Pre-Service Educators' Understanding And Perceptions Of Asd Before And After Reading Asd Narrative Fiction, Brenda L. Barrio, Jane E. Kelley, Teresa Cardon

Northwest Journal of Teacher Education

Pre-service teachers and other educators are expected to understand and teach students from diverse backgrounds and varying abilities. One group that is growing in all classrooms across the U.S. are students with autism spectrum disorder (ASD). As such, it is essential that teacher preparation programs prepare pre-service teachers and educators to teach students with ASD. The purpose of the research was to examine the effects of pre-service teachers understanding and perceptions about ASD before and after reading young adult literature about characters with ASD. Results of parallel mixed-method research showed an increase of positive attitudes of pre-service teachers and educators' …

The Impact Of Attending An Equity-Based Conference On One Teacher Educator: Five Pedagogical Changes Of Practice, Rebecca Smith

This article is a reflective overview of five pedagogical practice changes that one teacher educator made after attending a multicultural education conference. The article integrates current research to highlight the educational benefits of innovative, equity-based instructional strategies. The pedagogical changes are explored through the theoretical lens of culturally relevant pedagogy (Ladson-Billings, 1995; Gay, 2010) and culturally sustaining pedagogy (Paris & Alim, 2017) and include: diversifying curriculum, engaging with community partners, collaborating with K-12 practitioners, innovative technology, and self-reflection.

Perceptions Of Teacher-Writers: Initial Influences To Write, Shari L. Daniels, Pamela Beck

Northwest Journal of Teacher Education

This qualitative case study explores perceptions of teacher-writers’ early writing histories and examines their initial influences to write. Interviews and writing artifacts of ten K-12 teacher-writers serve as the primary data source. Findings indicate that teachers with strong identities as readers and/or writers in their K-12 experiences often received positive feedback which encouraged them to develop as writers, while teachers challenged with mechanics often received negative feedback which discouraged them from writing. Revisiting negative writing histories reshaped writing beliefs to influence a positive writing identities. The authors suggest practices for pre-service literacy courses to examine writing histories and to develop …

A Study Of Sidewalk Autonomous Delivery Robots And Their Potential Impacts On Freight Efficiency And Travel, Dylan Jennings, Miguel A. Figliozzi

Civil and Environmental Engineering Faculty Publications and Presentations

E-Commerce and package deliveries are growing at a fast pace and there is an increased demand for same-day deliveries. Established delivery companies and new startups are investing in technologies that reduce delivery times and/or increase delivery drivers’ productivity. In this context, the adoption of Sidewalk Automated (or Autonomous) Delivery Robots (SADRs) has a growing appeal. SADRs are pedestrian sized robots that deliver items to customers without the intervention of a delivery person. Since SADRs travel on sidewalks they have been the subject of increasing regulation by local agencies in the US. The three research questions that guide this research effort …

Using Virtual Reality And Web Conferencing Technologies: Exploring Alternatives For Microteaching In A Rural Region, Raymond A. Dixon, Cassidy Hall, Farjahan Shawon

Northwest Journal of Teacher Education

Preservice teachers’ views of two types of technologies which provided realistic environments in which to practice microteaching are described: (1) TLE TeachLivE™ Lab, a virtual reality environment that employs avatars as students in a virtual classroom, and (2) web conferencing technology to synchronously teach students in remotely located classrooms. Preservice teachers opined that each technology offers a relatively realistic environment that allows them to interact with virtual and real students. Microteaching through these technologies increases their self-confidence and provided a safe, non-threatening environment for them to reflect on their practice. We concluded these emerging technologies can provide viable alternatives to …

Illuminating Social Justice In The Framework: Transformative Methodology, Concept Mapping And Learning Outcomes Development For Critical Information Literacy, Nicole A. Branch

Communications in Information Literacy

The intentional omission of learning outcomes from the ACRL Framework for Information Literacy in Higher Education has caused concern and criticism from some librarians; however, the call to action within the Framework to locally develop learning outcomes is an opportunity to illuminate the social justice, critical thinking, and higher order thinking elements of information literacy. This study applies the transformative research paradigm using the methodology of concept mapping to test the development of learning outcomes for one of the frames. Concept mapping is a mixed-methods approach and includes focus groups, hierarchical cluster analysis, and multidimensional scaling. The methodology has been …

Communications in Information Literacy

This study examines levels of library anxiety in 30 adult learners before and after completing a two-credit information literacy course. A modified version of the Multidimensional Library Anxiety Scale was administered at the beginning and end of the course to compare levels of library anxiety. An analysis of the data revealed that the course was moderately effective in reducing library anxiety in adult learners. Awareness of library resources, comfort with the search process, and comfort level with library technology significantly increased after course completion. No significant decreases in library anxiety were reported in the areas of comfort level with staff …

Reddit As An Analogy For Scholarly Publishing And The Constructed, Contextual Nature Of Authority, Anna M. White

Communications in Information Literacy

This paper provides an overview of how the social news site Reddit can be used as an example of the ACRL Framework for Information Literacy for Higher Education threshold concept “Authority is Constructed and Contextual.” It posits that the construction and context of authority in the sense of Wilson’s concept of cognitive authority is in the inherent structure of Reddit and that students can benefit from an example that easily links their personal and academic lives—a connection not always made when discussing authority in peer-reviewed publications or databases.

Homelessness Count Methodologies Literature Review, Jennifer Lee-Anderson

Homelessness Research & Action Collaborative Publications and Presentations

This literature review on homeless count methods provides a brief history of homelessness in the U.S., an account of count efforts, and an overview of methods used. It illustrates that no method is capable of providing a comprehensive count of the homeless, and all methods have inherent disadvantages that often rely upon flawed assumptions. The practical impact of these counts on policy is substantial. Therefore, this review should encourage discussion as to what data communities need for policy and program development and implementation, and whether homeless counts actually fulfill this need.

Understanding and addressing problematic narratives surrounding homelessness is one of the primary objectives of the Homelessness Research and Action Collaborative. We began to do this by mapping out different stakeholders and identifying texts such as social media posts, policy documents, and local news articles which reflect the language used by various groups to discuss and promote their concerns and beliefs about homelessness. Over 11,000 reports were analyzed.

Do Directionality And Network Size Affect Network Structure In Online Social Networks?, Nitin V. Mayande, Charles Weber

Engineering and Technology Management Faculty Publications and Presentations

A study of the online social networks of six Twitter conversations about six YouTube product categories reveals that directionality and network size affect the structure of online social networks. Our results indicate that large networks tend to be non-random, regardless of whether they are directional or not, suggesting that structural attributes of the online networks under study are a true reflection of network's features. Smaller non-directional networks also tend to be non-random, whereas smaller directional networks tend to be random in nature. However, very small networks tend to be random in nature, whether they are directional or not. Our results …

Many providers are responding to the unique developmental needs of this population by adapting the design and delivery of their services to better engage and retain young people in system of care supports. Overall, strategies include expansion of drop-in center programming, adaptations to practice models like Wraparound, and new outreach efforts using social media and other technologies. Our purpose here is to share some …

The Small Publisher’S Guide To Audiobooks, Stephanie Anderson

Book Publishing Final Research Papers

While audiobooks have been around since the invention of the phonograph, the invention of streaming technologies, combined with our increasingly fast-paced, multitasking culture, has caused audiobooks to become the fastest growing market in the publishing industry in recent years. In fact, since 2013 the audiobooks market has seen sales growth of an average of 20% per year, according to studies done by the Audio Publishers Association. However, many small publishers are not entering into the vital “new” frontier and reaching greater markets because of assumptions about the cost-prohibitive nature of creating audiobooks, and a lack of knowledge of the industry …

Context-Aware Synthesis For Video Frame Interpolation, Simon Niklaus, Feng Liu

Computer Science Faculty Publications and Presentations

Video frame interpolation algorithms typically estimate optical flow or its variations and then use it to guide the synthesis of an intermediate frame between two consecutive original frames. To handle challenges like occlusion, bidirectional flow between the two input frames is often estimated and used to warp and blend the input frames. However, how to effectively blend the two warped frames still remains a challenging problem. This paper presents a context-aware synthesis approach that warps not only the input frames but also their pixel-wise contextual information and uses them to interpolate a high-quality intermediate frame. Specifically, we first use a …

From Nativism To White Power: Mid-Twentieth-Century White Supremacist Movements In Oregon, Shane Burley, Alexander Ross

Geography Faculty Publications and Presentations

Two document cases in the Oregon Historical Society (OHS) Research Library's George Rennar papers contain significant documentation of White supremacist organizations that developed in Oregon during the period between World War I and World War II. In this Research Files article, Shane Burley and Alexander Reid Ross highlight connections found within the collection between the variety of interlinked, racist, and nationalist organizations during that time period. Burley and Ross argue that while “membership numbers remained relatively small, these organizations provided a crucial link to the development of radical right-wing groups during the postwar era.”

Affordances On Facebook, Stress, And Emotional Support, Caitlin Rose Rethwish

Dissertations and Theses

This study discusses Facebook as a social network site and a social media application. It compares perceived emotional support, general life stress, and media affordance-based stress from two participant samples - one that reported using the Facebook desktop site most frequently to reach out for emotional support, and one that reported using the mobile application.

The media affordance measure asked participants if perceiving a media affordance was more likely to increase or decrease their stress. In both samples, persistence was more likely to decrease stress, and personalization was more likely to increase stress. On the Facebook Desktop site, searchability was …

Capturing The Built Environment-Travel Interaction For Strategic Planning: Development Of A Multimodal Travel Module For The Regional Strategic Planning Model (Rspm), Liming Wang, Brian Gregor, Huajie Yang, Tara Weidner, Anthony Knudson

Urban Studies and Planning Faculty Publications and Presentations

Integrated land use and transportation models have evolved along a spectrum from simple sketch planning models to complex microsimulation models. While each has its niche, they are largely unable to balance the flexibility and realism of microsimulation and the speed and interactivity of simple models. The Regional Strategic Planning Model (RSPM) aims to fill this gap by taking a microsimulation approach while making other simplifications in order to model first-order effects quickly. It enables planners to consider the robustness of prospective policies in the face of future uncertainties by accepting a broad range of inputs and allowing rapid simulations of …

The Effect Of Styrene-Maleic Acid (Sma) Copolymers On Solubilizing Lipid Bilayers And Forming Nanodiscs, Ghada Alramadan

Dissertations and Theses

Cell membranes, or plasma membranes, play an essential role in the structure and the function of living cells. In 1972, the fluid mosaic membrane model was the first unifying paradigm of membrane structure. It is no longer considered adequate because evidence of many non-homogeneous lipid structures in both natural and model membranes have been discovered over the past thirty years. The field of membrane biophysics now uses updated versions of the mosaic model, which consists of the complex mixture of different lipid species. The lipid species found in natural membranes produce a range of dynamic, laterally segregated, non-homogeneous domains, which …

A Multicultural Approach To Digital Information Literacy Skills Evaluation In An Israeli College, Efrat Pieterse, Riki Greenberg, Zahava Santo

Communications in Information Literacy

Information literacy is an essential proficiency for success in academic studies, yet many first-year students find it hard to use information sources efficiently and to develop academic information literacy. This study reports findings from first-year students' self-estimation of their information skills according to two information literacy models (Shapiro & Hughes, 1996; Ng, 2012) and presents interesting insights on the differences between the multicultural and multilingual student groups in the study’s population. The researchers found that Hebrew-native speaking students preferred digital sources while Hebrew as second language (Arabic-speaking) students preferred printed sources, and both groups ranked their technological and information literacy …

Lifecycle Modeling And Assessment Of Unmanned Aerial Vehicles (Drones) Co2e Emissions, Miguel A. Figliozzi

Civil and Environmental Engineering Faculty Publications and Presentations

There are no studies that model the potential effectiveness of Unmanned Aerial Vehicles (UAVs) or drones to reduce CO2e lifecycle (including both utilization and vehicle phase) emissions when compared to conventional diesel vans, electric trucks, electric vans, and tricycles. This study presents a novel analysis of lifecycle UAV and ground commercial vehicles CO2e emissions. Different route and customer configurations are modeled analytically. Utilizing real-word data, tradeoffs and comparative advantages of UAVs are discussed. Breakeven points for operational emissions are obtained and the results clearly indicate that UAVs are more CO2e efficient, for small payloads, than conventional diesel vans in a …

Subjective Cognitive Functioning Relates To Parenting In Mothers With Chronic Pain, Denae S. Clohessy

University Honors Theses

Individuals with chronic pain commonly report problems with daily cognitive functioning. This feeling of decreased subjective cognitive functioning (SCF) can be distressing due to its impact on daily life and relationships. Children of parents with chronic pain are at an increased risk for the development of chronic pain and related impairment and it is possible that lower parental SCF could increase this risk. Specifically, mothers with lower SCF may have difficulty completing day-to-day caregiving activities as well as responding flexibly to children’s behaviors. The present study focused on examining the impact of SCF on parenting in mothers with chronic pain. …

Assessment Of Cooling And Heat Transfer Properties Of Quenchants With Matlab, Lemmy Meekisho, Rosa L. Simencio Otero, Jônatas M. Viscaino, D. Scott Mackenzie, George Totten, Lauralice C.F. Canale

Mechanical and Materials Engineering Faculty Publications and Presentations

There is ongoing interest for evaluating the potential of renewable base stocks, such as vegetable oils, to replace petroleum oils as metal quenchants. Perhaps the most critical part of this process is characterizing and comparing the cooling and heat transfer performance of potential quenchant candidates. In this work, cooling curves of two vegetable oils, palm oil and canola oil, were obtained along with a commercially available conventional and an accelerated petroleum quenchant using the so-called Tensi multiple thermocouple probe, with emphasis on the center probe emulating a small probe concept. The lumped-parameter approach was implemented in the MATLAB environment (Mathworks …

Working Paper No. 01, Three Forms Of Fascism, Lauren Sweger-Hollingsworth

Working Papers in Economics

This inquiry seeks to establish that fascism can appear in three forms. A classical fascist, a brutal and dominating figure, is autodidactic, having impressive and engaging oratory skills that effectively put forth their ideals to the working-class majority. Neo-fascists, or neo-Nazis, idolize Hitler and the society of Nazi Germany, being extremely radical and militant, they exist in small groups dispersed around the world. A post-modern fascist uses money and various forms of media to spread their ideologies to vulnerable members of society. Post-modern fascists project themselves as hard-working and tough, but they buy loyalty and pay others to do their …

Quenchant Cooling Curves, Rewetting, And Surface Heat Flux Properties Of Vegetable Oils, Rosa L. Simencio Otero, Jônatas M. Viscaino, Jun Xu, Jianfeng Wu, George Totten, Lauralice C.F. Canale

Mechanical and Materials Engineering Faculty Publications and Presentations

Vegetable oils are currently used for biodegradable and renewable base stocks for quenchant formulation. However, there are relatively few references relating to their true equivalency, or lack thereof, comparative to the quenching performance of petroleum oil-based quenchant formulations. To obtain an overview of the variability vegetable oil quenching performance, the cooling curves and rewetting properties were determined, and the surface heat flux properties were calculated. The vegetable oils that were studied included canola, coconut, corn, cottonseed, palm, peanut, soybean, and sunflower oils. Cooling curves were obtained using the Tensi multiple-surface thermocouple 15 mm diameter by 45 mm cylindrical Inconel 600 …
