Evaluation of Law Enforcement and the Court System in Texas: Perspectives of Adult Protective Services Case Managers (open access)

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 (open access)

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 (open access)

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 (open access)

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 (open access)

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 (open access)

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 (open access)

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 …

The Strategic and Operational Debate Over Operation Anvil: the Allied Invasion of Southern France in August, 1944 (open access)

The Strategic and Operational Debate Over Operation Anvil: the Allied Invasion of Southern France in August, 1944

In August, 1944, the Allies embarked on one of the "two supreme operations of 1944," Operation Anvil/Dragoon. It is an operation that almost did not happen. Envisioned as a direct supporting operation of Overlord, Anvil soon ran into troubles. Other operations taking away resources away from Anvil in addition to opposition from the highest levels of Allied command threatened Anvil. This thesis chronicles the evolution of this debate, as well as shed light on one of the most overlooked and successful operations the Allies embarked on in World War II.

Derivation of the Thematic Material and Intervallic Gestures From the Main Theme in Fantasia Carioca By Sérgio Assad (open access)

Derivation of the Thematic Material and Intervallic Gestures From the Main Theme in Fantasia Carioca By Sérgio Assad

The quantity of classical guitar literature reached a new peak late in the twentieth century with many famous guitarists publishing their own works for solo classical guitar. This increase in the published guitar literature resulted in a decline of the relative analytical discussions of contemporary guitar works. Sérgio Assad is a perfect example of an active guitarist/composer whose works are frequently performed in guitar recitals and yet very little discussion has been provided attempting to gain a deeper understanding of his compositional language. The purpose of this study is to two-fold: first, to show that Fantasia Carioca (1994) is a very carefully organized work and includes an intricate network of thematic material developed through a spectrum of intervallic gestures, of which all derive from the main theme of the piece; second, to provide a deeper insight into the compositional language of Sérgio Assad through a demonstration of different compositional procedures to which the composer resorts. This one-movement piece reveals a high level of organization present in Sérgio Assad's style. The entire thematic material is carefully derived from the main theme. Each thematic unit shows a set of predetermined characteristics that allow these units to react to particular textures and situations. …

Pasados Fragmentados:la Representación Teatral Del Robo De Niños En Las Dictaduras Española Y Argentina En Obras De Laila Ripoll Y Patricia Suárez

This study examines the theatrical representation of the stealing of children during the last dictatorships in Spain and in Argentina in Laila Ripoll's Los niños perdidos and Patricia Suárez's Astianacte: una máscara del amor under the lenses of the concepts of trauma, myth and memory. Following the theories suggested by Freud, Adorno, Whitehead, Reyes Mate and others, the first chapter discusses the representation of the psychological traumas left by the dictatorial practices left not only on the minds of individuals but also on both nations as whole entities. While Ripoll invites her audience to reflect upon the consequences of the Spanish Civil War and franquism, Patricia Suárez urges her spectators to doubt about their own identity if they were born during the last dictatorship in Argentina. In chapter two, the concepts advanced by Barthes, Reig Tapia and Moreno-Nuño help explore the ways in which the playwrights condemn the legitimizing myths that gave birth to these dictatorial regimes. Both authors subvert these fictional stories, mainly by the use of sarcasm and humor. By means of the concepts of memory supported by Benjamin, Todorov, Nora and Juliá, the third chapter examines the need to let the traditionally silenced voices tell their version …

Finding Meaning in Context Using Graph Algorithms in Mono- and Cross-lingual Settings (open access)

Finding Meaning in Context Using Graph Algorithms in Mono- and Cross-lingual Settings

Making computers automatically find the appropriate meaning of words in context is an interesting problem that has proven to be one of the most challenging tasks in natural language processing (NLP). Widespread potential applications of a possible solution to the problem could be envisaged in several NLP tasks such as text simplification, language learning, machine translation, query expansion, information retrieval and text summarization. Ambiguity of words has always been a challenge in these applications, and the traditional endeavor to solve the problem of this ambiguity, namely doing word sense disambiguation using resources like WordNet, has been fraught with debate about the feasibility of the granularity that exists in WordNet senses. The recent trend has therefore been to move away from enforcing any given lexical resource upon automated systems from which to pick potential candidate senses,and to instead encourage them to pick and choose their own resources. Given a sentence with a target ambiguous word, an alternative solution consists of picking potential candidate substitutes for the target, filtering the list of the candidates to a much shorter list using various heuristics, and trying to match these system predictions against a human generated gold standard, with a view to ensuring that the …

Bioconcentration and Morphological Effects of Triclosan on Three Species of Wetland Plants (open access)

Bioconcentration and Morphological Effects of Triclosan on Three Species of Wetland Plants

Triclosan (TCS) is an antimicrobial compound found in several types of common household products. After being washed down the drain, TCS will then end up in the local watershed. Although numerous studies have been conducted to evaluate the fate and effects of TCS in aquatic environments, there have been no studies evaluating the role arbuscular mycorrhizal fungi (AM) play in a plants response to TCS exposure. Three species of wetland plants native North Texas were inoculated with AM spores and exposed to 0, 0.4 g/L and 4.0 g/L TCS concentrations. Root morphology of E. prostrata and S. herbacea showed AM and exposure responses. S. herbacea produced the greatest amounts biomass and TCS bioaccumulation, in all but one treatment. It also displayed opposing results to E. prostrata in measures of root length, root surface area, relative root mass, relative shoot mass and shoot:root ratio. TCS root tissue concentrations increased with increased exposures for both E. prostrata and S. herbacea. Even though E. prostrata had the lowest levels in each measure of biomass production, it had the highest amount of root TCS bioaccumulation in the AM inoculated 4.0 g/L treatment. H. laevis was between the other two species in terms of biomass …
