Title: American national identity and discourses of the frontier in early 20th century visual culture.
Creator: Maldonado, Chandra Ann, Trapani, William, Florida Atlantic University, Dorothy F. Schmidt College of Arts and Letters, School of Communication and Multimedia Studies
Abstract/Description: This thesis examines the rise of image culture in the 1920’s and its impact on American national identity. I demonstrate that, perhaps surprisingly, the central figure in these debates was not a past or present prominent American but instead an indeterminate Other which is read in ambivalent ways and for varied purposes. It is the central claim of this project that in order to trace the modern American subject that emerges from the 1920s national rift, one must attend to the ways in which a...
Show moreThis thesis examines the rise of image culture in the 1920’s and its impact on American national identity. I demonstrate that, perhaps surprisingly, the central figure in these debates was not a past or present prominent American but instead an indeterminate Other which is read in ambivalent ways and for varied purposes. It is the central claim of this project that in order to trace the modern American subject that emerges from the 1920s national rift, one must attend to the ways in which a felt need to view and position oneself in relation to “the Other” was essential to defining the nature and future of the nation. More specifically, I argue that the film Grass: A Nation’s Battle for Life (1925) offers a solution to this national divide by providing viewers a popular culture form of “evidence” of the Westerner’s capacity to exhibit both premodern and modern qualities.

Show moreAtlantic spotted dolphins (Stenella frontalis) and bottlenose dolphins (Tursiops truncatus) are two sympatric species resident to the Bahamas. The visibility of the Bahamian water provided a unique opportunity to study spotted dolphin communication during aggression. This study’s main focus was to decipher any similarities or differences in the behaviors used by spotted dolphins during interspecific and intraspecific aggression. Both similarities and differences were discovered. Biting, following, and chasing behavioral events were used more during interspecific aggression, while the display behavioral class was used more than the contact behavioral class during intrabut not interspecific aggression. This study showed that spotted dolphins use more energy intensive and risky behaviors when fighting interspecifically. This could result from having to fight and defend females from a larger species, trying to avoid sexual harassment from bottlenose males, or needing to use behaviors that are more overt and easily understood during interspecies communication.

The main contribution of this dissertation is a set of new results regarding factorization of groups, with emphasis on the nonabelian case. We introduce a novel technique for factorization of groups, the so-called free mappings, a powerful tool for factorization of a wide class of abelian and non-abelian groups. By applying a certain group action on the blocks of a factorization, a number of combinatorial and computational problems were noted and studied. In particular, we analyze the case of the group Aut(Zn) acting on blocks of factorization of Zn. We present new theoretical facts that reveal the numerical structure of the stabilizer of a set in Zn, under the action of Aut(Zn). New algorithms for finding the stabilizer of a set and checking whether two sets belong to the same orbit are proposed.

The Msr (MsrA and MsrB) family of enzymes have been studied extensively for their biological roles in reducing oxidized Met residues back into functional Met. A wide range of studies have focused on Msr both in vivo and in vitro using a variety of model organisms. More specifically, studies have noted numerous processes affected by the overexpression, under expression, and silencing of MsrA and MsrB. Collectively, the results of these studies have shown that Msr is involved in lifespan and the management of oxidative stress. More recent evidence is emerging that supports existing biological functions of Msr and theorizes the involvement of Msr in numerous biological pathways.

Show moreMy thesis exhibition will manifest a visual language I developed to express things I sense but cannot explain. I will create a sacred space, people by paper silhouettes, to communicate what it feels like to be alive while acknowledging different realities. Each silhouette figure I make has its own character and expresses specific things, including care, confusion, excitement, play, and wonder. These are all facets of my own experiences in life. The white silhouettes are anchored to a physical reality. The chromatic silhouettes are complicated by color. They are more difficult to make out – they are more vulnerable and ambiguous. I am peopling the installation with many silhouettes. This expresses the range of experiences I have had with people, as well as the many possibilities that exist for human interaction. I will create a translucent cylindrical environment that is specifically lit, with two layers of fabric. I will embed over two thousand hand-cut paper figures within this environment. One plane will represent the physical world that we all access and experience via our five senses. The other plane will express another realm – one that references spiritual or otherwise non-physical realities. In addition, I will exhibit a series of framed collages and a compilation of video clips that have informed the development and process of my work.

Show moreAlzheimer’s disease (AD) has been defined as a type of dementia that causes problems with memory, thinking, and behavior. AD is characterized by tau tangles and Aβ plaques in and around neurons, respectively. The impact this disease has on its victims’ health, both physically and mentally, is unimaginable and the rate of progression is not expected to decrease any time soon. This threat to our minds encourages the importance of understanding AD. Amongst the theories as to what bio mechanisms cause the brain to intertwine is the amyloid cascade hypothesis. The purpose of this thesis is to review the amyloid cascade hypothesis and discuss treatments which utilize this model. We also wish to examine social aspects such as loneliness and socioeconomic factors which are associated with the progression of AD. Research presented provides evidence that targeting the accumulation of Aβ in the brain will prevent further biochemical responses to form neurodegenerative pathology. From the collected data, we observe that therapies targeting the amyloidogenic pathway have received positive feedback in the medical community. Amongst them, an Aβ synthetic peptide vaccine which made history in vaccine development due to their responder rate. The impact of social factors such as loneliness in the advancement of AD is also supported by research. While it is acknowledged that any neurodegenerative disease is far too complex to narrow its cause specifically, this thesis provides an association with multiple aspects that can be understood and applied to future research in this field.

Show moreAccording to Molnar (2014), full time virtual school education lacks a measurement tool that accurately measures effective virtual teacher practice. Using both qualitative and quantitative methods, the current study sought to understand the common practices among full time K-8 virtual school teachers, the extent to which teachers believed such practices impacted student learning, as well as the methods in which current standards, recommendations and practices were implemented in the full time K-8 virtual school setting. The relationship between virtual school teacher practices and their Technological Pedagogical and Content Knowledge (TPACK) was also explored. Using the standards, practices and recommendations developed for online learning from International Association for K–12 Online Learning (iNACOL), National Education Association (NEA), Southern Regional Education Board (SREB), and the International Society for Technology in Education (ISTE) a team of focus group members gave input on the common practices for teaching students in the full time K-8 virtual school environment. The results included 11 general virtual school teacher practices, 12 teacher practices relating to evaluation and three practices relating to special needs and diverse learners. Qualitative and quantitative findings indicated that teachers most frequently meet the established practices through the following strategies: phone conferences, live sessions with students, feedback on assessments, webmail communication, professional development, collaborating with peers/teacher collaboration, professional learning communities, curriculum based assessments on the phone, communicating with family stakeholders, and determining students in the bottom quartile. A framework for K-8 full time virtual school pedagogy which includes evaluating student learning and individualizing instruction through technology tools and collaborative methods was developed. Finally, the quantitative findings indicated that of the three virtual school teacher practice categories (teacher practice, evaluation and special needs and diverse learners), evaluation was the leading predictor of teacher TPACK scores. Specifically, collaboration, having an online voice and presence, and using data from assessments to modify instruction were found to significantly predict a teacher’s Technological Pedagogical and Content Knowledge. Using virtual school teachers’ expertise on the practices which most impact student learning and the methods for implementing virtual school teacher practices, the researcher created a draft full time K-8 virtual school teacher evaluation rubric.

Relevant efforts in general, entail the task of quantitatively estimating the details about the likelihood of future events (or unknown outcomes/effects) based on past and current information on the observed events (or known causes). Commensurate with the scope and objectives of the research, the specific topics addressed are as follows: A review on various methods adopted in technoeconomic forecasting and identified are econometric projections that can be used for forecasting via artificial neural network (ANN)-based simulations Developing and testing a compatible version of ANN designed to support a dynamic sigmoidal (squashing) function that morphs to the stochastical trends of the ANN input. As such, the network architecture gets pruned for reduced complexity across the span of iterative training schedule leading to the realization of a constructive artificial neural-network (CANN). Formulating a training schedule on an ANN with sparsely-sampled data via sparsity removal with cardinality enhancement procedure (through Nyquist sampling) and invoking statistical bootstrapping technique of resampling applied on the cardinality-improved subset so as to obtain an enhanced number of pseudoreplicates required as an adequate ensemble for robust training of the test ANN: The training and prediction exercises on the test ANN corresponds to optimally elucidating output predictions in the context of the technoeconomics framework of the power generation considered Prescribing a cone-of-error to alleviate over- or under-predictions toward prudently interpreting the results obtained; and, squeezing the cone-of-error to get a final cone-of-forecast rendering the forecast estimation/inference to be more precise Designing an ANN-based fuzzy inference engine (FIE) to ascertain the ex ante forecast details based on sparse sets of ex post data gathered in technoeconomic contexts - Involved thereof a novel method of .fusing fuzzy considerations and data sparsity.Lastly, summarizing the results with essential conclusions and identifying possible research items for future efforts identified as open-questions.

Title: Are Women Moving? Food Insecurity, Obesity, and Women’s Food-Access Strategies in Broward County Florida’s Food Deserts.

Show moreFood insecurity or low-access to good quality, affordable foods affects minority women and children disproportionately (Herndon, 2014; Ivers & Cullen, 2011; Lee, 2012; Wigg Dammann & Smith, 2009). Linked to the rise in nutritionrelated and other health problems afflicting these populations (e.g., malnutrition, obesity, diabetes and high blood pressure among others) (Azarbad & Gonder- Frederick, 2010; Bove & Olson, 2006; Larson, Story, & Nelson, 2009), this issue has been gaining some attention. Still, programs combating weight and “weightrelated disorders” generally focus on individualistic solutions (Orbach, Bodies 2009)—such as increasing daily exercise and vilifying certain diets. Dismissing important spatial and systematic aspects, these approaches rather perpetuate problematic socio-political, economic, medical, and ideological biases informing our understanding of poverty, health and food. This project offers and alternative perspective. Most importantly, it 1) scrutinizes sexist, classist and racist constructs across the literature on overweight, obesity, poverty, and health; 2) examines the relationship between our food system, the growth in nutrition-related diseases, and the intersections of gender, race, and class within food insecure communities; and 3) analyzes interview data looking for important and resonating themes that could guide the development of more efficient local food access strategies. As this study shows, these women’s experiences, knowledge, and strategies have the potential of, not only helping eradicate food insecurity across South Florida, but also combating a great number of the nutrition-related health problems afflicting these populations.

Mainly consisting of drawn dried flower forms and expressive female hands, these elements come together in deliberate arrangements of spaces and relations. The moments of sensuality resulting from these exploratory touches signify moments created through traversing bodies and identities. To achieve this exploration visually, I created a collection of eight drawing collages and a large paper installation with mixed media components. The elements in this work are carefully placed in relation to one another with the intent of constructing an abstract narrative exploring the who, how, and the why of the self—specifically the queer self and the search for belonging that accompanies the discovery of this identity.

Show moreEstimating the sex of unknown human skeletal remains is important to the fields of forensic anthropology, bioarchaeology, and other specialties. I studied sexual dimorphism on the first and second ribs to estimate sex from skeletal remains. I employed two approaches. I used geometric morphometrics to analyze landmark and semilandmark coordinate points to examine the overall shape of the ribs. I also examined the sternal end of the ribs for size using the superior-inferior height (SIH) and anteriorposterior breadth (APB) in a binary logistic regression (BLR) model. Differences in male and female first and second ribs are undetectable when landmark coordinate points are used to capture shape variability, but significant differences in the shape of the ribs, however, are detected through the use of semilandmark coordinate points. Using semilandmark points to estimate sex presented an accuracy rate of 80.7% from the first rib, and 72.9% from the second rib. The use of the sternal end presents consistent results in its ability to estimate sex with an accuracy rate of 84.2%. The BLR model reveals significant differences between males and females than the geometric morphometric approach; it is more applicable for discerning sexual dimorphism of unknown individuals. This study reveals that while geometric morphometrics provides a powerful approach to assessing morphological differences, it is not always better than simpler methods, in this case, simple measurements analyzed through BLR.

Show moreStudies exploring facial emotion recognition (FER) abilities in autism spectrum disorder (ASD) samples have yielded inconsistent results despite the widely-accepted finding that an impairment in emotion recognition is a core component of ASD. The current study aimed to determine if an FER task featuring both unfamiliar and familiar faces would highlight additional group differences between ASD children and typically developing (TD) children. We tested the two groups of 4- to 8-year-olds on this revised task, and also compared their resting-state brain activity using electroencephalogram (EEG) measurements. As hypothesized, the TD group had significantly higher overall emotion recognition percent scores. In addition, there was a significant interaction effect of group by familiarity, with the ASD group recognizing emotional expressions significantly better in familiar faces than in unfamiliar ones. This finding may be related to the preference of children with autism for people and situations which they are accustomed to. TD children did not demonstrate this pattern, as their recognition scores were approximately the same for familiar faces and unfamiliar ones. No significant group differences existed for EEG alpha power or EEG alpha asymmetry in frontal, central, temporal, parietal, or occipital brain regions. Also, neither of these EEG measurements were strongly correlated with the group FER performances. Further evidence is needed to assess the association between neurophysiological measurements and behavioral symptoms of ASD. The behavioral results of this study provide preliminary evidence that an FER task featuring both familiar and unfamiliar expressions produces a more optimal assessment of emotion recognition ability.

Individual and coupled effects of inter-annual ENSO, decadal PDO, multi-decadal AMO, and quasi-decadal NAO on sea levels are evaluated. Combined influences of different phases (cool or warm) of PDO, AMO, and NAO influences and ENSO are also evaluated. The results from this study showed that sea level at 60% of the sites is increasing with time with all four oscillations impacting global sea levels. AMO warm phase individually and PDO warm combined with La-Niña phase contribute to higher sea levels throughout the world. Trends and variations in sea levels are noted to be spatially non-uniform. Understanding and quantifying climate variability influenced variations in sea levels and assessment of long-term trends enables protection of coastal regions of the world from sea level rise.

Abstract/Description: Most U.S. urban traffic signal systems deploy multiple signal timing plans to account for daily variability of traffic demand (i.e. morning peak, midday, afternoon peak, off peak and night). Groups of signals (belonging to the one zone or section) along an urban arterial, usually operate in a coordinated manner. This essentially means that timing plans change at the same time for all the signals in the group, so as to facilitate vehicle progression of through a series of signals. Good traffic...

Groups of signals (belonging to the one zone or section) along an urban arterial, usually operate in a coordinated manner. This essentially means that timing plans change at the same time for all the signals in the group, so as to facilitate vehicle progression of through a series of signals. Good traffic signal timing practices assume a certain level of monitoring and maintenance in order to guarantee that they are efficient in servicing current traffic conditions.

Title: Assessment of Changes in Precipitation Data Characteristics due to Infilling by Spatially Interpolated Estimates.
Creator: Hachmi, Mohammad, Teegavarapu, Ramesh, Florida Atlantic University, College of Engineering and Computer Science, Department of Civil, Environmental and Geomatics Engineering
Abstract/Description: Spatial and temporal interpolation methods are commonly used methods for estimating missing precipitation rain gauge data based on values recorded at neighboring gauges. However, these interpolation methods have not been comprehensively checked for their ability to preserve time series characteristics. Assessing the preservation of time series characteristics helps achieving a threshold criteria of length of gaps in a data set that is acceptable to be filled. This study evaluates the efficacy...
Show moreSpatial and temporal interpolation methods are commonly used methods for estimating missing precipitation rain gauge data based on values recorded at neighboring gauges. However, these interpolation methods have not been comprehensively checked for their ability to preserve time series characteristics. Assessing the preservation of time series characteristics helps achieving a threshold criteria of length of gaps in a data set that is acceptable to be filled. This study evaluates the efficacy of optimal weighting interpolation for estimation of missing data in preserving time series characteristics. Rain gauges in the state of Kentucky are used as a case study. Several model performance measures are also evaluated to validate the filling model; followed by time series characteristics to evaluate the accuracy of estimation and preservation of precipitation data characteristics. This study resulted in a definition of region-specific threshold of the maximum length of gaps allowed in a data set at five percent.

Title: Assessment of Accuracy of Intra-Set Rating of Perceived Exertion in the Squat, Bench Press, and Deadlift.
Creator: Sousa, Colbey A., Zourdos, Michael C., Florida Atlantic University, College of Education, Department of Exercise Science and Health Promotion
Abstract/Description: The purpose of this research was to investigate how accurate trained lifters were at gauging intra-set rating of Perceived Exertion (RPE) in the squat, bench press, and deadlift. Ten resistance-trained males completed four sets to failure with 80% of their one-repetition maximum (1RM) and verbally indicated when they believed they were at a “6” and “9” RPE. Across all sets and all lifts, the called 9 RPE was more accurate than the called 6 RPE. Additionally, RPE calls were more accurate...

Ten resistance-trained males completed four sets to failure with 80% of their one-repetition maximum (1RM) and verbally indicated when they believed they were at a “6” and “9” RPE. Across all sets and all lifts, the called 9 RPE was more accurate than the called 6 RPE. Additionally, RPE calls were more accurate during set four vs. set one on the squat and deadlift at both the called 6 and 9 RPEs. Further bench press RPE calls were more accurate than squat and deadlift RPE at the called 6, while both bench and deadlift RPE calls were more accurate than squat RPEs at the called 9. Importantly across all sets all RPE calls assessed repetitions in reserve within one repetition of precision.

Title: Between Rock Cairns And Charm Stones: An Examination Of Women’s Access To Healing Roles In California Hunter-Gatherer Groups.
Creator: Hampton, Ashley, Brown, Susan Love, Florida Atlantic University, Dorothy F. Schmidt College of Arts and Letters, Department of Anthropology
Abstract/Description: The purpose of this study is to evaluate the validity of previous theories concerning women’s access to roles of power within hunter-gatherer societies. This study examines how accurately immanent social identity theory and bifurcated role circumstantiality predict women’s access to the role of healer (shaman) within California hunter-gatherer groups. A sample of 27 California hunter-gatherer groups was analyzed using both qualitative and quantitative methods. Notably, chi-square tests of...
Show moreThe purpose of this study is to evaluate the validity of previous theories concerning women’s access to roles of power within hunter-gatherer societies. This study examines how accurately immanent social identity theory and bifurcated role circumstantiality predict women’s access to the role of healer (shaman) within California hunter-gatherer groups. A sample of 27 California hunter-gatherer groups was analyzed using both qualitative and quantitative methods. Notably, chi-square tests of independence evinced a correlation between men’s and women’s circumstantial labor and observed healer gender. Through the statistical verification of such engendered ideas, this study tests notions concerning the strict binary division of labor and posits that gender may have operated as a role-based identity marker rather than one structured around innate characteristics. This research ultimately provides a better analytical framework from which archaeologists can interpret the past through the use of ethnographic analogies that are more inclusive of gender-enriched methodologies.
