Revising The Iowa Accreditation Process For Community Colleges: A Case Study , Jan Erickson Snyder Jan 2006

Revising The Iowa Accreditation Process For Community Colleges: A Case Study , Jan Erickson Snyder

Retrospective Theses and Dissertations

Iowa is one of the few states in the nation that is required by law to have a formalized process that accredits its community colleges. In February of 2005, the Iowa Department of Education's (DE) Division of Community Colleges and Workforce Preparation began a comprehensive review of the state accreditation process for Iowa's community colleges. This review was prompted by major changes in the criteria and processes of the North Central Association of Colleges and Schools - Higher Learning Commission (NCA-HLC) which was effective in January of 2005;The purpose of this case study was to collect, document, and ...


"A Solution To A Worrisome Problem": The Rhetoric Of Scientific Discourse In A Public Policy Dispute About The Environment , James Robert Heiman Jan 2006

"A Solution To A Worrisome Problem": The Rhetoric Of Scientific Discourse In A Public Policy Dispute About The Environment , James Robert Heiman

Retrospective Theses and Dissertations

The goal of this study is to demonstrate how rhetorical analyses of public discourse artifacts and practices reveal science as a civic discourse---with highly epideictic and deliberative purposes---that guides public policy decisions made by non-expert, civic leaders. Though typically recognized for its forensic function, little is written about how the epideictic function of scientific discourse politically performs in public policy debates about the environment. Nor is much written about the connection between the epideictic and deliberative functions of scientific discourse and the resolution of public controversies. To demonstrate the intersection of the political and scientific, I present a case study ...

Self-Representations And Power Relations In Peer Review Interactions: A Case Study Of Two International Students In A Composition Class, Lavinia Hirsu Jan 2006

Self-Representations And Power Relations In Peer Review Interactions: A Case Study Of Two International Students In A Composition Class, Lavinia Hirsu

Retrospective Theses and Dissertations

Peer review is a commonly used activity in cross-cultural composition classes; however, little research has investigated how NNSEs' (non-native speakers of English) self-perceptions and power relations reflect and are reflected in their peer discourse, more exactly in the use of social-interactional strategies and personal stance. In this microethnographic study, I followed two NNSEs working in dyads with two different peers (a native and a non-native speaker of English) for a rhetorical analysis assignment in a cross-cultural composition class. First I distributed a survey to the six participants in order to determine their perceptions of previous and hypothetical peer interactions, and ...

Daimler Dreams, Meghan H. Bullock Jan 2006

Daimler Dreams, Meghan H. Bullock

Retrospective Theses and Dissertations

Daimler dreams is a novel about Lois Lane. Her relationship with Superman is not the main focus of it; rather, it examines her personal history and the way that history impacts her present as a film critic for the local newspaper. The narrative deals, in part, with the effects of trauma and identity issues.


Female Wards, Feminism, And Mentorship In Mansfield Park And Jane Eyre, Miranda Mccullick Jan 2006

Female Wards, Feminism, And Mentorship In Mansfield Park And Jane Eyre, Miranda Mccullick

Retrospective Theses and Dissertations

Although a striking number of similarities exist between Jane Austen's Mansfield Park and Charlotte Bronte's Jane Eyre, the heroines of these novels provoke very different reactions regarding their qualifications as feminist heroines. While Jane Eyre is often celebrated as one of the most highly feminist characters in the women's literature canon, many critics read Fanny Price as ultimately succumbing to and reinforcing traditional, patriarchal values. This thesis examines the ways in which these heroines' roles as female wards in a patriarchal society influence their roles as feminist heroines and evaluates them as such using the following criteria ...


Towards A Dialogic Theory Of New Media Literacy, S. Scott Graham Jan 2006

Towards A Dialogic Theory Of New Media Literacy, S. Scott Graham

Retrospective Theses and Dissertations

Since the work of Gunther Kress, Cynthia Selfe, Anne Wysocki, the New London Group and others, many composition instructors are integrating the study and practice of new communication technologies into their pedagogy. This burgeoning amalgam of fields, which I call new media literacy studies, is heavily invested in extending first-year composition and literacy instruction to address the growing ubiquity of information communication technologies. This thesis begins with an exploration of the scope of these new media literacy theories, and argues for a new media literacy theory grounded in the dialogic theories of Mikhail Bakhtin and the Sophists. By bringing a ...

Motivation And Acquisition Of Pronunciation In Efl Students In El Salvador, Christian Enrique Meléndez

Retrospective Theses and Dissertations

This study examines the effect of pronunciation instruction and motivation in the acquisition of second language pronunciation in EFL students in El Salvador. Eighteen participants were given a pronunciation pre-test and a post-test. They received 20 minutes of pronunciation training each day for fifteen days. The training focused on the pronunciation of two different English sounds, /[O with line through the middle]/ and /-ed/ endings for the past of the regular verbs. The participants also completed a self-report motivation questionnaire containing nine different variables. Three different statistical analyses were used to analyze the data collected: paired t-tests, Cronbach's Alpha ...

Faster, Normal Or Slower?: The Effects Of Speech Rates On High-Intermediate Esl Learners' Listening Comprehension Of Academic Lectures, Fushun Le

Retrospective Theses and Dissertations

The purpose of this study is to 1) identify whether three speech rates (SR) (normal, faster and slower) have different effects on high-intermediate ESL learners' listening comprehension of academic lectures, and if so, to determine which SR is the most beneficial to the learners' comprehension; and 2) to identify learners' perception of SRs and reasons for lecture incomprehensibility. Eleven international students were asked to listen to three long academic lectures on unfamiliar topics and answer multiple choice comprehension questions, which was followed by a brief survey of their perception of the SR appropriateness and lecture difficulty. The original SRs of ...


Technical Communicator's Encroachment On Public Relations: A Report From The Field, Krysta Joellen Nibe Jan 2006

Technical Communicator's Encroachment On Public Relations: A Report From The Field, Krysta Joellen Nibe

Retrospective Theses and Dissertations

A survey was conducted to focus on technical communicators and their roles within organizations. The study utilized public relations encroachment theory and survey research to investigate five research questions relating to technical communication encroachment of public relations. The research found that there may be some encroachment occurring in public relations by technical communicators, but only in two roles: Problem-Solving Process Facilitator and Communication Facilitator. Additionally, the study found that a technical communicator's experience level was linked to encroachment. Less experienced technical communicators were more likely to perceive they encroach on public relations. Gender and education did not play a ...

Prefab And Parasitic Architecture : Architectural Solution Of The Future City Crisis (With Case-Study Design Projects), Bosuk Hur

Retrospective Theses and Dissertations

My thesis is basically about the concept of architecture, where humans, regarded as a living machine, will lead their lives in the future. This thesis aims to develop solutions to the problems (CO2, population, social level, sprawl phenomenon, and so on). I pictured the image of Laputa Island in Gulliver's travels in order to solve problems of the city. This is the definition of the Laputa. (Laputa: Floating island in the sky, mentioned in Gulliver's travels) Lebbeus Woods showed imaginary architecture in the future, which mentioned "floating housing" in his works such as "Aerial Paris," "Havana Project," and ...


Isolation And Characterization Of High Persistence Mutants Of Salmonella Enterica Serotype Typhimurium, Andrew Richard Slattery Jan 2006

Isolation And Characterization Of High Persistence Mutants Of Salmonella Enterica Serotype Typhimurium, Andrew Richard Slattery

Retrospective Theses and Dissertations

A small fraction of bacterial populations consist of "persistent" cells that are phenotypically distinct from the majority of cells by their ability to avoid killing by a variety of antimicrobial challenges. Persistence is distinct from resistance in that persistent cells are unable to grow in the presence of the antimicrobial agent or treatment, but resume growth after the selection has been removed. Presently, little is known about the genetic or physiological basis of persistence. In this study we demonstrate that Salmonella enterica serovar Typhimurium (S. typhimurium) displays the persistence phenotype. To better understand persistence in this important food-borne pathogen, we ...

Evaluation Of The Efficacy Of Extracorporeal Shock Wave Therapy (Eswt) On Osteoarthritis And Post-Eswt Analgesia In Animal Models, Jessica Ann Dahlberg

Retrospective Theses and Dissertations

Therapeutic use of extracorporeal shock wave therapy (ESWT) was first reported for the treatment of uroliths in humans in the 1970s and has been used in human orthopedics for over 10 years. ESWT has had promising results treating a wide variety of musculoskeletal diseases resulting in bone remodeling, neovascularization of bone-tendon interfaces, and orthopedic pain relief. ESWT has been applied to musculoskeletal diseases in animals in the United States for over 7 years. Although, ESWT has been used extensively in human and veterinary medicine, questions regarding efficacy and mechanism of action remain. Osteoarthritis is a significant cause of lameness in ...

Sequential Saccharification Of Corn Fiber By The Brown Rot Fungus, Gloeophyllum Trabeum, And Ethanol Production By Saccharomyces Cerevisiae, Mary Lynn Rasmussen Jan 2006

Sequential Saccharification Of Corn Fiber By The Brown Rot Fungus, Gloeophyllum Trabeum, And Ethanol Production By Saccharomyces Cerevisiae, Mary Lynn Rasmussen

Retrospective Theses and Dissertations

Ethanol production by corn wet-milling plants produces large quantities of the low-value, lignocellulosic co-product - corn fiber. A mixture of corn fiber combined with other by-products, including oil cake, steep liquor and stillage, is currently dried, pelletized and sold as corn gluten feed for dairy cattle. As wet-milling processes expand, additional uses of the fiber will be required to prevent an oversupply of animal feed. One approach for value-adding is to utilize corn fiber as a feedstock for production of more ethanol. Saccharification of the cellulose could liberate simple sugars for subsequent yeast fermentation to ethanol. Hydrolysis of corn fiber to ...


Use Of Precision Agriculture Technologies In Studying The Relationships Among Soil Ph, Calcium Carbonate Equivalent, Soybean Cyst Nematode Population Density, And Soybean Yield , Natalia Rogovska Jan 2006

Use Of Precision Agriculture Technologies In Studying The Relationships Among Soil Ph, Calcium Carbonate Equivalent, Soybean Cyst Nematode Population Density, And Soybean Yield , Natalia Rogovska

Retrospective Theses and Dissertations

Iron deficiency chlorosis (IDC) and soybean cyst nematode (SCN; Heterodera glycines) infestation are major factors that contribute to soybean (Glycine max Merr.) yield reduction in the Midwest. The IDC is often associated with soybean grown on high pH, calcareous soils. In addition, it was documented that SCN population density is higher in high pH soils. The objectives of this paper were to assess the proportion of within-field soybean yield and SCN variability that could be explained by soil pH, calcium carbonate equivalent (CCE), and a previously defined alkalinity stress index (ASI). Aerial images from 21 fields planted to SCN-resistant or ...

Retrospective Theses and Dissertations

The research presented and discussed within involves the development of novel biological applications of mesoporous silica nanoparticles (MSN) and an investigation of mesoporous material by transmission electron microscopy (TEM);A series of room-temperature ionic liquid (RTIL) containing mesoporous silica nanoparticle (MSN) materials with various particle morphologies, including spheres, ellipsoids, rods, and tubes, were synthesized. By changing the RTIL template, the pore morphology was tuned from the MCM-41 type of hexagonal mesopores to rotational moire type of helical channels, and to wormhole-like porous structures. These materials were used as controlled release delivery nanodevices to deliver antibacterial ionic liquids against Escherichia coli ...


Energy Expenditure In Lean And Obese Women: The Role Of Posture Allocation , Darcy Larae Johannsen Jan 2006

Energy Expenditure In Lean And Obese Women: The Role Of Posture Allocation , Darcy Larae Johannsen

Retrospective Theses and Dissertations

Obesity occurs when energy intake exceeds energy expenditure over an extended period of time. Low resting metabolic rate (RMR), or expending less energy at rest than persons of equivalent body size, is considered a risk factor for weight gain leading to obesity. However, because obese persons tend to have greater lean mass (LM) as well as fat mass (FM) than do lean individuals, absolute RMR tends to be higher, rendering the detection of initial impairments in RMR difficult. Purposes of this study were to determine resting energy expenditure (REE) in lean and obese women who were matched for LM and ...


Falling Upwards, Alicia Maria Hernandez Jan 2006

Falling Upwards, Alicia Maria Hernandez

Retrospective Theses and Dissertations

There exists a group of people known as the Winged who live in a city called Colonia, nestled in the mountains and by a high stone wall. The humans don't know about them, but the Winged were actually once humans themselves. The Winged life seems utopian. They don't age or get sick, they live in utter peace with each other, and they are free to do whatever they want with their lives. The only requirement their unofficial leader, Scio, mandates is that they task more humans by turning them into Winged. At one hundred and twenty years old ...


Fluorous-Tag Assisted Solution Phase Synthesis Of Mannose And Heptomannose Oligosaccharides And Study Of Their Binding Interactions Using Carbohydrate Microarray Technology , Firoz Ali Jaipuri Jan 2006

Fluorous-Tag Assisted Solution Phase Synthesis Of Mannose And Heptomannose Oligosaccharides And Study Of Their Binding Interactions Using Carbohydrate Microarray Technology , Firoz Ali Jaipuri

Retrospective Theses and Dissertations

Oligosaccharide synthesis is one of the challenging problems in carbohydrate chemistry. Carbohydrates are found in nature but they are present in heterogeneous form and in very small quantity. Over the past few decades chemical synthesis of carbohydrates has took off because of their biological properties. Since solution phase synthesis is very long and tedious, solid-phase synthesis took carbohydrate chemist to a new level. With the advent of automated solid phase synthesis developed by Seeberger and coworkers, many complex oligosaccharides were readily available for biological studies. The major drawback of solid-phase synthesis is it uses huge amount of sugar donors in ...

Production Of Vaccines And Vaccine Components In Corn , Sule Karaman

Retrospective Theses and Dissertations

Newly emerging infectious agents along with already existing ones, extended lifespan and increased population in the modern age, and the threat of biological warfare increase the demand for high amounts of pharmaceutical/diagnostic recombinant protein production. Plants are safe and cost efficient for production of recombinant pharmaceuticals for humans and livestock. This work investigated potential of corn to serve as a production and delivery vehicle for subunit vaccines and vaccine components. Highly immunogenic antigens LT-B and CT-B from enterotoxigenic strains of Escherichia coli ( E. coli) and Vibrio cholera (V. cholera ) were used in this study as vaccine/component candidates;This ...


Elements Of Representation Within Iowa Soil , Bronwyn Beatty-Hansen Jan 2006

Elements Of Representation Within Iowa Soil , Bronwyn Beatty-Hansen

Retrospective Theses and Dissertations

Representation is key to the field of Political Science. Behavior of representatives and conditional factors affect representation. Previous research is lacking in information about representation on a small scale. This paper hypothesizes that representation at the local rural level is also affected by behavior and conditional factors. This paper uses Iowa rural community and city council data to explore the relationship between behavioral and environmental factors and citizen satisfaction ratings. Correlation and regression analysis was run on data from the RDI project and CCS project. The results show relationships between economic factors and population and the dependent variables, citizen satisfaction ...


Paired, Developmental Learning Communities: A Case Study Of One Institution , Kelly Jo Krogh Faga Jan 2006

Paired, Developmental Learning Communities: A Case Study Of One Institution , Kelly Jo Krogh Faga

Retrospective Theses and Dissertations

The purpose of this study was to examine a paired, developmental learning community to understand how it enhances learning at a selected community college---Metropolitan Community College in Omaha, Nebraska. Learning communities are defined as purposeful restructuring of an undergraduate curriculum that thematically link or cluster courses together and enroll a common group of students (MacGregor & Smith, 2005). Thus, the research focused on students in a paired, developmental learning community. Developmental learning communities consist of two developmental classes that are linked with other courses at the college and enroll a common group of students;The primary focus was to view paired, developmental learning communities through the eyes of at-risk students who participated in them. To complement this part of the research, a persistence study was included in the findings that examined the percentage of students in a paired, developmental ...


The Role Of Proximal And Distal Influences On Relationship Termination Adjustment In College Students , Robert Bruce Hensley Jan 2006

The Role Of Proximal And Distal Influences On Relationship Termination Adjustment In College Students , Robert Bruce Hensley

Retrospective Theses and Dissertations

The purpose of the present study was to investigate gender and age differences in dealing with a romantic relationship breakup, as well as to investigate the role that distal (childhood events and childhood attachment) and proximal (personality, perceived stress, coping, and adult attachment) influence one's adjustment to an ended romantic relationship. Participants for this study included 252 (160 women and 92 men) college students, with age ranges from 18 to 39. Two (Age) X Two (Gender) analyses of covariance were computed to assess mean differences for all variables. Women reported higher Neuroticism, Extraversion, and Agreeableness scores than men, whereas ...


Repair Of Endonuclease- And Transposon-Induced Dna Double Strand Breaks By Host Factors In Arabidopsis , Zhuying Li Jan 2006

Repair Of Endonuclease- And Transposon-Induced Dna Double Strand Breaks By Host Factors In Arabidopsis , Zhuying Li

Retrospective Theses and Dissertations

The maize Ac/Ds transposable elements are members of the hAT transposon family. Ac/Ds transpose in diverse species and via a mechanism similar to that involved in V(D)J recombination. Here, we studied the repair of Ds transposition-induced hairpins by host factors in Arabidopsis. The results indicate that AtKu could position hairpin-opening to sites close to the hairpin apex. In the absence of AtMre11 or AtKu70, repair junctions have a higher frequency of small deletions (3-10bp) and larger deletions (11-50bp), respectively. Comparison of the repair of I-SceI- and Ds-induced DSB indicates that Ac transposase could influence Ds-induced DSB ...
