Evaluation of a Behavior Skills Package to Teach Caregivers to Manage Disruptive Behavior during Medical and Dental Appointments (open access)

Evaluation of a Behavior Skills Package to Teach Caregivers to Manage Disruptive Behavior during Medical and Dental Appointments

Adults with developmental disabilities that live in large residential settings experience complications due to problem behavior when attending routine medical/dental appointments. This may result in sedation for clients for even the most routine medical/dental appointments. The purpose of this project was to develop a comprehensive staff training program that incorporated best practices to teach direct-support professionals behavior management techniques and best practices for transporting clients to and from routine medical/dental appointments. 4 direct-support professionals at a large residential care facility participated in this project. Multiple probes were conducted utilizing standard role-play exercises to evaluate caregiver acquisition of 16 specific skills related to client information, best practices for client transport, and behavior management. The results indicated that behavior skills training (BST) resulted in caregiver acquisition of all 16 skills during role-play exercises.

College Readiness and Dual Credit Participation of Alternative High School Students (open access)

College Readiness and Dual Credit Participation of Alternative High School Students

The purpose of this study was to explore the extent to which alternative schools add value to the college readiness of their students, as well as to measure the capacity of alternative school students to successfully complete dual credit courses while enrolled at the alternative school. This mixed methods study utilized an exploratory approach with a descriptive research design to explore the extent to which alternative schools produce college-ready students. The Texas Success Initiative Assessment was used to measure participants' academic readiness levels in mathematics, reading, and writing. Additionally, participants had the opportunity to provide their own perspectives on their college readiness levels through a student survey and semi-structured face-to-face interview. The results of this study reveal that the college readiness levels of alternative high school students varied across academic areas. Of the tested participants, 41.1% were college ready in reading, 52.1% in writing, and 16.7% in mathematics. Additionally, the findings reveal that dual credit course participation was not a viable option because of course prerequisites and the amount of time needed to complete dual credit courses. Results of this study expand on the literature to provide a better understanding of the effectiveness of alternative school programs, the college readiness …

Return to Sport: Improving Athletes' Confidence and Mindset Post-ACL Surgery (open access)

Return to Sport: Improving Athletes' Confidence and Mindset Post-ACL Surgery

This study explored the impact of three psychological interventions over seven weeks - goal setting (GS), GS and imagery (IM), and GS and mindful self-compassion (MSC) - on 20 athletes' (Mage = 16.75 years) pain, cognitive appraisal, depression reinjury anxiety, psychological readiness to return to sport, and range of motion (ROM). IM and GS interventions have demonstrated initial effectiveness; however, no study has examined MSC in relation to post-ACL recovery. All athletes experienced significant decrease in pain (F(2) = 97.30, p = .000) from Week 1 to Week 7 and a significant increase in ROM from Week 2 to Week 7 (F(1) = 77.93, p = .000). All athletes experienced significantly higher depression at Week 1 compared to both Week 2 and Week 7 (F(2) = 9.01, p = .001), and significantly higher difficulty coping with their injury at Weeks 1 and 2 compared to Week 7 (F(2) = 6.32, p = .005). There were no statistically significant effects found between the intervention groups at Weeks 1, 2, and 7. However there were moderate effect sizes between interventions which suggest MSC and IM could help athletes cope with their injury during the first few weeks after surgery, and GS may …

It's Going to be Different, but It's Going to be Okay: Caregiver Perspectives on Autism, Culture and Accessing Care (open access)

It's Going to be Different, but It's Going to be Okay: Caregiver Perspectives on Autism, Culture and Accessing Care

Through ethnography influenced by public health and anthropological theory, I explored the cultural perceptions of autism among eight caregivers whose children received services from a local Dallas-Fort Worth autism treatment organization. Participant observations and semi-structured interviews with caregivers and program employees provided a rich and nuanced view into the state of care currently available in the DFW area while also highlighting areas for improvement. This research will be used to not only identify the barriers faced by North Texas Families while seeking out care,but also the strategies the organization uses when connecting with families from different backgrounds.

Location Estimation and Geo-Correlated Information Trends (open access)

Location Estimation and Geo-Correlated Information Trends

A tremendous amount of information is being shared every day on social media sites such as Facebook, Twitter or Google+. However, only a small portion of users provide their location information, which can be helpful in targeted advertising and many other services. Current methods in location estimation using social relationships consider social friendship as a simple binary relationship. However, social closeness between users and structure of friends have strong implications on geographic distances. In the first task, we introduce new measures to evaluate the social closeness between users and structure of friends. Then we propose models that use them for location estimation. Compared with the models which take the friend relation as a binary feature, social closeness can help identify which friend of a user is more important and friend structure can help to determine significance level of locations, thus improving the accuracy of the location estimation models. A confidence iteration method is further introduced to improve estimation accuracy and overcome the problem of scarce location information. We evaluate our methods on two different datasets, Twitter and Gowalla. The results show that our model can improve the estimation accuracy by 5% - 20% compared with state-of-the-art friend-based models. In the …

Ex-Offender Reentry: An Analysis of Current Policies and Programs (open access)

Ex-Offender Reentry: An Analysis of Current Policies and Programs

Recidivism rates among ex-offender populations have consistently remained high. With over 600,000 ex-offenders being released from prison each year, reducing the rate of recidivism among the ex-offender class has become a highly debated issue. Ensuring ex-offenders successfully reintegrate into the community post-incarceration may help to reduce recidivism rates. Through a qualitative thematic analysis, this study examined various policies and program that may impact recidivism rates among ex-offenders. The policies and programs reviewed in this study were categorized among six main themes which were identified in prior literature as the most crucial elements needed for successful reintegration. The findings indicate that while many policy changes have been made to positively impact ex-offender reintegration by allowing initial access to services post-release from prison, more should be done to ensure ex-offenders actually receive needed services.

School System Improvement through Building Leadership, Adult Learning, and Capacity: A Consideration of Instructional Rounds as a Systemic Improvement Practice (open access)

School System Improvement through Building Leadership, Adult Learning, and Capacity: A Consideration of Instructional Rounds as a Systemic Improvement Practice

The problem of the study was determining the supportive conditions related to instructional rounds (rounds) to understand better what conditions may allow for sustained systemic improvement over time. Three Texas school districts were studied to understand the perceptions of district leaders, principals, teacher leaders, and teachers with regard to the sustainability of instructional rounds as a systemic improvement practice, the supportive conditions necessary for sustainability, the salient characteristics that differentiated rounds from other improvement practices, and the potential of rounds to build organizational capacity. Observation of network rounds visits and document analysis was conducted to determine alignment of perception with observation and documents. Findings include perceptions, themes, and critical factors for the sustainability of rounds as an effective systemic improvement practice. Supportive conditions emerged as the most significant perception expressed by the participants. Implications for action for school districts beginning or continuing implementation of instructional rounds are suggested based upon findings from participant perceptions and observation of networks. Suggestions for future research are shared. With supportive conditions in place, instructional rounds has the potential to serve as an effective systemic improvement practice.

Practices that Influence Instructional Coaches' Perceptions of Effectiveness (open access)

Practices that Influence Instructional Coaches' Perceptions of Effectiveness

As instructional coaches are being implemented across the country, their purpose is reviewed, as well as which types of instructional coaching tend to have the most impact on teachers' instructional growth. In this study, I explored instructional coaching and coaches' perceived effectiveness as they work with teachers. A look at the effect of non-evaluative feedback with an instructional coach, and how that helps sustain teachers' pedagogical practice, is taken into consideration as coaches' work towards developing teacher efficacy. I examined instructional coaching through the conceptual framework of professional development and change. This qualitative study included a focus group, personal narratives, and individual interviews to analyze the components of successful instructional coaching models, and how well instructional coaches feel supported as they work with teachers. Findings demonstrated that instructional coaches perceive their work with teachers to be effective and provided information on the practices and conditions that surround their work. The information gained from the study provides a resource for district leaders to evaluate a current coaching model program, or implement a new coaching model program, within their district.

Non-Isothermal Laser Treatment of Fe-Si-B Metallic Glass (open access)

Non-Isothermal Laser Treatment of Fe-Si-B Metallic Glass

Metallic glasses possess attractive properties, such as high strength, good corrosion resistance, and superior soft magnetic performance. They also serve as precursors for synthesizing nanocrystalline materials. In addition, a new class of composites having crystalline phases embedded in amorphous matrix is evolving based on selective crystallization of metallic glasses. Therefore, crystallization of metallic glasses and its effects on properties has been a subject of interest. Previous investigations from our research group related to laser assisted crystallization of Fe-Si-B metallic glass (an excellent soft magnetic material by itself) showed a further improvement in soft magnetic performance. However, a fundamental understanding of crystallization and mechanical performance of laser treated metallic glass was essential from application point of view. In light of this, the current work employed an integrated experimental and computational approach to understand crystallization and its effects on tensile behavior of laser treated Fe-Si-B metallic glass. The time temperature cycles during laser treatments were predicted using a finite element thermal model. Structural changes in laser treated Fe-Si-B metallic glass including crystallization and phase evolution were investigated with the aid of X-ray diffraction, differential scanning calorimetry, resistivity measurements, and transmission electron microscopy. The mechanical behavior was evaluated by uniaxial tensile tests with …

Corbicula fluminea Invasion as a Secondary Effect of Hydrilla verticillata Management via Triploid Grass Carp (Ctenopharyngodon idella) (open access)

Corbicula fluminea Invasion as a Secondary Effect of Hydrilla verticillata Management via Triploid Grass Carp (Ctenopharyngodon idella)

A study of Asian clam (Corbicula fluminea Müller) colonization in relation to changes in aquatic vegetation community as a result of management of Hydrilla verticillata (L. f.) Royle with grass carp was conducted at the Lewisville Aquatic Ecosystem Research Facility (LAERF), Lewisville, TX, from April 2015 through October 2016. Percent vegetation cover, C. fluminea abundance and water quality metrics (pH, turbidity, conductivity, DO, calcium, chlorophyll a) from 16 experimental subjects were analyzed. Treatments included four replicated grass carp stocking densities; 1-control with no fish stocked (n = 4), 2-low density of 40-43 fish per vegetated ha (n = 4), 3-medium density of 72-81 fish per vegetated ha (n = 4) and 4-high density of 110-129 fish per vegetated ha (n = 4). Data analysis showed statistical significance in the relation of C. fluminea abundance to percent vegetation cover (multiple linear regression, r2 = 0.820), grass carp stocking densities (two-way analysis of variance, p = <0.001) and chlorophyll a (multiple linear regression, r2 = 0.339). Findings of this research indicate the possibility that management of hydrilla had enabled establishment of secondary invasive species.

Arduino Based Hybrid MPPT Controller for Wind and Solar (open access)

Arduino Based Hybrid MPPT Controller for Wind and Solar

Renewable power systems are becoming more affordable and provide better options than fossil-fuel generation, for not only the environment, but a benefit of a reduced cost of operation. Methods to optimize charging batteries from renewable technologies is an important subject for off-grid and micro-grids, and is becoming more relevant for larger installations. Overcharging or undercharging the battery can result in failure and reduction of battery life. The Arduino hybrid MPPT controller takes the advantage of solar and wind energy sources by controlling two systems simultaneously. The ability to manage two systems with one controller is better for an overall production of energy, cost, and manageability, at a minor expense of efficiency. The hybrid MPPT uses two synchronous buck DC-DC converters to control both wind and solar. The hybrid MPPT performed at a maximum of 93.6% efficiency, while the individual controller operated at a maximum 97.1% efficiency when working on the bench test. When designing the controller to manage power production from a larger generator, the inductor size was too large due to the frequency provided by the Arduino. A larger inductor means less allowable current to flow before the inductor becomes over saturated, reducing the efficiency of the controller. Utilizing …

The Effects of Multicultural Discussions and Supervisory Working Alliance on Multicultural Counseling Competence (open access)

The Effects of Multicultural Discussions and Supervisory Working Alliance on Multicultural Counseling Competence

This study examined the influence of multicultural training, multicultural discussions in supervision, and the supervisory working alliance on multicultural counseling competence. The sample consisted of 57 doctoral counseling interns, doctoral graduate students and post-doctoral students in counseling and clinical psychology. Participants completed several instruments including a demographic questionnaire, the Supervisory Working Alliance Inventory - Trainee, and the Multicultural Counseling Inventory. They filled out two questionnaires created for this study, one assessing multicultural discussions in supervision and another quantifying their multicultural training experience. Data analyses included multiple hierarchical regression, utilizing the Hayes PROCESS macro. Multicultural discussions in supervision moderated the relationship between the supervisory working alliance and multicultural counseling competence, but did not significantly moderate the relationship between multicultural training and multicultural counseling competence. Findings suggest that when multicultural discussions in supervision are positive, they significantly increases the strength of the relationship between good supervisory working alliance and multicultural counseling competence in psychology trainees. The findings may inform supervision practices and improve multicultural counseling competence in psychology graduate student trainees.

How Does It Feel to be Creative? A Phenomenological Investigation of the Creative Experience in Kinetic Places (open access)

How Does It Feel to be Creative? A Phenomenological Investigation of the Creative Experience in Kinetic Places

How does it feel to be creative? Such a question, when approached from a phenomenological perspective, reveals new understandings about the embodied experience of creativity, and how it feels as it is being lived. This investigation begins with a provocative contrast of two environments where creativity is thought to manifest itself: school art classrooms, where creativity is often legislated from an authority figure, and New Orleans Second Line parades, where creativity is organically and kinetically expressed. A thorough review of the literature on creativity focuses on education, arts education, creative economies, psychology, and critical theorists, collectively revealing a cognitive bias and striking lack of consideration for community, freedom, and the lived experience of being creative. Further discussions in the literature also neglect sites of creativity, and the impact that place (such as a school classroom) can have upon creativity. The phenomenological perspectives of Merleau-Ponty, Heidegger, Bachelard, and Trigg support a methodological lens to grasp embodied knowledge, perceptions of placedness on creativity, and the interdependent frictions between freedom, authenticity, movement and belonging. The research method includes investigations in New Orleans in archives, examination of visual and material culture, participation in cultural practice, and formal and informal interviews. Further, the phenomena of …

Supportive Systems for Building Capacity of the Elementary Instructional Coach (open access)

Supportive Systems for Building Capacity of the Elementary Instructional Coach

The purpose of this qualitative case study was to examine the systems in place to build the capacity of elementary instructional coaches in a fast-growth district. Through syntheses of research from educational scholars, the conceptual framework was developed with a focus on building capacity of instructional coaches in an ever-changing environment of fast-growth through the lens of professional learning communities, human and social capital, and support from district and campus administration. This study assessed the perceptions of six instructional coaches, six principals, and six district leaders from Rose ISD regarding the school district's support for building the capacity of instructional coaches within the elementary instructional coaching program. The three-part data collection process included document analysis, in-depth interviews, and focus group interviews to support triangulation of data. Through the a priori coding process, the following four themes emerged that highlight key components needed to support district leaders in establishing systems to build the capacity of instructional coaches in an ever-changing environment caused by fast growth: structured time for professional learning, program clarity, collaborative support systems, and implementation of a professional learning community framework. This study revealed a specific need to further understand systems for monitoring and evaluating the effectiveness of the …

When to Say It: Establishing a Verbal Cue (open access)

When to Say It: Establishing a Verbal Cue

Dog trainers sometimes teach verbal cues by saying the cue as the dog is performing the desired behavior. However, there is disagreement about when to say the cue. In this study, a pet dog was trained to go to three different apparatus, the cue for each of which was given at a different time, in a multi-element design. The cue "hoop" was given just as the dog began to move to the hoop apparatus. The cue "carrier" was given as the dog was stepping into the carrier apparatus. The cue "platform" was given after the dog was sitting on the platform apparatus. To test if the dog had learned the cues, the trainer had the dog sit and gave the cue. During testing, if only the correct apparatus was present, the dog responded to all three cues. However, when all three apparatus were present, the dog only responded correctly to the "hoop" cue. This suggests that giving the cue just as the learner is beginning to perform the desired behavior is the most effective teaching method.

Musical Priming and Operant Selection (open access)

Musical Priming and Operant Selection

Language is a cultural construct, and the relationship between words is taught. Priming research has long investigated the relationship between related and unrelated words. Similar research has been seen in music relationships, but most of these investigate harmonic relations despite the melodic relationship being the one listeners are mostly likely to describe. Further, these studies typically measure existing relationships and do not attempt to teach a new relationship, nothing that most adults are experienced musical listeners. This study seeks to establish a new melodic relationship (the enigmatic Scale) in addition to a familiar one (the major Scale) while measuring response time to the musical sequences. A baseline was conducted in which participants listened to a musical sequence and selected via response box if the final note is consonant (major Scale) or dissonant (enigmatic Scale). Following baseline a training section occurred in which participants heard sequences ranging from 2-7 notes and were provided feedback for correct and incorrect responses. Following completion of the training participants completed a post-test identical to baseline. Behavioral results are discussed in relation to Palmer's (2009) concept of the repertoire.

Historical Memory and Ethics in Spanish Narrative (open access)

Historical Memory and Ethics in Spanish Narrative

This study traces the current status of Spanish ethics as seen through the optics of historical memory. Starting from the Spanish Civil War in 1936, the thesis relates contemporary themes to their proposed origin throughout three additional distinctive eras of the 20th and 21st century in Spain: 1982-1996 (Socialist Spain), 1997-2010 (Post-modern Spain), and 2011-present (current Spain). Spanish narratives ranging from Los Abel by Matute, La magnitud de la tragedia by Monzó, "Fidelidad" of Ha dejado de llover by Barba and Las fosas de Franco by Silva are contextualized through their ethical architecture, in accordance with their socio-political context, and relationship to past historical traumas. This work proposes that the themes of anticlericalism, the pursuit of social equality, anti bureaucracy, and political distrust are trends culminating from Kohlberg's third level of morality. The thesis aims to be an exposition and legitimization of different ethical schemas that might otherwise be polarized as wrong and inferior by others.

Shear and Bending Strength of Cold-Formed Steel Solid Wall Panels Using Corrugated Steel Sheets for Mobile Shelters (open access)

Shear and Bending Strength of Cold-Formed Steel Solid Wall Panels Using Corrugated Steel Sheets for Mobile Shelters

The objective of this thesis is to determine if the single sided resistance spot weld (RSW) can be used as a feasible connection method for cold formed steel (CFS) shear walls subject to lateral force of either seismic or wind loads on mobile shelters. The research consisted of three phases which include: a design as a 3D BIM model, connection tests of the resistance spot weld, and full-scale testing of the designed solid wall panels. The shear wall testing was conducted on specimens with both resistance spot weld and self-drilling screws and the results from tests gave a direct comparison of these connections when the solid wall panel was subjected to in-plane shear forces. The full-scale tests also included 4-point bending tests which was designed to investigate the wall panel's resistance to the lateral loads applied perpendicularly to the surface. The research discovered that the singled sided resistance spot weld achieved similar performance as the self-drilling screws in the applications of CFS wall panels for mobile shelters. The proposed single sided resistance spot weld has advantages of low cost, no added weight, fast fabrication, and it is a feasible connection method for CFS wall panels.
