▼ Corrective schemes for facilitating continued
operation of dc-ac converters during internal and external
abnormalities are presented in this dissertation. While some of the
developed techniques are suited for any dc-ac converter topology,
most of the presented methodologies are designed specifically for
cascaded H-bridge (CHB) multilevel converters. While CHB provide
increased scalability and efficiency compared to traditional
topologies, these converters are more likely to experience internal
faults due to the additional components required. Realizing the
full potential of CHB converters requires fault tolerant
techniques, such as those demonstrated in this dissertation.
Adaptive sinusoidal pulse width modulation (ASPWM) is introduced in
this dissertation as a method which enables CHB to directly utilize
time-variant dc sources, increasing CHB flexibility when compared
to traditional pulse width modulation (PWM) methods which require
dc sources with equal magnitudes or with magnitudes existing in
specific ratios. Two alternative algorithms are presented to enable
ASPWM implementation, providing a trade off between system
performance and required sensor circuitry. This dissertation also
introduces a load independent analytical approach for identifying
discordant operating points, i.e. operating points where some cells
in an asymmetric CHB leg regenerate power while the overall leg
delivers power, or vice-versa. Identification of these points is
essential due to the deleterious effects which can result from
extended discordant operation, for instance overcharging of
batteries leading to lifespan degradation or even catastrophic
failures such as fires or explosions. Additionally, a method for
rapidly identifying, isolating, and verifying internal IGBT
open-circuit and gate-driver faults is presented in this
dissertation to address the increased probability of switch
failures occurring within CHB. The proposed approach enables
converter operation to continue in the event of gate-driver or
open-circuit faults, but avoids unnecessary converter
reconfiguration due to gate-misfiring faults. For a CHB leg with M
cells, the proposed technique identifies and isolates open-circuit
switch faults in less than 2M measurement (sampling) cycles, and
verification is completed in less than one full fundamental cycle.
Furthermore, this dissertation introduces a real-time implementable
atypical PWM technique which enables increased dc bus utilization
under a wide range of non-ideal operating conditions. While this
approach is suitable for a wide range of converters operating under
external abnormalities, for instance maximizing dc bus utilization
for converters providing auxiliary services such as
negative-sequence compensation, this approach also facilitates
operation of CHB with faulty cells. The proposed method can be used
with any control technique and any carrier-based PWM method,
enabling its implementation in both symmetric and asymmetric CHB.
In addition to these fault tolerant techniques, a novel approach
for analyzing the…

▼ Porcine reproductive and respiratory syndrome virus
(PRRSV) causes a tremendous economic loss in swine industry
worldwide. The capabilities to evade host immune responses and to
establish persistent infection are the two hallmark features of
PRRSV infection. In this dissertation, the research was mainly
focused on investigating the novel mechanisms underlying PRRSV
transmission and persistence.
In chapter 2, the research was
focused on an alternative pathway of PRRSV intercellular
transmission. Our data showed that intercellular nanotube
connections can be utilized for cell-to-cell spreading the core
infectious viral machinery (viral RNA, certain replicases and
structural proteins) of PRRSV. Live-cell movies tracked the
intercellular transport of a recombinant PRRSV that expressed green
fluorescent protein (GFP)-tagged nsp2 in a receptor-independent
manner. The cytoskeleton proteins F-actin and myosin-IIA were
identified as co-precipitates with PRRSV nanotube associated
proteins. Drugs inhibiting actin polymerization or myosin-IIA
activation prevented nanotube formations and viral clusters in
virus-infected cells. These data lead us to propose that PRRSV
utilizes the host cell cytoskeletal machinery inside nanotubes for
efficient cell-to-cell spread. This form of virus transport
represents an alternative pathway for virus spread, which is
resistant to the host humoral immune response.
In chapter 3, we
further showed that PRRSV infection could induce the formation of
nanotubes between infected and uninfected cells following a
ROS-dependent nanotube formation model. Co-culturing PRRSV-infected
cells with uninfected cells rescued PRRSV-induced cell death.
Mitochondrion was observed transferring from uninfected to
PRRSV-infected cells. Importantly, impaired formation of nanotube
or defective mitochondrion was unable to rescue infected cells from
apoptosis/necrosis. Certain PRRSV proteins were detected to
associate with mitochondria and transport from infected to
uninfected cells through TNTs. Our results suggest that
TNTs-transfer of functional mitochondria rescued PRRSV-infected
cells from apoptosis/necrosis in the early stage of infection. On
the other hand, mitochondria could be utilized as a cargo to
transport viral materials for spreading the infection.
In chapter
4, a novel mechanism s of PRRSV persistent infection has been
studied. In this study, a cellular model of persistent infection
was established. Strand-specific quantitative RT-PCR and RNase I
treatment analysis showed that double-stranded RNA (dsRNA)
conformation existed in persistently infected cells. This data has
been further confirmed in vivo by performing two independent PRRSV
persistence studies. Immunohistochemistry analysis showed that
viral dsRNAs were detected aggregating inside the germinal centers
of tonsils and lymph nodes from PRRSV persistence pigs, but RNA
array analysis further showed that dsRNA in lymphoid tissues had
limited ability to stimulate host antiviral responses during
persistent infection stage. These results suggest that…

▼ Research on contemporary sexism suggests that sexism
has many different forms and they influence women differently.
Evidence shows that women who experience subtle forms of sexism
(e.g., modern and benevolent sexism) feel anxious and less
competent, yet are less likely to identify these forms of sexism as
prejudice against women. Because research suggests that social
support is related to better psychological outcomes, we
hypothesized that higher levels of perceived social support would
be associated with better psychological outcomes among female
participants who experienced sexism. In addition, receiving a
supportive message after experiencing sexism would buffer the
negative psychological effects of sexism, and thus the participants
would perform better on a problem-solving task. However, the
results only partially supported the hypotheses. Higher levels of
perceived social support were indeed associated with better
psychological outcomes, but participants who experienced sexism did
not differ significantly from those who did not experience sexism
regarding psychological outcomes. Further, receiving social support
after experiencing sexism did not produce significant improvements
on the problem-solving task, though participants who experienced
modern sexism did report an increase in hostile affect if they did
not receive social support. Possible reasons for the findings are
discussed.

▼ Many crops grown in greenhouses are damaged by the
twospotted spider mite, Tetranychus urticae. The predatory mite,
Phytoseiulus persimilis, is a commercially-available predator that
is commonly used to control twospotted spider mites on greenhouse
crops; but its efficacy varies among crops, and it is generally
ineffective at low prey densities. In general, predator foraging
efficiency depends on how well predators find prey patches, the
length of stay in prey patches, and consumption of prey while in
prey patches. With respect to P. persimilis, I asked how this
predator responds to different prey distributions, as might be
encountered at different stages of spider mite infestations. I also
asked how components of foraging, namely consumption rate and
dispersal tendency, affected predator efficiency. To examine the
former, I established T. urticae eggs on 6-leafed cucumber plants
in two distributions. To examine the latter, I imposed artificial
selection on a population of P. persimilis to create a line that
exhibited extremely high consumption and one that demonstrated a
greater tendency for dispersal. Subsequently, foraging efficiency
was assessed by observing predator oviposition and consumption of
twospotted mite eggs on individual leaves of 6-leafed cucumber
plants. The number of eggs laid by predators corresponded to the
number of prey consumed regardless of predator line. In addition,
predators from both lines distributed their eggs proportional to
where they fed. However, prey consumption differed between selected
lines in response to prey distribution. Predators selected for high
consumption fed more on the basal leaf where they were released;
whereas prey consumption by the high dispersal and control lines
were more evenly distributed throughout the plant. These
results
contribute to a better understanding of how foraging behavior is
modified in plant landscapes under different levels of expression
of foraging traits. They also indicate that predator release
strategies likely would need to modified in accordance with the
kind of foraging trait(s) used in artificial selection programs. In
general, my research, when combined with future studies at a
broader landscape level, will facilitate decisions by biological
control practitioners about whether changes in foraging efficiency
resulting from artificial selection justify the cost investment of
producing selected lines of P. persimilis

▼ This dissertation consists of three essays which use
the Arab League countries as a natural setting for empirical
research quantifying the effects of different features of this
region’s trade policies on member countries.
The first essay
examines the effects of the different features of the Arab League’s
trade policy (preferential trade agreements, market power, and
bound tariffs) on the multilateral tariffs applied by its member
countries. Overall, our results suggest that preferential
agreements have a building block effect on multilateral tariffs
because Arab League members tend to lower their applied
Most-Favored Nations (MFN) tariffs as they grant enhanced
preferential access to their partners. Unlike earlier studies, we
find that the formation of a customs union (CU) among Arab League
members led to the same degree of external trade liberalization
than forming a free trade area (FTA). Moreover, we find that high
degree of importer market power tends to mitigate the building
block effect of forming preferential trade agreements.
The second
essay investigates the effects of trade policy uncertainty on the
entry decisions of exporters to Arab League markets. Using a
product-level dataset on World Trade Organization (WTO) members
exporting to Arab League countries for the years 1998-2015, we
provide empirical evidence that trade policy uncertainty, a result
of significant gaps between tariff bindings and applied tariffs
(tariff water), led to the reduced entry of exporters in Arab
League markets. We then extend our analysis to investigate the
effects of policy uncertainty combined with additional uncertainty
related to falling incomes associated with the 2007-2010 worldwide
economic downturn. Our results suggest that this macroeconomic
shock has contributed to a considerably more uncertain economic
environment, thereby affecting the decision to enter these markets.
We also analyze exporter decisions to enter new markets when the
Arab League importing country exhibits high levels of market power.
We find empirical evidence confirming that the effects of
uncertainty on entry are magnified in the presence of high levels
of market power.
The third essay examines the effects of trade
preferences granted by members of the Arab League on these
countries’ international import prices. According to the
international trade literature, preferential trade agreements
(PTAs) lower trade barriers on imported goods from preferential
partners, leading to consumer gains from better quality products,
lower prices for existing products, and deteriorating terms of
trade of the importing country relative to preferential partners.
Using product-level data from 1998-2011 with information on
quality-adjusted international import price indexes, applied MFN
tariffs, preferential tariffs, and market power for eleven Arab
League countries, we estimate the international import price
effects of trade agreements formed by Arab League countries. We
find that a one percentage point decrease in applied MFN tariffs
leads to a fall in…

▼ Similar to their urban counterparts, rural communities
consider preservation of a site based on their most vital economic
features. With the growing minority and non-white cultures becoming
more predominant in American society, so too has the culture and
significance of historic events changed. More emphasis is now on
the surrounding environment of those landmarks historically
preserved rather than just the landmarks themselves. And in turn
with the environment, more grants and awards are passed down to
those sites and locations that provide more options to limiting
excess space and energy while utilizing them to the fullest
potential. Some conflicts still occur in relation to preserving
historical integrity with development, but the total consensus is
that historic preservation provides economic benefit more than
loss.

▼ This report analyzes construction delivery method use
in the United States Air Force (USAF) and determines which methods
prove to be more effective and efficient and which construction
delivery methods should be pursued. The construction delivery
methods undergoing analysis are design-bid-build (DBB),
design-build (DB), construction manager at risk (CMAR), and
integrated project delivery (IPD). A literary review of previous
studies on the aforementioned construction delivery methods,
particularly regarding studies performed within the United States
(US) federal government and US military branches is presented. The
benefits for each construction delivery method is discussed, as
well as the common obstacles and problems with each one. A survey
was conducted in which 145 contracting officers in the USAF
responded, and the survey results are analyzed and compared to
those found in the literary reviews. Two major conclusions drawn
from the literary review and survey are that DB should be used over
DBB in most cases, and IPD should be examined as a viable USAF
construction delivery method candidate. With the literary review,
DB is seen as superior to DBB in almost every regard, and the
surveyed contracting personnel tended to favor DB over other
construction delivery methods. For higher complexity or large
projects DBB can offer more control but sacrifices timeliness. IPD
has data that suggests it can be a construction delivery method
that is better than DB and DBB but currently cannot legally be used
for USAF construction contracts because the Federal Acquisition
Regulation (FAR) restricts it. DB should be defaulted to as the go
to construction delivery method if the project is a viable
candidate and there are not extenuating factors that suggest
another method be used. It should be explored what parts of IPD can
be implemented for now, while larger legislative changes to the FAR
are made at the congressional level.

▼ The rheological properties of two waxy and two normal
wheat flours were investigated and the observed differences between
them were explained by biochemical analysis. Protein analysis
showed that waxy flour had lower polymeric to monomeric ratio (0.70
and 0.58 for waxy flour compared to 0.75 and 0.76 for normal flour)
and higher gliadin content in waxy wheat dough (43.9 and 47.3 for
waxy wheat dough compared to 41.0 and 41.7 for normal wheat dough).
Waxy flour had high amounts of insoluble (IPP) and unextractable
(UPP) polymeric protein despite the poor dough forming properties
of the waxy flours, contrary to previous correlations made between
IPP, UPP and dough strength. Gluten index determination showed a
clear difference between waxy and normal flour; there was no gluten
aggregation when the waxy samples were tested. The determination of
gluten index done on a variety of water washed flour samples
indicated that the water-extractable fraction may contain compounds
that affect gluten aggregation. HPLC analysis coupled with
arabinose/xylose ratio and viscosity determination of the water
extractable portion of the flour indicated that water extractable
arabinoxylans (WEAX) in waxy wheat flour were different in
composition and conformation. Further research is needed to
determine if they could be responsible for the lack of gluten
aggregation in waxy flour.

▼ This thesis is focused on the use of networks to
identify potentially malicious Android applications. There are many
techniques that determine if an application is malicious, and they
are ever-changing. Techniques to identify malicious applications
must be robust as the schemes of creating malicious applications
are changing as well. We propose the use of a network-based
approach that is potentially effective at separating malicious from
benign apps, given a small and noisy training set.
The
applications in our data set come from the Google Play Store and
have been scanned for malicious behavior using Virus Total to
produce a ground truth dataset. The apps in the resulting dataset
have been represented as binary feature vectors (where the features
represent permissions, intent actions, discriminative APIs,
obfuscation signatures, and native code signatures). We use the
feature vectors corresponding to apps to build a weighted network
that captures the \closeness" between applications. We propagate
labels, benign or malicious, from the labeled applications that
form the training set to unlabeled applications (which we aim to
label), and evaluate the effectiveness of the proposed approach in
terms of precision, recall and F1-measure.
We outline the
algorithms for propagating labels that were used in our research
and discuss the fine tuning of hyper-parameters. We compare our
results to known supervised learning algorithms, such as
k-nearest-neighbors and Naive Bayes, that can be used to learn
classifiers from the training labeled data and subsequently use the
classifiers to label the unlabeled test data. We discuss potential
improvements on our methods and ways to further this
research.

▼ Precise water application conserves resources, reduces
costs, and optimizes plant performance and quality. Existing
irrigation scheduling utilizes single, localized measurements that
do not account for spatial crop water need; but, quick,
single-point sensors are impractical for measuring discrete
variations across large coverage areas. Thermography is an
alternate approach for measuring spatial temperatures to quantify
crop health. However, agricultural studies using thermography are
limited due to previous camera expense, unfamiliar use and
calibration, software for image acquisition and high-throughput
processing specifically designed for thermal imagery mapping and
monitoring spatial crop water need. Recent advancements in thermal
detectors and sensing platforms have allowed uncooled thermal
infrared (TIR) cameras to become suited for crop sensing.
Therefore, a small, lightweight thermal infrared imaging system
(TIRIS) was developed capable of radiometric temperature
measurements. One-time (OT) and real-time (RT) radiometric
calibrations methods were developed and validated for repeatable,
temperature measurements while compensating for strict
environmental conditions within a climate chamber. The Tamarisk®
320 and 640 analog output yielded a measurement accuracy of ±0.82°C
or 0.62ºC with OT and RT radiometric calibration, respectively. The
Tamarisk® 320 digital output yielded a measurement accuracy of
±0.43 or 0.29ºC with OT and RT radiometric calibration,
respectively. Similarly, the FLIR® Tau 2 analog output yielded a
measurement accuracy of ±0.87 or 0.63ºC with OT and RT radiometric
calibration, respectively.
A TIRIS was then built for
high-throughput image capture, correction, and processing and RT
environmental compensation for monitoring crop water stress within
a greenhouse and temperature mapping aboard a small unmanned aerial
systems (sUAS). The greenhouse TIRIS was evaluated by extracting
plant temperatures for monitoring full-season crop water stress
index (CWSI) measurements. Canopy temperatures demonstrated that
CWSI explained 82% of the soil moisture variation. Similarly,
validation aboard a sUAS provided radiometric thermal maps with a
±1.38°C (α=0.05) measurement accuracy. Due to the TIR cameras’
performance aboard sUAS and greenhouse platforms, a TIRIS provides
unparalleled spatial coverage and measurement accuracy capable of
monitoring subtle crop stress indicators. Further studies need to
be conducted to produce spatial crop water stress maps at scales
necessary for variable rate irrigation systems.

▼ Carbonate reservoir characterization introduce
challenges that constantly require updates based on new seismic and
production data. Understanding the connection between seismic
response and litho-petrophysical properties is a crucial component
to producing tangible results in hydrocarbon reservoir
characterization, particularly in carbonate reservoirs. Applying
models in seismic interpretation is essential to integrating data
from a variety of disciplines including geology, geophysics,
petrophysics and reservoir engineering.
In this study, three
post-stack seismic attributes (instantaneous bandwidth and
peakedness along with volume attributes such as Root Mean Square -
RMS energy) are used to distinguish and identify seismic classes
pertaining to variations in litho/petrophysical facies from the
Mississippian saline aquifer hosted in a carbonate reservoir from
the Wellington Field, Sumner County,
Kansas.
Neutron porosity,
bulk density, and sonic well logs provided a correlation with
seismic amplitude, which in turn reflects reservoir properties
associated to acoustic impedance. Neutron porosity logs were
characterized into three classes. Class one representing a porosity
less than eight percent, Class two representing a porosity class of
greater than eight and less than twelve percent and Class three
representing a porosity greater than twelve percent.
The
impedance differences across a seismic reflector are the
controlling parameter of reflectivity. By having seismic and well
log data sets provide the connection to characterize the reservoir
to be modeled for porosity prediction based on amplitude and
seismic facies classification for the effects of enhanced oil
recovery (EOR) or geological sequestration of CO2.
Using an
unsupervised neural network and selecting three facies classes to
correlate with three petrophysical classes. Three well-log classes
are defined to describe the reservoir in terms of porosity using
neutron porosity well logs. Seismic facies three has the highest
porosity (greater than 12 percent), landed in structurally low
areas and likely resemble dolomite prone area. The second-facies
has porosity between 7 and 13 percent resemble a transitional zone
from structurally low to high showing reworked brecciated limestone
facies from CT scans. Seismic facies one has porosity less than 11
percent and resemble a structurally high erosional area.
The
seismic facies prediction map was constructed by correlating
reservoir porosity using neutron porosity logs and seismic
amplitude attributes in a carbonate reservoir. Due to the nature of
elastic properties and mineralogy of carbonates that render the
reservoir porosity the most significant factor controlling
amplitude variation.
Seismic amplitude attributes (bandwidth,
peakedness, and RMS energy) reveal some unexpected features
interpreted as small-scale faults associated with the Nemaha
Uplift. Using the same three attributes as an input for an
unsupervised neural network and selecting three seismic facies
produces results that correlate with…

▼ Clostridiodes difficile, a Gram-positive, anaerobic
bacterium, is the leading cause of antibiotic-associated nosocomial
diarrhea in North America. C. difficile causes around half a
million infections per year and costs about 4.8 billion dollars in
healthcare bills. C. difficile’s major virulence factors are the
extracellular toxins A and B. The disease is prevalent in the
nosocomial environment and challenging to keep in check because of
the highly resistant spores produced by the bacteria. Like many
other pathogenic microbes, C. difficile virulence factors are
strictly regulated in response to the nutrient availability to the
cell. Glycogen is a storage carbon that many organisms use as a
form of stored energy to use during the starvation condition. C.
difficile genome harbors a glycogen biosynthesis operon, and we
explored the role of glycogen in C. difficile growth and virulence
by creating a mutant strain with a disrupted glgC gene of the
operon. The resulting mutant was incapable of glycogen accumulation
and produced very few spores, signifying glycogen is required for
efficient sporulation in C. difficile. In correlation with glgC
mutant’s higher toxin production and faster growth rate compared to
its parent counterpart in in vitro condition, our animal infection
model study showed that glycogen mutants are significantly more
virulent in in vivo conditions. The second part of the thesis
explores the role of cellobiose phosphoenolpyruvate:carbohydrate
phosphotransferase system (PTS) operon in C. difficile virulence.
In C. difficile, the cellobiose PTS operon is positioned from base
3287617 to 3291739 in the R20291 hypervirulent strain genome. The
operon consists of 5 genes with putative functions of a PTS system
and cellobiose catabolism. Cellobiose is a complex carbohydrate
abundant in human gut originating from dietary cellulose and has
documented role in many pathogens’ virulence. As such, we
hypothesized that cellobiose metabolism plays a significant role in
C. difficile virulence. CD2781 is a putative GntR class
transcriptional regulator. Because of its immediate vicinity to the
Cellobiose PTS operon and putative function we hypothesized that it
is a regulator for Cellobiose PTS operon. To test our hypothesis,
we created mutant strains R20291::licB and R20291:: cd2781 using
ClosTron mutagenesis system. The resulting mutants showed a
differential level of virulence factors, which were also
corroborated by different molecular techniques. We also identified
the CD2781 as a negative transcriptional regulator of cellobiose
operon, characterized its target binding attributes, determined its
role in virulence, and named it as CelR. Our hamster infection
model study demonstrates that cellobiose PTS operon is essential
for colonization, pathogenesis, and recurrent infection of C.
difficile in hamsters. These works, in conclusion, demonstrate that
both glycogen and cellobiose metabolism plays a significant role in
C. difficile virulence.

▼ Methods of measuring antibiotic use were explored
using data collected from a convenience sample of 29 US dairy farms
for the calendar years of 2016 and 2017. Multiple on-farm data
sources included handwritten records and four software systems.
Data from each source were standardized to a common format for
analysis. Antimicrobial use is reported as regimens per cow year
with the regimens defined at the product level by route of
administration, number of administrations, time frame between first
and last administration, grams per regimen, and grams per
administration. The primary goal of this study was to identify
which measures might be useful for guiding stewardship at the farm
level, and to describe the nuances associated with different
methods of measurement. For this reason, care was taken to maintain
the association between use and the reason for use (detected
disease) for all measures reported.
This method of reporting
provided enough granularity to compare different methods of
antimicrobial use measurement. Measurements of overall use by
regimens per cow year indicate that most use occurs as intramammary
treatments and cephalosporins are the most commonly used antibiotic
class. Use measured by grams per cow year indicates that both Dry
Cow therapy and non-intramammary (Other Treatments) contribute
significantly to overall use, and use in the penicillin class
predominates. Comparisons of measures by regimens, grams, defined
daily doses (DDD), defined course doses (DCD) and days of therapy
(DOT) are evaluated at the farm level. With the exception of grams,
all comparisons of these measures have correlations greater than
0.7 for all categories of use. Potency confounds measures of active
substance weight causing use measured as grams of antimicrobial to
not correlate as well with other measures (correlations <0.5).
This lack of correlation is especially apparent for dry cow therapy
where the correlation between grams and other measures is -0.06.
These comparisons raise questions about the relationship between
use measures and resistance selection pressure. Further study is
needed to identify the exact relationship between use measures and
resistance selection pressure, as well as to identify treatment
outcome parameters that should be assessed to ensure that animal
welfare is appropriately monitored as antimicrobial stewardship is
advanced.

▼ This paper presents the results of an experiment that
was purposed with introducing the physical feasibility of a
conceptual product that would mechanically reduce frictional
resistance of schedule 40 PVC conduit elbows during the
installation of large conductors. In the current construction
industry, there is a well established and code driven convention
for the construction of PVC conduit. For the installation of
building service conductors, significant energy is required to pull
conductors through the conduit. The service feed is the most
expensive and restrictive pull on most projects strictly due the
weight of the large conductors which are heavily resistant to
deformation. The forces involved necessitate stringent requirements
on maximum pull lengths and maximum degrees bent between pull
boxes. Cost and risk of costly installation damage are also major
characteristics of service feed pulls. The resistance to pulling
and highest concentrations of internal forces throughout any
conductor pull is located at the elbows or bends. This study is a
scaled experimental-based initial establishment of expected
evidence to support the feasibility of a product that would
essentially reduce the required force to pull large conductors.
This product is idealized as a factory PVC elbow that contains
mechanical rollers along the inside face of the elbow where the
conductors theoretically make the most contact during pulling. This
product will ultimately be more expensive, but would be expected to
benefit the project by reducing installation time, possibly reduce
the number of pull boxes required, and reduce the risk of damaging
conductors or conduits. The experiments described in this paper
reflect a small-scale set that establishes trends of varying any
one significant parameter for single conductor pulls through a
single ninety-degree factory PVC elbow. While further research into
multi-conductor feeders must be conducted in order to establish
full justification for the product development was expected at the
onset, the results of this study show that even further additional
research must be conducted to resolve an ambiguity on which a
definitive conclusion depends. Due to unforeseen or predicted
parameters impacting the reduction of frictional resistance
throughout the experimentation, the results both support and
counter any benefit of applying mechanical means to reduce
frictional resistance. The percentages of reduction range from -37%
to +24% across the study’s results. The hypothesized sources of the
ambiguity that counter expectations can only be verified by future
studies. However, the evidence from this study can become
definitively directional for the pursuit or lack there of for
further investigating the benefits of the idealized
product.

self-regulation of behavior theory is that human action is driven
by attainment of goals and the degrees and forms of behavior
expressed by an individual can be quantified by specific
personality characteristics which affect both the response to, and
velocity toward, those goals (Carver & Scheier, 1998). A survey
administered to high net worth individuals (i.e., net worth of $1
million or greater) with a oversampling of high net worth
individuals who have filed bankruptcy focused on self-reporting
personality measures key to the self-regulation of behavior theory,
such as optimism-pessimism and appetitive motives. By utilizing
data gathered from high net worth individuals, a t test was used to
examine mean differences in the personality characteristics of high
net worth individuals who have filed bankruptcy and high net worth
individuals who have not filed bankruptcy. The debt-to-income and
debt-to-assets ratios were utilized as the dependent variables in
an OLS regression analysis to analyze if any of the variables of
interest significantly influenced the debt-to-income ratio, or DTI,
or debt-to-assets ratio, or debt-ratio. This was followed by a
logistic regression analysis predicting the odds of a bankruptcy
filing based on the variables of interest. Potential differences in
personality and behavior may explain wealth management issues that
exist between high net worth individuals who have filed bankruptcy
and high net worth individuals who have not filed
bankruptcy.

▼ A flexible distribution is an adaptive response that
allows animals to take advantage of spatial variation in the
fluctuation of resources. Distribution of mobile organisms is
complex so multi-metric patterns derived from dynamic distribution
trajectories must be deconstructed into simpler components for both
individuals and populations. Tagging and tracking fish is a very
useful approach for addressing these fisheries research questions,
but methodological challenges impede its effectiveness as a
research tool. Here, I developed and evaluated a high-retention,
high-survival tagging methodology for catfish. Then, I integrated
multiple distribution metrics to identify if sites within an
ecosystem function differently for mobile predators. Finally, I
determined if distinct groups of individuals existed, based on
distributional patterns. In the appendices, I test sources of
variation in system-wide detections (i.e., season, diel period,
size, and release location) and provide additional details on
methods and interpretation of the results. To address these
objectives, I tracked 123 acoustically tagged (VEMCO V9-V13) Blue
Catfish (Ictalurus furcatus mean: 505.3 mm TL; SE: 12.3 mm; range:
300-1090 mm) from June through November, 2012-2013, in Milford
Reservoir, KS. Across the five months, 85.4-100.0% of the tagged
Blue Catfish were detected at least once a month by an array of 20
stationary receivers (VR2W), a detection rate much higher than
rates reported in the literature for catfish (38%). Blue Catfish
were consistently aggregated in the northern portion of the middle
region of Milford Reservoir. Using three metrics (population
proportion, residence time, and movements), I found four types of
functional sites that included locations with (i) large, active
aggregations, (ii) exploratory/transitory functions, (iii) small,
sedentary aggregations, and (iv) low use. I also found that tagged
Blue Catfish clustered into three groups of individuals based on
distribution. These included (1) seasonal movers, (2) consistent
aggregations across seasons, and (3) fish exhibiting site fidelity
to Madison Creek. Sites with different functions and groups of
individual fish were related but not the same. My approach to
looking at multiple responses, functions of sites, and individual
groupings provided new insights into fish ecology that can advance
fisheries management of mobile predators.

▼ Acculturation can be a difficult process for many
immigrants, and because there is a large number of Iranian
immigrants living in the United States (over one million), the
focus of this study is to understand how women cope with moving
from a country with conservative standards to a more liberal
country and the role dress plays in their acculturation process.
Specifically, the purpose of this study is to: 1) explore Iranian
dress standards and the effect these standards have on
Iranian-American women’s lives; 2) gain understanding of the role
of dress in women’s transition from Iranians to Iranian-Americans;
3) apply Abraham Maslow’s hierarchy of needs motivational model to
the women's acculturation process; and 4) compare two distinct
generations of women—women born before the 1979 Islamic Revolution
and women born after the Revolution. This study utilized a
qualitative approach and collected data through semi-structured
interviews with 11 women.
The women did not express any traumatic
psychological effects caused by the conservative dress standards in
Iran. The main impact of the dress standards was the physical
discomfort caused by wearing the hijab in hot weather. Dress played
a significant role in the women's transitions process. More freedom
in dress in the United States has allowed the women to express
themselves much more than when they lived in Iran, leading to
higher self-esteem and confidence levels. The women expressed a
desire to sustain their Iranian heritage, and both generations
shared similar perceptions of American dress standards prior to
immigrating to the United States. Differences included higher
consumption levels by the younger generation and their higher
knowledge about the fashion industry and trends.
The findings can
be useful for Iranian women as they transition to an
Iranian-American lifestyle. Additionally, it can also be beneficial
to women from other countries who share similar experiences.
Furthermore, the results may assist in aiding different
organizations which help Iranian women integrate into the U.S.
culture. Finally, retailers with target markets similar to the
women of this study can use the findings to better understand the
habits, needs, motives, and overall consumer behaviors of their
clientele.

(more)
▼ Mule deer (Odocoileus hemionus) and white-tailed deer
(O. virginianus) are common sympatric deer species in the Great
Plains and western United States that have exhibited divergent
population trends temporally and spatially. Mule deer populations
are declining and contracting to the west while white-tailed deer
populations are expanding. Species-specific differences in fawn
recruitment is one proposed explanation for these observed trends,
although the underlying causes remain unknown. To determine if
landscape or other habitat changes are affecting the two deer
species in different ways, we studied bed-site selection of mule
deer and white-tailed deer fawns in western
Kansas at microhabitat
and landscape scales. We also assessed how fawn intrinsic factors,
doe maternal condition, and bed-site habitat characteristics
influenced survival of mule deer and white-tailed deer fawns. In
February 2018 and 2019, we captured 120 adult does (60 mule deer,
60 white-tailed deer) using helicopter net-gun techniques and
deployed 120 vaginal implant transmitters (VITs) synchronized with
GPS collars deployed on does. Upon VIT expulsion, a birthing event
notification was triggered, which narrowed search efforts for
fawns. We captured and radio-collared 100 fawns (53 mule deer, 47
white-tailed deer) during 12 May- 23 June in 2018 and 2019. Fawns
were visually located daily using ground-based radio-telemetry and
we assessed bed-site selection, cause-specific mortality, and
survival rates until fawns reached 10 weeks of age. Overall, fawn
survival was low (0.32 ± 0.06) and did not differ between species
(mule deer: 0.25 ± 0.08; white-tailed deer: 0.41 ± 0.08). Adult
chest girth was positively associated with 70-day white-tailed deer
fawn survival, longer fawn body length increased 7-day white-tailed
deer fawn survival, and fawn sex best predicted 7-day mule deer
fawn survival. Model uncertainty indicated fawn intrinsic factors
and maternal conditions may be poor predictors of fawn survival.
White-tailed deer survival was lower for fawns with more woodland
in their home ranges and mule deer fawn survival exhibited a
positive quadratic relationship with the amount of grassland within
the home range. Mule deer fawn survival increased with the amount
of edge and disaggregation within a home range, but landscape
configuration did not explain survival of white-tailed deer fawns.
We analyzed microhabitat characteristics at 2689 fawn bed-sites and
2689 paired random points. Bed-site selection differed by species;
however, vegetative structure was the most influential microhabitat
characteristic for both deer species. Mule deer fawns selected for
75% visual obstruction 8.4 dm tall, less grass cover, more
succulent cover, and 56% shrub cover at bed-sites. White-tailed
deer fawns selected for 25% visual obstruction 9.2 dm tall, 71%
forest canopy cover, and less grass cover and bare-ground at
bed-sites. The two species also showed differences in landscape
selection. The odds of a white-tailed deer fawn bed-site increased
5.88 times in woodlands,…

▼ This thesis was written as a business plan for the
purpose of securing funds for a new micro distillery.
Wheat
State
Distilling is an artisan distillery, manufacturing and selling
premium hand-crafted spirits from the regions finest ingredients. I
plan to distill premium vodka, whisky, bourbon, rum, gin and
liqueurs as well as a luxury line of reserve products.
Kansas
established a micro-distillery license in July 2012 that opens up
the market to this new type of business. The micro-distillery trend
is growing across the U.S. and I plan to establish myself as a key
player in the region. I will be entering the market early in the
industry’s life cycle when consumer interest and demand are high.
The proposed location in Wichita
Kansas takes advantage of the
largest city in
Kansas with a metro area population of 630,721 in
2011. The location has visible signage from Interstate 135. The
distillery will offer tours and a tasting room. We are able to give
customers free samples and sell cocktails to induce purchase. We
will use direct sales as well as restaurant and liquor store sales
thru distributors.
I will be marketing my premium products to
upper-middle class and wealthy consumers. My extensive product line
will allow marketing to a wide age range and to both sexes. We will
focus on online and social media as well as distributor incentives
and in-store promotions. Participation in local and regional events
for sampling and advertising will increases brand awareness.
Analysis of monthly production levels of each of the proposed
product has been completed to maximize profits considering time and
equipment constraints, cost of inputs and sale price. Regression
analysis has been completed examining many factors that contribute
to the selling price of micro distilled spirits.
Financial models
for years one through ten with risk analysis are included. If I
reach my sales goals of 25,000 cases per year by year five, which
is equal to my closest competition, High Plains Distilling, there
is a potential for $548,500 or more per year in profit.
I am
seeking a loan for $300,000.

▼ The objectives of these studies were to determine how
consumer palatability ratings of beef strip loin steaks and ground
beef are affected when products are identified with a brand, USDA
grade, or product type. Strip loins were selected to represent five
quality levels and six ground beef treatments were chosen,
representing a variety of fat levels and product types. After aging
steaks for 14 d and ground beef for 8 d, 2.5 cm steaks and 151.2 g
patties were formed. Consumer panelists evaluated samples for
tenderness, juiciness, flavor liking, and overall liking as well as
texture liking for ground beef samples. Additionally, consumers
rated each palatability trait as either acceptable or unacceptable
and rated the sample as either unsatisfactory, everyday quality,
better than everyday quality, or premium quality. Samples were fed
in two rounds – blind and informed testing. In the first round of
blind testing, consumers were served one sample from each treatment
with treatments not disclosed. For the second round of informed
testing, USDA grade, or product information was disclosed prior to
sampling. Samples evaluated by consumers were paired for blind and
informed testing. During blind testing, Certified Angus Beef (CAB)
steaks rated similar (P > 0.05) to Choice for all palatability
traits; however CAB rated greater (P < 0.05) than Choice for all
traits for informed testing. Additionally, Angus Select and Select
steaks were rated similar (P > 0.05) when tested blind, but
Angus Select was rated greater (P < 0.05) than Select for flavor
and overall liking when treatment was informed. Prime, CAB, and
Angus Select had increased (P < 0.05) ratings for flavor and
overall liking due to brand disclosure. However, Choice and Select
samples did not receive any increase (P > 0.05) in ratings for
palatability traits when brand was informed. Multiple traits were
rated greater for Prime, CAB, and Angus Select products indicating
these products received a "brand lift" (change in ratings due to
brand knowledge) in palatability due to brand identification.
However, when brand information was disclosed for Choice and Select
steaks, consumers indicated no increase in palatability perception.
Few differences were observed in blind testing for ground beef;
however, during informed testing, 90/10 CAB ground sirloin rated
greater (P < 0.05) than all other products for all palatability
traits besides juiciness. Increased (P < 0.05) ratings were
found for CAB products for multiple traits while the only
non-branded product that received increased (P < 0.05) ratings
was 90/10 ground beef during informed testing. There were few
differences among ground beef products when tested blind,
indicating that during blind testing, brand, fat percentage, and
subprimal source have little effect on ground beef palatability.
However, when product and brand were identified, multiple
treatments received increased ratings for palatability traits
indicating branding and product type knowledge influence the
palatability of ground beef.

Nonlinear

▼ This dissertation presents nonlinear control schemes
to improve the productivity and lifespan of doubly fed induction
generator (DFIG)-based and permanent magnet generator (PMG)-based
variable speed wind turbines. To improve the productivity, a
nonlinear adaptive control scheme is developed to maximize power
capture. This controller consists of three feedback loops. The
first loop controls electrical torque of the generator in order to
cancel the nonlinear term of the turbine equation of motion using
the feedback linearization concept. The nonlinearity cancelation
requires a real-time estimation of aerodynamic torque. This is
achieved through a second loop which estimates the ratio of the
wind turbine power capture versus the available wind power. A third
loop utilizes this estimate to identify the shaft speed at which
the wind turbine operates at a greater power output. Contrary to
existing techniques in literature, this innovative technique does
not require any prior knowledge of the optimum tip speed ratio. The
presented technique does not need a dither or perturbation signal
to track the optimum shaft speed at the maximum power capture.
These features make this technique superior to existing methods.
Furthermore, the lifespan of variable speed wind turbines is
improved by reducing stress on the wind turbine drivetrain. This is
achieved via developing a novel vibration mitigation technique
using sliding-mode control theory. The technique measures only
generator speed as the input signal and then passes it through a
high-pass filter in order to extract the speed variations. The
filtered signal and its integral are then passed through identical
band-pass filters centered at the dominant natural frequency of the
drivetrain. These two signals formulate a sliding surface and
consequently a control law to damp the drivetrain torsional stress
oscillations caused by electrical and mechanical disturbances. This
technique provides a robust mitigation approach compared with
existing techniques. These control schemes are verified through
holistic models of DFIG- and PMG-based wind turbines. Except for
wind turbine aerodynamics, for which an existing simulator is used,
the developed models of all components including DFIG, PMG,
converters, multi-mass drivetrain, and power line are presented in
this dissertation.

▼ The first step of accessing any resource over the
internet is to find the IP address of the hosting server
corresponding to the easy to remember domain name. For this
purpose, the Domain Name System (DNS) was introduced in 1985. We
can think of DNS as the phone-book directory of the internet. DNS
is fundamental to the proper functioning of the modern internet and
without DNS it will be very difficult, if not impossible, to
navigate the modern internet.
However, like any tool, it is being
used for both benign and malicious purposes. Malicious programs use
algorithmically generated domains to rendezvous with their command
and control server to receive tasks to be performed. DNS has also
been used as a covert channel for data exfiltration. Analysis of
DNS logs can reveal suspicious domains queried by infected hosts
and thus can help prevent and reduce security incidents in a
network.
Due to high volume and distributed nature, capturing,
logging and analyzing DNS data is non-trivial. In this thesis, we
provide a framework for capturing, logging, aggregating and
analyzing DNS data and show the results by applying our methods to
a
university-wide DNS server. We were able to find hosts which were
making Web Proxy Auto Discovery(WPAD) queries which is used by
hosts to automatically find and use web proxy servers available in
a network but also makes those hosts vulnerable to
Man-in-the-Middle(MITM)attack by rogue hosts connected to the same
network. The framework also helped us quickly detect and find all
hosts in our network which were infected by backdoor put in
CCleaner, very popular utility software for maintaining Microsoft
Windows systems. Investigation of suspicious domains reveals hosts
that we believe are running Potentially Unwanted Programs
(PUP).

▼ Historically, industrial riverfronts often polluted
waters and sites with chemicals, leading to degraded ecosystem
health and reduced numbers of aquatic wildlife downstream. These
sites currently pollute the environment through residual chemicals
and waste left behind by industrial-era production factories. Urban
riverfront redevelopment offers many possibilities to restore
wetland ecosystems and reestablish site connections to surroundings
through human access. By redeveloping urban rivers for wetland
protection and stormwater management, cities can begin to regain
their connections with the landscape while providing resilient
ecosystems through restoration. This proposal identifies
possibilities for riverfront redevelopment as wetlands and tools
for restorative action aiding increased human access and wildlife
health. A stormwater management plan utilizing phytotechnology is
proposed for the ARMCO Site at 7000 Winner Rd.
Kansas City, MO, a
former steel manufacturing site, adjacent to the Missouri River and
Blue River waterways. Using plant material and landscape design,
the ARMCO riverfront has been redesigned to unlock the full
potential of treatment wetlands and showcase emerging treatment
methods that could soon become typical cleanup procedure. A
template for remediation design has been created with the
techniques identified for remediation, stormwater treatment, and
habitat creation outlined in the master plan proposal. Nine
precedent studies have been used to identify key concepts for
design phasing aimed at human accessibility and modifications of
restorative tools. Careful deliberation of stormwater containment
and flood plain levels define site layout while contributing design
responses adaptable for year-round functionality coupled with
landscape interest for each season. The techniques and planting
palette have been tailored to address the specific site
contaminants for the Missouri River riverfront but are adaptable
for various contaminants and ecosystems.

▼ The United States holds a rich industrial history that
is still seen today from architecture and the sites that hold them.
Most of these sites have already been demolished, but a small
number do remain. For those that remain, they are vacant, underused
and most likely a brownfield. These sites have the opportunity to
be used by people again as outdoor public spaces. Pre-World War II
industrial factories hold a piece of the history of the United
States and can be given to the people once more. This report
focuses on the Carrie Furnaces, a longstanding steel production
factory in the suburbs of Pittsburgh, Pennsylvania. The site
represents Pittsburgh’s steel production era of the late 1800s and
early 1900s and has become local, national and international
artists’ inspirations since the early 1990s. After the furnaces
became a designated National Historic Landmark, a rich 20-acre
landscape is left that surrounds the beautiful industrial
architecture.
Through the use of precedent studies, interviews
and site inventory, a well-versed projective design will be
produced. This report will analyze five industrial landscape
precedents based on project scale, designer, previous use of the
site, contamination history and more. The interviews will take
place with two individuals who have worked on and with the Carrie
Furnaces for the past 20 years. This report will gear questions
towards understanding their personal experiences with the site and
their hopes for the future. A thorough site inventory and analysis
will be conducted, exploring existing conditions at the regional
and site scale. Site analysis at the site scale will include site
identity, site inventory, diagramming and opportunities, and
constraints. From utilizing these methods, a projective design can
show the future growth of the Carrie Furnaces through programmed
spaces and economic opportunities that bring the history and space
back to the people of suburban Pittsburgh.

▼ The Meramec member of Mississippian age is a
proficient oil and gas producing formation within the midcontinent
region of the United States. It is produced in
Kansas, Oklahoma,
and Texas. In
Kansas, 12% of the state’s petroleum production comes
from Mississippian-aged rocks. Bindley Field, located in central
west
Kansas, has produced 3,669,283 barrels of oil from one facies
within the M2 interval of the Meramec formation. This facies is a
grain-supported echinoderm/bryozoan dolostone, of variable
thickness. Its sporadic occurrence in the subsurface has made
exploring Bindley Field and the surrounding area difficult. The
challenge in finding oil in this area is in locating a producible
zone of this productive facies.
Previously, Bindley Field has
been the subject of detailed reservoir characterization studies
(Ebanks et al., 1977; Johnson, 1990; Johnson, 1994). These studies
helped to contribute to a better understanding of Meramecian
stratigraphy in
Kansas. The Meramec was divided into four major
depositional sequences, with some of those sequences nonexistent in
the subsurface, due to aerial exposure and erosion post-deposition.
The Meramecian units were further separated into parasequence-scale
chronostratigraphic units based on marine flooding events. The
primary producing interval in Bindley Field is the Meramec 2
interval which consists of seven lithotypes, and is recognized to
have six, meter-scale depositional cycles (Johnson, 1990). As
production from this interval increased, more information became
available about controls on reservoir quality. There are still
areas, however, where core data do not exist, and predicting the
productive facies remains challenging.
The aim of this study is
to create a workflow for evaluating the subsurface using regional
core and log data from Bindley Field to create a model of the
subsurface distribution of the reservoir facies, which could be
extended to data poor areas. Geophysical logs (neutron, gamma ray,
guard) along with an artificial neural network (ANN), was used to
create an accurate prediction of producing intervals within the
subsurface. Values are derived from wire line log data and used to
develop the ANN definition of facies distribution within Bindley
Field. The ANN model was examined for accuracy and precision using
core description and well cuttings from wells within Bindley Field
and the surrounding area. Correlations were found between the
subsurface geometry of the study area, and the production of oil
and gas within the study area. An ANN model with an accuracy of 72%
was achieved and applied to wells surrounding the Bindley Field,
where reservoir intervals have not been as extensively studied.
A
total of 87 wells in Bindley Field and the surrounding 50 square
mile area where applied to the ANN model. The model predicted that
the productive facies thickens gradually to the northwest of
Bindley Field. Cross sections as well as an isopach map were
created using the prediction data from the ANN. Finally, an
analysis for the accuracy of the ANN and the…

▼ Ultrafast lasers allow us to study molecular dynamics
on their natural timescale. The electronic dynamics can be studied
using attosecond pulses, while the vibrational and rotational
dynamics can be probed using tens of femtosecond and picosecond
laser pulses, respectively. This capability has led to a broad
understanding of the electronic dynamics in atoms and molecules as
well as vibrational and rotational dynamics of molecules, which is
one of the important goals in basic science. Moreover, it is
possible to control quantum mechanical processes using ultrafast
intense lasers.
In this thesis, we focus on a couple of
experiments. The first involves quantum control of the formation of
neutral molecular fragments while the second focuses on three-body
fragmentation of molecules employing the native-frames analysis
method, which was recently introduced by our group [J. Rajput et
al., Phys. Rev. Lett. 120, 103001 (2018)].
Experimental studies
focused on the formation of excited neutral D fragments from D2
molecules are presented. We show that by manipulating the chirp of
the intense laser pulses, i.e. the “time order” of the frequency
components within the pulse, the formation of these fragments is
controlled. To achieve this control we implement a single-prism
compressor to manipulate the chirp of the laser pulses.
Three-body
fragmentation of CO₂ resulting in C+ + O+ + O+ is also studied. We
show that if the two bonds break in a two-step process, i.e. a
sequential breakup, the pathways from which the two identical O+
fragments originate can be separated using the native-frames
analysis method. In contrast, the two O+ fragments cannot be
distinguished if the two C-O bonds break
simultaneously.

▼ Intrinsic factors impact Listeria monocytogenes growth
in ready-to-eat poultry products. Sliced deli turkey was formulated
with in-going concentrations of 1.5% NaCl or 0.75% NaCl/0.75% KCl,
0 ppm or 200 ppm NaNO[subscript]2, and using 10% or 45% pump for a
total of 8 treatments. Turkey roasts were sliced and inoculated
with a 5-strain L. monocytogenes cocktail or peptone water
(control), vacuum packaged, and stored at 4[degree]C. Treatments
were sampled on days 0, 7, 14, 21, 28, 42, 63, and 91 of storage to
determine L. monocytogenes mean log growth and aerobic plate count
(APC). The pH, water activity, residual nitrite concentration, and
percent fat, moisture, protein, and sodium were measured using
control treatments on each sampling day. There was a nitrite by day
and a percent pump by day interaction (P<0.05) for L.
monocytogenes and APC populations. Listeria monocytogenes
populations in treatments containing 200 ppm NaNO[subscript]2 were
0.70 to 2.39 log CFU/cm[superscript]2 lower compared with products
formulated with 0 ppm NaNO[subscript]2. Using 10% pump reduced L.
monocytogenes populations by 0.62 to 1.50 log CFU/cm[superscript]2
on days 7 to 28 and at day 63 compared with 45% pump treatments.
Incorporating 1.5% NaCl or 0.75% NaCl/0.75% KCl into formulations
did not affect (P>0.05) L. monocytogenes populations during
storage. On days 7 through 91, APC populations were 0.76 to 2.96
log CFU/cm[superscript]2 lower with inclusion of 200 ppm
NaNO[subscript]2 compared to 0 ppm NaNO[subscript]2. There was a
treatment by day interaction (P<0.05) for L. monocytogenes
populations and APC. The initial inoculum level of L. monocytogenes
averaged 2.21 log CFU/cm[superscript]2 and was similar (P>0.05)
for all treatments on day 0. Listeria monocytogenes populations
increased (P<0.05) from day 0 to 14 by 1.30 to 5.04 log
CFU/cm[superscript]2. Overall, L. monocytogenes populations
increased during storage and by day 91 L. monocytogenes populations
were similar regardless of NaNO[subscript]2 level used except for
treatments formulated with 0.75% NaCl/0.75% KCl and 10% pump.
Listeria monocytogenes and APC populations were influenced by
nitrite concentration and percent pump, while inclusion of NaCl or
NaCl/KCl did not affect L. monocytogenes growth during refrigerated
storage in vacuum packed sliced deli turkey.

▼ The role of first language (L1) has been controversial
in foreign language (FL) learning and teaching. This study examines
the relationship between L1 use and gender and level of education
of EFL teachers as well as gender and EFL proficiency level of
learners in an Afghan
university setting. It also investigates the
relationship between FL use and learner anxiety by learner gender
and EFL proficiency level. The study hypothesized that female FL
teachers use the L1 more than male teachers in FL classrooms.
Second, low FL proficiency learners consider L1 use as necessary in
FL classrooms. Third, low FL proficiency students experience more
anxiety with the exclusive use of FL than higher level learners.
Fourth, female learners experience more anxiety than male students
with the exclusive use of FL by learners and teachers.
Twenty EFL
teachers participated in the study by completing a 19-item
questionnaire and sixty EFL learners by completing a 27-item
questionnaire about their views towards L1/FL use and learner
anxiety. The data, analyzed through SPSS software, included
calculating frequencies and percentages, computing correlations,
and conducting independent-samples t-tests to compare the mean
difference between the variables.
The first hypothesis was not
supported as male teachers reported using the L1 more than female
teachers. The study also revealed that male teachers with BA and MA
degrees used the L1 more than female teachers with BA degrees. In
contrast, female teachers with MA degrees used the L1 more than
male teachers with BA and MA degrees and also more than female
teachers with BA degrees. The results supported hypothesis two.
More elementary learners considered the use of L1 as necessary than
intermediate and advanced students. The findings also supported
hypotheses three and four. Elementary learners as well as female
students experienced more anxiety with the exclusive use of FL than
intermediate and advanced level students and male learners. The
principal conclusion indicated a significant positive correlation
between the exclusive use of FL and learner anxiety.

foremost providing service for their veteran through the duration
of the trip. Yet, the promise of the journey is realized when the
student-guardians are able to witness the memorials through the
eyes of those who exemplified courage, fortitude, patriotism,
service, and sacrifice – flesh and blood representatives of civic
virtue. Similarly, the veterans behold the beneficiaries of their
sacrifice providing respectful service; virtuous acts voluntary,
not obligatory. Different generations of constitutional
stakeholders – those who actively preserved the republican
experiment, others preparing to be engaged participants therein –
experiencing hope for the future as well as gratitude for those who
came before.
This report includes a narrative of the inaugural
mission of
Kansas Honor Flight – Wamego High School. Using said
narrative as exemplar of following flights, the report chronicles
the creation of bridging social capital through implicit
reciprocity and the emergence of intergenerational trust-building.
The spanning of generations is discussed through the sharing of
enduring republican principles. Heroes are democratized as witness
is bore by the soldier who lived to tell the tale.
Advisors/Committee Members: Thomas Vontz.
