Synthesis of the Personal and the Political in the Works of May Stevens

Synthesis of the Personal and the Political in the Works of May Stevens

Date: May 1998
Creator: Abbott, Janet Gail
Description: This thesis is an investigation of the way in which the painter May Stevens (b. 1924) synthesizes her personal experiences and political philosophy to form complex and enduring works of art. Primary data was accumulated through an extended interview with May Stevens and by examining her works on exhibit in New York and Boston. An analysis of selected works from her "Big Daddy" and "Ordinary/Extraordinary" series revealed how her personal feelings about her own family became entwined with larger political issues. As an important member of the feminist art movement that evolved during the 1970s, she celebrated this new kinship among women in paintings that also explored the contradictions in their lives. In more recent work she has explored complex social issues such as teenage prostitution, sexism, and child abuse in a variety of artistic styles and media. This study investigates how May Stevens continues to portray issues of international significance in works that consistently engage the viewer on a personal, almost visceral level.

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 ...

Biodiversity of Dragonflies and Damselflies (Odonata) of the South-Central Nearctic and Adjacent Neotropical Biotic Provinces

Biodiversity of Dragonflies and Damselflies (Odonata) of the South-Central Nearctic and Adjacent Neotropical Biotic Provinces

Date: May 1999
Creator: Abbott, John C.
Description: The south-central United States serves as an important biogeographical link and dispersal corridor between Nearctic and Neotropical elements of western hemisphere odonate faunas. Its species are reasonably well known because of substantial collections, but there has been no concerted effort to document the extent of biodiversity and possible geographic affinities of dragonflies and damselflies of this region. The recent discoveries of Argia leonorae Garrison, Gomphus gonzalezi Dunkle and Erpetogomphus heterodon Garrison from southern and western Texas and northern Mexico suggest that Odonata species remain to be discovered in this area, particularly from far south Texas and northern Mexico. I have documented a total of 12,515 records of Odonata found in 408 counties within the south-central U.S. A total of 73 species of damselflies and 160 species of dragonflies was revealed in the region. The 233 (197 in Texas) Odonata species are distributed among 10 families and 66 genera. Illustrated family, generic, and species-level keys are provided. Since the beginning of this work in the Fall of 1993, one species has been added each to the Louisiana and Oklahoma faunas, and 12 species have been added, previously unreported from Texas, including four new to the U.S. The area of highest Odonata ...

The Effect of Average Grain Size on Polycrystalline Diamond Films

The Effect of Average Grain Size on Polycrystalline Diamond Films

Date: May 2002
Creator: Abbott, Patrick Roland
Description: The work function of hydrogen-terminated, polycrystalline diamond was studied using ultraviolet photoelectron spectroscopy. Polycrystalline diamond films were deposited onto molybdenum substrates by electrophoresis for grain sizes ranging from 0.3 to 108 microns. The work function and electron affinity were measured using 21.2 eV photons from a helium plasma source. The films were characterized by x-ray photoelectron spectroscopy to determine elemental composition and the sp2/sp3 carbon fraction. The percentage of (111) diamond was determined by x-ray diffraction, and scanning electron microscopy was performed to determine average grain size. The measured work function has a maximum of 5.1 eV at 0.3 microns, and decreases to 3.2 eV at approximately 4 microns. Then the work function increases with increasing grain size to 4.0 eV at 15 microns and then asymptotically approaches the 4.8 eV work function of single crystal diamond at 108 microns. These results are consistent with a 3-component model in which the work function is controlled by single-crystal (111) diamond at larger grain sizes, graphitic carbon at smaller grain sizes, and by the electron affinity for the intervening grain sizes.

My Whine, Your Wine

My Whine, Your Wine

Date: December 2011
Creator: Abbott, Shannon Marie
Description: Grapes hold the flavors of the lands where they grow, and when you make wine from them, those flavors of the land come through. Tasting wine from a place you've been can bring you back to that place with aromas and notes indicative of that place. A bottle of wine changes every day, and how it will taste depends on the moment you choose to release it from the glass walls. I have a vested interest in wine, because it is a living thing. I am compelled to make wine because its characteristics are like personality traits. Although some of those characteristics are harsh at times, I appreciate them all. Each trait plays an important role in the balance, the overall personality. Like my own personality flaws, wine's harsh tones can smooth over time. My relationship with wine is constantly evolving, with every new varietal, vintage, batch and blend. Believe me, after some of the jobs I had before my first day at Su Vino, I cherish every moment of my winemaking career. My Whine, Your Wine is the story of how it all started.

Landscape forest modeling of the Luquillo Experimental Forest, Puerto Rico.

Landscape forest modeling of the Luquillo Experimental Forest, Puerto Rico.

Date: December 2002
Creator: Abbott-Wood, Chris
Description: This thesis contributes to modeling the dynamics of forest community response to environmental gradients and disturbances over a mountain landscape. A gap model (FACET) was parameterized for species of various forest types (Tabonuco, Colorado, Dwarf and Palm), for many terrain conditions and was modified and extended to include species response to excess soil moisture and hurricanes. Landscape cover types were defined by dominance of species of each forest type and canopy height. Parameters of the landscape model (MOSAIC) were calculated from multiple runs of FACET. These runs were determined by combining terrain variables (elevation and soil) and hurricane risk. MOSAIC runs were analyzed for distribution patterns. Geographic Information Systems software was used to process terrain variables, hurricane risk and MOSAIC model output.

Interfacial Characterization of Chemical Vapor Deposition (Cvd) Grown Graphene and Electrodeposited Bismuth on Ruthenium Surface

Interfacial Characterization of Chemical Vapor Deposition (Cvd) Grown Graphene and Electrodeposited Bismuth on Ruthenium Surface

Date: May 2014
Creator: Abdelghani, Jafar
Description: Graphene receives enormous attention owing to its distinctive physical and chemical prosperities. Growing and transferring graphene to different substrates have been investigated. The graphene growing on the copper substrate has an advantage of low solubility of carbon on the copper which allow us to grow mostly monolayer graphene. Graphene sheet of few centimeters can be transferred to 300nm silicon oxide and quartz crystal pre-deposited with metal like Cu and Ru. Characterization of the graphene has been done with Raman and contact angle measurement and recently quartz crystal microbalance (QCM) has been employed. The underpotential deposition (UPD) process of Bi on Ru metal surface is studied using electrochemical quartz crystal microbalance (EQCM) and XPS techniques. Both Bi UPD and Bi bulk deposition are clearly observed on Ru in 1mM Bi (NO3)3/0.5M H2SO4. Bi monolayer coverage calculated from mass (MLMass) and from charge (MLCharge) were compared with respect to the potential scanning rates, anions and ambient controls. EQCM results indicate that Bi UPD on Ru is mostly scan rate independent but exhibits interesting difference at the slower scan. Bi UPD monolayer coverage calculated from cathodic frequency change (ΔfCathodic) is significantly smaller than the monolayer coverage derived from integrated charge under the cathodic ...
