The Effects Of Preattention In An Online Advertising Context: A Neuroscience Perspective, Milica Milosavljevic

Electronic Theses and Dissertations 2000 - 2009

Consumers are exposed to thousands of marketing messages every day. In such a cluttered environment, gaining consumers· attention becomes an increasingly important business objective. This study expands the concept of attention from a simple view of attention as se lection of stimuli to a more elaborate two step process consisting of (I) preattention and (2) focal attention. The focus of this research is on preattention, which is determined by physical characteristics of objects in a visual scene. This study also i1Pproves the measurement ofpreattention by surveying the neuroscience literature and using a computational model to measure preattention. This improved measure …

The Florida Comprehensive Assessment Test (Fcat) And The Predictive Utility Of The Psat For Fcat Preparedness, Bernadine E Dorantes Beard Jan 2007

The Florida Comprehensive Assessment Test (Fcat) And The Predictive Utility Of The Psat For Fcat Preparedness, Bernadine E Dorantes Beard

Electronic Theses and Dissertations 2000 - 2009

In the years since the establishment of the Florida Comprehensive Assessment test (FCAT) in 1998, the Florida public school districts have had little standardized, diagnostic data to assist in preparation for the FCA T. The FCAT serves as a high-stakes assessment for students as a graduation requirement, and it serves as a high-stakes assessment for school and district accountability for the Florida A++ Plan, and for national accountability within No Child Left Behind Act, 2001. A quantitative study was conducted to determine if the College Board's Preliminary Scholastic Achievement Test, PSAT/NMSQT®, could be used to predict scores on the FCAT. …

The Epidemiology Of Spina Bifida In Ireland: An Anthropological Approach, Kathryn A. O'Donnell Jan 2007

The Epidemiology Of Spina Bifida In Ireland: An Anthropological Approach, Kathryn A. O'Donnell

Electronic Theses and Dissertations 2000 - 2009

A sample of 97 human skeletal remains from Ireland were examined to investigate the etiology of spina bifida, a form of neural tube defect. It is unclear whether the disease results from environmental or genetic causes. Collections of human remains from three sites dated to nineteenth century were studied in an attempt to identify the period during which the prehistoric rates of spina bifida rose to modern levels. In these collections, nineteenth century spina bifida rates were higher than either prehistoric or modern rates. Thus, nineteenth century Ireland experienced peak rates of spina bifida. Nutrition in modern day Ireland has …

The Inactive Self: Mental Representation Of Dormant Social Roles, Ryan M. Moyer Jan 2007

The Inactive Self: Mental Representation Of Dormant Social Roles, Ryan M. Moyer

Electronic Theses and Dissertations 2000 - 2009

A significant portion of the self is constructed from our actions and the roles to which they correspond. Although many of our social roles are enacted regularly, some may lay dormant, yet still influence one's self-concept. We propose that there are systematic differences in mental representation between these inactive roles and more active roles. Specifically, inactive roles should be more likely to be construed in high-level terms, while active roles should be more likely to be construed in lowlevel terms. Experiment 1 found that for inactive roles, participants displayed an implicit construal preference for the high-level aspects of the role. …

The Impact Of A Museum-Based Science Methods Course On Early Childhood/Elementary Pre-Service Teachers' Self-Efficacy And Ability To Develop Curriculum Using A Constructivist Approach, Chelneca Kegley Templeton Jan 2007

The Impact Of A Museum-Based Science Methods Course On Early Childhood/Elementary Pre-Service Teachers' Self-Efficacy And Ability To Develop Curriculum Using A Constructivist Approach, Chelneca Kegley Templeton

Electronic Theses and Dissertations 2000 - 2009

The focus of this study was to discover what impact a museum-based science methods course would have on 14 early childhood/elementary pre-service teachers' selfefficacy and ability to develop curriculum using a constructivist approach. Data were gathered using the STEBI-B, modified by Bleicher (2004). A paired-samples t test indicated there was significant change in the pre-service teachers ' self-efficacy pre-and post-museum course participation. The investigation also analyzed student-created learning centers intended for use in the students' future classrooms. Students created two learning centers, one before interaction with exhibits in the museum and one at the end of the course. At the …

The Lived Experience Of Male Nurses Who Have Successfully Rehabilitated From Chemical Dependency Through The State Of Florida's Intervention Project For Nurses, Patricia Welch Dittman Jan 2007

The Lived Experience Of Male Nurses Who Have Successfully Rehabilitated From Chemical Dependency Through The State Of Florida's Intervention Project For Nurses, Patricia Welch Dittman

Electronic Theses and Dissertations 2000 - 2009

This dissertation reviews the multifaceted dimensions of male nurses in recovery from chemical dependency in the State of Florida's Intervention Project for Nurses Rehabilitation Program. These dimensions are not linear and fluctuation of the degree of intensity is individualized to the lived experience of the nurse. The purpose of this qualitative, phenomenological research study was to understand the lived experience of male nurses who have successfully completed the rehabilitation phase and to determine themes that influenced their vulnerability to professional impairment. The study identified two overarching themes of person and profession. The major theme of person had three sub-themes of …

Carbohydrate Recognition Of Bi-Pyridine Bridged Peptide Receptor, Claudia A. Johnson Jan 2007

Carbohydrate Recognition Of Bi-Pyridine Bridged Peptide Receptor, Claudia A. Johnson

Electronic Theses and Dissertations 2000 - 2009

A novel carbohydrate receptor based on the structure of the antibiotic polymxin B was synthesized. The receptor was a cyclic heptapeptide. which was bridged using 2, 2'-bi pyridine-5,5"- dicarboxylic acid. The association constants of the receptor and a variety of sugars were determined using UV /Vis and fluorescence spectroscopy and observed log K0 values are in the range from 3 .8 to 4.1 for the pentoses, logKa 3.3 to 3.8 for the hexoxes and 0 to 2.9 logKa values from 0-2.9 for disaccharides and logKa of2.6 to 3.11 for the charged sugars. We demonstrated that polymixin based receptors are capable …

Building Cosmopolitical Solidarity From The Antigone: A Return To The Chorus, Rebecca L. Mccarthy Jan 2007

Building Cosmopolitical Solidarity From The Antigone: A Return To The Chorus, Rebecca L. Mccarthy

Electronic Theses and Dissertations 2000 - 2009

“Building Cosmopolitical Solidarity from the Antigone.” takes an in-depth look at how the Antigone by Sophocles has been used by social movements and social/politically concerned playwrights, theorists and activists as either a tool for discursive and performative resistance, or as a way to reinforce status-quo state rule since at least the Enlightenment to present day. I argue that Sophocles’ characters Creon and Antigone are not ideal images for social movements who seek a cosmopolitical democracy. Rather it is to Sophocles’ Chorus and the Watchman that we must turn when proposing democratic cosmopolitanism. Thus, a new communication approach is proposed: a …

Characteristics Affecting Prey Vulnerability And Avian Habitat Selection In The Florida Everglades, Rachael L. Harris Jan 2007

Characteristics Affecting Prey Vulnerability And Avian Habitat Selection In The Florida Everglades, Rachael L. Harris

Electronic Theses and Dissertations 2000 - 2009

The vulnerability of prey to capture plays a fundamental role in determining overall prey availability for wading birds. Structural complexity can act to decrease prey vulnerability and influence foraging habitat selection. To determine how structural complexity can affect habitat selection I conducted a use vs. availability study throughout the Florida Everglades in 2005 and 2006. Results indicated that wading birds chose foraging sites that had less emergent vegetation and a thicker flocculent layer relative to random sites. Submerged vegetation, and the height of emergent vegetation did not affect wading bird site selection. A difference in habitat selection between years was …

Australian youth engage in behaviour that threatens their health and wellbeing. National surveys report that about a third of young Australians have tried an illicit drug. High rates of substance use and risky sexual behaviour among young Australians suggest that effective prevention efforts based on empirical evidence need to be expanded. Church-associated organisations are an untapped resource that could be used to improve the health and welfare of young people. We describe eight evidence-based elements to consider in designing strategies to prevent high-risk behaviour in young people.

The photoproduction of prompt photons, together with an accompanying jet, has been studied in ep collisions at a centre-of-mass energy of 318 GeV with the ZEUS detector at HERA using an integrated luminosity of 77 pb-1. Cross sections were measured for the transverse energy of the photon and the jet larger than 5 and 6 GeV, respectively. The differential γ+jet cross sections were reconstructed as functions of the transverse energy, pseudorapidity and xγobs, the fraction of the incoming photon momentum taken by the photon-jet system. Predictions based on leading-logarithm parton-shower Monte Carlo models and next-to-leading-order (NLO) QCD generally underestimate the …

Novel Concepts For Enhanced Nuclear Thermal Propulsion Using Flow Area Tailoring And A Grooved-Ring Core Design, Julien Michel Apeloig Jan 2007

Novel Concepts For Enhanced Nuclear Thermal Propulsion Using Flow Area Tailoring And A Grooved-Ring Core Design, Julien Michel Apeloig

Theses and Dissertations

The most likely candidate for human missions to Mars and beyond will be spacecraft using Nuclear Thermal Propulsion (NTP). NTP provides for high thrust-to-weight ratio and significantly improved specific impulse over even the best chemical rockets. The improved specific impulse reduces required trip times, thereby minimizing the exposure time of the crew to space radiation. Using the PHOEBUS 2A 5 GW reactor, developed in the 1960’s with a thrust of 1,113 N and a specific impulse of 820 s, as a basis for comparison this thesis focuses on efforts to improve the specific impulse and reactor longevity. Hydrogen is the …

Aesthetic Judgment And Legal Justification, Guyora Binder Jan 2007

Aesthetic Judgment And Legal Justification, Guyora Binder

Journal Articles

Although criticized as illegitimate, literary elements are necessary features of legal argument. In a modern liberal state, law motivates compliance by justifying controversial prescriptions as products of an appropriate process for representing the will of society. Yet because law constructs the will of individual and collective actors in representing them, its representations are necessarily figurative rather than mimetic. In evaluating law's representation of society, citizens of the liberal state are also shaping their own ends. Such self-expressive choices, subjective but non-instrumental, entail aesthetic judgment. Thus the literary elements of rhetorical figuration and aesthetic appeal are fundamental, rather than merely ornamental, …

Religion And Group Rights: Are Churches (Just) Like The Boy Scouts?, Richard W. Garnett Jan 2007

Religion And Group Rights: Are Churches (Just) Like The Boy Scouts?, Richard W. Garnett

Journal Articles

What role do religious communities, groups, and associations play - and, what role should they play - in our thinking and conversations about religious freedom and church-state relations? These and related questions - that is, questions about the rights and responsibilities of religious institutions - are timely, difficult, and important. And yet, they are often neglected.

It is not new to observe that American judicial decisions and public conversations about religious freedom tend to focus on matters of individuals' rights, beliefs, consciences, and practices. The special place, role, and freedoms of groups, associations, and institutions are often overlooked. However, if …

Federalism Doctrines And Abortion Cases: A Response To Professor Fallon, Anthony J. Bellia Jr. Jan 2007

Federalism Doctrines And Abortion Cases: A Response To Professor Fallon, Anthony J. Bellia Jr.

Journal Articles

This Essay is a response to Professor Richard Fallon's article, If Roe Were Overruled: Abortion and the Constitution in a Post-Roe World. In that article, Professor Fallon argues that if the Supreme Court were to overrule Roe v. Wade, courts might well remain in the abortion-umpiring business. This Essay proposes a refinement on that analysis. It argues that in a post-Roe world courts would not necessarily subject questions involving abortion to the same kind of constitutional analysis in which the Court has engaged in Roe and its progeny, that is, balancing a state's interest in protecting life against a pregnant …

The Fourth Amendment Status Of Stored E-Mail: The Law Professors' Brief In Warshak V. United States, Susan Freiwald, Patricia L. Bellia Jan 2007

The Fourth Amendment Status Of Stored E-Mail: The Law Professors' Brief In Warshak V. United States, Susan Freiwald, Patricia L. Bellia

Journal Articles

This paper contains the law professors' brief in the landmark case of Warshak v. United States, the first federal appellate case to recognize a reasonable expectation of privacy in electronic mail stored with an Internet Service Provider (ISP). While the 6th circuit's opinion was subsequently vacated and reheard en banc, the panel decision will remain extremely significant for its requirement that law enforcement agents must generally acquire a warrant before compelling an ISP to disclose its subscriber's stored e-mails. The law professors' brief, co-authored by Susan Freiwald (University of San Francisco) and Patricia L. Bellia (Notre Dame) and signed by …

Suburbs As Exit, Suburbs As Entrance, Nicole Stelle Garnett Jan 2007

Suburbs As Exit, Suburbs As Entrance, Nicole Stelle Garnett

Journal Articles

Most academics assume that suburbanites are exiters who have abandoned central cities. The exit story is a foundational one in the fields of land-use and local-government law: Exiters' historical, social, and economic connections with their center cities are frequently used to justify both growth controls and regional government. The exit story, however, no longer captures the American suburban experience. For a majority of Americans, suburbs have become points of entrance to, not of exit from, urban life. Most suburbanites are enterers - people who were born in, or migrated directly to, suburbs and who have not spent time living in …

Preserving The Peace: The Continuing Ban On War Between States, Mary Ellen O'Connell Jan 2007

Preserving The Peace: The Continuing Ban On War Between States, Mary Ellen O'Connell

Journal Articles

The history of international law is, in large part, about the development of restraints on states' right to resort to force in dealing with external conflicts. Today, states may use force only in self-defense to an armed attack or with Security Council authorization. Even in these cases, states may use force only as a last resort, and then only if doing so will not disproportionately harm civilians, their property, or the natural environment. These rules restricting force are found in treaties (especially the United Nations Charter), customary international law, and the general principles of international law. In other words, the …

A Meta-Analysis Of Political Advertising, William L. Benoit, Glenn M. Leshner, Sumana Chattopadhyay Jan 2007

A Meta-Analysis Of Political Advertising, William L. Benoit, Glenn M. Leshner, Sumana Chattopadhyay

College of Communication Faculty Research and Publications

Political advertising is one of the dominant media for reaching voters. Previous metaanalyses (Allen & Burrell, 2002; Lau, Sigelman, Heldman, & Babbitt, 1999) found little or no net benefit to negative versus positive ads. However, this finding does not reveal whether ads have effects (both or neither could be persuasive). A meta-analysis revealed that political spots increased issue knowledge, influenced perceptions of the candidates’ character, altered attitudes, and affected candidate preference; influenced agenda-setting, and altered vote likelihood (turnout). One moderator variable was detected: The effect size for learning was larger for studies of students than non-students; however, the effect size …

Who Is A Journalist And Why Does It Matter? Disentangling The Legal And Ethical Arguments, Erik Ugland, Jennifer Henderson Jan 2007

Who Is A Journalist And Why Does It Matter? Disentangling The Legal And Ethical Arguments, Erik Ugland, Jennifer Henderson

College of Communication Faculty Research and Publications

The contemporary debate about "who is a journalist" is occurring in two distinct domains: law and professional ethics. Although the debate in these domains is focused on separate problems, participants treat the central question as essentially the same. This article suggests that the debates in law and professional ethics have to be resolved independently and that debate within those domains needs to be more nuanced. In law, it must vary depending on whether the context involves constitutional law, statutory law, or the distribution of informal privileges by government officials. In professional ethics, the debate should not be oriented around a …

Life Without Water : Expression Of Plant Lea Genes By An Anhydrobiotic Arthropod., Steven Hand, Dana Jones, Michael Menze, Trudy Witt

Faculty and Staff Scholarship

Anhydrobiotic animals protect cellular architecture and metabolic machinery in the dry state, yet the molecular repertoire supporting this profound dehydration tolerance is not fully understood. For the desiccation-tolerant crustacean, Artemia franciscana, we report differential expression of two distinct mRNAs encoding for proteins that share sequence similarities and structural features with late-embryogenesis abundant (LEA) proteins originally discovered in plants. Bioinformatic analyses support assignment of the LEA proteins from A. franciscana to group 3. This eucoelomate species is the most highly evolved animal for which LEA gene expression has been reported. It is becoming clear that an ensemble of micromolecules and macromolecules …

Electrical and Computer Engineering Faculty Research & Creative Works

It is crucial for cancer diagnosis and treatment to accurately identify the site of origin of a tumor. with the emergence and rapid advancement of DNA microarray technologies, constructing gene expression profiles for different cancer types has already become a promising means for cancer classification. In addition to research on binary classification such as normal versus tumor samples, which attracts numerous efforts from a variety of disciplines, the discrimination of multiple tumor types is also important. Meanwhile, the selection of genes which are relevant to a certain cancer type not only improves the performance of the classifiers, but also provides …

Non-Pecuniary Interests And The Injudicious Limits Of Appellate Standing In Bankruptcy, S. Todd Brown Jan 2007

Non-Pecuniary Interests And The Injudicious Limits Of Appellate Standing In Bankruptcy, S. Todd Brown

Journal Articles

Standing to appeal bankruptcy court orders today is limited to those with a pecuniary interest. This prudential limitation is based on the person aggrieved requirement of Section 39(c) of the Bankruptcy Act of 1898 - a requirement that was not included in the Bankruptcy Code. This article examines the extensive differences between the Act and the Code, the potential justifications for extending the pecuniary interest test in spite of the omission of the person aggrieved requirement, and the potential ramifications for parties and the integrity of the bankruptcy process. This analysis suggests that standing to appeal bankruptcy orders should be …
