Information Disclosure And Environmental Performance, Mark Stephan Jan 2011

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 …

Compared To What? Reconsidering Assessment In Higher Education, Gary R. Brown Jan 2011

Compared To What? Reconsidering Assessment In Higher Education, Gary R. Brown

Office of Academic Innovation Publications

There is, as Peter Ewell has recently observed, a tension between accountability and improvement. Batson elaborates, noting the parallel realization is dawning that tracking student outcomes toward learning goals, while a useful and necessary exercise, does not yield as much value as we had thought. Batson argues that developing an accountability system has provided rewards to faculty and student painfully insufficient to warrant the work such development requires. Batson argues that ePortfolios provide a rich alternative. This presentation will demonstrate with real student ePortfolio case studies nested within the context of organizational ePortfolio to provide an example that suggests Batson's …

Why The Block Is The Block: Reinforcing Community Through Casual Conversation, L. David Ritchie Jan 2011

Why The Block Is The Block: Reinforcing Community Through Casual Conversation, L. David Ritchie

Communication Faculty Publications and Presentations

This study combines Discourse Dynamics (Cameron, 2007) with Perceptual Simulation Theory (Barsalou, 2007; Gibbs, 2006), to analyze a sample of talk among residents of an urban neighborhood about topics related to community safety and the quality of life in their community. The results demonstrate the role of casual conversation in structuring complex social relationships, and the usefulness of close attention to metaphors, story-telling, and humor. By their use, re-use, and development of metaphors and stories the participants in this conversation express and reinforce the patterns of sociability and mutual watchfulness that contribute to a feeling of safety and comfort in …

The Negotiation Of Writer Identity In Engineering Faculty - Writing Consultant Collaborations, Sarah Read Jan 2011

The Negotiation Of Writer Identity In Engineering Faculty - Writing Consultant Collaborations, Sarah Read

English Faculty Publications and Presentations

Negotiating faculty-writing consultant collaborations in engineering contexts can be challenging when the writing consultant originates in the humanities. The author found that one of the sites of negotiation in the formation of working relationships is that of writer identity, and disciplinary writer identity in particular. In order to confirm her experiential knowledge, the author interviewed her faculty collaborators to further investigate their attitudes and experiences about writing. Analysis of two excerpts of these interviews makes visible "clashes" between the faculty engineers' and the writing consultant's autobiographical and disciplinary writer identities. Implications of the role of writer identity in faculty-writing consultant …

Youth Movement: Building Assets Of Community For School Reform, Ethan Johnson, Andraé Brown Jan 2011

Youth Movement: Building Assets Of Community For School Reform, Ethan Johnson, Andraé Brown

Black Studies Faculty Publications and Presentations

Social capital can be used to measure the health and wellness of a community. Through an ethnographic account of one school and community in Northern California, we demonstrate how social and economic forces diminished this community’s social capital and consequently its health. We also show how one community-based organization took into account this larger social and economic context to develop creative interventions to address interracial violence within a school. Their efforts built trust, increased social networks and accountability, which resulted in empowering previously marginalized members of the community. Organizers encouraged counselors to work creatively to expand their scope of their …

'Sticky Spots' And Subglacial Lakes Under Ice Streams Of The Siple Coast, Antarctica, Olga V. Sergienko, Christina L. Hulbe Jan 2011

'Sticky Spots' And Subglacial Lakes Under Ice Streams Of The Siple Coast, Antarctica, Olga V. Sergienko, Christina L. Hulbe

Geology Faculty Publications and Presentations

Locations of subglacial lakes discovered under fast-moving West Antarctic ice streams tend to be associated with topographic features of the subglacial bed or with areas that have strong variations in basal conditions. Inversion of ice-stream surface velocity indicates that basal conditions under ice streams can be highly variable and that there can be widespread regions where basal traction is high. To seek an explanation for why lakes appear to be sited near areas with high basal traction, we use numerical models to simulate ice-stream dynamics, thermodynamics and subglacial water flow. We demonstrate that the ice flow over high basal traction …

A Comparative Case Study Of Newspaper Coverage Of The Umatilla Chemical Weapons Depot/Incinerator From 1994 To 1998., Rogue Elliott Robertson Jan 2011

A Comparative Case Study Of Newspaper Coverage Of The Umatilla Chemical Weapons Depot/Incinerator From 1994 To 1998., Rogue Elliott Robertson

Dissertations and Theses

The purpose of this case study was to compare the news coverage of The Umatilla chemical weapons by examining newspapers from different communities: The Oregonian and The Hermiston Herald. The author examines solution frames, pluralistic frames, episodic frames, and thematic frames and compares them across two newspapers. The study found the difference was not significant when comparing the use of solution frames between The Hermiston Herald and The Oregonian. In addition, there was not a significant difference in use of pluralistic framing by The Hermiston Herald and The Oregonian. However, there was a significant difference in the sources presented in …

An Investigation On Fast And Frugal Model For New Project Screening, Antonie J. Jetter, Fatima M. Albar Jan 2011

An Investigation On Fast And Frugal Model For New Project Screening, Antonie J. Jetter, Fatima M. Albar

Engineering and Technology Management Faculty Publications and Presentations

Research in psychology is increasingly interested in decision-makers' use of heuristics or rules of thumb because they have accuracies close to more complex decision rules and seem particularly useful in difficult decision-making contexts when uncertainty is high and speed is of the essence. One particularly difficult decision setting is the fuzzy front-end of new product development because a large number of product ideas need to be screened to identify the few that should be developed further. This process is currently poorly supported through decision tools and mainly occurs on the basis of managerial “gut-feel”. This study explores managerial “gut-feel” by …

Haskell For The Cloud, Andrew P. Black Jan 2011

Haskell For The Cloud, Andrew P. Black

Computer Science Faculty Publications and Presentations

We present Cloud Haskell, a domain specific language for developing programs for a distributed-memory computing environment. Implemented as a shallow embedding in Haskell, it provides a message-passing communication model, inspired by Erlang, without introducing incompatibility with Haskell's established sharedmemory concurrency. A key contribution is a method for serializing function closures for transmission across the network. Cloud Haskell has been implemented; we present example code and some preliminary performance measurements.

Can Transportation Researchers Reuse Project Datasets And Programs?, Tyler Hayes, Lois Delcambre, Leonard Shapiro Jan 2011

Can Transportation Researchers Reuse Project Datasets And Programs?, Tyler Hayes, Lois Delcambre, Leonard Shapiro

Computer Science Faculty Publications and Presentations

Data users involved in research and analysis typically invest a lot of eort cleaning and manipu- lating their data as they work. Based on this observation, we have investigated two hypotheses: 1) reuse of datasets and procedures is difficult, and 2) the inability to reuse datasets and procedures is primarily due to a lack of documentation. To test these hypotheses we conducted structured interviews with data users asking questions regarding the struggles in their work pertaining to data, their documentation habits, and the importance of documentation. The interviews revealed that the data users rarely reused data or procedures, frequently encountered …

Tropical Salvage: From Recession To Expansion, Scott Marshall, Lisa Peifer, Erin Ferrigno Jan 2011

Tropical Salvage: From Recession To Expansion, Scott Marshall, Lisa Peifer, Erin Ferrigno

Business Faculty Publications and Presentations

Tim O’Brien, founder of Tropical Salvage, was preparing for another warehouse clearance sale of his unique, handcrafted hardwood furniture. It had been an enormously challenging year and it was important to reduce inventory before the next container arrived from Indonesia. The market for fine furniture had begun to decline steadily in early 2008 following the stock market crash of the prior September. The company survived a difficult period, but not without suffering a decline in sales. O’Brien had spent ten years building a sustainable business model based on environmental stewardship, worker empowerment and unique, high quality product. As the economy …

Relativistic Red-Black Trees, Philip William Howard, Jonathan Walpole Jan 2011

Relativistic Red-Black Trees, Philip William Howard, Jonathan Walpole

Computer Science Faculty Publications and Presentations

Operating system performance and scalability on sharedmemory many-core systems depends critically on efficient access to shared data structures. Scalability has proven difficult to achieve for many data structures. In this paper we present a novel and highly scalable concurrent red-black tree. Red-black trees are widely used in operating systems, but typically exhibit poor scalability. Our red-black tree has linear read scalability, uncontended read performance that is at least 25% faster than other known approaches, and deterministic lookup times for a given tree size, making it suitable for realtime applications.

The Ordering Requirements Of Relativistic And Reader-Writer Locking Approaches To Shared Data Access, Philip William Howard, Josh Triplett, Jonathan Walpole, Paul E. Mckenney Jan 2011

The Ordering Requirements Of Relativistic And Reader-Writer Locking Approaches To Shared Data Access, Philip William Howard, Josh Triplett, Jonathan Walpole, Paul E. Mckenney

Computer Science Faculty Publications and Presentations

The semantics of reader-writer locks allow read-side concurrency. Unfortunately, the locking primitives serialize access to the lock variable to an extent that little or no concurrency is realized in practice for small critical sections. Relativistic programming is a methodology that also allows read- side concurrency. Relativistic programming uses dfferent ordering constraints than reader-writer locking. The different ordering constraints allow relativistic readers to proceed without synchronization so relativistic readers scale even for very short critical sections. In this paper we explore the diferences between the ordering constraints for reader-writer locking and relativistic programs. We show how and why the dfferent ordering …

Toward A Taxonomy Of Diversity At Work: Developing And Validating The Workplace Diversity Inventory, Aisha Smith Taylor Jan 2011

Toward A Taxonomy Of Diversity At Work: Developing And Validating The Workplace Diversity Inventory, Aisha Smith Taylor

Dissertations and Theses

The purpose of this research was to develop a taxonomy of workplace diversity and examine its implications for understanding and predicting diversity at work. A 7-dimension taxonomy was originally developed by reviewing contemporary literature on diversity in the workplace. The taxonomy is grounded in Social Identity Theory. Preliminary research found that each of the seven dimensions of the taxonomy were present in 78 critical incidents describing work-relevant diversity dynamics. The current study reports the development and administration of an instrument, the Workplace Diversity Inventory (WDI), which was used to empirically examine the 7-factor model of the taxonomy in over 20 …

A Multi-Level Study Of The Predictors Of Family-Supportive Supervision, Ginger Charmagne Hanson Jan 2011

A Multi-Level Study Of The Predictors Of Family-Supportive Supervision, Ginger Charmagne Hanson

Dissertations and Theses

There is a growing awareness that informal supports such as family-supportive supervision are critical in assuring the success of work-life policies and benefits. Furthermore, it is believed that family-supportive supervision may have positive effects regardless of the number or quality of work-life polices and benefits an organization has in place. Given this recognition, work-life experts have emphasized the need for supervisor training to increase family-supportive supervision. To date however, there has been a paucity of research on the predictors of family-supportive supervision which could be used as the target of such a training intervention. This dissertation had three major aims: …

An Investigation Of The Relationships Between Violence Exposure, Internalizing And Externalizing Problems, And Adolescent Alcohol Use, Gregory Lloyd Forehand Jan 2011

An Investigation Of The Relationships Between Violence Exposure, Internalizing And Externalizing Problems, And Adolescent Alcohol Use, Gregory Lloyd Forehand

Dissertations and Theses

Adolescent Alcohol Use (AAU) is widespread and potentially harmful to the health of youth. Substantial research and theoretical development suggest that both violence exposure and internalizing and externalizing problems of adolescents are associated with AAU. The primary purpose of this study was to examine the roles of internalizing and externalizing problems in adolescents to determine if the two types of symptoms are differential mediators of the link between violence exposure and AAU for females and males. Using Developmental Systems Theory as a framework, three primary hypotheses were examined: 1) Increased violence exposure at home and in the community are associated …

An Exploration Of Heterogeneous Networks On Chip, Allen Gary Grimm Jan 2011

An Exploration Of Heterogeneous Networks On Chip, Allen Gary Grimm

Dissertations and Theses

As the the number of cores on a single chip continue to grow, communication increasingly becomes the bottleneck to performance. Networks on Chips (NoC) is an interconnection paradigm showing promise to allow system size to increase while maintaining acceptable performance. One of the challenges of this paradigm is in constructing the network of inter-core connections. Using the traditional wire interconnect as long range links is proving insufficient due to the increase in relative delay as miniaturization progresses. Novel link types are capable of delivering single-hop long-range communication. We investigate the potential benefits of constructing networks with many link types applied …

On The Effect Of Topology On Learning And Generalization In Random Automata Networks, Alireza Goudarzi Jan 2011

On The Effect Of Topology On Learning And Generalization In Random Automata Networks, Alireza Goudarzi

Dissertations and Theses

We extend the study of learning and generalization in feed forward Boolean networks to random Boolean networks (RBNs). We explore the relationship between the learning capability and the network topology, the system size, the training sample size, and the complexity of the computational tasks. We show experimentally that there exists a critical connectivity Kc that improves the generalization and adaptation in networks. In addition, we show that in finite size networks, the critical K is a power-law function of the system size N and the fraction of inputs used during the training. We explain why adaptation improves at this critical …

Emotion Language And Emotion Narratives Of Turkish-English Late Bilinguals, Melike Yücel Koç

Dissertations and Theses

The primary focus of this research was to investigate the emotion language and emotion narratives of Turkish-English late bilinguals who have been living in the U.S. Previous research has shown that the emotion language and narratives of second language learners and native speakers of English are different. This study focused on late bilinguals who had learnt English in instructed settings in their home country, and came to the U.S. for M.A. and Ph.D. degrees. The study consisted of two parts. In the first part, the elicited personal narratives of Turkish-English late bilinguals in English were compared to those elicited from …

Closed Loop Satisfaction Measurement: New Wine From Old Bottles, Michael Thomas O'Connell Jan 2011

Closed Loop Satisfaction Measurement: New Wine From Old Bottles, Michael Thomas O'Connell

Dissertations and Theses

A field experiment examines within a financial services firm the impact of a customer satisfaction survey-based intervention that enables front-line employees to identify and contact less-than satisfied customers (less than 9 on a 10-point scale) to proactively prevent potential customer defections. The impact is measured using operational data from 28,000 new customers and their associated defection behavior over a period of eight years. The experiment applies binomial Z-tests of proportions to assess the difference in defection rates of targeted and non-targeted customers before and after the intervention. The research finds that the use of closed loop satisfaction measurement reduces customer …

Coupled Pedagogy: A Study Of Sustainability Education And Community-Based Learning In The Senior Capstone Program At Portland State University, Emily Erin Bowling Jan 2011

Coupled Pedagogy: A Study Of Sustainability Education And Community-Based Learning In The Senior Capstone Program At Portland State University, Emily Erin Bowling

Dissertations and Theses

Sustainability has emerged in mainstream higher education over the last few years, and the fields of community-based learning and sustainability education are closely linked through their emphases on active, experiential learning in place-based contexts. In order to create ecologically literate citizens to more adequately address environmental problems, there is a logical connection between teaching about sustainability and engaging students in the community, which can serve as a relevant forum to address sustainability issues. However, there is a problem in that educational programs and courses dealing directly with sustainability topics across the higher education landscape often do not emphasize or include …

Scaffolding The Development Of Early Self-Regulation: The Role Of Structure And Routine In Children's Daily Activities, Cynthia Lynn Taylor Jan 2011

Scaffolding The Development Of Early Self-Regulation: The Role Of Structure And Routine In Children's Daily Activities, Cynthia Lynn Taylor

Dissertations and Theses

Learning to self-regulate one's behavior is a core developmental task in early childhood. Regulation of behavior is a challenge for young children largely due to cognitive constraints, specifically in the areas of attention and memory. As such, it has been theorized that both caregivers and a child's environment can support the development of behavioral self-regulation by providing cues as to what constitutes acceptable behavior in any given context. Although much research has been conducted on the role caregivers play in this regard, little is known about how a child's environment may also serve to support emerging self-regulation of behavior. The …
