Description
The purpose of this study was to analyze the impact of a context-based teaching approach (STS) versus a more traditional textbook approach on the attitudes and achievement of community college chemistry students. In studying attitudes toward chemistry within this study, I used a 30-item Likert scale in order to study the importance of chemistry in students' lives, the importance of chemistry, the difficulty of chemistry, interest in chemistry, and the usefulness of chemistry for their future career. Though the STS approach students had higher attitude post scores, there was no significant difference between the STS and textbook students' attitude post scores. It was noted that females had higher postattitude scores in the STS group, while males had higher postattitude scores in the textbook group. With regard to postachievement, I noted that males had higher scores in both groups. A correlation existed between postattitude and postachievement in the STS classroom. In summary, while an association between attitude and achievement was found in the STS classroom, teaching approach or sex was not found to influence attitudes, while sex was also not found to influence achievement. These results, overall, suggest that attitudes are not expected to change on the basis of either teaching approach or gender, and that techniques other than changing the teaching approach would need to be used in order to improve the attitudes of students. Qualitative analysis of an online discussion activity on Energy revealed that STS students were able to apply aspects of chemistry in decision making related to socioscientific issues. Additional analysis of interview and written responses provided insight regarding attitudes toward chemistry, with respect to topics of applicability of chemistry to life, difficulties with chemistry, teaching approach for chemistry, and the intent for enrolling in additional chemistry courses. In addition, the surveys of female students brought out subcategories with regard to emotional and professional characteristics of a good teacher, under the category of characteristics of teaching approach. With respect to the category of course experience, subcategories of useful knowledge to solve real-life problems and knowledge for future career were revealed. The differences between the control group females and STS group females with respect to these characteristics was striking and threw insight into how teacher behavior and teaching approach shape student attitudes to chemistry in case of female students.

Description
The purpose of this study is to explore the knowledge and attitudes about autism spectrum disorders among Hispanics in the Southwest. The study will also examine perceived barriers in obtaining resources and preferences in accessing health care. Participants (N = 169) were surveyed using the Autism Awareness Survey, which was developed specifically for this research. Significant differences were found between individuals with high acculturation and low acculturation in exposure to autism, knowledge about autism, perceived barriers to obtaining resources and health care, and attitudes towards people with autism. Additionally, the findings also suggest that although the surveyed population was knowledgeable about the symptoms associated with autism, less well known is the etiology and course of the disorder. The research underscores the serious need for both Spanish educational resources and Spanish-speaking health care providers to address the needs of Hispanics with regards to autism, especially with individuals with low levels of acculturation.

Description
The purposes of this study were (a) to develop a reliable and valid measure of secondary student attitudes toward band teacher turnover using the Thurstone (1928) equal-appearing interval scale as a model, and (b) to administer this measurement tool to determine attitudes of high school band students toward teacher turnover. This procedure included collecting statements about an imagined teacher turnover from students in the population (N = 216) and having student judges (N = 95) sort the statements into eleven categories based on how positive, neutral, or negative, each statement was perceived. The judging results were then analyzed, and 29 statements were selected for inclusion in the final survey, which was completed by students (N = 521) from 10 randomly selected high schools in Arizona. Student responses were analyzed and compared by the independent variables of gender, grade level, and band teacher turnover experience, to determine if significant differences existed. Results indicated that the overall students' attitudes toward teacher turnover are neutral. One significant difference was found in the slightly positive attitudes of students in the year immediately following a band teacher turnover. This only lasts a year, as students in the second year of a teacher turnover were found to have comparable attitudes to students who have not experienced a new teacher transition. Findings also suggest seniors may have a different perspective than other students toward teacher turnover.

Description
This study explores the relationship between restrictive language policies and dropout influences for language minority students. It furthers understanding of factors related to school attachment and restrictive language policies through an analysis of student's attitudes towards their imposed curriculum. Few studies to date have addressed English language learners' (ELLs') attitudes toward school, especially when schools enforce highly restrictive language policies, and the implications of these student perceptions as related to students' level of attachment to school in general. This study addresses this gap. It investigated middle and high school ELLs' and reclassified (RC) students' attitudes toward school, their aspirations for the future, and the language program in which they are or were recently enrolled within the state of Arizona. Using Erickson's analytic induction method and employing descriptive statistics, t tests, and hierarchical multiple regression, 2,264 students were polled from urban school districts in Arizona. The 85-question survey was comprised of demographic questions and attitude items as measured on a 5-point Likert scale. Results indicate some students are not satisfied with the four-hour block and that many students are aware of the negative implications involvement in the four-hour block can incur. Findings also show that language minority students are not receiving an equal education in regards to their curriculum. More importantly, considering policies and practices of schools as a factor, especially those which are restrictive language policies, is important in better understanding ELL and RC students' attachment to school and the potential impact of these policies on the likelihood of language minority students dropping out of school in the future. Policy implications are discussed.

Description
Urban sustainability is a critical component of sustainable human societies. Urban riparian parks are used here as a case study seeking to understand the social-ecological relationships between the subjective evaluation of ecosystem services and the vision and management of one kind of green infrastructure. This study explored attitudes towards ecosystem services, asking whether 1) the tripartite model is an effective framing to measure attitudes towards ecosystem services; 2) what the attitudes towards ecosystem services are and whether they differ between two types of park space; and 3) what the relationship is between management and the attitudinal assessment of ecosystem services by park users. A questionnaire was administered to 104 urban riparian park users in Phoenix, AZ evaluating their attitudes towards refugia, aesthetics, microclimate and stormwater regulation, and recreational and educational opportunities. The operationalization of the tripartite model was validated and found reliable, but may not be the whole story in determining attitudes towards ecosystem services. All components of attitude were positive, but attitudes were stronger in a habitat rehabilitation area with densely planted native species and low flows, than in a more classic park with mowed lawns and scattered vegetation, a mix of native and non-native species, and open water. Park users were more positive towards refugia, stormwater regulation, recreation, and educational opportunities in the habitat rehabilitation area. On the other hand, microclimate regulation and aesthetic qualities were valued similarly between the two parks. Most attitudes supported management goals, however park users valued stormwater regulation less than managers. Qualitative answers suggest that the quality of human interactions differ between the parks and park users consider both elements of society and the physical environment in their subjective evaluations. These findings reveal that park users highly value ecosystem services and that park design and management mediates social-ecological relationships, which should at least underlie the context of economic discussions of service value. This study supports the provision of ecosystem services through green infrastructure and suggests that an integration of park designs throughout urban areas could provide both necessary services as well as expand the platform for social-ecological interactions.

Juror impartiality is necessary for a fair and just legal system, but is true juror impartiality
realistic? The current study investigated the role of implicit and explicit social-cognitive biases in jurors’ conceptualizations of insanity, and the influence of those biases in juror verdict decisions. It was hypothesized that by analyzing the role of implicit and explicit biases in insanity defense cases, jurors’ attitudes towards those with mental illnesses and attitudes towards the insanity defense would influence jurors’ final verdict decisions. Two hundred and two participants completed an online survey which included a trial vignette incorporating an insanity defense (adapted from Maeder et al., 2016), the Insanity Defense Attitude Scale (Skeem, Louden, & Evans, 2004), Community Attitudes Towards the Mentally Ill Scale (Taylor & Dear, 1981), and an Implicit Association Test (Greenwald et al., 1998). While implicit associations concerning mental illness and dangerousness were significantly related to mock jurors’ verdicts, they no longer were when explicit insanity defense attitudes were added to a more complex model including all measured attitudes and biases. Insanity defense attitudes were significantly related to jurors’ verdicts over and above attitudes about the mentally ill and implicit biases concerning the mentally ill. The potentially biasing impact of jurors’ insanity defense attitudes and the impact of implicit associations about the mentally ill in legal judgments are discussed.

Description
Priced Managed Lanes (MLs) have been increasingly advocated as one of the effective ways to mitigating congestion in recent years. This study explores a new and innovative pricing strategy for MLs called Travel Time Refund (TTR). The proposed TTR provides an additional option to paying drivers that insures their travel time by issuing a refund to the toll cost if they do not reach their destination within specified travel times due to accidents or other unforeseen circumstances. Perceived benefits of TTR include raised public acceptance towards priced MLs, utilization increase of HOV/HOT lanes, overall congestion mitigation, and additional funding for relevant transportation agencies. To gauge travelers’ interests of TTR and to analyse its possible impacts, a stated preference (SP) survey was performed. An exploratory and statistical analysis of the survey responses revealed negative interest towards HOT and TTR option in accordance with common wisdom and previous studies. However, it is found that travelers are less negative about TTR than HOT alone; supporting the idea, that TTR could make HOT facilities more appealing. The impact of travel time reliability and latent variables representing psychological constructs on travelers’ choices in response to this new pricing strategy was also analysed. The results indicate that along with travel time and reliability, the decision maker’s attitudes and the level of comprehension of the concept of HOT and TTR play a significant role in their choice making. While the refund option may be theoretically and analytically feasible, the practical implementation issues cannot be ignored. This study also provides a discussion of the potential implementation considerations that include information provision to connected and non-connected vehicles, distinction between toll-only and refund customers, measurement of actual travel time, refund calculation and processing and safety and human factors issues. As the market availability of Connected and Automated Vehicles (CAVs) is prognosticated by 2020, the potential impact of such technologies on effective demand management, especially on MLs is worth investigating. Simulation analysis was performed to evaluate the system performance of a hypothetical road network at varying market penetration of CAVs. The results indicate that Connected Vehicles (CVs) could potentially encourage and enhance the use of MLs.

Description
Affirmative action is an education policy adopted by higher education institutions in the 1960s, where an applicant’s race is taken into account to some degree when being evaluated for admission to a college or university. The practice of affirmative action, or race conscious-admissions, has been repeatedly challenged in the legal system and remains a controversial and polarizing topic amongst the general public, campus leaders, and policy makers. Despite a vast amount of research on the effects of affirmative action policies on student and institutional behaviors and outcomes, such as college applications and enrollments, considerably less research has examined students’ attitudes towards race-conscious admissions policies. Even less research has focused on students in academic disciplines, especially STEM or engineering. Likewise, there is a paucity of research that explores students’ perceptions and knowledge of how affirmative action is implemented in practice. To address these gaps, this study investigates undergraduate engineering students’ knowledge of and attitudes towards affirmative action admissions policies in higher education. The Student Attitudes Towards Admissions Policies Survey (SATAPS) was designed to assess students’ knowledge of and attitudes regarding affirmative action practices in higher education admissions. This survey was administered to undergraduate engineering students and a comparison group of education students at 42 colleges/universities in the United States. Data were analyzed utilizing confirmatory factor analysis and hierarchical regression. Results demonstrated that students have low levels of knowledge about affirmative action, and have misconceptions about how the policy functions in practice. There was no difference in engineering and education students’ level of support for affirmative action; however, underrepresented minority students in engineering were more supportive of affirmative action. Results also indicated that students’ beliefs and values were the strongest predictors of attitude towards affirmative action, so much so that this negated the significance of demographic and personal characteristics, which was observed in the majority of previous studies. Results highlight a complicated relationship between demographic characteristics, personal variables, knowledge, institutional context, beliefs/values, and attitude towards affirmative action admissions policies in higher education.

Description
Although recent research has suggested that motivations such as disease avoidance and self-protection are associated with increased social conservatism, less is known about the impact of other fundamental motivations on political attitudes. This is particularly important given that the currently studied motivations do not consistently push around economic attitudes, which are an important determinant of voting. The current study investigated the impact of a different motivation, status desire, on both economic and social attitudes in a sample of undergraduate students at a large southwestern university. Participants first reported their overall, economic, and social ideology one month before participating in a lab study. Then, in the lab, they were presented either with a vignette designed to elicit status desire, or a closely matched control, before responding to a series of items about economic and social political attitudes. It was predicted that economic conservatives and liberals in the status desire condition would report more economically conservative attitudes relative to their counterparts in the control condition. By contrast, it was predicted that social conservatives in the status desire condition would report more socially conservative attitudes, whereas social liberals in the status desire condition would report more socially liberal attitudes, relative to their counterparts in the control condition. However, the use of hierarchical linear regressions showed no significant effects of motive activation condition, or interactions of motive activation condition with relevant pre-screen political ideology, in predicting either economic or social political attitudes. Implications of these results for future research are discussed.

Description
The purpose of this study is to learn about registered nurses' thoughts and experiences about the use of music and music therapy in the nursing field and whether or not nurses believe that there is supporting evidence practicing music therapy. Through an online survey administered to a local chapter of Sigma Theta Tau International Nursing Honors Society via SurveyMonkey, the study will 1) Assess the awareness and knowledge that registered nurses have regarding the use of music in the medical field. 2) Understand bedside nurses' willingness to use music as a complementary medicine in their own practices. 3) Ascertain where and how bedside nurses get knowledge about the use of music in the medical field. 4) Determine what constraints or barriers may influence bedside nurses' utilization of music in their practice. 5) The study will also examine the extent to which bedside nurses have had experience with observing music therapy or have utilized music therapists in their own practice.
