Suppressive effects of a stimulus correlated with reprimands for automatically-maintained eye poking.

Suppressive effects of a stimulus correlated with reprimands for automatically-maintained eye poking.

Access: Use of this item is restricted to the UNT Community.
Date: May 2003
Creator: McKenzie, Scott Daniel
Description: A functional analysis, conducted to assess the variables maintaining the chronic eye poking of a female diagnosed with profound mental retardation, indicated that the behavior persisted in the absence of social contingencies. A procedure was initiated in a training environment in which a punisher (mild reprimand) was delivered contingent on eye poking in the presence, but not in the absence, of a neutral stimulus (wristbands). Using a combination of multiple baseline and multielement experimental designs, it was determined that that eye poking was suppressed in the presence of the previously neutral stimulus, even in environments in which the reprimand contingency was inoperative.

The Symbolic Representation of Latinos: A Content Analysis of Prime-Time Television

The Symbolic Representation of Latinos: A Content Analysis of Prime-Time Television

Access: Use of this item is restricted to the UNT Community.
Date: August 2001
Creator: McKenzie-Elliott, Tracey M.
Description: The media are powerful agents of socialization in modern society influencing values, beliefs, and attitudes of the culture that produces them. Both the quantity and quality of Latino images in the media may reflect and reinforce the place of Latinos in United States society. This study examines how Latinos are portrayed in television entertainment programming by addressing two major research questions: 1) What is the extent of Latino recognition on prime-time television? and 2) What is the extent of respect accorded Latinos on prime-time television? A one-week sample of prime-time television programming airing on three networks yielded 47 programs and 807 characters for analysis. Using content analysis methodology, recognition is identified by examining the frequency and proportional representation of Latino television portrayals and respect is measured by examining the types and significance of these roles. The results indicate an overall lack of diversity on prime-time television with only 11 of the 47 programs analyzed reaching 50% or more of the maximum possible diversity in their racial and ethnic portrayals. Specifically, Latinos represent only 3% of primetime television characters, less than one-fourth of their proportion of the nation's population. Compared to non-Hispanic Whites, Blacks, and Asians, Latinos are the group least ...

Gene Expression Profiling of the nip Mutant in Medicago truncatula

Gene Expression Profiling of the nip Mutant in Medicago truncatula

Date: August 2007
Creator: McKethan, Brandon Lee
Description: The study of root nodule symbiosis between nitrogen-fixing bacteria and leguminous plant species is important because of the ability to supplement fixed nitrogen fertilizers and increase plant growth in poor soils. Our group has isolated a mutant called nip in the model legume Medicago truncatula that is defective in nodule symbiosis. The nip mutant (numerous infections with polyphenolics) becomes infected by Sinorhizobium meliloti but then accumulates polyphenolic defense compounds in the nodule and fails to progress to a stage where nitrogen fixation can occur. Analysis of the transcriptome of nip roots prior to inoculation with rhizobia was undertaken using Affymetric Medicago Genome Array microarrays. The total RNA of 5-day old uninoculated seedlings was analyzed in triplicate to screen for the NIP gene based on downregulated transcript levels in the mutant as compared to wild type. Further microarray data was generated from 10 days post inoculation (dpi) nip and wild type plants. Analysis of the most highly downregulated transcripts revealed that the NIP gene was not identifiable based on transcript level. Putative gene function was assigned to transcripts with altered expression patterns in order to characterize the nip mutation phenotypically as inferred from the transcriptome. Functional analysis revealed a large number ...

The Relationship of Subtle and Overt Psychological Abuse to Women's Self-Concept and Psychological Symptoms

The Relationship of Subtle and Overt Psychological Abuse to Women's Self-Concept and Psychological Symptoms

Date: August 1997
Creator: McKibbin, Christine L.
Description: Research has documented an association between sustained overt psychological abuse and women's self-concept and psychological distress. However, the focus on overt domination and control limits our understanding of its impact and is a weakness addressed in this study. Women in distressed relationships who had sustained severe psychological abuse from a partner and either no, moderate, or serious violence met inclusion criteria.

Professional Widow

Professional Widow

Date: May 2004
Creator: McKinley, Katherine L.
Description: The focus of my graduate work was to figure my way through a variety of challenges and transitions I was going through as a graduate student and simply as a person finding my way through my education to discover who I am and who I want to become. Perhaps my themes didn't focus primarily on these events in a literal sense, but I think the transitions in my artwork have become obvious through my time spent at UNT and the variations on a theme I have dealt with. All of my work deals with love, attraction, repulsion and the consequences we deal with as human beings when we make choices according to whom we choose to have relations with. It became very important for me to deal with these issues in an effort to discover what my expectations of myself as an artist and a person are.

The Luxury of Tears: A Secondary Survivor's Story

The Luxury of Tears: A Secondary Survivor's Story

Access: Use of this item is restricted to the UNT Community.
Date: December 1999
Creator: McKinney, Kelli
Description: As the written accompaniment for The Luxury of Tears, a twelve-minute documentary video exploring the emotional impact of sexual assault on male survivors and their partners, this document examines the visual texts of both the fiction and nonfiction genres. Specifically, I contend that fiction film manufactures male survivorship with regard to rape events in such manner which contributes to the thematization of social silence. Such silence perpetuates the feminization of rape as a social problem, and dissolves the development of male survivor resources. A discussion of production processes, challenges, and resolutions is included.
