Thermal systems often feature composite regions that are mechanically mated. In general, there exists a significant temperature drop across the interface between such regions which may be composed of similar or different materials. The parameter characterizing this temperature drop is the thermal contact resistance, which is defined as the ratio of the temperature drop to the heat flux normal to the interface.

Show moreThermal systems often feature composite regions that are mechanically mated. In general, there exists a significant temperature drop across the interface between such regions which may be composed of similar or different materials. The parameter characterizing this temperature drop is the thermal contact resistance, which is defined as the ratio of the temperature drop to the heat flux normal to the interface. The thermal contact resistance is due to roughness effects between mating surfaces which cause certain regions of the mating surfaces to loose contact thereby creating gaps. In these gap regions, the principal modes of heat transfer are conduction across the contacting regions of the interface, conduction or natural convection in the fluid filling the gap regions of the interface, and radiation across the gap surfaces. Moreover, the contact resistance is a function of contact pressure as this can significantly alter the topology of the contact region. The thermal contact resistance is a phenomenologically complex function and can significantly alter prediction of thermal models of complex multi-component structures. Accurate estimates of thermal contact resistances are important in engineering calculations and find application in thermal analysis ranging from relatively simple layered and composite materials to more complex biomaterials. There have been many studies devoted to the theoretical predictions of thermal contact resistance and although general theories have been somewhat successful in predicting thermal contact resistances, most reliable results have been obtained experimentally. This is due to the fact that the nature of thermal contact resistance is quite complex and depends on many parameters including types of mating materials, surface characteristics of the interfacial region such as roughness and hardness, and contact pressure distribution. In experiments, temperatures are measured at a certain number of locations, usually close to the contact surface, and these measurements are used as inputs to a parameter estimation procedure to arrive at the sought-after thermal contact resistance. Most studies seek a single value for the contact resistance, while the resistance may in fact also vary spatially. In this thesis, an inverse problem (IP) is formulated to estimate the spatial variation of the thermal contact resistance along an interface in a two-dimensional configuration. Temperatures measured at discrete locations using embedded sensors appropriately placed in proximity to the interface provide the additional information required to solve the inverse problem. A superposition method serves to determine sensitivity coefficients and provides guidance in the location of the measuring points. Temperature measurements are then used to define a regularized quadratic functional that is minimized to yield the contact resistance between the two mating surfaces. A boundary element method analysis (BEM) provides the temperature field under current estimates of the contact resistance in the solution of the inverse problem when the geometry of interest is not regular, while an analytical solution can be used for regular geometries. Minimization of the IP functional is carried out by the Levenberg-Marquadt method or by a Genetic Algorithm depending on the problem under consideration. The L-curve method of Hansen is used to choose the optimal regularization parameter. A series of numerical examples are provided to demonstrate and validate the approach.

Show moreThis action research study summarizes the investigation of journal writing and cooperative grouping with 8th grade geometry students in the construction of proof. Students written responses to prompts in journals were analyzed over the course of twelve weeks. Case studies of four students were developed from the researchers' three geometry classes. All four students in the study participated in an academic program called Pre International Baccalaureate Preparation. Standardized test scores and an attitude scale categorized the four students. The ATMAT survey (Appendix A) measured each student's attitude toward mathematics. Writing prompts focused on the students' perceptions of the group process in constructing proofs and the development of geometric proof. The results suggested the students were engaged in learning within their cooperative groups but they also desired individual time before coming to a group setting. In addition, students' written responses to journal prompts may provide an informal assessment and help students convey their own understanding of proof before any formal assessments.

Show moreFlorida Technological University College of Engineering Thesis; One of the problems associated with the automatic image processing of satellite photographs such as weather maps is the need for image registration; that is, the fitting of a map that has some translational and rotational bias to a known data base. This paper investigates a least square method of image registration using an image that has been converted into a boundary map with a pixel representation 1 for land, -1 for water and zero for cloud pixels. A sampled correlation array is constructed by shifting the weather map to locations on a given grid, centered around a sampled correlation peak, and performing an accumulation of the pixel-by-pixel comparisons between the weather map and its data base over the whole map or a smaller search window. A least square approximation 0 f the translational and rotational bias is performed using the data from this sampled correlation array, fitted against the shape of an elliptical cone.

Show moreThis study examined how employees of the hotel industry perceived green practices. Data was collected from 220 employees working in eight green certified hotels in Orlando. Research results revealed that performance levels of green practices implemented by hotels were lower than the importance levels of those same green practices as perceived by hotel employees. The results of the study illustrated that (1) the employees' perception regarding green practices was not different than one of hoteliers in terms of importance and performance, and (2) employees weighted the green practices that were beneficial to them as more important than green practices that required their behavior change. Also, a positive correlation between organizational commitment and green practices detected in this study which suggests that hotel organizations may anticipate positive ramifications of green practices in relation to HR approach when they embrace green practices. Unfortunately, employees' green perceptions at work were not generalized by their demographic characteristics, yet a number of considerable results were garnered from this study. These were (1) employees in operational departments were more green conscious than employees in other departments, (2) generation X was critical about green performance by the hotels, and (3) minorities showed more green concerns than other ethnicities. This study suggests that hotels need to spend more time and effort in communicating their green practice to employees. Training to improve green practices should be versatile and job-specific with strategies developed to motivate the employees to engage in green practices. Overall, this study proposes for hotels simply deploying green practices is not enough. They should carefully plan their green practices by training and motivating employees.

Show moreResearch in several domains has shown that the implementation of computerized decision support aids is often associated with issues of human-automation interaction, which can have disastrous consequences. One often-cited reason for these issues is the poor quality of the feedback that is provided to the operators through these tools. The objective of the proposed investigation is to examine how providing feedback through a decision support tool affects operator knowledge and performance in the context of a fault management task for naval gunfire support. A one-way between-groups comparison was made to investigate differences between providing decision support feedback (logic trace, mission impact, both, no feedback) in a fault management task. Logic trace feedback was posited to provide users with a representation of the logic that the decision support tool used in reaching a conclusion about the best course of action to perform and is posited to support better diagnostic performance. Mission impact feedback was posited to provide the operator with a description of the potential effects that a taking a course of action will have on the pre-planned mission and is expected to support better prognoses of the outcome of a particular fault. Finally, providing both feedback types was posited to support better compensatory actions for fault situations. Results indicated that decision support feedback has potential improve diagnosis and decrease errors of commission in these tasks.

Show morePlacement into educable mentally handicapped (EMH) programs is necessary for some students in order to allow them the opportunity to receive an education appropriate for their special needs. Nonetheless, identification as EMH is often perceived as negative and demeaning. Decades of research have substantiated the over-representation of black students into certain categories of special education, including EMH, in comparison to white and Hispanic students. This disparity has raised questions within schools, academe and research communities, and legislative and governing bodies as to the causes, compelling factors, and related variables impacting the phenomenon. This study investigated the apparent over-representation of blacks identified as EMH in the 67 public school districts in Florida in 2001-2002. It also analyzed the effects certain school district characteristics had on the identification of white, black, and Hispanic students as EMH. Analysis of data derived from the Florida Department of Education database for school year 2001-2002 led to the following findings: (1) there was over-representation of blacks in EMH within the 67 public school districts in Florida, since results showed that blacks were identified as EMH 2.5 times more often than whites and Hispanics; (2) socioeconomic status of school districts had a significant effect on the identification of black students as EMH,for example, when the school district was identified as a high socioeconomic status district, there was a greater likelihood that a larger proportion of black students would be identified as EMH; (3) as the wealth of school districts rose, there was a significant likelihood that the proportion of black students identified as EMH would also rise; (4) black students had a greater likelihood of being identified as EMH in suburban school districts; (5) blacks were over-identified in school districts that had 60,000 to 89,000 students; (6) when there was a high percentage of white, full-time, non-instructional staff (80% or more) in school districts, blacks had a greater likelihood of being over-identified as EMH; (7) blacks were three times more likely to be identified as EMH regardless of the type of degrees teachers had; and, (8) as district expenditure per student (FTE) increased, the tendency for over-identification of blacks as EMH decreased. For every variable analyzed, the proportion of black students identified as EMH was significant when compared to the proportions of white and Hispanic students also identified as EMH.

Show moreABSTRACT A major change in longstanding police organizational behavior is increasingly evident in the recent emergence of computerized information-sharing networks in public safety. From both theoretical and empirical perspectives, a better understanding of the determinants that can explain and predict the rise and growth of this new and significant development in American policing is needed. A highly limited body of empirical studies has endeavored to validate effective predictors of adoption and utilization of electronic information-sharing networks by local law enforcement agencies. Utilizing an integrated theoretical framework largely built upon Rogers' diffusion of innovations theory, sixteen hypotheses were tested through logistic regression and multiple regression analyses of survey research data collected from local law enforcement executives in the three states of California, New York, and Georgia. Qualitative research organized and conducted through targeted telephone interviews with twenty law enforcement executives across the three study states and with responses to open ended questions within the study survey instrument aided in the examination of these hypotheses. 66.7% of the cases of agency adoption of information sharing were correctly classified by the predictors within the logistic regression model. Adoption was positively influenced by a chief executive who demonstrated strong leadership and possessed more extensive experience in law enforcement. Adoption was negatively affected by increasing the opportunity to experiment with this innovation and advancing age of the chief executive. Both quantitative and qualitative findings confirmed that law enforcement agencies that exhibited dedicated leadership are more likely to adopt information-sharing networks. 19.4-25.9% of the variation in the outcome variable of adoption was explained by the predictors within the logistic regression model. Utilization was negatively impacted by growing autonomy of police organizations within the network but benefited from innovation attributes such as the acquisition of an advantage in crime fighting capabilities and reduced complexity in employment of the information-sharing network. 9.1% of the variation in utilization of information-sharing networks could be explained by the predictor variables included within the multiple regression model. Qualitative research also cross-validated the positive effect of gaining an advantage over the criminal element as influential to utilization. A greater advantage in preventing and solving crimes, higher levels of inter-organizational trust between police agencies, and enthusiastic executive leadership were found by the qualitative inquiry to enhance both adoption and utilization. Knowing in advance which theoretically informed and empirically validated antecedents can facilitate or impede adoption and utilization of information integration networks could enable policymakers and law enforcement administrators to optimize strategies to attain successful outcomes.

Show moreA survey was sent to classroom teachers in Central Florida educating students with autism spectrum disorder (ASD) to investigate: 1) intervention practices currently used in the classroom for students with ASD; 2) if the interventions being used are evidence-based, and; 3) if there a difference in use of evidence-based interventions between teachers with the Florida Autism Endorsement and teachers without the Endorsement. A nonprobability purposive study was conducted via an email-based survey. The survey was designed using the tailored design method and was created in Qualtrics.com, an online survey software program. The survey was divided into three major sections: an intervention section which included a variety of evidence and non-evidenced-based practices drawn from the current research literature; a section focused on how teachers select the interventions they use in their classrooms; and, a demographic section. The survey was sent via email to classroom teachers registered with University of Central Florida Center for Autism and Related Disabilities. Participant inclusion criteria included: 1) currently a classroom teacher in a Central Florida, and 2) at least one student with ASD in the classroom. Forty surveys were completed for a ten percent response rate. Results indicated that a variety of evidence- based and non-evidence-based interventions were being used in classrooms. The top three reported interventions were Visual Supports (95 %), Computer Program Applications (93%), and Social Stories (73 %). Based on current empirical evidence, these top three interventions have insufficient evidence regarding their efficacy for use with students with ASD. In addition, two of the interventions reported to be used have a negative evidence base suggesting they may be harmful for some students with ASD. There were no significant differences between teachers with the Florida ASD Endorsement and teachers without the Endorsement with regard to the interventions used. Overall, the results of the study indicated a need for further research to determine which intervention practices may be the most effective for the specific needs of children with ASD.

Show moreWhile many school districts in the state of Florida have achieved unitary status and are no longer under court jurisdiction, evidence that school districts continue to practice discipline policies that result in the disproportionate suspension of Black students can be found. Despite decades of desegregation, Black students continue to experience the devastating consequences of suspension and expulsion from school. The overrepresentation of Black students in the administration of school discipline is a serious concern for school districts. This study investigated if the attainment of unitary status resulted in equity in school discipline for Black students. Additionally, the study investigated the overrepresentation of Black students in the administration of school discipline as measured by out-of-school suspensions in the secondary schools of the 67 Florida public school districts in 2005-2006. The study compared the representation of Hispanic and Multiracial students to Black students in the administration of school discipline. The study also examined the effects of grade level (6, 7, 8, and 9) on Black, Hispanic, and Multiracial students in the administration of school discipline. Analysis of the data derived from the Florida Department of Education database for school year 2005-2006 led to the following findings: (1) there was overrepresentation of Black students in secondary schools in the state of Florida and that 42 school districts were not in compliance with unitary status guidelines; (2) Black students were overrepresented in school discipline when compared to Hispanic and Multiracial students; (3) the effect of grade (6, 7, 8, and 9) was not significant in the representation of Black students in school discipline; (4) 18 Florida public school districts have attained unitary status, 16 public school districts remained under court jurisdiction, and 33 public school districts were never subject to desegregation litigation; and, (5) Black students were overrepresented in the administration of school discipline in school districts that have attained unitary status.

Show moreAltruism is loosely defined as a desire to help others as well as acts and behaviors towards that end, particularly when no expectation of personal gain or reward exists (Batson, Fultz, Schoenrade & Paduano, 1987). It seems likely that individuals who choose to pursue acareer in counseling might be doing so out of some altruistic interest; in other words a desire to come to the aid of others in distress. It has been noted as well that some individuals may enter the counseling profession based more on self-interest; for example, as "wounded healers" hoping to work on personal issues (Wheeler, 2002). Some researchers (Shapiro &Gabbard, 1996) hypothesize that overstated altruism may lead to burn-out and fatigue among some counselors whereas those who have limited altruism may have difficulties empathizing with clients. Despite the apparent relevance of altruism to counseling as a profession, very few studies have investigated the level of altruism among those in the field. The primary purpose of this study was to examine the relationship between altruism and personality variables in beginning counseling students. It is currently unclear to what extent altruism is a state (situational) vs. a trait (inherent). Grasping a greater sense of what constitutes altruistic behavior among beginning counseling students may benefit researchers in understanding the potential difficulties Shapiro & Gabbard (1996) suggest; i.e., burn-out, limited empathy or even self-gratification. The population in this study was 87 students entering a Master's degree in Counselor Education at a large, public institution in the Southeastern Unites States. The subjects completed the following assessments at orientation to their program: The Robinson-Heintzelman Inventory (an instrument designed to study altruism vs. self-interest in counselor education students), the Myers-Briggs Type Indicator (MBTI) and the Fundamental Interpersonal Relations Orientation-Behavior (FIRO-B). It was hypothesized that higher scores on altruism would correlate with the intuitive and feeling dimensions of the MBTI and low scores on wanted inclusion, wanted affection and expressed control on the FIRO-B. The hypotheses were not supported in this study; the only finding of statistical significance was the correlation between the thinking dimension of the MBTI and the total score on the RHI. Suggestions for future research are discussed.

These findings reflected recent national trend data showing shifting gratifications and an increase in technology use among older American adults. In regards to the planned mobile app, the study's respondents had favorable reactions to its potential features and indicated an above average intent toward downloading the app.

The purpose of this study was to investigate the directional relationship between student-athletes' degree of mental health stigma, help-seeking attitudes, depression, anxiety, and life stress scores. This investigation tested the theoretical model that student-athletes' (N = 621) degree of mental health stigma (as measured by the Perceived Devaluation-Discrimination Scale (-) Adapted [PDD-A; Eisenberg et al., 2009]) contributed to their attitudes towards help-seeking (as measured by the...
Show moreThe purpose of this study was to investigate the directional relationship between student-athletes' degree of mental health stigma, help-seeking attitudes, depression, anxiety, and life stress scores. This investigation tested the theoretical model that student-athletes' (N = 621) degree of mental health stigma (as measured by the Perceived Devaluation-Discrimination Scale (-) Adapted [PDD-A; Eisenberg et al., 2009]) contributed to their attitudes towards help-seeking (as measured by the Attitudes Toward Seeking Professional Psychological Help (-) Short Form [ATSPPH-SF; Fisher (&) Farina, 1995]) and levels of depression (as measured by the Patient Health Questionnaire (-) 9 [PHQ-9; Kroenke et al., 2001]), anxiety (as measured by the Generalized Anxiety Disorder - 7 [GAD-7; Spitzer et al., 2006]), and life stress (as measured by the College Student-Athlete Life Stress Scale [CSALSS; Lu et al., 2012]). Specifically, the researcher tested the hypothesized directional relationship that student-athletes with a greater amount of mental health stigma would have (a) decreased positive help-seeking attitudes and (b) increased levels of depression, anxiety, and life stress. The results of the structural equation model (SEM) analyses identified that student-athletes' amount of mental health stigma contributed to help-seeking attitudes (25.6% of the variance), but not levels of depression (.16% of the variance), anxiety (.09% of the variance), or life stress (.81% of the variance). Specifically, student-athletes' degree of mental health stigma shared a strong negative relationship (-.506) with attitudes towards seeking professional psychological help. Further, the results identified that personal stigma mediates the relationship between public stigma and help-seeking attitudes. Implications of the findings include (a) greater knowledge of the importance student-athletes' mental health stigma and attitudes toward receiving help; (b) increased understanding for counselors of student-athletes mental health needs; and (c) insight into practices for institutions of higher education as they implement mental health initiatives within intercollegiate athletics.

Show moreThe overall purpose of this study was to investigate counselor educatorsÃÂ' attitudes towards evidence-based practices (EBPs) and perceived barriers to the inclusion of EBPs in counselor education curricula. Additionally, this study aimed to assess whether counselor educatorsÃÂ' level of agreement towards the presence of motivational interviewing (MI) principles in the counseling relationship impacted attitudes towards EBPs. As such, this researcher analyzed four research questions using two instruments and a demographic questionnaire. Two hundred sixty nine counselor educators (39.8% response rate) from the Association of Counselor Education and Supervision responded to an electronic survey, which consisted of the Evidence-Based Practice Attitude Scale (EBPAS; Aarons, 2004), the BARRIERS Scale (Funk, Champagne, Wiese, & Tornquist, 1991), and a demographic questionnaire. Specifically, this study investigated four research questions to determine: (a) the difference in attitude towards adopting EBPs among counselor educators with respect to specific individual factors (i.e. specialized training in evidence-based practices, years of professoriate experience, and primary counselor education focus); (b) the difference in perceived barriers towards adopting EBPs into counselor education curricula among counselor educators with respect to organizational factors (i.e. type of program, status of CACREP accreditation, and faculty position); (c) the influence of EBP attitude on perceived barriers to the inclusion of EBPs in counselor education curricula; and (d) the correlation between counselor educators reported level of agreement towards MI principlesÃÂ' presence in the counseling relationship and their attitude towards EBPs. Multivariate analyses of variance (MANOVA) were computed to analyze the data for the first two research questions, while linear regressions were utilized to compute the data for the last two research questions. In terms of individual factors, study results indicated that neither specialized training in EBPs nor years of professoriate experience resulted in significant differences with regards to attitudes towards EBPs. However, data analysis did reveal a significant difference between counselor educators with a clinical focus and counselor educators with a vocational focus. With regards to organizational factors influence on perceived barriers to the inclusion of EBPs in counselor education curricula, analyses revealed that neither CACREP accreditation nor faculty position resulted in any significant differences. Although, analysis did reveal that counselor educators in masters only programs perceived significantly less barriers to the inclusion of EBPs than did counselor educators in doctorate granting programs. Furthermore, results suggested a negative correlation between attitude towards EBPs and barriers towards the inclusion of EBPs in counselor education curricula, and a positive correlation between counselor educatorsÃÂ' agreement towards the inclusion of MI principles in the counseling relationship and their attitudes towards EBPs. Limitations of the study, implications for this study, and recommendations for future research as it relates to EBPs in counselor education and the counseling profession are addressed.

Show moreThe focus of this research was to investigate the effects of gender and level of prior access to athletic programs sponsored by school, community, church, student or civic groups, and informal programs on level of first-time-in-college (FTIC) freshmen's interest in participating in intercollegiate athletics. To this end, 1,196 respondents (682 females and 514 males) who were admitted to the University of Central Florida and attended freshman orientation sessions in May and June of 2007 at the UCF-Orlando campus completed the face-to-face survey. Participants ranged in age from 18 years of age to 25 years of age, representing varied racial/ethnic backgrounds, with a majority being registered as full-time students at time of the survey. The FTIC freshmen anonymously and voluntarily completed a modified version of The Student Interests in Athletics, Sports, and Fitness Survey (National Collegiate Athletic Association, 1995). Quantitative data gathered through analysis of closed-response questions provided information on their demographics, general interest in athletics, prior access to school and non-school sponsored sports, and interest in participating in college athletics. Survey responses suggested that a gender difference exists in FTIC freshmen when taking into account prior access to school and non-school sponsored athletics in predicting level of interest in participating in intercollegiate sports. FTIC freshmen males reported having more access to athletics than did FTIC freshmen females prior to attending freshmen orientation sessions in May and June of 2007. In addition, more FTIC freshmen males than females reported being interested in participating in intercollegiate athletics. Lower interest and participation rates by females in intercollegiate sports may, therefore, be an artifact of less access to opportunities to participate in sports during high school.Although almost four decades have passed with the expectation of gender equity within school settings in effect, most educational institutions are not in compliance with Title IX legislation. Females have not been afforded the same opportunities to participate in sports as males, and this appears to have influenced their interest in participating in sports. The findings of this study demonstrate the need for increased enforcement of Title IX legislation at all levels of education for true gender equity and athletic interest to be realized.

In addition, this study also ventured to determine if the type of geometry course had any impact on students' logical thinking and proof construction achievement. The sample for the study consisted of 1,325 high school geometry students enrolled in regular, honors, and mastery courses in four high schools from the school district affiliated with the Local Education Agency (LEA) during the academic year 2004-2005. Geometer's Sketchpadä (GSP) was assumed to represent the dynamic geometry software. Responses of students on two pre-tests and two post-tests, each with one on logical thinking and one on proof, were analyzed to address the research questions. Results of the analyses indicated no significant effect of the yearlong geometry course on the performance of students on proof tests but a fairly significant effect on the tests of logical thinking. Use of GSP was found to have some impact on honors and mastery students' performance on proof post-tests. Honors students showed a higher logical thinking level than their regular and mastery counterparts in both GSP and non-GSP groups. There was a significant positive correlation between students' performance on the tests of logical thinking and proof.

Show moreThe issue of high school reform has received national attention during the first part of the 21st century. One idea brought forth in this restructuring effort has been the desire to create high schools with smaller student populations. However, in an era of tight budgets, where resources are not always available to build more schools, educators have explored the possibility of dividing existing large high schools into smaller units. This restructuring approach has many titles, but is frequently referred to as a Smaller Learning Community (SLC). Since 2000, the federal government has pledged $245 million to schools willing to create SLCs. This research has studied the schools in Florida that have received the federal implementation grant and have established SLCs. The 39 Florida high schools that were awarded the federal grant in 2000, 2001, and 2002 served as the population for this study. Twenty schools in the population completed a 45-item survey which measured implementation of five key SLC elements:(a) accountability, (b) autonomy, (c) identity, (d) instructional focus, and (e) personalization. Based on the survey results, an implementation score was determined for each participating school. Based on 5-point Likert scale (with a not applicable option) for the 35 questions that pertained to the five elements, a total score of 175 was the maximum amount possible. Individual responding school scores ranged from 104.7 - 157.1. The overall implementation score was also correlated with selected school indicators. Survey respondents also provided rationale for the implementation of SLCs and perceived benefits to students, teachers, and parents. In general, the survey respondents agreed that SLCs at their schools addressed the five key elements. The implementation scores and teacher comments, however, provided evidence that the levels of implementation of SLCs across the state varied in terms of the elements. Suggestions for future research and educational practices are provided
