In the second phase, qualitative interviews were used to …

Theology Of Judgment In Genesis 6-9, Chun Sik Park

Dissertations

The present dissertation seeks to develop a theology of judgment in Gen 6-9. Following an introductory chapter, the second chapter is devoted to analyzing the three main extrabiblical ANE flood stories (the Eridu Genesis, the Atra-Hasis Epic, and the Gilgamesh Epic) from the four aspects of judgment: date, cause and purpose, extent, and procedure. The analysis of those stories reveals that the ANE flood was a historical and local (global dimension is implied) event without moral cause, and that the judgment of the deities had a procedure of investigation, sentence, execution, and mitigation. The third chapter treats the theology of …

The Student Missionary Experience And Its Impact On Young Adults, Troy Fitzgerald

Dissertations

Problem. While reputed to be valuable, the Student Missionary (SM) experience has not been studied to ascertain how a year of service impacts the college students who serve. Furthermore, there are no studies that show what aspects of the SM experience make a year of service transformational. Most of what is known about a year of service is anecdotal and begs for systematic study of the SM experience.

Method. This is primarily a qualitative study where former SMs from four Adventist colleges and universities were interviewed. The Christian Spiritual Participation Profile (CSPP) was administered to SMs as an …

Proclamation In Cross-Cultural Context: Missiological Implications Of The Book Of Daniel, Sung Ik Kim

Dissertations

This study attempts to explore the biblical foundation ofsalvific mission as revealed in God's purposes for the nations (missio Dei ) in the book of Daniel and to investigate the means that Daniel employed in his ministry as an overt missionary who was sent to witness to God's salvific purpose in the cross-cultural context of heathen kingdoms.

The main objective of this research is to validate the book of Daniel as a missionary document and show that its missiological implications are still relevant to present-day missions. Chapter 2 explores the salvific purpose of missio Dei in the book of …

Effects Of Nicotine And Anatoxin-A Exposures On The Operant Performance Of Rats, Kimberly Ann Jarema

Dissertations

Tolerance has previously been shown to develop to nicotine's effects on operant behavior. This experiment explored whether tolerance would still develop when nicotine administrations were separated by three weeks. Anatoxin-a, a nicotinic-receptor agonist, was also tested and the results were compared to nicotine. Male Long Evans rats performed under a multiple VR30 VI30-sec food-reinforcement schedule. Phase I rats were divided into 6 groups of 8 that received four weekly subcutaneous injections of nicotine (0.0-1.8 mg/kg) and anatoxin-a (0-250 mcg/kg) prior to testing sessions. An ED50 was derived, for each compound, from the VR dose-response curve. Phase II rats were divided …

Assessing The Differential Outcomes Procedure With Children Diagnosed With Autism, Ivy M. Chong

Dissertations

The differential outcomes effect (DOE) refers to the phenomenon whereby discrimination learning is enhanced when a correct response to a specific sample stimulus is followed by its own unique reward (Savage, 2001). According to some researchers, the DOE is a consistent and powerful effect that enhances the acquisition and retention of conditional discriminations (e.g., Urcuioli, 1990). This series of experiments sought to extend research on the DOE. In Experiment 1, we examined the differential outcomes procedure (DOP) with four children diagnosed with autism across various task types commonly used in early intervention. In Experiment 2, we examined the DOP with …

Investment And Capital Flows Under Uncertainty And Capital Market Imperfection In Oil Producing Countries, Mohamed Gaber Hassan Elsayed

Dissertations

This dissertation analyzes and estimates the interactions between domestic investment and each type of capital flow under uncertainty and capital market imperfection in 13 oil-producing countries from 1981 to 2003. First, we discuss the recent development in investment theories under uncertainty, irreversibility, and imperfect capital market. Secondly, decomposing uncertainty into permanent and transitory components--based on C-GARCH--we constructuncertainty measures of broad macroeconomic variables in addition to oil price.

Thirdly, a model of four simultaneous equations is developed to capture dynamic interactions. My contribution is twofold. First, not only do we consider the impact of uncertainty and credit market imperfection on investment, …

Divine Minds: The Cognitive Foundations Of God And Religion, Todd Tremlin

Dissertations

Understanding how human brains work bears directly on the study of religion. Introducing the new "cognitive science of religion," this dissertation explains how natural mental processes that shape everyday human thought are also responsible for the arising and persistence of religious ideas and for the content and development of religions. The central claim of this work is that understanding the origin and features of god concepts and the religious systems that form around them requires an understanding of the adapted mind. This argument unfolds in two parts. The first explores the cognitive foundations ofsupernatural beings. It discusses in both evolutionary …

Pitchfork Bifurcations Of Invariant Manifolds, Jyoti Champanerkar

Dissertations

In a parameter dependent, dynamical system, when the qualitative structure of the solutions changes due to a small change in the parameter, the system is said to have undergone a bifurcation. Bifurcations have been classified on the basis of the topological properties of fixed points and invariant manifolds of dynamical systems. A pitchfork bifurcation in R is said to have occurred when a stable fixed point becomes unstable and two new stable fixed points, separated by the unstable fixed point come into existence.

In this thesis, a pitchfork bifurcation of an (in- 1)-dimensional invariant submani-fold of a dynamical system in …

Modeling Contaminant Transport And Fate And Subsequent Impacts On Ecosystems, Ming Fan

Dissertations

Assessing risks associated with the release of metals into the environment and managing remedial activities requires simulation tools that depict speciation and risk with accurate mechanistic models and well-defined transport parameters. Such tools need to address the following processes: (1) aqueous speciation, (2) distribution mechanisms, (3) transport, and (4) ecological risk. The primary objective of this research is to develop a simulation tool that accounts for these processes. Speciation in the aqueous phase can be assessed with geochemical equilibrium models, such as MINEQL+. Furthermore, metal distribution can be addressed mechanistically. Studies with Pb sorption to amorphous aluminum (HAG), iron (HFO), …

Toxicity Of Manufactured Particulate Materials On Plant Root Growth, Ling Yang

Dissertations

The rapid development of particle technology and the growing use of particulate materials in industries are bringing large amounts of manufactured particles into the environment. Epidemiological studies suggest that fine particles (particles with aerodynamic diameter smaller than 2.5 μm, i.e., PM_2.5) have an association with various adverse health effects in humans. Mass studies have been performed on the toxicity and toxicological mechanisms of airborne particles such as PM_2.5 and PM₁₀, but there are very few investigations which contribute to the knowledge base on biological implications of manufactured particulate materials. Up to now, the published toxicity …

From Violence-Prone To Violence-Prepared Organizations Assessing The Role Of Human Resources Management In Preventing Workplace Violence In American City Governments, Saleh Abdel Rahman Ahmed

Dissertations

Violence is a significant occupational hazard in the American workplace. Nearly a thousand employees are murdered on the job each year and workplacehomicide has become the leading cause of death for women and the second for men. From 1993 to 1999, there were an average of 1.7 million nonfatal violent victimizations each year, accounting for 18% of all violent crime. Although government employees accounted for 18% of the U.S. workforce, they made up 37% of workplace violence victims.

A review of literature found no unified definition of workplace violence. Recent scientific research regarding this problem is rare, despite its increasing …

Dear Beyond, Kirsten Hemmy

Dissertations

My project. Dear Beyond, a collection of poetry, examines the connection between landscape—both internal and external, or private and public—and environment. My poetry reflects my own unique background and my struggles with emplacement, or the placing of oneself in any particular landscape. It aims to challenge dominant paradigms of voice, expression, and even inquiry; it questions traditional, systematic forms of inquiry such as the Cartesian idea of an essential separation between object and subject. Culture and landscape, I have discovered, manifest themselves everywhere, in variegated forms: in spaciousness or intimacy, in internal and external contexts, in tactile experiences, in focused …

The purpose of the current study was to assess whether children would categorize pictures when taught the relevant listener and speaker behaviors separately. A category-sort test was used to assess emergent conditional relations. Category-sort trials consisted of looking at (Test 1) or tacting/labeling (Test 2) a samplestimulus and selecting the appropriate comparison stimuli. In Experiment 1, 4 children (3- 5 years) were taught to tact pictures of six U.S. state maps as either north or south. An assessment was conducted to determine whether they would (1) correctly categorize or sort when presented with a visual sample and (2) select the …

Differentiation Of The Causal Characteristics And Influences Of Virtual Reality And The Effects On Learning At A Science Exhibit, Arlene De Strulle Edd

Dissertations

Within the context of the informal science center, exhibits are the main interface for public learning. Essential to the success of a science center is how well exhibits model effective strategies for learning. Virtual Reality (VR) technology with its flexible, adaptive, multimedia, and immersive-learning capabilities is emerging for use by science centers in exhibits; however, research on learning in virtual environments at exhibits is scarce. To support the future development of VR science exhibits it is critical to investigate VR's pedagogical value and effects on science learning. Research investigated the Smoke & Mirrors VR exhibit at the Reuben H. Fleet …

The Social Construction Of Rape Research: Exploring Epistemologies And Evaluating Methods, Edith M. Fisher

Dissertations

The most widely known national study of rape found that one in four college-age women has been the victim of rape or attempted rape. Conservative writers have criticized that study for overestimating the possible prevalence of rape in the U.S. My research uses more sensitive instruments and administration techniques, seeking to estimate the prevalence of rape in the lives of women at a large midwestern public university. I address questions about the validity of previous rape research and compare methods of collecting sexual violence information by questionnaire (322 mailed surveys and 300 interviewer-administered surveys). Additional interviews with 62 of the …

The Interactions Between An Orthodox Christian Worldview And Environmental Attitudes And Beliefs; For The Purpose Of Developing Better Instructional Practice In Support Of Environmental/Ecological Attitudes And Knowledge, Robert S. Keys

Dissertations

Students bring with them to the classroom a wide variety of beliefs and attitudes about the environment and its associated issues. One worldview belief structure prominently discussed in ecological discussions is the worldview of orthodox Christianity. This study uses both quantitative and qualitative measures to analyze the degree to which the orthodox Christian worldview of students influences their environmental attitudes and beliefs. Surveys were conducted with 281 undergraduate pre-service elementary teaching students enrolled in a science methods course to determine the degree to which orthodox Christian worldviews and ecological worldviews interact with one another. From this pool of students, 16 …

Child Welfare And Devolving Federalism: An Analysis Of The Effects Of Federal Funding Schemes On Selected Child Welfare Outcomes In Michigan, Timothy J. Kangas

Dissertations

Child abuse and neglect has become a pervasive problem across the United States. Between 1985 and 1995 the foster care population in the United States grew by 79%, with costs soaring into the billions. During the mid-1990s, in an effort to address this issue, the federal government shifted from using a funding scheme identified with a traditional model of federalism to one identified with devolving federalism. In Michigan, the focus of this research, this shift in approaches occurred through the issuance of block grant funding for child welfare programming. The intent of this shift was to decentralize elements of the …

Statistical Anomaly Denial Of Service And Reconnaissance Intrusion Detection, Zheng Zhang

Dissertations

This dissertation presents the architecture, methods and results of the Hierarchical Intrusion Detection Engine (HIDE) and the Reconnaissance Intrusion Detection System (RIDS); the former is denial-of-service (DoS) attack detector while the latter is a scan and probe (P&S) reconnaissance detector; both are statistical anomaly systems.

The HIDE is a packet-oriented, observation-window using, hierarchical, multi-tier, anomaly based network intrusion detection system, which monitors several network traffic parameters simultaneously, constructs a 64-bin probability density function (PDF) for each, statistically compares it to a reference PDF of normal behavior using a similarity metric, then combines the results into an anomaly status vector that …

Uncertainty Analysis In Ecological Risk Assessment Modeling, Tepwitoon Thongsri

Dissertations

A probabilistic approach employing Monte Carlo simulations for assessing parameter and risks as probabilistic distributions was used in an ecological risk assessment (ERA) model to characterize risk and address uncertainty. This study addresses the following sources of uncertainty: parameter inputs in the ERA models, risk algorithms and uncertain input concentrations. To achieve this objective, both sensitivity and uncertainty analyses are being conducted. Monte Carlo simulations were used for generating probabilistic distributions of parameter and model uncertainty. All sensitivity, uncertainty, and variability analyses were coded in Visual Basic as part of the ERA model software version 2001, which was developed under …

Organizational Structure And The Creative Process, Edward C. Bowen Edd

Dissertations

A creative edge can be a powerful source of competitive advantage in business, in war, in the arts, in science, and in life. In fact, creativity, innovation and the ability to adapt and change organizational structures in response to an increasingly fast-paced and competitive business environment are increasingly seen as essential for the success of many organizations. A current trend in organizational theory associates increases in formalization and both horizontal and vertical integration with decreases in an organization's ability to innovate and adapt. Consequently, organizational change efforts often involve moving from traditional, hierarchical structures toward flatter, more flexible types of …

Health Impacts Of Polychlorinated Biphenyls (Pcbs) In Aquatic Organisms, Marla Ann Fisher

Dissertations

Polychlorinated biphenyls (PCBs) are a major contaminant of global extent in water resources and aquatic biota. Due to its high lipid solubility, PCBs fail to be degraded and, therefore, continue to bioaccumulate throughout the environment and food chain. To determine the impact of PCBs on the immune system ofaged and juvenile Japanese medaka (Oryzias latipes), fish were injected with the coplanar PCB congener 126 and examined after 3 and 14 days. PCB 126 produced oxidative stress in both age groups of fish 14 days post-injection; however, juvenile medaka appeared more susceptible than aged fish. Humoral immunity, as determined by antibody …

Chemical And Isotopic Investigation Of Groundwater In Eastern United Arab Emirates (Uae), Ahmed Ali Abdalla Murad

Dissertations

UAE is located at the southeast of Arabian Peninsula. Two main aquifers occupy the study area: the Eastern Gravel Plain and Ophiolite aquifer. Increasing salinity of groundwater and depletion of aquifers are a major concern in the UAE. Previous studies suggest that groundwater, particularly in the Eastern Gravel Plain aquifer, is affected by seawater intrusion and evaporation. Isotopes of oxygen, hydrogen, carbon and chlorine, and chemical analyses were used to investigate this problem in detail. Samples of groundwater from the Eastern Gravel Plain aquifer have R³⁶Cl values in the range of 13.3 to 17.4 x10^-15 while those …

Continuous And Interrupted Exposure Therapy In The Treatment Of Public Speaking Anxiety, Stacey A. Waller

Dissertations

Current research suggests that exposure-based interventions are the treatment of choice for anxiety disorders (Barlow & Wolfe, 1981; Barlow, 1988; 2002; Zinbarg, Barlow, Brown, & Hertz, 1992; Foa, Rothbaum, & Kozak, 1989). While the evidence to date supports the efficacy of these procedures, the precise mechanisms by which they achieve symptom reduction are not yet fully understood. Most theoretical explanations of exposure therapy appeal to the respondent and operant conditioning processes from which the procedure was originally derived. While it is frequently argued that in order to achieve operant and respondent extinction, exposure must be delivered continuously, without interruption (Barlow, …

The Use Of Computer-Based Programmed Instruction As A Supplemental Tool To Train Behavior Analysis Concepts, Jason T. Otto

Dissertations

The objective of this dissertation was to produce effective computer-based programmed instruction modules to serve as supplemental training for an ongoing college seminar in behavior analysis. Computer-based programmed instruction supplemented a checklist of a strategy for diagramming behavioral contingencies in the first study and supplemented difficult textbook material in the other studies. In all, the instruction involved 31 concepts, rules, or objectives. Microsoft ®PowerPoint® and Macromedia Flash(TM) were the authoring tools used to develop these supplemental modules.

Virtual Teams Combining Mobile Devices With Web-Based Communication On Group Decision Making, Hyo-Joo Han

Dissertations

Organizations have moved from a face-to-face team environment to a virtual team environment using communication technology during the last decade. More and more workers use asynchronous tools (including email, discussion groups, information sharing tools, and group calendaring systems), and synchronous tools, such as instant messaging and web-based chatting features, to coordinate and share information with people within and outside of organizations. This empirical study on how virtual teams work, integrating mobile devices with web-based group communication for decision-making tasks, examines which technologies and communication modes are the best for distributed group teamwork, and, mainly, what are the predictive characteristics making …
