The Teacher-Student Writing Conference Reimaged: Entangled Becoming-Writingconferencing, Donna Kalmbach Phillips, Mindy Legard Larson

Faculty Publications

This analysis is experimental: we attempt to read data with the work of Karen Barad and in doing so ‘see’ teacher-student writing conferences (a common pedagogy of US elementary school writing) as intra-activity. Data were gathered during teacher-student writing conferences in a grade five US classroom over a six week period. One conference between a researcher and a male Latino student, a Student of Labels, is diffracted. Reading and writing and thinking with Barad disrupts our habitual ways of privileging language as representational. Rather, we consider the material-discursive practices of schooling that produce what comes to matter, leading …

Effects Of Oil On The Rate And Trajectory Of Louisiana Marsh Shoreline Erosion, G Mcclenachan, R. Eugene Turner, A W. Tweel

Faculty Publications

Oil can have long-term detrimental effects on marsh plant health, both above-and belowground. However, there are few data available that quantify the accelerated rate of erosion that oil may cause to marshes and the trajectory of change. Between November 2010 and August 2012, we collected data on shoreline erosion, soil strength, per cent cover of Spartina alterniflora, and marsh edge overhang at 30 closely spaced low oil and high oil sites in Bay Batiste, Louisiana. Surface oil samples were taken one meter into the marsh in February 2011. All high oiled sites in Bay Batiste were contaminated with Macondo 252 …

Retrospective Analysis Of Midsummer Hypoxic Area And Volume In The Northern Gulf Of Mexico, 1985-2011, D R. Obenour, D Scavia, N N. Rabalais, R. Eugene Turner, D R. Obenour

Faculty Publications

Robust estimates of hypoxic extent (both area and volume) are important for assessing the impacts of low dissolved oxygen on aquatic ecosystems at large spatial scales. Such estimates are also important for calibrating models linking hypoxia to causal factors, such as nutrient loading and stratification, and for informing management decisions. In this study, we develop a rigorous geostatistical modeling framework to estimate the hypoxic extent in the northern Gulf of Mexico from data collected during midsummer, quasi-synoptic monitoring cruises (1985-2011). Instead of a traditional interpolation-based approach, we use a simulation-based approach that yields more robust extent estimates and quantified uncertainty. …

Nitrogen And Phosphorus Phytoplankton Growth Limitation In The Northern Gulf Of Mexico, R. Eugene Turner, N N. Rabalais

Faculty Publications

We conducted 158 bioassays to determine phytoplankton growth limitation in the northern Gulf of Mexico and made the following observations. Light limitation occurred where salinity was < 20; at higher salinities, phytoplankton biomass yield became mostly limited by N or by a co-limitation of N plus P (NP). The number of N-limited bioassays was 5 times greater than the P-limited bioassays. NP synergism occurred where salinity was > 20, and represented 59% of all samples that were not light-limited. The interaction of N and P co-limitation was frequently synergistically additive, i.e. the combined effects of N and P limitation together created a greater response than the sum of either separately. The dissolved inorganic nitrogen: phosphate ratio (DIN:Pi) and various concentrations of DIN and Pi did not offer reliable chemical boundaries describing likely areas of exclusive N or P limitation in these bioassays. …

Economic Impact Of Gulf Of Mexico Ecosystem Goods And Services And Integration Into Restoration Decision-Making, Andrew N. Shepard, John F. Valentine, Christopher F. D'Elia, David W. Yoskowitz, David E. Dismukes

Faculty Publications

Sustainability of natural resources requires balancing exploitation and conservation, enabled by management based on the best available scientific and economic information. Valuation of ecosystemgoods and services is an important tool for prioritizing restoration efforts, recognizing the economic importance of conserving natural capital, and raising public awareness about the contribution of healthy ecosystems to social welfare, now and for future generations. The Deepwater Horizon oil spill (DHOS) in 2010 was a Gulf of Mexico ecological and economic disaster adding to decades-long degradation of the region's coastal and marine environment. In 2010, revenues from provisioning ecosystem goods and services generated by the …

The Meaning Of Science In The Copyright Clause, Ned Snow

Faculty Publications

The Constitution premises Congress’s copyright power on promoting “the Progress of Science.” The word Science therefore seems to define the scope of copyrightable subject matter. Modern courts and commentators have subscribed to an originalist view of Science, teaching that Science meant general knowledge at the time of the Framing. Under this interpretation, all subject matter may be copyrighted because expression about any subject increases society’s store of general knowledge. Science, however, did not originally mean general knowledge. In this Article, I examine evidence surrounding the Copyright Clause and conclude that at the Framing of the Constitution, Science meant a system …

The Children And Parents In Focus Project: A Population-Based Cluster-Randomised Controlled Trial To Prevent Behavioural And Emotional Problems In Children, R. Salari, H. Fabian, Ron Prinz, S. Lucas, I. Feldman, Amanda Fairchild, A. Sarkadi

Faculty Publications

Background: There is large body of knowledge to support the importance of early interventions to improve child health and development. Nonetheless, it is important to identify cost-effective blends of preventive interventions with adequate coverage and feasible delivery modes. The aim of the Children and Parents in Focus trial is to compare two levels of parenting programme intensity and rate of exposure, with a control condition to address impact and cost-effectiveness of a universally offered evidence-based parenting programme in the Swedish context. Methods/Design: The trial has a cluster randomised controlled design comprising three arms: Universal arm (with access to participation in …

Regulating In Uncertainty: Animating The Public Health Product Safety Net To Capture Consumer Products Regulated By The Fda That Use Innovative Technologies, Including Nanotechnologies, Genetic Modification, Cloning, And Lab Grown Meat, Katharine A. Van Tassel

Faculty Publications

The past several decades have seen the creation of transformative new technologies that are being used to design innovative consumer product ingredients never seen before in nature. Examples include the use of nanotechnology and genetic modification, and, right around the corner, cloning and lab grown meat. These innovative technologies are harbingers of more pioneering consumer product ingredients to come. The remarkable pace of the development of ground-breaking new technologies means that the population is being steadily exposed to novel ingredients with unknown health risks.

Optimally, the Food & Drug Administration ("FDA") should be regulating these innovative, novel ingredients in consumer …

Tattoos & Ip Norms, Aaron K. Perzanowski

Faculty Publications

The U.S. tattoo industry generates billions of dollars in annual revenue. Like the music, film, and publishing industries, it derives value from the creation of new, original works of authorship. But unlike rights holders in those more traditional creative industries, tattoo artists rarely assert formal legal rights in disputes over copying or ownership of the works they create. Instead, tattooing is governed by a set of nuanced, overlapping, and occasionally contradictory social norms enforced through informal sanctions. And in contrast to other creative communities that rely on social norms because of the unavailability of formal intellectual property protection, the tattoo …

The Use And Misuse Of Biomedical Data: Is Bigger Really Better?”, Sharona Hoffman, Andy Podgurski

Faculty Publications

Very large biomedical research databases, containing electronic health records (HER) and genomic data from millions of patients, have been heralded recently for their potential to accelerate scientific discovery and produce dramatic improvements in medical treatments. Research enabled by these databases may also lead to profound changes in law, regulation, social policy, and even litigation strategies. Yet, is “big data” necessarily better data?

This paper makes an original contribution to the legal literature by focusing on what can go wrong in the process of biomedical database research and what precautions are necessary to avoid critical mistakes. We address three main reasons …

Social studies educators are encouraged to use disability history to move the concept of disability beyond Individualized Education Program (IEP) labels and medical pathology, allowing students to study and better understand the evolving social and cultural context of disability. An examination of disability “models” and the historical evolution of disability language is followed by strategies and resources for incorporating disability history and awareness in the social studies classroom. Ohio social studies educators are encouraged to support a Disability History and Awareness week or month …

Tnt1 Retrotransposon Mutagenesis: A Tool For Soybean Functional Genomics, Yaya Cui, Shyam Barampuram, Minviluz G. Stacey, C. Nathan Hancock, Seth Findley, Melanie Mathieu, Zhanyuan Zhang, Wayne A. Parrott, Gary Stacey

Faculty Publications

Insertional mutagenesis is a powerful tool for determining gene function in both model and crop plant species. Tnt1, the transposable element of tobacco (Nicotiana tabacum) cell type 1, is a retrotransposon that replicates via an RNA copy that is reverse transcribed and integrated elsewhere in the plant genome. Based on studies in a variety of plants, Tnt1 appears to be inactive in normal plant tissue but can be reactivated by tissue culture. Our goal was to evaluate the utility of the Tnt1 retrotransposon as a mutagenesis strategy in soybean (Glycine max). Experiments showed that the …

Seasonal Variation In Corticosterone Receptor Binding In Brain, Hippocampus, And Gonads In House Sparrows (Passer Domesticus), Christine R. Lattin, L. Michael Romero

Faculty Publications

Abstract.-Both baseline and stress-induced concentrations of corticosterone (CORT) vary seasonally in a predictable fashion in many wild birds. Hypotheses about why these patterns exist include the "behavior hypothesis," which predicts that animals will down-regulate stress-induced CORT when CORT-induced behaviors are too likely to cause reproductive failure; and the "preparative hypothesis," which posits that baseline and stress-induced CORT will both be high at times of year with a higher incidence of predictable stressors. We tested predictions made by the behavior and predictive hypotheses about the CORT sensitivity of tissues involved in breeding: whole brain, hippocampus, and gonads. We used radioligand binding …

Physiological Effects Of Tourism And Associated Food Provisioning In An Endangered Iguana, Charles R. Knapp, Kirsten N. Hines, Trevor T. Zachariah, Caro Perez-Heydrich, John B. Iverson, Sandra D. Buckner, Shelley C. Halach, Christine R. Lattin, L. Michael Romero

Faculty Publications

© The Author 2013. Deliberately feeding wildlife is an increasingly popular tourism-related activity despite a limited understanding of long-term impacts on the species being fed. As a result, tourist behaviours that may have adverse impacts on imperiled species have often been encouraged without the necessary evaluation or oversight. Here, we report the responses of Northern Bahamian Rock Iguanas (Cyclura cychlura) to human-visitation pressure and associated food provisioning. We compared a variety of blood chemistry parameters of iguanas subjected to supplemental feeding at popular tourist destinations with iguanas occurring on islands where supplemental feeding does not take place. We demonstrate that …

Intracellular Glucocorticoid Receptors Inspleen, But Not Skin, Vary Seasonally Inwild House Sparrows (Passer Domesticus), Christine R. Lattin, K. Waldron-Francis, L. Michael Romero

Faculty Publications

Over the short-term and at physiological doses, acute increases in corticosterone (CORT) titres can enhance immune function. There are predictable seasonal patterns in both circulating CORT and immune function across many animal species, but whether CORT receptor density in immune tissues varies seasonally is currently unknown. Using radioligand binding assays, we examined changes in concentrations of glucocorticoid receptors (GR) and mineralocorticoid receptors (MR) in spleen and skin in wild-caught house sparrows in Massachusetts during six different life-history stages: moult, early winter, late winter, pre-egg-laying, breeding and late breeding. Splenic GR and MR binding were highest during the pre-laying period. This …

Particulate Matter Containing Environmentally Persistent Free Radicals And Adverse Infant Respiratory Health Effects: A Review, Jordy Saravia, Greg I. Lee, Slawo Lomnicki, Barry Dellinger, Stephania A. Cormier

Faculty Publications

The health impacts of airborne particulate matter (PM) are of global concern, and the direct implications to the development/exacerbation of lung disease are immediately obvious. Most studies to date have sought to understand mechanisms associated with PM exposure in adults/adult animal models; however, infants are also at significant risk for exposure. Infants are affected differently than adults due to drastic immaturities, both physiologically and immunologically, and it is becoming apparent that they represent a critically understudied population. Highlighting our work funded by the ONES award, in this review we argue the understated importance of utilizing infant models to truly understand …

Temperature And Co2 Additively Regulate Physiology, Morphology And Genomic Responses Of Larval Sea Urchins, Strongylocentrotus Purpuratus, Jacqueline L. Padilla-Gamiño, Morgan W. Kelly, Tyler G. Evans, Gretchen E. Hofmann

Faculty Publications

Ocean warming and ocean acidification, both consequences of anthropogenic production of CO2, will combine to influence the physiological performance of many species in the marine environment. In this study, we used an integrative approach to forecast the impact of future ocean conditions on larval purple sea urchins (Strongylocentrotus purpuratus) from the northeast Pacific Ocean.In laboratory experiments that simulated ocean warming and ocean acidification, we examined larval development, skeletal growth, metabolism and patterns of gene expression using an orthogonal comparison of two temperature (138C and 188C) and pCO2 (400 and 1100 matm) conditions. Simultaneous exposure to increased temperature and pCO2 significantly …

An Analysis Of Thaumarchaeota Populations From The Northern Gulf Of Mexico, Bradley B. Tolar, Gary M. King, James T. Hollibaugh

Faculty Publications

We sampled Thaumarchaeota populations in the northern Gulf of Mexico, including shelf waters under the Mississippi River outflow plume that are subject to recurrent hypoxia. Data from this study allowed us to: (1) test the hypothesis that Thaumarchaeota would be abundant in this region; (2) assess phylogenetic composition of these populations for comparison with other regions; (3) compare the efficacy of quantitative PCR (qPCR) based on primers for 16S rRNA genes (rrs) with primers for genes in the ammonia oxidation (amoA) and carbon fixation (accA, hcd) pathways; (4) compare distributions obtained by qPCR with the relative abundance of Thaumarchaeota rrs …

Metabolic Preconditioning Of Mammalian Cells: Mimetic Agents For Hypoxia Lack Fidelity In Promoting Phosphorylation Of Pyruvate Dehydrogenase, Apurva Borcar, Michael A. Menze, Mehmet Toner, Steven C. Hand

Faculty Publications

Induction of HIF-1α by oxygen limitation promotes increased phosphorylation and catalytic depression of mitochondrial pyruvate dehydrogenase (PDH) and an enhanced glycolytic poise in cells. Cobalt chloride and desferrioxamine are widely used as mimics for hypoxia because they increase the levels of HIF-1α. We evaluated the ability of these agents to elicit selected physiological responses to hypoxia as a means to metabolically precondition mammalian cells, but without the detrimental effects of hypoxia. We show that, while CoCl2 does increase HIF-1α in a dose-dependent manner, it unexpectedly and strikingly decreases PDH phosphorylation at E1α sites 1, 2, and 3 (Ser293, Ser 300, …

Both habitat filtering and dispersal limitation influence the compositional structure of forest communities, but previous studies examining the relative contributions of these processes with variation partitioning have primarily used topography to represent the influence of the environment. Here, we bring together data on both topography and soil resource variation within eight large (24-50 ha) tropical forest plots, and use variation partitioning to decompose community compositional variation into fractions explained by spatial, soil resource and topographic variables. Both soil resources and topography account for significant and approximately equal variation in tree community composition (9-34% and 5-29%, respectively), and all environmental variables …

Biotechnology For Mechanisms That Counteract Salt Stress In Extremophile Species: A Genome-Based View, Ray A. Bressan, Hyeong Cheol Park, Francesco Orsini, Dong Ha Oh, Maheshi Dassanayake, Gunsu Inan, Dae Jin Yun, Hans J. Bohnert, Albino Maggio

Faculty Publications

Molecular genetics has confirmed older research and generated new insights into the ways how plants deal with adverse conditions. This body of research is now being used to interpret stress behavior of plants in new ways, and to add results from most recent genomics-based studies. The new knowledge now includes genome sequences of species that show extreme abiotic stress tolerances, which enables new strategies for applications through either molecular breeding or transgenic engineering. We will highlight some physiological features of the extremophile lifestyle, outline emerging features about halophytism based on genomics, and discuss conclusions about underlying mechanisms. © 2012 Korean …

Copper Β-Trinitrocorrolates, Manuela Stefanelli, Sara Nardis, Frank R. Fronczek, Kevin M. Smith, Roberto Paolesse

Faculty Publications

The β-nitration reaction carried out on the corrole macrocycle has been shown to be extremely regioselective, although the reduced symmetry of the macrocycle could potentially lead to a huge number of possible regioisomers. We recently reported that the careful use of AgNO2/NaNO2 as a nitrating system enabled the achievement in good yields of mono- and dinitro-derivatives on both corrole free base and its copper complex, proving to be an efficient and cost-effective method. In this work, we present a detailed study of the scope of this method using TtBuCorrH3 as a model corrole. A further increase of the oxidant pushes …

A New Foundation For The Propensity Interpretation Of Fitness, Charles H. Pence, Grant Ramsey

Faculty Publications

The propensity interpretation of fitness (PIF) is commonly taken to be subject to a set of simple counterexamples. We argue that three of the most important of these are not counterexamples to the PIF itself, but only to the traditional mathematical model of this propensity: fitness as expected number of offspring. They fail to demonstrate that a new mathematical model of the PIF could not succeed where this older model fails. We then propose a new formalization of the PIF that avoids these (and other) counterexamples. By producing a counterexample-free model of the PIF, we call into question one of …
