The potential of coelomocyte chemotaxis as an immune biomarker in the earthworm, Lumbricus terrestris

The potential of coelomocyte chemotaxis as an immune biomarker in the earthworm, Lumbricus terrestris

Access: Use of this item is restricted to the UNT Community.
Date: December 1999
Creator: Mota, Jennifer A.
Description: Coelomocyte migration responses, both random and chemotatic, were examined in the earthworm Lumbricus terrestris. Coelomocyte random migration patterns towards non-stimulatory, non-chemotatic solutions were described. Migration responses to immunostimulatory agents lipopolysaccharides (LPS), N-formly-methionyl-leucyl-phenylalanine (FMLP), sheep erythrocytes, Saccharomyces cerevisiae, Aeromonas hydrophila, Eisenia fetida and Rhabditis pellio were characterized. Chemotaxis was reported to LPS, FMLP, sheep erythrocytes, S. cerivesae and E. fetida. Bio-indicator potential of chemotaxis is discussed relative to variability in migration responses.

Power-benefit analysis of erasure encoding with redundant routing in sensor networks.

Power-benefit analysis of erasure encoding with redundant routing in sensor networks.

Date: December 2006
Creator: Vishwanathan, Roopa
Description: One of the problems sensor networks face is adversaries corrupting nodes along the path to the base station. One way to reduce the effect of these attacks is multipath routing. This introduces some intrusion-tolerance in the network by way of redundancy but at the cost of a higher power consumption by the sensor nodes. Erasure coding can be applied to this scenario in which the base station can receive a subset of the total data sent and reconstruct the entire message packet at its end. This thesis uses two commonly used encodings and compares their performance with respect to power consumed for unencoded data in multipath routing. It is found that using encoding with multipath routing reduces the power consumption and at the same time enables the user to send reasonably large data sizes. The experiments in this thesis were performed on the Tiny OS platform with the simulations done in TOSSIM and the power measurements were taken in PowerTOSSIM. They were performed on the simple radio model and the lossy radio model provided by Tiny OS. The lossy radio model was simulated with distances of 10 feet, 15 feet and 20 feet between nodes. It was found that by ...

The power of teams: Do self-managing work teams influence managers' perceptions of potency?

The power of teams: Do self-managing work teams influence managers' perceptions of potency?

Date: December 2005
Creator: Hass, Nicolette P.
Description: The present study examined the perceptions of teams and managers on team potency levels as a function of stage of team development. Drawing from the power and influence literature, potency was established as a means by which to assess team's internal dynamics. Stage of team development was separated into four categories including pseudo, potential, real and high performance teams. Archival data included 45 teams and managers gathered from the manufacturing and service industries. Results indicated a significant linear relationship between team perceptions of team potency and stage of team development. Additionally, potency perceptions of teams significantly differentiated between the four stages of team development. Manager perceptions of team potency produced non-significant results. Possible explanations of the results as well as implications for practice and future research are provided.

Powerlessness and the Deferred Gratification Pattern Among Lower and Middle Class Children

Powerlessness and the Deferred Gratification Pattern Among Lower and Middle Class Children

Date: August 1969
Creator: Kelley, Janette
Description: The study attempts to determine the degree of powerlessness and the deferment of gratification among children as measured by instruments designed for this purpose. An effort will be made to test whether the deferred gratification pattern exists in inverse relationship to the feeling of powerlessness among the lower classes; and to determine whether children who feel they are estranged from society have a psychological need for an impulsive release of feelings.

A Practical Approach to Donald Martino's Twelve-Tone Song Cycles: Three Songs and Two Rilke Songs, for Performance

A Practical Approach to Donald Martino's Twelve-Tone Song Cycles: Three Songs and Two Rilke Songs, for Performance

Date: May 2011
Creator: Yang, Yoon Joo.
Description: The performance of vocal works using the twelve-tone technique requires thorough study of complex rhythms, non-tonal melodies, non-traditional notations, and specific musical terms. They generally also require advanced and varied vocal techniques. Twelve-tone vocal works often contain unusual features vital to the composer's intention. One of the premiere twelve-tone composers in the United States, Donald Martino (1931-2005) composed only two solo vocal works using the twelve-tone technique: Three Songs (1955) and Two Rilke Songs (1961). He has explored innovative and progressive uses of the twelve-tone technique, and composed music with particular methods of his own, later used by other composers. Three Songs, his first twelve-tone work, and Two Rilke Songs, the only twelve-tone song cycle in his mature style, present comparable features in his use of the twelve-tone technique, text setting, and notations. The variety of ways in which Martino uses these features in the song cycles is discussed in the performance guide. The intention of the present study is to help performers, especially singers, understand Donald Martino's two twelve-tone song cycles, and to aid in the preparation of an excellent performance. The study includes a study of historical context, the poems, and Martino's compositional and aesthetic approaches to setting ...

Date: August 2012
Creator: Woodard, Chelsea S.
Description: This dissertation is a collection of poems preceded by a critical preface. The preface considers Anthony’s Hecht’s long poem, “The Venetian Vespers,” and the ways in which the temporally unsettled situation of the poem’s speaker parallels a problem facing narrative-meditative poets. The preface is divided into two main sections that explore divisions of this larger conflict. The first discusses the origins and effects of the speaker’s uprootedness in time, and the ways in which he tries to both combat and embrace this dislocation by temporarily losing himself in the immediacy of observing visual art. In this section I connect the dilemma of the speaker, who wishes to escape his memory by focusing outwards, to the dilemma of a representational poet who, despite his position towards the past, must necessarily confront or recollect memories and emotions in order to create authentic descriptions or characters. The second section focuses on the production and appreciation of artistic works (both visual and literary) and how the meaning, production and appreciation of beauty are inseparable from its existence within the physical limits of time. Here I discuss the significance of Hecht’s character who is surrounded with beauty yet describes himself as a person who only ...

The Practice and Procedures of Broadcasting for the Play-by-play Sports Announcer

The Practice and Procedures of Broadcasting for the Play-by-play Sports Announcer

Date: August 1966
Creator: Mercer, William A.
Description: The problem is twofold. There have been short chapters on sports announcing included in most broadcasting textbooks. These chapters have given a limited, cursory explanation of the preparation necessary for aspiring sportscasters. Secondly, most authors have approached the field from the viewpoint of the researcher. This investigation approaches the problem from the viewpoint of a sports announcer who has started in small market radio and worked his way through to a responsible position in a major broadcasting area.

Practices and attitudes toward alternative medicine among college students.

Practices and attitudes toward alternative medicine among college students.

Access: Use of this item is restricted to the UNT Community.
Date: December 2001
Creator: Fogle, Peggy
Description: This study assesses practices of college students (N=913) toward alternative medicine, relationships of students' health locus of control with practices of alternative medicine, and relationships of students' attitudes toward alternative medicine and health locus of control. A principal components factor analysis established construct validity of the author-designed Attitude Toward Alternative Medicine Scale, extracting three factors: Holistic Attitude/Control, Safety, and Satisfaction. Holistic Attitude/Control predicted use of alternative medicine (Wald =61.9, p < .01). A principal components factor analysis established construct validity of the Multidimensional Health Locus of Control Scale, extracting three factors: Internal Health Locus of Control, External-Chance, and External-Powerful Others. Internal Health Locus of Control significantly correlated with Holistic Attitude/Control (r = .35, p =.01).
