Development Of A Calix[4]Arene Sensor For Soft Metals Based On Nitrile Functionality, Benjamin Schazmann, Dermot Diamond

Articles

The current work is amongst the first to examine the potential usefulness of the nitrile functional group in potentiometric analytical sensors for soft metals. Nitrile functionality has hereby been incorporated into a calix[4]arene skeleton to give a series of new cation selective hosts. The analytical sensing behaviour of these hosts was examined by Ion Selective Electrode (ISE) based potentiometry. In all cases a preference for soft metals was observed, explained primarily in terms of soft–soft compatibility between calix[4]arene nitrile hosts and metal guests in combination with a classical ‘lock and key’ best fit mechanism. Hosts 2, 3 and 4 showed …

An Experience On Problem Based Learning In An Engineering Faculty, Cüneyt Güzeli̇ş

Turkish Journal of Electrical Engineering and Computer Sciences

In 2001, Engineering Faculty of Dokuz Eylül University has started to change its undergraduate education in a radical way. As being among the first examples in the world, the Departments of Electrical and Electronics, Geological and Geophysics Engineering in 2002 and Mining Engineering Department in 2003 have adopted the so-called "modular-staged problem based active learning system". The system is based on real engineering problems which values teamwork and the integration of information from different disciplines and it places the student at the center of the learning process. The faculty has learned many things and it needs to learn many other …

An Explicit Scheme For Multifluid Magnetohydrodynamics, Stephen O'Sullivan, Turlough Downes

Articles

When modelling astrophysical fluid flows, it is often appropriate to discard the canonical magnetohydrodynamic approximation, thereby freeing the magnetic field to diffuse with respect to the bulk velocity field. As a consequence, however, the induction equation can become problematic to solve via standard explicit techniques. In particular, the Hall diffusion term admits fast-moving whistler waves which can impose a vanishing time-step limit.Within an explicit differencing framework, a multifluid scheme for weakly ionized plasmas is presented which relies upon a new approach to integrating the induction equation efficiently. The first component of this approach is a relatively unknown method of accelerating …

Inverse Scattering Transform For The Camassa-Holm Equation, Adrian Constantin, Vladimir Gerdjikov, Rossen Ivanov

Articles

An Inverse Scattering Method is developed for the Camassa-Holm equation. As an illustration of our approach the solutions corresponding to the reflectionless potentials are constructed in terms of the scattering data. The main difference with respect to the standard Inverse Scattering Transform lies in the fact that we have a weighted spectral problem. We therefore have to develop different asymptotic expansions.

The intent of the program was to increase the ninth grade student's academic and social success by having parents involved in the transition along with various transition activities. To accomplish this purpose, a review of current literature, research and selected programs related to transitioning middle school students and parent involvement in the transition, were examined. The culminating guide was designed and …

Instructional Writing Strategies For The Secondary Teacher: A Handbook To Guide Content Area Teachers Implementing Writing Into Curriculum, Cathy S. Thompson

All Graduate Projects

Secondary teachers are concerned that their students are having difficulties learning and retaining difficult concepts present in secondary curricula. Additionally, students may not be learning the content at a deep enough knowledge level to pass stringent high-stakes standardized tests required for graduation in the state of Washington. For students to succeed in the competitive global economy they must become self-monitoring critical thinkers. Research supports the use of writing-to-learn and content area writing strategies to facilitate metacognition and boost student learning. This project reviews the research in writing and metacognition, synthesizes the findings, and applies the results in a series of …

Trans-Atlantic Correlation Of Upper Cretaceous Marine Sediments, Marcus R. Ross, David E. Fastovsky

Faculty Publications and Presentations

Upper Cretaceous marine deposits from the Mid-Atlantic region of North America (Delaware, Maryland, and New Jersey) and the Maastricht area (southern Netherlands, and nearby Belgium and Gennany) are correlated across the Atlantic using a variety of macro invertebrates, nannofossils, and sequence stratigraphy. Four late Cretaceous Mid-Atlantic sequences, the Marshalltown, Englishtown, Merchantville, and Navesink, span the upper Santonian to lowennost Danian, and have direct correlatives in the Maastricht area. Correlations between the Mid-Atlantic and the Maastricht regions (respectively) are as follows: the upper Santonian to lower Campanian Merchantville and Matawan formations with the Achen and lower Vaals fonnations; the middle Campanian …

Product Customization On The Web: An Empirical Study Of Factors Impacting Choiceboard User Satisfaction, Pratyush Bharati, Abhijit Chaudhury

Management Science and Information Systems Faculty Publication Series

Choiceboards are Web-based systems that allow consumers to customize their orders. The study investigated factors that affect consumers’ intention to use choiceboards. The research is based on Masons’ theory and DeLone and McLean’s model of information system use. It was found that intention to use is affected by overall satisfaction. In turn, these two factors are positively impacted by factors such as system quality and information quality. In spite of support from theory, the evidence for the factor, information presentation was weak.

A Price Theory Of Legal Bargaining: An Inquiry Into The Selection Of Settlement And Litigation Under Uncertainty, Robert J. Rhee

UF Law Faculty Publications

Conventional wisdom says that economic surplus is created when the cost of litigation is foregone in favor of settlement, a theory flowing from the Coase Theorem. The cost-benefit analysis weighs settlement against the expected value of litigation net of transaction cost. This calculus yields the normative proposition that settlement is a superior form of dispute resolution and so most trials are considered errors. While simple in concept, the prevailing economic model is flawed. This article is a theoretical inquiry into the selection criteria of settlement and trial. It applies principles of financial economics to construct a pricing theory of legal …

Delaware Bankruptcy: Failure In The Ascendancy, Lynn M. Lopucki, Joseph W. Doherty

UF Law Faculty Publications

In 1990, the United States Bankruptcy Court for the District of Delaware - then a one-judge backwater - began competing for big bankruptcy cases. In six years, that court achieved a near monopoly. In 2000, LoPucki and Kalin discovered that 42% of the companies filing in Delaware during that six year period of ascendency refiled bankruptcy within five years of their emergence, as compared with only 6% of those filing in courts other than Delaware and New York. In a later study, we found the (1) the failure of the companies reorganized in Delaware during the period of ascendency was …

Microarray Based Comparison Of Two Escherichia Coli O157:H7 Lineages, Scot E. Dowd, Hiroshi Ishizaki

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Background: Previous research has identified the potential for the existence of two separate lineages of Escherichia coli O157:H7. Clinical isolates tended to cluster primarily within one of these two lineages. To determine if there are virulence related genes differentially expressed between the two lineages we chose to utilize microarray technology to perform an initial screening.

Results: Using a 610 gene microarray, designed against the E. coli O157 EDL 933 transcriptome, targeting primarily virulence systems, we chose 3 representative Lineage I isolates (LI groups mostly clinical isolates) and 3 representative Lineage II isolates (LII groups mostly bovine isolates). Using standard dye …

Controlling Charge Injection In Organic Field-Effect Transistors Using Self-Assembled Monolayers, B H. Hamadani, D A. Corley, Jacob W. Ciszek, J M. Tour, D Natelson

Chemistry: Faculty Publications and Other Works

We have studied charge injection across the metal/organic semiconductor interface in bottom-contact poly(3-hexylthiophene) (P3HT) field-effect transistors, with Au source and drain electrodes modified by self-assembled monolayers (SAMs) prior to active polymer deposition. By using the SAM to engineer the effective Au work function, we markedly affect the charge injection process. We systematically examine the contact resistivity and intrinsic channel mobility and show that chemically increasing the injecting electrode work function significantly improves hole injection relative to untreated Au electrodes.

The Effects Of Varying The Timing Of Inputs On A Neural Oscillator, Christina Ambrosio-Mouser, Farzan Nadim, Amitabha Bose

Publications and Research

The gastric mill network of the stomatogastric ganglion of the crab Cancer borealis is comprised of a set of neurons that require modulatory input from outside the stomatogastric ganglion and input from the pyloric network of the animal in order to oscillate. Here we study how the frequency of the gastric mill network is determined when it receives rhythmic input from two different sources but where the timing of these inputs may differ. We find that over a certain range of the time difference one of the two rhythmic inputs plays no role what so ever in determining the network …

Editorial 1: Unpacking The Complexity Of The Homonym Site/Sight/Cite, Jan Jagodzinski

Journal of Social Theory in Art Education

We invite essays that explore visual regimes that have become established in our public schools or art departments. "Out of sight" might interrogate current ideals, territories, and debates concerning visual cultural education, since this was a distant horizon first discussed in JSTAE in 1980 and is now looming closer in mainstream art education. "Out of sight" might provide us with concerns over our televised, cinematic images that come at us through popular culture. For Lacan, sight was always a form of misrecognition, a form of "ignorance" as brilliantly explored by Magritte. We are all framed by images. So, we invite …

Marginalia And Meaning: Off-Site/Sight/Cite Points Of Reference For Extended Trajectories In Learning, James Haywood Rolling Jr.

Journal of Social Theory in Art Education

This study argues that drawing upon off-site/ sight/ cite points of reference affords a space for extended trajectories of learning and the cultivation of rich and atypical personal meaning unavailable within the terrain and climes of typical schooling frameworks. This paper continues the author's effort to establish the efficacy of a poststructural and poetic aesthetic in qualitative research writing.

Two-Year College Faculty And Administrator Perceptions Of The Transition To A Learning-Centered College, John Michael Brackin

Theses and Dissertations

A single qualitative case study design was used to determine the perceptions of administrators and faculty from a community college that is considered to be transitioning to a learning-centered college. The researcher conducted the case study to describe, explain and evaluate the phenomenon, and also recorded facilitators or roadblocks identified during the process. A conceptual framework model was used to produce an auditing procedure that identified the progress, perceptions and status of the community college as it transitioned to become a learning-centered college. Interviews of administrators and faculty, a survey of full-time faculty, and document reviews were the primary means …

Social Productivity, Law, And The Regulation Of Conflicts Of Interest In The Investment Industry, Larry D. Barnett

Cardozo Public Law, Policy & Ethics Journal

The article introduces the concept of "social productivity," a sociological framework analyzing how organized groups influence society through their actions and policies. It distinguishes social productivity from economic productivity by focusing on social outputs like reputation, symbols, trust, and behavioral standards, which can enhance or diminish societal well-being. The article argues that law plays a critical role in mitigating harm and restoring trust by regulating behavior and reflecting societal values. It advocates for considering social productivity in policy and legal frameworks to foster a stable society, emphasizing the non-economic impacts of group actions on the social fabric.

Cognitive Engineering Research Methodology: A Proposed Study Of Visualization Analysis Techniques, Cristin M. Hall, Sonya A.H. Mcmullen, David L. Hall

Publications

The rapid development of new sensors and wide-band communications provides the capability to collect enormous amounts of data. An increasing challenge involves how to understand and interpret the data to yield knowledge about evolving situations or threats (e.g., of military situations, state of complex systems, etc.). New visualization tools and techniques are becoming available to support advanced visualization including three-dimensional, full immersion display environments and tools to support novel visualizations. Examples include network system display tools and evolving multi-sensory situation environments. Despite the emergence of such tools, there has been limited systematic test and evaluations to determine the efficacy of …

A New Approach To Identify Functional Modules Using Random Matrix Theory, Mengxia Zhu, Qishi Wu, Yunfeng Yang, Jizhong Zhou

Computer Science Publications

The advance in high-throughput genomic technologies including microarrays has generated a tremendous amount of gene expression data for the entire genome. Deciphering transcriptional networks that convey information on members of gene clusters and cluster interactions is a crucial analysis task in the post-sequence era. Most of the existing analysis methods for large-scale genome-wide gene expression profiles involve several steps that often require human intervention. We propose a random matrix theory-based approach to analyze the cross correlations of gene expression data in an entirely automatic and objective manner to eliminate the ambiguities and subjectivity inherent to human decisions. The correlations calculated …

The Stable Manifold Theorem For Semilinear Stochastic Evolution Equations And Stochastic Partial Differential Equations, Salah-Eldin A. Mohammed, Tusheng Zhang, Huaizhong Zhao

Articles and Preprints

The main objective of this paper is to characterize the pathwise local structure of solutions of semilinear stochastic evolution equations (see’s) and stochastic partial differential equations (spde’s) near stationary solutions. Such characterization is realized through the long-term behavior of the solution field near stationary points. The analysis falls in two parts 1, 2.

In Part 1, we prove general existence and compactness theorems for C^k-cocycles of semilinear see’s and spde’s. Our results cover a large class of semilinear see’s as well as certain semilinear spde’s with Lipschitz and non-Lipschitz terms such as stochastic reaction diffusion equations and the …

Totally Magic Injections Of Graphs, John P. Mcsorley

Articles and Preprints

For a simple graph G consider an injection μ : V U E -> N. If for every vertex x in V we have μ(x) + Sum μ(xy) = h where y is adjacent to x, and for every edge xy in E we have μ(x) + μ(xy) + μ(y) = k, for some constants h and k, then μ is a totally magic injection (TMI) of G. Also, mt(G) is the smallest natural number such that there is a TMI μ : V U E --> {1, 2, . . . ,mt(G)}. Here we study TMIs and the number …
