Focusing On Process And History: Path Dependence, Paul Donnelly

Articles

In recognition of the calls for more processual and historically informed organizational theorizing, this chapter considers the notion of path dependency, an approach which holds that a historical path of choices has the character of a branching process with a self-reinforcing dynamic such that preceding steps in a particular direction induce further movement in the same direction, thereby making the possibility of switching to some other previously credible alternative more difficult. Path dependence seeks to assess how process, sequence and temporality can be best incorporated into explanation, the focus of the researcher being on particular outcomes, temporal sequencing and the …

Predicting The Perforation Response Of Honeycomb Sandwich Panels Using Ballistic Limit Equations, William P. Schonberg, Frank Schäfer, Robin Putzar

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Man-made debris from previous spacecraft missions poses a serious threat to spacecraft that are launched to operate in Earth orbit because it can strike such spacecraft at extremely high velocities and consequently damage mission-critical systems. Most satellites are constructed with honeycomb sandwich panels as their primary structural elements. to be able to perform a risk analysis, it is important to know, in the event of such a meteoroid or orbital debris particle impact, whether or not the impacting particle or parts thereof will exit the rear of the sandwich panel. a recently developed set of ballistic limit equations for two …

Risk Indexes For Draft Ccl3 Chemicals, J. Alan Roberson, Matthew Lueders, Craig Adams, Jeffrey S. Rosen

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

To supplement the processes used for developing the draft third Contaminant Candidate List (CCL3) and better inform decisions made by the US Environmental Protection Agency on future CCLs, the authors offer an evaluation tool for efficiently synthesizing, visualizing, and organizing data for effective comparisons among contaminants. Graphical presentations of health effects-occurrence indexes were developed for more than 300 chemical contaminants, including those on the draft CCL3. a risk indexes framework was then used to elucidate the extent of available data, the data quality, and the underlying uncertainties for occurrence and toxicity. Choosing the appropriate contaminant for regulation is a complex …

Mobile Speed Estimation For Broadband Wireless Communications Over Rician Fading Channels, Y. Rosa Zheng, Chengshan Xiao

Electrical and Computer Engineering Faculty Research & Creative Works

In this paper, a new algorithm is proposed to estimate mobile speed for broadband wireless communications, which often encounter large number of fading channel taps causing severe intersymbol interference. Different from existing algorithms, which commonly assume that the fading channel coefficients are available for the speed estimators, the proposed algorithm is based on the received signals which contain unknown transmitted data, unknown frequency selective fading channel coefficients possibly including line-of-sight (LOS) components, and random receiver noise. Theoretical analysis is first carried out from the received signals, and a practical algorithm is proposed based on the analytical results. The algorithm employs …

Resilient Moduli Of Granular Base Materials Using A Modified Type 5 Gradation, David Newton Richardson, S. M. Lusher

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

The Missouri Department of Transportation (MoDOT) in collaboration with the Missouri Limestone Producers Association (MLPA) was interested in determining what effect a change in the Type 5 aggregate base gradation specification would have on the resilient modulus (Mr) of said aggregate. The proposed change would lower the minimum allowable total percentage of material passing the #4 (4.75 mm mesh) sieve from 35% to 25%, and the #30 (0.600 mm mesh) sieve from 10% to 5%. The remainder of the gradation specification would remain unchanged. The rationale for this proposed change is that some aggregate producers believe the change could help …

Quick Test For Percent Of Deleterious Material, David Newton Richardson

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

The Missouri Department of Transportation (MoDOT) is considering the replacement of its deleterious materials test method (TM-71) with test methods that are more objective. MoDOT contracted with the Missouri University of Science and Technology (Missouri S&T) to develop a system of test methods. Nine quarry/ledge samples representing seven geologic formations (four limestones and three dolomites) were supplied by MoDOT. The ledge samples represented three aggregates each for use in concrete, asphalt, and granular base. Samples with controlled contamination were also tested, bringing the total to 18. The aggregates were subjected to fifteen test methods. This data, coupled with MoDOT historical …

Resilient Moduli Of Typical Missouri Soils And Unbound Granular Base Materials, David Newton Richardson, Thomas M. Petry, Yu-Ning Louis Ge, Y. P. Han, S. M. Lusher

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

The objective of this project is to accurately determine the resilient moduli for common Missouri subgrade soils and unbound granular base materials in accordance with the AASHTO T 307 test method. The test results included moduli data from 27 common subgrade soils out of the 99 Missouri soil associations and from 5 unbound granular bases. These materials were tested at their optimum water content and at an elevated water content, which would normally occur as a worse case scenario during the life of a pavement. The five unbound granular base materials were tested at two different gradations (high and low …

Preliminary Investigation Of Novel Bone Graft Substitutes Based On Strontium-Calcium-Zinc-Silicate Glasses, D. Boyd, G. Carroll, Mark R. Towler, C. Freeman, P. Farthing, I. M. Brook

Chemical and Biochemical Engineering Faculty Research & Creative Works

Bone graft procedures typically require surgeons to harvest bone from a second site on a given patient (Autograft) before repairing a bone defect. However, this results in increased surgical time, excessive blood loss and a significant increase in pain. In this context a synthetic bone graft with excellent histocompatibility, built in antibacterial efficacy and the ability to regenerate healthy tissue in place of diseased tissue would be a significant step forward relative to current state of the art philosophies. We developed a range of calcium-strontium-zinc-silicate glass-based bone grafts and characterized their structure and physical properties, then evaluated their in vitro …

Administrative Mentoring: An Investigation Of Practicing Principals' Perceptions Of The Role Mentors Played In Their Professional Development And Job Satisfaction, Lisa M. Remy

Dissertations and Theses @ UNI

Researchers have alluded to the power of mentorship to connect the new administrator to the organization. Following the lead of business, the field of education is now recognizing mentoring as a critical component of effective leadership development. Daresh (2001) suggests there is a need for a more practical and effective approach to prepare the leaders of our schools. New administrators have little choice but to experience on-the-job training, without any formal support in place. Administrative mentoring programs are growing in attention due to the projected principal shortages, concerns about qualified candidates, and the changing role of the building level principal. …

The Relationship Between Cardiovascular Fitness And Risk Factors Of Type 2 Diabetes In Adults, La Toshia Burrell

Control Of Myosin Motor Activity And Actin Filament Translation By Alteration Of Assay Reducing Potential, Siva Krishna Nalabotu

Theses, Dissertations and Capstones

The use of biomolecular motors for nanotechnological applications has been impaired by an inability to control biomolecular motor activity in a temporal fashion. Previous data has suggested that myosin activity can be modulated by inducing changes in the degree of myosin oxidation. The hypothesis of this study is that myosin motor activity can be regulated by altering the amount of antioxidants and reducing agents present in assay solution. To test this hypothesis we systematically altered the concentration of reducing agents and examined the effects of these changes on myosin-dependent actin filament translation. Our findings indicate that myosin activity can be …

Positions Of Power, Abjection And Constraint: Evaluating Discursive Attempts To Save An Other, Ruth Janet Beerman

Dissertations and Theses @ UNI

Beginning from the presumption that questions of agency are important, this thesis interrogates notions of who can speak, how to speak, and what constitutes agency. Feminist rhetorical theory operates as a key avenue to evaluate negotiating positions of power and privilege when examining how to liberate oppressed groups. By utilizing feminist conceptions of the body as well as theories of performance and personae, I examine how rhetorical theory contributes to such understandings where one speaks about an other. Finally, the war in Iraq serves as a case study to illustrate my theory.

A Test Of Ajzen’S Theory Of Planned Behavior: Predicting Students’ Intentions Toward Joining An Army Rotc Program, Jason Hornberg

Dissertations and Theses @ UNI

Young adults' expressed interest toward joining The Unites States Armed Forces has been decreasing since the 1990's. This downward trend has negatively influenced the recruitment of enlisted soldiers into the military as well as the enrollment of young adults into officer production programs like the Reserve Officer Training Course (ROTC). In an attempt to understand and overcome the effects of this trend, behavioral scientists have begun using behavioral theories to predict young adults' intention toward joining the military. One theory that has been frequently used to predict intention and behavior is Ajzen's theory of planned behavior. Ajzen' s theory of …

Gorenstein Flat Dimension Of Complexes, Alina Iacob

Mathematical Sciences: Faculty Publications

We define a notion of Gorenstein flat dimension for unbounded complexes over left GF-closed rings. Over Gorenstein rings we introduce a notion of Gorenstein cohomology for complexes; we also define a generalized Tate cohomology for complexes over Gorenstein rings, and we show that there is a close connection between the absolute, the Gorenstein and the generalized Tate cohomology.

Institutional Racism And Public Policy : A Critical Discourse Analysis Of The War On Drugs, Kyle L. Mahannah

Dissertations and Theses @ UNI

Through reviewing the concept of institutional racism, I examine how this concept has been employed in the discourse on the war on drug. Moreover, I explore how this term has been employed by opponents and proponents on the war on drugs. First, I explore how the term 'institutional racism' is defined by various authors and scholars. I then reviewed how the United State Supreme Court has set precedents regarding intentional and unintentional discrimination. I also investigate how the concept of institutional racism is used in the discourse on American institutions of education, economics, law, and politics. l then review how …

Investigating The Potential Contributors To Non-Suicidal Self-Injury: Stress, Emotional Dysregulation, And Alexithymia, Kelly K. Espenschade

Dissertations and Theses @ UNI

Research has investigated perceived stress, non-suicidal self-injury (NSSI), emotional dysregulation, and alexithymia independently. However, there have been no studies to date that have simultaneously examined the relationship among all these variables. The purpose of this study was to examine these variables among those who had or had not engaged in NSSI. Five hundred seventy-seven college students completed self report measures of non-suicidal self-injury, perceived stress level, emotional dysregulation, and alexithymia. As hypothesized, those who had engaged in self-harm behaviors reported higher levels of perceived stress, emotional dysregulation, and alexithymia. There were no gender differences except on perceived stress levels, where …

Social Support And Work-School Conflict: A Daily Study, Eric John Faurote

Dissertations and Theses @ UNI

The goal of this study was to examine within-person associations between work-school conflict (WSC), social support at work, job satisfaction, and negative affect. There were 108 undergraduates for a Midwest university that participated in this study. Greater WSC was associated with decreased job satisfaction and increased negative affect (NA). Social support buffered the relationship between WSC and job satisfaction such that individuals with low social support experienced a decrease in job satisfaction when WSC was high, but they did not experience this decrease with social support was high. Greater social support from co-workers was associated with increased job satisfaction and …

The Writer-Of-Violence-As-School-Shooter Stereotype: How Columbine, Virginia Tech, And Public Fear Make Writing Violence Dangerous For Students, Matt Foy

Dissertations and Theses @ UNI

In a period when students, parents, teachers and administrators are bombarded with images related to school shooting attacks, efforts to prevent such attacks in the future and to identify students who pose a threat to school safety have intensified. These efforts to fight the seemingly mounting wave of school violence have contributed to the rise of stereotypes of what a school shooter looks, talks, and acts like. This study examines one of these stereotypes: the writer-of-violence-as-school-shooter stereotype. This stereotype, which gained attention after 1990s rampages such as those at Heath High School (Kentucky) and Columbine High School and became highly …

Functional Stability Of Transfemoral Amputee Gait Using The 3r80 And Total Knee 2000 Prosthetic Knee Units, M. Barbara Silver-Thorn, Christine L. Glaister

Biomedical Engineering Faculty Research and Publications

Prosthetic knee designs have become extremely sophisticated compared to early constant friction single axis mechanisms. Today, prosthetists and physicians have a wide variety of components to choose from for their transfemoral amputee patients. Unfortunately, there are little quantitative data comparing the performance of different types of prosthetic components, and prosthetic prescription is often based on empirical knowledge and experience, rather than objective comparison of prosthetic designs. This study used gait analysis to objectively evaluate the stability characteristics of two types of prosthetic knee designs, the polycentric Total Knee 2000 (Ossur, Aliso Viejo, CA) and the single axis 3R80 stance control …

Predicting The Effect Of Wetland Restoration On Phosphorus Retention, Northwest Minnesota, Ryan J. Whittaker

Theses and Dissertations

Water quality in the Red River Valley and downstream in Lake Winnipeg has been diminishing due to excess nutrients from agriculture. One method to reduce nutrient loading to surface water is to create or restore wetlands in agricultural areas that drain cropped fields. It is commonly believed that wetlands improve water quality, but research has shown that restoring wetlands can actually release phosphorus (P) into solution. Reducing conditions caused by soil flooding can release Fe-bound P, since ferrous Fe is more soluble than ferric Fe. Little is known concerning how the soils in the Red River Valley will be affected …
