SEM Predicting Success of Student Global Software Development Teams

SEM Predicting Success of Student Global Software Development Teams

Date: May 2015
Creator: Brooks, Ian Robert
Description: The extensive use of global teams to develop software has prompted researchers to investigate various factors that can enhance a team’s performance. While a significant body of research exists on global software teams, previous research has not fully explored the interrelationships and collective impact of various factors on team performance. This study explored a model that added the characteristics of a team’s culture, ability, communication frequencies, response rates, and linguistic categories to a central framework of team performance. Data was collected from two student software development projects that occurred between teams located in the United States, Panama, and Turkey. The data was obtained through online surveys and recorded postings of team activities that occurred throughout the global software development projects. Partial least squares path modeling (PLS-PM) was chosen as the analytic technique to test the model and identify the most influential factors. Individual factors associated with response rates and linguistic characteristics proved to significantly affect a team’s activity related to grade on the project, group cohesion, and the number of messages received and sent. Moreover, an examination of possible latent homogeneous segments in the model supported the existence of differences among groups based on leadership style. Teams with assigned leaders ...

A Comparative Analysis of State Funds on Student Achievement of Economically Disadvantaged Elementary Schools in Independent School Districts and Charter Schools in the State of Texas

A Comparative Analysis of State Funds on Student Achievement of Economically Disadvantaged Elementary Schools in Independent School Districts and Charter Schools in the State of Texas

Date: May 2015
Creator: Applewhite, Gary
Description: The purpose of this study was to evaluate the relationship between the instructional outcomes in the independent school districts and charter schools in relation to the expenditure of public funds for instruction and total operating expenditures from the general fund. The study considered Texas elementary charter schools and independent school districts, whose school populations were identified as having greater than or equal to 50% of economically disadvantaged students, according to the Texas Academic Excellence Indicator System (AEIS). The study made use of multiple regression and was an ex post facto cross-sectional analysis utilizing production function theory. The study’s outcomes reported the difference in student achievement between elementary schools in independent public school districts and charter schools were small to negligible for math and reading achievement. The study also reported, there is no statistically significant difference in per pupil expenditure of public funds between elementary schools in independent public school districts and charter schools. Furthermore, there is no statistically significant relationship between student achievement and per pupil expenditure of public funds on elementary schools in independent public school districts and charter schools.

Factorial Validity and Measurement Envariance of the Test of Performance Strategies, Sport Anxiety Scale, and the Golf Performance Survey Across Age Groups

Factorial Validity and Measurement Envariance of the Test of Performance Strategies, Sport Anxiety Scale, and the Golf Performance Survey Across Age Groups

Date: August 2014
Creator: Deiters, Jay A.
Description: The purpose of this study was to examine the factorial validity and measurement equivalence of the Test of Performance Strategies (TOPS; Thomas, Murphy, & Hardy, 1999); the Sport Anxiety Scale (SAS; Smith, Smoll, & Schultz, 1990); and the Golf Performance Survey (GPS; Thomas & Over, 1994) across age groups in a representative sample of amateur golfers. Based on archival data, participants comprising this study were 649 younger adult (n = 237) and older adult (n = 412) amateur golfers who played in the Dupont World Amateur Golf Championship in Myrtle Beach, South Carolina. The participants completed a set of questionnaires including psychological skills and strategies (e.g., self-talk, goal setting, imagery, etc.) used during competition, sport-specific competitive trait anxiety, and psychomotor skills and involvement in golf. Results demonstrated that the original factor structure of the TOPS competition subscale, the SAS, and the GPS, did not adequately fit the data among this sample of younger and older adult amateur golfers. Further exploratory and confirmatory factor analyses established evidence of factorial validity with the TOPS competition subscale, SAS, and the GPS with both younger and older adult amateur golfers. Configural, metric, scalar, and strict measurement invariance were identified in relation to the TOPS ...

Levanten La Mano Si Me Entienden: Receptive Bilinguals’ Linguistic and Cultural Perceptions in Secondary Spanish Classes

Levanten La Mano Si Me Entienden: Receptive Bilinguals’ Linguistic and Cultural Perceptions in Secondary Spanish Classes

Date: May 2015
Creator: Baker, Adelita Gonzales
Description: Receptive bilinguals have been in a dilemma of knowing just enough Spanish to write and aurally comprehend the curriculum at the beginning-intermediate levels of a Spanish language course. This dichotomy in classrooms with mixed-ability learners has created a need to reconsider placement and pedagogical structures tailored for these students in foreign language courses. Thus, this descriptive study examined the perceptions of receptive bilinguals, drawn from two secondary Spanish courses regarding receptive bilinguals’ language use, personal Spanish language abilities and confidence, personal beliefs about the language, and contentment with the course. For this study, 31 participants were selected from two public high schools in a suburb of a large metropolitan area in north Texas. Two surveys, a listening assessment and an online questionnaire, were administered at the end of the academic year. The Likert questionnaire items were analyzed using SPSS software, while open-ended questions were coded for recurrent themes. Analyses revealed four major findings. First, with regard to influence on language use, participants’ grandparents created the most interaction with the Spanish language when compared with the other family groups. In addition, Spanish influence through television, literature, radio, and music contributed to students’ early childhood Spanish learning. Second, as to language preference, ...

First Movement of the Beethoven Third Piano Concerto: An Argument for the Alkan Cadenza

First Movement of the Beethoven Third Piano Concerto: An Argument for the Alkan Cadenza

Date: May 2015
Creator: Ding, Yang
Description: The goal of this dissertation is not only to introduce the unique cadenza by Alkan but also to offer an argument from the performer’s point of view, for why Alkan’s cadenza should be considered when there exists a cadenza by Beethoven himself, not to mention those by a number of other composers, both contemporaries of Beethoven and later. Information in reference to the brief history of the cadenza and the pianoforte in the time of Mozart and Beethoven is presented in Chapter 2. A brief bibliography about Alkan is presented in Chapter 3. Chapter 4 describes not only the cadenza in the era of Alkan, but also a comparison which is presented between Beethoven and Alkan's cadenzas. Examples of the keyboard range, dynamic contrast, use of pedal and alternating notes or octaves, and creative quote are presented in Chapter 4. In conclusion, the revival of Alkan's cadenza is mentioned, and the author's hope to promote the Alkan's cadenza is presented in Chapter 5.

Information Seeking Behaviors in a Population of Assistive Mobility Device Users

Information Seeking Behaviors in a Population of Assistive Mobility Device Users

Date: May 2014
Creator: White, Mel
Description: The author explores the current state of information exchange and access in the procurement process for mobility assistive equipment. While the idealized model is of a linear process starting with a need and ending with the purchase, in practice the procedures for acquiring a device such as a wheelchair or electric scooter can be a time consuming task that involves client, family, medical care specialists, vendors, manufacturers, insurance companies and possibly alternate sources of funding. This study utilized Participatory Action Research (PAR) to collect both qualitative and quantitative data about information sources such as the Internet, the medical community, and vendors. The findings of this study suggest that in spite of the presence of the Internet, overall primary sources are similar to the traditional model and that for most there is no one source that could be easily accessed for information. A brief examination is made of the “Information landscape” utilized in the process and a brief discussion of two relatively unmentioned information sources: expos and the wheelchair sports community.

Refining the Definition and Detection of Response Styles: An Initial Examination of Defensiveness and Feigning on the Personality Inventory for DSM-5

Refining the Definition and Detection of Response Styles: An Initial Examination of Defensiveness and Feigning on the Personality Inventory for DSM-5

Date: May 2015
Creator: Fiduccia, Chelsea E.
Description: The fifth edition of the Diagnostic and Statistical Manual for Mental Disorders (DSM 5) presents an alternate model for personality disorders, blending categorical and dimensional assessment into a hybrid diagnostic procedure. Released concurrently, the Personality Inventory for DSM 5 (PID 5) measures the five domains and 25 facets that comprise the trait components of this hybrid model. However, the PID 5 currently lacks validity indicators to capture intentionally distorted responding. The current study investigated the susceptibility of the PID 5 to defensiveness and feigning among a large sample of undergraduate students. First, a detailed desirability analysis (N = 465) was conducted of the PID 5 items and response options. Responses from the study were used to create three desirability based validity scales. Next, in a between-subjects simulation design (N = 128), the effects of faking were explored at domain and facet levels. As a result, two symptom based validity scales were created. In a separate validation sample (N = 134), the five newly created validity scales were compared with the Paulhus Deception Scales for capturing both defensiveness and feigning. All five scales were evaluated for ruling out faking (i.e., identifying likely genuine respondents) and ruling in either defensiveness or feigning. ...

Enacting Community Through the Arts

Date: December 2014
Creator: Keller, Sarita Talusani
Description: This study is concerned with the roles and relationships between artists-in-residence, community audiences, and program coordinators/art educators as they engage together in community arts programs. This study takes place at Project Row Houses (PRH), a community arts organization located in Houston, Texas and focuses on the artist-in-residence program, which commissions a group of national and international artists for a 6-month period to create art installations in relation to the community and its African-American heritage. This ethnographic case study is based on the activities and events surrounding the 2008 PRH exhibition, Round 29, Thunderbolt Special: The Great Electric Show and Dance, after Sam Lightnin’ Hopkins and employed qualitative data gathering methods of participant-observation, conducting semi-structured, open-ended, in-depth interviews, and through document collection, and contextual information. Observations were recorded through field notes, photographs, and video. Interviews were conducted with 3 artists-in-residence, 3 community audience members, and 3 program coordinators or staff members involved with the program, regarding their experiences at the site and experiences with each other. My analysis presents the roles of artist, community audience, and program coordinator/art educator through three sections on cultural work. Within these sections I discuss topics related to the power of voice, situatedness, and creativity, as ...

Improving Processing Efficiency for Forensic DNA Samples

Improving Processing Efficiency for Forensic DNA Samples

Date: May 2015
Creator: Connon, Catherine Cupples
Description: The goal of this project was to reduce processing time for forensic DNA testing without incurring significant added costs and/or the need for new instrumentation, while still generating high quality profiles. This was accomplished by: 1) extraction normalization using the ChargeSwitch® Forensic DNA Purification Kit such that a small range of DNA concentrations was consistently obtained, eliminating the need for sample quantification and dilution; 2) developing fast PCR protocols for STR primer sets using shorter amplification methods, low volume reactions and non-fast thermal cyclers; and 3) developing a quicker 3130xl Genetic Analyzer detection method using an alternative polymer/array length combination. Extraction normalization was achieved through a reduction in bead quantity, thereby forcing an increase in bead binding efficiency. Four products (AmpliTaq Gold® Fast PCR Master Mix, KAPA2G™ Fast Multiplex PCR Kit, SpeedSTAR™ HS DNA Polymerase and Type-it Microsatellite PCR Kit) were evaluated for low volume (3μl) fast PCR on a 384-well Veriti® thermal cycler with the Identifiler primer set. KAPA2G™ was selected for 3μl fast PCR protocols using PowerPlex 16 HS and Identifiler Plus primer sets (42-51min), as well as 5μl and 6μl Identifiler fast reactions on a 9700 thermal cycler (51-60min). Alternative detection (POP-6™/22cm) achieved 24-28min run times, but ...

A Predictive Model of Adolescent Persistence in Counseling

A Predictive Model of Adolescent Persistence in Counseling

Date: May 2015
Creator: Holm, Jessica M.
Description: Adolescence is a developmental period characterized by profound social and emotional changes. Counseling can serve as a protective factor for decreasing the long-term negative emotional effects. Despite this fact, counselors continue to struggle with high rates of attrition among adolescent clients. When examining trends of client persistence in counseling across the lifespan, researchers found a relationship between the presence of internalizing and externalizing behaviors. Additionally, they found that high levels of familial stress predicted premature termination from counseling. The purpose of the current study was to create a predictive model of adolescent persistence in counseling. I examined both personal and environmental characteristics of adolescents who sought counseling services (N = 72) from an on-campus university counseling clinic that serves as a training facility for master’s and doctoral students at an accredited counselor education program in the southwestern United States. Participants were predominantly White (67.6%, n = 50), with a mean age of 14.23 (SD = 1.65). Nearly 60% (n = 44) of the clients were female, and 37.8% were male (n = 28). Beyond descriptive variables, eight predictor variables were examined: adolescent involvement in their intake, time spent on the wait list, four domains of parental stress, and parent perceptions ...
