The millennial generation is said to consist of all those born between the years of 1978 and 1996. The majority has come of age and has the ability to be active participants in the political community. For the past three elections they have been the democratic party biggest supporters. In the 2008 presidential election 68% of all Millennial voters voted for Barack Obama. Millennials are also reporting to be less religious and more spiritual.

Show moreThe millennial generation is said to consist of all those born between the years of 1978 and 1996. The majority has come of age and has the ability to be active participants in the political community. For the past three elections they have been the democratic party biggest supporters. In the 2008 presidential election 68% of all Millennial voters voted for Barack Obama. Millennials are also reporting to be less religious and more spiritual. They are attending religious services less frequently and identify with religious denominations less often. Throughout American history, religion is known to have an effect on political ideologies. So with Millennials religiosity changing, does their religiosity have any effect on their political ideology? The purpose of my research is to examine the religious ideologies of Millennials and see how they are affecting their political ideologies. To collect my data I have surveyed 380 Millennials. I choose to take a quantitative approach to this research project and use statistics as the basis of my analysis. My research is important to my discipline as well as my society because it closes the gaps between existing research of the Millennial generation. This research also contributes to literature because it is important to understand the political and religious views of the upcoming generation. Millennials have the ability to make huge political statements, and their decisions, attitudes, and behavior will significantly impact the future of the United States.

Self-advocacy for students with disabilities was noted throughout the literature as a necessary element for student success (Brinckerhoff, 1996; Daly-Cano, Vaccaro, (&) Newman, 2015; Gould, 1986; Williams (&) Shoultz, 1982). The literature also found that self-advocacy was particular crucial as students entered higher education (English, 1997; Stodden, Conway, and Chang, 2003; Vaccaro, Daly-Cano (&) Newman, 2015).

Show moreSelf-advocacy for students with disabilities was noted throughout the literature as a necessary element for student success (Brinckerhoff, 1996; Daly-Cano, Vaccaro, (&) Newman, 2015; Gould, 1986; Williams (&) Shoultz, 1982). The literature also found that self-advocacy was particular crucial as students entered higher education (English, 1997; Stodden, Conway, and Chang, 2003; Vaccaro, Daly-Cano (&) Newman, 2015). In regard to student persistence, academic advising was the most cited student service (Hossler (&) Bean, 1990). Academic advisors assist students through their academic journeys and are tasked with assisting students to navigate college life (Kuh, 2008). However, there was a lack of research regarding the relationship between advisors, students with disabilities, and self-advocacy. Therefore, this research study was conducted to explore the insights and support of self-advocacy among academic advisors when working with students with disabilities. A qualitative phenomenological research design was used to explore these experiences.From the data analysis, seven themes emerged after the interviews and a focus group, which represented the needs of academic advisors for their specific roles and interactions. The themes were lack of knowledge, accommodations, transition, academics, fear of being labeled, relationships and interactions, and self-awareness. The information gathered through this study may lead to professional development programs to improve relationships between academic advisors and students with disabilities and to prepare students with disabilities to become strong self-advocates.

Show moreThis thesis will analyze the Congo from King Leopold II's Free State to the 2nd Congo War. After a thorough investigation of the colonial period, this thesis will analyze the modern period. This thesis contends that the underdevelopment of the Congo, and its continuing warfare and poverty are the consequences of an exploitative colonial history. To be sure, King Leopold II of Belgium created the template for administering the Congo through the installation of concessionary companies that were more interested in harvesting huge profits than creating the conditions for a self-sustaining Congolese economy. Indeed, the policies implemented by King Leopold not only created the framework for the exploitation of the Congo after the cessation of the Free State, and set the stage for Congo's current state of instability of warfare.

Show moreThe benefits of being curious continue beyond infancy and early childhood. Curiosity has been linked to academic achievement, memory, and lifelong learning. Yet curiosity type behaviors in academic settings are infrequently observed. This is a concern because some of the students graduating from the educational system will be the teachers responsible for fostering conditions that spark curiosity and exploration for future students. These prospective teachers' lived curiosity experiences will influence their future teaching beliefs and practices. Yet few studies have been conducted that illuminate the lived curiosity experiences of prospective teachers.The research question that guided this study was, what are the lived curiosity experiences of traditionally-aged freshmen pursuing a degree in education? A phenomenological-based approach was chosen to uncover and examine prospective teachers' prior curiosity-related experiences. Using purposive and criterion sampling methods, 13 participants were recruited from foundational education courses. Rich descriptions of participants' curiosity experiences were obtained by conducting semi-structured interviews composed of open-ended questions. Using Moustakas's modified Stevick-Colaizzi-Keen method, data from the verbatim transcriptions were examined and analyzed. Seven themes were extrapolated from the data that were woven throughout four phases of curiosity. The themes revealed that participants' curiosity experiences included exposure to novel information or novel perspectives that sparked feelings or states of being that were both positive and negative. The participants' curiosity prompted them to explore the objects of their curiosity in independent and social activities that were often supported by individuals who provided autonomy and joined them in their exploration. Furthermore, every participant shared at least one experience in which people were the object of their curiosity. People, with whom participants shared a relationship founded on mutual respect and trust, were also instrumental in cultivating conditions that encouraged curiosity and exploration. The findings have implications for researchers, K-12 educators, and individuals responsible for preparing prospective teachers who are interested in exploring further, through research or practice, the potentiality of fostering curiosity.

Show moreThis dissertation in practice utilized a sequential mixed methods research design to investigate the performance or exclusion of instructional design activities commonly prescribed by instructional design models during a typical instructional design project. The purpose of this study was to compare the performance of instructional design activities by practicing instructional designers with the performance of an experienced instructional designer to determine if instructional design models are being used to guide the practice of instructional design. In this study, quantitative data was collected from a sample of 224 instructional designers to determine the activities routinely performed and excluded from typical projects. Qualitative data was collected from a single case study of an instructional design project to assess whether or not the performance or exclusion of the same instructional design activities were identified in the work of an experienced instructional designer. Analysis of the data revealed the activities that are not routinely performed by instructional designers, reasons for the exclusion of activities, and possible factors for the decisions to exclude activities.The findings of this study indicate instructional designers may be sacrificing the quality and effectiveness of instruction in an attempt to increase the pace and reduce the cost of the instructional design process. The study concluded that instructional designers are not following the prescriptions of instructional design models during the practice of instructional design by routinely eliminating the fundamental activities involving the development of learner assessments, the performance of formative evaluations during the instructional design process, and summative evaluations after the implementation of the instruction.

Show moreGender discrimination and work motivation are two important constructs for employers to consider. Changing workforce trends towards a more diverse workforce make understanding discrimination in the workplace more important than ever. And, established direct relationships between motivation and performance make understanding motivation key to organizational success. The purpose of this study was to examine the relationships among perceived gender discrimination at work, work motivation, and performance. Although much theory and research exists regarding motivation and performance, this study uses a new measure of motivation based on the Pritchard and Ashwood (2007) theory of work motivation. It was hypothesized that perceived gender discrimination would be negatively related to motivation, and that motivation would be positively related to performance. It was further hypothesized that motivation would mediate the relationship between perceived discrimination and performance. Consistent with social identity and attribution theory, gender identification was examined as a moderator of the relationship between perceived discrimination and motivation. Additionally, race and locus of control were examined as moderators of this same relationship. Measures of study variables were surveys administered on-line to 170 female undergraduate students. Upon completion of this part of the study, participants were emailed a link for their supervisors to complete on-line measures of participants' overall motivation and performance at work. Results indicated that both overall motivation and action-to-result motivation connections were negatively related to perceived gender discrimination. However, other motivation connections were not related to this discrimination. Furthermore, overall motivation and the motivation connections had strong relationships with performance. Despite the practical significance of these relationships, they did not reach statistical significance because of the small sample size of supervisor performance ratings (n = 37). Neither race, work locus of control, or gender identification significantly moderated hypothesized relationships. Additionally, there was no significant relationship between discrimination and performance, and so work motivation could not mediate this relationship. Reasons for non-significant results are discussed, as are implications for theory and practice. Although moderator hypotheses were not supported, this research represents an important step in discrimination research because it examines the possible influence of perceived discrimination on those who are impacted by it. This study also reaffirms the relationship between motivation and performance using Pritchard and Ashwood's (2007) theory of motivation.

Show moreCase study design, employing qualitative research methods, was used to document and examine a mandatory service-learning program at a new, comprehensive, public university. The study examined service-learning from multiple perspectives. Institutional theory provided a framework for examining the influence of the environment on the conceptualization, adoption, and implementation of service-learning. Program theory was used to identify and analyze the program's conceptual underpinnings, including goals and objectives, intended outcomes for students, and program processes. Knowledge of how a program is supposed to work is useful for developing assessment questions, evaluating institutional effectiveness, and improving program performance. The study included a review of the history of service-learning at the university. Data were collected during the fall 2005 semester and were analyzed using both process and variance modes. Data sources included the following: 35 documents, which spanned the years 1991-2005; interviews with seven faculty members and four academic administrators; and observations of three meetings of service-learning courses, a Government and Not-for-Profit Service Learning Job Fair, and five meetings where service-learning was a primary topic of discussion. Previous studies served as the basis for the following researcher-developed constructs used to code text across data sources: social/civic outcomes, personal outcomes, learning outcomes, and career outcomes. Findings suggest that the goals and outcomes associated with service-learning found in university documents clustered around social and civic involvement, while outcomes reported by faculty during interviews focused on students' personal development and learning related to course content. In general, university documents contained goals and objectives written in vague language, a finding consistent with previous studies.

Show moreThis research seeks to determine if there is a third-person effect in the realm of controversial product advertising. A questionnaire was designed based on previous research and distributed to a convenience sample of college students at the University of Central Florida. Participants were asked to rate their perceived levels of personal offense to product categories as well as the expected levels of other groups of people. The results show that there is indeed a significant third-person effect recognized for all product categories except for racial extremist groups. A first-person effect was shown to be present for the category of racial extremist groups. This research also suggests that a concealed third-person effect may have been present in previous studies of this nature that obtained high levels of offense attributed to the self. Discussions of the findings, implications for marketers and advertisers, limitations to the study, as well as suggestions for future research are also posited.

Show moreThe purpose of this investigation is to contribute to the body of knowledge in the area of effective time management skills among African American and Hispanic male student athletes and their academic achievement utilizing the Educational Longitudinal Study of 2002 (ELS: 2002) Base year thru the First follow-up database. The researcher has assessed indicators (socioeconomic status, time use patterns, sports participation, and race) within the construct of academic achievement among African American and Hispanic male high school student athletes. Their contribution to the main effects revealed that statistically significant differences exist between the non-sports participant and sports participant groups. After controlling for time spent completing mathematics homework and socioeconomic status, the findings revealed that time spent completing math homework was significantly related to academic achievement for African American and Hispanic male student athletes. Time spent watching television was not significantly related to academic achievement for African American and Hispanic male student athletes. For the variable time spent playing on the computer game, the analysis indicated that the detrimental effect of time spent playing video/computer games was the same for African American and Hispanic male student athletes. Finally, it is noteworthy that effective use of time (i.e., playing video games less) and sports participation positively influences academic achievement of African American and Hispanic males high school student athletes. Strategies were uncovered for possible future research among African American and Hispanic male student athletes to increase academic achievement levels.

Show moreThis study describes the perceptions of both distance education administrators and faculty who teach mathematics online in a Florida community college setting with regard to the relative importance of core competencies and roles in teaching online courses and the need for professional development that is supportive of these competencies and roles. The perceptions of administrators and online faculty for level of importance indicated for core competencies and skill area needs for faculty development when teaching an online course were examined. Results of these perceptions by group were re-examined in relation to gender, age, ethnicity, years of community college teaching experience, and years of online community college teaching experience. The Survey of Competencies for Teaching an Online Course, a 23-item instrument designed by the researcher, was mailed to 28 distance education administrators with membership to the Florida Distance Learning Consortium (FDLC) and 100 faculty teaching mathematics or statistics online during spring term 2006. Twenty administrators and fifty-two online faculty returned surveys, for a usable response rate of 71% and 52%, respectively. Results from the study suggested: (a) distance education administrators and online faculty ascribed a similar level of importance to core competencies and roles for teaching an online course; (b) providing grades and feedback, facilitating online activities to support learning, and creation of online assignments and tasks were perceived to be the most important competencies and roles for online instruction; (c) distance education administrators and online faculty ascribe varying levels of importance to skill areas needed for faculty development to support a fully Web-based course; (d) knowledge of distance education instructional techniques and planning and instructional design skills were perceived to be the most important skill area need to target for faculty development; and (e) neither gender nor age had any bearing on distance education administrator and online faculty perceptions of the need for faculty development to support online instruction. The results further indicate that although the perceived importance of core competencies and roles for teaching online were similar for distance education administrators and online faculty, the levels of importance for each competency and role varied within each group based upon gender, age, ethnicity, years of community college teaching experience, and years of online community college teaching experience. For example, male faculty, more so than female faculty, viewed greater relevance for production of new and relevant knowledge as competency. Distance education administrators between the ages of 30 and 40, more so than administrators between 49 and 55 years old, consider facilitating to understand course content a high priority competency. Recommendations for further study included conducting a parallel study by varying the faculty subject area, the institution type, geographic location, or level of accreditation. Further research is also suggested to examine ethnic minority representation within distance learning. For this study, the distance education administrator sample was just above 5%, and it was only 10% among the online faculty as it relates to ethnic minorities. Further research is needed to analyze the factors contributing to overall under-representation of ethnic minorities, particularly African-Americans.

Show moreIn the modern world, gas turbines are widely used in aircraft propulsion and electricity generation. These applications represent a massive use of energy worldwide, so even a very small increase in efficiency would have a significant beneficial economic and environmental impact. There are many ways to optimize the operation of a gas turbine, but a fundamental approach is to increase the turbine inlet temperature to increase the basic thermodynamic efficiency of the turbine. However, these temperatures are already well above the melting temperature of the components. A primary cooling methodology, called film cooling, creates a blanket of cool air over the surface and is an effective way to help protect these components from the hot mainstream gasses. This paper focuses on the effect of the film holes upstream of the first row of blades in the turbine because this is the section that experiences the highest thermal stresses. Many factors can determine the effectiveness of the film cooling, so a complete understanding can lead to effective results with the minimum flow rate of coolant air. Many studies have been published on the subject of film cooling, but because of the difficulty and expense of simulating turbine realistic conditions, many authors introduce vast simplifications such as low speed conditions or linear cascades. These simplifications do not adequately represent the behavior of a turbine and therefore their results are of limited use. This study attempts to eliminate many of those simplifications. The test rig used in this research is based on the NASA-GE E3 design, which stands for Energy Efficient Engine. It was introduced into the public domain to provide an advanced platform from which open-literature research could be performed. Experimental tests on a transonic annular rig are time-consuming and expensive, so it is desirable to use experimental results to validate a computational model which can then be used to extract much more information. The purpose of this work is to create a numerical model that can be used to simulate many different scenarios and then to apply these results to experimental data.

Show moreThis study focuses on multi-jet impingement for gas turbine geometries in which the objective is to understand the influence of the roughness elements on a target surface to the heat transfer. Current work has proven that implementing roughness elements for multi-jet impingement target surfaces has increased heat transfer ranging anywhere from 10-30%. This study has chosen to investigate three different roughness elements, elliptical in cross-section, to compare to smooth surface geometries for multi-jet impingement. An experimental was taken for this study to extend the current knowledge of multi-jet impingement geometries and to further understand the heat transfer performance. A temperature sensitive paint (TSP) technique was used to measure the heat transfer on the target surface, in which the local temperature was measured to estimate area averaged heat transfer coefficient (HTC) and row averaged HTC. In order stay consistent with literature, non-dimensional parameters were used for geometry locations and boundaries. For this study, the Reynolds number range, based on jet diameter and mass flux, is 10-15k. The X/D (streamwise direction), Y/D (spanwise direction), Z/D (channel height direction), L/D (thickness of the jet plate) constraints for this study are 5, 6, 3, and 1 respectively. From the local heat transfer distributions of the different roughness elements, it is concluded that the inclusion of these elements increases heat transfer by 2-12% as compared to a flat/smooth target plate. It is therefore recommended from this study, that elements, elliptical in shape, provide favorability in heat transfer for gas turbine configurations.

Experiment 1 focused on the differences in creative and critical thinking skills in freshman versus senior undergraduate engineering students. Experiment 2 centered on the variation in the effects of long-term versus short-term creativity training on senior engineering students. Creative skill was measured using the Test for Creative Thinking (-) Drawing Production (TCT-DP) developed by Urban and Jellen (2010). Measurements for critical thinking utilized the Watson-Glaser Critical Thinking Assessment (WGCTA) (Watson (&) Glaser, 2008).Experiment 1 found evidence suggesting the freshman engineers within the study were more creative than senior engineers (F = 3.159, P-Value = 0.078). Surprisingly, there was no evidence suggesting the senior engineers had superior critical thinking skills over the freshman engineers (F = 1.054, P-Value = 0.306). The study groups' data was also compared to the normative data provided by the WGCTA test, in order to determine the standing of the two engineering sample groups against the general population. The study's freshman group average ranked in the 70th percentile (freshman engineers' average) when compared to the normative general population's average (50th percentile). The senior participants, on the other hand, scored significantly lower than their corresponding normative group, moving from the 50th percentile (normative average) to slightly above the 35th percentile (senior engineers' average). Based on this evidence, current engineering education methods are detrimental not only to the creative skills of engineering students, but their critical thinking capabilities as well.Experiment 2 results suggested that long-term creativity training provides statistically significant improvements over short-term creativity training (F = 40.381, P-Value = 0.000). This significance was established even though the long-term group was found to have been trained inadvertently before the start of their official training, simply by their knowledge of the course's requirements to provide creative solutions. As such, these results suggest both that continuous creativity training benefits the recipient individuals, and that beginning a more creative approach to collegiate engineering curricula may start as easily as initiating courses with the known expectation that students use creativity in their problem solving whenever feasible. This study provides new insights into the state of creativity and critical thinking in undergraduate engineers. Based on the resulting data, engineering education must be examined and restructured to provide students with the necessary tools to improve their creative and critical thinking skills. Through the use of creativity and critical thinking training and instruction methods, educators can effectively address these observed deficiencies, resulting in engineering students being better prepared for their professional lives within the 21st century workplace.

Show moreFlow boiling heat transfer allows for the dissipation of large amounts of heat. In this work, the effect of heat flux and pressure on flow boiling of liquid refrigerant R-134a is studied in a vertical thin channel. The experimental setup mimics a refrigeration cycle and specifically looks at the effect of pressure and wall heat flux on the departure size and bubble generation rate. The experimental setup consists of a closed loop which includes a vertical narrow rectangular channel and two synchronized high speed cameras for optical measurements at either sides of the channel. The setup is built to employ an accurate measurement technique to define wall temperatures of the representative flow boiling process. Instead of using thermocouples on the surface channel, the thermochromic liquid crystallography (TLC) technique is used to determine non-invasively the heater surface temperature at high temporal and spatial resolution. The TLC interval range is 30-50(&)deg;C. The TLC is attached to a Fecralloy heating section. The high speed Prosilica cameras simultaneously capture, colored TLC images as well as bubble nucleation and departure at very high frame rates. Experiments on subcooled flow boiling heat transfer have been conducted with refrigerant R-134a under a mass flux range of 484.838 kg/m2s to 1212.1 kg/m2s. With the low mass flux, the wall heat flux ranged from 167.2 to 672.1 kW/m2, the inlet subcooling ranged from 0.35(&)deg;C to 16.55 (&)deg;C, the system pressure ranged from 621 kPa to 1034 kPa. At high mass flux, the wall heat flux ranged from 329.8 kW/m2 to 744 kW/m2, the inlet subcooling from 0.16(&)deg;C to 17.21 (&)deg;C, and the system pressure from 621 kPa to 1034 kPa. A parametric study was done by maintaining various input parameters constant.From the high speed images, bubble parameters such as size and frequency are calculated. Temperature contours are utilized to determine the surface wall temperature at specific points. Sequential wall temperatures are traced over a short period of time to understand the cooling effects. The bubble propagation and coalescence are also visualized. Results show that bubble size and frequency increased with heat flux at any particular pressure. At higher pressure, the trend would be for the bubble size to decrease; however, the inlet subcooling and heat flux also affect bubble size. The bubble frequency is also seen to be affected by the inlet subcooling and the heat flux. Even though the inlet subcooling is maintained approximately constant, any slight decrease in subcooling increased bubble growth rate. Another trend that is observed is that at higher the heat flux, the bubble generation frequency is faster; however no specific trend is observed for wall superheat. With an increase in heat flux, the wall superheats are expected to increase; however, the localized nature of the nucleation activity sites is seen to affect the results. The variables are non-dimensionalized to note trends in parameters. In summary, the data analysis demonstrates that both heat flux and pressure significantly influence the bubble generation rate, size, propagation and coalescence.

Show moreThis research focuses on examining the neurological similarities between schizophrenia and major depressive disorder with psychotic features in order to compare the manifestations of psychosis in each disorder. Both disorders often involve symptoms of psychosis, although the overall disorders are very different from each other. The hypothesis for this research is that the neurological similarities between schizophrenia and major depressive disorder with psychotic features will provide researchers with the strategies needed to develop a treatment for psychotic symptoms. In order to test this hypothesis, five related studies were gathered for each disorder, and three studies were gathered for psychosis. These studies were then analyzed to pinpoint any similarities among factors for psychosis, and this analysis allowed for the determination of whether or not the hypothesis would be rejected. The results indicated that a lot of the similarities between the two disorders cannot be verified because of the lack of substantial research.

Chronic pain affects nearly 48 million Americans (Haggard, Stowell, Bernstein, & Gatchel, 2008). Established guidelines for pain management encourage the use of personality assessment in chronic pain evaluation (Karlin, Creech, Grimes, Clark, Meagher, & Morey, 2005). In relation to the Big Five personality factors, low Openness relates negatively to treatment success, (Hopwood, Creech, Clark, Meagher, & Morey, 2008), and elevated Neuroticism scores also correlate with increased pain levels...
Show moreChronic pain affects nearly 48 million Americans (Haggard, Stowell, Bernstein, & Gatchel, 2008). Established guidelines for pain management encourage the use of personality assessment in chronic pain evaluation (Karlin, Creech, Grimes, Clark, Meagher, & Morey, 2005). In relation to the Big Five personality factors, low Openness relates negatively to treatment success, (Hopwood, Creech, Clark, Meagher, & Morey, 2008), and elevated Neuroticism scores also correlate with increased pain levels among individuals in hospital or rehab settings (Ashgari & Nicholas, 2006; Nitch & Boon, 2004). In contrast to these prior studies, this study identifies correlates in a relatively high-functioning population (college students) to further elucidate the connection between chronic pain and personality. This study compares scores on the NEO-FFI (Costa & McCrae, 1992), the West Haven-Yale Multidimensional Pain Inventory (WHYMPI, Kerns, Turk, & Rudy, 1985), and the Pain Catastrophizing Scale (PCS, American Academy of Orthopaedic Manual Physical Therapists, 2010). Significant correlations were found between Neuroticism, Extraversion, and Agreeableness and select subscales of both the WHYMPI and the PCS. A linear regression of scores showed that Neuroticism was very strongly related to WHYMPI scores. In fact, the WHYMPI scores accounted for 67.9% of variance in Neuroticism. Scores on the WHYMPI also correlated with PCS scores. Helplessness and Overall scores significantly correlated to Life Control and certain positive social support scores. The findings of this study emphasize the need for pain clinicians to incorporate psychological assessments, especially concerning Neuroticism, into their evaluations of chronic pain patients.

Researchers have long explored the importance of family involvement in children's academic success, communication between home and school is an important link in the process. The exploration of possible relationships were addressed using the chi-square test of association. It was anticipated that there would be a difference between the responses of staff and parents of children from Title I and those from Non-Title I schools.

Show moreThe impact that a teacher can have on their students is monumental. Teachers often are the only consistent figure of authority that a student sees. Therefore, a vulnerable and conformable environment is crucial for students, so they can share their needs and in return have them met. With this in mind, teachers must consider forming their classroom environment, because of how it is received by the students. This study examined the impact that a teacher's disposition can have on the response of a student through a six-question interview by analyzing the number of words spoken by the students depending on the disposition of the teacher used to ask the question. This study aimed to identify the possible impacts of teacher disposition on student responses using a sample of 17 elementary aged students attending a summer reading clinic at a Florida university. After a face-to-face, six-question interview was administered to the students, results showed some students made a overall shift towards more words spoken when the question was asked in an interested or neutral disposition. These results demonstrate the potential impact of teacher disposition on student response in the classroom. The results of this study complement past research, which has shown that classrooms in a welcoming and comfortable environment are more likely for students to share their needs, leading to success for both students and teacher.
