A Cultural Contingency Leadership Model For A Multinational Higher Education Joint Venture, Frankie Albritton Jan 2007

A Cultural Contingency Leadership Model For A Multinational Higher Education Joint Venture, Frankie Albritton

Electronic Theses and Dissertations

This dissertation addressed the need for empirical research on the leadership of multinational virtual teams (Davis & Bryant, 2003; Early & Gibson, 2002; Ilgen, Lepine, and Hollenbeck, 1997; Prieto & Arias, 1997), particularly in the field of educational leadership (Cheng, 1995). This was accomplished through the development of a model based upon the cultural values discovered through the use of Hofstede's (1980, 2001) Values Survey Module 94 (VSM 94). As workers will bring values from their own cultures to the multinational workplace (Bochner & Hesketh, 1994), research was conducted to determine the cultural values of economics professors in the United …

Resiliency In Adolescent College Students, Nancy Ahern Jan 2007

Resiliency In Adolescent College Students, Nancy Ahern

Electronic Theses and Dissertations

The construct of resilience has gained considerable attention over the last four decades since researchers observed that children and youth could cope and adapt in spite of adversity. Resilience involves a dynamic process involving an interaction between both risk and protective processes, internal and external to the individual, that can modify the effects of an adverse life event. Adolescence is considered to be a period of vulnerability for most individuals as they often partake in high risk behaviors. Further, those individuals who are in their early college years are faced with the developmental challenges of this life phase which can …

Verification Of Pilot-Scale Iron Release Models, Stephen Glatthorn Jan 2007

Verification Of Pilot-Scale Iron Release Models, Stephen Glatthorn

Electronic Theses and Dissertations

A model for the prediction of color release from a pilot distribution system was created in 2003 by Imran. This model allows prediction of the release of color from aged cast iron and galvanized steel pipes as a function of water quality and hydraulic residence time. Color was used as a surrogate measurement for iron, which exhibited a strong linear correlation. An anomaly of this model was an absence of a term to account for pH, due to the influent water being well stabilized. A new study was completed to evaluate the effectiveness of corrosion inhibitors against traditional adjustment. Two …

Identification And Suitability Of A Non-Anthropomorphic Meta-Language Framework In Military Applications, Gilbert Cardona Jan 2007

Identification And Suitability Of A Non-Anthropomorphic Meta-Language Framework In Military Applications, Gilbert Cardona

Electronic Theses and Dissertations

Humans carry mental models concerning the behaviors, looks, and operation of products, tools, and items used in their daily lives. When these items do not fit a user's conceptual model confusion and inefficiency occur. There are four basic types of mental models based on interactive activities: 1) instructing, 2) conversing, 3) manipulating and navigating, and 4) exploring and browsing. This thesis will focus on the conversing conceptual model and its application to communications between human-agent teams to best fit a user's mental model for that communication. A non-anthropomorphic framework does not exist for use in military applications such as; target …

Synthesis Of Novel Aziridine Derivatives Of Podocarpic Acid, Stephen Rhoden Jan 2007

Synthesis Of Novel Aziridine Derivatives Of Podocarpic Acid, Stephen Rhoden

Electronic Theses and Dissertations

Podocarpic acid (a diterpenoid resin acid extracted from the Podocarpacea specie of plants) has shown cytotoxicity against carcinoma of the nasopharynx. Since this discovery has been made, research has been performed in order to alter the structure of the resin acid so as to increase the anticancer activity. The carboxylic acid and phenol functional groups, which are present in podocarpic acid, make it possible to synthesize new derivatives selectively at the C-15, C-13, and C-7 positions as well as by substitution of the phenol hydroxyl group. Thus numerous derivatives can be prepared, in high yield, for the purpose of investigating …

Signal Processing Of An Ecg Signal In The Presence Of A Strong Static Magnetic Field, Aditya Gupta Jan 2007

Signal Processing Of An Ecg Signal In The Presence Of A Strong Static Magnetic Field, Aditya Gupta

Electronic Theses and Dissertations

This dissertation addresses the problem of elevation of the T wave of an electrocardiogram (ECG) signal in the magnetic resonance imaging (MRI). In the MRI, due to the strong static magnetic field the interaction of the blood flow with this strong magnetic field induces a voltage in the body. This voltage appears as a superimposition at the locus of the T wave of the ECG signal. This looses important information required by the doctors to interpret the ST segment of the ECG and detect diseases such as myocardial infarction.

Fate Of Nitrogen And Phosphorus Species From A Black And Goldtm Nugget Mix In A Laboratoy Column Simulated Septic Tank Drainfiel, Timir Shah Jan 2007

Fate Of Nitrogen And Phosphorus Species From A Black And Goldtm Nugget Mix In A Laboratoy Column Simulated Septic Tank Drainfiel, Timir Shah

Electronic Theses and Dissertations

The presence of nitrates and phosphorus in ground water is a worldwide problem. A septic tank with drainfield that is conventionally designed does not typically remove nitrogen in the form of nitrates. The main risks are in "Blue baby" syndrome and suspected carcinogenic effect of nitrates on humans and the nutrient enrichment of receiving waters. In some areas nitrate and phosphorus removal are essentially required. Thus the information in this report concentrates on using media in the drainfield for the removal of nitrogen and phosphorus. Extensive work has been conducted in the past few decades in order to find suitable …

An Economic Framework For Resource Management And Pricing In Wireless Networks With Competitive Service Providers, Shamik Sengupta Jan 2007

An Economic Framework For Resource Management And Pricing In Wireless Networks With Competitive Service Providers, Shamik Sengupta

Electronic Theses and Dissertations

A paradigm shift from static spectrum allocation to dynamic spectrum access (DSA) is becoming a reality due to the recent advances in cognitive radio, wide band spectrum sensing, and network aware real--time spectrum access. It is believed that DSA will allow wireless service providers (WSPs) the opportunity to dynamically access spectrum bands as and when they need it. Moreover, due to the presence of multiple WSPs in a region, it is anticipated that dynamic service pricing would be offered that will allow the end-users to move from long-term service contracts to more flexible short-term service models. In this research, we …

Behavior Of Variable-Length Genetic Algorithms Under Random Selection, Harold Stringer Jan 2007

Behavior Of Variable-Length Genetic Algorithms Under Random Selection, Harold Stringer

Electronic Theses and Dissertations

In this work, we show how a variable-length genetic algorithm naturally evolves populations whose mean chromosome length grows shorter over time. A reduction in chromosome length occurs when selection is absent from the GA. Specifically, we divide the mating space into five distinct areas and provide a probabilistic and empirical analysis of the ability of matings in each area to produce children whose size is shorter than the parent generation's average size. Diversity of size within a GA's population is shown to be a necessary condition for a reduction in mean chromosome length to take place. We show how a …

Individual Identification Of Polar Bears By Whisker Spot Patterns, Carlos Anderson Jan 2007

Individual Identification Of Polar Bears By Whisker Spot Patterns, Carlos Anderson

Electronic Theses and Dissertations

Many types of ecological studies require identification of individual animals. I developed and evaluated an automated identification system for polar bears (Ursus maritimus) based on their whisker spot patterns. First, I measured the reliability of using whisker spot patterns for identification from polar bear photographs taken in western Hudson Bay. This analysis involved estimating the complexity of each whisker spot pattern in terms of its information content. I found that 98% of patterns contained enough information to be reliable, and this result varied little among three different observers. Based on these results, I implemented a computer-aided identification system for polar …

Vacancy Engineered Doped And Undoped Nanocrystalline Rare Earth Oxide Particles For High Temperature Oxidation Resistant Coating, Ranjith Thanneeru

Electronic Theses and Dissertations

Rare earth oxides with trivalent lattice dopants have been of great interest to researchers in the recent years due to its potential applications in catalysis and high temperature protective coatings. The ability to store oxygen in rare earths is the basis for catalysis because of the ability to change valence states which causes the presence of intrinsic oxygen vacancies in the crystal lattice. Although, several doped-rare earth oxide systems in micron scale have been investigated, the doping effect in cerium oxide nanoparticles with well characterized particle size has not been studied. The doping of ceria at that small size can …

Adaptive Technomythography: The Apotheosis Of Machine And Development Of Legend In A System Of Dynamic Technology, Roger Wolf

Electronic Theses and Dissertations

Human beings will effectively deify any suitably complex system that cannot be explained through basic haptic interaction. Our culture loves technology. These days it seems we need it to feel whole. In an effort to explore the development of mythology and modular aesthetic in a technological age I have designed and constructed a number of interactive robotic 'organisms' to engage in arbitrary movement in geometric enclosures. Through observation and dialog I seek to assess the extent to which people assign human characteristics to the random and oft times aberrant mechanical behavior. To supplement this endeavor, a fictional astrological system that …

Spatiotemporal Variation Of Avian Populations Within Geographically Isolated Freshwater Marshes, Brian Rodenbeck Jan 2007

Spatiotemporal Variation Of Avian Populations Within Geographically Isolated Freshwater Marshes, Brian Rodenbeck

Electronic Theses and Dissertations

Metacommunity connectivity, i.e., multi-species dispersal events, is vital to metapopulation persistence in patchy landscapes. Assessments of metacommunity connectivity are not trivial. However, a relationship between trophic rank and the species-area relationship has been found in previous studies, allowing for the use of the predator species-area relationship to act as a surrogate measure of actual metacommunity connectivity of prey species in some systems. For this study, avian species were selected as they are generalist top predators within the study system. Predator species richness within geographically isolated freshwater marshes is influenced by a number of factors. I explore the relative roles of …

Effect Of Coyotes And Release Site Selection On Survival And Movement Of Translocated Swift Foxes In The Badlands Ecosystem Of South Dakota, Greg M. Schroeder Jan 2007

Effect Of Coyotes And Release Site Selection On Survival And Movement Of Translocated Swift Foxes In The Badlands Ecosystem Of South Dakota, Greg M. Schroeder

Electronic Theses and Dissertations

Success of different release strategies for swift fox (Vulpes velox) translocation was evaluated in the Badlands Ecosystem in southwestern South Dakota. Release site selection (outside coyote [Canis latrans] core-use areas compared to random release sites) and release method (i.e., hard, semi-hard, and soft) were examined to determine effects on swift fox survival and movements at 50 days post-release. I hypothesized that swift foxes released outside of coyote core-use areas would survive at a higher rate than foxes released at random sites. From 2003-2006, 16 adult coyotes were fitted with Global Positioning System (GPS) radio collars and monitored during the pup …

Another Look At Gender In Prime-Time Television, Jan Carolyn Kircher Jan 2007

Another Look At Gender In Prime-Time Television, Jan Carolyn Kircher

Electronic Theses and Dissertations

Television has become an important agent of socialization in society today. Social interaction on prime-time television was examined 24 years ago by members of the Sociology Department at South Dakota State University. That study was similar to this research project that investigates gender roles on prime-time television. The earlier study used a modified version of the Bales Interaction Scale to code male and female behavior to assess the extent to which prime-time television presented traditional or nontraditional gender roles. This study used research methods similar to those of the previous study to see if traditional gender roles depicted on prime-time …

Status, Distribution, And Density Of White-Tailed Jackrabbits And Black-Tailed Jackrabbits In South Dakota, Dustin J. Schaible

Electronic Theses and Dissertations

The status of jackrabbit (Lepus spp.) populations throughout the Northern Great Plains has been a cause for concern by wildlife managers in recent years and there has been a paucity of information about the ecology of the white-tailed jackrabbit (Lepus townsendii) and the black-tailed jackrabbit (Lepus californicus) in South Dakota. Since there have been little monitoring efforts for hares, 21 permanent spotlight line transects were established across South Dakota for future surveying efforts. These transects were surveyed to obtain baseline information about jackrabbit density and distribution throughout the state. Jackrabbit density was highest in the northwestern portions of the state …
