Lopez, Jerry, Han, Deguang, University of Central Florida
- Abstract / Description

Since their discovery in the early 1950's, frames have emerged as an important tool in areas such as signal processing, image processing, data compression and sampling theory, just to name a few. Our purpose of this dissertation is to investigate dual frames and the ability to find dual frames which are optimal when coping with the problem of erasures in data transmission. In addition, we study a special class of frames which exhibit algebraic structure, discrete Gabor frames. Much work...
Show moreSince their discovery in the early 1950's, frames have emerged as an important tool in areas such as signal processing, image processing, data compression and sampling theory, just to name a few. Our purpose of this dissertation is to investigate dual frames and the ability to find dual frames which are optimal when coping with the problem of erasures in data transmission. In addition, we study a special class of frames which exhibit algebraic structure, discrete Gabor frames. Much work has been done in the study of discrete Gabor frames in $\mathbb^n$, but very little is known about the $\ell^2(\mathbb)$ case or the $\ell^2(\mathbb^d)$ case. We establish some basic Gabor frame theory for $\ell^2(\mathbb)$ and then generalize to the $\ell^2(\mathbb^d)$ case.

Show moreThis thesis illuminates the experiences, motives, and framing process of a cohort of homebirthing women in Tucson, Arizona who embody the collective action frames of the national homebirth movement. A model of birth frame construction, alignment and adoption is presented that expands current theory on social movement framing processes, cognitive liberation, and life politics in health and self-help related movements. The study explores the evolution of homebirth midwifery nationally and locally. It articulates the main collective action frames that argue against standard maternity care and presents the alternatives proffered by the homebirth movement. It presents micro-level experiences of movement pioneers, macro-articulations of movement leaders, respondent's micro-level birth model framing processes; and how "life politics" have changed birth culture in America. Written materials augmented data obtained from in-depth interviews with (n=38) respondents who homebirthed in Tucson between 1970 and 2000. Content analysis was utilized and grounded theory was employed.

Presidents of Community Colleges and the administrators who reported directly to them were the subjects for this study based on the Four Frame Leadership Theory of Bolman and Deal (1990b). The Leadership Orientation (Self) Survey (LOS) was mailed to 169 community college presidents and administrators in the presidents' direct report teams. The final usable response rate of 69.82% to the survey fell within the acceptable range for education as defined by Boser and Green (1997). In addition...
Show morePresidents of Community Colleges and the administrators who reported directly to them were the subjects for this study based on the Four Frame Leadership Theory of Bolman and Deal (1990b). The Leadership Orientation (Self) Survey (LOS) was mailed to 169 community college presidents and administrators in the presidents' direct report teams. The final usable response rate of 69.82% to the survey fell within the acceptable range for education as defined by Boser and Green (1997). In addition, the subjects were asked to write about the most difficult challenge they had faced in their current position and how they handled that challenge. The purpose of this study was to determine (a) the usage of leadership frames from both groups; presidents and their administrative teams, (b) if gender or years of experience in their current positions were factors in leadership frame usage in each group, and (c) if there was a relationship between a president's frame usage and the frame usage of the members of the direct report team. The major findings were: 1. The presidents and administrators displayed the highest mean scores for the human resource frame with the mean scores of the three remaining frames (structural, political, and symbolic) clustering as a second unit of responses. In the narrative segment of the survey, the most frequently rated central theme among the presidents and the direct reports was the political frame. 2. The results from statistical analysis of the responses from both groups (presidents and the administrators who directly reported to them) did not show any statistically significant difference among frame use based on gender or number of years of experience in their positions. 3. The correlation coefficients did not indicate that there was a relationship in either direction regarding leadership style between the two groups (presidents and administrators). A phenomenological analysis of the scenario statements from these two groups indicated that presidents who used the political frame as a central theme tended to have administrators who also used the political frame as one or as a pair of central themes. Presidents who used the symbolic frame as a central theme tended to have administrators who used all four frames as central themes in their narratives. 4. A fourth finding was the discrepancy in the ability of the leaders to use multiple frames as demonstrated in the results from the quantitative and qualitative findings. The quantitative data suggested that these leaders were practicing the techniques of multi-framing more than one-half of the time. Contrary to this finding, the qualitative data showed that 5 of 30 scenario statements showed paired frames being used as central frames. 5. One additional finding based on the qualitative statements by presidents and their administrators revealed much thought and intentional practice in the leaders' ability to build teams.

Show moreGay/Straight Alliances aimed at providing sexual minority youth and their allies with support, social events, and activism and education opportunities have proliferated in high schools in the United States over the past two decades. This study employs a qualitative, grounded theory approach to examine how sexual minority youth and their allies navigate gender, sexuality, and social movement participation. A year and a half of observation and 16 semi-structured individual interviews were conducted with Gay/Straight Alliance members in a high school setting in the southeastern United States. The study reveals that, through the lens of frame analysis, the G/SA is analogous to larger and more organized social movement organizations. The findings also suggest members often struggle and engage with issues surrounding sexuality, including its origins, coming out as a process, and judgments and evaluations surrounding sex and desire. Additionally, the findings address elements of gender conformity and non-conformity.

Show moreThis study investigated the most common frames used in news coverage of the Church of Scientology from 2009 to 2013. Using textual analysis, with framing and public relations theories as lenses, this study examined recent news coverage (-) both print and television (-) to identify frames used, and the potential public relations crises the Church is currently facing due to this media exposure. Analysis showed three major frames used during coverage, along with their corresponding sub-frames, which highlight certain aspects of the frame: Culture of Abuse (Imprisonment, Controlling, Family Disconnection, Exploitation of Children, Violence, and Financial Abuse), The Information Paradox (Conflicting Information, Simple Misunderstanding, and Non-Traditional Approach), and Leadership Issues (The Problem Lies with Leadership, Celebrity Obsession). Also uncovered were three potential public relations crises: The Mistreatment of Church Members, The Misuse of Funds, and Bad Communication Strategy. The research showed a strong strategic preference of the Church to use legal tactics or denial strategies when dealing with crises. A review of public relations theory suggests that the Church use a more open approach and also incorporate mortification strategies to accept blame and repair their damaged image.

The results showed that coverage of Iran in the elite American print media as it related to terror was higher in the period after Khomeini came to power and also in the period after AhmadinejadÂÂ's election than it was in the period immediately preceding their respective ascensions. The results also showed that there was more coverage of Iran as it related to terror in the year surrounding AhmadinejadÂÂ's election than there was during the year surrounding Ayatollah KhomeiniÂÂ's rise to power in Iran.

Show moreThere are many possible sources for youth to become educated about sexuality and reproduction, however the media are cited as particularly powerful and prominent sources of information (Jaworski, 2009). Particularly in an era in which abstinence-only messaging dominates sex education, media become a source to which young people turn and where they receive much of their sex-based messaging. Due to backlash over problematic content that perpetuates gender stereotypes and relays harmful messages about sex and sexuality, some magazines, including Teen Vogue, have attempted to shift towards more feminist-minded content (Keller, 2011, Milkie, 2002). This study is a qualitative critical feminist media analysis that examined the framing of sex, sexuality, and reproduction content in a sample of 60 Teen Vogue articles, an online publication that targets adolescents and young adults. The analysis revealed that overall, articles conveyed positive representations of sexuality, advocating for affirming and evidence-based sex education, self-empowerment through knowledge, and comprehensive reproductive healthcare for all. However, contradictory frames of sex stigmatization and a reproductive rights framework that advocates primarily for abortion rights were still highly prevalent in the data. Considering media is a significant component of the sexual socialization of youth, Sex Positive framing of sexuality which prioritizes pleasure, healthy relationships and sexual dynamics, and inclusive and affirmative sex education helps to create new narratives in media concerning how sex is viewed. These messages may have positive impacts by creating healthier sexual scripts and becoming dominant narratives in the future. However, articles in the data also utilized fear-mongering tactics that are notoriously used in abstinence-only sex education. These messages aid in further stigmatizing young people not only for having sex but also for not being informed of the potential associated risks, creating a harmful paradox that may counteract the goals of sexual health and sex positivity. Additionally, reproductive rights and reproductive justice messaging and the presentation of policy updates relevant to young readers has the potential to inform and socialize young people to be better informed about sex and sexuality, which may, in turn, lead to greater sexual empowerment. Such messaging may also empower youth activists in a time of political turmoil, connecting teen readers to what is going on around them, and providing concrete actions they can take to create political change. ?

Show moreObesity is one of the major public health issues in the United States, often regarded as part of a global crisis. Companies invest billions of dollars each year towards television advertising campaigns aimed at convincing audiences how their ground-breaking discovery 'battles the bulge' or somehow offers an increased health benefit. This study examined how advertisers presented health-related claims, including health and nutrient-content claims, in U.S. adult-targeted television food commercials. The claims were compared to FTC, FDA, and USDA laws, regulations, and recommendations. A content analysis of food advertising was conducted of commercials from major and cable network programs broadcast during prime-time in the first quarter of 2009. The majority of claims match current regulations when compared to Federal references. The results show that Nutrient and Wellness claims were the most frequently cited. The type of benefit, Healthy Eating, emerged almost 3 times more than any other benefit type. This is also similar to those results which suggest advertisers' intentions were to promote overall wellness in their content delivery. As such, the Wellness Approach was identified and conceptualized, leading towards full development of a Wellness Effect theory. Implications and future research opportunities are discussed on both a theoretical and practical level.
