Changes In Environmental Context And The Mirror Effect In Recognition Memory, Craig Andrew Livermore

Theses and Dissertations (Comprehensive)

The present study examined the effect of environmental context on the mirror effect in recognition memory. In seven experiments, participants studied either high (HF) and low-frequency (LF) or noun and nonnoun pairs of words followed in a old/new item recognition test by which proportion correct, response time, and confidence judgments were measured. Single item or word pair targets and distractors were presented in same- or different-context conditions. Context was defined as the unique combination of foreground and background colour and position on a computer screen for two experiments while position was removed as a context variable for five experiments due …

Non-Volatile Dissolved Organic Iodine In Marine Water, Xianhao Cheng

OES Theses and Dissertations

An analytical scheme for the determination of marine DOI has been established. The concentration of DOI is estimated as total iodine (TI) minus total inorganic iodine (TII). The concentration of total iodine is determined as [special characters omitted] after DOI has been oxidized to inorganic iodine quantitatively by intensive UV-irradiation and all the inorganic iodine in the samples had been converted to [special characters omitted] by the addition of NaClO.

Production of DOI in seawater can be via both non-phytoplankton and phytoplankton related processes. In the former, iodide is converted to DOI. In the latter, most likely, iodate is converted …

Error-Correcting Codes Associated With Generalized Hadamard Matrices Over Groups, Iem H. Heng

Mathematics & Statistics Theses & Dissertations

Classical Hadamard matrices are orthogonal matrices whose elements are ±1. It is well-known that error correcting codes having large minimum distance between codewords can be associated with these Hadamard matrices. Indeed, the success of early Mars deep-space probes was strongly dependent upon this communication technology.

The concept of Hadamard matrices with elements drawn from an Abelian group is a natural generalization of the concept. For the case in which the dimension of the matrix is q and the group consists of the p-th roots of unity, these generalized Hadamard matrices are called “Butson Hadamard Matrices BH(p, q)”, …

Municipal Involvement In International Relations, John Jack William Hilgers

Theses and Dissertations in Urban Services - Urban Management

The purpose of this study is to examine municipal involvement in international relations in the United States. This municipal phenomenon is occurring concurrently with both a shift away from the traditional nation-centric structure of international relations under the influence of globalism as well as a sharp decline in intergovernmental aid. The research questions were: (1) What are the indicators that define municipal involvement in international relations? and (2) What is the extent of that involvement?

Extensive qualitative and research was conducted in the form of an exploratory literature survey which was set forth in narrative analysis to overcome the paucity …

A Hierarchical Filtering-Based Monitoring Architecture For Large-Scale Distributed Systems, Ehab Salem Al-Shaer

Computer Science Theses & Dissertations

On-line monitoring is essential for observing and improving the reliability and performance of large-scale distributed (LSD) systems. In an LSD environment, large numbers of events are generated by system components during their execution and interaction with external objects (e.g. users or processes). These events must be monitored to accurately determine the run-time behavior of an LSD system and to obtain status information that is required for debugging and steering applications. However, the manner in which events are generated in an LSD system is complex and represents a number of challenges for an on-line monitoring system. Correlated events axe generated concurrently …

Evaluating The Case For Social Security Reform: Elderly Poverty, Paternalism And Private Pensions, Maria O'Brien

Faculty Scholarship

This Article considers the many arguments currently being made in favor of Social Security pension reform and evaluates each of them in terms of the principal Congressional goal of the program-the elimination of elderly poverty-as well as more recent goals that have been articulated by subsequent commentators such as a reduction in government paternalism and the maximization of retirement income. The Article begins with a short history of the public pension program in the United States and considers at length the details of the various reform proposals that currently enjoy support. In addition it examines the enormously regressive tax structure …

Reliability Of The Dynamic Gait Index In Vestibular Disorders, Diane M. Wrisley

Rehabilitation Sciences Theses & Dissertations

The purpose of this study was to examine the inter-rater and intra-rater reliability of the Dynamic Gait Index (DGI) when used with patients with vestibular disorders. Subjects included 30 patients aged 27-88 years, with vestibular disorders, who were referred for vestibular rehabilitation. Subjects' performance on the DGI was concurrently rated by two physical therapists experienced in vestibular rehabilitation to determine inter-rater reliability. To determine intra-rater reliability each subject repeated the DGI one-hour later. Percent agreement and kappa statistics were calculated for individual DGI items. Kappa statistics for individual items were averaged to yield a composite kappa score of the DGI. …

Placement Of Piezoelectric Actuators For Active Control Of Vibration Using Modal Parameters, Xuegeng Zhu

Mechanical & Aerospace Engineering Theses & Dissertations

An equation is derived to model the piezoelectric actuators incorporation with flexible structures. This equation permits the comparison of the performance indices over the entire structure for a piezoelectric actuator with constant area, which is unachievable if the Finite Element Method is used for complicated structures.

An index has been developed for placement of piezoelectric actuator for control of vibration of a flexible structure. This index is derived from the definition of H2norm. Computation of the proposed index requires only the natural frequencies and corresponding mode shapes of the structures of interest. The method is well suited to large …

Three Essays On European Union Advances Toward A Single Currency And Its Implications For Business And Investors, Charlotte Anne Bond

Theses and Dissertations in Business Administration

The first chapter examines the changes in various European currencies' exchange rates through the time period 1980 through 1997. Specifically, we are interested to determine if there is any affect to the volatility of these exchange rates and specific events related to the advancement of European Unification. In order to move to a single currency it is imperative that the separate currencies become less volatile to facilitate the move to a single currency. In this study, we examine whether this is the case and discuss which currencies appear to display this behavior. It is observed that of the 14 currencies …

Ecology Of The Eastern Cottonmouth (Agkistrodon P. Piscivorus) At Back Bay National Wildlife Refuge: A Comparative Study Of Natural And Anthropogenic Marsh Habitats, Chad Lee Cross

Biological Sciences Theses & Dissertations

Mark-recapture sampling and radiotelemetry were used to investigate populations of the eastern cottonmouth, Agkistrodon p. piscivorus, in both natural and anthropogenic marsh habitats at Back Bay National Wildlife Refuge (BBNWR), Virginia Beach, Virginia from autumn 1995 to late spring 1998. Mark-recapture subjects were captured, marked by ventral scale-clipping, and released back into the population. A modified Schnabel Census estimator was used to estimate population sizes and corresponding densities in both marsh systems based on a total of 244 captures of 222 individuals. Most snakes were found >0.05 in from water, but it was apparent that proximity to water played …

Intellectual Property As Price Discrimination: Implications For Contract, Wendy J. Gordon

Faculty Scholarship

As people become enamored with the possible benefits of allowing price discrimination in contracts for intellectual goods, they should realize that traditional intellectual property law works by fostering price discrimination among customers. This simple fact has implications for federal pre-emption, and is a reminder of the complexity of the economic issues involved. Increasing a seller's ability to price discriminate will often involve increasing his monopoly power, with dubious welfare effects.

Locating A Mate In 3d: The Case Of Temora Longicornis, Michael H. Doall, Sean Colin, J. Rudi Strickler, Jeannette Yen

Arts & Sciences Faculty Publications

Using laser optics to illuminate high–resolution video–recordings, we revealed behavioural mechanisms through which males of the calanoid copepod species Temora longicornis locate females. Males of T. longicornis swam at significantly faster speeds than females along more sinuous routes, possibly reflecting adaptations to increase encounter with females. Upon approaching within 2 mm (i.e. two bodylengths) of a female's swimming path, males accelerated to significantly higher pursuit speeds. Pursuit trajectories closely traced the trajectories of females, suggesting that males were following detectable trails created by swimming females. Males of T. longicornis detected female trails up to at least 10 s old, and …

Managing Urban Water Resources In A Developing Economy: The Case Of Owerri, Nigeria, Lawrence Chidi Anukam

Theses and Dissertations (Comprehensive)

Projections indicate that the disparity in population numbers will widen further by the year 2025 when the global population is expected to be 8.5 billion, and at that time about 84% will be living in the developing countries (World Resources Institute, 1992). The greatest proportional increase will occur in Africa, where the population is projected to nearly triple, from a 1990 level of 642 million to 1.6 billion in 2025. In 1997, the population of Nigeria alone was about 100 million, making it the largest country, in terms of population, in Africa. From 1960 to 1990, the average annual population …

Mapping Mediation: The Risks Of Riskin's Grid, Kimberlee K. Kovach, Lela P. Love

Articles

We use maps for orientation and guidance. A topographical map and compass guide us through unmarked terrain. To pass a bar exam, law students follow a course carefully mapped out by BAR/ BRI. To understand political configurations, we study maps of the world, indicating countries and states and their boundaries. Maps are important. They create paradigms or "boxes" within which to operate safely and efficiently. The universe a map depicts-what is put in and what is left out-must have an internal cohesion, logic, and accuracy. If not, maps misguide their users.

Radium-226 As A Tracker Of Ground Water Input To The Coastal Waters Of Southern Rhode Island, Margaret K. Scott

Open Access Master's Theses

Submarine ground water discharge (SGWD) represents a significant, yet diffuse and largely neglected source of fresh water and dissolved constituents to the coastal environment. Quantification of this term therefore proves important with respect to coastal hydrological and geochemical mass balances. In order to better constrain SGWD to southern Rhode Island's coastal waters, the naturally-occurring radionuclide ²²⁶Ra was used as a tracer of ground water input.

Activities of ²²⁶Ra were determined in river water, salt ponds, coastal ocean and ground water in southern Rhode Island during the summer of 1997 (June-August). Coastal lagoons and shelf waters were analyzed to …

The Total Synthesis Of A Conformationally Constrained Organophosphorus Analog Of Acetycholine, Justin Mergott '98

Honors Projects

We propose the total synthesis of a conformationally constrained organophosphorus analog of acetylcholine (5, Scheme 5). This compound will contain two crural centers, one being the phosphorus atom and the other being the pyrrolidine ring carbon beta to the phosphorus atom. The chiral beta carbon is conformationally constrained because it is part of the pyrrolidine ring. Studies with such a compound should allow us to make substantial progress towards the clarification of the stereospecificity of AChE inhibition by OP compounds and eventually help us understand more about the structure of the AChE active site. The synthesis begins with Cbz-L-proline methyl …

Logiccity: On-Line Digital Logic Simulator, Jihad Z. Almahayni

Open Access Master's Theses

A primary challenge for science educators is to develop ways to help students understand new ideas that cannot be directly observed. The application of computer simulations is one method instructors may use to address the problem of teaching for conceptual understanding. The use of computer simulations for science teaching is increasing steadily because simulations provide students with the opportunity to witness or "perform" experiments that might otherwise be too expensive, too time consuming, or too dangerous for them to do in the lab. Simulation, in general, is a very effective way for both a student and a professional to visualize …

The Effects Of Systematically Fading Reinforcement While Maintaining Skills, Jodi Suzanne Bronson

Dissertations and Theses @ UNI

A review of the literature describing treatment programs for young children with autism revealed two distinctly different strategies. One, the Lovaas approach (Lovaas, 1987), focused on an intense, one-on-one discrete trial training format implemented for approximately 40 hours per week. A prescribed curriculum targeted at social and communication skills is incorporated. The second program, TEACCH, emphasized an individualized curriculum selected after a careful assessment process to determine a person's strengths and limitations. Goals and objectives were subsequently implemented in highly structured special education classrooms where the focus was on antecedent control and the use of visually mediated strategies. Interviews with …

Database Security: Evaluation Of A Multi-Policy Access Control Model, Fei Dong

Dissertations and Theses @ UNI

As an increasing number of organizations become dependent on access to their data stored in the database, the need for adequate security measures is becoming more and more critical. Enforcing data protection means safeguarding data from unauthorized or improper disclosures or modifications. Access control policies should be independent of the mechanisms that will implement the physical control of access: this allows control mechanism to be available for different policies. Although considerable work was done on access control models and related mechanisms for databases (Castano & Fugini, 1994), current access control models and mechanisms are not flexible enough to meet the …

The Predictive Effectiveness Of Previous Offensive Play Selections On Future Play Selections In College Football, Ross Michael Els

Dissertations and Theses @ UNI

The popularity of college football is indisputable. In 1987, over 350 million people attended NCAA football contests which pushed the three year attendance figure from 1985 to 1987 to over one billion. Because of this popularity, however, intense pressure to win has been placed on players, coaches and administrators. To confound the problem, offenses have grown in complexity since the early years of college football. To assist teams in preparing for upcoming opponents, coaching staffs view films of the opponent's previous games. The coaches gather information from the films and develop tendencies in hopes that the upcoming opponent will repeat …

Corporate Executive Perspective Of Worksite Health Promotion Programs, Barbara E. Gay

Dissertations and Theses @ UNI

Health promotion programs at the workplace are increasing in popularity for both large and small businesses across the United States. The workplace has been recognized as a favorable setting for health promotion programs because it provides a captive audience for promoting health. The workplace also provides the employee with an opportunity for support in making healthy lifestyle changes. Numerous studies have documented that worksite health promotion programs will improve employee health and morale, increase productivity, and decrease absenteeism. Comparing the cost to the benefits is often the basis for making business decisions, including the decision to implement a health promotion …

Profile Of Adolescent Gambling Behaviors In Black Hawk County High School Students Ages 14-18, Holly A. Helm

Dissertations and Theses @ UNI

As gambling opportunities increase, adolescents are exposed to more forms of gambling and may be developing problematic gambling behaviors. Research seems to indicate a "growing trend that pathological gambling is becoming more common among young Americans" (Kerr, 1998, p. 27). Thus, the purpose of this study was to profile adolescent gambling behaviors that exist in Black Hawk County high school students between the ages of 14-18. In particular, this study sought to: (a) define adolescent perceptions of gambling; (b) tabulate the percentages of youth who are engaged in gambling activities; (c) identify money gambled; (d) examine who influences gambling behaviors; …

Observations Of Nonlinear Wave Spectra In Open Ocean And Shallow Coastal Waters, Andrey V. Karachintsev

Open Access Master's Theses

The experimental data from the Risø Air-Sea Experiment (RASEX) and the Marine Boundary Layers (MBL) experiment are used to investigate the nonlinear coupling effects among different frequency components in surface wave field under both fetch-limited finite depth conditions and open ocean conditions. The wavenumber-frequency spectra are calculated using the Maximum Likelihood Method (MLM). The reliability of the MLM is tested using computer-simulated wave fields. The frequency power spectra from the shallow water RASEX experiment reveal that the slopes of the equilibrium range are close to the f^-4 dependence. On the other hand, the equilibrium range spectra from the open-ocean …
