Development And Design Of A Merged Secondary And Special Education Teacher Preparation Program, Ann Fullerton, Barbara Ruben, Stephanie Mcbride, Susan Bert

Curriculum and Instruction Faculty Publications and Presentations

As middle and secondary classrooms become increasingly inclusive, some special educators may not be prepared to teach content, and some general educators may not be prepared to address diverse learning needs. This mismatch between the reality of today's schools and traditional teacher preparation has led to the development of new models for teacher education that integrate or merge special education and general education. Integrated and merged models are two approaches to combining special and general education pedagogy for teacher education. In merged programs, faculty in general and special education collaborate to develop one program in which all candidates receive licensure …

Organometallic Iron(Iii)-Salophene Exerts Cytotoxic Properties In Neuroblastoma Cells Via Mapk Activation And Ros Generation, Kyu Kwang Kim, Rakesh K. Singh, Robert M. Strongin, Richard G. Moore, Laurent Brard, Thilo S. Lange

Chemistry Faculty Publications and Presentations

The objective of the present study was to investigate the specific effects of Iron(III)-salophene (Fe-SP) on viability, morphology, proliferation, cell cycle progression, ROS generation and pro-apoptotic MAPK activation in neuroblastoma (NB) cells. A NCI-DTP cancer screen revealed that Fe-SP displayed high toxicity against cell lines of different tumor origin but not tumor type-specificity. In a viability screen Fe-SP exhibited high cytotoxicity against all three NB cell lines tested. The compound caused cell cycle arrest in G1 phase, suppression of cells progressing through S phase, morphological changes, disruption of the mitochondrial membrane depolarization potential, induction of apoptotic markers as well as …

Investigation And Evaluation Of Current And Emerging Whole-Water Sampling Technologies For U.S. Geological Survey National Water Quality Assessment Program, Keith D. Gareau

Environmental Science and Management Professional Master's Project Reports

An investigation was conducted into current and emerging surface water sampling technologies. These technologies were compared and recommendations given to the United States Geological Survey (USGS) for adoption by the National Water Quality Assessment (NAWQA) Program. The goal is to reduce labor costs and increase information content. This paper examines lotic system samplers, portable autonomous whole-water samplers, and autonomous submergible whole-water samplers. When investigating whole-water sampling technology, it was imperative to take into consideration what chemical classifications can be sampled for by each respected technology. Chemical classifications considered are: emerging contaminants, major ions, nutrients, polychlorinated biphenyls, pesticides, volatile and semi-volatile …

Macroinvertebrate Community Analysis On Lower Hood River Before And During The Removal Of Powerdale Dam: A Baseline Study, Howard Jay Patterson

Environmental Science and Management Professional Master's Project Reports

Powerdale Dam was an 87-year-old hydroelectric complex on lower Hood River in northern Oregon which was decommissioned in 2010. Macroinvertebrate samples were collected in 2009, before the removal process began, and in 2010, near the end of the demolition project, at one site upstream and three sites downstream of the dam. Macroinvertebrate communities were analyzed using both multi-metric (Benthic Index of Biotic Integrity [B-IBI]) and multivariate (Predictive Assessment Tool for Oregon [PREDATOR]) approaches, as well as EPT and Functional Feeding Group (FFG) analysis. All analytical approaches indicated declines in habitat quality in 2010 relative to 2009, and showed increasing impairment …

Evaluation Of A Merged Secondary And Special Education Program, Ann Fullerton Dr., Barbara Ruben, Stephanie Mcbride, Susan Bert

Curriculum and Instruction Faculty Publications and Presentations

If classroom teachers are among the greatest determinant of student learning, then teacher preparation programs have a role to play improving educational outcomes for struggling learners. There are currently three established teacher preparation program models: (1) "discrete"; (2) "integrated"; and (3) "merged." In the "discrete" model, which is the most widely implemented of the three, general and special education programs are separate. In the "integrated" model, separate programs are retained but faculty work together to develop some courses and/or field experiences in which special education candidates learn about the general education curriculum while general education candidates learn about inclusive education. …

Understanding the complexity of human–nature interactions is central to the quest for both human well-being and global sustainability. To build an understanding of these interactions, scientists, planners, resource managers, policy makers, and communities increasingly are collaborating across wide-ranging disciplines and knowledge domains. Scientists and others are generating new integrated knowledge on top of their requisite specialized knowledge to understand complex systems in order to solve pressing environmental and social problems (e.g., Carpenter et al. 2009). One approach to this sort of integration, bringing together detailed knowledge of various disciplines (e.g., social, economic, biological, and geophysical), has become known as the …

Modal Logic And Its Applications, Explained Using Puzzles And Examples, Marek Perkowski

Systems Science Friday Noon Seminar Series

The talk introduces Modal Logic as an extension of classical propositional and First Order Logics. We discuss motivations of Lewis to create modal logic system, axioms and rules of proof. Several examples illustrate deriving theorems from axioms. "Muddy Children" puzzle is used to explain the principles of dealing with uncertainty problems where a temporal lack of response is used as additional information. Other examples include "Narrow Bridge" problem/game which relates to the problem of necessary evil in the world, robot planning and law and robot morality problems, especially related to military robots and use of force by police. Kripke semantics …

Impact Of The Cyprus Problem On Cfsp And Regional Power Transition In Europe, Birol A. Yeşilada

Political Science Faculty Publications and Presentations

Mathematicians posited that a “butterfly effect”might be present in complex interactions. Relationships between Power Transition in Europe, the future of European Union’s (EU) Common Foreign and Security Policy (CFSP), and protracted Cyprus conflict are examples of this phenomenon. On the one hand, findings from Power Transition analysis indicate significant shift in global and regional hierarchies where the EU is expected to fall behind its global competitions –namely China, the United States, and India (Tammen et al, 2000; Yesilada, Efird, and Noordijk 2006). On the other hand, closer this “rising threat of China” can be postponed by a deeper degree of …

Generalized Construction Of Scalable Concurrent Data Structures Via Relativistic Programming, Josh Triplett, Paul E. Mckenney, Philip W. Howard, Jonathan Walpole

Computer Science Faculty Publications and Presentations

We present relativistic programming, a concurrent programming model based on shared addressing, which supports efficient, scalable operation on either uniform shared-memory or distributed shared- memory systems. Relativistic programming provides a strong causal ordering property, allowing a series of read operations to appear as an atomic transaction that occurs entirely between two ordered write operations. This preserves the simple immutable-memory programming model available via mutual exclusion or transactional memory. Furthermore, relativistic programming provides joint-access parallelism, allowing readers to run concurrently with a writer on the same data. We demonstrate a generalized construction technique for concurrent data structures based on relativistic programming, …

Scalable Correct Memory Ordering Via Relativistic Programming, Josh Triplett, Philip William Howard, Paul E. Mckenney, Jonathan Walpole

Computer Science Faculty Publications and Presentations

We propose and document a new concurrent programming model, relativistic programming. This model allows readers to run concurrently with writers, without blocking or using expensive synchronization. Relativistic programming builds on existing synchronization primitives that allow writers to wait for current readers to finish with minimal reader overhead. Our methodology models data structures as graphs, and reader algorithms as traversals of these graphs; from this foundation we show how writers can implement arbitrarily strong ordering guarantees for the visibility of their writes, up to and including total ordering.

Some Problems And Solutions In The Experimental Science Of Technology: The Proper Use And Reporting Of Statistics In Computational Intelligence, With An Experimental Design From Computational Ethnomusicology, Mehmet Vurkaç

Systems Science Friday Noon Seminar Series

Statistics is the meta-science that lends validity and credibility to The Scientific Method. However, as a complex and advanced Science in itself, Statistics is often misunderstood and misused by scientists, engineers, medical and legal professionals and others. In the area of Computational Intelligence (CI), there have been numerous misuses of statistical techniques leading to the publishing of insupportable results, which, in addition to being a problem in itself, has also contributed to a degree of rift between the Statistics/Statistical Learning community and the Machine Learning/Computational Intelligence community. This talk surveys a number of misuses of statistical inference in CI settings, …

Development Of An Open Source Bridge Management System, Michael H. Scott

TREC Final Reports

A bridge management system is developed using the Tcl scripting language in conjunction with the OpenSees finite element software framework. Fully programmable and string-based, Tcl is ideal for implementing live load analysis through scripts and experimenting with emergent bridge rating methodologies. Since Tcl is an interpreted language, the application also has the important advantage that new bridge capacity models and rating factor calculations can be implemented on multiple platforms without compiling source code. The network programming features of Tcl give the system access to databases for conducting internet-based bridge rating. The system is demonstrated for rating a conventionally reinforced concrete …

A Comparison Of Relativistic And Reader-Writer Locking Approaches To Shared Data Access, Philip William Howard, Josh Triplett, Jonathan Walpole

Computer Science Faculty Publications and Presentations

This paper explores the relationship between reader-writer locking and relativistic programming approaches to managing accesses to shared data. It demonstrates that by placing certain restrictions on writers, relativistic programming allows more concurrency than reader-writer locking while still providing the same isolation guarantees. Relativistic programming also allows for a straightforward model for reasoning about the correctness of programs that allow concurrent read-write accesses.

On The Effect Of Criticality And Topology On Learning In Random Boolean Networks, Alireza Goudarzi

Systems Science Friday Noon Seminar Series

Random Boolean networks (RBN) are discrete dynamical systems composed of N automata with a binary state, each of which interacts with other automata in the network. RBNs were originally introduced as simplified models of gene regulation. In this presentation, I will present recent work done conjointly with Natali Gulbahce (UCSF), Thimo Rohlf (MPI, CNRS), and Christof Teuscher (PSU). We extend the study of learning in feedforward Boolean networks to random Boolean networks (RBNs) and systematically explore the relationship between the learning capability, the network topology, the system size N, the training sample T, and the complexity of the computational task. …

Information Disclosure And Environmental Performance, Mark Stephan

Systems Science Friday Noon Seminar Series

Scholars and policymakers increasingly argue that information disclosure programs such as the Toxics Release Inventory (TRI) should be used to supplement conventional environmental regulation. Yet we lack a clear understanding of how such programs work as well as the empirical data to confirm their success in achieving environmental quality objectives. To better understand the impacts of environmental information disclosure on corporate decision making, this paper develops an analytic framework drawn from theories of risk perception and communication, individual and corporate decision making, and social capital. I examine the importance of the TRI for facility level behavior through an analysis of …
