Tobacco Hornworm (Manduca Sexta) Oral Secretion Elicits Reactive Oxygen Species In Isolated Tomato Protoplasts, Akanksha Gandhi, Rupesh R. Kariyat, Cruz Chappa, Mandeep Tayal, Nirakar Sahoo

School of Integrative Biological & Chemical Sciences (Formerly Dept. of Biology)

Plants are under constant attack by a suite of insect herbivores. Over millions of years of coexistence, plants have evolved the ability to sense insect feeding via herbivore-associated elicitors in oral secretions, which can mobilize defense responses. However, herbivore-associated elicitors and the intrinsic downstream modulator of such interactions remain less understood. In this study, we show that tobacco hornworm caterpillar (Manduca sexta) oral secretion (OS) induces reactive oxygen species (ROS) in tomato (Solanum lycopersicum) protoplasts. By using a dye-based ROS imaging approach, our study shows that application of plant-fed (PF) M. sexta OS generates significantly higher ROS while artificial diet-fed …

Improving The Robustness Of The Advanced Ligo Detectors To Earthquakes, Eyal Schwartz, A. Pele, J. Warner, B. Lantz, Joseph Betzwieser, K. L. Dooley, S. Biscans, K. E. Ramirez

Physics & Astronomy Faculty Publications

Teleseismic, or distant, earthquakes regularly disrupt the operation of ground–based gravitational wave detectors such as Advanced LIGO. Here, we present EQ mode, a new global control scheme, consisting of an automated sequence of optimized control filters that reduces and coordinates the motion of the seismic isolation platforms during earthquakes. This, in turn, suppresses the differential motion of the interferometer arms with respect to one another, resulting in a reduction of DARM signal at frequencies below 100 mHz. Our method greatly improved the interferometers' capability to remain operational during earthquakes, with ground velocities up to 3.9 μm s−1 rms …

Perceptions Of K-12 Teachers On The Cognitive, Affective, And Conative Functionalities Of Gifted Students Engaged In Design Thinking, Krista M. Stith, Mistie L. Potts, Lisa Davia Rubenstein, Kathryn L. Shively, Robyn Spoon

Journal of STEM Teacher Education

Gifted students are our nation’s natural resource of technological inventors and innovators, but oftentimes do not receive differentiated instruction in technology/engineering design learning environments. This is not negligence or lack of care by the instructor, but a national issue of not sufficiently providing pre- and in-service teachers with formal training opportunities in gifted education. The purpose of this study was to understand the perceptions of K-12 teachers, trained in gifted education pedagogy and the Design Thinking Model (DTM), after their gifted students engaged in design thinking activities. Fifteen K-12 educators of different content areas reflected in focus groups upon how …

Nature Of Problem-Solving Skills For 21st Century Stem Learners: What Teachers Need To Know, Paul Nnanyereugo Iwuanyanwu

Journal of STEM Teacher Education

Since the emergence of the fourth industrial revolution which calls for a new model of learning for the twenty-first century learners, it has been argued that the nature of problems that learners must solve in science, technology, engineering and mathematics (STEM) must also be transformed to enable new forms of learning skills that are needed to tackle complex global challenges. However, the question of how best to teach these skills purposefully and explicitly is largely overlooked. STEM education reformers recognize that the lecture method or traditional method of teaching is highly ineffective for teaching twenty-first century competencies and skills that …

Integrating Literacy Into Stem Education: Changing Teachers’ Dispositions And Classroom Practice, Shoudong Feng, Umadevi Garimella, Carolyn Pinchback

Journal of STEM Teacher Education

In this paper, the results of a study of teachers’ dispositions and classroom practices regarding literacy integration into STEM courses are presented. The Connection Core Concepts (CCI) program, developed through Mathematics and Science Partnership (MSP) grant funds, was designed to support the integration of content across subject areas. Literacy is one of the emphases in Integrated STEM to enhance teacher content knowledge and increase student success. Research data were gathered from 30 teacher participants from Grades 5–8 through surveys, observations and interviews. The results indicated that there were positive changes in teacher perceptions as well as classroom practices in regard …

Classrooms As Workplace: “Early Pre-Service” Stem Teaching Experience In A University-Based Summer Stem Institute, Daniel Choi, Antoinette S. Linton

Journal of STEM Teacher Education

The focus of study is to examine the impact that The Orange County Teacher Pathway Partnership (OC-TPP) at CSU Fullerton has had on participants’ (community college transfer students) skills and experiences gained in each of the program years from years 2015-2018. Students who participated in the STEM Institute gained pre-professional skills and teaching experience through various activities in the program. Students remained on the teacher pathway because the program allowed them to break out of their comfort zones, build social connections, and adjust to various groups of people. Attending the program increased college student confidence in content knowledge and content-based …

Implementation And Sustainment Of A Statewide Telemedicine Diabetic Retinopathy Screening Network For Federally Designated Safety-Net Clinics, Ana Bastos De Carvalho, S. Lee Ware, Feitong Lei, Heather M. Bush, Robert Sprang, Eric B. Higgins

Ophthalmology and Visual Science Faculty Publications

CONTEXT: Diabetic retinopathy (DR) is the leading cause of incident blindness among working-age adults in the United States. Federally designated safety-net clinics (FDSC) often serve as point-of-contact for patients least likely to receive recommended DR screenings, creating opportunity for targeted interventions to increase screening access and compliance.

STUDY DESIGN AND METHODS: With such a goal, we implemented and assessed the longitudinal performance of an FDSC-based telemedicine DR screening (TDRS) network of 22 clinical sites providing nonmydriatic fundus photography with remote interpretation and reporting. Retrospective analysis of patient encounters between February 2014 and January 2019 was performed to assess rates of …

Using State Assessments To Increase Equity In G/T Identification, Sarah Mckenzie, Josh B. Mcgee, Charlene A. Reid, Bich Tran

Policy Briefs

In this brief, we explore the rate of identification of students as Gifted and Talented (G/T). In particular we examine the rate of identification for the highest achieving 3rd graders who scored in the top 5% statewide on state assessments in both Reading and Mathematics from 2015 to 2018 and the likelihood that they are identified G/T by 4th grade. Across five cohorts of 3rd to 4th grade students, we find that 30% of the highest achieving students are not identified as G/T. We find statistically significant differences in the likelihood that high achieving students from economically disadvantaged backgrounds are …

Supporting Our Struggling Students: Details Of A Hybrid Mathematics Summer Bridge Program, Anita White, Patrick Davis, Marti Shirley

Faculty Publications & Research

It goes without saying that the schools in the consortium are used to dealing with gifted and talented students. However with such high-caliber students, we also have high expectations. What resources do we offer to the students who struggle at our institutions? This presentation will detail the setup and results of EXCEL2 - a summer bridge program offered at the Illinois Mathematics & Science Academy to help students who were unable to meet course expectations. The program operated through a hybrid online/in-person model - with instruction primarily given through video conferencing but coupled with an on-campus experience.

Unifying Security Policy Enforcement: Theory And Practice, Shamaria Engram

USF Tampa Graduate Theses and Dissertations

Security policies stipulate restrictions on the behaviors of systems to prevent themfrom behaving in harmful ways. One way to ensure that systems satisfy the constraints of a security policy is through the use of security enforcement mechanisms. To understand the fundamental limitations of such mechanisms, formal methods are employed to prove properties and reason about their behaviors. The particular formalism employed, however, typically depends on the time at which a mechanism operates.

Mechanisms operating before a program's execution are static mechanisms, and mechanisms operating during a program's execution are dynamic mechanisms. Static mechanisms are fundamentally limited in the types of …

Discovery Of Driver Non-Coding Splice-Site-Creating Mutations In Cancer., Song Cao, Daniel Cui Zhou, Clara Oh, Reyka G Jayasinghe, Yanyan Zhao, Christopher J Yoon, Matthew A Wyczalkowski, Matthew H Bailey, Terrence Tsou, Qingsong Gao, Andrew Malone, Sheila Reynolds, Ilya Shmulevich, Michael C Wendl, Feng Chen, Li Ding

Articles, Abstracts, and Reports

Non-coding mutations can create splice sites, however the true extent of how such somatic non-coding mutations affect RNA splicing are largely unexplored. Here we use the MiSplice pipeline to analyze 783 cancer cases with WGS data and 9494 cases with WES data, discovering 562 non-coding mutations that lead to splicing alterations. Notably, most of these mutations create new exons. Introns associated with new exon creation are significantly larger than the genome-wide average intron size. We find that some mutation-induced splicing alterations are located in genes important in tumorigenesis (ATRX, BCOR, CDKN2B, MAP3K1, MAP3K4, MDM2, SMAD4, STK11, TP53 etc.), often leading …

Potential Effect Of Bio-Surfactants On Sea Spray Generation In Tropical Cyclone Conditions, Breanna L. Vanderplow, Alexander Soloviev, Cayla W. Dean, Brian K. Haus, Roger Lukas, Muhammad Sami, Isaac Ginis

Marine & Environmental Sciences Faculty Articles

Despite significant improvement in computational and observational capabilities, predicting intensity and intensification of major tropical cyclones remains a challenge. In 2017 Hurricane Maria intensified to a Category 5 storm within 24 h, devastating Puerto Rico. In 2019 Hurricane Dorian, predicted to remain tropical storm, unexpectedly intensified into a Category 5 storm and destroyed the Bahamas. The official forecast and computer models were unable to predict rapid intensification of these storms. One possible reason for this is that key physics, including microscale processes at the air-sea interface, are poorly understood and parameterized in existing forecast models. Here we show that surfactants …

Damnatio Memoriae: On Deleting The East From Western History, Koert Debeuf

New England Journal of Public Policy

The story we read in books about the Renaissance tells us that Petrarch and Poggio rediscovered the books of antiquity that had been copied for centuries in medieval abbeys. The re-introduction of Greek science and philosophy, however, began in the twelfth century but occurred mainly in the thirteenth century. These works were first translated into Syriac and Arabic in the eighth and ninth centuries and stored in the House of Wisdom in Baghdad. There they were read, used, and commented on by Arab philosophers, of whom the most famous was Averroes (1126–1198), who lived in Cordoba. The translation of his …

Understanding Myanmar’S Buddhist Extremists: Some Preliminary Musings, Kumar Ramakrishna

New England Journal of Public Policy

This article examines Buddhist extremism in Myanmar. It argues that Buddhist extremism—like other types of religious extremism—is an acute form of fundamentalism. The article begins with a survey of how extremism is usually understood in the theoretical literature, showing that its religious variant is best conceived of as an acute form of fundamentalism. It then fine tunes this understanding, arguing that religious extremism is a fundamentalist belief system that justifies structural violence against relevant out-groups. The article outlines seven core characteristics of the religious extremist culled from the various theoretical approaches to extremism. It employs these seven characteristics to examine …

What Can We Learn About Improving Gifted Identification By Studying How Accurate The Process Is In Arkansas?, Bich Tran, Jonathan Wai, Sarah C. Mckenzie, Jonathan N. Mills, Dustin Seaton

Arkansas Education Reports

How might we improve gifted and talented (G/T) identification by learning about the process in Arkansas (AR)? In this study, we examined the accuracy of the gifted identification process in AR by comparing the degree to which students who were academically talented in the top 5% on the 3 rd grade state assessment in reading and mathematics in AR were identified for G/T. Across five years of independent cohorts, we replicate the finding that roughly 30% of the students in the top 5% in both reading and mathematics on the 3 rd grade state assessment are not identified as G/T. …

Multifunctional Metal-Organic Frameworks (Mofs) For Applications In Sustainability, Gaurav Verma

USF Tampa Graduate Theses and Dissertations

Climate change, affordable and clean energy, and responsible consumption and production are some of the important goals to be achieved for sustainable development. The current technologies used to address these challenges are energy and resource intensive. Furthermore, there are various limitations related to cost, storage, scalability and safety.Adsorbent materials are seen as a promising alternative remediation system due to their low energy consumption and minimal chemical waste production. However, most of the traditional adsorbents, such as activated carbon and zeolites lack the structural tunability to have long-term effectiveness and their use is limited. As discussed in Chapter 1, metal organic-frameworks …
