High School Teachers' Perceptions of Giftedness, Gifted Education, and Talent Development

Description: In the field of gifted education, there is little research on the perceptions of high school teachers of the gifted about giftedness, good gifted education practices, and the nature and needs of gifted learners. The purpose of this study was to form a deeper understanding of how those educators who guide gifted learners out of high school and into adulthood perceive giftedness and gifted education. This qualitative study, conducted in two phases, took place in a large suburban school district with three large high school systems and was focused on the responses of high school teachers to assess their attitudes, feelings, and opinions about the nature and needs of gifted learners using a grounded theory model of analysis. Data collected from the 11 participants in the first phase of the analysis was combined with that collected from the 13 participants in phase two and validated throughout with continual comparison through memoing. Participants reported a general lack of engagement with scholarly work in the gifted education field as well as a dependence on the school district for effective training in classroom practice. Evidence also suggested a view of giftedness among the participants as an inherent quality of some people who needed to be properly trained in the instructional environment. Implications from this study suggest further research, both qualitative and quantitative, needs to focus on clarifying the perception of giftedness among high school teachers as well as how the delivery of effective training to those teachers can be implemented.

Assessing Rainfall Interception by Urban Tree Canopies in Denton, Texas

Description: Rainfall interception is one mechanism by which tree canopies can reduce surface runoff in urban areas. The objectives of this research were to: 1) quantify rainfall interception by urban tree canopies, and 2) determine the influence of vegetation and microenvironmental factors on rainfall interception rates. In the city of Denton, Texas, 30 mature post oak (Quercus stellata) and blackjack oak (Quercus marilandica) trees were selected for study. Trees were assigned to one of three categories: clusters of trees on greenspace (CG), isolated trees on greenspace (IG), and isolated trees surrounded by pavement (IP). Throughfall (the volume of water that travels through the canopy and reaches the soil surface) collectors were placed beneath these trees and rainfall collectors were placed in nearby open areas. Throughfall and rainfall were collected daily from 19 March to 4 July. Interception was calculated as the difference between throughfall and gross rainfall. Over the study period, there were 27 days with measurable rainfall; daily rainfall ranged from 1-51 mm. Over the sampling period, rainfall interception for individual trees ranged from -10% to 49%, indicating high spatial variability in interception. Percent interception was highest for the CG treatment (22.7 ± 3.8 SE), intermediate for IG (27.4 ± 2.3 SE), and lowest for IP (9.1 ± 4.9 SE). Factors like wind exposure, wind-driven rain and overall tree health may help explain this variability. This research will contribute to our knowledge of hydrological fluxes in urban areas and the role of urban green infrastructure in stormwater runoff mitigation.

The West Point Band's Wind Commissioning Project in Celebration of the Bicentennial of the United States Military Academy

Description: The United States Military Academy Band, also known as the West Point Band is the oldest active band in the United States Army and the oldest unit at the United States Military Academy, and is considered to be one of the finest military musical organizations in the world. The band has also been instrumental in facilitating the creation of new works for wind band.As the commissioning of new music has been essential to the expansion of the wind band's repertoire, several major commissioning projects were undertaken in the mid-twentieth century by various organizations, including the West Point Band, the Goldman Band in conjunction with the League of Composers and later the American Bandmasters Association, Kappa Kappa Psi and Tau Beta Sigma, the American Wind Symphony, and the College Band Directors National Association. These commissioning projects and many others have contributed hosts of new quality works to the repertoire of the wind band. The West Point Band's 1952 commissioning project celebrating the Sesquicentennial of the United States Military Academy was among the first of these mid-twentieth century commissioning projects to seek out prominent composers of the day and have them write works for wind band. The project contributed several seminal pieces to the wind band's repertoire, including Morton Gould's Symphony for Band: West Point. In 1996, as tribute to both the Academy and to the earlier commissioning project, the West Point Band sought to celebrate the Academy's 2002 bicentennial in a similar fashion by commissioning well-known composers to contribute substantial wind works. These pieces would be premiered and recorded by the West Point Band over a number of years, including a gala Bicentennial Celebration concert at Carnegie Hall in March 2002. The purpose of this study is to create a consolidated written record of the wind music composed for the West ...

Spanish Diction in Latin American Art Song: Variant Lyric Pronunciations of (s), (ll), and (y)

Description: Latin American art song is a genre primarily of the first half of the twentieth-century, when popular folklore served as the voice and inspiration of many poets and musicians. The nationalist movement served as a means of expression, each Latin American country with its own identity. There is great benefit for singers to study Spanish diction at an academic level, since it is a language already familiar to most U.S.A residents. There is a significant amount of unknown repertoire that would be very useful in the singing studio because of the language's open vowels. This repertoire can also serve as a confidence-builder to young Spanish-speaking singers at the beginning of their training. I will be focusing on the (s), (ll), and (y) sounds as pronounced in the diverse regions of Latin America; in particular, why they matter when coaching singers, and the articulators involved in each. The purpose of this study is to discuss diction differences in the repertoire, expound on its benefits for voice pedagogy, all while informing about varied options for recital programming.

The Persuasive Power of Ridicule: A Critical Rhetorical Analysis of Gender and Humor in U.S. Sitcoms

Description: The serious investigation of humor's function in society is an emerging area of research in critical humor studies, a "negative" subsect of the extensive and "positive" research that assumes humor's goodness. Using Michael Billig's theory of ridicule as a framework, this study explored how humor operated to discipline characters who broke social norms or allowed characters to rebel against those norms. Layering this with gender performative theory, the study also investigated how different male and female characters used ridicule and were subject to it themselves. After examining ridicule in The Big Bang Theory, 2 Broke Girls, and The Odd Couple using a critical rhetorical analysis, the findings revealed that disciplinary ridicule was used more overtly throughout all three programs, while potentially rebellious ridicule emerged in only a few scenes. In addition, men were overwhelmingly the subjects of disciplinary ridicule, although women found themselves as subjects throughout all three programs as well. The discursive ridiculing of non-normative bodies constructed and maintained social norms about gender and sexuality, thereby uninviting these bodies from participating in society.

Characteristics of Mothers among Counselor Education Faculty

Description: Pre-tenured faculty in higher education and as well as mothers have reportedly struggled with low wellness levels, high demands, little social support, and an imbalance of work and home life. Mothers in higher education and in counselor education have reported struggling with work-life balance, high scholarly productivity, and long hours as well as the emotional and physical energy demands of working with counselors-in-training. A search of the professional literature revealed a paucity of quantitative research regarding demographic characteristics, wellness levels, and social support levels of mothers among counselor education faculty (MCEs). Participants for this study were faculties of counselor education programs recruited from the Holland List of Counseling Programs and from the Council for Accreditation of Counseling and Related Educational Programs online directory. A total of 180 MCEs participated (aged 29-63, with mean age 40.6 years; 83% Caucasian, 8% other, 5% African American, 3% Hispanic, <1% Asian). Results showed that faculty rank did not account for a significant difference among wellness scores of MCEs and that reported social support, tenure or non-tenure track, number of children in the care of MCEs, number of children under age 8, number of publications, and teaching workload accounted for 14% of the variance in wellness levels of MCEs. Specifically, reported higher teaching workload (β = -.194, rs2 = .35, p = .012) and higher social support (β = -.258, rs2 = .36, p = <.001) were found to be significant predictors of lower wellness levels among MCEs, both with small effects. Based on these results, MCEs may benefit from advocating that their departments and universities adapt to their unique needs to improve their levels of wellness and social support through mentoring, which, in turn, may result in not only their own increased productivity but also their students' increased wellness levels.

Impact of the Clery Act: An Examination of the Relationship between Clery Act Data and Recruitment at Private Colleges and Universities

Description: The problem this study addressed is the relationship between Clery Act crime data and student recruitment at private colleges and universities. For this quantitative study, I used secondary data from the Department of Education and the Delta Cost Project (2013) to conduct ordinary least squares regression analyses to determine the predictive ability of institutional characteristics, specifically the total number of crime incidents reported in compliance with the Clery Act, on the variance in number of applications and applicant yield rate at private four-year institutions in the United States. Findings showed that the total number of reported incidents was a significant positive predictor of the total number of applications. Conversely, findings also showed that the total number of incidents had a significant negative impact on institutional yield rates. An implication of this study is that although crime statistics required by the Clery Act may not serve as variables used in the student application process, they are part of numerous variables used in the student's decision to enroll at a particular school. The findings highlight the importance of prioritizing and investing in safety and security measures designed to reduce rates of crime; especially for private, enrollment-driven institutions of higher education.

Extracting Useful Information from Social Media during Disaster Events

Description: In recent years, social media platforms such as Twitter and Facebook have emerged as effective tools for broadcasting messages worldwide during disaster events. With millions of messages posted through these services during such events, it has become imperative to identify valuable information that can help the emergency responders to develop effective relief efforts and aid victims. Many studies implied that the role of social media during disasters is invaluable and can be incorporated into emergency decision-making process. However, due to the "big data" nature of social media, it is very labor-intensive to employ human resources to sift through social media posts and categorize/classify them as useful information. Hence, there is a growing need for machine intelligence to automate the process of extracting useful information from the social media data during disaster events. This dissertation addresses the following questions: In a social media stream of messages, what is the useful information to be extracted that can help emergency response organizations to become more situationally aware during and following a disaster? What are the features (or patterns) that can contribute to automatically identifying messages that are useful during disasters? We explored a wide variety of features in conjunction with supervised learning algorithms to automatically identify messages that are useful during disaster events. The feature design includes sentiment features to extract the geo-mapped sentiment expressed in tweets, as well as tweet-content and user detail features to predict the likelihood of the information contained in a tweet to be quickly spread in the network. Further experimentation is carried out to see how these features help in identifying the informative tweets and filter out those tweets that are conversational in nature.

When the Levee Breaks: An SEM Approach to Understanding the Narrative and the Anxiety-Buffer Disruption on PTSD Symptoms

Description: The purpose of the present study was to assess if combining the two frameworks would account for more variance in PTSS than could be accounted for using the frameworks separately. An online community sample from Amazon.com's Mechanical Turk (N = 437), who reported experiencing a prior traumatic event, completed measures that reflected the constructs of narrative centrality, negative affectivity, and death concerns, along with a measure of PTSS. PTSS was regressed on the latent variables of death concerns, narrative centrality, and negative affectivity, along with the latent variable interactions between narrative centrality*death concerns and narrative centrality*negative affectivity. Death concerns was not be predictive of PTSS, whereas narrative centrality and negative affectivity were found to uniquely and interactively account for 77% of the variance in PTSS. Death concerns was found to be a separate construct from negative affectivity. The implications of these findings for the two frameworks are discussed along with future directions. By considering aspects of narrative centrality and negative affectivity, substantial portions of PTSS can be accounted for.

Consequences of Coworker Bullying: A Bystander Perspective

Description: Previous research on workplace bullying primarily focuses on two main actors – the bully and the victim – while neglecting a third actor: the bystander of the bullying. The prevalence of workplace bullying is increasing across organizations, resulting in more employees becoming subjected to the effects of workplace bullying. Furthermore, witnessing coworker-on-coworker bullying is likely to influence the relationships that the bystander has with the two coworkers involved in the bullying episode. Two areas are proposed to investigate their effect on the coworker bystander: coworker interpersonal justice and personal identification with coworkers. Coworker interpersonal justice involves the perceived fairness between coworkers, while personal identification refers to how these bystanders identify with the specific actors of the bullying event. In addition to work-related outcomes, bystanders are affected at a personal level. That is, being exposed to bullying situations causes these bystanders to alter their anxiety levels and their core affect, with core affect being a precursor to moods and emotions. In addition to the aforementioned outcomes of witnessing a coworker bullying incident, there are also contextual aspects which may influence these relationships. Personal-level factors, such as a bystander's empathy and sense of coherence (i.e., coping mechanisms), may influence the effect of witnessing a coworker being bullied. Similarly, the gender of the victim in relation to the gender of the bystander may also play a role. Using affective events theory, I investigate how witnessing coworker bullying in the workplace effects bystanders. This research employs a 2 x 2 experimental design with multi-wave data collection and an in-person lab session to test the proposed hypotheses. AET is operationalized by creating a fictional coworker bullying situation in which observers are either exposed to the bullying situation or not. This research offers several contributions to the management literature as well as to practitioners. First, it ...

A Motivic Analysis and Performance Practices of "Akrodha" (1998) by Kevin Volans, including Comparative Analyses of "She Who Sleeps with a Small Blanket" (1985) and "Asanga" (1997)

Description: This dissertation presents an analysis of Akrodha (1998), a multiple percussion solo in two movements, composed by Kevin Volans. The analysis is focused on the motivic content and subsequent iterations written within the tempos that provide the structural form of the piece. The structural tempos are supported by the presence of various motifs that serve as the tempos' characteristic traits, thereby giving the tempos more tangibility. As the work develops, these motifs reappear either as note-for-note reiterations or as variations that still maintain the unique qualities of the motifs. For comparison, similar analyses of Mr. Volans' other multiple percussion solos, She Who Sleeps with a Small Blanket (1985) and Asanga (1997), are also presented to further explore Mr. Volans' use of motifs as they relate to structural tempos. In addition, a comprehensive performance practice of Akrodha is presented based on a synthesis of considerations and methods from individuals involved in the piece's development and early performances. These include Dr. Volans himself, Jonny Axelsson (for whom Akrodha was written), and Robyn Schulkowsky (for whom She Who Sleeps with a Small Blanket and Asanga were written), as well as the author's personal experiences. This dissertation provides a deeper understanding of Akrodha for the scholar and provides performance guidance for the performer to enhance the ability to replicate the musical spirit of Kevin Volans' compositional intentions.

Becoming Successful in Education: Beating the Odds, Despite a Background Entrenched in Poverty

Description: The purpose of this study was to investigate the impact of three relationships on academic achievement in mathematics in students of poverty. The three factors that were examined included: teacher-student relationships, parent-student relationships and peer- student relationships. The driving question for the research was as follows: Do external factors such as teacher-student relationships, parent-student relationships and peer-student relationships lead to academic success for students of poverty? The study employed a non-experimental, quantitative approach and utilized longitudinal data from a national database High School Longitudinal Study (HSLS) used a sample of 944 public and private high schools across the USA. A total 0f 28,240 were represented in the survey. Of these 28,240 students, 2641 were used in this study as identified by parental income below the poverty threshold. The outcome of the study indicated that there was little or no correlation between the three relationships and mathematics achievement (academic success). Correlations between the dependent variable (math achievement) and the independent variables even though some were statistically significant their weights had no concrete significance. The study recommends that several initiatives can be instated in schools to support and enhance academic achievement in students of poverty.

Protests in China: Why and Which Chinese People Go to the Street?

Description: This research seeks to answer why and which Chinese people go to the street to protest. I argue that different sectors of Chinese society differ from each other regarding their tendencies to participate in protest. In addition to their grievances, the incentives to participate in protest and their capacities to overcome the collective action problem all needed to be taken into account. Using individual level data along with ordinary binary logistic regression and multilevel logistic regression models, I first compare the protest participation of workers and peasants and find that workers are more likely than peasants to participate in protests in the context of contemporary China. I further disaggregate the working class into four subtypes according to the ownership of the enterprises they work for. I find that workers of township and village enterprises are more likely than workers of state-owned enterprises to engage in protest activities, while there is no significant difference between the workers of domestic privately owned enterprises and the workers of foreign-owned enterprises regarding their protest participation. Finally, I find that migrant workers, which refers to peasants who move to urban areas in search of jobs, are less likely than urban registered workers to participate in protests.

Examining Help-Seeking Intentions of Chinese Individuals: A Path Analysis

Description: Utilizing the theory of planned behavior, I examined the variables that affect Chinese individuals' help-seeking intention. A total of 251 Chinese individuals participated in this study. Results showed that the variables in the theory of planned behavior accounted for 16% of the variance in help-seeking intention. Specifically, attitude (r = .22, p < .001) and perceived behavioral control (r = .22, p < .001) were found to be significant predictors of help-seeking intention. Based on these results, mental health professionals can design outreach interventions, such as psychoeducational programs, to improve Chinese individuals' help-seeking attitude and perceived behavioral control in an attempt to increase mental health service utilization. Additionally, counselors can discuss with clients' their attitude and perceived behavioral control regarding seeking counseling in an attempt to assist clients in being committed to the counseling process.

Structure Evolution and Nano-Mechanical Behavior of Bulk Metallic Glasses and Multi-Principal Element Alloys

Description: Bulk metallic glasses and multi-principal element alloys represent relatively new classes of multi-component engineering materials designed for satisfying multiple functionalities simultaneously. Correlating the microstructure with mechanical behavior (at the microstructural length-scales) in these materials is key to understanding their performance. In this study, the structure evolution and nano-mechanical behavior of these two classes of materials was investigated with the objective of fundamental scientific understanding of their properties. The structure evolution, high temperature nano-mechanical behavior, and creep of two Zr-based alloys was studied: Zr41.2Ti13.8Cu12.5Ni10.0Be22 (Vitreloy1) and Zr52.5Ti5Cu17.9Ni14.6All0 (Vitreloy105). Devitrification was found to proceed via the formation of a metastable icosahedral phase with five-fold symmetry. The deformation mechanism changes from inhomogeneous or serrated flow to homogenous flow near 0.9Tg, where Tg is the glass transition temperature. The creep activation energy for Vitreloy1 and Vitreloy105 were 144 kJ/mol and 125 kJ/mol, respectively in the range of room temperature to 0.75Tg. The apparent activation energy increased drastically to 192 kJ/mol for Vitreloy1 and 215 kJ/mol for Vitreloy105 in the range of 0.9Tg to Tg, indicating a change in creep mechanism. Structure evolution in catalytic amorphous alloys, Pt57.5Cu14.7Ni5.3P22.5 and Pd43Cu27Ni10P20, was studied using 3D atom probe tomography and elemental segregation between different phases and the interface characteristics were identified. The structure evolution of three multi-principal element alloys were investigated namely CoCrNi, CoCrFeMnNi, and Al0.1CoCrFeNi. All three alloys formed a single-phase FCC structure in as-cast, cold worked and recrystallized state. No secondary phases precipitated after prolonged heat treatment or mechanical working. The multi-principal element alloys showed less strain gradient plasticity compared to pure metals like Ni during nano-indentation. This was attributed to the highly distorted lattice which resulted in lesser density of geometrically necessary dislocations (GNDs). Dislocation nucleation was studied by low load indentation along with the evaluation of activation volume and activation energy. This was ...

Exploring Simscape™ Modeling for Piezoelectric Sensor Based Energy Harvester

Description: This work presents an investigation of a piezoelectric sensor based energy harvesting system, which collects energy from the surrounding environment. Increasing costs and scarcity of fossil fuels is a great concern today for supplying power to electronic devices. Furthermore, generating electricity by ordinary methods is a complicated process. Disposal of chemical batteries and cables is polluting the nature every day. Due to these reasons, research on energy harvesting from renewable resources has become mandatory in order to achieve improved methods and strategies of generating and storing electricity. Many low power devices being used in everyday life can be powered by harvesting energy from natural energy resources. Power overhead and power energy efficiency is of prime concern in electronic circuits. In this work, an energy harvester is modeled and simulated in Simscape™ for the functional analysis and comparison of achieved outcomes with previous work. Results demonstrate that the harvester produces power in the 0 μW to 100 μW range, which is an adequate amount to provide supply to low power devices. Power efficiency calculations also demonstrate that the implemented harvester is capable of generating and storing power for low power pervasive applications.

Applied Use of Video Modeling in Educational and Clinical Settings: A Survey of Autism Professionals

Description: Individuals with autism spectrum disorder (ASD) display deficits in communication and social interaction that can impact their ability to function in daily environments. To remediate these deficits, it is critical for professionals to use effective interventions. While there are many evidence-based practices (EBPs) identified for ASD (e.g., video modeling), the adoption of these EBPs may not occur automatically. Existing research suggests professionals have a generally favorable impression of video modeling. However, little research has examined opinions and applied use of video modeling, which was the purpose of the present study. Using survey methodology, data were collected from 510 professionals in various disciplines (e.g., special educators, speech-language pathologists [SLPs], and behavior analysts [BCBAs]). Data were analyzed primarily via factor analysis and multiple regression. Factor analysis was used to examine the underlying structure of the instrument, revealing two predominant factors: (1) interest in and (2) perceived accessibility of video modeling. Multiple regression was used to examine which demographic characteristics (e.g., age and years of experience) were associated with each factor. Results indicated that BCBAs and SLPs perceived video modeling as more accessible. In terms of interest, professionals who worked with preschool-aged students, who worked in a suburban location, and who had an extended family member with ASD showed higher interest in video modeling. Implications for practice and future research are discussed.

Catastrophe in Permanence: Benjamin's Natural History of Environmental Crisis

Description: Walter Benjamin warned in 1940 of a certain inconspicuous threat to political thinking, not least of all to materialism, that takes progress as an historical norm. Implicit in this conception is what he describes as an empty continuum of time along which the prevailing tradition chronicles its own mythic development and drains everyday life of genuine historical experience. The myth of progressive history advances insidiously today in consumeristic and technocratic attempts at reconciling cultural imagery with organic nature. In this dissertation, I pursue the contradictions of such images as they crystallize around the natural history of twenty-first century commodity society, where promises of ecological remediation, sustainable urban development, and climate change mitigation have yet to introduce a true crisis of historical experience to the ongoing environmental crisis of capitalism. A more radical way of seeing the cultural representation of nature would, I argue, penetrate its mythic determination by market forces and bear witness to the natural-historical ruins and traces that constitute, in Benjamin's terms, a single "catastrophe" where others perceive historical continuity. I argue that Benjamin's critique of progress is instructive to interpreting those utopian dreams, ablaze in consumer life and technological fantasy, that recent decades of growing environmental concern have channeled into the recovery of an experience of the natural world. His dialectics of nature and alienated history confront the wish-image of organic abundance with the transience of its appropriated expression in the commodity-form. Drawing together this confrontation with a varied literature on collective memory, nature, and the city, I suggest that our poverty of experience is more than simply a technical, economic, or even ecological problem, but rather follows from the commodification of history itself. The goal of this work is to reflect upon the potentiality of communal politics that subsist not in rushing headlong into a progressive ...

Reconstructing Identity through Urban Community Agriculture: How Refugees Confront Displacement, Food Insecurity, and Othering through Community Farming

Description: Ethnic and religious conflict, and the deepening of capitalism have led to global diaspora at unprecedented levels. The United Nations High Commissioner for Refugees reported that as of 2015, 1 in every 122 persons worldwide were either a refugee, internally displaced, or seeking asylum. The U.S. currently admits the largest number of refugees worldwide. However, policies fail to reflect the multitude of elements that constitute successful resettlement. Moreover, many refugees come from farming backgrounds and are forced to migrate to a landless urban environment, where their skill sets may not be utilized and farm land is not available. I argue that existing resettlement processes are embedded in logics and practices that alienate humans from nature and from each other through competition, isolation, and placeless environments. Through an exploration in concepts of urban agriculture, place-making, identity, and otherness, and illuminating the experiences of resettled refugees involved in a community gardening project in Fort Worth, Texas, show how the urban refugee garden provides the individual a space to narrate an identity, and to resist industrial agriculture and labor outside their industry. Exploring best practices in resettlement should be a priority to governments, politicians, and communities involved in the process and highlight the reasons to advocate these types of resettlement alternatives.

Development of an Outcome Measure for Use in Psychology Training Clinics

Description: The ability to monitor client change in psychotherapy over time is vital to quality assurance in service delivery as well as the continuing improvement of psychotherapy research. Unfortunately, there is not currently a comprehensive, affordable, and easily utilized outcome measure for psychotherapy specifically normed and standardized for use in psychology training clinics. The current study took the first steps in creating such an outcome measure. Following development of an item bank, factor analysis and item-response theory analyses were applied to data gathered from a stratified sample of university (n = 101) and community (n = 261) participants. The factor structure did not support a phase model conceptualization, but did reveal a structure consistent with the theoretical framework of the research domain criteria (RDoC). Suggestions for next steps in the measure development process are provided and implications discussed.

Design, Modeling, and Experiment of a Piezoelectric Pressure Sensor based on a Thickness-Shear Mode Crystal Resonator

Description: This thesis presents the design, modeling, and experiment of a novel pressure sensor using a dual-mode AT-cut quartz crystal resonator with beat frequency analysis based temperature compensation technique. The proposed sensor can measure pressure and temperature simultaneously by a single AT-cut quartz resonator. Apart from AT-cut quartz crystal, a newly developed Langasite (LGS) crystal resonator is also considered in the proposed pressure sensor design, since LGS can operate in a higher temperature environment than AT-cut quartz crystal. The pressure sensor is designed using CAD (computer aided design) software and CAE software - COMSOL Multiphysics. Finite element analysis (FEA) of the pressure sensor is performed to analyze the stress- strain of the sensor's mechanical structure. A 3D printing prototype of the sensor is fabricated and the proposed sensing principle is verified using a force-frequency analysis apparatus. Next to the 3D printing model verification, the pressure sensor with stainless steel housing has been fabricated with inbuilt crystal oscillator circuit. The oscillator circuit is used to excite the piezo crystal resonator at its fundamental vibrational mode and give the frequency as an output signal. Based on the FEA and experimental results, it has been concluded that the maximum pressure that the sensor can measure is 45 (psi). The pressure test results performed on the stainless steel product shows a highly linear relationship between the input (pressure) and the output (frequency).

Recidivism among Determinately Sentenced Juvenile Homicide Offenders in Texas

Description: Juvenile homicide offenders pose a significant risk to society considering the severity of the crime, yet this population of delinquents receives little attention in terms of recidivism research. This study examined the recidivism outcomes of a group of 256 determinately sentenced homicide offenders in Texas. Each of these juveniles had be confined to and subsequently release from the Texas Youth Commission, and were followed for three years following release. The aim of this research study was to distinguish recidivists from non-recidivists across demographic, delinquent history, and risk factor measures. These same measures were then used to predict recidivism among the entire sample. Overall, the measures of race, gender, and previous delinquent adjudications emerged significant. First, Black youth were significantly more likely to recidivate than both Hispanic and White youth. Additionally, recidivism among males was significantly greater than non-recidivism among males. In contrast, there were fewer females in recidivist group than the non-recidivist group. Finally, youth with a greater number of previous delinquent adjudications were significantly more likely to recidivate, and the risk of recidivism increased as the number of previous adjudications increased. These findings are consistent with previous literature and indicate that these factors are prevalent in analyzing the recidivist behavior of determinately sentenced juvenile homicide offenders.
