Revealing Structural Organization With Liquid Crystal-Based Spectral Imaging Polarimetry, James Campbell Gladish

Dissertations and Theses

Structural organization refers to the particular ordering of scatterers. Probing structural organization by imaging polarized spectral scatter provides insight into the composition of a medium, and can aid in remote sensing, the identification of tissue pathologies, and material characterization and differentiation. The vector nature of polarized light enables it to interact with optical anisotropies within a medium, while the spectral aspect of polarization is sensitive to small-scale structure. However, many polarization studies have limitations, as they provide qualitative image analysis, incomplete anisotropy information, or both. The ability to image the effects of anisotropy and small-scale structure at multiple wavelengths is …

Intrapersonal And Interpersonal Consequences Of Loneliness: Health Behavior, Social Interactions, Self-Disclosure, And Perceived Responsiveness, Sarah Noel Arpin

Dissertations and Theses

As a social species, human beings are driven by an innate desire to belong and are thus motivated to develop and maintain meaningful social relationships. As such, perceiving a lack of belongingness strongly impacts psychological and physiological health and well-being. A common form of perceived relationship deficits is loneliness, a negative-affective experience detrimental to health and well-being over time. Through a series of three manuscripts, this dissertation applies the full-cycle model of social psychological research to explore various affective, behavioral, and cognitive consequences of loneliness. Whereas existing models of loneliness focus on long-lasting or chronic forms of loneliness, these studies …

Staying On Script: Sexual Scripts And Sex Education, Elizabeth Carol Hauck

Dissertations and Theses

Existing research suggests that men and women develop differing sexual scripts that influence their behavior, interactions and emotions regarding sex. The objective of this project is to examine the experiences of men and women with formal sex education programs, especially in regards to information about: anatomy and biology, sexual responsibility and risk taking, sexual desire, virginity and abstinence, as well as to explore sources of sex education outside of school. Several studies suggest masculine sexual scripts dictate that men generally construct a more body-focused approach to sex, with an emphasis on competition, aggression and achievement. Conversely, emphasized feminine sexual scripts …

Novel Methods For Learning And Adaptation In Chemical Reaction Networks, Peter Banda

Dissertations and Theses

State-of-the-art biochemical systems for medical applications and chemical computing are application-specific and cannot be re-programmed or trained once fabricated. The implementation of adaptive biochemical systems that would offer flexibility through programmability and autonomous adaptation faces major challenges because of the large number of required chemical species as well as the timing-sensitive feedback loops required for learning. Currently, biochemistry lacks a systems vision on how the user-level programming interface and abstraction with a subsequent translation to chemistry should look like. By developing adaptation in chemistry, we could replace multiple hard-wired systems with a single programmable template that can be (re)trained to …

The Floating Men: Portland And The Hobo Menace, 1890-1915, Marin Elizabeth Aurand

Dissertations and Theses

At the beginning of the twentieth century, transient laborers in Portland, Oregon faced marginalization and exploitation at the hands of the classes that relied on them for their own prosperity. Portland at this time was poised to flourish as a major population and industrial center of the American West. The industries that fueled the city's growth were dependent on cheap and mobile manual labor made available by the expansion of the nation's railroads. As the city prospered and grew, the elite of the city created and promoted an image of Portland as an Eden of material abundance where industriousness and …

Democratizing The City Through The Colonization Of Public Space: A Case Study Of Portland Food Not Bombs, Trent Adam Saari

Dissertations and Theses

The implementation of neoliberal economic and political policies is often touted as a way to increase overall individual well-being and freedom. While these policies may benefit those already wielding economic security and political power, marginalized populations often bear the negative cost associated with such policies. As deregulation and privatization increases, social safety nets and social spending are dramatically reduced. At the local level, liberalization has resulted in increased surveillance and regulation of public space. Organized resistance to global corporatization and increased economic and political marginalization has occurred across the globe. Resisting neoliberalism is complex as the adaptability of the state …

Curating Massive Media, Dave Colangelo

School of Film Faculty Publications and Presentations

The European Union’s media art initiative Connecting Cities and New York-based Streaming Museum are two recent examples of curatorial models that operate through large, networked, digital displays. This growing exhibition category combines expressive media architecture and telecommunication elements to engage ‘trans-local’ sites and diverse publics in complex media spaces. By investigating the confluence of exhibition making, public art and urban experience, this article explores the relationship between spectacle and criticality with respect to shifting notions of space, identity and ‘the common’.

Note: At the time of writing, Dave Colangelo was affiliated with Ryerson University.

Coping With Information Technology: Mixed Emotions, Vacillation, And Nonconforming Use Patterns, Mari-Klara Stein, Sue Newell, Erica L. Wagner, Robert D. Galliers

Business Faculty Publications and Presentations

Achieving the promised business benefits of an IT system is intimately tied to the continued incorporation of the system into the work practices it is intended to support. While much is known about different social, cognitive, and technical factors that influence initial adoption and use, less is known about the role of emotional factors in users' behaviors. Through an in-depth field study conducted in two North American universities, we examine the role of emotions in how specific IT use patterns emerge. We find that there are five different characteristics of an IT stimulus event (cues) that, when interacting in a …

Selfish Mitochondrial Dna Proliferates And Diversifies In Small, But Not Large, Experimental Populations Of Caenorhabditis Briggsae, Wendy S. Phillips, Anna Luella Coleman-Hulbert, Emily S. Weiss, Dana K. Howe, Sita Ping, Riana I. Wernick, Suzanne Estes, Dee R. Denver

Biology Faculty Publications and Presentations

Evolutionary interactions across levels of biological organization contribute to a variety of fundamental processes including genome evolution, reproductive mode transitions, species diversification, and extinction. Evolutionary theory predicts that so-called “selfish” genetic elements will proliferate when the host effective population size (N_e) is small, but direct tests of this prediction remain few. We analyzed the evolutionary dynamics of deletion-containing mitochondrial DNA (ΔmtDNA) molecules, previously characterized as selfish elements, in six different natural strains of the nematode Caenorhabditis briggsae allowed to undergo experimental evolution in a range of population sizes (N = 1, 10, 100, and 1,000) for a maximum …

Turkish Think Tanks, The Akp’S Policy Network From Neo-Gramscian And Neo-Ottoman Angles, Kubilay Arin

Center for Turkish Studies Occasional Paper Series

This paper will show how the AKP’s utilization of political Islam together with framing of neo-Ottomanism as a prerequisite for its opening to the Muslim world as the former Ottoman lands in the Balkans, the Caucasus and the Arab Peninsula exacerbate tensions with it western partners. At the domestic politics level, the Islamic-conservative Justice and Development Party is generally accepted more libertarian than its predecessor the Islamist Welfare party with a platform based on strong national security, free markets and social and fiscal conservatism. The Islamists and the libertarians are often competing for influence in the AKP. The study counters …

Building Social Sustainability From The Ground Up: The Contested Social Dimension Of Sustainability In Neighborhood-Scale Urban Regeneration In Portland, Copenhagen, And Nagoya, Jacklyn Nicole Kohon

Dissertations and Theses

In response to growing social inequality, environmental crises, and economic instability, sustainability discourse has become the dominant "master signifier" for many fields, particularly the field of urban planning. However, in practice many sustainability methods overemphasize technological and economic growth-oriented solutions while underemphasizing the social dimension. The social dimension of sustainability remains a "concept in chaos" drawing little agreement on definitions, domains, and indicators for addressing the social challenges of urban life. In contrast, while the field of public health, with its emphasis on social justice principles, has made significant strides in framing and developing interventions to target the social determinants …

Discursive Security: F.B.I. Stings And The Nature Of Peace, Adam Testerman

Dissertations and Theses

The current study utilizes Critical Discourse Analysis and Thematic Analysis to study newspaper coverage of F.B.I. sting operations in The New York Times, Washington Post, and USA Today. F.B.I. sting operations are a modern counter-terrorism policy designed to preempt acts of terrorism. This study develops a theoretical approach to understanding F.B.I. sting operations by reviewing the critique of security. The critique of security suggests that nations construct threats in order to produce and maintain ideological and practical hegemony. Thematic categories of the newspaper discourse are formulated and analyzed in the context of security. The study employs aspects of grounded theory …

This dissertation includes three studies that expand our knowledge of the implications of workplace aggression in the work and nonwork domains. Further, this research illuminates the processes through which this relationship occurs by utilizing various sources of data from employees in a variety of contexts including universities, long term health care, and the USDA Forest Service. In Study 1, which was published in the Journal of Occupational Health Psychology, multi-source data are utilized to identify the indirect effects of …

Got Hair That Flows In The Wind: The Complexity Of Hair And Identity Among African American Female Adolescents In Foster Care, Lakindra Michelle Mitchell Dove

Dissertations and Theses

African American children are disproportionately over-represented in the child welfare system. Many of these children linger in the system and experience disconnection from their biological families, communities, cultural beliefs, values, and practices. Familial socialization and cultural exposure are essential to developing a positive ethnic identity and self-concept. For African American female adolescents, hair and hair care are critical areas for such socialization and support. This qualitative study explored the hair and hair care perceptions and experiences of African American female adolescents in foster care. The goal was to examine hair and hair's connection to, and influence on, sense of self …

Building Resources At Home And At Work: Day-Level Relationships Between Job Crafting, Recovery Experiences, And Work Engagement, Allison Marie Ellis

Dissertations and Theses

Work engagement is an increasingly popular construct in organizational and occupational health psychology. However, despite substantial advances in our understanding of work engagement at the between-person level, scholars have argued for increased investigation into what drives engagement on a daily level for individual employees. In the current study, a within-person, day-level design was employed to examine the relationships between nonwork mastery experiences, job crafting behaviors, and daily work engagement. Drawing on Conservation of Resources (Hobfoll, 1989) theory, nonwork mastery experiences and job crafting were operationalized as employee-driven, resource-building strategies that assist employees in generating important psychological and job resources that …

Sound Effects: Age, Gender, And Sound Symbolism In American English, Timothy Allen Krause

Dissertations and Theses

This mixed-method study investigated the correlation of sound symbolic associations with age and gender by analyzing data from a national survey of 292 American English speakers. Subjects used 10 semantic differential scales to rate six artificial brand names that targeted five phonemes. Subjects also described the potential products they imagined these artificial brand names to represent. Quantitative analysis alone provided insufficient evidence to conclude that age or gender affect sound symbolism in American English. While 26 out of 60 scales showed a monotonic shift among the means of the three age groups, only three were statistically significant. The evidence of …

Communicating With Technology In Our Workplace, Amelia Hill

Student Research Symposium

When modern technology took off in the 1990’s it surpassed all previous forms. It’s amazing how technology can be, it is used to keep families and friends in contact, and it has advanced medical research, and enables the growth of businesses. While technology can enhance communications within an organization, it can also cause misinformation, distraction, and there is always ‘technology difficulties’. These present a few organizational risks and challenges of human interaction in a work place that will be described in this essay. It is important to look into these problems so the professional world is aware of them and …

Freedom From Equality: Democratic Education And The Failure Of The Nclb, Andrew X. Fleming

Student Research Symposium

Deeply rooted societal concerns about what role democratic ideals should play within systems of education, and how much sway the federal government should hold over educational institutions, have been at the forefront of American educational policy for decades. These questions have more recently been brought into the limelight once again within the context of the implementation of charter schools and the controversial No Child Left Behind act, and its subsequent failure. The expressed goal of this paper is to provide an examination of what philosophies and ideals of so-called "democratic education" are have played major roles in developing the discourse …

Retracing Foucault: Neoliberalism And The Occupy Movement, Jaycob Izso

Student Research Symposium

The Occupy movement presented itself as a reaction to a socio-economic relation; to some it decried the unconstrained expanses and injustices of capitalism, to others it was a resistance to the gross economic disparity perpetuated by a subset of the social strata that lacked governmental accountability. Branded by some as neo-Marxist, by others as merely lazy or lacking any concrete objectives – the Occupy movement met with mixed results. By providing an archaeology of neoliberal governmentality by-way of Michel Foucault; I believe we can not only elucidate the underpinning and political origins of the movement, but also seek to clarify …

The Ability Of Narrative Communication To Address Health-Related Social Norms, Meghan B. Moran, Sheila T. Murphy, Lauren B. Frank, Lourdes Baezconde-Garbanati

Communication Faculty Publications and Presentations

Social norms are an important predictor of health behavior and have been targeted by a variety of health communication campaigns. However, these campaigns often encounter challenges related to the socially specific context in which norms exist: specifically, the extent to which the target population identifies with the specific reference group depicted and the extent to which the target population believes the campaign’s message. We argue that because of its capacity to effect identification among viewers, narrative communication is particularly appropriate for impacting social norms and, consequently, behavioral intention. This manuscript presents the results of a randomized trial testing the effectiveness …

Measuring The Effect Of Vegetated Roofs On The Performance Of Photovoltaic Panels In Combined Systems, Hamid Hawi Kadham Ogaili

Dissertations and Theses

Recent studies suggest that integration of photovoltaic panels with green roofs may improve the performance of both. While vegetation may provide a benefit by reducing the net radiation load on the underside of the photovoltaic (PV) panels, it may also affect convective cooling of panels, and consequently, panel efficiency. Both effects likely diminish with the height of the PV panel above the roof, although placing PV panels too close to the vegetation increases the risk of the plants growing over the edges of, and shading the PV panel. There is a gap in the literature with respect to evaluating these …

Modeling The Optical Response To A Near-Field Probe Tip From A Generalized Multilayer Thin Film, A.J. Lawrence

Dissertations and Theses

The contrast mechanism in Kerr imaging is the apparent angle through which the plane of polarization is rotated upon reflection from a magnetic surface. This can be calculated for a well characterized surface given the polarization state of the incident light. As in traditional optical microscopy, the spatial resolution is limited by diffraction to roughly half the wavelength of the illumination light.

The diffraction limit can be circumvented through the use of near-field scanning optical microscopy, in which the illumination source is an evanescent field at the tip of a tapered optical fiber. A novel probe design for near-field optical …
