Show moreSocial policy concerns groups. Specifically, social policies have been implemented as a means to affect the well-being of sexual and gender minorities, including areas such as health, employment, violence, and many others. Undergraduate student opinions on such policies are an understudied area of survey research. Possible correlates of support for such policy areas include, but are not limited to, sexual prejudice, attributions, increased contact with the minority group, gender, Para-social contact, and many others. This research administered a 55-item survey to undergraduate students at the University of Central Florida. With a sample of 210 individuals, this study aimed to answer the following research question. Which explanatory variables are most correlated with support for social policies and rights regarding sexual and gender minorities? Dimension reduction techniques were utilized to create three sub-scales that measure the dependent variable: Alternative Relationship Recognitions, Socio-Political and Economic Goals, and Basic Freedoms. Cronbach's alpha coefficients were reported, confirming the internal consistencies of the dimensions. Bivariate correlation analyses revealed a number of variables with consistent relationships to the dependent variable: sexual prejudice, attributions that view homosexuality as something with which an individual is born, support for abortion rights, partisan identification, ideology, religious affiliation, and religious attendance. Ordinary Least Squares (OLS) regression models further assessed the nature of the relationships; sexual prejudice was the most correlated with support for social policies and rights pertaining to sexual and gender minorities. Discussions of findings, limitations of this research, directions for future research, and empirical implications are provided accordingly.

Show moreThis study queried collegiate level instructors of public speaking asking if there was a gender based difference in their attitudes and beliefs about stuttering. The survey examined for relationships between instructor level of education and: sources of knowledge, knowledge of causation and, amount of knowledge about stuttering. Communication literature searches indicated there were few, if any, studies which specifically addressed the knowledge levels, sources of knowledge and causation information for stuttering. Stuttering occurs in approximately 1% of the worldwide population so it is reasonable to expect that most collegiate level instructors would have individuals who stutter presenting in their classrooms. A Qualtrics survey, presented the Public Opinion Survey of Human Attributes (-) Stuttering, to participants across the United States who were members of the Basic Course in communication list serv or who were subscribed to CRTNET. A total of 134 individuals responded to the survey. The majority of respondents were native English speakers, with a small number speaking Spanish as a second language. Respondents represented thirty six of the fifty United States with 113 respondents reporting they actively were teaching the basic course in public speaking. Statistical analyses indicated there were no significant differences between master and doctoral level educated instructors in their: sources of knowledge; information on causation of stuttering, and; amount of knowledge about people who stutter. There were no significant differences between instructor gender and attitudes about stuttering, and beliefs about people who stutter. Findings underscored the limited amount of information which this sample of public speaking instructors possessed regarding the causation of stuttering as only 37.7% of respondents selected genetics as an underlying factor in the occurrence of stuttering. The majority of instructors reported some information to none about people who have a stuttering disorder. They indicated their knowledge was acquired through personal experiences, school, and to a lesser degree, print media.

Show moreCubeSats have become popular among universities, research organizations, and government agencies due to their low cost, small size, and light weight. Their standardized configurations further reduce the development time and ensure more frequent launch opportunities. Early cubesat missions focused on hardware validation and simple communication missions, with little requirement for pointing accuracy. Most of these used magnetic torque rods or coils for attitude stabilization. However, the intrinsic problems associated with magnetictorque systems, such as the lack of three-axis control and low pointing accuracy, make them unsuitable for more advanced missions such as detailed imaging and on-orbit inspection. Three-axis control in a cubesat can be achieved by combining magnetic torque coils with other devices such as thrusters, but the lifetime is limited by the fuel source onboard. To maximize the missionlifetime, a fast attitude control management algorithm that could optimally manage the usage of the magnetic and thruster torques is desirable. Therefore, a recently developed method, the B-Spline-augmented virtual motion camouflage, is presented in this defense to solve the problem. This approach provides results which are very close to those obtained through other popular nonlinear constrained optimal control methods with a significantly reduced computational time.Simulation results are presented to validate the capabilities of the method in this application.

I examined how allowing my students this choice influenced their attitudes, achievement, and explanations of their thought processes. I found that allowing students to choose their own manipulatives had positive influences in all three areas. Pre- and post-test results showed an overall shift toward more positive mathematics attitudes, as well as increased academic achievement with two-digit addition concepts. Students also demonstrated changes in the ways they used the manipulatives, as well as how they explained their solutions to two-digit addition problems.

Show moreHuman activities are a major driver of biodiversity degradation and loss, especially in tropical forest areas, where forest-fringe towns and villages depend on the forests for their livelihoods. In order to reduce threats that human activities pose to biodiversity, livelihoods support programs are employed as economic incentives for biodiversity conservation. These programs support the livelihoods activities of local communities, with the aim of triggering favorable attitudes and behaviors towards conservation, and ultimately reduce biodiversity degradation. Their effectiveness as conservation tools has not been evaluated. I investigated the effects of livelihoods programs on conservation attitudes and the consequent effects on biodiversity in the Afadjato-Agumatsa and Atewa forest areas in southeastern Ghana.The study areas are coupled human and natural systems, which are excellent for research in the theoretical framework of biocomplexity in the environment. Using literature reviews and field visits, I documented the specific livelihoods support activities (LSAs) used for biodiversity conservation, their historical trend and geographical distribution in Ghana. I used ex-post cost-benefit analysis to determine socio-economic estimates of the LSAs in the two forest areas. Since communities were not randomly assigned to the interventions, I employed quasi-experimental design to evaluate the effects of LSAs on environmental attitudes. I evaluated the effect of conservation attitudes on biodiversity at two levels. These levels included 1) functional biodiversity at the landscape level represented by mean Normalized Difference Vegetation Index (NDVI) of forest; and 2) compositional biodiversity at the species level represented by species diversity of fruit bats. The earliest record of LSAs used for biodiversity conservation in Ghana was in 1993. I identified 71 different activities belonging to eight categories. Some of these activities are beekeeping, animal husbandry, crop farming, and snail rearing. Most LSA programs have been in northern Ghana. There was an increasing tendency to make LSAs part of every conservation program in Ghana and this satisfies the current policy of collaborative conservation.The socio-economic estimates of LSAs included: 1) capital investment; 2) net socio-economic benefits; and 3) the benefit-cost ratio. The per-community values of the three estimates were not different between the two study areas. The per capita values of capital investment and net economic benefit were not significantly different between the two study areas. However, benefit-cost ratio per capita was higher in Afadjato-Agumatsa than in Atewa. Estimates of economic returns from LSAs were marginal but the perceptions of success were relatively high.Environmental attitudes in LSA communities and non-LSA communities were not significantly different, and this was confirmed by an estimate of infinitesimal effects of LSAs on forest conservation attitudes. Among LSA communities, benefit-cost ratio of LSAs predicted favorable forest conservation attitudes; and change in pro-conservation attitudes were significantly higher in communities that had active LSAs than in communities which had no active LSA.Mean NDVI of the forests decreased from 1991 to 2000 and decreased further but at a slower rate to 2010. Higher forest conservation attitudes predicted higher mean NDVI in 2010. Higher change in mean NDVI from 1991 to 2000 predicted higher change in mean NDVI from 2000 to 2010. Eleven of the 13 fruit bat species in Ghana were recorded in the study areas. Longer distances between a local community and its forest predicted higher species diversity of forest-specialist fruit bats.The results indicate that LSAs have become a major contribution to Ghana's current collaborative forest policy. The fact that perceptions of LSA success were moderate even though the economic returns from them were marginal suggest that other factors such as provision of employment, training in new skills and community cohesion played a part in how communities viewed the success as LSAs. Evaluations of conservation attitudes suggest that just participating in LSAs did not improve attitudes; but higher benefit-cost ratio predicted favorable conservation attitudes, and conservation attitudes were higher in communities that sustained their LSAs. Therefore, it may serve biodiversity conservation to invest in LSAs that can be sustained and involve the least costs to local communities. Primary production of the forests, a proxy for a functional habitat, continued to decrease. Preventing communities from locating closer to forests could improve fruit bat diversity, which contributes to natural forest regeneration. Improving conservation attitudes should be an objective of conservation at the landscape scale.On the basis of the results, I developed a conceptual model for forest biodiversity conservation in a biocomplexity framework. This model could be useful for evaluating conservation in tropical forest areas. Lessons from this study can be applied in other incentive-based conservation programs such as payments for ecosystem services systems and carbon market schemes. I suggest that this study be repeated after a decade and that other socio-political and biogeochemical variables be integrated into future studies.

Show moreThe overall purpose of this study was to investigate counselor educatorsÂÂ' 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 educatorsÂÂ' 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 principlesÂÂ' 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 educatorsÂÂ' 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 moreUniversity of Central Florida College of Arts and Sciences Thesis; In April 1984, at a conference convened by the National Institutes of Health, a panel of experts issued a statement listing calcium as a "mainstay in the prevention and management of osteoporosis." Osteoporosis, or "brittle bone disease," affects one out of every four American women over 5 0 and is the 12th leading cause of death in the United States. In January 1985, the National Dairy Promotion and Research Board began emphasizing dietary calcium in the promotion of milk and dairy products. Television commercials and print advertising were developed which focused on the calcium contained in dairy products and stressed the importance of this nutrient to a woman's diet. Recent consumer research conducted by Market Facts, Inc. of Chicago indicates that this positive calcium message designed to increase dairy product intake may not be effectively reaching the 13-24 year old female. The study shows that subjects in this age group report that they are doing less about their calcium deficiencies than subjects who were studied prior to the time that the dietary calcium advertising began. In addition, the research indicates that those women who are taking steps to increase calcium intake are less likely to use dairy products. Teenage females offer the dairy industry a challenging opportunity. While average male milk consumption jumps dramatically during the ages of 13-19, average female milk consumption experiences only a slight increase. Reaching this audience at this habit-forming age end changing their attitudes and behavior could provide lifelong use of dairy products. The purpose of this study is to determine the efficacy of past dairy calcium advertising messages in affecting the health attitudes and dietary behavior of 13-17 year old women in Florida.

Show moreThe purpose of this study was to determine if the use of the Equals mathematics curriculum had any statistically significant impact on the 2012 Florida Alternate Assessment mathematics scores of students with disabilities in six Florida school districts when comparing the scores of those who received mathematics instruction via the curriculum to the scores of students with disabilities in six other Florida school districts who did not receive mathematics instruction via the curriculum. This study further examined the perceptions of and attitudes about the Equals mathematics curriculum that exist among Exceptional Student Education (ESE) teachers who teach mathematics to students with disabilities participating in the Florida Alternate Assessment (FAA).The study utilized a mixed methods approach to research that included both quantitative and qualitative methodologies. The quantitative portion of the study was conducted using archival data obtained from the 2012 Florida Alternate Assessment Data Book. A Mann-Whitney U Test was conducted through SPSS at a significance level of ? = .05 to test for relative differences in performance between the treatment (Equals) and control (non-Equals) groups. Based on the results, the Equals mathematics curriculum did not have any statistically significant impact on the 2012 FAA mathematics scores for students with disabilities in the treatment school districts at any of the tested grade groupings (elementary, middle, high, and overall).The qualitative method of data collection utilized an online teacher survey. The results were analyzed using the researcher-coded results and assisted through summary tables provided by Survey-Monkey. Differences and similarities among the survey question responses were explored. Common terms and themes were noted and compared. Data triangulation was used by surveying teachers from five of the six treatment counties. This promoted generalizability for study replication since the treatment counties train teachers and utilize the curriculum in different manners. The results of the qualitative analysis indicated that many teachers were not satisfied with the training they received and felt overwhelmed by the curriculum itself, specifically in the areas of lesson planning and delivery. Based on the quantitative and qualitative results, it was concluded that further research needs to be completed to determine the effectiveness of the Equals mathematics curriculum when used with true fidelity.

Show moreThis quasi-experimental study examined the impact of interactions with native French language Facebook posts on beginning French language learners' willingness to communicate (WTC) and their attitudes towards the target language and culture in a university setting. In addition, the degree of interaction, by participants, with the French language Facebook posts was recorded and analyzed. This study was conducted during the Spring 2013 semester at the University of Central Florida in Orlando, Florida. Participants in this study were recruited from two sections of FRE 1120, Elementary French Language and Civilization I. Native French language Facebook posts were (")pushed(") to participants' personal Facebook News Feeds over the course of four weeks, with posts pushed on weekdays only and Facebook polls asking for participant feedback on Fridays. Two instruments were used in this study to obtain participants' demographic information and to measure willingness to communicate as well attitudes towards the target language and culture. In addition, the researcher gathered observational data directly from Facebook.Data were analyzed using a Split-plot ANOVA and descriptive statistics. A total of 26 participants completed the study, with 14 participants in the control group and 12 participants in the treatment group. Both sections of FRE 1120 were conducted in a traditional, face-to-face format and were taught by the same instructor. Results indicated that participants' willingness to communicate in French and their attitudes towards the target language and culture were not significantly impacted by interaction with native French language Facebook posts. The level of Facebook-facilitated interactions in all areas, including (")Liking,(") Sharing,(") and (")Commenting(") was low. Self-reported interactions, including reading, viewing and translating of French language Facebook posts; Reading and viewing posts (such as simply viewing a photo) was the most frequently reported interaction, with (")Commenting(") and (")Sharing(") was the least common interaction. Opportunities for future research are numerous and include increasing the size of the sample, increasing the length of the study, and selected participants' who are more advanced in their mastery of the target language. The potential of social network sites to serve as digitally immersive environments for foreign language learners should be explored in more depth and across various languages.

Show moreA majority of diabetes self-management programs have been shown to improve knowledge, attitude, practice, and health care outcomes. However, in the literature the underlying causal mechanisms for the improvement attributable to health education have not been explored, especially, how diabetes educational intervention may affect diabetes care outcomes. The purpose of the present study was to identify the causal mechanisms responsible for improved knowledge, attitude, practice and outcomes, so that educational interventions can be tailored efficiently and effectively to patients who are most likely to benefit from self-care management. The study used the knowledge, attitude, practice and outcome (KAP-O) framework. The specific purpose of the study was to examine the causes of variation in the outcomes of glycated hemoglobin (A1C), low-density lipoprotein cholesterol (LDLC), functional capacity (FC), and poor perceived health (PPH).An experimental study with a randomized control trial design involving 141 participants was conducted. The experimental group (N = 87) and control group (N = 52) were comparable in terms of demographics and major diagnoses. The experimental group received diabetes education. The control and experimental groups received usual customary care. Knowledge, attitude, practice, functional capacity and poor perceived health were measured before and after intervention using reliable and valid instruments. The study used a tailored attitudinal instrument. Glycated hemoglobin (A1C) and low-density lipoprotein cholesterol (LDLC) were measured before and after intervention. Multiple analytic strategies were applied to examine the experimental data.The four outcome variables of (A1C), (LDLC), (FC), and (PPH) did not constitute one common factor measurement model for outcome evaluation. Results of the Independent sample t-test showed that health educational intervention directly improves knowledge about diabetes. The path analysis of panel regression showed that health educational intervention directly lowers glycated hemoglobin (A1C). The causal modeling of {(Exp_Status)-(K-T2)-(A-T2)-(P-T2)} model showed that health educational intervention also indirectly improves preventive practice via knowledge. The effect of attitude (A-T2) was greater than the effect of knowledge on preventive practice of self-care. The difference-in-differences analysis showed that difference in practice (DP) statistically significantly affects the difference in glycated hemoglobin (DA1C). The greater the preventive practice, the greater the lowering of glycated hemoglobin (A1C), indicating a better control of diabetes. The data from this experiment do not support a strong causal path of experimental effects on outcomes via knowledge, attitude, and practice of self-care.The study should be replicated using the KAP-O model in research based on multi-centers, multiple providers, and a diverse population of Type 2 diabetes patients. The study should assess outcomes more than four times over a period of one to two years to elicit the trajectory of change in outcome variables. Knowledge and attitude should be assessed at baseline and continuously improved for the duration of the study.?

Show moreApproximately 47,700 pedestrians were killed between the years of 2000 - 2009. School buses are one of the safest modes of transportation (National Highway Traffic Safety Administration, 2004). However, the Central Florida school district eliminated bus transportation within the 2-mile radius from schools just last year. Children must prepare for an alternative mode of transportation; walking and biking. The purpose of this research was two-fold. First to develop an online safety training program for elementary school children; and second, a self-report questionnaire was constructed and piloted to measure how safety training and school infrastructure affects students' pedestrian risk-taking attitudes and risk perceptions to avoid the dangers of walking and biking to and from school. A 2x2 Factorial Multivariate Analysis of Variance (MANOVA) was used to test two categorical independent variables (safety awareness training, school infrastructure) for each of the two continuous dependent variables (pedestrian risk-taking attitudes and risk perceptions of pedestrian behavior). Using data from the pilot study, the researcher developed, self-reported questionnaires demonstrated that there was a significant difference between schools. Those receiving the training had lower mean scores in risk-taking attitudes than those who did not receive the training. Regardless of intervention, School 2 (complete infrastructure) takes fewer risks than School 1(incomplete infrastructure). The mean difference between groups was not statistically significant.

Show moreCurrent trends in spacecraft are leading to smaller, more inexpensive options whenever possible. This shift has been primarily pursued for the opportunity to open a new frontier for technologies with a small financial obligation. Limited power, processing, pointing, and communication capabilities are all common issues which must be considered when miniaturizing systems and implementing low-cost components. This thesis addresses some of these concerns by applying two methods, in attitude estimation and control. Additionally, these methods are not restricted to only small, inexpensive satellites, but offer a benefit to large-scale spacecraft as well.First, star cameras are examined for the tendency to generate streaked star images during maneuvers. This issue also comes into play when pointing capabilities and camera hardware quality are low, as is often the case in small, budget-constrained spacecraft. When pointing capabilities are low, small residual velocities can cause movement of the stars in the focal plane during an exposure, causing them to streak across the image. Additionally, if the camera quality is low, longer exposures may be required to gather sufficient light from a star, further contributing to streaking. Rather than improving the pointing or hardware directly, an algorithm is presented to retrieve and utilize the endpoints of streaked stars to provide feedback where traditional methods do not. This allows precise attitude and angular rate estimates to be derived from an image which, with traditional methods, would return large attitude and rate error. Simulation results are presented which demonstrate endpoint error of approximately half a pixel and rate estimates within 2% of the true angular velocity. Three methods are also considered to remove overlapping star streaks and resident space objects from images to improve performance of both attitude and rate estimates. Results from a large-scale Monte Carlo simulation are presented in order to characterize the performance of the method.Additionally, a rapid optimal attitude guidance method is experimentally validated in a ground-based, pico-scale satellite test bed. Fast slewing performance is demonstrated for an incremental step maneuver with low average power consumption. Though the focus of this thesis is primarily on increasing the capabilities of small, inexpensive spacecraft, the methods discussed have the potential to increase the capabilities of current and future large-scale missions as well.

Show moreBiological phenomena found in nature can be learned and customized to obtain innovative engineering solutions. In recent years, biologists found that birds and bats use their mechanoreceptors to sense the airflow information and use this information directly to achieve their agile flight performance. Inspired by this phenomenon, an attitude control system for micro air vehicles using rich amount of airflow sensor information is proposed, designed and tested. The dissertation discusses our research findings on this topic. First, we quantified the errors between the calculated and measured lift and moment profiles using a limited number of micro pressure sensors over a straight wing. Then, we designed a robust pitching controller using 20 micro pressure sensors and tested the closed-loop performance in a simulated environment. Additionally, a straight wing was designed for the pressure sensor based pitching control with twelve pressure sensors, which was then tested in our low-speed wind tunnel. The closed-loop pitching control system can track the commanded angle of attack with a rising time around two seconds and an overshoot around 10%. Third, we extended the idea to the three-axis attitude control scenarios, where both of the pressure and shear stress information are considered in the simulation. Finally, a fault tolerant controller with a guaranteed asymptotically stability is proposed to deal with sensor failures and calculation errors. The results show that the proposed fault tolerant controller is robust, adaptive, and can guarantee an asymptotically stable performance even in case that 50% of the airflow sensors fail in flight.

Show moreThe present study explores how children of Hispanic immigrants (CHIs) perceive life in the U.S., and how they view cultural diversity. Questionnaires were given to 92 non-U.S. born CHIs and one of their non-U.S. born Hispanic immigrant parents (HIPs) who have lived in the U.S. between 1 and 17 years (M yrs = 8.43); their views of the U.S. were assessed along with their acceptance of diversity, acculturative stress, and levels of acculturation. In this study, I found that CHIs generally hold positive views of the lives in the U.S. and also hold favorable views toward cultural diversity. Furthermore, this study hypothesized that HIPs significantly influence their CHIs attitudes toward both the U.S. and toward cultural diversity. Overall, my findings validated the theoretically based expectation that demonstrates the power of parental attitudes on their children's attitudes. A significant correlation was found between HIPs' attitudes toward the U.S. and their children's attitudes, as well as, CHIs' attitudes toward the U.S. correlating significantly with their perceptions of their parents' attitudes toward the U.S. Multiple and stepwise regressions further confirmed the importance of parental attitudes toward their children's attitudes toward the U.S. and their openness to cultural diversity. Findings from this study provide implications for future research.

Show moreCollege students enrolled in an online introductory engineering course are not completing their homework assignments at an acceptable rate which impacts them, the instructor, and the college. This research study employed a quasi-experimental evaluation model to assess the effectiveness of two pedagogical methods designed to positively influence student homework completion rates and student attitudes toward homework. Despite evidence that grading penalties encourage students to submit their homework assignments, such strategies have historically been unsuccessful for the course used in this study. The researcher designed two pedagogical interventions, along with a survey instrument, to measure the impact of the interventions on completion rates and student attitudes toward homework, using a combination of inferential and descriptive statistics. Ideally, the findings of this study would be generalizable to subsequent offerings of the course used in this study, as well as other courses taught by the investigator, and potentially other faculty at the college. Although both interventions did not produce statistically significant results on impacting student homework completion rates, or improve student attitudes toward homework, the results of the study did indicate a positive correlation between student self-assessed knowledge gains attributed to the course and its homework. One intervention did improve homework completion rates, but the results only marginally improved final course grades, which does not fully align with prior research studies. In addition, this study provided the researcher an opportunity to study their own practice and the importance of homework and its effectiveness for student learning.

Show moreWith mass shootings occurring with frightening regularity, research into gun ownership behavior is becoming increasingly important for public policy creation and public safety. While extant research tells us that firearm ownership is woven deep into the historical fabric of American culture, scholarship has yet to fully explore predictors for gun ownership. Employing 2015 Pew Research Center political survey data, this study examines the predictive effects of birth cohort, political ideology, and attitudes towards gun control legislation on gun ownership, with and without controls, using hierarchical binary logistic regression models. The presented models examine three separate cohorts: The Millennials, Generation X, and the Baby Boomers. Findings reveal that Millennials, liberal political ideology, attitudes which stress the importance of controlling, as opposed to protecting, gun ownership are significantly less likely to own a firearm. Furthermore, gender, household income, population density, southern residency, and race were also found to significantly influence gun ownership. Implications, limitations, and recommendations for future research are also discussed. While this research cannot perfectly predict individual gun ownership, it does effectively highlight several important facts to consider. From the fog of media speculation, political grandstanding, and overly simplistic and unwarranted assumptions, the results of this study bring into full view the inherent complexity of American gun ownership.

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 purpose of the current study was to investigate the relationship between first-generation college students' (FGCSs) help-seeking attitudes, as measured by the Attitudes Towards Seeking Professional Psychological Help (-) Short Form (Fischer (&) Farina, 1995); public stigma, as measured by the Perceptions of Stigmatization by Others for Seeking Psychological Help (Vogel, Wade, (&) Ascheman, 2009); personal stigma, as measured by the Self-Stigma of Seeking Help Scale Working (Vogel, Wade, (&) Haake, 2006); social support, as measured by the Multidimensional Scale of Perceived Social Support (Dahlem, Zimet, (&) Walker, 1991); and perceived discrimination, as measured by the revised Everyday Discrimination Scale (Stucky et al., 2011). The researcher further investigated mediating effects of public and personal stigma in the relationships among the constructs. The researcher found statistically significant relationships among the variables for FGCSs and mediating effects of personal and public stigma. Specifically, public stigma mediated the relationship between perceived discrimination and personal stigma and the indirect effect of perceived discrimination on personal stigma via public stigma was statistically significant ((&)#223; = .070, p = .030). Personal stigma also fully mediated the relationship between public stigma and help-seeking attitudes and the indirect effect of public stigma on help-seeking attitudes via personal stigma was statistically significant ((&)#223; = -.231, p (<) .001). Public stigma partially mediated the relationship between social support and personal stigma and the indirect effect of social support on personal stigma via public stigma ((&)#223; = -.089, p = .010) was statistically significant. In addition, both public and personal stigma partially mediated the relationship between social support and help-seeking attitudes. The indirect effect of social support on help-seeking attitudes via both public and personal stigma was statistically significant ((&)#223; = .062, p = .015). The researcher presented discussion of results, limitations of the study, and implications of the findings.
