Next Generation Extractants for Cesium Separation from High-Level Waste: From Fundamental Concepts to Site Implementation

This project seeks a fundamental understanding and major improvement in cesium separation from high-level waste by cesium-selective calixcrown extractants. Systems of particular interest involve novel solvent-extraction systems containing specific members of the calix[4]arene-crown-6 family, alcohol solvating agents, and alkylamines. Questions being addressed bear upon cesium binding strength, extraction selectivity, cesium stripping, and extractant solubility. Enhanced properties in this regard will specifically benefit applied projects funded by the USDOE Office of Environmental Management to clean up sites such as the Savannah River Site (SRS), Hanford, and the Idaho National Environmental and Engineering Laboratory. The most direct beneficiary will be the SRS Salt Processing Project, which has recently identified the Caustic-Side Solvent Extraction (CSSX) process employing a calixcrown as its preferred technology for cesium removal from SRS high-level tank waste.

From Lost Cause to Female Empowerment: The Texas Division of the United Daughters of the Confederacy, 1896-1966 (open access)

From Lost Cause to Female Empowerment: The Texas Division of the United Daughters of the Confederacy, 1896-1966

The Texas Division of the United Daughters of the Confederacy (UDC) organized in 1896 primarily to care for aging veterans and their families. In addition to this original goal, members attempted to reform Texas society by replacing the practices and values of their male peers with morals and behavior that UDC members considered characteristic of the antebellum South, such as self-sacrifice and obedience. Over time, the organization also came to function as a transition vehicle in enlarging and empowering white Texas women's lives. As time passed and more veterans died, the organization turned to constructing monuments to recognize and promote the values they associated with the Old South. In addition to celebrating the veteran, the Daughters created a constant source of charity for wives and widows through a Confederate Woman's Home. As the years went by, the organization turned to educating white children in the “truth of southern history,” a duty they eagerly embraced. The Texas UDC proved effective in meeting its primary goal, caring for aging veterans and their wives. The members' secondary goal, being cultural shapers, ultimately proved elusivenot because the Daughters failed to stress the morals they associated with the Old South but because Texans never embraced …

Identifying AD/HD subtypes using the cognitive assessment system and the NEPSY (open access)

Identifying AD/HD subtypes using the cognitive assessment system and the NEPSY

The purpose of this study was to examine the ability of the Cognitive Assessment System (CAS) and the NEPSY, A Developmental Neuropsychological Assessment, to differentiate between the subtypes of Attention Deficit/ Hyperactivity Disorder (AD/HD). The CAS and NEPSY are neuropsychological instruments which provide norms for AD/HD children in general. This study examined the performance of the two subtypes of AD/HD on the CAS and NEPSY. In addition, this study examined the performance of the two AD/HD groups on the Screening Test for Auditory Processing Disorders (SCAN). Since AD/HD children tend to have difficulty with language, the SCAN was used to determine if any of the AD/HD subjects had auditory processing difficulties that might impact their performance on the CAS and/or NEPSY subtests. The sample consisted of 118 children between the ages of 8 and 12 years of age. Using the DSM-IV criteria, the children were diagnosed as having three types of AD/HD: A Predominantly Hyperactive-Impulsive Type (AD/HD-HI), a Predominantly Inattentive Type (AD/HD-I) and a Combined Type The subtypes were also identified by the Attention Deficit Disorders Evaluation Scale-Home Version (ADDES-H). Only two subtypes, AD/HD-I and AD/HD-C, were identified by the ADDES-H. There were not enough AD/HD-HI subjects to include in …

Responses of Federal Agencies and Airports We Surveyed About Access Security Improvements

Correspondence issued by the General Accounting Office with an abstract that begins "Earlier this year, in response to concerns about the use of stolen or counterfeit law enforcement badges or credentials to gain access to secure government buildings and airports, GAO conducted an undercover operation during which GAO special agents gained entry into many federal sites and two commercial airports in the Washington, D.C., area and in Orlando, Florida. GAO surveyed these federal facilities and airports, along with 23 other major federal agencies, about any security improvements that they may have taken as a result of GAO's investigation. All 43 agencies and airports queried responded to GAO's survey, and many said that they had either started or completed a security assessment of existing security policies and procedures. GAO has not verified whether the reported specific security enhancements have actually been implemented."

Streamlined Approach for Environmental Restoration (SAFER) Plan for Corrective Action Unit 356: Mud Pits and Disposal Sites, Nevada Test Site, Nevada (Revision No. 0, August 2001)

This Streamlined Approach for Environmental Restoration (SAFER) Plan addresses the actions necessary for the characterization and closure of Corrective Action Unit (CAU) 356, Mud Pits and Disposal Sites, as identified in the Federal Facility Agreement and Consent Order (FFACO). The CAU, located on the Nevada Test Site in Nevada, consists of seven Corrective Action Sites (CASs): CAS 03-04-01, Area 3 Change House Septic System; CAS 03-09-01, Mud Pit Spill Over; CAS 03-09-03, Mud Pit; CAS 03-09-04, Mud Pit; CAS 03-09-05, Mud Pit; CAS 20-16-01, Landfill; CAS 20-22-21, Drums. Sufficient information and process knowledge from historical documentation and investigations are the basis for the development of the phased approach chosen to address the data collection activities prior to implementing the preferred closure alternative for each CAS. The Phase I investigation will determine through collection of environmental samples from targeted populations (i.e., mud/soil cuttings above textural discontinuity) if contaminants of potential concern (COPCs) are present in concentrations exceeding preliminary action levels (PALs) at each of the CASs. If COPCs are present above PALs, a Phase II investigation will be implemented to determine the extent of contamination to support the appropriate corrective action alternative to complete closure of the site.

Coping Styles, Quality of Life, and Sexual Trauma in Women Veterans (open access)

Coping Styles, Quality of Life, and Sexual Trauma in Women Veterans

The purpose of the following study was to evaluate sexual trauma and the effects on women veteran's quality of life ratings and current and past coping strategies. Participants were screened for sexual trauma history and divided into five mutually exclusive categories: 1)childhood sexual trauma, 2)civilian adult sexual trauma, 3)military sexual trauma, 4)multiple sexual trauma, and 5)no sexual trauma. Results of the study were mixed, retaining some hypotheses and rejecting others. Results regarding differences in QOL for the sexual trauma groups were rejected, as none of the QOL analyses were significant. Issues of small effect size for the QOL measure and low power to detect differences are discussed as limitations in the current study. Several significant findings were detected in the coping analyses. As predicted, the no trauma group was found to use significantly more approach coping strategies than the sexual trauma group for the past problem. Additionally, the sexual trauma group used significantly more avoidant coping techniques for past problem than the no trauma group. No between group differences were detected for sexual trauma type, however, several significant differences emerged in the comparisons of the multiple sexual trauma and military sexual trauma group's past coping compared to the no sexual …

The Relationship between Executive and Psychosocial Functioning in Children Treated for a Brain Tumor

Access: Use of this item is restricted to the UNT Community
This study examined the relationship between executive and psychosocial functioning in 45 children and adolescents age 6 to 17 years who had been treated for a brain tumor. Executive functioning deficits can profoundly impact an adult's ability to function successfully in life. The purpose of the study was to evaluate the potential impact of executive functioning deficits on the day-to-day functioning in a pediatric population. The domains of executive functioning assessed included cognitive flexibility, conceptual thinking, sustained attention, and response inhibition. Psychosocial functioning was assessed using both parent and child report. Several significant relationships were found for adolescents ages 15 and older, with effect sizes ranging from medium to large. In particular, cognitive flexibility and conceptual thinking were significantly related to parent report of depression and adaptive functioning. Fewer significant relationships with smaller effect sizes were found for younger children. The results may reflect the developmental emergence of executive functioning abilities and late effects of executive functioning deficits upon psychosocial functioning. The correlational design of this study precludes definitive statements regarding the temporal nature of the relationship. Additional research, including longitudinal research and replicatory studies, will be needed to further investigate the developmental consequences of executive functioning impairment.

Patterns of Change in Semantic Clustering in Schizophrenia Spectrum Disorders: What Can it Tell Us about the Nature of Clustering Deficits (open access)

Patterns of Change in Semantic Clustering in Schizophrenia Spectrum Disorders: What Can it Tell Us about the Nature of Clustering Deficits

Semantic clustering has been used as a measure of learning strategies in a number of clinical populations and has been found to be deficient in individuals with Schizophrenia, but less attention has been paid to the dynamic use of this strategy over the course of fixed-order learning trials. In the current study, we examined this pattern of clustering use over trials in a sample of individuals with Schizophrenia, and explored whether the addition of this dynamic information would help us to better predict specific executive deficits. Results suggested that a decrease in semantic clustering across trials was associated with some executive deficits in the predicted manner. Nonetheless, the overall semantic clustering index generally proved more effective for the purposes, suggesting that in this population, the addition of dynamic information in strategy use is not likely to add considerably to clinical prediction and understanding.

A preliminary study of the effects of selective-serotonin re-uptake inhibitors (SSRIs) on central auditory processing

Access: Use of this item is restricted to the UNT Community
his study compared auditory behavioral and physiological measures among three subject groups: 1) Normal control subjects, 2) subjects who were on a prescribed SSRI for depression, and 3) subjects who were prescribed an SSRI for depression, but were not medicated at the time of testing. Test measures included: Standard audiological tests (audiometry and tympanometry), electrophysiological procedures for analysis of auditory- evoked brainstem and late responses, and standardized behavioral speech tests (SCAN-A, SSI, and the low predictability sentence list of the R-SPIN). Analysis of results indicated a statistically significant increase of group mean amplitude of the ABR peak V, from 15dBnSL to 55dBnSL, in the non-medicated group compared to controls. Also, the non-medicated group scored significantly less favorably than controls on the most challenging listening condition (-20 MCR) of the SSI, in the left ear. Although other test measures indicated consistent differences between these two groups, they were not, however, significant.

An Analysis of Major American Riots: Issues in Riots and Riot Control

Access: Use of this item is restricted to the UNT Community
By conducting sound research to understand the concepts surrounding rioting and efficient riot response tactics, professionals, especially whose main job is to ensure the tranquility in the society, will be better prepared to deal with all kinds of civil movements. The purpose of this study, consequently, is to meet the growing need for educational materials in this area and to provide riot response case studies, which demonstrate the numerous administrative challenges faced by law enforcement decision makers. In this study, seven major riots from throughout the United States are discussed including the Hay Market Riot of 1886, the Watts Riot of 1965, and Los Angeles Riots of 1992. Each riot case is studied in five different and independent stages: the setting and pre-disturbance situation, basic causes of the event, the disturbance situation, the response to the riot, and the aftermath of the incident. The study of all of these stages is intended to help police administrators acquire a general perspective on collective violence, and help them prevent future occurrences in their jurisdictions. In this thesis a special reference is given to the deficiencies of American riot policing and some recommendations were formed accordingly. Therefore, the study concludes with a list …

Masculine Gender Role Conflict and Psychological Well- Being: A Comparative Study of Heterosexual and Gay Men (open access)

Masculine Gender Role Conflict and Psychological Well- Being: A Comparative Study of Heterosexual and Gay Men

Masculine gender role conflict (MGRC) occurs when externally-imposed male gender role expectations have a negative impact on and consequences for men. The purpose of this study was to examine how men in a homogeneous setting (i.e., a college campus) compare on MGRC and psychological well-being, based on their self-identified sexual orientation. Utilizing canonical correlation analysis, 96 heterosexual men and 102 gay men were compared on four factors of MGRC (conflict between work and family, restrictive emotionality, restrictive affectionate behavior between men, and success, power, and competition) and five factors of psychological well-being (anger, anxiety, depression, self-esteem, and attitudes toward seeking psychological help). Findings for the heterosexual men were highly consistent with previous studies on MGRC and psychological well-being in a college-age population. Findings for the gay men indicated they had more problems with MGRC and psychological well-being than college-age and older gay men surveyed in the one published study on gay men and MGRC. Gay men who were single also reported more problems with restrictive emotionality, anger, anxiety, and depression, and had lower self-esteem, than gay men who were in a relationship. Between group differences were few, with gay men reporting significantly less restrictive affectionate behavior between men than heterosexual …
