Thesis advisor: Henry Braun / There is a broad interest in narrowing achievement gaps among all groups of students and improving education by scientifically sound methods. On October 25, 2006, the United States Department of Education published new regulations allowing single-sex education in public schools whenever schools think it will improve student achievement. Thus far, studies comparing single-sex with coeducational schools have been carried out at the national level mostly in England, Australia and Jamaica, while US' studies were limited to Catholic schools. Few studies reported descriptive statistics or effect sizes and most studies differ in the criteria and statistical controls they use to compare single-sex and coeducation. This dissertation presents models for science achievement and attitudes towards science for 8th -grade students attending either single-sex or coeducation schools in Hong Kong and New Zealand, using the Trends in Mathematics and Science Study (TIMSS) datasets from 1995, 1999, and 2003. To properly account for the nested structure of data, an HLM model was estimated for each sex, for each of the two jurisdictions at three time points, corresponding to the three TIMSS administrations. The within - country results were compared to see if differences between single-sex and coed schools were consistent over time. In addition, this dissertation proposed an approach to examine the sensitivity of the estimated effects of school-type on student outcomes to the presence of unmeasured variables which may introduce hidden selection bias, using a modification of the method proposed by Rosenbaum and Rubin (1983). Based on its conditional distribution with an instrumental variable, chosen based on the review of single-sex literature, the Monte Carlo simulated values of the unobserved variable were used as level-1 predictors in a one-way ANCOVA with random effects. The sensitivity analysis was limited to science achievement of Hong-Kong's girls in TIMSS 2003. Findings show that single-sex education contributed to girls' science performance and attitudes in NZL 1999 and HKG 1999 and 2003, and low sensitivity for school-type contrast. / Thesis (PhD) — Boston College, 2012. / Submitted to: Boston College.

This research investigated the effects of the media on attitudes toward police and fear of crime, while controlling for selected audience trait variables. A self-report questionnaire was administered to 351 students at East Tennessee State University. The survey consisted of demographic and audience trait variables. The survey also contained items that measured the respondants' media consumption. Respondents were asked, for example, which format they typically get news from (e.g., newspaper, television), how often they watch television, and how real they perceive crime related television to be. Multivariate analysis showed that demographic and audience trait variables explained more variance than did media-related variables.

The current study sought to assess the impact of the race, gender, and ethnicity of rape victims on college students’ propensity to assign culpability to victims. Using a sample of college students (n=279) from a mid-sized Southeastern university, respondents were given a set of six different vignettes, varying only by victim characteristics. These vignettes featured alcohol-facilitated sexual assault between acquaintances, a common occurrence in college environments. Respondents were asked to evaluate the culpability of the victim through a blameworthiness scale. Through the incorporation of the Illinois Rape Myth Acceptance Scale, this study also measured the respondents’ propensity to assign blame to female rape victims and to alleviate male perpetrators of any responsibility. Results indicated that adherence to rape myth acceptance was a more significant predictor of blameworthiness than victim or respondent characteristics. This exploratory study was designed to add to the growing body of literature examining attitudes toward acquaintance rape.

Objectives: Breast-feeding rates in rural and southeastern regions of the United States are lower than national rates and Healthy People 2020 targets. The objectives of this study were to understand current breast-feeding knowledge, attitudes, and beliefs among rural southern Appalachian adolescents and to explore whether a high school educational intervention designed to address the five tenets (knowledge, attitudes, intentions, perceived behavioral control, and subjective norms) of the theory of planned behavior may be effective in increasing future rates of breast-feeding in this population. Methods: An educational session including an interactive game was developed and administered to occupational health science students during a single class period in two county high schools. A presurvey and a postsurvey administered 2 weeks after the intervention were completed by students. Pre- and postsurveys were analyzed using paired ttests and Cohen d and potential differences based on sex and grade were explored. Results: Both pre- and postsurveys were completed by 107 students (78%). Knowledge, attitudes about breast-feeding benefits, subjective norms, and intentions significantly improved following the intervention. Baseline knowledge and attitudes about breast-feeding benefits for mothers were low and demonstrated the greatest improvement. Conclusions: Offering breast-feeding education based on the theory of planned behavior in a single high school class session was effective in improving student knowledge, attitudes, and beliefs about breast-feeding and intention to breast-feed.

The primary goal of this dissertation was to gain a better understanding of individuals’ membership benefits preferences and attitudes toward donation programs in the context of urban zoo settings. The first objective of this dissertation was to provide a background on membership and donation related research in the context of zoos and other relevant organizations. Based on the review of literature, the second objective was to empirically examine, through two independent studies, zoo membership benefit preferences and attitudes toward a donation program. <div><br></div><div>Despite a wealth of knowledge in the literature with respect to zoo visitors, animals, exhibits, and related programs, little research has been conducted on individuals’ preferences for zoo membership benefit packages and attitudes toward donation programs. To fill the gaps in these areas, the first empirical study examined factors that influence current and prospective members’ decision-making when choosing a membership package at an urban zoo. More specifically, the study explored preferences for selected membership program benefits and benefit levels, as well as how these preferences varied among visitors grouped by key segmentation variables. The study findings suggested that price of membership package was the most important factor, followed by the discount on food and beverage and the proportion of membership fees devoted to animal conservation. As expected, the visitors who scored high on place attachment to the zoo were more supportive of the zoo and less sensitive to variations in the specific options included in the zoo’s membership package. <br></div><div><br></div><div>In the second study, attitudes toward a donation program at an urban zoo were examined. In particular, this study investigated subgroups’ differences segmented by their membership status, place attachment levels, and attitudinal positions. A two-dimensional/bivariate attitude approach was employed to explore potential differences among attitudinal position groups. The study findings indicated while most respondents held positive attitudes toward the donation program, zoo members and nonmembers did not differ significantly. The likelihood of joining the donation program was significantly higher for those in the positive dominant attitude group compared to those in the negative dominant and equally ambivalent groups. Additionally, a qualitative analysis revealed that many respondents were concerned about the cost or affordability of the donation program; and perceived the benefits of the program as a poor value.<br></div><div><br></div><div>Collectively, the two empirical studies provide useful insight for managers and professionals charged with developing membership and donation programs in zoological parks and other relevant organizations. The study results also suggest a number of potentially productive directions for future research in these areas.<br></div><div><br></div>

Visual implicit propositioning suggests that exemplars can activate stereotypes regarding social group members, affecting how individuals may perceive issues presented in a news format. This experiment sought to test the main tenet of visual implicit propositioning by examining how gay exemplars affect social estimate perceptions associated with the mortgage crisis and support for programs that would help homeowners refinance their mortgages. One hundred and ninety heterosexual college students read a news story featuring recent the mortgage crisis with a gay male couple, a heterosexual couple or a house and reported their perceptions related to various social groups. Gay exemplars did not affect social estimate perceptions, but did affect support for programs that would help homeowners refinance their homes. Attitudes towards gay males was examined as a moderating variable, however, this study did not find that these attitudes moderated the relationship between the exemplar presented and social estimates or support for programs.

Street harassment, the sexual harassment by strangers in public places, is a common experience shared by many women and has been linked with other forms of sexual victimization. The negative impact of street harassment, such as fear and behavior to avoid being harassed, points to the need for preventing the behavior. This study sought to determine whether the documentary-style film War Zone may be effective in impacting men’s attitudes toward street harassment, and whether the effectiveness of the film would depend on men’s hostility toward women and level of peer acceptance for street harassment. Findings do not support the effectiveness of War Zone as a component of street harassment prevention. However, the data does suggest that endorsement of hostile attitudes toward women predicts a lack of empathy, and that endorsement of hostile attitudes toward women, a lack of empathy, and peer acceptance of street harassment predict acceptance of street harassment.

The purpose of this study is to explore the relationship between the attitudes toward women of female managers, the quality of leader-member exchange between female managers and their female subordinates, and female managers¡¦queen bee behavior which female subordinates perceived. Moreover, this study examined seven related moderator variables within the relationship between the attitudes toward women of female managers and their queen bee behavior female subordinates perceived. We collected 140 matched questionnaires from female managers and one of their random female subordinates as a complete set in various industries, and 129 of 140 sets are valid. Our results showed that the attitudes toward women of female managers had a significant positive relationship with queen bee behavior female subordinates perceived, which means the more traditional attitudes toward women female managers hold, the higher degree queen bee behavior their female subordinates perceived. Besides, we found a significant negative relationship between the quality of leader-member exchange between female managers and their female subordinates, and queen bee behavior female subordinates perceived, which indicates the lower the exchange quality between female managers and their female subordinates, the higher degree queen bee behavior female subordinates perceived. And we also found that marital status of female managers and the female portion in their departments moderated the relationship between the attitudes toward women of female managers and queen bee behavior female subordinates perceived. Further practical implications and suggestions are also discussed in this study.

The purpose of this study was to explore junior high school students¡¦ attitudes toward learning English and achievement in learning English, and analyzed the significant differences between student came from different backgrounds, students¡¦ attitudes toward learning English and achievement in learning English. Stratified sampling was conducted to recruit 470 junior high school students who are 2nd graders in Kaohsiung city. All participants completed the questionnaire of ¡§attitudes toward learning English scale¡¨ which was developed by the investigator. Descriptive statistics, independent t-tests, one-way ANOVA, spearmann¡¦s rank correlation test and chi-square test assessed the similarities and differences among groups. The initial findings were as follows: 1.The attitudes toward learning English of junior high school students are good. 2.Huge gaps are found in low and high achievers¡¦ achievement in learning English. 3.Female students¡¦ attitudes toward learning English are significantly higher than male students¡¦. 4.Students with longer time spending in learning English showed significantly higher scores in attitudes toward learning English scale than those who spent fewer time in learning English. 5.Students came from families with higher educated parents presented significantly higher scores in attitudes toward learning English scale than those who came from families with lower educated parents. 6.Students who received more support from family members presented significantly higher scores in attitudes toward learning English scale than those who were lack of support from family members. 7.Number of years of learning English showed significant effects on the attitudes toward learning English scale. The more time students spent in learning English, the better achievement they accomplish. 8.Students who attained private English tutoring presented significantly higher scores in attitudes toward learning English scale than those who only learned English from formal school education. 9.There were significantly positive correlations among students¡¦ attitudes toward learning English and achievement in learning English. Results hopefully contribute to further researches in student¡¦s attitudes toward learning English and achievement in learning English. Suggestions are provided to parents as well as school teachers.

This thesis investigated attitudes toward sexual harassment (SH) and relationship between these attitudes, ambivalent sexism and ambivalence toward men. 311 Middle East Technical University students with a mean age of 22 participated in this study. Attitudes toward SH was measured by Sexual Harassment Attitude Scale (SHAS), which has three subfactors / accepting SH as a result of provocative behaviors of women, accepting SH as normal flirtations between men and women, and endorsement of SH as a trivial matter, respectively. Ambivalent sexism was measured by Ambivalent Sexism Inventory (ASI) and ambivalence toward men was measured by Ambivalence toward Men Inventory (AMI). Sequential regression analysis revealed that gender, Hostile Sexism (HS) and Benevolence toward Men (BM) predicted acceptance of SH as provocative behaviors of women. Additional analysis demonstrated that gender, BM, Benevolent Sexism (BS) and age predicted acceptance of SH as normal flirtations. Finally, BS, gender, economy class and department were significantly predicting endorsement of SH as a social problem. Main contributions of this thesis were investigating (1) attitudes toward sexual harassment and its relationship with ambivalent sexist attitudes toward not only to women but also to men and (2) effects of gender, and some other demographic variables such as age, department and economy class on predicting attitudes toward SH.
