Modeling and Analysis of Next Generation 9-1-1 Emergency Medical Dispatch Protocols
Emergency Medical Dispatch Protocols are guidelines that a 9-1-1 dispatcher uses to evaluate the nature of emergency, resources to send and the nature of help provided to the 9-1-1 caller. The current Dispatch Protocols are based on voice only call. But the Next Generation 9-1-1 (NG9-1-1) architecture will allow multimedia emergency calls. In this thesis I analyze and model the Emergency Medical Dispatch Protocols for NG9-1-1 architecture. I have identified various technical aspects to improve the NG9-1-1 Dispatch Protocols. The devices (smartphone) at the caller end have advanced to a point where they can be used to send and receive video, pictures and text. There are sensors embedded in them that can be used for initial diagnosis of the injured person. There is a need to improve the human computer (smartphone) interface to take advantage of technology so that callers can easily make use of various features available to them. The dispatchers at the 9-1-1 call center can make use of these new protocols to improve the quality and the response time. They will have capability of multiple media streams to interact with the caller and the first responders.The specific contributions in this thesis include developing applications that use smartphone …

Motivating Pre-service Teachers to Incorporate Technology Into the Classroom
Technology integration into the classroom is a multi-faceted and complex topic. One factor that can have an effect on a teacher's incorporation of technology into their classroom is pre-service teacher technology training. In this research study the ARCS instructional design model was applied to a pre-service teacher technology course in the hopes of motivating course attendees to both learn about technology incorporation and to incorporate technology into their future classrooms. The ARCS instructional design model that relies on the motivational sub-components of attention, relevance, confidences, and satisfaction to develop instruction that motivates to students to learn course content and goals. This study analyzed a group of pre-service teachers enrolled in a university technology training course to determine if the redesign resulted in the desired outcomes. Pre-test and post-test data was collected using both quantitative and qualitative instruments to analyze the potential effect of the redesigned course.

From Aspiration to Attainment: African American Community College Transfer Student Experiences Through Baccalaureate Degree Attainment
The purpose of this dissertation was to explore African American community college transfer student experiences through baccalaureate degree completion. The current study used qualitative methods to examine the experiences and perceptions of eighteen African American community college transfer students who recently graduated or were within 30 credit hours of graduating from a four-year university in Texas. Ten female and eight male students, ranging in age from 21 to 56 years old, with an average age of 28, composed the sample. Data were collected through semi-structured interviews which were transcribed and analyzed based on an integrated conceptual model of Padilla’s (1999) Model of Minority Student Success and Yosso’s (2005) Community Cultural Wealth Model. Findings suggest that African American community college transfer student experiences are very similar to transfer student experiences revealed in current literature. However, findings indicate students perceive their experiences differ from student of other races/ethnicities when dealing with negative stereotypes, lack of role models, and racial bias. Findings also suggest African American community college transfer student persist by employing transfer student capital, familial, aspirational, and resistant capital to learn how the traverse transfer, transition, and persistence through baccalaureate degree attainment.

Mexican Mothers’ Experiences with Depression, Intimate Partner Violence, and Immigration: a Mixed Methods Study of Maternal Self-efficacy
This study investigated the relation between maternal self-efficacy, depression, and intimate partner violence among Mexican immigrant and Mexican mothers. The research was conducted using a parallel mixed methods approach including both qualitative and quantitative methods. A total of 136 mothers living in the United States and Mexico completed surveys, and 10 mothers participated in semi-structured interviews. In a regression on maternal depression, living in Mexico as opposed to the U.S., psychological violence, and maternal self-efficacy were significant predictors of maternal depression. In the qualitative data analysis, we found five main themes: perceptions, cultural influence, involvement, resources, and barriers. In this stage of the study, Mexican and Mexican immigrant mothers described in detail their experiences of being a mother, their perceptions of maternal self-efficacy, and the influence of intimate partner violence and depression on their effectiveness as mothers. Overall, Mexican immigrant families appeared to have healthier relationships and greater well-being than Mexican families.

The Masculinity Masquerade: the Portrayal of Men in Modern Advertising
The depiction of gender in advertising is a topic of continuous discussion and research. The present study adds to past findings with an updated look at how men are represented in U.S. advertising media and the real effects these portrayals have on the male population under the theoretical framework of hegemony and social cognitive theory. This research is triangulated with a textual analysis of the ads found in the March 2013 editions of four popular print publications and three focus group sessions separated by sex (two all-male, one all-female), each of which is composed of a racially diverse group of undergraduate journalism and communications students from a large Southwestern university. The results of the textual analysis reveal little ethnic or physical diversity among male figures in advertising and distinguish six main profiles of masculinity, the most frequent of which is described as the "sophisticated man." The focus groups identify depictions of extreme muscularity and stereotypical male incompetence as the most negative representations, while humorous and hyperbolic portrayals of sexual prowess and hyper-masculinity are viewed positively as effective means of marketing to men.

The Measurement of the Third-order Elastic Constants for La3ga5sio14 (Lgs) and La3ga55ta05o14 (Lgt) Single Crystal
Recently, the development of electronic technology towards higher frequencies and larger band widths has led to interest in finding new piezoelectric materials, which could be used to make filters with larger pass band widths and oscillators with better frequency stability. Langasite (La3Ga5SiO14, LGS) and its isomorphs have enticed considerable attention of researchers as a potential substrate material for piezoelectric device applications because of its high frequency stability and fairly good electromechanical coupling factors for acoustic wave devices. Nonlinear effect including drive level dependence, mode coupling, force-frequency effect and electroelasic effect are critical for the design of these devices. Third-order elastic constants (TOEC) play an important role in a quantitative analysis of these nonlinear effects. In particular these elastic constants are of great importance when the BAW (Bulk Acoustic Wave) and SAW (Surface Acoustic Wave) sensors of force, acceleration and so on are designed. Until now Langasite (LGS) and Langatate (LGT) crystal resonators have been qualified in terms of quality factor, temperature effect, isochronism defect and material quality. One of the most important advantages of those crystals is that they will not undergo phase transitions up to its melting temperature of 1450°. Presently there is no data on TOEC of LGT …

Investigating the Relationship Between Internet Attitudes of College Students and Their Stem (Science, Technology, Engineering and Mathematics) Career Perceptions
Are our students just consumers of technology or do their interests in technology translate into positive perceptions about STEM majors and careers? This research aimed to describe the role of the Internet in undergraduate students’ academic and career perceptions in STEM areas. The purpose of the research was addressed in three parts. First, the attitudes of undergraduate students towards five functions of the Internet namely tool, toy, treasure, telephone and territory were described. Second, students’ STEM career-related perceptions were described in terms of their science and mathematics self-efficacy, outcome expectations, and attitudes towards a STEM career. Third, the relationship between the five Internet functions and the three STEM career-related perceptions was examined. The participants for this study were 566 undergraduate students from a large Southern university. The research design followed a mixed methods approach using multivariate analyses and content analyses. The findings of the research indicated that there was a small but meaningful relationship between undergraduate students’ Internet and STEM perceptions. In their daily lives, the students perceived the Internet more as a toy and a tool. For general career related purposes, they perceived the Internet more as a treasure and a tool. For STEM areas in particular, they perceived …

Miniature Mass Spectrometry: Theory, Development and Applications
As mass analyzer technology has continued to improve over the last fifty years, the prospect of field-portable mass spectrometers has garnered interest from many research groups and organizations. Designing a field portable instrument entails more than the scaling down of current commercial systems. Additional considerations such as power consumption, vacuum requirements and ruggedization also play key roles. In this research, two avenues were pursued in the initial development of a portable system. First, micrometer-scale mass analyzers and other electrostatic components were fabricated using silicon on insulator-deep reactive ion etching, and tested. Second, the dimensions of an ion trap were scaled to the millimeter level and fabricated from common metals and commercially available vacuum plastics. This instrument was tested for use in ion isolation and collision induced dissociation for secondary mass spectrometry and confirmatory analyses of unknowns. In addition to portable instrumentation, miniature mass spectrometers show potential for usage in process and reaction monitoring. To this end, a commercial residual gas analyzer was used to monitor plasma deposition and cleaning inside of a chamber designed for laser ablation and soft landing-ion mobility to generate metal-main group clusters. This chamber was also equipped for multiple types of spectral analysis in order to …

Minority Stress, Spirituality and Psychological Quality of Life in a Lesbian, Gay and Bisexual Sample
Unique factors associated with the experience of spirituality and religiosity for many in lesbian, gay and bisexual (LGB) communities include minority stress. Using structural equation modeling, we examined whether minority stress mediates the relationship between spirituality and psychological quality of life (QOL). Results indicate minority stress mediates the relationship between spirituality and psychological QOL for gay men and bisexuals. However, minority stress is not a significant mediator for lesbians. Therefore, lesbians may experience minority stress and its relationship to psychological QOL differently than gay men and bisexuals due to higher societal acceptance. This study provides support for examining lesbians, gay men and bisexuals separately rather than as one sexual minority group.
