Assessment Of The Presence And Strength Of H-Bonds By Means Of Corrected Nmr, Steve Scheiner

Chemistry and Biochemistry Faculty Publications

The downfield shift of the NMR signal of the bridging proton in a H-bond (HB) is composed of two elements. The formation of the HB causes charge transfer and polarization that lead to a deshielding. A second factor is the mere presence of the proton-accepting group, whose electron density and response to an external magnetic field induce effects at the position of the bridging proton, exclusive of any H-bonding phenomenon. This second positional shielding must be subtracted from the full observed shift in order to assess the deshielding of the proton caused purely by HB formation. This concept is applied …

Infrared Spectroscopy Of The Nitrogenase Mofe Protein Under Electrochemical Control: Potential-Triggered Co Binding, P. Paengnakorn, Philip A. Ash, Sudipta K. Shaw, Karamatullah Danyal, T. Chen, Dennis R. Dean, Lance C. Seefeldt, Kylie A. Vincent

Chemistry and Biochemistry Faculty Publications

We demonstrate electrochemical control of the nitrogenase MoFe protein, in the absence of Fe protein or ATP, using europium(III/II) polyaminocarboxylate complexes as electron transfer mediators. This allows the potential dependence of proton reduction and inhibitor (CO) binding to the active site FeMo-cofactor to be established. Reduction of protons to H2 is catalyzed by the wild type MoFe protein and Β-98^Tyr→His and Β-^99Phe→His variants of the MoFe protein at potentials more negative than -800 mV (vs. SHE), with greater electrocatalytic proton reduction rates observed for the variants compared to the wild type protein. Electrocatalytic proton reduction is strongly …

Scalable Clustering Using The Dempster-Shafer Theory Of Evidence, Alireza Chakeri

USF Tampa Graduate Theses and Dissertations

Clustering large data sets has become very important as the amount of available unlabeled data increases. Single Pass Fuzzy C-Means (SPFCM) is useful when memory is too limited to load the whole data set. The main idea is to divide dataset into several chunks and to apply fuzzy c-means (FCM) to each chunk. SPFCM uses the weighted cluster centers of the previous chunk in the next data chunks. However, when the number of chunks is increased, the algorithm shows sensitivity to the order in which the data is processed. Hence, we improved SPFCM by recognizing boundary and noisy data in …

Systems Thinking In The Forest Service: A Framework To Guide Practical Application For Social-Ecological Management In The Enterprise Program, Megan Kathleen Kmon

Dissertations and Theses

The U.S. Forest Service (USFS) Enterprise Program (EP), which provides fee-for-service consulting services to the USFS, is interested in integrating systems thinking into its service offerings. Despite there being several excellent sources on the range and diversity of systems thinking, no single framework exists that thoroughly yet concisely outlines what systems thinking is along with its deep history, theoretical tenets, and soft and hard approaches. This thesis is an attempt to create such a framework, aimed specifically at practical application in a land management agency, through literature synthesis injected with original analysis. The usefulness of the framework is then tested …

Common Learning Every Day: The American Heritage Of Popular (Public And Private P-12) Schooling, Greg Fritzberg, Dick Scheuerman

Day of Common Learning

When it comes to P-12 education, we all have a story, or many stories. We spend almost half of our childhood and adolescent days in schools, most but not all of us in public schools. Not only do we have our own stories, but public (and private) schooling in America has its own story, a heritage of sorts, though one with many strands. The American educational heritage is linked to the preparation of democratic citizens, so its historic successes and failures are of paramount importance. We will tell some shared and/or distinct stories about American education writ large, and solicit …

Using Data-Informed Instruction To Drive Education: Keeping Catholic Education A Viable And Educationally Sound Option In Challenging Times, Kristen Niemeyer, Laura B. Casey, Robert Williamson, Cort Casey, Susan E. Elswick, Tom Black, Denise Winsor

Journal of Catholic Education

This study was conducted to obtain an understanding of the perceptions that Catholic schoolteachers possessed regarding data informed instructional (DII) practices, specifically curriculum based measurement (CBM). The researchers investigated changes in teacher’s perceptions from pretest to posttest to determine the impact of the 90-minute professional development on teacher’s perceptions of DII. Results showed that Catholic schoolteachers did perceive that they lacked sufficient knowledge to effectively implement curriculum-based measures prior to the training. Significant growth was noted with regard to their perceptions of their knowledge in some areas. According to the results of the paired samples t-test, a meaningful change in …

Living Solidarity: Helping Students With Learning Differences Develop Dignity For All Humanity, Tom Malewitz, Beatriz Pacheco

Journal of Catholic Education

Through Evangelii Gaudium (2013) and Laudato si’ (2015) Pope Francis has approached contemporary culture head-on with a call for Catholics to engage, and not retreat from, the changes and challenges of the 21^st century. Traditional expectations and norms of society such as education, occupations, communication, and relationship have been shifting to new horizons through the influence of the recent technological boom.

The purpose of this lesson was to target the essential 21^st century skills of analysis and synthesis in adolescent boys identified as struggling readers. These skills were targeted through the use of the multimodalities available via the …

Losing My Religion? The Impact Of Spiritual Cues On Noncognitive Skills, Daniel H. Bowen, Albert Cheng

Journal of Catholic Education

Studies consistently show that Catholic schools produce positive impacts on educational outcomes. Many charter school networks in the United States now provide, what are essentially, secularized versions of the Catholic education model. However, charter schools cannot legally replicate the overt religious curriculum and mission of Catholic schools. Although difficult to disentangle its impacts from confounding variables, research suggests that religiosity is a positive predictor of educational outcomes. This relationship might suggest that religious-based education produces effects on outcomes of public value that could be difficult to replicate in secularized contexts. To examine this question we conducted an experiment where 180 …

Catholic School Faculty Meetings: A Case Study Linking Catholic Identity, School Improvement, And Teacher Engagement, Daryl C. Hagan, Gary Houchens

Journal of Catholic Education

While research on faculty meetings is limited, existing literature suggests that meetings could be an arena where schools can address their most pressing challenges (Brandenburg, 2008; Michel, 2011; Riehl, 1998). Building on Macey and Schneider’s (2008) Model of Employee Engagement and McGrath’s Model of Group Effectiveness (1964), this case study examined the perceptions of teachers in a high-performing Catholic school regarding their own faculty meetings and how those meetings engaged them in the work of promoting Catholic identity and school improvement. Findings revealed signs of Catholic culture were visible within the physical environment of the faculty meeting, which provided opportunities …

Issue Debates: Notecards In Extemporaneous Speaking, Joseph Kennedy, Jonathan Carter

Speaker & Gavel

Editor's Note: We are trying to bring debatable issues in the community to the forefront. Important contemporary issues are discussed at national tournaments, national conventions, and even at the average weekend tournament. But rarely are these issues written about in our journals. To foster those discussions, and in an effort to document some of the history of intercollegiate forensics, we will have an “Issue Debate” in each issue of Speaker & Gavel. For this issue, two well-known and successful coaches (and top-notch extempers in their day) debate the issue of note card use in extemporaneous speaking. We have seen this …

Geolocator Tracking Of Great Reed-Warblers (Acrocephalus Arundinaceus) Identifies Key Regions For Migratory Wetland Specialists In The Middle East And Sub-Saharan East Africa, Joshua J. Horns, Evam Buechley, Mark William Chynoweth, Lale Aktay, Emrah Çoban, Mehmet Sli Kırpık, Jordan M. Herman, Yakup Şaşmaz, Çağan H. Şekercioğlu

Wildland Resources Faculty Publications

Wetland-dependent migratory songbirds represent one of the most vulnerable groups of birds on the planet, with >67% of wetland-obligate species threatened with extinction. One of the major hurdles for conservation efforts is determining the migration routes, stopover sites, and wintering sites of these species. We describe an annual migration cycle revealed by geolocator tracking of Great Reed-Warblers (Acrocephalus arundinaceus) breeding in the Aras River wetlands of eastern Turkey. Because of its relatively large size and breeding ground fidelity, the Great ReedWarbler is an excellent candidate for geolocator studies and can serve as an indicator species for other wetland songbirds, many …

Collective Influence Of Multiple Spreaders Evaluated By Tracing Real Information Flow In Large- Scale Social Networks, Xian Teng, Sen Pei, Flaviano Morone, Hernán A. Makse

Publications and Research

Identifying the most influential spreaders that maximize information flow is a central question in network theory. Recently, a scalable method called “Collective Influence (CI)” has been put forward through collective influence maximization. In contrast to heuristic methods evaluating nodes’ significance separately, CI method inspects the collective influence of multiple spreaders. Despite that CI applies to the influence maximization problem in percolation model, it is still important to examine its efficacy in realistic information spreading. Here, we examine real-world information flow in various social and scientific platforms including American Physical Society, Facebook, Twitter and LiveJournal. Since empirical data cannot be directly …

Long-Term Data Storage In Diamond, Siddharth Dhomkar, Jacob Henshaw, Harishankar Jayakumar, Carlos A. Meriles

Publications and Research

The negatively charged nitrogen vacancy (NV−) center in diamond is the focus of widespread attention for applications ranging from quantum information processing to nanoscale metrology. Althoughmostwork so far has focused on the NV− optical and spin properties, control of the charge state promises complementary opportunities. One intriguing possibility is the long-term storage of information, a notion we hereby introduce using NV-rich, type 1b diamond. As a proof of principle, we use multicolor optical microscopy to read, write, and reset arbitrary data sets with twodimensional (2D) binary bit density comparable to present digital-video-disk (DVD) technology. Leveraging on the singular dynamics of …

Trouble With The Edtpa: Sliding From Teaching To Preparing For The Test, Stephanie Cronenberg, Dori Johnson, Alexis Jones, Stacey Korson, Natasha Murray, Michael Parrish, Marilyn Johnston-Parsons

Journal of Inquiry and Action in Education

This paper was written by a group of instructors responsible for preparing 100 elementary/middle school licensure students for the edTPA portfolio assessment. It is an analysis of our experiences doing so in the pilot year. The edTPA is a performance assessment required for teacher licensure. We considered this assessment to have significant advantages over a multiple choice test and we debated for a year how best to implement it. Our plan was to integrate what they needed to know into our courses rather than to prepare them directly for the test. We approached this with a positive attitude but emerged …

The Tribology And Chemistry Of Phosphorus Containing Lubricant Additives, David W. Johnson

Chemistry Faculty Publications

Phosphate esters, thiophosphate esters and metal thiophosphates have been used as lubricant additives for over 50 years. Recently, phosphorus‐containing ionic liquids have emerged as a new class of lubricant additives. While the use of phosphorus compounds has been extensive, a detailed knowledge of how they work has been a much more recent development. In this chapter, the use of phosphate esters, thiophosphate esters, metal thiophosphates and phosphorus‐containing ionic liquids as antiwear or extreme pressure additives is discussed. The primary emphasis will be on how they form a protective film, which is both durable and reduces friction. The first part of …

Asymmetric Transformations Catalyzed By Chiral Binol Alkaline Earth Metal Phosphate Complexes, Sri Krishna Nimmagadda

USF Tampa Graduate Theses and Dissertations

Small molecule hydrogen bond donors have emerged as versatile catalysts in asymmetric synthesis. Within this class, chiral BINOL phosphoric acid is regarded as one of the pioneer catalysts used in several asymmetric transformations. The ability of the catalyst to activate the substrates could be controlled in two different ways. (1) Dual activation/bifunctional activation of substrate by hydrogen bond interactions or ion pairing with phosphoric acid or (2) By forming chiral BINOL phosphate metal complex that could significantly alter the interactions in chiral space. In particular, chiral alkaline earth metal phosphate complexes have unique advantages as catalysts owing to the ubiquitous …

Examining Content Validity Of The Nurse Competence Scale In The United States, Jessica B. Shearer

USF Tampa Graduate Theses and Dissertations

Nursing competence is a necessity as it affects public health, safety and welfare; however there are very few reliable and valid tools that measure nursing competence. The Nurse Competence Scale has been used in many different countries outside of the United States and is based on Benner’s Novice to Expert theory. The purpose of this study was to examine the content validity of the Nurse Competence Scale using a mixed methods approach. Descriptive statistics were used to report results of the frequency of use scale and the critical to practice scale. Nursing faculty indicate Prioritizing My Activities Flexibility According to …
