Reggio Emilia And The Arts Approach: Two Exceptional Examples Of Multimodal Learning In Early Years, Fadumo Aden, Evgenia Theodotou

Journal of Global Education and Research

The Reggio Emilia approach offers children a unique experience of self-exploration embedded in the arts. This has strong links with multimodal teaching and learning. This is based on the argument that they both offer children the opportunity to communicate in multimodal ways such as drawing, drama play, gestures, music and speaking whilst placing children at the centre of their learning. This paper focuses on the concept of multimodal learning and discusses the Reggio Emilia approach and the arts approach in an effort to create links with the contents of multimodal learning. Furthermore, it compares and contrasts both approaches and identifies …

Responding To Racial Incivility In Classrooms: Hospitality And Responsibility, Nathalie Piquemal, Dave Misir, Rebeca Heringer

Journal of Global Education and Research

This paper considers the relationship between education and hospitality in the specific context of moments of incivility in classrooms, with special attention to racial/white resentment. The authors reflect on the extent to which nurturing intellectual candor with interpretive charity (Callan, 2011) can be extended to incivility shaped by white resentment. They contend there is a need to approach hospitality as responsibility (Levinas, 1969, thereby suggesting conditions for student agency. The relationship between the educator as host and giver of hospitality and the students as guests and respondents is discussed (Ruitenberg, 2011b). The paper argues the role of the teacher is …

Drivers Of Ant Composition, Richness, And Trophic Guilds In Neotropical Iron Ore Cavities, Rodrigo A. Castro-Souza, Thais G. Pellegrini, Marconi Souza-Silva, Rodrigo L. Ferreira

International Journal of Speleology

Subterranean habitats may be considered limiting for animal colonization, especially for ants, due to permanent darkness and mainly because of oligotrophic conditions. While not as deep as limestone caves, iron ore caves and other subterranean habitats may be more available for colonization because of their shallower depth. We use the richness and composition of ants to assess how differences in habitat structure affect the biodiversity and ecosystem function between cavities and surrounding epigean landscapes. We predicted that the distribution of ants would be different because of the variation in habitat structure and cavity conditions may act as a filter for …

Cancer-Related Risk Behaviors And Screening Intention Among Recreational Sport Athletes, Aldenise P. Ewing

USF Tampa Graduate Theses and Dissertations

The recreational sports arena provides a venue for young adults to increase physical activity and engage in a socially supportive environment. These are both important ways to decrease the risk for chronic diseases. It is assumed that physically active individuals lead healthier lifestyles and are more attuned to their long-term health needs. Recreational sport athletes also engage in risks for adverse cancer outcomes through increased sun exposure, intake of unhealthy diets, and recreational tobacco and alcohol use. It was of interest to assess cancer-related risk factors, cancer knowledge, and theory of planned behavior constructs in this group.

This study involved …

Chemical Tools And Treatments For Neurological Disorders And Infectious Diseases, Andrea Lemus

USF Tampa Graduate Theses and Dissertations

Neurological disorders have multiple etiologies such as genetics and age. Stress related disorders are becoming more common and diagnosed more often. Mental health disorders are no longer being treated as purely psychological. Mechanisms into the underlying factors of these disorders continue to bring this area to new frontiers. Chapter 2 of this dissertation focuses on the efforts made to prove the association of the protein FKBP51 to the stress response. We synthesized and used a molecular tool to discover and prove these interactions.

The study of neurodegenerative diseases is of continued importance as the world reaches record numbers of an …

How To Use Kernel Density Estimation As A Diagnostic And Forecasting Tool For Distributed Volcanic Vents, Charles B. Connor, Laura J. Connor, Aurelie Germa, Jacob A. Richardson, Mark S. Bebbington, Elisabeth Gallant, Armando Saballos

Statistics in Volcanology

Volcanic activity often results in the formation of new volcanic vents. These new vents can create hazards in unexpected areas. Therefore, the probability of new vent formation should be assessed as part of volcanic hazard assessments. This paper describes our use of kernel density estimation (KDE) as a way to estimate the spatial density of future volcanic vents. The bivariate Gaussian kernel function is described step-by-step using pseudocode. Our computer code, written in PERL, is used to calculate the spatial density of existing vents and then create a contour map using GMT (Generic Mapping Tools). Application of this method and …

Risky Times And Spaces: Settler Colonialism And Multiplying Genocide Prevention Through A Virtual Indian Residential School, Andrew Woolford, Adam Muller, Struan Sinclair

Genocide Studies and Prevention: An International Journal

In this article, we examine how the logic of genocide prevention aligns with a settler colonial logic of elimination. We examine how the exclusion of cultural techniques of destruction from consideration contributes to the logic of elimination, and we suggest this is, in part, a structural problem built into the logic of genocide prevention. Along these lines, we interrogate linear and molar approaches to genocide prevention and propose, in addition to existing macro-level strategies, a molecular, everyday ethos of genocide prevention that is attuned to genocidal intimacies and seeks to foster anti-genocide habits and practices. In so doing, we argue …

Reconstructing Geographic And Trophic Histories Of Fish Using Bulk And Compound-Specific Stable Isotopes From Eye Lenses, Amy A. Wallace

USF Tampa Graduate Theses and Dissertations

The present research examined the viability and utility of eye lenses as a source of lifetime stable-isotope records in fish. It is presented in three sections. The first section compared bulk isotopic variation (bulk analysis) within fish eye-lenses at two temporal resolutions and compared patterns obtained from left and right eyes. The first temporal resolution was lower in an attempt to expose broad-scale isotopic changes during life while reducing effort and cost. This approach did reveal lifetime patterns, but tended to miss certain life events, particularly during early life. The second resolution was higher and provided detail that was missed …

Closing America’S Retirement Savings Gap: Nudging Small Business Owners To Adopt Workplace Retirement Plans, Peter W. Kirtland

USF Tampa Graduate Theses and Dissertations

Small businesses, with 50 or fewer employees, rarely offer workplace retirement plans. The lack of effective retirement plan options leads to employee stress, financial strain, and social instabilities. The purpose of this research is to study why small business owners make poor decisions about workplace retirement plans. The study evaluates the information supply chain and determines that financial advisors are a critical information delivery mechanism. However, they do not take the time to discuss the various retirement plan options available with the small business owners which leads to lack of plan adoption.

A Method To Analyze Similarities Of Eye Movements: A Giscience Based Spatiotemporal Approach, Mehrdad Vaziri

USF Tampa Graduate Theses and Dissertations

Similarity analysis is the subject of several studies that primarily collect, process, and analyze movement data of various types, including animals, humans, vehicles, hurricanes, and eye tracking. The movement studies often focus on characteristics of a mobile entity (moving object) over time and space. Such studies usually are interested in tracking the changes to the moving object. Therefore, the size of the object becomes irrelevant. Each mobile object is considered a moving point through time and space. The points have all two attributes in common which are locations and timestamp of those locations. Despite the similarities between the movement datasets, …

Lung Cancer Cells Survive Egfr Tki Exposure Through Upregulation Of Cholesterol Synthesis, Mark Howell

USF Tampa Graduate Theses and Dissertations

Lung cancer is the number one cause of cancer related death in both males and females. About 20% of all non-small cell lung cancer (NSCLC) patients are expected to harbor an epidermal growth factor receptor (EGFR) activating mutation. EGFR inhibitors have been shown to provide clinical benefits over chemotherapy for lung cancer patients with EGFR activating mutations. However, despite the initial clinical responses to these EGFR targeted therapies, long-term efficacy is not possible because acquired drug resistance hampers the effectiveness of these therapies. We found that a fiber inspired smart scaffold (FiSS) platform established in our laboratory allows growth of …

Construction Of G-Quadruplexes Via Self-Assembly: Enhanced Stability And Unique Properties, Ying He

USF Tampa Graduate Theses and Dissertations

This dissertation mainly contains three parts: 1) The construction of well-defined G8-octamers through the monomer conformational design. 2) The construction of cross-layer interactions in the G8-octamer for enhanced stability in H-bond competitive solvents. 3) Design and synthesis of 8-triazole guanosine with photoluminescent properties.

Through the structural conformational design, we have developed a new class of guanosine derivatives with modification on guanine (8-aryl) and ribose (2’,3’-isopropylidene). This unique design has led to the formation of the first discrete G8-octamer with structure characterized by NMR, MS and single crystal X-ray diffraction. The selectivity between monovalent (K+) and divalent cat-ions (Ba2+ and Sr2+) …

Trajectory Based Traffic Analysis And Control Utilizing Connected Autonomous Vehicles, Yu Wang

USF Tampa Graduate Theses and Dissertations

Recent scholars have developed a number of stochastic car-following models that have successfully captured driver behavior uncertainties and reproduced stochastic traffic oscillation propagation. While elegant frequency domain analytical methods are available for stability analysis of classic deterministic linear car-following models, there lacks an analytical method for quantifying the stability performance of their peer stochastic models and theoretically proving oscillation features observed in the real world. To fill this methodological gap, this study proposes a novel analytical method that measures traffic oscillation magnitudes and reveals oscillation characteristics of stochastic linear car-following models. We investigate a general class of stochastic linear car-following …

Effect Of Atypical Protein Kinase C Inhibitor (Dnda) On Cell Proliferation And Migration Of Lung Cancer Cells, Raja Reddy Bommareddy

USF Tampa Graduate Theses and Dissertations

Lung cancer is the second most common cancer, and it is the leading cause of cancer death in both men and women. Elevated levels of PKC-ι and FAK are implicated in the progression of lung cancer and involved in cell proliferation, apoptosis, cell survival, and cell migration processes. Lung cancer diagnosis typically occurs in the late stages, which limits the treatment options. Hence, there is a dire need to develop drugs that are effective and safe to treat lung cancers. We used a novel aPKC inhibitor named DNDA (3,4-amino-2,7 napthalene disulfonic acid) to study the role of atypical PKCs (aPKCs) …

Ecological Responses Of Seascape Heterogeneity, Dinorah H. Chacin

USF Tampa Graduate Theses and Dissertations

A core aim of landscape ecologists as well as conservation and management practices has been to understand how processes that structure communities vary as a function of landscape context. Landscape heterogeneity (i.e. landscape composition, configuration) and fine-scale habitat characteristics can influence ecological interactions across habitat patches at a range of scales. Therefore, the main objective of this work is to apply a landscape ecology perspective to understand how seascape heterogeneity can influence demographic rates, community patterns, and ecological processes. To accomplish this overall goal, I conducted a literature review on oyster reefs from a seascape ecology perspective (Chapter 1) and …

The Activity And Structure Of Cu2+-Biomolecules In Disease And Disease Treatment, Darrell Cole Cerrato

USF Tampa Graduate Theses and Dissertations

Despite its relatively low concentration in the human body, copper is an essential transition metal ion. Under normal circumstances, it is a well-regulated trace element that is introduced via diet or environment depending on the organism. Its strong reactivity and binding to some biologically essential chemicals can be detrimental to the host organism. Herein the oxidative chemistry of copper and its possible prevention in humans and agricultural organisms is discussed, as well as the potential avenues as metal-targeting disease treatment via novel-peptide and peptoid products.

In the first study, copper is implicated in the progression and onset of Alzheimer’s disease. …

Identifying Employees Who Fit With Electronic Communication Styles, Britany Telford Mills

USF Tampa Graduate Theses and Dissertations

Electronic communication is no longer solely used by globally dispersed work teams. It is an integral part of today’s organizations whether they include remote workers or not. Therefore, it is important to understand how employees perceive electronic communication from their supervisor and the impact that perception has on the worker. Researchers have been adamant in the assertion that relationship-oriented communicated is better conducted face-to-face. The current study seeks to add to the existing body of research by (1) examining how the proportion of relationship-oriented communication that is electronic affects both subordinate perceptions of communication openness and subordinate job satisfaction, and …

High Ammonia Strength Wastewater Treatment Using Algae, Bacteria And Ion Exchange, Nadezhda Zalivina

USF Tampa Graduate Theses and Dissertations

Nitrogen pollution has been considered one of the major problems of the 21st century. Discharge of nitrogen from improperly treated wastewaters into surface water bodies causes eutrophication and hypoxia, which results in significant environmental, public health and economic damages. In addition to the incoming flow, wastewater treatment plants generate internal highly concentrated ammonium streams, such as anaerobic digestion sidestream. As a current practice, sidestream without prior treatment is returned to the head of the plant, which increases the total incoming nitrogen load by 20-30% and often exceeds the treatment capacity. The most commonly used conventional biological nitrogen removal processes are …

Use Of Spectrofluorometry To Detect Petroleum Hydrocarbons In The Marine Environment, Mary Iris Abercrombie

USF Tampa Graduate Theses and Dissertations

The genesis of this research was the Deepwater Horizon oil spill, which discharged petroleum and gas into the Gulf of Mexico for 87 days in 2010. High-resolution fluorescence spectroscopy was employed for the detection of petroleum in seawater samples following the oil spill. Fluorescence arises from the chemical structure of π-bonding in C=C bonds, especially those in aromatic structures. Spectrofluorometry was also used to observe and track the formation of petroleum plumes in seawater undergoing controlled physical dispersion in a wave tank, both with and without the addition of chemical dispersant. Further, the changing fluorescence characteristics of a broad range …

Development Of A Voxel-Based Monte Carlo Radiation Dosimetry Methodology For A Targeted Alpha Particle Therapy, Christopher John Tichacek

USF Tampa Graduate Theses and Dissertations

The use of targeted ligands to deliver radioisotopes directly to tumor cells is a promising therapeutic strategy. Because of the short path length and high LET of alpha particles, targeted alpha particles are ideal for treating metastatic disease while minimizing damage to non-targeted tissues. However, clinical methods for determining 3D radiation dosimetry in patients with multiple metastatic lesions are needed to support clinical translation of novel targeted alpha particle therapies for personalized treatment, especially in patients that have previously received radiotherapy. Recently interest in novel radiopharmaceutical development has grown significantly. However, compared to external beam radiation therapy, progress in customizing …
