Refreshing Information Literacy: Learning From Recent British Information Literacy Models, Justine Martin

Communications in Information Literacy

Models play an important role in helping practitioners implement and promote information literacy. Over time models can lose relevance with the advances in technology, society, and learning theory. Practitioners and scholars often call for adaptations or transformations of these frameworks to articulate the learning needs in information literacy development. This study analyzes four recently published models from the United Kingdom. The initial findings were presented in a report for an ACRL taskforce reviewing the Information Literacy Competency Standards for Higher Education. This article presents complementary, yet distinct findings from the same dataset that focus on reoccurring themes for information literacy …

Every Town Is All The Same When You've Left Your Heart In The Portland Rain: Representations Of Portland Place And Local Identity In Portland Popular Lyrics, Meghan Andrea Kearney

Dissertations and Theses

This study looks at how place and local identity of Portland are described within music lyrics from Portland, Oregon popular indie-rock artists. Employing a constant comparative analysis on a set of 1,201 songs from 21 different popular Portland indie-rock artists, the themes of landscapes and climate were found to represent place, and themes of lifestyles and attitudes represented local identity. Reviewing the uncovered themes showed a strong connection between representations of place and local identity within lyrics and common stereotypes or understandings of the city of Portland and its indie-rock music scene. The results of this study illustrate how place …

Sexting Unleashed: The Social Phenomenon According To Youth Sexters, Jessica Marie Mcgraw

Dissertations and Theses

What is missing from academia and society at large is a more holistic picture of youth sexting. Not adequately understanding youth sexting has stunted previous attempts to effectively educate young people on its potential consequences. As such, the social and legal consequences of sexting gone viral have negatively impacted countless individuals. This study offers a preliminary glimpse of the sexting phenomenon by highlighting the experiences of 20 young people. I explore emergent themes regarding the nature of youth sexting as well as the interrelations amongst privacy, relationships, and sexting. Two distinct forms of sexting emerged from participant narratives, opening the …

Factors Influencing Youth Self-Perceptions Of Overweight And Obesity, Caitlin Helen Sommers

Dissertations and Theses

This study sought to examine whether participation in physical activity affects the ability to correctly classify body size, based on body mass index classifications. Secondarily, this study determined whether adolescents who incorrectly classified their body size overestimated or underestimated their size. Self-report data from the Youth Risk Behavior Surveillance Survey collected by the Centers for Disease Control and Prevention were analyzed. Logistic regression was performed to examine relationships between self-perception of body size and physical activity, television viewing time, computer/video game use, physical education class time, and extracurricular sports activities. Significance was set to p<0.05. Physical activity was the only statistically significant independent variable (p=0.058, OR = 1.060). Although physical activity was shown to be statistically significant, it did not appear to meaningfully increase the ability of youth to correctly classify body size. Secondary analysis showed that adolescents who incorrectly classified their body size were more likely to underestimate their body size. Females more frequently underestimated their body size (females=673; males=384).

How Does Student Understanding Of A Concept Change Throughout A Unit Of Instruction? Support Toward The Theory Of Learning Progressions, Brian Jay Dyer

This study documented the changes in understanding a class of eighth grade high school-level biology students experienced through a biology unit introducing genetics. Learning profiles for 55 students were created using concept maps and interviews as qualitative and quantitative instruments. The study provides additional support to the theory of learning progressions called for by experts in the field. The students' learning profiles were assessed to determine the alignment with a researcher-developed learning profile. The researcher-developed learning profile incorporated the learning progressions published in the Next Generation Science Standards, as well as current research in learning progressions for 5-10th grade students …

Application Of Support Vector Machine In Predicting The Market's Monthly Trend Direction, Ali Alali

Dissertations and Theses

In this work, we investigate different techniques to predict the monthly trend direction of the S&P 500 market index. The techniques use a machine learning classifier with technical and macroeconomic indicators as input features. The Support Vector Machine (SVM) classifier was explored in-depth in order to optimize the performance using four different kernels; Linear, Radial Basis Function (RBF), Polynomial, and Quadratic. A result found was the performance of the classifier can be optimized by reducing the number of macroeconomic features needed by 30% using Sequential Feature Selection. Further performance enhancement was achieved by optimizing the RBF kernel and SVM parameters …

Exploring The Effects Of Multi-Level Protective And Risk Factors On Child And Parenting Outcomes In Families Participating In Healthy Start/Healthy Families Oregon (Hs/Hfo), Peggy Nygren

Dissertations and Theses

While many studies focus on the links between multiple risk factors and negative outcomes such as child maltreatment, less is known about the influence of protective factors in the face of risks. The theoretical base of this study was a social ecological model of interactive influences including individual parent, family, and neighborhood level factors to predict outcomes. Protective Factor Index (PFI) and Risk Factor Index (RFI) predictors were developed to explore potential multi-level protective factor buffering effects on key child development and parenting outcomes. Participants were first time mothers enrolled in a randomized controlled study of the Healthy Start/ Healthy …

A Theory Of Travel Decision-Making With Applications For Modeling Active Travel Demand, Patrick Allen Singleton

Dissertations and Theses

The continuing evolution of urban travel patterns and changing policy goals and priorities requires that transportation researchers and practitioners improve their abilities to plan and forecast the demand for travel. Walking and bicycling - the primary forms of active travel - are generating increasing interest for their potential to reduce automobile use, save governmental and consumer costs, and improve personal and social health outcomes. Yet, current transportation planning tools, namely regional travel demand forecasting models, poorly represent these active travel modes, if at all.

More broadly, travel models do an incomplete job of representing the decision-making processes involved in travel …

Work Stress Reactivity And Health Outcomes: A Study Of Nurses, Laurie Marie Jacobs

Dissertations and Theses

Negative events encountered in daily life influence individual well-being. Individuals vary in their reactivity to these events, the extent to which they are behaviorally, physiologically, and psychologically influenced by them (Almeida, 2005; Neupert, Almeida, & Charles, 2007). Reactivity to events in the form of changes in health behavior could represent either an attempt at coping (Cooper, Frone, Russell, & Mudar, 1995) or a stressor-related failure of self-control (Muraven & Baumeister, 2000). Such changes in behavior could have later effects on health.

Although a great deal of attention has been paid to both the immediate and long-term effects of stressors on …

Batterer Intervention Programs' Response To State Standards, Ashley Lynn Boal

Dissertations and Theses

The study of policy implementation has recently garnered research and federal attention highlighting the importance of implementation in achieving desired policy and program outcomes (Durlak & DuPre, 2008; Meyers, Durlak & Wandersman, 2012; National Institutes of Health, 2013). Psychology is one discipline that is well poised to guide the study of policy implementation as it can inform the creation, development, and outcomes associated with the introduction of a policy (Esses & Dovidio, 2011; Fischhoff, 1990). Given that batterer intervention programs (BIPs) have been developed to prevent future intimate partner violence (IPV) and improve victim safety, ensuring these programs have successfully …

Daily Mood-Drinking Slopes As Predictiors: A New Take On Drinking Motives And Related Outcomes, Cynthia D. Mohr, Deborah L. Brannan, Staci Jean Wendt, Laurie Marie Jacobs, Robert Randon Wright, Mo Wang

Psychology Faculty Publications and Presentations

Motivational models of alcohol consumption have articulated the manner in which positive and negative experiences motivate drinking in unique social contexts (e.g., Cooper, Frone, Russell & Mudar, 1995). Daily process methodology, in which daily events, moods and drinking behaviors are reported daily or multiple times per day, has been used to examine behavioral patterns that are consistent with discrete motivations. We advance the notion that repeated patterns of drinking in various social contexts as a function of positive or negative mood increases can provide evidence of individual-level if-then drinking signatures, which in turn can predict drinking-related outcomes. The purpose of …

I'M Not Gonna Be Like That Guy: Exploring The Montana Meth Project Through The Eyes Of That Guy, Jaysen Nicole Ferestad

Dissertations and Theses

Graphic images of meth addicts have swept across Montana in television, radio and print ads as part of the state's latest anti-drug campaign, the Montana Meth Project. From a labeling perspective, the negative portrayal of meth addicts in these ads has significant implications for meth addicts in terms of their reintegration. The unintended population of drug addicts potentially affected by public service campaigns has failed to gain attention in the literature despite the implications suggested by labeling theory. This poses a significant gap in our knowledge and understanding, which this study addresses through the voice of recovering meth addicts. This …

The Impacts Of Urban Renewal: The Residents' Experiences In Qianmen, Beijing, China, Yongxia Kou

Dissertations and Theses

The study examines the influences of the Qianmen urban renewal project on its original residents, which is one of a few demonstration projects under the new policy orientation of urban renewal practices in Beijing, China, entering the new century. It employs "residential satisfaction" as an evaluative indicator to understand the residents' experiences before and after urban renewal. Seventy-two residents were interviewed. Among them, 25 remained in Qianmen; 20 relocated to Hongshan, a neighborhood in the central city area; 21 moved to Longyue, a neighborhood in one of the suburban areas; and 6 residents relocated to other locations.

The study found …

"Do Not Disturb": A Micro-Macro Examination Of Intrusions At Work, Bing Chun Lin

Dissertations and Theses

Intrusions, or interruptions by others, are a common phenomenon in the modern workplace (Grove, 1983; Jett & George, 2003), particularly in the computing and information-technology (CIT) industry, as cross-specialty, and cross-team collaborations become more common (Beck et al., 2001). The present study examines the relationship between day-to-day intrusions (measured Monday, Tuesday, and Wednesday) and strain reactions and perceived job performance over the week (measured on Thursday) among 150 CIT employees. Using a number of resource-based theories (i.e., Conservation of Resources, Ego Depletion Model, Cognitive Fatigue Model), I hypothesize that participants experiencing more frequent intrusions on a day-to-day basis will experience …

Acceptance Of Disability And Its Predictors Among Stroke Patients In Taiwan, Shan-Yun Chiu, Hanoch Livneh, Long-Lung Tsao, Tzung-Yi Tsai

Counselor Education Faculty Publications and Presentations

Background: Modern medicine has increased the survival rate for stroke patients; however, the patient’s psychosocial adaptation after stroke onset may be related to the clinical outcomes. This study aimed to investigate patients’ acceptance of disability (AOD) and its predictors in stroke patients. Methods: This cross-sectional study used a purposive sampling method to recruit 175 stroke patients from a hospital in southern Taiwan. A structured questionnaire gathered data on respondent demographics and disease characteristics, and included the Chinese version of the AOD Scale-Revised. Factors associated with AOD were examined by a multiple linear regression analysis. Results: The mean AOD score was …

Fated To Pretend?: Culture Crisis And The Fate Of The Individual, Rebecca Jade Ok

Dissertations and Theses

The question of this thesis is whether the individual can resolve the problem of culture crisis in her own case. Culture crisis is a historical moment in which our culture leads us to expect a world drastically different from the one in which we find ourselves. This thesis will focus on the experience of Generation Y in the fall-out of the 2008 Recession. It will be argued that we need a Wittgensteinian view of language in order to account for the phenomenon of culture crisis. It will be suggested that our individual has to be a Nietzschean individual in order …

The Impacts Of Change In Governance On Faculty And Staff At Higher Education Institutions: A Case Study Of Ohsu, Dana L. Director

Dissertations and Theses

In the early 1990s, Oregon Health and Science University leadership examined the political and economic landscape and determined it needed a new operational model to survive and thrive. In 1995 OHSU separated from the state higher education system and became a public corporation, with goals of increased efficiency, customer-focus, ability to attract world-class researchers and physicians, and salaries commensurate with an urban academic health center.

This research examines the internal impacts when universities undergo significant change, using OHSU's governance change as a case study. Central is the question: what effect(s) did OHSU's decision to become a unique public corporation have …

A Unique Support For Sexual-Minority Identity Development: An Interpretative Phenomenological Analysis Of A Long-Term Formal Mentoring Relationship Between An Adult And A Youth From The Gay Community, Christian L. Rummell

Dissertations and Theses

An important need exists to build a baseline understanding of the phenomenon of formal mentoring relationships involving adults and youth from the gay community. During the formative years when gay adolescents navigate through the process of understanding, defining, accepting, and sharing their identity as a sexual minority, they are often faced with high levels of environmental risks, including victimization, stress, and negative social sanctions by others. Formal mentoring has been recommended as a potential strategy to offer unique one-to-one support to gay youth that can help to foster resilience and a range of positive outcomes, including strengthening processes involved in …

From Transit Stop To Urbanity Node: Field Audit For Measuring Livability At The Transit Stop, Deni Ruggeri

TREC Final Reports

This research proposal addresses issues of livability at the transit stop. American transit systems have historically been “shoehorned” into existing street networks designed predominantly for cars and trucks. While much research exists on livability and walkability in the context of urban and suburban streets and blocks, bus stops are greatly understudied. This research focused on bus stops and aimed at analyzing their performance in terms of livability, with particular emphasis on perceptions. Our definition of livability was expanded to include considerations of safety and maintenance, cleanliness, imageability and vitality, which have been shown to affect people’s perceptions of livability and …

Willow: Reaching Hiv-Positive African-American Women Through A Computer-Delivered Intervention, Charles H. Klein

Anthropology Faculty Publications and Presentations

This study evaluates the efficacy of Multimedia WiLLOW in enhancing HIV-protective sexual behaviors and psychosocial outcomes among HIV-positive African American women, including condom use for vaginal and anal sex, and psychosocial mediators associated with risk reduction practices. Using a community-based randomized controlled design, 168 participants completed a baseline and follow-up assessment as well as an exit satisfaction survey. Intervention participants reported significantly higher proportions of condom protected sex acts in the past 30 days (p=.002), with both HIV-negative (p=.040) and HIV-positive (p=.003) partners. They were also more likely to report 100% condom use (OR = .10; p=.030); a lower adjusted …

Human Development Dynamics: An Agent Based Simulation Of Macro Social Systems And Individual Heterogeneous Evolutionary Games, Mark Abdollahian, Zining Yang, Travis Coan, Birol Yesilada

Political Science Faculty Publications and Presentations

Purpose: In the context of modernization and development, a complex adaptive systems framework can help address the coupling of macro social constraint and opportunity with individual agency. Combining system dynamics and agent based modeling, we formalize a simulation approach of the Human Development (HD) perspective to explore the interactive effects of economics, culture, society and politics across multiple human scales.

Methods: Based on a system of asymmetric, coupled nonlinear equations, we first capture the core qualitative logic of HD theory, empirically validated from World Values Survey (WVS) data. Using a simple evolutionary game approach, second we fuse endogenously derived individual …

Harnessing Poverty Alleviation To Reduce The Stigma Of Hiv In Sub-Saharan Africa, Alexander C. Tsai, David Bangsberg, Sheri D. Weiser

OHSU-PSU School of Public Health Faculty Publications and Presentations

HIV is highly stigmatized throughout sub-Saharan Africa. In studies conducted among general population samples, stigma has been shown to impede uptake of HIV testing and increase sexual risktaking behavior. Among HIV-infected persons, stigma has also been associated with inhibited serostatus disclosure to sexual partners and potential treatment supporters, delays in HIV antiretroviral therapy (ART) initiation, and ART nonadherence. The stigma of HIV also intensifies the poverty, stress, and insecurity endemic to many resource-limited settings, resulting in worsened mental health, itself an important determinant of AIDS-related mortality. Until we can better understand how to effectively intervene to reduce the stigma of …

Putting The Heart Back Into Writing: Nurturing Voice In Middle School Students, Barbara Ruben, Leanne Moll

Curriculum and Instruction Faculty Publications and Presentations

To gain a deeper understanding of young adolescent motivation and developmental needs as the nation plunges ahead with the national Common Core Standards and their implications for writing instruction, the authors of this article pondered five questions as they studied their own middle school writing team: (1) What intrinsic motivators drive these young students to write? (2) What components create a nurturing writing environment? (3) How can we understand student motivation so that we can nurture student interest in writing within the constraints of large classes and mandates to address Common Core Standards? (4) For students who are already intrinsically …

Increased Risk And Related Factors Of Depression Among Patients With Copd: A Population-Based Cohort Study, Tzung-Yi Tsai, Hanoch Livneh, Ming-Chi Lu, Pang-Yau Tsai, Pei-Chun Chen, Fung-Chang Sung

Counselor Education Faculty Publications and Presentations

Background

Depression is a common and mostly undertreated problem in patients with chronic diseases. However, population-based studies on the association between chronic obstructive pulmonary disease (COPD) and subsequent depression are limited in Asian populations. This study evaluated the incidence and risk factors of depression for patients with COPD in Taiwan.

Methods

Using the claims data from the National Health Insurance of Taiwan, we identified 38,010 COPD patients newly diagnosed in 2000–2004 and 38,010 subjects without COPD frequency, matched by sex, age and index date. The incidence rate and hazard ratio for depression were estimated by the end of 2008.

Harlot: A Revealing Look at the Arts of Persuasion

This is a multi-vocal, multi-institutional piece that examines ways women "make it" in rhetoric and composition. It is in the spirit of being more inclusive that we present our ideas about women's ways of making it in rhetoric and composition. This inclusiveness includes a written transcript of our audio narratives. Humbly, we present our work in this piece after four years of writing and revising in the work spaces we all know so well and offer several glimpses of the work women do as writing teachers. We honor all of the women who teach writing -- those who have made …

Grief Lives Online: An Empirical Study Of Kübler-Ross' Categories Of Bereavement On Myspace Profiles, Ilona Yurivna Malenkovich

Dissertations and Theses

With the widespread use of the Internet, grief has been extended in its representation. Specifically, social networking sites, like MySpace, have turned grief presentation from private expressions into public displays of mourning. This study utilizes the theoretical foundations of the grief presentation process of Kübler-Ross' (1969) five categories of bereavement (denial, anger, bargaining, depression and acceptance) to determine whether the grief presentation process is present in an online setting. In this study, the researcher conducted an empirical investigation of 4,931 comments, resulting in 22,263 bereavement themes outlined by Kübler-Ross, which were condensed into 2,288 time-point comparisons posted to 140 MySpace …
