The Unveiling Of W.E.B. Dubois : A Qualitative Content Analysis Of Diverse Interpretations Of The Works And Life Of W.E.B. Dubois, Sonja Lee Bock

Dissertations and Theses @ UNI

W. E. B. Du Bois is one of the founding fathers of sociology. Despite his many contributions, he was not included in the sociological canon and given the recognition he deserves. Du Bois was an African-American scholar whose contributions lead to the development of the first school of sociology in the United States, although he has generally not been recognized for it. My research explores how the effects of the veil contribute to the interpretations of Du Bois. To investigate this question, I will perform a qualitative content analysis of selected publications by Dubosian experts who have written extensively about …

Recalcitrant Arguments, Kiranjeet Kaur Dhillon

Dissertations and Theses @ UNI

On January 26, 2011, Reuters photojournalist Amr Abdallah Dalsh took an image of a unknown veiled woman gesturing at Dalsh and his camera. Using TinEye, a reverse image search engine, I found that 86 circulations and 22 recirculations of the photo were primarily in the United States. US graphic artist Nick Bygon created one of the recirculations, which primarily appeared on US blogs. The photo achieved this level of circulation in the US because it is consistent with, and therefore legible within the symbolic language, of the liberal democratic order. Similar to “Migrant Mother” and “Tank Man”, the photo is …

Population Genetics Of Thomomydoecus Minor: Ectoparasitic Chewing Lice On Thomomys Bottae Pocket Gophers Of The Rio Grande Valley In New Mexico, Sheree Elizabeth Harper

Dissertations and Theses @ UNI

Thomomydoecus minor is an ectoparasitic chewing louse that lives in intimate association with the pocket gopher Thomomys bottae. Chewing lice are wingless, obligate, host specific parasites that spend their entire life cycle on the fur of their host. Pocket gophers are fossorial and asocial, cut off for most of their lives even from members of their own species. Thus, the life histories of both chewing lice and pocket gophers have been predicted to limit transmission of lice from host to host, thus limiting gene flow among louse infrapopulations found on different hosts and increasing the effect of louse population …

Long-Term, Low-Dose Exposure Of People Residing In Arsenic Affected Areas Of Iowa: A Cross-Sectional Analytical Study, Junu Shrestha

Dissertations and Theses @ UNI

Arsenic contamination in the ground water source is a major problem throughout the world. Epidemiological studies show that long-term arsenic exposure in drinking water, even at low concentrations, can lead to chronic toxicity problems and negative health outcomes. In the United States, private wells are not mandated to comply with the drinking water standards that piped water is, putting many people at risk. This study focused on monitoring of arsenic contamination of private well water, hair samples, and questionnaire based surveys. Of the 260 private well owners selected from 13 counties in Iowa who were invited to participate in the …

However, few studies have reported the use of blended learning in the high school setting. This study used quantitative methods to measure student attitudes and learning of science content in both a treatment and control group consisting of 9th grade Physical Science classes. Students in the treatment group experienced one semester of blended learning by using online science modules to supplement their in-class learning while the control group continued to have only …

From Sidebets To Sideshow: The Influence Of Gambling On The Development Of Professional Wrestling In America, 1870-1911, Lee Casebolt

Dissertations and Theses @ UNI

While boxing and baseball have been common subjects of historical study, other sports of the nineteenth century have been comparatively neglected by historians. Professional wrestling, in particular, has received very little attention as a sport, as opposed to its twentieth century “sports entertainment” incarnation. What attention it has received has most commonly been through the lens of social history, focusing on wrestling as theater or its psychosexual overtones. Missing from its history is any consideration of the economic factors which influence the evolution of any professional endeavor. This paper explores the relationship between a wrestler’s payment and performance. Specifically, it …

Effect Of Limb Circumference On Intramuscular Cooling During And Following An Ice Bag Application After Exercise, Marcus A. Sojka

Dissertations and Theses @ UNI

Bird Use Of Heterogeneous Native Prairie Biofuel Production Plots, Jarrett D. Pfrimmer

Dissertations and Theses @ UNI

Changing land use practices and agricultural intensification have driven the loss of >90% of native grassland habitats in the Midwestern U.S.A. Consequently, grassland birds have declined more drastically than any other North American guild. Current biofuel production systems in the Midwest rely on high input monoculture crops that provide little habitat value to most grassland birds. The Tallgrass Prairie Center at the University of Northern Iowa is exploring the feasibility of growing and harvesting diverse mixes of native prairie vegetation for use as a sustainable biofuel in a manner that also provides high quality bird habitat. In 2009, 48 research …

Play, Collaborate, Break, Build, Share: 'Screwing Around' In Digital Pedagogy, Katherine D. Harris

Faculty Research, Scholarly, and Creative Activity

Digital Humanities has become a “hot” topic in academia over the last few years (as of 2012), primarily in research and scholarship. While many push forward into new realms of using technology to articulate cool findings, others at non research intensive universities are moving forward with engaging their undergraduate students in var ious forms of Digital Pedagogy, a facet of Digital Humanities. Single day bloom and fade projects, individual assignments, and larger scaffolded projects all comprise Digital Humanities curriculum. Here, I provide examples of all three types of projects an d include a discussion about risk, play, and productive failure …

Quasi-Experimental Evaluation Of Undergraduate Learning In A Multidimensional Wellness Course, Kristi Leonard

Dissertations and Theses @ UNI

Introductory wellness courses are common among American institutions of higher education. These courses are typically of a unidimensional approach, focusing on just the physical component of wellness. Some wellness educators would argue that a multidimensional approach is a richer and more valuable learning experience. Furthermore, technology has played a larger role in wellness education, as it is being created, developed, and implemented into the field. Therefore, college wellness educators and curriculum designers need to determine the implications for both online and face-to-face instructional methods in their execution of teaching the holistic concept of wellness to their students.

The purpose of …

The Role Of Self And Parental Criticism In Non-Suicidal Self-Injury, Brooke Aleece Ammerman

Dissertations and Theses @ UNI

Non-suicidal self-injury (NSSI) is found at high rates among adolescents and young adults, and often produces many negative consequences, warranting additional research (Yates, 2004). Parental criticism and self-criticism may greatly influence the likelihood of NSSI in these populations (Wedig & Nock, 2007), but the relationship needs to be expanded upon. The purpose of the current study was to address this need by measuring self-criticism, perceived parental criticism, and parent-reported criticism among adolescents and young adults. Results suggest that levels of self-criticism and perceived expressed emotion may influence whether or not an individual engages in NSSI. One particular aspect of self-criticism, …

Eating Soviet: Food And Culture In The Ussr, 1917–1991, Anton Masterovoy

Dissertations, Theses, and Capstone Projects

This dissertation argues that the best way to understand the nature of Soviet history is through the prism of food. Soviet citizens were encouraged to see the availability of food as the main measure of success for the construction of a new, Soviet civilization. The disappointment with the inability of the Soviet government to provide the quantity, quality and variety of food that the Soviet consumers expected was one of the major causes for the collapse of the USSR. The first chapter addresses the reasons why and how so unlikely a food as sausage became and remains the primary Russian …

Components Of The Complete Blood Count As Risk Predictors For Coronary Heart Disease: In-Depth Review And Update, Mohammad Madjid, Omid Fatemi

The Texas Heart Institute Journal

Atherosclerosis is an inflammatory disease, and several inflammatory biomarkers, such as C-reactive protein, have been used to predict the risk of coronary heart disease. High white blood cell count is a strong and independent predictor of coronary risk in patients of both sexes, with and without coronary heart disease. A high number of white blood cells and their subtypes (for example, neutrophils, monocytes, lymphocytes, and eosinophils) are associated with the presence of coronary heart disease, peripheral arterial disease, and stroke. The coronary heart disease risk ratios associated with a high white blood cell count are comparable to those of other …

Endovascular Treatment Of Acute Type B Dissection Complicating Aortic Coarctation, Seyed Ebrahim Kassaian, Kyomars Abbasi, Mehdi Mousavi, Mohammad Sahebjam

The Texas Heart Institute Journal

Surgical treatment poses a high risk to patients with concomitant aortic coarctation and dissection, and an interventional approach could be an alternative. We describe the case of a 52-year-old man with a long history of untreated hypertension and aortic coarctation who emergently presented at our institution with an acute Stanford type B dissection. The patient's elevated serum creatinine level, perfusion deficit in the right lower limb, and hypertension did not respond to medical therapy, and he did not consent to surgery. By endovascular means, we used a self-expandable stent-graft to cover the entry point of the dissection; then, we deployed …

Coronary Artery Diameter Related To Calcium Scores And Coronary Risk Factors As Measured With Multidetector Computed Tomography: A Substudy Of The Accuracy Trial, Yasmin S Hamirani, Khurram Nasir, Emil Avanes, Jigar Kadakia, Matthew J Budoff

The Texas Heart Institute Journal

Arterial remodeling, an early change of atherosclerosis, can cause dilated arterial diameter. We measured coronary artery diameter with use of noncontrast 64-slice multidetector computed tomography (MDCT), and studied its association with coronary artery calcium levels and traditional coronary risk factors.

We included 140 patients from the ACCURACY trial whose noncontrast MDCT images showed measurable coronary arteries. Using 3 measurements of left main coronary artery (LMCA) and right coronary artery (RCA) diameters within 3 mm of the ostium, we associated the results with traditional coronary risk factors and calcium scores.

The prevalence of LMCA and RCA calcium was 22% and 51%, …

Feasibility Of Temporary Biventricular Pacing After Off-Pump Coronary Artery Bypass Grafting In Patients With Reduced Left Ventricular Function, Daniel Y Wang, Lauren A Kelly, Marc E Richmond, T Alexander Quinn, Bin Cheng, Michelle D Spotnitz, Santos E Cabreriza, Yoshifumi Naka, Allan S Stewart, Craig R Smith, Henry M Spotnitz

The Texas Heart Institute Journal

In selected patients undergoing cardiac surgery, our research group previously showed that optimized temporary biventricular pacing can increase cardiac output one hour after weaning from cardiopulmonary bypass. Whether pacing is effective after beating-heart surgery is unknown. Accordingly, in this study we examined the feasibility of temporary biventricular pacing after off-pump coronary artery bypass grafting.

The effects of optimized pacing on cardiac output were measured with an electromagnetic aortic flow probe at the conclusion of surgery in 5 patients with a preoperative mean left ventricular ejection fraction of 0.26 (range, 0.15–0.35). Atrioventricular (7) and interventricular (9) delay settings were optimized in …

Neutrophil In Viral Infections, Friend Or Foe?, Brandon D. Drescher, Fengwei Bai

Faculty Publications

Polymorphonuclear leukocytes or neutrophils are the first immune cells to the site of injury and microbial infection. Neutrophils are crucial players in controlling bacterial and fungal infections, and in particular secondary infections, by phagocytosis, degranulation and neutrophil extracellular traps (NETs). While neutrophils have been shown to play important roles in viral pathogenesis, there is a lack of detailed investigation. In this article, we will review recent progresses toward understanding the role of neutrophils in viral pathogenesis. (C) 2012 Elsevier B.V. All rights reserved.
