The Influence Of Shared Mobility And Transportation Policies On Vehicle Ownership, Edgar Bertini Ruas

PSU Transportation Seminars

With the emergence of several new providers of shared mobility services, such as Uber, Biketown and Car2go, there has been the promise of changes to the traditional way of owning and using a vehicle. One potential consequence of the new mobility services is the reduction in vehicle ownership. At the same time, cities are trying to anticipate these changes by reducing the amount of space dedicated to parking. This thesis aims to asses the extent to which new shared mobility and transportation policy strategies (especially parking requirements and transit pass availability) relate to vehicle ownership among residents of multifamily dwellings. …

Webinar: Segmenting The Market For Transportation Demand Management Campaigns, Philip L. Winters, Amy Lester

TREC Webinar Series

Social marketing seeks to develop and integrate marketing concepts with other approaches to influence behaviors that benefit individuals and communities for the greater social good. It 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 successfully used in Europe for its applicability to marketing efforts in the United States. Attitudinal and demographic data were collected from 1900 individuals in Florida, Oregon, and Virginia modeled after the European approach. Clustering analysis was applied to divide the sample into segments so that members of …

Age-Based Differences In The Usefulness Of Resources: A Multi-Study Investigation Of Work And Well-Being Outcomes, Lale Muazzez Yaldiz

Dissertations and Theses

The labor force is aging globally. It is projected that the number of older workers will increase in the workforce in the near future. At the same time, it is estimated that workplaces will grow more age-diverse, where younger and older workers will work side-by-side more often than they used to. These demographic shifts in the workforce necessitate a further understanding of the differences between the values, needs and motivation, and work outcomes of employees of different ages. To this end, few studies to date have investigated whether job-related resources are differentially useful for the work and non-work outcomes of …

The Role Of The Academic Analyst In Shared Governance, Rebecca Ann Mathern

Dissertations and Theses

This research explores the roles of academic professionals in higher education, specific to how they engage in decision-making processes. Academic professionals provide important functions in higher education work but there is little in the literature about these actors and their contributions to leadership and governance. A literature review triangulated role theory, organization theory, and the shared-governance field of study to bring together actors within higher education and compare their involvement based on the shared-governance model in operation at different institutions. The researcher introduced the hypothesis that when registrars are not involved in curriculum management, there may be negative effects on …

Investigating Time During Residential Program Until Transition For Adjudicated Youth: A Mixed Methods Study Using Event History Analysis With Follow-Up Interviews, Emily Carol Lott

Dissertations and Theses

Residential placement is considered the most severe sanction for adjudicated youth, yet there is little consensus on best practices and interventions in residential settings. Demographic trends in the juvenile justice system further exacerbate challenges in studying residential placements. Disparities among minority youth, diverging state definitions of juvenile sex offenses, discrepancies in recidivism measures, and variations in local and state juvenile courts have contributed to a convoluted system that has struggled to identify the meaning of "success" in residential settings.

Building on theories of engagement in residential care and program theory of change, this mixed methods study explores how various components …

Scenarios For Adoption Of Autonomous Vehicle Technologies In Freight, Sabya Mishra

PSU Transportation Seminars

Innovation adoption research has largely ignored organizational adoption, and little work has been done to understand or predict the adoption of innovations by freight organizations. Among the existing innovation adoption theoretical and methodological approaches this seminar will explore which are most appropriate methods for freight organizational adoption. The seminar will present a disaggregate market penetration model for freight transportation organizations adopting connected autonomous vehicle (CAV) technology and demonstrate an application using a case study area in Memphis, TN. The seminar will highlight ongoing and future organizational adoption research for CAVs, and other innovations.

Portland’S Transportation Wallet: How Pricing Parking Can Create New Mobility Options, Sarah Goforth

PSU Transportation Seminars

The Transportation Wallet is one of Portland’s newest parking and transportation demand management (TDM) strategies, designed to reduce parking demand while simultaneously offering new mobility options by bundling transit and bike share passes into one consumer product. Two of Portland’s managed parking districts have elected to add a surcharge to the cost of on-street parking permits, a portion of which is used to subsidize the cost of the Transportation Wallet. Residents and employees in the parking districts are eligible to purchase the Transportation Wallet at a fraction of the retail cost. As an added incentive to increase parking supply, people …

Studying The Effects Of Motivated Reasoning On Appraisals Of Message Strength, Aric Christopher Powell

Dissertations and Theses

This study was designed to investigate decision-making as it relates to message appraisal, and determine what effect, if any, identification with the message source has on those appraisals. For the purpose of study, message appraisal was operationalized as message strength ratings. Furthermore, the study investigated how the political ideology of message receivers and the perceived partisanship of message senders might influence identification, and message appraisal by extension. The study used the theory of motivated reasoning to explain the role of identification in the process of message appraisal. The results indicate that there is a relationship between identification and message strength …

Judgments Of Lethal Risk: A Comparison Of Visual And Narrative Stimuli, Derek Anthony Bonniksen

Dissertations and Theses

The nature of how we make judgments has received a great deal of attention in the last few decades. Risk communication research has indicated that risk-related messages can elicit affective responses in audiences, which can then have a significant impact on how such audiences judge risk in general. Using a 2 x 2 between-subjects factorial design, this study found that, contrary to Johnson and Tversky's (1983) findings, presenting narratives about lethal risk does not influence readers' judgments about the frequency that risks occur, nor do such narratives influence participant worry levels about the lethal risks, more generally. Additionally, the inclusion …

Is Public Transit's 'Green' Reputation Deserved?, Justin Beaudoin

PSU Transportation Seminars

While public transit has a reputation as a potential means to ameliorate the adverse environmental effects of automobile travel, there have been very few empirical studies of the marginal effect of transit supply on air quality. We explore whether any of the substantial improvement in air quality observed in the U.S. from 1991 to 2011 can be attributed to increased public transit supply by developing an equilibrium model of transit and automobile travel volumes as a function of the level of transit supplied. We then empirically analyze the effects of the level of transit supply on observed ambient pollution levels …

Health Behavior Among Men Occupying Multiple Family Roles And The Moderating Effects Of Perceived Partner Relationship Quality, Nicole Depasquale, Courtney A. Polenick, Jesse Hinde, Jeremy Bray, Steven H. Zarit, Phyllis Moen, Leslie B. Hammer, David M. Almeida

Psychology Faculty Publications and Presentations

Men in the U.S. are increasingly involved in their children’s lives and currently represent 40% of informal caregivers to dependent relatives or friends aged 18 years or older. Yet, much more is known about the health effects of varying family role occupancies for women relative to men. The present research sought to fill this empirical gap by first comparing the health behavior (sleep duration, cigarette smoking, alcohol consumption, exercise, fast food consumption) of men who only occupy partner roles and partnered men who also fill father, informal caregiver, or both father and informal caregiver (i.e., sandwiched) roles. The moderating effects …

Development And Testing Of An Assessment Of Youth/Young Adult Voice In Agency-Level Advising And Decision Making, Janet S. Walker, Brie Masselli, Jennifer E. Blakeslee, Caitlin Baird, Kristin Thorp

School of Social Work Faculty Publications and Presentations

There is a range of stakeholder benefits when youth- and young adult-serving agencies include service recipient “voice” in advising and decision making regarding agency policies and programming. Yet many agency stakeholders lack awareness of strategic best practices to ensure the consistent and meaningful participation of young people in decision-making processes, and few tools exist to evaluate agency efforts. This paper describes the development and validation of the Youth/Young Adult Voice at the Agency Level (Y-VAL), an assessment of the extent to which agencies have implemented best practices for supporting meaningful participation. The Y-VAL is intended for research purposes, as well …

Ptsd Symptomology And Motivated Alcohol Use Among Military Service Members: Testing A Conditional Indirect Effect Model Of Social Support, Cameron T. Mccabe, Cynthia Mohr, Leslie B. Hammer, Kathleen F. Carlson

Psychology Faculty Publications and Presentations

Background: Posttraumatic stress disorder (PTSD) and problematic alcohol use commonly co-occur among military service members. It remains critical to understand why these patterns emerge, and under what conditions. Objectives: This study examined whether PTSD symptoms (PTSS) and alcohol involvement (quantity and frequency of use, heavy episodic drinking, and alcohol problems) are indirectly related through four distinct drinking motivations. A secondary aim was to identify factors, specifically forms of social support, which buffer these associations. Methods: Using baseline data from a randomized-controlled trial of health and well-being among civilian-employed separated service members and reservists, the present study examined these issues using …

"A Well Spent Day Brings Happy Sleep": A Dyadic Study Of Capitalization Support In Military-Connected Couples, Sarah N. Arpin, Alicia Starkey, Cynthia Mohr, Anne Marie D. Greenhalgh, Leslie B. Hammer

Psychology Faculty Publications and Presentations

Among couples, sleep is theorized to be a dyadic process, within which relationship quality exerts a large influence (Troxel, Robles, Hall, & Buysse, 2007). In turn, research has shown that capitalization, or positive-event disclosure, influences relationship quality. The benefits of capitalization, however, are contingent on the receipt of a supportive response, here referred to as capitalization support (Reis & Gable, 2003). Accordingly, the current study examined daily capitalization support, loneliness, and intimacy as predictors of sleep (i.e., quality, duration, difficulty falling asleep). Post-9/11 military veterans and their spouses (N = 159) completed a 32-day internet-based survey assessing daily relationship experiences …

Webinar: Addressing Bicycle-Vehicle Conflicts With Alternate Signal Control Strategies, Sirisha Kothuri

TREC Webinar Series

There is nationwide interest in supporting sustainable and active transportation modes such as bicycling and walking due to the many benefits associated with them, including reduced congestion, lower emissions and improved health. Although the number of bicyclists is increasing, safety remains a top concern. In urban areas, a common crash type involving bicycles at intersections is the “right hook” where a right-turning vehicle collides with a through bicyclist. While geometric treatments and pavement markings have been studied, there is a lack of research on signal timing treatments to address right-hook bicycle-vehicle conflicts.

Transportation Behavior Change...Now With Science!, Jessica Roberts

PSU Transportation Seminars

How can we encourage people to make use of the transportation systems in place - to improve transit ridership and, in turn, to improve the health and happiness of our societies?

New findings in behavioral science could unlock new, more effective ways to change transportation behavior...but only if we have a way to find and use that evidence. TransLink (Vancouver BC) undertook a groundbreaking research effort to use cognitive biases to explain why people drive today, and and to identify possible "nudge" strategies to shift those trips to transit and active modes. The resulting report includes brand-new ideas that area …

Pedestrian Pedagogy Of Place: Nurturing An Ecological Consciousness Through Slow Explorations Of The Public Realm, Kevin M. Pozzi

Leadership for Sustainability Education Comprehensive Papers

As increasing institutional paralysis and polarization demonstrate, citizens are not engaged or motivated by ecological challenges because they struggle to identify with our catastrophic relationship to nature in this urban, anthropocentric, and climactically-fraught modern era. Rather than focus solely on natural areas as a pathway to ecological consciousness and action, educators can inspire citizens through a “Pedestrian Pedagogy of Place” that brings wonder and enchantment into our urban public realm. Using the principles of sustainability education and place-based education as a framework, this pedagogy recognizes the sidewalk and pedestrian experience as a shared classroom through sensory, awareness-based learning modalities.

Creating An Organizational Self-Assessment Tool To Evaluate Progress Toward System Change, Karen Cellarius

Regional Research Institute for Human Services

Studies have shown that programs with higher fidelity to certain evidence-based practices have better treatment outcomes than programs with lower fidelity. The clinical assessment method outlined in this poster can be adapted to create a tool for measuring how closely an organization is implementing system change and maintaining it over time, while also educating program staff on what optimal implementation looks like.

Investigating Predictors Of True And False Guilty Pleas, Kelsey S. Henderson, Lora M. Levett

Criminology and Criminal Justice Faculty Publications and Presentations

An estimated 90% to 95% of convictions are obtained via guilty pleas, and roughly 11% of individuals exonerated with the help of the Innocence Project falsely pleaded guilty (innocenceproject.org). Despite the prevalence of guilty pleas (and the existence of false guilty pleas), relatively little scholarship has examined what influences a defendant to plead guilty (Redlich, 2010). In this study, we investigated factors that affected whether guilty and innocent students who were accused of cheating pleaded guilty or took their case before the Student Conduct Committee in a hearing (analogous to a trial). Using social psychological literature on social influence (Cialdini …

Regional Research Institute for Human Services

Community-based participatory research (CBPR) answers the call for more patient-centered, community-driven research approaches to address growing health disparities. CBPR is a collaborative research approach that equitably involves community members, researchers, and other stakeholders in the research process and recognizes the unique strengths that each bring. The aim of CBPR is to combine knowledge and action to create positive and lasting social change. With its origins in psychology, sociology, and critical pedagogy, CBPR has become a common research approach in the fields of public health, medicine, and nursing. Although it is well aligned with psychology’s ethical principles and research aims, it …

Human Settlement And Mid-Late Holocene Coastal Environmental Change At Cape Krusenstern, Northwest Alaska, Shelby Anderson, James Jordon, Adam Freeburg

Anthropology Faculty Publications and Presentations

Archaeologists hypothesize that mid-late Holocene environmental variability played a role in several significant western Arctic cultural developments including population fluctuations, the evolution of Arctic maritime adaptations, and Arctic-wide migrations. Further evaluation of these hypotheses requires higher resolution archaeological and paleoecological datasets than are currently available. In response, we undertook an interdisciplinary study at Cape Krusenstern, a large coastal site complex in northwest Alaska, which was occupied over the last ca. 5000–6000 years. Our goals were to refine local cultural and paleoenvironmental chronologies and to explore the question of how local environmental change may have influenced local settlement history. The resulting …
