An actor-partner interdependence model of attachment processes, conflict resolution, and psychological abuse on relationship quality in a community sample of heterosexual couples.

An actor-partner interdependence model of attachment processes, conflict resolution, and psychological abuse on relationship quality in a community sample of heterosexual couples.

Date: May 2009
Creator: Bretz, Karen
Description: The purpose of this study is to determine whether adult attachment style, psychological abuse in the marriage, conflict resolution strategies, and gender are associated with relational quality in childless couples in the early years of their marriage. Data were collected from 92 married couples who were recruited from university campuses, churches, and community organizations through e-mails, flyers, newspaper advertisements and mailings. Conceptualizing the interdependence of dyadic data from the actor-partner interdependence model (APIM), multilevel linear modeling (MLM) was used to analyze differences within and between couples. It was hypothesized that higher levels of attachment anxiety or avoidance, psychological abuse, and maladaptive conflict resolution strategies would be associated with lower relational quality. Results indicated that attachment avoidance had stronger associations with relational quality than did attachment anxiety, and that higher levels of attachment avoidance were associated with lower relational quality. Additionally, findings indicated a direct negative relationship between both actor and partner psychological abuse and the actor's relational quality. The discussion section addresses strengths and limitations of the present study as well as directions for future research.

N-Acylethanolamine metabolism during seed germination: Molecular identification of a functional N-acylethanolamine amidohydrolase.

N-Acylethanolamine metabolism during seed germination: Molecular identification of a functional N-acylethanolamine amidohydrolase.

Date: August 2004
Creator: Shrestha, Rhidaya
Description: N-Acylethanolamines (NAEs) are endogenous lipid metabolites that occur in a variety of dry seeds, and their levels decline rapidly during the first few hours of imbibition (Chapman et al., 1999, Plant Physiol., 120:1157-1164). Biochemical studies supported the existence of an NAE amidohydrolase activity in seeds and seedlings, and efforts were directed toward identification of DNA sequences encoding this enzyme. Mammalian tissues metabolize NAEs via an amidase enzyme designated fatty acid amide hydrolase (FAAH). Based on the characteristic amidase signature sequence in mammalian FAAH, a candidate Arabidopsis cDNA was identified and isolated by reverse transcriptase-PCR. The Arabidopsis cDNA was expressed in E. coli and the recombinant protein indeed hydrolyzed a range of NAEs to free fatty acids and ethanolamine. Kinetic parameters for the recombinant protein were consistent with those properties of the rat FAAH, supporting identification of this Arabidopsis cDNA as a FAAH homologue. Two T-DNA insertional mutant lines with disruptions in the Arabidopsis NAE amidohydrolase gene (At5g64440) were identified. The homozygous mutant seedlings were more sensitive than the wild type to exogenously applied NAE 12:0. Transgenic seedlings overexpressing the NAE amidohydrolase enzyme showed noticeably greater tolerance to NAE 12:0 than wild type seedlings. These results together provide evidence in vitro ...

Adapting Filial Therapy for Families who have a Child with a Life-Threatening Illness

Adapting Filial Therapy for Families who have a Child with a Life-Threatening Illness

Date: August 2004
Creator: Steen, Rheta LeAnne
Description: Utilizing a collective case study design, I examined and described the filial therapy (FT) process and adaptations discovered to be necessary and unnecessary in working with families who have a child with a life-threatening illness in the hospital setting. Data from a total of 7 parents was utilized, including those who terminated early, in order to gain a greater understanding of adapting FT for families who have a child with a life-threatening illness and their participation patterns. The parents attended 10 one- to two-hour FT sessions. The data was analyzed to examine for themes, patterns and relationships intrinsically with each case participant, as well as across cases. Analysis indicated that parents with a child with a life-threatening illness had great difficulty committing to attend FT; and a high rate of attrition occurred for those who did commit. A theme regarding flexibility was found to be of eminent importance in a variety of manifestations including therapeutic methods, session format, location and time of sessions, and intense vs traditional FT. Therapeutic adaptations in flexibility found to be important including openness to cathartic and personal parenting sessions, tolerance of forgetfulness, and lowering typical therapeutic concerns of dependency in the relationship. An inability for ...

Adaptive planning and prediction in agent-supported distributed collaboration.

Adaptive planning and prediction in agent-supported distributed collaboration.

Date: December 2004
Creator: Hartness, Ken T. N.
Description: Agents that act as user assistants will become invaluable as the number of information sources continue to proliferate. Such agents can support the work of users by learning to automate time-consuming tasks and filter information to manageable levels. Although considerable advances have been made in this area, it remains a fertile area for further development. One application of agents under careful scrutiny is the automated negotiation of conflicts between different user's needs and desires. Many techniques require explicit user models in order to function. This dissertation explores a technique for dynamically constructing user models and the impact of using them to anticipate the need for negotiation. Negotiation is reduced by including an advising aspect to the agent that can use this anticipation of conflict to adjust user behavior.

Addition, Omission and Revision: the Stylistic Changes Made to Zehn Variationen über ein Präludium von Chopin by Ferruccio Busoni, with Three Recitals of Selected Works by J.S. Bach, D. Scarlatti, Beethoven, Brahms, Debussy, Schumann and Liszt

Date: December 1994
Creator: Yoon, Soomee
Description: This study examines what Busoni meant by "formal deficiencies" when he described his 1884 version of Chopin Variations, and reveals that changes made to the 1884 version during its process of revision in 1922 correct the "formal deficiencies" and show a fundamental change in Busoni's compositional style and perception of musical motion. Including a detailed analysis of the modifications, omissions, and additions made to the 1922 version (including an examination of the Chopin Prelude in C minor, op. 28, No. 20 as a theme to reveal aspects of its construction used in the variation process), which shows how these changes affect the work's compositional structure.

Adherence/Diffusion Barrier Layers for Copper Metallization: Amorphous Carbon:Silicon Polymerized Films

Adherence/Diffusion Barrier Layers for Copper Metallization: Amorphous Carbon:Silicon Polymerized Films

Date: May 2004
Creator: Pritchett, Merry
Description: Semiconductor circuitry feature miniaturization continues in response to Moore 's Law pushing the limits of aluminum and forcing the transition to Cu due to its lower resistivity and electromigration. Copper diffuses into silicon dioxide under thermal and electrical stresses, requiring the use of barriers to inhibit diffusion, adding to the insulator thickness and delay time, or replacement of SiO2 with new insulator materials that can inhibit diffusion while enabling Cu wetting. This study proposes modified amorphous silicon carbon hydrogen (a-Si:C:H) films as possible diffusion barriers and replacements for SiO2 between metal levels, interlevel dielectric (ILD), or between metal lines (IMD), based upon the diffusion inhibition of previous a-Si:C:H species expected lower dielectric constants, acceptable thermal conductivity. Vinyltrimethylsilane (VTMS) precursor was condensed on a titanium substrate at 90 K and bombarded with electron beams to induce crosslinking and form polymerized a-Si:C:H films. Modifications of the films with hydroxyl and nitrogen was accomplished by dosing the condensed VTMS with water or ammonia before electron bombardment producing a-Si:C:H/OH and a-Si:C:H/N and a-Si:C:H/OH/N polymerized films in expectation of developing films that would inhibit copper diffusion and promote Cu adherence, wetting, on the film surface. X-ray Photoelectron Spectroscopy was used to characterize Cu metallization of ...

Adhesion/diffusion barrier layers for copper integration: carbon-silicon polymer films and tantalum substrates

Adhesion/diffusion barrier layers for copper integration: carbon-silicon polymer films and tantalum substrates

Date: December 1999
Creator: Chen, Li
Description: The Semiconductor Industry Association (SIA) has identified the integration of copper (Cu) with low-dielectric-constant (low-k) materials as a critical goal for future interconnect architectures. A fundamental understanding of the chemical interaction of Cu with various substrates, including diffusion barriers and adhesion promoters, is essential to achieve this goal. The objective of this research is to develop novel organic polymers as Cu/low-k interfacial layers and to investigate popular barrier candidates, such as clean and modified tantalum (Ta) substrates. Carbon-silicon (C-Si) polymeric films have been formed by electron beam bombardment or ultraviolet (UV) radiation of molecularly adsorbed vinyl silane precursors on metal substrates under ultra-high vacuum (UHV) conditions. Temperature programmed desorption (TPD) studies show that polymerization is via the vinyl groups, while Auger electron spectroscopy (AES) results show that the polymerized films have compositions similar to the precursors. Films derived from vinyltrimethyl silane (VTMS) are adherent and stable on Ta substrates until 1100 K. Diffusion of deposited Cu overlayers is not observed below 800 K, with dewetting occurred only above 400 K. Hexafluorobenzene moieties can also be incorporated into the growing film with good thermal stability. Studies on the Ta substrates demonstrate that even sub-monolayer coverages of oxygen or carbide on polycrystalline ...

Adlerian Life Style and the Myers-Briggs Type Indicator

Adlerian Life Style and the Myers-Briggs Type Indicator

Date: May 1993
Creator: Doss, Carol Rose
Description: The possibility of a relationship between Adlerian life style, as measured by the Life Style Personality Inventory (LSPI), and the Myers-Briggs Type Indicator (MBTI) was examined by this research. The goal of this study was to clarify the relationship between these instruments to broaden the applicability of both instruments for both research and clinical endeavors. Life style is a concept which is vital to therapeutic intervention from an Adlerian frame of reference. Assessment of life style typically involves lengthy therapist interviews. Both the LSPI and the MBTI are questionnaires designed to measure personality variables. The 117 subjects for this study were solicited from individuals seeking counseling from an urban community counseling center. The individuals served by this agency are primarily those diagnosed with Adjustment Disorders. The LSPI and the MBTI were administered individually to each subject. Means and standard deviations were computed for the seven LSPI themes and the MBTI total. Due to a lack of research support for Theme 4 by the LSPI author, the data for this theme were disregarded. The same research indicated a strong bipolar relationship for Themes 7 and 8 (Displaying Inadequacy and Social Interest), which prompted the inclusion of Theme 8 in subsequent data ...
