The Nonadditive Generalization of Klimontovich's S-Theorem for Open Systems and Boltzmann's Orthodes

The Nonadditive Generalization of Klimontovich's S-Theorem for Open Systems and Boltzmann's Orthodes

Date: August 2008
Creator: Bagci, Gokhan Baris
Description: We show that the nonadditive open systems can be studied in a consistent manner by using a generalized version of S-theorem. This new generalized S-theorem can further be considered as an indication of self-organization in nonadditive open systems as prescribed by Haken. The nonadditive S-theorem is then illustrated by using the modified Van der Pol oscillator. Finally, Tsallis entropy as an equilibrium entropy is studied by using Boltzmann's method of orthodes. This part of dissertation shows that Tsallis ensemble is on equal footing with the microcanonical, canonical and grand canonical ensembles. However, the associated entropy turns out to be Renyi entropy.

Noncovalent crosslinking of SH1 and SH2 to detect dynamic flexibility of the SH1 helix

Noncovalent crosslinking of SH1 and SH2 to detect dynamic flexibility of the SH1 helix

Date: August 2000
Creator: Park, Hyunguk
Description: In this experiment, fluorescent N- (1-pyrenyl) iodoacetamide modified the two reactive thiols, SH1 (Cys 707) and SH2 (Cys 697) on myosin to detect SH1-SH2 a -helix melting. The excimer forming property of pyrene is well suited to monitor the dynamics of the SH1 and SH2 helix melting, since the excimer should only form during the melted state. Decreased anisotropy of the excimer relative to the monomeric pyrene fluorescence is consistent with the disordering of the melted SH1-SH2 region in the atomic model. Furthermore, nucleotide analogs induced changes in the anisotropy of the excimer, suggesting that the nucleotide site modulates the flexibility of SH1-SH2 region.

Nondirective Group Play Therapy with Aggressive Boys

Nondirective Group Play Therapy with Aggressive Boys

Date: August 1970
Creator: Bucur, Raymond R.
Description: The study reported here attempts to demonstrate the utility of group play therapy as a method of reducing aggression in preadolescent aged boys. Previous research has attempted to demonstrate the value of play therapy as a method of dealing with a variety of emotional and behavioral problems.

Nonlinear UV Laser Build-up Cavity: An Efficient Design

Nonlinear UV Laser Build-up Cavity: An Efficient Design

Date: May 2009
Creator: Rady, Nicholas Henry
Description: Using the concept of the build-up cavity for second harmonic generation to produce 243nm laser light, an innovative cavity is theoretically explored using a 15mm length CLBO crystal. In order to limit the losses of the cavity, the number of effective optical surfaces is kept to only four and the use of a MgF2 crystal is adopted to separate the harmonic and fundamental laser beam from each other. The cavity is shown to have an expected round trip loss of five tenths of a percent or better, resulting in a conversion efficiency greater than 65%.

Nonparametric Estimation of Receiver Operating Characteristic Surfaces Via Bernstein Polynomials

Nonparametric Estimation of Receiver Operating Characteristic Surfaces Via Bernstein Polynomials

Access: Use of this item is restricted to the UNT Community.
Date: December 2012
Creator: Herath, Dushanthi N.
Description: Receiver operating characteristic (ROC) analysis is one of the most widely used methods in evaluating the accuracy of a classification method. It is used in many areas of decision making such as radiology, cardiology, machine learning as well as many other areas of medical sciences. The dissertation proposes a novel nonparametric estimation method of the ROC surface for the three-class classification problem via Bernstein polynomials. The proposed ROC surface estimator is shown to be uniformly consistent for estimating the true ROC surface. In addition, it is shown that the map from which the proposed estimator is constructed is Hadamard differentiable. The proposed ROC surface estimator is also demonstrated to lead to the explicit expression for the estimated volume under the ROC surface . Moreover, the exact mean squared error of the volume estimator is derived and some related results for the mean integrated squared error are also obtained. To assess the performance and accuracy of the proposed ROC and volume estimators, Monte-Carlo simulations are conducted. Finally, the method is applied to the analysis of two real data sets.

Nontraditional name changes for men: Attitudes of men and women.

Nontraditional name changes for men: Attitudes of men and women.

Date: May 2008
Creator: Millspaugh, Jennifer Diane
Description: Recently, some men have taken their wives' last names upon marriage rather than following tradition. The goal of this study was to examine the attitudes that men and women have toward these nontraditional men. Ideological hegemony and social identity theory comprised the framework for examining participants' beliefs. A survey first elicited participants' extant sexist beliefs about men and the characteristics of a nontraditional man compared to a traditional man. An open-ended question further explored participants' opinions. The results indicated that benevolent sexism influences respondents' attitudes towards nontraditional men and that most respondents view nontraditional men as more nurturing and committed to their marriage than traditional men. The results further revealed a dichotomy of positive and negative attitudes towards nontraditional men indicating that society's feelings about nontraditional men are changing.

Nontraditional students in community colleges and the model of college outcomes for adults.

Nontraditional students in community colleges and the model of college outcomes for adults.

Date: December 2005
Creator: Philibert, Nanette
Description: The purpose of this study was to examine three components of Donaldson and Graham's (1999) model of college outcomes for adults: (a) Prior Experience & Personal Biographies, (b) the Connecting Classroom, and (c) Life-World Environment, and to assess their application to traditional and nontraditional students in community colleges in both technical and nontechnical courses. The study sample was comprised of 311 community college students enrolled in technical and nontechnical courses during fall 2005. A survey instrument was developed based on the three model components through a review of the literature. Demographic data collected were utilized to classify students into a technical or nontechnical grouping as well as four classifications of traditionalism: (a) traditional, (b) minimally nontraditional, (c) moderately nontraditional, and (d) highly traditional. This study found that nontraditional students vary from traditional students in regards to the three model constructs. A post hoc descriptive discriminate analysis determined that the Life-World Environment component contributed the most to group differences with the minimally nontraditional group scoring the highest on this construct.

Nopalita: A Mythology of Cultural Self-Representation

Nopalita: A Mythology of Cultural Self-Representation

Date: August 2004
Creator: Medina, Cristina Blasa
Description: The first segment introduces the background information on the use of paƱos as art by prisoners and how I appropriate the same materials to create and record my own cultural mythology. The Statement of Problem and Questions are about how and what cultural information is chosen in creating a visual mythology. The second segment explains the invention of the mythology by describing why certain experiences were chosen, specifically those of the graduate school experience. Also the development of self-representation through self-portraits is described. The third segment explains the symbolism used in the imagery, such as the cacti as cultural indicator and palimpsest. The fourth segment is a conclusion involving the realization that feeling caught within a hybrid culture is an important part of my identity.

North American Indian Mythology and Folklore for Secondary School Students

North American Indian Mythology and Folklore for Secondary School Students

Date: January 1970
Creator: Jackson, Sarah
Description: Through a study of North American Indian folklore and mythology, the non-Indian can at last begin to know the Indian with whom he has shared a continent and to find out something of his religion, traditions, history, humor, and tribal peculiarities. The approach to this study through motifs, already familiar to the students from other literature, offers a practical approach and one that can be adapted to classroom use, perhaps either in the study of myth, the study of literary types, the study of literature per se, or perhaps in the study of cultural differences.
