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 …

Association Of Putative Enteroaggregative Escherichia Coli Virulence Genes And Biofilm Production In Isolates From Travelers To Developing Countries, Jamal A Mohamed, David B Huang, Zhi-Dong Jiang, Herbert L Dupont, James P Nataro, Jaime Belkind-Gerson, Pablo C Okhuysen

Faculty, Staff and Student Publications

Enteroaggregative Escherichia coli (EAEC) is an emerging enteric pathogen that causes acute and chronic diarrhea among children, human immunodeficiency virus-infected patients, and travelers to developing regions of the world. The pathogenesis of EAEC strains involves the production of biofilm. In this study, we determined the association between presence of putative EAEC virulence genes and biofilm formation in 57 EAEC isolates (as defined by HEp-2 adherence) from travelers with diarrhea and in 18 EAEC isolates from travelers without diarrhea. Twelve nondiarrheagenic E. coli isolates from healthy travelers were used as controls. Biofilm formation was measured by using a microtiter plate assay …

All In The Family: Atypical Hsp70 Chaperones Are Conserved Modulators Of Hsp70 Activity, Lance Shaner, Kevin A Morano

Faculty, Staff and Student Publications

Divergent relatives of the Hsp70 protein chaperone such as the Hsp110 and Grp170 families have been recognized for some time, yet their biochemical roles remained elusive. Recent work has revealed that these "atypical" Hsp70s exist in stable complexes with classic Hsp70s where they exert a powerful nucleotide-exchange activity that synergizes with Hsp40/DnaJ-type cochaperones to dramatically accelerate Hsp70 nucleotide cycling. This represents a novel evolutionary transition from an independent protein-folding chaperone to what appears to be a dedicated cochaperone. Contributions of the atypical Hsp70s to established cellular roles for Hsp70 now must be deciphered.

Nuclear Localization Of Hbd-1 In Human Keratinocytes, Roger J Bick, Brian J Poindexter, L Maximilian Buja, Carl H Lawyer, Stephen M Milner, Satyanarayan Bhat

Faculty, Staff and Student Publications

OBJECTIVE: Human defensins and cathelicidins are a family of cationic antimicrobial peptides (AMPs), which play multiple roles in both innate and adaptive immune systems. They have direct antimicrobial activity against several microorganisms including burn pathogens. The majority of components of innate and adaptive immunity either express naturally occurring defensins or are otherwise chemoattracted or functionally affected by them. They also enhance adaptive immunity and wound healing and alter antibody production. All mechanisms to explain multiple functions of AMPs are not clearly understood. Prior studies to localize defensins in normal and burned skin using deconvolution fluorescence scanning microscopy indicate localization of …

Mothers Of Soldiers In Wartime: A National News Narrative, Karen L. Slattery, Ana C. Garner

College of Communication Faculty Research and Publications

National news media represent mothers of US combat soldiers in the Iraq War as archetypal good mothers, that is, mothers who continue their maternal work even after their children are deployed. However, not all mothers are depicted as the archetypal patriotic mother, i.e., a good mother who is also stoic and silent about the war and her child's role in it. Mothers of soldiers are portrayed as good mothers who sometimes also voice their attitudes about the war effort. The maternal attitudes ranged from complete support for the war to opposition to the war but support for the soldiers. The …

Does Time Really Slow Down During A Frightening Event?, Chess Stetson, Matthew P Fiesta, David M Eagleman

Faculty, Staff and Student Publications

Observers commonly report that time seems to have moved in slow motion during a life-threatening event. It is unknown whether this is a function of increased time resolution during the event, or instead an illusion of remembering an emotionally salient event. Using a hand-held device to measure speed of visual perception, participants experienced free fall for 31 m before landing safely in a net. We found no evidence of increased temporal resolution, in apparent conflict with the fact that participants retrospectively estimated their own fall to last 36% longer than others' falls. The duration dilation during a frightening event, and …

Gender Curve: An Analysis Of Colleges' Use Of Affirmative Action Policies To Benefit Male Applicants, Debra Franzese

American University Law Review

This comment evaluates the constitutionality of affirmative action policies that benefit male students. Part I sets out background information about potential causes of action and remedies for female students who challenge affirmative action policies that benefit male students. Section A discusses the Equal Protection Clause of the Fourteenth Amendment and the development of the law regarding universities’ use of racial affirmative action policies. Section B discusses potential remedies under Title IX of the Education Amendments of 1972 (“Title IX”) and the similarity between Title IX and Title VI of the Civil Rights Act (“Title VI”). Section C discusses state remedies …

Empty Threats? How Egyptians' Self-Ontology Should Affect The Way We Read Many Texts, Kerry M. Muhlestein

Faculty Publications

Egyptologists have typically divided texts into those that dealt with the divine and those that treated the mundane. This false dichotomy is not one that the Egyptians themselves would have imposed. They saw themselves as mortal beings that interacted with the divine realm and the afterlife. The texts they created reflect this understanding, and thus we are greatly hampered when we insist that the language of a decree, threat formula, or other texts, must refer to either the mundane or the supernatural, but not both. There is ample evidence that the Egyptians often intended specific wording to invoke multiple realms, …

Survey Of The Federal Circuit's Patent Law Decisions In 2006: A New Chapter In The Ongoing Dialogue With The Supreme Court, Gregory A. Castanias, Lawrence D. Rosenberg, Michael S. Fried, Todd R. Geremia

American University Law Review

In 2006, the Federal Circuit decided only one portion of one patent case en banc, and that was done mainly as a procedural matter (the entire case was not argued to an en banc court) in order to reconcile prior conflicting precedent on the issue of induced patent infringement with the recent Supreme Court decision in Metro-Goldwyn-Mayer Studios, Inc. v. Grokster, Ltd., involving induced copyright infringement. But in light of the Supreme Court’s much more muscular review of the Federal Circuit’s patent cases—which may not even reflect the full extent of the Court’s interest in the Federal Circuit’s patent decisions—the …

Genetic Diversity And Low Reproductive Success In Isolated Populations Of Utah Juniper (Juniperus Osteosperma, Cupressaceae), Loreen Allphin, Val J. Anderson, Amy F. Hunt

Faculty Publications

Utah juniper (Juniperus osteosperma) has greatly expanded its historical range in the western United States. Management plans for the species have focused on curtailing its encroachment into sagebrush and grassland communities. These plans often include burning or other methods of elimination. These methods may result in subdivision or fragmentation of existing juniper stands. We initiated a study at Dugway Proving Ground, a U.S. Army facility, to examine the effects of fragmentation on the reproductive success of Utah juniper in isolated populations. We used enzyme electrophoresis to quantify genetic variability in isolated populations. We also determined population reproductive success by examining …

Hiv/Aids Education: What African Youth Say Is Effective, Steven J. Hite, W. James Jacob, Stacey A. Shaw, Donald E. Morisky, Yusuf K. Nsubuga

Faculty Publications

This study on HIV/AIDS-education programs was conducted with the Uganda Ministry of Education and Sports in a national sample of 76 secondary schools in Uganda. Participants included secondary students (N=883) who critiqued their formal and informal school curricula and offered youth perspectives regarding what teaching mediums and programs of HIV/AIDS prevention are most effective. Results indicated that HIV/AIDS education is not taught in their respective school curricula. Students report on informal ways that are helpful in learning about AIDS, recommend changes to their school's curriculum, and report that reactions from various groups in their lives to HIV/AIDS education in their …

A Survey Of Dating And Marriage At Byu, Bruce A. Chadwick, Mindy Judd, Richard J. Mcclendon, Lauren Smith, Brent L. Top

Faculty Publications

A 2001 study of 1,000 young women attending four-year colleges and universities across the United States conducted by Norval Glenn and Elizabeth Marquardt found that “dating” has all but disappeared from American college campuses. Only half of the women reported they had been asked on six or more dates during their entire college career. In fact, one-third of the women had two or fewer dates during the same four years. Instead of dating, college students now “hang out” in mixed groups in a variety of settings including apartments, dormitory rooms, student centers, pizza parlors, coffee shops, and bars. From these …
