An investigation of the relationships between job characteristics, satisfaction, and team commitment as influenced by organization-based self-esteem within a team-based environment

An investigation of the relationships between job characteristics, satisfaction, and team commitment as influenced by organization-based self-esteem within a team-based environment

Date: August 2000
Creator: Abbott, John B.
Description: Team-based management is a popular contemporary method of redesigning jobs in order to more effectively utilize the human potential of employees. The use of such management techniques should result in increased satisfaction and team commitment; however, many research studies have failed to demonstrate increases in affective outcomes on the part of the employee. The research question examined in this study is, "What specific job dimensions and situational factors result in higher levels of satisfaction and team commitment?" The Job Characteristics Model (Hackman & Oldham, 1975) provided a basis for this study. The model was designed for individual contributors and has not been extensively used in team research. As expected it was found that within a team-based environment higher levels of the five core job dimensions of skill variety, task identity, task significance, autonomy, and job feedback were associated with increased satisfaction and team commitment. Organization-based self-esteem was found to mediate the relationship between the five core job dimensions and the affective outcome variables. Contrary to expectations, however, it was found that consultative team members experienced higher levels of satisfaction and commitment than substantive team members. In addition, consultative team members reported higher levels of two core job dimensions, skill variety ...

The Meaning of Elder Abuse

The Meaning of Elder Abuse

Access: Use of this item is restricted to the UNT Community.
Date: May 2000
Creator: Achilli, Raye
Description: Elder abuse first received national attention in 1980, as the subject of a congressional investigation. Now, 20 years later, establishing successful strategies of identification, subsequent intervention, and prevention of abuse is of paramount importance; but progress toward this goal is hindered by lack of consensus as to the definition of elder abuse, and the use of vague, confusing, and sometimes contradictory terms in its discussion. In this paper, both social research and professional approaches and legal approaches to the definition of elder abuse are surveyed, as are definitions formulated for the National Elder Abuse Incidence Study conducted by the National Center on Elder Abuse. The continuing need for a universal or standard definition is emphasized.

An analysis of the Sonata for Trumpet and Piano by Peter Maxwell Davies, identifying the use of historical forms, and the implications for performance.

An analysis of the Sonata for Trumpet and Piano by Peter Maxwell Davies, identifying the use of historical forms, and the implications for performance.

Access: Use of this item is restricted to the UNT Community.
Date: August 2006
Creator: Adduci, Kathryn James
Description: The Sonata for Trumpet and Piano by Peter Maxwell Davies is one of his earliest works, and a notoriously difficult work to perform. While using serialism and other twentieth-century compositional techniques, this work also uses older historical forms, including sonata-allegro and sonata-rondo forms. An analysis of the work is presented, identifying the older historical forms, and considerations for performers when making decisions on how to perform the work are provided.

Creator: Akinola, Adeniyi O.
Description: Baeyer-Villiger oxidation of 1,9-dibromopentacyclo[5.4.0.02,6.03,10.05,9]undecane-8,11-dione (1,9-dibromo-PCU-8,11-dione) was performed by using an excess amount of m-chloroperbenzoic acid (3 equivalents) and resulted in the formation of the corresponding monolactone. The reaction would not proceed to the dilactone stage. The structure of the reaction product was established unequivocally via single crystal X-ray diffraction. Baeyer-Villiger oxidation of 1,9-dibromo-PCU-8,11-dione using ceric ammonium nitrate (CAN) was also performed and afforded a mixture of lactones. Only one of these lactones, which also contained an alkene functionality, could be isolated and characterized. 1,7-dibromo-PCU-8,11-dione was also reacted with CAN, yielding the mono-lactone, which has also been characterized.

Development of a procedure to evaluate groundwater quality and potential sources of contamination in the East Texas Basin

Development of a procedure to evaluate groundwater quality and potential sources of contamination in the East Texas Basin

Access: Use of this item is restricted to the UNT Community.
Date: May 2001
Creator: Alderman, John H.
Description: This study contributes a procedure, based on data analysis and geostatistical methods, to evaluate the distribution of chemical ratios and differentiate natural and anthropogenic contaminant sources of groundwater quality in the East Texas Basin. Four aquifers were studied, Sparta, Queen City, Carrizo and Wilcox. In this study, Carrizo- Wilcox is considered as one aquifer, and Sparta-Queen City as another. These aquifers were divided into depth categories, 0-150 feet for Sparta-Queen City and 300-600 feet and 600-900 feet for Carrizo-Wilcox in order to identify individual sources of contamination. Natural sources include aquifer mineral make up, salt domes and lignite beds. Major anthropogenic sources include lignite and salt dome mining and oil-gas production. Chemical ratios selected were Na/Cl, Ca/Cl, Mg/Cl, SO4/Cl, (Na+Cl)/TDS, SO4/Ca and (Ca+Mg)/(Na+K). Ratio distributions and their relationships were examined to evaluate physical-chemical processes occurring in the study area. Potential contaminant sources were used to divide the Basin into three areas: Area 1 to the east, Area 2 in the west and Area 3 in the center. Bivariate analysis was used to uncover differences between the areas. The waters in Area 1 are potentially impacted primarily from oil field waters. Sources present in Area 2 include lignite beds and oil ...

Comparison and Evaluation of Existing Analog Circuit Simulator using Sigma-Delta Modulator

Access: Use of this item is restricted to the UNT Community.
Date: December 2006
Creator: Ale, Anil Kumar
Description: In the world of VLSI (very large scale integration) technology, there are many different types of circuit simulators that are used to design and predict the circuit behavior before actual fabrication of the circuit. In this thesis, I compared and evaluated existing circuit simulators by considering standard benchmark circuits. The circuit simulators which I evaluated and explored are Ngspice, Tclspice, Winspice (open source) and Spectre® (commercial). I also tested standard benchmarks using these circuit simulators and compared their outputs. The simulators are evaluated using design metrics in order to quantify their performance and identify efficient circuit simulators. In addition, I designed a sigma-delta modulator and its individual components using the analog behavioral language Verilog-A. Initially, I performed simulations of individual components of the sigma-delta modulator and later of the whole system. Finally, CMOS (complementary metal-oxide semiconductor) transistor-level circuits were designed for the differential amplifier, operational amplifier and comparator of the modulator.

Emotional Health, Well-Being, And Religion as Quest

Emotional Health, Well-Being, And Religion as Quest

Access: Use of this item is restricted to the UNT Community.
Date: August 2000
Creator: Alexander, Kimberly A.
Description: This study examined the relationship between the religious orientation quest and well-being using the 1998 General Social Survey. In addition to the religious orientation quest the extrinsic and intrinsic religious orientations were also investigated. Analysis of the data indicated that there was a slight negative association between quest and general well-being, while also demonstrating a strong positive association between quest and inner peace. These results underscore the supposition that quest is an orientation that is complex and ultimately deserves further attention.

Iconoclast in the mirror.

Iconoclast in the mirror.

Access: Use of this item is restricted to the UNT Community.
Date: August 2005
Creator: Alexander, Lydia L.
Description: This work explores identity positions of speakers in modern and contemporary poetry with respect to themes of subjectivity, self-awareness, lyricism, heteroglossia, and social contextualization, from perspectives including Bakhtinian, queer, feminist and postructuralist theories, and Peircian semiotics. Tony Hoagland, W.H. Auden, Adrienne Rich, and the poetic prose of Hélène Cixous provide textual examples of an evolving aesthetic in which the poet's self and world comprise multiple dynamic, open relationships supplanting one in which simple correspondences between signifiers and signifieds define selves isolated from the world. Hypertext and polyamory serve as useful analogies to the semantic eros characteristic of such poetry, including the collection of original poems that the critical portion of this thesis introduces.

An Examination of Methodological Rigor and Its Effects on Organizational Development and Change Outcomes

An Examination of Methodological Rigor and Its Effects on Organizational Development and Change Outcomes

Access: Use of this item is restricted to the UNT Community.
Date: May 2005
Creator: Alexander, Sandra G.
Description: Organizational development and change (ODC) is a broad field because change occurs in all organizations, occurs at multiple organizational levels, consists of numerous interventions, and can impact multiple outcomes. Many ODC efforts attempt to examine the effectiveness of their initiatives, yet fail to account for the quality, or rigor of their methods. The purpose of this paper is to examine how methodological rigor and intervention implementation quality impact ODC outcomes. The results indicate that overall methodological rigor is not a significant predictor of organizational change outcomes; however, several individual rigor criteria exhibit predictive power. Implementation quality is a significant predictor of organizational outcomes, but in a negative direction.
