This validation study examined the Triple E Rubric for Lesson Design as a measurement tool to test the effectiveness of a lesson when using technology to support learning goals. This study also measured the content and concurrent validity as well as reliability of the Triple E Rubric developed by Liz Kolb.

This study explores where African American college students find mental health support and why those supports are chosen. Greater knowledge of the sources of mental health support sought by African American college students can assist higher education institutions in adapting current services to meet the needs of this specific student population. A qualitative phenomenological approach was utilized, and the study's sample included twelve participants, 6 female and 6 male, from a large public four-year university in Texas. These participants, undergraduate students with ages ranging from 18 to 24, were given a survey and completed two semi-structured interviews throughout one semester. Results indicated that study participants were more likely to utilize informal than formal support for their mental health and many had no source of support. Family stigma, peer attitudes, as well as internal and external pressures all influenced participant's choices to seek support. Based on findings from the study, recommendations for two distinct groups, counseling center directors and higher education administrators, are also discussed.

There is a growing expectation that school librarians function within their job descriptions beyond the role of reading promoter and resource manager. With college and career readiness standards, technology use and digital learning standards and information literacy standards now in place for student learning expectations, it is vital that students have opportunities to acquire, develop and practice such skills for future success in the global market economy. For students to receive such opportunities, there should be designed instruction delivered to students that allows for them to learn and practice information gathering techniques to access, use and apply information effectively, efficiently and ethically while developing technology skills within context of their content learning and real-world connections authentically. This study examined how school librarians conveyed information gathering techniques to students through a qualitative, constant comparative approach. Five middle school librarians in an urban school district participated in an observation and interview. Findings suggest that school librarians do claim an instructional role regarding information gathering and technology usage, although it manifests in diverse ways. Implications for future studies and practice suggest that the position become more defined such that the expectation to function in these roles is widely accepted by all stakeholders, and …

This qualitative case study explored how school district and campus-level administrators coordinate resources and services for currently enrolled homeless students. Participants in this study included three district-level administrators designated as the homeless liaison and three campus principals. Data collected and analyzed included audio recordings of semi-structured interviews of each participant, documents at the district and campus-levels, school board meeting notes, and research field notes. The findings suggested that district and campus stakeholders embraced a shared vision of collaborative policy implementation to support the needs of students living in homelessness conditions. Findings also suggested that moral purpose is reflected through the intentional, collaborative efforts of district and campus administrators. Additionally, the findings suggested that social capital develops in the collaborative processes between district and campus leaders while they broker resources to foster developing social capital of this student population. Mobilization of resources through collaborative policy implementation can foster cohesion while supporting students and can counter the impact of living in homelessness conditions.

Previous studies highlighted the importance of parental support for development of mastery of control and depressive symptoms. These studies tended to examine one time wave and outcomes related to that period, forwarding an assumption parenting behaviours do not change as children age. Using the National Longitudinal Survey of Youth 1979-Children and Young Adults, this study filled the gap by examining children's supportive environment at three time points and determining how levels of support across these points impacted children's depression and mastery at 18 years of age. Relative stability of mothers' supportive parenting (i.e., encouragement of social maturity, warmth and affection, and physical punishment) at early childhood, middle childhood, and early adolescence was examined by Kendall's tau correlations. Encouragement of social maturity showed relative stability between early and middle childhood and middle childhood and early adolescence; warmth and affection showed relative stability between early and middle childhood, and physical punishment showed relative stability across all time points. Absolute stability was examined using hierarchical linear modelling and Wilcoxon signed-rank test. No instances were found. Latent class growth analysis identified different trajectories of supportive environment among participants and three groups were identified. Multiple regressions conducted to examine how different trajectories affect late adolescents' …

Indicators of quality early intensive behavioral intervention (EIBI) include comprehensive interventions, adequately trained staff, high rates of effective instruction delivery, happy interactions between children and their teachers, and socially valid outcomes. When these are in place, high quality EIBI is more likely to increase progress that children with autism make during treatment. When not in place, progress is not as likely, as rapid, or as meaningful. To date, there is limited research regarding the correlation between these indicators of high-quality EIBI and the degree to which their effects are meaningful to direct consumers. The purpose of this methodological study was to compare direct, quantitative measures of teaching interactions (child initiations, teacher initiations, child affect, teacher affect) with qualitative measures (stakeholder ratings of teacher effectiveness, amount of opportunities for interaction and interest in the child) of teaching interactions to determine what sets the occasion for expert stakeholders to describe a teaching interaction as effective, quality therapy.

A primary task of adolescence and young adulthood is to form and develop healthy romantic relationships. While the importance of sibling and romantic relationships have been examined separately, only recently have researchers begun to explore links between the two. The purpose of the present study was to investigate the connection between romantic competence and sibling relationships, especially sibling warmth and sibling conflict, as well as the role of sibling gender constellation in college-aged young adults. This study aimed to examine (a) whether there is an association between sibling relationship quality, such as sibling warmth and sibling conflict, and perceived romantic competence, and (b) the role of sibling gender constellation on the relationship between sibling relationship quality (sibling warmth and sibling conflict) and perceived romantic competence among undergraduate students. Correlation analyses indicated there was no statistically significant correlation between sibling warmth and perceived romantic competence (p > .05), whereas sibling conflict was statistically negative correlated with perceived romantic competence (p < .01). While sibling gender constellation did not have an interaction effect with sibling conflict on perceived romantic competence, which means sibling gender constellation did not have a moderating effect on the relationship between sibling conflict and perceived romantic competence. Limitations …

Modern cities are undergoing rapid expansion. The number of connected devices in the networks in and around these cities is increasing every day and will exponentially increase in the next few years. At home, the number of connected devices is also increasing with the introduction of home automation appliances and applications. Many of these appliances are becoming smart devices which can track our daily routines. It is imperative that all these devices should be secure. When cryptographic keys used for encryption and decryption are stored on memory present on these devices, they can be retrieved by attackers or adversaries to gain control of the system. For this purpose, Physical Unclonable Functions (PUFs) were proposed to generate the keys required for encryption and decryption of the data or the communication channel, as required by the application. PUF modules take advantage of the manufacturing variations that are introduced in the Integrated Circuits (ICs) during the fabrication process. These are used to generate the cryptographic keys which reduces the use of a separate memory module to store the encryption and decryption keys. A PUF module can also be recon gurable such that the number of input output pairs or Challenge Response Pairs (CRPs) …

Charles Stewart Parnell was James Joyce's most significant political influence to a degree that has yet to be fully acknowledged or explored. This thesis proposes a "theory of Parnell" in Joyce's works up to the end of Ulysses, arguing that close attention to Parnell's evolution points to a significant shift in the evolution of Joyce's literary forms. In Joyce's juvenilia, political writings, and early fiction, Parnell always appears with a heroic, even Messianic, cast, which the most significant moments in the fiction pair with a strict adherence to dramatic forms. However, significant moments in both "Ivy Day in the Committee Room" and A Portrait of the Artist as a Young Man lay the groundwork for stylistic and representative transformations in Ulysses. In that novel, the myth of Parnell is deflated, even as Joyce appropriates its most essential qualities in the development of his panoply of styles. Episodes from "Telemachus" to "Wandering Rocks" critically examine the myth of Parnell even as they link it with the constraints of dramatic forms. Later episodes, most notably "Cyclops," "Circe," and "Eumaeus" attempt to make use of elements of "Parnellite" style, training a community of readers in acts of collective imagination that keep the Parnellite …

Although trans* students often face greater levels of discrimination, harassment, and hostility on college campuses than their cisgender peers, research indicated that they can succeed by developing and honing survival strategies, such as resilience and being part of a trans* kinship network that resists trans* oppression. Having the support of family, and by taking the risk to cultivate relationships while in college also improves the likelihood of persistence through college. The term trans* is used in this study as an inclusionary term for transgender persons and other gender nonbinary identities. The purpose of this research study was to explore the experiences that trans* students have while being in college. Utilizing a phenomenological approach and the theoretical lens of feminist and queer theories, semi-structured interviews were conducted to better understand the lived experiences of trans* college students. Four Caucasian trans* undergraduate students, ranging in age from 19 to 25 were each interviewed five times. Twenty total interviews over a period of three months provided in-depth data. Five primary themes emerged that were common among the participants: exploration, experimentation, and self-discovery; living as a trans* person in college: developing survival strategies; cultivating relationships and seeking acceptance; race and gender privilege/power; and generational …

During the New Deal, the Civilian Conservation Corps (CCC) put young men to work in state and national parks across the United States. One of such parks, Big Bend National Park, is the focus of this study. The CCC had two camps within the park, one from 1934 to 1937 and another from 1940 to 1942. During their time in Big Bend, the CCC constructed many projects including a road, trails, cabins, and other various structures. The purpose of this study is to delineate the role of the CCC in creating Big Bend National Park and the experience of the CCC during their time in the Big Bend camp. This study determines the role of the CCC through a discussion of the planning done by the CCC for Big Bend National Park and the work completed by the CCC in the park. In doing so, it argues that the CCC played a substantial and significant role in the development and character of the park. This study works to understand the experience of the CCC in Big Bend through a discussion of education, safety, and an investigation of a commanding officer. Through this discussion, the role of the federal government and …

Since phages use the host resources to replicate themselves after infection, the different sizes of the phage genome should influence the replication rate. We, therefore, hypothesized that the smaller genomes should burst the cell faster than the larger ones. As well, the shorter genomes would have greater burst sizes because they should replicate faster. Here, we obtained 16 phages of various genome length. All phages were isolated on Streptomyces griseus and available in our phage bank at the University of North Texas. We performed one-step growth studies for the 16 phages, as well as determined the host doubling time from its growth curve. The results show that S. griseus grown in nutrient broth has a doubling time of 5 hours and 22 minutes. This doubling time is used as a guideline for the phage growth studies. Because the filamentous nature of the host caused several difficulties during the experiment, we isolated single cells by sonication and centrifugation. After the cell number was determined by viable cell count, the cells were infected with each type of phage using a multiplicity of infection (MOI) of 0.5. The results show that phages' burst times range between 45 (±0, standard error) and 420 (±30) …

In this dissertation, we present a number of studies that primarily focus on data movement challenges among different types of memories (viz., 3D-DRAM, DDRx DRAM and NVM) employed together as a flat-address heterogeneous memory system. We introduce two different hardware-based techniques for prefetching data from slow off-chip phase change memory (PCM) to fast on-chip memories. The prefetching techniques efficiently fetch data from PCM and place that data into processor-resident or 3D-DRAM-resident buffers without putting high demand on bandwidth and provide significant performance improvements. Next, we explore different page migration techniques for flat-address memory systems which differ in when to migrate pages (i.e., periodically or instantaneously) and how to manage the migrations (i.e., OS-based or hardware-based approach). In the first page migration study, we present several epoch-based page migration policies for different organizations of flat-address memories consisting of two (2-level) and three (3-level) types of memory modules. These policies have resulted in significant energy savings. In the next page migration study, we devise an efficient "on-the-fly'" page migration technique which migrates a page from slow PCM to fast 3D-DRAM whenever it receives a certain number of memory accesses without waiting for any specific time interval. Furthermore, we present a light-weight hardware-assisted …

Styrene production by a (FlDAB)PdII(TFA)(η2-C2H4) complex was modeled using density functional theory (DFT). Benzene C-H activation by this complex was studied via five mechanisms: oxidative addition/reductive elimination, sigma-bond metathesis, concerted metalation deprotonation (CMD), CMD activation of ethylene, and benzene substitution of ethylene followed by CMD of the ligated benzene. Calculations provided evidence that conversion of benzene and ethylene to styrene was initiated by the fifth pathway, arylation via CMD of coordinated benzene, followed by ethylene insertion into the Ru-Ph bond, and then β-hydrogen elimination. Also, monomer (active species)/dimer equilibrium concentrations were analyzed. The results obtained from present study were compared with that of a recently reported RhI complex to help identify more suitable catalysts for the direct production of styrene from ethylene and benzene. Second, theoretical studies of heterobimetallic {Ag–Fe(CO)5}+ fragments were performed in conjunction with experiments. The computational models suggested that for this first example of a heterodinuclear, metal-only FeAg Lewis pair (MOLP) that Fe(CO)5 acts as a Lewis base and AgI as a Lewis acid. The ῡCO bands of the studied molecules showed a blue shift relative to those measured for free Fe(CO)5, which indicated a reduction in Fe→CO backbonding upon coordination to silver(I). Electrostatic interaction is predicted …

The Dallas Morning News is a leader in using engagement journalism to increase and retain digital subscribers. This ethnography examined the efficacy of the engagement journalism work by the News in rebuilding trust and forming relationships with its audience. This research is exceptionally timely as more newsrooms are erecting paywalls to their content and asking their audiences to offer monetary support in exchange for greater access and engagement by journalists. This work is examined through two mass communications theories: functionalism, which says a society can be viewed like an ecosystem as a "system in balance" consisting of complex sets of interrelated activities, each of which supports the others in maintaining the system as a whole; and the dual responsibility model, which says that companies should operate in the best interests of all in the community who depend on them, not only those who benefit financially. Additionally, the work is considered from a human-interaction design standpoint to evaluate whether the News has created affordances that enable the journalists and the readers to communicate, and whether the journalists are effectively practicing service design when publishing news and information for the audience.

While a growing body of literature in the field of criminal justice documents the relationship between victimization and offending, only recently has this knowledge been applied to the study of intimate partner violence (IPV). Accordingly, questions remain with regard to the theoretical origins of mutual violence between intimates. In an effort to fill this void in the literature, the current study examines the etiology of moderate forms of mutual IPV, specifically assessing self-control theory's applicability to the victim-offender overlap in IPV. Data were obtained from Waves I and IV of the National Longitudinal Study of Adolescent to Adult Health (Add Health) to investigate whether low self-control at Wave I predicts IPV victimization, IPV offending, or both IPV victimization and offending at Wave IV. The present study extends prior literature examining the role of self-control in IPV by (1) investigating the influence of self-control on the victim-offender overlap in IPV, (2) using longitudinal data, and (3) utilizing a sample of U.S. adults ages 24 to 33. While low self-control was found to significantly predict IPV offending and the overlap in IPV victimization and offending, low self-control failed to significantly predict IPV victimization. Policy implications, study limitations, and directions for future research …

C-lignin (caffeyl-lignin) is a novel linear lignin polymer found in the seed coats of several non-crop plants, notably Vanilla planifolia (Vanilla), Jatropha Curcas (Jatropha), and Cleome hassleriana (Cleome). C-lignin has several advantages over normal G/S-lignin, found in the majority of lignocellulosic biomass, for valorization in the context of bioprocessing: less cross-linking to cell wall polysaccharides (less recalcitrant biomass), ordered linkages between monomers (homogeneous polymer), and no branching points (linear polymer). These properties make C-lignin an attractive replacement for native lignin in lignocellulosic biomass crops. The seed coats of Cleome hassleriana (Cleome) synthesize G-lignin during early seed maturation, then switch to synthesis of C-lignin during late maturation. This switch to C-lignin in Cleome seed coats is accompanied by loss of caffeoyl-CoA 3-O-methyltransferase (CCoAOMT) and caffeic acid 3-O-methyltransferase (COMT) activities, along with changes in transcript abundance of several lignin related genes. The focus of this research thesis is to understand the biochemical changes leading to C-lignin deposition in Cleome hassleriana seed coats, and to explore the ability of Arabidopsis thaliana seedlings to polymerize caffeyl alcohol to C-lignin. In this thesis, candidate transcripts were implicated in C-lignin biosynthesis by differential gene expression analysis of transcripts in seed coat tissues at 8-18 days after …

The role of the principal has become increasingly complex and challenging. Recent emphasis has been placed on the role of principals as leaders who can build a culture of learning in schools to close the student achievement gap. Outside factors such as fast-growth in Texas have caused schools to change and grow quickly, which increases the learning demands placed on principals as they seek to develop the knowledge and skills needed for effective leadership. Developing and sustaining a professional learning community is a powerful strategy that has been found to improve teaching and learning, however developing professional learning communities requires skilled leadership. Limited research exists regarding how principals learn to implement and sustain professional learning communities within fast-growth districts, therefore, with this phenomenological qualitative research, I explored the lived experiences of seven principals within one fast-growth district in Texas to explore how they learned to develop and sustain a professional learning community.

In rural, low socioeconomic public schools, the diversity of the student population challenges teachers beyond their means to meet the wide-ranging needs of students, and therefore creating opportunity gaps. The purpose of this study was to explore one district's leadership support of teachers to create an equitable learning environment for all students. The present study built on existing literature by discovering leadership practices and perceived necessary supports for closing achievement gaps in K-12 classrooms. Through interviews with district and school administrators, classroom teachers, and observations of leadership meetings, the research for this case study included data collection and analysis. From the interview questions and observations, six themes emerged. The themes revealed from the data collected and analysis for this qualitative study aligned with the components of the conceptual framework, a sequence of initiative requirements for equitable learning environments. Developing a sequence of initiatives among all levels of educators could benefit sustainment of an equitable learning environment in Rural ISD. Recommended for further research is professional development to both leadership and teachers about professional learning communities (PLCs). In addition, study of parent education programs and how relationships achieve more parental involvement requires further research. A final recommendation for collegiate education preparation …

Improving water efficiency is and will continue to be a top concern to meet the world food production demands for a growing population. By having a clear understanding of water efficiencies, communities will be able to address these concerns from an economic standpoint and use more productive methods to grow food and limit water consumption. This study examines the water efficiencies of three irrigation methods over a single growing season in southeastern Oklahoma. Two crops, tomatoes and cucumbers, were grown using drip irrigation, a self-wicking container, and a non-circulating hydroponics barrel. Results at the end of the season showed the drip irrigation method had the highest water efficiency in terms of yield of product over water applied for both crops. The drip irrigation method also had the lowest associated set up costs and second lowest time requirements after the hydroponics method. These results were found to be consistent with other studies that compared drip irrigation to other irrigation methods and showed drip to have the highest water efficiencies.

Older gay men and lesbians may be at greater risk for depression than older sexual majority adults due to a lifetime of sexual minority stress. We hypothesize that aggression and being single are positively associated with depression. Resilience is negatively associated with depression. Aggression, being single and resilience account for a significant proportion of variance in depression. Resilience moderates the relationship between aggression and depression. Significant differences between older gay men and older lesbians' aggression, resilience and depression scores exist. For our older gay men and lesbian combined group, a moderation analysis indicated that in addition to aggression and resilience, being single significantly predicted depression accounting for approximately 57% of the variance in depression. Furthermore, resilience significantly moderated the relationship between aggression and depression in our model of older gay men and lesbians. For our older gay men-only group a moderation analysis (indicated that and resilience significantly predicted depression accounting for approximately 57% of the variance in depression. Furthermore, resilience significantly moderated the relationship between aggression and depression in our model, in our sample of older gay men. Four our lesbian-only group a moderation analysis indicated that being single and resilience significantly predicted depression accounting for approximately 54% of the …

Pierre-Philippe Bauzin (1933-2005) was a skilled keyboard performer, improviser, and composer. By way of his close personal friendship with renowned saxophonist Jean-Marie Londeix, Bauzin began dedicating, composing, and often times performing music for saxophone with Londeix, beginning in 1959. The results of this friendship produced eleven original works for saxophone with diverse instrumentation, ranging from solo compositions to large ensembles. Due to Bauzin's preference for improvising the piano accompaniments of his music on each performance, however, a majority of his compositions were thought to be incomplete or lost. This study surveys Bauzin's complete opus for saxophone by way of both his published works, and the author's rediscovery of the manuscripts to these previously assumed lost compositions for saxophone. The pieces studied are Sonata no. 1 (1959), Poème (1960), Cinq Pièces Breves en Forme de Musique (1960), Esquisses (1967), Divertimento (1968), and Quatuor no. 1 (1962). In addition, chapter 8 provides information regarding other compositions for saxophone by Bauzin that did not survive in their completed form. The survey of each work contains information pertaining to creation, performances of significance in saxophone history, and compositional techniques present within each work that can be used to identify the components of Bauzin's unique …

The rasa theory of Indian aesthetics is concerned with the nature of the genesis of emotions and their corresponding experiences, as well as the condition of being in and experiencing the aesthetic world. According to the Indian aesthetic theory, rasa ("juice" or "essence," something that is savored, that is tasted) is an embodied aesthetic experienced through an artistic performance. In this thesis, I have investigated how the aesthetics of rasa philosophy account for creative presence and its experiences in Karnatik vocal performances. Beyond the facets of grammar, Karnatik rāga performance signifies a deeper ontological meaning as a way to experience rasa, idiomatically termed as rāga-rasa by South Indian rāga practitioners. A vocal performance of a rāga ideally depends on a singer's embodied experience of rāga and rāga-bhāva (emotive expression of rāga), as much as it does on his/her theoretical knowledge and skillset of a rāga's svaras (scale degrees), gamakas (ornamentation), lakṣhaṇās (emblematic phrases), and so on. Reflecting on my own experience of being a Karnatik student and performer for the last two decades, participant observation, interviews, and analysis of Indian aesthetic theory of rasa, I propose a way of understanding that to sing rāga is to embody bhāva opening the …

Alberto Nepomuceno (1864-1920) is considered to be the father of the Brazilian art song. With a total of seventy songs, Nepomuceno revolutionized and established a new path to the Brazilian art song. His songs were innovative because they: (1) incorporated folk elements in his songs, (2) introduced Portuguese as a language acceptable in bel canto style and (3) established Brazilian songs in the tradition of the European vanguard. His approach influenced several composers including his young student Heitor Villa-Lobos (1887-1959), one of the most significant Latin American composers. The purpose of this research is to inform singers and teachers about one of Brazil's most significant art song composers, and to provide the necessary tools--Brazilian Portuguese diction guide, IPA and poem translations of the selected songs--for effective and accurate performances and interpretations.
