Mouse cortical cholinergic neurons: Ontogeny of phenotypes in vivo and in vitro.

Mouse cortical cholinergic neurons: Ontogeny of phenotypes in vivo and in vitro.

Date: August 2005
Creator: Coiculescu, Olivia Elena
Description: The development of cholinergic neurons in mouse frontal cortex was studied both in vivo and in vitro by immunocytochemistry with an antibody to choline acetyltransferase (ChAT), the enzyme responsible for acetylcholine synthesis. While cortical cholinergic neurons have previously been characterized in rat cortex, up until very recently, intrinsic cortical cholinergic neurons were considered to be absent in mouse, and little is known about their development or phenotypic characteristics. The present study found no ChAT-positive neurons in mouse frontal cortex on postnatal day 0 (P0, the day of birth). On P7 there were few, faintly stained, ChAT-positive neurons. The numerical density of ChAT-positive neurons increased substantially with age, from none on P0, to 9.2 + 1.4 on P7, to 14.8 + 0.9 on P16, and 41.6 + 3.9 in adulthood. Considering that the numerical density of total neurons decreases during this postnatal period, the data represent a marked developmental increase in the percentage of cholinergic neurons. The development of cholinergic neurons showed very similar timelines in rat and mouse frontal cortex. Cultures prepared from mouse frontal cortex on embryonic day 16 were maintained for 25, 76, or 100 days in vitro (div). The percentage of ChAT-positive neurons was considerably higher than ...

Moving in a New Direction: An Exploration in Kinetics

Moving in a New Direction: An Exploration in Kinetics

Date: August 2004
Creator: Illy, Etienne
Description: Movement, whether conveyed through an actual motion or a gestured implication, remains an underlying theme in my creative process that started with my earliest works. I explored different aspects of kinetic sculpture, because I am seeking new ways to create motion such as experimenting with circulating air, wind, and the use of water features. I created a series consisting of three to five kinetic sculptures which do not rely on sound or direct viewer manipulation.

Moving toward the 21st Century: American Association of Colleges of Nursing Guidelines and Baccalaureate Nursing Education

Moving toward the 21st Century: American Association of Colleges of Nursing Guidelines and Baccalaureate Nursing Education

Date: August 1998
Creator: Bruner, Jeanne K.
Description: This study investigated current use of American Association of Colleges of Nursing guidelines in preparing the baccalaureate nurse graduate to practice nursing in the community health sector of the healthcare delivery system and use of community based healthcare delivery sites by baccalaureate programs located in non-urbanized and urbanized areas. The extent of guidelines adoption, plans by colleges not currently using them to do so in the future, and impact of accreditation visits on the adoption of the guidelines were also explored. A qualitative survey design was used to describe the use of AACN guidelines in the development of baccalaureate nursing education.

Mozartean Gesture and Rhetoric in Hummel's Concerto for Trumpet

Mozartean Gesture and Rhetoric in Hummel's Concerto for Trumpet

Date: May 2008
Creator: Phillips, Edward
Description: Hummel's Concerto for Trumpet (Concerto a Tromba principale) is overtly operatic and is stylistically reminiscent of Mozart's Don Giovanni. Using the methodology of Leonard Ratner and Wye J. Allanbrook, it is possible to explore gesture and rhetoric in Hummel's Concerto for Trumpet and Mozart's Don Giovanni, and achieve a deeper understanding of the stylistic similarities shared between the two works. In the third movement, dance is the most significant link to Don Giovanni. In the second movement, Hummel alternates between the emotions of Donna Anna and Don Ottavio as they appear in act 1, scene 13. The first movement makes extensive use of contrasting topics identified with buffa and seria characters to advance the musical narrative. Comparing Hummel's concerto and Mozart's opera is a hermeneutical approach that illuminates several performance practice implications. Knowing the expressive similarities and rhetorical strategies common to both works clarifies several issues, such as tempo, ornamentation, and above all, expression. Though Mozart's Don Giovanni and Hummel's Concerto for Trumpet are unequal in significance, it would be valuable to any interpretation of Hummel's concerto if the performer and audience acknowledge that the work is rhetorically and stylistically similar to Mozart's Don Giovanni.

Mr Secrets and Social Media:  the Confession of Richard Rodriguez

Mr Secrets and Social Media: the Confession of Richard Rodriguez

Date: May 2013
Creator: Burns, Amanda Jill
Description: Richard Rodriguez's works create troubling situations for many scholars. Though numerous critics see him as the penultimate Chicano writer, many others see his writing as only pandering to the elite. However, all politics and controversies aside, he is a writer whose ideas upon language and public confession have been revolutionary. Throughout the thesis, I argue that Rodriguez's ideas upon language and identity are applicable to the social media landscape that we reside in currently, especially the public confession. Also, I use deconstructionism, along with postmodern criticism, to illustrate the changing arc of Rodriguez's confession from his first autobiography to his final one. In his first memoir, Rodriguez remains in the closet upon his sexuality, and the reader only catches glimpses of the 'real' character inside his work. In the second memoir, the reader sees a better glimpse because of his coming out; yet, even in this regard, he does not do so wholly and still leaves his confession unfinished. By the third, he applies themes and problems seen in his first and second works to discuss our browning nature, and how we are all sinners and that we desire to confess our sins. In my assessment of Rodriguez, I argue ...

Muerte Y Soledad En La Poesía De Manuel Altolaguirre Ante El Exilio

Muerte Y Soledad En La Poesía De Manuel Altolaguirre Ante El Exilio

Date: May 2013
Creator: Mandujano, Olga Lidia
Description: This study focuses on the Spanish poet of the Generation of '27 Manuel Altolaguirre. The purpose of this thesis is to show how the poetry of Manuel Altolaguirre evolves in relation to specific issues. Specifically, I study the changes in his work in regard to the themes of death and solitude, resulting from exile in 1939, to be enriched by new experiences, many of them dramatic, taking more personal ways, while offering them a more profound and complex and even in regard to the subject of the poet's death comes to contemplate a more positive way. The thesis is divided into five chapters. Following the introduction, the second chapter focuses on Altolaguirre's biography and the Generation in 1927 while the third focuses and analyzes his poetry before his exile in 1939. The fourth chapter examines his poetry after exile until his death in 1959, while the fifth and last chapter concludes this study.

Access: Use of this item is restricted to the UNT Community.
Date: August 2000
Creator: Gollapally, Devender R.
Description: The World Wide Web is one of the largest sources of information; more and more applications are being developed daily to make use of this information. This thesis presents a multi-agent architecture that deals with some of the issues related to Internet data extraction. The primary issue addresses the reliable, efficient and quick extraction of data through the use of HTTP performance monitoring agents. A second issue focuses on how to make use of available data to take decisions and alert the user when there is change in data; this is done with the help of user agents that are equipped with a Defeasible reasoning interpreter. An additional issue is the visualization of extracted data; this is done with the aid of VRML visualization agents. The cited issues are discussed using stock portfolio management as an example application.

Multi-Channel Retailing: Function of Consumers' Perceived Benefits and Costs and Retail Synergy

Multi-Channel Retailing: Function of Consumers' Perceived Benefits and Costs and Retail Synergy

Date: May 2003
Creator: Pookulangara, Sanjukta Arun
Description: This study investigated the consumers' intention towards multi-channel shopping and the function of synergy in a multi-channel retailing format (i.e., brick-and-mortar stores, catalogs, and the Internet). Two questionnaires were developed, one for the multi-channel consumers and the other for the multi-channel retailers. The structural equation modeling was used to predict the effect of shopping benefits and costs perceived from each channel on the consumer's purchase intention. Data analysis (N = 500) indicated that the purchase intentions were affected by different shopping benefit and cost variables. Qualitative analysis of retailers (N= 10) revealed that the retailers considered synergy to be an important part of their multi-channels. Also, there existed a high level of synergy among the existing three retail channels.

A multi-dimensional entropy model of jazz improvisation for music information retrieval.

A multi-dimensional entropy model of jazz improvisation for music information retrieval.

Date: December 2005
Creator: Simon, Scott J.
Description: Jazz improvisation provides a case context for examining information in music; entropy provides a means for representing music for retrieval. Entropy measures are shown to distinguish between different improvisations on the same theme, thus demonstrating their potential for representing jazz information for analysis and retrieval. The calculated entropy measures are calibrated against human representation by means of a case study of an advanced jazz improvisation course, in which synonyms for "entropy" are frequently used by the instructor. The data sets are examined for insights in music information retrieval, music information behavior, and music representation.
