Waterford Crystal: The Chairman's Challenge, Gerry Mortimer

Case studies

As he eased his car out the gates of Castlemartin on a lovely evening in May 1995, Redmond O’Donoghue mused on the meeting which had just finished. Dr A.J.F. O’Reilly, non executive Chairman of Waterford Wedgwood Plc, had brought senior management of the group to his Irish residence in County Kildare for an informal discussion on future strategy. The group comprised two distinct major subsidiaries, Waterford Crystal which produced crystal glass and Josiah Wedgwood whose main business was ceramic tableware. Redmond was Chief Operating officer of Waterford Crystal. With the impending retirement of the current Chief Executive, Paddy Galvin, Redmond …

Dear Mr. or Ms. English Teacher:

I hope that by the time this arrives the hectic first days and weeks of school are behind you and that you are settled into the work that you and I both love teaching young people about writing, language and of course, literature. I have a keen interest in your work this year, not just because I, too, am a teacher, but also because three of my children are in your English classes. Joanne, my youngest, is in eighth grade and looking forward to her last year of middle school. Carrie, a ninth grader, …

The Case Of Pearl S. Buck: Neglect And Abandonment Vs. Recognition And Recovery, Linda K. Adkins

Dissertations and Theses @ UNI

Pearls. Buck was the third American to win the Nobel Prize for Literature, the first American woman to win this Prize, and only the fourth woman in the world to do so. Taking into consideration the Nobel Prize and all the additional honors and awards Buck and her writing received, it is odd that she has been abandoned by American literary critics. Therefore, it is the goal of this thesis to identify reasons why Pearl Buck and her works have been neglected, and to provide significant reasons why she and her work should be recognized and studied. The first part …

A Divided Attention Task To Measure Functional Auditory Comprehension Deficits In Aphasia, Bruce Dewayne Bane

Dissertations and Theses @ UNI

This experiment assessed auditory comprehension in the presence of a divided attention task. Words and nonwords were embedded within the commands of the first subtest of the Revised Token Test (RTT) to comprise the divided attention RTT (dRTT). A statistically significant poor performance was found on the dRTT compared to the RTT. Further, the subjects' performance was found not to change from the beginning to the end of the dRTT suggesting that learning and fatigue were not meaningful variables in their performance. The position of the distractor (e.g., opposite the verb, color adjective, noun, or randomly placed) had mixed affect …

Making Sense Of The At-Risk Phenomenon, Karri Elizabeth Beath

Dissertations and Theses @ UNI

The purpose of this qualitative study is to help in making sense of the at-risk phenomenon. The implications throughout this study are based on the constructivist paradigm in that we create things such as at-risk and not discover them, therefore, allowing us to change the way things are. The data collected throughout this study developed into four main contradictions. The first contradiction, We Can't Define At-Risk, but Treat It Like a Thing, presents a variety of definitions of at-risk which represent the inability to define such an ambiguous term. The second contradiction, Moving Towards Inclusion During the Creation of Another …

The Relationship Between Attention Deficit Hyperactivity Disorder And Aggression In Children: A Cross-Sectional Study, Eric Wayne Boelter

Dissertations and Theses @ UNI

This study examined the correlation between aggression and ADHD symptoms across several age groups in children. Participants were elementary and secondary students recruited from grades 1st through 12th in a suburban, university-affiliated laboratory school (N = 426). The students' teachers also participated in the study. The study consisted of administering questionnaires to students and teachers. These included: (a) The Self-Report Inventory, (b) The Peer Nomination Inventory, and (c) The Teacher Report Inventory. All of these measures were designed for this study. One way analysis of variance for gender showed that males were more aggressive and had more ADHD symptoms than …

Portfolio Assessment In High School Chemistry, Mark M. Laporte

Dissertations and Theses @ UNI

This is a report of one high school chemistry teacher's experience of implementing portfolio assessment in his classroom. This project was carried out using a teacher as researcher model. The chemistry classes were p1imarily composed of 11th grade students in a rural midwestern high school setting. This thesis reviews some of the literature regarding alternative assessment focusing particularly on the literature related to portfolio assessment. The chemistry portfolio design is explained in detail including a rationale for each of the portfolio elements. The teacher developed nine portfolio elements of which the students were required to complete five. The nine elements …

Sex, Violence, And Hand Puppets: History And Structure Of Punch And Judy Performance Tradition, James Robert Davis

Dissertations and Theses @ UNI

Punch and Judy are characters who exist only within the boundaries of the puppet theatre, in performances where characters are portrayed by inanimate figures. Nonetheless, the history of the puppet theatre, and particularly that of Punch and Judy, is closely related to the history of more widely accepted, actor-based theatre, where characters are portrayed by human beings. While the two traditions-share many common elements--such as the importance of characterization, direction, and design--the essential difference between actor-theatre and puppetry is the manner in which the performance is presented. The approach of this study is threefold: first, a linear history of the …

Influence Of Chemical Reactions In Magnesia-Graphite Refractories: Ii, Effects Of Aluminum And Graphite Contents In Generic Products, Carmen Baudín, Carlos Alvarez, Robert E. Moore

Materials Science and Engineering Faculty Research & Creative Works

A group of magnesia-graphite and magnesia-graphite-aluminum materials, the compositions of which represent a wide range of graphite contents (approximately 10-16.4 wt.%), aluminum contents (0-5.2 wt.%), and MgO and graphite qualities, were fabricated, using standard commercial practices. Chemical analysis and determination of room-temperature modulus of rupture (MOR) and Young's modulus, as well as a complete microstructural characterization of the as-received materials, were performed. Mechanical characterization at high temperature (1000°, 1200°, and 1450 °C) was done in terms of Young's modulus and MOR in an argon atmosphere (°C). Modulus-of-elasticity values ranged from 4 to 16 GPa, and their evolution with temperature was …

Physical Activity Patterns Among Physical Education Major Students In Selected Institutions Of China And The United States, Wei Bian

Dissertations and Theses @ UNI

The benefits associated with regular physical activity have been well documented in recent years. Numerous studies have investigated physical activity patterns among children, adolescents, and adults, yet little work to date has examined the patterns of habitual physical activity participation among pre-service physical education (PE) majors. Furthermore, inasmuch as physical activity affords health benefits irrespective of one's nationality or culture, comparisons among the peoples of nations around the world becomes of greater interest.

This study was designed to examine the leisure-time physical activity patterns of physical education major students in selected institutions from the People's Republic of China (PRC) and …

Pre-Performance Routines And Rhythm: A Comparative Study, Blake Wade Miller

Dissertations and Theses @ UNI

The present study was designed to investigate the effects of pre-performance routine rhythm on novel motor task success. At the center of the study was the comparison of differing characteristics of two theories of motor control: the dynamical systems theory and the schema theory. It was hypothesized that an even pre-performance routine rhythm would be more advantageous to task success than an uneven preperformance routine rhythm, regardless of the rhythmic characteristic of the task. The results concluded the contrary to be more accurate, and indicated that task success was more likely to occur when the pre-performance routine rhythm was congruent …

Structural Disorder And The Origin Of High-Tc Suppression In La₁.₈₇₅Ba₀.₁₂₅ Cuo4−Δ, Daniel Haskel, Edward A. Stern, Fatih Dogan, Arnie R. Moodenbaugh

Materials Science and Engineering Faculty Research & Creative Works

Polarized x-ray absorption fine structure (XAFS) measurements at all La, Ba and Cu sites were used to study local structural features that accompany the strong Tc suppression at: r,,, 1/8 in La₂BaCuO₄. Two critical parameters regulating the strength of hole-lattice coupling in this material were determined, ie, the direction and magnitude of CuO₆ octahedra local tilts. Our findings include the existence of large disorder in the magnitude of the tilt angle about its average value (0), with an rms~~ 2 (0). We suggest that this large disorder strongly scatters a large fraction of states at …

Analog Hardware Implementation Of Continuous-Time Adaptive Filter Structures, John G. Harris, Jui Kuo Juan, Jose C. Principe

Electrical and Computer Engineering Faculty Research & Creative Works

We have implemented a four-tap adaptive filter in a continuous-time analog VLSI circuit. Since an ideal delay is impossible to implement in continuous-time hardware, we implemented the delay line as a cascade of low-pass filters (called the gamma filter). Since many years of research in our lab has shown that the gamma filter outperforms the ideal delay line for a wide range of applications, the gamma filter should not be considered merely a crude approximation of the ideal delay line. We show measured results from an analog chip that solves the problem of system identification-identifying an unknown linear circuit from …

In-Clip Search Algorithm For Content-Based Audio Retrieval, Punpiti Piamsa-Nga, Nikitas A. Alexandridis, Sanan Srakaew, George C. Blankenship, S. R. Subramanya

Electrical and Computer Engineering Faculty Research & Creative Works

Researchers are currently more interested in searching for fragments that are similar to a query, than a total data item that is similar to a query; the search interest is for "contains", not "is". The paper presents an O(logn) algorithm, called the "generalized virtual node (GVN)" algorithm; the GVN algorithm is a search algorithm for data fragments that have similar contents to that of a query. An example of the use of the GVN algorithm is in the search of a database of audio recordings for a few measures of a melody. Each audio clip is transformed into characteristic features …

A Distributed Algorithm For The Classification Of Images On A Network Of Workstations, S. R. Subramanya

Electrical and Computer Engineering Faculty Research & Creative Works

Image databases require content-based queries and retrievals. Fast and accurate retrievals for user queries depend on efficient indexing and searching schemes. The classification of images into different categories (classes) is an important task which facilitates the indexing and searching process. The classification of huge amounts of image data place enormous demands on computational requirements. Network of workstations (NOWs, also sometimes called clusters) are a cost-effective way of providing the much-needed computational power in such applications. This paper presents a distributed scheme for the classification of images in an image database, using a network of workstations. The results of the classification …

Use Of Transforms For Indexing In Audio Databases, S. R. Subramanya, Abdou Youssef, Bhagirath Narahari, Rahul Simha

Electrical and Computer Engineering Faculty Research & Creative Works

The phenomenal increases in the amounts of audio data being generated, processed and used in several computer applications have necessitated the development of audio database systems with newer features, such as content-based queries and similarity searches, to manage and use such data. Fast and accurate retrieval for content-based queries is crucial in order for such systems to be useful. Efficient content-based indexing and similarity searching schemes are keys to providing fast and relevant data retrieval. This paper studies and evaluates the different parameters involved in an indexing scheme which uses transforms (as used in signal processing) for generating the audio …

Hypersonic Drag And Heat Transfer Reduction Using A Forward Facing Jet, Benjamin Meyer, Harlan F. Nelson, David W. Riggins

Mechanical and Aerospace Engineering Faculty Research & Creative Works

A two-dimensional numerical study of the effects of a forward-facing jet located at the stagnation point of a blunt body on wave drag, heat transfer, and skin friction drag is presented for Mach 6.5 flow at 30 km altitude. The full Navier-Stokes equations are used with variable viscosity and thermal conductivity. It is shown that upstream injection can significantly modify the flow field. If the jet conditions are chosen properly, large reductions in drag and heat transfer can be obtained resulting in possible increases in the volumetric efficiency and static stability of aircraft and reductions in heating protection requirements for …

A New Reflection Free Boundary In Uniform Flow Using Mapped Infinite Wave Envelope Elements, Walter Eversman, Indranil Danda Roy

Mechanical and Aerospace Engineering Faculty Research & Creative Works

Variable order mapped infinite wave envelope elements are developed for finite element modeling of acoustic radiation in a uniformly moving medium. These elements can be used outside of the near field as a non-reflecting boundary condition for computations on an infinite domain in which a radiating body is immersed in a moving medium. Mapped infinite wave envelope elements provide a boundary condition equivalent to stiffness, mass, and damping matrices appended to the inner mesh. A demonstration of the characteristics of the mapped infinite wave envelope elements is given in the context of acoustic radiation from a turbofan inlet for which …

Search For Charginos And Neutralinos In E+E- Collisions At Centre-Of-Mass Energies Near 183 Gev And Constraints On The Mssm Parameter Space, R. Barate, M. Thulasidas

Research Collection School Of Computing and Information Systems

Searches for charginos and neutralinos are performed with the data collected by the ALEPH detector at LEP at centre-of-mass energies near 183 GeV. In these searches, it is assumed that R-parity is conserved and that the lightest neutralino is the LSP. No evidence of a signal is observed in the 57 pb−1−1 accumulated, which excludes chargino and associated neutralino production up to the kinematic limit over large regions of the MSSM parameter space. Under the assumptions of common gaugino and common sfermion masses at the unification scale, the interplay between the chargino, neutralino and slepton exclusion limits allows a lower …

Voices In The Fire, James Harrold

Dissertations and Theses @ UNI

"Voices in the Fire" is a memoir which culminates three main themes: child abuse, mental illness, and Asian American identity. The theme of child abuse deals with domestic violence suffered at the hands of an alcoholic father, my mother withstanding the deliberate beatings, standing in my place so I could be saved. The child abuse influences later patterns of my adult mental condition, causing self-repudiation of Asian American heritage. In the memoir, I seek out counseling at the suggestion of a friend. I feel unstable and uncertain about what's happening around me. When I go to the mental health center, …

Adolescent Depression : Further Examination Of Gender Differences, Elizabeth Marie O'Neill

Dissertations and Theses @ UNI

This study was designed to examine pertinent research questions that remain unanswered by past investigations of adolescent depression. Specifically this study investigated potential differences between high and low scoring depressed adolescents, and whether gender is an influential variable for consideration. Subjects were 175 adolescent boys and girls from a laboratory school in Midwestern Iowa. Subjects were divided into four groups based on gender and responses two questions on the BDI-A. Specifically, the four groups were: boys who scored at or above IO on the BDI-A (sub-clinical group--boys), boys who scored below 10 on the BDI-A (control group--boys), girls who scored …
