The Effects of a Kindergarten-First Grade Looping Program on Academic Achievement and Self-Esteem

The Effects of a Kindergarten-First Grade Looping Program on Academic Achievement and Self-Esteem

Date: December 2002
Creator: Murphy, Doris Jo
Description: The purpose of this study was to determine if academic achievement and academic self-esteem can be linked to the non-traditional organizational pattern of looping in kindergarten and first grade classes. Looping is defined as one teacher remaining with the same students for two or more years. Using a control group-experimental group design where the experimental group participated in the looping program and the control group did not, and applying the statistical procedure of multivariate analysis of variance (MANAVO), it was found that there was no significant difference between the subjects in the two groups on the criterion variable of academic achievement as measured by the Iowa Test of Basic Skills, and the criterion variable of academic self-esteem as measured by the Culture-Free Self-Esteem Inventory, Second Edition. It was concluded that further study would need to be done to determine if there are advantages to an organizational pattern of looping for students in public elementary schools.

The effects of reinforcing operant variability on task acquisition.

The effects of reinforcing operant variability on task acquisition.

Access: Use of this item is restricted to the UNT Community.
Date: December 2002
Creator: Seymour, Kail H.
Description: 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.

The Electron Emission Characteristics of Aluminum, Molybdenum and Carbon Nanotubes Studied by Field Emission and Photoemission.

The Electron Emission Characteristics of Aluminum, Molybdenum and Carbon Nanotubes Studied by Field Emission and Photoemission.

Date: December 2002
Creator: Sosa, Edward Delarosa
Description: 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 ...

Emergency Physician Communication Style and Career Satisfaction: Is There a Correlation?

Emergency Physician Communication Style and Career Satisfaction: Is There a Correlation?

Date: December 2002
Creator: McEwen, Janet S.
Description: The correlation between social style and career satisfaction among emergency physicians was investigated. An e-mail survey was sent to a random sample of 1,000 members of the American College of Emergency Physicians in practice for at least three years; 707 had valid e-mail addresses. A twenty-item behavioral style survey instrument and a five-item career satisfaction scale were used. The study incorporated prenotification and reminder e-mails. Valid responses were obtained from 329 physicians (46.5%). No correlation was shown between social style and career satisfaction. Problems with both survey instruments were discovered. Survey respondents were unhappy with their careers, with an average satisfaction of 4.03, 1 being very satisfied, 5 very dissatisfied. Areas for future study include redoing the study using different survey instruments.

Ensuring Authenticity and Integrity of Critical Information Using XML Digital Signatures

Ensuring Authenticity and Integrity of Critical Information Using XML Digital Signatures

Access: Use of this item is restricted to the UNT Community.
Date: December 2002
Creator: Korivi, Arjun
Description: It has been noticed in the past five years that the Internet use has been troubled by the lack of sufficient security and a legal framework to enable electronic commerce to flourish. Despite these shortcomings, governments, businesses and individuals are using the Internet more often as an inexpensive and ubiquitous means to disseminate and obtain information, goods and services. The Internet is insecure -- potentially millions of people have access, and "hackers" can intercept anything traveling over the wire. There is no way to make it a secure environment; it is, after all, a public network, hence the availability and affordability. In order for it to serve our purposes as a vehicle for legally binding transactions, efforts must be directed at securing the message itself, as opposed to the transport mechanism. Digital signatures have been evolved in the recent years as the best tool for ensuring the authenticity and integrity of critical information in the so called "paperless office". A model using XML digital signatures is developed and the level of security provided by this model in the real world scenario is outlined.

Eplucher Les Oignons (Peeling the Onions)

Eplucher Les Oignons (Peeling the Onions)

Date: December 2002
Creator: Wester, Judith C.
Description: My creative intent is to connect with viewers at an emotional level. My chosen metaphor is “Peeling the Onion.” The implication of the metaphor is that understanding is achieved after one looks below the surface and views the underlying “layers.” The challenge is to find images that are personally interesting and also connect with the viewer. At times the creative process proceeds in linear manner and at other times it seems to take on a life of its own. During my search for a balance between the literal and ambiguous, I explored the circle, the spiral and the sphere. Printmaking offers unique opportunities to produce evocative imagery. Drawing is the basic tool I employ to define form and my use of printmaking processes allows for evolving the image over time. The immediacy and spontaneity of my drawings is combined with a methodical approach to image development. Exploring the spiral, sphere, circles and the metaphor “Peeling the Onion” has provided me a means of giving a form to my concepts and hopefully a connection with the viewer.

An Evaluation of the Effects of a Pay for Performance Plan on Productivity of Employees of a Professional Services Firm

An Evaluation of the Effects of a Pay for Performance Plan on Productivity of Employees of a Professional Services Firm

Date: December 2002
Creator: Porter, Melanie
Description: 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.

An Examination of American Sideshow Banners as Folk Art, ca. 1920-1960

An Examination of American Sideshow Banners as Folk Art, ca. 1920-1960

Date: December 2002
Creator: Weimer, Emery Christian
Description: This thesis redresses the lack of scholarly attention paid to painted circus banners produced in the United States during the first half of the twentieth century by exploring the extent to which American folk art painting scholarship, methodologies, and objects can be used to articulate the meaning and significance of banner painting. This study expands the disciplinary treatment of banner painting by introducing domesticated art as a means of representing non-academic art produced in the U.S. The thesis also presents a model for exploring banner painting after identifying traditional American folk art painting methodologies, which fail to investigate banner painting style, format, and artistic training associated with banner work.

The Exploration of Surface and Texture on the Inside and Outside of My Sculpture

The Exploration of Surface and Texture on the Inside and Outside of My Sculpture

Date: December 2002
Creator: Holt, John
Description: After generating work for many years in an intuitive, “truth to materials” mindset my intent was to explore the interior possibilities of my sculptural forms and relate these if possible, to the exterior. Alongside this exploration of the interior I introduced surface texture and color onto both interior/exterior surfaces. In some cases the work had undergone a change, which lent new meaning and provided new relationships to exist between the interior/exterior of my sculpture. Not all of the work was satisfactory to me, though I feel there were many positive results from work that may not have been successful. I found that the integration of the interior/exterior dialogue into my existing work provided new meaning allowing new relationships within the work that had not existed previously.

Faculty Practice Among Commission of Collegiate Nursing Education Accredited Nursing Schools

Faculty Practice Among Commission of Collegiate Nursing Education Accredited Nursing Schools

Date: December 2002
Creator: Roberts, Amy
Description: 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 ...
