Immigration And Editorial Page Policy: A Case Study Of The Dallas Morning News, Anthony Ellis Hartzel

Public Affairs Theses - Archive

Newspaper editorial pages play a crucial role in democratic society, serving as forums for informed debate. On major issues such as immigration, many factors are at play when members of an editorial board sit down together to shape the institutional voice of their newspaper. Using the explanatory case study method, the author directly observes editorial board deliberations at the Dallas Morning News, and sheds light on the influences that affect those writers and editors before the paper publishes its formal positions. The thesis finds that many influences exist beyond news judgment. Those influences range from intra-group dynamics and corporate management, …


Micromechanical Analysis Of Yielding For Particulate Filled Composites, Chih-Ta Chen Dec 2006

Micromechanical Analysis Of Yielding For Particulate Filled Composites, Chih-Ta Chen

Material Science and Engineering Theses - Archive

Particulate filled composites are hybrid materials which consist of particulates held together by a matrix. In this thesis, a simulation method to obtain overall failure criterion for particulate filled composites based on the computer software "MATHEMATICA" will be presented. The composite is assumed to fail at the matrix just outside the inclusion. By Self-Consistent Method, the composite can be imaged as an inclusion embedded within effective matrix. The Equivalent Inclusion method is then applied to stimulate the stress field within the inclusion. Stress just outside inclusion can be calculated because interfacial traction force on the boundary of inclusion is continuous. …


School Responses To High-Stakes Testing, Mishuk Anwar Chowdhury Dec 2006

School Responses To High-Stakes Testing, Mishuk Anwar Chowdhury

Economics Theses - Archive

This paper analyzes school's responses to high stakes testing. Using a grade level panel dataset from Texas Assessment of Knowledge and Skills (TAKS) for reading and math tests for 2003 through 2006, to find schools responses to failure. I find that there is a tendency for schools to shift resources from subjects that they pass to subjects that they fail. I classify schools' responses as either substitution responses or scale responses. A school has a substitution response if, when it fails to meet the state's required passing rate threshold for one subject for one cohort of students, it shifts resources …


Risk, Resilience And Relocation: A Life Course Exploration Of Resettlement Experiences Of Public Housing Residents, Jan H. Johnston Dec 2006

Risk, Resilience And Relocation: A Life Course Exploration Of Resettlement Experiences Of Public Housing Residents, Jan H. Johnston

Public Affairs Dissertations - Archive

Spatial deconcentration of poverty has been the organizing framework of federally subsidized housing policy for well over a decade. During that time low-income families living in traditional public housing across the country have been involuntarily relocated. Household relocation into lower poverty middle class, while the underlying mobility goal, has proven difficult for many families. We continue to look for evidence for how and whether these families are able to adapt as they are scattered across urban settings. The research focus was to operationalize the resident's adaptive behavior pertaining to deconcentration of poverty by trait difference, familial/cultural cues and perceived institutional …

Spectroscopic Characterization Of Biliary Tract Tissues In-Vivo To Assist Laparoscopic Cholecystectomy, Sarita Kommera

Bioengineering Theses - Archive

Laparoscopic Cholecystectomy is a surgical method for removal of gallbladder when it is diseased with gall stones. Almost 750,000 people are affected with this disease annually in USA. Gall bladder is removed by placing an incision on the cystic duct. This duct is totally embedded in fat (which is a few mm thick) in most of the cases and it becomes a huge problem decreasing the visual capability of the surgeon to distinctly locate the duct. Near Infrared Spectroscopy (NIRS) can solve the fuzziness as it penetrates in a few mm thick tissues. NIRS is one of the simplest techniques …

Novel Intraocular Drug Delivery System For The Prevention Of Posterior Capsule Opacification, Brett Thomes Dec 2006

Novel Intraocular Drug Delivery System For The Prevention Of Posterior Capsule Opacification, Brett Thomes

Bioengineering Dissertations - Archive

Posterior capsule opacification (PCO) is a major complication associated with the implantation of intraocular lens (IOLs). Evidence suggests that PCO formation is caused by abnormal lens epithelial cell (LEC) migration/proliferation. We hypothesize that pharmacologic agents must target inflammatory cells in addition to LECs to inhibit PCO formation. To successfully target both inflammatory cells and LECs, a novel intraocular drug delivery system (DDS) was developed for implantation in the lens capsular bag. Such a system permits direct delivery of anti-inflammatory and anti-proliferative drugs in the lens capsule for extended periods of time resulting in reduced PCO formation. A lubricious polyurethane coating …


A Comprehensive Study Of The Effects Of Eeg Electrode Arrays On Mri Signal-To-Noise At 3t, Aman Ish Goyal Dec 2006

A Comprehensive Study Of The Effects Of Eeg Electrode Arrays On Mri Signal-To-Noise At 3t, Aman Ish Goyal

Bioengineering Theses - Archive

Simultaneous EEG-fMRI offers much potential for gaining complementary, noninvasive information about brain function. While much effort has been devoted to the compelling problem of removing ballistocardiogram and gradient artifacts from the EEG waveforms, less attention has been paid to the impact that increasing density of electrode arrays has on the MR images. Initial work reporting the effects of EEG caps and electrodes on the MR image has been site specific, using customized EEG equipment that those research groups built in-house. Therefore these results are hard to generalize to other laboratory environments. A monotonic decrease in SNR of the images has …

Is This Her Fault Or Mine?: An Examination Of The Overregulation Of Sexuality In Measure For Measure As An Argument Against Early Modern Anti-Theatricalism, Heidi Nicole Tesch Dec 2006

Is This Her Fault Or Mine?: An Examination Of The Overregulation Of Sexuality In Measure For Measure As An Argument Against Early Modern Anti-Theatricalism, Heidi Nicole Tesch

English Theses - Archive

The early modern anti-theatricalist movement sought to permanently close the playhouses, arguing that theaters breed immorality through their association with prostitution and the female body. This thesis examines how Shakespeare's Measure for Measure reappropriates these symbols in an argument against the anti-theatricalist movement, as the overregulation of sexuality mimics the overregulation of the theater. The first section examines the overregulation of prostitution in early modern society and in the play. The second section looks at the resistance to excessive regulation of female bodies that were portrayed as weak and unable to resist sin. The final section evaluates the theatricality of …

Perception Of Diversity, Niveditha Parthasarathy

Psychology Theses - Archive

Two studies were conducted to examine effects of diversity on perception. The primary purpose of the first study was to see how people perceive diverse groups, how comfortable they are working in such groups, and how attracted they are to diverse groups. Results indicated that people prefer working with groups that represented their ethnicity (race-inclusion) and perceived such groups to be more attractive than groups that did not represent their ethnicity (race-exclusion). Also, White participants were more attracted to diverse groups and more willing to work in diverse groups than Black participants. Most importantly, the preference of race-inclusion pictures to …


Spatial Patterns And Determinants Of Industrial Regional Growth In Mexico, 1993-2003: Implications For Regional Planning And Public Policy, Jesus Antonio Trevino Dec 2006

Spatial Patterns And Determinants Of Industrial Regional Growth In Mexico, 1993-2003: Implications For Regional Planning And Public Policy, Jesus Antonio Trevino

Public Affairs Dissertations - Archive

This research investigates industrial regional growth and its determinants in Mexico from 1993 to 2003. Strategies of local economic development, usually based on industrial promotion, require knowing main determinants of industrial regional growth. The case study shows that there is no variable with a systematically strong effect for all industries which policymakers and planners might directly control. This finding warns us about generic policy designs uncritically based on outcomes from other experiences. Although these results show a complex problem in terms of regional policy, some recommendations for industrial spatial distribution may, however, be derived from this study. For instance, during …
