Defining Ccl20’S Role In Carcinogenesis, Melanie Schafer

University Honors Theses

It has become widely accepted that chronic inflammation is correlated with cancer. An important aspect in this relationship is the microenvironment established by inflammation and characterized by the production of small molecules known as cytokines and chemokines. One such chemokine, CCLZO, is a Th17 specific chemokine essential for Th17 activation. Although the contribution of Th1 and Th2 in carcinogenesis have been well established, Th17's role in cancer development has yet to be identified. In this study, we provide first experimental evidence regarding the functional role of CCL20 in turmorigenesis that can shed light onto Th17's function in cancer. We generated …

In Vivo Quantification Of Reactive Oxygen Species Demonstrates High Levels Of Oxidative Stress In Base Excision Repair-Deficient Caenorhabditis Elegans: Implications For Associative Metabolic Phenotypes, Travis Lee Hase

University Honors Theses

In this present study, I use C. elegans as a model organism to better characterize the phenotypic response to deficiencies in base excision repair (BER). This will help to elucidate how DNA damage, increased mutagenesis, and exposure to reactive oxygen species (ROS) is related to Metabolic Syndrome. Additionally, this work will establish a starting point for investigation that can further characterize phenotypic responses such as mitochondrial physiology and morphology through measurements of mitochondrial membrane potential and mitochondrial circularity. The overall goal of this research is to better understand the nature of mitochondrial dysfunction with respect to the inactivation of DNA …

Lay Versus Medical Analysis: A Conflict Centered On The Disciplinary And Professional Identity Of Psychoanalysis, Sam Yoder

University Honors Theses

The psychoanalytic conflict surrounding lay and medical analysis was a prominent conflict within both the European and American psychoanalytic communities. This thesis is an analysis of that conflict from the time period of 1900-1940. I argue that this conflict is an expression of two conflicting ideas for the disciplinary identity of psychoanalysis. Lay analysts believed that psychoanalysis should be a distinct discipline and be used in a multidisciplinary context. Medical analysts believed that through aligning psychoanalysis with medicine it would obtain professional legitimacy. This thesis also covers concepts of professionalization in disciplines.

Hyphens For Disambiguating Phrases: Effectiveness For Young And Older Adults, Inge Anema, Loraine Obler

Publications and Research

The purpose of this study was to investigate whether hyphens that disambiguate phrasing in ambiguous sentences influence reading rate and reading comprehension for younger and older adults. Moreover, as working memory (WM) has been implicated in age-related changes in sentence comprehension for both auditory and written materials, we asked if it contributed to comprehension of our sentences with hyphenated and non-hyphenated ambiguous noun phrases (NPs), predicting that the hyphens would reduce WM load. Twenty younger (M = 24 years) and 20 older (M = 73 years) adults read sentences with either ambiguous or non-ambiguous NPs that were either hyphenated or …

History, Interactive Technology And Pedagogy: Past Successes And Future Directions, Stephen Brier

Publications and Research

Based on a keynote presentation at the 2012 Canadian Historical Association conference, this paper surveys the state of digital technology and its impact on academic publication and teaching in the contemporary university. Focusing on the dramatic rise of the Digital Humanities in the last few years, the paper examines alternative forms of peer review, academic scholarship and publication, and classroom teaching as they have been reshaped by the adoption of a variety of digital technologies and formats, including open-access, online peer reviewing, use of data- bases and visualization techniques in humanities work, online journal publication, and the use of blogs …

Digital Video: Engaging Students In Critical Media Literacy And Community Activism, Jessie Daniels

Publications and Research

This article presents a strategy for teaching health communication that fosters critical media literacy through the strategic combination of digital video, documentary film, video worksheets, and peer-reviewed journal articles. Given the media-saturated environment in which notions of health are shaped, critical media literacy skills are crucial to students in health-related fields. Cases of key concepts illustrated through documentary films and the peer-reviewed literature are presented. The article then explores how one class took the lead in designing a community event that critically engaged both a YouTube video and a documentary film about police brutality as a public health issue.

Electric Lamp: Virtual Loop-Mediated Isothermal Amplification, Nelson R. Salinas, Damon P. Little

Publications and Research

We present eLAMP, a PERL script, with Tk graphical interface, that electronically simulates Loop-mediated AMPlification (LAMP) allowing users to efficiently test putative LAMP primers on a set of target sequences. eLAMP can match primers to templates using either exact (via builtin PERL regular expressions) or approximate matching (via the tre-agrep library). Performance was tested on 40 whole genome sequences of Staphylococcus. eLAMP correctly predicted that the two tested primer sets would amplify from S. aureus genomes and not amplify from other Staphylococcus species. Open source (GNU Public License) PERL scripts are available for download from the New York Botanical Garden’s …

Variability In The Mass Flux Of The Ross Sea Ice Streams, Antarctica, Over The Last Millennium, Ginny Catania, Christina L. Hulbe, Howard Conway, Ted A. Scambos, C. F. Raymond

Geology Faculty Publications and Presentations

We synthesize previously published remote-sensing observations, radar data and model output to obtain a ~1000 year ice flow history for the Siple Coast ice-stream system in West Antarctica to investigate the timing and magnitude of changes in mass flux. The synthesized history shows significant short-term variability in ice-stream shear margin and grounding line position due to internal variability of the coupled system. The chronology highlights the interplay between adjacent ice streams, which implies that the behavior of any individual ice stream should not be examined in isolation. Furthermore, individual events cannot be fully interpreted without an understanding of the broad-scale, …

A Study On Factors Affecting U.S. Bilateral Trade With Her Major Trading Partners, Won Joo Cho

Agribusiness and Applied Economics

The objective of this study is to analyze factors affecting U.S. bilateral trade with her major trading partners, including exchange rate, GDP, economic structure, market openness, and free trade agreements. Six commodity groups included in this study are agriculture, low technology, mid-low technology, mid-high technology, high technology, and overall trade. This research employs Bayesian econometric procedure to solve cross-sectional heterogeneity problem in estimating the bilateral trade model with the U.S. major trading partners for six commodity groups. Estimation results show that capital-labor ratio is more influential in U.S. bilateral trade with her major trading partners than exchange rate. In addition, …

The Relationship Between Water Pollution And Economic Growth Using The Environmental Kuznets Curve: A Case Study In South Korea, Jaesung Choi

Agribusiness and Applied Economics

This thesis reviews relationships between economic growth and water pollution in South Korea using the Environmental Kuznets Curve (EKC). Both national perspective (pooled data) and regional perspective (each river) are used to reveal the EKC theory. Given that the small sample covers four rivers and the period of 1985-2009, Fixed-effects model with a robust standard error is chosen for removing econometric problems. Empirical results demonstrate that the EKC theory explains water quality change in South Korea, depending on the types of water pollutants and their generated regional characteristics. The Han River does not show inverted-U shapes for BOD (Biochemical Oxygen …

Effects Of Winter Weather Risk On The Profitability Of Beef Feedlots In North Dakota, Billiejo Mae Armbrust Shae

Agribusiness and Applied Economics

This study examines the effects of management decisions, animal performance, weather risk, and economic variables on the profitability of the beef feedlot in North Dakota using data from the Dakota Feeder Calf Show and feed trials at North Dakota State University's Carrington Research and Extension Center. The effects of these variables were studied using an ordinary least squares analysis. Results demonstrated that severe cold stress reduced the profits of the feedlot in North Dakota. Results suggest that steers placed during the fall in North Dakota with placement weights > 600 pounds are more profitable to feed than lighter weight steers.

Myths And Measures: The Cultural Performance Of Portland’S Strip Club Identity, Wayne Coffey

Geography Masters Research Papers

Identities of place develop through a multitude of perceptions. Place myths guide much of this perception. Portland, Oregon’s identity has evolved in particular around a much quoted but unchallenged statistic regarding the volume of nude dancing venues. This paper focuses on the literature specific to both nude dance venues and place identity; Portland’s legal history that contributed to this phenomenon; and some of the cultural and spatial variables pertinent to this issue. Two initiatives, aimed at restructuring the state constitution specifically to deal with nude dance venues and other adult entertainment, are analyzed.

The Implications Of Migration Theory For Distributive Justice, Alexander Sager

Philosophy Faculty Publications and Presentations

This paper explores the implications of empirical theories of migration for normative accounts of migration and distributive justice. It examines neo-classical economics, world-systems theory, dual labor market theory, and feminist approaches to migration and contends that neo-classical economic theory in isolation provides an inadequate understanding of migration. Other theories provide a fuller account of how national and global economic, political, and social institutions cause and shape migration flows by actively affecting people's opportunity sets in source countries and by admitting people according to social categories such as class and gender. These empirical theories reveal the causal impact of institutions regulating …

Dynamic Ccd Pixel Depletion Edge Model And The Effects On Dark Current Production, Justin Charles Dunlap, Morley M. Blouke, Erik Bodegom, Ralf Widenhorn

Physics Faculty Publications and Presentations

The depletion edge in Charge-Coupled Devices (CCD) pixels is dependent upon the amount of signal charge located within the depletion region. A model is presented that describes the movement of the depletion edge with increasing signal charge. This dynamic depletion edge is shown to have an effect on the amount of dark current produced by some pixels. Modeling the dark current behavior of pixels both with and without impurities over an entire imager demonstrates that this moving depletion edge has a significant effect on a subset of the pixels. Dark current collected by these pixels is shown to behave nonlinearly …

Encounters With Witchcraft, Norman Miller

Dartmouth Scholarship

My first experience with witchcraft in Africa occurred in March 1960 in Mombasa, Kenya, just as I stepped off the gangway of the MS Inchanga following a voyage from India. Next to the ship in a dockside kiosk I saw a newspaper with the headline, “European Geologist Attacked in Gogoland: Witchcraft Suspected.” It was the story of a 22-year-old British geologist, William Hanning, who had been prospecting for minerals in a remote part of nearby Tanzania when by mistake he dug into a burial ground. He was believed to be a witch, disguised as a European, out to steal body …

Never Back Down, Ernest Hebert

Dartmouth Scholarship

I built Never Back Down along two tracks. First, it's my imagined life if I had never gone to college. The second track is based on Evangeline: A Tale of Acadie by Henry Wadsworth Longfellow. I wanted to write a story that resonated with my roots in French Canada.

A Reverberation Lag For The High-Ionization Component Of The Broad-Line Region In The Narrow-Line Seyfert 1 Mrk 335, C. J. Grier, B. M. Peterson, R. W. Pogge, K. D. Denney, M. C. Bentz, Paul Martini, S. G. Sergeev, S. Kaspi, Y. Zu, C. S. Kochanek, B. J. Shappee, C. Araya Salvo, T G. Beatty, J. C. Bird, D. J. Bord, G. A. Borman, X. Che, C. Chen

Dartmouth Scholarship

We present the first results from a detailed analysis of photometric and spectrophotometric data on the narrow-line Seyfert 1 (NLS1) galaxy Mrk 335, collected over a 120 day span in the fall of 2010. From these data we measure the lag in the He ii λ 4686 broad emission line relative to the optical continuum to be 2.7 °æ 0.6 days and the lag in the Hβλ 4861 broad emission line to be 13.9 °æ 0.9 days. Combined with the line width, the He ii lag yields a black hole mass MBH = (2. 6 °æ 0. 8) °ø 107M …

Artification And The Aesthetic Regime Of Art, Aleš Erjavec

Contemporary Aesthetics (Journal Archive)

The author discusses “artification” and attempts to ascertain whether some common features can be found between artification and Jacques Rancière’s aesthetics, especially his notion of the “aesthetic regime of art.” The author argues that Rancière’s project of “art become life” can be employed as a common denominator of both theoretical frameworks, that of artification and that of the aesthetic regime of art. Nonetheless, the art to which Rancière’s notion primarily applies is different from art in the traditional sense, which seems to form the empirical basis of the notion of artification.

The Role Of Cax1 And Cax3 In Elemental Distribution And Abundance In Arabidopsis Seed, Tracy Punshon, Kendall Hirschi, Jian Yang, Antonio Lanzirotti, Barry Lai, Mary Lou Guerinot

Dartmouth Scholarship

The ability to alter nutrient partitioning within plants cells is poorly understood. In Arabidopsis (Arabidopsis thaliana), a family of endomembrane cation exchangers (CAXs) transports Ca²⁺ and other cations. However, experiments have not focused on how the distribution and partitioning of calcium (Ca) and other elements within seeds are altered by perturbed CAX activity. Here, we investigate Ca distribution and abundance in Arabidopsis seed from cax1 and cax3 loss-of-function lines and lines expressing deregulated CAX1 using synchrotron x-ray fluorescence microscopy. We conducted 7- to 10-μm resolution in vivo x-ray microtomography on dry mature seed and 0.2-μm resolution x-ray …

Systemic Propaganda As Ideology And Productive Exchange, Gerald Sussman

International & Global Studies Faculty Publications and Presentations

Informed by the works of Marx and his progeny (Lukács, Gramsci, Althusser) as well as more recent marxian scholarship, the purpose of this paper is to explore the role of ideology and propaganda in the production and circulation of commodities and in the informalization of the contemporary workplace, particularly in the context of the promotional economy, politics, and culture of the United States. The heightened functions of media and communication technologies mark the pinnacle expression of late capitalism—the production, reproduction and colonization of the sphere of consciousness as a necessary condition for the maintenance of the corporate state as it …

Institute for Sustainable Solutions Publications and Presentations

This report is a synthesis of ideas about what this new economy-in-society-innature could look like and how we might get there. Most of the ideas presented here are not new. The coauthors of this report have published them in various forms over the last several decades, and many others have expressed similar ideas in venues too numerous to mention. What is new is the timing and the situation. The time has come when we must make a transition. We have no choice. Our present path is clearly unsustainable. As Paul Raskin has said, "Contrary to the conventional wisdom, it is …
