Guidelines For The Development Of Computer-Based Instruction Modules For Science And Engineering, Jessica R. Lux, Barry D. Davidson Jan 2003

Guidelines For The Development Of Computer-Based Instruction Modules For Science And Engineering, Jessica R. Lux, Barry D. Davidson

Mechanical and Aerospace Engineering - All Scholarship

The design and development of a prototype computer-based instruction (CBI) module is described. The module covers introductory structural analysis techniques and demonstrates the practicality of CBI for undergraduate engineering education. The module’s generic learning objectives are used to develop a set of guiding principles for CBI development. Choice of authoring software and the module architecture are presented, followed by the details of the user interface, logic, and screen layout. The module design and software development process outlined here are easily extended to computer-based tutorials that present problem solving methods for engineering, mathematics, and the natural sciences.

Building Problem Solving Environments With Application Web Service Toolkits, Choonhan Youn, Marlon Pierce, Geoffrey C. Fox Jan 2003

Building Problem Solving Environments With Application Web Service Toolkits, Choonhan Youn, Marlon Pierce, Geoffrey C. Fox

Electrical Engineering and Computer Science - All Scholarship

Application portals, or Problem Solving Environments (PSEs), provide user environments that simplify access and integrate various distributed computational services for scientists working on particular classes of problems. Specific application portals are typically built on common sets of core services, so reusability of these services is a key problem in PSE development. In this paper we address the reusability problem by presenting a set of core services built using the Web services model and application metadata services that can be used to build science application front ends out of these core services.

An Xps Investigation Of Thermal Degradation And Charring On Poly(Vinyl Chloride)–Clay Nanocomposites, Jianxin Du, Dongyan Wang, Charles A. Wilkie, Jiangqi Wang Jan 2003

An Xps Investigation Of Thermal Degradation And Charring On Poly(Vinyl Chloride)–Clay Nanocomposites, Jianxin Du, Dongyan Wang, Charles A. Wilkie, Jiangqi Wang

Chemistry Faculty Research and Publications

More information concerning the thermal degradation and charring of nanocomposites of poly(vinyl chloride), dioctyl phthalate and clay has been obtained by the use of X-ray photoelectron spectroscopy and the acquisition of the carbon (C1s), chlorine (Cl2p), and oxygen (O1s) spectra. In the cases of polystyrene–clay and poly(methyl methacrylate)–clay nanocomposites, it has been shown that the clay migrates to the surface as the temperature is raised and the polymer degrades, thereby confirming the barrier properties as a mechanism by which these materials function. For PVC–clay nanocomposites the surface at high temperatures is dominated by carbon, and not the oxygen of the …


Modeling Nonintersective Adjectives Using Operator Logics, Paul Bankston Jan 2003

Modeling Nonintersective Adjectives Using Operator Logics, Paul Bankston

Mathematics, Statistics and Computer Science Faculty Research and Publications

Our topic is one that involves the interface between natural language and mathematical logic. First-order predicate language/logic does a good job approximating many parts of (English) speech, i.e., nouns, verbs and prepositions, but fails decidedly when it comes to, say, adjectives. In particular, it cannot account for the quite different ways in which the adjectives green and big modify a noun such as chair. In the former case, we can easily view a world in which the class of green chairs is the intersection of the class of green things with the class of chair-things. By contrast, the way …


Bayh-Dole Reform And The Progress Of Biomedicine, Arti K. Rai, Rebecca S. Eisenberg Jan 2003

Bayh-Dole Reform And The Progress Of Biomedicine, Arti K. Rai, Rebecca S. Eisenberg

Articles

Advances in fundamental biomedical research play an important and growing role in the development of new therapeutic and diagnostic products. Although the development of pharmaceutical end products has long been a proprietary enterprise, biomedical research comes from a very different tradition of open science. Within this tradition, long-standing norms call for relatively unfettered access to fundamental knowledge developed by prior researchers. The tradition of open science has eroded considerably over the past quarter century as proprietary claims have reached farther upstream from end products to cover fundamental discoveries that provide the knowledge base for future product development.


Redistributing Optimally: Of Tax Rules, Legal Rules, And Insurance, Kyle D. Logue, Ronen Avraham Jan 2003

Redistributing Optimally: Of Tax Rules, Legal Rules, And Insurance, Kyle D. Logue, Ronen Avraham

Articles

From the beginning of the law and economics movement, normative legal economists have focused almost exclusively on evaluating the efficiency of alternative legal rules. The distributional consequences of legal rules, therefore, have largely been ignored. It is tempting to conclude that legal economists are hostile or indifferent to concerns of distributional fairness. In fact, however, the discipline of economics has a great deal to say about distributional policy. The normative branch of economics, known as welfare economics, has always been deeply concerned with distributional issues. It is not that welfare economists purport to know a priori the "right" or "optimal" …


The Fallacy That Fair Use And Information Should Be Provided For Free: An Analysis Of The Responses To The Dmca's Section 1201, Mauricio España Jan 2003

The Fallacy That Fair Use And Information Should Be Provided For Free: An Analysis Of The Responses To The Dmca's Section 1201, Mauricio España

Fordham Urban Law Journal

This Note argues that 17 U.S.C. § 120, Digital Millennium Copyright Act, is not only necessary to ensure that copyright law is able to progress and advance in the digital revolution, but more importantly, that the protection of copyrighted works will benefit the public in ways the analog world cannot. It also argues that legal commentators' fears about § 1201 are misplaced.

Where Is Sherlock Holmes?, Jeffrey C. Goodman Jan 2003

Where Is Sherlock Holmes?, Jeffrey C. Goodman

Faculty Scholarship

Most philosophers would say that fictional characters lack spatiotemporal location simply because such entities do not exist.  However, even prominent believers in ficta hold that they must lack location.  I here focus on the views of one such believer, Amie Thomasson, and her Artifactual Theory.  The fundamentals of her ontology seem correct, but I argue that the view implies that ficta do have location.  I provide a diagnosis of an argument Thomasson gives for the contrary, and then suggest a way for the Artifactual Theory to account for the locations of ficta.  I conclude by discussing some potential applications of …

Formal Concept Analysis And Resolution On Algebraic Domains - Preliminary Report, Matthias Wendt, Pascal Hitzler Jan 2003

Formal Concept Analysis And Resolution On Algebraic Domains - Preliminary Report, Matthias Wendt, Pascal Hitzler

Computer Science and Engineering Faculty Publications

We relate two formerly independent areas: Formal concept analysis and logic of domains. We will establish a correspondence between contextual attribute logic on formal contexts resp. concept lattices and a clausal logic on coherent algebraic cpos. We show how to identify the notion of formal concept in the domain theoretic setting. In particular, we show that a special instance of the resolution rule from the domain logic coincides with the concept closure operator from formal concept analysis. The results shed light on the use of contexts and domains for knowledge representation and reasoning purposes.


Learning Continuous Latent Variable Models With Bregman Divergences, Shaojun Wang, Dale Schuurmans Jan 2003

Learning Continuous Latent Variable Models With Bregman Divergences, Shaojun Wang, Dale Schuurmans

Kno.e.sis Publications

We present a class of unsupervised statistical learning algorithms that are formulated in terms of minimizing Bregman divergences— a family of generalized entropy measures defined by convex functions. We obtain novel training algorithms that extract hidden latent structure by minimizing a Bregman divergence on training data, subject to a set of non-linear constraints which consider hidden variables. An alternating minimization procedure with nested iterative scaling is proposed to find feasible solutions for the resulting constrained optimization problem. The convergence of this algorithm along with its information geometric properties are characterized.


Standards For Science Teacher Preparation, National Science Teachers Association Jan 2003

Standards For Science Teacher Preparation, National Science Teachers Association

Department of Teaching, Learning, and Teacher Education: Faculty Publications

Any project intending to write education standards for national dissemination and implementation is immediately confronted with the fact that education is a state function, and that the fifty states, plus Puerto Rico, each have their own ideas about what should be taught to their children. Education, unlike many professions, is a highly political act: parents and guardians are concerned about what their children are taught; and various stakeholders have their own ideas about what constitutes a good education. Whether or not they are directly engaged in setting standards, they want to know why a particular set of standards has been …


Temperature Variations From Hubble Space Telescope Spectroscopy Of The Orion Nebula, R. H. Rubin, P. G. Martin, R. J. Dufour, Gary J. Ferland, K. P. M. Blagrave, X.-W. Liu, J. F. Nguyen, J. A. Baldwin Jan 2003

Temperature Variations From Hubble Space Telescope Spectroscopy Of The Orion Nebula, R. H. Rubin, P. G. Martin, R. J. Dufour, Gary J. Ferland, K. P. M. Blagrave, X.-W. Liu, J. F. Nguyen, J. A. Baldwin

Physics and Astronomy Faculty Publications

We present Hubble Space Telescope (HST)/STIS long-slit spectroscopy of NGC 1976. Our goal is to measure the intrinsic line ratio [O III] 4364/5008 and thereby evaluate the electron temperature (Te) and the fractional mean-square Te variation (t2A)across the nebula. We also measure the intrinsic line ratio [N II] 5756/6585 in order to estimate Te and t2A in the N+region. The interpretation of the [N II] data is not as clear cut as the [O III] data because of a higher sensitivity to knowledge …
