Is Mind Wandering the Mechanism Responsible for Life Stress Induced Impairments in Working Memory Capacity?

Is Mind Wandering the Mechanism Responsible for Life Stress Induced Impairments in Working Memory Capacity?

Date: August 2011
Creator: Banks, Jonathan Britten
Description: The relationship between life stress and working memory capacity (WMC) has been documented in college students and older adults. It has been proposed that intrusive thoughts about life stress are the mechanism responsible for the impairments seen in WMC. To examine the mechanism responsible for these impairments the current study attempted to induce intrusive thoughts about personal events. The current study allowed for a test of predictions made by two theories of mind wandering regarding the impact of these intrusive thoughts on WMC task performance. One hundred fifty undergraduates were assigned to a control group, positive event group, or negative event group. Participants in the positive and negative event groups completed a short emotional disclosure about an imagined future positive or negative event, respectively, to induce positive or negative intrusive thoughts. WMC measures were completed prior to and following the emotional writing. Results indicated a significant relationship between WMC and mind wandering, however the writing manipulation did not result in any consistent changes in intrusive thoughts or WMC. The results suggest a causal relationship between WMC and mind wandering. The emotional valence of the intrusive thought altered the impact on WMC. No relationship was seen between the measures of stress ...

Is Mindfulness Just Another Ego Depletion Exercise?

Is Mindfulness Just Another Ego Depletion Exercise?

Date: May 2014
Creator: Connally, Melissa Londoño
Description: Given increasing interest in the therapeutic benefits of mindfulness, limitations of its treatment utility are frequently questioned. As such, the purpose of the study was to examine the effects of mindfulness on a subsequent self-control task in a sample of college students. A total of 67 participants were randomly assigned to one of three conditions: a control condition, an experimental mindfulness-only condition or a comparison expectancy-plus-mindfulness condition to investigate the utility of mindfulness practice when motivated by an outcome of increased self-control. Results did not indicate a difference in persistence on a difficult task between conditions, regardless of the manipulation. Conceptual and experimental limitations of current study’s findings, as well as future directions, are discussed.

"Is She Going to Die or Survive with Her Baby?": The Aftermath of Illegitimate Pregnancies in the Twentieth Century American Novels

"Is She Going to Die or Survive with Her Baby?": The Aftermath of Illegitimate Pregnancies in the Twentieth Century American Novels

Access: Use of this item is restricted to the UNT Community.
Date: August 2006
Creator: Liu, Li-Hsion
Description: This dissertation is mainly based on the reading of three American novels to explore how female characters deal with their illegitimate pregnancies and how their solutions re-shape their futures and affect their inner growth. Chapter 1 discusses Dorinda Oakley's premarital pregnancy in Ellen Glasgow's Barren Ground and draws the circle of limits from Barbara Welter's "four cardinal virtues" (purity, submissiveness, domesticity, and piety) which connect to the analogous female roles (daughter, sister, wife, and mother). Dorinda's childless survival reconstructs a typical household from her domination and absence of maternity. Chapter 2 examines Ántonia Shimerda's struggles and endurance in My Ántonia by Willa Cather before and after Ántonia gives birth to a premarital daughter. Ántonia devotes herself to being a caring mother and to looking after a big family although her marriage is also friendship-centered. Chapter 3 adopts a different approach to analyze Charlotte Rittenmeyer's extramarital pregnancy in The Wild Palms by William Faulkner. As opposed to Dorinda and Ántonia who re-enter domesticity to survive, Charlotte runs out on her family and dies of a botched abortion. To help explain the aftermath of illicit pregnancies, I extend or shorten John Duvall's formula of female role mutations: "virgin>sexually active (called whore)>wife" to ...

Is the Road to Hell Paved with Good Intentions? The Effect of U.S. Foreign Assistance and Economic Policy on Human Rights

Is the Road to Hell Paved with Good Intentions? The Effect of U.S. Foreign Assistance and Economic Policy on Human Rights

Date: August 2001
Creator: Callaway, Rhonda L.
Description: Theories in the international political economy literature, economic liberalism and dependency, are explored in order to test the effect of U.S. aid, trade, and investment on human rights conditions in recipient states. Two measures of human rights conditions serve as dependent variables: security rights and subsistence rights. The data cover approximately 140 countries from 1976-1996. Pooled cross-sectional time series analysis, utilizing ordinary least squares (OLS) with panel corrected standard errors, is employed due to the temporal and spatial characteristics of the data. The results indicate that foreign assistance and economic policy may not be the best approaches to altering poor human rights practices in the area of security rights. Economic and military aid is negatively associated with levels of security rights, supporting the traditional dependency perspective. While the results from trade and investment are generally in the positive direction, the lack of consistent statistical evidence suggests that increased trade and investment relationships do not dramatically improve security rights. We can conclude, however, that trade and investment fail to have the negative effect on security rights in less developed countries which critics of globalization suggest. Economic aid has a statistically significant negative effect on subsistence rights, while military aid seems to ...

Is There Justice in Mercy?  the Retributive Philosophies of Executive Clemency

Is There Justice in Mercy? the Retributive Philosophies of Executive Clemency

Date: May 2013
Creator: Gibbs, Gina N.
Description: Executive clemency is assumed to be a mechanism to correct miscarriages of justice brought about by the criminal justice system, yet little empirical research exists to confirm this assumption. This research study examined the types of rationales cited in 799 cases of executive clemency from six states from 2005 to 2012. Rationales based upon retributive philosophies, in which a miscarriage of justice was cited, were further analyzed. This analysis revealed that only seven percent of all clemency decisions from the examined states cited retributive rationales. Of the fifty-six grants of clemency that cited retributive rationales, most were granted in the forms of pardons. The analysis indicated that executive clemency is utilized as a mechanism to correct injustices, specifically in cases of innocence. This study concludes with a discussion of policy implications and the reliance on executive clemency as a fail-safe to the criminal justice system.

Is video modeling enough to teach parent-child interactions? Toward a systematic evaluation of the key components of video modeling.

Is video modeling enough to teach parent-child interactions? Toward a systematic evaluation of the key components of video modeling.

Date: May 2008
Creator: Whaley-Carr, Anna Marie
Description: Parent-child interactions help set the foundation for a child's development. It is therefore important to investigate the relative efficiency and efficacy of procedures used to train them. One procedure that researchers continue to explore is video modeling. The current study evaluated the effect of a video model that displayed favorable parent-child interactions and a modified model with embedded instructions to determine if the introduction of either of these models would alter parent-child interactions. Both models were presented alone without supplemental guidance. Three families were involved in the study. The results showed no systematic change across families or conditions as a result of video viewing and are discussed within context of the needs of the parent, adequate stimulus control, community to support behavior change, measurement sensitivity, and influence of methodology. This study provided a great baseline for future studies to explore the necessary components to create an effective video model.

Isolation and analysis of cotton genomic clones encompassing a fatty acid desaturase (FAD2) gene

Isolation and analysis of cotton genomic clones encompassing a fatty acid desaturase (FAD2) gene

Date: May 2001
Creator: Kongcharoensuntorn, Wisatre
Description: Polyunsaturated fatty acids are major structural components of plant chloroplast and endoplasmic reticulum membranes. Two fatty acid desaturases (designated FAD2 and FAD3) desaturate 75% of the fatty acids in the endoplasmic reticulum. The w -6 fatty acid desaturase (FAD2) may be responsible for cold acclimation response, since polyunsaturated phospholipids are important in helping maintain plant viability at lowered temperatures. To study regulation of FAD2 gene expression in cotton, a FAD2 gene was isolated from two genomic libraries using an Arabidopsis FAD2 hybridization probe and a cotton FAD2 5¢ -flanking region gene-specific probe, respectively. A cotton FAD2 gene was found to be in two overlapping genomic clones by physical mapping and DNA sequencing. The cloned DNA fragments are identical in size to cotton FAD2 genomic DNA fragments shown by genomic blot hybridization. The cotton FAD2 coding region has 1,155 bp with no introns and would encode a putative polypeptide of 384 amino acids. The cotton FAD2 enzyme has a high identity of 75% with other plant FAD2 enzymes. The enzyme has three histidine-rich motifs that are conserved in all plant membrane desaturases. These histidine boxes may be the iron-binding domains for reduction of oxygen during desaturation. To confirm that this FAD2 ...
