This study examined the effects of a productivity-indexed pay for performance plan in a professional services firm. The new plan was implemented after productivity decreased under an existing plan. Performance of staff and senior level accountants was analyzed across three departments under a three-year baseline and a two-year intervention period. Several measures of productivity indicated that the intervention was effective in improving production, especially for employees with full annual workloads. Percentage of salaries earned in incentives was comparable for both the baseline and intervention periods. Possible explanations for trends in the data, weaknesses in the plan, and implications for future research are also discussed.

This study sought to determine whether a relationship existed between individual salesperson's levels of goal-directed cognition and motivation and their professional success as determined by the percentage of sales goals achieved. Salespersons represented two companies with national sales forces: one from the financial services industry and one from the apparel manufacturing industry. Both groups of salespeople were responsible for complex selling tasks. The skill sets for these professionals included high levels of communication skills, extensive product knowledge, and competitive market knowledge. Survey research, both paper and pencil and online, was conducted using the Hope Scale developed by C. R. Snyder and associates (1991). Hope is defined as a two-dimensional construct of goal-directed thinking: resourcefulness, thoughtful planning to overcome obstacles to goals, and motivation, cognition to sustain momentum toward goal achievement. Theoretically, upon assessing salespersons' Hope scores, organizations would be better prepared to assist those with low Hope Scale Scores (HSS) in one of the two areas. Those with low resourcefulness scores could be trained in cognitive techniques to overcome obstacles to goal achievement. Those with low motivational scores would be identified for further analysis, from a developmental perspective, to better determine what personally initiates and sustains motivation to attain their …

The rheology of 1-8% hydroxypropyl cellulose (HPC) solutions has been studied in the temperature range of 20-45 degrees Celsius. The results showed that the relative viscosity at each HPC concentration decreases with increasing temperature. The relative viscosity decreases drastically at about 43 degrees Celsius due to a phase transition. The influence of anionic surfactant, sodium dodecylsulfate (SDS), induced gelation of a 2% HPC solution. The HPC solutions gelled at surfactant SDS concentrations ranging from 0.4 to 1.0 critical micelle concentration (CMC). The gelation of the HPC/SDS hydrogel is explained in the surfactant SDD - bridged HPC linear polymer chains. The complex viscosity - concentration profile was determined below the CMC of the SDS - water pair. The peak itself was a function of frequency indicating the presence of two relaxation times within the gelled network.

The first chapter of this descriptive paper outlines a problem, proposes a solution and poses three questions for me to answer after completion of research. The problem was to bring an emerging ceramic style into all of my pieces rather than just the few I have mastered. The solution was to create three sets of new forms and make them repeatedly until they boasted the sought-after style. Chapter 2 chronicles the research of creating, morphing, detailing and finally mastering these new forms. Chapter 3 summarizes the experience and answers the three aforementioned questions: (1) What is my personal definition of a successful pot? (2) How does the undulating style affect the functionality of the pot? (3) How does the Campbell tartan glazing complement or detract from the pot's form?

Mobile agent technology presents an attractive alternative to the client-server paradigm for several network and real-time applications. However, for most applications, the lack of a viable agent security model has limited the adoption of the agent paradigm. This thesis presents a security model for mobile agents based on a security infrastructure for Computational Grids, and specifically, on X.509 Proxy Certificates. Proxy Certificates serve as credentials for Grid applications, and their primary purpose is temporary delegation of authority. Exploiting the similarity between Grid applications and mobile agent applications, this thesis motivates the use of Proxy Certificates as credentials for mobile agents. A new extension for Proxy Certificates is proposed in order to make them suited to mobile agent applications, and mechanisms are presented for agent-to-host authentication, restriction of agent privileges, and secure delegation of authority during spawning of new agents. Finally, the implementation of the proposed security mechanisms as modules within a multi-lingual and modular agent infrastructure, the Distributed Agent Delivery System, is discussed.

The objective of this research was to investigate lead speciation in the soil/sediment-water environment and to better understand how the species affect lead mobility under different environmental conditions. The research involved both field soil and sediment samples as well as standard lead solutions. Field samples were fully characterized and extracted by aqueous and organic solvents. The results were compared and evaluated with the metal speciation model, MINTEQA2. Hydrolytic polymerization and organic complexation studies were conducted with standard lead solutions under controlled experimental conditions. Results of the field samples showed that pH, dissolved cations, ionic strength, dissolved organic matter, and nature of the soil/sediment matrix play major roles in the distribution and mobility of lead (Pb) from contaminated sites. In the aqueous equilibration experiment, the magnitude of Pb2+ solubilization was in the order of pH4>pH7>pH9. The results were in good agreement with MINTEQA2 predictions. An important finding of the research is the detection of Pb polymerization species under controlled experimental conditions. At pH 5.22, Pb polymeric species were formed at rate of 0.03 per day. The role of Pb complexation with organic matter was evaluated in both field and standard samples. Different methodologies showed three types of organically bound Pb. A …

Many studies have been completed on factors affecting judicial decisions. Studies have focused on civil rights cases, economic cases, criminal cases, sexual discrimination and obscenity cases, but no work has specifically looked at religious liberty cases. This work examines the factors affecting United States Courts of Appeals judges' decision-making in religious liberty cases. I hypothesize that gender, race, religious background, prior judicial experience, circuit, region and litigant status will all influence the way judges vote in religious liberty cases. The explanatory power of this study is relatively low, but the results indicate that judges follow the law when making decisions in religious liberty cases.

All information for this study was obtained by original source documents, interviews with the principal participants and the personal observations of the writer. A complete transcript of interviews with Daron Aric Hagen Michael Haithcockand Robert De Simone are included as appendices. In1961 the College Band Directors National Association (CBDNA) created its commissioning project for the purpose of contracting prominent composers to contribute works of high quality to the growing wind repertoire. Recently, CBDNA commissioned works that sought to collaborate with other disciplines within the artistic community. These collaborative works added new depth to the wind repertoire and helped advance the genre to new levels of prominence. CBDNA commissioned Daron Aric Hagen to write an opera using winds in the pit. He titled the work Bandanna, based on Shakespeare's Othello. Hagen contracted Paul Muldoon to write the libretto. A consortium of 79 member schools contributed to the project. A total of $100,000.00 was paid to the composer. The Director of Bands at Baylor University conducted the premiere performance of Bandanna during the 1999 CBDNA convention on 25 February 1999. Hagen assigned instrumental, thematic and harmonic attributes to each character. There are literally thousands of interactions between these elements that weave a …

The argument of this paper is that certain salient passages in the New Testament concerning Christology, as it was defined in the Nicene creed in A.D. 325, reflect such orthodoxy better in the Textus Receptus Greek texts and the English translations made from them than do the Alexandrian texts. Arian theology, which was condemned as heretical at Nicea, is examined. Patristic quotations, historical texts, and arguments of the scholars are cited and traced, along with a comparison of Christological verses.

This descriptive survey study investigated the value of faculty practice among Commission of Collegiate Nurse Education (CCNE) Accredited Nursing Schools. The sample included all CCNE accredited schools that offered a Masters degree. Subjects from the 66 schools in the sample the dean and three Nurse Practitioner faculty who are teaching a clinical course. Response rate was 51% for the deans and 35% for the faculty. The opinions of deans were compared to the opinions of faculty on the views of faculty practice as research and the incorporation of faculty practice in the tenure and merit review system. The results showed faculty and deans differed on the value of faculty practice as research. However, only 6.5 % of statistically significance difference was contributable to whether the response was from a dean of a faculty. There was no significant difference to the inclusion of faculty practice in the tenure and merit review system. Boyer's expanded definition of research was used as a theoretical background. Deans viewed faculty practice more important as compared to the traditional faculty expectation of research than faculty did. The operational definition of faculty practice was that it required scholarly outcomes from the practice. Deans were more willing than …

This study examined educators' preferences for learning technology integration skills in order to provide the education community with justifiable data concerning the need for educator training alternatives. A survey was distributed to compare preservice educators, inservice educators, and professional development personnel's perceived effectiveness of eight training methods (N=759). The four research questions examined were: Do differences exist among preservice educators, inservice educators, and professional development personnel in the perceived effectiveness of different methods for learning technology integration skills? (2) Do differences exist among preservice educators, inservice educators, and professional development personnel in the perceived effectiveness of different methods for learning technology integration skills when categorized by age? (3) Do differences exist among preservice educators, inservice educators, and professional development personnel in the perceived effectiveness of different methods for learning technology integration skills when categorized by total hours of instruction? (4) Do differences exist among preservice educators, inservice educators, and professional development personnel in the perceived effectiveness of different methods for learning technology integration skills when categorized by locus of control? All groups were measured for similarities and differences in preferences on credit classes, workshops, open computer labs, technology personnel support, peer support, online help, printed documentation, and trial and error. …

Even though information scientists generally recognize that relevance judgments are multidimensional and dynamic, there is still discussion and debate regarding the degree to which certain internal (cognition, personality) and external (situation, social relationships) factors affect the use of criteria in reaching those judgments. Much of the debate centers on the relationship of those factors to the criteria and reliable methods for measuring those relationships. This study researched the use of relevance criteria to select an information source by undergraduate students whose task it is to create a course schedule for a semester. During registration periods, when creating their semester schedules, students filled out a two-part questionnaire. After completion of the questionnaire the students completed a Myers-Briggs Type Indicator instrument in order to determine their personality type. Data was analyzed using one-way ANOVAS and Chi-Square. A positive correlation exists between personality type as expressed by the MBTI and the information source selected as most important by the subject. A correlation also exists between personality type and relevance criteria use. The correlation is stronger for some criteria than for others. Therefore, one can expect personality type to have an effect on the use of relevance criteria while selecting information sources.

A biological monitoring tool to assess water quality using bivalve gape behavior was developed and demonstrated. The purpose of this work was to develop methodologies for screening water quality appropriate to the goals of the watershed paradigm. A model of bivalve gape behavior based on prediction of behavior using autoregressive techniques was the foundation of the bivalve biomonitoring system. Current technology was used in developing the system to provide bivalve gape state data in a continuous real-time manner. A laboratory version of the system, including data collection and analysis hardware and software, was developed for use as a toxicological assay for determination of effective concentrations of toxicant(s) or other types of stress on bivalve gape behavior. Corbicula fluminea was monitored and challenged with copper, zinc, and chlorpyrifos using the system. Effective concentrations of 176±23µg/L copper, 768±412µg/L zinc, and 68µg/L chlorpyrifos were observed using a natural water with high dissolved organic carbon concentrations. A rugged field version of the bivalve biomonitoring system was developed and deployed in two locations. The field systems were fitted with a photovoltaic array, a single board computer, and a CDPD telemetry modem for robust remote operation. Data were telemetered at a time relevant rate of once …

This written thesis reveals the development of this documentary, from the pre-production to production and post-production stages. It also incorporates theoretical analysis and self-evaluation of this documentary video.

With the exception of the music of Aram Khachaturian, the output of Armenian composers has been largely overlooked. This small Middle-Eastern country with a population of almost four million and an intriguing history indeed has a rich musical heritage. From its roots in sacred music and folksong, Armenian music has evolved into a unique blend of national elements and Western art music. Although it remains largely undiscovered, there is an entire repertoire of works in this aesthetic. The Trio for clarinet, violin, and piano by Khachaturian has long been a standard in the clarinetist's repertoire. This project brings to light lesser-known works of other Armenian composers. After providing a brief history of Armenia and her music (Chapter 2), this document presents an annotated bibliography of works using the clarinet (Chapter 3). Because there are a significant number of Armenians living outside their homeland, composers considered for this bibliography include all those of Armenian descent: those born,schooled, and presently living in Armenia, as well as those born to one or both Armenian parents residing in other countries. The bibliography includes works for unaccompanied clarinet, clarinet and piano, clarinet and orchestra, and chamber music for up to seven players. Each annotation includes …

Although most institutions offer a parent program option to the orientation program, there has been little formalized research into the quality, planning or programming of parent orientation. There has been very little research into the impact parent orientation has on parents and whether or not they feel that such programs have met their needs, particularly by gender, minority status, educational background, or by geographic distance from the institution. This study seeks to determine the effectiveness of the parent orientation program at the University of North Texas to the parents who participate in this program. The study attempts to measure whether parents feel that they have adequate information about the institution to adequately support their student through the college transition; if parents feel welcomed by the UNT campus community; and if they feel that they have developed resources and institutional contacts that may be useful in the future in assisting their child to have a successful college experience at UNT. The study, conducted in the summer of 2002, had 736 respondents. An instrument developed to determine parent's perceptions of the effectiveness of the parent orientation program consisted of 31 questions using a Likert scale. A t-Test was utilized to analyze the …

The purpose of this study was to determine if there was a relationship between training in learning style adaptation and successful completion of community college courses. The rationale for conducting this study was based on the need for students to learn how to adapt their learning style in order to more effectively learn in any situation. It is also important that community colleges implement strategies that assist in student retention. The learning styles of entry-level community college students were measured using Kolb's Learning Style Inventory Version 3. Students enrolled in entry-level college courses at a small North Texas community college were studied. The Chi-square Test of Independence with a 2 x 2 design was employed. Findings indicated that there was no statistically significant difference in the relationship between students receiving training in learning styles adaptation and successful completion of entry-level college courses, and that students who attended a learning styles training session and those who did not attend a learning styles training session had an equal chance of succeeding in entry-level community college courses. Findings also indicated that students with Accommodating and Assimilating learning styles are less likely to successfully complete an entry-level college course than are students with Diverging …

Neuringer, Deiss, and Olson (2000) was replicated and extended to determine the effect of variability contingencies on task acquisition for twelve 7-9 year old children. Subjects first learned to press a computer's shift keys with increasing response variation. Each subject was then exposed to one of three experimental conditions during which they received a point for target responses. Variability condition subjects received additional points on a variable interval schedule for nontarget responses occurring less than 3% of the time. The any condition subjects received additional points on a variable interval schedule for any nontarget response. Control subjects received points only for target responses. All variability condition and two control subjects learned the target response. All any condition subjects and two control subjects did not.

This dissertation research project was conducted to investigate religion as a coping resource in later life. The major proposition of the study was that intrinsic religious orientation is positively associated with mental health in late life. A forty three-item questionnaire was distributed to residents of four independent retirement communities resulting in a sixty-six percent return rate. The convenience sample of 214 individuals, with a mean age of 81.94 years, consisted of 156 female and 58 male respondents. Intrinsic religious orientation was held as the independent variable, while mental health was the dependent variable. Stress vulnerability characteristics were held as control variables including age, gender, education, stressful life events, marital status, perceived social support, and physical health. The zero order correlation between the independent and dependent variables was r = .128, sig. = .034 (1 tailed). When all control variables were entered, the relationship between intrinsic religious orientation and mental remained, r = .116, sig. = 046 (1 tailed). Regression analysis produced three predictors of mental health for females: stressful life events, age, and intrinsic religious orientation. Intrinsic religious orientation did not significantly change the relationship between stressful life events and mental health. A highly narrow variability in the sample limited …

The thermochemistry of several species, and the kinetics of various H atom radical reactions relevant to atmospheric and combustion chemistry were investigated using ab initio theoretical techniques and the flash photolysis / resonance fluorescence technique. Using ab initio quantum mechanical calculations up to the G3 level of theory, the C-H bond strengths of several alkanes were calculated. The bond strengths were calculated using two working reactions. From the results, it is apparent that the bond strengths decrease as methyl groups are added to the central carbon. The results are in good agreement with recent experimental halogenation kinetic studies. Hydrogen bond strengths with sulfur and oxygen were studied via CCSD(T) theory, together with extrapolation to the complete basis set limit. The results for the bond dissociation energies (ground state at 0 K, units: kJ mol-1) are: S-H = 349.9, S-D = 354.7, HS-H = 376.2, DS-D = 383.4, and HO-H = 492.6. These data compare well with experimental literature. The rate constants for the isotopic reactions of H + H2S, D + H2S, H + D2S, and D + D2S are studied at the QCISD(T)/6-311+G(3df,2p) level of theory. The contributions of the exchange reaction versus abstraction are examined through transition state …

The electron emission characteristics of aluminum, molybdenum and carbon nanotubes were studied. The experiments were setup to study the emission behavior as a function of temperature and exposure to oxygen. Changes in the surface work function as a result of thermal annealing were monitored with low energy ultra-violet photoelectron spectroscopy for flat samples while field emission energy distributions were used on tip samples. The change in the field emission from fabricated single tips exposed to oxygen while in operation was measured using simultaneous Fowler-Nordheim plots and electron energy distributions. From the results a mechanism for the degradation in the emission was concluded. Thermal experiments on molybdenum and aluminum showed that these two materials can be reduced at elevated temperatures, while carbon nanotubes on the other hand show effects of oxidation. To purely reduce molybdenum a temperature in excess of 750 ºC is required. This temperature exceeds that allowed by current display device technology. Aluminum on the other hand shows reduction at a much lower temperature of at least 125 ºC; however, its extreme reactivity towards oxygen containing species produces re-oxidation. It is believed that this reduction is due to the outward diffusion of aluminum atoms through the oxide. Carbon nanotubes …

Nature aesthetics is examined as an approach to environmental ethics. The characteristics of proper nature appreciation show that every landscape can be appreciated impartially in light of the dynamic processes of nature. However, it is often claimed that natural beauty decreases if humans interfere into nature. This claim leads to the separation of human culture and nature, and limits the number of landscapes which can be protected in terms of aesthetic value. As a solution to this separation, a non-dualistic Japanese aesthetics is examined as a basis for the achievement of the coexistence of culture and nature. Ecological interrelationships between human culture and nature are possible by means of an aesthetic consciousness in terms of non-hierarchical attitudes.

This research was conducted to determine why two-year community college instructors teach over the Internet. By understanding why these instructors teach over the Internet, colleges can recruit more instructors to teach using the Web thus allowing colleges to offer more Internet courses. They can also use the information to keep the instructors who are currently teaching over the Internet satisfied, and motivate them to continue to teach. To gather this information, a questionnaire was created and evaluated for reliability and validity during a pilot study. It was then sent to those instructors who taught over the Internet, and had their e-mails available on their campus Website. A 30.5% response rate (N=100) was achieved. The survey was divided into two sections, a demographics section and a Likert scale dealing with motivation. The Likert scale had six choices ranging from strongly agree to strongly disagree and 31 statements. The demographic data were reported and summarized. The Likert items were examined using factor analysis techniques, and a number of components were discovered. Eight components, made up of the 31 variables from the Likert scale were found using the factor analysis. The eight components in order are labeled: Technical and Computer Challenges, School Promotion, …

The purpose of this thesis is to present a comprehensive colligation of applications of mobile agents in networks, and provide a baseline association of these systems. This work has been motivated by the fact that mobile agent systems have been deemed proficuous alternatives in system applications. Several mobile agent systems have been developed to provide scalable and cogent solutions in network-centric applications. This thesis examines some existing mobile agent systems in core networking areas, in particular, those of network and resource management, routing, and the provision of fault tolerance and security. The inherent features of these systems are discussed with respect to their specific functionalities. The applicability and efficacy of mobile agents are further considered in the specific areas mentioned above. Although an initial foray into a collation of this nature, the goal of this annotated bibliography is to provide a generic referential view of mobile agent systems in network applications.
