Don't Argue With The Members, Jaber F. Gubrium, James A. Holstein

Social and Cultural Sciences Faculty Research and Publications

Mel Pollner regularly cautioned researchers not to argue with the members of settings under consideration. He warned against substituting the researcher’s meaning for the meanings of those being studied. This article discusses facets of the caution as they relate to the research process. Seemingly simple, the tenet is nuanced in application. The article adds to the nuance by distinguishing what is called the “replacement” of meaning with the “displacement” of meaning, providing a way of understanding what members could mean if the contexts and settings of their accounts were taken into consideration.

A Novel Telecommunications-Based Approach To Mathematical Modeling Of Hiv Infection, Aaron T. Sharp

Department of Computer Electronics and Engineering: Dissertations, Theses, and Student Research

It is well known that biological systems utilize communication in some form, one prolific example of this is the propagation of HIV (Human Immunodeficiency Virus) in the human body. By modeling HIV infection as a communication system, we hope to gain a unique insight into HIV and biological communication systems in general. Such a model would provide researchers a platform for experimenting and simulating various biological communication systems. We have previously developed a layered communication protocol for interpreting biological communication systems using telecommunications paradigms and will apply said model to HIV proliferation. We will also demonstrate the effectiveness of the …

Hydrologic Evaluation Of Established Rain Gardens In Lincoln, Nebraska Using A Storm Runoff Simulator, Andrew R. Anderson

Department of Environmental Engineering: Theses and Other Student Research

Increased urbanization has resulted in water quality and flooding problems for many receiving waters in the United States. Bioretention, or rain gardens, is one of the most widely popular and effective best management practices in low impact development (LID), which strives to return a watershed to a predevelopment hydrologic regime. Many studies have evaluated large bioretention cells in research settings. There is little information on the effectiveness of homeowner-maintained rain gardens that rely on deep percolation as the method for water exfiltration. Additionally, few studies address rain garden performance in cold, arid, or semi-arid climates found in the Midwest U.S. …

Virtual Communities As Egalitarian Societies: Why Contributions Matter And What They Mean, Kristen E. Rodgers

Department of Anthropology: Theses and Student Research

This study involves a content analysis of participation and contributions within a virtual community message board. Research focuses on evaluating virtual communities as egalitarian societies and determining what benefits group members receive from participating in and contributing to these communities. Two message board virtual communities were selected for analysis using the methodological approach of netnography. Though many past studies have labeled virtual communities as egalitarian, no clear application of the social structure theory has been applied and analyzed against such a community; this study aims to fix that and identifies key components of egalitarian societies present in virtual communities. Furthermore, …

The Good Life In Psychotherapy: Implicit And Influential, Emily Lonas Morris

Theses and Dissertations

The good life, or a flourishing life, is a vision of how people ought to best live their lives. Though this vision is vital to the conduct of psychotherapy, it is generally overlooked, and thus unexamined. The therapist's vision of the good life for the client guides his or her implicit and explicit interventions. Despite this, there is relatively little discussion about this vital topic, and relatively little training into the various approaches to the good life. In this thesis, I argue that this relative lack of examination and training is due to the lack of perceived options regarding conceptions …

Optimization Of Concentrator Gaas Photovoltaic Devices With Inas Quantum Dots Through Substrate Misorientation And Electroplating, Chelsea Mackos

Theses

Optimization of InAs critical coverage is important to realizing controlled growth in quantum dot devices. Substrate misorientation can change the value of critical coverage but also creates more uniform quantum dots in both size and distribution. Uniform quantum dots are advantageous in concentrator photovoltaic devices due to increases in sub bandgap response. Concentration photovoltaic devices are designed to compete on a cost per watt basis with other terrestrial photovoltaic devices. This benefit can only be utilized if the fabrication process is also cost effective. Concentration devices rely on dense thick Au grid finger design to reduce series resistance, which can …

Corporate Philanthropy And Corporate Financial Performance: The Roles Of Social Response And Political Access, Heli Wang, Cuili Qian

Research Collection Lee Kong Chian School Of Business

Corporate philanthropy is expected to positively affect firm financial performance because it helps firms gain sociopolitical legitimacy, which enables them to elicit positive stakeholder responses and to gain political access. The positive philanthropy-performance relationship is stronger for firms with greater public visibility and for those with better past performance, as philanthropy by these firms gains more positive stakeholder responses. Firms that are not government-owned or politically well connected were shown to benefit more from philanthropy, as gaining political resources is more critical for such firms. Empirical analyses using data on Chinese firms listed on stock exchanges from 2001 to 2006 …

Social Networks And The Desire To Save Face: A Case From Singapore, Michael A. Netzley, Akanksha Rath

Research Collection Lee Kong Chian School Of Business

For five years, corporate communication undergraduates have maintained a wiki as a final course and community service project. Using Web 2.0 platforms to crowdsource and curate content, they learn to employ online communications for work purposes. When the course was launched in 2007, the dominant social media narrative invited educators to embrace a technological optimism with sub-themes of open communication, sharing, and co-creation. By 2011, student feedback had compelled the instructor to consider the limits of technological optimism and revise the course. Specifically, Singaporean students have displayed a need to save face online, which has led to a localized teaching …

A practical system implementation is also discussed in terms of an evaporative cooler design. …

Fabrication Of Grooved Hollow Fiber Membrane For Nerve Regeneration: Process Modeling And Performance Evaluation, Jun Yin

All Dissertations

Nerve injury is a general but intractable disease in traumatic injuries, leading to a significant reduction of functions in the nervous system. Extensive efforts are made on nerve injury rehabilitation. Since the appropriate connections between neurons and their targets are necessary, guiding axonal outgrowth is an essential step for neuron outgrowth in nervous system development, functioning, and regeneration. Besides the direct surgical nerve connection, an artificial means of guiding nerve regeneration called nerve conduits is widely applied in nerve injury rehabilitation. The main function of nerve conduits is to bridge the nerve gap, to help regenerating axons across damaged regions …

Electrical Coupling Between Micropatterned Cardiomyocytes And Stem Cells, Zhen Ma

All Dissertations

To understand how stem cells functionally couple with native cardiomyocytes is crucial for cell-based therapies to restore the loss of cardiomyocytes that occurs during heart infarction and other cardiac diseases. Due to the complexity of the in vivo environment, our knowledge of cell coupling is heavily dependent on cell-culture models. However, conventional in vitro studies involve undefined cell shapes and random length of cell-cell contacts in addition to the presence of multiple homotypic and heterotypic contacts between interacting cells. Thus, it has not been feasible to study electrical coupling corresponding to isolated specific types of cell contact modes.
To address …

An Examination Of Treatment Effects With A Focus On Postsecondary State Merit Aid Programs, Sherry Jensen

All Dissertations

With a focus on the impact of postsecondary merit aid programs, this body of research uses a variety of econometric methods to evaluate treatment effects. Since the introduction of Georgia's HOPE (Helping Outstanding Pupils Educationally) scholarship in 1993, a large number of U.S. states have introduced merit-based financial aid programs. As a growing emphasis is placed on higher education and an increased level of scrutiny is directed toward postsecondary charges, it is important to formally investigate the impact of such programs on the behavior of higher education institutions and students.

Using multiple state merit aid programs introduced over the period …

Automated Digital Machining For Parallel Processors, Joshua Tarbutton

All Dissertations

When a process engineer creates a tool path a number of fixed decisions are made that inevitably produce sub-optimal results. This is because it is impossible to process all of the tradeoffs before generating the tool path. The research presents a methodology to support a process engineers attempt to generate optimal tool paths by performing automated digital machining and analysis. This methodology automatically generates and evaluates tool paths based on parallel processing of digital part models and generalized cutting geometry. Digital part models are created by voxelizing STL files and the resulting digital part surfaces are obtained based on casting …

Interfacial Force Field Parameterization Using The Dual Force Field Charmm Program For The Accurate Simulation Of Peptide-Surface Interaction, Nadeem Vellore

All Dissertations

Protein adsorption to solid material surfaces is a complex phenomenon and various factors play a role in controlling these processes. Inherent limitations to understand these biological interactions using experimental approaches alone have led to the possibility of exploring these systems using computational molecular simulation methodologies. Before confidence can be placed on these computational protocols, however, rigorous validation of the applicability of these methods to accurately represent protein adsorption processes is needed. In this research, we evaluated the use of all-atom empirical force field (FF) based simulations using the CHARMM simulation program and FF for the study of peptide adsorption processes …

The Design & Implementation Of An Abstract Semantic Graph For Statement-Level Dynamic Analysis Of C++ Applications, Edward Duffy

All Dissertations

In this thesis, we describe our system, Hylian, for statement-level analysis,
both static and dynamic, of a C++ application. We begin by extending the
GNU gcc parser to generate parse trees in XML format for each of the
compilation units in a C++ application. We then provide verification that the
generated parse trees are structurally equivalent to the code in the
original C++
application. We use the generated parse trees, together with an augmented
version of the gcc test suite, to recover a grammar for the C++ dialect that
we parse. We use the recovered grammar to generate a schema …

A Statistical Approach For Shadow Detection Using Spatio-Temporal Contexts, Yiyang Liu

Graduate Theses, Dissertations, and Problem Reports (ETD)

Background subtraction is an important step used to segment moving regions in surveillance videos. However, cast shadows are often falsely labeled as foreground objects, which may severely degrade the accuracy of object localization and detection. Effective shadow detection is necessary for accurate foreground segmentation, especially for outdoor scenes. Based on the characteristics of shadows, such as luminance reduction, chromaticity consistency and texture consistency, we introduce a nonparametric framework for modeling surface behavior under cast shadows. To each pixel, we assign a potential shadow value with a confidence weight, indicating the probability that the pixel location is an actual shadow point. …

Mechanical Property Evaluation Of Torrefied Biomass Materials With Correlation To Grinding Efficiency, Xin Zhou

Graduate Theses, Dissertations, and Problem Reports (ETD)

Motivated by the transition to a more sustainable society, biomass, currently the largest renewable energy source in the world, could therefore in principle become a key energy source in the future. Co-combustion of these materials and coal can lead to a significant reduction in carbon dioxide net emissions in new and existing power plants while potentially reducing capture costs as well. However, many challenges remain to be solved before biomass can be used on a much larger scale as a sustainable energy source. Some of these challenges are related to biomass production, land management, and competition with food production; but …

Experimental Analysis Of The Post-Failure Behavior Of Coal And Rock Under Laboratory Compression Tests, Dachao Neil Nie

Graduate Theses, Dissertations, and Problem Reports (ETD)

A major aspect of coal mine design is the structural stability of the mine. For establishing structural stability, the strength of the strata is determined by recovering the cores. The strength is determined through various methods and one method in particular is the Uniaxial Compressive Strength of the rock, which is commonly adopted as the standard strength indicator. However, in-situ behavior by past researchers have shown that rock and coal show significant residual strength contrary to the failure path observed in a conventional compression tests. Researchers in past had used stiff system for generating the post failure behavior of the …

Bioelectrical Impedance Analysis Methods For Prediction Of Brook Trout Salvelinus Fontinalis Percent Dry Weight, Andrew William Hafs

Graduate Theses, Dissertations, and Problem Reports (ETD)

Reliable fish condition estimates are valued by fisheries ecologists and managers. Fish condition is used as an indicator of ecosystem health or to assess the population status for a species of interest. In aquaculture, proximate composition estimates are often wanted because of their relationship to fillet quality. Past researchers have used bioelectrical impedance analysis (BIA) to provide nonlethal mass based estimates of proximate composition for fish. Percent dry weight (PDW) of a fish is highly correlated to proximate composition values and energy density, therefore reliable predictions of PDW would eliminate the need for costly and laboratory analyses lethal to the …
