Riding Lucifer's Line: Ranger Deaths Along the Texas-mexico Border
Access:
Use of this item is restricted to the UNT Community
The Texas-Mexico border is trouble. Haphazardly splashing across the meandering Rio Grande into Mexico is—or at least can be—risky business, hazardous to one’s health and well-being. Kirby W. Dendy, the Chief of Texas Rangers, corroborates the sobering reality: “As their predecessors for over one hundred forty years before them did, today’s Texas Rangers continue to battle violence and transnational criminals along the Texas-Mexico border.” In Riding Lucifer’s Line, Bob Alexander, in his characteristic storytelling style, surveys the personal tragedies of twenty-five Texas Rangers who made the ultimate sacrifice as they scouted and enforced laws throughout borderland counties adjacent to the Rio Grande. The timeframe commences in 1874 with formation of the Frontier Battalion, which is when the Texas Rangers were actually institutionalized as a law enforcing entity, and concludes with the last known Texas Ranger death along the border in 1921. Alexander also discusses the transition of the Rangers in two introductory sections: “The Frontier Battalion Era, 1874-1901” and “The Ranger Force Era, 1901-1935,” wherein he follows Texas Rangers moving from an epochal narrative of the Old West to more modern, technological times. Written absent a preprogrammed agenda, Riding Lucifer’s Line is legitimate history. Adhering to facts, the author is …

Evaluation of Law Enforcement and the Court System in Texas: Perspectives of Adult Protective Services Case Managers
The purpose of this study was to examine perceptions of Texas Adult Protective Services (APS) case managers (CM) in regard to their relationships with the law enforcement community and area courts. The sample consisted of 138 Texas APS CMs. The survey measured respondents' perceived strengths and weaknesses of their relationships with both the law enforcement community and with area courts. Items also included respondents' interest in receiving additional training and their perceptions of level of job-readiness of newly hired APS CMs. Data were analyzed quantitatively using SAS. Findings of the survey revealed high ratings of perceived teamwork on the part of the CM are associated with high relationship ratings with both area courts and law enforcement. Findings also revealed that high ratings of perceived autonomy on the part of the CM are associated with lower relationship ratings with law enforcement personnel but not with area courts.

Early and Current Family Environment Among Inpatient Trauma Survivors: Associations with Multi-type Abuse and Sexual Orientation
The present study is an exploratory analysis of associations among sexual orientation, childhood abuse, and characteristics of both early and current family environment in a sample of 80 inpatient trauma survivors. Participants were administered a background information questionnaire, Dissociative Disorders Interview Schedule, the Family Environment Scale and other instruments not analyzed in the current study. Multi-type abuse was significantly associated with low expressiveness and independence and high control in the early family, but no associations emerged with current family characteristics. Results suggest that the intergenerational transmission of family organization and moral-religious orientation occurred in the entire sample, and the transmission of family conflict patterns occurred only in the L/G/B group. Overall, participants perceived improvements in their current family environments compared to their early family environments. Findings yield support for the sexual minority stress model and mixed support for the intergenerational transmission of family characteristics.

The Girl Disappeared: the Prostitute of La Isla De Santa Flora
The novella, The Girl Disappeared, focuses on the life of Emalia, a street kid from Mexico. She is taken from the streets of Veracruz and forced into a life of prostitution on the fictitious island of La Isla de Santa Flora. The primary conflict that drives the action of the story is her pending choice between escaping her life of slavery and saving another young woman who is on the verge of being forced into a life of prostitution as well. The novella, as a literary piece, dwells on the question of character agency and explores the multilayered nature of code switching. Language for these women becomes a tool in their struggle against their captives and a means of self-preservation, or sanctuary, as they use their growing bilingualism to foment a limited agency, to act in their own defense.

Analytical Model of Cold-formed Steel Framed Shear Wall with Steel Sheet and Wood-based Sheathing
The cold-formed steel framed shear walls with steel sheets and wood-based sheathing are both code approved lateral force resisting system in light-framed construction. In the United States, the current design approach for cold-formed steel shear walls is capacity-based and developed from full-scale tests. The available design provisions provide nominal shear strength for only limited wall configurations. This research focused on the development of analytical models of cold-formed steel framed shear walls with steel sheet and wood-based sheathing to predict the nominal shear strength of the walls at their ultimate capacity level. Effective strip model was developed to predict the nominal shear strength of cold-formed steel framed steel sheet shear walls. The proposed design approach is based on a tension field action of the sheathing, shear capacity of sheathing-to-framing fastener connections, fastener spacing, wall aspect ratio, and material properties. A total of 142 full scale test data was used to verify the proposed design method and the supporting design equations. The proposed design approach shows consistent agreement with the test results and the AISI published nominal strength values. Simplified nominal strength model was developed to predict the nominal shear strength of cold-formed steel framed wood-based panel shear walls. The nominal shear …

Cold-formed Steel Framed Shear Wall Sheathed with Corrugated Sheet Steel
Incombustibility is one important advantage of the sheet steel sheathed shear wall over wood panel sheathed shear wall. Compared to shear wall sheathed with plywood and OSB panel, shear wall sheathed with flat sheet steel behaved lower shear strength. Although shear wall sheathed with corrugated sheet steel exhibited high nominal strength and high stiffness, the shear wall usually behaved lower ductility resulting from brittle failure at the connection between the sheathing to frames. This research is aimed at developing modifications on the corrugated sheathing to improve the ductility of the shear wall as well as derive practical response modification factor by establishing correct relationship between ductility factor ? and response modification factor R. Totally 21 monotonic and cyclic full-scale shear wall tests were conducted during the winter break in 2012 by the author in NUCONSTEEL Materials Testing Laboratory in the University of North Texas. The research investigated nineteen 8 ft. × 4 ft. shear walls with 68 mil frames and 27 mil corrugation sheet steel in 11 configurations and two more shear walls sheathed with 6/17-in.OSB and 15/32-in. plywood respectively for comparison. The shear walls, which were in some special cutting arrangement patterns, performed better under lateral load conditions according …

Geoarchaeological Analysis of Two New Test Pits at the Dmanisi Site, Republic of Georgia
This thesis presents the results of geoarchaeological investigations conducted at two new test pits, M11 and M12, at the paleoanthropological site of Dmanisi during the 2012 field season. This research is important for understanding the site formation processes occurring along the north-south axis of the Dmanisi site and how that affects the chronostratigraphic sequence and interpretation of archaeological materials here. With these excavations we can build a stronger interpretation for how broader areas of this site formed and changed both geologically and archaeologically. The geologic results of this study indicate that changes in sediment deposition and development episodes can affect interpretations of how long these sediments accumulated, how likely bones are to preserve, as well as how secondary gravel deposition can influence several archaeological interpretations. The archaeological results suggest that there could have been changes in occupation intensity between the stratum A and B phases although different rates of sediment deposition and surface stability could affect such artifact accumulations. In addition, during the stratum B phase there appears to be little change in artifact procurement behaviors and reduction characteristics by these hominins. The overall results of this research indicate that geologic factors should be addressed and cautions should be taken …

Layout-accurate Ultra-fast System-level Design Exploration Through Verilog-ams
This research addresses problems in designing analog and mixed-signal (AMS) systems by bridging the gap between system-level and circuit-level simulation by making simulations fast like system-level and accurate like circuit-level. The tools proposed include metamodel integrated Verilog-AMS based design exploration flows. The research involves design centering, metamodel generation flows for creating efficient behavioral models, and Verilog-AMS integration techniques for model realization. The core of the proposed solution is transistor-level and layout-level metamodeling and their incorporation in Verilog-AMS. Metamodeling is used to construct efficient and layout-accurate surrogate models for AMS system building blocks. Verilog-AMS, an AMS hardware description language, is employed to build surrogate model implementations that can be simulated with industrial standard simulators. The case-study circuits and systems include an operational amplifier (OP-AMP), a voltage-controlled oscillator (VCO), a charge-pump phase-locked loop (PLL), and a continuous-time delta-sigma modulator (DSM). The minimum and maximum error rates of the proposed OP-AMP model are 0.11 % and 2.86 %, respectively. The error rates for the PLL lock time and power estimation are 0.7 % and 3.0 %, respectively. The OP-AMP optimization using the proposed approach is ~17000× faster than the transistor-level model based approach. The optimization achieves a ~4× power reduction for the OP-AMP …
