Contextualizing the Law: Sentencing Decisions of Sexual Assault Cases of Dallas County, 1999-2005 (open access)

Contextualizing the Law: Sentencing Decisions of Sexual Assault Cases of Dallas County, 1999-2005

The incidence of sexual assault inundates the courts with many cases each year. Given the unique nature of the crime, judges and juries are faced with an array of different scenarios to which they are required to make fair, justifiable and consistent decisions. I examine child sexual assault cases of Dallas County 1999-2005, I look at both legal and extralegal factors including case characteristics, institutional characteristics and characteristics of the defendants and the victims. First, I examine the impact of the independent variables on sentence length using regression analysis to determine influences on sentencing for judges and juries. Second, I examine the same factors using Probit analysis to determine which characteristics make a life sentence more probable for those decision-makers.

Correspondence Between Verbal Behavior About Reinforcers and Performance Under Schedules of Reinforcement. (open access)

Correspondence Between Verbal Behavior About Reinforcers and Performance Under Schedules of Reinforcement.

Important advancements have been made in the identification of reinforcers over the past decade. The use of preference assessments has become a systematic way to identify preferred events that may function as reinforcers for an individual's behavior. Typically, preference assessments require participants to select stimuli through verbal surveys or engagement with stimuli as preferred or non-preferred. Not all studies go on to directly test the effects of the preferred stimuli, and even fewer studies directly test for the effects of the non- preferred stimuli. The present study systematically identified preferred and non-preferred stimuli in adult human subjects by verbal report and then proceeded to test the effects of both verbally reported preferred and non preferred events on single and concurrent schedules of reinforcement. The results are discussed in terms of contemporary concerns regarding preference and reinforcer assessments.

Creole Angel: The Self-Identity of the Free People of Color of Antebellum New Orleans (open access)

Creole Angel: The Self-Identity of the Free People of Color of Antebellum New Orleans

This thesis is about the self-identity of antebellum New Orleans's free people of color. The emphasis of this work is that French culture, mixed Gallic and African ancestry, and freedom from slavery served as the three keys to the identity of this class of people. Taken together, these three factors separated the free people of color from the other major groups residing in New Orleans - Anglo-Americans, white Creoles and black slaves. The introduction provides an overview of the topic and states the need for this study. Chapter 1 provides a look at New Orleans from the perspective of the free people of color. Chapter 2 investigates the slaveownership of these people. Chapter 3 examines the published literature of the free people of color. The conclusion summarizes the significance found in the preceding three chapters and puts their findings into a broader interpretive framework.

Dead Men Talking: Content Analysis of Prisoners' Last Words, Innocence Claims and News Coverage from Texas' Death Row (open access)

Dead Men Talking: Content Analysis of Prisoners' Last Words, Innocence Claims and News Coverage from Texas' Death Row

Condemned prisoners in Texas and most other states are given an opportunity to make a final statement in the last moments before death. An anecdotal review by the author of this study over the last 15 years indicates that condemned prisoners use the opportunity for a variety of purposes. They ask forgiveness, explain themselves, lash out at accusers, rail at the system, read poems, say goodbyes to friends and family, praise God, curse fate - and assert their innocence with their last breaths. The final words also are typically heard by a select group of witnesses, which may include a prisoner's family and friends, victim's relatives, and one or more journalists. What the public knows about a particular condemned person's statement largely depends on what the journalists who witness the executions chose to include in their accounts of executions, the accuracy of their notes, and the completeness of the statements that are recorded on departments of correction websites or records. This paper will examine, through rhetorical and content analyses, the final words of the 355 prisoners who were executed in Texas between 1976 and 2005, identify those who made unequivocal claims of innocence in their final statements, and analyze news …

Depression, Activities of Daily Living, and Retirement

Access: Use of this item is restricted to the UNT Community
Depression is a common clinical and subclinical psychiatric disorder in the middle-age to older adult population. This study examined the relationship between depression and activities of daily living (ADLs) in middle-age to older adults. This study examined longitudinal data from the 1998, wave 4, and 2000, wave 5, of the Health and Retirement Study (HRS), a National Panel Study sponsored by the National Institute on Aging. A negative cross-sectional and longitudinal relationship between higher ADL scores and depression was hypothesized. A goal of the present study was to determine the temporal precedence of these two constructs using a cross-lag panel design to first examine the cross-sectional relationship between ADLs and depression at time-one and at time-two, and then the time-one to time-two longitudinal relationships to examine temporal precedence possible causal relationships. Finally, differences in these correlational relationships by retirement status and then by marital status were tested. There were several interesting findings, including those who were retired in both 1998 and 2000 reported fewer ADLs (i.e., worse functioning), but also reported better health than those who were working in both 1998 and 2000. Similarly, those people who were not married in both 1998 and 2000 reported fewer ADLs but better …

Developing Capacity: The IMF's Impact on State Capacity (open access)

Developing Capacity: The IMF's Impact on State Capacity

The purpose of this thesis is to examine the impact of International Monetary Fund (IMF) loans since the adoption of the governance mandate on overall government capability. The study will explore whether the presence of IMF loans in developing countries enhances state capacity. Administrative capacity is of particular importance because it is a requisite for the integration of state and society in the national political arena and encourages joint involvement of government and citizenry in overall representation of societal interests. The model designed to test the two primary hypotheses is comprised of a simultaneous system of equations. Despite criticisms of IMF conditionality arrangements, it appears that these programs are largely effective at increasing administrative capacity, an important factor in achieving economic growth and national ownership of IMF development programs.

Differential Scoring Patterns on the Clock Drawing Test: a Comparison of Vascular Dementia and Alzheimer's Dementia. (open access)

Differential Scoring Patterns on the Clock Drawing Test: a Comparison of Vascular Dementia and Alzheimer's Dementia.

This study examined differences in scoring patterns among those diagnosed with Alzheimer's dementia and vascular dementia on the clock-drawing test. Archival clock drawing data was retrieved on 279 patients presenting at a county hospital-based memory clinic. Analysis of drawings was based on frequency of qualitative errors, as well as an overall quantitative score. Mean comparisons found those patients with Alzheimer's dementia to perform worse on both quantitative and qualitative scoring measures. However, Pearson's chi-squared test revealed a significantly higher rate of spacing errors among subjects with vascular dementia. Such lends support to my hypothesis that impaired executive functioning in vascular dementia patients would lead to poor qualitative performance. Logistic regression found significant predictive ability for the qualitative criteria in diagnosis (χ2 = 25.49, p < .001), particularly the rate of omission (z = 8.96, p = .003) and addition errors (z = 7.58, p = .006). Such findings hold important implications for the use of qualitative criteria in cognitive screening assessments.

Diphosphine Ligand Substitution in H4Ru4(CO)12: X-ray Diffraction Structures and Reactivity Studies of the Diphosphine Substituted Cluster Products

Access: Use of this item is restricted to the UNT Community
The tetraruthenium cluster H4Ru4(CO)12 has been studied for its reactivity with the unsaturated diphosphine ligands (Z)-Ph2PCH=CHPPh2, 4,5-bis (diphenylphosphino)-4-cyclopenten-1,3-dione, bis(diphenyphosphino)benzene and 1,8- bis(diphenyl phosphino)naphthalene under thermal, near-UV photolysis, and Me3NO-assisted activation. All three cluster activation methods promote loss of CO and furnish the anticipated substitution products that possess a chelating diphosphine ligand. Clusters 1, 2, 3 and 4 have been characterized in solution by IR and NMR spectroscopies, and these data are discussed with respect to the crystallographically determined structures for all new cluster compounds. The 31P NMR spectral data and the solid-state structures confirm the presence of a chelating diphosphine ligand in all four new clusters. Sealed NMR tubes containing clusters 1, 2, 3 and 4 were found to be exceeding stable towards near-UV light and temperatures up to ca. 100°C. The surprisingly robust behavior of the new clusters is contrasted with the related cluster Ru3(CO)10(bpcd) that undergoes fragmentation to the donor-acceptor compound Ru2(CO)6(bpcd) and the phosphido-bridged compound Ru2(CO)6 (µ-PPh2)[µ-C=C(PPh2)C(O)CH2C(O)] under mild conditions. The electrochemical properties have been investigated in the case of clusters 1 and 2 by cyclic voltammetry, and the findings are discussed with respect to the reported electrochemical data on the parent cluster H4Ru4(CO)12.

Do As They Say, and As They Do: An Integrated Approach to the Study of Norm Influence on Truth Commission Initiation, 1976-2003 (open access)

Do As They Say, and As They Do: An Integrated Approach to the Study of Norm Influence on Truth Commission Initiation, 1976-2003

Truth commissions are bodies established in political transition, and they have the stated purpose of reckoning with human rights abuses committed by members of former regimes. The question driving this research is "Why have truth commissions increased so rapidly in the last 20 years?" This study moves beyond current research, which suggests that particular domestic political circumstances alone determine choice of transitional justice mechanisms. I argue that an international rule of behavior, the transitional restorative norm, has emerged and spread to decision-makers in countries of transition. In support of this notion, I perform a pre-theoretical historical analysis of transitional justice and develop a theory of decision-making in transition-which is later tested with quantitative statistics. This integrated approach allows for increased scientific rigor in the examination of international norms. Ultimately, the study demonstrates an interrelationship between shared ideas and political environments in the determination of domestic policy.

Documentary Film: Access Denied

Access: Use of this item is restricted to the UNT Community
Sculptor Eric McGehearty incorporates dyslexia, a learning disability, into his artwork to express his challenges with his limited ability to recognize and understand the written word. The film Access Denied focuses on Eric and his disability. Recognized in 1896, dyslexia has been studied and researched by scientists and educators. New assistive technology is now available to aid dyslexics in reading and writing. Specialized schools provide techniques to improve student learning. However, some options are not readily available to the general public; therefore, information about how to deal with the disability is not easily accessed. The aims of this documentary are to raise awareness of available resources to assist with learning as well as to demonstrate a relationship between art and dyslexia.

Documentary Film: Love's Story

Access: Use of this item is restricted to the UNT Community
Abstract Love's Story is a documentary journey into the storytelling world, where the themes of love and memory connect the audience to a unique set of film interviewees. Marie and Alexis provide interesting recollections about their individual pasts, while Cherie guides the course of the film with her expert theories about the nature of storytelling. What initially appears a simple film, actually provides a multi-tiered commentary tackling issues of memory, love, and perseverance. The film equally highlights the nature of storytelling to encourage audiences to critically dissect the stories around them in the world. Presented visually through minimalist animation and aurally through a mix of interviews, sound effects, and music, Love's Story is a poetic film about the process of storytelling and the interconnectedness of the memories individuals tell.

A Dual Dielectric Approach for Performance Aware Reduction of Gate Leakage in Combinational Circuits (open access)

A Dual Dielectric Approach for Performance Aware Reduction of Gate Leakage in Combinational Circuits

Design of systems in the low-end nanometer domain has introduced new dimensions in power consumption and dissipation in CMOS devices. With continued and aggressive scaling, using low thickness SiO2 for the transistor gates, gate leakage due to gate oxide direct tunneling current has emerged as the major component of leakage in the CMOS circuits. Therefore, providing a solution to the issue of gate oxide leakage has become one of the key concerns in achieving low power and high performance CMOS VLSI circuits. In this thesis, a new approach is proposed involving dual dielectric of dual thicknesses (DKDT) for the reducing both ON and OFF state gate leakage. It is claimed that the simultaneous utilization of SiON and SiO2 each with multiple thicknesses is a better approach for gate leakage reduction than the conventional usage of a single gate dielectric (SiO2), possibly with multiple thicknesses. An algorithm is developed for DKDT assignment that minimizes the overall leakage for a circuit without compromising with the performance. Extensive experiments were carried out on ISCAS'85 benchmarks using 45nm technology which showed that the proposed approach can reduce the leakage, as much as 98% (in an average 89.5%), without degrading the performance.

Educational Opportunities Available for Women in Antebellum Texas (open access)

Educational Opportunities Available for Women in Antebellum Texas

The matter of formal education for women in the antebellum South raises many questions, especially for the frontier state of Texas. Were there schools for young women in antebellum Texas? If so, did these schools emphasize academic or ornamental subjects? Did only women from wealthy families attend? This study answered these questions by examining educational opportunities in five antebellum Texas counties. Utilizing newspapers, probate records, tax records, and the federal census, it identified schools for girls in all of the counties and found that those schools offered academic as well as ornamental subjects. Almost all of the girls who attended those schools came from privileged families. Schools were available for young women in antebellum Texas, but generally only those from wealthy families were able to attend.

The Effect of Parental Divorce on Romantic Beliefs and Relationship Characteristics (open access)

The Effect of Parental Divorce on Romantic Beliefs and Relationship Characteristics

This study investigated a proposed model hypothesizing that parental divorce would directly effect romantic beliefs and attitudes, romantic attachment and relationship characteristics. A sample of 494 young adults between the ages of 18 and 35 indicated that parental divorce does have a negative impact on romantic beliefs, attitudes toward marriage and divorce, romantic attachments, and relationship characteristics when considered in the context of marriage. Those individuals whose parents divorced reported less positive attitudes toward marriage and more openness toward divorce. Those whose parents divorced reported less idealized romantic beliefs and less of a belief that love will find a way. Those who experienced parental divorce had a more fearful romantic attachment style and reported a lower chance of marriage to their current partner.

The Effects of an Electronic Feedback Sign on Speeding (open access)

The Effects of an Electronic Feedback Sign on Speeding

Although a handful of experiments have utilized indirect feedback in attempts to reduce speeding on roadways, fewer experiments have utilized direct feedback as a means to reduce incidences of speeding. The current study evaluated the effects of direct and individualized feedback provided by a large electronic feedback sign that displayed the speed of oncoming vehicles as they approached the sign along the roadways of a college campus. The effects of the sign were evaluated using a non-simultaneous multiple baseline experimental design employing two control conditions and intervention phase. Each condition was implemented at three sites on the college campus. The results showed that intervention produced significant decreases in both measures of vehicle speeds at each site, relative to measures collected during both control conditions.

The Effects of Labeling and Stigma on the Social Rejection of Striptease Performers (open access)

The Effects of Labeling and Stigma on the Social Rejection of Striptease Performers

This study uses survey data collected from a convenience sample of undergraduate students (N=89). A vignette survey design is employed to measure social rejection of striptease performers compared to a control group. Data is also collected on negative stereotypes held about striptease performers, which are correlated with social rejection. Link and Phelan's conceptualization of the stigma process provides the theoretical framework for this analysis. Findings suggest that striptease performers experience higher levels of social rejection and are perceived more negatively than the control group and that endorsement of negative stereotypes is associated with social rejection.

The Effects of Tests and Praise on Children's Hear-write and See-say Responses. (open access)

The Effects of Tests and Praise on Children's Hear-write and See-say Responses.

Four elementary school children were tested on 120 words containing the short e (e.g., ten, pen) and short a (e.g., tan, pan) sounds. Words were tested in the hear-write (H/W) and see-say (S/S) channels. No programmed consequences were scheduled during baseline (BL) tests 1-3. After BL, an error analysis categorized words based on channel error and topography of error. Praise was delivered during tests 4-6 for correct responses. Children's responses were variable within channel and across channels for a majority of words. By the end of the praise phase, there was a decrease in the number of words with errors, for all children in their error word group. Error topographies began to stabilize for some words during praise.

Effects of Training Accurate Component Strokes Using Response Constraint and Self-evaluation on Whole Letter Writing. (open access)

Effects of Training Accurate Component Strokes Using Response Constraint and Self-evaluation on Whole Letter Writing.

This study analyzed the effects of a training package containing response constraint, self-evaluation, reinforcement, and a fading procedure on written letter components and whole letter writing in four elementary school participants. The effect on accuracy of written components was evaluated using a multiple-baseline-across components and a continuous probe design of components, as well as pre-test, baseline, and post-test measures. The results of this study show that response constraint and self-evaluation quickly improved students' performance in writing components. Fading of the intervention was achieved quickly and performance maintained. Results also show that improvement in component writing improved whole letter and full name writing and letter reversals in the presence of a model were corrected.

Electrochemical Study of Under-Potential Deposition Processes on Transition Metal Surfaces (open access)

Electrochemical Study of Under-Potential Deposition Processes on Transition Metal Surfaces

Copper under-potential deposition (UPD) on iridium was studied due to important implications it presents to the semiconductor industry. Copper UPD allows controlled superfilling on sub-micrometer trenches; iridium has characteristics to prevent copper interconnect penetration into the surrounding dielectric. Copper UPD is not favored on iridium oxides but data shows copper over-potential deposition when lower oxidation state Ir oxide is formed. Effect of anions in solution on silver UPD at platinum (Pt) electrodes was studied with the electrochemical quartz crystal microbalance. Silver UPD forms about one monolayer in the three different electrolytes employed. When phosphoric acid is used, silver oxide growth is identified due to presence of low coverage hydrous oxide species at potentials prior to the monolayer oxide region oxide region.

Employee empowerment: Relationships between location in the hierarchy, span of control, and industry type on perceptions of empowerment.

Access: Use of this item is restricted to the UNT Community
The current study seeks to examine the relationships between perceptions of employee empowerment and perceptions of leadership, span of control, and industry type. Participants were gathered from an archival source employing a high school alumni e-mail group (n = 361) and a survey from 9 organizations (n = 647) and combined into a larger sample (n = 1008). The participants took Bodner's (2005) Assessment of Employee Empowerment and Assessment of Empowering Leadership instruments. Support was found to suggest that people report being less empowered than they believe that top management would report about them. Also, participants reported that their leader was less empowering than they believed top management would report about the leader. Span of control was found to impact perceptions of empowerment. Production workers reported feeling more empowered than workers in service industries. Participants did not report that leaders were more empowering if they were higher in the hierarchy (executive) than lower levels (coach, employee). Also, a respondent's position did not affect the relationship between job type and feelings of empowerment. This study suggests that the organizational design (span of control) and industry type may affect empowerment initiatives, while lower levels of the organization may view empowerment much differently …

Energy-Aware Time Synchronization in Wireless Sensor Networks (open access)

Energy-Aware Time Synchronization in Wireless Sensor Networks

I present a time synchronization algorithm for wireless sensor networks that aims to conserve sensor battery power. The proposed method creates a hierarchical tree by flooding the sensor network from a designated source point. It then uses a hybrid algorithm derived from the timing-sync protocol for sensor networks (TSPN) and the reference broadcast synchronization method (RBS) to periodically synchronize sensor clocks by minimizing energy consumption. In multi-hop ad-hoc networks, a depleted sensor will drop information from all other sensors that route data through it, decreasing the physical area being monitored by the network. The proposed method uses several techniques and thresholds to maintain network connectivity. A new root sensor is chosen when the current one's battery power decreases to a designated value. I implement this new synchronization technique using Matlab and show that it can provide significant power savings over both TPSN and RBS.

English language learners: Does summer school make a difference in young children's literacy scores?

Access: Use of this item is restricted to the UNT Community
Many school districts consider literacy and oral language as a top priority for pre-kindergarten students. In the district under study, pre-kindergarten English language learner (ELL) students are encouraged to attend a special summer school program to increase their oral language ability in English. This study compared three groups of children: ELL students attending summer school v. ELL students not attending summer school v. English speaking students not attending summer school. The students' primary reading inventory scores from the end of pre-kindergarten to the middle of kindergarten in the areas of reading, writing and oral language were compared. As expected, ELLs who attended summer school showed significant growth in oral language development from the beginning of summer school to the end of summer school. While it was hypothesized that ELL students attending summer school would show more improvement in oral language than other children over time, there was no significant difference between summer school and non-summer school children's scores by the middle of kindergarten.
