Hvalfanger
Get PDFSubtitles are an element used within film to further meaning and artistic subtext, intentional or not, within film. Using foreign language and the associated cultural artefacts, one may explore the subtext of that language and culture on screen. The language of Norwegian, the language used in the film, shares much with English, however the cultures vary in numerous ways, such as whaling – something that is addressed in the film. By the way of delicate preparation and performance on-set, the visual and subtextual use of subtitles is explored within Hvalfanger. The film addresses differences in world view, generational values, and the struggle of communication through visual and textual cues. The meaning of the film as an art piece and as a product, refining the production process and its stages, and
the growth as an artist and filmmaker are reflection upon using the documents and documentation to exemplify the change throughout the experience
Investigation of MoS2 with Ambient Pressure X-ray Photoelectron Spectroscopy
Get PDFMolybdenum disulfide (MoS2) has potential applications as a low-cost catalyst for the hydrogen evolution reaction (HER). Defects on MoS2, such as edge sites and sulfur vacancies, are known to be the major active sites for HER. Controlling the formation of these defects allows for the enhancement in reactivity of MoS2 and other 2D materials. In this study, we have characterized the surface reactivity of bulk MoS2 samples using ambient pressure X-ray photoelectron spectroscopy (APXPS). Samples were exposed to 1 mbar of H2O vapor at temperatures ranging from 300-600 K. The APXPS Mo 3d, S 2p, and O 1s core levels for the as exfoliated surface showed no significant changes under all reaction temperatures due to the inert nature of the pristine MoS2 surface. To improve surface reactivity and activate the basal plane of MoS2 we have utilized Ar+ sputtering to form well controlled defect densities at the surface. The APXPS Mo 3d, S 2p, and O 1s core levels for the defective MoSx (x = 1.6, 1.2) surface showed the formation of MoO3 and MoOS at temperatures of 400 K and above. We have found that surface reactivity of MoS2 is strongly dependent on temperature and defect densities
The Economics of Electrifying Buildings in Corvallis: A Benefit-Cost Analysis on a Potential Corvallis Policy to Ban Natural Gas Infrastructure in New Residential Homes
Get PDFOver 76 cities throughout the United States have already adopted policies to limit the expansion of natural gas, mainly through updates to city codes that ban natural gas infrastructure in new construction. Rising concern over the environmental and public health impacts of methane - a greenhouse gas with a much higher global warming potential (GWP) than carbon dioxide and the primary component of natural gas - has motivated these policies. This analysis seeks to answer: would a policy that places a ban on natural gas infrastructure in new residential homes in Corvallis generate a net social benefit for the City of Corvallis? I find that an all-electric new home in Corvallis has lower 20-year net present energy bill costs, lower 20-year net present CO2e emissions costs, and lower upfront costs compared to a new mixed-fuel home in Corvallis. These findings are consistent with the findings of similar analyses in other cities and suggest that the City of Corvallis should consider adopting a natural gas infrastructure ban in new residential homes. If Corvallis does adopt a natural gas infrastructure ban, the city should also implement safeguards to protect low-income natural gas customers from bearing a greater burden of rising natural gas rates and consider complementary policies to ensure new affordable housing is built all-electric.Keywords: Benefit-cost analysis, natural gas, electricity, economics, Corvalli
SIMstat: Hardware Design Considerations for Implementing a Low-Cost, Portable Potentiostat
Get PDFElectroanalytical techniques allow scientists and engineers to characterize bulk solutions as well as interfaces. Potentiostats are commonly used by researchers in a variety of disciplines to analyze the chemistry which occurs at a working electrode surface. Advancements in microelectronics and the proliferation of open-source designs have allowed researchers to construct their own potentiostats which are both cheaper and more portable than their benchtop counterparts. High-end laboratory potentiostats cost thousands of dollars, which has motivated academics to design their own low-cost potentiostats suitable for unconventional applications. Many handheld potentiostats have been designed over the years which achieve current measurement accuracies near their benchtop counterparts. This article serves to summarize the state of low-cost potentiostat research and will analyze the engineering tradeoffs made in several frequently cited designs. Then, we will summarize the design and development thus far for a new low-cost potentiostat, named “SIMstat.” The research and development completed for the completion of this thesis can be used to accelerate both the design and implementation a new low-cost potentiostat for the Sensors and Integrated Microelectronics (SIMs) Lab at Oregon State. Additionally, this thesis will serve as a resource to educate electrical engineers about electrochemical principles for circuit design
Physics Students' Mindsets and Their Impact on Learning and Perceived Satisfaction
Get PDFCharacterizing a mindset landscape within the physics classroom is crucial to portray the variation and context of mindset in the classroom. This paper will be looking at students enrolled in Oregon State University’s PH20x series, which is a series of three algebra-based introductory physics courses. This project is an exploratory model which intends to obtain data on students’ fixed or growth mindsets through mixed methods. The approach will utilize a three-pronged method to get an in-depth, yet large scope of understanding of students’ mindsets. This will be achieved by conducting interviews on several students, supplemented with a follow-up email to explore whether having a fixed or growth mindset leads to greater outcomes or perceived satisfaction. Interviews were analyzed utilizing Angie Little’s Codebook [1]. For a broader understanding of the student population, a Likert scale will be distributed to all students within the class.
Themes of context and conditional dependency emerged during the analysis of the transcripts. Contextual dependency seems to affect both mindset and response, and applicability to the future was seen as the greatest influence in transcripts showing contextual dependency. For students showing a conditionally dependent mindset, performance is a large component in dictating a student’s response to challenge.Keywords: physics, mindset theory, motivation, fixed, growth, satisfaction, learning, implicit, entity, incrementa
Identifying Characteristics of Successful Fashion Bloggers and Their Influence on Consumer Purchase Decisions
Get PDFFashion bloggers have become a changing force of the retail industry over the past decade, redefining where consumers look for fashion inspiration, product reviews, and brand credibility. Despite the widespread popularity of fashion bloggers, there is little industry consensus as to what characteristics make a fashion blogger successful and to what extent they influence consumer purchase decisions. This study investigates the role of fashion bloggers, how they are perceived, and their effectiveness at influencing consumer purchase decisions. An online survey was distributed and a total of 76 individuals aged 18 and older participated in this study. The results indicated that the commonalities between fashion bloggers are that they serve as style and aesthetic inspiration. Online shopping is a common trait amongst the respondents but there is a clear gap in their buying choices and the products shared by fashion bloggers because only 57.53% of respondents have purchased an item a blogger recommended. The survey responses showed that the most common reasons an individual does not purchase a blogger’s recommendation is price or doesn’t fit with their needs/wants. We can hypothesize that fashion blogger’s serve as an inspiration figure rather than a personal seller to the majority of their audiences
Investigating Working Class Representatives and Policy Preferences
Get PDFWhile an abundance of research exists that looks at the impact that representatives’ backgrounds have on policy decisions, most of this research is focused on the areas of race and gender. As a result, there is a large gap in the literature that specifically looks at the impact that matters of class have on policy outcomes. In this study, I attempt to fill this gap by investigating the relationship between U.S Representatives from working class backgrounds and their support for working class policy. Due to the large impact that one’s background has on the formation of their political ideology, I expected representatives from the working class to be more likely to support working class policy than representatives from other backgrounds. To test this hypothesis, I used keyword searches to analyze press releases from the 114th congress as a means of measuring support for working class policy. I then analyzed the backgrounds of the representatives from the 114th congress to determine which of them are from the working class based on a separate list of criteria. Next, I plugged this data into statistical software and ran regression analysis to determine if there is a relationship between the variables. Although my findings failed to demonstrate any significant relationship between the proxy variables that were used to isolate representatives from the working class and the dependent variable, other variables did come up as being significant. In the conclusion section, I speculate as to what could be the reasons for this unexpected result.Key Words: Working Class, Voting behavior, Underrepresentation, Descriptive Representatio
How to use a plant identification key [1988]
No full textPlants can be identified by means of keys based on plant characteristics, frequently the flower. Keys enable the user to distinguish one species of plant from another. However, a single key to all flowering plants would be so cumbersome it would be impractical to use. Thus plant manuals ordinarily contain keys for identification of only those plants found in a given area along with detailed descriptions of the plants. Select a manual covering the particular region where a plant is found.Reprinted July 1988. Facts and recommendations in this publication may no longer be valid.

Gastrointestinal Parasitism and Mercury in Pacific Walrus
Get PDFThe Pacific Walrus population that lives within the Chukchi Sea near Alaska and the Russian territory Siberia have traditionally held a diet composed of molluscs and benthic invertebrates, with the main dietary choice being clams or other bivalves. Due to global warming, the availability of stable ice resting surfaces has decreased. Without these ice resting surfaces, it is possible that walrus resort to feeding on species within their diets that are higher in trophic level, resulting in an overall change in their nutrient and parasite intake. The objective of this research is to quantify and categorize the parasites in feces of the Pacific Walrus as well as to quantify and explore links between fecal mercury and parasitic numbers. Correlations between parasite richness and MeHg levels, parasite number and MeHg levels, parasite richness and THg levels, and parasite number and THg levels were all deemed statistically insignificant, likely in part due to low sample sizes. This thesis is a pilot study for further insight into the survival of the Pacific Walrus and with further data collection may provide a link between global warming and a change in walrus health.

A Discourse on the Gauge Integral
Get PDFThe gauge integral is a rather obscure object in mathematics. Like the Riemann integral, it is relatively simple to define, but unlike the Riemann integral, the gauge integral has the ability to integrate a very large class of functions. Here, we provide a development of the gauge integral at an undergraduate level, and are careful to include all relevant details when providing proofs of claims. We start by providing necessary background information, then move on to define the gauge integral and develop its properties, including statements and proofs of the major convergence theorems. We finish with a discussion on the space of gauge integrable functions and its relationship to the spaces of Riemann and Lebesgue integrable functions
