A Validated Tropical-Extratropical Flood Hazard Assessment For New York Harbor, Philip M. Orton, T. M. Hall, Stefan A. Talke, Alan F. Blumberg, Nickitas Georgas, S. Vinogradov

Civil and Environmental Engineering Faculty Publications and Presentations

Recent studies of flood risk at New York Harbor (NYH) have shown disparate results for the 100 year storm tide, providing an uncertain foundation for the flood mitigation response after Hurricane Sandy. Here we present a flood hazard assessment that improves confidence in our understanding of the region's present-day potential for flooding, by separately including the contribution of tropical cyclones (TCs) and extratropical cyclones (ETCs), and validating our modeling study at multiple stages against historical observations. The TC assessment is based on a climatology of 606 synthetic storms developed from a statistical-stochastic model of North Atlantic TCs. The ETC assessment …

Ph-Dependent Fluorescent Probe That Can Be Tuned For Cysteine Or Homocysteine, Yongkang Yue, Fangjun Huo, Xiaoqi Li, Ying Wen, Tao Yi, James C. Salamanca, Jorge O. Escobedo, Robert Strongin, Caixia Yin

Chemistry Faculty Publications and Presentations

The very close structural similarities between cysteine and homocysteine present a great challenge to achieve their selective detection using regular fluorescent probes, limiting the biological and pathological studies of these two amino thiols. A coumarin-based fluorescent probe was designed featuring pH-promoted distinct turn-on followed by ratiometric fluorescence responses for Cys and turn-on fluorescence response for Hcy through two different reaction paths. These specific responses demonstrate the activity differences between Cys and Hcy qualitatively for the first time. The probe could also be used for Cys and Hcy imaging in living cells.

Accommodating Faculty Requests And Staying True To Your Pedagogical Ideals In The 1-Shot Information Literacy Session, Rachel Scott

Communications in Information Literacy

Librarians are frequently asked to "teach" several databases in a 1-shot session, despite findings suggesting that such database demonstrations do not lead to optimal student outcomes. The ACRL Framework for Information Literacy for Higher Education highlights the concepts of metaliteracy and metacognition. This paper investigates ways in which I leveraged both of these concepts to reconcile my pedagogical ideals with an attempt to honor a faculty member's request. By demonstrating question posing and making my own metacognitive processes transparent to students, I found that I could honor a faculty request for specific database demonstration while helping learners comprehend and see …

Merging Information Literacy And Evidence-Based Practice In An Undergraduate Health Sciences Curriculum Map, Susan Franzen, Colleen Bannon

Communications in Information Literacy

The ACRL's Framework for Information Literacy for Higher Education offers the opportunity to rethink information literacy teaching and curriculum. However, the ACRL's rescinded Information Literacy Competency Standards for Higher Education correlate with the preferred research and decision-making model of the health sciences, evidence-based practice. Through a partnership, librarians and faculty can use all three to develop a curriculum map composed of a series of research assignments and library instruction delivered over the course of a two-year undergraduate allied health program. The presented curriculum map shows that the Standards can be retained and utilized as a bridge between the new Framework …

Reading For Integration, Identifying Complementary Threshold Concepts: The Acrl Framework In Conversation With Naming What We Know: Threshold Concepts Of Writing Studies, Brittney Johnson, I. Moriah Mccracken

Communications in Information Literacy

In 2015, threshold concepts formed the foundation of two disciplinary documents: the ACRL Framework for Information Literacy (2015) and Naming What We Know: Threshold Concepts of Writing Studies (2015). While there is no consensus in the fields about the value of threshold concepts in teaching, reading the six Frames in the ACRL document alongside the threshold concepts of writing studies illuminates overlapping elements that may empower faculty in both fields to advocate collectively against skills-focused writing and research instruction through cross-disciplinary integrations. To facilitate cross-disciplinary conversations around the documents, the authors propose an order for reading the Frames, identify the …

Do People Overestimate Their Information Literacy Skills? A Systematic Review Of Empirical Evidence On The Dunning-Kruger Effect, Khalid Mahmood

Communications in Information Literacy

This systematic review has analyzed 53 studies that assessed and compared peoples' self-reported and demonstrated information literacy skills. The objective was to collect empirical evidence on the existence of Dunning-Kruger Effect in the area of information literacy. The findings clearly show that this theory works in this area. It is concluded that there is no calibration in peoples' perceived and actual IL skills. In most of the cases, low-performers overestimate their skills in self-assessments. The findings have theoretical and practical implications for librarians and IL educators.

Designing For Engagement: Using The Addie Model To Integrate High-Impact Practices Into An Online Information Literacy Course, Amanda Nichols Hess, Katie Greer

Communications in Information Literacy

In this article, the authors share how a team of librarians used the ADDIE instructional design model to incorporate best practices in teaching and learning into an online, four-credit information literacy course. In this redesign process, the Association of American Colleges and Universities' high-impact practices and e-learning best practices were integrated as scaffolds for course content. The authors' experience with this systematic process and the concepts of instructional design suggest that the ADDIE model can be used to achieve several different ends in information literacy instruction. First, it can provide a structure around which librarians can develop a variety of …

Beyond The Hyperbole: Information Literacy Reconsidered, Heidi Julien

Communications in Information Literacy

Information literacy, as a concept, has suffered from terminological confusion and has been burdened with untenable expectations. In addition, insufficient attention has been given to the place of information with the context of information behavior or information practices generally. Significant challenges remain to developing information literacy, but its value remains relevant.

Manufacturing Consent In The Maghreb: How Mohammed Vi Of Morocco Survived The Arab Spring, David Michael Duke Ii

Dissertations and Theses

The Arab Spring of 2011 revealed stark variation in the durability of different types of authoritarian regimes. Kings and emirs demonstrably outperformed their republican peers. This paper provides a qualitative study of the Moroccan monarchy in order to better explain this pattern. The findings of an original media content analysis support the paper's thesis that Morocco's King Mohammed VI maintained his throne by effectively using a historically derived position of concentrated power and immense wealth to manipulate potential opposition and dominate public discourse. This multi-causal mechanism of manufactured consent helped create and sustain the monarch's domestic legitimacy while alienating his …

An Orphanage In Mexico: Four United Nations' Human Rights Of Children And Wolins' Prerequisites For Efficient Group Care Through The View Of The Manager And Staff, Lucia Beatriz Quesnel Galván

Dissertations and Theses

In Mexico there are officially 1.8 million orphaned children, without counting non-orphaned children deprived of family, who also need care; of these, only 657,000 are living in 703 orphanages. Mexico's government invests less than 2% of its budget toward protection of children. There is a lack of substantive research or official assessment of orphanages. According to the scant research found, the children's human rights most frequently violated in Mexican orphanages are the rights to nutrition and health care, to be protected from further victimization, to free expression and participation, and to not be exploited. This study was carried out through …

The Effects Of Frequency Of Social Interaction, Social Cohesion, Age, And The Built Environment On Walking, Gretchen Allison Luhr

Dissertations and Theses

The purpose of this dissertation was to explore, through a social ecological framework, the multifaceted effects of the neighborhood environment by investigating how dimensions of both the built environment and the neighborhood social context may interact to influence walking. Aesthetics, land use mix, crime, and pedestrian infrastructure were considered with respect to built environment walkability, and the neighborhood social context was conceptualized using measures of both social cohesion and social interaction with neighbors. This research used data from an Environmental Protection Agency (EPA)-funded study of 748 adults (18 years of age and older) residing in the Lents neighborhood in Portland, …

OHSU-PSU School of Public Health Faculty Publications and Presentations

Background -Interventions based around objective measurement of adherence to antiretroviral drugs for HIV have potential to improve adherence and to enable differentiation of care such that clinical visits are reduced in those with high adherence. It would be useful to understand the approximate upper limit of cost that could be considered for such interventions of a given effectiveness in order to be cost effective. Such information can guide whether to implement an intervention in the light of a trial showing a certain effectiveness and cost.

Methods - An individual-based model, calibrated to Zimbabwe, which incorporates effects of adherence and resistance …

Formulation Of Colloidal Suspensions Of 3-Mercaptopropionic Acid Capped Pbs Quantum Dots As Solution Processable Qd "Inks" For Optoelectronic Applications, Chase Collier Reinhart

Dissertations and Theses

The use of colloidal quantum dots (QDs) for photovoltaic energy conversion is a nascent field that has been dominated for well over a decade by the use of 3-mercaptopropionic acid (3-MPA) capped PbS QDs. These QDs are routinely deposited via an in situ solid state ligand exchange process that displaces the native oleate ligand on the PbS QD surface. This ligand exchange procedure is wasteful of material and has been demonstrated to leave numerous impurities that limit electronic performance of the as-deposited QD devices. Until the last few years there was very little understanding in chemical literature as to many …

A Multi-Agent System For Adaptive Control Of A Flapping-Wing Micro Air Vehicle, Michal Podhradský

Dissertations and Theses

Biomimetic flapping-wing vehicles have attracted recent interest because of their numerous potential military and civilian applications. In this dissertation is described the design of a multi-agent adaptive controller for such a vehicle. This controller is responsible for estimating the vehicle pose (position and orientation) and then generating four parameters needed for split-cycle control of wing movements to correct pose errors. These parameters are produced via a subsumption architecture rule base. The control strategy is fault tolerant. Using an online learning process, an agent continuously monitors the vehicle's behavior and initiates diagnostics if the behavior has degraded. This agent can then …

Algorithm For Premature Ventricular Contraction Detection From A Subcutaneous Electrocardiogram Signal, Iris Lynn Shelly

Dissertations and Theses

Cardiac arrhythmias occur when the normal pattern of electrical signals in the heart breaks down. A premature ventricular contraction (PVC) is a common type of arrhythmia that occurs when a heartbeat originates from an ectopic focus within the ventricles rather than from the sinus node in the right atrium. This and other arrhythmias are often diagnosed with the help of an electrocardiogram, or ECG, which records the electrical activity of the heart using electrodes placed on the skin. In an ECG signal, a PVC is characterized by both timing and morphological differences from a normal sinus beat.

An implantable cardiac …

This study examined the dynamics and perceptions of groups of ESL students who used wikis to write collaborative short stories. The study also compared the short stories written in groups with posttest short stories written individually in terms of creativity, accuracy, and complexity. The study involved nine students taking a Creative Writing course in an intensive English program at a large university in the U.S. It followed a multiple case study design; the students were divided into …

The Effectiveness Of Participation In A Project-Based Learning Project On At-Risk Student Self-Efficacy, Benjamin Aaron Weber

Dissertations and Theses

Project-based learning is a multifaceted approach to teaching in which students explore real-world problems and challenges while working in small collaborative groups. Project-based learning is active and engaging and drives students to obtain a deeper knowledge of the subjects they're studying, and students develop confidence and self-direction as they move through both team-based and independent work. This project endeavored to assess the effect of participation in a project-based learning (PBL) activity of the Wind and Oar Boat School's curriculum on the self-efficacy of at-risk high school students. Twenty students participated in the program for both math and applied arts credits …

A Meta-Analysis Of The Nomological Network Of Work Ability, Grant Brady

Dissertations and Theses

As the workforces of industrialized countries around the world continue to age, research is needed to better understand how policies regarding retirement, and exit from the workforce, impact older workers. In particular, it is important to identify mechanisms that can be used to understand and promote the retention of older workers. Work ability (WA), a construct that has been predominately studied in Scandinavian and European countries, has been studied in this context, and identified as a predictor of exit from the workforce. Using the Job Demands-Resources model (JDR; Demerouti, Bakker, Nachreiner, & Schaufeli, 2001) as the theoretical basis, the goal …

Understanding The Importance Of Intermittently Fragmented Stream Habitat For Isolated Westslope Cutthroat Trout (Oncorhynchus Clarki Lewisi) In The Colville National Forest, Washington, Forrest Michael Carpenter

Dissertations and Theses

Climate change and anthropogenic effects have vastly reduced Westslope Cutthroat Trout (Oncorhynchus clarki lewisi, WCT) habitat throughout their range, including the Colville National Forest in northeastern Washington where this study was conducted. Many native salmonid populations have declined in abundance since the early 1900s due to a variety of climate- and human-driven forces. Westslope Cutthroat Trout are especially sensitive to habitat loss or degradation and to climate change. Together, climate change, habitat degradation, and non-native salmonid invasions are contributing to increasingly fragmented WCT populations. Ongoing and predicted future warming trends are expected to further fragment these populations and …

Vulnerability And Protective Factors Of Stress-Related Drinking: An Exploration Of Individual And Day-Level Predictors Of Alcohol Involvement, Cameron Trim Mccabe

Dissertations and Theses

Problem alcohol use has far-reaching economic, intra-, and interpersonal consequences. One particularly hazardous form of drinking pertains to the consumption of alcohol as a means of regulating stress, or drinking to cope. As such, it is critical to identify pathways through which stress-related alcohol use occurs, as well as protective factors which may mitigate the aforementioned consequences. To achieve this, I conducted three studies examining these topics at multiple levels of analysis among two at risk populations for engaging in problematic drinking: College students and military service members. Study 1 is a published manuscript examining the association between personality, a …

Investigations Into The Effects Of Water Exchange And The Structure Of Lanthanide Chelates, Katherine Marie Payne

Dissertations and Theses

Lanthanide chelates are effective agents for improving contrast in MR images. Optimizing the relaxation of inner sphere water molecules is a common focus of research in this field. However, the efforts to design an optimal contrast agent have commonly over-looked the relationship of water position and water exchange kinetics. This work explores structural conformation, the impact of very fast water exchange kinetics on hydration, and differing tumbling rates for regioisomers of a number of lanthanide chelates. We have grown crystals of LnDOTMA and obtained structural data by X-ray diffraction that provide a picture of the chelate during water exchange and …

Pricing And Reliability Enhancements In The San Diego Activity-Based Travel Model, Joel Freedman

PSU Transportation Seminars

The estimation of demand for priced highway lanes is becoming increasingly important to agencies seeking to improve mobility and find alternative revenue sources for the provision of transportation infrastructure.

However, many modeling tools fall short of what is required for robust estimates of demand with respect to toll and managed lanes in two key areas:

• The value-of-time is often aggregate and not consistently defined throughout the model system, and
• The reliability of transport infrastructure is rarely taken into account.

This presentation describes an effort which implemented recommendations of the Strategic Highway Research Program C04 and L03\L04 tracks on pricing and …
