Management Of Intra-Aortic Balloon Pump Entrapment: A Case Report And Review Of The Literature, Gerard J Fitzmaurice, Anton Collins, Haralambos Parissis Jan 2012

Management Of Intra-Aortic Balloon Pump Entrapment: A Case Report And Review Of The Literature, Gerard J Fitzmaurice, Anton Collins, Haralambos Parissis

The Texas Heart Institute Journal

An intra-aortic balloon pump is one of the most valuable tools in the cardiac surgeon's armament to assist in the management of the failing heart. Despite its widespread use, there are associated risks and complications, one of which is balloon rupture with associated entrapment. Numerous approaches for dealing with this complication have been described; here we review the previous experience with intra-aortic balloon pump entrapment and discuss potential management, with particular reference to a recent case of our own.

The Effects Of Scenario Planning On Participant Perceptions Of Learning Organization Characteristics, Melissa Haeffner, Deanna Leone, Laura Coons, Thomas Chermack Jan 2012

The Effects Of Scenario Planning On Participant Perceptions Of Learning Organization Characteristics, Melissa Haeffner, Deanna Leone, Laura Coons, Thomas Chermack

Environmental Science and Management Faculty Publications and Presentations

Scenario planning is often used by organizations to think about future uncertainties. However, what it does in terms of changing perceptions is diffi cult to assess and quantify. To address this need, this article builds on previous studies documenting the effectiveness of scenario planning. Specifi cally, this article contributes to the data on perceptions of learning organization characteristics. This study compiles quantitative data gathered from 133 individuals working in 10 United States companies who participated in scenario planning. The Dimensions of the Learning Organization Questionnaire (DLOQ) instrument was used in a pre- and post-test research design and differences were analyzed …

Pig (Sus Scrofa) Exploitation At Hallan Çemi, Southeastern Anatolia: Proposing An Alternative Model, Ximena Lemoine Jan 2012

Pig (Sus Scrofa) Exploitation At Hallan Çemi, Southeastern Anatolia: Proposing An Alternative Model, Ximena Lemoine

University Honors Theses

Hallan Çemi presents itself as a unique site to study the transitional period before the onset of agriculture in the Near East. The site fails to fit nicely into demographic or environmental models that have widely been accepted for the region. Hallan Çemi thus represents the potential to study innovative human strategies for subsistence, and to provide insight into the processes that led to the eventual adoption of agriculture only a few millennia later. Richard Redding and Michael Rosenberg presented one such innovative strategy for pig exploitation at this site with their New Guinean model (Redding and Rosenberg 1998; Rosenberg …

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 Jan 2012

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 Jan 2012

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.

Instant Canons: Film Festivals, Film Criticism, And The Internet In The Early Twenty-First Century, Morgen Ruff Jan 2012

Instant Canons: Film Festivals, Film Criticism, And The Internet In The Early Twenty-First Century, Morgen Ruff

University Honors Theses

Film festivals have been major events on the yearly film calendar since the first international festival at Venice in 1938. A handful of events--Cannes, Berlin, Venice, and Rotterdam, among others--have traditionally dominated discussion, although there are several parallel circuits within the festival world that generate different types and degrees of discourse among critics and audiences. Popular film criticism, concurrent with the recent crisis in print journalism, has undergone a broad shift toward the online sphere during the first decade of the twenty-first century, which has engendered new forms of criticism and consensus, such as the review aggregator. This thesis examines …

Effectiveness Of Multiple Restoration Techniques In Reducing The Abundance Of Kentucky Bluegrass And Smooth Bromegrass In The Northern Great Plains, Corie Beth Lund Jan 2012

Effectiveness Of Multiple Restoration Techniques In Reducing The Abundance Of Kentucky Bluegrass And Smooth Bromegrass In The Northern Great Plains, Corie Beth Lund

Range Science

Kentucky bluegrass (Poa pratensis L.) and smooth bromegrass (Bromus inermus L.) are cool-season, perennial, non-native grasses that are invading North Dakota grasslands. Two studies evaluated different restoration techniques aimed at reducing Kentucky bluegrass and smooth bromegrass abundance. The initial study, located on five different plant communities in a mixed grass prairie near Mandan, ND, noted some success at reducing Kentucky bluegrass through a combination of fire and chemicals. Therefore, a second study was initiated near Lisbon, ND to evaluate the effectiveness of fire and herbicides, alone or in combination, and the sequence for applying fire and herbicide. These treatments were …

Fire And Nitrogen Effects On A Purple Threeawn-Dominated Plant Community In The Northern Great Plains, Dustin Strong Jan 2012

Fire And Nitrogen Effects On A Purple Threeawn-Dominated Plant Community In The Northern Great Plains, Dustin Strong

Range Science

Purple threeawn (Aristida purpurea Nutt. varieties) is a native grass capable of rapidly increasing on rangelands, forming near monocultures, creating a stable state. Rangelands throughout the Great Plains and Intermountain West have experienced increases in purple threeawn abundance, leading to reductions in overall forage quality and community diversity. Our objectives were to: 1) examine prescribed fire and nitrogen as tools to shift species composition in a purple threeawn invaded community, 2) reveal vegetation management strategies appropriate for reducing purple threeawn abundance 3) quantify fire effects on purple threeawn plant characteristics and 4) determine the relationship between purple threeawn survival and …

Timing Is Everything : How Environmental Change May Disrupt The Timing Of Plant-Pollinator Interactions, Michelle Jene Solga Jan 2012

Timing Is Everything : How Environmental Change May Disrupt The Timing Of Plant-Pollinator Interactions, Michelle Jene Solga

Range Science

Ecosystems are experiencing environmental change brought about by warming temperatures, altered precipitation, and increasing atmospheric CO2, among other factors. These changes could alter interspecies’ relationships, including those between plants and pollinators. One important change may be to the timing of when flowers bloom and when pollinators are active. Environmental cues drive the phenology of many flowers and insect pollinators, so an alteration in timing for either species could jeopardize the plant-pollinator relationship. Previous studies indicate that many plant species have changed flowering dates in response to an environmental cue, but the response is species specific. Some pollinators may not be …

Whose Budget? Our Budget? Broadening Political Stakeholdership Via Participatory Budgeting, Celina Su Jan 2012

Whose Budget? Our Budget? Broadening Political Stakeholdership Via Participatory Budgeting, Celina Su

Publications and Research

In this thought piece, I attempt to contextualize New York City’s inaugural participatory budgeting (PB) process in the larger landscape of American political participation. I discuss how the bottom-up way in which stakeholders wrote the process’s rules in the first place, alongside the core role played by the two lead organizations, helped to broaden notions of stakeholdership among constituents. Ultimately, the first year’s primary achievement regarding political participation was not a specific set of outcomes, but a debut as an unfinished form of governance—one that began to engage traditionally marginalized constituents, to trigger their political imagination, and to prompt them …

Hyphens For Disambiguating Phrases: Effectiveness For Young And Older Adults, Inge Anema, Loraine Obler Jan 2012

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 …

Advancing The Human Right To Housing In Post-Katrina New Orleans: Discursive Opportunity Structures In Housing And Community Development, Leigh Graham Jan 2012

Advancing The Human Right To Housing In Post-Katrina New Orleans: Discursive Opportunity Structures In Housing And Community Development, Leigh Graham

Publications and Research

In post-Katrina New Orleans, housing and community development (HCD) advocates clashed over the future of public housing. This case study examines the evolution of and limits to a human right to housing frame introduced by one nongovernmental organization (NGO). Ferree’s concept of the discursive opportunity structure and Bourdieu’s social field ground this NGO’s failure to advance a radical economic human rights frame, given its choice of a political inside strategy that opened up for HCD NGOs after Hurricane Katrina. Strategic and ideological differences within the field limited the efficacy of this rights-based frame, which was seen as politically radical and …

Razing Lafitte: Defending Public Housing From A Hostile State, Leigh Graham Jan 2012

Razing Lafitte: Defending Public Housing From A Hostile State, Leigh Graham

Publications and Research

The contentious politics of the demolition of Lafitte public housing in post- Katrina New Orleans and its replacement with mixed-income properties is a telling case of the strategic conflicts housing advocates face in public housing revitalization. It reveals how the qualified outcomes of HOPE VI interact with local institutional and historical circumstances to confound the equity and social justice goals of housing and community development advocates. It shows the limits to public housing revitalization as an urban recovery strategy when hostile government leadership characterizes a region, and the state is recast as an adversary rather than revitalization partner. This case …

Growing Cities Depend On Ecosystem Services, David E. Ervin, Darrell Brown, Heejun Chang, Veronica Dujon, Elise F. Granek, Vivek Shandas, J. Alan Yeakley Jan 2012

Growing Cities Depend On Ecosystem Services, David E. Ervin, Darrell Brown, Heejun Chang, Veronica Dujon, Elise F. Granek, Vivek Shandas, J. Alan Yeakley

Geography Faculty Publications and Presentations

Many studies have documented the growing fragility of a majority of the globe's ecosystems. Policymakers and resource managers often frame such ecosystem challenges as primarily about protecting natural systems in rural areas. However, that conception misses a key part of the story: the rapid growth of urbanizing areas. Home to more than 50 percent of the world's human population for the first time in modern history, urbanizing regions concentrate pressure on ecosystem services, which are necessary to sustain healthy urban living conditions and vibrant commerce. This dramatic urbanization presents both challenges and opportunities for novel ecosystem services management. A transdisciplinary …

Digital Video: Engaging Students In Critical Media Literacy And Community Activism, Jessie Daniels Jan 2012

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 Jan 2012

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 …

Three Stravinsky Analyses: Petrushka, Scene 1 (To Rehearsal No. 8); The Rake’S Progress, Act Iii, Scene 3 (“In A Foolish Dream”); Requiem Canticles, “Exaudi”, Joseph N. Straus Jan 2012

Three Stravinsky Analyses: Petrushka, Scene 1 (To Rehearsal No. 8); The Rake’S Progress, Act Iii, Scene 3 (“In A Foolish Dream”); Requiem Canticles, “Exaudi”, Joseph N. Straus

Publications and Research

Most published work in our field privileges theory over analysis, with analysis acting as a subordinate testing ground and exemplification for a theory. Reversing that customary polarity, this article analyzes three works by Stravinsky (Petrushka, The Rake’s Progress, Requiem Canticles) with a relative minimum of theoretical preconceptions and with the simple aim, in David Lewin’s words, of “hearing the piece[s] better.”

Topic Modeling And Figurative Language, Lisa M. Rhody Jan 2012

Topic Modeling And Figurative Language, Lisa M. Rhody

Publications and Research

Located at the center of Jorie Graham’s collection The End of Beauty, “Self Portrait as Hurray and Delay” crafts a portrait of the artist, poised at a precarious moment in which thought begins to take shape. Like Penelope, Graham entertains the illusion, if only momentarily, of a choice between bringing a creative impulse into form or allowing it to come undone. A weaver of language, Graham subtly, deftly, but unsuccessfully attempts to delay the inevitable moment in poetic creation in which complexity of thought adopts form through language, and so realized is also reduced. In The End of Beauty, the …

Transporting And Disposing Of Wastewater From North Dakota Oil Producers, Qingqing Yin Jan 2012

Transporting And Disposing Of Wastewater From North Dakota Oil Producers, Qingqing Yin

Agribusiness and Applied Economics

North Dakota’s oil boom is aided by a new technology, fracking. But this technology implies large amounts of wastewater. The methods of dealing with this wastewater are now an issue. Currently, North Dakota locks it into deep injection wells in the Bakken formation. With the development of membrane technologies to treat wastewater, it may be feasible to treat the wastewater and reuse it. This study uses a mathematical programming model to minimize the total cost of dealing with wastewater using three methods - deep well injection, on-site treatment, and off-site treatment. The model results show it is cost-effective to use …

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 Jan 2012

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, …

The Relationship Between Water Pollution And Economic Growth Using The Environmental Kuznets Curve: A Case Study In South Korea, Jaesung Choi Jan 2012

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 …
