Perceived Lack Of Teacher Empathy And Remedial Classroom Conflicts, Henry Young

Department of Conflict Resolution Studies Theses and Dissertations

In light of earlier research pertaining to empathy, it is reasonable to believe that certain teachers feel empathic toward students in remedial classrooms. It is also evident that teacher empathy is something that students relish. However, a perceived lack of teacher empathy among students in remedial classes is a concern. The general problem addressed in the study was the effect of teachers’ lack of empathy on remedial college students’ perceptions of teacher–student conflict. The specific problem addressed in the study was the limited research on the impact of teachers’ empathy on remedial students’ perceptions. The purposes of the study were …

Men And College Enrollment: A Grounded Theory Study On Understanding How Gender Stereotypes Influence Men And Their Decision-Making, Mark Bukowski

Department of Conflict Resolution Studies Theses and Dissertations

The male to female gender gap in higher education continues to average around 40% to 60%. This is a significant societal statistic that will continue to define generations to come and influence the demographics of the workforce and social roles. This Conflict Resolution study strove to find an answer to what are the societal influences impacting male enrollment in a community college in southwest Florida and to explore the role of conflict in prospective male students’ decision-making related to higher education. This question was broken down into sub-areas involving gender roles and society. The study was conducted using a grounded …

The “Weight” Of Socio-Economic Status, Race/Ethnicity, And Gender: A Systematic Examination Of Obesity And Its Co-Morbidities, Gabriele Ciciurkaite

Theses and Dissertations--Sociology

Although extensive research exists on the association between SES and obesity and its patterning across separate gender and racial/ethnic groups, critical gaps remain. In particular, the majority of studies on the SES-BMI association have examined it in additive models without simultaneously considering the influence of gender and race/ethnicity. An additional limitation of the current obesity scholarship concerns the lack of scholarship addressing the interplay between social factors, such as SES, race/ethnicity, gender, and proximate health risk factors, such as BMI, in shaping obesity-related chronic health outcomes, especially considering that health outcomes may vary in the extent to which they may …

This study uses longitudinal data from community college students enrolled in developmental reading classes to explore the impact of a success course on key momentum points and milestones. Working from an institutional database, a cohort of first semester students (N = 1,427) from a public community college in New England was tracked from fall 2007 through spring 2013. Developmental reading students enrolled in a newly-instituted success course (N = 359) were compared to peers who did not enroll in the course. Chi square analyses addressed the relationship between reading level and success course enrollment and between success course enrollment and …

Water Radiolysis And Chemical Production Rates Near Solid-Water Boundaries, Mary Elizabeth Dzaugis

Open Access Dissertations

Water radiolysis is the dissociation of water molecules by ionizing radiation from the decay of radionuclides. Primary products of water radiolysis include reactive chemicals, such as H₂ and H₂O₂. For this reason, radiolysis is studied in many domains, including nuclear waste, microbiology and planetary evolution. In order to understand the importance of radiolysis in many of these environments, accurate quantification of radiolytic production rates is vital. In this dissertation, I present a new quantitative model calculating radiolytic production rates at solid-water interfaces and apply it to understand the role that radiolysis plays in various environments. …

System Genetic Analysis Of Mechanisms Underlying Excessive Alcohol Consumption, Maren L. Smith

Theses and Dissertations

Increased alcohol consumption over time is one of the characteristic symptoms of Alcohol Use Disorder (AUD). The molecular mechanisms underlying this escalation in intake is still the subject of study. However, the mesocortical and mesolimbic dopamine pathways, and the extended amygdala, because of their involvement in reward and reinforcement are believed to play key roles in these behavioral changes. Multiple gene expression studies have shown that alcohol affects the expression of thousands of genes in the brain. The studies discussed in this document use the systems biology technique of co-expression network analysis to attempt to find

patterns within genome-wide expression …

A Pipeline For Creation Of Genome-Scale Metabolic Reconstructions, Shaun W. Norris

Theses and Dissertations

The decreasing costs of next generation sequencing technologies and the increasing speeds at which they work have lead to an abundance of 'omic datasets. The need for tools and methods to analyze, annotate, and model these datasets to better understand biological systems is growing. Here we present a novel software pipeline to reconstruct the metabolic model of an organism in silico starting from its genome sequence and a novel compilation of biological databases to better serve the generation of metabolic models. We validate these methods using five Gardnerella vaginalis strains and compare the gene annotation results to NCBI and the …

Kinematic equations are derived and implemented in Simulink to observe the theoretical working principle of the robot. A proportional controller is designed to control the motion of the robot, which is later implemented on a physical robot. Combination of linear velocity and orientation generates individual wheel velocities which are sent to the robot by wireless communication for its motion. …

Computer Modeling Of A Solar Thermal System For Space Heating, Dhananjay D. Deshpande

Browse all Theses and Dissertations

Most applications of flat plate, low-temperature solar thermal panels are for water heating, such as producing domestic hot water or raising the temperature of swimming pools. This is reasonable given that the large masses of water present in these systems inherently provide built-in thermal energy storage so that a separate energy storage tank does not have to be purchased. For a space heating system, extra thermal energy storage generally has to be purchased and is a detriment to the economics of these systems. Despite the economic drawbacks of solar thermal space heating, this thesis focuses on the size of thermal …

Design And Application Of Facile Routes To N-Heterocycle Functionalized Poly(Arylene Ether)S, Abraham K. Kemboi

Browse all Theses and Dissertations

A series of 3,5-difluorinated systems, which are activated towards nucleophilic aromatic substitution (NAS) by the strongly electron withdrawing benzoxazole or benzothiazole groups, located meta to the fluorines were prepared and fully characterized. The monomers also carry various N-heterocyclic species on the non-fluorinated ring. The corresponding poly(arylene ether)s, some of which were copolymers with triphenylphosphine oxide-based monomers, were prepared via standard NAS polycondensation reactions. Incorporation of the monomers containing N-heterocycle units was determined by NMR spectroscopy. Characterization of the thermal properties was done using thermogravimetric analysis (TGA) and differential scanning (DSC). Most of the polymers displayed good film forming properties when …

Reflective Journaling: Fostering Dispositional Development In Preservice Teachers, Jeffrey Labelle, Gabrielle Belknap

College of Education Faculty Research and Publications

This study investigated the self-identified dispositions of 183 preservice teachers enrolled in a required philosophy of education course. The researchers coded their reflective journaling for the two essential NCATE (National Council for Accreditation of Teacher Education) dispositions of fairness and the belief that all students can learn, as well as for other recurring, self-identified dispositions. These preservice teachers self-identified fairness much more frequently than the belief that all students can learn. The results point to additional recurring dispositional themes for consideration: critical thinking, caring, openness, moral education, and individual freedom. Further examination of the data revealed great variation in the …

Oxidative Durability Of Tbcs On Ti2Alc Max Phase Substrates, James L. Smialek, Bryan J. Harder, Anita Garg

United States National Aeronautics and Space Administration: Publications

Air plasma spray (APS) and plasma-spray-physical vapor deposition (PS-PVD) yttria-stabilized zirconia (YSZ) thermal barrier coatings (TBC), ~80–100 μm thick, were produced on a commercial Ti₂AlC MAX phase compound. They were oxidized in interrupted furnace tests for 500 h each, at five successive temperatures from 1100°–1300 °C. The APS coating survived 2400 accumulated hours, failing catastrophically after 500 h at 1300°C. Porosity, large cracks, sintering, and high monoclinic YSZ phase contents were seen as primary degradation factors. The PS-PVD coating remained completely intact over 2500 total hours (65 cycles) including 500 h at 1300 °C, exhibiting only fine porosity …

Mixed Modulation For Remote Sensing With Embedded Navigation, Michael J. Nowak

Browse all Theses and Dissertations

As electromagnetic spectrum availability shrinks, there is growing interest in combining multiple functions, such as radar and communications signals, into a single multipurpose waveform. Historically mixed-modulation has used orthogonal separation of different message signals in different dimensions such as time or frequency. This research explores an alternative approach of implementing an in-band, mixed-modulated waveform that combines surveillance radar and navigation functions into a single signal and demonstrates the feasibility of this approach for a limited area navigation solution. The first contribution of this research is the use of reduced phase-angle binary phase shift keying (BPSK) along with overlapped (channelized) spread-spectrum …

Can Best Practices In Writing Instruction And Standardized Testing Coexist?, Karen Cannavino

Electronic Theses and Dissertations

At the high school level, teachers are tasked with a twofold agenda: they must prepare their students for college level and other post-secondary writing, and they must also make sure they perform well on the standardized writing tests that are required by the state. The stakes in standardized testing continue to rise, especially in Florida. Since the passing of the No Child Left Behind Act in 2002 (NCLB) and the implementation of the Race to the Top Assessment Program (RTTT) in 2009, teachers across the nation have experienced intense pressures related to standardized testing. Many schools' efforts to conform to …

Changes In State Suspicion Across Time: An Examination Of Dynamic Effects, Steve Khazon

Browse all Theses and Dissertations

State Information Technology (IT) suspicion is the simultaneous action of uncertainty, mal-intent, and cognitive activity about underlying information that is being electronically generated, collated, sent, analyzed, or implemented by an external agent (Bobko, Barelka, & Hirshfield, 2014). Understanding IT suspicion is important in both military and civilian contexts as both are growing increasingly reliant on automation to augment human performance (e.g., Lenhart, Purcell, Smith, & Zickuhr, 2010). The current process model of state IT suspicion describes how suspicion arises and its immediate correlates. Little is known about how suspicion changes over time and what factors influence this change. Drawing upon …

Convergent Evolution In Tooth Morphology Of Filter Feeding Lamniform Sharks, Michaela Grace Mitchell

Browse all Theses and Dissertations

The basking shark (Cetorhinus maximus) and megamouth shark (Megachasma pelagios) are two species of filter feeding sharks, both belonging to the order Lamniformes. There are two conflicting hypotheses regarding the origins of filter feeding in Lamniform sharks; that there is a single origin of filter feeding within Lamniformes, or conversely, the filter feeding adaptations have been developed independently due to different ancestral conditions. Evidence obtained from several studies strongly supports the latter hypothesis. Because evidence suggests that C. maximus and M. pelagios have developed their filter feeding adaptations independently, we expect to see convergent evolution taking place within these two …

Measures Of User Interactions, Conversations, And Attacks In A Crowdsourced Platform Offering Emotional Support., Samir Yelne

Browse all Theses and Dissertations

Online social systems have emerged as a popular medium for people in society to communicate with each other. Among the most important reasons why people communicate is to share emotional problems, but most online social systems are uncomfortable or unsafe spaces for this purpose. This has led to the rise of online emotional support systems, where users needing to speak to someone can anonymously connect to a crowd of trained listeners for a one-on-one conversation. To better understand who, how and when users utilize these systems, and to evaluate their safety, this thesis offers a comprehensive examination of the characteristics …

Surface Effect Of Ferromagnetic Nanoparticles On Transition Between Single- And Multi-Domain Structure Or Between Single-Domain Structure And Superparamagnetic Phase, Hind Adawi

Browse all Theses and Dissertations

Surface effects on critical dimensions of ferromagnetic nanoparticles were studied. Algebraic equations were derived and numerically solved for critical radius RC2 of ferromagnetic nanoparticles describing the transition between single- and multi-domain magnetic structure. Results were analyzed to illustrate the effect of surface parameters related to saturation magnetization a, exchange interaction ß, and anisotropy KS on the critical radius of nanoparticles with a core value of anisotropy KV. Available experimental data for MnBi, FePt, and CoPt or for Fe nanoparticles were used as examples of nanoparticles with high and low values of KV, respectively. Our studies clearly show that discrepancies existing …

Spatial Variation In Tooth Shape Of Miocene Populations Of Carcharocles Megalodon Across Ocean Basins, Maxwell John Bertsos

Browse all Theses and Dissertations

The extinct Lamniform species, Carcharocles megalodon, were some of the most geographically widespread apex predators in the fossil record. However, whether this cosmopolitan distribution was related to population level differences is unknown. The objective of this study is to assess whether variation in tooth morphology coincided with geographic dispersal. The underlying hypothesis is that variation in an aspect of functional morphology, such as tooth shape, suggests some level of population structuring. Detecting this relationship could potentially provide a mechanism that links population to functional relationships inherent in tooth morphology that may reflect period differences in ocean basins. This would offer …

Synthesis And Characterization Of Peek Analogues Utilizing 3,5- And 2,4-Difluorobenzophenone., Zachary Ewing

Browse all Theses and Dissertations

Two routes to semi-crystalline, potentially functionalizable poly(ether ether ketone), PEEK, analogues were explored using varying percentages of 4,4’-difluorobenzophenone and either 3,5-difluorobenzophenone or 2,4-difluorobenzophenone as the electrophilic component in nucleophilic aromatic substitution polycondensation reactions with hydroquinone. PEEK analogues utilizing 3,5-difluorobenzophenone were carried out in a “one-pot” fashion and their properties were compared to the same materials prepared previously by a multi-step synthetic procedure. The use of 2,4-difluorobenzophenone led to completely new PEEK analogues. The polymers were characterized via NMR spectroscopy, Size Exclusion Chromatography, Thermogravimetic Analysis, and Differential Scanning Calorimetry. Molecular weight determinations showed the synthesized polymers to be of a variety …

Leadership Education: A Pilot Study Investigating Employer And Student Perceptions Of Value, Jason Scott Farkas

Browse all Theses and Dissertations

This study examined employer and student perceptions of leadership education, specifically as these perceptions relate to value, or usefulness. As post-baccalaureate leadership certification programs are increasingly added to college and university curricula, it is important to understand if these programs are imparting knowledge and skills that are observable and valuable in the workplace. Employer and student perceptions were collected through pilot focus groups and qualitatively evaluated against Kouzes and Posner's Five Practices of Exemplary Leadership, a framework that is both teachable and measurable. Suggestions for future graduate-level leadership certification programs will be discussed.

Power Distribution And Probabilistic Forecasting Of Economic Loss And Fatalities Due To Hurricanes, Earthquakes, Tornadoes, And Floods In The United States, Scott Edward Baker

Browse all Theses and Dissertations

Traditionally, the size of natural disaster events such as hurricanes, earthquakes, tornadoes, and floods is measured in terms of wind speed (m/sec), energy released (ergs), or discharge (m3/sec). Economic loss and fatalities from natural disasters result from the intersection of the human infrastructure and population with the natural event. This study investigates the size versus cumulative number distribution of individual natural disaster events in the United States. Economic losses are adjusted for inflation to 2014 United States Dollars (USD). The cumulative number divided by the time over which the data ranges is the basis for making probabilistic forecasts in terms …

Software defined networking (SDN), a new networking paradigm that separates the network data plane from the control plane, has been considered as a flexible, layered, modular, and efficient approach to managing and controlling networks ranging from wired, infrastructure-based wireless (e.g., cellular wireless networks, WiFi, wireless mesh net- works), to infrastructure-less wireless networks (e.g. mobile ad-hoc networks, vehicular ad-hoc networks) as well as to offering new types of services and to evolving the Internet architecture. Most work has focused on the SDN application in traditional and wired and/or infrastructure based networks. Wireless networks have become increasingly more heterogeneous. Secure and collab- …

Mechanisms Of Antixenosis And Antibiosis Of Ash Against Emerald Ash Borer, Chad Michael Rigsby

Browse all Theses and Dissertations

Emerald ash borer (EAB), Agrilus planipennis (Coleoptera: Buprestidae), is an invasive forest pest causing widespread mortality of ash (Fraxinus spp.) in North America. Host resistance research and the development of resistant hosts offers a promising strategy for the long-term conservation of ash and management of EAB. Manchurian ash (F. mandshurica) shares an evolutionary history with EAB in Asia, resulting in its greater resistance relative to naive North American ashes. In the following studies I investigate antixenosis and antibiosis mechanisms of resistant and susceptible ashes. Antixenosis in Manchurian ash was demonstrated by quantifying substantially lower oviposition on this species relative to …
