. Armed
with an original dataset covering the 107th through
110th Congresses, it is shown that the strategic
selection of conferees advances cooperation, not
partisan outcomes, in conference first and foremost.
Additional tests of the theory reveal that cooperation
at the conference stage produces centrist outcomes.

the optimization models, different cuts are used and
the integer programming models are formed with
proofs. More generally, a method of modeling
different cuts of biclustering into optimization
problems is proposed.

1 Potentials and Limitations of Technology
Business Incubators as a Tool of Local
Economic Development
Yongseok Jang, Department of Urban and
Regional Planning, College ofDesign,
Construction and Planning
Technology business incubators (TBI) have gained a
wide attention as a potential strategy of local
economic development planning that aims to nurture
technology startups as engines of economic
prosperity, due to the popular consensus that the
success of small business requires external help and
the capital market does not provide a patient
investment. However, researchers do not seem to be
conclusive on the effectiveness/efficiency of
government subsidies for TBI programs. Mixed
results from empirical studies raise questions about
the effectiveness of the program. This paper presents
an alternative perspective by reviewing empirical
research with aims to discuss possibilities and
limitations of TBI program and to eventually help
renewal of policy objectives.

study links parental involvement to community
newspaper coverage through communication
infrastructure theory. The researcher created two
Web site prototypes -- one with mostly community-
contributed content, and the other with news
organization-contributed content. Focus groups were
conducted to determine which Web site Anniston
parents found to be most usable, credible, involving,

Performance will be evaluated for two mixture types:
OGFC and dense-graded Superpave mixture.
Performance evaluation will involve the most
advanced laboratory tests and interpretation methods
available to assess asphalt mixture resistance to

developed at the University of Florida.
2 Three-Dimensional Finite Element Modeling
of Tire-Pavement Interaction
Guangming Wang, Department of Civil and
Coastal Engineering, College ofEngineering
A three-dimensional (3-D) tire-pavement interaction
finite element model was developed, calibrated and
validated in this paper. Tire characteristics reported
by tire manufacturers were used to build a 3-D model
using finite element program ADINA. Contact
groups between tire and pavement surfaces were then
created for a complete tire-pavement interaction
model. Tire model properties were calibrated based
on measured load-deflection curve from one radial
truck tire. The model was then validated by
comparing predicted contact stresses with measured
stresses from the actual radial truck tire. This work
appears to indicate that tire characteristics and load-
deflection data reported by tire manufacturers can be
used to develop 3-D models to predict tire-pavement
interface stresses and their effects on pavement

The interaction of waves and sediment bed on muddy
coasts was investigated based on a data set collected
on the Atchafalaya Shelf, Louisiana. Cohesive
sediment discharge into this region is accompanied
by energetic waves during early spring every year. In
February-April 2008, four instrumented platforms
were deployed between 4 and 8 m isobaths. Acoustic
Doppler Current Profilers measured currents and
directional wave motions in the upper water column.
Near bottom velocity profile and suspended sediment
concentration were monitored by backscatter sensors
and Pulse Coherent-Acoustic Doppler Profilers with
high spatial (3 cm) and temporal (2 Hz) resolutions.
Near bed sediments were observed to show a rapid
response to relatively stronger waves.

In partially mixed estuarine systems the along-
channel momentum balance is considered to be
mainly between pressure gradient and friction. In
this study, the contribution of lateral advection to the
momentum balance is investigated by observing the
exchange flow patterns at several transects of
Hampton Roads, Virginia. Both the residual and the
tidal circulation are examined and how they are
influenced by fortnightly variations in tidal forcing.
Their influence on the lateral advection contribution
to the exchange flow dynamics is also investigated.
Furthermore, the effects of salinity stratification,
bathymetry, wind forcing, and channel curvature are
analyzed and how these affect the residual circulation
and the lateral advection contribution.

Wind-Driven Estuary/Ocean Exchange
Jung Woo Lee andArnoldo Valle Levinson,
Department of Civil and Coastal Engineering,
College ofEngineering
Bathymetry effects on the wind driven circulation at
the transition between an idealized estuary and the
adjacent ocean are studied with the Regional Ocean
Modeling System (ROMS). Several case studies are
performed to determine the relative contribution to
the dynamics at an estuarine mouth of each variable
such as freshwater discharge, Coriolis accelerations,
wind stress and direction, tides, and shape of
bathymetry. Results are cast in terms of three non-
dimensional numbers: Wedderburn (W), Kelvin (Ke)
and Ekman (Ek) numbers. Preliminary results show
that lateral advection is important when Ke is large
and Ek is small. Also, the greatest bathymetric effect
is observed when Ek is large, regardless of W.

Variability of the sub-tidal flow through a short inlet
to a subtropical lagoon located at the entrance to St.
Andrew Bay, Florida, is studied using moored and
towed current velocity profiles and hydrographic data.
Towed and hydrographic measurements are captured
over one diurnal tidal cycle to determine the temporal
and spatial change in the flow during February.
Hydrographic profiles over a tidal cycle show that
tidal straining is significant in modifying the density
structure and thus setting up the observed mean flow
within the inlet.

1 Beliefs about Jesus and Generalized Trust
amongst Christians in the United States
Nicholas Vargas, Department ofSociology,
College ofLiberal Arts and Sciences
A majority of recent religious research that has
focused on particular attitudes or behaviors has relied
on variables that measure religious denomination,
strength of affiliation, and religious behaviors as
indicators of religious influence. While valuable, this
research has often ignored the core of what many
believe, help make up religion: particularly, symbols
and beliefs. This article attempts to bring beliefs back
in to the discussion by exploring their association
with generalized trust; an area in which beliefs have
been overlooked. Preliminary OLS regression results

suggest that non-normative beliefs about the divinity
of Jesus amongst Christians are positively associated
with generalized trust, controlling for other religious
measures regarding behavior and belonging.

This literature review addressed older driver gender
comparisons for self-regulation and driving cessation.
We analyzed 25 studies, graded the level of evidence,
and examined gender findings. Studies provided
mainly level III evidence (cross-sectional). Gender
differences included: driving exposure and avoidance,
self-regulation reasons, alternative transportation
dependence, cessation reluctance, and cessation
reasons. Findings led to five evidence-based
recommendations for practice and research.

Dimensions of Story Quality
Jacqueline M. Baron, Department ofPsychology,
College ofLiberal Arts and Sciences
Nearly all humans tell stories. Previous research has
not employed a standard tool for measuring quality
and has not reported whether men and women raters
of different ages judge story quality similarly. The
current study addresses whether dimensions of story
quality represent a unitary index that is consistent
across men and women of different ages. The major
objective of the study is to create a reliable multi-
dimensional measure of story quality. Results from
an Exploratory Factor Analysis showed that
multidimensional story ratings hang together to form
an index of story quality. The Story Quality Index is
a useful new tool for the standard assessment of story
quality across different types of stories and different

6 Combating D6tente: Neoconservatives and the
Domestic Dispute over SALT II, 1977-1980
Roger Carey, Department ofHistory, College of
Liberal Arts and Sciences
We argue that neoconservative opposition was the
primary source of domestic opposition to detente, or
relaxing of tensions, between the United States and
the Soviet Union from 1977 to 1980. The
centerpiece of detente was the Strategic Arms
Limitations Talks (SALT) II, and these negotiations
became a major focus of neoconservative efforts.
Progress on SALT was the central foreign policy
focus throughout the four years of Jimmy Carter's
presidency. The Carter White House viewed
neoconservative opposition as the primary source of
opposition to their SALT II plans. Both support and
opposition to SALT II were shaped by
neoconservative influences.

Effects of Kosovo's 2008 declaration of
independence on Moldovan Nationalism
Scott Feinstein, Department of Political Science,
College ofLiberal Arts and Sciences
In 1992, the Moldovan civil war began as language
policy coupled with ethnic-linguistic and ideological
divides separated the nation. Most recently, Kosovo's
declaration of independence in February of 2008 has
caused a surge in both Moldovan and Transnistrian
nationalism. I intend to show that a) Moldovan
nationalism is reflected in its language policies,
foreign policies, and media, b) Moldovan nationalism
creates legitimacy for the reunification of Moldova, c)
Transnistrian nationalism creates legitimacy for

Transnistrian independence, and d) the world debate
regarding Kosovo's independence stimulates both
Moldovan and Transnistrian nationalism.

students who have learned Mandarin Chinese
(experienced) and who have not (inexperienced). A
Pretest-Training-Posttest paradigm is used in the
study. Software "Real-Time Pitch" that displays pitch
contours in real time helps all learners to compare,

College of Health and Human Performance
Prescription medications are among the most
frequently abused drugs by college students. Yet little
is known about the co-occurrence of alcohol and
prescription drug use particularly in naturalistic
drinking environments. This field study assessed
exiting bar patrons to determine whether prescription
drug use is associated with (1) increased alcohol
intoxication when exiting a bar at night and (2)
alcohol use disorders. In the college student
population, non-medical use of prescription drugs
may be associated with an elevated risk for alcohol
use disorders, including alcohol dependence. College
health services should assess the non-medical use of
prescription drugs when screening students for
alcohol problems.

students that potentially exacerbates the harmful
consequences of alcohol misuse. However, research
has not assessed the event-specific relations between
alcohol intoxication and drinking alcohol mixed with
energy drinks (or AmED). This exploratory field
investigation sought to evaluate the effect of energy
drink consumption on the intoxication levels of
patrons in a college bar district located in Florida.

Suicide is the 3rd leading cause of death in those
aged 15 to 24 making it a critical issue to address
when working with college students. This study was
designed to understand the relationship between
attachment patterns within close friendships and a
person's reason to live. College students are
transitioning from depending on their parents for a
sense of security to forming attachments to peers as
well as emotional autonomy, The results will be
important to the helping professionals who work with
college students. This study is currently in the data
collection stage.

correlated with unhealthy methods of weight loss.
Girls who used unhealthy weight loss methods were
more likely to initiate cigarette use, instead of just
thinking about. This study was conducted to shed
new light on this behavior among adolescents and
better understand the relation between body image,
diet, and smoking for females. These preliminary
results show a link between body image, weight loss
and tobacco use.

The goals of the current study are to: (a) obtain
descriptive data on self-efficacy, asthma
responsibility, and QOL in a sample of youth with
asthma; (b) examine the relation between family
division of responsibility for asthma management and
perceived self-efficacy; and (c) evaluate self-efficacy

predictors of QOL. An empirical study with 49
patients suggests that, inconsistent with previous
research, there was no relationship between family
division of responsibility for asthma management and
self-efficacy in either parent or child reports.

determinants of unhealthy weight loss practices
among high school students. These findings suggest
female and overweight students had higher risk of
unhealthy weight loss than male and normal weight
students. The participation in exercise, eating fruit
and vegetable regularly, and sleep more than 8 hours
per day can lead youth away from unhealthy weight
loss practices.

Synchronous brain activity plays a major role in
attention, learning, and memory. Studies in rats
characterized Spontaneous frequency bursts (SFBs),
a biomarker of transient, long-range coherence
among brain areas, seen in states of moderately low
brain complexity, across the extended olfactory
circuit. This study demonstrates the occurrence of
SFBs in normal adult mice and juveniles and is
comparing young htau Alzheimer's mice and controls.
The SFB metric may suggest early reductions in

long-range coherence, prior to prevalent tau
pathology in the neocortex and hippocampus.

subjects (age = 31.5 6.4 yrs), who were recreational
and/or habitual ST users were given a 2.5-gram oral
dose of ST after baseline measurements were
recorded. Measurements were taken at 10 min
intervals and obtained in triplicate, non-invasively
using radial artery applanation tonometry. One time
use of ST results in transient significant increases in
central pressures, heart rate, augmentation index, and
wasted left ventricular energy.

wasted pressure energy (E \\ is the portion of the
MVO2 curve attributed to amplitude (RWA) and
duration (RWD) of wave reflection, and can be
interpreted as the excess of energy expended by the
LV. High-fidelity radial artery pressure waveforms

patients (age 659 yrs) with refractory angina taking
two or more anti-anginal drugs (RAP) and 36 treated
hypertensive patients (CON). LVEw was higher in
RAP than CON (30531878 vs. 1457896 dyne*cm-

acupuncture (AC) and electro-acupuncture (EA) at
LI4, LI11, and GV14 on humoral and cellular
immune responses. An in vitro TNF-a production of

equine heparinized-blood stimulated by interested
stimulants, reactive oxygen species production of
peripheral circulating neutrophils, and plasma
immunoglobulin concentration were investigated
after three consecutive days of either AC or EA
treatments. Result from our study suggested that AC
and EA stimulation possessed anti-inflammatory
activity that is likely to be governed by modulation of
a cellular component of the innate immune system by
altering the production of inflammatory cytokine in
an up stream of the inflammatory cascade.
26 Effects of Cold and Hot Extraction on the
Physicochemical and Phytochemical Properties
of a Jamaica (Hibiscus Sabdariffa) Extract
Milena Ramirez-Rodrigues, Department ofFood
Science and Human Nutrition, College of
Agriculture and Life Science
Jamaica (Hibiscus sabdariffa L., family Malvaceae)
is a tropical annual shrub. Its dry calyx has
commercial value, and is used worldwide in cold and
hot beverages and as a food colorant. Red calyx is a
good source of anthocyanins and other polyphenols
associated with health benefits due to their
antioxidant activity. Finding the optimal conditions
for cold extraction may be a desirable alternative to
the traditional hot extraction. The objective of this
study was to compare the effects of cold (25C) and
hot (900C) extraction on the physicochemical and
phytohemical properties of the jamaica extract.
Conditions were determined for equivalent final
quality characteristics for cold and hot extraction
methods, providing more flexibility to jamaica
27 Impact of Feature Size, Geometry, and
Roughness of Engineered Surface
Topographies on Colonization and Biofilm
Formation of Marine Bacteria
Chelsea Magin, Department ofBiomedical
Engineering, College ofEngineering
The impact of feature size, geometry, and roughness
on the colonization of the marine bacteria Cobetia
marina was evaluated using engineered
microtopographies in polydimethylsiloxane elastomer.
A correlation has been made between an engineered
roughness index (ERI II) and the attachment of C.
marina. ERI II is a dimensionless ratio based on
Wenzel's roughness factor, the depressed surface
area fraction, and the number of geometrically
distinct features in the pattern. Engineered
microtopographies reduced the number of attached C.
marina bacteria cells compared to a smooth surface.
The level of attachment correlated very well with the
ERI II algorithm (R2=0.85, p=0.026).

28 Effects of the Circadian Cycle on
Neurogenesis in the Hippocampus and
Substantia nigra
Lan Hoang-Minh, Department ofBiomedical
Engineering, College ofEngineering
We tested whether new cells born in the
hippocampus and substantial nigra were more likely
to generate neurons during the dark phase of the
circadian cycle. Adult mice exposed to running
wheels were injected with the cell synthesis marker
bromodeoxyuridine, each 2 hours after lights "on", or
"off'. Sections were processed
immunohistochemically so that new cell number
could be estimated and new cell phenotype assessed
using confocal microscopy. Our results replicate
previous work showing that more hippocampal
neurons are generated during the dark phase of the
cycle. There was also a significant increase in the
number of new cells in the substantial nigra during the
dark phase, but they did not become neurons.
29 Inflammatory Molecules the Affect Adult
Hippocampal Neurogenesis
Aditya Asokan, Department ofBiomedical
Engineering, College ofEngineering
The knowledge of the behavior of transplanted neural
progenitors to treat neurodegenerative diseases is
important before such treatments can be used in the
clinic. Adult hippocampal neurogenesis is affected by
inflammation common to these diseases by altering
progenitor cell differentiation, and is restored upon
inflammatory blockade. Here we induce
inflammation in mice using LPS and detect the levels
of various cytokines in serum and brain tissue
homogenates to identify candidate molecules that
might be prime regulators of neuroinflammation and
have the greatest influence on adult neurogenesis.
30 Detection and Characterization of
PARACEST Contrast Agents
Heather Cornnell, Department ofBiomedical
Engineering, College ofEngineering
Paramagnetic Chemical Exchange Saturation
Transfer (PARACEST) utilizes an RF pulse to
saturate a small pool of bound protons at the
chemical shift induced by the paramagnetic
lanthanide complexes. Exchange between this
saturated proton pool and free protons in bulk water
results in decreased signal from bulk water.
Sensitivity to small concentrations of PARACEST
agent would be useful to increase the potential for
this mode of contrast generation. This abstract
investigates the detection of a europium based
PARACEST agent down to 0.4mM, 14.6T for
various pH's and temperatures.

31 Defective erythropoiesis in transgenic mice
expressing dominant negative upstream
stimulatory factor
Shermi Y. Liang, Department ofBiochemistry and
Molecular Biology
The transcription factor USF (upstream stimulatory
factor) is a ubiquitously expressed member of the
helix-loop-helix family of proteins, and is known to
be involved in the transcriptional regulation of many
genes. USF binds with high affinity to E-box motifs
and, through interaction with co-activators, aids in
the formation of transcription complexes. Previous
work demonstrated that USF regulates genes during
erythroid differentiation, including HoxB4 and 3-
globin. It is shown here that erythroid-specific
expression of a dominant negative mutant of USF, A-
USF, in transgenic mice leads to diminished
association of RNA polymerase II with the 3-globin
gene promoter. In summary, the data demonstrates
that USF is required for erythropoiesis.
32 Characterization of a Novel Protein Family
Involved in Metallocenter Biosynthesis
Crysten Haas, Department oJ \i, .'-. i. and
Cell Science, College ofAgriculture and Life
Zinc is an essential cofactor for numerous proteins,
where it serves both structural and catalytic roles.
However, little, if anything, is known regarding zinc
trafficking within the cell, especially when faced with
a zinc-limited environment. A comparative genomics
approach combined with a literature survey and
genetics has led to the identification of a novel family
of proteins we predict to be involved in zinc
homeostasis. This work tries to identify the protein
targets of YeiR and determine whether the function
of YeiR is typical of the protein family as a whole, in
order to reveal how this ubiquitous protein family is
involved in zinc homeostasis in prokaryotes as well
as higher eukaryotes.
33 Identification of New Transcription
Regulators in Lactic Acid Bacteria for Live
Vaccine Development
Pande, Santosh Gurunathrao, Department of
Microbiology and Cell Science, College of
Agriculture and Life Science
This research is focused on the identification of small
molecules which modulate the repression or
activation of gene mediated by transcriptional factors.
Using high throughput fluorescence based assay we
screened a library of- 1200 chemical compounds
and successfully identified two transcriptional factors
(LB6 and LB7) that belong to the LysR family of
transcriptional activators. Electrophoretic Mobility

effectors/ligands and DNA interactions in vitro
studies whereas RT-PCR is used for in vivo studies in
L brevis. Future research aims at the fusion of the
LB6 and LB7 promoters with the green fluorescent
protein to design a strong inducible expression
system in L brevis for live vaccine development.
34 G6, a Novel Small Molecule Inhibitor that
Supresses JAK2-dependent Erythroleukemia
Annet Kirabo, Department ofPhysiology and
Functional Genomics
Inhibition of Jak2 is an emerging therapeutic strategy
for hematologic disorders. Here we show that G6, a
Jak2 inhibitor developed in our laboratory suppresses
erythroleukemia in vivo. Injection of SCID-NOD
mice with human erythroleukemia cells resulted in
pathological appearance of blasts cells in blood,
increased spleen weight to body weight ratio, and
decreased myeloid to erythroid ratio. G6 treatment
decreased these effects in a dose-dependent manner.
Therefore G6 may provide effective molecularly-
targeted therapy in human erythroleukemia.
35 Impact of sunhemp mulch on Lesser
Cornstalk Borer, Elasmopalpus Lignosellus
(Zeller) (Lepidoptera: Pyralidae)
Harsimran K Gill, Department ofEntomology
and Nematology, College ofAgriculture and Life
Lesser cornstalk borer (LCB), Elasmopalpus
lignosellus (Lepidoptera: Pyralidae) is a serious pest
of beans and other crops. LCB infestation and
predators were compared among Sunhemp
(Crotolariajuncea) mulch, weedy and barren plots.
LCB attack was found to be significantly less in
mulch plots compared to others.
36 Evaluation of Alternative Hosts for
Development by "Corn Silk Flies"
Gaurav Goyal, Department ofEntomology and
Nematology, College ofAgriculture and Life
'Corn silk flies' are serious pests of sweet corn in
Florida and several Caribbean countries. Four species
of these flies, Euxesta eluta Loew, E. stigmatias
Loew, E. annonae (F.) and Chaetopsis massyla (F.)
(Diptera: Ulidiidae) have been reared from corn
grown in Florida. Corn is not available year round in
Florida, so experiments were designed to test the
hypothesis that these flies can develop on other host
plants. Lab studies were conducted to evaluate
locally grown vegetables, fruits and weeds as
potential developmental hosts for corn silk fly

37 Mid- to Late Holocene (5-3 ka) Origin of the
Modern Tonle Sap Lake System, Cambodia
Mary Beth Day, Department of Geological
Sciences, College ofLiberalArts and Sciences
As Southeast Asia's largest lake, Tonle Sap plays a
crucial role in Cambodia's culture and ecology. The
lake provides a habitat for >500 fish species and is
one of the most productive inland fisheries in the
world. It is a vital protein source that nourishes
Cambodians today and helped to sustain the ancient
Angkorian Empire. The paleolimnological record
may provide insight into the environmental
conditions of Lake Tonle Sap prior to its connection
with the Mekong. The ancient lake may serve as an
analog for a future Tonle Sap ecosystem in which the
annual flood pulse, and associated nutrient input, is
dampened or eliminated by damming of the Mekong
River.LCB attack was found to be significantly less
in mulch plots compared to others.
38 Apparent magnetic excursions in Arctic deep-
sea sediments and their origin
C i,,I, ii Xuan, Department of Geological
Sciences, College ofLiberalArts and Sciences
Natural remanent magnetization (NRM) of u-channel
samples collected from cores yields down-core
inclination patterns of positive and negative intervals
that mimic polarity zones. Thermomagnetic tests
indicate that the two components are likely carried by
an iron sulfide (greigite) and magnetite. The results
suggest that samples from negative inclination
intervals have a higher proportion of greigite but
lower proportion of magnetite. Furthermore, the
results tend to rule out pyrrhotite as the dominant iron
sulfide. We suggest that negative NRM inclinations
recorded in these Brunhes-aged high latitude deep-
sea sediments are possibly caused by magnetic
interactions between a secondary authigenic greigite
and a primary magnetite rather than any special
behavior of the geomagnetic field at these high
39 Nd Isotopic Evidence of Deglacial Antarctic
Intermediate Water in the North Pacific
Chandranath Basak, Department of Geological
Sciences, College ofLiberalArts and Sciences
Nd isotopes from fossil fish teeth and debris are a
potential water mass tracer. Initial Nd isotopic
analyses from marine sediment core from a water
depth of 705 m on the open margin off the western
coast of southern Baja California have been used to
test changes in deep ocean circulation proposed by
Marchitto et al. (2007). Their work suggests that
Antarctic Intermediate Water (AAIW) was
volumetrically more important along the Baja
California margin during deglaciation than it is today.

Schedule and Abstracts

This study will use the Nd data to quantify the %
North Pacific Intermediate Water and AAIW at the
Baja site before, during and after deglaciation.
40 Synthesis of Sol-gel Bioactive Glass
Microspheres by Gelation in an Emulsion
Scott Cooper, Department of Materials Science
and Engineering, College ofEngineering
Monodispersed, non-aggregated bioactive glass
microspheres would provide a well-controlled
material for numerous biomedical applications. A
process for making such microspheres was developed
through standard sol-gel processing. By forming an
emulsion of the aqueous sol, the morphology of the
bioactive glass phase was controlled to form
microspheres. Various factors of the emulsion were
tested for their influence on particle size and
dispersion. The ability to form hollow and solid
microspheres was also explored. The facile, low
temperature sol-gel process allows for the
incorporation of organic and biological molecules,
which provides a significant advancement in
materials for in tissue engineering and targeted drug
41 30 years of protection: is Pench Tiger Reserve
a success story?
Pinki Mondal, Department of Geography, College
ofLiberal Arts and Sciences
Parks are believed to protect forest from changes and
are established to maintain carbon sinks, protect
biodiversity, and stabilize global climate. However,
current controversies show skepticism in the
effectiveness of parks as management regimes.
Hence, evaluation of parks over time is important to
establish the effectiveness of parks as biological
refuges, specially in human-dominated landscape.
This study integrates advanced remote sensing and
GIS techniques to examine the changing landscape
patterns in and around Pench Tiger Reserve (PTR),
Maharashtra, India in the past decades.
