Product Popularity Versus Size Of Conversation In Social Media: An Analysis Of Twitter Conversations About Youtube Product Categories, Nitin Mayande, Charles Weber

Engineering and Technology Management Faculty Publications and Presentations

It has always been assumed that a large conversation about a topic on social media implies that the topic is popular. However, an empirical study of Twitter conversations about a variety of YouTube product categories, which is described in this paper, has shown that this is not necessarily the case. Popularity as measured by distribution volume is not necessarily a reliable indicator of the size of a community or conversation that is associated with a product category. This suggests that current online marketing practices are not nearly as effective as has been assumed to date. Novel, potentially more effective approaches …

Novel Approach To Managing Technological Entrepreneurship Using A Model-Based Systems Approach To Develop Low Cost Earth Orbiting Satellites, Gary Langford, Jeffery Carpenter, Ian Watkins, Brock Marsh, Lucas Beaulieu

Engineering and Technology Management Faculty Publications and Presentations

The ability to send low cost satellites into space has changed the satellite industry and vastly opened up the use of satellites to transform data into information for individuals, organizations, commercial companies, and governments. This information can be corroborated with other sources of data to evaluate the availability of precious resources, e.g., potable water, agriculture; to forecast upcoming famines or diseases; and to perform mapping, communications, and competitive analyses. The cost of owning a satellite is less than 100,000(usingcommercialparts)to1,000 (built by school kids). Launch costs are tens of thousands of dollars, which can be eliminated through subsidies. Compare these costs …

Assessing Photovoltaic Solar Technologies As A Solution For The Problem Of Power Shortage In Iraq, Ahmed A. Alibage

Engineering and Technology Management Faculty Publications and Presentations

In a developing country like Iraq, where the infrastructure of the electricity public sector (production, transportation, and distribution) has suffered for a long time from the direct effects of successive wars; lack of technocracy; bureaucracy; neglect; massive corruption; and much more, have all contributed to the failure of this sector. Indeed, the electricity sector in Iraq has not been developed for more than forty years; or even properly rehabilitated and/or maintained its facilities, which has led to a huge gap between the demand and supply (demand is double than the supply). It is obvious that the alternative solutions that have …

A Decision Model For Data Mining Techniques, Maoloud Dabab, Mike Freiling, Nayem Rahman, Daniel Sagalowicz

Engineering and Technology Management Faculty Publications and Presentations

Data mining is the process of extracting useful information from very large data sources. Data mining techniques have proven to be very useful in many domains. However, there is no single algorithm or technique that works best across all types of datasets and problems, and it remains "an art" to decide what data mining technique to use for a specific situation. This paper surveys several data mining techniques that can be applied to different business problems, and presents a decision model in the form of a series of 15-20 questions that help identify the best approach or approaches to a …

Business Intelligence And Data Analytics As A Driver Of Dynamic Capability Strategic Approach, Maoloud Dabab, Charles Weber

Engineering and Technology Management Faculty Publications and Presentations

Papers addressing the Dynamic Capability (DC) approach either support it as the best strategy or express its defects and impediments to implementation. However, this paper aims to promote the DC through the means of digital transformation from the angle of Business Intelligence and Data Analytics (BIDA). This article employs the logic of matching the essential components of the DC and BIDA to verify the extent of their conformity. A literature review methodology has been adopted since there are a considerable number of publications that focus on DC and BIDA. This paper posits that the main components of DC are sensing …

Internalized Hiv Stigma, Art Initiation And Hiv-1 Rna Suppression In South Africa: Exploring Avoidant Coping As A Longitudinal Mediator, Valerie A. Earnshaw, Laura M. Bogart, Jean-Philippe Laurenceau, Brian T. Chan, Brendan G. Maughan-Brown, Janan Dietrich, Ingrid Courtney, Gugu Tshabalala, Catherine Orrell, Glenda E. Gray, David Bangsberg, Ingrid T. Katz

OHSU-PSU School of Public Health Faculty Publications and Presentations

Introduction: Cross‐sectional evidence suggests that internalized HIV stigma is associated with lower likelihoods of antiretroviral therapy (ART) initiation and HIV‐1 RNA suppression among people living with HIV (PLWH). This study examined these associations with longitudinal data spanning the first nine months following HIV diagnosis and explored whether avoidant coping mediates these associations.

Methods: Longitudinal data were collected from 398 South African PLWH recruited from testing centres in 2014 to 2015. Self‐report data, including internalized stigma and avoidant coping (denying and distracting oneself from stressors), were collected one week and three months following HIV diagnosis. ART initiation at six months and …

Social marketing is a useful transportation demand management (TDM) planning approach to promote travel-behavior change. The purpose of this study was to explore a consumer market segmentation technique (SEGMENT) successfully used in Europe for its applicability to social marketing campaigns in the United States. Major contributions of this project are the validation of a successful existing segmentation technique for applicability in the United States, which will maximize the impact of TDM social marketing campaigns on …

Repatriation Of Afghan Refugees From Iran: A Shelter Profile Study, Mitra Naseh, Miriam Potocky, Paul Stuart, Sara Pezeshk

School of Social Work Faculty Publications and Presentations

One in every nine refugees worldwide is from Afghanistan, and Iran is one of main host countries for these refugees. Close to 40 years of hosting Afghan refugees have depleted resources in Iran and resulted in promoting and sometimes forcing repatriation. Repatriation of Afghan refugees from Iran to Afghanistan has been long facilitated by humanitarian organizations with the premise that it will end prolonged displacement. However, lack of minimum standards of living, among other factors such as private covered living area, can make repatriation far from a durable solution. This study aims to highlight the value of access to shelter …

Thermal Management In 3d Ic Designs For Nano-Cmos Technologies: Analysis On Graphene- Vs. Graphite-Based Tim, Satya K. Vendra, Malgorzata Chrzanowska-Jeske

Electrical and Computer Engineering Faculty Publications and Presentations

With a high thermal conductivity of 3000-5000 W/m-K, Graphene outstands almost all materials in effective lateral heat spreading. Will introduction of 2D monolayer graphene in 3D-IC help in vertical heat conduction too? In this work, we investigate the impact of Graphene- and Graphite- -based inter-die thermal interface material (TIM) on the peak temperature of the 3D-IC. We compare configurations of additional intermediate layer (IL) of monolayer graphene, graphite and copper materials along with TIM. Simulations show a peak temperature reduction of up to 500C in GSRC benchmarks. Role of thermal conductivity and the additional IL critical thickness in peak temperature …

Removal Efficiencies, Uptake Mechanisms And Competitive Effects Of Copper And Zinc In Various Stormwater Filter Media, Emily Heleva-Ponaski

Dissertations and Theses

Polluted stormwater, if not treated, can compromise water quality throughout our hydrologic cycle, adversely affecting aquatic ecosystems. Common stormwater pollutants, copper and zinc, have been identified as primary toxicants in multiple freshwater and marine environments. For small-scale generators, stormwater management can be cumbersome and implementation of common BMPs impractical thus catch basins are popular though not the most environmentally conscious and sustainable option. This study aims to characterize the potential of a mobile media filter operation for the treatment and on-site recycling of catch basin stormwater. The removal capacities of various commercially available filter media (e.g. a common perlite; Earthlite™, …

Online Learners: A Study Of Their Advising Attitudes, Experiences, And Learning, Stephen Philip Jenkins

Dissertations and Theses

Academic advising for online learners has been identified in prior research as an important student service. However, little research exists to assist advisers in knowing how best to serve this growing group. The purpose of this study is to close that research gap by determining if and how online and on-campus learners differ in how they rate the importance of various functions of academic advising as well as determining if their frequency of access to academic advising and source of advising information differed. Additionally, the research examines if the types and levels of learning for online learners varied by frequency …

Sons Et Lettres: A Pronunciation Method For Intermediate-Level French, Stephen Walton

PDXOpen: Open Educational Resources

Sons et lettres provides a set of classroom materials to train students to hear and produce the sounds of French and to recognize the regular spellings used to represent those sounds in print. The materials are inspired by a desire to help students feel more confident about their French pronunciation and more at home saying the many French words, familiar and unfamiliar, which they encounter in their studies, in French media and in their travels. In our experience, students are not given sufficient preparation to successfully decipher and pronounce French words. These materials are intended to fill that gap and …

Engaging Extended Family And Friends In Young Children’S Education, William A. Parnell, Ellie Justice, Laure Pearson Patrick

Education Faculty Publications and Presentations

Currently in our Reggio-inspired lab school, we continue experimenting with ways to connect extended family and friends to the school’s everyday practices, curricula, and philosophy. One approach that has been particularly valuable is our annual Friends and Family Day. This opportunity for engagement is not simply a demonstration of what and how the children have been learning—it is an event in which we all learn together. Friends and Family Day includes hands-on curriculum-based events in which children’s relatives and friends join in theory building, experimentation, and learning at our school (Parnell 2011b). We see such events as a way for …

Improving The Candidate Experience: Tips For Developing 'Wise' Organizational Hiring Interventions, Julie M. Mccarthy, Talya N. Bauer, Donald M. Truxillo, Michael C. Campion, Chad H. Van Iddekinge, Michael A. Campion

Business Faculty Publications and Presentations

Organizations that focus on ensuring a high-quality candidate experience are more likely to attract, engage, and connect with top talent. They are also able to bring more visibility to their brand. This is because when individuals feel connected to an organization, their attitudes and behaviors are more positive. As such, it is critical to ensure that the selection process candidates experience is a positive one. Indeed, a 2017 review of the applicant reactions literature was conducted by McCarthy and colleagues, and findings indicated that when candidates have a negative reaction to the selection process they are likely to report lower …

Giving The Noose The Slip: An Analysis Of Female Murderers In Oregon, 1854-1950, Jenna Leigh Barganski

Dissertations and Theses

Analyzing the crimes of women murderers and how they fared in the criminal justice system demonstrates that though perceptions of gender evolved, resistance to sentencing women to death often persisted. The nature of homicides committed by women in Oregon set them apart from their male counterparts. Women were, and are, more likely to commit domestic homicides -- murders that involve a family member or partner. These crimes are typically not equated with crimes that warrant capital punishment. As a result, no woman has been subjected to the death penalty in the state.

This thesis analyzes the twenty-five women who were …

How Can Community Engagement In The Local Past And Archaeological Research Be Mutually Beneficial? A Case Study In Community Archaeology From Sauvie Island, Oregon, Martin John Plumer

Dissertations and Theses

Community archaeology's broader objectives include increasing public understanding of archaeology and making archaeology more relevant to people's day to day lives. Fulfilling these goals could be beneficial to the public in terms of their gaining more agency in, and more access to, archaeology; and it could be beneficial to archaeologists in terms of increasing public support for archaeological work. While many community archaeologists report success, few authors critically evaluate the experience and outcomes of community archaeology. As a result, little data-based understanding exists about what is gained through community archaeology. This project explores that question through three primary means: 1) …

A Study Of Bus High-Resolution Gps Speed Data Accuracy, Miguel Figliozzi, Nicholas B. Stoll

Civil and Environmental Engineering Faculty Publications and Presentations

The recent availability of high-frequency transit (HFT) GPS data for buses has allowed the estimation of detailed bus-travel speed profiles between bus stops. HFT data are defined as data comprising GPS vehicle trajectory recorded at or less than 5 s intervals. With HFT data it is now possible to measure changes in bus speed at specific locations of interest, such as intersections, ramps, crosswalks, and so on. Previous research efforts have not compared GPS-based bus speeds with general traffic speeds at specific locations between stops. This research fills this knowledge gap, utilizing accurate stationary radar speed data as a baseline …
