Making Sense Of Technology Trends In The Information Technology Landscape, Gediminas Adomavicius, Jesse C. Bockstedt, Alok Gupta, Robert J. Kauffman

Research Collection School Of Computing and Information Systems

A major problem for firms making information technology investment decisions is predicting and understanding the effects of future technological developments on the value of present technologies. Failure to adequately address this problem can result in wasted organization resources in acquiring, developing, managing, and training employees in the use of technologies that are short-lived and fail to produce adequate return on investment. The sheer number of available technologies and the complex set of relationships among them make IT landscape analysis extremely challenging. Most IT-consuming firms rely on third parties and suppliers for strategic recommendations on IT investments, which can lead to …

Of Muslim Persuasion: The Politics Of Convivencia In Ceuta, Spain, Gabriel Alejandro Torres Colón

Anthropology ETDs

This dissertation examines everyday interactions and political struggles between self-identified Christians and Muslims in the North African Spanish exclave of Ceuta. I explore how each group envisions themselves as part of a local and national community, and then I consider how such visions affect local political processes in everyday life and institutional politics. This dissertation brings a political anthropological perspective to the study of multiculturalism and presents a theoretical perspective for the study of difference in various political contexts.

Cognitive Development And The Understanding Of Informed Consent, Lindsey Elizabeth Pearse

Masters Theses and Doctoral Dissertations

The informed consent process is an important criterion for all research studies. However, researchers rarely ask or even consider how many participants truly understand the informed consent information and their research rights. Currently, researchers base a participant’s ability to understand informed consent information and research rights on age. In the present study it was hypothesized that cognitive development is a predictor of ethical knowledge. Accordingly, it was argue d that a participant’s ability to understand informed consent and research rights should not be based on a participant’s age but instead on the participant’s cognitive development. Students at the University of …

Cultural Scenarios Of The Fantastic, Asunción López-Varela

CLCWeb: Comparative Literature and Culture

In her article, "Cultural Scenarios of the Fantastic," Asunción López-Varela Azcárate explores the relationship between technological development, the materiality of objects, the concept of ontological presence, and the emergence of abstract and fantastic models. López-Varela Azcárate argues that since the early twentieth century there has been a return to the fantastic in literature and that this is related to neo-baroque attitudes whose foundations are a systemic way of knowing that unveils a world understandable from an epistemology of complexity and ambiguity. In postmodern neo-baroque aesthetics, with its focus on technological re-mediating, that is, transferring information across different media, originality is …

Death And Love In Poe's And Schwob's Readings Of The Classics, Ana González-Rivas Fernández, Francisco García Jurado

CLCWeb: Comparative Literature and Culture

In their article "Death and Love in Poe's and Schwob's Readings of the Classics," Ana González-Rivas Fernández and Francisco García Jurado propose that although Gothic literature usually relegates the theme of love to the background, devoting most of its attention to the supernatural and to darkness, there are also literary texts in which love is mixed with life beyond the grave. This is the case, for example, of Théophile Gautier's La Morte amoureuse (1836), the story of a vampire who comes back to life in her "undead" condition in order to seduce a priest. The theme of love and death …

Metamorphosing Worlds In The Cinema Of The Fantastic, Juan González Etxeberria

CLCWeb: Comparative Literature and Culture

In his article "Metamorphosing Worlds in the Cinema of the Fantastic" Juan González Etxeberria reads fantastic films as appealing products of both unconscious psychological and institutionalized sociological anxieties. A result of the binary opposition of rhetorical strategies that shaped modern culture, the genre is an open door to other worlds where to dream of uncertainties and to indulge in our traumas. Its transgressive indeterminacy against the Cartesian system is traced from the origin of creative filmic language to postmodern disturbing fantasies about the unknown, having social control and individual free will as the only limits of its imaginary trips across …

Modeling, Analysis And Control Of Flexible Solid-State Hysteretic Actuators, Kushan Vora

All Theses

A distributed parameters modeling and control framework for flexible solid-state hysteretic actuator is presented in this work. For the simplicity of analysis, the actuator dynamic behavior is decoupled and treated separately from the hysteresis nonlinearity. To include the effects of widely-used flexural mechanisms, a mass-spring-damper boundary condition is considered for system. Moreover, the effect of electromechanical actuation is included as a concentrate force at the boundary. The problem is then divided into two parts: first part deals with free motion analysis of system in order to obtain eigenvalues and eigenfunctions using the expansion theorem and a standard eigenvalue problem procedure. …

Tolerance Intervals In Random-Effects Models, Kakotan Sanogo

Theses and Dissertations

In the pharmaceutical setting, it is often necessary to establish the shelf life of a drug product and sometimes suitable to assess the risk of product failure at the desired expiry period. The current statistical methodology use confidence intervals for the predicted mean to establish the expiry period and prediction intervals for a predicted new assay value or a tolerance interval for a proportion of the population for use in a risk assessment. A major concern is that most methodology treat a homogeneous subpopulation, say batch, either as a fixed effect and therefore uses a fixed-effects regression model (Graybill, 1976) …

Self-Medicative Behavior Of Sheep Experiencing Gastrointestinal Nematode Infections And The Postingestive Effects Of Tannin, Larry D. Lisonbee

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Diet selection and self-medication are fundamental to the survival of all species. The abilities to choose healthy foods in response to past consequences are basic elements of evolution. This study explores self-medication regarding tannins both as a medication and as a dietary challenge. In the first study, sheep with natural parasite infections were offered a low quality supplement containing a dose of tannins considered to be therapeutic (medicine), while the control infected lambs received the same supplement without tannins (placebo). This study included a group of parasite-free lambs. The parasitized lambs ate more of the tannin containing supplement than non-parasitized …

'Fabrication And Characterization Of Polymer Blends And Composites Derived From Biopolymers', Suraj Sharma

All Dissertations

This research focuses on fabricating blends and composites from natural polymers especially from proteins and natural epoxy, and describing the properties of plastics made from them. Specifically, plastic samples from partially denatured feathermeal and bloodmeal proteins, derived from the animal co-products (rendering) industry, were successfully produced through a compression molding process. The modulus (stiffness) of the material obtained was found to be comparable with that of commercial synthetic materials, such as polystyrene, but was found to have lower toughness characteristics, which is a common phenomenon among plastics produced from animal and plant proteins. Therefore, this study explored blending methods for …

Human Microvasculature Fabrication Using Thermal Inkjet Printing Technology, Xiaofeng Cui

All Dissertations

The current tissue engineering paradigm is that successfully engineered thick tissues must include vasculature. As biological approaches alone such as VGEF have fallen short of their promises, one may look for an engineering approach to build microvasculature. With the advent of cell printing, one may be able to build precise human microvasculature with suitable bio-ink. Human Microvascular Endothelial Cells (HMVEC) and fibrin were studied as bio-ink for microvasculature construction. Endothelial cells are the only cells to compose the human capillaries and also the major cells of blood vessel intima layer. Fibrin has been already widely recognized as tissue engineering scaffold …

Optimization Of Biodiesel Production From Crude Cottonseed Oil And Waste Vegetable Oil:Conventional And Ultrasonic Irradiation Methods, Xiaohu Fan

All Dissertations

Biodiesel, derived from the transesterification of vegetable oils or animal fats with simple alcohols, has attracted more and more attention recently. As a cleaner burning diesel alternative, biodiesel has many attractive features including: biodegradability, nontoxicity, renewability and low emission profiles.
Although cottonseed oil was the first commercial cooking oil in the U.S, it has progressively lost its market share to some vegetable oils that have larger production and less cost. However, regarding the active researches on biodiesel production from vegetable oils, there is a promising prospective for the cottonseed oil as a feedstock for biodiesel production, which may enhance the …

Institutional Culture, Performance, And Learning In A Two-Year Technical/Community College, Vicky Maloney

All Dissertations

The environments of higher education institutions have undergone significant changes in the past twenty years as a result of concerns expressed in prominent reports. These external concerns and initiatives reflect contemporary criticisms by the public about the efficiency and effectiveness of the performance of institutions. The response from research, legislatures, and the institutions has been to implement practices aimed at improvement and borrowed from business and industry. Research indicates that this performance orientation to change in higher education has largely failed, due in part to the lack of attention given to the culture of the institution.
Emerging research indicates a …

Theoretical And Practical Implications Of A Hedonic Pricing Model: Empirical Observations From Wholesale Automobile Auctions, Jeffrey Roach

All Dissertations

Wholesale auto auctions are convenient structures for economists as they attempt to observe the marginal effects of quality changes on the market-clearing price. However, what may be categorized as a quality change might rather be a market signal of an environment with adverse selection. This dissertation analyzes the effects of seller type and tests their sensitivity to econometric model specification.
General hedonic attributes and their various applications are reviewed. This dissertation explores the basic auto auction environment and dispels inaccurate notions about the auction structure. Following Bartik's (1987) analysis, multi-market data are used to produce hedonic estimates for seller, mileage …

Electrical and Computer Engineering Faculty Research and Publications

The benefits and drawbacks of a 5-hp reconfigurable induction motor, which was designed for experimental emulation of stator winding interturn and broken rotor bar faults, are presented in this paper. It was perceived that this motor had the potential of quick and easy reconfiguration to produce the desired stator and rotor faults in a variety of different fault combinations. Hence, this motor was anticipated to make a useful test bed for evaluation of the efficacy of existing and new motor fault diagnostics techniques and not the study of insulation failure mechanisms. Accordingly, it was anticipated that this reconfigurable motor would …

Dependence Of The Performance Of Single Photon Avalanche Diodes On The Multiplication Region Width, David A. Ramirez, Majeed M. Hayat, Mark A. Itzler

Electrical and Computer Engineering Faculty Research and Publications

The dependence of the performance of separate-absorption-multiplication (SAM) single-photon avalanche diodes (SPADs) on the width of the multiplication region is theoretically investigated. The theory is applied to SAM SPADs with InP homojunction multiplication regions and InAlAs-InP heterojunction multiplication regions. In both cases the absorber layer is InGaAs. Two scenarios for the dark counts are considered: (i) low-temperature operation, when the number of dark carriers is dominated by field-assisted mechanisms of band-to-band tunneling and tunneling through defects; and (ii) room-temperature operation, when the number of dark carriers in the multiplication region is dominated by the generation/recombination mechanism. The analysis utilizes a …

Functional Characterization Of Hexokinase-Like 1 (Hkl1) From Arabidopsis Thaliana, Abhijit Karve

All Dissertations

Arabidopsis hexokinase1 (AtHXK1) is a moonlighting protein with roles in both glucose signaling and catalysis. In this study, we first cloned and characterized the six HXK related genes from Arabidopsis. Three of the six encoded proteins were shown not to phosphorylate hexoses and thus, are designated as hexokinase-like (HKL) proteins. Though they are only 50% identical to HXK1, the amino acid sequences of HKL1 and HKL2 both have well conserved glucose binding domains and other recognized structural elements. The possible basis for their lack of catalytic activity was further probed by site-directed mutagenesis and ultimately was attributed to a suite …
