Disciplinary Mythologies: A Rhetorical-Cultural Analysis Of Performance Enhancement Technologies In Sports, John Lamothe

John Lamothe

In sports discourse, the relationship between athletics and technology is often paradoxical. On the one hand, modern sports rely on technology at every level, from training and tracking of players to the equipment and apparel used by athletes to the game strategies and playing fields themselves. Nearly all of these technologies are intended to increase athletic performance on some level. And yet, certain performance enhancement technologies can be criticized for being antithetical to the spirit of sports, which is framed as being a strictly natural and pure human endeavor. Using a rhetorical-cultural methodological approach, popular sports discourse is analyzed to …

Nitrogen Fixation Sustained Productivity In The Wake Of The Palaeoproterozoic Great Oxygenation Event, Genming Luo, Christopher K. Junium, Gareth Izon, Shuhei Ono, Nicolas Beukes, Thomas J. Algeo, Ying Cui, Shucheng Xie, Roger E. Summons

Ying Cui

The marine nitrogen cycle is dominated by redox-controlled biogeochemical processes and, therefore, is likely to have been revolutionised in response to Earth-surface oxygenation. The details, timing, and trajectory of nitrogen cycle evolution, however, remain elusive. Here we couple nitrogen and carbon isotope records from multiple drillcores through the Rooihoogte–Timeball Hill Formations from across the Carletonville area of the Kaapvaal Craton where the Great Oxygenation Event (GOE) and its aftermath are recorded. Our data reveal that aerobic nitrogen cycling, featuring metabolisms involving nitrogen oxyanions, was well established prior to the GOE and that ammonium may have dominated the dissolved nitrogen inventory. …

Co2 Levels And Climate Change During Early Eocene Hyperthermals, Ying Cui

Ying Cui

Early Eocene (56 to 33.9 million years ago) is punctuated by a series of rapid and extreme global warming events, known as the ‘hyperthermals’, triggered by massive release of carbon dioxide. Despite the carbon emission rate might have been ten times smaller than the current emission from burning fossil fuels and cement production, the early Eocene hyperthermals are considered one of the best analogues for CO2 concentration projected into the future. The temperature records are well established from deep sea sediments during these hyperthermals, but the CO2 levels in the atmosphere remain poorly known, partly due to the lack of …

Marine Sediment Record From The East Antarctic Margin Reveals Dynamics Of Ice Sheet Recession, Amy Leventer, Eugene Domack, Jennifer Pike, Catherine Stickley, Eleanor Maddison, Stefanie A. Brachfeld, Patricia Manley, Charlie Mcclennen

Stefanie Brachfeld

The Antarctic shelf is traversed by large-scale troughs developed by glacial erosion. Swath bathymetric, lithologic, and chronologic data from jumbo piston cores from four sites along the East Antarctic margin (Iceberg Alley, the Nielsen Basin, the Svenner Channel, and the Mertz-Ninnis Trough) are used to demonstrate that these cross-shelf features controlled development of calving bay reentrants in the Antarctic ice sheet during deglaciation. At all sites except the Mertz-Ninnis Trough, the transition between the Last Glacial Maximum and the Holocene is characterized by varved couplets deposited during a short interval of extremely high primary productivity in a fjordlike setting. Nearly …

This presentation provides an overview of the app's functionality, which includes generating EADs for Virginia Heritage, HTML files for upload to the Libraries website, and MARCXML records for our catalog and OCLC. It also describes the efficiencies and other benefits we have observed from Spaceport's use.

The Mysterious Incident Of The Missing Title: Why Did Titular Concern Vanish From Composition Studies?, John Lamothe

John Lamothe

How much time, if any, do first-year writing instructors spend in class discussing the importance of titles on their students’ papers? Without looking at a mountain of lesson plans or interviewing a plethora of instructors from across the country, it is impossible to know what is and what isn’t commonly taught in first-year composition courses. Admittedly, introductory writing and research classes can vary greatly from institution to institution and even from instructor to instructor within the same department. However, judging by an examination of current First-Year Composition textbooks, Rhet/Comp scholars place little importance on discussing the effect of titles on …

Properties Of New York/New Jersey Harbor Sediments, K. W. Jones, Huan Feng, E. A. Stren, U. Neuhäusler, J. Osán, N. Marinkovic, Z. Song

Huan Feng

Sediments found in waterways around the world may contain toxic compounds of anthropogeilic origin that can harm the environment and human health. As a result, it is often necessary to remove them and find disposal methods that are environmentally and economically acceptable. Here, we report on results obtained in an experimental program to characterize the nature of the sediment contamination. The objective was to gain a better understanding of the properties of the sediments to develop better methods for understanding the fate and transport of the contaminants and for improving methods for their removal from the sediments. Our investigations made …

Urban Environmental Pollution 2010: Trace Metal Dispersion In Soil From Auto-Mechanic Village To Urban Residential Areas In Owerri, Nigeria, Michael A. Nwachukwu, Huan Feng, Jude Alinnor

Huan Feng

Due to poor waste management in mechanic villages (MVs), average metal concentration (mgkg-1) is Pb 1162±572; Mn 864±531; Cu 385±202; Fe 49259±4770; Cd 20±13; Zn 824±190; and Ni 40±35, causing ecological and public health risks in parts of Nigeria. Average metal dispersion (mgkg-1/m) from MVs to residential areas was estimated at 9.2 for Pb; 6.7 for Mn; 6.1 for Zn; 1.5 for Cu; 197 for Fe; 0.3 for Ni; and 0.04 for Cd. This represents a mobility order of Fe>Pb>Mn>Zn>Cu>Ni>Cd, and a pollution order of Pb>Ni>Mn>Zn>Fe>Cu>Cd. MV advantages …

Preparation Of Glass-Ceramics Largely Using Steelmaking Slags And Study On The Effect Of Iron Content On Properties Of Glass-Ceramics, Huan Feng

Huan Feng

Glass-ceramics were prepared using steelmaking industry waste containing high iron content based on powder sintering and crystallization method. Anthracite was used in varying amounts as the reducing agent to recover iron in raw materials. X-ray diffraction analysis (XRD), Fourier Transform Infrared Spectroscopy (FTIR), and Scanning Electron Microscope (SEM) coupled with Energy Dispersive X-ray spectrometer (EDX) were used to study the microstructure of glass-ceramics formed. Bending strength and micro-harness of the samples were compared. When 12g of anthracite was used, ionic iron (Fe 2+ /Fe 3+ ) content was reduced to 4.7% and total iron content was reduced to 8.0% in …

Magnetic Mineral Diagenesis In The River‐Dominated Inner Shelf Of The East China Sea, China, Can Ge, Weiguo Zhang, Chenyin Dong, Yan Dong, Jinyan Liu, Nguyen Thi Thu Hien, Huan Feng, Lizhong Yu

Huan Feng

The inner shelf of the East China Sea is a river-dominated margin characterized by fine-grained mud deposits and a rapid sedimentation rate. Three short sediment cores (similar to 2.7m in length) were examined to characterize spatial variations in magnetic mineral diagenesis. The sediment cores were analyzed for sedimentation rates, magnetic properties, particle size distribution, organic carbon, and total sulfur content. The two more proximal cores with higher sedimentation rates (similar to 2.2cm/yr and similar to 0.96cm/yr) do not exhibit obvious effects of reductive dissolution of magnetite with increasing depth, which is consistent with their lower total sulfur content. The offshore …

Evidence For Exocellular Arsenic In Fronds Of Pteris Vittata, Rupali Datta, Padmini Das, Ryan Tappero, Pravin Punamiya, Evert Elzinga, Shivendra Sahi, Huan Feng, Jeffrey Kiiskila, Dibyendu Sarkar

Huan Feng

The arsenic (As) hyperaccumulating fern species Pteris vittata (PV) is capable of accumulating large quantities of As in its aboveground tissues. Transformation to AsIII and vacuolar sequestration is believed to be the As detoxification mechanism in PV. Here we present evidence for a preponderance of exocellular As in fronds of Pteris vittata despite numerous reports of a tolerance mechanism involving intracellular compartmentalization. Results of an extraction experiment show that 43–71% of the As extruded out of the fronds of PV grown in 0.67, 3.3 and 6.7mM AsV. SEM-EDX analysis showed that As was localized largely on the lower pinna surface, …

Enhancing Digestibility And Ethanol Yield Of Populus Wood Via Expression Of An Engineered Monolignol 4-O-Methyltransferase, Yuanheng Cai, Kewei Zhang, Hoon Kim, Guichuan Hou, Xuebin Zhang, Huijun Yang, Huan Feng, Lisa Miller, John Ralph, Chang-Jun Liu

Huan Feng

Producing cellulosic biofuels and bio-based chemicals from woody biomass is impeded by the presence of lignin polymer in the plant cell wall. Manipulating the monolignol biosynthetic pathway offers a promising approach to improved processability, but often impairs plant growth and development. Here, we show that expressing an engineered 4-O-methyltransferase that chemically modifies the phenolic moiety of lignin monomeric precursors, thus preventing their incorporation into the lignin polymer, substantially alters hybrid aspens’ lignin content and structure. Woody biomass derived from the transgenic aspens shows a 62% increase in the release of simple sugars and up to a 49% increase in the …

Mobile Learning: Implementing A 1 To 1 Ipad Project In A Teacher Preparation Program, Elizabeth Truesdell, Rebecca Birch

Elizabeth Truesdell

This brief paper examines how a teacher preparation program implemented a 1-1 mobile learning initiative with faculty, teacher candidates and their fieldwork supervisors. The initiative proceeded through a three-tiered approach to effectively integrating instructional technology in and outside of the classroom. Researchers employed a mixed method approach to data collection and analysis, which indicated an increased rate of faculty, student teacher and supervisor competency levels in the use of instructional technology. This study fills a gap in research regarding 1-1 iPad initiatives in teacher preparation programs.

Developing Digital Literacy Through Community Engagement, Elizabeth Truesdell, Rebecca Birch

Elizabeth Truesdell

This case study describes how one department of education sought to increase knowledge of digital literacy amongst preservice teachers. Framed by the researchers’ Three-Tiered Model of instructional technology use, this project leveraged a community partnership and the implementation of “instructional rounds” to educate students in digital technologies. The mixed-methods study includes pre- and post-surveys results, structured observations, and student reflections. Initial findings indicate students’ enhanced digital literacy skills and a reciprocally beneficial partnership with teachers and administrators at a local high school. Ultimately, students who participated in this project led a community-wide professional development workshop.

Embryonic Origin And Genetic Basis Of Cave Associated Phenotypes In The Isopod Crustacean Asellus Aquaticus., Hafasa Mojaddidi, Franco E Fernandez, Priscilla A Erickson, Meredith E. Protas

Meredith Protas

Characteristics common to animals living in subterranean environments include the reduction or absence of eyes, lessened pigmentation and enhanced sensory systems. How these characteristics have evolved is poorly understood for the majority of cave dwelling species. In order to understand the evolution of these changes, this study uses an invertebrate model system, the freshwater isopod crustacean, Asellus aquaticus, to examine whether adult differences between cave and surface dwelling individuals first appear during embryonic development. We hypothesized that antennal elaboration, as well as eye reduction and pigment loss, would be apparent during embryonic development. We found that differences in pigmentation, eye …

Viscosity Of Bacterial Suspensions: Hydrodynamic Interactions And Self-Induced Noise, Shawn D. Ryan, Brian M. Haines, Leonid Berlyand, Falko Ziebert, Igor S. Aranson

Shawn Ryan

The viscosity of a suspension of swimming bacteria is investigated analytically and numerically. We propose a simple model that allows for efficient computation for a large number of bacteria. Our calculations show that long-range hydrodynamic interactions, intrinsic to self-locomoting objects in a viscous fluid, result in a dramatic reduction of the effective viscosity. In agreement with experiments on suspensions of Bacillus subtilis, we show that the viscosity reduction is related to the onset of large-scale collective motion due to interactions between the swimmers. The simulations reveal that the viscosity reduction occurs only for relatively low concentrations of swimmers: Further …

An Elastica Model Of The Buckling Of A Nanoscale Sheet Perpendicular To A Rigid Substrate, Shawn D. Ryan, Dmitry Golovaty, Patrick Wilber

Shawn Ryan

We study a variation on the classical problem of the buckling of an elastica. The elastica models a nanoscale sheet that interacts with a rigid substrate by intermolecular forces. We formulate a buckling problem in which the sheet is perpendicular to the substrate and a load is applied to the edge of the sheet further from the substrate. Our study is motivated by problems in nanomechanics such as the bending of a graphene sheet interacting with a rigid substrate by van der Waals forces. After identifying a trivial branch, we combine computation and analysis to determine the stability and bifurcations …
