Characterizing The Evolutionary Path(S) To Early Homo, Lauren Schroeder, Charles C. Roseman, James M. Cheverud, Rebecca R. Ackermann

Biology: Faculty Publications and Other Works

Numerous studies suggest that the transition from Australopithecus to Homo was characterized by evolutionary innovation, resulting in the emergence and coexistence of a diversity of forms. However, the evolutionary processes necessary to drive such a transition have not been examined. Here, we apply statistical tests developed from quantitative evolutionary theory to assess whether morphological differences among late australopith and early Homo species in Africa have been shaped by natural selection. Where selection is demonstrated, we identify aspects of morphology that were most likely under selective pressure, and determine the nature (type, rate) of that selection. Results demonstrate that selection must …

Capital Punishment Reforms In Illinois: Comparing The Views Of Police, Prosecutors, And Public Defenders, Robert M. Lombardo, David Olson

Criminal Justice & Criminology: Faculty Publications & Other Works

On 9 March 2011, Governor Patrick Quinn abolished capital punishment in Illinois stating that the state’s system of imposing the death penalty was inherently flawed. Quinn’s announcement followed an eleven-year effort to end the death penalty that began with a 2000 moratorium on executions imposed by then Governor George Ryan. This moratorium was the direct result of the appellate reversal of a series of death-row convictions. Prompted by these reversals, Ryan also created the Governor’s Commission on Capital Punishment to study the use of the death penalty in Illinois. As a result of this effort, comprehensive legislation was enacted to …

Dead-Box Helicase Proteins Disrupt Rna Tertiary Structure Through Helix Capture, Cynthia Pan, Jeffrey P. Potratz, Brian Cannon, Zachary B. Simpson, Jessica L. Ziehr, Pilar Tijerina, Rick Russell

Physics: Faculty Publications and Other Works

DEAD-box helicase proteins accelerate folding and rearrangements of highly structured RNAs and RNA–protein complexes (RNPs) in many essential cellular processes. Although DEAD-box proteins have been shown to use ATP to unwind short RNA helices, it is not known how they disrupt RNA tertiary structure. Here, we use single molecule fluorescence to show that the DEAD-box protein CYT-19 disrupts tertiary structure in a group I intron using a helix capture mechanism. CYT-19 binds to a helix within the structured RNA only after the helix spontaneously loses its tertiary contacts, and then CYT-19 uses ATP to unwind the helix, liberating the product …

How Not To Defend The Liberal Arts, Paul Jay

English: Faculty Publications and Other Works

It's a myth that the sciences have theories and methods and the humanities don't, and it's a mistake to scapegoat theory and professionalization for the current plight of the humanities and liberal arts.

Youth Gangs: An Overview Of Key Findings And Directions For The Future, Terrance J. Taylor, J. Michael Vecchio

Criminal Justice & Criminology: Faculty Publications & Other Works

Youth gangs have received considerable attention for many decades. Undoubtedly, their disproportionate involvement in violence is one main reason for this attention. While gang members spend most of their lives engaging in the same types of behaviors as other youth (sleeping, eating, playing video games, going to school), they are also much more likely than non-gang members to be involved in violence and other criminal activity. Indeed, scholars have often highlighted the functional nature of violence as it pertains to gangs.

Gangs come in a variety of forms: prison gangs, outlaw motorcycle gangs, extremist groups, and drug trafficking organizations, among …

Epigenetics And Social Context: Implications For Disparity In Cardiovascular Disease, Karen L. Saban, Herbert L. Matthews, Holli A. Devon, Linda W. Janusek

Nursing: School of Nursing Faculty Publications and Other Works

BACKGROUND:

Although it is well established that African Americans (AA) experience greater social stressors than non-Hispanic Whites (NHW), the extent to which early life adversity and cumulative social stressors such as perceived discrimination, neighborhood violence, subjective social status, and socioeconomic status contribute to disparity in coronary heart disease (CHD) and stroke between AA and NHW are not well understood.

PURPOSE:

The purpose of this paper is to propose a conceptual model based upon McEwen’s Allostatic Load Model suggesting how the relationships among social context, early life adversity, psychological stress, inflammation, adaptation, and epigenetic signature may contribute to the development of …

How Secular Should Democracy Be? A Cross-Disciplinary Study Of Catholicism And Islam In Promoting Public Reason, David Ingram, David Ingram

Philosophy: Faculty Publications and Other Works

I argue that the same factors (strategic and principled) that motivated Catholicism to champion liberal democracy are the same that motivate 21^st Century Islam to do the same. I defend this claim by linking political liberalism to democratic secularism. Distinguishing institutional, political, and epistemic dimensions of democratic secularism, I show that moderate forms of political and epistemic secularism are most conducive to fostering the kind of public reasoning essential to democratic legitimacy. This demonstration draws upon the ambivalent impact of Indonesia’s Islamic parties in advancing universal social justice aims as against more sectarian policies.

Teaching, Learning, And Leading With Schools And Communities: One Urban University Re-Envisions Teacher Preparation For The Next Generation, Ann Marie Ryan, David C. Ensminger, Amy J. Heineke, Adam S. Kennedy, David P. Prasse, Lara K. Smetana

Education: School of Education Faculty Publications and Other Works

Ultimately, the national goals of improving learning outcomes for all students and reducing, if not eliminating, the achievement gap require a teaching corps that brings knowledge and professional competencies to have positive impacts on diverse learners in diverse settings (Gándara & Maxwell-Jolly, 2006). As central actors in schools, teachers have the greatest impact on student achievement (Cochran-Smith & Fries, 2005). Nevertheless, due to varied challenges of preparing high-quality teachers within the context of traditional schools of education, preparation programs have yet to consistently and comprehensively produce teachers who accomplish these outcomes (Ball & Forzani, 2009; Larabee, 2004, 2010). While substantive …

Molecular Interactions With Ice: Molecular Embedding, Adsorption, Detection, And Release, K D. Gibson, Grant G. Langlois, Wenxin Li, Daniel Killelea, S J. Sibener

Chemistry: Faculty Publications and Other Works

The interaction of atomic and molecular species with water and ice is of fundamental importance for chemistry. In a previous series of publications, we demonstrated that translational energy activates the embedding of Xe and Kr atoms in the near surface region of ice surfaces. In this paper, we show that inert molecular species may be absorbed in a similar fashion.We also revisit Xe embedding, and further probe the nature of the absorption into the selvedge. CF4 molecules with high translational energies (≥3 eV) were observed to embed in amorphous solid water. Just as with Xe, the initial adsorption rate is …

The Land Of Opportunity Doesn't Apply To Everyone: The Immigrant Experience, Race, And Asian American Career Choices, Oiyan Poon

Education: School of Education Faculty Publications and Other Works

Despite their popular portrayal as high achieving and structurally incorporated, race continues to shape the career choices of Asian American college students. As second-generation Americans, Asian Americans negotiate a constellation of factors when deciding their career choices, most notably, pressures from immigrant parents, awareness of labor market discrimination, fear of being tokenized in particular occupational fields, and influences from peer networks. These findings help elucidate how race and the social context of immigrant adaptation can affect the occupational trajectories of Asian Americans and other children of immigrants in the United States, regardless of their educational achievement and socioeconomic status.

Understanding The Yelp Review Filter: An Exploratory Study, David Kamerer

School of Communication: Faculty Publications and Other Works

Reviews on Yelp.com can be an important factor in driving customers to a business. However, many business owners have expressed concern with Yelp’s review filtering system, which was created to flag low–quality or fake reviews. This study performs a content analysis of a subset of Yelp restaurant and religious organization reviews, visible and filtered, exploring signals from the reviews or the reviewers that might explain the filtering process. The study finds that factors intrinsic to the review itself are not related to filtering, but factors related to the reviewer are strong predictors. The Yelp system is much more likely to …

Primary Seronegative But Molecularly Evident Hepadnaviral Infection Engages Liver And Induces Hepatocarcinoma In The Woodchuck Model Of Hepatitis B, Ranjit Chauhan

School of Medicine

Hepadnavirus at very low doses establishes in woodchucks asymptomatic, serologically undetectable but molecularly evident persistent infection. This primary occult infection (POI) preferentially engages the immune system and initiates virus-specific T cell response in the absence of antiviral antibody induction. The current study aimed to determine whether POI with time may culminate in serologically identifiable infection and hepatitis, and what are, if any, its pathological consequences. Juvenile woodchucks were intravenously injected with inocula containing 10 or 100 virions of woodchuck hepatitis virus (WHV) to induce POI and followed for life or up to 5.5 years thereafter. All 10 animals established molecularly …

Acute Effects Of Tio2 Nanomaterials On The Viability And Taxonomic Composition Of Aquatic Bacterial Communities Assessed Via High-Throughput Screening And Next Generation Sequencing, Binh Chu, Tiezheng Tong, Jean-François Gaillard, Kimberley A. Gray, John J. Kelly

Biology: Faculty Publications and Other Works

The nanotechnology industry is growing rapidly, leading to concerns about the potential ecological consequences of the release of engineered nanomaterials (ENMs) to the environment. One challenge of assessing the ecological risks of ENMs is the incredible diversity of ENMs currently available and the rapid pace at which new ENMs are being developed. High-throughput screening (HTS) is a popular approach to assessing ENM cytotoxicity that offers the opportunity to rapidly test in parallel a wide range of ENMs at multiple concentrations. However, current HTS approaches generally test one cell type at a time, which limits their ability to predict responses of …

Cosmological Constant As Confining U(1) Charge In Two-Dimensional Dilaton Gravity, Daniel Grumiller, Robert A. Mcnees Iv, Jakob Salzer

Physics: Faculty Publications and Other Works

The cosmological constant is treated as a thermodynamical parameter in the framework of two-dimensional dilaton gravity. We find that the cosmological constant behaves as a U(1) charge with a confining potential, and that such potentials require a novel Born-Infeld boundary term in the action. The free energy and other thermodynamical quantities of interest are derived, from first principles, in a way that is essentially model independent. We discover that there is always a Schottky anomaly in the specific heat and explain its physical origin. Finally, we apply these results to specific examples, like anti-de Sitter–Schwarzschild–Tangherlini black holes, Bañados-Teitelboim-Zanelli black holes …

Effects Of Contaminated St. Lucie River Saltwater Sediments On An Amphipod (Ampelisca Abdita) And A Hard-Shell Clam (Mercenaria Mercenaria), Tham C. Hoang, Gary M. Rand

School of Environmental Sustainability: Faculty Publications and Other Works

The St. Lucie estuary (SLE) ecosystem in South Florida has been shown to be contaminated with metals and pesticides. Our earlier studies also showed that aquatic organisms, especially benthic species in the SLE ecosystem, might be potentially at high risk from copper (Cu) exposure. The objectives of this study were to conduct studies with separate groups of organisms exposed to seven field-collected sediment samples from the St. Lucie River according to standard procedures to evaluate toxicity and tissue concentrations of Cu and zinc (Zn). Short term and longer term whole sediment acute toxicity studies were performed with Ampelisca abdita and …
